Description
Technical field
The utility model relates to air purifier field, particularly relates to multifunctional air purifier.
Background technology
Air purifier originates from fire-fighting purposes, and 1823, John and charles's Dien were invented a kind of Novel smog protector, can make fire fighter in the time of fire extinguishing, avoid smog invasion and attack. ?
1854, a people who is named as John's Stenhouse made further progress again on the basis of older generation's invention: attempt by several, he recognizes to adding charcoal to filter out from air in air cleaner and is harmful to and toxic gas.
During the Second World War, U.S. government starts to carry out radioactive substance research, and they need to develop a kind of mode and filter out all deleterious particles, to keep air cleaner, scientist can be breathed, so HEPA filter arises at the historic moment.In 20th century 50, the sixties, once very popular without dividing plate high efficiency particle air filter (HEPA), welcome by bomb shelter design and establishing personnel.
The now purification of air purifier on the market should be divided into three major types its operation principle, below the technical Analysis defect and the deficiency that adopt from their operation principles respectively:
First class: passive type purifies class (filter screen purification class)
Cardinal principle is:,, mainly can play Chalk-dust filtering, peculiar smell, toxic gas and kill the effect of part bacterium by built-in strainer filtering air air suction machine with blower fan.Filter screen divides again: control of dust filter screen, remove formaldehyde filter screen, deodorizing filter screen, HEPA filter screen etc.What wherein cost compare was high is exactly HEPA filter screen, and it can play and decompose toxic gas and bactericidal action, particularly suppresses secondary pollution.
Feature: the feature of this series products is that the quality of blower fan function and filter screen determines clean-up effect, and whether the placement of machine and indoor arrangement impact purify complete, and indoor purifying effect is unbalanced, is also difficult to completely, and screen replacing expense is higher.
Second largest class: initiatively purify class (without filter screen type)
Can be divided into silver ion technology, anion technology, non-thermal plasma trap, photocatalyst technology and clean cluster ion ion technology according to the active sterilizing mechanisms of these products.
The first generation, silver ion purification techniques.Be exactly briefly that silver bullion ionization is blown in air to play the effect of sterilization, shortcoming product cost is high, and bacterial inactivation rate is low, and virus is not almost killed to characteristic.
The second generation, anion technology.Cardinal principle is to use static anion releasing, absorption concentrates airborne dust to play depositing dust effect, anion also has the effect that is ionized into ozone to airborne oxygen simultaneously, bacterium is had to certain killing action, shortcoming is only to absorb airborne minority particle, can not absorb pernicious gas, and anion generator inferior also may produce excessive ozone simultaneously, allow on the contrary air quality variation.
The third generation, non-thermal plasma trap.Cardinal principle is, by giving the discharge voltage of gas applied voltage to gas, makes gas breakdown, produces the low-temperature plasma of various strong oxidizing properties, and within the utmost point short time, the pollutant touching divided and taken off.This technology is generally used for industrial waste gas processing, produces secondary pollution after chemical reaction, if will be applied in Household Air Purifier, need to do human body safety test and corresponding secondary pollution treatment technology.
The 4th generation, photocatalyst technology.Photocatalyst is actual is to utilize semiconductor under the irradiation of light, discharges the technology of the free radical of strong oxidizing force.The advantage of this technology is that product cost is lower, and shortcoming is that free radical activity time of causing it to stop in air is shorter, also limited to the killing effect of virus and bacterium.Product representative: great Jin.
The 5th generation, clean cluster ion technology.That airborne hydrone direct ionization is become H free radical and OH free radical by one, the technology of wrapping up again hydrone simultaneously.But actual ion number and degerming, clean-up effect because of concrete condition and the using method in room different.Due to exclusive technology, machine is expensive.
The third-largest class: double purified class (initiatively purify and add passive purification)
Now the air purifier of market adopts multiple technologies and material comprehensive utilization mostly, causes manufacturing expense, usage charges high, even secondary pollution.Because cost is high, adopt miniaturization more, cause detection effect and result of use gap far! Because present air purifier is on the market all to adopt the method for adsorption particle to purify air, cleaning or replacing filter not in time, secondary pollution cannot be avoided, and cleaning or replacing filter have increased consumer's use cost, cause ordinary consumer to keep someone at a respectful distance to air purifier.No matter from technology or cost aspect, air purifier producer all could not solve especially public place air cleaning problem of average family now.
