Description
Technical field
This utility model relates to consumer goods industries, is specially a kind of haze mask.
Background technology
Haze weather is a kind of atmospheric pollution state, haze is the general statement to suspended particulate substance content overproofs various in air, the especially PM2.5(equivalent aerodynamic diameter particulate matter less than or equal to 2.5 microns) it is considered as " arch-criminal " causing haze weather.Along with the deterioration of air quality, increasing occurs in thick weather phenomenon, and harm increases the weight of.The many areas of China are incorporated to mist together as diastrous weather early-warning and predicting thick weather phenomenon.
Kind more than 20 is reached containing various harmful fine graineds, noxious substance inside haze composition, include acid, alkali, salt, amine, phenol etc., and dust, pollen, acarid, influenza virus, tubercule bacillus, streptococcus pneumoniae etc., its content is tens times of normal atmospheric water droplet.Owing to the floating particle thing diameter of granular tiny in haze is typically below 0.01 micron, it directly can enter bronchus, even pulmonary by respiratory system.So, haze is to the respiratory system that human influence's maximum is exactly people, and the disease caused is concentrated mainly in the sick kind such as respiratory tract disease, cerebrovascular disease, nasal cavity inflammation.Meanwhile, during haze weather, air pressure reduction, Inhalable Particulate abruptly increase, air flow property are poor, and noxious bacteria and virus, to slowing of around spreading, cause virus concentration in air to increase, and the risk of pathophoresis is the highest.
For ordinarily resident, the means of the most direct pre-haze are to wear masks, common mask can not meet the travel requirement of people under haze weather, mask in the market is mostly Double-layer mask, owing to its safety and sanitation coefficient is the highest, it is served only for daily dust-proof, PM2.5 is not almost had protection effect；Although dust-proof effect preferable active carbon mask gas defence effect is pretty good, but shortcoming is that dust-proof effect is general, and carbon granule also can be inhaled into health, causes discomfort；By more three layers of mask being widely used in health care occasion and other public arenas, it is the most general to the protection effect of PM2.5.In order to solve above-mentioned technical problem, market also occurring in that PM2.5 anti-dust respirator, its key point solving technical problem is, add the superfine fibre filter course of one layer of absorbable PM2.5, although PM2.5 being served certain protection effect, but mask being when respiratory gas, is easily deformed, it is affixed on the face, causing hypopnea, major part mask there is problems simultaneously: existing defects in overall structure, inconvenient during storage, many times roll into a mass by kneading and be placed in pocket, unhygienic；Filter element, with mask integral structure, is difficult to cleaned and changed, and disposable breathing mask causes the waste to resource；The mask of part replaceable cartridge, its filter element fills in cover body by the opening on both sides, because both sides wide in the middle of general mask are narrow, inconvenient operation.
Summary of the invention
For solving the technical problem of above-mentioned existence, this utility model provides a kind of reasonable in design, filter element replacing facilitates, dresses, receives and keeps and put haze mask easily.
For reaching above-mentioned purpose, this utility model be the technical scheme is that
A kind of haze mask, it includes that cover body, filter element and cover body two ends are for the elastic frenulum being affiliated on ear, inside cover body, both sides end is provided with opening towards the sealing in the middle of cover body, filter element profile is similar to cover body, ratio is less than cover body, filter element both sides end can be plugged in cover body sealing, and sealed is pressed on cover body, and cover body avris is provided with expiratory one-way valve.
Further, filter element side is provided with breach, and breach size and position are consistent with check valve, and indentation, there is fixedly installed an internal ring, and internal ring can be fixed together with check valve inner edge.
Further, cover body includes left and right cover body, left and right cover body is welded together by hot pressing, a vertical cover body center line is formed in the middle part of whole cover body, center line be outer arcuate or three sections linear, left and right cover body along center line fold after in plane, when cover body launches, it is hood-like that mask is the interior solid buckled, and filter element is consistent with cover body external shape.
Described sealing is adhesion-proof cloth material, is close to inside cover body, and the three-dimensional edge of sealing is fixed together with cover body, only stays the vertical openings in the middle part of cover body.
The nearly nose of described cover body is built-in with plasticity nose clip, uses aluminum strip.
Described check valve is circular valve, valve is outside equipped with the outer housing of a circumferential openings, the closure plate of a circle it is provided with in outer housing, closure plate center is fixing with valve to be connected, and closure plate outer ring contacts connection with valve edge, during expiration, closure plate is blown afloat generation deformation, air-flow is breathed out by closure plate, and during air-breathing, closure plate shuts sealed valve；Check valve can be dismantled from cover body.
Described frenulum limit end at cover body limit end, frenulum is provided with bayonet unit by hot-melt adhesive paste, and bayonet unit is band or gantry folder with two perforation, and its effect is the length adjusting frenulum, wears crowd with adapt to all ages and classes level.
Described cover body is from outside to inside, including first filter layer, coarse filtration dust solution layer, antiseized layer of cloth, first filter layer is the bed of cloth that sindon layer i.e. presents mask outward appearance, and this layer uses chemical fabric material, coarse filtration dust solution layer is polypropylene superfine fiber filtering surface layer, and cover body is recycling capable of washing.
The beneficial effects of the utility model are:
It is furnished with easily detachable expiratory one-way valve, makes breathing more smooth and easy, comfortable, glasses will not produce fog, do not affect sight line；
Mask built-in plasticity nose clip, toughness height folding is constantly；
Chemical fabric material, is difficult to foldover, easy to clean；
Overall employing sweat soldering technique, especially mask center line hot weld, wire body is curved or three sections of line styles, rear solid type opened by mask, and whole mask support effect is good, upper and lower side good airproof performance, and the end of a thread free of pinholes, the also hot weld of the rope belt end on mask both sides, at mask edge, does not haves long-term stretching and wears, and the problem causing mask edge to crack occurs；
Filter element is corresponding with mask cover body shape, FOLD AND PACK, saves space, and after expansion, third dimension is strong, is not susceptible to deformation；Filter element inserts mask both ends open by even limit end and is fixed, and does not need to run through in the middle part of face shield and fills in, easy to operate；
Filtering layer by layer, cover body layer tentatively filters, and capable of washing reuses, and filter element layer depth filters, and can change easily, easy to operate.
Also being provided with breach on filter element, indentation, there is fixed with internal ring, can be fixed together with check valve inner edge, the most fixing filter element and the connection of cover body, prevents filter element from producing deformation because of respiratory air flow impact, causes and wear discomfort.
