Abstract

The utility model relates to a mask, particularly an air filtering mask for nasal breathing. The air filtering mask is provided with a water storing sponge, and both sides of a mask sleeve are respectively provided with a filtering cavity; a bent path is arranged inside an adsorbing column of the filtering cavity, while the inner and the outer sides of the adsorbing column are provided with an inner and an outer hard air tubes which are communicated with the bent path; the mask sleeve is provided with a moisture barrier layer and two nose clip supporting columns arranged inside the moisture barrier layer, so that the utility model has favorable air filtering effect and is comfortable for being worn on mouth and nose.

Description

The air filtration mouth mask

The utility model relates to a kind of mouth mask, especially refers to the air filter housing that nasal respiration is used.

At present, common mouth mask (covering mouth, nose simultaneously) mainly is with multi-layered gas-permeable gauze (or therebetween cotton), though gauze layer can block with absorbed air in a part of dust, even some bacteriums in the isolated space, still, mouth, nasal septum the gauze layer breathe air and are felt to breathe obstructed, especially in respiratory, after gauze was soaked, moisture sticked near the skin mouth, the nose, and the people is felt under the weather.

In view of this, the purpose of this utility model is to be communicated with outside the cover and the air filtration chamber in the seal closure being provided with of mouth, nose both sides, has both breathed filtered fresh air, feels comfortably cool again.

The purpose of this utility model is achieved in that a kind of air filtration mouth mask comprises mouth mask cover and bolt taut band, it is characterized in that: the mouth mask cover is made up of vapour barrier, sealing adsorption layer, interior contact lining and two nose clip support columns, wherein sealing adsorption layer is I shape layer, in the middle of its straight section is bonded in the vapour barrier, and upper and lower crosspiece is bonded in upper and lower edge in the vapour barrier, interior contact lining is bonded in the upper and lower crosspiece of sealing adsorption layer, it is the projection cylindricality that two nose clips support, and is connected on the vapour barrier inner face of sealing adsorption layer straight section both sides; Both sides at the mouth mask cover are respectively equipped with filter chamber, this filter chamber is made up of vapour barrier, adsorption column, prominent some hardboard, level and smooth hardboard and inside and outside strong-willed pipe, wherein adsorption column has curved passage in it, and relative prominent some hardboard and level and smooth hardboard are separately positioned on the two side of curved passage, inside and outside strong-willed pipe is plugged on respectively on the curved accordingly passage of the inside and outside sidewall of adsorption column, and vapour barrier is bonded in the adsorption column outer surface.

Above-mentioned sealing adsorption layer is that soft sponge is made.

It is that hard rubber is made that above-mentioned nose clip supports.

The vapour barrier of above-mentioned mouth mask cover is narrow or wide rectangle.

The adsorption column of above-mentioned filter chamber is that soft sponge is made, and sponge needs retaining.

Curved passage is a shape in the adsorption column of above-mentioned filter chamber.

Because adopt such scheme: air filtration is effective, be worn over mouthful, comfortable on the nose, ventilation is smooth.

Below in conjunction with drawings and Examples the utility model is further specified.

Fig. 1 the utility model exemplary embodiments structural representation.

Fig. 2 the utility model exemplary embodiments A-A generalized section.

Among the figure: 1, mouth mask cover 11, vapour barrier 12, sealing adsorption layer 13, interior contact lining 14, nose clip support column 2, filter chamber 21, vapour barrier 22, adsorption column 221, curved passage 23, prominent some hardboard 24, level and smooth hardboard 25, sterilization layer 26, refrigerant spice layer 27, interior strong-willed pipe 28, outer strong-willed pipe

3, bolt taut band

Present embodiment mainly is made up of mouth mask cover 1, filter chamber 2 and bolt taut band 3, and wherein: mouth mask cover 1 comprises vapour barrier 11, sealing adsorption layer 12, interior contact lining 13 and nose clip support column 14.

Vapour barrier 11 is narrow or wide rectangle skins of being made by Polypropylence Sheet, plays the sealant of nose or nose and mouth and isolate from outer air.

Sealing adsorption layer 12 is internal layers of being made I shape by soft sponge, its straight section is bonded in the middle of the vapour barrier 11 (over against the nostril or nostril and mouth), play and attach dust in air, bacterium (microorganism), especially under exhalation hot water gas, absorption dust, bacterium is stronger, and upper and lower crosspiece is bonded in vapour barrier 11 upper and lower edges, seals.

Two nose clip support columns 14 are projection posts of being made by hard rubber, be connected on sealing adsorption layer 12 straight section both sides vapour barrier 11 inner faces, be supported in the nose clip (recess) of human nasal both sides, play 1 effect of the supporting mouth enclosure, make nose or do not overlapped 1 not compress, the people is felt comfortably cool by mouth mask with the nose lip.

In contact lining 13 be to be bonded in the sealing adsorption layer 12 upper and lower crosspieces 1 with cotton or multilayer gauze to make the skin tactility good.

Two filter chambers 2 are separately positioned on mouth mask and overlap 1 both sides, and it mainly comprises vapour barrier 21, adsorption column 22, prominent some hardboard 23, level and smooth hardboard 24 and inside and outside strong-

willed pipe

27,28.

Vapour barrier 21 is skins of being made by Polypropylence Sheet, makes the sealant of filter chamber 2 inside and isolate from outer air.

Adsorption column 22 is provided in a side of cylinder or the cone in the vapour barrier 21, is provided with the soft retaining cavernous body of curved passage 221 in it.

Prominent some hardboard 23 and level and smooth hardboard 24 are all made by rigid plastic sheet, be connected on curved passage 221 two sides in the adsorption column 22, and have the prominent some face of dashing forward a little with prominent some hardboard 23 contacts with the plane of level and smooth hardboard 24 more, after keeping adsorption column 22 compressive deformations, its curved passage 221 still keeps ventilation.

Inside and outside strong-

willed pipe

27,28, be plugged on adsorption column 22 inside and outside sidewalls respectively and be communicated with the respective end of bending passage 221, strong-willed pipe 28 enters curved passage 221 beyond making air, send into mouth, position, nostril by interior strong-willed pipe 27 again, make dust in air, microbial bacterial sticks to (on curved passage 221 walls, except that prominent some hardboard 23 and level and smooth hardboard 24) in the adsorption column 22.

In addition, also can place in the curved passage 221 in adsorption column or bonding sterilization layer 25, refrigerant spice layer 26 to entering the air disinfection sterilization (as: " SA " carbassus) in the adsorption column 22, makes the savory or mint flavored (needing preparation by the people) of people's inhaled air simultaneously.

Bolt taut band 3 two ends are connected to mouth mask and overlap on 1 inboard, with the resilient sleeve of its elastic cord at back of head or bolt tightly in back of head (genus prior art).
