In the present embodiment, the housing 10 includes a ventilation suction port and a ventilation outlet 13, the ventilation suction port communicates with the outside, the ventilation outlet 13 communicates with the room, and the ventilation air passage 11 communicates with the ventilation suction port. By communicating the air outlet 13, the outside air is taken into the room. Preferably, the ventilation outlet 13 is provided on the front side surface of the housing 10 and blows the wind toward the front side so that the user can intuitively feel the wind. Further, the filter assembly 20 is slidably mounted in the ventilation air passage 11 from the mounting port 12. Since the filter assembly 20 slides, a sliding groove is provided on the inner wall of the ventilation air passage 11, and the sliding groove can guide and limit the position of the filter assembly 20. The sliding groove is formed by a support protrusion provided on the inner wall of the ventilation air passage 11, and the support protrusion supports the bottom of the filter assembly 20, or the sliding groove is a concave groove provided on the inner wall of the ventilation air passage 11. be.

The filter 22 may be any one or a combination of two or more of an ABS filter, a HEPA filter, an activated carbon filter, a photocatalyst filter and the like. The filter 22 has a shape suitable for the cross section of the ventilation air passage 11 to better isolate the ventilation air passage 11 so that all the outside air entering the ventilation air passage 11 is filtered by the filter 22. Secure. For example, the filter 22 may be substantially square.

The filter support 21 has various forms. For example, in one embodiment, the filter support 21 has a substantially frame shape and is provided around the outer peripheral surface of the filter 22. In one embodiment, the filter support 21 has a grid pattern and supports one of the filtration surfaces of the filter 22. In one embodiment, the filter support 21 has a hollow box shape, and the filter 22 is incorporated in the filter support 21.

In the present invention, the filter support 21 is added, the filter assembly 20 is formed by attaching the filter 22 to the filter support 21, and the filter support 21 increases the strength of the entire filter assembly 20. Even if the filter assembly 20 collides with another member when it is pulled out, the filter 22 can be significantly reduced from being deformed and damaged.

Conventionally, a cover plate is rotatably provided on the housing 10, and after the filter 22 is installed at a predetermined position, the cover plate is rotated to cover the mounting port 12. However, since the cover plate is rotatably attached, a relatively large attachment gap is inevitably formed between the cover plate and the edge portion of the attachment port 12, and dust tends to accumulate in the attachment gap. In order to solve the above problems, in one embodiment of the present invention, the filter support 21 includes a lid portion 212 located at one end, and the lid portion 212 covers the mounting port 12. Since the filter assembly 20 is fitted to the housing 10 in a pulled-out form, even if the lid portion 212 is in close contact with the housing 10, the pull-out of the filter assembly 20 is not affected. Therefore, it is not necessary to secure a gap between the lid portion 212 and the housing 10, and the filter assembly 20 can be pushed inward at the time of assembly, and the lid portion 212 and the housing 10 can be brought into close contact with each other, whereby the mounting port 12 Can be covered and there are no gaps.

In another embodiment, the lid portion 212 may be a stopper plate additionally added on the frame body 211. In order to further enhance the covering effect, in one embodiment, the peripheral edge of the lid portion 212 extends outward to form a circular flange 2121 around the circumference, and the annular flange 2121 is provided so as to protrude from the peripheral edge of the mounting port 12. It can be guaranteed to completely cover the mouth 12.

Referring to FIGS. 5, 6 and 7, in one embodiment, the housing 10 is provided with a protruding rib 14, which extends along the circumferential direction of the mounting port 12 to form an annular shape, and the annular flange 2121. The surface of the filter 22 facing the filter 22 abuts on the protrusion rib 14. Through the installation of the protrusion rib 14, the contact area between the lid portion 212 and the housing 10 can be reduced, and by reducing the contact area, each part of the lid portion 212 is brought into close contact with the protrusion rib 14, thereby achieving a sealing effect. Can be improved.

In one embodiment, the housing 10 is provided with a recessed groove 15, the mounting port 12 is provided in the recessed groove 15, the lid portion 212 is located in the recessed groove 15, and at least one side of the lid portion 212 is the groove wall of the recessed groove 15.
