Detailed description of the invention
By reference to the accompanying drawings the present invention is described in further detail below by detailed description of the invention.The application can realize with multiple different form, is not limited to the embodiment described by the present embodiment.There is provided the object of following detailed description of the invention to be convenient to the clearer understanding thoroughly of the application's disclosure, wherein the words of the indicating position such as upper and lower, left and right is only for shown structure position in respective figure.
But those skilled in the art may recognize that one or more detail describes and can be omitted, or can also adopt other method, assembly or material.In some instances, some embodiments do not describe or are not described later in detail.
In addition, feature described herein, enforcement or feature can also combine in one or more embodiments in any suitable manner.
Embodiment one:
Mask main body as shown in Figure 1, comprises the first filter course 1, Electrospun nano-fibers layer 2 and the second filter course 3 that superpose successively.
First filter course 1 can be chosen as the polypropylene spun-bonded non-woven fabrics of grammes per square metre 15-30g/m2.This material has that intensity is high, wearability better and the feature of good air permeability.The Electrospun nano-fibers layer 2 of this layer material to mouth mask inside plays good protective action, and very little on the respiratory resistance impact of mask main body, good wearability ensure that use procedure mouth mask is not easily worn.
Nanofiber and non-woven fabrics are existingly undertaken combining by method of electrostatic spinning and the material formed for a kind of by this Electrospun nano-fibers layer 2, that such as commonly uses has PVA or PA6 and polyester continuous filament fabric hot rolled nonwoven fabrics (polyester continuous filament fabric hot rolled nonwoven fabrics and terylene (PET) spun-bonded continuous yarn non-woven fabrics, be called again PET spun-bonded continuous yarn non-woven fabrics, belong to the one of continuous yarn non-woven fabrics, it is formed by spun-bonded hot rolling by without several continuously polyester filament.) carry out compound by modes such as injections.Wherein PVA is that polyvinyl alcohol is called for short, and PA6 is the abbreviation of polyamide 6.
Because nanofiber has great specific area and surface-to-volume ratio, it has a lot of micropore on the net felt be shaped, therefore have very strong absorption affinity and good filterability, barrier, cohesive and heat insulating ability, effective filter diameter is less than or equal to the fine particle of 2.5 microns.
Electrospun nano-fibers layer 2 is extend along direction wavy.Namely as shown in Figure 1, Electrospun nano-fibers layer 2 folds continuously along a direction, after folding, Electrospun nano-fibers layer 2 be wavy along a direction extension, after making whole folding of material, the surface area of material increases, when same flow, its expiratory resistance is reduced, and makes mask main body have higher gas permeability.
Further, the angle in adjacent two faces of waveform is 30 ~ 60 °, and crest and trough distance are 3 ~ 5mm, and as shown in Figure 1, the angle between face A and face B is 30 ~ 60 °, and the difference in height between crest D and trough C is 3 ~ 5mm.
Certainly, in other embodiments, the angle between adjacent two faces also can select other angle, as being other angles in acute angle or obtuse angle.Crest and trough distance also can carry out flexible design according to actual needs.
Further, the second filter course 3 can be the soft polypropylene spun-bonded non-woven fabrics of grammes per square metre 15 ~ 30 grams/m, if respiratory resistance is 0.05 ~ 0.15mmH
2the soft polypropylene spun-bonded continuous yarn pro-skin nonwoven layer of O.This layer material comparatively other layer material has soft comfortable, smooth surface, without pile, does not fall the features such as bits, is suitable for as skin-friendly layer.
In the present embodiment, Electrospun nano-fibers layer 2 has good PM2.5 strainability and good gas permeability.First filter course 1 and the second filter course 3 ensure that the serviceability that mouth mask is good, and as in order to ensure wearing comfort, it is skin compatible material that the second filter course adopts.In order to ensure the service life of mouth mask, what the first filtering material adopted is the wearing layer with wearability, and this materials at two layers is lower on the impact of mask main body respiratory resistance simultaneously.The mask main body stacked up by this three kinds of materials, its PM2.5 filter efficiency is 99.9999%, and respiratory resistance is less than 3.0mmH
2o, can as PM2.5 anti-dust respirator, and antivirus protection mouth mask.
In other examples, the first filter course 1 can also be grammes per square metre is 20 ~ 30 grams/m, and expiratory resistance is 0.1 ~ 0.2mmH
2the wood pulp paper of O.
In other examples, the second filter course 3 can also be grammes per square metre is 20 ~ 30 grams/m, and expiratory resistance is 0.1 ~ 0.2mmH
2the wood pulp paper of O.
Embodiment two:
A kind of mask main body, as shown in Figure 2, the difference of this embodiment and the first embodiment is that the present embodiment comprises the hole drilling ventilation film 4 that one deck has air-vent, hole drilling ventilation film 4 is between the first filter course 1 and Electrospun nano-fibers layer 2, this film has the performance of permeable watertight, also has certain elasticity in addition.
Further, hole drilling ventilation rete 4 can select grammes per square metre to be 20 ~ 30g/m
2hole drilling ventilation rete 4.
Further, the hole on hole drilling ventilation rete 4 is equally distributed bellmouth, and the upper hole in this hole is aperture, and small-bore is 0.5 ~ 1mm, and lower opening is macropore, and large aperture is 1 ~ 2mm.
Further, bellmouth density can be every square decimeter of 20 ~ 30 holes.This equally distributed bellmouth makes hole drilling ventilation film have lower expiratory resistance.
Certainly, in other embodiments, the shape of air-vent and the density of distribution and bellmouth and aperture also can be arranged according to demand flexibly.
Because hole drilling ventilation film has certain elasticity, compensate for Electrospun nano-fibers layer 2 poor flexibility, the problem that impact resistance is weak, certain protective effect is served to Electrospun nano-fibers layer 2.
Owing to adding hole drilling ventilation rete 4, this mask main body can resist the blood of 160mmHg or the impact of other harmful liquids, this material may be used for preventing outside liquid from penetrating mouth mask at medical field, the phenomenon entering respiratory system occurs, and may be used for the droplet infection preventing patient body fluid or blood splashing from causing at medical field.
Embodiment three:
A kind of mask main body, as shown in Figure 3, the difference part of the present embodiment and embodiment two is that hole drilling ventilation film 4 is between Electrospun nano-fibers layer 2 and the second filter course 3.
Embodiment four:
The present embodiment four provides a kind of mouth mask, and this mouth mask comprises mask main body and wears portion, and this is worn portion and is connected with mask main body, and mouth mask is worn on head by the portion of wearing by user, and wherein the portion of wearing can for being linked with or other forms.
The mask main body that the present embodiment four uses is the mask main body shown in above-mentioned any embodiment.
Above content is in conjunction with concrete embodiment further description made for the present invention, can not assert that specific embodiment of the invention is confined to these explanations.For general technical staff of the technical field of the invention, without departing from the inventive concept of the premise, some simple deduction or replace can also be made.
