[0003] Odor-proof drain cores are mainly used with sewer pipes to prevent foul odors from rising up and polluting indoor air. While the odor-proof drain cores in the above-mentioned solution can provide some odor prevention, the pressure in the sewer pipes constantly changes due to the continuous generation of foul odors. Since the opening and closing of the cover in the above-mentioned solution is fixed, it cannot adapt to the changing pressure. Therefore, over time, air leakage will occur, causing the odor-proof drain core to lose its odor-proof function. Utility Model Content

[0004] The purpose of this invention is to provide an odor-proof core with better odor-proof effect.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] An odor-proof core includes a tubular body, an odor-proof cover, and a driving mechanism. The tubular body has an inlet at its upper end and an outlet at its lower end. The odor-proof cover is rotatably mounted on the tubular body, allowing it to be closed or open. The driving mechanism drives the odor-proof cover to rotate to the closed outlet state. The odor-proof cover is characterized by having a sealing ring with a suspended sealing edge that can seal with the outlet.

[0007] Because gas is constantly generated in the sewer pipes, causing the gas pressure inside to change continuously, the above-mentioned technical solution, which involves installing a sealing ring on the odor-proof cover, can effectively prevent odor leakage. The sealing ring has a suspended sealing edge that can seal with the water outlet. When the gas pressure inside the sewer pipe is less than or equal to the external gas pressure, the odor-proof cover can maintain a closed water outlet under the drive of the driving mechanism. When the gas pressure inside the sewer pipe is greater than the external gas pressure, the suspended sealing edge will deform under the greater gas pressure to fit more tightly against the water outlet, preventing odor leakage from the sewer pipe and resulting in a better odor-proof effect.

[0008] When the drive mechanism drives the odor-proof cover to rotate to the state of closing the water outlet, there is a gap between the odor-proof cover and the water outlet.

[0009] By adopting the above technical solution, there is a gap between the odor-proof cover and the water outlet. When the air pressure in the sewer pipe is high, the odor-proof cover can be further tightened against the water outlet to better cope with changes in the air pressure in the sewer pipe and prevent gas leakage in the sewer pipe.

[0010] When the drive mechanism rotates the odor-proof cover to the state of closing the water outlet, the gap between the odor-proof cover and the water outlet is 0.2-0.5mm.

[0011] By adopting the above technical solution, the gap between the odor-proof cover and the water outlet is set to 0.2-0.5mm, which can better adapt to different air pressures in the sewer pipe.

[0012] The outlet has an inclined surface that contacts the suspended sealing edge, and the inclined surface slopes outward from top to bottom.

[0013] By adopting the above technical solution, an inclined surface is formed at the edge of the outlet that contacts the suspended sealing edge. The inclined surface can increase the contact area between the outlet and the suspended sealing edge when the suspended sealing edge deforms, thereby improving its airtightness. The inclined surface slopes outward from top to bottom, which can make the inclined surface form a funnel structure that is smaller at the top and larger at the bottom, thereby further increasing the sealing performance of the suspended sealing edge on the outlet.

[0014] The suspended seal has an inclined section adapted to the inclined surface.

[0015] By adopting the above technical solution, the inclined section can make the fit between the suspended sealing edge and the inclined surface tighter, so as to ensure the sealing performance.

[0016] The sealing ring includes an annular fixing part and a suspended sealing edge extending outward from the outer periphery of the annular fixing part. The top surface of the odor-proof cover is provided with a protruding mounting part, and a pressure cap is provided on the mounting part. The annular fixing part is sleeved on the mounting part and pressed between the pressure cap and the top surface of the odor-proof cover.

[0017] By adopting the above technical solution, during installation, the annular fixing part can be first fitted onto the mounting part, and then the pressure cap can be pressed onto the annular fixing part, so that the sealing ring can be fixed between the pressure cap and the top surface of the odor-proof cover through the annular ring, which facilitates the assembly of the sealing ring.

[0018] The odor-proof cover is rotatably connected to the lower end of the tubular body via a rotating shaft. The driving mechanism includes a first magnet and a second magnet. The first magnet is disposed at the lower end of the tubular body, and the second magnet is disposed on the rotating shaft. The first magnet and the second magnet attract each other, keeping the odor-proof cover in a closed state of the water outlet.

[0019] By adopting the above technical solution, the first magnet and the second magnet attract each other to keep the odor-proof cover in a closed water outlet state. Magnets, as common items in life, can reduce production costs to a certain extent.

[0020] The lower end of the tubular body is provided with a first shaft groove that matches both ends of the rotating shaft. The lower end of the tubular body is provided with a cover. The cover is provided with a second shaft groove that matches both ends of the rotating shaft. The first shaft groove and the second shaft groove form a shaft hole for mounting both ends of the rotating shaft. A sealed cavity is formed between the cover and the tubular body. The first magnet and the second magnet are located in the cavity.

[0021] By adopting the above technical solution, during installation, the two ends of the rotating shaft can be aligned with the first shaft groove, and then the cover can be installed at the lower end of the tubular body, so that the first shaft groove and the second shaft groove correspond to each other to form shaft holes for installing the two ends of the rotating shaft. The sealed chamber can prevent the parts inside the chamber from being disturbed by the outside. Attached Figure Description

[0029] Reference Figures 1 to 7 The odor-proof core shown below will be further described through specific embodiments and in conjunction with the accompanying drawings:

[0030] An odor-proof core includes a tubular body 1, an odor-proof cover 2, and a drive mechanism 3.

[0031] The tubular body 1 has an inlet 11 at the upper end and an outlet 12 at the lower end. A handle 111 is provided in the inlet 11 for easy removal during disassembly and assembly. The odor-proof cover 2 is rotatably mounted on the tubular body 1, which can be closed or open at the outlet 12. The drive mechanism 3 drives the odor-proof cover 2 to rotate to the closed outlet 12 state.

[0032] A sealing ring 4 is provided on the odor-proof cover 2. A protruding mounting part 21 is provided on the top surface of the odor-proof cover 2. A pressure cap 22 is provided on the mounting part 21. The sealing ring 4 includes an annular fixing part 41 and a suspended sealing edge 42 extending outward from the outer periphery of the annular fixing part 41. The annular fixing part 41 is sleeved on the mounting part 21 and pressed between the pressure cap 22 and the top surface of the odor-proof cover 2. The suspended sealing edge 42 can seal with the water outlet 12. The edge of the water outlet 12 forms an inclined surface 121 that contacts the suspended sealing edge 42. 121 slopes outward from top to bottom, and the suspended sealing edge 42 has an inclined section 421 that matches the inclined surface 121. During use, when the air pressure inside the sewer pipe is less than or equal to the outside air pressure, the odor-proof cover 2 can keep the outlet 12 closed under the drive of the drive mechanism 3. When the air pressure inside the sewer pipe is greater than the outside air pressure, the suspended sealing edge 42 is subjected to greater air pressure, and the inclined section 421 will deform to fit more tightly against the outlet, preventing the leakage of odor from the sewer pipe and making the odor-proof effect better.

[0033] The odor-proof cover 2 is rotatably connected to the lower end of the tubular body 1 via a rotating shaft 23. The lower end of the tubular body 1 is provided with a first shaft groove 13 that matches both ends of the rotating shaft 23. The lower end of the tubular body 1 is provided with a cover 14. The cover 14 is provided with a second shaft groove 141 that matches both ends of the rotating shaft 23. The first shaft groove 13 and the second shaft groove 141 form a shaft hole for mounting both ends of the rotating shaft 23. A sealed chamber 15 is formed between the cover 14 and the tubular body 1. After installation, the first magnet 31 and the second magnet 32 ​​are located in the chamber 15.

[0034] The driving mechanism 3 includes a first magnet 31 and a second magnet 32. The first magnet 31 is located at the lower end of the tubular body 1, and the second magnet 32 ​​is located on the rotating shaft 23. The first magnet 31 and the second magnet 32 ​​attract each other, keeping the odor-proof cover 2 in the closed outlet 12 state. When the driving mechanism 3 drives the odor-proof cover 2 to rotate to the closed outlet 12 state, as... Figure 7 As shown, there is a gap d between the odor-proof cover 2 and the water outlet 12. The gap d is 0.2-0.5mm. In actual production, a suitable gap d can be selected according to different actual needs. When the air pressure in the sewer pipe is high, the odor-proof cover 2 can be further pressed against the water outlet 12 to better cope with the changes in the air pressure in the sewer pipe and prevent gas leakage in the sewer pipe.

[0035] When in use, simply align the outlet 12 at the lower end of the tubular body 1 with the drain pipe to be installed and insert it. When you need to remove it, simply pull the handle 111 located in the inlet 12 at the upper end of the tubular body 1.

[0036] The above description is merely a preferred embodiment of the present utility model, and therefore cannot be construed as limiting the scope of the present utility model. All equivalent changes and modifications made in accordance with the scope of the patent application and the contents of the specification of the present utility model shall still fall within the scope of the patent of the present utility model.
