Problems solved by technology

When the mask is only used for short-term wear, the elastic body such as the arched sponge is often discarded together with the mask, and the dust and oil generated by the contact between the elastic body and the skin adhere, and the phenomenon of bacterial growth is not obvious, but this method will cause more organic polymers Rubbish

specific Embodiment example 2

[0017] Specific implementation case 2, see figure 2 , A double-layer mask body 1 composed of corn fiber non-woven fabric and polypropylene electrostatic electret filter cotton has a raised fabric 2 on the upper end. The raised fabric 2 is folded along the bending line 4 toward the lower part of the inside of the mask, and the bending line 4 forms an included angle of 160 degrees at the center bonding line 433. The raised fabric 2 is heat-sealed at the center bonding line 433, and the two ends of the mask body 1 are heat-sealed in an L shape by the lower bonding line 435 and the side bonding line 434. Two silicone elastomers 3 are located in the two arches formed by the raised fabric 2. After connecting the upper and lower sides of the mask, the straps 11 pass through behind the ears and fasten behind the head.

Abstract

The present invention provides a mask. The top of the mask is provided with a protruding fabric which is turned inwards, the protruding fabric is located on the center line of the mask and the two sides of the mask and is attached and fixed to a mask body, and the protruding fabric and the mask body are provided with a cavity and an opening which are symmetrically formed between the center line ofthe mask and the two sides of the mask and can contain elastic bodies respectively. Through the cavity formed by the convex fabric, the wearing air tightness of the mask is improved, and mask shielding failure caused by gaps existing at the nose bridge is reduced and avoided; and direct contact between the elastomer for sealing and the skin is avoided, and the service life of the elastomer is prolonged.

Description

Technical field [0001] The invention relates to the field of sanitary product protection, in particular to a mask. Background technique [0002] Masks are prone to gaps in the nose, and users wearing ordinary masks will leak air due to the gaps between the bridge of the nose and the cheeks. In the related technology, the application number 2018202693889 adopts the way that the mask has protrusions, and the protrusions are turned inward parallel to the bridge of the nose. The bending of the bridge of the nose allows the inversion to fit the bridge of the nose. Although it has a certain effect, it is due to The main body is parallel and can only rely on the bending of the nose bridge to press the main body of the mask to fit the protrusion and the bridge of the nose. However, after the nose bridge is pressed, the vibration during wearing and use, the up and down movement of the mask and the loose shape of the nose bridge will eventually cause the sealing effect of the nose bridge ...
