[0002] With the widespread application of fume pollution in industrial production, welding processing, and laboratory operations, the problem of fume pollution has received increasing attention. Fume often contains harmful gases and dust particles, which not only pollute the environment but also seriously threaten the health of operators. As an important device for purifying air, fume absorption devices play a key role in these fields.

[0003] However, the filter element, the core component of a smoke absorption device, is responsible for filtering harmful substances in smoke. The filter element is usually installed on the smoke absorption device by screws. When the filter element needs to be replaced, tools such as screwdrivers are required to unscrew the screws, which is time-consuming and laborious, affecting the efficiency of filter element replacement. Therefore, we need to consider how to solve this problem. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology and propose a smoke absorption device that facilitates filter replacement. It is equipped with a fixed plate, a rotating shaft and a first clamping plate, etc. With the cooperation of a bidirectional threaded rod, a sliding plate and a second clamping plate, the filter is fixed from different positions, which greatly enhances the reliability of the fixation. Moreover, the filter is easy to remove and install, and easy to replace.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] Reference Figures 1-8 A smoke absorption device with easy filter replacement includes a base plate 1. Multiple casters 2 are installed at the lower end of the base plate 1, and a push rod 3 is fixedly connected to the upper end of the base plate 1. Through the cooperation of the casters 2 and the push rod 3, the smoke absorption device can move flexibly in different working scenarios, greatly improving work efficiency. A housing 4 is fixedly connected to the upper end of the base plate 1. A sealing door 5 is hinged to one side of the outer wall of the housing 4. An air outlet is opened on the outer side wall of the housing 4. A filter 6 is installed inside the housing 4. A fixed plate 7 is fixedly connected to the inner wall of the housing 4. A rotating shaft 8 is rotatably connected to the side wall of the fixed plate 7. A rotating disk 9 is fixedly connected to one end of the rotating shaft 8. The other end of the rotating shaft 8 passes through the fixed plate 7 and the housing 4 in sequence and extends to the outside. A first knob 10 is fixedly connected to the outer end of the rotating shaft 8. A rubber layer is provided on the first knob 10. An arc groove 11 is opened on the rotating disk 9. Multiple U-shaped plates 12 are fixedly connected to the side wall of the fixed plate 7. A moving plate 13 is slidably connected to the inner wall of each U-shaped plate 12.

[0026] Each movable plate 13 has a movable rod 14 fixedly connected to its other side wall. Each movable rod 14 is engaged with a corresponding arc groove 11. Each movable plate 13 has a first clamping plate 15 fixedly connected to its other side wall. Each first clamping plate 15 is engaged with the filter element 6. By rotating the first knob 10, the rotating shaft 8 and the rotating disk 9 are rotated. The arc groove 11 on the rotating disk 9 is engaged with the movable rod 14, so that the movable plate 13 drives the first clamping plate 15 to move, thereby loosening or clamping the filter element 6. A bidirectional threaded rod 16 is rotatably connected between the inner walls of the two sides of the housing 4. Each of the two threaded ends of the bidirectional threaded rod 16 is threadedly connected with a sliding plate 17. Each of the two sliding plates 17 is fixedly connected to the opposite side of the two sliding plates 17. The two second clamping plates 18 are engaged with the filter element 6. One end of the bidirectional threaded rod 16 extends to the outside and is fixedly connected with a second knob 19. A rubber layer is provided on the second knob 19.

[0027] Rotating the second knob 19 causes the bidirectional threaded rod 16 to rotate, which in turn moves the sliding plate 17 and the second clamping plate 18, further fixing or loosening the filter element 6. The entire replacement process is simple to operate and does not require complicated tools, allowing for the disassembly and installation of the filter element 6. This greatly saves time and labor costs associated with replacing the filter element 6. Furthermore, the fixing structure composed of multiple U-shaped plates 12, moving plates 13, moving rods 14, and the first clamping plate 15, combined with the bidirectional threaded rod 16, sliding plate 17, and second clamping plate 18, securely clamps the filter element 6, ensuring its stability during device operation. There will be no shaking or displacement, ensuring the stability and effectiveness of smoke filtration and extending the service life of filter element 6. A fan 20 is installed at the upper end of the housing 4. The air inlet end of the fan 20 is fixedly connected to the air inlet pipe 21, and the other end of the air inlet pipe 21 is fixedly connected to the suction hood 22. The air outlet end of the fan 20 is connected to the inside of the filter element 6 through the air outlet pipe 23. The fan 20 can effectively draw smoke into the housing 4 through the air inlet pipe 21 and the suction hood 22, and discharge it after being filtered by the filter element 6. This achieves efficient absorption and filtration of smoke, which helps to improve the air quality of the working environment.

[0028] In this invention, during use, the push rod 3 is pushed to make the caster 2 roll, thereby enabling the entire smoke absorption device to move flexibly in different working scenarios. Then, the fan 20 is started. The air inlet of the fan 20 generates suction through the air inlet pipe 21 and the suction hood 22 to draw in the surrounding smoke. The smoke enters the fan 20 through the suction hood 22 and the air inlet pipe 21, and then enters the filter element 6 through the air outlet pipe 23. Under the action of the filter element 6, impurities in the smoke are filtered out, and the filtered air is discharged from the air outlet on the outer side wall of the housing 4, thereby achieving efficient absorption and filtration of smoke and improving the air quality of the working environment.

[0029] When filter element 6 needs to be replaced, turn the first knob 10 to rotate the shaft 8, which in turn rotates the rotating disk 9. Through the cooperation of the arc groove 11 and the moving rod 14, the moving rod 14 moves with the rotation of the arc groove 11. The moving rod 14 will drive the moving plate 13 to slide within the U-shaped plate 12, thereby causing the first clamping plate 15 to move away from the filter element 6 and release its clamping on the filter element 6. At the same time, turn the second knob 19 to rotate the bidirectional threaded rod 16, which in turn causes the two sliding plates 17 to move in opposite directions, thereby causing the second clamping plate to move away from the filter element 6. 18 also moves away from the filter element 6, further loosening the fixation on the filter element 6. After the first clamping plate 15 and the second clamping plate 18 have both loosened the filter element 6, open the sealing door 5 to remove the old filter element 6 from the housing 4. Place the new filter element 6 into the housing 4, positioning it between the first clamping plate 15 and the second clamping plate 18. Then, rotate the first knob 10 and the second knob 19 in the opposite direction, causing the first clamping plate 15 and the second clamping plate 18 to move towards the filter element 6 respectively, clamping and fixing the new filter element 6. Finally, close the sealing door 5 to complete the replacement of the filter element 6.

[0030] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
