Description
Technical field
The present invention relates to a kind of mouth mask, particularly relate to a kind of by horizontal for one-way exhaust valve and be designed with thin tail pipe after one-way exhaust valve, solve when people feel suffocated when exhalation air and suck air and make outside foul atmosphere blow back into again the horizontal valve of thin tail pipe of problem within one-way exhaust valve without returning dirty mouth mask because one-way exhaust valve is closed comparatively late.
Background technology
Report according to authoritative institution: current domestic pneumoconiosis cumulative cases and suspicious pneumoconiosis (0+) case have 6,000,000 at least in China.I also believes that this numeral has many nothings few, because my " pressure-guiding bedpan " patent is implemented in Chaozhou, Guangdong Heng Jie bathroom factory, has undergone 4 years, has even worried unconsciously just likely " acceptance of the bid ".
Pneumoconiosis is the most serious occupational disease of harm China workers ' health.Especially attach most importance to coal, ceramic industry system, annual pneumoconiosis reaches more than 80 hundred million yuan to the direct economic loss that country causes, and also causes bad political fallout at home and abroad simultaneously.In the face of numerous existing patient, enterprise particularly society is studded with many Pneumoconiosis Patients departed from employing unit especially, and become the disadvantaged group being badly in need of succouring, these have developed into more and more serious social concern all.I to be fair, present most private enterprise is all at a loss what to do for dust-proof problem: the custom of workman reverse do not come, too high, the direct discharge policy of the cost that purifies air do not allow again.So dust-proof problem is still just cried out oral, actual can only see the warm tip that the top of a wall will wear masks.If enterprise too publicizes dust, pernicious gas to human injury's degree, near says recruitment difficulty, and far point says the trouble of being also afraid of to look for enterprise the older moon for a long time afterwards.I is really that the health of 300,000,000 peasant brothers is weighed down with anxiety.
This just has two problems to put to require study in face of us: one is why not employee likes wearing masks, and two is that what problem is the serviceability aspect of mouth mask mainly have.
The mouth mask that present people use mainly is divided into without one way stop peturn valve and has the large class of one way stop peturn valve two.General gauze, the Simple mask of papery are without one way stop peturn valve, and the air of suction and exhalation is all through same pore area; The existing one way stop peturn valve of high-grade mouth mask, also has the filter of air filtration excellent effect, and suction and the air of breathing out are taken their own roads.
According to precision test, when people suck and breathe out, blast is greater than 98 handkerchiefs, just has the sense of discomfort, just feels more directly to feel suffocated greatlyr.For the Simple mask without one way stop peturn valve, people is felt suffocated to understand very well, because it is too simple, air inlet and exhaust, all through filter screen, do not have unimpeded exhaust apparatus; And why workman is also unwilling to wear the high-grade mouth mask of one-way exhaust valve? I conscientiously studied profoundness wherein, was because there is the mouth mask of one-way exhaust valve all to have following several respects problem.
One is that the setting direction of one-way exhaust valve is unreasonable.If we say that the face of people in daily life is perpendicular to the ground time most, so, it is alternatively perpendicular to the ground for being worn over that face muzzles.In the high-grade mouth mask that we use now, all one-way exhaust valves are all be close to generation along the position, middle and lower part of mouth mask cambered surface, and that is, one-way exhaust valve carries out work under always erecting the state of putting.Elastic membrane under perpendicular state of putting easily is out of shape, and causes poorly sealed; Secondly, elastic membrane total amount has certain weight, does not utilize its self intrinsic weight to close.
Two is that the open and close of one-way exhaust valve are dumb.Now commercially the elastic membrane of one-way exhaust valve has certain intrinsic tension force to be implemented close and have certain thickness to prevent self-deformation by seal, and this tension force and thickness are exactly directly cause the basic reason that open and close are dumb and feel suffocated.Because be almost want accessible by air-flow in the blast standard of 98 handkerchiefs, the stop of larger intrinsic tension force just can not be had.And if the perpendicular drain tap put does not have certain intrinsic tension force just can not to close in time, so its open and close are dumb is exactly the reason of directly feeling suffocated.
Three be one-way exhaust valve when can bring contaminated air into.All one-way exhaust valves are formed by elastic membrane and seal, and open and close by air-flow to action after elastic membrane force, the seal force of elastic membrane and seal all relies on the strength of air-flow.We know, have the generation of air-flow strength that gas just must be had to pass through.Be exactly and the air polluted outside one-way exhaust valve, so, always have a small amount of contaminated air to flow into one-way exhaust valve door.
Whether the reason that workman is unwilling to wear masks have found, but have practical ways to overcome above-mentioned drawback in existing mouth mask, allow workman can conscious mouth mask of wearing to safeguard the health of oneself? so we have done following discussion.
Summary of the invention
The present invention relates to a kind of mouth mask, particularly relate to a kind of by horizontal for one-way exhaust valve and be designed with thin tail pipe after one-way exhaust valve, solve when people feel suffocated when exhalation air and suck air and make outside foul atmosphere blow back into again the horizontal valve of thin tail pipe of problem within one-way exhaust valve without returning dirty mouth mask because one-way exhaust valve is closed comparatively late.
Above-mentioned technical problem of the present invention solves without returning dirty mouth mask by providing a kind of horizontal valve of thin tail pipe of following structure, it comprises: mask main body, elastic membrane, thin tail pipe, check valve seal, exhaust outlet, filtered air inlet, high pressure admission mouth, it is characterized in that: described check valve seal is horizontally placed on mask main body, its alignment error controls facing upward or downward between each 45 degree; Described elastic membrane is positioned at the top of check valve seal; Have one section of thin tail pipe between described check valve seal and exhaust outlet, the cross-sectional area of thin tail pipe is less than the area of elastic membrane.
The horizontal valve of the thin tail pipe of the present invention has the following advantages without returning dirty mouth mask tool compared with the existing mouth mask in market:
1, the design of horizontal valve, can prevent the distortion of elastic membrane and utilize elastic membrane own wt to implement sealing.The drain tap of present all mouth masks is all be attached to before mouth and nose, and that is drain tap is perpendicular puts, and its elastic membrane is also perpendicular putting.Perpendicular elastic membrane of putting has two shortcomings, and one is that elastic membrane is easily out of shape, and causes and is not closed completely, and makes contaminated air seal in mouth mask; Two is do not utilize the gravity of elastic membrane self to help to close drain tap as early as possible, and valve closing is relatively slow.Check valve seal is flat on mask main body without returning dirty mouth mask by the horizontal valve of the thin tail pipe of the present invention, most probability is that the open and flat formula of elastic membrane is attached to seal and relies on the gravity of self just can tightly be closed by check valve seal, so, can intrinsic for elastic membrane Tension design be obtained very little during design, and easily keep intrinsic elasticity, achieve and open flexibly, close timely and long-lived object, from the problem solving people to a great extent and feel to feel suffocated.Certainly, what this horizontal valve neither be absolute is vertical with mask main body by valve, faces upward or downward that respectively to depart from 45 degree be also the example belonging to rights protection of the present invention.
2, the design of thin tail pipe, makes dirty air away from elastic membrane, can prevent the contaminated air string of outside to answer back cover.Being exactly face atmospheric environment directly outside present all mouth mask drain taps, returning when elastic membrane is closed there being air-flow, the air returned is exactly dirty outside air, the air of these dirts more or less be directly drawn into the lung of people.The horizontal valve of the thin tail pipe of the present invention is designed with elongated thin tail pipe without returning dirty mouth mask after elastic membrane, and the cross-sectional area of thin tail pipe is less than the area of elastic membrane.Like this, people will be blown away outside air in thin tail pipe when breath; When people suck air, there will be negative pressure in mouth mask, the air of backflow makes elastic membrane seal, and at this moment, the return air through elastic membrane is not just extraneous foul atmosphere, but the air little by little just oneself spued, so, serve without returning dirty effect.
3, product with compact structure, wide accommodation.The drain tap of existing mouth mask is all smaller, if reason to be elastic membrane area large easy distortion.Therefore, existing mouth mask can not be used for fresh air source.Otherwise, the air pressure produced in mouth mask people can be made to feel gas blocks up.The horizontal valve of the thin tail pipe of the present invention, without returning dirty mouth mask because drain tap is horizontal, also can not be out of shape and affect cut out in time sufficiently large for the area of elastic membrane.If its check valve seal, elastic membrane and thin this three part of tail pipe are made an entirety, it is not only applicable to being arranged on the high-grade mouth mask of fixed frame, is also applicable to being arranged on general gauze, paper face mask.
Accompanying drawing explanation
Below with reference to accompanying drawings embodiments of the present invention are described.
Fig. 1 is that the horizontal valve of the thin tail pipe of the present invention is without the cross-sectional view of returning dirty mouth mask.
Detailed description of the invention
Fig. 1 shows the horizontal valve of the thin tail pipe of the present invention without the detailed description of the invention of returning dirty mouth mask.In diagram, mask main body 1 is vertical state.Check valve seal 4 is the middle and lower parts being horizontally placed on mask main body 1, and when actual installation, check valve seal 4 and mask main body 1 alignment error control facing upward or downward between each 45 degree.Elastic membrane 2 is close on check valve seal 4.The upper first elastic membrane 2 of thin tail pipe 3 covers reality, and following is exhaust outlet 5.The cross-sectional area of thin tail pipe 3 is always less than the area of elastic membrane 2, but under the prerequisite not causing the gas of backflow to seal within check valve seal 4, thin tail pipe 3 cross-sectional area should do greatly as far as possible.Installation quantity, the particular location of filtered air inlet 6 and high pressure admission mouth 7 are determined according to the profile of mask main body 1.
When people breathe out air, the gas of lung or also will add that the gas that high pressure admission mouth 7 provides can make to be in barotropic state in mask main body 1, elastic membrane 2 is blown open, and gas is discharged through thin tail pipe 3, exhaust outlet 5.
When people suck air, the gas of more than 200 milliliter within about 1 second, will be sucked, when high pressure admission mouth 7 has been installed exactly, in mask main body 1, also will form negative pressure.Mask main body 1 is interior is time moment from being just pressed onto negative pressure, the air-flow that elastic membrane 2 sensitive again can not stop back string at once scurries into mask main body 1, and the air at this moment scurried into into is exactly the air just breathed out in elastic membrane 2 side, so stopped the possibility that external contaminant air scurries into people lung.
If its check valve seal, elastic membrane and thin this three part of tail pipe are made an entirety, it is not only applicable to being arranged on the high-grade mouth mask of fixed frame, is also applicable to being arranged on general gauze, paper face mask.
In the specific implementation, according to the tolerance situation that high pressure admission mouth 7 provides, the method that we suitably can increase check valve seal 4 regulates stream pressure in mask main body 1.
Certainly, the horizontal valve of the thin tail pipe of the present invention can also have multiple conversion and remodeling without returning dirty mouth mask, is not limited to the concrete structure of above-mentioned embodiment, as the multiple constituted mode of check valve seal and elastic membrane, all changes etc. of thin tail pipe geometry.In a word, the horizontal valve of the thin tail pipe of the present invention also should comprise those apparent exchanges to those skilled in the art without the protection domain returning dirty mouth mask, substitutes and change shape.
