Most molecules in the air that humans breathe are basically neutral, but are ionized by energy from radiation, ultraviolet rays, cosmic rays, and heat, forming ionic states. The ratio of cation and anion is constant at the level where clean air is stable, but in air pollution and enclosed space, the ionic composition ratio of steady state is destroyed by various harmful environments, and the cation is predominantly changed. By making it a lump of particles, it interferes with the body's blood purification, cell activation, resistance, and autonomic nerve regulation.

Therefore, various devices for artificially releasing anions have been proposed, and in the present invention, an anion releasing voltage distribution circuit is separately configured to release anions into the air through a hair brush.

The principle of negative ion generation according to the present invention is as follows.

As shown in FIGS. 1A and 1B, a case in which a calmed molecule is supplied with electrons for some reason to be energized is said to be anionized. Oxygen and chlorine have such properties. Anion generators are devices that emit large amounts of electrons and ionize surrounding materials. Often, a high voltage method is used. In the high voltage method, when a negative voltage is applied using a voltage of thousands of volts, the insulation of air is destroyed by a high energy process by a high energy process, and the discharge current rapidly increases. It has enough energy to cause it to be released into the air at high speed. In particular, as shown in FIGS. 2A and 2B, the sharper the cathode, the greater the amount of electrons emitted, and the released electrons combine with oxygen molecules to generate anionized oxygen, which is used to remove harmful electromagnetic waves, air purification, dust and bacteria. Has the action of elimination.

The UV LED is a next-generation product that can be used for air purification, energy saving, and resource energy preservation using short wavelengths, unlike conventional LEDs mainly used as display devices. In particular, the UV LED is a conventional method of coating blue LEDs with phosphors to make white LEDs. Could not produce natural light, but it is expected to create a huge new market in the future as it can produce perfect natural light by using ultraviolet LED.

Hereinafter, an external diagram and an internal circuit diagram of an embodiment of a hair brush having ultraviolet LEDs and anion generators according to the present invention will be described in detail.

As shown in FIG. 3, the hair brush incorporating the ultraviolet LED and the negative ion generator according to the present invention includes a brush 2 for trimming hair, an operation switch 12, 14, 16, and an operation lamp 11, 17. In the hair brush consisting of a handle (6) integrally formed with the main body (1) so that the user can hold and use in the hand, the brush (2) for grooming the hair is supported so as not to escape to the outside A plurality of covers 3 are provided at a predetermined portion of one side of the cover 3 to prevent foreign substances from penetrating through the formed negative ion outlet 4, and have a wavelength of 397 to 10 nm at several wavelengths. It is provided on the side of the holder 18 and the cradle 18 for charging the power supply device provided on the inside of the handle 6 at the same time while mounting the ultraviolet light (5) and the handle (6) And keep the comb and so on And a power supply circuit for controlling a power supply and a control operation by generating a predetermined control signal according to the operation of the switches 12, 14, and 16, provided in the storage box 19 and the main body 1.

The negative ion outlet 4 is an embodiment of the present invention, and has a long oval structure in the downward direction, is blocked by a cover 3 to prevent foreign matter from penetrating from the outside, the cover 3 is a fine fabric Since the structure does not penetrate the foreign matter such as dust and hair to the inside, the anion released from the negative ion generator 24 according to the present invention can be freely released to the outside.

In addition, a predetermined portion of the handle 6 is provided with a rechargeable battery (not shown). The rechargeable battery is charged and used by a charging device (not shown) provided inside the holder 18. When the user cleans the hair with the hair brush, when the brush switch 12 provided at one side of the handle 6 is pressed, the power display lamp 11 is turned on for a predetermined time and the negative ion outlet ( Anion is released through 4), ultraviolet LED (5) is lit to perform a sterilization action.

The method of charging the rechargeable battery in a state in which the rechargeable battery is inserted into the holder 18 is a well-known technique generally used in a conventional charging device, and thus detailed description thereof will be omitted.

In addition, when the user presses the air purifying switch 14 in the state in which the hair brush is inserted into the holder 18, the power indicator lamp 11 lights up to indicate that the hair brush is in use, and the negative ion for a predetermined time is set. Anion is discharged through the discharge port 4, the ultraviolet LED 5 is turned on to perform sterilization and at the same time, the rechargeable battery is charged through the charging device of the holder 18.

Hereinafter, as an embodiment of a hair brush incorporating an ultraviolet LED and an anion generator according to the present invention, an anion emission double voltage circuit, a power supply circuit and a control circuit, and an ultraviolet LED circuit will be described in detail.

As shown in FIG. 4, the power supply circuit and the control circuit block the bridge diode 10 which prevents damage to the circuit according to the polarity of the DC power supply, and cuts off the power transmitted through the bridge diode 10. Air purge switch S2 14 which supplies power to the hair brush for a predetermined time corresponding to the discharge time of capacitance C7, and when the hair brush is in the charging state by being inserted into the holder 18, the transistor Q1 is driven. Connection display lamp L1 (17) which lights up, brush switch S1 (12) which operates a hair brush using the power supply of the battery provided in the inside of the said main body 1, and said air purification switch S2 (14) or brush When the switch S1 (12) is turned on, the power display lamp L2 (11) which is turned on by the driving of the transistor Q2 and the timer IC 21, and the off to cut off the power of the hair brush It consists of a position S3 (16), and a capacitance C6 and resistors R8, R9 and the timer IC unit 20 to reduce the consumption current consumed by the hair brush by adjusting the oscillation frequency by the diode D5.

The bridge diode 10 is to prevent damage to the power circuit when the AC power is changed to a DC power through an adapter (not shown) and the polarity thereof is incorrectly connected. It is connected to the bridge diode (10).

The DC power delivered through the bridge diode 10 operates the transistor Q1 when the user operates the air purification switch S2 (14), operates the connection display lamp L1 (17), and simultaneously operates the transistor Q2 to operate the timer. Power is supplied to the IC unit 20.

In the timer IC 21, the oscillation frequency is controlled by the capacitance C6, the resistors R8, R9, and the diode D5 to reduce the current consumption of the hair brush, and at the same time supply power to the negative ion emission voltage distribution circuit and the ultraviolet LED circuit. Power supply indicator L2 (11) is turned on.

The IC 555 operates at 5V or more and can realize a time of about 10 seconds at 10 s. By using an analog method of setting the timer time by the time constant, the long time timer can be realized by using a good capacitance.

Meanwhile, in the present invention, the IC 555 forms the timer IC unit 20 as shown in FIG. 4, and the timer IC unit 20 is used for the purpose of reducing power consumption by configuring an oscillation circuit. The principle is as follows.

Since the voltage on capacitor C6 is applied to pin 2, the trigger is effective when the power supply voltage is lower than 1/3 of the power supply voltage. Therefore, when the voltage on C6 is low, the timer starts.

C6 is also connected to pin 6, which has a function to stop the timer when the voltage of C6 exceeds 2/3 of the power supply voltage. During the start of the timer, C6 charges C6 through R8 and R9. It becomes high (H). The voltage at C6 is discharged through R9 because the pin 7 becomes 0 V while the timer is stopped.

As a result, when the voltage of C6 is less than 1/3 of the power supply voltage, the timer starts and the operation of stopping when 2/3 or more is permanently repeated to constitute the oscillation circuit.

After being amplified by a high voltage DC voltage, it is applied to the anode (+) of the negative ion generator 24.

Therefore, a gas discharge is generated by applying a very high high voltage between two electrodes consisting of the positive electrode (+) and the negative electrode (−) of the negative ion generator 24, and when the gas discharge occurs, negative ions are generated by the discharge phenomenon. do.

On the other hand, the negative ion generator 24 is formed in a structure in which the negative ions are released through the space of the center portion by bringing a sharp needle-like cathode (-) electrode close to the center of the circular positive electrode (+) electrode as shown in FIG. Therefore, the discharge strength of the negative ions through the central portion is enhanced.

In addition, the ultraviolet LED circuit according to the present invention, as shown in Figure 8, the plurality of ultraviolet LED (5) is connected in parallel to simultaneously turn on by the power delivered through the power supply circuit and the control circuit, sterilization action Will be performed.

4, 5 and 6 is an embodiment of the present invention, the circuit does not limit the scope of the present invention.
