Abstract

The utility model relates to a 185 nano wave disinfector, comprising a push-pull oscillator, a step-up transformer and a strip lamp which can produce 185 nano wave. The push-pull oscillator consists of two transistors and a first coil of a step-up transformer T. A resistor is connected between the bases of the two transistors of the push-pull oscillator. Two capacitors which are connected together are connected between collecting electrodes of the two transistors. The first coil of the step-up transformer is connected in series between the collecting electrodes of the two transistors. Two resistors which are connected together are connected in parallel with the first coil of the step-up transformer. A 185 nano wave strip lamp is connected in series between two ends of a secondary coil of the step-up transformer. The 185 nano wave disinfector has the advantage of no secondary pollution. The 185 nano wave disinfector uses only 1-3 wattages of electric energy, so the energy consumption is low. The 185 nano wave disinfector has the function of sterilizing, disinfecting and deodorizing fruits, vegetables, tea, clothes, quilts, etc. The 185 nano wave disinfector also has the function of sterilizing and disinfecting the germ in the air, so the 185 nano wave disinfector is also an ideal indoor disinfection appliance for preventing respiratory infectious diseases like flu and SARS.

Description

185 nanometer ripple disinfectors

Technical field

The utility model relates to a kind of 185 nanometer ripples that utilize and produce O ₃Decontaminating apparatus with intensive ultraviolet---185 nanometer ripple disinfectors belong to the disinfecting apparatus technical field.

Background technology

Ozonateur on the present domestic market, ozone O ₃Generation all adopt the mode of discharge.Produce O in mode with discharge ₃The time produced a large amount of nitrogen dioxide (NO again ₂), nitrogen dioxide is toxic gas, and people's respiratory tract is had serious injury.Except that producing the nitrogen dioxide toxic gas, also use high temperature (more than 120 ℃ with 600 watts of power supplys).High temperature can only disinfector, all can't carry out disinfection to melon and fruit, vegetable, clothing, Folium Camelliae sinensis etc.

Summary of the invention

The purpose of this utility model is the defective at above-mentioned existence, proposes a kind of 185 nanometer ripples that utilize and produces O ₃185 nanometer ripple disinfectors with intensive ultraviolet.Technical solution of the present utility model: by push-pull oscillator, booster transformer and the fluorescent tube that produces 185 nanometer ripples are formed.Wherein push-pull oscillator is made up of the primary coil of two crystal triodes and booster transformer T, connection electrical resistance between the base stage of two crystal triodes in the push-pull oscillator, capacitor after two of the inter-collector connections of two crystal triodes are joined, the primary coil of booster transformer is serially connected in the inter-collector of two crystal triodes, the primary coil of two resistors after joining and booster transformer mutually and connect serial connection 185 nanometer ripple fluorescent tubes between two ends of the secondary coil of booster transformer.Push-pull oscillator is transformed into high-frequency ac power in order to the 3 volt DC power supplys that battery B (or external direct current power supply) is provided, by booster transformer T this high frequency voltage is boosted again, the fluorescent tube that offers 185 nanometer ripples with a kind of energy as the fight power supply of steady operation of start-up point.Advantage of the present utility model: 185 nanometer ripples are a kind of light waves, and in the range of exposures of this light wave, airborne oxygen is combined into ozone, so there is not secondary pollution.185 nanometer ripple disinfectors only use 1-3 watt electric energy, work at normal temperatures always, have not only saved energy consumption greatly, can also carry out sterilizing to melon and fruit, vegetable, Folium Camelliae sinensis, clothing etc.Can interrupt the Pesticide Molecule chain, make pesticide lose toxicity.The use of 185 nanometer ripple disinfectors is in refrigerator, car, family's hotel room, office, toilet and public place and all can sterilize, sterilization, deodorization, purify air to computor-keyboard etc., and it is again the ideal indoor sterilization apparatus of respiratory infectious diseases such as a kind of energy flu-prevention, SARS

The specific embodiment

Contrast accompanying drawing, this device in order to the fluorescent tube that produces 185 nanometer ripples by custom-designed circuit supply.Mainly by push-pull oscillator, booster transformer and the fluorescent tube that produces 185 nanometer ripples are formed.Wherein push-pull oscillator is formed connection electrical resistance device R between the base stage of crystal triode Q1, Q2 in the push-pull oscillator by two crystal triode Q1, Q2 (model 8050) with the primary coil of booster transformer T ₁, R ₂(resistance 2.4K Ω), the inter-collector of crystal triode Q1, Q2 connects capacitor C ₁, C ₂, the resistor R after the connection ₁, R ₂With the primary coil of booster transformer T and connect serial connection 185 nanometer ripple tube CCFLs between two ends of the secondary coil of booster transformer T.Push-pull oscillator provides cathode fluorescent tube CCFL required power supply.The starting ignition voltage of cathode fluorescent tube CCFL generally at 1000V between the 2000V, rated operational voltage is about 300V, the function of push-pull oscillator be exactly dc source high-efficiency inversion with 3V be the needed high voltagehigh frequency power supply of cathode fluorescent tube.

The power supply of push-pull oscillator provides by the aneroid battery (or chargeable+3V aneroid battery) of+3V or by the low-voltage dc power supply that can connect the 220V power supply.Capacitor C ₁And inducer L composition filter circuit, be used to prevent that the high-frequency signal that push-pull oscillator produces from sealing in dc source.High-frequency and high-voltage power supply of the secondary generation of booster transformer T offers the fluorescent tube of 185 nanometer ripples, and by and produce the ultraviolet and the O of 185 nanometer ripples ₃Owing to driving power is not had specific (special) requirements herein, whole electronic circuit has only been used eight electronic components commonly used, has compact conformation, characteristics such as volume is small and exquisite, reliable working performance.Dc source of the present utility model provides (also available chargeable No. five Ni-MH batteries) by No. five dried electronics of two joint 1.5V, and than compact electronic device LAM type battery commonly used, it is bigger to have a supply current, long service life, the advantage that expense is cheap; Also can prolong the service life of fluorescent tube.
