Description

[Detailed description of the invention] [Industrial application field] This invention relates to a rechargeable hair iron in which a hair curling bar is foldable with respect to a grip tube, and the hair curling iron is folded in a stable position. It can only be charged at

[Conventional technology]

2. Description of the Related Art Conventionally, there has been a hair iron in which a hair curling bar is foldably and pivotally connected to a grip tube, making it convenient to carry and store.

[Problem that the invention attempts to solve]

The problem here is that if a rechargeable type is used as the power supply means for the above-mentioned foldable hair iron, the hair curling bar will be in a substantially straight line with the grip tube as the position of the hair iron during charging. It is a matter of whether charging is performed under the usage position or whether it is performed under the folded position. When the hair iron is used in the above-mentioned position, its total length becomes longer, so the charging plug outlet (especially the outlet embedded in a vertical wall)
The insertion state tends to be unstable, but
In its folded position, it can be shortened to approximately half its length, allowing the charging plug to remain stably and securely inserted into the outlet. Therefore, it can be said that it is preferable to charge the battery in the folded position.

However, for example, if the instruction manual simply describes such a preferable charging operation method, it is not certain that the user will necessarily perform the charging operation in accordance with the instruction manual.

This invention focuses on this fact and aims to force the user to perform a preferable charging operation while in a stable position by devising a device that prevents the hair iron from being charged unless it is folded. .

[Means for solving problems]

In order to achieve the above purpose, the present invention
As shown in the figure, a hair wrapping bar is pivotally connected to a gripping tube 1 in a usage position in which it is in a substantially straight line in front of the gripping tube 1 and in a posture in which it is folded approximately parallel to the gripping tube 1. 2, a rechargeable battery 7 that supplies power to the heater 6 attached to the hair curling bar 2, and a battery 7.
A rechargeable hair iron is assumed to be provided with a charging circuit 8 that can be charged, and a charging plug 10 that connects a commercial AC power source and the charging circuit 8.

Furthermore, a switch 11 is provided between the opposing surfaces of the hair wrapping bar 2 and the grip tube 1, which are opposed to each other by folding the hair wrapping bar 2, to connect the charging plug 10 to the charging circuit 8.

[Effect]

In such a case, when the hair wrapping bar 2 is folded, the switch 11 is turned on, and charging is enabled for the first time. In other words, the hair wrapping bar 2 cannot be charged unless it is folded.

[Effect of idea]

As explained above, according to the present invention, since the hair curling bar 2 cannot be charged unless it is folded, it is possible to avoid the user from charging the hair iron while using the hair iron in an unstable position. Therefore, it is possible to actively promote and develop a preferable charging operation in a stable folded position.

〔Example〕

Hereinafter, embodiments of the rechargeable hair iron according to the present invention will be described based on the drawings. This hair iron consists of a grip tube 1 and a hair curling bar 2, and the hair curling bar 2 is in a usage position in which it is substantially in a straight line in front of the grip tube 1 (phantom line state diagram in Fig. 1).
and a folded position facing substantially parallel to the ventral side of the gripping tube 1 (shown by the solid line in FIG. 1). On the circumferential surface of the hair winding bar 2, brushes 5 and heaters 6 are arranged and fixed alternately in the circumferential direction. Also, a cap 12 is attached to the tip of the hair curling bar 2.
Install. This cap 12 is used to make it easier to rotate the hair wrapping bar 2 around the pin 4 by pinching it with your fingers.

The inside of the grip tube 1 is provided with a rechargeable battery 7 as a power source for the heater 6, and a charging circuit 8 for charging the battery 7, and a slide type switch knob 9 is provided on a part of the side surface of the grip tube 1.

The rechargeable battery 7 is connected to one end of the heater 6 and the other end of the heater 6 via a switch 13 as shown in FIG. The power to 6 is disconnected.

The charging circuit 8 steps down the commercial AC voltage that is input from the charging plug 10 that is removably attached to the rear end of the back side of the grip tube 1 to a predetermined charging voltage, and converts the charging voltage output from the charging circuit 8 into a battery. 7 to charge the battery. At this time, a switch 11 for connecting the charging plug 10 to the charging circuit 8 connects, for example, the cap 12 between the opposing surfaces of the hair wrapping bar 2 and the gripping cylinder 1, which face each other when the hair wrapping bar 2 is folded. It is provided between a surface facing a part of the circumferential surface of the grip cylinder 1 that the cap 12 comes into contact with. Therefore, the charging can only be performed by folding the hair wrapping bar 2 and turning on the switch 11, and charging cannot be performed when the hair wrapping bar 2 is in a position of use in a substantially straight line with respect to the grip tube 1. .

It goes without saying that the hair iron of the present invention can be similarly applied to those in which the hair curling bar 2 does not include the brush 5.
