[0002] The air delivery device is a ventilation device provided for a spray booth. The early device has poor filtering effect, and impurities are easily mixed in during the air delivery process, resulting in an impact during operation. Based on this, a filtering component needs to be set in the ventilation duct during use to filter the air. Since it is necessary to filter the particulate matter in the gas, a large amount of particulate matter accumulates on the surface of the filter cloth, thereby reducing the filtering efficiency. At this time, the filter cloth needs to be replaced. However, the existing filtering device is more cumbersome to replace and is not often replaced, resulting in a reduction in filtering efficiency.

[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present invention.

[0022] In the description of the present invention, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "periphery", etc. indicating the orientation or positional relationship are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation to the present invention.

[0023] Please refer to Figure 1 and 3 As shown, the present invention is a filter assembly convenient for replacing the filter cloth, which includes a rectangular frame 1 fixed in the ventilation channel, and a peripheral edge is provided on the circumferential side of one surface of the rectangular frame 1, and a metal mesh 11 is provided on the rectangular frame 1 within the peripheral edge 10. A filter cloth 12 is provided on one side of the metal mesh 11. During use, a fixing member 2 is cooperatively connected to the peripheral edge 10, and a pressing frame 13 is controlled by the provided fixing member 2 to abut against the filter cloth 12, thereby controlling the filter cloth 12 to closely adhere to the metal mesh 11.

[0024] As Figure 2 , in order to facilitate the fixing of the fixing member 2 and use the fixing member 2 to control the pressing frame 13 to abut against the filter cloth 12, the fixing member 2 includes an L-shaped plate 20 fixed to the inner side wall of the peripheral edge 10. A clamping block 21 is provided at one end of the L-shaped plate 20 and abuts against the port of the peripheral edge 10. A fixing bolt 22 is provided on one side of the L-shaped plate 20, and a threaded hole A connected to the fixing bolt 22 is provided on the inner wall of the peripheral edge 10. A locking bolt A 23 with its end abutting against the pressing frame 13 is provided on the other side of the L-shaped plate 20.

[0025] On the above basis, as Figures 4 - 5 In order to improve the better adhesion of the filter cloth 12 to the metal mesh 11, three pressing plates 14 are provided at equal intervals in the vertical direction of the pressing frame 13, and the pressing plates 14 are attached to the filter cloth 12; at the same time, in order to facilitate the installation of the pressing plates 14, the present application respectively provides an L-shaped fixing plate 131 on both sides of the pressing frame 13. A locking bolt B 132 is threadedly connected to the L-shaped fixing plate 131, and the end of the locking bolt B 132 abuts against a pressing plate 14; at the same time, both ends of the pressing plate 14 respectively abut against one side of the rectangular frame 1.

[0026] It can be known that, for the convenience of installing the pressing plate 14 and the pressing frame 13, a positioning sleeve B141 for inserting the locking bolt B132 is provided on one side wall of the pressing plate 14; at the same time, a positioning sleeve A130 for inserting the locking bolt A23 is provided on one side wall of the pressing frame 13.

[0027] Based on the above, the pressing mechanism for controlling the filter cloth 12 to closely adhere to the metal mesh 11 in the present invention is decomposed into a pressing plate 14 and a pressing frame 13, reducing the weight of a single part, and thus facilitating the distributed installation of the pressing plate 14 and the pressing frame 13 during use.

[0028] At the same time, for the convenience of installing the filter cloth 12 during use, such as Figures 6 - 7 , during use, it is necessary to control one end of the filter cloth 12 to be pre-fixed at the top of the pressing frame 13. Therefore, a fixing structure for fixing and clamping the filter cloth 12 is provided at the top of the pressing frame 13. The fixing structure includes a pressing rod 16. A convex block 161 is provided on one side of the pressing rod 16. A locking bolt C162 is threadedly penetrated through the convex block 161. A threaded hole B for cooperating with the locking bolt C162 is provided on the pressing frame 13. Thus, one end of the filter cloth 12 is inserted between the pressing rod 16 and the pressing frame 13 during use.
