    The invention relates to a device for disinfecting with a Zerstäubungsäeinrichtung and a plurality of liquid containers for receiving the liquid to be atomized, the atomizer is connected in use with one of the plurality of Flüssigkeitsbehältem to be supplied from the liquid container with the liquid to be atomized.
    For the purpose of killing dangerous particles such as viruses, spores, bacteria etc. in rooms or for room and surface disinfection, the liquid vapor or mist emitted by such a known atomizing device is allowed to act in a room or environment. It is e.g. dispersing a liquid suitable for disinfection in the form of droplets as aerosol uniformly in the ambient air, whereby it can be dispersed in the air and on surfaces e.g. meets infectious particles, which are rendered harmless by the disinfecting action of the liquid.
    Since disinfection devices of this type are placed in different rooms when used, they are usually easily moved or shipped. As a reservoir for the liquid to be atomized serves a liquid container, usually in the form of a canister, which is connected to the atomizing device. As soon as the liquid container is empty, it is replaced by a full one. Proper use of the disinfecting device presupposes that the liquid used is actually intended for this purpose. By unwanted manipulations, such as diluting the disinfecting liquid with water or replacing it with another liquid, the result of the application can thus be falsified. It is therefore in the interest of both the manufacturer and the user that no unauthorized changes to the contents of the liquid container are made, which could not be checked so far. -1 -
    The object of the invention is therefore to provide a disinfecting device of the type mentioned, which allows monitoring and control of the liquid to be atomized.
    According to the invention this is achieved in that an RFID unit is provided, wherein the plurality of liquid containers is each equipped with an associated RFID transponder, so that the RFID transponder of each connected liquid container with the RFID unit is connectable and data between the RFID Unit and the RFID transponder are transferable, and that a control unit is provided, via which the atomizing device is controllable on the basis of the transmitted data.
    With the aid of a known RFID (Radio Frequency Identification) unit, data corresponding to a specific liquid container can be read out and corresponding information about the liquid, concentration, container level, manufacturer information etc. can be obtained, which is helpful for the application of the disinfection device are. In this way, each user or user of the disinfection device can ensure that the basis for the disinfection of a room or an object, namely the disinfecting liquid to be atomized, is actually supplied in the correct composition to the atomizing device. According to the invention, liquid containers are provided which are each equipped with RFID transponders. There are only those
    Liquid container for disinfection, which can be identified by the RFID unit and their content can thus be clearly determined. Unless an approved liquid container is connected to the device according to the invention, a dedicated control unit blocks the startup of the atomizer, so that the use of a non-identifiable liquid is prevented. -2- • *
    According to a further embodiment of the invention, a bidirectional communication connection can be formed between the RFID unit and the RFID transponder.
    The liquid containers may also be reusable by sending empty containers back to the filler and refilling them. The memory content of the RFID transponder attached to the container is adjusted during refilling according to the new filling. In order to exclude changes in the container contents during transport, appropriate deception-proof closure mechanisms can be provided.
    Once a liquid container has been identified and opened by the user, the disinfecting device according to the invention could still be used during the use. always an undesirable change in the container contents happen. For this reason, according to a further embodiment of the device according to the invention, a weighing unit for measuring the instantaneous weight of the liquid container can be provided.
    Since the instantaneous weight of the liquid container steadily decreases during operation of the device according to the invention, the continuous weight measurement can be used to monitor a weight decrease of the liquid container corresponding to the extent of the liquid reaching the atomization. This can be done either by comparison with the recorded operating times of the device according to the invention or with a liquid flow meter or other type of determination of the amount of liquid dispensed.
    Should liquid have been improperly added to the liquid container, a central controller could signal the sudden increase in container weight and cause the sputtering device to become blocked. -3-
    The current weight measurement can be carried out according to a further embodiment by forming a support surface for the liquid container connected in use, wherein the support surface includes an electronic balance.
    According to a development of the device according to the invention, the electronic balance may comprise a strain gauge, via which the instantaneous weight of the liquid container can be measured.
    However, the weight measurement in the context of the invention can also be carried out differently, for example by the weighing unit comprising a nacelle for receiving the liquid container which is suspended from a weighing cell of the device according to the invention.
    Depending on the type, the RFID tags operate at 125-134 kHz in the longwave, 13.56 MHz shortwave, UHF at 865-869 MHz (European frequencies) and 950 MHz (US and Asian frequency bands) or the SHF at 2.45 GHz and 5.8 GHz. The shared frequencies for LF and UHF tags vary regionally for Asia, Europe and America and are coordinated by the ITU.
    Since the content in the liquid container in different
    Frequency ranges caused a strong absorption of the electromagnetic waves used for RFID traffic, it has been found to be particularly preferred that the RFID unit and the RFID transponder in the frequency range of 13.56 MHz work. However, other frequency ranges can also be used.
    Depending on the intended use, the RFID transponders mounted on the liquid containers can store different data.
    According to a further exemplary embodiment of the invention, the RFID transponders may preferably store at least one of the following data contents.
    And / or include: manufacturer ID, product ID, container ID, expiration date, initial weight, static checksum, current weight, overflow count, dynamic total checksum.
    On the one hand, these data make it possible to identify and, on the other hand, also to further administer the content of the contents of the container, should a transfer to or filling by other containers be permitted.
    To ensure trouble-free communication between the RFID unit and the attached to the liquid container RFID transponder, the smallest possible or at least a well-defined distance between the RFID unit and the RFID transponder for transmitting and receiving the electromagnetic waves should be maintained.
    According to a further embodiment of the invention, therefore, a positioning device can be provided, which determines the connection of the liquid container to the atomization device in a predetermined spatial position and orientation. Such positioning devices can be designed in the context of the invention in a known manner, so that the container is set in a well-defined position relative to the device according to the invention.
    On the other hand, the liquid container may also be connected without said positioning measures, but larger transmission energy would then have to be applied or larger antennas would have to be used for secure RFID transmission.
    According to a further embodiment of the invention, a holding device for one of the plurality of liquid containers may be provided which comprises the support surface, a rear wall and two adjoining the rear wall and the support surface side walls, which adapted to the dimensions -5- ί · the liquid container receptacle form, in which the liquid container with a fixed orientation is replaceable.
    The holder device designed in this way allows a rotationally secure placement of the liquid container. By providing additional latching elements od. Like. The liquid container can be kept in a clearly defined position.
    Furthermore, the rear wall of the Aufnahmeehaiterung have a recess in the region of the RFID unit is arranged.
    According to a further embodiment of the invention, the support surface may comprise a weighing surface of the electronic balance, wherein the electronic balance is supported against a arranged in the housing frame bottom element. As a result, the electronic balance can be easily integrated into the holding device for the liquid container.
    The invention will be explained in detail with reference to the embodiment shown in the drawings. It shows

    1 to 4 show various views of a housing frame 1, which includes parts of an embodiment of the disinfecting device according to the invention, comprising a sputtering or misting device, not shown, which atomises in use a liquid or sprayed, and to the environment in the form of a Liquids containing liquid droplets releases, for example To decontaminate or sanitize a room by destroying suspended or surface-adhering particles in the air so that they are rendered ineffective to humans or animals, preventing them from infesting cells and causing their harmful effects. But it can also be e.g. Food or computer keyboards are released from dangerous germs or other particles in which they are exposed to the output from the atomizing device according to the invention liquid mist or vapor.
    During operation, the atomizing device discharges a steady stream of liquid droplets, which distribute accordingly and exert their disinfecting effect. As the liquid to be atomized, e.g. Hydrogen peroxide are used, but it can be atomized other approved by the manufacturer liquids or mixtures of liquids or pure water, which has no disinfecting effect.
    The housing frame 1 divides the housing by vertical and horizontal struts and a wall in two areas 2, 3, of which the area 2 to -7-
    Recording of the atomizer, not shown, is used. At the top of the area 3, a desk with a display 9 and a keypad 13 is formed, via which the control of the device according to the invention can be carried out. For easier transport of the frame 1 rollers 10 are provided on its underside.
    The area 3 includes a cavity for receiving a liquid container, which is not dargesteilt in Fig.1 to 4. From this liquid container, the atomizing device is supplied with the liquid to be atomized and then atomized. For this purpose, the liquid container is detachably connected to the atomizing device and can be replaced at vacancy with a full liquid container. For this reason, a multiplicity of liquid containers, at least two liquid containers, are present with which the inventive disinfection apparatus can be operated with liquid to be atomized.
    According to the invention, an RFID unit 7 (FIG. 5) is provided and the plurality of liquid containers are each equipped with an associated RFID transponder (not shown), so that the RFID transponder of the respectively attached liquid container is connected to the RFID unit 7 via electromagnetic coupling is connectable and data between the RFID unit 7 and the RFID transponder can be transmitted.
    The RFID unit 7 and the RFID transponders preferably operate in the frequency range of 13.56 MHz. However, other frequency ranges may also be used within the scope of the invention.
    As an RFID transponder, an already known transponder, which is commercially available, find use and be mounted on the liquid container.
    A control unit, not shown, processes the data read in by the RFID unit 7 and controls the atomizing device. Mainly -8-
    Data can be read out via the RFID unit 7, but the RFID transponder can also be described with data via the RFID unit 7. The data traffic can thus also be bidirectional.
    In this way, specific data for each of the plurality of liquid containers may be stored on the associated RFID transponder, which are important for the disinfection or the atomization process and at the same time allow a clear assignment of the container contents and the bottler to the respective Flüssigkeitsbehä Iter.
    The RFID unit 7 consists e.g. from a transmitter / receiver, of which e.g. an electromagnetic signal is emitted via an antenna that can be received by the RFID transponder. As soon as the RFID transponder is identified, the data exchange can begin, wherein the RFID transponder can actively send data or else can be passive, so that it can be recognized by the RFID unit 7.
    In this way, it is ensured that the suitable liquid is supplied from the liquid container to the atomization process, whereby an abusive use of the disinfection device according to the invention can be prevented. Depending on the existing display, certain data may be displayed to the user and the user may decide for himself whether to reject or use a particular liquid. Likewise, this selection process can also be controlled automatically.
    The RFID unit 7 can be equipped with a relatively small internal antenna, resulting in a short range. Accordingly, the distance between the RFID unit 7 and the RFID transponder must be kept small or constant. The RFID transponder is therefore preferably always attached to the same location of the liquid container. Alternatively, a larger external antenna or a more powerful RFID unit can be provided, which can also detect RFID transponders in a larger distance range. The -9- • * • «
    Liquid container then does not have to be aligned exactly to carry out the data exchange.
    The RFID transponder may e.g. The following data contains or may be requested for the following data.
    Producer ID: The producer ID contains e.g. a fixed portion that identifies the application, e.g. Disinfection and a dynamic proportion that identifies the producer of the product.
    Product ID: Above the product ID may be different
    Liquid compositions or concentrations for disinfection, e.g. DCFill 4%, DCFill 16% etc., so that it can not be confused with the liquid container.
    Container ID: is a unique serial number given by the manufacturer.
    Expiration Date: As the disinfectant fluids lose their effect over time, an expiration date is stored which may be associated with a lock on the respective fluid reservoir to prevent the ineffective fluid from being used.
    Initial Weight: The initial weight indicates the weight that exists at the time the respective liquid container is connected to the atomization unit. As a proper
    Use of the liquid container is always associated with a steady weight loss, this results in a corresponding control option.
    Sum of static data: Can be used e.g. be specified encrypted. -10- V «· · ·« · m · Λ t · »• · · · • · • · • ·« · «·«
    Present Weight: Indicates the calculated weight that the container should have due to its use by the disinfecting device of the invention until a certain time.
    Decanting Count: Once additional liquid has been emptied into a container with authorization, a count, e.g. Weight or volume, increased accordingly. The further calculations then take place on the basis of this count.
    Checksum Dynamic Data: Calculated by taking into account changing data that is constantly detected, and can e.g. be stored encrypted.
    In a simplified form, the invention could also be carried out via a barcode system. Instead of the RFID tag, a bar code identifier, in particular a 2D code, is used, which contains the necessary data. It is not necessary to write back the data to the 2D code so that only limited functionality can be achieved.
    The Zerstäubungseinrichtüng according to the invention is controlled on the basis of the data transmitted between the RFID unit 7 and the respective RFID Trahsponder. One possible form of control involves monitoring the current weight of the fluid container.
    For measuring the instantaneous weight of the liquid container, a weighing unit 65 shown in FIGS. 1 to 14 is provided, which enables a further processing of the weight data thus measured. 10 to 14 show the weighing unit 65 which has support legs 40 on its underside, with a liquid container 90 arranged thereon. For filling or emptying the liquid container 90, a closure 91 is formed, via which the liquid container 90 can be connected to the atomizing device , The Flüssigkeltsbehälter 90 is further secured against dislocation on the weighing unit 65 by a Gurtverschluss 93; -11 - • »
    The device according to the invention has a support surface 21 (FIGS. 8, 9) for the liquid container 90 (FIG. 12) connected in use, wherein the support surface 21 includes an electronic balance 71 which is part of the weighing unit 65 and a strain gauge, not shown in FIG a measuring unit 70, via which the instantaneous weight of the liquid container 90 is measured. For the weight detection, other measuring principles can also be used within the scope of the invention.
    As already mentioned, for a data transfer between the RFID unit 7 and the RFID transponder that is as undisturbed as possible, a specific fixed orientation of the liquid container 90 with the RFID transponder arranged at a specific location of the liquid container 90 should be aimed at with respect to the RFID unit 7.
    For this purpose, a positioning device is provided, which determines the connection of the liquid container to the atomization device in a predetermined spatial position and orientation. The embodiment of the positioning device may be made by known means such as positive engagement of the container in a holder or e.g. done by suitable latching noses.
    In the disinfection device according to the invention, a holding device for the liquid container 90 is provided, which comprises the support surface 21, a rear wall 22 and two adjoining the rear wall 22 and the Aüflagefläche 21 side walls 23, 24, one to the dimensions of
    Liquid container 90 adapted receptacle, in which the
    Liquid container 90 can be replaced with a fixed orientation, wherein the rear wall 22 has a recess 26 in the region of the RFID unit 7 is arranged.
    The support surface 21 has a weighing surface 28 of the electronic balance 71, via which the determination of the instantaneous weight of the liquid container -12- '' '··' * ·· * »tt ······ Φ · * · · t» «··················································································································································· The electronic balance 71 is supported against a bottom element 30 arranged in the housing frame 1, which is held in the frame 1 (FIG. 4). During operation of the disinfecting device according to the invention, the RFID data can be used in various ways. The data can also be stored for statistical and control purposes.
    The control unit reads the type of liquid from the RFID transponder and monitors whether it complies with the prescribed.
    Furthermore, the control unit monitors the stored in the RFID transponder expiration date of the liquid and locks the atomizer when exceeding the expiration date.
    The control unit also queries the current weight of the liquid container continuously and transmits it to the RFID transponder and stores it in this.
    The control unit monitors that the polled current weight of the liquid container is equal to or less than the weight stored in the RFID transponder, and if the interrogated weight is greater than the weight stored in the RFID transponder, it blocks the atomizer.
    The control unit increases the weight of a collecting liquid container stored in the RFID transponder into which the contents of one or more liquid containers to be emptied are emptied by the weight of the liquid containers to be emptied. The control unit sets the expiration date to the oldest of all expiration dates of the liquid containers involved in the reloading process. -13- •••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••
    When changing a liquid container, the transponder of a new liquid container enters the read / write area of the RFID unit 7. In this case, several checks are performed, such as whether the liquid contained in the new liquid container is suitable for the selected purpose. Further, e.g. Check the expiration date of the liquid to be atomized. An appropriate warning in the event of expiration can be displayed to the user.
    As soon as a new liquid container 90 has been inserted into the holding device, the weight stored in the RFID transponder can be compared with the current weight and corresponding commands of the controller can be generated, which can also be displayed on the display 9. If the user is about to remove a liquid container rejected by the controller and replace it with a suitable container, he will be informed. During operation, it is checked if there is an ongoing weight loss. If the weight increases, the liquid container in question is rejected because of contamination by added liquid and the
    Atomizer subjected to a lock.
    If a liquid container by dumping from another
    Liquid container is to be nachgefüilt and this is allowed by the user, the expiration date of the oldest liquid must be stored as the new expiration date of the resulting mixture. It can be the weight of the liquid container; is refilled from the first determined and stored on the weighing unit and then introduced the liquid container to be filled in the weighing unit and compared the calculated new weight with the adjusting by the refilling current weight and the new expiration date are stored. -14-
