[0055] As Figure 18 , 20As shown in Figure 25, a first through cavity communicating with the air storage cavity is provided at the top of the fourth movable slot, and a first push rod is provided in the first through cavity; an air outlet cavity is provided on the side wall of the first movable cavity, and a stopper 14071 cooperating with the air storage cavity is provided at the bottom of the first sealing plate 1407; a second connecting block 120 is provided at the bottom of the partition plate, a third connecting block 1201 is provided at the bottom of the second connecting block 120, a sixth movable slot communicating with the air storage cavity is provided on the third connecting block 1201, a retaining rod 1202 is provided in the sixth movable slot, and a fourth connecting spring 1203 is provided at one end of the retaining rod 1202; after the fourth connecting rod moves to one end of the second movable cavity, the first limiting block is staggered from the third through slot to fix the fourth connecting rod, thereby fixing the second connecting rod in the first movable slot, ensuring that the runner can contact the filter plate when rotating to generate vibration on the filter plate, and completing the cleaning of the surface of the filter plate; when the first limiting block moves upward and is staggered from the third through slot, the first push block pushes the first push rod upward, and the first push rod is inserted into the air storage cavity. When the first push plate moves to the bottom of the air storage cavity, the first push plate pushes the first push rod downward, the first push rod pushes the first limiting block downward, and the first limiting block moves to the bottom of the fourth movable slot. After the first limiting block and the third through slot are aligned, the second connecting rod moves outward from the first movable slot, and the runner disengages from the filter plate, completing the reset of the filter plate; when the first movable cavity and the second through slot are aligned, the stopper is in the air outlet cavity, and the stopper closes the air outlet cavity. The air in the air storage cavity enters the first movable cavity to push the first transmission rod downward, and the movement of the first transmission rod drives the runner to rotate. The first convex block impacts on the filter plate to clean the surface of the filter plate; when the first sealing plate closes the first movable cavity, the stopper moves into the first movable cavity along with the first sealing plate. At this time, the air outlet cavity is in an open state, and the air in the first movable cavity flows out from the air storage cavity, ensuring that the first transmission rod can automatically reset after the first sealing plate is reset, and avoiding the excessive air pressure in the first movable cavity from hindering the reset of the first transmission rod; when the first push plate moves downward to compress the air in the air storage cavity, part of the air enters the sixth movable slot, and the air pressure pushes the retaining rod out of the sixth movable slot. When the connecting plate drives the cloth bag to rotate, the cloth bag abuts against the retaining rod, and the retaining rod abuts against the side wall of the cloth bag to bend the middle part of the cloth bag, and the bottom of the cloth bag is lifted upward. After the retaining rod extends for a specified time and re-enters the sixth movable slot, the cloth bag automatically drops after losing contact, generating vibration on the cloth bag to clean the surface of the cloth bag, so that both the cloth bag and the filter plate can be directly cleaned during use, and avoiding excessive dust accumulation on the cloth bag and the filter plate, which increases the cleaning difficulty.

When the second push plate moves downward, the solenoid valve is in an open state, and the air in the cavity is directly squeezed into the sixth movable groove, and the stop rod extends out of the sixth movable groove. After the second push plate moves to the bottom of the cavity, the solenoid valve closes, the fourth through groove opens, and the fifth connecting rope pulls the second push plate to move back. At this time, the stop rod is in an extended state, providing resistance to the rotating cloth bag. When the second push plate moves to the top of the cavity, the second slider pushes the third push rod to move, the first connecting rope pulls the second transmission rod to move upward, the second transmission rod drives the first rotating shaft to rotate, the third sealing plate flips out of the second groove, and the air in the sixth movable groove is discharged from the air outlet hole. The air outlet hole is on the back of the filter plate, and when the air is discharged, it blows on the back of the filter plate, providing an auxiliary cleaning effect for the filter plate. After the air in the sixth movable groove is discharged, the stop rod moves into the sixth movable groove.
