Description

Self-cleaning microphone
Technical field
The utility model relates to a kind of self-cleaning microphone, is specifically related to a kind of self-cleaning microphone based on ultraviolet catalytic sterilizing technology.Utilize thin-film reinforcement photochemical catalyst microphone surface to carry out the microphone of degree of depth sterilizing automatically.
Background technology
In public, the microphone instrument that is absolutely necessary.But in most of the cases, microphone is not thorough in unmanned cleaning in the back of finishing using or sterilization.Particularly the microphone of KTV or the teaching usefulness microphone, owing to contacted by a large amount of all kinds of crowd, microphone carries various germs easily after repeatedly using, such as, microbes such as tubercle bacillus, Escherichia coli, influenza virus and hepatitis B, this certainly will influence the healthy of follow-up user, also makes microphone become one of main media of public arena bacterium and viral communication.
At present, the processing of microphone mainly is to put sponges cover or wiping disinfectant on its metal guard on the market, though these processing methods can realize the sterilization processing of microphone to a certain extent, all has the defective of different aspects.On microphone, directly put sponges cover, need often to change sponges cover, and can not sterilizing, its poor processing effect; Can corrode the microphone surface metal and can not thoroughly dispel the bacterium and the virus on microphone surface at microphone surface wiping disinfectant.
The purpose of this utility model is to overcome the deficiency in the existing microphone sterilizing technical method, proposes a kind of brand-new safe and reliable self-cleaning microphone based on ultraviolet catalytic sterilizing technology.
The utility model content
The utility model is exactly to overcome frequent replacing sponges cover in order to address the above problem, and can not sterilizing; Can corrode the microphone surface metal and can not thoroughly dispel the bacterium on microphone surface and the problem of virus at microphone surface wiping disinfectant, a kind of self-cleaning microphone based on ultraviolet catalytic sterilizing technology is provided, fully utilize the strong oxidation disinfection of ultraviolet sterilization and photocatalysis, thoroughly dispeled the various bacteriums and the virus on microphone surface.This utility model is applicable to public places such as school, hotel, KTV.
Principle of the present invention:
In the sterilizing process, uviol lamp emission ultraviolet lighting is mapped to the semiconductor light-catalyst that is evenly distributed on the substrate, makes microbes such as virus on the microphone, bacterium at first be suppressed active by ultraviolet irradiation or kills; Simultaneously, semiconductor light-catalyst is subjected to the ultraviolet light irradiation of energy greater than its forbidden band energy, electronics on its valence band (e-) is excited and is passed forbidden transition to generate light induced electron (e-) to its conduction band, on valence band, then generate photohole (h+) accordingly, these light induced electrons and photohole have strong reducing power and strong oxidability respectively, their free migrations are during to catalyst surface, light induced electron forms superoxide anion with the dissolved oxygen effect that is adsorbed on the Nano semiconductor particle surface, and photohole will be adsorbed on the hydroxide ion and the water of catalyst surface and be oxidized to hydroxyl free radical.When organic microbials such as bacterium and virus during at the contact semiconductor photochemical catalyst, a large amount of free hydroxyl of its surface aggregation are oxidized to H with organic pollution rapidly 2O, CO 2, innocuous substance such as inorganic salts; Simultaneously, this a large amount of free hydroxyl is also captured the protium (H) in the cell membrane of microbe etc. rapidly, the cells of microorganisms film is decomposed, and materials such as further biolytic protein, carbohydrate and DNA, thereby make that the microbes such as bacterium on the microphone can thoroughly be degraded in second or kill at 1-30, the microphone of handling well at last can be realized safe handling.
The technical problem of the required solution of the utility model can be achieved through the following technical solutions:
Self-cleaning microphone comprises the microphone handle, it is characterized in that, described microphone handle upper end is an extension, and photocatalysis membrana and uviol lamp are set in the extension, and described uviol lamp is with the ultraviolet light protection tube outward;
On the described microphone handle shift knob is set, shift knob is connected with circuit board, and circuit board is installed in the microphone handle, and described circuit board is connected with power supply.
Described photocatalysis membrana is a network structure.
Power supply is the 3.3V chargeable lithium cell, and quantity is 2 joints.
Uviol lamp of the present utility model comprises that can launch dominant wavelength is the xenon lamp that is lower than the 360nm ultraviolet light, low pressure mercury lamp etc., and optimum is 254nm, 185nm uviol lamp.
Photocatalysis membrana of the present utility model be can be ultraviolet ray excited semiconductor light-catalyst, specifically comprise: titanium dioxide and through nitrogen mix, the modified titanium dioxide photocatalyst of PROCESS FOR TREATMENT such as silver mixes, gold doping, load on the titanium-base, profile is netted.
The beneficial effects of the utility model:
The utility model is compared similar technical advantage:
(1) combines the effect of ultraviolet light irradiation and photocatalysis, it is existing ultraviolet photolysis effect in the course of reaction, the photocatalysis strong oxidation is arranged again, remedied sterilization that conventional ultraviolet technology exists not thoroughly, form the potential safety problems such as biomutation of anti-ultraviolet.
(2) have sterilizing speed faster, sterilizing time is less than 30s, can thoroughly kill the bacterium, virus on microphone surface etc.
(3) nontoxic, harmless, safe and reliable to human body, final product is carbon dioxide, water and other innocuous substances, can not produce secondary pollution.
