Embodiment 1

[0020] Example 1, such as figure 1 Shown, mouth mask body 05 is made up of mouth mask surface layer 04, mouth mask filter layer 03, mouth mask breathable layer 12, and mouth mask composite lining layer 08. Mask top layer 04 is for fixing mask body 05 effect. Mask filter layer 03 uses mask filter material, which functions to filter air impurities and harmful substances, and purify the air. Air-permeable layer 12, separating filter layer 03 and mouth mask composite inner lining layer 08, forms the gas circulation channel of support space, gathers the air passing through mask filter layer 03, can make full use of the use area of ​​filter layer 03, and air-permeable layer 12 lays supportable For breathable materials, such as structural materials such as woven wire mesh with a thickness of more than 1MM, the material is selected from anti-condensation materials or the surface is treated with anti-condensation to prevent or reduce the condensation phenomenon of the material when it...

Embodiment 2

[0022] Example 2, such as image 3 Shown, mouth mask body 21 is made up of mouth mask surface layer 24, mouth mask filter layer 23, mouth mask breathable layer 25, mouth mask composite lining layer 26. The air-permeable layer 25 is provided with a hollow area 22, and the hollow area 22 is not provided with air-permeable materials, which does not affect the use of the mask. Composite inner liner 26 is made up of mouth and nose area lining 30, peripheral portion lining 28, peripheral portion lining 32; Air-permeable material; the connecting portion 29 connecting the nose and mouth area lining 30 and the peripheral lining 28, and the connecting portion 31 of the peripheral lining 32 are respectively overlapped and connected, and the breathable sheet 26 can be installed and disassembled through the connecting portion 29 or the connecting portion 31. The air-permeable layer 25 can be connected with each non-breathable lining of the mouth mask composite lining 26 as an integral str...

Embodiment 3

[0024] Example 3, such as Figure 5 As shown, both sides of the mouth and nose area lining sheet 44 of the composite liner breathable material have a peripheral non-breathable lining sheet 42 and a peripheral portion non-breathable lining sheet 42 respectively, and the mouth and nose area lining sheet 44 upper end of the composite lining layer breathable material Extend to upper mouth mask body wrapping place 43, the nose and mouth area liner 44 lower end of composite liner breathable material extends to mask body lower wrapping 41. The upper and lower ends of the mouth and nose area lining 44 of the composite liner breathable material in this embodiment extend to the edge of the mask body respectively, and can also be extended to the edge of the mask body with a single upper end or a single lower end during practical application.

Abstract

The invention provides a composite liner mask which comprises a mask body and slings. A breathable layer is arranged below a filter layer of the mask body, and a composite liner layer below the breathable layer is composed of an oro-nasal region breathable material liner in the middle and a non-breathable material liner at the periphery of the oro-nasal region breathable material liner. Due to thebreathable layer below the filter layer of the mask body, the usable area of the filter layer of the mask can be sufficiently utilized, a respiration channel is provided for the oro-nasal region breathable material liner in the center through the composite liner layer below the breathable layer, the non-breathable peripheral liner is used for reinforced sealing, and the whole mask has the advantages that the structure is simple, the breathability is improved, and the sealing effect is good.

Description

technical field [0001] The invention relates to a mask, in particular to a mask with a composite liner. Background technique [0002] Due to air pollution in the living environment, people need to wear masks to protect their health when going out. Commonly used masks are divided into two types: hemispherical and flat. The area of ​​the filter layer used in the mask is small, the overall seal is not good, and the use effect of the mask is limited. Contents of the invention [0003] The object of the invention is to make up for the deficiencies in the prior art and provide a composite liner / planar mask for preventing air leakage. A breathable layer is provided below the filter layer of the mask body. On the basis of fully using the effective area of ​​the filter layer of the mask, the nose and mouth area is utilized. The lining and peripheral lining are made of materials with different air permeability to form a composite lining. The mouth and nose lining provides breathing...
