[0003] At present, face recognition devices on the market are usually directly installed on the wall or other fixed locations. However, when using face recognition devices, it may be inconvenient to put away and dispose of face recognition devices when they are needed or after use.

The wall-mounted component of a face recognition device according to claim 7, characterized in that: The sleeve (64) is fixedly connected to a liquid inlet pipe (611), and both ends of the liquid inlet pipe (611) in the horizontal direction are provided with one-way valves. The liquid inlet pipe (611) is fixedly passed through the outside of the housing (1), and a closing cover (612) is threadedly connected to the liquid inlet pipe (611).

9. The wall-mounted component of a face recognition device according to claim 7, characterized in that: The mounting assembly (7) comprises a central rod (71) fixedly mounted on the back side of the housing (1); one end of the central rod (71) away from the housing (1) is rotatably connected to a cross-shaped plate (72); and a positioning hole (73) is formed on the cross-shaped plate (72).

10. A method for using a wall-mounted component of a face recognition device, applied to a wall-mounted component of a face recognition device according to any one of claims 1 to 9, characterized in that: The steps include: S1: The identification device body (2) is clamped and limited. The upper clamping plate (55) drives the square rod (54) to move upward, and the first spring (53) is stretched accordingly. The identification device body (2) is moved between the upper clamping plate (55) and the lower clamping plate (51) and positioned so that the gasket (56) is in close contact with the identification device body (2), thereby clamping and positioning the identification device body (2); S2: The cover (1) is positioned and installed. The cross-shaped plate (72) drives the center rod (71) to rotate and adjust. A threaded hole is drilled at a suitable position on the wall using a drilling machine. A bolt is passed through the positioning hole (73) and connected to the threaded hole on the wall, thereby installing the cover (1) on the wall. S3: When the identification device body (2) is used, the motor (31) is running, the shaft (32) drives the gear (33) to rotate, and the rack plate (34) moves downward accordingly. The angle adjustment component (4) drives the limit component (5) to move downward. The guide rod (35) and the side plate (36) increase the stability of the up and down movement of the identification device body (2), so that the identification device body (2) can be adjusted vertically up and down. After the identification device body (2) moves to the bottom of the cover (1), due to the existence of a certain friction force between the ball block (43) and the hexagonal plastic block (44), the angle of the lower card plate (51) is adjusted by the ball block (43) and the hexagonal plastic block (44), so that the identification device body (2) is adjusted to a suitable angle; S4: During the downward movement of the identification device body (2), the shaft (32) drives the eccentric wheel (65) to rotate, intermittently squeezing the arc plate (67), and the piston pressure plate (69) moves in a direction away from the arc plate (67). The piston pressure plate (69) moves to squeeze the cleaning liquid inside the liquid collecting box (61). The second spring (68) facilitates the resetting of the arc plate (67). The cleaning liquid inside the sleeve (64) is transmitted to the inside of the liquid collecting box (61) through the guide tube (610), and flows into the wiping cotton block (63) through the leakage hole (62), so that the wiping cotton block (63) is soaked. During the downward movement of the identification device body (2), the cleaning liquid is smeared on the liquid crystal screen of the identification device body (2), thereby facilitating the cleaning of the surface of the identification device body (2).
