[0028] like Figures 1 to 6 As shown, the utility model provides an access control device, comprising: a base 1, an access control host 6, a camera 9 and a display screen 10 installed on the access control host 6, an adjustment mechanism for adjusting the height of the access control host 6, and a cleaning mechanism for cleaning dust from the camera 9;

[0029] The cleaning mechanism includes: a first mounting shell 7 fixedly mounted on the top of the access control host 6, a second mounting shell 8 fixedly mounted on one side of the first mounting shell 7, a cleaning component for cleaning dust on the surface of the camera 9, and a blowing component for blowing away dust on the surface of the camera 9; the cleaning component includes: a cleaning cylinder 26 for cleaning dust on the surface of the camera 9, and a driving unit for driving the cleaning cylinder 26 to operate.

[0030] The driving unit includes: a threaded rod 20 rotatably mounted on the side wall of the first mounting shell 7, a moving block 21 threadedly connected to the threaded rod 20, a guide rod 22 installed through the side wall of the moving block 21, both ends of the guide rod 22 are fixedly mounted on the inner wall of the first mounting shell 7, and the two guide rods 22 are set to limit the moving block 21, so as to avoid the moving block 21 rotating with the threaded rod 20 when moving, so that the moving block 21 moves linearly along the axial direction of the threaded rod 20, and two guide rods 22 are provided, so as to provide a uniform limiting effect on both sides of the moving block 21, so that the moving block 21 has higher stability when moving, a rotating rod 23 rotatably mounted on the side wall of the moving block 21, a linkage gear 24 fixedly mounted on the top of the rotating rod 23, a sleeve 25 sleeved on the outer edge of the rotating rod 23, and the outer A limit strip 27 is fixedly installed on the side edge, a limit groove is provided on the inner wall of the sleeve 25, the limit strip 27 slides in the inner cavity of the limit groove, a connecting block 28 is rotatably installed on the outer edge of the sleeve 25, a movable rod 29 is fixedly installed on the side wall of the connecting block 28, and a bull's eye ball 30 is rotatably installed at the other end of the movable rod 29, a guide groove is provided on the inner wall of the first mounting shell 7, the bull's eye ball 30 slides in the inner cavity of the guide groove, a rack 31 is fixedly installed on the inner wall of the first mounting shell 7 and meshes with the linkage gear 24, a motor 11 is fixedly installed on the inner wall of the second mounting shell 8, and a transmission member is fixedly installed on the power output shaft of the motor 11 and one end of the threaded rod 20, the transmission member includes: a connecting plate 12 respectively fixedly installed on one end of the threaded rod 20 and the power output shaft of the motor 11, and a connecting rod 13 fixedly installed on the side wall of the connecting plate 12.

[0031] When cleaning the dust on the surface of the camera 9, the connecting plate 12 can be driven to rotate by starting the motor 11, and the connecting plate 12 drives the connecting rod 13 to rotate, and the connecting rod 13 drives the connecting plate 12 at the other end to rotate, so that the threaded rod 20 can be driven to rotate, and the moving block 21 can be driven to move by the rotation of the threaded rod 20, so that the moving block 21 can move along the axial direction of the threaded rod 20, and the rotating rod 23 is driven to move by the moving block 21, and the linkage gear 24 and the sleeve 25 are driven to move by the rotating rod 23, and the cleaning cylinder 26 can be driven to move by the sleeve 25. When the sleeve 25 moves, the connecting block 28 can be driven to move, and the movable rod 29 is driven to move by the connecting block 28, and the bull's eye ball 30 is driven to slide in the inner cavity of the guide groove by the movable rod 29. The guide groove is composed of a lifting groove and a cleaning groove. When the cleaning cylinder 26 is in the initial position, the cleaning cylinder 26 is located in the inner cavity of the first mounting shell 7. At this time, the bull's eye ball 30 is located at the highest point of the lifting groove. When the motor 11 is started, the threaded rod 20 can be driven to rotate, thereby driving the cleaning cylinder 26 to move, so that the bull's eye ball 30 slides along the path of the lifting groove, that is, slides from high to low. When the bull's eye ball 30 slides to the lowest point of the lifting groove, the cleaning cylinder 26 moves to the outside of the first mounting shell 7. At this time, it is at the height for cleaning the camera 9, and then it can move along the cleaning groove. The cleaning groove is horizontally arranged. When the cleaning cylinder 26 moves along the cleaning groove path, it can pass the front side of the camera 9. Due to the setting of the brush on the surface of the cleaning cylinder 26, the dust on the surface of the camera 9 can be cleaned, thereby achieving the cleaning effect of the camera 9.

[0032] When the bull's eye ball 30 moves to the end of the cleaning groove, the motor 11 rotates in the direction, thereby driving the cleaning cylinder 26 to move in the opposite direction, that is, to move to the initial position. When the motor 11 rotates forward and reversely, it can drive the motor 11 to move back and forth along the axial direction of the threaded rod 20, thereby driving the cleaning cylinder 26 to move back and forth, thereby realizing reciprocating cleaning of the camera 9 and improving the cleaning effect.

[0033] Since the linkage gear 24 and the rack 31 are meshed with each other, the linkage gear 24 rotates during the axial movement of the threaded rod 20, and the rotating rod 23 is driven to rotate through the linkage gear 24, the limiting bar 27 is driven to rotate through the linkage gear 24, the sleeve 25 is driven to rotate through the limiting bar 27, and the cleaning tube 26 is driven to rotate through the sleeve 25, so that the cleaning tube 26 moves axially along the threaded rod 20 while rotating, so that the camera 9 can be cleaned more comprehensively, thereby further improving the cleaning effect of the camera 9.

[0034] When the camera 9 is cleaned, the cleaning cylinder 26 is reset to its initial position, that is, located in the inner cavity of the first mounting shell 7, thereby protecting the cleaning cylinder 26 and avoiding long-term exposure of the cleaning cylinder 26 to the outside world, which would cause the cleaning cylinder 26 to be exposed to wind and sun and reduce the service life. This improves the practicability of the device and also makes it difficult for external dust to adhere to the surface of the cleaning cylinder 26, thereby avoiding affecting the cleaning effect of the cleaning cylinder 26.

[0035] The blowing assembly includes: an air bag 17 fixedly mounted at the bottom of the inner cavity of the second mounting shell 8, a nozzle 18 plugged and mounted at the bottom end of the air bag 17, a linkage plate 16 fixedly mounted at the top of the air bag 17, a linkage rod 15 hingedly mounted on the top of the linkage plate 16, a connecting tube 14 fixedly mounted at the top of the linkage rod 15 and rotatably mounted on the outer edge of the connecting rod 13, a slide groove opened on the inner wall of the second mounting shell 8, and a slide bar 19 fixedly mounted on the side wall of the linkage plate 16 and sliding in the inner cavity of the slide groove.

[0036] When the motor 11 is started, the connecting plate 12 can be driven to rotate, and the connecting plate 12 can drive the connecting rod 13 to rotate, and the connecting tube 14 can be driven to rotate in a circle through the connecting rod 13. The connecting rod 15 can be driven to reciprocate up and down through the connecting tube 14, and the connecting plate 16 can be driven to reciprocate up and down through the connecting rod 15, and the airbag 17 can be squeezed or restored through the linkage plate 16. When the airbag 17 is squeezed, the air in the inner cavity of the airbag 17 can be discharged through the nozzle 18 and blown onto the surface of the camera 9, so that the dust on the surface of the camera 9 that has not been completely cleaned can be blown off, further improving the cleaning effect. When the airbag 17 is restored, the outside air enters the inner cavity of the airbag 17 through the nozzle 18, preparing for the next cleaning.

[0037] The cleaning mechanism also includes: a PLC controller electrically connected to the motor 11, and a timer electrically connected to the PLC controller.

[0038] The cleaning cycle and cleaning duration are set by the timer. When the cleaning cycle is reached, the PLC controller automatically starts the motor 11 to run, thereby driving the cleaning mechanism to clean the dust on the surface of the camera 9. When the set cleaning duration is reached, the PLC controller controls the motor 11 to stop running, so that the device does not require the user to clean the dust on the surface of the camera 9 by himself, thereby achieving the effect of regularly cleaning the dust on the camera 9 and improving the convenience of using the device.

[0039] Through the cleaning mechanism of the present application, the camera 9 can be double-cleaned, so that the cleaning of the camera 9 is comprehensive and thorough, the cleaning effect is improved, and the camera 9 can be cleaned of dust regularly without the need for manual cleaning by the user, making the device more convenient to use. It solves the problem that the existing community access control host 6 needs to clean the face recognition camera 9 after a period of use to prevent dust from accumulating on the camera 9 and affecting user use, and usually requires the user to clean it manually, which is inconvenient to use.

[0040] The adjustment mechanism includes: a fixed tube 2 fixedly installed on the top of the base 1, a movable tube 3 movably installed in the inner cavity of the fixed tube 2, an access control host 6 fixedly installed on the top of the movable tube 3, an electric telescopic rod 5 fixedly installed on the inner wall of the fixed tube 2 and the movable tube 3, and a switch 4 fixedly installed on the outside of the fixed tube 2.

[0041] During use, if children and special groups of people are encountered, and the height of the access control host 6 is too high and the face cannot be captured, the user only needs to press the switch 4, and the electric telescopic rod 5 will be shortened, thereby reducing the overall height of the fixed tube 2 and the movable tube 3, so that the height of the access control host 6 can be adjusted, so that the camera 9 can be aimed at the user's face for recognition. After the recognition is completed, the electric telescopic rod 5 automatically extends to the original height, making the device more user-friendly.

[0042] Working principle: When in use, by starting the motor 11, the cleaning component and the blowing component can be driven to run, so that the camera 9 can be double-cleaned, so that the cleaning of the camera 9 is comprehensive and thorough, and the cleaning effect is improved. It solves the problem that the existing community access control host 6 needs to clean the face recognition camera 9 after a period of use to prevent dust from accumulating on the camera 9 and affecting user use, and usually requires users to clean it manually, which is inconvenient to use.
