[0022] The following is a further description of the present invention in conjunction with the attached Figures 1-5 drawings.

[0023] To solve the technical problems in the background art, the present application provides: an exhaust gas testing and sampling device after garbage incineration, including an exhaust pipe 1 and a collection pipe 9. An outlet pipe 2 is fixedly connected to the outside of the exhaust pipe 1. One end of the outlet pipe 2 is fixedly connected to a solenoid valve 3. One end of the solenoid valve 3 is fixedly connected to a delivery pipe 4. A fan 5 is provided outside the delivery pipe 4. The input end of the fan 5 is fixedly connected to a first pipe 6. The first pipe 6 is fixedly connected to the delivery pipe 4. The output end of the fan 5 is fixedly connected to a second pipe 7. The second pipe 7 is fixedly connected to the outlet pipe 2. Valves 8 are fixedly connected in both the first pipe 6 and the second pipe 7. After the collection is completed, the fan 5 can be started to pump the exhaust gas in the delivery pipe 4 into the outlet pipe 2, thus avoiding the leakage of the exhaust gas through the delivery pipe 4.

[0024] In a further design, the collection pipe 9 is detachably connected to the delivery pipe 4. The collection pipe 9 and the delivery pipe 4 are threadedly connected. Additionally, a sleeve 10 is fixedly connected inside the collection pipe 9. A slide bar 12 is slidably connected in the sleeve 10. A fixing ring 13 is fixedly connected to the outer portion of the slide bar 12. A first spring 11 is sleeved on the outer portion of the slide bar 12. Two ends of the first spring 11 are respectively fixedly connected to the fixing ring 13 and the inner wall of the collection pipe 9. One end of the slide bar 12 is fixedly connected to a sealing plate 14. A convex ring 15 is fixedly connected inside the port of the collection pipe 9. Under the elastic force of the first spring 11, the sealing plate 14 abuts against the convex ring 15, thereby realizing the closing of the port of the collection pipe 9. In order to increase the sealing performance, a sealing ring or other sealing structures can also be sleeved on the outer portion of the sealing plate 14.

[0025] In this embodiment, a connecting rod 21 is also fixedly connected inside the delivery pipe 4. A push column 22 is fixedly connected to the outer portion of the connecting rod 21. Additionally, a sliding sleeve 23 is slidably connected to the outer portion of the push column 22. A diversion hole 24 is provided on the inner wall of the sliding sleeve 23. The diversion hole 24 is of an L-shaped structure. A sliding ring 18 is fixedly connected to the outer portion of the sliding sleeve 23. A second spring 20 is connected between the sliding ring 18 and the delivery pipe 4. A second magnet 19 is fixedly connected to the outer portion of the sliding ring 18. A first magnet 17 is slidably connected to the outer portion of the delivery pipe 4. The first magnet 17 and the second magnet 19 are arranged with the same poles repelling each other. A threaded ring 16 is rotatably connected to the outer portion of the first magnet 17. The threaded ring 16 is threadedly connected to the outer portion of the delivery pipe 4. The following is an explanation of the above technical solution: Rotate the threaded ring 16 to make the first magnet 17 approach the second magnet 19. Thus, the second magnet 19 will drive the sliding sleeve 23 to slide outwards, so that one end of the diversion hole 24 is located inside the collection pipe 9, facilitating the inflow of waste gas into the collection pipe 9.

[0026] For those skilled in the art to fully understand the technical solution, the usage method of this embodiment is as follows:

[0027] Thread the collection pipe 9 onto the outer portion of the delivery pipe 4. Thus, the push column 22 will abut against the sealing plate 14, and the sealing plate 14 will compress the first spring 11, thereby disengaging from the convex ring 15 and opening the port of the collection pipe 9.

[0028] Then rotate the threaded ring 16 to make the first magnet 17 approach the second magnet 19. Thus, the second magnet 19 will drive the sliding sleeve 23 to slide outwards, so that one end of the diversion hole 24 is located inside the collection pipe 9, as shown in the attached Figure 3 figure;

[0029] Then, open the solenoid valve 3, and the waste gas in the exhaust pipe 1 will flow into the collection pipe 9 through the diversion hole 24 for collection. After the collection is completed, rotate the threaded ring 16 to move the first magnet 17 away from the second magnet 19. Thus, under the elastic force of the second spring 20, the sliding sleeve 23 will slide into the delivery pipe 4, and the output end of the diversion hole 24 will be in contact with the inner wall of the delivery pipe 4, so that the waste gas will not be discharged. Then, rotate and remove the collection pipe 9;

[0030] Subsequently, open the valve 8, close the solenoid valve 3, and start the fan 5 to pump the waste gas in the delivery pipe 4 into the outlet pipe 2, which can avoid the leakage of waste gas through the delivery pipe 4.

[0031] The above specific implementation manners further elaborate on the purpose, technical solution, and beneficial effects of the present utility model. It should be understood that the above description is only the specific implementation manners of the present utility model and is not used to limit the protection scope of the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included in the protection scope of the present utility model.
