Description

  The present invention relates to an igniter that ejects flame from a nozzle, and more particularly to an igniter equipped with a safety mechanism for ensuring safety.

Conventionally, an igniter, such as a torch burner, is mounted on a gas cassette that contains gas. Such a torch burner has a structure in which the gas in the gas cassette is taken inside, and the taken-in gas is subjected to a spark discharge using a piezoelectric material or the like to ignite the gas, and the flame. Is ejected from the nozzle.
This spark discharge is configured to be easily generated by a user operating a movable piece called a trigger disposed on the torch burner with a finger.
For this reason, it is extremely easy for the user to ignite simply by attaching the torch burner to the gas cassette, holding the torch burner with the gas introduced into the torch burner, and operating the trigger with the fingers of the gripped hand. Because it was able to be made, it became a very easy to use igniter.

However, when an adult uses such a torch burner, it may be easy to use, but when used by a child, a flame may easily be ejected from the nozzle, which may be dangerous.
Therefore, conventionally, a proposal has been made to arrange a safety device on a torch burner or the like so that a child cannot easily operate a trigger (for example, cited document 1).

US Pat. No. 6,840,759 (FIG. 3 etc.)

However, in fact, since a child easily releases such a safety device, a safety device that is difficult for a child to release is required. Of course, if the structure of the safety device is abnormally complicated, it becomes a safety device that is difficult for a child to release. However, this makes it difficult for an adult to release, and there is a problem that the torch burner becomes unusable.
Therefore, there has been a problem of developing a safety device that is easy to use for children while maintaining ease of use for adults.

  Therefore, an object of the present invention is to provide an igniter equipped with a safety mechanism that is easy to operate for adults and difficult for children to release.

  According to the present invention, the object is an igniter having a nozzle part for ejecting flame, a fuel introduction part for introducing fuel, and an ignition part for igniting the introduced fuel, wherein the ignition part is The ignition operation unit disposed on one side of the main body of the igniter is configured to ignite by moving to the ignition position, and the restriction unit that restricts the movement of the ignition operation unit to the ignition position and permits A movement restricting unit having a permission unit for the ignition operation unit, and the movement restricting unit moves the restricting unit or the permission unit in accordance with a movement direction of the ignition operation unit. The movement restricting portion operating portion that operates to move the movement restricting portion is disposed in a main body in the opposite direction on one side of the main body of the igniter, and the movement restricting portion includes the ignition The operation unit is ignited through the permission unit. The ignition operation unit has a maintenance unit for keeping the ignition position at the ignition position, and the maintenance unit is formed adjacent to or close to the permission unit along the movement direction of the movement restriction unit. Achieved by an igniter characterized in that

According to the said structure, the movement control part which has a control part which restrict | limits the movement to the ignition position of an ignition operation part, and the permission part for permitting is arrange | positioned with respect to an ignition operation part, and a movement control part moves. Thus, the restricting part or the permitting part can be arranged corresponding to the moving direction of the ignition operating part, and the movement restricting part operating part for operating the movement restricting part is provided on one side of the main body of the igniter. It is arranged on the body in the opposite direction.
For this reason, in order to move the ignition operation unit to the ignition position, the user of the igniter needs to move the movement restricting unit and align the permission unit with the ignition operation unit.
And in order to move this movement control part, it is the structure that it is necessary to operate a movement control operation part.
This movement regulation operation part is arrange | positioned among the main bodies of an igniter at the opposite side to the one side in which an ignition operation part is located. Therefore, the user who operates the igniter is configured to be required to simultaneously operate the movement restriction operation unit and the ignition operation unit that are disposed on the opposite sides of the main body.
Since such an operation is difficult to perform with one hand, the user needs to perform such an operation with both hands. This forces a very difficult operation for the child, and is therefore a safety mechanism that is difficult for the child to release.
On the other hand, since it can be operated by using both hands for an adult, the usability is maintained.

According to the said structure, the movement control part has a maintenance part for an ignition operation part to stop at the ignition position, when an ignition operation part moves to an ignition position via a permission part. For this reason, if the user arranges the ignition operation unit in the maintenance unit, the user can maintain the ignition state without continuing to operate the ignition operation unit.
In addition, since the maintenance unit is formed adjacent to or close to the permission unit along the movement direction of the movement restriction unit, the user can move the ignition operation unit from the permission unit to the maintenance unit by moving the movement restriction unit. It can be easily moved and arranged.

  Preferably, an ignition operation urging unit that applies an urging force to the ignition operation unit in a direction in which the ignition operation unit presses the maintenance unit is provided, and the permission unit and the maintenance unit include the permission This is achieved by an igniter characterized in that a maintenance part side stopper part for restricting the movement of the ignition operation part between the part and the maintenance part is formed.

According to the above-described configuration, the ignition operation unit is provided with the ignition operation urging unit that applies an urging force to the ignition operation unit in the direction in which the ignition operation unit presses the maintenance unit. Reliably maintained.
In addition, since the maintenance part side stopper part that restricts the movement of the ignition operation part between the permission part and the maintenance part is formed at the boundary part between the permission part and the maintenance part, the ignition operation part is mistakenly It is possible to reliably prevent the release from the maintenance unit.

  Preferably, the fuel is introduced into the ignition part by the movement of the ignition operation part close to the ignition position, and the introduction of the fuel to the ignition part is prevented by the movement away from the ignition position of the ignition operation part. The movement restricting portion has a movement restricting urging portion, and the urging force works so that the movement restricting portion moves along a direction from the maintaining portion toward the permission portion. The permission section is an opening that allows the ignition operation section to move from a position away from the movement restriction section to the ignition position, and the maintenance section side stopper section is separated from the separation section. It is a projection part which protrudes in the direction which goes to the said ignition position side from a position, It is an ignition device characterized by the above-mentioned.

According to the above configuration, the fuel is introduced into the ignition unit by the movement of the ignition operation unit close to the ignition position, and the introduction of the fuel to the ignition unit is prevented by the movement away from the ignition position of the ignition operation unit. The movement restriction unit has a movement restriction urging unit, and the movement restriction unit has a configuration in which the urging force works so as to move along the direction from the maintenance unit to the permission unit. The opening is an opening that allows the ignition operation unit to move from the separation position from the movement restricting section to the ignition position, and the maintenance section side stopper projects in the direction from the separation position toward the ignition position. It is a projection part to do.
For this reason, the ignition operation unit is relatively configured to apply a biasing force so as to move from the maintenance unit toward the permission unit.
When the user moves the ignition operation unit in the direction from the separated position toward the ignition position against the urging force of the ignition operation urging unit, the ignition operation unit gets over the protrusion. At that time, the movement restricting portion is moved by the movement restricting biasing portion along the direction from the maintaining portion to the permitting portion, whereby the ignition operation portion is moved from the maintaining portion to the opening side, and the opening portion is moved. To the non-ignition position, the introduction of fuel to the ignition part is blocked and the fire is automatically extinguished.
Therefore, the user can quickly and easily and safely shift from the ignition state to the fire extinguishing state only by operating the ignition operation unit.

  The present invention has an advantage that it is possible to provide an igniter equipped with a safety mechanism that is easy for an adult to operate and difficult for a child to release.

Preferred embodiments of the present invention will be described below in detail with reference to the accompanying drawings.
The embodiments described below are preferred specific examples of the present invention, and thus various technically preferable limitations are given. However, the scope of the present invention is particularly limited in the following description. Unless otherwise stated, the present invention is not limited to these embodiments.

FIG. 1 is a schematic perspective view showing, for example, a torch burner 1 which is an igniter of the present invention. As shown in FIG. 1, the torch burner 1 includes a nozzle 2 made of metal such as stainless steel and a torch burner main body 3 which are nozzles for ejecting flame.
Below the torch burner body 3, for example, a cassette attachment port 3 a that is a fuel introduction part for attaching a cassette (for example, gas) that is a fuel (not shown) is formed.
That is, the torch burner main body 3 is configured such that the gas can be introduced into the torch burner main body 3 by attaching a cassette containing gas to the cassette attachment port 3a.
As shown in FIG. 1, the torch burner main body 3 is provided with a gas adjusting knob 4 for adjusting the amount of gas introduced into the torch burner 3 from the cassette. In addition, the torch burner body 3 also has, for example, a trigger 5 that is an ignition operation unit that permits the introduction of gas into the torch burner body 3 and operates an ignition unit that ignites the introduced gas. .
Furthermore, for example, a safety lever 6 which is a movement restricting unit operating unit described later is also provided.
FIG. 2 is a schematic left side view of the torch burner 1 of FIG. 1. As shown in FIG. 2, the safety lever 6 has a horizontally long elliptical shape that is easy for the user to operate. .

FIG. 3 is a schematic view showing a state where a resin surface cover is removed on the back side of the torch burner 1 of FIG.
As shown in FIG. 3, a mechanism body 3 b into which gas is introduced is disposed inside the torch burner body 3. Moreover, the ignition part main body 7a is arrange | positioned at the nozzle 2 side of the mechanism main body 3b. An electrode is disposed on the ignition part main body 7a, and a spark discharge is generated between the electrodes. Gas is ignited by the spark, and a flame is ejected from the nozzle 2.
Further, the spark discharge of the ignition body 7a is generated by hitting the piezoelectric body in the ignition switch 7b of FIG. Specifically, the trigger 5 in FIG. 1 moves in the direction of arrow A in FIG. 3 to push the switch tip 7c, thereby hitting the piezoelectric body in the ignition switch 7b and causing a spark discharge in the ignition body 7a. The resulting configuration.
The ignition part 7 is constituted by the ignition part main body 7a, the ignition switch 7b, the switch tip part 7c, and the like. The position where the trigger 5 pushes the switch tip 7c and hits the piezoelectric body in the ignition switch 7b is an example of the ignition position.

Next, the gas flow in the torch burner body 3 of the torch burner 1 and its control mechanism will be described.
4 is a schematic view showing a main configuration in the mechanism main body 3b of FIG. 3, and FIG. 5 is a schematic enlarged view showing a portion indicated by an arrow B in FIG.
4 and 5 show a state where the gas control knob 4 is closed and the gas introduced from the cassette does not flow to the nozzle 2 side. Details will be described below.
As shown in FIG. 4, the mechanism main body 3 b has a first check pin 8 that contacts the trigger 5 and is pressed by the trigger 5 in the direction of arrow A in FIG. 4. A diaphragm 9 is disposed on the right side of the first check pin 8 in the drawing, and a second check pin 10 is disposed on the right side thereof. As shown in the figure, the second check pin 10 has a substantially T-shape arranged sideways.
Further, as shown in FIGS. 4 and 5, an O (O) ring 11 is arranged on the second check pin 10, and a spring 12 is arranged on the right side of the second check pin 10. Has been.

  Therefore, even if gas is introduced from the cassette into the torch burner 1 along the arrow C in FIG. 5, the gas is blocked by the O-ring 11 and the second check pin 10, and the gas passes through the nozzle 2. The configuration is not introduced to the side.

On the other hand, as shown in FIGS. 4 and 5, the spindle 13 is connected to the gas adjustment knob 4, and the spindle 13 moves in the direction of arrow D in FIG. 5 by the rotation of the gas adjustment knob 4. ing.
That is, when the gas adjustment knob 4 is turned in the closing direction, the spindle 13 moves in the lower left direction in FIG. 5 and moves in a direction to close the gas passage 14.
Therefore, in the state of FIG.4 and FIG.5, the gas from a cassette is the state interrupted | blocked completely.

FIG. 6 is a schematic enlarged view showing a state where the gas adjustment knob 4 of FIG. 5 is turned in the opening direction. In FIG. 6, the spindle 13 moves in the upper right direction in FIG. 6 along the arrow D in FIG. 6 in conjunction with the rotation of the gas adjustment knob 4. For this reason, as shown in FIG. 6, the gas passage 14 is opened and communicated with the nozzle 2 side.
However, since the positions of the second check pin 10 and the O-ring 11 are the same as those in FIG. 5, the gas in the cassette is not introduced to the nozzle 2 side.

FIG. 7 is a schematic view showing a state where the spindle 13 is at the same position as in FIG. 6 and the first check pin 8 is pressed by the trigger 5.
The first check pin 8 shown in FIG. 7 is pressed in the direction of arrow A by the trigger 5 shown in FIG. 4, so that the diaphragm 9 on the right side thereof is deformed so as to bend to the right side. Thereby, the second check pin 10 is also pushed to the right side, and when the pressing force exceeds the urging force of the spring 12, the second check pin 10 moves in the direction of arrow A.
Then, a gap is generated between the second check pin 10 and the O-ring 11, and the gas in the cassette is introduced along the arrow C to the gas passage 14 side. In the state of FIG. 7, as described above, since the gas passage 14 is in communication with the nozzle 2 side, the gas introduced into the gas passage 14 is introduced into the nozzle 2 side as it is.

Thus, in the torch burner 1 of the present embodiment, in order to introduce the gas to the nozzle 2 side, it is necessary not only to open the gas adjustment knob 4 but also to operate the trigger 5. It has a structure that takes into account.
Further, the amount of gas introduced into the nozzle 2 is adjusted by turning the gas adjustment knob 4 and changing the degree of opening (the position of the spindle in FIG. 7).

Next, the safety mechanism of the torch burner 1 will be described.
FIG. 8 is a schematic diagram showing the main configuration of the safety mechanism of the torch burner 1 of the present embodiment. FIG. 8 shows the trigger 5 shown in FIG. 4, the safety lever 6 shown in FIG. 1, etc., and a safety device 15 that is a movement restricting portion connected to the safety lever 6, for example.
As shown in FIG. 8, the safety device 15 has a substantially disk shape having an opening in the center portion, and a groove portion that connects the opening of the center portion and the outside is formed in the substantially disk-shaped portion. Yes.
Further, a guide portion 5a shown in FIG. 4 is formed at the lower end portion of the trigger 5 in FIG. This guide part 5a is an example of an ignition operation part.
FIG. 9 is a schematic plan view showing the safety lever 6, the safety device 15, and the guide portion 5a of FIG.
In the torch burner 1 of the present embodiment, the safety device 15 is disposed between the trigger 5 and the mechanism body 3b in FIG. For this reason, the trigger 5 in FIG. 4 is configured to abut on the first check pin 8 via the safety device 15.
That is, the safety device 15 can prevent the trigger 5 from unnecessarily abutting against and pressing the first check pin 8.

Hereinafter, the configuration of the safety device 15 will be described in detail. As shown in FIGS. 8 and 9, the safety device 15 is formed with, for example, a groove portion 15 c that is a permission portion (opening portion) that allows the guide portion 5 a to pass therethrough. A restricting portion 15b that prevents passage is formed.
For this reason, even if the user operates the trigger 5 in FIG. 4 to move in the direction of arrow A, if the guide portion 5a does not pass through the groove portion 15c, the first check pin 8 in FIG. 4 is pressed. It is a configuration that can not be.
In the initial setting of the torch burner 1, the guide portion 5 a of the trigger 5 is disposed at a position corresponding to the restricting portion 15 b of the safety device 15 as shown in FIG. 9. Therefore, in a state where the safety device 15 is not moved, the trigger 5 is blocked by the safety device 15 and the first check pin 8 cannot be operated.

As shown in FIG. 9, the safety device 15 includes, for example, a spring 15 a that is a movement restriction urging unit, and the spring 15 a applies a biasing force in the direction of arrow E in FIG. 9. It has become.
Therefore, the safety device 15 is rotated in the direction of the arrow F by the user operating the safety lever 6 and rotating in the direction of the arrow F in FIG. 9 against the urging force of the spring 15a, When the user releases the safety lever 6, it is configured to return to the original position by the biasing force of the spring 15a.
That is, the user moves the safety lever 6 in the direction of arrow F in FIG. 9 and the groove portion 15c is disposed at a position corresponding to the guide portion 5a, so that the guide portion 5a is moved through the groove portion 15b for the first time. It passes through and can reach the first check pin 8 of FIG.
Thus, the safety device 15 has a configuration in which the restricting portion 15b or the groove portion 15c can be arranged corresponding to the moving direction of the guide portion 5a (the direction of arrow A in FIG. 9) by rotating.

Further, as shown in FIG. 9, the restricting portion 15b and the groove portion 15c of the safety device 15 are arranged corresponding to the moving direction of the guide portion 5a (the arrow direction in FIG. 9). It arrange | positions so that it may be pinched | interposed into the one control part 15b, 15b.
And, for example, at the end of the groove 15c side of the restricting portions 15b and 15b, which is the boundary between the groove 15c and the restricting portions 15b and 15b, for example, restricting portion side stoppers 15d and 15d, respectively. Is formed in a protruding shape.

Further, as shown in FIGS. 8 and 9, on the inner peripheral side (center side) of the right restricting portion 15b across the groove 15c of the safety device 15, as shown in FIGS. 15e is formed. The maintenance portion 15e enters the central portion side through the groove portion 15c, and the guide portion 5a (that is, the trigger 5) disposed at the ignition position that presses the first check pin 8 of FIG. 4 remains in that position. It is a part for maintaining.
Since the maintenance portion 15e is disposed adjacent to the groove portion 15c along the moving direction of the safety device 15 (directions indicated by arrows F and E), the guide portion 5a is easily maintained by the rotation of the safety device 15. It is the structure which can be arrange | positioned to the part 15e.

Further, as shown in FIG. 3, a check pin spring 16 is disposed on the first check pin 16. As shown in FIG. 4, when the trigger 5 presses the first check pin 8, the check pin spring 16 moves the trigger 5 in a direction opposite to the arrow A in FIG. 4 (a direction away from the check pin 8). An urging force is generated so as to be moved.
The check pin spring 16 is an example of an ignition operation biasing portion.
For this reason, in the state where the guide portion 5a is arranged in the maintenance portion 15e of FIG. 9, the guide portion 5a is configured to be pressed against the maintenance portion 15e by the check pin spring 16, and is stably arranged in the maintenance portion 15e. The ignition position can be maintained.

Further, in the present embodiment, for example, a maintenance portion side stopper 15f is formed on the groove portion 15c side of the maintenance portion 15e, which is a boundary portion between the maintenance portion 15e and the groove portion 15c. This maintenance part side stopper 15f is an example of a protruding part formed by protruding the guide part 5a along a direction (a direction toward the central part) from the position away from the safety device 15 toward the ignition position.
Thereby, the guide part 5a becomes a structure pressed more reliably against the maintenance part 15e, without dropping from the maintenance part 15e.

  Further, the guide portion 5a pressed against the maintenance portion 15e is added to the safety device 15 when the user operates the trigger 5 to move the guide portion 5a until the height of the maintenance portion side stopper 15f is exceeded. The pressing force of the trigger 5 is lost. For this reason, the safety device 15 starts to rotate in the direction of arrow E in FIG. 9 by the biasing force of the spring 15a. Then, the guide part 5a relatively changes its position and comes into contact with the contact part 15g connected to the groove part 15c in FIG. Then, the guide part 5a becomes a structure removed from an ignition position along the groove part 15c by the urging | biasing force of the spring 16 for check pins of FIG.

Further, the trigger 5 of the torch burner 1 of the present embodiment is moved in the direction of arrow A in FIG. 3 as shown in FIGS. 3 and 4, so that the switch tip of the first check pin 8 and the ignition part 7 is moved. The part 7c is pressed together.
For this reason, the first check pin 8 is pushed by a single operation of moving the trigger 5 in the direction of arrow A, gas is introduced into the torch burner 1, and at the same time, ignition is performed by pressing the switch tip 7c. It has a configuration that can.
On the other hand, when the trigger 5 is separated from the first check pin 8 and the switch tip 7c, the second check pin 10 and the like are returned to their original positions by the urging force of the spring 12 in FIG. The introduction of gas into 1 is blocked, and the flame injection of the torch burner 1 is stopped.

  Therefore, as described above, the torch burner 1 is automatically extinguished when the guide portion 5a is moved outward along the groove portion 15c by the biasing force of the check pin spring 16 of FIG. It has become.

The safety mechanism of the torch burner 1 is configured as described above. The operation of the safety mechanism will be described in detail below.
First, the operation of releasing the safety mechanism and igniting the torch burner 1 will be described.
A user of the torch burner 1 as shown in FIG. 1 turns the gas adjustment knob 4 to set the spindle 13 in the open state shown in FIG. Thereafter, the safety lever 6 in FIG. 1 is slid in the direction of arrow F in FIG. 9 against the urging force of the spring 15a. Then, the groove 15c of the safety device 15 in FIG. 9 is disposed at a position corresponding to the moving direction (arrow A direction) of the guide portion 5a of the trigger 5.
In this state, when the user moves the guide portion 5a of the trigger 5 in the direction of arrow A, the guide portion 5a passes through the groove portion 15c as shown in FIG. 1 check pin 8 and switch tip 7c are pressed and the torch burner 1 is ignited. FIG. 10 is a schematic view of a main part of the torch burner 1 showing a state where the safety mechanism is released.
At this time, since the guide portion 5a is in contact with the contact portion 15g arranged continuously with the groove portion 15c, even if the user releases his / her hand from the safety lever 6, the biasing force of the spring 15a is used. The safety device 15 can be prevented from rotating in the direction of the arrow E and returning to the original position, so that it is easy to use for the user.

On the other hand, when the user does not slide the safety lever 6 and moves the trigger 5 in the direction of arrow A in FIG. 4, the state shown in FIG. 11 is obtained.
FIG. 11 is a schematic view showing a state where the safety mechanism of the safety device 15 is operating.
As shown in FIG. 11, in this case, the guide portion 5 a abuts on the restriction portion 15 b of the safety device 15, and the movement of the trigger 5 is stopped to prevent the movement, and the first check shown in FIG. 3 is performed. The pin 8 and the switch tip 7c are not pressed, and the torch burner 1 is not ignited.
Thus, in the present embodiment, the user slides the safety device 15 against the urging force of the safety device 15 on which the urging force works, and at the point where the safety mechanism is released, If the rotation of the safety device 15 is stopped and the trigger 5 is not operated in this state, the safety mechanism is not released and the torch burner 1 cannot be ignited.

Further, the safety lever 6 and the trigger 5 for sliding the safety device 15 are arranged on the opposite side of the torch burner body 3 as shown in FIG. That is, the safety lever 6 is disposed at a position opposite to the trigger 5.
For this reason, it is necessary to simultaneously operate the trigger 5 arranged on the opposite side of the torch burner body 3 and the safety lever 6 to which the urging force is applied, and to adjust the safety lever 6 to a specific position. .
Therefore, it is difficult for the user to perform these operations with one hand, and it is necessary to operate with both hands.
This forces a very difficult operation for the child, and is therefore a safety mechanism that is difficult for the child to release.
On the other hand, since it is easy for an adult to operate with both hands, the usability is maintained.

Further, in the torch burner 1 of the present embodiment, in the state shown in FIG. 11, even if the safety mechanism is to be released and the safety lever 6 is slid while the trigger 5 is pulled, the guide portion 5 a The movement is prevented by the stopper 15d, and the safety mechanism cannot be released.
As described above, in the present embodiment, the safety lever 15 must be operated to accurately place the safety device 15 at a specific position. Once the safety device 15 is placed at an incorrect position, the safety mechanism is released. Since it cannot be configured, the mechanism is extremely safe.

FIG. 12 is another schematic diagram showing a state in which the safety mechanism of the safety device 15 is operating.
FIG. 12 is an example in which the position of the groove portion 15c of the safety device 15 cannot be arranged corresponding to the position of the guide portion 5a, as in FIG. 11. FIG. 12 is different from FIG. The example which the guide part 5a contact | abutted to the control part 15b (right side in FIG.11 and FIG.12) is shown.
Also in this case, the guide portion 5a is blocked by the restriction portion 15b and the safety mechanism is not released, and the guide portion 5a abuts against the restriction portion side stopper 15d and the safety mechanism cannot be released while pulling the trigger 5. It has become.

FIG. 13 is a schematic view showing a state in which the guide portion 5a arranged at the ignition position is maintained in the ignition position as shown in FIG.
Specifically, the user slides the safety lever 6 and moves the safety device 15 in the direction of the arrow F in a state where the guide portion 5a is disposed at the ignition position in FIG.
Then, the guide part 5a is arrange | positioned at the maintenance part 15e beyond the maintenance part side stopper 15f. In this state, when the user stops the operation of the trigger 5 and releases the finger or the like, the guide portion 5a is pressed against the maintaining portion 15e by the urging force of the check spring 16 in FIG.
Further, even if the user removes his / her hand from the safe lever 6 and the safety device 15 tries to return in the direction of arrow E in FIG. 13 by the urging force of the spring 15a, the guide portion 5a has the retaining portion side stopper 15f. The torch burner 1 can maintain the state of the ignition position, and the torch burner 1 is easy to use for the user.

FIG. 14 is a schematic view showing an automatic fire extinguishing operation and the like of the torch burner 1. An arrow G in FIG. 14 indicates the movement locus of the guide portion 5a. Specifically, first, when the user intends to end the use of the torch burner 1 in the state where the guide unit 5a is arranged in the maintenance unit 15e of FIG. When 5 is pulled in the direction of arrow A, the guide part 5a arranged in the maintenance part 15e moves to the center part side of the safety device 15, and eventually reaches a position exceeding the maintenance part side stopper 15f. Then, the safety device 15 moves in the direction of arrow E by the biasing force of the spring 15a of the safety device 15, and the guide portion 5a contacts the contact portion 15g connected to the groove portion 15c. In this state, when the user releases his / her hand from the trigger 5, the guide portion 5 a moves in the direction opposite to the arrow A along the groove portion 15 c by the urging force of the check pin spring 16 of FIG. 3. As a result, the trigger 5 is disengaged from the position (ignition position) at which the first check pin 8 shown in FIG. 4 is pressed, so that the gas supply to the nozzle 2 side is inhibited and the fire is automatically extinguished.
In addition, as shown in FIG. 14, the guide part 5a is arrange | positioned at the control part 15b by the movement to the arrow E direction of the safety gear 15. As shown in FIG.

  As described above, in the torch burner 1 according to the present embodiment, after the user uses the torch burner 1, the trigger 5 can be automatically extinguished quickly and safely by pulling the trigger 5 once with a finger or the like and then releasing it. It can be configured.

As described above, in the torch burner 1 according to the present embodiment, the safety lever 6 disposed on one side of the torch burner main body 3 and biased by the spring 15a is operated, and the safety device 15 is disposed at a specific position. In addition, since it is necessary to simultaneously operate the triggers 5 arranged on the opposite side, it is difficult for a child to operate, and the mechanism is extremely safe.
