[0031] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0032] Please see Figures 1-2 This embodiment of a self-service alcohol spray disinfection device includes a base plate 1, a support chamber 2 fixed to the top surface of the base plate 1, a storage chamber 3 fixed to the top surface of the support chamber 2, and a spray mechanism mounted on the base plate 1. Four rubber feet are fixed to the bottom surface of the base plate 1. A water inlet pipe is fixed to the top surface of the storage chamber 3, and a sealing cap is threaded onto the top of the water inlet pipe. A glass observation window is fixed to the front of the storage chamber 3. During use, alcohol is added to the storage chamber 3 through the water inlet pipe, and the remaining alcohol level is observed through the glass observation window. When in use, the user extends their hand to the front of the support chamber 2. At this time, the spray mechanism automatically detects the human body and then extracts a measured amount of alcohol, atomizing it and spraying it onto the hand for disinfection. It is simple and convenient to use, does not cause a large waste of alcohol, has better practicality, and is easier to promote and use.

[0033] It should be noted that the control method of this application is controlled by a controller. The control circuit of the controller can be implemented by a person skilled in the art through simple programming. The power supply is also common knowledge in the art. Furthermore, this application is mainly used to protect mechanical devices, so the control method and circuit connection will not be explained in detail here.

[0034] Please see Figures 1-3 The spraying mechanism includes a central tube 401 rotatably connected to the front of the support chamber 2, two atomizing tubes 402 fixed to the front of the central tube 401, multiple atomizing nozzles 403 respectively fixed to opposite sides of the two atomizing tubes 402, a tray 404 installed on the top surface of the base plate 1, an infrared detector 405 fixed to the front of the storage chamber 3, and a control component set inside the support chamber 2 for automatically delivering alcohol. When a user stands in front of the device, the infrared detector 405 detects a human body and sends a signal to the controller. The controller automatically extracts a fixed amount of alcohol through the control component and delivers it into the central tube 401, and then sprays it out through the atomizing nozzles 403 on the atomizing tubes 402 to disinfect the user's hands.

[0035] In this embodiment, the central tube 401 is a T-shaped tube, and its rear end extends into the support chamber 2. The two atomizing tubes 402 are close to the left and right ends of the central tube 401, and the multiple atomizing nozzles 403 are distributed at equal intervals. The tray 404 is located below the atomizing tubes 402.

[0036] Please see Figure 4 In this embodiment, the control components include a cylinder 501 fixed to the inner wall of the right side of the support chamber 2, a connecting plate 502 fixed to the left end of the output shaft of the cylinder 501, a connecting rod 503 fixed to the left side of the connecting plate 502, a piston plate 504 fixed to the left end of the connecting rod 503, a sleeve 505 slidably connected to the outer peripheral wall of the piston plate 504, a connecting pipe 506 fixed to the left side of the sleeve 505 and with one end fixed to the bottom surface of the storage chamber 3, a conveying pipe 507 fixed to the left side of the sleeve 505 and with one end rotatably connected to the rear end of the central pipe 401, and a one-way valve 508 fixed to the outer peripheral wall of the connecting pipe 506 and the conveying pipe 507. An infrared detector... After the detector 405 detects a human body, it sends a signal to the controller. The controller controls the cylinder 501 to retract, causing the connecting plate 502 to move to the right. The connecting plate 502, through the connecting rod 503, causes the piston plate 504 to slide to the right inside the sleeve 505, thereby drawing alcohol from the storage chamber 3 into the sleeve 505 through the connecting pipe 506, extracting a certain amount of alcohol. Further, the cylinder 501 extends, causing the connecting plate 502 to move to the left and reset, causing the piston plate 504 to slide to the left inside the sleeve 505, thereby delivering the alcohol through the delivery pipe 507 to the center pipe 401, and then spraying it out through the atomizing nozzle 403 on the atomizing pipe 402.

[0037] In this embodiment, both the connecting pipe 506 and the conveying pipe 507 are L-shaped pipes. The left side of the one-way valve 508 on the connecting pipe 506 is the water inlet and the right side is the water outlet. The left side of the one-way valve 508 on the conveying pipe 507 is the water outlet and the right side is the water inlet. When the piston plate 504 moves to the right to draw alcohol, the one-way valve 508 on the conveying pipe 507 can prevent air from being drawn into the sleeve 505. When the piston plate 504 moves to the left to convey alcohol, the one-way valve 508 on the connecting pipe 506 can prevent alcohol from flowing back into the connecting pipe 506, thus realizing one-way alcohol conveying.

[0038] Please see Figures 3-4 In this embodiment, the control component also includes a toothed plate 509 fixed to the left side of the connecting plate 502, a gear 510 fixed to the outer peripheral wall of the central tube 401 and meshing with the toothed plate 509, a guide rod 511 fixed to the inner wall of the front side of the support chamber 2, and two guide rings 512 slidably connected to the outer peripheral wall of the guide rod 511 and whose bottom ends are fixed to the toothed plate 509. When the connecting plate 502 moves left and right to deliver alcohol, it will also work with the guide rod 511 and the guide rings 512 to drive the toothed plate 509 to move left and right. The toothed plate 509 drives the gear 510 to rotate, and the gear 510 drives the central tube 401 to rotate around the central axis of the gear 510, so that the two atomizing tubes 402 can revolve around the central axis of the gear 510, so as to spray atomized alcohol on the palms and backs of the hands for disinfection.

[0039] The cylinder 501 in the control component drives the piston plate 504 to move, thereby facilitating the extraction and delivery of a fixed amount of alcohol. At the same time, the cylinder 501 also drives the two atomizing tubes 402 to rotate through the toothed plate 509 and the gear 510, so that the atomized alcohol can be sprayed on the palm and back of the hand, increasing the alcohol spraying area and improving the disinfection effect.

[0040] In this embodiment, the connecting rod 503 and the toothed plate 509 are positioned opposite each other. The sleeve 505 has a movable hole on its right side for the connecting rod 503 to pass through. The toothed plate 509 meshes with the top surface of the gear 510. The gear 510 is located inside the support chamber 2. The guide rod 511 is a U-shaped rod and is used to allow the guide ring 512 to slide left and right on its outer peripheral wall.

[0041] The working principle of the above embodiments is as follows:

[0042] (1) When in use, alcohol is added into the storage chamber 3. When the user stands in front of the device, the infrared detector 405 detects the human body and sends a signal to the controller. The controller controls the cylinder 501 to retract, which drives the connecting plate 502 to move to the right. The connecting plate 502 drives the piston plate 504 to slide to the right inside the sleeve 505 through the connecting rod 503, thereby allowing the alcohol inside the storage chamber 3 to be drawn into the sleeve 505 through the connecting pipe 506, extracting a certain amount of alcohol. Furthermore, the cylinder 501 extends, which drives the connecting plate 502 to move to the left. The piston plate 504 is reset, causing it to slide to the left inside the sleeve 505, thereby conveying alcohol through the delivery pipe 507 to the center pipe 401. Then, it is sprayed out through the atomizing nozzle 403 on the atomizing pipe 402. When the piston plate 504 moves to the right to draw alcohol, the one-way valve 508 on the delivery pipe 507 can prevent air from being drawn into the sleeve 505. When the piston plate 504 moves to the left to deliver alcohol, the one-way valve 508 on the connecting pipe 506 can prevent alcohol from flowing back into the connecting pipe 506, thus realizing one-way delivery of alcohol.

[0043] (2) When the connecting plate 502 moves left and right to deliver alcohol, it will also work with the guide rod 511 and the guide ring 512 to drive the toothed plate 509 to move left and right. The toothed plate 509 drives the gear 510 to rotate. The gear 510 drives the central tube 401 to rotate around the central axis of the gear 510, so that the two atomizing tubes 402 can revolve around the central axis of the gear 510, so as to spray the atomized alcohol on the palms and backs of the hands for disinfection.
