Description

Negative ion operating device

The present invention relates to an anion generator, and more particularly, to generate pure anions of ozone (O3) and nox (NOx) through the generation of negative ions using only the negative electrode. It is invented to maintain a comfortable indoor environment at all times.

Generally, clean air in the forest is rich in negatively charged negative ions, and on the contrary, there is a large amount of positively charged cations in the exhaust emissions from vehicles and factories.

In addition, inhalation of a large number of negative ions in the human body has been reported that the body function is activated by reducing the oxidized body function has already been studied in the academic world.

In addition, in recent years, due to the rapid industrial development, air pollution has reached a serious state, and as a result, more cations are emitted, which necessitates the formation and neutralization of negative ions, thereby neutralizing the cations contained in the indoor air. Many negative ion generators for generating negative ions have been developed and used indoors.

However, most conventional anion generators are configured to simply generate an anion locally by corona discharge or plasma discharge by supplying a high pressure through an anion generating needle, so that local anions are generated when used for a long time, such as ozone and nitrogen oxides. There is a problem that can cause a lot of damage to the health of the human body as the harmful substances are generated, and the head is sick and nauseous and the chest becomes stuffy with a scent.

The present invention has been made to solve the above-mentioned conventional problems, by driving the fan with the generation of negative ions to allow the negative ions to be widely spread in the room through the Brown movement and fan blowing function and at the same time using only negative ions By generating pure anions of ozone (O3) and nox (NOx), the polluted indoor air can be changed to clean and refreshing air like the air in the forest. Of course, the purpose is to provide an anion generator that can promote the metabolism of the human body.

An object of the present invention as described above, the power supply for supplying a DC voltage required for the operation of the device; A reverse voltage supply preventing unit for preventing an internal circuit from being burned out due to a wrong power supply; A power on / off switch unit for controlling supply of a power voltage supplied to each unit; An oscillation unit which oscillates when the DC voltage is supplied from the power supply unit through the power on / off switch unit and converts the oscillation into an AC voltage having a predetermined frequency; A booster for boosting an AC voltage of a predetermined frequency output from the oscillator to an AC voltage necessary for driving a discharge unit; A discharge unit for discharging the high voltage supplied from the boosting unit into air to generate a negative potential through insulation breakdown of the air; A fan driver for driving a fan to distribute the negative potential generated by the discharge unit to a far distance in a room when the output voltage of the power supply unit is supplied through a power on / off switch unit; When the fan and the discharge unit are driven, the green LED is driven, and when only a high voltage is generated, the operation state display unit drives the red LED.

Therefore, the anion is spread evenly throughout the room by its own Brown movement and fan blowing operation, which can change the contaminated indoor air into clean and fresh air in a wide range, so that it can always maintain a comfortable indoor air environment. Therefore, it is possible to promote the metabolism of the human body.

According to the present invention, the negative ion generator includes a power supply unit 1 having a power connection plug connected to an external rectifier and supplying a DC voltage necessary for the operation of the device, and a reverse voltage preventing diode D1. To prevent the internal circuit from being burned out by the reverse voltage when the user reverses the power supply terminal (+ .-) of the rectifier connected to the power supply unit 1 to prevent the internal circuit from being burned out by the reverse voltage (2). And a three-row switch (SW1) and two noise filter capacitors (C1, C2) so that the user can selectively output the output voltage of the power supply unit (1) to the oscillator (4) and the fan driver (7). Power on / off switch section 3 for simultaneous supply, two reverse voltage protection diodes D2 and D3, several capacitors C3-C5, resistors R1-R3 and switching transistors Q1. Consists of the power on / off switch When the DC voltage is supplied from the power supply unit 1 through the unit 3, the oscillation operation 4 converts it into an AC voltage having a predetermined frequency (about 25 KHz), a boost transformer T1, and a resistor ( R4), several high voltage diodes (D4-D7) and high voltage capacitors (C6-C9), the AC voltage of a constant frequency output from the oscillator (4) is required to drive a high voltage AC voltage for driving the discharge part (6). It consists of a boosting unit 5 for boosting the pressure, a current limiting resistor R5 and a high voltage wire (HV W) to discharge negative high voltage supplied from the boosting unit 5 into the air to prevent breakdown of air. And a discharge part 6 for generating a negative potential through the resistor, a resistor R6, a diode D8, and a capacitor C10. The output voltage of the power supply 1 causes the power on / off switch part 3 to When supplied through the fan (FAN) to drive the negative potential generated by the discharge unit 6 far away in the room It is composed of a fan driver 7 which is widely distributed up to and several resistors R7-R10 and green and red light emitting diodes LED1 and LED2. When the light emitting diode LED1 is driven and only the discharge unit 7 is driven, the operation state display unit 8 drives the red light emitting diode LED2.

Referring to the effect of the anion generator of the present invention configured as described above are as follows.

First, a rectifier (not shown) is used to selectively connect the power supply plug PLUG of the power supply unit 1 to the respective parts of the apparatus of the present invention. Make sure to supply it.

At this time, the power supply voltage is supplied to each part only when the power connection plug (PLUG) of the power supply unit 1 and the power supply polarity (+,-) of the rectifier are correctly connected to each other. In the case of reverse connection of,-), a reverse voltage is supplied to each part of the apparatus of the present invention, which may lead to a fire when the internal circuit is damaged or severe.

Therefore, in the present invention, the user inadvertently turns on the power supply by providing a soft voltage supply prevention unit 2 including the reverse voltage prevention diode D1 between the power supply unit 1 and the power on / off switch unit 2. Even if the power supply terminal (+ .-) of the rectifier connected to the supply unit 1 is reversely connected, the power supply to the internal circuit can be cut off to prevent the internal circuit from being burned out and the occurrence of fire.

In addition, the power on / off switch section 3 is provided with a three-row switch SW1 to select " off " to stop the operation of all functions, and supply voltage to the oscillation section 4 and the fan drive section 4 simultaneously. It is possible to select any one of the functions to select the operation of the full function and the operation of the fan and to operate only the circuit part after the oscillation part 4 so that only negative ions are generated.

At this time, the capacitors C1 and C2 filter out noise generated when the three-row switch SW1 is operated to prevent the internal circuits from being malfunctioned or burned out by this noise.

On the other hand, the oscillator 4 is oscillated when the DC voltage is supplied from the power supply unit 1 through the power on / off switch unit 3 to convert it into an AC voltage of a predetermined frequency (about 25KHz) required for boosting do.

At this time, the reverse voltage prevention diode D2 in the oscillation section 4 is in the mode in which the switch SW1 is in the simultaneous driving mode of the discharge section 6 and the fan FAN and only the discharge section 6 is driven. When present, the voltage applied to the high voltage module unit is the same, and the reverse voltage preventing diode D3 serves to block the driving of the fan and to prevent the supply of the power supply voltage to the fan driving unit 7 when in the negative ion generating mode.

In addition, the resistor R1 limits the current flowing to the oscillator 4, the capacitor C3 removes noise included in the power supply voltage as an electrolytic capacitor, and the two resistors R2 and R3 are connected to the transistor Q1. The capacitor C4 serves to adjust the base bias voltage, and the capacitor C4 determines the time constant of the resistor R1 and the oscillation frequency. The capacitor C5 performs the heavy electric power according to the oscillation frequency of the oscillator 4. And it determines the amplitude of the discharge.

Of course, the transistor Q1 is switched in response to the time constant to perform a function of supplying an AC voltage of a predetermined frequency to the booster 5.

On the other hand, the booster 5 boosts the AC voltage of a predetermined frequency output from the oscillator 4 to a high voltage AC voltage required for driving the discharge unit 6, and boosts the booster 5 in the booster 5. The transformer T1 is manufactured to have a winding ratio of 12: 1200 so that an output voltage of about 1.2KV is induced when an AC voltage of about 12V is input.

At this time, since the boosting unit 5 has an atmospheric discharge type, it is possible to increase the discharge efficiency during atmospheric discharge by using the virtual grounding resistor R4.

In addition, the high voltage output from the boosting transformer T1 is boosted to multiple stages (four stages in the drawing) through several high voltage diodes D4-D7 and high voltage capacitors C6-C9. The final output can be boosted from about 6KV to 7.5KV by stepping up by KV.

The booster 5 used in the negative ion generator of the present invention is a negative booster circuit for obtaining a negative voltage, and the final output is a negative voltage (-) of a high voltage. In general, the insulation resistance of the air (air) using a high voltage is used. Since the voltage to break is about 4KV, in the present invention, a high voltage of about -6KV is generated in the discharge part 6, and the higher the voltage, the better the insulation of air can be destroyed.

As such, the negative high voltage (about -6 KV) output from the boosting unit 5 is discharged to the atmosphere through the high voltage wire HV W in the discharge unit 6 to generate a large amount of negative ions through insulation breakdown of the air. .

That is, in the discharge part 6 of the present invention, unlike the conventional corona discharge or plasma discharge, the discharge of the high voltage of about -6KV through the high voltage wire (HV W), which is a cathode, prevents the generation of harmful substances such as ozone. It can be.

In this case, the high-voltage wire (HV W) is a natural nanomaterial is decomposed into nanoparticles and then deposited on steel fiber by the advanced nano-coating technique, generally using only steel to discharge high voltage in the atmosphere and carbon fiber In comparison with the case of discharging the fixed pressure in the air, the results show that the natural minerals emit about 100 times anion when using only steel and about 10 times when using carbon fiber. In particular, it can be seen that in the case of steel and carbon fiber, only pure anions are emitted without generating ozone and nitrogen oxides.

On the other hand, the resistor R5 installed in the boosting unit 6 has a resistance value of about 22 ohms so as to limit the current as much as possible at the time of high voltage output, so as not to harm the human body when an electrical breakdown such as electric shock or short circuit occurs. At the same time, it plays a role of preventing a fire from occurring.

In addition, when only high pressure is generated in the air, negative ions are present only within the resistance breakdown range of air, and such anions may be spread by moving to a certain distance by the Brownian movement, but the range is extremely narrow.

Therefore, in the fan drive unit 7 installed in the apparatus of the present invention, when the output voltage of the power supply unit 1 is supplied through the power on / off switch unit 3, the fan FAN is driven by the discharge unit 6. The generated negative potential can be distributed to a far distance in the room

The negative ions generated by the insulation breakdown of the air due to the negative high voltage generated in the discharge part 6 are spread evenly throughout the room by its Brown movement and fan blowing operation (that is, the use range is It can convert contaminated indoor air into clean and fresh air in a wide range.

However, it is known that the anion generally retains its electron for about 60 seconds.

At this time, the resistor R6 in the fan driver 7 applies “0” ohms in the present invention for limiting the input current of the fan FAN, and the diode D8 is applied when the initial power is applied to the fan FAN. It serves to block the generated counter electromotive force, and the capacitor (C10) as the electrolytic capacitor serves to remove the noise that may occur when the initial power is applied to the fan (FAN).

On the other hand, the operation state display unit 8 composed of several resistors R7-R10 and green and red light emitting diodes (LED1, LED2) performs a function that the user can visually check the generation of negative ions and the driving state of the fan. In the present invention, the green light emitting diode LED1 is turned on when the fan FAN and the discharge portion 7 are driven at the same time, and the red light emitting diode is driven when only the discharge portion 7 is driven without the fan FAM. (LED2) was turned on.

In this case, the resistors R7 to R10 in the operation state display unit 8 limit the voltage supplied to the light emitting diodes to about 2.5 V for current limiting and voltage regulation of the green and red light emitting diodes LED1 and LED2. It is designed to manufacture below 5mA.

As described above, according to the present invention, the fan is driven together with the generation of negative ions, and thus, the negative electrode, unlike the conventional corona discharge or plasma discharge, can be spread widely in the room by the brown movement of the negative ions and the fan blowing operation. By generating negative ions by discharging negative high voltage in the air through only high voltage wires, it is possible to generate pure anions of ozone (O3) and nox (NOx). It can be changed to fresh and fresh air.

Therefore, it is a very useful invention that can maintain a comfortable indoor environment at all times, thereby promoting metabolism of the human body.
