Accompanying drawing explanation
Fig. 1 is the schematic circuit with the concussion time delay circuit of the ozonizer of delays time to control function provided by the invention.
Embodiment
Below by accompanying drawing, technical solution of the present invention is described in detail, but protection scope of the present invention is not limited to described embodiment.
embodiment 1:a kind of ozonizer with delays time to control function, comprise discharge chamber, described discharge chamber and Electrode connection, concussion time delay circuit is set between described discharge chamber and described electrode, the schematic circuit of described concussion time delay circuit as shown in Figure 1, described concussion time delay circuit comprises relay K 1, timer IC555 and transistor T, the power pins of described relay K 1 is connected with the collector electrode of described transistor T, the grounded emitter of described transistor T, the base stage of described transistor T is connected with the signal output pin OUT of described timer IC555, the periphery of described timer IC555 connects concussion time delay circuit, described concussion time delay circuit comprises resistance R1, electric capacity C1, electric capacity C2, diode D1 and diode D2, described diode D1 and diode D2 oppositely forms shunt circuit mutually, positive electricity end and the described resistance R1 of described shunt circuit connect and are connected with the power pins VCC of described timer IC555 afterwards, the negative electricity of described shunt circuit is extremely connected with the trigger pin THR of described timer and threshold value pin TRI, simultaneously, the negative electricity of described shunt circuit is extremely connected with described electric capacity C1 and is connected with the grounding pin GND of described timer IC555 afterwards, the two ends of described electric capacity C2 are connected with the control voltage pin CON of described timer IC555 and grounding pin GND respectively.
And circuit of the present invention has also done following optimization, in the shunt circuit that described diode D1 and diode D2 is oppositely formed mutually, described diode D2 side series resistance R2.Contact resistance R3 between the signal output pin OUT of described timer IC555 and the base stage of described transistor T.Also comprise diode D3, described diode D3 is the diode of one-way conduction, and its positive electrode is connected with the signal output pin OUT of described timer IC555, and its negative potential is connected with the power pins VCC of described timer IC555.
The ozonizer of delays time to control function that what the present embodiment provided have, adopts dutycycle to be the multivibrator of 1 to 7, i.e. 5 minutes output high level, 30 minutes lower levels everywhere.Alternate cycles.555--VIRTUAL timer and R1, R2 and diode D1, D2 is adopted to form oscillatory circuit.During firm energising, because the voltage on C1 can not transition, namely TRI angle is initiated with lower level, 555 timer location, and OUT pin is high level.Transistor T saturation conduction.Relay K A coil electricity, its dynamic circuit connector is got an electric shock closed, can connect high-frequency oscillator and close amplifier power supply, circuit working, generate ozone.After this charged to C1 by R1, D1, the duration of charging is: T fills=0.7R1C1=5*60s=300s.
When the voltage on C1 is charged to threshold level 2/3Vcc.555 timer reset, OUT pin is lower level, and triode T ends, KA coil losing electricity, and moving together contact resets and disconnects, and stops ozone occurring.After OUT pin is lower level, C1 is by the discharge tube electric discharge of D2, R1 and 555 timer inside, and discharge time is: T puts=0.7R2C1=30*60s=1800s.
Determined that C1 is 1000pF above, then R2=1800/ (0.7*1000*10-6) K Ω, nominal value be 2.7M Ω resistance, in addition, R3 is base stage current-limiting resistance, D3 is connected in parallel on KA coil two ends, can when triode T turns off.Form freewheeling path, avoid transistor occurring high-voltage causes and puncture, play a protective role.
