Description

DETAILED DESCRIPTION OF THE INVENTION The present invention operates a combustion gas valve in conjunction with an electrical switch operation using a switch operating body, and can be used even when the movement of the switch operating body and the direction of the valve operation are not the same. To provide an ignition device for a combustion device which can be used even if the operating distance of a switch operating body and the valve operating distance are different.

When the heat source of a small combustion application device, such as an electric hair curling roll brush, is obtained from gas combustion instead of a power source, the operation of opening and closing the heater circuit for ignition and the operation of the valve to drain the gas are required. It is very inconvenient to perform these two operations at the same time. Additionally, normally, micro flow valves, such as lighter valves, have an operating stroke of 1 mm to 3 mm.
On the other hand, when a person performs a switching operation by hand, the sliding distance of the switch is preferably about 5 mm to 7 mm. Also, if the sliding direction of the switch and the operating direction of the valve are the same, the valve can be operated relatively easily, but if the sliding direction is the opposite,
Structurally difficult.

The present invention focuses on the above points, and examples will be described below. The figure shows a hair curling roll brush. Figure 1,
To explain based on FIG. 2, inside the main body case 1,
A tank 2 that stores LP gas as a heat source is housed, and a valve 3 is installed in front of the tank 2.
The base of the burner 5 is connected to the burner 5 by a hose 4. Further, a switch operation body 6 is slidably provided on the main body case 1, and by lowering the switch operation body 6 backward, a plate-shaped member 7 is lowered.
As a result, a similar member 8 rotates around its central fulcrum, moves the washer 9 attached to the valve 3 forward, and lifts the valve 3 to discharge LP gas. The discharged LP gas passes through a hose 4, a burner inlet 10, a filter 11, and is throttled by a regulating member 12 having micropores to increase the flow rate. As a result, air is simultaneously taken in from the intake hole 13 by the ventilate effect, and is ejected from the burner outlet 14 into the curl pipe 15 as a mixture of air and LP gas. The LP gas discharged from the burner outlet 14 is supplied to the heater 20, which is powered by the battery 19 inside the main body case 1, and a circuit is formed by the contact between the switch terminal 24 that slides together with the switch operating body 6 and the battery terminal 23. This hits the catalyst 21 heated to the catalytic combustion start temperature of the LP gas, starts catalytic combustion, and heats the curl pipe 15 from inside.

LP gas is supplied to the tank 2 through a gas inlet 17 to a gas injection valve 16 located at the rear of the tank 2.
Then, insert the gas lighter cylinder 18 in the same way as when supplying gas to a gas lighter.

When the temperature of the catalyst 21 rises to a temperature at which catalytic combustion of LP gas can continue, the switch operating body 6 is reversely moved forward beyond the intermediate point to break contact between the switch terminal 24 and the battery terminal 23, turn off the heater 20, and turn off the LP gas. Only a mixture of gas and air is sent out to continue catalytic combustion and extend the life of the battery 19.

22 is the battery cathode terminal, 25 is the curl pipe 15
26 is a cap that covers the tip opening of the curl pipe 15, 27 is an exhaust hole provided in the cap 26, 28 is a brush holder, and 29 is a cylinder injection plug.

Next, based on Figures 3 and 4, switch operation body 6
The heater circuit operation and valve operation mechanism will be explained below. Fig. 3 shows the state before the switch mechanism operates, and Fig. 4 shows the state when the switch is operated. By sliding the switch operating body 6 to the left in the drawing, that is, to the front, the switch can be operated. The terminal 24 and the battery terminal 23 come into contact and are electrically connected. At the same time, the protrusion 30 provided on the switch operating body 6 pushes down the protrusion 31 of the member 7, so that the member 7 moves to the fourth position around the fulcrum 32.
Tilt as shown. As a result, the point of force 33 of the member 7 pushes the point of force 34 of the member 8, and the member 8 pushes the point of force 34 at the fulcrum 3.
As shown in FIG. 4, the point of action 36 of the tilting member 8 pushes against the washer 9, centering on the valve 3, and pulls up the valve 3 to discharge gas. When ignition is confirmed and the heater 20 is turned off and only the gas is spouted, the switch operating body 6 is moved backward to disconnect the switch terminal 24 and the battery terminal 23, and the protrusion 30 is brought onto the protrusion 37. , the nozzle 3 is pulled up and the gas flows out in the same manner as described above. In addition, the lifting distance of the nozzle 3 and the sliding distance of the switch operation body 6 are determined by the fulcrums 32, 35 of the members 7, 8, the point of force,
It can be set arbitrarily by changing the distance between the points of action 33 and 36. Similar settings can also be made by changing the heights of the protrusions 31 and 37 of the member 7. Note that when the heater 20 is turned off after ignition and only the gas is spouted, the valve 3 is temporarily closed during the operation, but the protrusion 30
The transition from 1 to the protrusion 37 is instantaneous, and during this time the temperature of the catalyst does not drop to a point where it cannot be combusted, allowing catalytic combustion to continue.

In this way, the switch device of the combustion device of the present invention allows switch operation and valve operation with one switch operation body, and the direction of operation of the switch and the direction of operation of the valve may be opposite, and the operation distance of the valve can be It is something that can be changed freely. Therefore, it not only has good operability but also allows for free design and good manufacturability. In addition, by moving the switch operating body forward, the heater circuit is turned on and the valve is opened, allowing ignition.
After ignition, the heater circuit can be turned off and the valve can be opened by retracting the switch operating body. Therefore, after ignition, gas can be continuously burned without consuming the battery.
