[0040] It is worth mentioning that the water power module 11 is the existing conventional technology, not described here, is composed of pipeline, water pump and valve, in use, through the water pump to make sewage flow into the sewage pipeline 12 inside.

[0041] The jet mechanism 4 comprises a plurality of nozzle sleeves 41, each of which is sleeved at the inner end of the communication pipe 31, and each of which is provided with an inclined surface 411 on the inner wall of the end thereof, each of which is movably sleeved with a secondary nozzle 42, each of which is provided with an outward convex surface 421 on the end surface thereof, and the nozzle sleeve 41 and the secondary nozzle 42 form a diffusion flow channel, the secondary nozzle 42 forms a straight flow channel, each of which is fixedly connected with an elastic hose 43, each of which is fixedly connected with a limiting rod 44 which is symmetrically arranged on the inner wall of the nozzle sleeve 41, and the end of the limiting rod 44 is provided with a first protrusion 441, each of which is fixedly connected with a limiting piece 45 in the groove on the surface thereof, each of which is provided with a rotating hole 451 on the surface thereof, and the first protrusion 441 is slidably connected in the limiting piece 45, each of which is rotatably sleeved with a movable ring 46, each of which is fixedly connected with a first tension spring 47, and the first tension spring 47 is fixedly connected with the secondary nozzle 42.

[0042] Specifically, when the first protrusion 441 is inserted into the limiting piece 45 away from the rotating hole 451, the secondary nozzle 42 cannot be rotated, so that the liquid medicine can uniformly flow in a diffusion manner; when the first protrusion 441 is inserted into the limiting piece 45 at the end of the rotating hole 451, the secondary nozzle 42 can be rotated according to the direction of the water flow, and the liquid medicine can flow in a straight flow manner, avoiding the waste of the liquid medicine caused by the reverse washing or dispersion of the water flow, so that the liquid medicine can be more smoothly mixed into the water flow, and the invalid diffusion of the liquid medicine in the sewage pipe 12 is reduced.
