Description

[Detailed description of the invention] [Industrial application field] This invention uses a catalyst to combust a mixed gas of liquefied gas and air flowing out from a tank inside the handle in a heating cylinder connected to the handle. This invention relates to a temperature adjustment mechanism in a device that uses heat to condition hair.

[Conventional technology]

Temperature adjustment in this type of hair conditioner was developed in Japanese Patent Application Publication No. 56
A rod-shaped bimetal member is used as described in Japanese Patent No. 5605. This bimetallic member is installed between the heating cylinder and the combustion pipe, and converts the deformation of the bimetallic member due to temperature changes inside the heating cylinder into a pressing force on the valve stem through the members surrounding the injection nozzle, thereby causing combustion. It consists of a structure that adjusts the temperature by controlling the flow rate of liquefied gas from the valve.

[Problem that the invention attempts to solve]

In the above conventional example, the injection nozzle is equipped with a link device that converts the deformation of the bimetal into pressing force, which makes the structure around the injection nozzle complicated, and the pressure plate that acts on the injection nozzle is balanced by upper and lower elastic members. Because of this, precision is required, and there are problems such as failures are likely to occur.

This invention was devised to solve the above-mentioned conventional problems, and its purpose is to transmit the pressing force caused by the deformation of the bimetal plate to the combustion tube without using a link device or the like. Controls the flow rate of liquefied gas at the combustion valve via the combustion pipe, which facilitates temperature adjustment.
It is an object of the present invention to provide a temperature control mechanism with a new structure capable of appropriately adjusting the effect of bimetal using an adjustment piece.

[Means for solving problems]

This invention for the above purpose includes a liquefied gas tank having a combustion valve in the handle and an ignition device,
In a gas combustion hair conditioner that has a catalyst member for gas combustion inside a heating cylinder connected to a handle, the tip of a combustion tube is connected to a movable nozzle of a combustion valve and is rotatably positioned at the bottom of the catalyst member. The periphery of the part is formed into a threaded part, and an adjustment piece having an engaging stepped part on the side surface is screwed into the threaded part so as to be movable up and down, and the rear end is fixed to a support member in the heating cylinder. The tip of the bimetal plate is inserted into the engagement step to connect the adjustment piece and the bimetal plate.

[Effect]

In the above structure, when the mixed gas of liquefied gas and air flows out from the combustion tube into the heating cylinder, it comes into contact with the catalyst member and burns. When the temperature inside the heating cylinder rises above the deformation temperature of the bimetal plate, the free end of the bimetal plate, that is, the tip side, deforms downward and presses the adjustment piece, causing the combustion tube to push the movable nozzle and release the liquefied gas at the combustion valve. Stop injection. When this temporarily stops catalytic combustion and the temperature drops, the bimetallic plate returns to its original shape, the pressing force is removed, everything returns to its original state, and liquefied gas is ejected again, causing catalytic combustion.

〔Example〕

In the figure, reference numeral 1 denotes a handle, which is equipped with a liquefied gas tank 3 having a combustion valve 2 therein, and an ignition device 4 consisting of a piezoelectric unit. The combustion valve 2 has a movable nozzle 5 that opens and closes an internal valve body, and a combustion tube 6 having a driver groove 6b at its open end is rotatably connected to this movable nozzle. Furthermore, the movable nozzle 5 and the movable member 4a of the ignition device 4 have a handle 1.
A lever member 7 is attached to the side portion of the lever member 7 so as to be slidable in the horizontal direction, and an operator 8 is attached to the side portion of the lever member 7 so as to be freely movable in the vertical direction.

9 is a heating cylinder connected to the tip of the handle 1;
A comb tube is fitted on the outside. Inside the heating cylinder 9, the combustion tube 6 and a cylindrical catalyst member 10 are housed one above the other, and the open end of the combustion tube 6 is located at the bottom of the catalyst member.

A threaded portion 6a is formed around the tip of the combustion tube 6, and an adjustment piece 11 is screwed into the threaded portion 6a so as to be movable up and down. Engagement step portions 12 are formed by chamfering on both sides of the adjustment piece 11, and the tip of the bimetal plate 13 can be inserted into the engagement step portions.

The bimetal plate 13 is bent into an L-shape and has a bifurcated tip. The rear end of this bimetal plate 13 is fixed to a support member 14 placed in the heating cylinder 9 from the handle side.

In the figure, 15 is a coil spring for compressing the catalyst member, and 16 is a cap.

In the above structure, when the combustion temperature of the liquefied gas by the catalyst member 10 becomes higher than the deformation temperature of the bimetal used therein, the free tip side of the bimetal plate 13 deforms downward from the bent part. Then, the engagement step portion 12 of the adjustment piece 11 is pressed. As a result, the combustion tube 6 is pushed down together with the movable nozzle 5, and the valve in the combustion valve 2 is closed.
The flow of liquefied gas stops. As a result, combustion by the catalyst member 10 is temporarily stopped, and the temperature inside the heating cylinder is lowered.

As the temperature decreases, the bimetal plate 13 returns to its original state, and the pressing force via the adjustment piece 11 is removed, so the combustion valve is opened again and the liquefied gas flows out. Then, catalytic combustion begins.

Temperature control can be easily performed by rotating the combustion tube 6 with a screwdriver and adjusting the height position of the adjustment piece 11. When the adjustment piece 11 is set high, even a slight deformation of the bimetal plate 13 causes a pressing operation, stopping the outflow of liquefied gas.
On the other hand, if it is set low, no pressing force will be generated unless it is significantly deformed. Therefore, if the adjustment piece 11 is set at an appropriate position based on the deformation temperature of the bimetal, a constant temperature can be maintained at all times.

(Effect of the invention) As described above, this invention forms a threaded portion 6a around the tip of the combustion tube 6 located below the catalyst member 10 in the heating cylinder 9, and an engaging stepped portion is formed on the threaded portion 6a. An adjustment piece 11 having an adjustment piece 12 on the side surface is screwed together so as to be able to move up and down, and the tip of an L-shaped bimetal plate 13 whose rear end is fixed to a support member 14 inside the heating cylinder is inserted into the engagement step 12. Intricate adjustment piece 11 and bimetal plate 13
Since the combustion valves are connected to each other, the opening and closing of the combustion valve occurs in synchronization with the deformation of the bimetal plate, and the temperature inside the heating cylinder is always kept constant. In addition, the deformation of the bimetal plate is transmitted to the combustion valve via the adjustment piece at the tip of the combustion tube that moves up and down with a screw, so the distance between the tip of the bimetal plate and the engagement step of the adjustment piece can be adjusted to The temperature can be set within a predetermined range, and the adjustment piece can be moved just by rotating the combustion tube, so adjustment is not a hassle, and the structure is such that the rear end is fixed to the adjustment piece that is screwed onto the combustion tube. Since it is only necessary to engage the tips of the L-shaped bimetal plates, it has the advantage of being simpler than conventional ones.
