[0023] Specifically, when the refrigeration unit 3 is working, external air enters into the interior of the outer cover 1 through the fan-shaped air intake grille 2. At this time, the fan-shaped filter screen 7 arranged at the fan-shaped air intake grille 2 removes dust from the air.

[0024] The cleaning mechanism 8 comprises a hollow cleaning plate 81 , and a brush roller 82 and an air blowing nozzle 83 are provided on the outer side surface of the hollow cleaning plate 81 .

[0025] Specifically, when the cleaning mechanism 8 is started, the stepper motor 9 drives the hollow cleaning plate 81 to swing left and right by forward and reverse rotation. At this time, the brush roller 82 rolls over the surface of the fan-shaped filter screen 7, and the dust on the outer surface of the fan-shaped filter screen 7 is vibrated and separated. Synchronously, the high-speed jet blown out by the blowing nozzle 83 blows away the dust covering the outer surface of the fan-shaped filter screen 7.

[0026] Furthermore, a heat dissipation fan 6 is installed at the left end of the outer side surface of the outer cover 1.

[0027] Specifically, the heat dissipation fan 6 is used to dissipate heat for the refrigeration unit 3 of the air conditioner.

[0028] Furthermore, the brush roller 82 is arranged closely against the fan-shaped filter screen 7 , and the air blowing nozzles 83 are linearly and evenly distributed on the outer side surface of the hollow cleaning plate 81 , and the air blowing nozzles 83 are arranged toward the fan-shaped filter screen 7 .

[0029] Specifically, the high-speed airflow blown out by the blowing nozzle 83 can be used to flush the fan-shaped filter screen 7 .

[0030] Furthermore, an air pump 13 is installed inside the outer cover 1, and the air inlet of the air pump 13 is connected to the air inlet window 4 through the air inlet channel 12, and the air outlet of the air pump 13 is connected to the hollow cleaning plate 81 through the air supply pipe.

[0031] Specifically, the air pump 13 can accelerate the gas and send it into the air blowing nozzle 83 for cleaning the fan-shaped filter screen 7.

[0032] Furthermore, a connecting nozzle 84 is provided at the end of the outer side surface of the hollow cleaning plate 81, and the connecting nozzle 84 is rotatably connected to the end of the air supply pipe.

The sealing cover plate 10 is sealed at the air intake window 4, and the end of the sealing cover plate 10 is rotatably connected to the inner side surface of the outer cover 1 via a hinge.

[0035] Specifically, the electrically controlled telescopic rod 11 can control the opening and closing of the sealing cover plate 10 . The sealing cover plate 10 will be opened only when the air pump 13 is started, so as to prevent external dust from entering the air inlet passage 12 as much as possible.

[0036] During use: when the refrigeration unit 3 is working, the heat dissipation fan 6 is started, and the external air enters the interior of the outer cover 1 through the fan-shaped air intake grille 2. Simultaneously, the air is filtered by the fan-shaped filter screen 7 arranged at the fan-shaped air intake grille 2. After the refrigeration unit 3 has been working for a period of time, the electrically controlled telescopic rod 11 contracts to open the sealing cover plate 10. At this time, the air pump 13 is started to send the high-pressure jet into the cleaning mechanism 8.

[0037] The stepper motor 9 is started to drive the hollow cleaning plate 81 to swing left and right. At this time, the brush roller 82 cleans the dust on the fan-shaped filter screen 7. At the same time, a high-speed jet is ejected through the blowing nozzle 83 to remove dust and blow the fan-shaped filter screen 7.
