[0002] Audio decoders are divided into two categories: pure audio decoders and AV audio and video decoders. Existing high-definition audio and video decoders are generally iron or plastic shells connected to each other to form an installation shell, and a cooling fan is installed inside the shell. However, this shell structure is directly in contact with the outside air. When the cooling fan is running, the air flows to dissipate the heat of the circuit board. However, this structure will bring external dust into the inside of the shell and deposit on the circuit board, affecting the normal operation of the circuit board.

[0007] The heat dissipation unit comprises a mounting frame fixedly connected to the upper part of the housing of the audio and video decoder, and a heat dissipation fan runs through the upper part of the mounting frame;

[0008] The adjustable dust filter unit comprises a dust filter structure slidably arranged at the lower part of the mounting frame, and fixed frames are fixedly connected to both sides of the dust filter structure.

[0009] Furthermore, a mounting plate connected by bolts is fixedly connected to the fixing frame, a dust baffle is fixedly connected to the lower part of the mounting plate, and the dust baffle corresponds to the air inlet.

[0010] Furthermore, a cylinder seat is fixedly connected to the upper part of the housing of the audio and video decoder, a telescopic cylinder penetrates through the cylinder seat, and the output degree of the telescopic cylinder is fixedly connected to the dust baffle.

[0011] Furthermore, a water collection pool is fixedly connected to the side wall of the audio and video decoder housing, and a cleaning unit is provided on the water collection pool.

[0012] Furthermore, the cleaning unit includes a cleaning equipment frame fixedly connected to the upper part of the water collection pool, a motor passes through the cleaning equipment frame, and a cleaning brush cylinder rotatably arranged on the cleaning equipment frame is fixedly connected to the output end of the motor, and the cleaning brush cylinder cooperates with the dust filter structure.

[0013] Furthermore, a water storage tank is fixedly connected to the water collection pool, and a sprinkler head is fixedly connected to the lower part of the water storage tank.

[0014] The beneficial effects achieved by the utility model using the above structure are as follows:

[0015] 1. By setting up an easy-to-adjust dust-proof mechanism for use, automatic adjustment and cleaning are performed during dust removal, reducing the trouble of disassembly. At the same time, a baffle structure is added to prevent dust from entering during this process;
