Description

Face mask

The present invention is related to masks.

Masks can effectively filter the air to isolate harmful substances such as bacteria, viruses, particles, and droplets, and ensure that the air inhaled by the wearer is clean. Depending on the timing and purpose of use, masks can be divided into: general masks for cleaning, surgical masks that can block more than 90% of 5-micron particles, activated carbon masks that remove odor and toxic dust, and masks that can block more than 95% of sub-micron particles of N95 masks.

Traditional and common masks are mainly in a flat state, which is convenient for stacking, storage and transportation. However, such flat masks have poor adhesion during use, cannot match the change of face shape, are prone to gaps, and put a lot of pressure on the face. , The strong airflow resistance leads to breathing difficulties, heat accumulation and other adverse conditions.

Therefore, it is necessary to provide a novel and progressive mask to solve the above problems.

The main purpose of the present invention is to provide a mask, which can effectively provide a three-dimensional space for the wearer and give the wearer a comfortable feeling.

In order to achieve the above purpose, the present invention provides a mask, comprising: a mask body, a nose bridge strip and a molding part. The mask body includes at least two crimping areas; the nose bridge strip is set on the mask body, and the nose bridge strip is for pressing on the nose; the plastic part can be arbitrarily bent and shaped by the outside world, and the plastic part is spaced from the nose bridge strip. Set on the mask body, the plastic part includes two ends and a middle section, the two ends are respectively positioned in the at least two crimping areas, and the middle section is connected between the two ends and can be connected to the two ends. The part is a fulcrum that swings freely relative to the mask body to be away from or close to the bridge of the nose.
