BRIEF SUMMARY
FIELD OF THE INVENTION
BACKGROUND OF THE INVENTION
This invention relates to a portable hair styling appliance utilizing an inflammable gas as a source of heat for curling hair, which is effective to accomplish safe and stabilized combustion and which is reduced in size by miniaturizing the construction.
DESCRIPTION OF THE PRIOR ART
Hitherto, in portable appliances necessitating a source of heat, most of them are primarily of electric type or of a type utilizing a fuel such as gas or petroleum. However, the electric type using fuel is inconvenient in that it requires a cord whereas, in the cordless type such as gas or petroleum, it is difficult to achieve the supply of a stabilized amount of fuel because the vapor pressure of the gas tends to vary remarkedly with temperature. For this reason, the use of a regulator can be contemplated, but it tends to lead to the increased size and also to the increased price for the appliance. Accordingly, no sufficient measures have been taken at present despite the fact that the pressure regulation is necessary in portable, compact appliances such as a hair styling appliance.
SUMMARY OF THE INVENTION
Accordingly, this invention is such that, by integrating a storage tank for an inflammable gas together with a regulator for adjusting the gas pressure and also by providing a gas inlet and outlet so as to orient them generally at right angles to each other, the gas pressure is rendered constant irrespective of change in temperature thereby achieving a safe and stabilized combustion and, at the same time, the whole construction can be rendered compact even though the regulator is used.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
A hair styling appliance according to one embodiment of this invention is shown in FIG. 1, and its basic construction comprises a body, a principal portion positioned at the tip thereof and a curler unit having a burner therein for styling hair. The combustion control of the burner is carried out through a switch manipulating unit provided in the body. While FIG. 2 shows the construction thereof, a body casing 1 constituting the body is covered by a body cover 2 and, within the interior of the body defined by them, there is accommodated a tank 3 for the storage of an inflammable gas and a pressure regulator 4 for adjusting the gas pressure. The pressure regulator 4 is fitted with a nozzle support 5 having a nozzle 7 mounted thereon through a nozzle holder 6 so as to extend in parallel to the pressure regulator 4. The nozzle 7 is in turn connected to a burner 9 through a piping 8. The burner 9 has an air intake port 10 defined therein for the introduction of air thereinto from the outside. In the body casing 1, a switch knob 12 mounted in a switch support 11 is provided in a manner biased in one direction by a spring 13, thereby constituting a switch manipulating unit. A switch terminal 14 movable to and fro in response to the forward and backward movement of the switch knob 12 is also mounted o
