Description

Technical Field

[0001] This utility model belongs to the technical field of hygiene and disinfection, and in particular relates to a hand sanitizer. Background Technology

[0002] People have increasingly higher requirements for personal hygiene, especially after using the toilet, where handwashing is necessary. However, simple handwashing is not very effective for disinfection. Therefore, many restrooms are equipped with wall-mounted hand sanitizers for convenient hand disinfection. Currently, the disinfection method is a press-type hand sanitizer, which requires repeated application with both hands after pressing, which is very troublesome and inefficient. As a result, patent application number 202221514865.6 discloses a sensor-activated hand atomizing disinfection device. Although this structure achieves the function of atomizing liquid to disinfect hands, it requires simultaneous sensing of hand status by lower and upper motion recognition sensors to spray. This makes the structure relatively complex and bulky. It can only be placed horizontally and cannot be hung. Moreover, the water tank cannot be disassembled, making cleaning inconvenient. Therefore, improvements are needed. Utility Model Content

[0003] The purpose of this invention is to provide a hand sanitizer that solves the problems of existing hand atomizing sanitizers, such as complex structure, large overall size, only horizontal placement and no hanging, and inconvenient cleaning due to non-removable water tanks.

[0004] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0005] This utility model relates to a hand sanitizer, comprising a base with a detachable L-shaped liquid container inserted into its front end. A hanging hole is provided at the rear of the base. A peristaltic pump, an air pump, and a main control board are housed within the base. The input end of the peristaltic pump is connected to the output port of the L-shaped liquid container. An atomizing jet sensor assembly is located below the front end of the base. The atomizing jet sensor assembly includes an upper sensor cover and a lower sensor cover connected to each other, forming a receiving cavity. A sensor for sensing hands and an atomizing nozzle communicating with the receiving cavity are located below the lower sensor cover. The main control board is electrically connected to the peristaltic pump, the air pump, and the sensor. An air inlet and a liquid inlet communicating with the receiving cavity are provided on the upper sensor cover. The output end of the peristaltic pump is connected to the liquid inlet via a water pipe, and the output port of the air pump is connected to the air inlet via an air pipe.

Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0032] Example 1

[0033] Please see Figure 1-12As shown, this embodiment discloses a hand sanitizer, including a base 1. A detachable L-shaped liquid container 2 is inserted into the front end of the base 1. In this embodiment, an L-shaped mounting groove 103 is provided at the front end of the base 1, and the L-shaped liquid container 2 is inserted into the L-shaped mounting groove 103. A hanging hole 4 is provided at the rear of the base 1. A peristaltic pump 5, an air pump 6, and a main control board 7 are provided inside the base 1. In order to achieve an isolated distribution between the pump body and the main control board 7, and ultimately achieve a water and electricity isolation layout, further improving the service life of the internal electrical equipment, the base 1... The interior also includes a motor control box 18, which comprises a matching upper cover 181 and a lower cover 182. The main control board 7 is located on the side of the motor control box 18. The peristaltic pump 5 and the air pump 6 are installed between the upper cover 181 and the lower cover 182. A maintenance port 101 aligned with the lower cover 182 is provided at the rear of the base 1. A base cover plate 3 is fixed to the maintenance port 101. The input end of the peristaltic pump 5 is connected to the output port of the L-shaped liquid container 2. For easy disassembly, the peristaltic pump 5... The input end is connected to a liquid supply connector 102 located at the front end of the base 1. The output port of the L-shaped liquid container 2 (located at the rear of the L-shaped liquid container 2, not marked in the figure) is inserted into the liquid supply connector 102. An atomizing jet sensor box assembly 8 is provided below the front end of the base 1. The atomizing jet sensor box assembly 8 includes an upper sensor box cover 801 and a lower sensor box cover 802 connected to each other. The upper sensor box cover 801 and the lower sensor box cover 802 form a receiving cavity. A sensing element is provided below the lower sensor box cover 802. The device includes a hand sensor 803 and an atomizing nozzle 804 connected to the receiving cavity. The atomizing nozzle 804 is tilted and has its outlet facing downward. The main control board 7 is electrically connected to the peristaltic pump 5, the air pump 6, and the sensor 803. The sensor box cover 801 is provided with an air inlet connector 805 and a liquid inlet connector 806 connected to the receiving cavity. The output end of the peristaltic pump 5 is connected to the liquid inlet connector 806 through a water pipe 25. The output port of the air pump 6 is connected to the air inlet connector 805 through an air pipe 26. The base 1 is provided with a start switch 701 connected to the main control board 7.

[0034] Preferably, to achieve a concealed design for the L-shaped liquid pitcher 2 and to prevent children from opening the inlet 9 at will, the L-shaped liquid pitcher 2 has an inlet 9 at its front end. A hinge shaft 10 is located on each of the two sides below the front end of the base 1. A housing 11 located at the front end of the base 1 is hinged between the two hinge shafts 10. To achieve a locking function, a second latch 13 is provided above the base 1, and a lock seat 14 is provided above the housing 11. A lock cylinder 15 rotates within the lock seat 14. A locking tongue 16 is provided on the side of the lock seat 14, which, after rotation, can be engaged with the second latch 13 for limiting its position. A locking block 17 is provided on the side of the lock cylinder 15, which inserts into the locking tongue 16 and drives the locking tongue 16 to rotate. A U-shaped insertion hole 12 is provided on the housing 11 to facilitate the insertion of the atomizing nozzle 804. By setting the above structure, the L-shaped liquid pitcher 2 is designed to prevent children from opening the inlet at will.

[0035] Preferably, to avoid liquid spillage on the ground causing slipperiness and pollution, a water collection tray 19 is hinged to the front end of the outer shell 11 and located below the U-shaped through hole 12. A buckle groove 20 is provided on the front end of the outer shell 11, and a buckle 21 that cooperates with the buckle groove 20 is provided on the side of the water collection tray 19 facing the outer shell 11. In this embodiment, by hinged to the lower end of the outer shell 11, a foldable water collection tray 19 is ultimately used to collect waste liquid in the later stage, avoiding liquid spillage on the ground causing slipperiness and pollution. At the same time, the water collection tray 19 can be folded, so that it does not take up space when not in use or when packaged, making it more compact.

[0036] To achieve automatic liquid level detection, the L-shaped liquid container 2 is equipped with a liquid level sensor 24 electrically connected to the main control board 7. In this embodiment, there are two liquid level sensors 24, one for low-level detection and one for high-level detection. One sensor is located at the upper end of the L-shaped liquid container 2 to detect the highest liquid level inside, and the other is located at the lower end of the L-shaped liquid container 2 to detect the lowest liquid level inside. When both the highest and lowest liquid level sensors 24 detect a signal, it indicates that the L-shaped liquid container 2 is full. When neither the highest nor the lowest liquid level sensor 24 detects a signal, it indicates that the L-shaped liquid container 2 is empty. If the highest liquid level sensor 24 detects a signal but the lowest liquid level sensor 24 does not detect a signal, it indicates that the L-shaped liquid container 2 is half-full.

[0037] To provide reminders for various functional states, one or more LED lights 22 are also provided above the front end of the base 1. In this embodiment, for example... Figure 11As shown, there are five LED lights 22, which serve as a power indicator for displaying the power status, a working status indicator for displaying the device's working status, a full liquid indicator for displaying the liquid level of the L-shaped liquid jug 2, a half liquid indicator for displaying the liquid level of the L-shaped liquid jug 2, and a no liquid indicator for displaying the liquid level of the L-shaped liquid jug 2. Therefore, for ease of installation, the five LED lights 22 are integrated into one LED light board, which is electrically connected to the main control board 7. In this embodiment, the LED lights 22 are used to remind users of the device's usage status and internal water level.

[0038] Preferably, the front end of the L-shaped liquid container 2 is threadedly connected to the inlet 9 with a rotating nut cap 23. In this embodiment, the rotating nut cap 23 can be used to seal the unused inlet 9.

[0039] The working principle of this structure is as follows:

[0040] In use, the device is suspended on the wall using the hanging hole 4 at the rear of the base 1 and screws. Cleaning solution is stored in the L-shaped liquid reservoir 2. Pressing the side start switch 701 activates the device. When a hand is detected by the sensor 803, the peristaltic pump 5 and the air pump 6 start simultaneously. The peristaltic pump 5 draws the cleaning solution from the L-shaped liquid reservoir 2 and delivers it to the receiving cavity. The air pump 6 blows air into the receiving cavity, ultimately achieving atomization of the gas and liquid mixture, which is then sprayed from the atomizing nozzle 804 to disinfect the hands below. Therefore, this structure allows for convenient hanging of the entire device, while maintaining a compact size and simple structure. Furthermore, the addition of the L-shaped liquid reservoir 2 increases the liquid storage capacity. Since the L-shaped liquid reservoir 2 is detachably connected to the base 1, it can be cleaned later, preventing residual waste liquid from affecting the sterilization effect. This structure can be widely used for hand disinfection in public places such as food factories, pharmaceutical factories, and chain stores.

[0041] It should also be noted that the specific structure and operation of the sensor 803, the model of the main control board 7, the models of the peristaltic pump 5 and the air pump 6, and how the main control board 7 is electrically connected to each component to achieve control are all conventional technologies in the field, and therefore will not be described in detail.

[0042] The above are merely preferred embodiments of the present utility model and do not limit the present utility model. Any modifications, equivalent substitutions, or improvements made to the technical solutions described in the foregoing embodiments, or to some of the technical features, shall fall within the protection scope of the present utility model.
