The gear 502 is meshed with a rack 504, and the rack 504 is symmetrically arranged on the inner walls on both sides of the fixed shell 1 to control the up and down movement of the device body 2. When collecting information on a person's face, the camera 4 can shoot from the front to ensure the accuracy of people's information collection and avoid multiple verifications and verification failures.

[0031] Specifically, positioning slide grooves 7 are provided on both sides of the device body 2 , and the positioning slide grooves 7 are slidably connected with positioning slide bars 8 , which are provided on the inner wall of the fixed shell 1 .

[0032] Furthermore, the cleaning component 6 includes a cleaning chamber 601, which is arranged near the bottom of the inner cavity of the fixed shell 1. A curved tube 602 is provided at a position on the inner wall of the cleaning chamber 601 corresponding to the display screen 3. A nozzle 603 is provided on the curved tube 602. The curved tube 602 is connected to a liquid pump 604. The liquid pump 604 is connected to a liquid storage chamber 605 through a pipeline. Cleaning liquid is used to rinse the outer surfaces of the display screen 3 and the camera 4 to prevent dust and other dirt from affecting the use of the display screen 3 and the camera 4, and when leaving the cleaning chamber, the wiper 14 is used to scrape off water stains to facilitate the use of the display screen 3 and the camera 4.

[0033] Furthermore, a fixed box 9 is connected to the bottom of the fixed shell 1 , a partition 10 is provided in the fixed box 9 , and the liquid guide pump 604 and the liquid storage chamber 605 are respectively provided on both sides of the partition 10 .

[0038] Working principle and process: When installed, the device is fixed in a vertical state. When performing face recognition, the camera 4 on the device body 2 will track the face to control the start of the drive motor 503 of the lifting component 5, and then the gear 502 moves up and down on the rack 504 to control the height of the device body 2, so that the face is completely photographed by the camera 4 from the front, to ensure that there is no deviation in the face information collected by the camera 4, to avoid the deviation of the face information due to looking up or looking down, resulting in the failure of comparison. When the face recognition device is not in use, the lifting component 5 is used to control the device body 2 to descend to a clean position. In the cavity 601, the liquid pump 604 of the cleaning component 6 is started, and then the cleaning liquid in the liquid storage chamber 605 passes through the liquid pump 604 and the curved tube 602 and is sprayed out by the nozzle 603 to rinse the outer surface of the display screen 3 and the camera 4 to remove dust and other dirt attached thereto. When the lifting component 5 controls the device body 2 to move upward, the wiper plate 14 can scrape off the residual water stains on the display screen 3 and the camera 4. The cleaning liquid in the cleaning cavity 601 passes through the liquid pipe 11, and the dust and other dirt therein are filtered by the filter plate 12. The filtered cleaning liquid is re-introduced into the liquid storage chamber 605 for reuse.
