[0034] A wedge block 208 is fixedly connected to the peripheral side surface of the first stirring rod 203, and the stirring component 2 also includes two horizontal plates 209 fixedly connected to the inner peripheral side surface of the box body 1, and a support rod 210 that contacts the inclined surface of the wedge block 208 is fixedly connected to the bottom of the horizontal plate 209, and a first spur gear 211 is fixedly connected to the top of the first rotating shaft 201; the outer peripheral side surface of the box body 1 is symmetrically fixedly plugged with a spray component 3, and the spray component 3 includes a first conduit 301 that passes through and is fixedly inserted on the outer peripheral side surface of the box body 1, and the outer peripheral side surface of the first conduit 301 is hingedly connected to the second conduit 302, and the bottom end of the second conduit 302 is fixedly connected to the nozzle 303, and a hose 304 that is connected to the nozzle 303 is slidably inserted between the first conduit 301 and the second conduit 302.

[0035] The operation process of this embodiment is as follows: By controlling the rotation of the first spur gear 211, the first spur gear 211 drives the rotation of the first rotating shaft 201, and then drives the rotation of a plurality of first stirring rods 203 and second stirring rods 205. During the rotation of the plurality of first stirring rods 203 and second stirring rods 205, the wedge-shaped blocks 208 on the plurality of first stirring rods 203 are in contact with the abutting rods 210, and then drive the first stirring rods 203 to rotate towards the bottom of the box body 1, thereby driving the second stirring rods 205 connected by the swing rods 206 to rotate towards the bottom inside the box body 1 (at this time, the first spring 204 is stretched).

[0037] The operation process of this embodiment is as follows: Connect the two hoses 304 to deionized water externally. A pump body is provided in the deionized water, and the output end of the pump body is communicated with the hose 304. By controlling the two support plates 309 to move towards the first rotating shaft 201, the arc-shaped abutting plate 306 is driven by the push rod 305 to abut against the second conduit 302 that is close to it, and then drive the second conduit 302 and the nozzle 303 to rotate towards the first rotating shaft 201. Control the two support plates 309 to move away from the first rotating shaft 201. Under the self-weight of the second conduit 302 and the nozzle 303, the two nozzles 303 are driven to rotate away from the first rotating shaft 201, providing power for the reciprocating rotation of the two nozzles 303.

[0041] The operation process of this embodiment is as follows: When the third spur gear 406 rotates and meshes with the incomplete gear 507, the incomplete gear 507 is driven to rotate, and then the rotating rod 502 is driven to rotate. The rotating rod 502 drives the winding roller 508 and the turntable 503 to rotate.

During the process when the third spur gear 406 is not meshed with the incomplete gear 507, under the elastic force of the return spring 511, the moving rod 509 and the circular plate 512 are driven to move away from the winding roller 508, thereby driving the winding roller 508 to rotate in the reverse direction through the traction rope 513, further driving the rotating rod 502 and the turntable 503 to rotate in the reverse direction, realizing the reciprocating rotation of the turntable 503. Through the reciprocating rotation of the turntable 503, the turntable 503 drives the two connecting columns 504 to rotate reciprocally, and then drives the two fixing plates 506 to move towards each other or in opposite directions through the two pull rods 505, further driving the support plate 309 to move reciprocally, providing power for the moving rod of the support plate 309.
