Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0030] An infrared sensor hand sanitizer dispenser, such as Figure 1-7As shown, the device includes a body 100 and a cleaning solution bottle 300. A base 200 is provided at the bottom of the body 100. The body 100 is placed on one side of the base 200, and the cleaning solution bottle 300 is placed on the other side of the base 200. The cleaning solution bottle 300 and the body 100 are arranged side by side on the base 200. A pump 400 and a slot 201 are provided on the base 200. The pump 400 and the slot 201 are connected by a hose 500. The pump 400 is connected to the nozzle 103 on the body 100 by the hose 500. In use, the pump 400 pumps the cleaning solution from the cleaning solution bottle 300. The cleaning fluid in the bottle 300 is drawn into the outlet 103 and discharged. A top post 202 is provided in the slot 201. The bottom of the cleaning fluid bottle 300 extends integrally to form a plug part 301. A switch valve 304 is provided in the plug part 301. When the cleaning fluid bottle 300 is placed on the base 200, the plug part 301 is inserted into the slot 201. When the plug part 301 is inserted into the slot 201, the top post 202 in the slot 201 pushes open the switch valve 304, thereby opening the switch valve 304, so that the cleaning fluid in the cleaning fluid bottle 300 flows through the switch valve 304 and enters the slot 201 under the action of gravity.

[0031] An infrared sensor 108 is located behind the dispensing nozzle 103 of the body 100. A circuit board 107 and a battery are located inside the body 100. The circuit board 107 is electrically connected to the battery, the infrared sensor 108, and the liquid pump 400. A button 101 is located on the top of the body 100. When in use, the cleaning fluid bottle 300 is inserted into the base 200 and fixed. The button 101 is pressed to open the machine. The user places his hand under the infrared sensor 108, and the infrared sensor 108 transmits a signal to the circuit board 107. The circuit on the circuit board 107 controls the liquid pump 400 to start, and the liquid pump 400 draws the cleaning fluid to the dispensing nozzle 103 for output.

[0032] like Figure 2 The cleaning fluid bottle 300 is the same height as the body 100. A top cover is provided on the top of the cleaning fluid bottle 300. Opening the top cover allows for easy addition of cleaning fluid or cleaning of the cleaning fluid bottle 300. Compared to disposable cleaning fluid bottles 300 that need to be replaced, the cleaning fluid bottle 300 in this embodiment can be repeatedly filled with cleaning fluid without discarding empty bottles, reducing waste of materials. In addition, the large opening at the top of the cleaning fluid bottle 300 allows for easy and thorough cleaning of the inside of the cleaning fluid bottle 300 to prevent bacterial growth. At the same time, the structure of the plug-in part 301 and the slot 201 allows the cleaning fluid bottle 300 to be placed on the base 200 and the switch valve 304 to be opened. When the cleaning fluid bottle 300 is removed, the switch valve 304 is closed.

[0033] like Figure 3 , Figure 5As shown, the switching valve 304 includes a sealing plug 305, a sliding member 306, a spring 309, and a valve passage 307. The sealing plug 305 abuts against the opening of the switching valve 304 to seal the opening. An insertion portion 301 is integrally formed extending from the bottom of the cleaning fluid bottle 300. The insertion portion 301 can be inserted into the slot 201 in the base 200. The interior of the insertion portion 301 is hollow to form the valve passage 307. A bracket 308 is integrally formed inside the valve passage 307. The sliding member 306 is slidably mounted on the bracket 308. The sealing plug... 305 is set on the top of the slider 306. The sealing plug 305 is preferably made of rubber or silicone. The top of the slider 306 is conical for installing the sealing plug 305. The spring 309 is set on the slider 306. The two ends of the spring 309 abut against the bracket 308 and the bottom of the slider 306, respectively. The elastic force of the spring 309 makes the bottom of the slider 306 move away from the bracket 308. The sealing plug 305 on the top of the slider 306 presses against the valve passage 307 of the switch valve 304 to close the switch valve 304.

[0034] Under the elastic force of the spring 309, the sealing plug 305 presses against the valve channel 307 at the bottom of the cleaning fluid bottle 300 to seal the bottom of the cleaning fluid bottle 300 and prevent the cleaning fluid from leaking out. When the cleaning fluid bottle 300 is inserted into the base 200, the switch valve 304 in the insertion part 301 and the top post 202 in the slot 201 press against each other, and the insertion part 301 at the bottom of the cleaning fluid bottle 300 is inserted into the slot 201 of the base 200. The bottom of the sliding member 306 abuts against the top post 202. Under the weight of the cleaning fluid bottle 300 itself, the upward pressure causes the sliding member 306 to overcome the elastic force of the spring 309, and the sliding member 306 moves upward in the valve channel 307. The sliding stopper 305 moves upward together with the sliding member 306, opening the switch valve 304. The cleaning liquid in the cleaning liquid bottle 300 flows out into the slot 201 through the valve channel 307 under its own gravity, filling the entire space of the slot 201. The pump 400 and the slot 201 are connected by a hose 500. After the pump 400 starts, it draws the cleaning liquid in the slot 201 onto the dispensing nozzle 103 and outputs it from the dispensing nozzle 103. Due to the limited space in the slot 201, the pump 400 can only draw the cleaning liquid in the slot 201 at a time, thus limiting the amount of hand sanitizer dispensed and reducing waste of resources.

[0035] like Figure 3 , Figure 5 As shown, in this embodiment, the outer periphery of the plug portion 301 is provided with a plurality of concave and convex surfaces 302. A sealing ring 303 is installed on the concave and convex surfaces 302. When the plug portion 301 is inserted into the slot 201, the sealing ring 303 seals with the inner wall of the slot 201 to prevent hand sanitizer from seeping out from the gap between the plug portion 301 and the slot 201.

[0036] like Figure 3As shown, in this embodiment, a buffer chamber 203 is provided in the slot 201, and the buffer chamber 203 temporarily stores the cleaning fluid flowing out from the bottom of the cleaning fluid bottle 300.

[0037] In some embodiments, a sponge layer is provided in the buffer chamber 203, and the cleaning liquid flows through the sponge layer to form a large amount of foam when it is discharged.

[0038] like Figure 2 , Figure 7 As shown, a battery compartment 104 is provided on the back of the body 100. The battery compartment 104 is used to hold dry batteries. The dry batteries provide power to the circuit board 107 and the liquid pump 400 inside the body 100. Slots 105 are provided on the upper and lower parts of the battery compartment 104, and buckles 106 are provided on the upper and lower parts of the battery cover. After the dry batteries are put into the battery compartment 104, the buckles 106 on the lower part of the battery cover are inserted into the slots 105, and the battery cover is snapped into place to close the battery compartment 104.

[0039] like Figure 4-6 As shown, a limiting part 109 is provided on the back of the body 100, and a positioning part 311 is provided on the back of the cleaning fluid bottle 300. During installation, the positioning part 311 is snapped into the limiting part 109, fixing the upper part of the cleaning fluid bottle 300 to the body 100 in the X and Y axis directions. A positioning groove 310 is provided on the cleaning fluid bottle 300, and a positioning post 204 is provided on the base 200. During installation, the positioning post 204 is inserted into the positioning groove 310, fixing the bottom of the cleaning fluid bottle 300 to the body 100 in the X and Y axis directions. In this way, the cleaning fluid bottle 300 is fixed side by side on one side of the body 100 by the double locking of the limiting part 109 and the positioning part 311, and the positioning post 204 and the positioning groove 310.

[0040] like Figure 4 As shown, the limiting part 109 includes a groove 110, a limiting wall 111, and ribs. The groove 110 is integrally injection molded on the back of the body 100, the limiting wall 111 is disposed on the edge of the groove 110, and the ribs are disposed inside the groove 110; Figure 5-6 As shown, a positioning part 311 is provided on the cleaning liquid bottle. The positioning part 311 includes an arc-shaped part 312, a flat part 313, and a concave part 314. The arc-shaped part 312, the flat part 313, and the concave part 314 are integrally formed on the positioning part 311. During installation, the positioning part 311 is snapped into the groove 110. When the cleaning liquid bottle 300 is pressed, the ribs in the groove 110 are snapped into the concave part 314 along the arc-shaped part 312 and the flat part 313 and fixed. At the same time, the limiting wall 111 limits the positioning part 311, so that the cleaning liquid bottle 300 is fixed in the X-axis and Y-axis directions.

[0041] In some embodiments, the pump 400 is a peristaltic pump. The peristaltic pump can output and deliver solid, liquid, or gas-liquid mixed phase fluids, so that the hand sanitizer dispenser can spray liquid cleaning solutions, as well as gel-like cleaning lotions or foams. This allows the hand sanitizer dispenser to spray multiple types of cleaning solutions. At the same time, the peristaltic pump can run dry to prevent backflow and prevent the pump 400 from running dry and being damaged.

[0042] The above description is only a preferred embodiment of the present utility model. Therefore, all equivalent changes or modifications made to the structure, features and principles described in the claims of the present utility model patent application are included in the scope of the present utility model patent application.
