Technical Field

[0001] This utility model relates to the field of fingerprint recognition technology, specifically a fingerprint recognition button cleaning device. Background Technology

[0002] Fingerprint recognition technology is widely used in various applications, such as smartphones, access control systems, and time attendance machines, due to its convenience, fast recognition, and stability. A fingerprint recognition button cleaning device is a specialized device designed to clean dirt and residue from fingerprint recognition modules.

[0003] The fingerprint recognition button cleaning device includes components such as a slide, a winding wheel, a cleaning plate, a steel wire rope, and cleaning cotton. When the device is triggered, the winding wheel rotates and pulls the steel wire rope, thereby driving the cleaning plate to wipe the surface of the fingerprint recognition module.

[0004] Existing fingerprint recognition button cleaning devices often use simple wiping or blowing methods, which are difficult to completely remove stains and residues from the surface of the fingerprint button. In particular, traditional cleaning methods are often ineffective for some stubborn stains, such as grease and sweat. Therefore, a fingerprint recognition button cleaning device is proposed to address the above problems. Utility Model Content

[0005] To overcome the shortcomings of existing technologies, some existing fingerprint recognition button cleaning devices often use simple wiping or blowing methods, which are difficult to completely remove stains and residues from the surface of fingerprint buttons. In particular, traditional cleaning methods are often ineffective for some stubborn stains, such as grease and sweat. This utility model proposes a fingerprint recognition button cleaning device.

[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: A fingerprint recognition button cleaning device of this utility model includes a fingerprint reader, a fingerprint button is provided on one side of the fingerprint reader surface, and grooves are formed on both sides of the fingerprint button on the fingerprint reader surface. A sliding rod is fixedly installed inside each groove, and a slider is slidably installed on each sliding rod. A protective shell is fixedly installed on the slider, and racks are provided on both sides of the protective shell and fixedly installed on the fingerprint reader surface. A dustproof plate is rotatably installed inside one end of the protective shell, and a spray pipe is provided on one side of the dustproof plate and fixedly installed inside the protective shell. Multiple nozzles are arrayed and fixedly installed on the spray pipe. A roller brush is mounted rotatably inside a protective housing on one side of the spray nozzle. The protective housing has a mounting groove, and a fixing seat is mounted slidably within this groove on one side of the roller brush. A cleaning sponge is fixedly installed at the bottom of the fixing seat. A water tank is fixedly installed inside the other end of the protective housing. A groove is formed on one side of the protective housing, and a connecting pipe is installed within this groove. One end of the connecting pipe is fixedly connected to the spray nozzle, and the other end is fixedly connected to the water tank. Through the cooperation of structures such as the sliding groove, sliding rod, sliding block, protective housing, dustproof plate, spray nozzle, roller brush, cleaning sponge, and water tank, comprehensive cleaning and protection of the fingerprint button is achieved, improving the accuracy of fingerprint recognition and extending the lifespan of the fingerprint reader.

[0007] Preferably, both sides of one end of the dustproof plate are fixedly connected to a rotating shaft, and a roller is rotatably mounted on the rotating shaft. The roller and the rack are located in the same plane. The cooperation between the roller and the rack reduces frictional resistance and improves the operating efficiency of the cleaning device. The presence of the roller also protects the rack, avoids wear caused by direct friction, and extends the service life of the equipment.

[0008] Preferably, both ends of the roller brush extend through the protective shell to the top of the rack and are fixedly mounted with gears. The teeth on the gears mesh with the grooves on the rack. Through the meshing of the gears and the rack, the roller brush can move precisely. When the rack moves, the gears will rotate accordingly, thereby driving the roller brush to perform cleaning work.

[0009] Preferably, a slide rail is provided on one side of the gear and fixedly mounted on the protective shell. A brake block is slidably installed in the slide rail near the gear. The brake block has teeth on the side near the gear. A limit rod is slidably installed in the other end of the slide rail. The limit rod is fixedly connected to the brake block. A spring is provided between the brake block and the other end of the slide rail and is sleeved on the limit rod. When it is necessary to stop the movement of the roller brush, the brake block will be pressed tightly against the gear under the action of the spring, and braking is achieved by the meshing of the teeth with the gear.

[0010] Preferably, a partition is fixedly installed in the center of the water tank. A cylinder is fixedly installed on one side of the partition, and a sliding plate is provided on the other side and slidably installed in the water tank. The piston rod of the cylinder is fixedly connected to the sliding plate. Through the cooperation of the cylinder and the sliding plate, the automatic spraying of cleaning liquid in the water tank is realized. When the piston rod of the cylinder extends, the sliding plate will push the cleaning liquid to the nozzle, thereby realizing the uniform spraying of the cleaning liquid.

[0011] Preferably, a water injection pipe is fixedly connected to one end of the outer side of the water tank, and a one-way valve is installed inside the water injection pipe. The installation of the water injection pipe and the one-way valve makes it more convenient to replenish the cleaning fluid. The presence of the one-way valve prevents the backflow of the cleaning fluid and ensures that the cleaning fluid in the water tank is always sufficient.

[0012] The advantages of this utility model are:

[0013] 1. This utility model, during the use of a fingerprint recognition button, after fingerprint recognition is completed, pushes the protective shell to move and cover the fingerprint button. At this time, the rotating shafts at both ends of the dustproof plate drive the rollers to rotate on the rack. Simultaneously, the rack drives the gear to drive the roller brush to rotate, activating the cylinder. Its piston rod pushes the slide plate to slide in the water tank, squeezing the cleaning liquid in the water tank through the connecting pipe into the spray pipe. The cleaning liquid is sprayed out from the nozzle, wetting the surface of the fingerprint button. The roller brush cleans the wet fingerprint button surface. At the same time, the protective shell, through the fixed seat, drives the cleaning sponge to absorb the cleaning liquid and impurities on the fingerprint button surface. This structural design achieves efficient and precise cleaning of the fingerprint button, solving the problem that some existing fingerprint recognition button cleaning devices often use simple wiping or blowing methods, which are difficult to completely remove stains and residues from the fingerprint button surface. Especially for some stubborn stains, such as grease and sweat stains, traditional cleaning methods are often inadequate. This improves cleaning efficiency and the service life of the equipment, while also improving the convenience and practicality of the equipment. Attached Figure Description

[0021] 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 of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0022] Please see Figure 1-5As shown, a fingerprint recognition button cleaning device includes a fingerprint reader 1. A fingerprint button 2 is provided on one side of the fingerprint reader 1. Slide grooves 3 are formed on the surface of the fingerprint reader 1 on both sides of the fingerprint button 2. Slide rods 4 are fixedly installed inside the slide grooves 3. Sliding sliders 5 are slidably installed on the slide rods 4. Protective shells 6 are fixedly installed on the sliding sliders 5. Toothed racks 7 are provided on both sides of the protective shells 6 and fixedly installed on the surface of the fingerprint reader 1. A dustproof plate 8 is rotatably installed inside one end of the protective shell 6. A spray pipe 11 is fixedly installed on one side of the dustproof plate 8. The nozzle 11 is installed inside the protective housing 6. Multiple nozzles 12 are fixedly mounted in an array on the nozzle 11. A roller brush 13 is rotatably mounted inside the protective housing 6 on one side of the nozzle 11. The protective housing 6 has a mounting groove. A fixing seat 15 is slidably mounted in the mounting groove on one side of the roller brush 13. A cleaning sponge 16 is fixedly mounted at the bottom of the fixing seat 15. A water tank 17 is fixedly mounted inside the other end of the protective housing 6. A groove 21 is formed inside one side of the protective housing 6. A connecting pipe 22 is installed in the groove 21, and one end of the connecting pipe 22 is fixedly connected to the nozzle 11. The other end is fixedly connected to the water tank 17. During operation, when the fingerprint recognition button is in use, the protective shell 6 is pulled to expose the fingerprint button 2 for fingerprint recognition. At this time, the protective shell 6 moves the dustproof plate 8, and at the same time moves the rotating shaft 9 and the roller 10. When the roller 10 contacts the rack 7, the rack 7 pushes the dustproof plate 8 to rotate through the roller 10, thus opening the dustproof plate 8. After the fingerprint recognition is completed, the protective shell 6 is pushed to move and cover the fingerprint button 2. At this time, the rotating shaft 9 at both ends of the dustproof plate 8 drives the roller 10 to rotate on the rack 7, and at the same time, the rack 7 drives the gear 14 to drive the roller 10 to rotate. When brush 13 rotates, cylinder 19 is activated. Its piston rod pushes slide plate 20 to slide inside water tank 17, squeezing the cleaning fluid in water tank 17 through connecting pipe 22 into spray pipe 11. The cleaning fluid is sprayed out from nozzle 12, wetting the surface of fingerprint button 2. Roller brush 13 cleans the wet surface of fingerprint button 2. At the same time, protective shell 6 drives cleaning sponge 16 through fixed seat 15 to absorb cleaning fluid and impurities on the surface of fingerprint button 2. When protective shell 6 completely covers fingerprint button 2, roller 10 disengages from rack 7 and drives dustproof plate 8 to rotate under the action of gravity, sealing protective shell 6.

[0023] Both sides of one end of the dustproof plate 8 are fixedly connected to a rotating shaft 9. A roller 10 is rotatably mounted on the rotating shaft 9. The roller 10 and the rack 7 are located in the same plane. During operation, when the fingerprint recognition button is in use, the moving protective shell 6 drives the dustproof plate 8 to move, and at the same time drives the rotating shaft 9 and the roller 10 to move. When the roller 10 contacts the rack 7, the rack 7 pushes the dustproof plate 8 to rotate through the roller 10, so that the dustproof plate 8 opens and prevents the dustproof plate 8 from contacting the fingerprint button 2 and causing damage.

[0024] Both ends of the roller brush 13 extend through the protective shell 6 to the top of the rack 7 and are fixedly mounted with gears 14. The teeth on the gears 14 mesh with the grooves on the rack 7. During operation, when the protective shell 6 moves along the slide bar 4 during the use of the fingerprint recognition button, the rack 7 drives the gears 14 to rotate, which in turn drives the roller brush 13 to rotate. The rotating bristles of the roller brush 13 contact the surface of the fingerprint button 2, effectively removing stains and residues through the brushing action, keeping the fingerprint button 2 clean.

[0025] A slide rail 25 is fixedly mounted on the protective shell 6 on one side of the gear 14. A brake block 26 is slidably mounted on the slide rail 25 near the gear 14. The brake block 26 has teeth on the side near the gear 14. A limit rod 27 is slidably mounted on the other end of the slide rail 25. The limit rod 27 is fixedly connected to the brake block 26. A spring 28 is provided between the brake block 26 and the other end of the slide rail 25 and is fitted onto the limit rod 27. During operation, when the fingerprint recognition button does not need cleaning, the spring 28 will push the brake block 26 to press against the gear 14. The meshing of the teeth with the gear 14 achieves braking, preventing the roller brush 13 from rotating on its own. When cleaning is required, external force will overcome the elasticity of the spring 28, causing the brake block 26 to disengage from the gear 14 and drive the limit rod 27 to slide within the slide rail 25, allowing the roller brush 13 to rotate for cleaning.

[0026] A partition 18 is fixedly installed in the center of the water tank 17. A cylinder 19 is fixedly installed on one side of the partition 18, and a sliding plate 20 is slidably installed in the water tank 17 on the other side. The piston rod of the cylinder 19 is fixedly connected to the sliding plate 20. During operation, when the fingerprint recognition button needs cleaning, the cylinder 19 receives a control signal and starts working. The piston rod of the cylinder 19 pushes the sliding plate 20 to move, squeezing the cleaning fluid in the water tank 17 through the connecting pipe 22 into the spray nozzle 11. The cleaning fluid is sprayed out from the nozzle 12, wetting the surface of the fingerprint button 2 and assisting the brushing action of the roller brush 13.

[0027] A water injection pipe 23 is fixedly connected to one end of the outer side of the water tank 17. A one-way valve 24 is installed inside the water injection pipe 23. During operation, when the cleaning fluid in the water tank 17 is insufficient during the use of the fingerprint recognition button, the cleaning fluid can be replenished into the water tank 17 through the water injection pipe 23. The design of the one-way valve 24 ensures that the cleaning fluid can only flow into the water tank 17 in one direction, preventing backflow and leakage of the cleaning fluid, and ensuring the stability and reliability of the cleaning device.

[0028] Working principle: During fingerprint recognition button use, pulling the protective cover 6 exposes the fingerprint button 2 for fingerprint recognition. At this time, the protective cover 6 moves the dustproof plate 8, simultaneously moving the rotating shaft 9 and roller 10. When the roller 10 contacts the rack 7, the rack 7 pushes the dustproof plate 8 to rotate via the roller 10, opening the dustproof plate 8. After fingerprint recognition is complete, pushing the protective cover 6 to cover the fingerprint button 2 causes the rotating shaft 9 at both ends of the dustproof plate 8 to rotate the roller 10 on the rack 7. Simultaneously, the rack 7 drives the gear 14 to rotate the brush 13. When the cylinder 19 is activated, its piston rod pushes the slide plate 20 to slide inside the water tank 17, squeezing the cleaning fluid in the water tank 17 through the connecting pipe 22 into the spray pipe 11. The cleaning fluid is sprayed out from the nozzle 12, wetting the surface of the fingerprint button 2. The roller brush 13 cleans the wet surface of the fingerprint button 2. At the same time, the protective shell 6 drives the cleaning sponge 16 through the fixing seat 15 to absorb the cleaning fluid and impurities on the surface of the fingerprint button 2. When the protective shell 6 completely covers the fingerprint button 2, the roller 10 disengages from the rack 7 and drives the dustproof plate 8 to rotate under the action of gravity, sealing the protective shell 6.
