Referring to fig. 1 to 4, an anti-siphon assembly 100 according to the present utility model is applied to a flushing system 200 of a toilet 1000, the anti-siphon assembly 100 includes a tube 10 and a sealing member 20, wherein a gas filling hole 13 penetrates through a wall of the tube 10; the sealing element 20 comprises a mounting seat 240 and an elastic sealing part 21 connected to the mounting seat 240, the mounting seat 240 is mounted at one end of the pipe body 10, the elastic sealing part 21 is located in the pipe body 10, the elastic sealing element 20 has a sealing state and a resetting state, the elastic sealing element 20 seals the air supplementing hole 13 in the sealing state, and the elastic sealing part 21 is spaced from the air supplementing hole 13 in the resetting state.

The pipe body 10 may be a metal pipe or a plastic pipe, and the shape of the pipe body 10 may be a straight pipe or a right-angle bent pipe, a U-shaped pipe, or the like, and the material and shape of the pipe body 10 are not particularly limited.

The manner in which the sealing member 20 is mounted on the pipe body 10 is various, for example, the sealing member 20 is provided with a threaded hole, the pipe body 10 is also provided with an assembly hole, and the screw member passes through the assembly hole and is matched with the threaded hole; for another example, the inner wall of the pipe body 10 is provided with an annular groove, and the sealing element 20 comprises an elastic snap ring which is clamped in the annular groove; the seal 20 may be completely installed in the pipe body 10, or only the elastic seal portion 21 may be located in the pipe body 10, and there are many ways in which the seal 20 is connected to the pipe body 10, which is not necessarily shown here.

The material of the elastic sealing portion 21 may be rubber, plastic, etc., the shape of the elastic sealing portion 21 may be a strip shape, a plate shape, etc., the elastic sealing portion is deformed when receiving a certain water flow impact force, so as to switch to a sealing state, when the inside of the pipe body 10 is not filled with water, the elastic sealing member 20 is reset, when the inside of the pipe body 10 is filled with water reversely from the water outlet end 12 to the water inlet end 11, the elastic sealing member 20 is deformed and far away from the air filling hole 13, therefore, when the water flow rate in the flushing system 200 is reduced, the flow is stopped or reversely flows, the elastic sealing member 20 is switched to a resetting state, and the air outside the pipe body 10 can flow into the pipe body 10 through the air filling hole 13, so as to avoid the siphon phenomenon.

The anti-siphon assembly 100 of the present utility model includes the pipe body 10 and the sealing member 20, and has a simple structure and low cost.

The end of the elastic arm 22, which is fixed to the pipe body 10, may be located on the side of the pipe body 10 away from the air supply hole 13 and away from the liquid inlet, or may be located on the same side of the air supply hole 13 in the pipe body 10 and close to the liquid inlet, and is not specifically limited herein.

There are various ways in which the elastic arm 22 seals the air supply hole 13, for example, one surface of the elastic arm 22 is attached to the end surface of the air supply hole 13; for another example, one surface of the elastic arm 22 is convexly provided with a conical plug, and the conical plug is plugged into the air supplementing hole 13; in some embodiments of the present utility model, a sealing ring 23 is protruding from a side of the elastic arm 22 facing the air-filling hole 13, and the sealing ring 23 is attached to an opening edge of the air-filling hole 13 when the elastic arm 22 is in a sealed state. The sealing effect is better like this to, have certain clearance between elastic arm 22 and the body 10 inner wall, when producing the siphon, the water flows in the body 10 against the current, flows in from the clearance between elastic arm 22 and the body 10 inner wall easily, makes elastic arm 22 receive the water pressure effect and resets easily, avoids elastic arm 22 and the end wall laminating absorption of air vent 13, and then leads to the unable problem of timely resetting of elastic arm 22.

The elastic arm 22 and the pipe body 10 are fixed relatively in various embodiments, and in some embodiments of the present utility model, one end of the elastic arm 22 is fixed to the inner wall of the pipe body 10 by means of clamping or riveting; in other embodiments of the present utility model, the mounting seat 240 is a mounting ring 24, the mounting ring 24 is detachable from one end of the pipe body 10, and one end of the elastic arm 22 is fixed to the inner side of the mounting ring 24.
