[0027] To make the objectives, technical solutions, and advantages of the embodiments of the present utility model clearer, the technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Apparently, the described embodiments are some, but not all, of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the scope of protection of the present utility model.

[0028] This application provides a dust removal and purification device box for the air return opening in a clean operating room, which will be described in detail below. It should be noted that the description order of the following embodiments does not limit the preferred order of the embodiments of this application. And in the following embodiments, each embodiment has its own emphasis. For parts not detailed in a certain embodiment, reference can be made to the relevant descriptions of other embodiments.

[0029] To solve the technical problem of low ventilation efficiency of the dust removal and purification device box at the air return opening in the prior art, an embodiment of this application provides a dust removal and purification device box for the air return opening in a clean operating room. The following will be elaborated in detail.

[0030] As shown in Figures 3 to 6 a dust removal and purification device box for the air return opening in a clean operating room includes

[0031] a box body 1, and a face frame 2 is arranged on the inlet of the box body 1;

[0032] a screen mask 5, which is arranged at the front end of the face frame 2, and the screen 52 surface is suitable for primary filtering of the air entering the box body 1;

[0033] The screen mask 5 includes an outer frame 51, a screen 52, and a plurality of pressing strips 53;

[0034] A pressing groove for accommodating the pressing strip 53 is formed on the outer frame 51. The screen 52 is located on the front side of the outer frame 51, and the screen 52 is pressed into the pressing groove by each pressing strip 53 so that the screen 52 is fixed on the front side of the outer frame 51.

[0035] In this embodiment, as shown in Figure 6 the frame is a rectangular frame structure and is formed by splicing four aluminum profiles.

[0036] Specifically, as an optional implementation manner in this embodiment, as shown in Figure 4 Figure 5 the outer frame 51 is connected with a cover plate 54, and the cover plate 54 is suitable for wrapping the front end face and the surrounding side faces of the outer frame 51.

[0037] The cover plate 54 is a sheet metal part, and the cover plate 54 and the frame are connected and fixed by countersunk head screws.

[0038] Specifically, as an alternative implementation in this embodiment, as Figure 6 shown, 4 magnets 55 are fixed inside the outer frame 51. The magnets 55 are adapted to adsorb the face frame 2 so that the mesh mask 5 is fixed inside the face frame 2.

[0039] Corresponding vertical plates are arranged inside the face frame 2. The vertical plates are used to limit the depth of installation of the mesh mask 5 into the face frame 2. The magnets 55 adsorb to the vertical plates, fixing the mesh mask 5 inside the face frame 2.

[0040] Specifically, as an alternative implementation in this embodiment, as Figure 4 shown, a medium - efficiency filter screen 42 is installed inside the face frame 2.

[0041] In this embodiment, a plurality of hook - type pressing blocks are arranged inside the face frame 2. The medium - efficiency filter screen 42 is fixed inside the face frame 2 through the hook - type pressing blocks.

[0042] In the present utility model, the mesh 52 is directly fixed and tightened by pressing strips 53 on the frame, which is very convenient for disassembly and assembly. The mesh 52 can be a metal mesh, which can ensure both the ventilation rate and strength.

[0043] For the air return port dust - removing purifier box of the present utility model, instead of installing the previous primary - efficiency filter screen and using a hollow cover plate 54, a mesh 52 is directly used as the panel and as the primary - efficiency filter, greatly improving the air intake rate of the entire box body 1 and the ventilation efficiency of the operating room.
