(Prior Art) Conventionally, a smoking lighter is known in which an ignition block body including an ignition mechanism is attached to an upper opening of a lighter casing, and the opening is closed by the ignition block body of the lighter casing. Such an ignition block body is generally fixed by inserting a threaded rod from above and screwing it onto the upper wall of the fuel tank located below the rod.

However, in fixing such an ignition block body, since a threaded rod is used, there is a risk that the head of the threaded rod will be exposed to the outside and look unsightly. This had the disadvantage of complicating the structure of the fuel tank, since screw holes had to be formed for the fuel tank.

(Problems to be Solved by the Invention) This invention aims to solve the drawbacks of the conventional smoking lighter ignition mechanism mounting device. The ignition block body is fixed by utilizing the elastic force of the elastically actuated spring means of the lid which opens and closes the upper surface of the lighter casing.

(Means for Solving the Problems) Technical means taken by the present invention to solve the above problems include: a pyrotechnic block body that holds a flint storage tube and closes the upper surface of the lighter casing; A spring is installed between the lid and the lid that biases it in the opening direction when the lid is opened and in the closing direction when the lid is closed, and the spring's elastic force presses the ignition block body and the lid in opposite directions. At the same time, the ignition block body is pressed downward, the fuel tank is brought into contact with the lower part of the ignition block body, and the ignition block body and the lighter casing are engaged with each other by means that can be hooked and removed by movement against the elasticity of the spring. It is characterized in that the firing block body is prevented from slipping out upward.

(Embodiments) Preferred embodiments of the present invention will be described below with reference to the drawings. In the figure, reference numeral 1 denotes a flat rectangular cylindrical lighter casing with both upper and lower surfaces open, the upper surface of which can be opened and closed with a lid 2, and the lower surface closed with a detachable bottom lid 3. A fuel tank 4 is inserted into the lighter casing 1 from below and held therein, and is fixed to the bottom cover 3 with a set screw 5. The fuel tank 4 is provided with a combustion valve device 6 and an injection valve device 7, which are attached to the fuel tank by vertically penetrating the tank.

The combustion valve device 6 has a flow rate adjustment mechanism that can be operated from below the lighter through the bottom cover 3, and a burner valve mechanism that has a nozzle pipe that extends above the tank and is opened and closed in conjunction with the opening and closing of the cover 2. , fuel tank 1

The flow rate adjustment mechanism includes a porous adjustment plate 10 that adjusts the amount of fuel gas passing through it by being compressed, and a porous adjustment plate 10 that is screwed back and forth in the axial direction inside the fixed cylinder 8 to push the porous adjustment plate 10. It is provided with an adjustment screw 11 that changes the pressure and an operating barrel 12 that rotates the adjustment screw 11.

The adjustment screw 11 and the operation barrel 12 are the adjustment screw 11
The operation tube 12 is inserted into the slit 13 formed from below.
By inserting the upper plate-shaped portion 14 of the two, they are engaged with each other only in the rotational direction, and are connected with each other while being free to move relative to each other in the axial direction. A second adjustment screw 11a is screwed into the center of the adjustment screw 11, and the second adjustment screw 11a moves along the movement of the first adjustment screw 11, particularly in the axial direction integrally with the operation barrel 1.
Only the second adjusting screw 11a can be screwed forward and backward in the axial direction by a driver inserted through the center hole of the second adjusting screw 11 from below. As a result, the flow rate can be adjusted by the first adjustment screw 11 via the operation tube 12,
Double adjustment is possible, including flow rate adjustment by screwing the second adjustment screw 11a back and forth.

The burner valve mechanism includes an on-off valve 17 with a nozzle pipe 15 connected to the upper end and a valve body 16 on the lower end, and a spring 18 that always biases the on-off valve 17 in the valve closing direction.
including. The valve body 16 opens and closes the through hole 19 by coming into contact with and separating from the upper surface of the through hole 19 that vertically penetrates the partition wall 9 .

The lower chamber of the fixed cylindrical body 8 communicates with the fuel tank 4 through a communication hole 20, and the entrance of the communication hole 20 is blocked by a porous vaporization promoting substance 21 inserted into the fuel tank 4. The liquefied fuel gas in the fuel tank 4 is supplied into the combustion valve mechanism 6 in a vaporized state. This makes it possible to adjust the flow rate and stabilize the flame. 22 is a plug that seals the hole 23 for charging the porous vaporization promoting substance 21 into the fuel tank 4.

One side of the fuel tank 4 is formed into an L-shape cut out from above, and the rotating wheel 24 of the firing file is received there, and the supporting shaft 2 of the rotating wheel 24 is received there.
A shaft hole 26 into which the lower part of the shaft 5 is inserted is formed. Two shaft support plates 27 are formed parallel to each other with an interval on the upper surface of the fuel tank 4, and a lever member 28 is positioned between the shaft support plates 27, and is pivotally supported by a pin 29 so as to be swingable. . The lever member 28 has one end connected to the on-off valve 1.
The forked portion 30 that engages with the upper end of the
The nozzle pipe holding part 31 is composed of two orthogonal plates facing each other. Nozzle pipe holding part 31
is between two orthogonal plates as shown in Figure 5.
The nozzle pipe 15 is inserted through and held to prevent the nozzle pipe 15 from rotating. This makes it easy to align and insert the nozzle pipe into the nozzle pipe insertion hole formed in the ignition block body, which simplifies assembly.

32 is an ignition block body, and a fuel tank 4
The lighter casing 1 is assembled at the upper part of the lighter casing 1, and closes the open upper surface of the lighter casing 1. The ignition block body 32 has a casing side hinge member 33 on one side.
A protrusion 34 that engages with the lower surface of the lighter casing 1, and a protrusion 36 that engages with the groove 35 on the inner surface of the lighter casing 1 on the other side.
In addition, a recess 38 for receiving a flint storage pipe 37 is formed on the upper surface.

The flint storage pipe 37 has a flint hole 40 therein which opens toward the flint file wheel 39 attached to the tip, and a flint push spring 4 that presses the flint stone 41.
2 and a stone push spring 43 that supports the stone push spring.
The recess 38 is open toward one side, and the flint storage pipe 37 can be rotated outward to allow the flint to be replaced.

A spring receiver 47 is bridged between a pin 44 provided on the ignition block body 32 and a pin 46 provided on a hinge member 45 on the lid 2 side, and receives the elastic force of a spring 48 housed inside. Since the ignition block body 32 and the lid 2 are pressed in opposite directions, and the pin 44 on the ignition block body 32 side is located lower than the pin 46 on the lid side, the ignition block body 3
2 is pressed downward. The position of the pin 46 on the lid side moves up and down beyond the position of the shaft pin 49 that pivotally supports the lighter casing 1 and the lid 2 when the lid is opened and closed, and biases the lid 2 in the closing direction or opening direction. . The other protrusion 36 is provided in the groove 3 between one side of the ignition block body 32 and the hinge member 33 on the casing side.

The claw 54 is engaged in the groove 53, and the claw plate 55, which is located on the other side and projects laterally, is engaged in the groove 56 on the other inner surface of the lighter casing 1. By tightening, it is fixed to the lower part of the lighter casing 1.

The lower part of the operation barrel 12 has a protrusion 58 that engages with the inner circumferential surface of the recess 57 of the bottom cover 3, and the engagement of the protrusion 58 prevents the operation barrel 12 from rotating beyond a certain level. As a result, the range of the flow rate adjustment amount is restricted, and unexpectedly large flames are prevented from forming. As shown in FIG. 3, when the lid 2 is rotated upward for ignition, the spring receiver 47 is rotated upward around the pin 44, so the tip of the spring receiver 47 moves downward and is levered. The member 28 is swung. As a result,
The on-off valve 17 is lifted to allow fuel gas to be ejected, and the fuel gas is ejected upward from the nozzle pipe 15. Then, the rotary wheel 24 is rotated and the ignition file wheel 39 rubs the flint stone 41 to generate a spark and ignite it.

(Effects of the Invention) According to the ignition mechanism mounting device for a smoking lighter of the present invention, the ignition block body that holds the flint storage tube and closes the upper surface of the lighter casing, and the lid, when the lid is opened, A spring is provided that biases the lid in the opening direction and biases it in the closing direction when the lid is closed, and the spring's elastic force presses the ignition block body and the lid in opposite directions while simultaneously pushing the ignition block body downward. At the same time, the fuel tank is brought into contact with the lower part of the ignition block body, and the ignition block body and the lighter casing are engaged by a removable means by movement against the elasticity of the spring, and moved above the ignition block body. Since the ignition block is designed to prevent the ignition block from slipping out, it is possible to attach the ignition block to the lighter casing without being associated with the fuel tank, which simplifies the structure of the fuel tank and facilitates assembly of the ignition block. It is possible to reduce assembly costs.
