[0034] Reference Figure 1 , Figure 2 as well as Figure 3 A horizontal frame 2 is fixedly connected to the inner wall of the filter box 1, and a horizontal filter screen 22 is connected inside the frame 2. The filter screen 22 is located between the air inlet pipe 11 and the air outlet pipe 12 in the vertical direction. The dust carried in the air entering the filter box 1 through the air inlet pipe 11 will be trapped by the filter screen 22. A driving mechanism 3 is installed on the filter box 1. The driving mechanism 3 includes a knob 31, a transmission rod 32, a first gear 33 and a second gear 34. The knob 31 is rotatably connected to the outer wall of the filter box 1. The end of the knob 31 away from the filter box 1 is coaxially connected to a connecting rod 35, and the end of the connecting rod 35 away from the knob 31 is connected to a handle Rod 36, the length of the handle rod 36 is greater than the diameter of the knob 31, which plays a role in saving effort. The transmission rod 32 is coaxially connected with the knob 31 and extends into the filter box 1 in the horizontal direction. The transmission rod 32 is located below the filter screen 22. The first gear 33 is coaxially connected to the end of the transmission rod 32 away from the knob 31. A horizontal fixing rod 4 is fixedly connected to the inner side wall of the filter box 1. The end of the fixing rod 4 away from the filter box 1 is rotatably connected to a vertical rotating shaft 41. The second gear 34 is sleeved on the rotating shaft 41. The first gear 33 and the second gear 34 are meshed so that the rotating shaft 41 can be driven to rotate when the knob 31 is rotated.

[0035] Reference Figure 1 , Figure 2 as well as Figure 3 The upper end of the rotating shaft 41 is coaxially connected with a threaded column 42, and a fixing bolt 43 and a first scraper 5 are threadedly connected to the threaded column 42. The fixing bolt 43 is located at the lower end of the first scraper 5 and is set tightly against the first scraper 5. The first scraper 5 is slidably connected with a second scraper 6 along the length direction of the first scraper 5.

[0036] Reference Figure 1 , Figure 3 as well as Figure 4The first scraper 5 is provided with a reset mechanism 7 for restoring the position of the second scraper 6. The reset mechanism 7 includes a limit groove 72 and a spring 71. The limit groove 72 is opened at the upper end of the first scraper 5 and is arranged along the length direction of the first scraper 5. The second scraper 6 is slidably connected in the limit groove 72. The spring 71 is horizontally arranged in the limit groove 72. The two ends of the spring 71 are respectively connected to the first scraper 5 and the second scraper 6. When the edge of the filter screen 22 is far away from the first scraper 5, the spring 71 pushes the second scraper 6 so that the second scraper 6 can scrape the filter screen. The edge of the net 22, when the first scraper 5 is close to the edge of the filter screen 22, the side wall of the filter box 1 pushes the second scraper 6 into the limiting groove 72, so that the first scraper 5 can rotate smoothly, and the second scraper 6 is rotatably connected to the roller 8 at one end away from the first scraper 5, and the lower end of the frame 2 is provided with a guide groove 21, and the guide groove 21 is arranged along the circumference of the frame 2. The roller 8 rotates and cooperates with the guide groove 21. The guide groove 21 plays a role in limiting the roller 8, which facilitates the circumferential rotation of the roller 8 along the filter screen 22, making the extension and retraction of the second scraper 6 more convenient.

[0037] Reference Figure 4 Two limiting rods 51 are fixedly connected to the inner side walls at both ends of the limiting groove 72, and two slots 61 for engaging with the limiting rods 51 are provided on the second scraper 6. The engaging of the limiting rods 51 and the slots 61 reduces the occurrence of the second scraper 6 slipping out of the limiting groove 72.

[0038] The implementation principle of a heat storage exhaust gas treatment device that is easy to clean in an embodiment of the present application is as follows: dust in the exhaust gas is intercepted by the filter 22 and accumulated on the filter 22. The operator rotates the handle bar 36, and the handle bar 36 drives the knob 31 to rotate. When the knob 31 rotates, the transmission rod 32, the first gear 33 and the second gear 34 drive the rotating shaft 41 to rotate. The rotating shaft 41 drives the first scraper 5 and the second scraper 6 to rotate and scrape the surface of the filter 22. The scraped dust is collected by the collection box 15.

[0039] When the first scraper 5 rotates, the distance from the edge of the filter screen 22 will change. When the edge of the filter screen 22 is far away from the first scraper 5, the spring 71 pushes the second scraper 6 so that the second scraper 6 can scrape the edge of the filter screen 22. When the first scraper 5 is close to the edge of the filter screen 22, the side wall of the filter box 1 pushes the second scraper 6 into the limiting groove 72. The second scraper 6 contacts the inner wall of the filter box 1 through the roller 8. The roller 8 reduces the friction between the second scraper 6 and the filter box 1, making it easier for the second scraper 6 to be pushed into the limiting groove 72, reducing the rotation force of the operator, and making it more convenient for the operator to clean the filter screen 22.

[0040] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
