The operation piece 13 is disposed on the outer surface of the outer frame 2 in which the lighter base 1 is housed. The operation piece 13 is disposed above the front surface 2a of the outer frame 2 and has a substantially fan-shaped concave portion 16 having a wider upper side. The lower part of the support shaft 14 is fixed by fastening the base of the support shaft 14 through the outer frame 2 and pressing the operation piece 13.
Is rotated, the support shaft 14 is rotated.

The valve opening / closing piece 12 has an upper edge 12a on one end side.
Into an arc shape, the arc-shaped lower edge 11a of the rotating piece 11
An engaging portion 12c is provided horizontally at the other end of the main portion 12b which is brought into contact with the movement of the lower edge 11a, and one end of the engaging portion 12c is opened and closed. The other end of the locking portion piece 12c, which is locked to the valve operating vertical pipe 17 and is located on the intermediate portion side of the main body piece 12b, is placed on a fulcrum portion 18 provided on the lighter base 1. The locking portion piece 12c placed on the fulcrum 18 swings about the other end as a fulcrum.

As described above, the drive piece 8 is engaged with the guide recess 7 so as to be vertically movable. However, the lighter base 1 corresponds to the position of the storage notch 10 when the drive piece 8 is lowered. Is provided with an engagement notch 19 to communicate with the storage notch 10.

The engagement notch 19 is formed by partially thinning the base 1, and when the support shaft 14 is rotated,
The rotating piece 11 that is inclined with the rotation of the piezoelectric element 5 is engaged with the rotating piece 11, and the engaged state is set via the driving piece 8 of the return spring provided in the piezoelectric element 5 or the driving piece 8 via the support shaft 14. By the upward biasing of the rotating piece 11 assembled by
Its upper end is locked and held by a receiving edge 20 formed by the upper edge of the engagement notch 19.

On the upper side of the rotary piece 12, outside the engagement notch 19, the other end of the intermediate piece 22 pivotally attached to the arm piece 6 a of the nozzle 6 by a pin 21 is connected to the pin 2.
3, the nozzle 6 is attached to a pair of support pieces 24, 24 provided on the lighter base 1, and a projection 2 provided on the side surface.
5, 25 are rotatably engaged and supported by the support pieces 24, 24. A receiving pin 29 is provided horizontally below the nozzle 6 on the support pieces 24, 24, and the arm piece 6a of the nozzle 6 comes in contact with this and moves in one direction (clockwise in FIG. 1).
The rotation of the intermediary piece 22 is restricted, and the intermediate piece 22 is rotated in the forward direction (counterclockwise in FIG. 1). That is, the receiving pin 29 has a function of positioning the nozzle 6 immediately below the first flame port 27, and the arm piece 6a of the nozzle 6 is pressed by the intermediary piece 22 in a designed direction (counterclockwise in FIG. 1). ) Rotate to.

The nozzle 6 and the vertical moving pipe 17 are connected to each other by a flexible pipe 26 made of synthetic resin.
The fixed position of the flexible tube 26 is secured by the positioning member 30 attached to the base 1.

Reference numeral 27 denotes a first flame port provided on the upper surface of the lid frame 3 (generally used for smoking cigarettes), and reference numeral 28 denotes a second flame port provided on the side surface (generally used for smoking chopped cigarettes). In any case, when the nozzles 6 face each other, a combustion flame is ejected.

The first and second flame ports 27 and 28 communicate with each other via a long hole 31 so that the presence of the long hole 31 does not extinguish the fire when the combustion flame is converted. The long hole 31 also serves as an inlet for air (oxygen). Illustration 3
2 is an air inlet.

When the operation piece 13 is depressed, the support piece 14 is provided with the support shaft 14, so that the support piece 14 is engaged with the rotary piece 11 and the through hole 15 integrated with the support shaft 14. The combined drive piece 8 descends along the guide recess 7. Drive piece 8
As a result, the operation element 5a is pressed and descends, and as a result, the piezoelectric element 5 is instantaneously discharged, and it is scattered from the tip of the ignition wire toward the nozzle 6 and scatters.

On the other hand, the lower edge 11a of the rotating piece 11a pushes the valve opening / closing piece 12 at the upper edge 12a of one end by the lowering of the rotating piece 11 accompanying the driving piece 8, so that the fulcrum 18 with respect to the one end is pressed. The other end of the valve rises, and the locking piece 12c of the valve opening / closing piece 12 pushes up the vertical pipe 17 so that the opening / closing valve in the fuel tank 4 linked with the vertical pipe 17 is opened. The fuel gas is ejected from the nozzle 6 through the vertical movement pipe 17 and the flexible pipe 26 in order, and the spark is ignited, and becomes a combustion flame and is ejected through the first flame port 27.

In this state, when the fingertip is released from the operation piece 13, the members such as the driving piece 8 and the rotating piece 11 return to their original positions by the action of the return spring built in the piezoelectric element 5.

Also, if you keep your fingertips,
The gas continues to burn. At this time, when the operation piece 13 is rotated about the support shaft 14, the rotation piece 1 integrated with the support shaft 14 is turned on.
1 rotates, and the intermediate piece 22 presses the nozzle 6 with the arm piece 6a by the rotation of the rotating piece 11. Since the supporting portion of the nozzle 6 by the protrusion 25 and the pivotally connecting portion of the intermediate piece 22 via the arm piece 6a are different, the arm piece 6a by the intermediate piece 22 is different.
When the nozzle 6 is pressed, the nozzle 6 rotates around the protrusion 25 (the direction of rotation is determined by the presence of the receiving pin 29), and the combustion flame is ejected from the second flame port 28 side. (Nozzle 6 for the first flame port 27 or the second flame port 28
Is determined at the time of design).

When the fingertip is released from the operation piece 13 in this state, the return spring in the piezoelectric element 5 is in a free state, and the drive piece 8 tries to rise along the guide recess 7. Since the upper end of the moving piece 11 is locked by the receiving edge 20 formed by the upper edge of the storage notch 10, its rise (and also the rising of the rotating piece 11) is regulated. Keeps pushing the valve opening / closing piece 12, so that the gas is continuously ejected from the fuel tank 4 and the combustion flame is continuously ejected from the second flame port 28.

When the operation piece 13 is rotated and the rotation piece 11 is inserted into the storage notch 10 from the engagement notch 19, the combustion gas is ejected from the first flame port 27 side. When the fingertip is released from the operation piece 13, each member such as the drive piece 8 returns to the original position by the return spring, and the combustion flame is extinguished.
