A motor is connected to a planet carrier 8 in the planetary gear train and is fixed on the frame 1.

The lower side plate of the water collecting tank 10 is funnel-shaped, and the water outlet is positioned at the lowest end of the water collecting tank 10.

It is worth noting that the water pump 11 in the invention can adopt various models, such as a diaphragm pump, a centrifugal pump, a single-screw pump and the like, wherein the water pumping speed of the water pump 11 is consistent with the normal water passing speed of the filter screen 6, and the water inlet speed is also controlled in the process; in order to prevent the upper end of the vertical cylinder 21 from bursting the bottom of the water collecting tank 10, a rubber skin layer is adhered to the upper end of the vertical cylinder 21; when the friction plate type water collecting tank is used, a part of water is accumulated in the water collecting tank 10, the water collecting tank 10 is positioned at the lowest end under the action of gravity, the lower end of the water collecting tank 10 is firmly supported by the plurality of vertical cylinders 21, and the friction plate 13 is in a separation state at the moment, namely a gap is reserved between the friction plate 13 and the friction disc 9; the lead of the spiral blade 5 in the device is gradually reduced from right to left, the spiral blade 5 can be extruded in the process of pushing the impurities from right to left, the sealing cover 23 at the left end of the discharging barrel 3 is closed when the impurities are small, and if the impurities are more, the impurities can be effectively discharged only after being extruded when passing through the discharging barrel 3; the spring connected to the slider 17 has a small elastic force, and the spring can restore the roller shaft 14.

Before use, in an initial state, the friction disc 9 and the friction plate 13 are tightly attached under the action of a pressure spring, when the water-saving water dispenser is used, a part of water is conveyed into the feeding box 2 firstly, so that the water collecting box 10 can move downwards under the action of the water and is contacted with the vertical cylinder 21, a gap is reserved between the friction plate 13 and the friction disc; the motor drives the planet carrier 8 to rotate, at the moment, the outer gear ring is in a no-load state, the sun gear 7 is fixed with the rotating shaft 4, the rotating shaft 4 is provided with the helical blade 5, and the helical blade 5 is in contact with the filter screen 6, so that the sun gear 7 has certain resistance, the rotating shaft 4 is kept in a non-rotating or basically non-rotating state, and the loss of the brush and the filter screen 6 is reduced; after a period of time, a part of meshes on the filter screen 6 are blocked by impurities, at the moment, the water pumping speed of the water pump 11 is unchanged, however, the water passing speed of the filter screen 6 is reduced, which results in the reduction of the water amount in the water collecting tank 10, the water collecting tank 10 moves upwards under the action of the pressure springs on the vertical rods 22 below, the water collecting tank 10 drives the friction plate 13 to move upwards through the U-shaped plate 12, the resistance of the outer gear ring is increased gradually along with the gradual upward movement of the friction plate 13, the planet carrier 8 still keeps rotating at the moment, the rotating shaft 4 starts to rotate gradually, the rotating shaft 4 rotates to drive the helical blade 5 to push impurities to the left, if the permeability of the filter screen 6 is restored at the moment, the water just accumulated in the upper feeding box 2 can rapidly pass through the filter screen 6 at the moment, the water collecting box 10 gradually descends to be in contact with the vertical cylinder 21, the resistance on the outer gear ring is gradually reduced at the moment and tends to idle, and meanwhile, the rotating speed of the rotating shaft 4 gradually descends.

If more impurity concentrates and appears and block up filter screen 6, the water yield in the header tank 10 reduces rapidly, header tank 10 moves upwards under the effect of a plurality of pressure springs, U-shaped plate 12 area friction plate 13 rebound, friction plate 13 is bigger and bigger to the pressure at friction disk 9 edge, when the second teeth of a cogwheel was meshed with the first teeth of a cogwheel, the outer ring gear was fixed, the motor drove planet carrier 8 and rotates this moment, sun gear 7 drove pivot 4 and rotates, pivot 4 transports impurity left through helical blade 5, impurity is extruded when the play feed cylinder 3 of process, moisture in it is discharged.

The invention has the outstanding advantages and remarkable progress that:

1. according to the invention, by utilizing the characteristics of the planetary gear and combining the specific situation of the invention, the planet carrier 8 is input, the rotating shaft 4 and the first friction disk 9 are output, when the permeability of the filter screen 6 is normal, the rotating shaft 4 has certain rotating resistance due to the action of the helical blade 5 and the brush on the helical blade 5, at the moment, a gap is formed between the friction disk 9 and the friction plate 13, and the outer gear ring idles, namely, under the condition that the permeability of the filter screen 6 is good, the helical blade 5 and the brush on the helical blade are not moved, so that the abrasion to the filter screen 6 can be greatly reduced, and the service lives of the filter screen 6, the; when filter screen 6 is blockked up by impurity, because the water in the header tank 10 reduces, header tank 10 drives friction plate 13 rebound through U-shaped plate 12, the rotational resistance that outer ring gear meets increases gradually, pivot 4 overcomes the resistance and slowly begins to rotate, when first teeth of a cogwheel and second teeth of a cogwheel meshing, outer ring gear is fixed this moment, planet carrier 8 drives pivot 4 through sun gear 7 and rotates, the clearance and the compression of filter screen 6 have been realized, after filter screen 6 cleans up, the water of intaking incasement overstocked pressure can be stayed rapidly and make header tank 10 rebound once more, until the separation between the friction disk 9 and the friction plate 13 of right-hand member.

2. According to the invention, the rotation resistance met by the outer gear ring is controlled by utilizing the up-and-down movement of the water collecting tank 10, so that the rotation or fixation of the rotating shaft 4 is controlled, unnecessary friction loss is reduced, and the maintenance period of the filter screen 6, the helical blade 5 and the hairbrush is prolonged.

3. According to the invention, by changing the diameter and the lead of the helical blade 5, moisture in impurities can be extruded out in the impurity removing process, solid-liquid separation is realized, and the sealing cover 23 at the left end is combined, so that the impurities can be effectively ensured to be discharged only after being compressed, and because the impurities move leftwards under the action of the helical blade 5 and gradually become compact, a sealed environment is formed, and the leakage of sewage from the discharge cylinder 3 can be prevented.

4. According to the invention, the roller shaft 14 with hard fibers rolls back and forth on the filter screen 6, so that the cleaning of the outside of the filter screen 6 is realized, the spring elasticity connected to the sliding block 17 is small and negligible relative to the rotation inertia of the incomplete gear 20 driven by the external gear ring during idle rotation, and when the pinion 18 is positioned at the toothless part of the incomplete gear 20, the roller shaft 14 can be restored to the original state under the action of the spring.

The filter screen 6 cleaning device is ingenious in structure, can ensure that the permeability of the filter screen 6 is in the optimal state, can timely compress and discharge impurities on the filter screen 6, reduces the loss of the filter screen 6 and the brush, prolongs the service cycle, cleans the two sides of the filter screen 6, and ensures the cleaning effect.
