Notably, a wind pressure sensor is arranged in the cabinet body 1. Whether the filter cotton 32 is blocked or not can be judged according to the air flowing pressure in the cabinet body 1, so that the moving device 6 and the dust removing device 5 are automatically started, and further, the manual operation is avoided. It should be noted that, the wind pressure sensor 7 is connected with the dust suction fan 5122, the brush motor 5221 and the rotating motor 65 through the PLC controller, and the air pressure threshold value in the cabinet body 1 is preset through the PLC controller, when the air pressure sensor obtains that the air pressure in the cabinet body 1 is greater than the preset threshold value, the filter cotton 32 is blocked, the PLC controller can control the fresh air fan 4 to stop working, and simultaneously, the dust suction fan 5122, the brush motor 5221 and the rotating motor 65 are started to work. When the air pressure sensor 7 obtains that the air pressure in the cabinet body 1 is smaller than a preset threshold value, the PLC controller can control the dust suction fan 5122, the brush motor 5221 and the rotating motor 65 to stop working, and simultaneously control the fresh air fan 4 to continue working, so that normal ventilation and heat dissipation of the cabinet body 1 are ensured. And it should be understood by those skilled in the art that the PLC control of the dust suction fan 5122, the brush motor 5221 and the rotating motor 65 is performed in the prior art, and no improvement of the computer program is involved.
The working principle of the utility model is as follows:
when not carrying out clean function, dust collector 5 is inoperative, and fresh air fan 4 starts, inhales first cavity 11 through inlet opening 13 with the outside air of cabinet body 1, filters through the dust filter 3 in the cabinet body 1, and clean air after the filtration enters into in the second cavity 12, under the effect of fresh air fan 4, discharges from the air outlet 14 of cabinet body 1, enters into communication equipment inside to play the effect of cooling to communication equipment. When the dust filtering device 3 needs to be cleaned after being used for a period of time, the fresh air fan 4 is stopped to work, the dust removing device 5 is driven to reciprocate on the surface of the dust filtering device 3 through the moving device 6, the dust collecting component 512 can suck dust on the dust filtering device 3 into the dust collecting cavity 511 through the dust collecting opening 5111, the dust is discharged through the dust discharging opening 5112 and discharged out of the cabinet through the air inlet 13 under the action of the dust collecting component 512, meanwhile, the brush component 521 in the dust collecting opening 5111 can clean fine dust particles on the dust filtering device 3 under the driving of the rotating component 522, and therefore the dust collecting effect can be achieved while cleaning the dust particles adsorbed on the dust filtering device 3, and the self-cleaning function of the dust filtering device 3 can be achieved.
The foregoing description of the preferred embodiments of the utility model is not intended to be limiting, but rather is intended to cover all modifications, equivalents, alternatives, and improvements that fall within the spirit and scope of the utility model.
