[0003] In order to control waste gas and avoid air pollution, exhaust equipment is usually used to filter and purify the gas directly when the waste gas is discharged to remove harmful substances in the waste gas. In traditional exhaust equipment, a filter structure is installed at the air inlet port of the exhaust pipe, and the filter is used to intercept large particles of solid impurities, so that the waste gas can be preliminarily treated. However, since the filter structure itself is relatively simple, although it can filter large particles of solid impurities, it is easy to cause the filter to be blocked over a long period of time, and manual cleaning is more troublesome.

[0004] Therefore, it is necessary to provide a new exhaust device to solve the above-mentioned technical problems. Utility Model Content

[0029] The specific implementation of the present utility model is described in detail below in conjunction with specific embodiments.

[0030] See also Figures 1 to 4 The embodiment of the utility model provides an exhaust device, which includes an end cover 1, a guide pipe 2 is fixed to one side of the end cover 1, and also includes:

[0031] The first filter screen 3 is hemispherical and fixed to the inside of the end cover 1 and close to the opening through the mounting frame 4, and a gap is formed between the end cover 1 and the inner wall, and a net box 6 is fixed inside the gap by magnetic attraction, and the box opening of the net box 6 is facing the air inlet port of the end cover 1;

[0032] The cleaning component 5 penetrates through the first filter screen 3 and is rotatably connected thereto. The cleaning component 5 is also attached to the outer convex surface of the first filter screen 3 and scrapes off impurities attached to the surface of the first filter screen 3 by rotating.

[0033] The second filter screen 7 is installed inside the end cover 1 in an inclined shape;

[0034] The shock assembly 8 is rotatably mounted inside the end cover 1 , and the shock assembly 8 can impact on the second filter screen 7 .

[0035] It should be noted that: in the device, a spherical first filter 3 is arranged at the air inlet position of the end cover 1, and a mesh box 6 is filled in the gap between the first filter 3 and the end cover 1, so that during the working process, large particles of impurities can be intercepted by the first filter 3, and at the same time, the airflow drives the cleaning component 5 to rotate, so the cleaning component 5 can also be used to clean the first filter 3, and the cleaned impurities will enter the mesh box 6, which can effectively avoid the first filter 3 from being blocked;

[0036] It should also be noted that the second filter screen 7 is arranged at an angle to intercept impurities with smaller particles. At the same time, the second filter screen 7 can be knocked by the shock component 8, so that the impurities attached thereto can be removed by shock, thereby preventing the second filter screen 7 from being blocked.

[0037] Therefore, this setting can improve the filtering effect, avoid clogging of the filter, and make it easier to clean the filter, which is more practical.

[0038] It should also be noted that the net box 6 is fixed inside the end cover 1 by magnetic attraction, so it is easy to disassemble to facilitate cleaning of impurities accumulated inside.

[0039] In the embodiments of the present invention, please refer to Figures 1 to 3 The cleaning assembly 5 includes a first rotating shaft 51, one end of which is fixed with a coaxial impeller 52, and the other end of which is fixed with a plurality of annularly distributed scrapers 53;

[0040] The first rotating shaft 51 passes through the first filter screen 3 and is rotatably connected thereto via a bearing.

[0041] It should be noted that: in the cleaning component 5, when the airflow acts on the impeller 52, it can drive it to rotate, thereby driving the scraper 53 to rotate through the first rotating shaft 51. The scraper 53 is attached to the outer wall of the first filter screen 3. Therefore, during the rotation process, it can scrape off impurities attached to the first filter screen 3, thereby cleaning the first filter screen 3.

[0042] In the embodiments of the present invention, please refer to Figure 1 , Figure 2 and Figure 4The shock assembly 8 includes a second rotating shaft 81, a handle 82 is fixed at one end of the second rotating shaft 81, and a mounting seat 83 is fixed at the other end. A sliding rod 84 is slidably connected to the mounting seat 83, and a spring 85 is fixed to the sliding rod 84 to press against the mounting seat 83. The other end of the sliding rod 84 is rotatably connected to a roller 86;

[0043] The second rotating shaft 81 passes through the end cover 1 and is rotatably connected thereto;

[0044] And it is also in direct contact with the second filter screen 7 through the roller 86.

[0045] It should be noted that the shock assembly 8 is manual, and the second rotating shaft 81 can be driven to rotate by turning the handle 82, thereby driving the mounting base 83 and the slide bar 84 to rotate. When the roller 86 collides with the second filter screen 7 and continues to rotate, the spring 85 contracts and the slide bar 84 also moves together, and the cycle is repeated to clean the second filter screen 7.

[0046] In the embodiments of the present invention, please refer to Figures 1 to 3 A waste storage box 9 is also clamped at the lower end of the end cover 1.
