Embodiment 1

[0027] as attached figure 1 , attached figure 2 The shown embodiment PM2.5 mouth mask comprises mouth mask main body 1, filter gallbladder 2, lanyard 3, ear lanyard 31, head lanyard 32, breathing valve 4, air inlet valve 41, air outlet valve 42, breathable filter device 43, breathable ring 431, filter layer 432, clasp 433, clip 5, breathing valve includes being fixed on the inlet valve 41 on mouth mask main body 1, is fixed on the outlet valve 42 on the filter gall 2, at first breathable filter device 43 is located at In the concave cavity of the outlet valve 42, the outlet valve 42 is connected with the inlet valve 41. The installation process of the whole breathing valve 4 is simple and convenient, and the long-term use of the conventional mask can be solved by replacing the filter device 43 in the breathing valve 4. The problem of poor filtering performance of the mask, the filter gall 2 is arranged on the inner side of the mask main body 1, and the upper part of the inne...

Abstract

The invention relates to a protective mask, in particular to a PM2.5 mask, comprising a mask body, a filter lining, hanging cords and a breather valve. The hanging cords are connected to the two sidesof the mask body, the filter lining is arranged at the inner side of the mask body, the breather valve includes an intake valve fixed to the mask body, an exhaust valve fixed to the filter lining, and a breathable filtering device arranged between the intake valve and the exhaust valve; both the intake valve and the exhaust valve are of cavity structure; the intake valve and the exhaust valve arereleasably connected. The breathable filter device is arranged in a cavity of the exhaust valve; the exhaust valve is then connected with the intake valve; the whole breather valve is simple and convenient to mount; by changing the filter device in the breather valve, the problem that a conventional mask has poor filtering performance after long-term use is solved; the filter lining is arranged at the inner side of the mask body, the inner upper portion of the filter lining is provided with adjustable alar sponge pads, and therefore the inner side of the filter lining has good contact with ahuman face.

Description

technical field [0001] The invention relates to a protective mask, in particular to a PM2.5 mask. Background technique [0002] PM2.5 refers to particulate matter in the ambient air with an aerodynamic equivalent diameter less than or equal to 2.5 microns. It can be suspended in the air for a long time, and the higher its concentration in the air, the more serious the air pollution. Compared with atmospheric particles with larger diameters, PM2.5 has a small particle size, large area, and strong activity, and is easy to carry toxic and harmful substances such as heavy metals and microorganisms, and has a long residence time in the atmosphere and a long transportation distance. It has a greater impact on human health and atmospheric environmental quality. [0003] At present, the main means of protection against such ultrafine particles is to wear PM2.5 masks. However, most of the PM2.5 masks currently on the market are easy to breathe when worn, the contact surface of the...
