[0036] The deodorizing cover 2 includes a cover body 21, a rotating shaft 22, a sealing gasket 23 and a pressing plate 24. The rotating shaft 22 is fixedly arranged on one side of the cover body 21. The cover body 21 can be rotatably arranged at the lower end of the main body 1 through the rotating shaft 22. The rotating shaft 22 is also provided with a first mounting groove 221. The top surface of the cover body 21 is formed with a protruding positioning portion 211 that matches the shape of the sealing gasket 23. A pressing plate 24 is arranged on the top of the positioning portion 211. The sealing gasket 23 is located outside the positioning portion 211 and is pressed by the pressing plate 24 on the inner edge. The sealing gasket 23 is fixed to the cover by glue. The top surface of the main body 21 is located on the outside of the positioning portion 211, and a slot 212 is formed on the top of the positioning portion 211. A protrusion 241 is formed on the bottom of the pressure plate 24 to match the slot 212. The protrusion 241 of the pressure plate 24 can fix the pressure plate 24 in the slot 212 by glue or other fixing methods. The outer edge of the pressure plate 24 is larger than the outer edge of the slot 212, so that the inner edge of the sealing gasket 23 can be pressed under the outer edge of the pressure plate 24. The rotating shaft 22 can also cooperate with the reset mechanism 3 to make the odor-proof cover 2 horizontally cover the drain outlet 14 of the main body 1.

[0037] The reset mechanism 3 includes a first magnet 31 and a second magnet 32. The first magnet 31 is installed in the first installation groove 221.

The first sealing sleeve 6 can be fixed in the annular inner side wall 51 and the main body 1 by the first annular sealing edges 65 having an interference fit with the annular inner side wall 51 and the main body 1.

[0041] The second sealing sleeve 7 is also a tubular structure, including a second upper section 71, a second lower section 74, a second connecting section 73 and a fourth annular portion 72 extending outward from the second upper section 71. The diameter of the second upper section 71 is greater than the diameter of the second lower section 74. The second connecting section 73 is connected between the second upper section 71 and the second lower section 74. The second lower section 74 is sleeved outside the main body 1, and the second upper section 71 is sleeved between the annular outer side wall 53 and the annular limiting portion 54. The outer peripheral surface of the second sealing sleeve 7 is protruding to form a plurality of second annular sealing edges 75 arranged at intervals along its length direction.

[0042] Three guide sections 16 are also provided on the side surface of the lower end of the main body 1. The guide sections 16 can make it easier for the main body 1 to be inserted into the pipe to be installed during installation.

When encountering a large-diameter sewer pipe 9, the second upper section 71 of the second sealing sleeve 7 can be inserted into the large-diameter sewer pipe 9 and can be interference-set in the large-diameter sewer pipe 9 through the second annular sealing edge 75. When encountering a small-diameter sewer pipe When encountering a small diameter drain pipe 8, the small diameter drain pipe 8 can be inserted into the first lower section 64 of the first sealing sleeve 6. When encountering a large diameter drain pipe, the installation method of the large diameter drain pipe is similar to that of the small diameter drain pipe 8, so the large diameter drain pipe is not drawn in the figure. Specifically, the large diameter drain pipe can be inserted into the first upper section 61 of the first sealing sleeve 6.

[0044] In daily use, the odor-proof cover 2 can switch between closing and opening the drain outlet 14 of the main body 1 by cooperating with the reset mechanism 3. The drain outlet 14 of the main body 1 is closed when the odor-proof cover 2 is in a horizontal state. The odor-proof cover 2 in a horizontal state can be subjected to a more uniform force when the air pressure inside the sewer pipe or the reverse overflow of liquid impacts the odor-proof cover 2, making it difficult to open, thereby avoiding odor seepage or liquid overflow.
