A kind of ozone virus killing generator

Technical field:

The utility model relates to a kind of ozone generator.

Background technology:

The employed transformer oscillating circuit of general ozone generator all needs to feed back winding usually provides necessary appropriate phase of circuit oscillation and driven amplitude; when load takes place unusual or magnetic core of transformer takes place unusual when saturated; because the turn ratio of transformer feedback winding is fixed; circuit FEEDBACK CONTROL ability and speed are limited, and often circuit damages because of overload easily.Especially when circuit load is the gas discharge class device work of ozone generator, because the nonlinear flash-over characteristic of gas reaches and causes burning of drive circuit or device overload easily, or produces pernicious gas.The feedback winding of the transformer inductance oscillating circuit that the ozone virus killing circuit that generator adopted of the present utility model cancellation is conventional; by special Phase Processing technology and power control resist technology; improved the adaptive capacity of power oscillation drive circuit greatly to load; and has a good circuit protection Performance And Reliability; overcome the shortcoming of traditional transformer inductor oscillating circuit effectively, in the middle low power ozone generator is used, good effect has been arranged.

Summary of the invention:

Goal of the invention of the present utility model is to provide a kind of oscillating circuit operating state ideal, can guarantee the drive circuit power output stable, can blasting not take place because of the acute variation of load and burn out the ozone virus killing generator of excitation driving transistors.

The utility model is to realize like this, comprise the transformer oscillating circuit, ozone generator, the transformer oscillating circuit comprises resistance R 1, resistance R b, resistance R _ f, resistance R p, resistance R e, capacitor C f, switching diode D at a high speed, triode Q1, triode Q2, triode Q3, common electrical sense transformer T, wherein the other end of the resistance R 1 that links to each other with power supply of an end links to each other with the emitter of triode Q2, the base stage of triode Q2 is leaded up to resistance R b ground connection, another road is by the resistance R _ f of serial connection, capacitor C f links to each other with the other end of the common electrical sense transformer T that an end links to each other with power supply, the collector electrode of triode Q1 links to each other with the other end of common electrical sense transformer T, the base stage of triode Q1 links to each other with the collector electrode of triode Q2, the emitter of triode Q1 is by resistance R e ground connection, the collector electrode of triode Q3 links to each other with the collector electrode of triode Q2, the base stage of triode Q3 is by the resistance R p of serial connection, switching diode D at a high speed links to each other with the emitter of triode Q1, the grounded emitter of triode Q3, the power supply output of common electrical sense transformer T links to each other with ozone generator.During work, when power on circuitry, it is excitation driving transistors Q1 starting impulse electric current that starting resistance Rb makes the faint conducting of transistor Q2, Q1 amplifies this electric current and produce induced voltage on the L1 of inductance T excitation winding, the base stage that is added to transistor Q2 behind this induced voltage process feedback capacity Cf and the feedback resistance Rf is amplified, and transistor Q2 carries out paraphase amplification back to this induced voltage to be provided powerful driving and make it be operated on off state for excitation transistor Q1 base stage.The operating current of excitation transistor Q1 forms current sampling voltage on its emitter resistance Re, be added to transistor Q3 base stage after the resistance R p shaping through switching diode D and series connection with it, through amplifying the back switching pulse width of excitation transistor Q1 is adjusted, thereby cut down pulse amplitude effectively, prevented the destruction of high impulse wave amplitude electric elements.When load abnormal, the induced voltage of the excitation winding of each cycle of oscillation, the electric current that reaches load changes direct quick control excitation driving transistors Q1 on off state, thereby adapts to the variation of load very effectively, simultaneously oscillating circuit is carried out safeguard protection.

Here, more stable in order to make circuit working, also be provided with the other end ground connection of the capacitor C 1 that capacitor C 1, one end links to each other with power supply.Like this, the electric current of DC power supply is through after the filtering of capacitor C 1, and electric current is more stable, has guaranteed that circuit working is more stable.

The switching regulator free inductance power oscillating circuit is a kind of employing inductance coil, does not have the novel power-type electro coupled oscillator circuit of auxiliary feedback coil.Its operation principle is directly to utilize the back-emf voltage of common inductance coil, by obtaining the required perfect switch pulse of vibration of excitation driving transistors after the negative circuit processing, guarantee that oscillating circuit is in desirable operating state, produce of the conversion of high-power low-voltage DC the high voltagehigh frequency alternating current.Circuit also detects and controls the peak working load electric current of excitation driving transistors simultaneously; guarantee the stable of drive circuit power output; can blasting not take place because of the acute variation of load and burn out the excitation driving transistors; during when load abnormal, by short circuit or human body accidental shock; this circuit can enter the intermittent oscillation pattern rapidly; power device is protected automatically, after load is normal, can be resumed work automatically again.

The utility model compared with the prior art, have oscillating circuit operating state ideal, can guarantee the drive circuit power output stable, can blasting not take place because of the acute variation of load and burn out the advantage of excitation driving transistors.
