引力を増すように構成されている。 A yoke 5 made of a magnetic material and having an annular groove 13 open in the direction of the gas cylinder 1 is attached to the outer periphery of the socket 3. The groove edge 14 has a diameter that closely fits the flange 4 of the cylinder, and the center A passage hole 15 of the valve nozzle 2 is opened in the opening. Annular groove 13
The magnet 6 housed in the magnet 6 is formed in an annular shape and does not protrude beyond the groove edge 14, and is configured to form a magnetic circuit with the yoke 5 to increase the magnetic attraction force.

る。 Furthermore, this yoke 5 also serves as a guide for defining the gas cylinder position or set state, so that the guide protrusion 11 has a notch 16 that indicates the position of the siphon tube 8.
It is integrally attached to the upper end of the yoke so as to engage with the yoke. The yoke 5 also serves as a retaining cap for the operating valve 12 and O-link incorporated in the socket 3.

より成る。 The yoke 5 has a protrusion 17 protruding toward the cylinder side.
It has a spacer 7 on the inside or outside. This spacer 7 has a shape memorized at 60 to 70 degrees Celsius, which is set as a dangerous temperature, and has a flat ring shape at room temperature, but when the temperature exceeds 60 to 70 degrees Celsius, it deforms and creates unevenness 18 at the front and back, and the gas cylinder 1 The front surface A of the valve part 9 or the bottom surface B of the mountain cup 19
It is made of shape memory material that is shaped so that it can be pushed and retracted.

されている。 FIG. 3 shows an example in which a spacer that presses the cylinder flange 4 is fitted on the outside of the protruding part 17, and a holding part 19 consisting of a caulking projection or a claw is provided on the groove edge 14 to prevent the spacer 7 from coming off. FIG. 4 shows an example in which a spacer 7 that presses the end of the nozzle stem is fitted into the passage hole 15 and prevented from coming off by a seal member 20. Both spacers 7 are deformed at the set temperature and are held so that the unevenness 18 touches both surfaces A and B.

に磁気で止めるようにしても良い。 Note that the attraction force by the magnet 6 naturally needs to exceed the pressing force required to open the valve nozzle 2, and specifically, it is calculated by adding the spring load of the valve nozzle and the resistance from the O-ring that is in close contact for sealing. It is usually about 3 kgf. In addition, if the spacer 7 can be magnetically attracted, it may be held magnetically instead of the holding part 19 shown in FIG.

る。(Function of the invention) In the gas cylinder 1 with the above configuration, the valve nozzle 2 is connected to the socket 3, the guide protrusion 11 is engaged with the notch 16 of the cylinder flange 4, and the flange 4 is magnetically attracted to the yoke 5. is set. At this time, the valve nozzle 2 is opened, and the device can be ignited by operating the plug knob. If the ambient temperature reaches the set temperature due to abnormal handling during use,
The spacer 7 made of a shape memory alloy begins to deform and creates unevenness 18, pushing away the front surface A of the valve portion 9 or the bottom surface B of the mountain cup 19, creating a slight gap between the yoke 5 and the mountain cup 19, so that the magnetic attraction force is reduced. The gas decreases rapidly, the valve nozzle 2 protrudes due to the spring force, and the gas cylinder 1 comes off from the socket 3.

機構を要しないので軽く、生産性も向上する。(Effect of the invention) Therefore, according to the invention, the spacer 7 deforms due to an abnormal rise in the surrounding temperature and pulls the gas cylinder 1 away from the socket 3 or the yoke 5. Therefore, the valve nozzle 2 closes and the gas outflow stops at the same time. gas cylinder 1
The cylinder can be removed automatically and reliably, and it can be reinstalled once the temperature returns to room temperature.The structure is also simplified, and the complicated cylinder attachment/detachment mechanism required in the past is not required, making it lighter and easier to manufacture. Sexuality also improves.
