A spring 79 is stretched between the other end of the support plate 76 and the connecting strip 78.
The interlocking lever 29 is urged upward, that is, counterclockwise in the figure, through the interlocking lever 29.

Next, the operation will be explained. In the combustion standby state, the operating lever 28 and the interlocking lever 29 are each tilted upward about the connecting tube 25, and the lamp wick 5 is located at the lower end of the wick guide tube 3.
From this state, when the ignition operation plate 35 is pushed down via the knob 37, the interlocking lever 29 rotates clockwise about the connecting tube 25 against the spring 79. At this time, the operation lever 28 is connected to the ignition operation plate 35.
is pushed down by a pin 39 provided on the back surface of the lever, and rotates integrally with the interlocking lever 29. With this rotation, the engagement pin 50 of the operating lever 28 first comes into contact with the introduction part 49 of the adjustment lever 43, and this contact pushes the adjustment lever 43 leftward against the spring 48, and this operation The engagement pin 50 passes through the introduction part 49, and after this passage, the adjustment lever 4
3 moves back to the right by the biasing force of the spring 48, and the engagement pin engages with the engagement groove 46. After this engagement, the engagement pin 50 further descends, and this descent causes the adjustment lever 43 to rotate counterclockwise about the support pin 45, and the firepower operation plate 36 moves to the connecting lever 42.
is pushed up through the As the operating lever 28 rotates, the operating shaft 15 also rotates together, and the wick 5 is pulled up together with the wick holder 6 via the interlocking body 16, so that the wick 5 projects into the fire pan 11. With the operating lever 28 pushed down to the lowest position, the lamp wick 5 is held at the highest ignition position. The rotation of the interlocking lever 29 causes the other end of the transmission lever 75 to be pulled down via the connection strip 78, and the one end to be raised. Due to this rise, the ignition lever 64 rotates about the shaft 65 against the spring 67, and with this rotation, the push-up lever 69 rises, and the combustion cylinder 12 is pushed up using its one end as a fulcrum. The periphery of the wick 5 in the part that is inclined and faces the ignition heater 66 is open. As the ignition lever 64 rotates, the lever 64 contacts the electrode plate 73 and the ignition heater 66 is energized, and the heater 66 contacts the lamp wick 5 through the open portion, and this contact causes the lamp wick to 5.
Ignition for is achieved. When the operation lever 28 rotates, the locking lever 31 also rotates, and the hook-shaped locking portion 32 at one end of the locking lever 31 engages with the locking receiving portion 56 of the vibration detection arm 53 of the fire extinguishing mechanism. Make temporary contact and pass through.

After the lamp wick 5 is ignited, the operator releases the ignition operation plate 35, and this release causes the interlocking lever 29 to rotate counterclockwise due to the biasing force of the spring 79, returning to its original position. Return.
In addition, in response to this, the ignition lever 64 and push-up lever 69 are returned to their initial positions by the biasing force of the spring 67, and the combustion tube 12 is pulled down and placed in the fire pan 11. As the interlocking lever 29 rotates back, the operating lever 28 and the locking lever 31 also rotate counterclockwise due to the biasing force of the spring 34, but immediately after this rotation, the locking portion 32 of the locking lever 31 closes. It is locked to the locking receiver 56 of the fire extinguishing mechanism, and therefore the amount of rotation of the operating lever 28 and the locking lever 31 is suppressed to a very small amount. In conjunction with the rotation, the lamp wick 5 is slightly lowered from the ignition position, and is set at the combustion position with high firepower. Therefore, if left as is, high-power combustion will continue.

On the other hand, when setting the combustion thermal power to another medium or low thermal power, the user presses down the thermal power operation plate 36 to do so. That is, when the firepower operation plate 36 is pushed down via the knob 38, the operation is transmitted to the adjustment lever 43 via the connecting lever 42, and this adjustment lever 43 rotates counterclockwise about the support pin 45 as a fulcrum. The adjustment lever 43 is connected to the operation lever 28 by engagement between the engagement groove 46 and the engagement pin 50, and therefore, the operation lever 28 rotates counterclockwise in conjunction with the adjustment lever 43. The clockwise movement of the operating lever 28 is regulated by the bent piece 33 of the locking lever 31, but the counterclockwise movement is not regulated at all, so the operating lever 28 cannot be adjusted. It rotates freely in conjunction with the lever 43. This rotation causes the wick 5 to be lowered from the high power combustion position to the medium or low power combustion position depending on the amount of depression of the fire power control plate 36, thereby continuing the combustion state at the set fire power. In addition, when the combustion state is to be set to high heat power again, the fire power operation plate 36 is pushed up.

By the way, after ignition is achieved, the combustion tube 12 that is pulled down into the fire pan 11 is operated while being supported by the push-up lever 69. One end of the push-up lever 69 is rotatably connected to a bracket 68 of the ignition lever 64, so that the combustion tube 12
does not move while being restricted by the operation of the ignition lever 64, but is pulled down in a state where it can move freely via the push-up lever 69 that rotates around the shaft 70, and therefore the combustion tube 12 and the fire pan Even if the part 11 is distorted and deformed, the combustion tube 12 moves in accordance with the deformation and is placed in the fire pan part 11 in an accurately stable state. In other words, the combustion tube 12 fits into the fire pan 11 and is fixed.

Next, extinguishing will be explained. Combustion is extinguished by pushing down the knob 62 of the manual extinguishing lever 61. When the knob 62 is pressed down, the manual fire extinguishing lever 6
1 rotates, and the vibration detection arm 53 is rotated clockwise about the pin 54 against the spring 57. This rotation causes the lock receiver 56 to disengage from the lock portion 32 of the lock lever 31, and this separation causes the lock lever 31 to rotate counterclockwise by the elastic force of the spring 34. At this time, since the bent piece 33 of the locking lever 31 abuts against the lower edge of the operating lever 28, the operating lever 28 also rotates counterclockwise together with the locking lever 31. The engagement pin 50 of the operating lever 28 is engaged with the engagement groove 46 of the adjustment lever 43, but is disengaged from the engagement groove 46 by the rotational force of the operating lever 28. By rotating the operating lever 28 in the counterclockwise direction, the lamp wick 5 is pulled down at once and greatly via the interlocking body 16, thereby achieving instantaneous extinguishment.

When an earthquake occurs during combustion and the seismic pendulum 52 tilts, the disk 60 of the pendulum 52 causes the vibration detection arm 5 to
3 is rotated, so even in the event of such an earthquake, the fire can be instantly extinguished and safety can be ensured.

[Effect of idea]

As explained above, according to the present invention, the wick is raised to the ignition position with only one operation of pushing down the interlocking lever, and by moving the operating lever up and down at this position, the wick is moved up and down to adjust the firepower. Therefore, compared to the conventional case where the operation dial is rotated frequently, the work is easier and more efficient, and the usability is greatly improved.
