Detailed Description
In order to more clearly illustrate the technical solutions of the embodiments of the present invention, the following description of the present invention is provided with reference to the accompanying drawings, which are only some embodiments of the present invention, and it is obvious for a person skilled in the art to obtain other drawings without creative efforts.
As shown in fig. 1 to 4, a drainage structure of a toilet according to an embodiment of the present invention includes a drainage pipe 10, a drainage pipe 20, and a check valve 30. Wherein the drain pipe 10 is used for discharging the filth in the toilet bowl (not shown), and the drain pipe 10 is provided with a drainage port 11 penetrating through the inside and the outside of the drain pipe 10. One end of the drainage tube 20 is communicated with the drainage port 11 to drain water to the drainage port 11 to form a drainage channel, i.e., the drainage channel drains water into the sewage pipe 10 and then the water is discharged from the sewage pipe 10. The check valve 30 is provided on the soil pipe 10 and is capable of opening the drainage port 11 in one direction (by opening and closing the drainage port 11 to open and close the aforementioned drainage passage) under the hydraulic pressure of the drainage tube 20 so that the water of the drainage tube 20 flows into the soil pipe 10, and when there is no water or insufficient hydraulic pressure in the drainage tube 20, the check valve 30 closes the drainage port 11 to prevent the water or gas in the soil pipe 10 from flowing out through the drainage port 11. That is, the check valve 30 is in a closed state in a normal state, so that when the sewage pipe 10 is prevented from being blocked, sewage in the sewage pipe 10 flows out from the drainage port 11, and simultaneously, odor in the sewage pipe 10 is prevented from leaking to the outside from the drainage port 11, when water flows in the drainage pipe 20 and the water pressure is enough to open the check valve 30, the check valve 30 opens the drainage port 11 under the effect of the water pressure so that the water flows into the sewage pipe 10 through the drainage port 11.
Alternatively, the mounting position of the check valve 30 can be selectively set on the drainage tube 20 as long as it can be used for opening and closing the drainage channel, and the check valve 30 is selectively set on the top of the sewage pipe 10 for the sake of simpler structure and more convenient installation.
Specifically, in this embodiment, the top of the sewage pipe 10 is provided with a holding cavity 12 protruding the surface of the sewage pipe 10, the holding cavity is communicated with the inner cavity of the sewage pipe 10, and the check valve 30 is disposed in the holding cavity 12. Specifically, one side of the accommodating cavity 12 is formed with an opening 121, the detachable sealing cover at the opening 121 is connected with a cover body 13, the cover body 13 is detachably clamped and fixed with the sewage discharge pipe 10, the drainage port 11 is arranged on the cover body 13, and the cover body 13 is hermetically connected with the sewage discharge pipe 10 through a sealing ring 14. When the one-way valve 30 is installed, the cover body 13 is detached from the sewage draining pipe 10, the one-way valve 30 is arranged in the accommodating cavity 12 through the opening 121, and after the one-way valve 30 is arranged in the accommodating cavity 12, the cover body 13 is covered at the opening 121, so that the one-way valve 30 is convenient to install.
In this embodiment, the check valve 30 is disposed below the drainage port 11, the check valve 30 is in open-close fit with the drainage port 11 to control the opening and closing of the drainage channel, and the check valve 30 opens the drainage port 11 downward in one direction under the action of water pressure.
Specifically, the check valve 30 includes a valve plate 31, an elastic member 32, and a sealing member 33, where the valve plate 31 can close the drainage opening 11 under the elastic force of the elastic member 32, and the valve plate 31 seals and closes the drainage opening 11 through the sealing member 33. The valve plate 31 is installed in the accommodating cavity 12 in a swinging manner, a rotating shaft rotatably installed in the accommodating cavity 12 is arranged on the valve plate 31, and the sealing element 33 is a sealing sheet fixed on the valve plate 31. The elastic element 32 is a compression spring, the compression spring is elastically propped between one end of the valve plate 31 and the inner wall of the accommodating cavity 12, and the other end of the valve plate 31 is matched with the drainage port 11 in an opening and closing manner. When the drainage tube 20 is filled with water, one end of the valve plate 31 swings open under the action of water flow pressure to open the drainage port 11, and meanwhile, the pressure spring is compressed by the other end of the valve plate 31; when the drainage tube 20 has no water or the water pressure is insufficient, the pressure spring is reset to drive the valve plate 31 to swing to the initial position, and further the drainage port 11 is closed. It should be understood that the resilient member 32 may take other forms, such as a spring or a resilient arm.
Alternatively, as shown in fig. 5 and 6, in another embodiment, the valve plate 31 can be slidably mounted in the accommodating cavity 12, and the effect is the same as that of the valve plate 31 being pivotally mounted.
Alternatively, as shown in fig. 7 and 8, in another embodiment, the check valve 30 may also include a valve plate 31, a weight block 34 and a sealing member 33, the valve plate 31 can close the drainage port 11 under the gravity of the weight block 34, the weight block 34 and the valve plate 31 are separately formed and then connected or integrally formed, and the valve plate 31 seals and closes the drainage port 11 through the sealing member 33.
