The drain valve 140 is hinged with the housing 110 to perform opening and closing actions of the drain valve 140. At least a portion of the trapway cover 130 sinks into the trapway 120 and is proximate the hinge point of the trapway valve 140 and the housing 110. When the drain valve 140 is in a closed state (as shown in fig. 1), the sewage or waste liquid is stopped at the side of the drain valve 140 near the water inlet pipe 150, and at this time, the drainage is stopped; when the drain valve 140 is opened (as shown in fig. 2), the drain valve 140 is laminated with the drain chamber cover 130, and sewage or waste liquid is smoothly discharged from the water inlet pipe 150 through the drain passage 160. The water inlet pipe 150 and the sewage draining cavity 120 are arranged on the same side of the sewage draining channel 160 and are communicated with the sewage draining channel 160, so that water inlet and water draining can smoothly flow through the sewage draining channel 160. Referring to fig. 3, a transmission portion 170 is disposed on an outer sidewall of the trapway 160, and the transmission portion 170 is in transmission connection with the trapway 140, so as to implement opening and closing actions of the trapway 140 through the transmission portion 170.

The flanges are attached to the end periphery of the interface 200 to ensure a sealing effect and to the inner liner and the outer liner, respectively. The sealing lip 191 may be a multi-layer specially designed for forming a sealing structure added according to the shape of the liner, i.e., the sealing member 190 may include a plurality of sealing lips 191, the plurality of sealing lips 191 being disposed at intervals in the axial direction of the interface 200. The sealing lip 191 is part of the liner and may provide additional sealing properties. The multiple sealing lip 191 design may provide more contact area to better prevent leakage or infiltration of sewage from the interface. When sewage is topped up, they form a layer-by-layer barrier between the interface 200 and the liner, more effectively improving the sealing performance. In addition, the spacing helps to ensure even distribution between the sealing lips 191 and to support each other, to increase the stability of the overall seal, to cope with different stress and pressure conditions, and to provide a durable sealing effect. The fixing portion 192 is connected to the outside of the sealing portion and is connected to the housing 110. The casing 110 is provided with an insert 193, the insert 193 is arranged on the outer side of the butt joint 200, the fixing part 192 is provided with a matching groove corresponding to the insert 193, the insert 193 is arranged in the matching groove of the fixing part 192 in an inserting or assembling mode, the insert 193 can play a role in supporting and fixing, and the fixing part 192 of the sealing element 190 is firmly connected to the casing 110 through the insert 193.

The housing 110 may also have a water passing port, which is an opening or hole in the housing 110 that communicates with the trapway 160, allowing liquid to pass through, the water passing port being adapted to direct the flow of water in the trapway 160 and form a directing channel that is at least partially higher than the trapway 160 through which, when the trapway 160 is blocked, the waste water or waste liquid in the trapway 160 may be directed to a higher position to facilitate monitoring of the flow of water in the trapway 160. The sensor 210 is disposed on the path of the guide channel and above the sewage channel 160, and the sensor 210 is used for detecting liquid and outputting a signal to the sewage system. By positioning the sensor 210 in the path of the pilot channel, a blockage in the trapway 160 can be more easily detected; by arranging the sensor 210 above the sewage drain 160, when the sewage drain 160 is blocked, sewage or waste liquid flows to a guide pipeline communicated with the sensor 210 through a water outlet, and when the sewage or waste liquid is blocked to a certain extent, the position of the sensor 210 is reached in the guide pipeline, the sensor 210 triggers blocking protection after detecting the liquid, and the sewage drain system is controlled to stop draining. The sensor 210 may be a contact sensor 210, such as a water level flowmeter, which is used for identifying water full through water flow meter, or a probe, which is used for identifying water full through conduction when meeting water; the sensor 210 may also be a non-contact sensor, such as an infrared sensor, which recognizes that water is full when light emission and reception signals fluctuate when dirt passes.

In combination with the foregoing embodiments, when the trapway 140 is closed, the water outlet is located downstream of the trapway 140, and the liquid is blocked upstream of the trapway 140, cannot pass through the water outlet, and cannot enter the guide channel to trigger the blocking protection of the sensor 210, thereby affecting drainage of the trapway. When the drain valve 140 is opened, the water outlet is lower than the drain valve 140, and the liquid can naturally flow underground through the water outlet and flow into the detection channel in a proper direction. The height of the water passing opening is lower than that of the drain valve 140 when it is opened, so that it is ensured that the occurrence of the reverse flow or blocking condition during the drain process is avoided. The water outlet is provided on the sidewall of the trapway 120. When the sewer is blocked or blocked and sewage or waste liquid is accumulated in the sewer cavity 120 and the water level reaches the water outlet height on the side wall, the sewage or waste liquid flows into the water outlet. The water passing port comprises a first water passing port and a second water passing port, wherein the first water passing port is arranged at the downstream of the second water passing port. The first water passing port and the second water passing port are both arranged on the same side wall of the blowdown cavity 120, and the first water passing port is closer to the outlet of the blowdown channel 160. When the drain valve 140 is opened, the sewage or waste liquid flows to the first water passing port through the second water passing port, and if the sewer is blocked, the sewage or waste liquid can accumulate in the drain pipe and the drain cavity 120 and enter the guide channel from the first water passing port and the second water passing port respectively. Two water passing ports are arranged, so that a liquid flowing passage can be formed, the fluidity of the liquid is increased, and the liquid can enter the sensor 210 more easily; on the other hand, the chance of liquid entering the sensor 210 can be increased, and even if one water passing port is blocked, the other water passing port can still work normally, so that the liquid can enter the sensor 210, and the water level detection and corresponding protection mechanism are triggered normally.
