Definitions

  • the invention relates to a hair styling appliance comprising a body portion having a tank for the storage of inflammable gas, a gas pressure regulator and a control valve for controlling the gas flow to a burner; and a curling unit positioned at the front end of the body pcrtion, having a burner for heating the curling unit, a catalyst and an electric heater for igniting the inflammable gas.
  • the appliance according to the invention is characterized in that the electric heater is placed between two spaced catalysts within the curling unit in front of the burner; that the control valve is being controlled, together with an electric switch for energizing the heater, by a switch knob positioned within the body portion; and that the control valve is placed sideways in parallel to the gas pressure regulator, the gas outlet connecting the gas pressure regulator with the control valve extending substantially at a right angle to the gas inlet connecting the tank with the gas pressure regulator.
  • 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 gas inlet and outlet so as to orient generally at right angles to each other, the gas pressure is rendered constant irrespective of change in temperature thereby to achieve a safety and stabilized combustion and, at the same time, the whole construction can be rendered compact even though the regulator is used.

  • a hair styling appliance according to one embodiment of this invention is shown in Fig. 1, and its basic construction comprises a body accommodating function elements such as an ON/OFF switch and 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 being carried out through a switch manipulating unit provided in the body.
  • 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.
  • 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 on the switch support 11.
  • the switch terminal 14 has a contact area 15 at the tip thereof which faces a conductor area 17 on a switch board 16.
  • an inflammable gas emerging from the tank 3 flows through the pressure regulator 4 and, after having passed in a pressure controlled manner through the nozzle support 5 and the nozzle holder 6, is discharged from the nozzle 7. It is so designed that the supply of the inflammable gas can be effected by moving the switch support 11 forwards to pull the nozzle 7 fowards thereby to allow a valve to open.
  • the inflammable gas emerging from the nozzle 7 then enters the burner 9 through the piping 8 and is, after having drawn in air through the air intake port 10 by the venturi effect, jetted in the form of a mixed gas of air and inflammable gas from the burner 9.
  • the tip of the burner 9 is located inside a heater holder 18 of electrically insulating material provided at one end of the body casing 1. Accordingly, the mixed gas flows through the inside of the heater holder 18 and then impinges upon a first catalyst 20 at the tip of the heater holder 18.
  • the first catalyst 20 and a second catalyst 21 are retained by a catalyst retainer 22 and a heater 19 is positioned sandwiched therebetween.
  • the heater 19 is such that, when the switch support 11 is moved forwards to pull the nozzle 7 operable to open and close the inflammable gas flow and the switch knob 12 is then depressed, the contact area 15 of the switch terminal 14 moves downwards and then contacts the conductor area 17 of the switch board 16 to establish a closed circuit through connectors 23 and 26 and lead wire 27 whereby the mixed gas is heated by the heater 19 to a temperature at which it undergoes a catalytic combustion.
  • the mixed gas is catalytically burned by the first and second catalysts 20 and 21, the temperature of each of which has been raised, and generates heat energies which in turn increase the temperature of a curling pipe 24 positioned exteriorly thereof thereby increasing the temperature of a brush 25 exteriorly of the pipe to a value suitable for hair styling.
  • the body cover 2 there are arranged batteries 30 between terminals 31 and 32 and positioned in recesses defined in the tank 3 in parallel relation to the tank 3.
  • the terminal 32 is connected to a heater circuit through a lead wire 33.
  • a cap 36 is removably mounted on one end of the body cover 2 and is formed with a plug-in aperture 37 in alignment with an inflammable gas injection port 35.
  • the cap 36 can be selectively removed from and mounted on the body cover 2 by compressing a gripping area 39 to manipulate a fitting area 38.
  • the gas cylinder 40 is used to inject the gas into the tank 3 with its nozzle 41 inserted through the plug-in aperture 37.
  • the inflammable gas stored in the tank 3 may be an LP gas including butane or propane as its main component.
  • the tank 3 and the pressure regulator 4 are made of resin and are integrally connected together by fusing at a weld area 45 while engagement indents 43 are engaged with positioning area 44 for the engagement indents in a non-rotatable manner. Because of this, no piping between the tank 3 and the regulator 4 is required, thereby making it possible to minimize the size with the increased reliability and strength of the sealed interface.
  • the welding at the weld area 45 is carried out by the use of an ultrasonic wave.
  • the nozzle support 5 is also fusion bonded to the regulator 4 by the use of an ultrasonic wave.
  • the gas outlet 47 is provided on a side face of the regulator 4 so as to face in a direction substantially at right angles to the gas inlet 46 of the regulator 4. This is for the purpose of minimizing the longitudinal dimension so that the appliance can be rendered compact when the nozzle 7 is pulled by the switch support 11 through a ring 42.
  • the pressure regulation will now be described.
  • the LP gas enters the gas inlet 46 in the form as gasified through a cotton wick 48 after the pressure has been reduced by an urethane washer 51 compressed by an urethane retaining screw 50 sealed by an 0-ring 49.
  • the pressure adjustment is such that a diaphragm 54 adapted to receive a pressure from front by the action of a pressure adjusting spring 53 compressed by a pressure adjusting screw 52 and also to receive a gas pressure from rear is displaced to and fro by the difference between the gas pressure and the spring force whereby, when the gas pressure is high, a pressure adjusting pin 55 reduces a clearance between it and a pressure adjusting packing 56 to reduce the gas pressure in the gas outlet 47, whereas when the pressure in the gas inlet 46 is low, the diaphragm 54 is displaced rearwards and, therefore, the action reverse to that described above takes place to increase the gas pressure in the gas outlet 47, wherefore the gas pressure in the gas outlet 47 can be kept constant.
  • nozzle packing 57 is a nozzle packing for interrupting and establishing the flow of the gas towards the nozzle 7, and the nozzle 7 is sealed by a nozzle 0-ring 58 and applied with a force by a nozzle spring 59, non-removably set in position by a nozzle spring retainer 60, in a direction necessary to interrupt the flow of the gas.
  • the nozzle 7 On one side adjacent the nozzle packing 57, the nozzle 7 is formed with a gas passage 34 through which the inflammable gas flows into the nozzle 7.
  • Fig. 5 illustrates an interior structure of the burner 9.
  • the gas supplied through the piping 8 flows into the burner 9 through an inlet portion 62 in a burner inlet piece 61.
  • a washer 64 having a fine aperture 63 (10 to 200 11m in diameter was appropriate) forming an orifice necessary to accelerate the flow of the gas in an amount necessary to achieve combustion and to draw the air through the air intake port 10 by Venturi effect.
  • This fitting is carried out by threading a washer retainer 66, having a filter 65 of sintered metal alloy built therein, to seal so that the gas can be swept off.
  • a safety valve 69 having a T-shaped packing 68 at the tip thereof is positioned as shown in Fig. 7.
  • the safety valve 69 is, while applied with a pressure by a safety valve spring 70, inserted in a safety metal 71 having a gas passage 72 of a shape as shown in Fig. 8, and the safety metal 71 pressure-fitted into the burner inlet piece 61.
  • a unit portion of the heater holder 18 is shown in Fig. 9 while a structure with the catalysts 20 and 21 removed is shown in Fig. 10.
  • This unit is featured in that, since the life time of each of the heater 19 and the catalysts 20 and 21 is approximately 100 hours, the connectors 23 supporting the heater 19 and the connectors 26 secured in the body casing 1 are releasably engaged to each other in readiness for the replacement and in that the heater holder 18 is provided with support steps 80 and 81 for holding the catalysts so that the heater 19 and the catalysts 20 and 21 can be kept assurediy in predetermined contact with each other, to achieve an assured ignition.
  • Fig. 11 illustrates a structure for facilitating the confirmation of an ignited condition and the detection of the combustion temperature.
  • the previously mentioned curler cap 28 is provided with a spiral bimetal 76 having a portion connected to the curler cap 28 and the other end secured to a bimetal shaft 75 as shown.
  • the combustion temperature at a particular time can also be ascertained.
  • the exhaust gases are adapted to flow through the clearance 29.
  • a skirt 78 is so provided to avoid a danger due to the forward flow of the exhaust gases.
  • the water vapor of the exhaust gases is adapted to be guided by the skirt 78 towards the brush 25 and then towards the hair to facilitate the hair styling.
  • the body cover 2 is, as shown in Fig. 1, provided with a slit 79 so that the tank 3 can be viewed from the outside to check the liquidized gas remaining in the tank 3. Moreover, by providing this slit 79 at two diametrical locations, light is allowed to pass so that the amount of the liquidized gas remaining in the tank 3 can more easily be checked.
  • the tank 3 has generally cylindrical recesses at its upper portion for accommodating batteries 30 shown by the chain lines. Therefore, the various elements can be accommodated within the cylindrical body, thereby rendering it compact.
  • the hair styling appliance of this invention has its entire structure rationalized and rendered compact even though the pressure regulator is used, because the use is made of the pressure regulator for adjusting the gas pressure at a constant value irrespective of change in temperature so that safety and steady combustion can be attained and because the tank for the storage of the inflammable gas and the pressure regulator are integrated together with the gas outlet arranged substantially at right angles to the gas inlet.
