Description
Technical field
The utility model is specifically related to the air purifier with formaldehyde detection function.
Background technique
Haze weather is a kind of atmosphere pollution state, and haze is exceeded to suspended particulate substance contents various in atmosphere general
Statement, especially PM2.5(equivalent aerodynamic diameter are less than or equal to 2.5 microns of particulate matter) it is considered as causing haze sky
" arch-criminal " of gas.With the deterioration of air quality, thick weather phenomenon increases, and harm aggravates.Chinese many areas are yin
Haze weather phenomenon is incorporated to mist together as diastrous weather early-warning and predicting, is referred to as " haze weather ".Fog seems mildly, the inside
It but include acid, alkali, salt, amine, phenol etc., Yi Jichen containing the various fine graineds being harmful to the human body, noxious material up to more than 20 kinds
Angstrom, pollen, acarid, influenza virus, tubercle bacillus, pneumococcus etc., content is tens times of normal atmospheric water droplet.With mist phase
Than haze is bigger to the harm of the health of people.Due to granular tiny in haze floating particle object diameter generally 0.01 it is micro-
Rice is hereinafter, directly can enter bronchus or even lung by respiratory system.So haze influence it is maximum be exactly people breathing system
System, caused by disease be concentrated mainly in the diseases such as respiratory disease, cranial vascular disease, nasal cavity inflammation.Meanwhile haze weather
When, air pressure reduction, Inhalable Particulate abruptly increase, air flow property are poor, harmful bacteria and the viral speed spread to surrounding
It spends slack-off, causes virus concentration in air to increase, the risk of transmission is very high.Haze causes air quality to decline, to people
With very big harm.
Meanwhile as the industrialized development in China and population are continuously increased, pollution is also got worse therewith.In building,
The pollutant generated due to more and more magnificent finishing and some other factor forms indoor air quality serious
It influences, for these pollutants to the respiratory system of human body, cardiovascular system and nervous system have serious evil, in automobile, air
Because the infiltration of exhaust gas and distributing for interior decoration materials, VOCs(formaldehyde, acetaldehyde, acetic acid, benzene class, ammonia, nitrogen oxygen is discharged in engine
Compound, acetone, dimethylbenzene etc.) etc. pollutants, reach quite high concentration sometimes.So designing and developing in decontamination chamber
The device of pollutant in surrounding air is a urgent problem to be solved.But the purification of current indoor air-purification device

Catalyst emission tip.The anion emission tip of anion generator releases a large amount of electronics at high speed, and electronics can not be permanent
Being present in air can be captured at once by the oxygen molecule in air, to generate air negative oxgyen ion.Turbofan multiplication air
High wind is generated, anion generator is sucked, the anion cooperation turbofan of generation uses, and negative ion concentration is greater than normal air
Clarifier.
Anion can neutralize cation, restore polluter, nitrogen oxides, formaldehyde and cigarette etc. from atmosphere
The active oxygen (oxygen radical) of generation；Make positively charged floating dust in air without settling after charge；Weaken electromagnet radiation, thus
Environment is allowed to be purified.The aerial movement of anion is "Z"-shaped.And conveying negative electrical charge is to bacterium, dust, cigarette
Mist particle and water droplet etc..Charge glomeration in conjunction with these particle phases, then falls into ground, to purify air.Especially
The floating dust for being the particle to as low as 0.01 μm of partial size and being difficult to remove, such as the agglutination effect of smoke from cigarette, sensitization particle are obvious,
Relaxation effect can be played to anaphylaxis Hay Fever, bronchial asthma, upper respiratory tract mucositis etc..Anion also has antibacterial effect
Fruit after antifungal mechanism is anion in conjunction with bacterium, makes bacterium generate the change of structure or the transfer of energy, causes bacterium dead
It dies.
Puigging is additionally provided on the inner wall of shell 6, puigging selects PANHOO gradient acoustical cotton, made by polyester fiber
It forms, varying density is realized using heat treatment public law, soundproof effect is better than traditional material such as glass fibre, rock wool, sponge.
Minimum noise in use process will not bother the normal work and rest of people.
Air purifier with formaldehyde detection function use process is as follows:
Power supply is connected, room air enters the sky with formaldehyde detection function under turbofan effect, through air inlet
Gas purifier.At this point, installing connecting conduit and formaldehyde examination pipe on front housing, the turbofan in air cleaning unit is utilized
Air draught effect promotes air to enter in the formaldehyde examination pipe in formaldehyde examination device, joined PARA FORMALDEHYDE PRILLS(91,95) height in formaldehyde examination pipe
The colour reagent of sensitivity colour developing, can accurately indicate formaldehyde in air content, color is deeper to illustrate that content of formaldehyde is higher.
Sucking air purifier in air successively through activated carbon filter layer and HEPA filtering meshes filter out formaldehyde, ammonia,
Then the hazardous solids particle such as the pernicious gases such as carbon monoxide and smog, dust, bacterium passes through anion generator.Anion
The anion emission tip of generator releases a large amount of electronics at high speed, and can not be present in for a long time in air at once can be by for electronics
Oxygen molecule in air captures, to generate air negative oxgyen ion.By the negative oxygen ion band of generation when air is flowed to air outlet
Air cleaning unit out enters the room.
It, cannot the above content is specific preferred embodiment further detailed description of the utility model is combined
Assert that the specific implementation of the utility model is only limited to these instructions.For the ordinary skill of the utility model technical field
For personnel, without departing from the concept of the premise utility, a number of simple deductions or replacements can also be made, should all regard
To belong to the protection scope of the utility model.
