Abstract

The utility model relates to a with the good mask of face laminating nature. This mask includes the mask body, the mask body includes skin and the inlayer that comprises ventilative flexible fiber material, be equipped with the cassette that constitutes by flexible multicellular metal foil between skin and the inlayer, cassette the average pore size is 0.05-10 micron. Owing to be equipped with the cassette that comprises flexible multicellular metal foil between skin and the inlayer, flexible multicellular metal foil has a plastic deformation ability, can with wearing facial fine laminating, reduce the gap between mask and the face to reach better filter effect. Cassette the average pore size is 0.05-10 micron, and mask's filter fineness is guaranteed to most dust in can filtered air.

Description

Mouth mask

Technical field

The utility model relates to a kind of mouth mask, particularly relates to the mouth mask of band filter.

Background technology

Mouth mask, as a kind of amenities, generally refers to and is worn over nose and mouth for filtering the air of turnover mouth and nose, to reach the apparatus of the grit of blocking harmful, gas, spittle turnover wearer mouth and nose.

That pollutes along with industrialization increasingly sharpens, and the impact of PM2.5 particle on human health contained by the haze in air more increases the weight of, and air filtering type mask is then the routine use the largest class that this case relates to.

The structure of air filtering type mask should be divided into two large divisions, one is mask body structure, and another is filter material part, for the filter material of good air filtering type mask, following three conditions should be possessed: one is can be well closely sealed with user's face, and filter efficiency is high; Two is that respiratory resistance is little; Three to be that material contacts with user comfortable.

The cotton cloth respirator of present market and medical mask are structurally because the adaptation of the problem of material and human face is poor, and many harmful particles all enter respiratory tract by mouth mask and the gap of face; Moreover because mostly filter material is mechanical fabric or common filter material, very limited for micro particle filtering ability in air, filter material is difficult to ensure filter effect in technique, the method increasing filter effect unique is needed to increase thickness exactly, and the side effect increasing thickness allows user feel exactly, and respiratory resistance is very large, and wear uncomfortable, simultaneously, because the composition of the design of mouth mask and filter material, also be difficult to really clear up filter material and change, thus the filter effect of filter material can reduce with service time, and secondary pollution is caused to user's breathing.

Utility model content

Technical problem to be solved in the utility model to provide a kind of mouth mask good with adorning oneself with facial stickiness.

This mouth mask comprises mask body, and described mask body comprises the skin and internal layer that are made up of ventilative flexible fibrous material, is provided with the filter be made up of flexible, porous metal forming between described skin and internal layer, and described filter average pore size is 0.05 ~ 10 micron.Owing to being provided with the filter be made up of flexible, porous metal forming between outer and internal layer, flexible, porous metal forming has plastic deformation ability, well can fit, reducing the gap between mouth mask and face, thus reaching better filter effect with adorning oneself with face.Filter average pore size is 0.05 ~ 10 micron, can most of dust in filtered air, ensures the filtering accuracy of mouth mask.

Further, described filter is the thin slice that forms of a kind of metal polyporous material that is matrix phase by the metal simple-substance of solid solution alloy, face-centred cubic structure or the metal simple-substance of body-centered cubic structure preferably, and its thickness is 5 ~ 200 microns, porosity 15 ~ 70%.The filter of this material has folding not fragile, and thinner thickness can ensure good gas permeability.

Detailed description of the invention

Mouth mask as shown in Figure 1, 2, it comprises mask body 1, mask body 1 comprises outer 2 and internal layer 3, outer 2 or the top edge of internal layer 3, left hand edge or right hand edge offer a filter handling opening 5, and arrange a closing structure 6 on opening 5, closing structure 6 can be set to plastics and draw rail, VELCRO or other soft compact structure.Internal layer 3 left hand edge is arranged on for demonstration with opening 5 and closing structure 6 in Fig. 2.In addition, adjustable length cover band 7 is provided with in mask body 1 both sides.Outer 2 and internal layer 3 adopt cotton fabric to make, consider that ergonomic designs is arc in shape, better can fit with user's face, and utilize the cover band 7 of adjustable length to regulate according to the needs of user mask body 1 to fit facial elasticity.Filter 4 quality is soft simultaneously, can by user's face contour generation deformation, and filter 4 has closing structure 6 after putting into mask body 1, thus ensures the gas percent of pass of mouth mask and user's face laminating degree and filter, improves mouth mask filtering accuracy.

As shown in Figure 2, mask body 1 is designed with opening 5, can design in technique upper shed 5 and all can at outer surface 2 or inner surface 1, also can design in the both sides of mask body 1 or upside, only need with the bottom of inner surface 3 is completely closed, filter 4 loading port cover body 1 can be laid mask body 1 outer surface 2, for convenience's sake, the design size of opening 5 should make filter 4 normally load and to dismantle; Filter 4 is by opening 5 loading port cover body 1, closed by closing structure 6, the recycling micron-sized thickness of filter 4 and plasticity, coordinate the adjustment of mask body 1 ergonomics arcuate profile and cover band 7, fit with user's face contour and the plastic deformation produced, thus complete the laminating with user's vertical facial dimension.

The filter 4 of this mouth mask adopts applicant's earlier application number to make for the flexible, porous metallic film provided in the patent of invention of 2014106089803.The average pore size of this flexible, porous metal foil is specially 0.05 ~ 4 micron, and porosity is 30 ~ 70%, and thickness is 10 ~ 50 microns.

In actual use, user can select in the quantity loading port cover body 1 of filter 4 according to actual needs, and this mouth mask according to use occasion and time, can be changed filter 4 and clean, and reuses after mask body 1 is capable of washing.
