Description

[Detailed Description of the Invention] This invention relates to a device in which liquefied gas is brought into contact with a catalyst member and combusted, and the combustion heat is used for hair conditioning.

A liquefied gas tank is installed inside the handle, and the liquefied gas is combusted by a catalyst in a cylindrical iron member connected to the handle, heating the iron member from within, and then clamping it on the side of the iron member. Hairdressers that shape unfinished hair into a desired shape require heating of a catalyst.
The catalyst is heated by temporarily burning liquefied gas using electric heat.

In the conventional structure, the electric heating device that temporarily ignites and burns the liquefied gas is built into the tip of the trowel member using the heating cylinder.When using the device, first move the handle side control to open the combustion valve. Then, press the switch on the electric heating device to energize the nichrome wire coil, igniting and burning the liquefied gas that has flowed into the catalyst area. When the catalyst heats up due to this combustion, electricity is stopped and combustion is switched to the catalyst. Similarly, the prior art described in Japanese Patent Application Laid-open No. 56-5605 also
The ignition operation is performed at the tip of the iron member.

The disadvantages of such a case are that the opening/closing operation of the combustion valve and the ignition operation of the electric heating device must be performed separately, and that the electric heating device must be built into the tip of the trowel member, which is a problem in the structure. This is a drawback of the above.

This invention aims to eliminate the above-mentioned conventional drawbacks and provide a catalytic combustion type hair conditioner that can open and close the combustion valve and ignite using only an operator.

This invention will be explained in detail below using illustrated examples.

In the figure, 1 is a cylindrical synthetic resin handle, 2 is a metal heating cylinder, and has a comb tooth member 3 around it. Further, inside the handle 1, a liquefied gas tank 5 having a combustion valve 4 at the top and a voltage device 6 are arranged side by side. 7 is a valve pipe having a nozzle member 8, which is located under the catalyst member 16 attached to the lower end of the holder 12, and further has a discharge electrode connected to a piezoelectric device at the tip of the nozzle member 8. is arranged. In addition,
13 is an air hole, 14 is a cap, and 15 is a pilot.

An ignition lever 1 is rotatably provided on a support member 22 at the top of the liquefied gas tank 5 with a shaft 21.
8 has a first protrusion 18d and a second protrusion 18 on the upper side.
The cam has a continuous cam. The protrusions 18d and 18e are formed to have different heights in order to open the valve pipe 7 and maintain the valve open state.

Around the upper end of the valve pipe 7, an elevating member 23 having a protrusion on the lower side is loosely fitted with a rotation stopper (not shown), and a stopper 24 is provided on the upper part of the elevating member 23. It is fixed at And through them the valve pipe 7 is connected to the protrusion 18 of the cam.
d and 18e to move up and down. In addition, the valve pipe 7 has an inner pipe 25 that serves as a liquefied gas passage.
is inserted through the inner tube 25, and a nozzle member 8 equipped with an electrode 9 is connected to the tip of the inner tube 25. A flange member 2 made of a heat insulating material is provided around the lower part of the nozzle member 8.
6 is fitted, and on top of the flange member 26 is an L-shaped bimetal 27 extending from the heating cylinder side.
horizontal portions 27a are arranged at required intervals.

As shown in FIG. 3, the combustion valve 4 has a valve casing 4 fixed to the upper wall of the liquefied gas tank 5.
A has a valve body 4b inside the valve body, into which the lower part of the valve pipe 7 and the lower part of the inner pipe 25 are inserted. The lower end of the inner pipe 25 passes through the lower end of the valve pipe 7 and connects to the valve seat 2 provided in the lower part of the valve body 4b.
8, and a valve body 29 is fitted to its lower end. A flange 25a is formed around the lower end of the inner tube 25, and a coil spring 30 is provided between the flange 25a and the valve seat 28 to bias the inner tube 25 in the valve opening direction.

Flange portion 7a formed at the lower end of the valve pipe 7
A coil spring 32 for closing the valve, which is stronger than the coil spring 30, is provided between the valve body 4b and the lid member 31 of the valve body 4b. It is pressed onto 25a.

In the combustion valve 4 having such a structure, when the valve pipe 7 moves upward against the coil spring 32, the inner pipe 25 also moves upward. This movement is effected by the coil spring 30 and causes the valve to open. Further, while the valve pipe 7 is moved upward, the inner pipe 25 can be moved downward against the coil spring 30 to close the valve seat 28 with the valve body 29. These operations are performed by an operator 19 shown in FIGS. 5 and 7 connected to the ignition lever 18.

The operator 19 moves in a longitudinal groove 33 provided in the handle 1 made of synthetic resin. The inside of the handle 1 is protected by a metal flameproof plate 1a. The ignition lever 18 and the operating element 19 are connected to the protruding piece 1 inside the operating element.
They are connected by a lateral groove provided in 9a and a pin 34 movably fitted into the lateral groove. Controller 1
A lock button 35 is provided at the bottom of the handle 9 with a foot 35a that passes through the groove 33 and whose tip is located inside the handle 1.
is provided so that it can be moved in and out by applying a spring 35b, and at the end of the foot portion 35a, as shown in FIG. Claw 3 that fits into holes 36 and 37
Lock plate 38 with 8a bent on both sides
is attached with a snap spring 39.
A recess 19b is formed in the upper rear side of the operator 19, and a click spring 40 made of synthetic resin is inserted into the recess. This click spring 40 is a small semicircular protrusion 4 protruding from the handle 1 side.
1 and is used to hold the return of the operator 19 at a predetermined position.

Such an operator 19 can be moved upward using the thumb of the hand that grips the handle 1. When moving, first push in the lock button 35 with the pad of your thumb placed on the operator 19, push out the claw 38a of the lock plate 38 that fits into the hole 36 on the handle side from the hole 36, and then move the operator 19. is in a free state. Then, while holding down the lock button 35, push up the operator 19 until it stops.

Since the rear end 18 of the ignition lever 18 is connected to the protruding piece 19a of the operator 19 with a pin 34, the ignition lever 18 is connected to the pin of the support member 22 located on the liquefied gas tank 5. 42 and a torsion spring 20 provided over the rear end of the ignition lever, the ignition lever rotates clockwise about the shaft 21 as a fulcrum. This rotation causes the cam on the upper side of the ignition lever to push up the valve pipe 7 against the coil spring 32 in the valve body 4b via the lifting member 23 and the stopper 24. As a result, the pressing force on the inner tube 25 is released, and the inner tube 25
is pushed upward by the coil spring 30, the valve body 29 separates from the valve seat 28, and the valve opens. At the same time as the valve is opened, the liquefied gas flows into the internal passage of the inner tube 25 through the gap between the valve body 4b and the lower end of the inner tube, and flows out from the nozzle member 8 at the upper end of the inner tube.

Further, a little later than the opening of the valve, the actuating member 6a of the piezoelectric device 6 is pressed by the tip 18a of the ignition lever 18, actuating the hammer in the case 6b to impact the piezoelectric element and generate piezoelectricity. This piezoelectricity flows from the lead wire 10 to the electrode 11 and is discharged between it and the electrode 9 of the nozzle member 8, thereby igniting and burning the flowing liquefied gas. Air necessary for combustion is taken in through the air port 43 at the top of the handle 1.

If the catalyst member is heated by this combustion,
Extinguishes the flame in order to switch to catalytic combustion. This extinguishing of the flame is automatically performed by simply releasing the thumb from the operator 19 in the pushed-up position. When the pressure from the thumb is removed, the torsion spring 20 of the ignition lever 18 pushes the operator 19 together with the rear end 18b of the ignition lever 18 back to its original position, ie, counterclockwise. However, at the same time as the thumb is released, the lock button 35 also releases the coil spring 35b.
Lock plate 3 is returned to its original state by
The claw 38a of 8 fits into the upper hole 37, and the operator 1
Stop the return of 9. Further, at the fitting position of the claw 38a, the click spring 40 and the protrusion 41 are fitted, and resistance is generated there, so that the operator 19 is not returned by the torsion spring 20 and remains in the middle. . Further, on the ignition lever 18 side, the elevating member 23 moves up and down along the cam surface, and in the valley between the two protrusions 18d and 18c, the valve pipe 7 once descends together with the inner pipe 25, and the valve seat 28
is closed by the valve body 29, combustion is interrupted and the flame is extinguished. The counterclockwise rotation of the ignition lever 18 causes the elevating member 23 to come into contact with the protrusion 18d, and the elevating member 23 is pushed up again, causing the valve pipe 7 and the inner pipe 25 to rise and open the valve again. At this time, the actuating member 6
Since a does not operate, ignition does not occur and only the liquefied gas flows out to the catalyst member, and combustion occurs in the previously heated catalyst member in a flameless state.

Finally, if you want to stop this catalytic combustion, put your thumb on the operator 19 that is stuck in the middle, push in the lock button 35, and lock the lock plate 3.
After removing the claw 38a of No. 8 from the upper hole 37, the operator 19 is pulled down to its original position. Through this operation, the click spring 40 and the protrusion 41 are disengaged, the operator 19 and the ignition lever 18 return to their original positions, the combustion valve 4 is closed, catalytic combustion is stopped, and the piezoelectric device 6 is activated. The member 6a also returns to its original position and prepares for the next operation.

Also, the lock button 3 that occurs when you release your thumb
5 returns, the claw 38a of the lock plate 38
is fitted into the lower hole 36 to lock the operator 19 to the handle 1. Therefore, unless the operator 19 is operated with a fingertip, combustion will not occur, making it extremely safe.

Furthermore, when the lever member or the heating cylinder side becomes overheated during use, the inner tube 25 is pushed down via the flange member 26 against the coil spring 30 in the valve body 4b due to the deformation of the bimetal 29, and the inner tube 25 is closed. It becomes a valve state and the outflow of liquefied gas stops. As a result, catalytic combustion stops, but when the overheating subsides and the temperature drops, and the bimetal 27 returns to its original position and the pressing force is removed, the inner tube 25 rises again due to the coil spring 30, and the valve opens there. catalytic combustion begins again. The catalytic combustion will therefore be automatically regulated and there is no risk of overheating.

As mentioned above, this invention has a liquefied gas tank 5 having a combustion valve 4 and a piezoelectric device 6 inside.
The handle 1 has a cylindrical handle 1 equipped with an operator 19 that moves in a longitudinal groove 33 on the outside, a catalyst member 16 inside, and a comb tooth member 3 etc. on the outside.
It has a heating cylinder 2 attached to the open end of the liquefied gas tank and a cam integrally attached to its upper side, and is rotatably supported by a support member 22 on the upper part of the liquefied gas tank. an ignition lever 18 disposed across the ignition lever 18; a spring 20 that constantly presses the rear part of the ignition lever 18 downward to bring the cam into contact with the valve pipe 7 side of the combustion valve 4; The operating element 19 and the ignition lever 18 are arranged in a horizontal groove provided on the protrusion 19a inside the operating element, and a rear part of the ignition lever that is movably fitted into the horizontal groove. Since it is connected by the pin 34 at the end, both opening and ignition of the combustion valve can be performed continuously by simply moving the operator.

Therefore, there is no need to use both hands to open the valve and ignite the ignition as in the conventional method, and all operations can be performed with one hand, making it convenient for hair styling and easy to use. Furthermore, since the ignition source is a piezoelectric device, it does not require replacement unlike batteries, and can be used for a long time with only liquefied gas replenishment.

In addition, since the linearly moving operator and the ignition lever, which rotates around the shaft, are connected by a horizontal groove and a pin, misalignment of the connection point caused by the difference in the movement directions of both can be eliminated by the escape of the pin. Even when the ignition lever is moved via the operator, the movement is smooth and the ignition lever does not require much finger pressure to operate.
