Description

Anti-fog mask {Anti-fog mask}

The present invention relates to a mask for preventing fogging, and specifically, to a mask to which a fan is applied.

When a person wearing glasses wears a mask, water vapor rises through the gap between the mask and the face and condensation on the cold glasses causes blurred vision. In order to solve this problem, various techniques such as putting a shape memory alloy in a mask or forming an airtight member inside the mask have been attempted.

The anti-fog mask of patent application No. 10-2010-0139782 is formed of a material such as soft iron on the part of the mask in contact with the nose as shown in FIG. 1 to minimize the outflow of exhalation through the gap between the nose. Disclosed is a pressing member 110 and 120 for maintaining the upper shape of the mask and a sponge member 130 for sealing a gap between the nose and the mask.

However, since the sponge member 130 creates a gap between the mask and the nose due to its thickness, the effect of preventing fogging is insufficient.

On the other hand, a mask with an exhaust fan has been proposed so that exhalation does not occur through the gap between the nose, but due to the limitation of the size of the fan that can be installed, exhaust as much as the amount of exhalation of the wearer is not performed, so the effect of preventing fogging is still insufficient. There is this.
