[0002] A Chinese patent with announcement number CN220823144U discloses a monitoring device with a heat dissipation function, which includes a camera housing, a monitoring camera and a heat spreader. The bottom surface of the camera housing is provided with a plurality of heat dissipation holes. The monitoring camera is arranged in the camera housing, and the heat spreader cover is installed on the bottom surface of the camera housing.

[0003] The above-mentioned monitoring equipment with heat dissipation function is equipped with a heat spreader on the heat sink. The electronic components inside the monitoring camera will dissipate heat into the camera housing when working. The air in the camera housing contacts the heat spreader through the heat dissipation holes. The heat of the air in the camera housing can be quickly absorbed by the heat spreader and dissipated to the outside.

[0004] However, in actual use, since video surveillance equipment is generally installed outdoors, external dust accumulates on the surface of the heat spreader and the cooling fins, which will greatly reduce the heat dissipation capacity of the heat spreader and the cooling fins, thereby reducing the heat dissipation in the camera housing.

[0005] Therefore, a self-cleaning video monitoring device is proposed. Utility Model Content
