[0022] As a technical optimization solution of the utility model, Figure 3 and Figure 4 As shown, the axis of the sliding sleeve 506 and the rotation axis of the stirring rod 4 are on the same straight line, the cross-section of the water inlet pipe 501 is an L-shaped structure, the two connecting cylinders 503 are symmetrically distributed about the middle of the sliding sleeve 506, and the two connecting pipes 508 are symmetrically distributed about the middle of the rotating sleeve 507. Therefore, the rotating sleeve 507 can be driven to rotate by the stirring rod 4, so that the multiple nozzles 509 are rotated during the water spraying process, which effectively improves the cleaning effect.

[0023] As a technical optimization solution of the utility model, Figure 4 As shown, one end of the first spring 505 is fixedly connected to the top cover 2 , and the other end of the first spring 505 is fixedly connected to the sliding sleeve 506 , so that the sliding sleeve 506 can be reset under the action of the first spring 505 when cleaning is not required.

[0024] As a technical optimization solution of the utility model, Figure 1 As shown, three support legs 7 are fixedly connected to the hydrolysis reaction tank 1 , and the three support legs 7 are distributed in a circular array about the center of the hydrolysis reaction tank 1 , so that the hydrolysis reaction tank 1 can be supported by the three support legs 7 .
