Description
Technical field
The utility model relates to mask technical field more particularly to a kind of sealing masks for facilitating expiration.
Background technique
Mask is a kind of healthy prevention apparatus, includes germ, virus, suspension for reducing or preventing deleterious particle in air
Particle, pernicious gas etc. suck in lung, ensure that wearer sucks pure air to a certain extent, are widely used in working
Protection, healthcare field.It points out in the related technology, it, can will be in mask since the bridge of the nose of user is higher when user wears common mask
It is jacked up at the heart, so that the mask part opposite with bridge of the nose two sides is not bonded, generates huge gap.Thus it is possible, on the one hand, not filtered
Air can by this gap by user breathe to nasal cavity and oral cavity, cut down the filter effect of mask, on the other hand, user
On the eyeglass for the glasses that the moisture of exhalation can flow to bridge of the nose upper support by this gap, the problem of causing eyeglass to haze, shadow
Ring the visual field of user.In the high environment of certain pollution levels, the mask for wearing effective protection has become necessary protection tool.Mesh
Preceding mask is divided into air filtering type mask and Gas feeding mask, and be difficult can be very by mask and face for air filtering type mask
Good fitting, effectively cannot be isolated in outside for pernicious gas, in air-breathing, noxious air be easy the gap being never bonded into
Enter, to weaken, reduce the effect of mask.Meanwhile the face contour of people is had nothing in common with each other, so the mask of same size is difficult to paste
The face of the face of conjunction different people, mask and people, which are bonded untight words wearer, still can breathe unpurified air.
The sealing effect of mask is poor at present, cannot fit closely the periphery of mask and user's skin of face, and right
For some users with eyes, steam can be flowed out by the periphery of mask and the gap of face, so that condensation vapor exists
Fog is formed on spectacle lens, the situation for causing sight unclear occurs, to interfere the normal activity of wearer.
Utility model content
The purpose of this utility model is to provide a kind of sealing masks for facilitating expiration, have good seal performance, prevent water
Vapour condenses advantage more convenient with outlet on the ophthalmic lens, and the sealing effect for solving current mask is poor, cannot be by mask
Periphery fitted closely with user's skin of face, and for some users with eyes, steam can pass through mask
The gap of periphery and face is flowed out, so that condensation vapor forms fog on the ophthalmic lens, the situation for causing sight unclear occurs, from
And the problem of interfering the normal activity of wearer.
According to a kind of sealing mask for facilitating expiration of the utility model embodiment, including mask main body, mask main body is left
Right two sides are equipped with quick fixing belt, it is characterised in that further include silica gel fitting cover, several one-way ventilating components, in mask main body
Several perforative through-holes are provided with, each one-way ventilating component, which extends through, to be set in through-hole, indent on rear side of the mask main body
Structure, edge are connected with silica gel fitting cover for one week, and the one-way ventilating component includes valve body, spool, end cap, and valve body is solid
It is scheduled on mask main body, valve body one end is equipped with end cap, and the other end is equipped with ventilating cover, is equipped with guide part in the middle part of the end cap lower end,
Guide part lower end is slidably connected by outer tube and spool, and back-moving spring is equipped on the outside of spool upper end.
Further, the silica gel fitting cover is connect by flexible joint with mask main body rear lateral edge.
Further, the front side of the flexible joint is sewed up or be bonded for one week with mask main body rear lateral edge；Flexibility is even
The rear side one week of socket part and silica gel, which are bonded cover front side and connect for one week, to be sewed up or be bonded.
Further, the cross section of the flexible joint is accordion-like.
Further, the silica gel fitting cover is flexible flake or its edge is flexible flake.
Further, the one-way ventilating component is the downward Unidirectional air outlet pipe in direction.
Further, the mask main body top is equipped with the sheet metal for sizing.
The utility model has the beneficial effect that compared with prior art
1. the sealing element of the flexible joint being added, silica gel fitting cover composition may be implemented to fit closely with face, add
The quick fixing belt entered can keep fitting closely, and the flexible connection cross section being added is accordion-like, so that wearing more
Comfortably, make silica gel fitting cover with face be bonded it is even closer, prevent gas be bonded from face with silica gel cover between gap into
Out, at the same the flexible joint of accordion-like also can be bigger retractility, in order to adapt to different shapes of face；The one-way ventilating of addition
The high pressure gas of exhalation quickly can be oriented discharge by pipe, realize reduction of blood pressure in high-speed, be prevented because pressure is excessive so that gas is from mouth
The periphery of cover and the gap of face are flowed out, and the lens atomization of wearing glasses can be effectively prevented.
