Abstract
The invention provides an ultraviolet disinfection face mask, comprising a supporting piece, at least two ultraviolet LEDs (light-emitting diodes) and a face mask, wherein the ultraviolet LEDs are fixedly arranged inside the supporting piece, and the emitted light of the at least two ultraviolet LEDs has different dominant wave lengths. According to the ultraviolet disinfection face mask, the at least two ultraviolet LEDs having different dominant wave lengths are adopted, on one hand, the disinfection capability of ultraviolet is utilized, on the other hand, the ultraviolet is utilized for exciting the effective oxygenolysis characteristic of photocatalyst to play a broad-spectrum disinfection effect. Meanwhile, through selecting combination of ultraviolet LEDs having different wave lengths, pollutants and microorganisms contained in specific air environment can be removed and killed in a targeted manner.
Description
Technical field
The present invention relates to a kind of amenities, particularly a kind of disinfection by ultraviolet light face shield.
Background technology
Along with LED technology constantly moves to maturity, its range of application expanding day.And ultraviolet LED compares the luminous ultraviolet light source of traditional mercury vapour, have volume little, without mercury pollution, the life-span is long, germicidal efficiency is high advantage.Therefore can be applied in more widely various fields, disinfection by ultraviolet light face shield is also an application wherein.
Photocatalyst is applied in every field widely as a kind of antibacterial coating.It coats substrate surface, the dry rear film that forms.Under the irradiation of specific wavelength, it can react with the oxygen that water or appearance are deposited, and produces hydroxyl free radical (OH) and super cloudy oxonium ion (O).Thereby produce strong catalytic degradation function: can effectively kill various bacteria, antibiotic rate is up to more than 90%, and the toxin that bacterium or fungi can be discharged decomposes and harmless treatment; Various harmful chemicals, odorant can be decomposed or harmless treatment simultaneously, reach purify air, the effect of anti-soil deodorizing.In this course of reaction, photocatalyst itself does not change and loss, has good continuation, and the nontoxic and final product of itself is carbon dioxide, water and other innocuous substances simultaneously, can not produce secondary pollution.
In prior art, a kind of disinfection by ultraviolet light mouth mask is generally ultraviolet auto-sterilizing photocatalytic breathing mask.It comprises face shield and the control member that can adhere to photocatalyst regeneration.Said apparatus is by the ultraviolet ray (350nm ~ 400nm) of energy specific band, the oxygenolysis of exciting light catalyst are provided.Due to the ultraviolet sterilization ability of this wavelength band a little less than, so the sterilizing ability of this face shield is more single, has just brought into play the oxidation Decomposition characteristic of photocatalyst.The sterile mask that another kind has multi-layer filtration material is to utilize the ultraviolet ray of external irradiation or the oxidation of excited by visible light photocatalyst to carry out sterilization, but due to the ultraviolet that can be utilized by photocatalyst in visible ray seldom, only has 3% ~ 5% left and right, therefore cannot give full play to the oxidation Decomposition characteristic of photocatalyst, bactericidal property is poor.
Summary of the invention
The technical problem to be solved in the present invention is single in order to overcome the ultraviolet wavelength that disinfection by ultraviolet light face shield of the prior art sends, the defect that sterilizing ability is poor, provides a kind of its ultraviolet LED to have the disinfection by ultraviolet light face shield of at least two kinds of different utilizing emitted light dominant wavelengths.
The present invention solves above-mentioned technical problem by following technical proposals: a kind of disinfection by ultraviolet light face shield, it comprises a support member, at least two ultraviolet LED and a face shield, its feature is, it is inner that described ultraviolet LED is fixedly arranged on described support member, and the utilizing emitted light of at least two described ultraviolet LED has different dominant wavelength.
Preferably, described ultraviolet LED is evenly distributed in described support member.Equally distributed ultraviolet LED can make various piece in described support member be subject to ultraviolet ray irradiation more uniformly, makes sterilization more thorough.
Preferably, on described support member inwall, symmetry is embedded with two groups of ultraviolet LED that radiative dominant wavelength is different, and the quantity of every group of ultraviolet ray LED is at least one.
Preferably, described in each, the radiative dominant wavelength ranges of ultraviolet LED is 100nm-400nm.
Preferably, having the radiative dominant wavelength of a ultraviolet LED at least is 254nm, and to have the radiative dominant wavelength of a ultraviolet LED at least be 365nm.Wavelength is that the ultraviolet ray of 254nm has good bactericidal action.
Preferably, the interior survey of described support member scribbles one deck for antibacterial coating.
Preferably, described coating is TiO
2.By great many of experiments, draw, the ultraviolet ray of 365nm wavelength is to activate with TiO
2the better selection light source of photocatalyst for semiconductor medium, has stronger photochemical reaction effect, can greatly strengthen the sterilization of described disinfection by ultraviolet light face shield and the removal ability of air pollutants.
Preferably, described support member is column structure.
Positive progressive effect of the present invention is: the present invention adopts at least two ultraviolet LED with different dominant wavelengths, utilize on the one hand the sterilizing ability of ultraviolet ray self, by the efficient oxidation resolution characteristic of ultraviolet ray excited photocatalyst, play the effect of broad-spectrum sterilization on the other hand.Simultaneously can also be by selecting the pointed removal of pollutant that the ultraviolet LED combination of different wave length contain special air environment and microorganism and killing.
