Problems solved by technology

The previous structure would lead to a large space structure, and the anti-siphon CL line is too low, which will increase the space above the toilet surface. In addition, due to the mutual overflow of the small water tank, the mutual overflow can only be carried out by the water's own weight, and the mutual overflow ability is poor. would cause the overflow to leak to the external

Embodiment 1

[0023] A novel anti-siphon device for a flushing valve of the present invention, the flushing valve is provided with a water inlet 100, a water outlet, and a ventilation port 500 communicating with the outside air, and also includes a water inlet passage communicating with the water inlet 100, and two ends respectively connected to the water inlet passage and the water inlet passage. The water outlet passage communicated with the water outlet, and the breathable valve 2, the breathable valve 2 is arranged between the water inlet passage and the water outlet passage, and is perpendicular to the water inlet passage, and the breathable valve 2 has a valve for communicating or sealing the breather port 500 with the The sealing surface of the water outlet channel. When the vent valve leaks, the water will directly shoot into the water outlet channel on the other side. The anti-leakage power adopts the pressure of the water in the pipeline itself, and has strong anti-leakage ability....

Embodiment 2

[0027] refer to Figure 2 to Figure 5 , a novel anti-siphon device for a flushing valve according to the present invention. The flushing valve has a water inlet 100, a first water outlet 201, a second water outlet 202, and a vent 500 communicating with the outside air. It is characterized in that: the flushing valve It also includes two water inlet passages and two water outlet passages, the two water inlet passages include a first water inlet passage 301 and a second water inlet passage 302 arranged side by side, and the two water outlet passages include two ends connected to the first water inlet passage 301, The first water outlet passage 401 communicated with the first water outlet 201, and the second water outlet passage 402 whose two ends communicate with the second water inlet passage 302 and the second water outlet 202, the first water inlet passage 301 and the second water inlet passage 302 A vent valve 2 perpendicular to the water inlet passage is arranged between th...

Abstract

The invention provides a novel anti-siphon device for a flush valve, which is characterized in that the flush valve is provided with a water inlet, a water outlet and a ventilation port communicated with outside air, and further comprises a water inlet channel communicated with the water inlet, a water outlet channel with two ends respectively communicated with the water inlet channel and the water outlet, and a ventilation valve, the ventilation valve is arranged between the water inlet channel and the water outlet channel and is perpendicular to the water inlet channel, and the ventilation valve is provided with a sealing face used for communicating or sealing the ventilation opening and the water outlet channel. The anti-siphon device can achieve the anti-siphon purpose, and the problem of external leakage can be avoided when the breather valve leaks water.

Description

【Technical field】 [0001] The invention relates to the technical field of flush valves, in particular to a novel anti-siphon device for flush valves. 【Background technique】 [0002] In the prior art, the anti-siphon vacuum breaking structures of the toilet flushing valve are generally independent of each other and parallel to the water inlet passage. refer to figure 1 , there will be an independent vacuum breaking device in each water outlet channel of the flushing valve, and the vacuum breaking is parallel to the water inlet channel. There are sealing diaphragms at the front and back of the valve core a, and there are valve seats on the valve body corresponding to the sealing diaphragms. The front sealing diaphragm b1 of the core and the front valve seat c1 of the valve body form a one-way check function, and the rear sealing diaphragm b2 of the valve core and the rear valve seat c2 of the valve body form an external seal, which can be sealed or connected to the external ai...
