Description
Technical field
The present invention relates to a kind of gauze mask, particularly a kind ofly can fit tightly people's face, ventilation effect is good, there is no the gauze mask of sensation of asphyxia.
Background technology
Existing gauze mask only has a function, can not, under specific environment, for a certain pollution, be on the defensive; Or existing gauze mask function is too many, can not under specific environment, effectively a certain single pollution be on the defensive, do not reach ideal effect.
Gauze mask is effectively secondary use after finishing using, and its protection effect does not reach requirement.
Transparent gauze mask, in use, can cause the inner fog that produces of gauze mask, impact talk effect because of the human body steam producing of giving vent to anger.
Transparent gauze mask, in use, because the empty filterability of taking a breath is good, causes air exchange slow, to user, has brought sensation of asphyxia.
Summary of the invention
Purpose of design: avoid the weak point in background technology, design and a kind ofly can fit tightly people's face, ventilation effect is good, there is no the gauze mask of sensation of asphyxia.
Design: in order to realize above-mentioned purpose of design, the present invention in design, a kind of gauze mask, comprise transparent cover, transparent cover edge is provided with two-layer outer, between two-layer outer, form detent, in detent, holding jacket is equipped with silica gel sheath, transparent cover is provided with intake region, intake region is coated with filter, intake region is provided with hollow hole and some valve openings of space, on filter, there is the barb that coordinates location with valve opening, the top, intake region both sides of described transparent cover respectively has an exhaling hole, on exhaling hole, sealing is provided with outlet valve, described outlet valve is just facing transparent cover outside, the outlet valve back side is towards transparent cover inner side, outlet valve front is provided with the grid of giving vent to anger, the outlet valve back side is the circular hole that radius is less than outlet valve outer ring radius, between outlet valve front and the back side, be provided with barrier film, barrier film is rounded, barrier film radius is greater than outlet valve back side circle hole radius.
A gauze mask, on described barrier film, part is fixed with outlet valve, and described barrier film top is divided into the part of 1/2nd to 1/4th of barrier film.
A gauze mask, described barrier film is close to circular hole.
A kind of gauze mask, give vent to anger region shape and filter form fit, inner hollow out is also mutually corresponding, and in the region of giving vent to anger, is provided with at least two valve openings, barb quantity on filter is consistent with valve opening quantity, and at least two barb hook directions of filter deviate from setting.
A gauze mask, the give vent to anger radian of area surfaces of filter and transparent cover is consistent, and filter and the transparent cover edges of regions of giving vent to anger is close to setting.
A gauze mask, transparent cover approach outer surface outer be each side provided with at least one frenulum hole.
A gauze mask, the frenulum hole that transparent cover approaches on the outer of outer surface is symmetrical between two, and the outer face at place, frenulum hole is trapezoidal projection.
A gauze mask, the open area border that transparent cover outer rim is enclosed is the middle part three-dimensional curve recessed to closed side, top edge and lower limb are invested and are projected as normal distribution curve shape on the horizontal plane while having worn.
A gauze mask, transparent cover closed area forward end is shunk, and front end has the platform that radian is less than 30 °, and the region of giving vent to anger is positioned in the lower wall while having worn.
The present invention compares with background technology, and the one, can be different according to environment, change filter, reach the object that gauze mask effect is different; The 2nd, the filter in gauze mask was because using filter effect of a specified duration to reduce, and the filter more renewing can use again, and effect improves; The 3rd, effectively avoid gauze mask inside when user speaks, to produce fog, affect communicative effect; The 4th, the design of the syndeton of valve opening and barb, had not only facilitated and had clamped but also convenient disassembly; The 5th, improved sealing and the practicality of gauze mask; The 6th, filter and gauze mask are easily separated, and easy cleaning and sterilizing can Reusability, saves material and environmental protection; The 7th, guarantee that the ventilation of gauze mask inside is quick.

The specific embodiment
Embodiment 1: with reference to accompanying drawing 1-3.A kind of gauze mask, comprise transparent cover 1, transparent cover 1 edge is provided with two-layer outer 4, 4 of two-layer outers form detent, in detent, holding jacket is equipped with silica gel sheath, transparent cover is provided with intake region, intake region is coated with filter 5, intake region is provided with hollow hole and some valve openings of space, on filter 5, there is the barb that coordinates location with valve opening, the top, intake region both sides of described transparent cover 1 respectively has an exhaling hole, on exhaling hole, sealing is provided with outlet valve 2, described outlet valve 2 is just facing transparent cover 1 outside, outlet valve 2 back sides are towards transparent cover 1 inner side, outlet valve 2 fronts are provided with the grid 3 of giving vent to anger, outlet valve 2 back sides are the circular hole 7 that radius is less than outlet valve 2 outer ring radiuses, between outlet valve 2 fronts and the back side, be provided with barrier film 6, barrier film 6 is rounded, barrier film 6 radiuses are greater than outlet valve 2 back side circular hole 7 radiuses.
A gauze mask, on described barrier film 6, part is fixing with outlet valve 2, and described barrier film 6 tops are divided into the part of 1/2nd to 1/4th of barrier film 6.
A gauze mask, described barrier film 6 is close to circular hole 7.
A kind of gauze mask, give vent to anger region shape and filter 5 form fit, inner hollow out is also mutually corresponding, and in the region of giving vent to anger, is provided with at least two valve openings, barb quantity on filter 5 is consistent with valve opening quantity, and at least two barb hook directions of filter 5 deviate from setting.
