Specifically, the first end of the air passing pipe 4 is communicated with a part of the top wall of the sewage channel 12 forming a part of the bottom wall of the water tank 2, and the air passing pipe 4 is integrally positioned in the water tank 2, so that the problem of water leakage at the air passing pipe can be effectively prevented.
In this embodiment, the negative pressure cover 3 is formed separately from the water tank 2. Alternatively, in other embodiments, the negative pressure cover 3 may be formed integrally with the water tank 2.
In this embodiment, the liquid surface of the first trapway 13 is flush with the bottom wall of the tank 2. In other embodiments, the liquid level of the first trap 13 may be lower than the bottom wall of the water tank 2.
In this embodiment, the top surface 21 of the tank 2 is not higher than the top surface 111 of the urinal 11, and specifically, the top surface 21 of the tank 2 is flush with the top surface 111 of the urinal 11.
The working principle of the embodiment is as follows:
referring to fig. 2 and 3, at this time, the low water tank toilet is in an initial state, the water level in the water tank 2 is at a working water level, the water in the first trap 13 forms a first water seal, the water in the second trap 14 forms a second water seal, and the first cavity 15 is a sealed cavity due to the first water seal and the second water seal. The valve core 521 of the check valve 52 closes the water through hole 32 by the elastic force of the elastic member 522, so that the second chamber 31 is also a sealed chamber.
When the water tank 2 drains water, the water level in the water tank 2 drops, water in the negative pressure cover 3 is drained into the water tank 2 through the bottom opening of the negative pressure cover 3, then the water tank 2 is drained, in the process of the water level drop of the negative pressure cover 3, the second cavity 31 can form negative pressure, the negative pressure is conducted to the first cavity 15 through the air passing pipe 4, so that the sewage draining channel 13 can form siphon as soon as possible, the siphon strength is high, and the flushing performance of the low-water-tank toilet can be effectively improved. The check valve 52 always keeps closing the water through hole 32 during the water discharge of the water tank 2, thereby ensuring the stability of the negative pressure formed in the negative pressure cover 3.
Referring to fig. 4 and 5, when the water inlet valve starts to feed water into the water tank 2, the water in the water tank 2 enters the negative pressure hood 3 through the bottom opening of the negative pressure hood 3, and as the water level in the water tank 2 rises, the water level in the negative pressure hood 3 also rises, and the water presses the air in the negative pressure hood 3 to be discharged from the air through pipe 4 to the first cavity 15, and then discharged through the first trap 13 or the second trap 14. Meanwhile, the water inlet valve also supplies water to the water supply channel 51, the valve core 521 of the one-way valve 52 is driven by the water flow pressure of the water supply channel 51 to move upwards and open the water passing hole 32, the water flow further flows into the air passing pipe 4 from the water passing hole 32, the water flow of the air passing pipe 4 further flows to the second trap 14 to replenish water to the second trap 14, and the water storage height of the second trap 14 is ensured to be enough to form a second water seal. When the water inlet valve stops feeding water, the water feeding channel 51 stops water, and the valve core 521 of the one-way valve 52 automatically closes the water through hole 32 under the elastic force of the elastic member 522, thereby returning to the initial state shown in fig. 2 and 3.
In other embodiments, it can also be set as: the rivers that cross trachea 4 and flow into the first chamber 5111 body still flow to first trapway 13 to can carry out effective moisturizing to first trapway 13, when effectively avoiding the water in the first trapway 13 not enough, first cavity 15 can't form confined cavity, and leads to the problem that the supplementary washing function of negative pressure became invalid. In addition, since the air pipe 4 can replenish the first trap 13, other water replenishing structures (for example, a water replenishing waterway led out from the water inlet valve alone and replenishing the toilet through an overflow channel of the water tank) are not needed for replenishing the first trap 13, and other water replenishing structures can be omitted.
In other embodiments, the valve core 521 of the check valve 52 may automatically close the water through hole 32 under the elastic force of the elastic member 522, and the valve core 521 may automatically close the water through hole 32 under the action of its own gravity, specifically: the check valve 52 includes a valve core 521 fitted to the water through hole 32, and does not include an elastic member 522, and the valve core 521 moves upward by the water pressure of the water supply passage 51 and automatically falls down by its own weight to close the water through hole 32 when the water supply passage 51 stops water. So that the elastic member 522 can be omitted.
In other embodiments, the check valve 52 may not automatically reset under the action of elastic force or self gravity, but automatically reset to close the water through hole 32 under the negative pressure formed in the negative pressure cover 3, specifically: when water in the negative pressure cover 3 flows out of the negative pressure cover 3 to generate negative pressure in the negative pressure cover 3, the negative pressure drives the check valve 52 to close the water through hole 32.
In other embodiments, it can also be set as: the water supply channel 51 is hermetically arranged through the negative pressure cover 3, and the outlet of the water supply channel 51 is positioned above the top end opening 41 of the air passing pipe and corresponds to the top end opening 41 of the air passing pipe; alternatively, the outlet of the water feed passage 51 is inserted into the air duct 4. This also enables the water supply passage 51 to supply water to the air duct 4, and the structure is simpler because the check valve 52 is omitted.
