Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0031] Reference Figure 1 - Figure 4, the utility model provides an embodiment: a camera with a cleaning function, including a camera housing 1, the camera housing 1 is provided with components for completing the camera function, for capturing and recording real-time video images to help monitor and manage specific areas, which is the existing technology. A lens 2 is provided on the front of the camera housing 1, and a baffle 3 is fixedly connected to the top of the camera housing 1, which can protect the camera housing 1. A driving mechanism is provided on the top of the baffle 3, and a turntable 5, a slider 7 and a transmission rod 8 are provided on the top of the baffle 3. A slide groove 6 that cooperates with the slider 7 is opened inside the turntable 5, and the cross-section of the rear half of the slider 7 is set to a square, so that the shapes of the slider 7 and the slide groove 6 are adapted.

[0032] Reference Figure 2 - Figure 4 The slider 7 is slidably mounted on the inner wall of the slide groove 6, and the sliding direction of the slider 7 is the radial direction of the turntable 5. The slider 7 is set as a dovetail block, and the slide groove 6 is set as a dovetail groove, so that the slider 7 will not fall off the surface of the turntable 5 when sliding inside the slide groove 6. A through groove 10 that cooperates with the slider 7 is opened inside the transmission rod 8. The cross-section of the front half of the slider 7 is set to be circular, and the outer wall of the slider 7 contacts the inner wall of the through groove 10. The circular diameter of the cross-section of the front half of the slider 7 is equal to the inner wall width of the through groove 10, so that when the turntable 5 rotates, the transmission rod 8 is driven to swing back and forth through the cooperation of the slider 7 and the through groove 10. The slider 7 is rotatably mounted on the inner wall of the baffle 3 through the pin 9, and the pin 9 is fixedly mounted on the middle surface of the transmission rod 8. A control mechanism is provided inside the slider 7, and a cleaning mechanism is provided at the bottom of the transmission rod 8.

[0033] Reference Figure 1 、 Figure 2 The driving mechanism includes a stepper motor 4, which is fixedly mounted on the top of the baffle 3. The stepper motor 4 can accurately control the rotation angle of its output shaft, and is convenient for adjusting the rotation speed and rotation angle of its output shaft. It can be adjusted accordingly according to different work requirements, thereby improving the accuracy of control. The front side of the output shaft of the stepper motor 4 is fixedly connected to the rear side of the turntable 5. A support seat 20 is provided at the bottom of the camera housing 1, so that the camera housing 1 can rotate above the support seat 20, increasing the viewing angle of the picture that can be captured. It is a prior art. A protective box 21 is fixedly connected to the top of the baffle 3, and the driving mechanism is located inside the protective box 21. A box cover is hinged on the front of the protective box 21, and a handle is provided on the front of the box cover. The protective box 21 is used to protect and isolate the internal equipment. The control mechanism inside the protective box 21 can be controlled by opening the box cover with the handle.

[0034] Reference Figure 3 、 Figure 4The control mechanism includes a control rod 11, which is slidably mounted on the inner wall of the slider 7. The sliding direction of the control rod 11 is forward and backward sliding. The circumferential surface of the control rod 11 is fixedly connected with a ring 12, and the ring 12 is elastically connected to the inner wall of the slider 7 through a spring 13. By setting the spring 13, an elastic force toward the rear side is applied to the ring 12 and the control rod 11. The spring 13 is sleeved on the outside of the control rod 11, and a circular hole 14 matching the control rod 11 is opened on the inner wall of the slide 6. The number of the circular holes 14 is set to be multiple, and the multiple circular holes 14 are arranged on the inner wall of the slide 6 at equal intervals in a straight line. The straight line where the multiple circular holes 14 are located passes through the center of the turntable 5. By inserting the control rod 11 into the circular holes 14 at different positions, the distance between the slider 7 and the center of the turntable 5 can be changed.

[0035] Reference Figure 2 、 Figure 3 、 Figure 5 The cleaning mechanism includes a cleaning brush 15, the rear side of the cleaning brush 15 is in contact with the surface of the lens 2, and a soft cleaning cloth is provided on the rear side of the cleaning brush 15, which can provide better protection when wiping the lens 2. When the cleaning brush 15 is not in use, the stepping motor 4 is operated to make the cleaning brush 15 swing to the leftmost or rightmost side of the lens 2 to avoid blocking the lens 2. The front of the cleaning brush 15 is fixedly connected with a mounting block 16, and the bottom of the transmission rod 8 is provided with a mounting groove 17 that cooperates with the mounting block 16. The mounting block 16 is fixedly connected to the mounting block 16 by a fastening bolt 18, which is convenient for disassembly. The shape of the mounting block 16 is set to be T-shaped, and a through hole 19 that cooperates with the fastening bolt 18 is provided on the right side of the transmission rod 8. The fastening bolt 18 passes through the inside of the through hole 19.

[0036] Working principle: When in use, the stepper motor 4 works to make the turntable 5 rotate, thereby driving the slider 7 on the surface of the turntable 5 to rotate around the central axis of the turntable 5. Through the cooperation of the slider 7 and the through slot 10, the transmission rod 8 swings back and forth around the central axis of the pin shaft 9. The swing of the transmission rod 8 drives the cleaning brush 15 at the bottom to swing left and right on the surface of the lens 2, thereby wiping and cleaning the dirt on the surface of the lens 2.

[0037] By pulling the control rod 11 forward, the control rod 11 is displaced, driving the ring 12 to overcome the elastic force of the spring 13 and displace forward, thereby disengaging the control rod 11 from the inside of the circular hole 14. Then, the control rod 11 and the slider 7 can be moved in the radial direction of the turntable 5, thereby changing the distance between the slider 7 and the center of the turntable 5, thereby changing the amplitude of the transmission rod 8 when it swings left and right, making it convenient to change the cleanable area of ​​the lens 2, thereby improving the control accuracy and having better applicability and cleaning effect.

[0038] When the cleaning brush 15 needs to be replaced after long-term use, the fastening bolt 18 is loosened and removed from the through hole 19, thereby releasing the fixed relationship between the mounting block 16 and the transmission rod 8. The mounting block 16 can be easily removed from the inside of the mounting groove 17, and the cleaning brush 15 can be cleaned and replaced to prevent the cleaning brush 15 from being too dirty and thus reducing the cleaning effect on the lens 2.

[0039] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
