Description
Technical Field
[0001] This invention relates to the field of disinfection equipment technology, specifically to a hand hygiene disinfection device based on facial recognition and its usage method. Background Technology
[0002] In the healthcare system, hand sanitizers are widely used. Medical staff must perform hand hygiene, i.e., clean their hands with hand sanitizer, when putting on and taking off protective clothing, contacting patients, drawing blood, and handling sterile items. Disinfection is especially important in the prevention and control of highly contagious diseases such as drug-resistant bacteria. In particular, the infection rate in ICUs is higher than in ordinary wards, and the infection process is more complex. Medical staff, including nursing assistants, have the highest probability of contact with critically ill patients during diagnosis and treatment.
[0003] Maintaining hand hygiene is the most basic, simple, and effective means of preventing and controlling the spread of pathogens, thereby reducing the incidence of hospital-acquired infections. Most existing hand hygiene disinfection devices use hydraulic pumps and hoses to extract disinfectant. However, hose extraction always leaves residual disinfectant in the pump or tubing, resulting in incomplete disinfectant use. Furthermore, when the device is not used for an extended period, the residual disinfectant may solidify. The dispensing nozzle of existing hand hygiene devices is unprotected, meaning users may inadvertently touch it during use, leading to bacterial or viral contact and, in severe cases, cross-infection. In modern life, mobile phones, tablets, and watches are frequently used, and these items also harbor a large number of bacteria, necessitating regular disinfection to ensure personal hygiene. Summary of the Invention
[0004] To overcome the aforementioned technical problems, the present invention aims to provide a hand hygiene disinfection device based on facial recognition and its usage method. An ultraviolet pulse lamp rises to the center of two semi-circular shells, emitting instantaneous intense light to disinfect items such as mobile phones. Multiple reflective strips on the inner wall of the semi-circular shells reflect the pulsed light, disinfecting the reverse side of items like mobile phones, thus improving disinfection coverage. The pulse disinfection mechanism can quickly disinfect multiple items, and the reflection ensures complete irradiation of items, improving the disinfection effect on personal items. Two leak-proof covers not only prevent disinfectant dripping and waste but also protect the dispensing head, preventing cross-infection caused by others touching the dispensing head, thereby improving the overall hygiene of hospitals or other locations. The automatic dispensing mechanism allows the storage tank to first flow into a fixed cylinder before dispensing through the dispensing head, eliminating the need for a hydraulic pump and hoses. The liquid is extracted, and gravity allows the liquid in the tank to flow out completely, ensuring more complete use of the disinfectant and minimizing waste. When the storage tank is empty, a certain amount of disinfectant can be temporarily stored in the fixed cylinder, allowing for continued use of the hand sanitizing device and increasing the number of uses before adding more disinfectant. By simultaneously performing hand sanitizing and personal item disinfection, the overall disinfection process is shortened. After hand sanitizing, the cylinder descends again, moving two semi-circular shells out for easy retrieval of personal items, thus improving the device's efficiency and allowing users to complete personal hygiene in a shorter time. When adding disinfectant, the storage tank is rotated, and the abutting column gradually moves away from the liquid adding column. Under the action of the return spring, the sealing block blocks the two liquid outlets, preventing disinfectant from dripping. New disinfectant is then poured into the funnel-shaped liquid adding column, preventing contamination of the device's interior due to liquid dripping during addition.
[0005] The objective of this invention can be achieved through the following technical solutions:
[0006] A hand hygiene disinfection device based on facial recognition includes a facial recognition mechanism, an automatic liquid dispensing mechanism fixedly installed on the top of the facial recognition mechanism, and a pulse disinfection mechanism installed at the bottom of the automatic liquid dispensing mechanism.
[0007] The automatic liquid dispensing mechanism includes a fixed cylinder, a liquid dispensing head fixedly connected to the bottom of the fixed cylinder, a storage tank screwed onto the top of the fixed cylinder, a support hoop fixedly fitted onto the outside of the fixed cylinder, a valve plate inside the fixed cylinder, a rotating shaft rotatably connected to the fixed cylinder fixedly connected to the valve plate, an output end of a servo motor fixedly connected to the end of the rotating shaft, an incomplete gear fixedly fitted onto the outer wall of the rotating shaft, two racks symmetrically arranged on both sides of the incomplete gear, inclined columns fixedly connected to the side walls of the two racks, rollers slidingly contacting the inclined surfaces of the inclined columns, one end of a connecting frame rotatably connected to the outside of the rollers, and a leak-proof cover fixedly connected to the other end of the two connecting frames. The leak-proof cover is fitted onto the liquid dispensing head. The leak-proof cover can protect the liquid dispensing head, prevent external objects from contacting it and causing infection, and also prevent residual liquid from dripping and causing waste.
[0008] Furthermore, the face recognition mechanism includes a mobile platform, with omnidirectional wheels fixedly connected to the four corners of the bottom of the mobile platform. A camera is fixedly installed on the side wall of the mobile platform, and a display screen is fixedly installed at the bottom of the camera. An infrared proximity sensor is fixedly installed on the inner wall of the mobile platform, and a storage slot is provided on the mobile platform. The infrared proximity sensor can sense the user's hand to activate the automatic liquid dispensing mechanism to dispense liquid, thereby facilitating the user's hand disinfection.
[0009] Furthermore, the pulse disinfection mechanism includes two semi-circular shells. Multiple partitions are fixedly connected circumferentially at equal intervals inside each of the two semi-circular shells. A placement cavity is provided between adjacent partitions. A fixing block is fixedly connected to the top of each of the two semi-circular shells. A sliding column is fixedly connected to the inner wall of each of the two fixing blocks. A drive frame is slidably sleeved on the outside of each of the two sliding columns. A return spring, fixedly connected to the drive frame, is sleeved on the outside of each sliding column. A sleeve rod is fixedly connected to the center of the side wall of the drive frame. The outside of the sleeve rod is slidably sleeved... A limiting plate is fixedly connected to the moving platform. One end of the bottom of the sleeve rod is rotatably connected to one end of the connecting rod, and the other end of the connecting rod is rotatably connected to the lifting plate. A cylinder is fixedly installed at the bottom of the lifting plate, and an ultraviolet pulse lamp tube is fixedly installed at the top of the lifting plate. Inclined platforms slide against the outer walls of the two semi-circular shells. Both inclined platforms are fixedly connected to the inner sidewall of the storage slot. The pulse disinfection mechanism can quickly disinfect multiple items. The reflection energy allows the items to be completely irradiated by strong light, thereby improving the disinfection effect of personal items.
[0010] Furthermore, a circular plate is fixedly connected to the opening of the storage tank. Two liquid outlet holes are symmetrically opened on the circular plate. A liquid filling column is slidably sleeved at the center of the circular plate. One end of the liquid filling column is funnel-shaped, and the other end of the liquid filling column is fixedly connected to a sealing block that fits into the liquid outlet hole. A return spring is fixedly connected to the circular plate and sleeved on the outside of the liquid filling column. A rotating plug is screwed into the inside of the liquid filling column. An abutting column that abuts against the liquid filling column is fixedly connected to the inner wall of the fixed cylinder. When the storage tank is removed, the return spring can drive the liquid filling column to slide, so that the sealing block can block the two liquid outlet holes, thereby preventing liquid from dripping and causing contamination.
[0011] Furthermore, an L-shaped rod is slidably connected to the inclined column, and a support plate is fixedly connected to the end of the L-shaped rod. A limit rod is fixedly connected to the outer wall of the support plate. The connecting frame is slidably connected to the limit rod. A compression spring fixedly connected to the connecting frame is sleeved on the outside of the limit rod. The limit rod can restrict the connecting frame, while the L-shaped rod can limit the vertical position of the inclined column.
[0012] Furthermore, a collection plate is slidably inserted into the moving platform, thus enabling the collection of any dripping residual liquid.
[0013] Furthermore, multiple reflective strips are fixedly connected in a ring at equal intervals on the arc-shaped inner wall of the semi-circular shell. By fixing the reflective strips on the inner wall of the semi-circular shell, pulsed strong light can be reflected. The reflected strong light can disinfect the back of items such as mobile phones, thereby improving the disinfection coverage.
[0014] A method for using a hand sanitizing device based on facial recognition includes the following steps:
[0015] Step 1: The camera in the device can record facial information, so that when hand sanitizing, the device can first recognize and verify personal information by facial recognition. After verification, the device will start the pulse disinfection mechanism.
[0016] Step 2: The cylinder drives the lifting plate and the ultraviolet pulse lamp tube to descend. The lifting plate can drive the connecting rod at the end to rotate. The end of the connecting rod can drive the sleeve rod and the drive frame to move. In turn, the drive frame can drive the sliding column and the semi-circular shell to move. During the movement, the reset spring 2 drives the sliding column to slide on the drive frame. Thus, the two semi-circular shells maintain the inclined plane of the inclined platform and slide. When the two semi-circular shells move out of the storage slot, the two semi-circular shells are located on both sides of the moving platform. Then, the user can put their mobile phone, watch, personal ID card, etc. into the placement cavity.
[0017] Step 3: The cylinder can drive the lifting plate to rise, which in turn drives the drive frame and the two semi-circular shells to move back into the storage tank via the connecting rod. At the same time, the ultraviolet pulse lamp will rise to the center of the two semi-circular shells and emit instantaneous strong light to perform pulse disinfection and sterilization on items such as mobile phones. The multiple reflective strips on the inner wall of the semi-circular shells can reflect the pulse strong light, thereby disinfecting the back of mobile phones and other items, improving the disinfection coverage. The pulse disinfection mechanism can quickly disinfect multiple items.
[0018] Step 4: The user needs to place their hand under the dispensing head. At this time, the infrared proximity sensor can detect the human hand and then activate the servo motor in the automatic dispensing mechanism. The output of the servo motor can drive the rotating shaft and valve plate to rotate, so that the hand sanitizer in the fixed cylinder can flow into the dispensing head. At the same time, the rotating shaft drives the incomplete gear to rotate one revolution. During the rotation, the incomplete gear can mesh with two racks, thereby driving the two racks to rise and fall in opposite directions. The rise and fall of the racks can drive the inclined column and the roller to abut against each other, so that the roller can roll on the inclined surface of the inclined column, thereby driving the two connecting frames to move in opposite directions. The two connecting frames can drive the two closed leak-proof covers to separate, so that the hand sanitizer flows out of the dispensing head and falls onto the user's hand, allowing the user to rub and disinfect their hands.
[0019] Step 5: By simultaneously disinfecting hands and personal belongings, the overall disinfection process is shortened. After hand disinfection, the cylinder descends again, moving the two semi-circular shells out, making it easier for users to retrieve their belongings and thus improving the device's efficiency.
[0020] The beneficial effects of this invention are:
[0021] 1. The ultraviolet pulse lamp rises to the center of the two semi-circular shells, emitting a burst of intense light to disinfect items such as mobile phones. Multiple reflective strips on the inner wall of the semi-circular shells reflect the intense pulse light, thus disinfecting the reverse side of items such as mobile phones, improving the disinfection coverage. The pulse disinfection mechanism can quickly disinfect multiple items, and the reflection ensures that the items are completely irradiated by the intense light, thereby improving the disinfection effect on personal items.
[0022] 2. The two leak-proof covers not only prevent disinfectant from dripping and wasting, but also protect the dispensing head, preventing others from touching it and causing bacterial infection and cross-infection. This improves the overall hygiene of hospitals and other places. The automatic dispensing mechanism allows the liquid to flow from the storage tank into the fixed cylinder first, and then be dispensed through the dispensing head. Therefore, there is no need to rely on hydraulic pumps and hoses to extract the liquid. Under the action of gravity, the liquid in the tank can flow out completely, thus making more complete use of the disinfectant and reducing waste. When the disinfectant in the storage tank is empty, a certain amount of disinfectant can be temporarily stored in the fixed cylinder, so the hand sanitizer can continue to be used, which can increase the number of uses before adding disinfectant.
[0023] 3. By simultaneously disinfecting hands and personal items, the time required for the entire disinfection process can be reduced. After hand disinfection is completed, the cylinder descends again, causing the two semi-circular shells to move out, making it easier for users to retrieve their belongings. This improves the efficiency of the device and allows users to complete personal hygiene in a shorter time.
[0024] 4. When adding disinfectant, the storage tank needs to be rotated, and then the abutting column gradually moves away from the liquid adding column. Under the action of the return spring, the sealing block will block the two liquid outlet holes, thus preventing the disinfectant from dripping from the liquid outlet holes. Then, new disinfectant is poured into the funnel-shaped liquid adding column. This way, the inside of the device will not be contaminated due to liquid dripping when adding liquid.

[0040] The face recognition mechanism 100 includes a mobile platform 101. Universal wheels 102 are fixedly connected to the four corners of the bottom of the mobile platform 101. A camera 104 is fixedly installed on the side wall of the mobile platform 101, and a display screen is fixedly installed at the bottom of the camera 104. An infrared proximity sensor 105 is fixedly installed on the inner wall of the mobile platform 101. A storage slot 103 is provided on the mobile platform 101. The infrared proximity sensor 105 can sense the user's hand, thereby activating the automatic liquid dispensing mechanism 200 to dispense liquid, facilitating hand disinfection.

[0041] The pulse disinfection mechanism 300 includes two semi-circular shells 301. Multiple partitions 302 are fixedly connected annularly at equal intervals inside each semi-circular shell 301. A placement cavity 304 is provided between adjacent partitions 302. A fixing block 305 is fixedly connected to the top of each semi-circular shell 301.

The pulse disinfection mechanism 300 can quickly disinfect multiple items. The reflection energy can make the items completely irradiated by strong light, thereby improving the disinfection effect on personal items. Multiple reflective strips 303 are fixedly connected in a ring at equal intervals on the arc-shaped inner wall of the semi-circular shell 301. By fixing the reflective strips 303 on the inner wall of the semi-circular shell 301, the pulse strong light can be reflected. The reflected strong light can disinfect the back of items such as mobile phones, improving the disinfection coverage.
[0042] A method for using a hand sanitizing device based on facial recognition includes the following steps:
[0043] Step 1: The camera 104 in the device can record facial information, so that when hand sanitizing, the device can first recognize and verify personal information by facial recognition. After the verification is completed, the device starts the pulse disinfection mechanism 300.
[0044] Step 2: Cylinder 313 drives the lifting plate 312 and ultraviolet pulse lamp tube 314 to descend. The lifting plate 312 can drive the connecting rod 311 at the end to rotate. The end of the connecting rod 311 can drive the sleeve rod 309 and the drive frame 308 to move. Thus, the drive frame 308 can drive the sliding column 306 and the semi-circular shell 301 to move. During the movement, the reset spring 307 drives the sliding column 306 to slide on the drive frame 308. Thus, the two semi-circular shells 301 maintain the inclined plane sliding with the inclined platform 315. When the two semi-circular shells 301 move out of the storage slot 103, the two semi-circular shells 301 are located on both sides of the moving platform 101. Then, the user can put their mobile phone, watch, personal ID card, etc. into the placement cavity 304.
[0045] Step 3: Cylinder 313 can drive the lifting plate 312 to rise, thereby driving the drive frame 308 and the two semi-circular shells 301 to move back into the storage tank 103 via connecting rod 311. At the same time, the ultraviolet pulse lamp tube 314 will rise to the center position of the two semi-circular shells 301. The ultraviolet pulse lamp tube 314 emits instantaneous strong light, which can perform pulse disinfection and sterilization on mobile phones and other items. The multiple reflective strips 303 on the inner wall of the semi-circular shell 301 can reflect the pulse strong light, thereby disinfecting the back of mobile phones and other items, improving the disinfection coverage. The pulse disinfection mechanism 300 can quickly disinfect multiple items.
[0046] Step 4: The user needs to place their hand under the dispensing head 202. At this time, the infrared proximity sensor 105 can detect the human hand, and then the servo motor 213 in the automatic dispensing mechanism 200 will be activated. The output of the servo motor 213 can drive the rotating shaft 212 and the valve plate 214 to rotate 360 degrees, so that the hand sanitizer in the fixed cylinder 201 can flow into the dispensing head 202. At the same time, the rotating shaft 212 drives the incomplete gear 215 to rotate one revolution. During the rotation of the incomplete gear 215, it can interact with... Two racks 216 mesh with each other, thereby driving the two racks 216 to rise and fall in opposite directions. The rising and falling of the racks 216 can cause the inclined column 217 and the roller 218 to collide, so that the roller 218 can roll on the inclined surface of the inclined column 217, thereby driving the two connecting frames 219 to move in opposite directions. The two connecting frames 219 can drive the two closed leak-proof covers 220 to separate, so that the liquid outlet 202 flows out disinfectant and falls onto the user's hands, so that the user can rub and disinfect his hands.
[0047] Step 5: By simultaneously disinfecting hands and personal items, the time required for the entire disinfection process can be reduced. After hand disinfection is completed, cylinder 313 descends again, causing the two semi-circular shells 301 to move out, making it easier for users to retrieve their items and thus improving the efficiency of the device.
[0048] Working principle: During use, the camera 104 in the device can record facial information, so that facial recognition and personal information can be verified before hand disinfection. After verification, the device activates the cylinder 313 in the pulse disinfection mechanism 300 to drive the lifting plate 312 and the ultraviolet pulse lamp tube 314 to descend. The lifting plate 312 can drive the connecting rod 311 at the end to rotate. The end of the connecting rod 311 can drive the sleeve rod 309 and the drive frame 308 to move. In turn, the drive frame 308 can drive the sliding column 306 and the semi-circular shell 301 to move. During the movement, the reset spring 307 drives the sliding column 306 to slide on the drive frame 308, so that the two semi-circular shells 301 maintain the inclined plane sliding with the inclined platform 315. When the two semi-circular shells 301 move out of the storage slot 103, the two semi-circular shells 301 are respectively located on both sides of the moving platform 101. Then, the user can place their mobile phone, watch, personal ID, etc. into the placement cavity 304. After that, the cylinder 313 can drive the lifting plate 312 to rise, thereby driving the drive frame 308 and the two semi-circular shells 301 to move back into the storage tank 103 through the connecting rod 311. At the same time, the ultraviolet pulse lamp tube 314 will rise to the center position of the two semi-circular shells 301. The ultraviolet pulse lamp tube 314 emits instantaneous strong light, which can perform pulse disinfection and sterilization on mobile phones and other items. The multiple reflective strips 303 on the inner wall of the semi-circular shell 301 can reflect the pulse strong light, thereby disinfecting the back of mobile phones and other items, improving the disinfection coverage. The pulse disinfection mechanism 300 can quickly disinfect multiple items. The reflection can ensure that the items are completely irradiated by the strong light, thereby improving the disinfection effect of personal items.
[0049] When disinfecting items such as mobile phones, the user needs to place their hand under the dispensing head 202. At this time, the infrared proximity sensor 105 detects the human hand and activates the servo motor 213 in the automatic dispensing mechanism 200. The output of the servo motor 213 drives the rotating shaft 212 and valve plate 214 to rotate 360 degrees, allowing the hand sanitizer in the fixed cylinder 201 to flow into the dispensing head 202. Simultaneously, the rotating shaft 212 drives the incomplete gear 215 to rotate one revolution, and the incomplete gear 215... During rotation, it can mesh with two racks 216, thereby driving the two racks 216 to rise and fall in opposite directions. The rising and falling of the racks 216 can cause the inclined column 217 and the roller 218 to collide, so that the roller 218 can roll on the inclined surface of the inclined column 217, thereby driving the two connecting frames 219 to move in opposite directions. The two connecting frames 219 can drive the two closed leak-proof covers 220 to separate, so that the disinfectant can flow out of the dispensing head 202 and fall onto the user's hands, allowing the user to rub their hands to disinfect. In the disinfection process, when the incomplete gear 215 rotates to a point where it no longer meshes with the rack 216, the compression spring 222 on the limit rod 221 compresses the two connecting frames 219 to move and reset. This causes the two leak-proof covers 220 to move closer together and close. The two leak-proof covers 220 not only prevent disinfectant from dripping and wasting, but also protect the dispensing head 202, preventing others from touching it and causing bacterial infection and cross-infection. This improves the overall hygiene of hospitals and other facilities. The automatic dispensing mechanism 200 allows the liquid in the storage tank 205 to flow into the fixed cylinder 201 first, and then the liquid is dispensed through the dispensing head 202. Therefore, there is no need to rely on hydraulic pumps and hoses to extract the liquid. Under the action of gravity, the liquid in the tank can flow out completely, thus making more complete use of the disinfectant and causing less waste. When the disinfectant in the storage tank 205 is gone, a certain amount of disinfectant can be temporarily stored in the fixed cylinder 201, so the hand sanitizer can continue to be used, which can increase the number of uses before adding disinfectant.
[0050] By simultaneously performing hand hygiene disinfection and personal item disinfection, the time required for the entire disinfection process can be reduced. After hand disinfection is completed, cylinder 313 descends again, causing the two semi-circular shells 301 to move out, making it easier for users to retrieve their items. This improves the efficiency of the device and allows users to complete personal hygiene cleaning in a shorter time.
[0051] When adding disinfectant, the storage tank 205 needs to be rotated, and then the abutting column 204 gradually moves away from the liquid adding column 208. Under the action of the return spring 210, the sealing block 209 is driven to block the two liquid outlet holes 207, thereby preventing disinfectant from dripping from the liquid outlet holes 207. Then, new disinfectant is poured into the funnel-shaped liquid adding column 208. This way, the inside of the device will not be contaminated due to liquid dripping when adding liquid.

6. A hand hygiene disinfection device based on face recognition according to claim 5, characterized in that, Multiple reflective strips (303) are fixedly connected in an annular shape at equal intervals on the arc-shaped inner wall of the semi-circular shell (301).
7. The method of using a hand sanitizing device based on facial recognition according to claim 6, characterized in that, It includes the following steps: Step 1: The camera (104) in the device can record facial information, so that when performing hand sanitizing, it can first recognize and verify personal information. After the verification is completed, the device starts the pulse disinfection mechanism (300). Step 2: The cylinder (313) drives the lifting plate (312) and the ultraviolet pulse lamp tube (314) to descend. The lifting plate (312) can drive the connecting rod (311) at the end to rotate. The end of the connecting rod (311) can drive the sleeve rod (309) and the drive frame (308) to move. Thus, the drive frame (308) can drive the sliding column (306) and the semi-circular shell (301) to move. During the movement, the reset spring 2 (307) drives the sliding column (306) to slide on the drive frame (308). Thus, the two semi-circular shells (301) maintain the inclined plane sliding with the inclined platform (315). When the two semi-circular shells (301) move out of the storage slot (103), the two semi-circular shells (301) are located on both sides of the moving platform (101). Then the user can put their mobile phone, watch and personal ID card into the placement cavity (304). Step 3: The cylinder (313) can drive the lifting plate (312) to rise, thereby driving the drive frame (308) and the two semi-circular shells (301) to move back into the storage tank (103) through the connecting rod (311). At the same time, the ultraviolet pulse lamp tube (314) will rise to the center position of the two semi-circular shells (301). The ultraviolet pulse lamp tube (314) emits instantaneous strong light, which can perform pulse disinfection and sterilization on the items. The multiple reflective strips (303) on the inner wall of the semi-circular shell (301) can reflect the pulse strong light, thereby disinfecting the reverse side of the items and improving the disinfection coverage. Multiple items can be quickly disinfected through the pulse disinfection mechanism (300). Step 4: The user needs to place their hand under the dispensing head (202). At this time, the infrared proximity sensor (105) can detect the human hand, and then the servo motor (213) in the automatic dispensing mechanism (200) will be activated. The output end of the servo motor (213) can drive the rotating shaft (212) and the valve plate (214) to rotate (360) degrees, so that the hand sanitizer in the fixed cylinder (201) can flow into the dispensing head (202). At the same time, the rotating shaft (212) drives the incomplete gear (215) to rotate one revolution. During the rotation of the incomplete gear (215) It can mesh with two racks (216), thereby driving the two racks (216) to rise and fall in opposite directions. The rise and fall of the racks (216) can cause the inclined column (217) and the roller (218) to collide, so that the roller (218) can roll on the inclined surface of the inclined column (217), thereby driving the two connecting frames (219) to move in opposite directions. The two connecting frames (219) can drive the two closed leak-proof covers (220) to separate, so that the liquid outlet (202) flows out disinfectant and falls onto the user's hands, so that the user can rub and disinfect their hands. Step 5: By simultaneously disinfecting hands and personal items, the time required for the entire disinfection process can be reduced. After hand disinfection is completed, the cylinder (313) descends again, causing the two semi-circular shells (301) to move out, making it easier for the user to retrieve their items, thereby improving the working efficiency of the device.
