In addition, carbon nanoballs (CNB) can be used to cleanly remove the smell of kimchi, tobacco, and fishy smell with excellent deodorizing power.

A yellow sand removal filter or a yellow sand removal filter member is used to remove yellow sand in the air. Yellow dust refers to sandy soil that is blown up by the wind and spreads into the atmosphere, covers the sky, and then gradually falls. Since the main problem in yellow dust is fine dust and ultra-fine dust, the yellow dust filter or the yellow dust removal filter member is a H13 or higher HEPA filter member that can filter fine dust and ultra-fine dust with a concentration of 300 μg/m or more. It is reasonable to use them together.

The radon removal filter or radon removal filter member exists in building materials such as soil, concrete, gypsum board, and asbestos slate, and is used to remove radon, a colorless and odorless gas that is generated when radium is nuclear fission in soil, rocks, or water. As an example, a wolfa filter or the like may be used.

An antibacterial filter or an antibacterial filter member is used to suppress bacterial propagation. In this case, nano-silver may be coated or used by adding nano-silver particles when forming a network with resin.

In this case, a gap may occur between the stroller 30 and the cover part 100 in the covered cover part 100, and external air is introduced through the gap, so that the effect of the filter member 500 may be reduced. . In this case, the effect of the filter member 500 can be increased by minimizing the gap between the stroller 30 and the cover part 100 through the tightening means 130 .

In addition, the cover part 100 may be designed and formed to fit the structure of the baby carriage 30 coupled to minimize the gap between the ultra-fine dust removal baby carriage cover 10 coupled to the baby carriage 30 . For example, the cover part 100 may have holes such as a handle fitting hole and a wheel frame fitting hole to reduce a gap generated by a frame such as a handle and a wheel of the stroller 30, and the holes are tightened. A band or the like may be formed. A re-adhesive sealing tape formed in a predetermined area (eg, about 10 to 15 cm in width) may be formed around the cover part 100 . That is, when the cover part 100 is combined with the stroller 30, the effect of the filter member 500 for purifying the air flowing into the stroller 30 by minimizing the gap with the stroller 30 can be improved. have. The sealing tape may include a mucous material or the like. In order to minimize the gap generated when the cover part 100 and the stroller 30 are coupled, the ultrafine dust removal stroller cover 10 according to an embodiment of the present invention includes the cover part rubber magnet formed in the cover part and corresponding thereto. It may include a rubber magnet for a stroller that can be attached to a specific position of the stroller 30 to be combined. The user attaches the rubber magnet for the stroller to a desired position of the stroller 30 and then combines it with the rubber magnet of the cover portion of the cover portion 100, thereby creating a gap that may occur when the cover portion 100 and the stroller 30 are combined can be minimized. The rubber magnet of the cover part and the rubber magnet for a stroller have elasticity and flexibility, so the gap is minimized during bonding.

According to an embodiment of the present invention, the efficiency of the filter member can be increased by minimizing the gap between the stroller 30 and the cover part 100 .

10 is a view for explaining the formation position of the ventilation unit 300 according to an embodiment of the present invention.

Referring to FIG. 10 , the ventilation part 300 may be formed in various parts of the cover part 100 .

The ventilation unit 300 may be formed in the front direction of the seat of the stroller 30, which is the main breathing direction of the infant riding in the stroller 30 .

External air may be rapidly introduced from the moving direction of the stroller 30 , and for this reason, the efficiency of the filter member 500 may be reduced. In this case, the ventilation unit 300 is formed on both sides of the stroller 30 outside the main traveling direction of the stroller 30 to increase the efficiency of purifying the inlet air through the filter member 500 .

The ventilation unit 300 may be a plurality of ventilation units 300 formed in the front direction of the seat of the stroller 30 and in the direction of both sides of the stroller 30 . In this case, since each venting part 300 is formed in plurality, the burden on each filter member 500 is reduced compared to when one venting part 300 is formed on one side of the filter member 500 . can increase the effect of
