[0018] The box body 1 includes a fixed box 11. A ventilation groove 12 is formed in the wall of the fixed box 11. An air outlet groove 16 is formed on one side of the fixed box 11 away from the ventilation groove 12. The side walls inside the fixed box 11 are symmetrically and fixedly connected with limiting blocks 13. The outer walls of the limiting blocks 13 are fixedly connected with the outer walls of elastic extrusion blocks 14. A pin hole 15 is formed in the outer wall of the top of the fixed box 11.

The outer wall of the support plate 21 is slidably connected with the outer wall of the limiting block 13. The limiting blocks 13 inside the fixed box 11 in the box body 1 limit the movement of the support plate 21, ensuring that it is difficult to sway left and right inside the fixed box 11. The elastic extrusion block 14 contacts the support plate 21. On the one hand, it provides a certain buffer and support for the support plate 21.

When the cover 3 is installed, the insertion strip 33 and the limiting plate 32 at the bottom of the connecting plate 31 are quickly inserted into the inside of the fixed box 11 by means of four-corner positioning to achieve the accurate installation of the cover 3. Then, a pin is inserted into the positioning hole 35 and the pin hole 15 to complete the fixation of the cover 3. When the cover 3 is inserted, the elastic strip 34 is in sliding contact with the outer walls of the inner arc plate 24 and the outer arc plate 26, providing a certain pressure to ensure the stability of the filter assembly.

[0020] Working principle:

[0021] When in use, the paint mist enters the inside of the box body 1 through the ventilation groove 12 on the fixed box 11 and is blown out from the air outlet groove 16. When the air flow passes through the filtering device 2, the filtering device 2 plays a role. The sliding groove 22 on the support plate 21 cooperates with the insertion block 23, enabling the insertion block 23 to slide stably. The filter assembly composed of the inner arc plate 24, the outer arc plate 26 and the filter cotton 25 filters the paint mist. The filter cotton 25 can effectively adsorb the particles and impurities in the paint mist. The inner arc plate 24 and the outer arc plate 26 provide support and protection for the filter cotton 25;

[0022] During use, the inner arc plate 24, the filter cotton 25, and the outer arc plate 26 are regarded as a filtering component. This filtering component completes air circulation through the holes on the inner arc plate 24 and the outer arc plate 26. At the same time, the paint mist is intercepted on the filter cotton 25. By arranging the four rows of filtering components inside the box body 1 in a specific arrangement, a complete filtering device 2 is formed, that is, the filtering components in the first row close to the ventilation groove 12 are arranged at the same interval, and the three rows of filtering components in the back row are arranged in a trapezoid with the short side of the trapezoid close to the first row of filtering components. This arrangement optimizes the air flow distribution, making the paint mist pass through each filtering component more evenly. Since the first row of filtering components is evenly arranged, it can initially intercept and disperse the paint mist more evenly, reducing the uneven filtering caused by the concentration of local air flow. The trapezoidal arrangement in the back row effectively utilizes the space, increasing the coverage area of the filtering components, enabling the air flow to contact more filtering materials when passing through, and improving the sufficiency of filtering. The design that the short side of the trapezoid is close to the first row of filtering components enables the paint mist after the initial filtering in the first row to enter the filtering area in the back row more concentratedly, increasing the pressure difference of filtering, thereby improving the filtering efficiency. At the same time, this arrangement can also reduce the mutual interference between the filtering components, avoid the phenomena of air flow short circuit and backflow, and thus ensure that the paint mist can fully interact with the filtering materials. In addition, it helps to balance the loads of each row of filtering components, avoid premature saturation or excessive wear of a certain row of filtering components, extend the service life of the entire filtering device 2, and reduce the maintenance cost.

[0023] The limiting block 13 inside the fixed box 11 in the box body 1 plays a role in limiting the movement of the support plate 21, ensuring that it is difficult to sway left and right inside the fixed box 11. The elastic extrusion block 14 contacts the support plate 21. On the one hand, it provides a certain buffer and support for the support plate 21, and on the other hand, it ensures the close contact between the support plate 21 and the box body 1, reducing the leakage of paint mist. When the cover 3 is installed, the insertion strip 33 and the limiting plate 32 at the bottom of the connecting plate 31 are quickly inserted into the inside of the fixed box 11 by means of four-corner positioning to achieve the accurate installation of the cover 3. Then, a pin is inserted into the positioning hole 35 and the pin hole 15 to complete the fixation of the cover 3. When the cover 3 is inserted, the elastic strip 34 slides into contact with the outer walls of the inner arc plate 24 and the outer arc plate 26, providing a certain pressure to ensure the stability of the filtering component. The cooperation of the sliding groove 22 and the insertion block 23 in the filtering device 2 facilitates the installation and replacement of the filtering component. By uncovering the cover 3, the filtering component can be quickly replaced and extracted. The setting of the limiting block 13 and the elastic extrusion block 14 in the box body 1 improves the stability and sealing performance of the placement of the filtering device 2, and the design of the insertion strip 33, the limiting plate 32, and the elastic strip 34 of the cover 3 makes the cover 3 firmly installed while ensuring the stability of the filtering component.
