In the initial state, the iron block 58 is positioned at the rightmost side and attracted by the magnet 59, the second control lever 54 is positioned at the rightmost side by the elastic force of the control spring 56, the second control lever 25 is positioned at the rightmost side, the stopper 53 and the slide plate 51 are positioned at the uppermost side by the elastic force of the first spring 49, the stopper 53 blocks the water pipe 31, the pressing block 45 is positioned at the leftmost side and the second spring 43 is pressed, the second cord 36 is in the tensioned state, the third spring 41 is in the tensioned state, and the floating lever 38 and the link lever 40 are positioned at the rearmost side by the tensile force of the second cord 36.

When cleaning work is needed, the filter screen 19 is placed on the bottom plate 20 and fixed between the upper brush 24 and the lower brush 24; then, the stop lever 53 is pressed, the stop lever 53 moves backwards, the extrusion block 45 is clamped into the notch 48 under the elastic force of the second spring 43, at the moment, the stop lever 53 is clamped by the extrusion block 45 and cannot move forwards, meanwhile, the extrusion block 45 moves rightwards to cause the second pull rope 36 to be further tensioned, and then the floating rod 38 moves backwards under the pulling force of the second pull rope 36 and blocks the water outlet 35; simultaneously, the stop lever 53 extrudes the extrusion switch 46, and the motor 18 is started; meanwhile, the through hole 52 is moved backwards and communicated with the water pipe 31, and then the water in the water pipe 31 is sprayed out through the nozzle 30 and washes the filter screen 19; when the motor 18 is started, the motor shaft 17 rotates and drives the seventh bevel gear 12 to rotate, further the eighth bevel gear 11 rotates and drives the sixth rotating shaft 28 to rotate, further the sliding shaft 63 drives the fifth rotating shaft 64 to rotate, further the sixth bevel gear 62 rotates and drives the fifth bevel gear 66 to rotate, further the right fourth rotating shaft 69 rotates, further the left fourth rotating shaft 69 is driven to synchronously rotate by the left and right transmission gears 71, further the left second gear 72 rotates and drives the first gear 73 to rotate, further the second rotating shaft 74 rotates and drives the first bevel gear 75 to rotate, meanwhile, due to the sliding friction force between the second rotating shaft 74 and the second gear box 84, further under the action of the friction force, the second gear box 84 rotates in the same direction as the second rotating shaft 74 but at a rotation speed less than that of the second rotating shaft 74, further a rotation speed difference exists between the first bevel gear box 75 and the second gear box 84, the first bevel gear 75 drives the second bevel gear 78 to rotate, the third rotating shaft 76 rotates and drives the fourth bevel gear 82 to rotate, the third bevel gear 81 rotates, the first rotating shaft 23 rotates, the brush 24 rotates and brushes the filter screen 19, meanwhile, the first gear box 80 rotates due to the rotation of the second gear box 84, the first rotating shaft 23 rotates by taking the spiral track 32 as a motion track, and meanwhile, the distance between the second gear box 84 and the first gear box 80 gradually changes along with the rotation; the combined motion of the brush 24 is therefore: axial rotary brushing and spiral brushing taking a spiral track as a motion track; when the distance between the second gear box 84 and the first gear box 80 gradually increases, it is indicated that the first rotating shaft 23 is rotating towards the edge of the spiral track 32, and when the first rotating shaft 23 is about to move to the end, the first gear box 80 will press the first control rod 26 to the left, and then the first control rod 26 moves to the left, and then the iron block 58 is pulled to the left by the pulling force of the first pulling rope 57, and once the iron block 58 passes through the middle line of the two magnets 59, the iron block 58 will be attracted by the left magnet 59 and move to the leftmost side, and at the same time the second control rod 25 moves to the leftmost side, and then the right second gear 72 engages with the first gear 73, and then the direction of rotation of the first gear 73 changes, and then the direction of rotation of the second gear box 84 changes, and then the first rotating shaft 23 will reverse along the spiral track 32, and then the distance between the second gear box 84 and the first gear box 80 gradually decreases, when the first rotating shaft 23 is about to move to the end, the first gear box 80 extrudes the second control rod 25 to the right side, then the second control rod 25 moves to the right and drives the connecting plate 61 to move to the right, further drives the iron block 58 to move through the center line of the two magnets 59 and move to the rightmost side under the suction force of the magnets 59, and at the moment, the first gear 73 is meshed with the second gear 72 on the left side again and changes the direction, so that the automatic circular brushing effect is realized; meanwhile, water sprayed from the nozzle 30 is gradually accumulated in the water storage tank 34, when the water level rises, the floating rod 38 gradually moves upwards under the action of buoyancy, the extrusion block 45 is pulled leftwards by the pulling force of the second pull rope 36 until the extrusion block 45 moves out of the notch 48, the blocking rod 53 moves to the foremost side under the elastic force of the first spring 49, at the moment, the motor 18 is turned off, the water pipe 31 is blocked, the extrusion block 45 is blocked by the blocking rod 53 and cannot move rightwards, the floating rod 38 is located at the initial position under the elastic force of the third spring 41, the floating rod 38 moves upwards to open the water outlet 35, and then the sewage in the water storage tank 34 is completely discharged from the water outlet 35, so that the effects of automatic shutdown and sewage discharge after the filter screen 19 is completely cleaned are achieved, and then the cleaned filter screen 19 is taken out.

The invention has the beneficial effects that: scrub through axial rotation and use the spiral track to scrub the compound motion realization to the comprehensive of filter screen as the movement track, use the water level in the aqua storage tank as time signal simultaneously, realize the automation of motor and shut down, the automatic drainage of closing water and aqua storage tank of water pipe, whole operation process only need press the pin can, use convenience and fast very, high efficiency, low in labor strength, can not the direct contact foul on the filter screen simultaneously, more health, the cleaning performance is good, and is worth promoting.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
