Abstract

The utility model discloses a miniature domestic sterilizer which is composed of a power, a timing control circuit and a high voltage discharging circuit, wherein the power is divided into two ways to supply, one way is supplied to the timing control circuit after voltage reduction and rectified voltage stabilization, and the other way is supplied to the high voltage discharging circuit after current limitation and rectification. The high voltage discharging circuit is provided with a group of series boosting transformers and is respectively connected with an ozonizer, an ozone restorer, a boosting transformer, a charging and discharging capacitor and controlled silicon in the lower grade of the high voltage discharging circuit to form a charging and discharging loop. The utility model has the advantages of small volume, convenient operation and high efficiency of generating and reducing ozone, and uses the performance of ozone sterilization to carry out the sterilization for teacups, foodstuff such as fruits, etc. and miniature tools in families.

Description

Miniature household sterilizer

This utility model belongs to a kind of small household appliances product, is mainly used in the sterilizing of food and tableware.

Healthy for people at first is noted that dietetic hygiene, so, adopt the germ-resistant product of ozone technology to enter huge numbers of families very soon, see at present be a kind of cost than higher ozone type disinfection cupboard, its volume is big, cost is high, so price is also high.Nowadays all kinds of household appliances continue to bring out and put on market, and most residents are owing to the restriction of economic condition, so the diet disinfector can't spread to family very soon.In addition, existing ozonization and ozone reduction technology be full maturity not, especially ozone reduction technology, what mainly adopt is the thermal reduction mode, and theoretically, reaching fully, reduction must be heated to 300 ℃, have only 55 ℃ and add thermal reduction now usually, so produce two inevitable defectives, one, the reduction not thorough, the ozone residual quantity is big; Air expanded by heating when two, heating, ozone overflows from container, and abnormal smells from the patient is difficult to hear.

Order of the present utility model is in order to overcome above-mentioned said defective, to design a kind of volume a kind of miniature household sterilizer little, low in energy consumption, simple in structure, and adopts a kind of new ozone reduction technology in design, makes it reduction thoroughly, is destitute of smell and overflows.

This utility model is to realize with following technical measures: this miniature household sterilizer, be by power circuit, timing control circuit and high voltage discharge circuit are formed, and wherein power circuit is divided into two-way, and one the tunnel is to offer timing control circuit behind blood pressure lowering, rectifying and voltage-stabilizing; One the tunnel is to offer high voltage discharge circuit after current limliting, rectification, described high voltage discharge circuit is to have one group of booster transformer T2 and T3 that is connected in series mutually, the T2 secondary end is connected to ozonator E1, T3 level termination one discharge terminal E2, elementary back formation one charging and discharging circuit in parallel of connecting with the anode of controlled extension SCR respectively of T2 or T3 with charge and discharge capacitance C8.Outfan in controllable silicon SCR is connected in series a shunt resistance R9.

Ozonization is compared with the alternate manner sterilization, it has two big advantages, the one, energy-conservation, the 2nd, the plastic of can sterilizing, and the technological difficulties of ozonization are the ozone reduction technology, because technical immature, so often there is unpleasant abnormal flavour to overflow in the ozonateur, these problems are perplexing manufacturer always, and this utility model has been owing to adopted the electrion technology to reduce, thereby have solved defective of the prior art.In addition, its volume is little, simple in structure, power consumption is low, popularizes easily and uses.

This utility model description of drawings:

Fig. 1 is this utility model circuit block diagram.

Fig. 2 is this utility model circuit theory diagrams.

In conjunction with the accompanying drawings structure of the present utility model and operation principle thereof are described further:

As shown in Figure 1, 2: this disinfector divides three parts, electric former part, timing controlled part, electrion part.The 220V alternating current divides two the tunnel, the one tunnel to be through the transformator blood pressure lowering, enters V1～V4 rectification, supplies with timing control circuit again after the V12 voltage stabilizing; High voltage discharge circuit is given for the 320V pulsating direct current in another road after the C5 current limliting enters V5～V8 rectification, make ozone take place and the discharge reduction.

Shown in Figure 2: N1 is 4060 binary counters, and it and R5, R6, C7 constitute intervalometer, and each foot turns over height successively by binary system.Start working when trigger switch K1 presses, the K3 stop key is normally closed, and 3 feet of N1 are low level, relay J 1 adhesive, entire circuit works on after trigger switch K1 unclamps, and this moment, relay J 2 was not worked, high-pressure section T2 conducting, ozonizer E1 work produces ozone; When first timing arrives, the 2 foot level of N1 turn over height, and function control switch K2 is in closure, the adhesive of J2 conducting at this moment, and T2 outage so, ozonizer E1 quits work, and the T3 conducting, electric arc terminal E2 work, reduction ozone; When second timing arrives, the 3 foot level of N1 turn over height, and relay J 1 outage is unclamped, and circuit quits work.At this moment R2, LED have constituted the duty indication.

C5 is a current limiting capacitance, 220V exchanges after V5～V8 rectification provides the pulsating direct current of a 320V to capacitor C 8 chargings to high-pressure section, at this moment R7, R8 both end voltage raise, through R7, R8 dividing potential drop, when the last voltage of R8 reaches the controllable silicon SCR gate trigger voltage, the controllable silicon conducting, at this moment C8 is through the primary coil discharge of booster transformer T2 or T3,6000 volts of high pressure of secondary generation at T2 or T3, make ozonizer E1 or discharge terminal E2 work, the while circuit oscillation, capacitor C 8 repeated charge produce 3～4 spikes.V11 is used for protecting controllable silicon, constitutes oscillation circuit simultaneously, and resistance R 9 is that shunting controllable silicon negative electrode is protected controllable silicon to the electric current of gate pole, and guarantees the reliability of circuit, improves ozone simultaneously and takes place and reductive efficient.
