Hair care is performed by generating negative ions and ozone from an ion electrode and an ozone electrode provided on the side winding, respectively.

The operation of the hair dryer will be described. First, when 100 V AC is input to the input terminal,
It is purified by a diode and converted to direct current. Furthermore, the voltage converted into DC is applied to a series resonance circuit composed of a capacitor and a primary winding of a transformer, and charging and discharging of the capacitor and turning on of the thyristor are repeated. A relatively high frequency alternating current is applied to the primary winding of the transformer according to the timing of the transformer, and as a result, a high voltage is output so that ions can be generated at the terminal of the secondary winding of the transformer. ing.

Reference numeral 12 denotes a transformer, which is disposed near the upper center of the housing 1a and connected to a circuit in the housing 1a by an ion generator lead wire 11. The transformer 12 includes an electronic component 13 therein. The transformer 12 is connected to a negative ionization needle 15 provided substantially at the center near the distal end of the discharge port 17 of the cylindrical portion 9 via an ionization lead wire 19 to thereby generate a negative ion generator 8. Is composed.

The negative ionization needle 15 is a special alloy made of chromium, nickel, and steel, and is polished extremely finely in the forming step, and further polished so that the tip of the needle becomes thinner. Negative ions are emitted from the tip of this extremely fine and sharp needle.

The electronic component 13 in the transformer 12 includes a transformer 20, a capacitor 21, a resistor 22, and the like, and applies a primary voltage of 100V (volt) to a secondary voltage of 15V by electronic control as shown in FIG. Then, the secondary voltage is increased stepwise so that a high voltage of 3700 V is generated at the negative ionization needle 15. At this time, between the primary voltage (100 V net voltage) and the secondary voltage (15 V), which are line voltages, the voltage is applied by galvanic separation, and there is no metallic connection, so that conduction may occur. Not safe.

Here, a change in voltage by the transformer 12 will be described with reference to FIG. In the transformer 12, when an AC voltage of 100V is first input to the primary transformer, a voltage of 15V AC is generated in the secondary transformer.

Next, this voltage is converted into a 15 V unsmoothed DC by a rectifier (not shown), and further applied to the primary winding in the negative ion generator 8.

Since the air is converged and discharged in a regulated state, the negative ions can be discharged effectively.

At the time of use, the negative ions protect the cuticle, which is a component of the hair arranged substantially in a scale on the hair, and combine the negative ions with the water present in the air or the water contained in the hair. By adjusting the molecular arrangement of the hair, the cuticle can be arranged at the molecular level, and the spread of the scale-like cuticle can be prevented to smooth the hair.

Further, the molecular mass of water ionized by negative ions becomes ultra-fine particles and penetrates into the inside of the hair cells, so that the hair can be glossy and leave a moderate moisturizing feeling. Even if the hair is blown, it is possible to prevent the hair from losing moisture and becoming in a state of dryness. Further, since the hair can be protected in this manner, it is possible to make it difficult for the hair to be stained with oil and dust.
