Description

DETAILED DESCRIPTION OF THE INVENTION (Technical Field) The present invention relates to a hair curler for setting hair.

(Background Art) As shown in Fig. 1, in a hair dryer with an attachment 1 attached to the tip, when hair is wrapped around the attachment 1, the hot air outlet 1c is blocked by the hair, so the hot air is There is a problem that it tends to get crowded and the temperature gets high, which can easily damage your hair.

(Object of the Invention) The present invention has been proposed in view of the above points, and its purpose is to provide a method for controlling air temperature by attaching a sensor for controlling air temperature to an attachment for curling hair, that is, a hair curling member. To provide a hair curler capable of detecting the temperature of hair and controlling the temperature acting on the hair at a constant level.

(Structure of the invention) The present invention will be described below with reference to the drawings.

Figure 1A shows a removable hair curler according to the present invention, that is, an attachment 1 for curling hair.
This figure shows the case where the hair dryer body 2 is attached to the hair dryer body 2. As is well known, inside the hair dryer body 2 there is a hot air generating device (made up of a heater, a group of circuit parts, a motor, a fan, etc.) from the right end to the left end. (not shown) is provided.

Figure 2 shows a control circuit built into the hair dryer main body 2 and the attachment 1 for temperature control, etc. The present invention is characterized by the fact that the temperature sensor 3 consisting of a thermistor etc. and its terminal are provided on the attachment 1 side. have.

In the figure, 4 is an AC power supply, 5 is a switch,
6 is a rectifier block consisting of a diode bridge.
One end of the AC side input is connected to the AC power source 4 via the switch 5.
The other end is connected to the other end of the AC power source 4 via a voltage dividing resistor 7 and a noise prevention coil 8. Reference numeral 9 denotes a blower motor, which is connected to the DC output terminal of the rectifier block 6 via coils 10 and 11 for motor noise prevention. Note that a capacitor 12 for motor noise protection is inserted between these DC output terminals.

Note that a temperature sensor 3 such as a PTC thermistor that detects the ambient temperature is provided at a location where the ambient temperature can be quickly detected, that is, inside the attachment 1, and a variable resistor 13 and a variable resistor 13 are connected in series to the temperature sensor 3. A capacitor 14 is connected, and this first series circuit is connected to both ends of the AC power supply 4. Further, a heater 15 is inserted between the switch 5 and one end of the temperature sensor 3 such as a PTC thermistor. Further, a second series circuit consisting of a resistor 16 and a diode 17 is connected in parallel to the first series circuit.
A triac 18 is connected to the series circuit, and the control terminal of the triac 18 is connected to the variable resistor 13 and capacitor 14 of the first series circuit.
A diode 20 is inserted between the control terminal of the SBS trigger element 19 and the connection point of the resistor 16 and diode 17 of the second series circuit. Note that 21 is a capacitor for noise prevention.

However, when it comes to operation, I am currently using switch 5.
When the AC power source 4 is turned on, the AC power source 4 is rectified into DC by the rectifier block 6 and supplied to the motor 9, thereby driving the air blowing motor 9.

In this case, when the rotation speed of the motor 9 is constant, even if the discharge air volume changes due to hair being wrapped around the attachment 1, the temperature sensor 3 detects the air temperature, and the SBS trigger element 19 detects the air temperature. The air temperature is kept constant by controlling the power of the heater 15 by controlling the phase of the operating point.

Figures 2A and 2B show details of the attachment 1 according to the present invention to which the temperature sensor 3 is attached, where 1a is the attachment mounting part, and 1b is the cylindrical hair wrapping part provided at the tip thereof. It is made of metal or the like with good thermal conductivity, has a hot air outlet 1c formed at an appropriate position, and has a brush-shaped hair wrapping member 1d protruding therefrom.

Thus, a temperature sensor 3 is provided inside the hair wrapping part 1b, and the terminal of this temperature sensor 3 itself is connected to a chip-shaped printed circuit board 22 by soldering, and the printed circuit board 22 is connected to the hair wrapping section 1b by means of an adhesive. The temperature sensor 3 is attached to the inner circumferential wall of the attachment part 1b, so that the temperature sensor 3 is attached to the hair wrapping part 1 so as to accurately detect the temperature.
It is attached to the inner circumferential wall of the metal part in contact with b. Thus, a convex rib 1e is provided at the insertion opening of the attachment mounting portion 1a, and a metal piece 23 serving as a terminal of the temperature sensor 3 for electrical connection is adhered to the outer surface of the rib 1e. One end of a lead wire 24 is connected to the piece 23 by soldering 25, and the other end of the lead wire 24 is connected to the printed circuit board 22.

FIGS. 3A and 3B and FIGS. 4A and 4B show how the attachment 1 and the hair dryer main body 2 are attached. Cylindrical attachment part 2a of hair dryer main body 2
is formed to have a diameter that allows insertion of the attachment mounting portion 1a, and a pair of grooves 2b are formed in the mounting portion 2a to correspond to and receive the ribs 1e of the attachment mounting portion 1a. Also, groove 2
For example, extending portions 2c extending clockwise are formed at the bottoms of b, metal pieces 2b are provided on the extending portions 2c, and metal pieces 2b are provided within the hair dryer main body 2. A lead wire 27 connected to a predetermined circuit (see FIG. 1B) is connected.

In use, the attachment 1 is inserted into the attachment part 2a of the hair dryer main body 2. In this case, the rib 1e having the terminal of the temperature sensor 3 built into the attachment 1 is inserted into the groove 2b.
By inserting it into the groove and rotating it clockwise at the bottom of the groove to fit it into the extension part 2c, it is possible to mechanically connect the two and prevent the metal from coming off. The pieces 23 and 26 can be brought into contact with each other, and the temperature sensor 3 inside the attachment 1 and the circuit inside the hair dryer main body 2 can be electrically connected to obtain a desired circuit operation.

(Effects of the Invention) As described above, according to the present invention, there is provided an attachment that is detachable from a hair dryer body equipped with a hot air generating device composed of a heater, a motor, a fan, etc., and that the attachment is capable of detecting temperature. Since the structure includes a temperature sensor and its terminal, you can wrap the hair around the attachment,
Even when the temperature becomes high, the temperature acting on the hair can be quickly detected by the temperature sensor provided in the attachment, and the temperature can be controlled to a suitable temperature.
