Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a gas combustion heating type igniter for hair curlers.

Conventional Structures and Problems Conventionally, most hair curlers have been used by plugging them into a power outlet, but in recent years handy types that use a gas combustion heating method have become popular. However, the ignition method of this portable hair curler is a heater ignition using a battery, which has the problem that it takes time and effort to replace the battery, and the battery itself and its replacement are expensive.

As a hair curler that solves these problems, an ignition method using a high voltage generator can be considered. FIG. 1 shows an igniter for hair curlers that was previously proposed by the present inventors based on such a concept, and will be explained below.

In the figure, 1 is a gas combustion tube of the main body of the hair curler, 2 is a high voltage generator, and 3 is a housing for the high voltage generator 2, which is inserted into the head of the gas combustion tube 1 from the open end surface, and is fitted with an engaging claw. 3a is a unit case that is engaged with the engagement hole 1a. Reference numeral 4 designates an operation button which is slidably inserted and fitted into the unit case 3 and presses the high voltage generator 2 into operation. The high voltage generator 2 has an inner case 2a containing an impact part (not shown) facing the gas combustion tube 1, and a piezoelectric element (not shown) that is impacted by the impact part.
The outer case 2b containing the high voltage generator 2 is installed in the unit case 3 so as to be located on the operation button 4 side. 5 is a discharge terminal that leads one electrode from the high voltage generator 2. Then, the outer case 2b of the high voltage generator 2 housed in the unit case 3 is pressed by the operation button 4, and the generated high voltage is passed from the high voltage lead wire 2c through the gas combustion tube 1 to the discharge terminal 5. The structure is such that an electric discharge is caused between the gas cylinders and the gas in the gas combustion cylinder 1 to be ignited.

However, in the above configuration, the outer case 2b of the high voltage generator 2 and the high voltage lead wire 2c are adhesively fixed, and when the operation button 4 is pressed, the high voltage lead wire 2c is connected to the outer case 2b together with the outer case 2b.
At the same time, the electrical connection between the high-pressure lead wire 2c and the gas combustion cylinder 1 became unstable, and the operational feel was also poor.

Purpose of the invention In view of the above-mentioned problems, the present invention aims to reliably guide the high voltage generated by the high voltage generator to the discharge gap, and to improve the operating feel by minimizing the number of operating sliding parts. The present invention is intended to provide a hair curler igniter that has a light effect.

Structure of the Invention In order to achieve this object, the igniter for a hair curler of the present invention includes a unit case inserted into and engaged with the head of the gas combustion cylinder of the hair curler body, and a piezoelectric element built into the unit case. The unit consists of a high voltage generator housed in the unit and an operation button for pressing the high voltage generator. It is built into a case so that one end is in contact with the gas combustion cylinder and the other end is in sliding contact with one electrode of the high voltage generator during a pressing operation. According to this configuration, high voltage can be reliably guided to the discharge gap, and since the number of operating sliding parts is reduced, the operating feel can also be improved.

DESCRIPTION OF EMBODIMENTS Hereinafter, an embodiment of the present invention will be described with reference to FIG. 2, with the same numbers assigned to the same parts as above.
As shown in FIG. 2, the present invention is characterized by a structure in which one electrode 2d of the high voltage generated by the high voltage generator 2 is guided to the discharge gap.
That is, in FIG. 2, 6 has one end 6a in contact with the gas combustion cylinder 1, and the other end 6b in contact with one electrode 2d of the high voltage generator 2 and the operation button 4.
This is an electrode plate built into the unit case 3 so as to slide into contact at the position shown by the dotted line when the electrode plate 6 is pressed. It is configured to be guided into the gas combustion tube 1 and to form a discharge gap with the discharge terminal 5. The other configurations are the same as those shown in FIG. 1 above.

Effects of the invention According to the hair curler igniter of the invention configured as described above, one end is connected to a gas combustion tube,
By providing an electrode plate whose other end is incorporated so as to slide into contact with one electrode of the high voltage generator during a pressing operation, high voltage can be reliably guided to the discharge gap. In addition, the operation feel can be improved by reducing the operating sliding surface, and in particular, if the electrode plate is made of a springy material, the electrical connection at each contact point will be reliable, and it will lead to high voltage. The only sliding parts during operation are one electrode of the high voltage generator and the springy end of the electrode plate, and because it is configured to slide only when pressed, it has an extremely good operating feel. can be taken as a thing. Furthermore, it has an advantage in terms of cost due to the semi-permanent lifespan achieved by employing a high voltage generator, and its practical effects are great.
