Description

Electronics purifies sterilizing machine

This utility model relates to a kind of electronics and purifies sterilizing machine.

Existing electronics purifies sterilizing machine and is made up of current-limiting circuit, half-wave rectifying circuit, LC oscillating circuit, trigger impulse circuit, high-frequency and high-voltage system and ozone generating pipe, be connected to reverse conduction triode thyristor after the trigger tube of its trigger impulse circuit, trigger reverse conduction triode thyristor by trigger tube and produce high frequency electric, produce high-frequency high-voltage signal by high-tension transformer, produce ozone by ozone generating pipe again.Above-mentioned reverse conduction triode thyristor is the suitable controllable silicon (as model S3900) that produces the industrial special special use of ozone waveform, is mainly Germany, Japan's production, is difficult on the market at home buy, and belongs in great shortage product; And the price of this reverse conduction triode thyristor doubles than common controllable silicon.Therefore, the electronics purification sterilizing machine that adopts this reverse conduction triode thyristor to make is difficult for popularizing.

The purpose of this utility model is to overcome the deficiencies in the prior art part, provides a kind of convenience of drawing materials, cost electronics low, that easily popularize to purify sterilizing machine.

This utility model is achieved in that it is made up of current-limiting circuit, half-wave rectifying circuit, LC oscillating circuit, trigger impulse circuit, high-frequency and high-voltage system and ozone generating pipe, its controllable silicon that is used to provide high frequency electric in the high-frequency and high-voltage system is common controllable silicon, between this silicon controlled control utmost point and negative electrode, be connected to the resistance that is used for improving the conducting effect, between these silicon controlled negative and positive the two poles of the earth, be connected to the catching diode that is used for eliminating stray wave, to produce the ozone waveform.

Purify sterilizing machine according to above-mentioned electronics, in current-limiting circuit, also be connected to permutator before the current limiting capacitance, be connected to another electric capacity, with the size of control size of current and then control ozone amount by this permutator.

Purify sterilizing machine according to above-mentioned electronics, also be connected to fan by the transformation current rectifying and wave filtering circuit, to get rid of abnormal flavour at power input.

Replace the reverse conduction triode thyristor of industrial special use because this electronics purifies sterilizing machine with common controllable silicon, therefore, draw materials conveniently, cost is low, easily universal, and can produce ideal ozone waveform, and ozone amount is big.

The drawing explanation:

Fig. 1 is a circuit block diagram of the present utility model;
