[0029] In some examples, the mounting assembly 9 includes a connecting groove 91, a fixing groove 92, a cavity 93, a through groove 94 and a fixing block 95. The connecting groove 91 runs through the middle of the mounting seat 7 and is adapted to the size of the connector 8. The fixing groove 92 is opened on the outer surface of the connector 8. The cavity 93 is opened inside the mounting seat 7 and is located on the periphery of the connecting groove 91. The through groove 94 runs through the inner wall of one side of the cavity 93 and is connected to the connecting groove 91. The fixing block 95 is slidably connected to the through groove 94 and is adapted to the size of the fixing groove 92. The connector 8 is placed in the connecting groove 91, and then the fixing block 95 is inserted into the fixing groove 92. At this time, the connector 8 can be fixed in the connecting groove 91, thereby completing the connection between the intake pipe 4 or the exhaust pipe 6 and the processing box 1.

[0030] In some examples, the mounting assembly 9 also includes a swivel 96, an arc block 97, a first slide groove 98, a first slider 99 and a first spring 910. The swivel 96 is rotatably connected to the cavity 93, the arc block 97 is fixedly connected to one side of the swivel 96 close to the connecting groove 91, the first slide groove 98 is opened at the top of the mounting seat 7 and is connected to the cavity 93, the first slider 99 is fixedly connected to the top of the swivel 96 and slidably connected to the first slide groove 98, the first spring 910 is installed inside the first slide groove 98 and its two ends are respectively fixedly connected to one side of the first slider 99 and the inner wall of one side of the first slide groove 98. The first slider 99 is slid along the first slide groove 98 to squeeze the first spring 910. During this process, the swivel 96 will drive the arc block 97 to rotate synchronously with the first slider 99 in the cavity 93. When the first slider 99 is released, the first spring 910 rebounds and can drive the swivel 96 and the arc block 97 to rotate in the opposite direction through the first slider 99 to reset.

[0031] In some examples, the mounting assembly 9 further includes a second slide groove 911, a second slider 912, and a second spring 913. The second slide groove 911 is opened at the bottom of the cavity 93 and is below the fixed block 95. The second slider 912 is fixedly connected to the bottom of the fixed block 95 and is slidably connected to the second slide groove 911. The second spring 913 is installed inside the second slide groove 911 and its two ends are respectively fixedly connected to one side of the second slider 912 close to the connecting groove 91 and the inner wall of the second slide groove 911 close to the connecting groove 91. The first spring 913 is fixedly connected to the second slide groove 911 and the inner wall of the second slide groove 911 close to the connecting groove 91. The elastic force of the first spring 910 is greater than the sum of the elastic forces of the multiple groups of second springs 913. When the arc block 97 moves away from the rear of the fixed block 95, the second spring 913 rebounds and drives the fixed block 95 to move toward the inside of the cavity 93 through the second slider 912. When the arc block 97 moves to the rear of the fixed block 95, since the elastic force of the first spring 910 is greater than the sum of the elastic forces of the multiple groups of second springs 913, the arc block 97 will push the fixed block 95 out toward the connecting groove 91 and squeeze the second spring 913 through the second slider 912.

[0032] In some examples, the sealing assembly 10 includes a sealing groove 101, an installation groove 102 and a sealing ring 103. The sealing groove 101 is opened on the outer surface of the connector 8 and is above the fixing groove 92. The installation groove 102 is opened on the inner wall of the connecting groove 91 and is above the fixing block 95. The sealing ring 103 is installed inside the installation groove 102 and is adapted to the size of the sealing groove 101 after expansion. The sealing ring 103 is made of rubber and is hollow inside. After the connector 8 is fixed in the connecting groove 91, air is inflated into the sealing ring 103 to make it expand. When the sealing ring 103 fits tightly with the sealing groove 101, the connection between the connector 8 and the connecting groove 91 can be sealed.

[0033] In some examples, the sealing assembly 10 also includes an air cavity 104, a piston 105, a connecting hole 106 and a connecting rod 107. The air cavity 104 is opened inside the mounting seat 7 and one end is connected to the first slide groove 98. The piston 105 is slidably connected to the air cavity 104 and is of a matching size. The connecting hole 106 is opened on the side wall of the air cavity 104 away from the first slide groove 98 and is connected to the sealing ring 103. The two ends of the connecting rod 107 are respectively fixedly connected to the first slider 99 and the piston 105. By sliding the first slider 99 along the first slide groove 98, the piston 105 can be driven to slide synchronously in the air cavity 104 through the connecting rod 107, thereby sending the air in the air cavity 104 to the sealing ring 103 through the connecting hole 106 or drawing the air in the sealing ring 103 to the air cavity 104 through the connecting hole 106.

[0034] In a specific application scenario, first slide the first slider 99 along the first slide groove 98 to squeeze the first spring 910. During this process, the swivel 96 drives the arc block 97 to rotate in the cavity 93 along with the first slider 99. When the arc block 97 moves away from the rear of the fixed block 95, the second spring 913 rebounds and drives the fixed block 95 to move toward the inside of the cavity 93 through the second slider 912. At the same time, the connecting rod 107 drives the piston 105 to slide synchronously with the first slider 99 along the air cavity 104 and pass through the connecting hole 106 to The air in the sealing ring 103 is pumped into the air cavity 104. When the fixing block 95 is immersed in the cavity 93 and the sealing ring 103 is reduced to the minimum, the connector 8 is placed in the connecting groove 91 and the fixing groove 92 is aligned with the position of the fixing block 95. Then the first slider 99 is released, the first spring 910 rebounds and drives the swivel 96 and the arc block 97 to move in the opposite direction through the first slider 99. When the arc block 97 contacts the fixing block 95, the elastic force of the first spring 910 is greater than the sum of the elastic forces of the multiple sets of second springs 913. Therefore, the arc block 97 will fix The block 95 is pushed out in the direction of the connecting groove 91 and squeezes the second spring 913 through the second slider 912. When the fixing block 95 is inserted into the fixing groove 92, the connector 8 can be fixed in the connecting groove 91, thereby completing the installation of the intake pipe 4 and the exhaust pipe 6 and the processing box 1. At the same time, the connecting rod 107 drives the piston 105 to slide synchronously along the air cavity 104 with the first slider 99 and sends the air in the air cavity 104 to the sealing ring 103 through the connecting hole 106 to make it expand. When the sealing ring 103 expands to be tightly connected with the sealing groove 101, the sealing ring 103 is pressed against the sealing groove 101. When they fit tightly together, the connection between the connector 8 and the connection groove 91 can be sealed, and then the odor treatment work can be started. The gas collecting hood 5 will send the odorous gas generated in the sewage treatment process to the treatment box 1 through the air inlet pipe 4. When the gas contacts the baffle 12, the baffle 12 will break up the gas and make it rise only through the through holes on its surface, so that it can evenly contact with the activated carbon adsorption layer 11. When the gas contacts the activated carbon adsorption layer 11, the odor can be adsorbed. After the adsorption is completed, the gas can be discharged through the exhaust pipe 6.

[0035] By adopting the above technical solution, not only can the installation and disassembly of the intake and exhaust pipes and the treatment box be simpler and faster, effectively improving work efficiency, but the connection between the intake and exhaust pipes and the treatment box can also be sealed, effectively preventing gas leakage.

[0036] Finally, it should be noted that the above embodiments are merely examples for the purpose of illustrating the present invention and are not intended to limit its implementation. Those skilled in the art will readily appreciate that other variations or modifications based on the above description are possible. It is not necessary and impossible to enumerate all implementation methods here. Obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
