Description

Technical Field

[0001] This utility model belongs to the field of IoT hand hygiene technology, which combines IoT smart healthcare with liquid dispensing devices, and specifically relates to an automatic liquid dispensing monitoring and management system. Background Technology

[0002] A liquid dispenser, also known as a soap dispenser or dispensing device, is a device used to dispense liquid from a container. Currently, it is mainly used in hand hygiene, automatically dispensing soap during handwashing to avoid secondary contact with the soap bottle and subsequent contamination. It can be used in public restrooms, homes, hospitals, and other places, especially in hospitals where mandatory hand hygiene standards before surgery require its use. Currently, there is an existing patent: application number 202020859349, entitled "A Driving Mechanism and an Automatic Liquid Dispensing Device Using the Driving Mechanism," which discloses an automatic liquid dispensing device that ensures the liquid in the bottle does not come into contact with the internal structure of the device, and the liquid does not need to pass through the device, thus preventing secondary contamination.

[0003] However, currently, in hospitals, the standalone dispensing device only provides non-contact dispensing, and cannot statistically manage the amount of disinfectant used or the hand hygiene of medical staff using the dispensing device. Furthermore, the statistical management of hand hygiene compliance required by hospitals currently relies mainly on manual recording by patrol personnel, leading to insufficient data accuracy and the Hawthorne effect. Regarding the expiration date management of disinfectants, hospitals currently affix an open and expired date label upon use, but there are cases of continued use after the expiration date, and this wastes significant human resources in implementation and management. Additionally, there is no effective enforcement against illegal disinfectants. Utility Model Content

[0038] To more clearly illustrate the technical solutions in the embodiments of this utility model or the prior art, the present utility model will be briefly introduced below in conjunction with the accompanying drawings and descriptions of the embodiments or the prior art. Obviously, the following description of the structure of the accompanying drawings is only some embodiments of this utility model. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort. It should be noted that the description of these embodiments is used to help understand this utility model, but does not constitute a limitation on this utility model.

[0039] Example 1:

[0040] like Figure 1-3As shown, this embodiment provides an automatic liquid dispensing device, including a housing, a drive mechanism 1, a lever 13, and a PCB board 5. The housing includes an upper shell 2 and a lower shell 3, which together form a receiving cavity. The PCB board 5 and the drive mechanism 1 are disposed in the receiving cavity. The lower shell 3 is provided with a lever placement groove, and the lever 13 is disposed in the lever placement groove. The PCB board 5 is disposed above the lever 13.

[0041] In this embodiment, the drive mechanism 1 plays a driving role. It includes a drive motor, a transmission component, and a rotation counter. The drive motor drives the grating to rotate through the transmission component, thereby enabling the rotation counter to work. At the same time, it can drive the push lever 13 to move up and down, thereby pressing the liquid dispensing pump of the liquid dispensing bottle 8 to dispense liquid.

[0042] The side of the housing is provided with a hanging plate 9 that can be fixed to the wall. The hanging plate has through holes and is detachably connected to the housing, so that the automatic liquid dispensing device can be hung on the wall.

[0043] The bottom of the lower shell 3 has button holes 31, indicator light holes 33, and infrared light holes 32. Two buttons on the PCB board (one power button and one function button) are corresponding to the button holes 31 (one on each side), and two infrared lights on the PCB board are corresponding to the two infrared light holes 32. After the upper and lower shells are closed, indicator light holes 33 are provided, corresponding to the indicator lights on the PCB board. The right end of the toggle lever 13 has a groove that engages with the dispensing rod on the dispensing bottle 8 to fix the dispensing rod, ensuring that it is always directly in front of the dispensing bottle and will not shift to either side, making it easier for users to dispense the liquid.

[0044] Example 2:

[0045] like Figure 1-4 As shown, this embodiment provides an automatic liquid dispensing monitoring and management system, including a dispensing bottle 8, an electronic tag 4, a smart gateway, a management platform, and an automatic dispensing device. The automatic dispensing device is movably connected to the dispensing bottle 8, and the electronic tag 4 is installed on the pump head of the dispensing bottle 8. The automatic dispensing device includes a PCB board 5, on which a main control chip, an NFC module, and a LoRa communication module are installed. The input terminal of the NFC module is electrically connected to the electronic tag 4, and the output terminal of the NFC module is electrically connected to the input terminal of the main control chip. The output terminal of the main control chip is electrically connected to the LoRa communication module, and the LoRa communication module is communicatively connected to the input terminal of the smart gateway. The output terminal of the smart gateway is communicatively connected to the management platform. The NFC module includes an NFC chip, a crystal oscillator circuit submodule, a card reader antenna, and a power supply unit. The NFC chip is electrically connected to the crystal oscillator circuit submodule, the card reader antenna, and the power supply unit, respectively.

[0046] The electronic tag is a set of codes that can be recognized by an NFC module. The electronic tag is affixed to or embedded in the pump head of the dispensing bottle (i.e., the disinfectant bottle). The dispensing bottle contains disinfectant. If the disinfectant used does not have an electronic tag or the electronic tag cannot be recognized by the corresponding automatic dispensing device, it is illegal. It should be noted that the dispensing bottle 8 is merely a placement point for the electronic tag 4. After use, the electronic tag is discarded along with the dispensing bottle 8. In this way, the automatic dispensing monitoring and management system of this application can manage the dispensing bottles.

[0047] The automatic dispensing device can transmit the number of times and duration of dispensing, as well as the current dispensing volume setting, to the management platform. The management platform will pre-set parameters such as the liquid capacity of each liquid bottle and the single dispensing volume of the dispensing device at different dispensing levels, thereby accurately calculating the amount of disinfectant used.

[0048] The automatic dispensing device transmits the dispensing time to a management platform. The platform then accurately records the time healthcare workers spend using hand sanitizer, providing data on hand hygiene compliance and tracking staff adherence. This enhances hand hygiene compliance rates in healthcare institutions and reduces the need for manual statistical work.

[0049] like Figure 5 The diagram shows the structure of the PCB circuit board, which includes the main control chip, NFC module and LoRa communication module, infrared sensing circuit, infrared lamp, MOTO module, power supply module and indicator light module. It should be noted that the positions of the components on the PCB board in this application are not fixed and can be adjusted according to the actual situation.

[0050] The card reader antenna in the NFC module reads the data from the electronic tag. After passing through the NFC module, the legality of the disinfectant currently in use can be verified, ensuring the exclusivity of the disinfectant. The automatic dispensing device will not work if the disinfectant is not legal, which facilitates the management of disinfectants by medical institutions. The verification result is transmitted through the main control chip to the LoRa communication module to communicate the data from the NFC dispensing device to the smart gateway of the system, and then the gateway uploads it to the data management platform.

[0051] It should be noted that this application is not limited to the medical field. As another embodiment of this application, it can be used in scenarios where it is necessary to supervise hand hygiene activities such as disinfectants and hand sanitizers, such as public places such as office buildings, schools, stations, and shopping malls.

[0052] like Figure 6-9The diagram shown is a circuit diagram of an NFC module, which includes an NFC chip, a crystal oscillator circuit submodule, a card reader antenna, and a power supply unit. Figure 6 This is a circuit diagram of an NFC chip. Figure 7 This is a circuit diagram of the crystal oscillator circuit submodule. Figure 8 This is a circuit diagram of the card reader antenna. Figure 9 A circuit diagram of the NFC power supply unit is shown. The NFC chip is electrically connected to the crystal oscillator circuit submodule, the card reader antenna, and the power supply unit. The power supply unit provides power, the card reader antenna reads the output signal of the electronic tag and transmits it to the NFC chip, and the NFC chip controls the crystal oscillator circuit submodule to generate a clock signal, which records the dispensing time. The NFC module is responsible for verifying the legality of the currently used disinfectant; the LoRa communication module is responsible for transmitting the information in the NFC module to the smart gateway. The smart gateway is a router-like communication device that can communicate via 4G, wired network, or WIFI. Data transmission consists of the smart gateway and the communication protocol. The smart gateway is responsible for securely uploading the collected data to the monitoring and management backend database. The management platform is responsible for saving the data uploaded by the smart gateway to the database and processing it according to the user's needs to obtain the required monitoring and management data. The present application's method of transmitting information from the electronic tag and other relevant information to the management platform through the smart gateway via the LoRa communication module, and receiving instructions through the smart gateway when the management platform issues instructions, and transmitting the instructions to the main control chip through the communication connection with the LoRa communication module, are all existing technologies.

[0053] like Figure 10 The diagram shows a circuit diagram of a LoRa communication module. The LoRa communication module includes at least a LoRa communication chip, an antenna, a resistor, and a capacitor. The LoRa communication chip is electrically connected to the main control chip.

[0054] like Figure 11 The diagram shows a schematic of an infrared sensing circuit. The infrared sensing circuit is electrically connected to the main control chip and the infrared lamp. The infrared sensing device consists of at least a logic circuit, an infrared emitting diode, and an infrared receiving diode. Figure 12 The infrared sensing circuit in the diagram only shows the infrared receiving diode, which is part of the logic circuit. When the hand is in the sensing area, the hand will reflect infrared light, which is received by the infrared receiving diode to generate a sensing signal.

[0055] During normal use, when a hand is placed within the sensing area of ​​the infrared sensor, the infrared sensor transmits the sensing signal to the main control chip. Since the main control chip is electrically connected to the speed counter and the drive motor, it can transmit electrical signals to the speed counter and the drive motor. Upon receiving the signal, the drive motor is powered on and rotates clockwise. At the same time, the speed counter records the number of rotations of the drive motor and feeds it back to the main control chip in real time to monitor whether the actual number of rotations of the drive motor has reached the number of rotations set by the main control chip. When the drive motor completes the number of rotations set by the main control chip, the dispensing pump located in the dispensing bottle 8 completes the dispensing of liquid.

[0056] like Figure 12-13 The diagram shown is a circuit diagram of the MOTO module. Figure 12 This is a circuit diagram of a motor drive circuit. Figure 13 This is the wiring harness between the motor and the counter.

[0057] One end of the motor drive circuit is electrically connected to the drive motor in the automatic liquid dispensing device, and the other end is electrically connected to the main control chip. The motor drive chip in the motor drive circuit is used to drive the drive motor and transmit the operating status to the main control chip. The motor drive circuit is electrically connected to the cable between the motor and the counter; the purpose of this connection is to supply power to the drive motor, transmit commands, and provide feedback on operating data.

[0058] When a person places their hand into the infrared sensing area of ​​the liquid dispensing device, the infrared sensing circuit transmits the sensing signal to the main control chip. The main control chip controls the NFC module to verify the legality of the electronic tag. When the verification is successful, the main control chip controls the drive motor and the speed counter to start working, which can automatically record the usage and dispensing time of the automatic liquid dispensing device.

[0059] like Figure 14 The diagram shows the circuit diagram of the power supply module, which is electrically connected to the infrared sensing circuit, the MOTO module, the indicator light module, the main control chip, the NFC module, and the LoRa communication module.

[0060] The power supply module includes at least a DC socket, a power management chip U1, battery cells BAT+ and BAT-, and several capacitors. The power management chip is electrically connected to the battery cells, the DC socket, and the capacitors. This power supply module is the power supply system for the entire PCB board, supplying power to components on the PCB board circuitry, including the LoRa module, NFC module, infrared sensor circuit, and drive motor. Users can choose to use dry cell batteries or a DC socket for power supply; the "3P" pin in the circuit allows for switching between power lines, ensuring circuit safety.

[0061] like Figure 15The diagram shows a circuit diagram of an indicator light module. The indicator light module is electrically connected to the main control chip and includes at least a dual-color indicator light D2, a first current-limiting resistor R1, and a second current-limiting resistor R2. The indicator light module can provide prompts to the user based on system usage, using the color and flashing frequency of the light to indicate machine power-on / off status, operation, fault status, and battery level. In one embodiment of this application, the red light flashes when power is on, turns green when the machine is powered on, indicating normal operation, and remains on during normal operation. When a fault occurs, such as a motor malfunction, the red light illuminates.

[0062] like Figure 16 The diagram shows the circuit of the button module, which is electrically connected to the main control chip. The button module includes at least two buttons. One button controls the power on / off, and the other button is used to set the dispensing volume and other settings of the automatic dispensing device. Different settings can be configured.

[0063] like Figure 17 The diagram shown is a circuit diagram of the main control chip, which controls, manages, and processes data from various modules on the PCB board.

[0064] 1. The automatic liquid discharge monitoring and management system of this application can accurately calculate the amount of disinfectant used;

[0065] 2. It can enforce the management of the expiration date of disinfectant (if the bottle has not been changed after the expiration date, the system will not only issue a prompt, but the machine will also force the dispensing of the liquid to force the bottle to be changed, effectively eliminating the possibility of using expired disinfectant);

[0066] 3. It can ensure the exclusivity of disinfectant; the machine will not work if it is not a legally approved disinfectant, which facilitates the management of disinfectants by medical institutions.

[0067] 4. Medical personnel do not need to wear special equipment, which not only reduces the workload of medical personnel but also reduces equipment costs. Instead, by processing database data and combining it with medical standards, the hand hygiene usage of medical staff can be monitored, thereby improving the "hand hygiene compliance rate".

[0068] 5. This automatic liquid discharge monitoring and management system can also be used in other scenarios that require these functions, such as nursing homes, schools, and supermarkets.

[0069] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
