Mask

Abstract

The invention relates to a mask. The mask comprises a mask body and two ear hooks arranged on the two sides of the mask body, the mask body comprises a first upper non-woven fabric layer, a first melt-blown fabric layer, a buffer breathable layer and a first inner non-woven fabric layer which are sequentially stacked up and down, the thickness of the buffer breathable layer is not smaller than 5 mm, and the buffer breathable layer has compressibility and breathability; air guide areas are arranged on the two sides of the mask body respectively, at least one long hole is formed in each air guide area, each ear hook comprises an air guide part and a connecting part, the air guide parts are fixed to the portions, located on the peripheral sides of the air guide areas, of the back face of themask body, an air guide cavity is formed between each air guide part and the corresponding air guide area, and the long holes are communicated with the air guide cavities. The invention relates to thefield of masks, when the respiratory capacity of a human body is increased, air between a mask body and the face can flow and be exhausted through the buffering breathable layer and the air guide cavities, the storage and buffering functions on the air are achieved, and the technical problems that a mask is poor in ventilation performance and poor in air tightness are solved.

Description

technical field [0001] The invention relates to the field of masks, in particular to a mask. Background technique [0002] Mask is a kind of sanitary product, which generally refers to a device worn on the mouth and nose to filter the air entering the mouth and nose, so as to block harmful gases, odors, and droplets from entering and exiting the wearer's mouth and nose. During the special period of the new coronavirus, Masks have become a necessity for people to live, travel and work. At present, masks that can block the new coronavirus usually adopt a three-layer structure, including an upper layer of non-woven fabric, a melt-blown fabric, and a lower layer of non-woven fabric that are stacked up and down in sequence. , poor ventilation, poor air tightness and other issues. When people breathe more gas, the gas passing through the mask increases, the gas volume between the human face and the mask increases, and the air pressure increases. Due to the fixed surface area of ...

AI Technical Summary

Problems solved by technology

It solves the technical problem of poor ventilation and poor airtightness of the mask when the human body's breathing volume is increased, and gaps are prone to appear in the mask, so that part of the gas is discharged from the gap and enters the human body.
