An automatic cleaning method for an outdoor screen comprises the following steps:
A. in rainy days, the rain receiving plate 101 collects rainwater into the water tank 4, so that the rainwater can be conveniently recycled in the later period, and the screen can be cleaned;
B. controlling the water level inside the water tank: the floating plate 502 is always positioned above the liquid level in the water tank 4, when the liquid level in the water tank 4 moves upwards, the floating plate 502 pushes the first ejector rod 503 to move upwards and pushes the blocking plate 1022 to rotate until the blocking plate 1022 blocks the passage between the rain collecting plate 101 and the water collecting tank 102;
D. cleaning of the screen 2: the water pump 404 pumps water in the water tank 4 into the water pipe 405, the water is heated into steam by the heater 406, the driving device 9 drives the screen cleaning device 7 to move, the steam is sprayed on the surface of the screen 2 through the branch steam passage 704, the scraping plate 702 scrapes off stains on the surface of the screen 2, after the screen 2 is cleaned, the scraping plate 702 moves back and collides with the second ejector rod 1002, and as the friction force between the second sliding block 1001 and the friction slideway 105 is large, the second ejector rod 1002 drives the scraping plate 702 to rotate around the axis of the semicircular rotating block 705 to release the contact with the screen 2, so that the situation that the stains scraped from the screen 2 are again stained on the screen 2 in the process of moving back of the scraping plate 702 is effectively avoided.
The embodiments of the present invention have been described in detail with reference to the drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge of those skilled in the art without departing from the gist of the present invention.
