[0024] As Figures 1 to 6 shown, a filter type air cooler includes a housing 1, and an air outlet member 2 and an atomizing air guiding member 3 which are arranged up and down at one outer end thereof. A waterproof plate 4 and a shielding plate 5 are vertically arranged at the lower end inside the housing 1. A filter screen 6 is arranged between the waterproof plate 4 and the shielding plate 5. An outer frame 7 is arranged on the outer wall of the filter screen 6. A motor 8 is arranged outside the housing 1. The output shaft of the motor 8 is connected to the outer frame 7 through a rotating rod 9.

[0025] A notch 11 for the filter screen 6 to extend into is formed on the shielding plate 5. A top plate 24 is arranged along the height direction of the shielding plate 5 at the notch 11. A scraping plate 15 is arranged at the upper end of the side of the top plate 24 away from the waterproof plate 4 and is slidably connected to the inner wall of the notch 11. The lower side of the scraping plate 15 is connected to the bottom side of the top plate 24 through a telescopic cover 13. A telescopic air hood 14 is vertically arranged inside the notch 11. The lower end of the telescopic air hood 14 is connected to the bottom side of the top plate 24, and its upper end is connected to the lower side of the scraping plate 15. An air pump 17 is arranged outside the housing 1. One end of the air pump 17 for pumping air is communicated with the inside of the telescopic air hood 14 through a delivery pipe 16.

[0026] The scraping plate 15 is arranged in a loop shape. The length and width dimensions of its inner wall are respectively smaller than the width and thickness dimensions of the outer frame 7. The purpose is to enable the hollow part of the scraping plate 15 to pass through the outer frame 7 located inside the notch 11. Cleaning brushes 21 are oppositely arranged on the left and right sides of the inner wall of the scraping plate 15. A telescopic water pipe 18 is arranged at the end of the lower side of the scraping plate 15 facing the notch 11. A number of spray heads 19 are communicated with the water pipe 18. One end of the water pipe 18 penetrates to the outside of the housing 1 and is communicated with the water delivery end of a water pump 20 outside the housing 1. A water absorption pad 22 is arranged on the outer wall of the scraping plate 15 on the side facing the inner wall of the notch 11. The purpose is to enable the scraping plate 15 to contact the inner wall of the notch 11 for water absorption cleaning when it slides.

[0027] An inclined return plate 10 is provided on the upper side of the waterproof plate 4. The inner wall length and width dimensions of the return plate 10 are each smaller than the length and height dimensions of the outer frame 7. And a return-shaped sealing strip 23 is embedded on the side of the return plate 10 facing the shielding plate 5. The purpose is that when the outer frame 7 is driven to move towards the waterproof plate 4, it can fit with the outer wall of the return plate 10 and press the sealing strip 23. On the left and right sides of the front end of the inner wall of the notch 11, water blocking strips 12 are oppositely arranged. The shortest distance between the two groups of water blocking strips 12 is greater than the length dimension of the outer frame 7, so that the outer frame 7 can enter and exit the notch 11 without interference. The length dimension of the telescopic cover 13 is greater than the length dimension of the outer frame 7 and also greater than the shortest distance between the two groups of water blocking strips 12. The water blocking strips 12 are provided to prevent part of the water from splashing out too much through the gap between the telescopic cover 13 and the inner wall of the notch when flushing the filter net 6.

[0028] When the filter net 6 starts to perform the filtering work, its front side fits with the rear side of the return plate 10, the sealing strip 23 is pressed, the motor 8 is in a power-off state, the gas in the telescopic air cover 14 is filled, and the scraper 15 is lifted to the upper end inside the notch 11. At this time, the air flow can pass through the filter net 6 for filtering.

[0029] When too many impurities on the filter net 6 affect the filtering work, at this time, the personnel temporarily stop the air flow transmission, and at the same time control the air pump 17 to pump air, so that the scraper 15 moves down as a whole. Then start the motor 8 to get electricity, and the motor 8 starts to control the rotating rod 9 to reverse, driving the filter net 6 to move away from the return plate 10 and enter the notch 11 inside the shielding plate 5, parallel to the shielding plate 5. Then start to control the air pump 17 to supply air, so that the telescopic air cover 14 starts to expand, pushing the scraper 15 to move up. The filter net 6 passes through the opening on the scraper 15 from bottom to top. At this time, the water pump 20 starts to work at the same time, so that the water spray head 19 starts to spray water, and the surface of the filter net 6 is flushed during the upward movement, and the impurities attached to the filter net 6 are washed down into the notch 11. After moving to the top, the air pump 17 pumps air again, so that the scraper 15 moves down again. During the downward movement, the water absorption pad 22 can clean one side of the inner wall of the notch 11 and absorb the impurities and water stains washed to one side of the inner wall of the notch 11.

[0030] In this embodiment, an impurity water pipe 18 (not shown in the drawing) communicating with the inside of the notch 11 can be provided at the lower end of the shielding plate 5, so as to prevent too much accumulation of impurities and cleaning water in the notch 11.

[0031] The above embodiments are descriptions of the present invention, not limitations on the present invention. Any scheme obtained by simply changing the present invention belongs to the protection scope of the present invention.
