Specific embodiment

Below in conjunction with accompanying drawing, specific embodiment of the invention is described in further detail, so that technical solution of the present invention is more Should be readily appreciated that and grasp.

Shown in reference picture 1, a kind of energy saving sterilizing cabinet is included shown in the reference picture 2 of cabinet 1, including heater circuit 210 and smelly There is circuit 310 in oxygen, the heater circuit 210 is connected with heater strip, and the ozone generating circuit 310 is connected with ozone generator 320；Also include a single-pole double-throw switch (SPDT), the single-pole double-throw switch (SPDT) includes a stationary contact, the first movable contact and the second movable contact；

First movable contact and the second movable contact are respectively coupled to heater circuit 210 and ozone generating circuit 310；When first When movable contact and stationary contact are electrically connected, the heater circuit 210 works, described when the second movable contact and stationary contact are electrically connected Ozone generating circuit 310 works；

The single-pole double-throw switch (SPDT) K1 is controlled by intermittent driving circuit 400, is controlled by the relay coil K1 in figure There is signal in system, the interrupted output heating signal of the intermittent driving circuit 400 and ozone, when the intermittent driving circuit 400 is defeated When going out heating signal, the single-pole double-throw switch (SPDT) is acted to connecting the first movable contact and stationary contact；When intermittent driving electricity When road 400 output ozone occurs signal, the single-pole double-throw switch (SPDT) is acted to connecting the second movable contact and stationary contact.Described Drive circuit 400 of having a rest includes multivibrator 410, the coupling relay coil of the multivibrator 410, the relay line When enclosing electric, heating signal is exported, during the relay coil dead electricity, output ozone occurs signal.The multivibrator 410 Output end be coupled with indicator lamp.The multivibrator 410 is configured to the multi resonant oscillating circuit being made up of 555 timing chips. The dutycycle of output can be adjusted by adjusting R11.The output end of the multivibrator 410 is coupled with electric capacity of voltage regulation C13.Institute State electric capacity of voltage regulation and be parallel with discharge resistance R12.

Shown in reference picture 4, the circuit introduction to ozone generating circuit 310, the specific annexation of booster circuit 311 and its Function is as follows：An external ac power source interface is provided with, for being connected with family expenses 220V AC powers, its positive input terminal is connected to one Rectifying tube D1, for carrying out halfwave rectifier to external ac power source, the output end of rectifying tube is coupled with first resistor R1, the first electricity The other end for hindering R1 is grounded by a filter capacitor C1, for carrying out voltage stabilizing treatment, the filter capacitor to half wave rectified signal C1 is parallel with resonant component, and the resonant component includes being sequentially connected in series second resistance R2, the 3rd resistor R3 of setting and the second electricity The node for holding C2, the second electric capacity C2 and 3rd resistor R3 coupling has been also coupled to the 4th resistance R4, and the 4th resistance R4 is connected to controllable silicon The control pole of SCR, controllable silicon is used to control static discharge during over-voltage and over-current.As shown in figure 4, also including a transformer 312, become The turn ratio of depressor 312 may be configured as 24: 900 circles, be used to realize boost function, protection switch and a rectifying tube D2, and its rectification is resistance to Pressure value is 15KV, a partial pressure protective resistance be connected on vice-side winding jointly where loop on, multiple side winding be coupled to one it is negative from Electronic generator, for launching ozone with purify air.

Shown in reference picture 5, heater circuit 210 is described in detail, under normal circumstances, heater strip RL conductings, but once connect Receiving very thermal signal acts relay coil K, so that it may so that relay normally-closed contact K disconnects, cause heating to stop.Emitter-base bandgap grading coupling Close trigger IC2 and be preferably JEC-2, RT can use MF12-1 type negative tempperature coefficient thermistor RT devices, potentiometer preferably with The organic solid scattered tune potentiometer of WSW types, diode can use IN4148 type switching diodes, and LED can typical circular emitting red light Diode, relay JRX-13F miniature relays, S is the small-sized toggle switch of double-pole.When reactor temperature is higher, bear Temperature coefficient thermistor RT devices resistance reduces, and when Aerobic Pond internal temperature is higher, RT resistances are smaller, and it is with potentiometer RP groups Voltage divider, regulation RP just can very easily determine the control point of reactor water temperature, add Aerobic Pond temperature control to be made In 30 degrees centigrades, when at this moment regulation potentiometer makes reactor higher than this temperature, JEC-2 circuits upset, relay K inhales Close, the K trippings of its normally-closed contact, reactor heater strip RL power-off, heating stops.Temperature is gradually reduced, when temperature is less than control temperature When spending, due to thermistor resistance increase, so when JEC-2 inputs current potential be less than 2.1V, JEC-2 upset, make relay Release, normally-closed contact is switched on the power supply of R2, Aerobic Pond is heated；When inside rises to control temperature again, circuit is again Secondary upset, the power supply of cut-out heater strip RL, goes round and begins again, and realizes thermostatic control, due to being related to coupled bistable trigger to overturn During have return difference, although this makes temperature control precision not high, there is a constant interval, it is highly beneficial because it can keep away Exempt from the generation for causing relay flutter to manifest when temperature is in control point critical value.Change the resistance of R0, returning for circuit can be changed Difference.

Certainly, it is more than representative instance of the invention, in addition, the present invention can also have other various specific implementations The technical scheme that mode, all use equivalents or equivalent transformation are formed, all falls within the scope of protection of present invention.
