Description
Technical field
The utility model relates to daily hygiene articles for use field, is specifically related to dry wet double-filtration mouth mask.
Background technology
Mouth mask has certain filtration to the air entering lung, when respiratory infectious disease is popular, in the environment that dust etc. pollutes during operation, wears masks and has extraordinary protective effect.Use can be worn in many people, airless place, in outdoor sport, for resisting dust storm and cold, or there being activity in air-polluting environment, putting on mouth mask and there is protective effect; And traditional mouth mask filtering efficiency and air transmission coefficient exist very big contradiction, want to improve filtering efficiency, only have the thickness increasing filter material, improve filter material density, but will air drag be increased like this, make wearer easily produce the senses of discomfort such as unsmooth breath.
Summary of the invention
The purpose of this utility model is to provide dry wet double-filtration mouth mask, this mouth mask sealing and good filtration effect, and breathes smooth and easy.
Dry wet double-filtration mouth mask, comprise cover body, be located at the filter ventilation device on cover body, be located at the soft sealing strip on cover body week edge, described filter ventilation device, comprise ventilation seat, be located at the vent hood of ventilation seat outer end, be attached at the dryness filter inside vent hood, be installed with the spacer ring inside dryness filter, be attached at the moist filter inside spacer ring, be installed with the hollow pressure ring inside moist filter, described hollow pressure ring both sides are provided with buckle, described ventilation seat is provided with L-type catching groove and is clasped, described dryness filter is by non-woven fabrics, cotton or active carbon fibre dimensional fabric are formed, described moist filter is made up of the filter membrane that fibre density is lower, filter membrane material is non-woven fabrics, cotton or active carbon fibre dimensional fabric, described moist filter is immersed with scavenging solution.
The hollow center of described spacer ring and hollow pressure ring is provided with connection strap, prevents filter central region sinking, and described vent hood is provided with multiple passage.
Owing to being provided with said structure, the filter membrane that this mouth mask utilizes fibre density lower, filter membrane increases liquid, make to produce moisture film between filter membrane fiber, moisture film can stop and the impurity such as the dust in absorbed air to greatest extent, but the turnover of not easily blocks air, thus reaches and not only ensure filtering efficiency but also do not affect air transmission coefficient, sealing and good filtration effect, can Chalk-dust filtering, PM2.5 and toxic gas.

Detailed description of the invention
As Fig. 1, Fig. 2, Fig. 3, Fig. 4, shown in Fig. 5, dry wet double-filtration mouth mask, comprise cover body 1, be located at the filter ventilation device on cover body 1, be located at the soft sealing strip 2 on cover body 1 week edge, described filter ventilation device comprises ventilation seat 3, be located at the vent hood 31 of ventilation seat 3 outer end, be attached at the dryness filter 32 inside vent hood 31, be installed with the spacer ring 33 inside dryness filter 32, be attached at the moist filter 34 inside spacer ring 33, be installed with the hollow pressure ring 35 inside moist filter 34, described hollow pressure ring 35 both sides are provided with buckle 36, described ventilation seat 3 is provided with L-type catching groove 37 and coordinates with buckle 36, described moist filter 34 is that the filter membrane that fibre density is lower is formed, described moist filter 34 is immersed with scavenging solution.The hollow center of described hollow pressure ring 35 is provided with connection strap 38, and prevent dryness, moist filter 32,34 central region sinking, described vent hood 31 is provided with several passage 39.During use, dryness filter 23 2 is affixed on vent hood 31, then buckle spacer ring 33 and compress dryness filter 32, again moist filter 34 is affixed on inside spacer ring 33, buckle spacer ring 33 again and compress moist filter 34, and moist filter 34 can soak scavenging solution in advance, also drip with dropper again after can installing and sprinkle or spray upper scavenging solution, then buckle cingulum 4 just can use, simultaneously, because filter disc fibre density used is lower, so larger resistance can not be produced to the turnover of air, thus make breathing more smooth and easy.
