[0025] Embodiment

[0026] Such as Figure 1 And Figure 2As shown in the figure, an explosion-proof access control device proposed by the present utility model includes: an explosion-proof housing 1, and the explosion-proof housing 1 is made of stainless steel, having good mechanical properties and corrosion resistance. An explosion-proof rear cover 2 is clamped at the rear side of the explosion-proof housing 1, and the explosion-proof housing 1 and the explosion-proof rear cover 2 are connected by a plurality of bolts, making the clamping more stable; a control button 3 and a display screen 4 arranged on the front surface of the explosion-proof housing 1, and a user can input a password or perform other operations through the control button 3 to start the verification process of the access control system. The display screen 4 is used to display relevant information to the user, such as whether the input password is correct, the working state of the access control system, and the current time and date, for faster feedback. A monitoring probe 5 is arranged above the display screen 4, and the monitoring probe 5 is embedded in the explosion-proof housing 1 and is used in combination with identification technologies such as face recognition and fingerprint recognition to verify the identity of personnel, improve the security of the access control system, and prevent unauthorized personnel from entering; and, an installation groove 6 is opened on the front surface of the explosion-proof housing 1. Grooves 7 are respectively opened on both sides of the inner wall of the installation groove 6, and the grooves 7 are symmetrically arranged. A fingerprint recognition panel 8 for fingerprint unlocking is arranged inside the installation groove 6; a cleaning component 9 for cleaning the fingerprint recognition panel 8 is located inside the installation groove 6, and the cleaning component 9 is located above the fingerprint recognition panel 8.

[0027] As Figures 2 to 4 shown, the cleaning component 9 includes a guide rod 91 fixedly arranged inside the groove 7. A guide sleeve 92 is slidably arranged on the outer wall of the guide rod 91. A fixing plate 93 is fixedly arranged between the guide sleeves 92 to guide the fixing plate 93 and make the sliding of the fixing plate 93 more stable. A brush plate 94 is fixedly arranged on one side of the fixing plate 93, and the brush plate 94 is in close contact with the upper surface of the fingerprint recognition panel 8. An electric push rod 95 is rotatably arranged on one side of the fixing plate 93 through a mounting seat. The upper end of the electric push rod 95 is rotatably arranged with a mounting plate 96 through a shaft rod, and the mounting plate 96 is fixedly connected to the inner wall of the installation groove 6, facilitating the wiping of fingerprints, dust or other impurities on the fingerprint recognition panel 8.

[0028] As Figure 3 and Figure 4 shown, a storage box 10 is fixedly arranged inside the installation groove 6 for storing cleaning water. A storage box 11 is fixedly arranged on one side of the fixing plate 93. A plurality of nozzles 12 are communicated with the lower side of the storage box 11 for evenly spraying the cleaning water in the storage box 10 on the fingerprint recognition panel 8. The storage box 11 is communicated with the storage box 10 through a connecting pipe. Two groups of fixing frames 13 are fixedly arranged on the lower side of the guide rod 91. An air cylinder 14 is fixedly arranged between the fixing frames 13 for applying pressure inside the storage box 10. The upper end of the air cylinder 14 is rotatably connected with a connecting rod 15, and one end of the connecting rod 15 is rotatably connected to the fixing plate 93. The lower end of the air cylinder 14 is communicated with the storage box 10 through a connecting pipe, which can improve the wiping effect.

[0029] Furthermore, a spring 16 is sleeved on the outer wall of the guide rod 91. One end of the spring 16 is fixedly connected to the inner wall of the groove 7, and the other end of the spring 16 is fixedly connected to the guide sleeve 92, which can improve the stability of the movement of the guide sleeve 92.

[0030] Secondly, a liquid adding pipe 17 is communicatively arranged on one side of the storage box 10, and the liquid adding pipe 17 penetrates through the explosion-proof shell 1, facilitating the addition of cleaning water into the storage box 10.

[0031] Furthermore, the length of the guide rod 91 clamped on the outer wall of the explosion-proof shell 1 is the same as the length of the pressing rod of the air cylinder 14. After the guide rod 91 moves to the bottom of the fingerprint recognition panel 8, the pressing rod of the air cylinder 14 can move to the bottom at the same time, so as to completely wipe the fingerprint recognition panel 8.

[0032] The working principle of this embodiment is as follows: an appropriate amount of cleaning water is added into the storage box 10 through the liquid adding pipe 17. When cleaning, the output end of the electric push rod 95 pushes the fixed plate 93 to move. The fixed plate 93 drives the guide sleeve 92 to slide on the outer wall of the guide rod 91. The fixed plate 93 also drives the brush plate 94 to move. By the movement of the guide sleeve 92 on the outer wall of the guide rod 91, the movement of the brush plate 94 is guided, so that the brush plate 94 stably wipes the fingerprint recognition panel 8. It can automatically wipe fingerprints, dust and other impurities on the fingerprint recognition panel 8. The clean surface enables the recognition device to read user information more clearly, reducing the situation of misrecognition or non-recognition caused by dirt, thus ensuring the stable operation and efficient management of the access control system.

[0033] During the movement of the fixed plate 93, the pressing rod of the air cylinder 14 is driven to press downwards through the linkage rod 15, so that the air cylinder 14 applies pressure to the inside of the storage box 10 through the connecting pipe. The cleaning water added into the storage box 10 flows into the storage box 11 through the connecting pipe and is sprayed on the surface of the fingerprint recognition panel 8 through the nozzle 12. After spraying, it is wiped by the brush plate 94, which can effectively remove the stains on the fingerprint recognition panel 8. At the same time, the cleaning water also contains disinfectant, which can kill bacteria and viruses on the surface of the access control device and protect the health of users.

[0034] The above specific embodiments are only several alternative embodiments of the present invention. Based on the technical solution of the present invention and the relevant inspirations of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
