Detailed Description

Referring to fig. 1, a toilet drainage mechanism comprises a ceramic body 1, wherein a urinal 2 and a sewage pipe 3 are arranged in the ceramic body 1, wherein the sewage pipe 3 comprises a sewage pipe inlet 31 connected to the bottom of the urinal, a sewage pipe outlet 32 communicated with a corridor sewer and an S-bend 33 positioned between the sewage pipe inlet 31 and the sewage pipe outlet 32. The structure is the prior art, and the reason that the closestool stopped up is mainly that S bends the section and stops up, because it relies on siphon principle blowdown mainly. The water seal line of the urinal is L.

The bottom of the urinal and the opposite side of the sewage outlet 31 are provided with an overflow pipe connector 34, one end of the overflow connecting pipe 6 is connected with the overflow pipe connector 34, and the other end is connected with a three-way body 7. The three-way body 7 is arranged at the front end of the ceramic body (and the rear end is arranged at the side where the S-bend of the sewage discharge pipe 3 is positioned), and the position of the three-way body is higher than the water seal line L.

This tee bend body 7 has three cavity, and first cavity passes through overflow connecting pipe 6 and overflow pipe interface 34 to be connected, and the second cavity is connected with overflow blow off pipe 5, and the third cavity is connected with inlet tube 4, and overflow blow off pipe 5's the other end is connected in blow off pipe export 32 department.

Referring to fig. 2 and 3, a special-shaped sealing gasket 8 is arranged inside the three-way body 7, and is located in the third cavity and close to the intersection of the first cavity and the second cavity. The shaped gasket 8 comprises a body 81, a through hole 82 is formed in the body 81, and an elastic membrane capable of sealing and opening the through hole is arranged on one side of the through hole, and in the embodiment, the elastic membrane comprises an elastic membrane upper part 83 and an elastic membrane lower part 84.

The utility model discloses an use as follows:

referring to fig. 1 to 3, in a normal state, the through hole 82 is sealed by the elastic membrane, a distance is reserved between the right side of the lower part 84 of the elastic membrane and the inner wall of the body, the first cavity and the second cavity are communicated, and if blockage occurs at the moment, sewage can enter the first cavity from the overflow connecting pipe 6, then enter the overflow sewage discharge pipe 5 from the second cavity, and then enter the sewage discharge pipe outlet 32. Since the elastic membrane closes the through hole 82, the sewage cannot enter the third cavity to pollute the water inlet pipe 4.

When inlet tube 4 intake, because hydraulic effect, the elastic membrane is opened to the right, and through-hole 82 is opened, and elastic membrane lower part 84 and the contact of body inner wall seal the second cavity simultaneously, and the water of inlet tube gets into first cavity to get into the urinal bottom, because its play water direction is to blow off pipe import 31, consequently, can strengthen the blowdown effect.

The above description is only a preferred embodiment of the present invention, and therefore the scope of the present invention should not be limited by this description, and all equivalent changes and modifications made within the scope and the specification of the present invention should be covered by the present invention.
