Abstract

The breathing mask has its respiratory channel expanded to overall mask and thus has fluent respiration. It has sealed contact with sides of nose and faces to ensure safe respiration. Its inspiring and expiring channels may be separated, the damped expiring part may be replaced alone, and monoway expiring function may be also provided. The present invention can reach powerful protection effect.

Description

The permeability type mouth mask

Technical field

The invention belongs to the hygiene medical treatment apparatus

Background technology

Cotton cloth respirator before this, generally all make with rectangle multilayer gauze, there is many shortcomings, particularly put on behind the mouth mask because have only nostril and mouth, so little effective area is local to be breathed, people's aqueous vapor is just got this position of mouth mask wet quickly, gauze is splashed and is risen once mixing up cotton fiber, just stop the originally very little mouth and the respiration channel in nostril quickly, so feel very unhappy, and hole often arranged, make air directly enter respiratory tract from these both sides in wing of nose both sides, need add that eyeshade pushes down wing of nose both sides, just can play effect, because unhappy, the somebody simply encases oral area with mouth mask and exposes the nostril, both all make cotton cloth respirator become a kind of form, very science not.

Summary of the invention

The present invention is intended to solve when wearing masks; can feel to breathe smooth and easy; unconsciously unhappy; simultaneously it has and can make wing of nose both sides and touch the position sealing with face; can directly not enter air; and can be by the different product requirement; accomplish and breathe the shunting; and can guarantee that the air-breathing position of large tracts of land is dry all the time, the exhalation position can be changed lastblock multilayer small gauze at any time, also unidirectional degassing function can be arranged when special requirement simultaneously; can use for a long time; still can keep breathing smooth and easy, make cotton cloth respirator move towards scientific and reasonable, effectively play a protective role from archetype.

Permeability type mouth mask of the present invention, it has a projection to be the plastic cement skeleton of half red date shape, another side has the shape that matches with facial nose, and the soft limit of moulding that can cross on it cooperates nearly with face, above the protruding skeleton, wrap the multilayer gauze and or breathe effective area and expand whole mouth mask all sites quickly to, and can make by product requirement and breathe the shunting turnover, simultaneously also can be by dress exhalation one-way cock, make wear masks safer, breathe smooth and easy, unconsciously unhappy.

The permeability type mouth mask that above function has been arranged can make mouth mask breathe effective area and expand whole mouth mask area to, makes breathing smooth and easy not unhappy, whole mouth mask and facial fine tight the contact, prevent that effectively germ from entering, and can make by the difference requirement and breathe and the shunting mouth mask, make mouth mask suck position drying all the time, and unidirectional exhalation valve can be installed on demand, in the needs occasion, the long-time use still keeps the mouth mask drying, breathe smooth and easyly, make mouth mask have more science.

Specific implementation method

Be described below with reference to accompanying drawing in order to understand the present invention:

It has skeleton partly A and two main partly formations of surrounding layer B with reference to accompanying drawing 1,2 permeability type mouth masks.Skeleton is by netted composition the like half red date shape, constitute by a plurality of circular arcs with facial contact left part position, with reference to Fig. 3, middle upper portion is " V " word spill (6), match with nose, with reference to Fig. 1,2 these skeletons (2) match with face, the sealing ring of forming by a circle foamed material around the left part (3), encase gummed and skeleton (2) oral area joint all around by gauze, formation seals face, multilayer gauze (4) encases skeleton (2) outside, cingulum (1) will be fixed in mouth mask both sides up and down, with reference to Fig. 4,5 embodiment 1 bottoms in mouth mask, there is a bevel to be buckled in mouthful top, arc is breathed shunting utmost point interlayer (11), and this breathes shunting utmost point interlayer, a left part and a mouthful contact position, top, one circle sealing foam cushion rubber (7) is arranged, constitute the exhalation passage, there is the gauze layer that can often change (10) at expiratory port place, bottom, by cingulum (9) and fixedly play the part of (8) exhalation gauze layer (10) is fixed in the mouth mask bottom, with reference to Fig. 6 embodiment 2, exhalation channel C bottom, be that gauze layer (10) is located, the exhalation check valve that changed the outfit, this valve is by valve seat (13), skeleton (2) gummed in top and the exhalation channel C, there is expiratory port D the middle and upper part, and the middle and upper part has outlet holder (12) valve mounting glue (14) to be fixed on the sliding seat (16), sliding seat upwards can be promoted by spring (15), can close holder (12) outlet, spring is pressed metal plate (17), can move up and down by adjustment screw (18), reaches the sealing of levelling mounting glue (14) and holder (12) lower ports.

Use mouth mask of the present invention; can make mouth mask effectively breathe area; from having only mouth and two positions, nostril; expand whole mouth mask area to quickly; make breathing smooth and easy, do not feel unhappy, tolerance increases; have simultaneously and dilator naris and facial close fit foam cushion rubber; make bacterium can not enter mouth mask, make protection safer, and can make as required and breathe the shunting mouth mask; drying when the protection mouth mask is worn for a long time; make air-breathing smooth and easy exhalation gauze interchangeable at any time, can use this mouth mask by the dress one-way cock simultaneously; air-breathingly suck from the nostril; gas is pushed mounting glue downwards open by the exhalation road junction during exhalation, gives vent to anger to outlet D arrow two directions, when exhalation stops; because bourdon tube (15) effect; expiratory port is in time closed, draw into the one-way gas flow passage of only export but no import, can special procure continuous the use a few hours under the requirement condition; he can keep mouth mask to breathe good performance smoothly, and it is a cotton cloth respirator update science product.
