After the use is finished, the trigger pressure plate 7 is manually pressed downwards, the trigger pressure plate 7 drives the telescopic outer sleeve 32 to move downwards, the telescopic outer sleeve 32 moves downwards and drives the fixing ring 28 to move downwards through the three fourth connecting rods 27, the fixing ring 28 drives the cleaning ring 25 to move downwards, dirt stuck on the filter holes 18 is scraped, and the filter holes 18 are prevented from being blocked due to the fact that the filter holes 18 are not cleaned after long-time use, and sewage is prevented from being discharged; when the trigger press plate 7 is pressed downwards, the trigger press plate 7 can drive the telescopic jacket 32 to move downwards, the telescopic jacket 32 moves downwards to drive the telescopic inner rod 36 to move downwards through the second spring 33, the telescopic inner rod 36 moves downwards to drive the drive plate 39 to move downwards, and because the lower end of the drive plate 39 is distributed in an inclined manner when the trigger press plate 7 is not initially moved downwards, the lower end of the drive plate 39 is deviated to one side of the drive wheel 48 when the drive plate 39 is driven to move downwards, and because the barbs 46 on the drive plate 39 are distributed in an inclined manner, the drive wheel 48 has certain rotation resistance, the drive plate 39 cannot drive the drive wheel 48 to rotate in the downward moving process of the drive plate 39, and in the state, the first spring 8 and the second spring 33 are compressed; after the trigger press plate 7 is released from being pressed downwards, the trigger press plate 7 moves upwards and returns under the action of the first spring 8, the trigger press plate 7 moves upwards to drive the telescopic jacket 32 to move upwards, when the telescopic jacket 32 moves upwards to the second spring 33 and is completely returned, the telescopic jacket 32 drives the telescopic inner rod 36 to move upwards, the telescopic inner rod 36 moves upwards to drive the drive plate 39 to move upwards, the barb 46 on the drive plate 39 is clamped in the notch 59 on the drive wheel 48, the drive plate 39 drives the drive wheel 48 to rotate under the action of the barb 46 and the notch 59, the drive wheel 48 rotates to drive the transmission rotating shaft 54 to rotate, the transmission rotating shaft 54 rotates to drive the second mounting plate 63 mounted on the transmission rotating shaft to rotate, and because the two shift levers 55 which are positioned at two sides of the drive plate 39 and are in close contact with the drive plate 39 are static relative to the drive plate 39 in the process that the drive plate 39 drives the drive wheel 48 to rotate, the two first mounting plates 61 arranged on the swing rod 56 are static, and at the moment, the second mounting plate 63 is driven to swing, so that the third spring 64 at the rear side of the swing direction of the second mounting plate 63 is pulled, and the third spring 64 is stretched; simultaneously, the rotation of the transmission rotating shaft 54 can drive the second gear 53 to rotate, the rotation of the second gear 53 drives the first gear 52 to rotate, the rotation of the first gear 52 drives the installation rotating shaft 49 to rotate, the rotation of the installation rotating shaft 49 drives the flexible shaft 47 to rotate, the flexible shaft 47 rotates to drive the swing plate 41 on the flexible shaft 47 to swing downwards, the original upward face of the swing plate 41 swings to the lower side, dirt accumulated on the original upward face of the swing plate 41 faces downwards, and the dirt drops into the collecting shell 13 under the action of gravity and is collected.

After the driving plate 39 moves upwards to be separated from the driving wheel 48, under the action of a third spring 64 stretched at the rear side of the second mounting plate 63 in the swinging direction, the first mounting plate 61 at the rear side swings towards one side of the second mounting plate 63 in the swinging direction, the first mounting plate 61 swings to drive the swing rod 56 to swing, the swing rod 56 drives the shift lever 55 to swing, and the shift lever 55 swings to drive the driving plate 39 to swing, so that the driving plate 39 swings to the other side and is kept under the action of the rotation resistance of the driving wheel 48; at this time, the driving plate 39 swings from the inclined state on one side to the inclined state on the other side; and the swing plate 41 is also swung in one direction.
