[0047] Meanwhile, the contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0048] The working principle of the present invention is as follows: a positive and a negative spiral coil is wound on the coil skeleton 21 to form an NS pole field, which acts on the NS pole field at both ends of the permanent magnet slot 33 on the intermediate mover. The NS pole field of the coil is changed by changing the direction of the current, so that the mover moves back and forth under the action of magnetic poles repelling each other and opposite magnetic poles attracting each other, thereby compressing and stretching the air in the cabin to form a vacuum, and under the action of the pressure difference with the external atmospheric pressure, water is sucked into the cabin and then discharged from the nozzle (the water pressure and flow rate can be adjusted by changing the current size and the time of switching between the positive and negative poles). When the direct-drive electromagnetic plunger water pump is working, water enters the protective cover 5 through the filter bucket 71, and then the water can enter the electromagnetic plunger water pump. The reciprocating motion of the mover can drive the connecting pipe 79 to move back and forth, thereby driving the crankshaft 72 to rotate through the swing arm 76, and then utilizing the meshing transmission between the first bevel gear 731 and the second bevel gear 734 to drive the vertical shaft 732 to rotate, thereby driving the first gear 735 to rotate, and utilizing the meshing transmission between the first gear 735 and the second gear 736 to drive the straight rod 733 to rotate, thereby driving the scraper 74 to rotate along the inner side of the filter bucket 71, thereby cleaning the impurities on the inner side of the filter bucket 71. Since the direct-drive electromagnetic plunger water pump generates negative pressure suction during operation, the negative pressure suction acts on the inside of the cross pipe 751 through the first filter plate 752, thereby forming an upward negative pressure suction between the connection between the cross pipe 751 and the filter bucket 71, so that the cleaned impurities are sucked by the negative pressure. Under the action of force, some impurities will enter the transverse tube 751 through the straight tube part of the filter bucket 71, and the straight rod 733 will also drive the cam 11 to rotate while rotating, so that the cam 11, L-shaped rod 12, pressure block 13, spring 14 and ring body 15 are used in combination to drive the connecting arm 753 to reciprocate, so that the impurities entering the transverse tube 751 will be pushed by the sliding rod 753, and when the sliding rod 753 moves, it drives the sliding cylinder 756 to move through the connecting arm 755, and then the sliding cylinder 756 will open the second filter plate 754, and then the sliding cylinder 756, the connecting arm 755 and the sliding rod 753 will support the second filter plate 754 in turn to keep the end of the transverse tube 751 in an open state, and then the sliding rod 753 will discharge the impurities out of the transverse tube 751, and reciprocate in turn, so that part of the impurities can be discharged each time.
