the non-return blocking piece is rotatably arranged inside the middle section of the pipe body part and is configured to rotate to the opening state under the action of water flow inside the pipe body part and rotate to the closing state under the action of self gravity.
3. The drain of claim 2,
the pipe body part comprises a main pipe body connected with the water outlet and a connecting pipe body directly or indirectly connected with the main pipe body; the main pipe body is obliquely and downwardly extended from the water outlet to a connecting port of the main pipe body from front to back, and the connecting pipe body is bent and downwardly extended from the connecting port connected with the main pipe body from front to back; and is
The non-return blocking piece is arranged close to the connecting port of the main pipe body and/or the connecting pipe body.
4. The drain of claim 3,
the main pipe body and the connecting pipe body are connected through a pipe connector, and the main pipe body, the pipe connector and the connecting pipe body are sequentially sleeved together from inside to outside; and is provided with
The top of the rear end of the pipe connector is provided with a hook, and the top of the non-return blocking piece is rotatably hung on the hook.
5. The drainpipe of claim 4,
the hook is arranged on the rear end face of the pipe joint, and the rear end face of the pipe joint is inclined backwards from top to bottom so that the bottom of the non-return blocking piece abuts against the rear end face of the pipe joint when the non-return blocking piece is in the closed state.
6. The drain of claim 4,
the pipe joint is provided with an axially extending positioning groove, the main pipe body is provided with an axially extending strip-shaped positioning rib, and the strip-shaped positioning rib is inserted into the positioning groove so as to limit the position of the pipe joint relative to the main pipe body in the circumferential direction of the drain pipe; and is
The relative positions of the positioning groove and the hook are set to enable the hook to be positioned at the top of the rear end of the pipe connector after the pipe connector and the main pipe body are sleeved.
