DETAILED DESCRIPTION OF THE EMBODIMENTS

[0014] In order to deepen the understanding and recognition of the present utility model below, the technical solutions in the embodiments of the present utility model will be clearly and completely described and introduced in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments, and no any form of limitation is imposed on this embodiment. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0015] Please refer to Figure 1-2, the present utility model provides a technical solution: an odor removal device for a sewage suction truck, including a sewage suction truck main body 1. A storage tank 2 is fixedly connected to the upper end of the sewage suction truck main body 1. A separation cylinder 3 is rotatably connected inside the storage tank 2. An extrusion block 9 is fixedly connected to the right side end of the separation cylinder 3. A one-way intake valve 4 is fixedly connected to the left side of the storage tank 2. When the air pressure inside the storage tank 2 decreases, the one-way intake valve 4 opens to allow external air to enter the storage tank 2. The one-way intake valve 4 only allows gas to flow in one direction. The one-way intake valve 4 is a mature existing technology, and its specific structure will not be elaborated here as it does not affect the integrity of this solution. A deodorization box 5 is fixedly connected to the right inner wall of the storage tank 2. A sliding plate 6 is provided in the middle of the deodorization box 5. A guide plate 8 is provided at the lower end of the sliding plate 6. An air intake hole 12 is provided on the right side of the deodorization box 5. The sliding plate 6 is located below the air intake hole 12. Two support plates 10 are fixedly connected to the upper end of the sliding plate 6. A rubber block 13 is provided between the two support plates 10. A top plate 14 is fixedly connected to the upper end of the rubber block 13. A sealing piston 11 is fixedly connected to the side end of the sliding plate 6. An exhaust pipe 21 is provided in the middle of the upper end of the deodorization box 5. The upper end of the exhaust pipe 21 penetrates through the storage tank 2. A medicine adding box 16 is fixedly connected to the left side of the deodorization box 5. A blocking plate 15 is fixedly connected to the left support plate 10. A sealing block 18 is slidably connected to the upper inner wall of the deodorization box 5. The gas inside the storage tank 2 enters the deodorization box 5 through the air intake hole 12, is compressed and discharged inside the deodorization box 5, and the gas inside the storage tank 2 continues to enter the deodorization box 5. When the air pressure inside the storage tank 2 decreases, the one-way intake valve 4 will be opened to allow fresh gas to enter the storage tank 2 to ensure the air pressure balance inside the storage tank 2.

[0016] The sliding plate 6 is of a T-shaped structure. An adjusting plate 7 is slidably connected to the lower end of the sliding plate 6. A bolt is threadedly connected to the side end of the sliding plate 6. The lower end of the adjusting plate 7 is fixedly connected to the guide plate 8. The guide plate 8 is of an arc-shaped structure. The upper end of the extrusion block 9 is of an arc-shaped structure. When the extrusion block 9 is located below the guide plate 8, the sealing piston 11 blocks the air intake hole 12. The separation cylinder 3 drives the extrusion block 9 to rotate together. When the extrusion block 9 moves to below the guide plate 8, the extrusion block 9 squeezes the guide plate 8, thereby jacking up the guide plate 8 and the sliding plate 6. When the sliding plate 6 and the sealing piston 11 slide, the gas above the sliding plate 6 is compressed. When the sliding plate 6 moves, the sealing piston 11 blocks the air intake hole 12.

[0017] The blocking plate 15 is of an L-shaped structure. A connection port 17 is provided in the middle of the blocking plate 15. A connection channel is provided in the middle of the deodorization box 5. The medicine adding box 16 is communicated with the connection channel. When the sliding plate 6 is located at the lowest position, the connection port 17 is communicated with the connection channel, so that the medicine enters the deodorization box 5 from the medicine adding box 16. When the sliding plate 6 moves upward to compress the gas, the high pressure makes the medicine and the gas fully mixed. At the same time, the blocking plate 15 blocks the connection channel to prevent the medicine from flowing in continuously.

[0018] The side end of the sealing block 18 is an arc structure. An extrusion screw 19 is inserted into the right side of the sealing block 18. The extrusion screw 19 is threadedly connected to the deodorization box 5. A connecting spring 20 is provided between the extrusion screw 19 and the sealing block 18. The lower end of the rubber block 13 is fixedly connected to the sliding plate 6. The top plate 14 faces the exhaust pipe 21. The two sides of the upper end of the top plate 14 are inclined structures. By rotating the extrusion screw 19, the deformation degree of the connecting spring 20 is changed, so that the sealing block 18 will move only when it is subjected to different degrees of extrusion force.

[0019] The gas in the storage tank 2 enters the deodorization box 5 through the air inlet hole 12. The connection port 17 is communicated with the communication channel, so that the medicine enters the deodorization box 5 from the medicine adding box 16. The separation cylinder 3 drives the extrusion block 9 to rotate together. When the extrusion block 9 moves below the guide plate 8, the extrusion block 9 extrudes the guide plate 8. The sealing piston 11 compresses the gas at the upper end of the sliding plate 6. At the same time, the sealing piston 11 blocks the air inlet hole 12 to prevent the gas from continuing to enter the deodorization box 5. When the top plate moves to the sealing block 18, the top plate 14 extrudes the sealing block 18. After pushing the sealing block 18 open, the compressed gas can be discharged through the exhaust pipe 21. When the extrusion screw 19 is rotated to change the deformation degree of the connecting spring 20 and then change the distance between the guide plate 8 and the sliding plate 6, when the extrusion block extrudes, the sliding plate moves different distances. When the top plate 14 extrudes the sealing block 18 again, the rubber block 13 will deform, so as to control the degree of gas compression, so that the medicine and the gas are fully mixed.

For those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
