In an embodiment of the present invention, as shown in fig. 1 to fig. 3, an anion generating circuit at least includes:
the voltage boosting circuit comprises an oscillating circuit, a transformer, a voltage multiplier and a protection circuit which are electrically connected, wherein the oscillating circuit is used for generating signal voltage, the transformer is used for voltage transformation, current transformation and impedance transformation, the voltage multiplier is used for a voltage boosting circuit, and the protection circuit is used for overcurrent and overvoltage protection; the oscillation circuit generates self-oscillation, after the secondary of the transformer outputs pulse high voltage, the pulse high voltage is filtered by the voltage doubler to form direct current high voltage, and when the temperature rises, the protection circuit adjusts the temperature to reduce the temperature, thereby achieving the purpose of temperature compensation.
The negative ion generating circuit comprises a direct current negative ion generating circuit and an alternating current negative ion generating circuit. Wherein, direct current anion generating circuit includes: transformer T1 has N1, N2 and N3 windings, the positive pole of the dc input voltage is connected to one end of N1, one end of N2 and one end of N3 windings, the negative pole of the dc input voltage is connected to one end of capacitor C1, the emitter of transistor Q1 and one end of capacitor C2, the other end of capacitor C1 is connected to the other end of N1 and the collector of transistor Q1, the other end of capacitor C2 is connected to one end of thermistor RT, the base of transistor Q1 and one end of capacitor C3, the other end of capacitor C3 is connected to one end of resistor R1 (for example, the resistance value may be 100R-150R) and one end of variable resistor R2, the other end of thermistor RT is connected to the other end of resistor R1, the other end of variable resistor R2 is connected to one end of capacitor C5 and the other end of N2 windings, and the other end of capacitor C5 is connected to the positive pole of diode D1, The cathode of the diode D2 is connected, the anode of the diode D2 is connected to one end of the capacitor C6 and one end of the resistor R3, respectively, the other end of the capacitor C6 is connected to the other end of the N3 winding and the cathode of the diode D1, respectively, and the other end of the resistor R3 outputs a high voltage.
In the direct-current negative ion generating circuit, an oscillating circuit comprises a transformer T1, a triode Q1, a capacitor C3 and a resistor R2, a voltage multiplier comprises a capacitor C5, a capacitor C6, a diode D1 and a diode D2(2CL71A), and a protection circuit comprises a resistor R3. The working principle of the oscillating circuit is as follows: when the power supply is switched on, the triode Q1 is switched off, and current is injected into the base of the triode Q1 through an N2 winding in the transformer T1, the resistor R2 and the capacitor C3. Transistor Q1 is now on and current flows into the N1 winding of transformer T1. The capacitance value of the capacitor C3 can be selected to be 0.5 uF-1 uF, and because the capacitance value of the capacitor C3 is relatively small, the time for injecting the current of the triode Q1 is short, and the triode Q1 is turned off immediately. When the transistor Q1 is turned off, an induced current is generated on the N2 winding of the transformer T1, and then injected into the transistor Q1 through the resistor R2 and the capacitor C3, and the transistor Q1 is turned on, so that oscillation is cyclically formed. The number of turns of the N3 winding is set to be more than 200 times of the number of turns of the N1 winding, and since the number of turns of the N3 winding in the transformer T1 is about 200 times of the number of turns of the N1 winding, a pulse voltage of about 1800V is generated across the N3 winding of the transformer T1, which is a voltage doubling principle. When the N3 winding of the transformer T1 is at the positive half cycle, the diode D1 is turned on to charge the capacitor C5, and the voltage across the capacitor C5 is approximately equal to the voltage across the N3 winding of the transformer T1, which is approximately 1800V. When the winding N3 of the transformer T1 is at the negative half cycle, the diode D2 is turned on and the diode D1 is turned off. The voltage across the N3 winding of transformer T1 is connected in series with the voltage across capacitor C5 to charge capacitor C6, thus providing approximately 2 times the voltage across the N3 winding of transformer T1 at approximately 3600V across capacitor C6. For example, the transistor Q1 may be 2SD1616A or other types that meet the requirements, and the type of the transistor Q1 is not limited herein. The models of the diode D1 and the diode D2 can be selected to be 2CL71A, and can also be other models meeting the requirements, and the models of the diode D1 and the diode D2 are not limited herein. The protection circuit principle is as follows: the resistance value of the resistor R3 was set to 20 megohms. According to ohm's law V/R ═ I, a 20 mega ohm resistor is connected in series with 3600V, and the current flowing through the resistor is less than 2MA and less than the safety range of 5MA for human body electric shock.
The negative ion generation principle is as follows: the direct current negative high voltage is connected to a release tip made of metal or carbon elements, high corona is generated by the tip direct current high voltage, a large amount of electrons (e-) are emitted at high speed, the electrons cannot exist in the air for a long time (the existing electrons have the service life of nS grade), and the electrons are immediately captured by oxygen molecules (O2) in the air, so that air negative ions are generated.
Wherein, exchange anion generating circuit includes: one end of a live wire L is connected with one end of a variable resistor R2, the other end of the variable resistor R2 is connected with one end of a thermistor RT, the other end of the thermistor RT is respectively connected with one end of a resistor R3, one end of a capacitor C1 and a pin 3 of a thyristor Q2, a transformer T1 is provided with an N1 winding and an N2 winding, the other end of the resistor R3 is respectively connected with one end of an N2 winding and one end of the capacitor C5, the other end of the capacitor C1 is connected with one end of the N1 winding, the other end of the N1 winding is connected with a pin 1 of the thyristor Q2, the other end of the N2 winding is connected with a negative electrode of a diode D1, the other end of the capacitor C5 is respectively connected with an anode of a diode D1 and one end of a resistor R4, a zero line N is connected with one end of the resistor R1, the other end of the resistor R1 is connected with a pin 2 of the thyristor Q2, and the other end of the resistor R4 outputs high voltage.
In the alternating current negative ion generating circuit, an oscillating circuit comprises a transformer T1, a thyristor triode Q2 and a capacitor C1, a rectifying circuit comprises a capacitor C5 and a diode D1, and a protection circuit comprises an R4 resistor. The working principle of the oscillating circuit is as follows: when the alternating current source is switched on, pins 1 and 2 of the thyristor Q2 are conducted in the positive half cycle. Current flows through the N1 winding of transformer T1 to charge capacitor C1. When the alternating current becomes negative half cycle, pins 1 and 3 of the triac Q2 are turned on and pins 1 and 2 are turned off. The current discharges to the capacitor C1 through the N1 winding of the transformer T1, and the positive half cycle and the negative half cycle of the alternating current are automatically switched to be jointed with the on-off matching of the thyristor Q2 to form oscillation. The number of turns of the N2 winding of transformer T1 was set to be about 35 times that of N1, so a pulse voltage of about 3600V was generated across the N3 winding of transformer T1. The direct current voltage of about 3600 is output after being rectified by a diode D1 and a capacitor C5, and the principle of the protection circuit is realized. The resistance of the resistor of the protection resistor R4 was set to 20 megohms. According to ohm's law V/R ═ I, a 20 mega ohm resistor is connected in series with 3600V, and the current flowing through the resistor is less than 2MA and less than the safety range of 5MA for human body electric shock.
The power supply of the negative ion generating circuit is a 12V direct current power supply, the output voltage of the negative ion generating circuit is-3.5V +/-1 KV direct current voltage, and the working current of the negative ion generating circuit is 10-50 mA.
In the anion generating circuit, the principle that the output voltage is reduced after the temperature is increased is as follows: when the anion generating circuit just begins to work, electronic components are in an initial value stage, and because the circuit during operation, electronic components have certain loss, this part loss can become the heat, slowly piles up on electronic components, and along with the time, thermal pile up, electronic components temperature can rise, and along with the rising of temperature, each item parameter of electronic components can descend, influences electronic components's performance, and the decline of electronic components parameter directly leads to the decline of anion generating circuit output voltage.
The thermistor RT is a negative temperature coefficient resistor. The thermistor is mainly characterized in that: the sensitivity is high, the resistance temperature coefficient of the sensor is more than 10-100 times larger than that of metal, and the temperature change of 10-6 ℃ can be detected; the working temperature range is wide, the normal temperature device is suitable for minus 55 ℃ to 315 ℃, the high temperature device is suitable for being higher than 315 ℃ (the highest temperature can reach 2000 ℃) and the low temperature device is suitable for being at minus 273 ℃ to minus 55 ℃; the volume is small, and the temperature of gaps, cavities and blood vessels in a living body which cannot be measured by other thermometers can be measured; the use is convenient, and the resistance value can be randomly selected from 0.1k omega to 100k omega; the product is easy to be processed into a complex shape and can be produced in large batch; good stability and strong overload capacity. The problem of output voltage drop can be solved by using the negative temperature coefficient of the thermistor RT.
The temperature compensation principle is as follows: when the negative ion generating circuit starts to work, the electronic components are in an initial value state, and the electronic components have certain loss when the circuit works, so that the loss becomes heat and is slowly accumulated on the components. As the temperature increases, the resistance of the thermistor will follow the temperature drop, and the drop in resistance will increase the current in the circuit. The increase in current increases the power of the module and the output voltage increases with the increase in power. The stabilization of the output voltage is achieved.
In the embodiment, after the secondary of the transformer outputs the pulse high voltage, the pulse high voltage is rectified into the direct current high voltage through the diode and filtered by the capacitor, the thermistor is connected in series with the current limiting resistor of the input circuit, and the resistance value is reduced along with the rise of the temperature when the temperature rises, so that the temperature compensation purpose of the anion generator is achieved, the output voltage is stable, and the anion concentration achieves the expected effect.
