Description

Ozone water-purifying device power source special

The utility model relates to the used power supply of device that adopts corona discharge process to make ozone, especially is exclusively used in the discrete power of preparation ozone water device.

Ozone water has very strong oxidation characteristic, and the bacterium that can fast and effeciently disappear does not extremely have any residue, decomposes deleterious organic and inorganics.China Anshan static institute makes a kind of ozone water-purifying Sterilizers, ozone is to adopt the corona discharge process manufacturing, principle of work is: city's electrical network alternating-current is become low pressure through transformer, rectifying and wave-filtering becomes direct current again, be input to ozone water device as power supply by outer guide line, circuit part in the ozone water device becomes high-frequency ac to DC converting again, becomes device through boosting and boosts, and obtains corona discharge and makes the necessary high-frequency and high-voltage alternating-current of ozone.This method, the transformer in the power supply is an Industrial Frequency Transformer, operating voltage and frequency are generally 220V or 110V, 50Hz or 60Hz, the voltage height, frequency is low, and volume of transformer and weight are then just all very big, and efficient is also low, overall cost height.

The utility model purpose is to provide a kind of power supply, directly exports the high frequency low voltage alternating-current, can directly import step-up transformer, obtain corona discharge and make the required high-frequency and high-voltage alternating-current of ozone, the volume and weight of power supply reduces widely, and efficient is also high, the overall low advantage of cost.

For reaching above purpose, the utility model adopts the switch power supply principle of work, directly city's electrical network AC rectification is filtered into direct current, be transformed into high-frequency ac by switch circuit again, by the transformer transformation, obtain the reliable high frequency low voltage alternating-current of security, draw by output lead, as power supply, for the ozone water device electricity consumption.Whole power supply includes: shell, power input, circuit, output lead, circuit includes: rectifying and wave-filtering part, transformer, switching tube, control section is characterized in that: the input terminus of rectifying and wave-filtering part directly and city's electrical network alternating-current join; One utmost point of primary winding and the positive pole that rectifying and wave-filtering is partly exported are connected, and another utmost point is connected through the negative pole of switching tube and rectifying and wave-filtering part; Positive pole and the negative pole of partly exporting in rectifying and wave-filtering connected at the two poles of the earth respectively behind the back coupling winding differential concatenation diode; The circulate conducting constantly and closing of the opening and close of switching tube, the high-frequency signal that control section produces, driving switch pipe by the control part control of assigning to.The DC converting of partly being exported by rectifying and wave-filtering becomes high-frequency ac, is coupled to the output winding through transformer, obtains the high frequency low voltage unsteady flow.

Power supply according to the utility model making, owing to be directly city's electrical network AC rectification to be filtered into direct current, be transformed into high-frequency alternating current again, by the high-frequency transformer step-down, saved heavy Industrial Frequency Transformer, when utilizing the high frequency transformation, the high-frequency transformer volume is little, the efficient height, the characteristics that cost is low have reduced the volume and weight of power supply widely.Again since power supply output be high-frequency alternating current, can be directly inputted to the step-up transformer in the ozone water device, the required high-frequency and high-voltage alternating-current of ozone is made in the corona that obtains powering, saved in the ozone water device so again, direct current is transformed into the circuit of high-frequency alternating current, reduce the volume of ozone water device, reduced cost generally.

Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail.

Fig. 1 is a profile features synoptic diagram of the present utility model.

Fig. 2 is the circuit theory feature synoptic diagram in the utility model.

As shown in Figure 1, the utility model mainly is made of shell 1, circuit 2, output lead 3 and power input 4, and this discrete form is to consider from safe in utilization, make ozone water device and civil power net height press away from and isolate.Power input 4 can directly be mounted in the plug on the shell 1, also can draw plug again by lead.

Principle of work of the present utility model, as shown in Figure 2, rectifying and wave-filtering part 5, directly city's electrical network AC rectification is filtered into direct current, the elementary winding 6 of transformer 7, connect the positive negative output of rectifying and wave-filtering part 5 through switching tube 10, behind the back coupling winding 9 differential concatenation diodes, connect the positive negative output of rectifying and wave-filtering part 5, when switching tube 10 conductings, rectifying and wave-filtering part 5 output voltages just are added on the elementary winding 6, export to secondary winding 8 through transformer coupled, while transformer winding inductance is storage power also, feedbacks winding 9 because diodes in reverse series is in off condition.When switching tube 10 by the time, be stored in that magnetic field energy must discharge in the transformer, a part is by secondary winding 8 outputs, polarity of voltage is to instead, so just can obtain the interchange output of low pressure, the redundance magnetic field energy then by feedbacking winding 9, sends back to rectifying and wave-filtering part 5 through diode in addition.By the conducting of trip switch pipe 10 and the frequency of ending, just realized frequency transformation, obtain required high frequency low voltage alternating-current.The selection of operating frequency should because be operated in below the 10KHz, can produce audio frequency drone noise more than 10KHz, can make people's brains dizzy for a long time, and operating frequency preferably is chosen in more than the 18KHz.The conducting of switching tube 10 with by controlling by control section 11, control section 11 generally is an oscillatory circuit, produces high-frequency signal, driving switch pipe 10 circulate conducting constantly with end.The driving switch pipe circulate conducting constantly with by vibration two kinds of forms, the one, self-excited type arranged.The 2nd, separated exciting, for self-excited type, transformer 7 must increase the feedback winding.
