Description
[technical field]
The utility model relates to a kind of mouth mask, espespecially a kind of windproof mouth mask with replaceable filtering element (cartridge) inner cover and air check valve, can while providing protection effect, high efficiency filter noxious air particulate, and gas permeability is good.
[background technology]
Since the industrial revolution, harmful aerosol particles in air is as sand and dust, fossil fuel, locomotive waste gas, industrial waste gas and photochemical fog or haze evil etc., nasal respiration of blurting out invades in human respiratory tract and alveolar, not only cause respiratory disease, as lung cancer, pulmonary emphysema, asthma, rhinitis, bronchitis etc., also along with harmful substance is transported in systemic circulation by blood, cause disease of cardiovascular system, hematological system, reproductive system pathology etc.
Once there is the severe air contamination accident that a large amount of aerosol particles of too much cause causes in history, as the serious haze evil of London on December 5 nineteen fifty-two to December 10, produce during haze evil and measure greatly bronchitis, Bronchopneumonia, cardiopathic sufferer, amount to 4, people more than 000 is dead, several weeks after haze evil, have 8 again, people more than 000, because of heart and lung diseases or the death of other chronic diseases, adds up to death toll to reach 12, more than 000 people; Mie Prefecture, Japan Yokkaichi between nineteen sixty to 1972, the extensive asthma disease-yokkachi asthma caused because of the sulfur oxide contamination air of enterprise's discharge, is one of Japan's four large nuisance diseases, caused nearly 1000 people collective to cause asthma at that time; Northeast China in 2013 centered by Harbin, the extensive haze that occurs in interior area of Jilin Province, Heilongjiang Province, Liaoning Province pollutes, cause airport to be forced to close because visibility is too low, more than 2000 school closure, Heilongjiang Province within the border many highways is forced to close; And according to statistics, Iranian Teheran has dead because of air pollution more than 5000 people every year.
Except taking petrochemical industry as the main air pollution harm caused, pollen floating in air, bacterium or virus, also can cause human body to produce irritated, or infected pandemic, as SARS (Severe Acute Respiratory Syndrome) or influenza etc.
Because aforementioned aerosol particles is mostly very small, not general operation mouth mask or active carbon mask can intercept, therefore the pollution sources such as such as haze, pollen, virus, bacterium will be taken precautions against, must based on N95 protective mask, N95 mouth mask can stop 0.3 micron particles of more than 95%, but more airtight, be not suitable for wearing for a long time, and cannot reuse.
[utility model content]
The windproof mouth mask of high efficiency filter that the utility model provides a kind of gas permeability good, replaceable, it comprises: an outer cover, has multiple perforate; At least two neckstrap, have a connection piece, and at least two neckstrap are connected with outer cover; One inner cover, overlapped by multiple film and form, and inner cover has multiple perforate, inner cover and outer cover mutually overlap and arrange; One non-return valve, non-return valve is cover-lifting type; And a press strip, be arranged at outer cover, wherein non-return valve is by multiple perforate, outer cover and inner cover is connected side by side to form mouth mask.
In the middle of, outer cover can the material of similar diving cloth be made, and has protection effect, also can be cleaned and reuse, and its made of soft has elasticity, can with skin attachement, be applicable to the shape of face of coated various different radian.And the space at bridge of the nose place, by the press strip being arranged at outer cover, bridge of the nose space can be covered, improve the adaptation of mouth mask and face.
At least two neckstrap, for around neck, and with the connector on it, can make at least two neckstrap around to user's neck rear place, and that fixes whole mouth mask with connector wears position.
Inner cover, overlapped by multiple film and form, wherein a film can comprise with polytetrafluoroethylene (PTFE) (polytetrafluoroethylene; PTFE) film that material is made formed.This film material effectively can filter out 0.3 micron particles of 99.9%, compared to General N 95 mouth mask, better for the effect of filtering various noxious air particulate.
The setting of non-return valve can make the expiration of mouth mask wearer more smooth and easy, and the gas of breathing out can directly be discharged through non-return valve, can not stay in mouth mask, cause the sensation of humid; And when air-breathing, gas cannot enter by Self-check valve, only be inhaled into by the outer cover of mouth mask and inner cover, therefore the gas sucked has to pass through the filtration layer by layer of plural layers, just human body can be entered, compare general mouth mask, this creation can provide a kind of more comfortable ventilating and effectively can block the mouth mask of pollutant when making to wear.
