Description

Technical Field

[0001] This utility model relates to the field of drainage pipe fittings technology, and in particular to a dry and wet dual-use odor-proof S-bend pipe fitting. Background Technology

[0002] The comfort of living environment has always been a long-term goal for people to improve and pursue. Among them, bathroom odor has become a long-standing problem that plagues people's living comfort. In the building drainage system, the water trap of the S-bend fitting is used to prevent odors from the drainage pipes from entering the house. Currently, there are two floor drains in residential bathrooms: dry and wet. The water seal of the dry floor drain cannot be automatically replenished and needs to be manually replenished regularly. The water traps in the dry and wet areas will also dry out after a period of time.

[0003] Therefore, a float is installed inside the S-bend fitting. When the water trap inside the S-bend dries out, the float seals the passage, preventing odors from entering the residence. However, the existing float installation in the S-bend fitting, by sealing the passage, hinders drainage within the pipes and needs improvement. Utility Model Content

[0004] The purpose of this utility model is to propose an S-bend pipe fitting that does not affect the drainage of the pipe inside the S-bend fitting, and still has a good sealing effect on odors after the water dries up.

[0005] This utility model proposes a dual-purpose (dry and wet) odor-proof S-bend pipe fitting, comprising a first vertical section, a second vertical section, a third vertical section, a bottom bend, and a top bend. The two ends of the bottom bend are respectively connected to the bottom ends of the first and second vertical sections. The two ends of the top bend are respectively connected to the top ends of the second and third vertical sections. A float chamber is provided above the bottom bend, and the float chamber is connected to the interior of the S-bend pipe fitting. A float is provided inside the float chamber, and the height of the float is greater than the diameter of the S-bend pipe fitting. Limiting strips are vertically provided on both side walls of the float chamber, and limiting grooves are formed on both sides of the float, with the limiting strips embedded in the limiting grooves.

[0006] Preferably, the float is made of rubber material.

[0007] Preferably, the vertical cross-section of the float is shaped like an olive.

[0008] Preferably, the height of the float is set to "H" and H=70mm; the diameter of the S-bend is set to "L" and L=50mm.

[0009] Preferably, the height difference between the top bend and the bottom bend of the S-bend pipe fitting is set to "N", and N=150mm.

[0010] Preferably, an inspection port is formed at the bottom bend of the S-bend fitting, the inspection port faces the float chamber, and an installation pipe extends outward from the inspection port, with a sealing cap threaded onto the installation pipe.

[0011] Preferably, the inspection port is circular, the diameter of the inspection port is set to "D", the thickness of the float is set to "C", and D>C.

[0012] Preferably, the S-bend fitting is made of UPVC plastic.

[0013] As can be seen from the above description of this utility model, this utility model has the following beneficial effects:

[0014] 1. When water is inside the S-bend fitting, the float will rise into the float chamber under the action of buoyancy; when the water inside the S-bend fitting dries up, the float can block the channel, thus having a good blocking effect on odors, and does not affect the drainage of the pipe inside the S-bend fitting.

[0015] 2. Limiting strips are vertically installed on both sides of the float chamber and the bottom bend. Correspondingly, limiting grooves are formed on both sides of the float. The limiting strips are embedded in the limiting grooves to limit the rise and fall of the float and prevent the float from shifting position during the rise and fall process.

[0016] 3. An inspection port is formed at the bottom bend of the S-bend pipe fitting. An installation pipe extends outward from the inspection port, and a sealing cap is threadedly connected to the installation pipe. The inspection port facilitates the internal maintenance of the S-bend pipe fitting. The sealing cap is fixed to the installation pipe by a threaded connection, which not only provides a firm fixation but also facilitates easy disassembly. Attached Figure Description

[0023] To make the technical problem to be solved, the technical solution and the beneficial effects of this utility model clearer and more understandable, the following description is provided in conjunction with the appendix. Figure 1-5 The present invention will be further described in detail below with reference to the embodiments. It should be understood that the specific embodiments described herein are only for explaining the present invention and are not intended to limit the present invention.

[0024] Reference Figure 1 and Figure 2 A dual-purpose (wet and dry) odor-proof S-bend pipe fitting is disclosed. The S-bend pipe fitting comprises a first vertical section 1, a second vertical section 2, a third vertical section 3, a bottom elbow 4, and a top elbow 5. The second vertical section 2 is located between the first vertical section 1 and the third vertical section 3, ensuring that the first vertical section 1, the second vertical section 2, and the third vertical section 3 are parallel to each other. The bottom elbow 4 connects the bottom ends of the first vertical section 1 and the second vertical section 2, and the top elbow 5 connects the top ends of the second vertical section 2 and the third vertical section 3.

[0025] Reference Figure 3 , Figure 4 and Figure 5 A float chamber 6 is provided above the bottom bend 4 of the S-bend pipe fitting. The float chamber 6 is located between the first vertical section 1 and the second vertical section 2 of the S-bend pipe fitting, with one side of the float chamber 6 connected to the first vertical section 1 and the bottom end of the float chamber 6 connected to the bottom bend 4 of the S-bend pipe fitting. The height difference between the top bend 5 and the bottom bend 4 of the S-bend pipe fitting is set to "N", and the height difference between the top bend 5 and the bottom bend 4 of the S-bend pipe fitting satisfies N=150mm. A float 7 is provided in the float chamber 6. Limiting strips 61 are formed inside the float chamber 6 and on both sides of the bottom bend 4. Correspondingly, limiting grooves 71 are vertically formed on both sides of the float 7, so that the limiting strips 61 on both sides of the float chamber 6 are engaged in the limiting grooves 71 on both sides of the float 7.

[0026] This ensures that the float 7, under the action of the two limiting strips 61, can only move up and down within the float chamber 6 and the bottom bend 4. When there is water in the S-bend fitting, the float 7 will rise into the float chamber 6 under the buoyancy of the water. The height of the float 7 is set to "H", and the height of the float 7 is H=70mm; the diameter of the S-bend fitting is set to "L", and the diameter of the S-bend fitting is L=50mm. When the water in the S-bend fitting dries up, the float 7 in the float chamber 6 loses buoyancy. Since the height of the float 7 is greater than the diameter of the S-bend fitting, the float 7 sinks and blocks the pipe opening, preventing odors and insects from entering the indoor drain.

[0027] The float 7 is made of rubber and has a hollow interior, making its density lower than that of water. Its vertical cross-section is olive-shaped, which facilitates greater buoyancy and helps maintain verticality in the water within the S-bend fitting, reducing friction between the float 7 and the limiting strip 61 during buoyancy-induced rise and fall. The S-bend fitting is made of UPVC plastic, which offers excellent corrosion resistance, unaffected by moisture, soil acidity, alkali, or salt, resulting in a longer service life. UPVC S-bend fittings also have lower maintenance costs. Furthermore, the smooth inner wall and low flow resistance of the UPVC S-bend fitting enhance its water delivery capacity.

[0028] Reference Figure 2 and Figure 3 When a fault occurs inside the S-bend fitting, an inspection port 41 is formed at the bottom bend 4 of the S-bend fitting to facilitate internal maintenance. The inspection port 41 is located at the corner of the bottom bend 4 and faces the float chamber 6. The inspection port 41 is circular, with a diameter of "D" and a thickness of "C", such that the relationship between the diameter of the inspection port 41 and the thickness of the float 7 satisfies D>C. Therefore, when the float 7 needs to be replaced, it can be removed from the inspection port 41. An installation pipe 8 extends outward from the inspection port 41 of the S-bend pipe fitting, and a sealing cap 9 is threadedly connected to the installation pipe 8 to seal the inspection port 41 of the S-bend pipe fitting. The threaded connection between the sealing cap 9 and the installation pipe 8 not only makes the sealing cap 9 and the installation pipe 8 firmly fixed, but also makes the sealing cap 9 and the installation pipe 8 easy to disassemble.

[0029] The specific implementation principle of this application embodiment is as follows: When water is stored in the S-bend fitting, the float 7 inside the S-bend fitting gradually rises under the action of buoyancy, causing the float 7 to be hidden in the float chamber 6. The water stored in the S-bend fitting prevents odors from the drainage pipe from entering the residence. When the S-bend fitting dries out, the float 7 descends into the bottom bend 4 under the action of gravity, thereby sealing the passage of the S-bend fitting and preventing odors from the drainage pipe from entering the residence. During the rising and falling of the float 7, the limiting strips 61 on both sides of the float chamber 6 and the bottom bend 4 move within the limiting grooves 71 on both sides of the float 7. The limiting strips 61 on both sides of the float chamber 6 and the bottom bend 4 limit the float 7 to prevent the float 7 from shifting position during the rising and falling process. In addition, when it is necessary to inspect the inside of the S-bend fitting, the sealing cover 9 is removed from the installation pipe 8, and then the float 7 can be taken out from the S-bend fitting through the inspection port 41. The opening of the inspection port 41 facilitates the inspection of the inside of the S-bend pipe fitting, and the sealing cap 9 is fixed to the installation pipe 8 by a threaded connection, which not only provides a firm fixation but also has the advantage of easy disassembly.

[0030] The present invention has been described above by way of example with reference to the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any non-substantial improvements made using the inventive concept and technical solution of the present invention, or the direct application of the inventive concept and technical solution to other situations without modification, shall be protected by the present invention.
