Abstract
It the utility model is related to a kind of mouth mask of replaceable cartridge, including cover body and the banding ear-hang at connected cover body both ends, it is characterised in that：Filter core is removably fixed with the outside of cover body, the filter core is adapted with default air inlet on cover body, the filter core is pressed together on the air inlet of the cover body by fastener on the outside of cover body, the outer ring of the filter core is closely fitted with a circle silicone valve, the silicone valve is provided with blow vent in itself and the cover body place of overlapping, and the mouth mask has：When user wears mouth mask air-breathing, the silicone valve be close to the first state that blow vent, air enter at filter core, and when user wears mouth mask expiration, the second state that the silicone valve is discharged away from blow vent, air at blow vent.Filtration core is designed to that dismounting is fixed from outside by the mouth mask, changes convenient, safety and sanitation, and because all attachment structures are more convenient all in outside, mould production.
Description
Technical field
A kind of mouth mask is the utility model is related to, is specifically a kind of mouth mask of replaceable cartridge, belongs to personal protection skill
Art field.
Background technology
Mouth mask, it is particulate matter mainly to deter object, and specifically, mouth mask is by covering the mouth, nose and chin portion of people, shape
Into one and the space of face sealing, pollution air is forced by filtering by people's air-breathing.At present mouth mask on the market be typically all by
Layer of non-woven fabric and the ear-hang composition for being arranged at non-woven fabrics both ends, it is merely able to filter larger particle or dust, and it can not
Meet consumer demand.Also a kind of protective mask of main flow is that whole mouth mask is filtering material, and individual exhale is provided with mouth mask
Stomata, be that filter area is larger the advantages of the design, but it is this design be doomed mouth mask service life it is very short, and do not have
Cleaning or the possibility replaced.
Utility model content
Technical problem to be solved in the utility model is the shortcomings that overcoming prior art, there is provided a kind of filter effect is excellent
In existing filter face mask and the mouth mask of filter core can be changed.
In order to solve the above technical problems, the utility model provides a kind of mouth mask of replaceable cartridge, including cover body and solid
The even banding ear-hang at cover body both ends, cover body outside are removably fixed with filter core, and filter core is adapted with default air inlet on cover body,
Filter core is located at outside cover body detachably, exactly in order to ensure that user installation is easy to use, and for reducing production
Difficulty and cost；Filter core is pressed together on the air inlet of cover body by fastener on the outside of cover body, and the outer ring of filter core is closely fitted with one
Enclose silicone valve, valve block and filter core are set to one, and sealing property is more preferable, while reduces gas leakage and space hold, cover body its with
The silicone valve place of overlapping is provided with blow vent, and mouth mask has：When user wear mouth mask air-breathing when, silicone valve be close to blow vent,
The first state that air enters at filter core, and when user wear mouth mask exhale when, the silicone valve is away from blow vent, sky
The second state that gas is discharged at blow vent.As long as user is in use, filter core is fastened on to the correspondence position of cover body can just complete
Assembling, filter core can pull down to be kept separately when not in use avoid its Long Term Contact air from being contaminated, and the cover body for pulling down filter core can
With individually cleaning.
The technical scheme that the utility model further limits is：
Further, filter core spatially shape including stator and filter disc, the outer loop-shaped of the stator and cover body air inlet
Intraoral loop-shaped is adapted, and the filter disc level is pressed together in stator, and the stator is fastened on by fix bar and hasp
On cover body, the positioning hole being adapted with fix bar is provided with the pressing piece.
Further, air inlet is arranged at relative at user's mouth and nose.
Further, fix bar is symmetrically distributed on the cover body of air inlet both sides for two, plays fixed and positioning work
With the hasp is the primary and secondary hasp being distributed on stator and cover body.
The beneficial effects of the utility model are：Filtration core is designed to that dismounting is fixed from outside by the mouth mask, changes convenient, peace
Full health, and because all attachment structures are more convenient all in outside, mould production.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
In figure：Cover body 1, ear-hang 2, filter disc 3, fix bar 4, blow vent 5, hasp 6, silicone valve 7, stator 8.
Embodiment
Embodiment 1
The mouth mask for a kind of replaceable cartridge that the present embodiment provides, as shown in figure 1, including cover body 1 and connected cover body both ends
Banding ear-hang 2, the outside of cover body 1 is removably fixed with filter core, and filter core is adapted with default air inlet on cover body, and filter core passes through
Fastener is pressed together on the air inlet of cover body on the outside of cover body, and air inlet is arranged at relative at user's mouth and nose.The outer ring of filter core
A circle silicone valve 7 is closely fitted with, cover body 1 is provided with blow vent 5 in itself and the place of overlapping of silicone valve 7, and mouth mask has：When with
When mouth mask air-breathing is worn at family, silicone valve 7 be close to the first state that blow vent 5, air enter at filter core, and when user's pendant
Wear masks when exhaling, the second state discharged away from blow vent 5, air at blow vent 5 of silicone valve 7.
Filter core spatially shape including stator 8 and filter disc 3, cast in 8 outer loop-shaped of stator and the air inlet of cover body 1
Shape is adapted, and the level of filter disc 3 is pressed together in stator 8, and stator 8 is fastened on cover body 1 by fix bar 4 and hasp 6, fixed
The positioning hole being adapted with fix bar 4 is provided with piece 8.Fix bar 4 is on two cover bodies 1 for being symmetrically distributed in air inlet both sides,
Hasp 6 is the primary and secondary hasp being distributed on stator 8 and cover body 1.
In addition to the implementation, the utility model can also have other embodiment.It is all to use equivalent substitution or equivalent change
The technical scheme to be formed is changed, all falls within the protection domain of the requires of the utility model.
