Abstract

(57) [Summary] [Purpose] To ensure the miniaturization and safety of hair curlers. [Structure] By incorporating a battery in the hair curler, the hair curler can be made smaller and more convenient to carry than when a separate heater is used. Also, by providing a timer circuit in the cap to prevent over-discharge of the battery, the discharge of the battery will be cut off after a certain period of time, so it is possible to prevent heating of the hair curler, which is more safe. Can be secured.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a hair curler for a small device.

[0002]

[Prior Art]

 Conventionally, hair curlers have been used by heating the curler part with an alternating current method. However, this method has a problem that the shape of the heating section becomes large and a large amount of space is required for the heating section, and there is a risk that the heating section may cause burns due to this heating section. .

Therefore, in JP-B-55-13723, JP-B-55-13724, and JP-B-57-4321, a hair curler in which a battery and a heater are housed in a cylinder, and the battery heats the heater, A charging terminal is provided on one end of the battery, and a hair curler that heats the heater during charging and a series circuit of a heater and a switch that controls the energization of the heater are connected in parallel to the storage battery. We are proposing a hair curler that can connect a parallel circuit to a charger.

[0004]

[Problems to be solved by the device]

 However, Japanese Patent Publication No. 55-13724 and Japanese Patent Publication No. 57-4321 described above require a charging circuit to be housed in the hair curler in order to directly charge the storage battery itself in the hair curler. It's difficult to be a hair curler. In Japanese Patent Publication No. 55-13723, the temperature control element is used to maintain the specified temperature, so that the surface temperature of the hair curler is kept constant, but if the hair curler sleeps, , It is dangerous to keep the hair curler heated to the specified temperature until the capacity of the battery itself is exhausted.

Therefore, in order to solve the above problems, the present invention uses a timer circuit so that the battery is not over-discharged and cuts off the discharge of the battery after a certain period of time. For this reason, even if the hair curler is used, the battery will be discharged after a certain period of time, which is safe.

[0006]

[Means for Solving the Problems]

 The present invention is directed to a battery, a cap provided with a circuit having a timer function that prevents the battery from being over-discharged, a positive temperature coefficient thermistor that serves as a heater, and a heat conducting unit that transfers the heat generated by the thermistor to the entire inner surface of the hair curler. And more.

[0007]

[Action]

 A battery and a positive temperature coefficient thermistor are installed inside the hair curler, which heats the hair curler itself, so the hair curler itself can be made smaller than when a separate heater is used, and it is convenient to carry. In addition, a circuit with a timer function to prevent over-discharge of the battery is provided in the cap of the hair curler, which enables miniaturization and automatically stops the heating of the hair curler after a certain period of time.

【Example】

 Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

Reference numeral 1 denotes a body case of the hair curler according to the present invention. A large number of protrusions 10 are provided on the outer periphery of the body case 1. A positive temperature coefficient thermistor 9 is disposed on the inner bottom surface of the main body case 1, and the positive electrode terminal 6 and the negative electrode terminal 7 are connected to the positive temperature coefficient thermistor 9. The insulating plate 5 is arranged on the upper surface of the positive temperature coefficient thermistor 9. Reference numeral 4 denotes a dry battery or a secondary battery, the outer peripheral surface of which is covered with an insulating case 3. The positive electrode portion of the battery 4 is in contact with the substantially U-shaped portion of the positive electrode terminal 6 via the insulating plate 5. By disposing the heat conducting portion 2 on the inner peripheral surface of the body case 1, the heat generated by the positive temperature coefficient thermistor 9 in contact with the heat conducting portion 2 is conducted to the entire body case to warm the hair curlers. The battery 4 can be attached and detached by inserting and removing the cap 8 on the upper portion of the main body case 1. On the side surface of the cap 8, terminals that engage with the positive electrode terminal 6 and the negative electrode terminal 7 are formed, respectively. When the cap 8 is attached to the main body case 1, the terminals come into contact with each other, and a current flows through the positive temperature coefficient thermistor 9. Further, since the timer circuit shown in FIG. 4 is incorporated in the cap 8, the timer circuit terminates the discharge of the battery after a lapse of a predetermined time. Therefore, there is no danger if you fall asleep while wearing a hair curler.

[0010]

[Effect of the device]

 The hair curler according to the present invention has a built-in battery in the hair curler, so it is smaller and more convenient to carry than when a separate heater is used. In addition, by installing the timer circuit inside the hair curler, it is possible to prevent the hair curler from overheating due to over-discharge of the battery, and the safety is improved.
