Definitions

• the present invention relates to a combustion nozzle of a gas lighter, particularly, to a structure of a nozzle having an automatic fire extinguishing device inside, which is more efficient for mass production. In addition, it proposes a cost-effective structure.
• Fig. 3 is a partial view of the filer and igniter igniter near the fuel valve, with the automatic fire extinguisher installed inside the nozzle rod. Is shown.
• Fig. 4 and Fig. 5 show the state in which an automatic fire extinguishing device is incorporated in a valve rod (nozzle cylinder), which was used for the proposal we have already made. It is a diagram. Since the combustion valve has been described so far, it will be briefly described.
• Fig. 3 shows a file of a file of pyrotechnics, with no flame length adjustment ⁇ .0 type.
• 1 is the fuel tank
• 1a is the upper wall of the tank
• 1a is the inside of the tank.
• the gas is regulated by the flow regulating member 2 and flows out of the through hole 3, but when not in use, it is springed (not shown in Fig. 5).
• the valve 4 (first valve) closes the through-hole 3 due to the repulsive force of (1), and is closed.
• Ignition stone 1 1 is always attached to file 10 by stone pushing spring 12
• the user rotates the file, it is pressed and is shaved while being heated, and scatters as sparks above the gas outlet 5a. .
• the user pushes down one end of the gas valve opening lever 9 (this part is omitted in FIG. 3 for 5 minutes), so that the other end holds the stick 5.
• Lift valve 4 is opened. The gas flows around the valve rod through the through hole 3, enters the inside through the lateral hole 5b, and further exits through the vent hole 5a. At this time, it is ignited by the above-mentioned spark and creates a flame.
• the 0 ring 7 is located between the tank wall and the rod by the cap 8 and prevents gas from leaking out of the circumference of the rod during use. I am coming.
• the shape memory alloy coil 14 and the valve 13 (the second valve) are installed as an automatic fire extinguishing device inside the valve stick 5, and abnormal continuous combustion occurs. When the temperature of the spill valve rises, the alloy coil 14 extends and pushes the valve 13 against the lower end of the orifice 5a to stop the gas flow, so that the flame is immediately extinguished. Be safe by fire. 15 is a return spring for restoration.
• Figures 4 and 5 show examples of automatic fire extinguishing devices using a shape memory alloy coil inside a nozzle rod, which we have already proposed. It is.
• a bottom plug 6 holding an elastic valve 4 is press-fitted to the lower end of a valve rod 5.
• the conventional rod assembly is two parts, a rod and a valve, but is increased by four parts to six parts. (Training the shape memory alloy coil If it is made bidirectional, the return spring is not required and the number of parts increases.)
• Fig. 4 shows an example in which the return spring is used because the valve movement by the alloy coil locks the lower end and moves upward.
• Fig. 5 shows an example in which the upper end is locked, the valve moves downward, and the return spring is not used. 'The direction of movement of the valve and the presence or absence of the return spring can be arbitrarily selected. Section ⁇ 1 where the idea is going to be solved
• valve 4a in consideration of the shape of the valve 4 (first valve, commonly known as valve rubber) originally possessed by the gas lighter, and At the end, an alloy coil 14 is press-fitted and locked.
• a valve 13 second valve
• a return spring 15 and a subassembly are added. Then, we propose a structure that completes the automatic fire-extinguishing nozzle by incorporating this into the stick 5. Action
• valve rubber is an essential part by nature, so the increase in the number of parts requires alloy coiling, valve (second valve) and return. Only three points of the spring are required, and the processing of the gas passage on the stick is not required. (If the combined coil is a two-way coil, the number of parts is 0 (addition is only required at 2 points).
• Valve rubber (first valve) ⁇ Alloy coil and valve (second valve)
• a sub-assembly with a return spring may be added, and this may be incorporated into the rod.
• the method is reasonable and procedural in terms of work, and is advantageous for manual work as well as for automated mechanization, with the result that it is easy to use with a minimum number of parts.
• a repeatable and automatic firefighting nozzle has been completed and will be of great benefit to its purpose.
• FIG. 1 and FIG. 2 are shown as examples.
• FIG. 1A is a perspective view illustrating the incorporation. Return to the sticker nozzle and spring (unnecessary if the alloy coil is bidirectional), combined with the second valve, alloy coil ⁇ , the first valve The arrow indicates that it should be incorporated. FIG. 1 is a cross-sectional view showing a completed state.
• Fig. 2 shows the main cylinder part 5 'incorporating an automatic fire extinguishing device and a heat collecting filter at the tip, not made as a single nozzle rod.
• An example is shown in which it is made as two parts of the spout hole 5 with a press-fitting and is press-fitted. The outer surface of the alloy coil is locked to the inner surface of the top of the valve 4.
• A is a perspective view explaining the assembly, and B is a completed sectional view.
• the nozzle 5C at the tip of the nozzle in the embodiment shown in FIG. 2 is to be operated reliably and promptly regardless of the attitude of the lighter (such as upright, inclined, or inverted). On the other hand, after extinguishing the flame, the heat dissipating fins and o also become available, which helps to shorten the restoration time.
• FIG. 1 and FIG. 2 have been presented and explained as embodiments, it is needless to say that there may be still different examples as a structure in accordance with the gist of the invention. Yes, and assembling procedures, depending on the detailed design and size of the parts, the parts of the automatic fire extinguishing system should not be assembled first, In some cases, it may be possible to obtain individual U. The effect of the invention
• an automatic fire-extinguishing nozzle for a gas-line and evening gas which can be repeated and repeated is the most suitable. Few additional parts
