[0018] 1. In the utility model, the cleaning rod is driven by a motor to rotate, the top surface of the filter plate is cleaned and the dust is pushed outward, and then the collection box collects the dust. After the dust in the collection box is full, you only need to pull the collection box upwards to disassemble the collection box and pour out the dust inside through the discharge port, so as to achieve continuous cleaning of the filter plate and dust collection. The clean filter plate can more effectively filter impurities and dust in the air, ensuring that the air entering the water tank is purer. This helps to prevent dust and other particulate matter from accumulating inside the water tank, thereby maintaining the efficient operation of the water tank and related systems. At the same time, if dust and other particulate matter accumulate on the filter plate, it may reduce air flow and reduce air intake efficiency. Cleaning the filter plate can keep air circulation unobstructed and avoid performance degradation caused by blockage;

[0042] The working principle and use process of the utility model are as follows: when the water tank air intake assembly is used, first, when the air inside the water tank is output to the outside, the internal air supports the piston plate 28, and the piston plate 28 moves upward to fit with the bottom end of the movable sleeve 26, thereby closing the third vent hole 30, and at the same time, the piston plate 28 and the third vent hole 30 move upward at the same time, compressing the second spring 25, canceling the fit between the movable sleeve 26 and the fixed ring 21, so that the air can be transported out of the water tank through the gap between the movable sleeve 26 and the fixed ring 21 and the first vent hole 23, and when the air is transported to the inside of the water tank, the external air enters the limit cover 22 through the first vent hole 23 and the second vent hole 24, and then due to the movable The air at the top of the sleeve 26 moves downward, thereby squeezing the movable sleeve 26, causing the movable sleeve 26 to move downward and stretching the second spring 25. After that, the air inside the limit cover 22 continues to move inward due to the external atmospheric pressure, thereby pushing the piston plate 28 downward, thereby compressing the third spring 27 and moving it downward through the piston plate 28, so that air can enter the water tank. When the water level remains unchanged and air circulation is not required, the movable sleeve 26 is pushed downward through the second spring 25, and at the same time, the piston plate 28 is pushed upward through the third spring 27 to make the movable sleeve 26 fit with the fixed ring 21, and the piston plate 28 fits with the movable sleeve 26 to achieve sealing. Later, when the air exchange valve is maintained or replaced , it is only necessary to rotate the threaded sleeve 20, through the external thread inside the threaded sleeve 20 and the internal thread outside the top of the engaging sleeve 15, push the engaging sleeve 15 downward, and drive the limit ring 14 and the range extension chamber 16 downward at the same time through the engaging sleeve 15, thereby canceling the engagement of the limit ball 13, thereby canceling the engagement of the limit ball 13 with the card slot 19, so that the fixing tube 18 can be pulled out of the second fixing sleeve 12, and then the new fixing tube 18 is reinserted into the second fixing sleeve 12, and the threaded sleeve 20 is rotated in the opposite direction, through the external thread inside the threaded sleeve 20 and the internal thread outside the top of the engaging sleeve 15, push the engaging sleeve 15 upward, and drive the limit ring 14 and the range extension chamber 16 downward at the same time through the engaging sleeve 15. 4 and the range extension chamber 16 move upward, thereby squeezing the limit ball 13, forcing the limit ball 13 to move inward and engage with the card slot 19, thereby fixing the fixed pipe 18 and the valve at the top. At the same time, it is believed that the external air contains impurities such as dust, which enters the water tank and pollutes the water in the water tank, so that the air is filtered through the filter plate 10, and the cleaning rod 9 is driven by the motor 8 to rotate to clean the top surface of the filter plate 10. At the same time, the dust is pushed outward by the cleaning rod 9 and pushed into the collection box 4 through the receiving port 5.
