Toilets can be classified into two major categories, namely, cistern-type and cistern-free, according to the source of the flushing water. Most of the toilets having a water tank are flushed by water stored in the water tank, and most of the toilets having no water tank are directly communicated with a tap water pipe, and are flushed by the pressure of the tap water.
The urinal of the water tank-free closestool is communicated with a flushing valve for controlling the on-off of water flow through a drainage pipeline. When the toilet starts to be flushed, the flushing valve is opened, water mixed with residual air in the drainage pipeline rapidly flows out of the drainage pipeline and is sprayed out through a spray hole in the toilet bowl of the toilet, and the air is compressed and expands with moisture to generate sonic boom. Particularly, when the jet hole is located under the water seal of the toilet bowl and the diameter of the jet hole is small, if a relatively large amount of air is mixed in the water flow due to a relatively rapid water flow, the water flow jetted from the jet hole generates a relatively large noise at the jet hole.

It will be appreciated that the drain line 20 may also be provided separately from the flush valve 3 and not form an integral structure. The main flushing channel 4 of this embodiment is made of a hose, and the bottom water outlet end of the drainage pipeline 20 is connected with the water inlet end of the main flushing channel 4 through a screw thread. In other embodiments, the main flushing channel 4 may also be integrally formed in the toilet seat 1, and the drainage pipeline 20 includes a first pipe section (not shown) made of a hard material and a second pipe section (not shown) made of a soft material, the first pipe section and the flushing valve 3 form an integral structure, and the second pipe section is communicated with the main flushing channel 4 in the toilet seat 1, which is also feasible.

The exhaust pipe 30 is sleeved in the drainage pipe 20, the overflow channel 23 is formed between the outer wall of the exhaust pipe 30 and the inner wall of the drainage pipe 20, when water flows to the overflow channel 23, the air in the overflow channel 23 is pressed, and the air is partially or completely discharged from the exhaust pipe 30, generally, when the water flows to the drainage pipe 20, the air in the drainage pipe 20 is mostly discharged from the exhaust pipe 30, and a small part of the air may be discharged from the water outlet end of the drainage pipe 20 to the main water flushing channel 4 and finally discharged to the toilet bowl 2.

Furthermore, a check valve 50 is further disposed on the exhaust duct 30, and the check valve 50 is disposed between the exhaust cavity 31 and the exhaust duct 30. The check valve 50 normally opens the first vent hole 32 for the gas in the drain pipe 20 to be discharged, and the check valve 50 closes the first vent hole 32 under the pressure of the water flow and/or the air flow to prevent the water in the drain pipe 20 from leaking out of the exhaust pipe 30.
In this embodiment, a flow guide mechanism 40 is further disposed in the flow passage 23, and the flow guide mechanism 40 guides the flow in the flow passage 23, so that the flow stabilizing effect of the flow is better, and the exhaust can be smoother. The diversion mechanism 40 comprises a plurality of diversion ribs 41 extending along the axial direction of the drainage pipeline 20, the diversion ribs 41 are circumferentially arranged at intervals and divide the overflowing channel 23 into a plurality of relatively independent runners 42, and diversion is performed on water flow in each runner 42, so that the water flow is divided and guided, air in each runner 42 cannot move mutually, and the exhaust effect is better. In this embodiment, the flow guiding ribs 41 are fixedly connected to the outer wall of the exhaust duct 30, and certainly, the flow guiding ribs 41 may also be fixedly connected to the inner wall of the exhaust duct 20, or the flow guiding ribs 41 may be installed in the flow passage 23 after being independently formed. The arrangement of the diversion mechanism 40 can make the gas in the drainage pipeline 20 be discharged more quickly, and further reduce the noise of the drainage pipeline 20.
In this embodiment, the drainage pipeline 20 is communicated with the water outlet channel 12, and an anti-siphon mechanism is disposed on the water outlet channel 12. Preferably, the water outlet channel 12 and the water discharge pipeline 20 are longitudinally arranged in parallel, and the top of the water outlet channel 12 is communicated with the top of the water discharge pipeline 20 through a water passing cavity 70. Anti-siphon mechanism is including the intercommunication cross water cavity 70 and external second vent 71 and with second vent 71 matched with anti-siphon seat 60, cross in the water cavity 70 be equipped with second vent 71 matched with anti-siphon seat 60, during exhalant canal 12 did not go out water, anti-siphon seat 60 falls and opens under the action of gravity second vent 71, during the outside air can get into exhalant canal 12 via second vent 71 to prevent that siphonage from producing. When the water outlet channel 12 is discharging water, the anti-siphon seat 60 moves upward under the pressure of the water flow in the water outlet channel 12 and closes the second vent hole 71, so as to prevent the water flow in the water outlet channel 12 from flowing out from the second vent hole 71.
The flush valve 3 of this embodiment employs a solenoid valve whose water inlet passage 11 communicates with the water supply pipe 6. The drainage pipe 20 is connected to the main flushing pipe 4 of the toilet to supply water to the jet holes at the bottom of the toilet bowl 2, when the drainage pipe 20 is not discharging water, the main flushing pipe 4 has a water storage surface which is flush with the water sealing surface of the toilet bowl 2, and a space is arranged between the bottom end of the exhaust pipe 30 and the water storage surface. Preferably, the distance of separation is 10mm to 90 mm. Of course, the water storage surface flush with the water sealing surface of the toilet bowl 2 may be provided to rise into the drain pipe 20 as long as there is a space between the bottom end of the exhaust pipe 30 and the water storage surface, or the exhaust pipe 30 may be provided with a vent hole communicating with the drain pipe 20, thus maintaining communication between the exhaust pipe 30 and the overflow passage 23.
As shown in fig. 5 to 7, when the solenoid valve is operated to supply water, the water flows into the water inlet channel 11 from the water supply pipe 6, flows into the water outlet channel 12 through the valve core of the opened flush valve 3, the water flow of the water outlet channel 12 pushes the anti-siphon seat 60 upward, and a small part of the air in the water outlet channel 12 is discharged from the second vent hole 71 before the second vent hole 71 is not closed.
Then, under the pressure of the water flow, the anti-siphon seat 60 blocks the second vent hole 71, the water flows into the water passing cavity 70 and then flows to the drainage pipeline 20, and meanwhile, the water flow discharges the air in the water passing cavity 70 into the drainage pipeline 20; the water flow is divided under the action of the flow guide mechanism 40, and each flow channel 42 guides the water flow; since the bottom end opening of the exhaust duct 30 communicates with the through-flow passage 23, the air in the through-flow passage 23 and the air in the water passing chamber 70 are discharged into the exhaust duct 30 via the bottom end opening of the exhaust duct 30 and then discharged from the first vent hole 32.
Because the check valve 50 is light and has a high water pressure, the air pressure in the exhaust pipe 30 is also high, the first vent hole 32 is blocked by lifting the check valve 50, although most or all of the air in the overflow channel 23 is discharged from the exhaust pipe 30 under the pressure of water flow, some air may not be discharged from the exhaust pipe 30 and remain in the exhaust pipe 30, but has no influence on the drainage pipe 20. Thus, no air or only a small amount of air flows into the main flushing water passage 4 or the washing water passage 5 from the water discharge pipe 20, and the noise of the toilet flushing device during flushing is greatly reduced.
