Description

Technical Field

[0001] This utility model relates to the field of cleaning devices, specifically to a hand sanitizer. Background Technology

[0002] Currently, kindergarten handwashing facilities only have basic dispensing functions and cannot record key data such as children's handwashing time and frequency, making it impossible for kindergartens to develop targeted improvement plans for areas where collective handwashing habits are weak. At the same time, kindergartens also face inconveniences in managing hand sanitizer. Replacing the dispenser bottles relies on teachers' subjective judgment of the remaining amount, which can easily lead to shortages, excessive stockpiling, or expired hand sanitizer in opened bottles. Furthermore, different brands and types of hand sanitizer may have different ingredients; if a product that does not meet child safety standards is mistakenly used, it may cause skin irritation or health risks to children. In addition, health departments are increasingly demanding higher standards for monitoring children's handwashing behavior in kindergartens, and the traditional management model relying on manual recording and verbal reminders can no longer meet the needs of precise and data-driven health management. Utility Model Content

[0003] Based on this, and in response to the aforementioned technical problems, this utility model provides a hand sanitizer dispenser.

[0004] The objective of this utility model can be achieved through the following technical solutions:

[0005] A hand sanitizer dispenser includes a housing and a liquid storage bottle connected to the bottom of the housing. The housing has a receiving cavity, in which a water pump is installed. The water pump has an inlet and an outlet. The inlet of the water pump is connected to the liquid storage bottle. An outlet pipe is installed at the top of the receiving cavity, and its inlet is connected to the outlet of the water pump. The spray nozzle is connected to the outside. A sensor head is provided on the housing below the spray nozzle. A control main board is also installed in the receiving cavity. An electronic tag is provided on the top outer wall of the liquid storage bottle. The receiving cavity also has an identification unit for identifying the electronic tag and a communication unit for transmitting data to a network. The communication unit, identification unit, water pump, and sensor head are all electrically connected to the control main board.

[0006] Using the above technical solution, information such as the brand, batch, ingredients, and production date of the hand sanitizer can be pre-recorded via an electronic tag. The identification unit reads the electronic tag on the storage bottle and transmits the information to the control board. If the information does not match, the control board will prevent dispensing, thus ensuring safe use. During use, the sensor detects the arm and transmits the information to the control board, which then activates the water pump to dispense the sanitizer. The control board automatically records the time of each child's handwashing, the amount of hand sanitizer used in the storage bottle, and the remaining amount, and uploads this information to the management platform via the communication unit. This allows the administrator to view the frequency and duration of children's handwashing in the background. The administrator can also use data analysis to identify weaknesses in children's collective handwashing habits, such as low rates of handwashing before and after meals, or inadequate handwashing after outdoor activities, thereby optimizing hygiene management processes. By recording the number of water pump sprays, the control board can monitor the remaining hand sanitizer in real time. When the remaining amount is below a threshold, it sends a replacement reminder to the management platform via the communication unit, preventing hand sanitizer shortages due to human error, avoiding excessive stockpiling and resource waste, and preventing expired hand sanitizer, thus achieving refined and intelligent management of consumables. In addition, the park can connect its handwashing data with the health department's monitoring platform to report the health management situation in real time and meet the requirements of standardized supervision.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0030] Please see Figure 1 As shown, this utility model is a hand sanitizer dispenser, including a housing 10 and a liquid storage bottle 20 connected to the bottom of the housing 10.

[0031] Combination Figure 2 and Figure 3 As shown, the housing 10 has a receiving cavity 11. A water pump 12 is installed in the receiving cavity 11. The water pump has an inlet 121 and an outlet 122. The inlet 121 of the water pump 12 is connected to the storage bottle 20. An outlet pipe 13 is installed at the top of the receiving cavity 11. The inlet 131 of the outlet pipe 13 is connected to the outlet 122 of the water pump 12, and the spray nozzle 132 is connected to the outside.

[0032] An electronic tag 21 is installed on the outer wall of the top of the liquid storage bottle 20. A control mainboard 14, an identification unit 15 for identifying the electronic tag 21, and a communication unit 16 for transmitting data to a network are also installed inside the receiving cavity 11. The communication unit 16, the identification unit 15, and the water pump 12 are all electrically connected to the control mainboard 14. Thus, information such as the brand, batch number, ingredients, and production date of the hand sanitizer can be pre-stored through the electronic tag 21. The identification unit 15 reads the electronic tag 21 on the liquid storage bottle and transmits the information to the control mainboard 14. If the information does not match, the control mainboard 14 prevents dispensing, thereby ensuring safe use. The control mainboard 14 can automatically record the time of each child's handwashing, the amount of hand sanitizer used in the liquid storage bottle 20, and the remaining amount, and upload this data to the management platform via the communication unit 16. This allows the administrator to view the frequency and duration of children's handwashing in the background; the administrator can also use data analysis to identify weaknesses in children's collective handwashing habits, such as low rates of handwashing before and after meals, and delayed handwashing after outdoor activities, thereby optimizing hygiene management processes. The control board records the number of times the water pump dispenses hand sanitizer, allowing for real-time monitoring of the remaining sanitizer level. When the level falls below a threshold, a replacement reminder is sent to the management platform via the communication unit. This prevents supply disruptions due to human error, avoids excessive stockpiling leading to resource waste, and prevents expired sanitizer in used storage bottles, achieving refined and intelligent management of consumables. Furthermore, the park can connect the handwashing data to the health department's monitoring platform, reporting hygiene management status in real time to meet standardized regulatory requirements.

[0033] In this embodiment, the housing 10 includes a body 101 with openings at the upper and lower ends, an upper cover 102 for sealing the upper opening, and a bottom cover 103 for sealing the lower opening.

[0034] In this embodiment, the bottom housing 103 has a battery cavity 104 and a water pump cavity 105. The water pump 12 is installed in the water pump cavity 105. A battery 17, which provides power to the water pump 12 and the control board 14, is installed in the battery cavity 104. The battery 17 is a rechargeable battery. A USB charging interface is provided on the side of the housing 10, and the USB charging interface is connected to the battery 17 by wires.

[0035] In this embodiment, a mounting groove is formed on the top surface of the upper cover 102. A control switch 19 is installed in the mounting groove to control whether the battery 17 supplies power to the water pump 12.

[0036] In this embodiment, the liquid outlet pipe 13 is fixed to the inner top wall of the housing 10 by the bracket 9.

[0037] like Figure 1 and Figure 2As shown, in this embodiment, a sensing window 31 is provided on the housing 10 below the spray nozzle 132 of the liquid outlet pipe 13.

[0038] like Figure 3 , Figure 4 and Figure 5 As shown, in this embodiment, the liquid storage bottle 20 includes a bottle body 22 and a cap 24 detachably connected to the bottle opening 23 at the top of the bottle body 22. The cap 24 has an integrally formed insert 25 extending downward into the bottle body 22. A conduit 26 extending downward to the bottom of the bottle body 22 is inserted into the insert 25. The inlet 121 of the water pump 12 is inserted into the insert 25 and communicates with the conduit 26.

[0039] Combination Figure 6 , Figure 7 and Figure 8 As shown, in this embodiment, a limiting ring 231 is provided on the outer wall of the bottle opening 23. Multiple protrusions 241 that cooperate with the limiting ring 231 are distributed on the inner wall of the bottle cap 24. Thus, when the bottle cap 24 is fastened to the bottle opening 23, the protrusions 241 on the inner wall of the bottle cap 24 will pass over the limiting ring 231 of the bottle opening 23 during the fastening action, and the upper surface of each protrusion 241 will abut against the lower surface of the limiting ring 231, thereby preventing the bottle cap 24 from detaching upwards from the bottle opening 23. In addition, a limiting block 232 is also provided on the outer wall of the bottle opening 23. A notch 242 is provided on the bottle cap 24 to cooperate with and limit the movement of the limiting block 232. Thus, when the bottle cap is fastened downwards to the bottle opening, the limiting block 232 will insert into the notch 242 to form an interlocking structure, thereby restricting the circumferential movement of the bottle cap 24 around the bottle opening 23.

[0040] Combination Figure 9 and Figure 10 As shown, in this embodiment, a fixing cavity 40 is provided at the bottom of the housing 10. The liquid storage bottle 20 is installed in the fixing cavity 40 by a fixing structure. The fixing structure includes a first positioning block 41 and a second positioning block 42 protruding outward from the outer wall of the bottle cap 24. The fixing cavity 40 has a stepped structure, divided into an upper bottle cap chamber 43 and a lower bottle body chamber 44. The bottle cap 24 is located in the bottle cap chamber 43. The upper outer wall of the bottle body 22 has a step 221, and the upper part of the bottle body 22 is located in the bottle body chamber 44. The inner wall of the bottle cap chamber 43 is provided with a first groove 411 that mates with the first positioning block 41 and a second groove that mates with the second positioning block 42.

[0042] In this embodiment, third grooves 45 are respectively provided on the first positioning block 41 and the second positioning block 42. A vertically extending ridge 46, which cooperates with the corresponding third groove 45, is provided on the inner wall of the bottle cap chamber 43. Additionally, a protrusion 47 is provided on the inner wall of the bottle cap chamber 43. A limiting groove 48, which cooperates with the protrusion 24, is provided on the outer wall of the bottle cap 24.

[0043] The above describes a hand sanitizer dispenser according to this utility model. During assembly, the liquid storage bottle 20 is aligned with the fixing cavity 40 at the bottom of the housing 10, so that the first positioning block 41 and the second positioning block 42 of the bottle cap 24 are respectively engaged in the first groove 411 and the second groove of the bottle cap cavity 43. At the same time, each protrusion 46 is embedded into the corresponding third groove 45, and the protrusion 47 is engaged in the limiting slot 48, thus completing the fixing of the liquid storage bottle. The inlet 121 of the water pump 12 is inserted into the insertion tube 25 and connected to the conduit 26. The device is turned on by the control switch 19, and the battery 17 supplies power to the water pump 12, the control motherboard 14, and other components. When washing hands, children place their hands near the sensor window 31 below the spray nozzle 132 on the dispensing pipe 13 of the hand sanitizer dispenser 10. The sensor 32 detects the hand and transmits a signal to the control board 14. The control board 14 then activates the water pump 12, which draws hand sanitizer from the storage bottle 20 via the conduit 26, delivers it to the dispensing pipe 13, and dispenses it from the spray nozzle 132 for the child to wash their hands. Simultaneously, the communication unit 16 uploads the child's handwashing data to the management platform. When the sensor loses its detection of a hand, the control board 14 stops the water pump from dispensing hand sanitizer.
