[0063] The spray-type intelligent air purification device 100 according to an embodiment of the present invention will be described in detail below with reference to the accompanying drawings.

[0064] Reference Figures 1 to 4 As shown, the spray-type intelligent air purification device 100 provided according to an embodiment of the present invention includes a medicine container 10, a liquid pump 20, a radio frequency identifier 30 and a control device 40.

[0065] Specifically, the medicine container can be a medicine barrel or a medicine bottle, etc., so as to facilitate replacement. The medicine container 10 is used to hold a medicine liquid containing an air purifier, and the medicine container 10 has an electronic tag 101. The electronic tag 101 can be a radio frequency tag, which can be built into the medicine container 10, or fixed on the surface of the medicine container 10 in other ways. The electronic tag 101 has label information, and the label information at least includes the medicine liquid information and the manufacturer information, such as the name, weight, production time, manufacturer, etc. of the medicine liquid. The air purifier in the medicine liquid can be a deodorizing composition that can react with harmful chemicals in the air.

[0066] The liquid inlet of the liquid pump 20 is connected to the medicine container 10, and the liquid outlet of the liquid pump 20 is suitable for connecting to an external spray device 90, so as to spray the atomized liquid medicine to the environment to be purified through the spray device 90. That is, in a specific application, the liquid pump 20 in the spray-type intelligent air purification device 100 needs to be connected to the external spray device 90, and the liquid medicine in the medicine container 10 is pumped into the spray device 90 through the liquid pump 20, and then sprayed out through the spray device 90. In this way, the atomized liquid medicine can be sprayed to the environment to be purified through the spray device 90, and the atomized liquid medicine reacts with harmful molecules in the air in the environment to be purified, removes harmful substances in the air, and achieves the purpose of purifying the air.

[0067] The RFID 30 is used to read the label information of the electronic tag 101. In actual application scenarios, the RFID 30 can be installed at a position that is convenient for reading the electronic tag 101 on the medicine container 10. For example, the medicine container 10 has a fixed placement position, and the RFID 30 can be configured at or near the placement position, so that when the medicine container 10 is placed at the placement position, the RFID 30 can automatically identify and obtain the label information of the electronic tag 101 on the medicine container 10.

[0068] The control device 40 is connected to the liquid pump 20 and the RFID 30 to control the liquid pump 20 and to perform anti-counterfeiting verification on the label information, wherein the label information at least includes the liquid medicine information and the manufacturer information. In other words, the control device 40 can control the switch of the liquid pump 20 to realize the start and stop control of the spray function. In addition, the control device 40 can also perform anti-counterfeiting verification on the label information, such as verifying the manufacturer information to determine the source of the liquid medicine.

[0069] According to the spray-type intelligent air purification device 100 provided by the embodiment of the present invention, the liquid medicine in the medicine container 10 is pumped into the spray device 90 through the liquid pump 20, and the spray device 90 is used to spray the atomized liquid medicine to the environment to be purified. Since the liquid medicine directly reacts with the odor molecules in the air, effective air purification is achieved. In addition, the surface area of ​​the atomized liquid medicine is increased, and it is more capable of capturing the odor molecules so as to react quickly, and the purification effect is better. In addition, there is an electronic tag 101 on the medicine container when it leaves the factory. The radio frequency identifier 30 can read the label information of the electronic tag 101, and the control device 40 can perform anti-counterfeiting verification on the label information to ensure that the medicine container comes from the target manufacturer, ensure the source, safety and effectiveness of the liquid medicine, and prevent the abnormal source of the liquid medicine, which makes it difficult to ensure its quality and safety, etc., and cause harm to the public environment.

[0070] In some embodiments of the present invention, the control device 40 is further configured to perform an early warning action when the label information is not read or the label information anti-counterfeiting verification fails. Preferably, the early warning action is to limit the start of the pressure pump to stop the spray function of the spray device 90.

[0071] That is to say, on the one hand, when the RFID 30 does not obtain the tag information of the electronic tag 101, the control device 40 can perform an early warning action, such as limiting the start of the pressure pump. In this way, when the medicine container is removed from the placement position or replaced with a medicine container of another manufacturer, the pressure pump can be prohibited from starting, thereby locking the machine. On the other hand, when the tag information obtained by the RFID 30 fails to pass the verification, for example, the manufacturer in the tag information is inconsistent with the target manufacturer, the control device 40 can also perform an early warning action, such as limiting the start of the pressure pump, so that the machine can also be locked.

[0072] In this embodiment, through the above-mentioned early warning action, the machine is locked when there is no medicine container 10, or when the medicine container 10 is placed but the medicine is of unknown source, or when the medicine used by the user end is not from the target manufacturer. In this way, it can ensure that the user end uses the medicine of the target manufacturer, guarantee the purification effect and safety, and also protect the interests of the manufacturer.

[0073] It is understandable that the warning action may also include other warning methods, such as warning prompts, which may be voice, text and other prompts, so that both the user end and the manufacturer can be aware of the above situation.

[0074] Reference Figures 2 to 4 As shown, in some embodiments of the present invention, a weighing device 50 is further included. The weighing device 50 is suitable for carrying the medicine container 10 to detect the weight of the medicine liquid in the medicine container 10 in real time.

[0075] The control device 40 is also used to perform an early warning action when the weight of the medicine liquid in the medicine container 10 changes abnormally, and / or when the weight of the medicine liquid is equal to or lower than a predetermined threshold, mark the electronic tag 101 as an invalid state, and the control device 40 performs an early warning action in the invalid state.

[0076] That is to say, the weighing device 50 can be used to detect the weight of the liquid medicine in the medicine container 10 in real time, and then monitor the changes of the liquid medicine in the medicine container 10. On the one hand, when the weight of the liquid medicine changes abnormally, the control device 40 performs an early warning action, such as the above-mentioned limiting liquid pump 20 is started, and then the device is locked. Preferably, the abnormal change can be that the weight of the liquid medicine increases instead of decreases. Since the weight of the liquid medicine gradually decreases over time during normal use, when adding liquid medicine or other liquids to the medicine container 10, the problem of the liquid increasing instead of decreasing may occur. This situation may be that the user adds liquid to the medicine container 10 by himself, and adding liquid by himself may cause the liquid medicine to be diluted or even mixed with other liquids, resulting in problems such as reduced performance or failure of the liquid medicine. By monitoring the weight change of the liquid medicine, the device can be locked when the liquid medicine changes abnormally, thereby preventing the user from performing illegal operations by himself, and further improving the anti-counterfeiting effect.

[0077] On the other hand, a predetermined threshold can be set. When it is monitored that the weight of the medicine liquid in the medicine container 10 is equal to or lower than the preset threshold, for example, the weight of the medicine liquid drops to 0, or is lower than a lower value, it is determined that the medicine liquid in the medicine container 10 is exhausted. When the medicine liquid is exhausted, the control device 40 marks the electronic tag 101 as an invalid state. In the invalid state, an early warning action is performed, such as restricting the start of the liquid pump 20, that is, locking the machine. In this way, it can prevent the user from adding medicine liquid to the medicine container and reusing it after recycling the medicine container by themselves, further ensuring that the medicine liquid can only come from the target manufacturer and the medicine container cannot be reused after a one-time use, thereby achieving an extremely effective anti-counterfeiting effect.

[0078] Reference Figure 1 to Figure 2 As shown, in one embodiment of the present invention, a cabinet 80 and a cabinet door 81 are further included. The medicine container 10, the liquid pump 20, and the control device 40 are arranged in the cabinet 80, and the cabinet door 81 is movably connected to the cabinet 80 to open or close the cabinet door 81. The radio frequency identifier 30 is installed on the cabinet door 81. When the cabinet door 81 is closed, the electronic tag 101 on the medicine container 10 is within the recognition range of the radio frequency identifier 30 to obtain the tag information of the electronic tag 101.

[0079] In this embodiment, the medicine container 10, the liquid pump 20, the control device 40, etc. are installed in the cabinet 80 to form an integral device, which is convenient for installation. In addition, the radio frequency identifier 30 is installed on the cabinet door 81, for example, the radio frequency identifier 30 is installed on the inner surface of the cabinet door 81, and the electronic tag 101 can be installed on the side of the medicine container 10. In this way, after the cabinet door 81 is opened and the medicine container is placed in the corresponding placement position, when the cabinet door 81 is closed, the radio frequency identifier 30 on the cabinet door 81 is opposite to the electronic tag 101, and the electronic tag 101 on the medicine container can be identified, and then the label information of the electronic tag 101 can be read. In this way, it is convenient to read the information of the electronic tag 101. And when the cabinet door 81 is opened, the radio frequency identifier 30 is far away from the medicine container and cannot read the label information of the electronic tag 101, and the early warning action is immediately executed. In this way, it can be ensured that the device can operate reliably without external interference. Once an interference action such as opening the door occurs, early warning protection is immediately performed to improve the reliability and safety of the device.

[0080] Reference Figure 2 and Figure 4 As shown, in some embodiments of the present invention, a door lock 60 is further included, and the door lock 60 is arranged between the cabinet door 81 and the cabinet 80 to lock the cabinet door 81. The door lock can be a manual door lock or an electronic door lock. When it is an electronic door lock, the control device 40 is connected to the electronic door lock 60 to receive instructions from the remote monitoring terminal 200 and control the switch of the electronic door lock 60.

[0081] That is to say, in this embodiment, the cabinet door 81 and the cabinet 80 are locked by the electronic door lock 60. For example, the electronic door lock 60 is set on the cabinet door 81, and the cabinet door 81 is automatically locked when it is closed. In addition, the control device 40 can communicate with the remote monitoring terminal 200, receive instructions from the remote monitoring terminal 200, and realize the switch control of the electronic door lock 60. The remote control terminal can be a cloud platform or a mobile terminal, etc. In this way, permission configuration can be performed, and only authorized personnel can open the door, so as to facilitate effective management and prevent illegal operations, such as illegal replacement of liquid medicine, etc.

[0082] It is understandable that in other embodiments of the present invention, a manual door lock may be used between the cabinet door 81 and the cabinet 80 to facilitate manual locking or unlocking, and also to manage the equipment. The specific installation position of the door lock or manual door lock may be reasonably configured as needed, such as being set on the front surface of the cabinet door 81, or on the side of the cabinet 80, etc.

[0083] Reference Figure 4 As shown, in one embodiment of the present invention, the control device 40 includes a processor 401 and a wireless communication module 402 , and the processor 401 is connected to the liquid pump 20 , the radio frequency identifier 30 , and the weighing device 50 .

[0084] The wireless communication module 402 is connected to the processor 401 to upload the tag information, the weight of the medicine and the status of the electronic door lock 60 to the remote monitoring terminal 200, and receive instructions from the remote monitoring terminal 200 to control the liquid pump 20 and the electronic door lock 60. For example, the wireless communication module 402 can be, but is not limited to, a 4G / 5G module, a WIFI module, a NB-IOT module, a LORA module, etc.

[0085] That is, by establishing a wireless communication connection with the remote monitoring terminal 200 through the wireless communication module 402, local related information, such as the read label information, the weight of the monitored medicine, the status of the electronic door lock 60, etc., can be uploaded to the remote monitoring terminal 200, so as to realize remote monitoring and intelligent management. In addition, instructions can also be sent through the remote monitoring terminal 200. After the wireless communication module 402 receives the instruction, the processor 401 can control the intelligent air purification device according to the instruction, such as controlling the start or stop of the liquid pump 20, controlling the switch of the electronic door lock 60, etc., so as to realize remote control and management.

[0086] Reference Figure 4As shown, in one embodiment of the present invention, it also includes a power module 70 and an energy consumption metering module 71 , and the power module 70 is connected to the liquid pump 20 , the radio frequency identifier 30 , the control device 40 , the weighing device 50 and the electronic door lock 60 .

[0087] The energy consumption metering module 71 is connected to the power module 70 and the control device 40 to measure the energy consumption data of the spray-type intelligent air purification device 100. The control device 40 is also used to upload the energy consumption data to the remote monitoring terminal 200, and receive instructions from the remote monitoring terminal 200 to control the power module 70 switch.

[0088] That is, the energy consumption of the device can be uploaded to the remote monitoring terminal 200 through the energy consumption metering module 71, such as the power consumption of the device, to achieve energy consumption monitoring. In addition, the remote monitoring terminal 200 can send instructions to remotely control the power module 70 to facilitate power-off management of the device, especially when a fault occurs, it can be remotely processed by powering off or powering on and restarting.

[0089] Preferably, the spray-type intelligent air purification device 100 also includes a display screen 82, which is connected to the control device 40 to display relevant information and perform control interactions. The display screen 82 can be a touch display screen 82, so that it is convenient to obtain relevant information locally and perform interactive control through the display screen 82, such as controlling the opening of the electronic door lock 60 through the display screen 82, or controlling the start or stop of the liquid pump 20, etc.
