Description
Technical field
The utility model relates to Wearable air cleaning facility, is specifically related to a kind of bionical breathing mask.
Background technology
Human lung is the main position of gas exchange, during gas exchange, mainly by lung's respiratory membrane, is undertaken, and lung's respiratory membrane has very high permeability, therefore gas exchange is very rapid.But when the suspended particulate substance diameter in human body air amount is greater than 2.5 microns, airborne suspended particulate substance can stop up lung be used for exchange respiratory membrane, can affect in the course of time human lung's gas exchange work energy, affect people's eupnea.
Along with the development of human society, industrial gas emission, the factors such as all kinds of vehicles exhaust emissions cause air severe contamination.Particularly in recent years, due to the multiple haze weather of China that ecological deterioration causes, easily bring out respiratory tract, the disease such as cardiovascular, gently can cause outside the nasal cavity diseases such as rhinitis, heavy can cause lung sclerosis, even also likely cause lung cancer, had a strong impact on people's health.
To this, people expect dirty air to filter, and make the pure of air change.In prior art, the general design of using similar gas mask of purifier for Wearable breathing gas, use sealing face shield that mouth and nose are isolated from the outside, on face shield, be provided with filter, the negative pressure of the facepiece interior producing while utilizing people air-breathing, makes extraneous air enter face shield by filter and realizes purification function.Also have by increase purifier in face shield and with conduit, the air after purifying is transported in face shield, attempt to supplement the deficiency of air in face shield.
Yet there is following defect in this class face shield:
1. filtering is the passive air inlet by human body respiration effect, and owing to filtering, air inlet area is little, and the thick postemphasis breathing burden of wearing of filtering layer can allow user feel to breathe with difficulty, and comfortableness is poor.
2. because mouth and nose are all sealed, basic activity is influenced to cause that user speaks etc.
3. put on rear very not attractive in appearancely, user wears to go out and can show slightly awkward.
4. the waste gas of wearing rear characteristics of contaminated respiratory droplets in time discharger is outside, and while causing circulation air-breathing, waste gas and fresh air mix.
Common mouth mask or face shield can not with human nose surface gluing, sealing completely, cause completely cutting off waste gas completely.
The technical term that this patent is relevant is explained as follows:
HEPA filter paper: High efficiency particulate air Filter, the abbreviation of efficient air purifier, is accessible dry type filter, is made by lamination shape borosilicate microfibre.
Utility model content
For the problems referred to above, the utility model aims to provide that a kind of filtration air inlet area is large, inspiratory resistance is little, filters good seal performance, can completely cut off waste gas completely, and the impregnable bionical breathing mask of basic activity such as speak.
The technical scheme that the utility model is dealt with problems is: a kind of bionical breathing mask, comprise the elementary mouth mask with ear band, on elementary mouth mask, be equipped with breath assembly, described breath assembly comprises positive fixed support and a pair of breath skeleton with skeleton hole, on breath skeleton, be coated with respectively the hollow cryptomere filter bag that HEPA filter paper is made, a pair of breath skeleton that is coated with hollow cryptomere filter bag is assemblied in respectively in support bracket fastened skeleton hole; Meanwhile, support bracket fastened bottom is provided with check valve installing hole, in this check valve installing hole, check valve is installed; Support bracket fastened outer surface covers air inlet guard is installed, described in be coated with hollow cryptomere filter bag a pair of breath skeleton between fixed support and air inlet guard;
Described fixed support dorsal part is connected with the sealing nose cup that can cover nose completely, sealing nose cup comprises the soft silica gel part contacting with nose, this soft silica gel part back side is fixedly connected with the hard plastic glue part identical with soft silica gel part size, and hard plastic glue part is connected with fixed support.
Further improvement as such scheme, on described breath skeleton, be coated with respectively the multilayer hollow cryptomere filter bag being formed by stacking by a plurality of individual layer hollow cryptomere filter bags, filter area during with increase air inlet, the increase of filter area further makes inspiratory resistance less.
Preferably, described check valve is silica gel check valve sheet, and seal better and environmental protection more.
In technique scheme, described air inlet guard covers the check valve of fixed support bottom, has replaced the function of valve gap, to check valve protection and spacing.
In technique scheme, described elementary mouth mask is provided with clasp, and the air inlet guard in breath assembly is provided with back-off, and the assembling by clasp and back-off is connected breath assembly with elementary mouth mask.
In technique scheme, described sealing nose cup and fixed support interference fit, form seal form completely.
Further, between described air inlet guard and hard plastic glue part, breath skeleton and the fixed support of sealing nose cup, be and removably connect, convenient for dismounting and washing replacing.
The beneficial effects of the utility model are:
1. owing to having designed hollow cryptomere filter bag, filter area when air-breathing is increased, thereby respiratory resistance is reduced, breathe burden and reduce, can not make people feel to feel suffocated.
2. the soft silica gel part that sealing contact with nose on the nose cup nostril of can perfectly fitting, makes it to isolate completely with outside contamination source.
3. the design of check valve can be got rid of the waste gas of breathing out in time, can not repeat to suck waste gas.
4. owing to being dismountable connection between each parts of breathing mask of the present utility model, unpick and wash change very convenient.
5. when breathing mask of the present utility model uses, breath assembly only covers nose, at regular intervals between elementary mouth mask and face, does not seal mouth, can not impact the basic activity such as speak.
Hollow cryptomere filter bag in the bionical breathing mask of the utility model, just seem human lung's respiratory membrane, under initiatively breathing, human body effectively in filtered air, is greater than the suspended particulate substance of 2.5 microns, the partial function that has replaced lung, for human lung's breathing gas carries out pre-filtering, prevent that particle from stopping up the respiratory membrane in pulmonary alveoli.
