[0017] The utility model is described in detail below in conjunction with the accompanying drawings. As shown in Figures 1 and 2, a HEPA filter detachable bracket for a fresh air blower includes a bracket frame assembly 1 and side buckles 3 and connecting buckles 4 installed around the bracket frame assembly 1, wherein the bracket frame assembly 1 includes a bracket upper frame 11 and a bracket lower frame 12, a sealing layer 13 is provided between the bracket upper frame 11 and the bracket lower frame 12, and the sealing layer 13 adopts a rubber sealing layer. Rubber gaskets 14 and filter screens 15 are alternately provided inside the bracket upper frame 11 and the bracket lower frame 12 in sequence, and the filter screen 15 adopts a framed HEPA filter screen, and a filling frame is also provided on the front side between the bracket upper frame 11 and the bracket lower frame 12. The filling frame 16 is fixed to the bracket lower frame 12 on both sides of the lower end by hand-tightening bolts, and the upper frame 11 of the bracket and the lower frame 12 of the bracket are connected and fixed on both sides by side buckles 3. The upper part of the upper frame 11 of the bracket is equipped with a connecting buckle 4. When disassembling and replacing, the upper frame 11 of the bracket is removed by opening the side buckle 3 and the connecting buckle 4, and then the filling frame 16 is removed from the bracket lower frame 12, so that the rubber gasket 14 and the filter screen 15 are loosened, and the filter screen 15 to be replaced is taken out and replaced with a new filter screen 15, and then the filling frame 16 is installed in the bracket lower frame 12, so that the filter screen 15 can be replaced more conveniently.

[0018] In this embodiment, specifically, the filling frame 16 is an aluminum alloy frame or a stainless steel frame.

[0019] In this embodiment, specifically, the filling frame 16 plays a role in pressing the rubber gasket 14 and the filter screen 15 tightly.

[0020] How it works

[0021] In the utility model, during installation, the user fixes the lower frame 12 of the bracket to the fresh air fan 2, and fixes the upper frame 11 of the bracket to the fresh air fan 2 through the connecting buckle 4, thereby fixing the bracket frame assembly 1 at the air inlet of the fresh air fan 2, and the bracket frame assembly 1 plays the role of installing and fixing the filter 15.

[0022] Utilizing the technical solution described in the utility model, or those skilled in the art designing similar technical solutions inspired by the technical solution of the utility model to achieve the above-mentioned technical effects, all fall within the protection scope of the utility model.
