Description

[0001] The present invention relates to a mask having a sunlight and a fine dust-

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mask having a sunlight and fine dust barrier function, and more particularly, to a mask having sunlight, fine dust, and odor barrier function which improves the cleaning efficiency and greatly improves the feeling of wearing.

In general, the mask has been mainly used for keeping warm in winter or for protecting the bronchi of the elderly. However, recently, industrial development and increase of fossil fuel combustion amount have increased the amount of air pollutants generated. Especially, The air pollution is getting worse because of the yellow dust, and the demand is greatly increased regardless of the seasons and the ages.

In addition, recently, damage to the ozone layer caused by ultraviolet rays is increasing due to destruction of the ozone layer. Such ultraviolet rays not only promote skin aging, but also cause wrinkles and skin diseases. Therefore, the use of a mask for blocking sunlight is also greatly increased for this reason.

The conventional techniques related to the mask for blocking dust or sunlight will be described as follows.

First, conventional sunglasses for protecting the sunlight or a sunshade covering the face have a structure that can block the sunlight coming toward the wearer's face. However, since the nose and the mouth are not sealed, air is sucked directly through the nose and mouth, and thus the fine dust and odor scattered in the air can not be blocked.

In order to solve such a problem, an air supply device for injecting air into the hermetically closed interior of the nose and the mouth, and an exhaust device for discharging air are provided so as to prevent direct inflow of air into the mouth and nose, In this case, the nose and mouth are sealed, making it difficult to breathe and causing a problem of having a comfortable fit.

In addition, the non-woven material mask has a structure in which air around the nose and the mouth is sealed to prevent the air contaminated with fine dust and the like from being sucked directly into the nose and mouth. However, such a non-woven material mask has a problem that it is inconvenient to breathe and has a comfortable feeling of being uncomfortable.

Accordingly, in order to solve such a problem, a mask having an intake port provided with a filter for blocking contaminated air and an exhaust port for breathing has been developed. However, the mask having such a structure is still unable to solve the problem that the nose and the mouth are sealed, so that it is hard to breathe and has a tight fit.

As described above, sunglasses or face covering for conventional sunlight blocking function do not provide a function of blocking contaminated air mixed with fine dust to the user. In order to block the air polluted with sunglasses or sunshade, it is necessary to have a configuration in which the nose and the mouth are closed so as to be in close contact with the face so as to prevent the air from being pushed in. In addition, the structure of the air intake port and air exhaust port, So that there is a problem that the wearer's feeling of wearing is greatly reduced.
