Description

Technical Field

[0001] This application relates to the field of sanitary ware, and in particular to a one-way self-closing mechanism. Background Technology

[0002] Sanitary ware is a common sanitary appliance in daily life. When in use, excrement can be flushed into the sewage pipe by water, but the odor emitted can pollute the indoor air and cause varying degrees of harm to the human body.

[0003] In traditional sanitary ware, to prevent odors from sewage pipes from overflowing into the room, a one-way self-closing structure is usually installed in the sewage pipe. Traditional one-way self-closing structures are typically one-way valves. The internal structure of one-way valves is complex, resulting in higher operating costs. Furthermore, the connection between the one-way valve and the sewage pipe is also relatively complex. Utility Model Content

[0004] In order to reduce the cost and installation difficulty of unidirectional self-closing structures, this application provides a unidirectional self-closing mechanism.

[0005] The unidirectional self-closing mechanism provided in this application adopts the following technical solution:

[0006] A one-way self-closing mechanism includes a connecting ring and a pipe body. The drain pipe of a sanitary ware is inserted into the inner side of the connecting ring, and a sewage pipe is sleeved on the outer side of the connecting ring. A sealing part is formed by an inward indentation on one side of the pipe body in the diameter direction. The sealing part is arc-shaped and abuts against the inner wall of the pipe body. The sealing part is an elastic sealing part. When the weight of the water flow in the pipe body is greater than the elastic force of the sealing part, the sealing part springs outward and opens the pipe body. When the weight of the water flow in the pipe body is less than the elastic force of the sealing part, the sealing part resets and seals the pipe body.

[0007] By adopting the above technical solution, the connecting ring is first fitted onto the drain pipe of the sanitary ware, and then the sewage pipe is fitted onto the connecting ring, thus completing the installation of the one-way self-closing mechanism. During daily use, when the weight of the water flow inside the pipe is greater than the elastic force of the elastic seal, the seal springs outward, allowing wastewater from the sanitary ware to flow into the sewage pipe through the pipe. When the weight of the water flow inside the pipe is less than the elastic force of the elastic seal, the seal resets and seals the pipe, preventing odors from overflowing from the sewage pipe. This design, consisting of a connecting ring, pipe, and seal, is simple in structure, reducing both the cost and installation difficulty of the one-way self-closing mechanism.

[0008] Preferably, the connecting ring has an inner shrinking ring connected to the pipe body at one end near the pipe body. The diameter of the inner shrinking ring gradually decreases from the connecting ring toward the pipe body, and the end of the sanitary ware drain pipe abuts against the inner shrinking ring.

[0009] By adopting the above technical solution, the connecting ring is sleeved on the drain pipe. When the end of the drain pipe abuts against the inner ring, the installation position of the connecting ring can be positioned, thereby quickly completing the installation of the connecting ring.

[0010] Preferably, a retaining ring is provided on the outer wall of the connecting ring, and the end of the sewage pipe abuts against the retaining ring.

[0011] By adopting the above technical solution, the sewage pipe is sleeved on the connecting ring. When the end of the sewage pipe abuts against the retaining ring, the installation position of the sewage pipe can be located, thereby quickly completing the installation of the sewage pipe.

[0012] Preferably, the connecting ring, inner shrink ring, retaining ring, tube body, and sealing part are rubber connecting ring, rubber inner shrink ring, rubber retaining ring, rubber tube body, and rubber sealing part integrally formed.

[0013] By adopting the above technical solution, the connecting ring, inner shrink ring, retaining ring, tube body and sealing part are formed by rubber integral casting, which reduces the production cost of the one-way self-closing mechanism and improves the production efficiency of the one-way self-closing mechanism.

[0014] Preferably, an inner sealing ring is provided on the inner sidewall of the connecting ring.

[0015] By adopting the above technical solution, when the connecting ring is fitted onto the drain pipe of the sanitary ware, the inner sealing ring seals the connecting ring and the drain pipe. On the one hand, this improves the installation stability of the connecting ring, and on the other hand, it improves the sealing performance between the connecting ring and the drain pipe.

[0016] Preferably, an outer sealing ring is provided on the outer side wall of the connecting ring.

[0017] By adopting the above technical solution, when the sewage pipe is sleeved on the connecting ring, the outer sealing ring seals the connecting ring and the sewage pipe. On the one hand, this improves the installation stability of the connecting ring, and on the other hand, it improves the sealing performance between the connecting ring and the sewage pipe.

[0018] Preferably, both the inner and outer sealing rings are provided in multiples along the diameter direction of the connecting ring.

[0019] By adopting the above technical solution, multiple inner sealing rings and outer sealing rings seal the connection between the drain pipe, connecting ring, and sewage pipe, thereby further improving the sealing effect of the connecting ring.

[0020] Preferably, all of the inner and outer sealing rings are integrally formed with the rubber connecting ring.

[0021] By adopting the above technical solution, both the inner and outer sealing rings are made of rubber and are integrally cast with the connecting rod, thereby reducing the production difficulty of the one-way self-closing mechanism and improving its production efficiency.

[0022] In summary, this application includes at least one of the following beneficial technical effects:

[0023] 1. By using a connecting ring, pipe body and sealing part to form a one-way self-closing mechanism, the cost of using the one-way self-closing mechanism is reduced. The one-way self-closing mechanism can be quickly installed by connecting the connecting ring to the drain pipe and sewage pipe. The external spring and reset of the sealing part can realize the opening and closing of the pipe body, thereby achieving the effect of one-way sealing to prevent odor from overflowing.

[0024] 2. By using an inner shrink ring and a retaining ring to position the drainage pipe and sewage pipe, the installation location is easily determined, thus facilitating the rapid installation of the one-way self-closing mechanism;

[0025] 3. By using inner and outer sealing rings to seal the connection between the drain pipe, connecting ring, and sewage pipe, the sealing effect of the connecting ring is improved. Attached Figure Description

[0029] The following is in conjunction with the appendix Figure 1-2 This application will be described in further detail.

[0030] This application discloses a one-way self-closing mechanism.

[0031] Reference Figure 1 and 2 A one-way self-closing mechanism includes a connecting ring 1, an inner shrinking ring 4, and a tube body 2, all integrally cast from rubber. The connecting ring 1 is connected to one end of the inner shrinking ring 4 along its axial direction, and the tube body 2 is connected to the other end of the inner shrinking ring 4 along its axial direction. The diameter of the inner shrinking ring 4 gradually decreases from the connecting ring 1 toward the tube body 2.

[0032] Two inner sealing rings 6 are coaxially and integrally cast on the inner wall of the connecting ring 1, and the two inner sealing rings 6 are spaced apart along the axial direction of the connecting ring 1. When installing the one-way self-closing mechanism, the connecting ring 1 is fitted onto the drain pipe of the sanitary ware. When the end of the drain pipe abuts against the inner wall of the inner retraction ring 4, the connecting ring 1 is in place. At this time, the two inner sealing rings 6 are pressed tightly against the outer wall of the drain pipe, thereby sealing the connection between the drain pipe and the connecting ring 1.

[0033] Two outer sealing rings 7 are integrally cast coaxially on the outer wall of the connecting ring 1, and the two outer sealing rings 7 are arranged at intervals along the axial direction of the connecting ring 1. A retaining ring 5 is integrally cast coaxially on the end of the outer wall of the connecting ring 1 away from the pipe body 2, and the outer diameter of the retaining ring 5 is larger than the outer diameter of the outer sealing rings 7.

[0034] When the connecting ring 1 is installed on the drain pipe, the sewage pipe is fitted onto the connecting ring 1. When the end of the sewage pipe abuts against the retaining ring 5, the connecting ring 1 is installed in place, thus completing the installation of the one-way self-closing mechanism. At this time, the two outer sealing rings 7 are pressed against the inner wall of the sewage pipe, thereby sealing the connection between the sewage pipe and the connecting ring 1.

[0035] First, place the connecting ring 1 onto the drain pipe of the sanitary ware, and then place the sewage pipe onto the connecting ring 1. This completes the installation of the one-way self-closing mechanism, thus greatly reducing the installation difficulty of the one-way self-closing mechanism.

[0036] A sealing part 3 is integrally cast on one side of the pipe body 2 along the diameter direction. The sealing part 3 is arc-shaped and inclined along the diameter direction of the pipe body 2. From the connecting ring 1 towards the pipe body 2, the sealing part 3 gradually approaches the pipe body 2, and the end of the sealing part 3 away from the connecting ring 1 seals against the inner wall of the pipe body 2.

[0037] The rubber sealing part 3 has a certain elasticity. When the weight of the water flow inside the pipe body 2 is less than the elastic force of the sealing part 3 to deform, the water flow is insufficient to cause the sealing part 3 to deform. At this time, the sealing part 3 presses against the inner wall of the pipe body 2, thereby sealing the pipe body 2 and preventing the odor in the sewage pipe from overflowing into the room through the one-way self-closing mechanism.

[0038] When the weight of the water flow inside the pipe body 2 is greater than the elastic force of the sealing part 3 when it deforms, the water flow pushes open the sealing part 3 and causes it to bounce outward. At this time, the sealing part 3 is separated from the inner wall of the pipe body 2, the pipe body 2 is in the open state, and the wastewater in the sanitary ware is discharged into the sewage pipe through the pipe body 2.

[0039] After the wastewater is discharged, the water flow in the pipe body 2 decreases or disappears. When the weight of the water flow in the pipe body 2 is less than the elastic force of the sealing part 3 when it deforms, the sealing part 3 elastically resets and adheres tightly to the inner wall of the pipe body 2, thereby sealing the pipe body 2 again.

[0040] Molten rubber is poured into a production mold. After the rubber cools, the mold is opened and the finished product is removed. At this point, the end of the sealing part 3 furthest from the connecting ring 1 is integrally connected to the tube body 2. The end of the sealing part 3 furthest from the connecting ring 1 is then cut and separated from the tube body 2, thus completing the production of the one-way self-closing mechanism. All components of the one-way self-closing mechanism are integrally cast from rubber, resulting in a simple structure and low production and usage costs.

[0041] The implementation principle of this application embodiment is as follows: Wastewater in the sanitary ware is discharged into the pipe body 2 through the drain pipe. When the weight of the water flow in the pipe body 2 is greater than the elastic force of the sealing part 3, the water flow opens the sealing part 3 and causes it to spring outward. At this time, the sealing part 3 is separated from the inner wall of the pipe body 2, the pipe body 2 is in the open state, and the wastewater is discharged into the sewage pipe through the pipe body 2. After the wastewater is discharged, the water flow in the pipe body 2 decreases or there is no water. When the weight of the water flow in the pipe body 2 is less than the elastic force of the sealing part 3 again, the sealing part 3 elastically resets and sticks tightly to the inner wall of the pipe body 2, thereby sealing the pipe body 2 and preventing the odor in the sewage pipe from overflowing.

[0042] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
