[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] 1. This integrated device, which combines face recognition, temperature measurement, and alcohol detection functions, works by starting a motor, which in turn drives a threaded rod to rotate. This threaded rod then moves an extension plate, which in turn moves a rack. The rack's movement causes a gear to rotate, which in turn rotates a rotating shaft. This rotating shaft then rotates a rotating cover, causing a nozzle at the bottom of the rotating cover to leak out and blow air onto the nozzle, thus detecting the alcohol content.

[0013] 2. This integrated device, which combines face recognition, temperature measurement, and alcohol detection functions, uses a pressure plate to move a squeezing block, causing the outer wall of the squeezing block to fit against the outer wall of the pressure block. This contact pushes the pressure block to both sides, causing it to move a push plate, which in turn moves a friction block. This causes the friction block to separate from the inner wall of the vertical plate, thus eliminating the fixed relationship between the lifting plate and the camera. At this point, the height of the lifting plate and the camera can be detected. Attached Figure Description

Detailed Implementation

[0020] 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 protection scope of the present utility model.

[0021] Please see Figure 1 - Figure 5 A device integrating face recognition, temperature measurement, and alcohol detection functions includes a base 1, a support frame 2 fixedly mounted on the top of the base 1, a main unit 3 fixedly mounted on the outer wall of the support frame 2, an extension base plate 4 fixedly mounted on the bottom of the main unit 3, a rotating cover 5 rotatably connected to the inner wall of the extension base plate 4, a motor 6 fixedly mounted on the outer wall of the extension base plate 4, a threaded rod 7 fixedly mounted on the output shaft of the motor 6, a rack 8 slidably connected to the inner wall of the extension base plate 4, an extension plate 9 fixedly mounted on the outer wall of the rack 8, and a gear 11 rotatably connected to the inner wall of the extension base plate 4. The inner wall of the gear 11 is fixedly mounted with... There is a rotating shaft 12, an air nozzle 13 is fixedly installed on the inner wall of the extension base plate 4, a vertical plate 14 is fixedly installed on the outer wall of the main unit 3, a lifting plate 15 is slidably connected to the outer wall of the vertical plate 14, a camera 10 is fixedly installed on the outer wall of the vertical plate 14, a squeezing block 17 and a pressure block 18 are slidably connected to the inner wall of the lifting plate 15 respectively, a push plate 19 is fixedly installed on the outer wall of the pressure block 18, a friction block 20 is fixedly installed on the outer wall of the push plate 19, a pressure plate 16 is fixedly installed on the outer wall of the squeezing block 17, a limit rod 22 is fixedly installed on the inner wall of the lifting plate 15, and a spring 21 is provided on the inner wall of the lifting plate 15.

[0022] In the above structure, the inner wall of the lifting plate 15 is adapted to the upright plate 14 so that the lifting plate 15 will not tilt when it moves up and down on the outer wall of the upright plate 14, thereby preventing the camera 10 on the outer wall of the lifting plate 15 from tilting.

[0023] In a preferred embodiment, the shape of the friction block 20 is adapted to the inner wall of the vertical plate 14, and the position of the friction block 20 corresponds to that of the inner wall of the vertical plate 14.

[0024] In the above structure, the spring 21 pushes the push plate 19, which in turn causes the push plate 19 to move the friction block 20 toward the inner wall of the vertical plate 14, so that the friction block 20 enters the interior of the vertical plate 14. Then, the friction between the friction block 20 and the inner wall of the vertical plate 14 fixes the position of the friction block 20, thereby fixing the position of the lifting plate 15.

[0025] In a preferred embodiment, the outer walls of both the extrusion block 17 and the pressure block 18 are inclined, and the outer walls of the extrusion block 17 and the pressure block 18 are parallel.

[0026] In the above structure, by pressing the pressure plate 16, the pressure plate 16 drives the pressing block 17 to move, thereby causing the outer wall of the pressing block 17 to fit against the outer wall of the pressure block 18. At this time, the fit between the pressure plate 16 and the pressure block 18 causes the pressure block 18 to be pushed to both sides, thereby causing the pressure block 18 to drive the push plate 19 to move, and causing the push plate 19 to drive the friction block 20 to move.

[0027] In a preferred embodiment: rack 8 is located at the bottom of gear 11 and meshes with gear 11, and the end of rotating shaft 12 away from gear 11 is connected to rotating cover 5.

[0028] In the above structure, the movement of the rack 8 causes the rack 8 to mesh with the gear 11, which in turn causes the gear 11 to rotate, which in turn causes the rotating shaft 12 to rotate, and the rotating shaft 12 to rotate the rotating cover 5.

[0029] In a preferred embodiment: the threaded rod 7 passes through the extension plate 9, and the threaded rod 7 and the extension plate 9 are threadedly connected, and the extension plate 9 is in contact with the inner wall of the extension base plate 4.

[0030] In the above structure, by starting the motor 6, the motor 6 drives the threaded rod 7 to rotate, and the threaded rod 7 drives the extension plate 9 to move through the threaded connection with the extension plate 9, which in turn drives the rack 8 to move.

[0031] In a preferred embodiment, the limiting rod 22 passes through the connection between the pressure block 18 and the push plate 19, and the connection between the limiting rod 22 and the pressure block 18 and the push plate 19 is a sliding connection.

[0032] In the above structure, the connection between the pressure block 18 and the push plate 19 is penetrated by the limiting rod 22, so that the connection between the pressure block 18 and the push plate 19 can only slide on the outer wall of the limiting rod 22 when moving, thereby limiting the pressure block 18 and the push plate 19 and preventing them from tilting when moving.

[0033] Working principle: When using the equipment, the pressure plate 16 is pressed, causing the pressure plate 16 to move the pressure block 17, which in turn makes the outer wall of the pressure block 17 fit against the outer wall of the pressure block 18. At this time, the fit between the pressure plate 16 and the pressure block 18 pushes the pressure block 18 to both sides, which in turn moves the push plate 19, which in turn moves the friction block 20, causing the friction block 20 to separate from the inner wall of the vertical plate 14. This causes the fixed relationship between the lifting plate 15 and the camera 10 to disappear. At this time, the height of the lifting plate 15 and the camera 10 is adjusted. After adjustment, the pressure plate 16 is released, and the elasticity of the spring 21 resets the structure, allowing the friction block 20 to re-fit against the inner wall of the vertical plate 14. The new bonding fixes the position of the camera 10. At this time, the camera 10 detects the user's face and body temperature. After the detection is completed, the motor 6 starts, which drives the threaded rod 7 to rotate. The threaded rod 7 moves the extension plate 9 through the threaded connection with the extension plate 9. The extension plate 9 then moves the rack 8. The movement of the rack 8 causes the rack 8 to mesh with the gear 11, which in turn causes the gear 11 to rotate. The gear 11 then rotates the rotating shaft 12, which in turn causes the rotating cover 5 to rotate. This causes the air nozzle 13 at the bottom of the rotating cover 5 to be exposed, and air is blown onto the air nozzle 13 to detect the alcohol content.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
