Description

Ozone electronic sterilizer

This utility model belongs to electronic technology field, especially in regard to the O of a kind of air and body surface ₃The electronic sterilization device.

Existing disinfection technology is a lot, roughly has following several: disinfectant solution, far infrared, ultraviolet, radioactive source, ozone etc.There is secondary pollution in chemical agents such as use disinfectant solution, and some occasion incompatibility, in air, use far infrared that air also is not suitable for, and can not be to some sterilisation of objects, as plastic; Burdick lamp or radioactive source are mainly used in present air sterillization, but, a little less than the ultraviolet penetration capacity, aerial sterilization distance is 0.5m only, and it is straightline propagation, to being subjected to the surface disinfection weak effect of object blocks, i.e. sterilization has the dead angle, not thorough, and Burdick lamp costs an arm and a leg, and service life is short; Use radioactive source, as C ⁶⁰ ₀, food and thing commonly used are of little use; In recent years, though also utilize ozone to come disinfectant,, because following several big shortcoming arranged, so that do not replace Burdick lamp and be widely used in the operating room of hospital.1, contour structures is unreasonable, is fixed as the discharge ozone window, the M R difficulty, and ozone discharge tube is owing to the absorption foreign material often need clear normal replacing of wiping and need.2, circuit design is unreasonable, does not produce the above high-voltage pulse electricity of 1500V, so that the ozone amount that produces in the unit interval influences disinfectant time and effect inadequately.3, because ozone, is difficult to diffusion than great, by prior art, it is unbalanced ozone concentration to occur in the air, thereby influence Disinfection Effect, and at high concentration region health is produced and to endanger.

It is not enough in the prior art that the purpose of this utility model is to avoid, and the ozone concentration that designs a speciogenesis is suitable, diffusion evenly and clean the machine that utilizes ozone to carry out disinfection easy to maintenance, the principle of this machinery utilization electrion produces high-concentrated ozone at regional area, kills as airborne antibacterials such as hospital operating room, public place, virus also just like the antibacterial and the virus on some solid objects surface in the food-processing industry.

This utility model can be realized by following measure: a kind of O ₃Electronic steriliser, form by pulse transformer, discharge tube, oscillating circuit, discharge ozone window, of the present utility model being characterised in that: the discharge ozone window is active, at the discharge ozone window electric fan is housed, the alternating current that has 220V, 50HZ is by being connected on the oscillating circuit after the mains transformer blood pressure lowering again.Oscillating circuit is 220V, the 50HZ alternating current power supply is added on the colelctor electrode of audion T1 the parallel circuit that is connected into by resistance and electric capacity, diode between colelctor electrode and low-tension supply after the interchange output LOW voltage power supply about output 36V behind the transformator is through stabilivolt D3 voltage stabilizing and diode halfwave rectifier.It is to adopt electrion to produce high-velocity electrons (e), the oxygen (O in the ionized air ₂) becoming single oxygen atom (O), single oxygen atom (O) finally is combined into ozone (O ₃) and at discharge tube window installation electric fan, to help the ozone diffusion.Its chemical equation is: O ₃+ e → O+O+e, O+O+O → O ₃Ozone is the strongest oxidant and the disinfectant of generally acknowledging in the world at present, utilizes O ₃Strong oxidizing property and airborne various harmful organic substance and inorganic matter play oxidation reaction, as airborne H ₂S, NH ₃Deng, playing the effect that purifies air, its chemical equation is: H ₂S+O ₃=H ₂O+SO ₂↑, 2NH ₃+ O ₃=3H ₂O+N ₂↑, utilize O ₃Strong sterilization can kill various antibacterials, brood cell and virus.In the production process of ozone, can produce the anion of some, combine with (as the air conditioning chamber) airborne cation under the special environment, can play pure and fresh, the effect that purifies air.

This utility model and background technology contrast have following advantage: volume is little, it is low to consume energy, life-span is long, use, easy to maintenance, and can overcome above-mentioned various shortcoming, particularly shell ozone discharge window is active, is convenient to change, wipe clearly discharge tube, and electric fan is housed at ozone discharge window, to help the ozone diffusion.Killed rate to various antibacterials reaches 100%, killed rate to virus reaches more than 90%, therefore, to replace Burdick lamp and various disinfectant, be widely used in hospital operating room, sterilizing room, food-processing industry, hotel, pharmaceuticals industry, the air sterillization of public place, family and the sterilization of body surface.

Below in conjunction with drawings and Examples this utility model is described in further detail:
