Cabinet air-conditioner dust gauze self-cleaning device and operation method thereof

The invention discloses a cabinet-type air-conditioning strainer mesh self-cleaning device and the working methods, wherein the device consists of a suction nozzle mechanism and a strainer mesh mechanism; the strainer mesh mechanism is fixed outside the scroll casing of the air passage and consists of a strainer mesh and a strainer mesh frame; the suction nozzle mechanism is attached to the side of the strainer mesh facing outward, and consists of main body arranged on the strainer mesh and a suction nozzle arranged on the main body, wherein the main body is driven by a drive mechanism to slide between the left and the right sides of the strainer mesh along the track, and the suction nozzle is driven by another drive mechanism to slide between the top and bottom sides of the strainer mesh along the main body; the suction nozzle is provided with a dust absorption port and a brush, and is connected with the vacuum cleaner arranged in the air-conditioning through a connecting passage; the brush adjacent to the dust absorption port cleans the strainer mesh first, and then the connecting passage of the vacuum cleaner produces negative pressure high speed air flow by way of the suction nozzle, and the air flow keeps sucking the dust at the dust absorption port. The invention is characterized by reliable operation, low costs, wide ranged of dust absorption and good effect of dust cleaning.
