Description

Anti-haze portable power respirator

Technical field

The utility model belongs to a kind of protective respirator, especially belongs to a kind of anti-haze portable power respirator.

Background technology

As everyone knows, the air pollution of China is very serious at present, and the health problem of respiratory tract is also on the rise.PM2.5 refers to that in atmosphere, diameter is less than or equal to the particle of 2.5 microns, is called and can enters lung particle.

Poisonous particle in haze sky air---PM2.5 particle hinders normal blood circulation, cause cardiovascular disease, hypertension, coronary heart disease, cerebral hemorrhage, can bring out angina pectoris, miocardial infarction, heart failure etc., make chronic bronchitis occur cor pulmonale etc.Along with the deterioration of air quality, what thick weather occurred increases, and harm effect increases the weight of, and makes chronic disease aggravation, makes respiratory system and cardiac system disease progression, changes PFT and structure, affects fecundity, changes the immune structure of human body etc.

Mouth mask is the simplest a kind of open respirator.Mouth mask appears at the hospital of late nineteenth century the earliest, and effect is at that time to prevent that medical personnel from being infected by bacterium at work.1918, the large Influenza Outbreak of Spain, mouth mask from hospital enter into ordinary other.Use the object of mouth mask to be just, with a kind of utensil, people's mouth and nose chamber and extraneous air ambient is isolated, stop the foreign matters such as suspended particulate of extraneous dust, gas, liquid to enter people's mouth and nose chamber, respiratory system to people damages, at arctic weather, use mouth mask can avoid people's respiratory system to be subject to the intrusion of cold air.It is maximum that people use is the mouth mask made from multilayer absorbent gauze.Separation principle is the gauze by multilayer, and airborne particle is stopped.Common mouth mask has certain limitation in the use, only with multilayer gauze air to external world, isolate, to external world the buffer action of air a little less than, especially to the penetrating of particle that stops diameter in atmosphere to be less than or equal to 2.5 microns, be that milli is unable, and the inner surface of mouth mask gauze directly directly contacts with the skin of user's mouth na-sal cavity surfaces, be unfavorable for protecting extraneous germ and virus, for the intrusion of human body mouth na-sal cavity surfaces.

Positive-pressure type respirator (mask) is a kind of self-supporting gas free-air respirator, be widely used in the departments such as fire-fighting, chemical industry, boats and ships, oil, smelting, warehouse, laboratory, mine, for fireman or the rescue personnel that speedily carries out rescue work, under all kinds of environment such as dense smoke, poison gas, steam or anoxic, put out a fire safely and effectively, rescue and relief work and rescue.The advantage of positive-pressure type respirator is: adopt Open architecture, breath directly enters atmosphere, and because gas supply flow is large, what wearer breathed feels happier; Adopt malleation mode, the pressure in face shield is greater than the pressure of ambient atmosphere all the time, makes extraneous pernicious gas cannot invade wearer's respiratory apparatus, and safety coefficient is higher; And can repeatedly inflate use.Its shortcoming is: utensil is comparatively heavy, and structure is comparatively complicated, especially needs user to carry air bag or gas cylinder as source of the gas simultaneously, service life is shorter, only can maintain the service time of 1 hour, price is comparatively expensive, is unfavorable for promoting the use of to common house person.

Blast type long tube respirator, by face shield, is carried gas circuit, and machine host forms.Its main frame is the vortex jet plane that a kind of motor special drives, and atmosphere enters the circular passage of cross-section variation from suction inlet, to gas outlet compression ejection, through gas transmission long tube, enters face shield, realizes constant current air feed.Feature is the vertebration of vortex jet plane, there is no air valve structure, long service life, and failure rate is low, stable work in work, gas ejection pressure is large, and capacity is large, is equipped with noise reduction and filter on inlet, outlet passage, and delivery air is comparatively clean.Compressed air, can be used to face shield air feed through gas transmission long tube in the adverse circumstances such as anoxic or toxic gas, dense smoke, dust in operation.For example: oil, chemical industry, storage, medical and health, municipal works department.Shortcoming is, main frame is heavy, main frame must be in safety working environment, main frame atmosphere around should meet respiration health standard, user's scope of activities, can only be positioned at and take within the circumference that ajutage is radius, is unfavorable for long-range portably using, cost is high, is unfavorable for promoting the use of to common house person.

Lung capacity (vital capacity, VC) refer to once do the best air-breathing after, then the total amount of the gas of breathing out as possible.Gently, postadolescent's lung capacity is maximum, childhood and the elderly's lung capacity is less, because of the respiratory tract disease cut-out lobe of the lung or suffer from the crowd that pneumoconiosis produces respiratory disorder, lung capacity is less.

Summary of the invention

It is a kind of rational in infrastructure that the purpose of this utility model will provide exactly, be easy to carry, the mouth, nasal cavity that not only can make wearer by closely with isolated from atmosphere, can normal condition autonomous respiration in haze weather, breathing does not have resistance, not only can filter entered lung more than PM2.5 particle in atmosphere, can also filter, kill airborne germ and virus, a kind of anti-haze portable power respirator that can use continuously within the longer period.
