Abstract

The invention discloses an effective and low-resistance mask. The mask comprises a mask body and an elastic band connected with the mask body, wherein the mask body comprises a concave supporting frame, a filtering layer, supporting layers and a sealing ring, wherein the filtering layer and one supporting layer are arranged on the side, where the outer surface of the supporting frame is arranged; the other supporting layer and the sealing ring are arranged on the side, where the inner surface of the supporting frame is arranged; a plurality of small holes are formed in the supporting layers; a first filtering layer in the filtering layer and a first supporting layer in the supporting layers are arranged on the side, where the outer surface of the supporting frame is arranged; the supporting frame, the first supporting layer and the first filtering layer are sequentially attached to one another; a second supporting layer in the supporting layers is arranged on the side, where the outer surface of the first filtering layer is arranged; the second supporting layer is attached to the first filtering layer. By the mask with the structure, the resistance during breathing of a user is reduced while relatively high efficiency of filtration is guaranteed.

Description

technical field [0001] The invention relates to a mask, in particular to a high-efficiency and low-resistance mask. Background technique [0002] The mask mainly plays a protective role, and can isolate the human respiratory system from the external environment to a certain extent, thereby protecting the human respiratory system. The protective mask forms a space sealed with the face by covering the mouth, nose and chin of the person, and the polluted air is forced to pass through the filter by the person inhaling. The body of the mask is usually made of anti-particulate filter material, fixed by headband or ear strap, and the seal of the face and nose is usually shaped with the help of metal nose clips. The Chinese utility model patent with the authorized notification number CN202476507U disclosed "a three-dimensional cup cover" on October 10, 2012. There is a concave support frame in the middle, the filter layer is a filter cotton layer, the non-woven fabric layer includ...
