[0002] With the rapid development of real estate and security technology, door phones, as an important part of smart home and building intercom systems, the quality of door phones determines the quality of the entire system.

[0003] As an important part of the intelligent building intercom system, the door phone allows the homeowner to see the appearance of the person coming to the door downstairs through the display screen at home. The door phone collects external images through the internal camera. Since the door phone is installed outdoors, the cleanliness of the camera determines the clarity of the image. However, although the existing door phone can collect external images through the camera, it does not have the function of cleaning the camera, which causes external dust to adhere to the camera lens, thereby affecting the clarity of the image, and thus affecting the homeowner's ability to identify the appearance of the person coming downstairs. Therefore, it needs to be improved. Utility Model Content

[0037] As a technical optimization solution of the present invention, the operator can pull the pull plate 23 outward to drive the movable shaft 19 to move outward.

[0038] The working principle and use process of this utility model:

[0039] When the driving motor 6 is started, the threaded rod 7 will drive the two moving blocks 8 to move toward each other, so that the moving block 8 can push the mounting plate 10 to move downward through the hinged rod 9, and the mounting plate 10 will drive the limiting block 14 to move downward along the inner surface of the limiting groove 12 through the side plate 13, thereby limiting the mounting plate 10, and then the mounting plate 10 can drive the cleaning block 11 to move downward smoothly, so that the cleaning block 11 can clean the outer surface of the camera lens 2, thereby realizing the function of automatically cleaning the camera lens 2.

[0040] Since the spring 21 will pull the movable circular plate 20 inward under the action of elastic recovery, thereby driving the movable shaft 19 to move inward, and then the rotating plate 22 can press the movable plate 17 inward, thereby fixing the movable plate 17. When the operator needs to clean the dust entering through the sound hole 18, the pull plate 23 can be pulled outward, so that the pull plate 23 drives the movable shaft 19 to move outward, thereby causing the rotating plate 22 to move outward and disengage from the inside of the movable plate 17. Then the operator rotates the pull plate 23 again, so that the movable shaft 19 drives the rotating plate 22 to rotate, thereby releasing the fixing effect on the movable plate 17, and then the movable plate 17 can be disassembled, which is convenient for the operator to clean the dust.
