Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] Example: See Figure 1-5 The utility model provides a technical solution: an underground sewage odor treatment device, comprising an odor purifier 1, a gas collecting pipe 2 is connected to the bottom of the odor purifier 1, and an exhaust pipe 3 is arranged on the top of the odor purifier 1; a retaining ring 10 is installed on the inner wall of the odor purifier 1, an activated carbon stuffing box 7 is arranged on the retaining ring 10, an adsorption stuffing box 8 is arranged on the activated carbon stuffing box 7, and protrusions 9 are installed on the activated carbon stuffing box 7 and the adsorption stuffing box 8, and a plurality of sieve holes are opened at the bottom of the activated carbon stuffing box 7 and the adsorption stuffing box 8, a sealing cover 4 is installed at the bottom of the exhaust pipe 3, a sealing ring 5 is installed at the bottom of the sealing cover 4, the sealing ring 5 is in contact with the top opening of the odor purifier 1, a plurality of telescopic columns 11 are installed at the bottom of the sealing ring 5, and a sieve plate is installed at the bottom of the telescopic column 11 13, the sieve plate 13 is in contact with the top of the adsorption stuffing box 8, two positioning structures are provided on the odor purifier 1 and the cover 4, the telescopic column 11 is sleeved with a positioning spring 12, one end of the positioning spring 12 is installed on the sieve plate 13, and the other end of the positioning spring 12 is installed on the sealing ring 5, and the activated carbon filler and the adsorption filler are filled into the activated carbon stuffing box 7 and the adsorption stuffing box 8 respectively, and then the activated carbon stuffing box 7 is placed on the retaining ring 10, and the adsorption stuffing box 8 is placed on the activated carbon stuffing box 7, and the sealing ring 5 on the cover 4 is aligned with the opening of the odor purifier 1 and pressed tightly. At this time, the sieve plate 13 is pressed on the adsorption stuffing box 8 under the elastic force of the positioning spring 12, so that when purifying the odor, its stability when placed in the odor purifier 1 is improved.

[0023] Furthermore, the positioning structure includes an L-shaped rod 6, which is mounted on the cover 4, a fixed block 61 is mounted on the odor purifier 1, the L-shaped rod 6 is plugged into the fixed block 61, a plug-in block 62 is slidably mounted on the fixed block 61, a shifting block 64 is mounted on the plug-in block 62, a plug-in slot 63 is provided on the L-shaped rod 6, the plug-in block 62 is plugged into the plug-in slot 63, a movable slot 65 is provided on the fixed block 61, the plug-in block 62 is slidably mounted in the movable slot 65, a retaining spring 66 is provided in the movable slot 65, one end of the retaining spring 66 is mounted on the plug-in block 62, and the other end of the retaining spring 66 is mounted on the inner wall of the movable slot 65. When the cover 4 and the sealing ring 5 are tightly closed on the top of the odor purifier 1, the plug-in block 62 is shifted to both sides by the shifting block 64 and compressed to the retaining spring 66, and then the L-shaped rod 6 is plugged into the fixed block 61, and the plug-in block 65 is released. 2. The plug-in block 62 will slide into the plug-in groove 63 under the rebound action of the retaining spring 66 to fix the L-shaped rod 6, thereby stably connecting the odor purifier 1 with the cover 4 and the exhaust pipe 3, improving the airtightness during odor purification. After long-term use, when the activated carbon filler and the adsorption filler need to be replaced, the plug-in block 62 is slid to both sides through the pull block 64 to make the plug-in block 62 slide out of the plug-in groove 63, and the L-shaped rod 6 is pulled out from the fixing block 61, thereby the exhaust pipe 3 and the cover 4 can be removed and opened from the top of the odor purifier 1, and the activated carbon filler box 7 and the adsorption filler box 8 can be taken out from the inside of the odor purifier 1 through the protrusion 9, and the activated carbon filler and the adsorption filler can be replaced, which is convenient and quick, and prevents the performance of the activated carbon filler and the adsorption filler from being reduced after long-term use, resulting in a poor purification effect.

[0024] Furthermore, a limit rod 67 is slidably installed on the plug-in block 62, and a retaining spring 66 is sleeved on the limit rod 67. The limit rod 67 is installed on the inner wall of the movable groove 65. The limit rod 67 can limit the sliding of the plug-in block 62 in the movable groove 65, and can subsequently be accurately inserted into the plug-in groove 63 to fix the L-shaped rod 6.

[0025] The working principle is as follows: first, fill the activated carbon filler and the adsorption filler into the activated carbon filler box 7 and the adsorption filler box 8, then put the activated carbon filler box 7 on the retaining ring 10, put the adsorption filler box 8 on the activated carbon filler box 7, align the sealing ring 5 on the cover 4 with the opening of the odor purifier 1 and press it tightly. At this time, the sieve plate 13 is pressed tightly on the adsorption filler box 8 under the elastic force of the positioning spring 12. When the cover 4 and the sealing ring 5 are closed on the top of the odor purifier 1, the plug-in block 62 is pushed to both sides by the shifting block 64 and compressed to the retaining spring 66, and then the L-shaped rod 6 is inserted into the fixing block 61, and the plug-in block 62 is released. The plug-in block 62 will be in the retaining spring 66. Under the rebound effect, it slides into the plug-in groove 63 to fix the L-shaped rod 6, thereby stably connecting the odor purifier 1 with the cover 4 and the exhaust pipe 3, improving the airtightness during odor purification. After long-term use, when the activated carbon filler and the adsorption filler need to be replaced, the plug-in block 62 is slid to both sides through the dial block 64, so that the plug-in block 62 slides out of the plug-in groove 63, and the L-shaped rod 6 is pulled out from the fixing block 61, thereby the exhaust pipe 3 and the cover 4 can be removed and opened from the top of the odor purifier 1, and the activated carbon filler box 7 and the adsorption filler box 8 are taken out from the inside of the odor purifier 1 through the protrusion 9, and the activated carbon filler and the adsorption filler can be replaced.
