    The new dispenser for micro-spray backpacks is a device of reusable nature that has at least one cartridge that allows to contain at least one agrochemical element or another type of concentrate that wants to be dispersed separately from the dilution medium, having means to perform this one in the same moment in which its application is needed. Avoiding both the risks of poisoning during conventional dilution, as well as the spills or spills produced in the cleaning of the deposits of the current backpacks. The device contemplates the regulation in the concentration of the mixture, as well as the change of the cartridges without the discharge of the solvent contained in the tank of the backpack. The cartridge prevents the oxidation of the concentrate that is intended to be applied since it is isolated, reducing economic and environmental costs. The device is intended for the agricultural and industrial sectors. (Machine-translation by Google Translate, not legally binding)

    DESCRIPTION
    New micro spray backpack with independent mixing system by extralble cartridge.
    Technology Sector
    The present invention is comprised within the agricultural and industrial sectors, especially intended for manufacturers of liquid agent spray systems.
    Background of the invention
    At present there are different types of devices aimed at spraying liquid agents, these devices are used for tasks such as the dispersion of fertilizers or pesticides in the agricultural environment or other applications in the industrial environment. Within these devices, systems for manual use by the person performing the treatment are known whose sprayers generally referred to as spray or spray backpacks basically comprise a tank carrying the liquid to be sprayed; This liquid is constituted by a concentrated agent usually diluted in water. The deposit is pressurized interchangeably by a manual system based on the action of a lever system and a plunger or, assisted by a small, usually electromechanical, compressor group. The agent to be sprayed dispersed in the water is conducted thanks to this pressure generated by the compressed air through a hose to a spray nozzle located at the end of a hollow tube known as a lance. There are alternatives to this provision consisting of arranging the aspiration and pumping means independent of the tank and next to the lance as described in the patent ES 2019773 of the applicant Enrique Genoves based on the use of motor actuation means, which differs from the one recommended as it can appreciate.
    The state of the art thus collects different solutions aimed at improving the pressurization of the tank or deposit such as US5984199A Backpack sprayer with an expandable accumulator chamber and US patent US 8672364 82 Quick disconnect device for connecting a sprayer s tank to a portable pump assembly, as! as others aimed at automating the process including electrical systems such as CN200987334Y Backpack electric sprayer.
    In these patents, great differences can be seen both in the pressurization system of the mixture and in the final function, since for example US5984199A Backpack sprayer with an expandable accumulator chamber consists of a container as an elastomeric bag that improves pressure output of the mixture, but it is not an independent device that avoids mixing directly in the tank or the rest of the safety, volume control and hygiene characteristics that this patent recommends.
    The Backpack electric sprayer CN200987334Y patent presents an external electric pump that generates greater pressure for the mixture to exit but does not imply any novelty regarding the realization of the mixture outside the tank.

    The patent Sprayers for dispensing deterrent chemicals US5775543A, presents a container with the mixture already made and under pressure in which the deposit is made as a flexible bag.
    Devices such as the one recommended in the present invention are not known.
    Object of the invention
    Provide the agricultural and industrial sector with new microaspersion backpacks that present a separate dosing device to the mixing tank that minimizes the problems of environmental contamination, safety and health derived from the use of agrochemicals or other potentially dangerous or polluting substances, avoiding product escape, impact on operators and their environment.
    It has advantages of use such as the easy use of cartridges with the agent to disperse, a reduced weight, optimum dosage and easy handling.
    Versions are planned in which the use of biodegradable material cartridges is considered, which will allow once the product has been used up its recycling is simpler and more efficient.
    On the other hand, versions have also been considered that allow the cartridge to be refillable and reusable for greater use of the materials while allowing greater possibilities in the formulation of the components to be sprayed.
    In this way, the main objectives of the invention are focused on avoiding the contact with these potentially dangerous substances by the user, while at the same time it represents a considerable saving since the mixture is produced at the time of use, keeping the agent concentrated preserved in the cartridge and not diluted in the tank with the consequent problem of pouring the mixture that has not been used and cleaning the tank.
    Description of the invention
    There are many problems arising from the manipulation of the agents to be sprayed in a backpack, whether these are pesticides or fertilizers, for example, or others oriented to industrial applications. On the other hand, once these substances have dissolved in the tank, the content must be used in a short time, it is usual that not all the prepared product is consumed, this generates serious environmental problems given the difficulty of recovery that these by-products generally present . The recommended invention solves these problems, allowing the mixing of the substances to be dispersed with the solvent at the time of the application, consuming only the amount required in an application, for this the backpack has means to store the substances to Disperse separated from the tank by independent cartridges and means for proper dosing of these substances.
    The micro sprinkling backpack with independent mixing system by means of a recommended extralble cartridge has a cartridge system with its corresponding complementary cartridge receiver housed in the backpack, these cartridges can be reusable in nature and allow the fluid to be controlled in a safe and secure way that we want to disperse, thus avoiding manipulation by the operator of

    Potentially harmful or dangerous substances for both this and the environment, also preventing damage to the equipment. The cartridge of preferably cylindrical nature contains in its lower base conventional connection means such as an interconnection valve with the cartridge receiver that allows the passage of the fluid when it is connected and that has means to prevent any spillage when the cartridge is removed, these means are materialized by a perforable membrane made of an elastomeric material, whose elasticity allows the closure and sealing of this temporary opening after the connection needle that the cartridge receiver has in the backpack is removed; versions are planned in which the interconnection of the cartridge and the receiver thereof is carried out by means of a conventional quick coupling provided with at least one non-return valve, this version is especially useful when the fluid to be dispersed has a high viscosity, as it is provided its flow with a system that allows a pitch diameter greater than the needle system. The upper cover of the cartridge forms a plunger that slides into the lateral surface of revolution of this to allow the emptying of the cartridge, and presents means to guarantee its tightness such as the use of conventional toric joints or the tightening adjustment. Versions are planned in which the spraypacks have a housing for cartridges with means to generate pressure on the cartridge, such as a piston driven by a gas or elastic spring whose stored energy is transmitted to the cartridge of the described cartridge and whose object is maintain a uniform pressure that facilitates the exit of the fluid, especially in the case that the cartridge contains high viscosity fluids.
    Versions are contemplated in which the cartridge that stores the substance to be dispersed is deformed when its volume varies, since its body is made with a plastic of high elasticity and low thickness, so that with the suction of the fluid it can reduce its volume When its walls are deformed, other alternatives are also applicable, such as the realization of the cartridge in an elastic material that contains the substance to be dispersed compressed, the pressure stored in the cartridge is transmitted to the fluid when the mixer valve is open.
    The cartridge receiver has at least one interconnection system with its complementary cartridge, the receiver can, when it houses several cartridges, have means to be able to select and dose each of them independently, allowing to mix substances at the time of its application, avoiding inconveniences such as the degradation of some mixtures over time, and correcting their possible mixing at the discretion of the person using the backpack. This is especially useful as it allows different treatments or applications to be carried out without the need to perform, as traditionally, a new cleaning and preparation of the spray tank.
    These selection and dosing means are carried out by having the cartridge receiver have at least one opening and regulation valve for each of the installed cartridges, the output of these opening and regulation valves converge in a common manifold, where the mixing and distribution of the substances to be dispersed, the exit of this collector flows into the water drag line of the tank prior to the lance, being able to be mixed with the water of the tank by means of the venturi effect or optionally supported with a complementary pump.

    The cleaning of the collector occurs once all the valves of the cartridges are closed; when the pressure system of the backpack is activated, the passage of water or solvent to the outside will produce this cleaning.
    Versions are planned in which the collector that collects the different substances to be sprayed has a conventional static mixer to facilitate the correct integration of the components with the solvent, in the case that the fluids have very different viscosities or mixed flow flows very small. Other versions are also planned in which this mixer is dynamic.

    Description of a preferred embodiment
    A preferred embodiment is cited by way of example, being independent of the object of the invention the materials used in the manufacture of the new micro-spray backpack with an independent mixing system by means of an extrafole cartridge object of the present specification and all the accessory details that may occur, as long as they do not affect their essentiality.
    The backpack has means for housing in isolation from the solvent in the tank (3) Figure 1, the agents to be dispersed, these means comprise at least one cartridge (11) housing the concentrated agent, for example a pesticide or any other substance. The cartridges preferably have a cylindrical nature and comprise, at their lower base, an interconnection valve with the redproco cartridge (10) receiver that allows the passage of the fluid when they are interconnected and which has means to prevent any spillage when the cartridge is extracted, these means are materialized by a perforable membrane
    (13) made of an elastomeric material, whose elasticity allows the closure and sealing of this temporary opening caused by the connecting needle (14) of the cartridge receiver. The upper cover of the cartridge (12) forms a plunger that slides inside the lateral surface of revolution of this and presents means to guarantee its tightness such as the use of conventional toric joints, this displacement of the embolus allows the emptying of the cartridge. It has an elastic spring (9) that puts pressure on the top cover to facilitate the pouring of the substance to be dispersed.
    The cartridge receiver (10) comprises at least one conventional regulation valve (17) per cartridge, which regulates the fluid entering the manifold (18) where it is mixed with the water or solvent from the tank that penetrates pressurized through its entry (19) into the static mixer (21) located inside the collector, whose function is to receive and mix the substances to be applied through fixed structures that produce variations within the fluid contributing to its integration with the solvent, then the mixture leaves the collector through the outlet point (20) to the hose (2) and its corresponding lance (1) ready to be dispersed.
    For a better understanding of the invention its use is described, in this way to make an application of a product such as a fertilizer, the user introduces at least one cartridge (11) with the concentrate inside a complementary cavity to house the cartridges (7 ), this cavity may have a cover (8) to guarantee cartridge retention. The lower end of this cavity is coincident with at least one cartridge receiver (10) in such a way that when a cartridge is inserted, this thanks to its connection, through the membrane (13) and needle cooperation
    (14), it is allowed to pour into the collector (18) described. This described configuration allows the simultaneous use of several cartridges offering the possibility of making different mixtures depending on the needs of the person applying the treatment.
    The pressurization of the fluid contained in the tank is carried out by conventional means such as the actuation by the user of a set of levers (4) operating on the pressure group of the backpack (5) located in the tank. The tank has the corresponding filling and pouring lid (6).
