    The invention relates to a portable device for removing feces, in particular animal feces such as dog feces or cat feces.
    DE 10 2017 005 058 A1 discloses a washable hand-held device for picking up, transporting and environmentally friendly removal of dog excrement. The hand-held device has grippers made of elastic material with molded film hinges. The grippers can be turned inside out so that they can be washed off by the water when the dog excrement is deposited in a toilet.
    [0003] EP 2 341 769 B1 discloses a dog excrement remover with a shovel for picking up the dog excrement and with a spray device to transport the dog excrement down from the shovel.
    The devices known from the prior art are set up to take up dog excrement and store it in another suitable location. The disadvantage here is that the dog poop, if it cannot be transported to a toilet, is deposited outdoors. Depending on the weather, the dog excrement stays there for a very long time and on the one hand develops unpleasant smells and on the other hand is annoying for people who move outdoors, for example walkers or recreational athletes.
    [0005] For a long time, dog owners have been asked by local authorities and city administrations to take up dog waste in plastic bags and dispose of it in containers provided for this purpose. As a result, millions of plastic bags are used every day to dispose of dog poop. Often the plastic bags with the dog poop they contain are thrown away due to the lack of a sufficient number of receptacles on the promenades in nature or in the city or community area. Since these bags do not rot and are annoying in the city or municipality, they ultimately have to be collected and disposed of again at great expense, for example by municipal employees.
    Despite these high financial and personnel expenses by the municipalities, the environmental situation is worse than before. For example, the proportion of plastic in nature has increased millions of times to the detriment of agriculture. In agriculture, discarded plastic bags with dog feces are picked up by harvesting machines or mowing machines and can thus get into feed and the food cycle.
    The concept of today's dog excrement disposal consumes about 20-30 million plastic bags daily in 20-30 million dogs in Germany. It is to be expected that a high proportion of these, an estimated 50-60%, of these dog waste bags and their contents will not be properly disposed of, but will initially remain in the environment.
    [0008] The consequences for the municipalities are high costs due to additional effort without a positive end result. The disposal of dog waste with plastic bags is inefficient and means an extremely high burden on the environment.
    In view of this situation and based on the known prior art, it is therefore an object of the present invention to provide a device for removing feces that avoids disturbing disturbances to others as far as possible and does not require long transport of the feces. In addition, the effort and costs for municipalities and cities are to be reduced and sustainable disposal by the dog handler on site and a reduction in plastic waste are to be achieved.
    The invention is achieved by a portable device according to claim 1.
    The portable device is set up in particular to remove animal droppings, such as dog droppings or cat droppings. A portable device is to be understood here as a device that a person can pick up and carry with him without additional aids. The portable device preferably has no rollers or other means that are supported on the ground during transport.
    The portable device has a handle and a comminution chamber arranged in a longitudinal direction at a distance from the handle. The comminution chamber is connected to the handle via a suitable connecting device. Preferably, the distance between the handle and the shredding chamber in the operational state of the portable device is so large that the shredding chamber can be arranged on the ground and the handle is so far away from the ground that it can be used by a person standing on the ground can be operated by hand. The handle is then, so to speak, at about hip height. The distance between the handle and the ground, when the comminution chamber is arranged on the ground, is about 60 cm to 100 cm or up to 120 cm in the embodiment.
    The portable device has a wall that delimits the crushing chamber. A coverable opening in the wall leads into the shredding chamber. An edge of the wall limits the coverable opening. Either the surface on which the faeces is located or a cover arranged on the portable device and in particular the wall, which can be moved between an open position and a cover position, can serve to cover the coverable opening.
    The portable device also has a liquid pressure unit which is fluidically connected to a liquid nozzle. The liquid pressure unit preferably has a liquid container and a pump that can in particular be driven by an electric motor. The nozzle opening of the liquid nozzle is directed into the comminution chamber in order to be able to direct at least one jet of liquid onto the feces located or received there. On the suction side, the pump is fluidically connected to the liquid container and on the pressure side fluidically connected to the liquid nozzle.
    The liquid pressure unit can also have a pressure accumulator for the liquid. The liquid pressure can be generated, for example, by a gas volume under pressure in or on the pressure accumulator. The pressure of the gas volume can be generated manually by a pumping device or by means of a motor-pump unit, which in particular has an electric motor.
    When operating the pump or when establishing the fluid connection with the pressurized liquid, a jet of liquid is generated via the nozzle and directed onto the feces arranged in the crushing chamber. The pressure of the liquid and / or the design of the liquid nozzle are such that the at least one generated liquid jet is sufficient to crush the manure. The feces are broken up into a multitude of particles, so to speak, which mix with the liquid and form a flowable mixture, like a suspension. This flowable mixture can seep into an unsealed subsurface, which is supported by the liquid used. As a result, the feces are removed quickly and are not harmful to others. Dog owners in particular can carry the portable device with them and dispose of feces quickly on site, especially in the wild.
    The liquid nozzle can be driven to rotate during operation during the generation of the liquid jet. The rotating drive of the liquid nozzle can be brought about by a drive which also drives an existing pump and / or by the liquid flow. Additionally or alternatively, the liquid nozzle and / or the pump and / or a hydraulic unit between the pump and the liquid nozzle can be designed in such a way that a pulsating liquid jet is created.
    The liquid pressure unit or the pump is preferably set up to generate a liquid pressure of at least 15 bar or at least 20 bar or at least 50 bar or at least 100 bar.
    The liquid container or pressure accumulator preferably has a capacity of at least 200-300 ml. The liquid container can also preferably have a maximum capacity of 500-600 ml, since this amount of liquid is sufficient to crush the feces and / or then rinse the crushing chamber and the device remains compact due to the limited capacity.
    The liquid used is preferably water. A biodegradable agent, for example cleaning agent or disinfectant, can optionally be added to the water.
    In one embodiment, the comminution chamber is, so to speak, open at the bottom. The coverable opening is on the side of the wall that faces away from the handle. In this embodiment, the wall can be bell-shaped. The wall encloses the comminution chamber in a circumferential direction around the longitudinal direction and on the side of the comminution chamber facing the handle. With this design, the wall can be pulled over the manure so that the opening is covered by the ground. Then the pump can be operated and the manure can be shredded in the shredding chamber. This design is particularly suitable when the manure is on an unsealed surface.
    In a further embodiment of the portable device, the crushing chamber is open to the side in an approximately at right angles to the longitudinal direction. The comminution chamber and the wall delimiting the opening also have a bottom section which delimits the comminution chamber at the bottom. In this embodiment it is particularly expedient if a cover is present that can be moved, in particular pivoted, between an open position and a cover position. To receive the manure in the crushing chamber, the crushing chamber can be placed on the ground adjacent to the manure in such a way that the coverable opening faces the manure. By moving the cover from the open position into the closed position, the manure can be picked up through the adjacent coverable opening in the shredding chamber. With this design, the excrement can be picked up - for example from a sealed surface - and first brought to a point where it can be crushed and seeped into the ground or is better possible than at the point where the excrement was taken up. Then the pump can be started and the manure can be crushed and the resulting flowable mixture seeps into the ground.
    The comminution chamber can optionally be closed in a fluid-tight manner by the cover in the covering position, but this does not necessarily have to be the case. The cover can also only represent a splash guard.
    In a working position of the portable device is feces inside the shredding chamber and the coverable opening is covered. As explained, the covering can be covered either by the surface on which the excrement is located or by a cover of the portable device. In this working position, the at least one liquid jet is generated - in particular by operating the pump - and the manure is crushed.
    Preferably, the portable device has a pretensioning device which generates a pretensioning force acting on the cover, so that the cover is urged into the covering position. At least one spring, for example, can be used as the prestressing device.
    It is also advantageous if there is an actuating unit by means of which the cover can be moved into the open position against the biasing force of the biasing device. The actuation unit preferably has an actuation means which is arranged in the area of the handle.
    It is also advantageous if there is a locking device to hold the cover in the open position. The locking device is designed in particular in such a way that the locked state can be canceled manually in order to be able to move the cover from the open position into the cover position. The locking device can interact directly with the cover or indirectly with the cover, for example by means of the actuating unit. For example, the actuation unit can be locked in a position in which the actuation unit holds the cover in the open position.
    [0028] The cover is preferably arranged or mounted on the wall, in particular mounted pivotably. The pivot axis preferably extends obliquely or at right angles to the longitudinal direction. A pivoting movement of the cover makes it particularly easy to move feces when moving the cover into the covering position at least partially through the coverable opening into the comminution chamber.
    In another preferred embodiment, the cover is connected to a handle part. The cover and the handle part form a separately manageable unit which can preferably be detachably attached to the wall and / or a connecting part 35 between the handle and the wall. In this embodiment, the portable device forms, in particular, two separately manageable units with the wall delimiting the comminution chamber, a connecting part and the handle on the one hand and the cover with the handle part on the other. Using these two separately manageable units, manure can be picked up in the shredding chamber in a similar way to a broom and dustpan.
    The cover preferably has an elastic lip on a lower edge. Alternatively or additionally, an elastic lip can be provided on a base part adjacent to the coverable opening. This improves the collection of feces in the shredding chamber.
    It is also advantageous if there is a guide for the cover on the wall adjacent to the coverable opening. The cover can be moved along the guide by means of the handle part. In particular, the cover can be displaced linearly along the guide, for example essentially vertically. In this way, the cover can be moved along the guide into the cover position or out of the cover position.
    In a preferred embodiment there is an electric motor which is set up to drive the pump. The pump and the electric motor form a motor-pump unit that can be controlled electrically. An electrical switch can be provided on the handle in order to switch on or off the electric motor driving the pump. Additionally or alternatively, further setting means can be arranged on the handle, for example in order to set the delivery rate of the pump. The delivery rate of the pump can take place either by a controllable pump and / or by a controllable electric motor. The delivery rate of the pump can be adjusted, for example, by varying the speed or the torque of the electric motor.
    In one embodiment, the portable device can have an energy store, in particular a rechargeable energy store. The energy store can provide electrical energy for the electric motor to drive the pump. The energy store is preferably arranged to be removable so that it can be arranged and charged in an external charger. Additionally or alternatively, an electrical connection can be present on the portable device in order to connect a charger without having to remove the energy store from the portable device.
    In an advantageous embodiment, the liquid container is arranged between the handle and the comminution chamber and is preferably arranged to be removable. The liquid container preferably has a flap, a lid or some other closure for closing a filling opening which is provided for filling in liquid. The liquid container can be connected to the suction side of the pump via a suitable fluid connection. In the case of a removable liquid container, this preferably has a releasable check valve at a liquid outlet, so that no liquid escapes when it is removed and the valve is automatically unlocked when the mechanical connection is established, so that a fluid connection between the liquid container and the suction side of the pump is possible.
    It is also advantageous if the pump is arranged adjacent to the liquid container, for example between the liquid container and the comminution chamber or the liquid nozzle. As a result, the fluidic connections between the liquid container and the liquid nozzle can be kept very short.
    [0036] The portable device can form a structural unit. The handle, the liquid container, the pump, the liquid nozzle and the shredding chamber, i.e. the wall and optionally the cover, form a jointly manageable unit when the portable device is in the operational state. Individual components of this portable device can be removable or interchangeable. In the operational state, when the components form an assembly, the entire assembly can be picked up and handled using the handle.
    Another aspect of the invention relates to a method for removing feces, in which in particular the portable device described above is used. To crush or remove faeces, in particular dog or cat faeces, the faeces are arranged in the crushing chamber by manipulating the portable device. This manipulation can take place in that a downwardly open comminution chamber with the wall delimiting the comminution chamber is placed over the manure. In this embodiment, the wall is preferably bell-shaped. By pulling the bell-shaped wall over the manure, the coverable opening that opens into the shredding chamber is covered by the subsurface. The device is then in its working position and the manure can be shredded via the at least one jet of liquid which is directed at the manure in the shredding chamber. The flowable mixture of excrement particles and liquid can seep into the subsoil. This method is particularly suitable for breaking up manure on unsealed surfaces.
    In another embodiment of the method, the portable device for arranging the feces in the crushing chamber is handled such that the wall delimiting the crushing chamber with the coverable opening is positioned adjacent to the feces on the ground and then moving a cover from an open position in a covering position causes the manure to be arranged inside the crushing chamber. In this embodiment, the cover can serve as a slide or shovel to receive the manure in the crushing chamber. In this case, the opening is not covered by the substrate, but by the cover in the covering position.
    After the manure is in the crushing chamber, the portable device is operated at a suitable location for crushing the manure, in particular on a non-sealed surface. At least one jet of liquid, in particular a jet of water, is generated which emerges from a liquid nozzle that is directed into the comminution chamber and onto the manure arranged there. The at least one jet of liquid causes the droppings to be broken up into particles, which mix with the liquid and can seep into an unsealed subsurface. This embodiment of the method is particularly suitable when it is located on a sealed surface.
    In all of the above embodiments of the device and the method, a type of suspension is generated by means of the at least one liquid jet, so to speak, which can be absorbed by the substrate. The manure therefore does not remain in nature for a long time and annoyance to other people is avoided.
    After the crushing and removal of the feces-liquid mixture from the crushing chamber, the pump can optionally be operated further to clean the crushing chamber or the components of the portable device delimiting the crushing chamber, for example the wall and the cover.

    In Figure 1, a block diagram of an embodiment of a portable device 20 is illustrated. The portable device 20 is set up to crush and thus remove feces 21 and in particular animal feces, for example from dogs or cats, using at least one pressurized liquid jet. The removal of the excrement 21 is based on the principle that the excrement 21 is broken down into small particles, mixed with the liquid of the at least one liquid jet directed thereon and forms a flowable mixture in the manner of a suspension that seeps into an unsealed substrate 22 can. For this purpose, the device 20 has a liquid pressure unit which provides the pressurized liquid. According to the example, the liquid pressure unit has a liquid container 23, a pump 24 and a liquid nozzle 25 with a nozzle opening 26. The pump 24 is fluidically connected on its suction side to the liquid container 23 and on its pressure side to the liquid nozzle 25.
    The device 20 has a wall 28 which delimits a comminution chamber 27. The wall 28 also delimits a coverable opening 29 which opens into the comminution chamber 27 and opens the comminution chamber 27 outward to the environment. The nozzle opening 26 is directed into the comminution chamber 27.
    In the exemplary embodiment, the pump 24 is driven by a motor via an electric motor 30. The electrical energy for operating the electric motor 30 is provided via an energy store 31. The energy store 31 is preferably a rechargeable electrical energy store, for example a rechargeable accumulator. A manually operable electrical switch 32 is connected in series between the energy store 31 and the electric motor 30. The electric motor 30 for driving the pump 24 can be switched on or off by means of the electric switch 32. If the pump 24 is driven, liquid is conveyed from the liquid container 23 to the liquid nozzle 25 and exits via the nozzle opening 26 and into the comminution chamber 27. The nozzle opening 26 of the liquid nozzle 25 is oriented in such a way that a predetermined area in the comminution chamber 27 is covered by the one or more liquid jets 33. If there is excrement 21 in this area, it is broken up into particles by the at least one liquid jet 33. The liquid is ejected in a liquid jet 33 or in several liquid jets 33, depending on the configuration of the liquid nozzle 25 or the nozzle opening 26. In FIG. 1, several of the liquid jets 33 are illustrated schematically by way of example.
    Water is preferably used as the liquid, and components such as cleaning agents, disinfectants or the like can also be added to the water. The additives optionally added to the water are preferably biodegradable.
    The portable device 20 has a handle 33. The handle 33 is arranged in a longitudinal direction L at a distance from the wall 28 or the crushing chamber 27. The distance between the handle 33 and the wall 28 or crushing chamber 27 is selected such that the handle 33 is at a height that is easily accessible for a standing person when the wall 28 or the portable device 20 is placed on the ground 22, for example at a height of 60 to 120 cm above the ground 22.
    In the exemplary embodiment shown schematically in FIG. 1, the wall 28 is closed in a circumferential direction U about the longitudinal direction L. The wall 28 also closes the comminution chamber 27 in the direction of the handle 33. The coverable opening 29 is located on the side of the comminution chamber 27 opposite the nozzle opening 26, so that the opening 29 faces away from the handle 33. The wall 28 is configured in the shape of a bell or a pot. The wall 28 is preferably only open to the outside through the coverable opening 29.
    The portable device 20 with the handle 33, the liquid container 23, the pump 24, the electric motor 30, the energy store 31, the wall 28, the crushing chamber 27, and the liquid nozzle 25 can form a jointly manageable unit, as it does is illustrated in the exemplary embodiments according to FIGS. 2 and 5 and 9. All components of the structural unit can be moved or handled via the handle 33 when the portable device 20 is in an operational state.
    In an alternative embodiment, some components or assemblies of the portable device 20 can be arranged in a portable bag 24, for example a belt bag, a backpack, a shoulder bag or the like. For example, the energy store 31, the electric motor 30, the pump 24 and the liquid container 23 can be arranged in the portable bag 34. The portable bag 24 can be electrically and / or fluidly connected to the liquid nozzle 25. The wall 28 delimiting the comminution chamber 27 can be connected to the handle 33 via a rod-shaped connecting part 35. As illustrated by way of example in FIG. 10, the connecting part 35 can, for example, be telescopic.
    In this embodiment, the electrical switch 32 can be arranged on or in the portable bag 34. In this case, an electrical connection between the portable bag 34 and the handle 33 can be omitted. If the electrical switch 32 is arranged on the handle 33, an electrical connection between the electrical switch 32 and the energy store 31 or the electric motor 30 is also required.
    In FIG. 10, a fluidic line connection 36 between the liquid container 23 in the portable bag 34 and the liquid nozzle 25 is illustrated by way of example. The electrical conductor can be designed separately from a fluidic line connection 36, for example in the form of a spiral cable 37 or another electrical line between the portable bag 34 and the switch 32.
    On the portable bag 34, a holster 38 for arranging the assembly arranged outside the portable bag 34 comprising the handle 33, the connecting part 35 and the wall 28 can optionally be present. In particular, the connecting part 35 can be detachably arranged on the portable bag 34 via the holster 38.
    An embodiment of the portable device 20, in which all structural units form an assembly, is illustrated in FIG. A housing 39 is present there adjacent to the handle 33 and is connected to the wall 28 via the connecting part 35. A fluid connection between the pump and the liquid nozzle 25 can run within the connecting part 35. The liquid container 23, the pump 24, the electric motor 30 and the energy store 31 are accommodated in the housing 39. The housing 39 can be opened or closed via a housing flap or a housing cover 40, so that access to the liquid container 23 and the energy store 31 as well as the other components is possible. As an alternative to this, a filling opening for filling liquid into the liquid container 23 and an electrical connection for charging the energy store 31 could also be present in the housing 39, accessible from the outside, so that an opening in the housing 39 that can be closed by a housing cover 40 for filling the liquid container 23 and can be omitted for charging the energy store 31.
    In the embodiments of the portable device 20 described so far, the coverable housing opening 29 is located on the side facing away from the handle 33. This embodiment of the portable device 20 is particularly suitable for shredding and, so to speak, liquefying excrement 21 which is located on an unsealed surface 22. The device is used as follows: the portable device is brought into an operational state by filling the liquid container with liquids and storing sufficient electrical energy in the energy store 31. If feces 21 are to be crushed, the device is arranged above the feces 21 and the wall 28 is placed over the feces 21 so that the coverable opening 21 is covered by the substrate 22 on which the feces 21 are located. The portable device 20 is then in a working position A, as is illustrated, for example, in FIGS. 1, 9 and 10. In this working position A, the electrical switch 32 is actuated, so that the pump 24 is driven by the electric motor 30. As a result, liquid is conveyed from the liquid container 23 to the liquid nozzle 25 and there one or more liquid jets 33 emerge at the nozzle opening 26 and are directed at the feces 21 in the crushing chamber 27. The excrement 21 is crushed by the energy contained in the liquid jets 33 and mixes with the liquid. The excrement 21 is, so to speak, liquefied or a type of suspension of excrement particles and liquid is formed. This mixture of liquid and excrement particles can seep into the ground 22. The infiltration is brought about or supported by the liquid, which sufficiently moisturizes the substrate 22 even when it is dry and enables infiltration.
    Subsequently, by actuating the electrical switch 32 again, rinsing can be carried out with liquid in order to free the comminution chamber 27 from any fecal residues.
    In FIGS. 2 to 5, a further exemplary embodiment of the portable device 20 is illustrated. In this exemplary embodiment, the portable device 20 can be dismantled into individual modules which can be connected to one another. FIG. 2 shows a front view in the operational state, while FIGS. 4 and 5 are each a side view in the operational state. FIG. 3 shows a non-operational state in which the portable device 20 is dismantled into individual modules or individual parts. The dismantling of the portable device 20 can be realized in all disclosed embodiments. The individual parts or modules can be detachably connected to one another via screw or bayonet connections.
    As shown schematically in Figure 3, four modules are formed, for example. The electrical energy store 31 and the liquid container 23 each form a module.
    Another module is formed by the components delimiting the comminution chamber 27, in the exemplary embodiment the wall 28 and a cover 45 arranged on the wall 28. The cover 45 is designed to move between an open position I (FIG. 5) and a cover position II (Figures 2 and 4) to be moved, which will be explained in more detail below.
    Another module is formed by the remaining components, including the pump 24, the electric motor 30, the connecting part 35 and the handle 33. An actuating unit 46, which is designed to actuate the cover 45, is also arranged on this module. In addition, a locking device 47 can be present on this module, which interacts with the actuation unit 46 in order to hold the cover 45 in the open position I. According to the example, the locking device 47 is formed by an eyelet which is open at one point and into which an actuating part 49 of the actuating unit 46 can be hooked when the cover 45 is in the open position I (FIG. 5).
    In this embodiment, the coverable opening 29 is not aligned on the lower side, but laterally with respect to the longitudinal direction L. The wall 28 thus has a wall section which forms a bottom part 50 which is arranged opposite one another at a distance from the liquid nozzle 25. The coverable opening 29 adjoins the bottom part 50 of the wall 28. The coverable opening 29 thus opens the comminution chamber 27 in a direction which is oriented obliquely and, according to the example, at right angles to the longitudinal axis L.
    On the wall 28, the cover 45 is pivotally mounted in the embodiment at a distance from the bottom part 50 via a joint or a hinge. The pivot axis S extends obliquely and, for example, at right angles to the longitudinal direction L (FIGS. 2 and 3). The cover 45 is designed in the manner of a shovel, for example, and engages over an edge area of the wall 28 adjoining the coverable opening 29 when the cover 45 is in the cover position II (FIG. 4). In the open position I, the cover 45 exposes the coverable opening 29 at least in an area adjoining the base part 50 and preferably predominantly completely (FIG. 5).
    As is illustrated schematically in FIGS. 4 and 5, a pretensioning device 51 can be present in order to generate a pretensioning force which urges the cover part 25 into the cover position II. The pretensioning device 51 can be supported, for example, on the wall 28 and on the cover 45 and generate the pretensioning force by means of an elastic deformation force. The pretensioning device 45 is formed, for example, by one or more springs 52. In the exemplary embodiment, the pretensioning force is generated by a tensile force of the at least one spring 52. In the exemplary embodiment illustrated in FIGS. 4 and 5, the at least one spring 52 is located outside the comminution chamber 27. It can, for example, be designed as a tension spring and act on the cover 45 at a distance from the pivot axis S and the other end on the wall 28 support so that a torque in the direction of the cover position II about the pivot axis S is generated. Other types of springs can also be used. For example, the joint or hinge can be arranged on a leg spring. By arranging the pretensioning device 51 outside the comminution chamber 27, contamination of the pretensioning device 21 is avoided. In an alternative embodiment, the pretensioning device 51 can also be arranged within the comminution chamber 27.
    The actuation unit 46 has a tension member 56 which is connected at one end to the cover 45 at a distance from the pivot axis S and has the actuation part 49 at the other end. By pulling on the actuating part 49, the cover 45 can be pivoted about the pivot axis S from the cover position II into the open position I against the biasing force. If the cover part 45 has reached the open position I, the actuating part 49 can be locked with the aid of the eyelet 48 forming the locking device 47, thereby preventing the cover 45 from pivoting back into the cover position II.
    Other types of locking devices 47 can also be used. For example, the cover 45 can be held in the open position I by a magnetic force of a magnet 57 which is arranged immovably in the pivoting direction of the cover 45 about the pivot axis and with which the cover 45 comes into contact in the open position I. Such a magnet 57 is illustrated schematically in FIG. 5 merely by way of example. In this embodiment, the eyelet 48 can be omitted. To release the cover 45 from the open position I, for example, pressure can be exerted on the cover 45 with the foot, an object or on the hand until a torque is generated that is greater than the holding force of the magnet 57 and the cover 45 with the support of the biasing force pivots back from the open position I into the cover position II. Various other locking devices 47 can also be implemented.
    According to the example, the pump 24 and the electric motor 30 are arranged adjacent to and here below the liquid container 23. The pump 24 and the electric motor 30 are arranged, for example, between the liquid container 23 and the comminution chamber 27 or the liquid nozzle 25. The liquid container 23 is preferably arranged between the handle 33 and the pump 24 or the electric motor 30.
    A portable device 20 according to Figures 2 to 5 is used as follows: In the operational state, the cover 45 is brought into the open position I and the bottom part 50 of the wall 28 is placed adjacent to the manure 21 on the ground 22 so that the coverable opening 29 is located immediately adjacent to the excrement 21 (Figure 5). The cover 45 is initially held in the open position I by the locking device 47. By releasing the lock, the pre-tensioning force of the pre-tensioning device 51 moves the cover 45 from the open position I to the cover position II and picks up the excrement 21 under the action of a shovel or slider, so that it is finally in the shredding chamber 27.
    Subsequently, the portable device 20 with the feces 21 received in the crushing chamber 27 can be brought to a location particularly suitable for the crushing, in particular a location where the crushing and seepage of the liquid-fecal mixture into the ground 22 is particularly important is quite possible and least disturbing, for example in loose soil beneath a bush or the like. The electrical switch 32 is then actuated and - as already explained above - at least one liquid jet 33 is generated which comminutes the feces 21 in the comminution chamber 27. The comminution chamber 27 is not designed to be fluid-tight. In particular, the connection between the wall 28 and the cover 45 enables liquid to escape. In addition, one or more openings can also be present on the underside, for example in the bottom part 50, in order to enable sufficiently small particles of the faeces 21 that are mixed with liquid to drain off. Finally, after the manure 21 has been sufficiently or completely crushed, the cover 45 is brought into the open position I, for example by actuating the actuating unit 46 (pulling the actuating part 49). The remaining manure-liquid mixture can run out of the comminution chamber 27.
    Subsequently, by actuating the electrical switch 32 again, it is possible to rinse with liquid in order to free the comminution chamber 27 of any fecal residues. For this purpose, the cover 45 can first be moved back into the cover position II.
    A further exemplary embodiment of the device 20 is illustrated in FIGS. 13 and 14. The cover 45 is provided with a separate handle part 60 which, according to the example, is designed in the shape of a rod. In particular, the length of the handle part in the longitudinal direction L is chosen such that the handle part 60 can be comfortably grasped by a person standing on the ground. On the lower side opposite the handle part 60, the cover 45 can have an elastic lip 61 or rubber lip. Additionally or alternatively, such an elastic lip can also be arranged on the bottom part 50 adjacent to the coverable opening 29.
    The handle part 60 and the cover 45 form a unit that can be handled separately. With the help of this unit, excrement 21 can be pushed into the shredding chamber 27. Such a situation is illustrated schematically in FIG.
    In order to bring the cover 45 into the cover position II, a guide 62 is arranged on the wall 28 adjacent to the coverable opening 29. In the exemplary embodiment, the guide 62 has two rails 63 running parallel to one another, which extend along the coverable opening 29 approximately in the vertical direction or in the longitudinal direction L. The cover 45 can be slid from above along the guide or the rails 63 until the coverable opening 29 is covered in the cover position II (FIG. 14). In this position, the handle part 60 can be arranged on a holder 64. The bracket 64 is located on a suitable component or module of the device 20, for example on the connecting part 35 or on the liquid container 23 or on the energy store 31 or on the motor 30 or on the pump 31, depending on which component or module is in the operational state on a suitable one Place is arranged accessible.
    The embodiment of the device 20 according to Figures 13 and 14 is used in principle as the device 20 according to Figures 2-5. The manure 21 can be conveyed into the comminution chamber 27 by means of the cover 45. If the manure 21 is in the crushing chamber 27, the cover 45 is brought into the cover position II by sliding it along the guide 62. The excrement 21 can then be crushed into particles within the crushing chamber 27 and, so to speak, liquefied. The cover 45 can then be moved at a suitable point from the cover position II into an open position so that the mixture of liquid and particles of the feces 21 can be removed from the comminution chamber 27. As described above, the comminution chamber 27 can then be flushed by further actuation of the switch 32.
    This embodiment of the portable device according to Figures 2 to 5, 13 and 14 is particularly suitable for use when excrement 21 has been deposited on a sealed surface. The excrement 21 can then first of all be picked up and conveyed onto an unsealed subsurface 22 in order to crush it there and allow it to seep into the subsoil 22.
    Instead of seeping into the ground, the excrement 21, which has been broken up into particles, can also be introduced with the liquid into a gully, a septic tank or some other suitable device.
    In Figures 6 to 8, a further embodiment of the portable device 20 is illustrated in the manner of a block diagram. As in the exemplary embodiments according to FIGS. 1, 9 and 10, the coverable opening 29 is located on the underside. In this embodiment, the wall 28, which delimits the comminution chamber 27, is enclosed by an additional outer wall 58. The outer wall 58 does not have to completely surround the wall 28, but is part of the actuation unit 46 and, for example, can be rotated in the circumferential direction U relative to the wall 28. By rotating the outer wall 58 in the circumferential direction U relative to the wall 28, the cover 45 can be switched between the open position I and the closed position II. In this embodiment, the cover 45 is designed in the manner of an annular diaphragm and surrounds the coverable opening 29, as is illustrated schematically in FIG. Otherwise, the exemplary embodiment according to FIG. 6 corresponds to the exemplary embodiment described in connection with FIG. 1.
    Figures 7 and 8 are schematic representations of a plan view from below of the cover 45 in the open position I (Figure 7) and the cover position II (Figure 8). The cover 45 is designed in the manner of a panel, the individual panel segments at least partially exposing the coverable opening 29 in the open position I and essentially completely closing it in the covering position II, whereby smaller gaps or openings can be present. Portable devices 20 can thus, analogously to the exemplary embodiment according to FIG. 1, with the cover 45 in the open position I, be arranged from above over the excrement 21 so that it is located in the comminution chamber 27 (FIG. 6). If the subsurface 22 is not sealed, the cover 45 can remain in the open position I and the electrical switch 32 can be actuated and the excrement 21 can be crushed on the spot in order to seep into the subsurface 22. If the subsurface 22 is a sealed surface, the cover 45 can be moved into the cover position II so that the excrement 21 is initially taken up in the shredding chamber 27 for removal and can be deposited and shredded at a suitable location, analogous to that in connection with FIG Design according to Figures 2 to 5 was explained.
    The exemplary embodiments described above can be combined with one another. In each exemplary embodiment of the portable device 20, a modular structure can be implemented, as is illustrated schematically in FIG. This makes it possible, for example, to equip the device 20 with a comminution chamber 27 with and without a cover, depending on the currently desired use on unsealed or sealed surfaces. In all embodiments, the connecting part 35 can be telescopic.
    In the exemplary embodiments, the liquid nozzle 25 can be arranged so that it can rotate about an axis, as is shown schematically in FIG. 6 by way of example. The rotation of the liquid nozzle 25 can be generated by the liquid flow. Additionally or alternatively, the liquid nozzle 25 or the pump 24 and / or the motor-pump unit 24, 30 can be set up in such a way that the at least one liquid jet 33 emerges in a pulsating manner. In order to generate this pulsation, a pulsation unit can alternatively also be arranged in the fluid connection between the pump 24 and the liquid nozzle 25.
    In all of the exemplary embodiments explained above, the wall 28 and / or the cover 45 is formed from solid, rigid parts, for example plastic, aluminum or other materials. In FIGS. 11 and 12, a modified exemplary embodiment is shown in a highly schematic manner, in which the wall 28 can be stretched in the manner of an umbrella. FIG. 11 shows the unclamped state in which the portable device 20 can be stored or transported. FIG. 12 shows the expanded state in order to make the portable device 20 ready for operation, the expanded wall 28 then enclosing the comminution chamber 27. In this embodiment, the wall 28 is made of a stretchable textile material that is in particular impermeable to water. Materials from which umbrellas are made come into consideration, for example. In the expanded state, the wall 28 has approximately the shape as illustrated in FIGS. 1, 9 and 10. The coverable opening 29 is located on the underside.
    The invention relates to a portable device 20 for comminuting or liquefying feces, in particular animal feces. The portable device 20 has a handle 33 and, in the longitudinal direction L, a comminution chamber 27 at a distance from the handle 33, which is at least partially delimited by a wall 28. At one point, the wall 28 delimits a coverable opening 29 through which the comminution chamber 27 is open to the outside. The device also has a liquid nozzle 25 with a nozzle opening 26 which is directed into the crushing chamber 27. A drivable pump 24 is fluidly connected between a liquid container 23 and the liquid nozzle 25 in order to convey liquid from the liquid container to the liquid nozzle 25. As a result, at least one liquid jet F emerges from the liquid nozzle 25 in order to comminute excrement 21 and mix it with the liquid which is located in the comminution chamber 27.
