Description

Portable electric air cleaning machine

One, field under this technology:

Belong to mechanical & electrical technology field

Two, background technology

Air and the mankind's existence is closely bound up, and it participates in the processes such as gaseous metabolism, metabolism and body heat regulation of human body directly.The air that people breathes every day is about liter more than 10,000, and reduced mass is about 12.9kg, is equivalent to required food and 10 times of amount of drinking water every day.Along with the fast development of modern industry and traffic, the discharge of flue dust and vehicle exhaust etc., has surmounted the self-cleaning boundary of atmosphere, and what come one after another is but a very severe problem---atmosphere pollution.The pollutant larger to atmospheric pollution effect has: oxysulfide, nitrogen oxide, hydrocarbon, oxycarbide, dust etc.Oxysulfide is acidic materials, from for example oil, burning of coal of sulfurous fuels, mainly refers to sulfur dioxide and sulfur trioxide.They can form under certain condition to the very harmful aerosol of the mankind and acid rain.Sulfur oxide is contaminated environment not only, and seriously endangers people's health, can stimulate human respiratory, makes narrow diameter, and resistance increases, and causes the resistivity that bacterium is infected to decline, and the blood forming organs such as damage marrow, spleen, destroy body intracellular metabolic.Occur in Britain's world-shaking " smog episode in london " in 5 to 8 December of nineteen fifty-two and just belong to this class air pollution example disastrously, in short four days, bronchitis, pneumonia, asthma, coronary heart disease are increased sharply suddenly, ruined people's life more than 4000, even if somebody's misfortune is unable to escape in two months after malicious mist, there are successively more than 8000 people to be murdered.Nitrogen oxide and hydrocarbon are mainly the waste gas being gone out by motor vehicle emission, through solar ultraviolet, irradiate and the photochemical reaction of generation series of complex, form photochemical fog, this is a class ozone, nitrogen oxide, aldehyde, ketone, Peroxyacetyl nitrate and aerocolloidal oxidative pollutant thereof.Oxycarbide comprises carbon monoxide and carbon dioxide, and mainly the burning by fossil fuel discharges.The infrared ray of the carbon dioxide gas physical efficiency strong absorption sun, raises earth surface temperature, causes " greenhouse effects ", changes and has destroyed the ecological balance.Carbon monoxide colorless and odorless, the affinity of it and hemoglobin is oxygen and hemoglobin affinity 210 times, makes hemoglobin lose the ability of oxygen therapy and cause histanoxia, causes headache, neural paralysis, even life danger.Dust comprises coal dust, metallurgical dust, silica dust etc., and wherein diameter is floating dust below 10 μ m, is attached to polycyclic aromatic hydrocarbon compounds such as benzo (α) pyrene on floating dust and is the strongest known carcinogenicity material at present.And can discharge benzo (α) pyrene in the combustion processes such as kerosene, gasoline, diesel oil.As the concentration of benzo in atmosphere (α) pyrene increases by 6.2 μ gm-3, the lung cancer mortality of this area will double.Floating dust is easily deposited on lung through respiratory tract in addition, as dissolved, will directly immerse blood, makes septicemia.In sum, the main source of atmosphere pollution is the burning of fuel.Atmosphere pollution depends primarily on the physicochemical property of pollutant on the impact of health.Different atmosphere pollutions is on the impact of human body and endanger different.The disaster that atmosphere pollution brings to the mankind and harm are very serious.

The source of atmospheric pollution is exactly the source of atmosphere pollution, mainly contains following three:

(1) industry: industry is an important sources of atmosphere pollution.Industrial discharge is various to the pollutant kind in atmosphere, and character is complicated, has flue dust, sulfur oxide, nitrogen oxide, organic compound, halide, carbon compound etc.Wherein have plenty of flue dust, have plenty of gas.

(2) life cooking stove and heating boiler: in city, a large amount of domestic life cooking stoves and heating boiler need to consume a large amount of coal, and coal will discharge the harmful substance atmosphere pollutions such as a large amount of dusts, sulfur dioxide, carbon dioxide, carbon monoxide in combustion process.Particularly in the winter time during heating, often make IA full of smoke, choke and to obtain people's cough, this is also a kind of pollution sources that can not be ignored.

(3) communications and transportation: automobile, train, aircraft, steamer are the main means of transports in the present age, the waste gas that they burn coal or oil generation is also important pollutant.Particularly the automobile in city, measures greatly and concentrates, and the pollutant of discharge can directly be attacked people's respiratory apparatus, very serious to the air pollution in city, becomes one of primary pollution source of big city air.The waste gas of motor vehicle emission mainly contains carbon monoxide, sulfur dioxide, nitrogen oxide and hydrocarbon etc., and first three kind material harmfulness is very large.

Have now a large amount of densely populated live and works in city, city is the most concentrated place of air pollution source just, and a large amount of pernicious gases that produce in relatively narrow and small region, city are difficult to dissipate.Crowd in city has a large amount of time to be active in open air, the airborne dust that the various vehicle exhausts that busy traffic at one's side produces and galloping take up makes the direct feeling of people to the infringement of pernicious gas, so we often can see that a lot of people mask one's nose and mouth with a cloth to reduce the infringement of suffered pernicious gas out of doors.

Mouth mask has the effect of filtration to airborne deleterious particle thing, some mouth mask also has certain protective action to airborne pernicious gas.The load of lung when but the meeting increase user that masks one's nose and mouth with a cloth breathes, the circulation of air resistance of mouth mask can not be too high, have influence on the filter efficiency to suspension in air, also can there are some problems in mouth mask edge and user's face laminating degree, when user exhales in addition, the wet gas of breathing out will see through the fine air-vent of mouth mask discharged to atmosphere, easily in mouth mask inner side, grow various bacteriums, affect respiration health, it is a large amount of damp and hot and surround nose and mouth with different gas of hiding that user can feel in use, therefore the comfort of mouth mask and protection validity still have larger shortcoming for the user.The very fast loss of mouth mask also brings larger use cost.

Three, summary of the invention

When the people in city are movable out of doors, be sought after the portable air cleaner that a kind of individual uses, can continually to user, provide the air through purifying.Particularly for traffic, be subject to the pedestrian of tail gas infringement, the pedestrian of seat of bicycle, electric bicycle, motorcycle is had to great help.

The design is a kind of portable electric air cleaning machine, and it is flowed through air pumping after air-treatment and clean unit and for user, see through the breathing mask that is covered in nose and mouth and suck with miniature electric air pump.The breathing of considering people is pulsed, and the work of miniature electric air pump is continuous, when user exhales, the air after purifying is stored and be conducive to obtain purifying air of q.s when user is air-breathing.Otherwise just need miniature electric air pump to have enough flows to meet user's instantaneous larger air feed demand when air-breathing, this will require to join larger miniature electric air pump, larger air-treatment and clean unit, larger power supply, this both can increase cost, also can increase the weight and volume of whole portable air cleaner, be contrary to portable object.

As the air after purifying is stored in the container of a rigidity, because former container can retain air, air after newly-increased purification can cause increasing of container inner pressure, can flow through under the effect of the pressure exhaust outlet of breathing mask of part air spills into atmosphere, and when user is air-breathing, can in rigid container, form negative pressure, affect the release of air in container.If reach the effect of gas storage, need larger rigid container.

The design adds a flexible air bag after air-treatment and clean unit, air after purifying when user exhales can fill air bag in the situation that not increasing in air bag gas pressure, when user is air-breathing, air bag can fully discharge the pure air in air bag under to the extruding of air bag at atmospheric pressure, makes user can not feel for unsaturated vapor and be subject to larger air-breathing lung load.

Portable air cleaner is to flow through air-treatment and clean unit purifies with miniature electric air pump pumped air, therefore with respect to mouth mask, can alleviate the load of user lung, miniature electric air pump can provide larger supply gas pressure to be conducive to air to overcome the resistance while flowing through air-treatment and clean unit, can configure the better air-treatment of clean-up effect and clean unit.
