The directions of rotation of the two half gears 583 are also opposite. The upper half gear 583 first meshes with the first gear 581 and makes the first gear 581 rotate by 180 degrees, and then the meshing relationship is broken. At the same time, the lower first gear 581 meshes with the lower half gear 583. Then, the lower half gear 583 reversely rotates by 180 degrees, which drives the first gear 581 to reversely rotate by 180 degrees, and then the first gear 581 meshes with the upper half gear 583. Thus, the first gear 581 is driven to reciprocate by 180 degrees.

The output shaft of the motor 57 rotates, and then drives the lower rotating shaft 584 to rotate through the upper rotating shaft 584 and the two second gears 582. During this period, the directions of rotation of the two second gears 582 are opposite. At the same time, the directions of rotation of the two half gears 583 are also opposite. At the same time, the upper half gear 583 first meshes with the first gear 581 and makes the first gear 581 rotate by 180 degrees, and then the meshing relationship is broken.At the same time, the first gear 581 on the lower side will be in meshing relationship with the half gear 583 on the lower side, and then, as the half gear 583 on the lower side rotates reversely by one hundred and eighty degrees, the first gear 581 will rotate reversely by one hundred and eighty degrees, and then be in meshing relationship with the half gear 583 on the upper side, thereby driving the first gear 581 to rotate reciprocatingly by one hundred and eighty degrees, and further driving the driving rotating rod 51 to rotate reciprocatingly by one hundred and eighty degrees. In this process, the stirring rod 53 will be driven to rotate by the driving bevel gear 52 and the transmission bevel gear 54. It is worth noting that the stirring rod 53 will first rotate forwardly, and then rotate reversely, and then stir the upper side of the drainage pump 6 and the upper side of the water level sensor 7 through the stirring plate 55, stir the accumulated water, prevent the accumulated water from accumulating on the upper side of the drainage pump 6 and the upper side of the water level sensor 7, and ensure that they can operate normally.
