[0035] See also Figure 5 An adjusting mechanism 3 is arranged inside the anti-return housing 1, and the adjusting mechanism 3 includes a screw rod 301. The outer surface of the screw rod 301 is rotatably connected to the anti-return housing 1, and a rotating handle is fixedly installed at one end of the screw rod 301, and the screw rod 301 can be rotated more conveniently through the handle.

[0036] The outer surface of the screw 301 is threadedly connected to the moving block 302, the outer surface of the moving block 302 is slidably connected to the non-return housing 1, and the top and bottom surfaces of the moving block 302 are fixedly installed with sealing rings, which can effectively prevent the fluid from overflowing from between the non-return housing 1 and the moving block 302.

[0038] The dual-control motor 209 in the present application is a common electrical device in the prior art. The present application will not elaborate on its model or internal structure, and it can also be replaced by other power sources.

[0039] Working principle: The pipe body 1 305 and the pipe body 2 306 are fixedly connected to the two water inlets of the anti-return housing 1 through the fixing parts. When the fluid flows from the pipe body 2 306 to the pipe body 1 305, the first output end of the dual-control motor 209 is turned on to rotate the active transmission rod 204, the active transmission rod 204 rotates to drive the chain 1 205, the chain 1 205 drives the driven transmission rod 206 to rotate, the driven transmission rod 206 rotates to drive the gear 207, the gear 207 rotates to drive the toothed plate 208 from the anti-return housing The slide plate 202 slides out from the inner wall of the shell 1 until the bottom surface of the tooth plate 208 slides to the top of the slide plate 202. When the fluid enters the inside of the non-return housing 1 from the tube body 2 306, the thrust of the fluid flow effectively causes the slide plate 202 to slide downward. The downward sliding of the slide plate 202 drives the spring 203 to deform until the slide plate 202 is pushed to the bottom of the non-return housing 1. The fluid can be discharged outward from the tube body 1 305. When the tube body 2 306 is closed so that the fluid is no longer transported, the slide plate 202 is no longer subjected to the pushing pressure. The spring 203 will push the slide plate 202 upward by its own resilience. When it is pushed to the bottom surface of the tooth plate 208, the tooth plate 208 will prevent it from sliding upward again, thereby effectively preventing the fluid from flowing back from the tube body 1 305 to the tube body 2 306. When the non-return direction of the fluid needs to be changed, the first output end of the dual-control motor 209 is turned on to make the tooth plate 208 slide into the inside of the non-return housing 1, and at the same time, the second output end of the dual-control motor 209 is turned on to make the other tooth plate 208 slide out of the non-return housing 1. , and slides out from the interior until the top surface of the other tooth plate 208 slides to the bottom surface of the slide plate 202. When the flow rate of tube body 1 305 and tube body 2 306 is adjusted as needed, the moving block 1 302 or the moving block 2 304 can be made to slide up and down in the inner wall of the non-return housing 1 by rotating the screw 1 301 or the screw 2 303 respectively, so that the two water inlets in the non-return housing 1 can be effectively blocked or opened, so that the flow rate of the fluid can be effectively and freely controlled, further making the device more flexible.
