[0038] The first filter screen 16 and the second filter screen 17 in the filtering mechanism in the embodiment can move under the action of the driving mechanism. The moving process is that the driving motor 7 starts to drive the driving gear 8 to rotate, the driving gear 8 drives the upper double-sided rack 9 and the lower double-sided rack 10 engaged with the driving gear 8 to slide on the support frame 3 in the same direction or in the opposite direction, and drives the transmission gear and another set of upper and lower double-sided racks engaged with the transmission gear to slide on the support frame 3 at the same time. The two sets of upper double-sided racks 9 move, respectively drive the two upper moving gears 11 engaged with the upper double-sided racks 9 to move, the two upper moving gears 11 move, respectively drive the two upper single-sided racks 13 engaged with the upper moving gears 11 to slide on the support frame together, and the upper moving gears 11 also drive the convex sliding blocks 12 at the two ends of the first filter screen 16 to slide linearly on the two upper end sliding rails 6, respectively. The two sets of lower double-sided racks 10 move, respectively drive the two lower moving gears 19 engaged with the lower double-sided racks 10 to move, the two lower moving gears 19 move, respectively drive the two lower single-sided racks 18 engaged with the lower moving gears 19 to slide on the support frame 3 together, and the two lower moving gears 19 also drive the convex sliding blocks 12 at the two ends of the second filter screen 17 to slide linearly on the two lower end sliding rails 4, respectively. The moving directions of the first filter screen 16 and the second filter screen 17 are different, and the first filter screen 16 and the second filter screen 17 can work alternately. When the first filter screen 16 works, the first filter screen 16 is horizontally arranged above the filtrate tank 34, and the first filter screen 16 is located at the water outlet of the water pumping mechanism. The sewage pumped by the water pumping mechanism is filtered through the first filter screen 16, and the filtered water directly enters the filtrate tank 34. The second filter screen 17 is located in the arc-shaped or semicircular sliding groove of the lower end sliding rail 4, and is in a turnover state, vertically arranged between the two vertical frame bodies of the support frame 3, and can dump the waste residue on the filter screen into the second waste residue recycling tank 33. When the second filter screen 17 works, the second filter screen 17 is horizontally moved to above the filtrate tank 34 in a turnover state, and the first filter screen 16 is moved to the arc-shaped or semicircular sliding groove position at the end of the upper end sliding rail 6, and can be turned over by 90 degrees, and can dump the waste residue on the filter screen into the first waste residue recycling tank 32, so as to realize automatic switching of the filtering mechanism and intelligent filtering of different sewage.

[0039] The overturning processes of the two filter screens are the same. The overturning principle of the first filter screen 16 is described in detail. The driving motor 7 is started to drive the driving gear 8 to rotate, thereby driving the first filter screen 16 to move away from the water inlet end. When the first filter screen 16 moves to the arc-shaped or semicircular sliding groove position at the end of the upper end sliding rail 6, the upper moving gear 11 will not continue to move. At this time, the upper single-sided gear rack 13 moves to the position of the end block 14, and the end block 14 limits the movement of the upper single-sided gear rack 13. However, the driving gear 8 continues to rotate to drive the upper double-sided gear rack 9 to continue to move. Since the upper moving gear 11 and the upper single-sided gear rack 13 cannot continue to move, the upper double-sided gear rack 9 drives the upper moving gear 11 to rotate between the upper double-sided gear rack 9 and the upper single-sided gear rack 13, thereby driving the convex sliding block 12 on the first filter screen 16 to rotate in the arc-shaped or semicircular sliding groove at the end of the upper end sliding rail 6. The convex sliding block 12 rotates clockwise to drive the first filter screen 16 to overturn 90 degrees, so that the filter residue on the first filter screen 16 can be poured out.

By twisting the hand rotating seat 39, the hand rotating seat 39 drives the water outlet pipe 40 to rotate and changes the spraying angle. The hand rotating seat 39 is fixedly installed with a convex rod, the rotating seat 38 is fixedly provided with a clamping column, and the convex rod and the clamping column on the rotating seat 38 are matched. The water outlet pipe 40 is fixed at different angles through the matching of the convex rod and the clamping column on the rotating seat 38 and the hand rotating seat 39.

[0042] The working process of the utility model is as follows: in a normal state, the first filter screen 16 is in a working state, and the waste material is filtered by the first filter screen 16 and the second filter screen 17. Figure 1 and Figure 5As shown, the upper movable gear 11 is located at the rightmost end of the upper end slide rail 6, and the first filter screen 16 is horizontally arranged above the filtrate tank 34. The water drawn by the water pumping mechanism enters the first filter screen 16 through the control valve 30 for filtration, and the filtered water is collected in the filtrate tank 34. At this time, the lower movable gear 19 is located at the leftmost end of the lower end slide rail 4, i.e. in the semicircular or arc-shaped slide groove at the end of the lower end slide rail 4, and the second filter screen 17 is vertically arranged above the first waste recovery tank 32. When the filter residue on the first filter screen 16 needs to be cleaned, the control driving motor 7 is started to drive the driving gear 8 to rotate, thereby driving the first filter screen 16 to move away from the water inlet end. When the first filter screen 16 moves to the arc-shaped or semicircular slide groove position at the leftmost end of the upper end slide rail 6, the upper movable gear 11 will not continue to move. At this time, the upper single-sided rack 13 moves to the position of the stop block 14, and the stop block 14 limits the movement of the upper single-sided rack 13, but the driving gear 8 continues to rotate to drive the upper double-sided rack 9 to continue to move. Since the upper movable gear 11 and the upper single-sided rack 13 have already failed to continue to move, the upper double-sided rack 9 slides to drive the upper movable gear 11 to rotate between the upper double-sided rack 9 and the upper single-sided rack 13, thereby driving the convex slide block 12 on the first filter screen 16 to rotate in the arc-shaped or semicircular slide groove at the end of the upper end slide rail 6. The convex slide block 12 rotates clockwise to drive the first filter screen 16 to overturn by 90 degrees, so that the filter residue on the first filter screen 16 can be poured out. When the driving gear 8 rotates to drive the first filter screen 16 to move, the lower double-sided rack 10 is also driven to move. When the lower double-sided rack 10 moves, it drives the second filter screen 17 located in the arc-shaped or semicircular slide groove at the end of the lower end slide rail 4 to counterclockwise overturn by 90 degrees, so that it overturns to a horizontal state. Then, under the action of the lower movable gear 11, the second filter screen 17 moves together with the lower double-sided rack 10 towards the water outlet end. When the first filter screen 16 moves to the arc-shaped or semicircular slide groove at the end of the upper end slide rail 6, the second filter screen 17 is just moved to directly above the filtrate tank 34. Therefore, when the filter residue on the first filter screen 16 is cleaned, the filter screen is also replaced.
