つた。Conventional Structure and Problems Conventionally, this type of liquid fuel combustion device sucks up liquid fuel by the capillary action of the lamp wick, vaporizes it from the tip, and burns it. A lamp wick 13 is mounted in a wick storage cylinder space 15 formed by a core storage cylinder 9 and an outer core storage cylinder 11 so as to be able to rise and fall freely, and an inner flame cylinder 4 in which a vaporizing part 13' at the tip of the lamp wick is arranged in a substantially concentric circle shape;
It burns by facing into the combustion chamber 8 formed between the outer flame tubes 5. In this case, the inner and outer flame tubes 9,
Reference numerals 11 are placed on the inner and outer flame pans 10 and 12 formed above the inner and outer core housing tubes 9 and 11, respectively, and during steady combustion, air holes provided in the inner and outer flame tubes 4 and 5 are installed. The lower portions of the inner and outer core housing tubes 9 and 11 had also become quite hot due to the flame formed in the tube 7 and heat conduction from the high temperature portions above. Therefore, wick 1
3 is lowered from the combustion position A to the position A' to extinguish the fire, the inner and outer core housing cylinders 9 and 1 will remain closed for a while.
Heat is received from the combustion chamber 8 to vaporize the fuel little by little, and this is combusted below the combustion chamber 8, so it takes a long time to extinguish the fire. In addition, even if the vibration extinguishing device is activated to instantly lower the wick and extinguish the fire when the combustion device is accidentally overturned, the wick is vaporized by the heat received from the inner and outer wick housing tubes 9 and 11. The fuel gas burns near the inner and outer fire pans 10 and 12, and the liquid fuel that leaks along the wick housing cylinder wall burns around the inner and outer fire pans 10 and 12.
Since it vaporizes around 12 and combusts here, it takes a considerable amount of time to completely extinguish the fire. Therefore, when a fire is extinguished, a large amount of unburned gas is generated, producing a strong odor, and when the fire is overturned, the flame remains for a long time, giving the user a sense of danger.

る。Structure of the Invention In order to achieve the above object, the present invention provides a vaporizing chamber in which the tip of the wick is exposed below the contact between the outer core housing tube and the combustion tube, and the wick side and outer core are housed below the vaporizing chamber. A small chamber is formed by an upper metal fitting attached to the wall of the outer core housing cylinder so that the upper wall of the cylinder does not come into direct contact, and a ventilation hole is formed in the outer core housing cylinder wall of this small chamber, and a step is created from this ventilation hole. An opening communicating with the core accommodating cylinder space is provided at the position. With this configuration, it is possible to lower the temperature at the bottom of the wick storage cylinder and avoid excessive temperature rise in the upper metal fitting.Furthermore, when extinguishing a fire, air is introduced from the opening through the communication port to instantly combust unburned gas. In addition, since the upper part of the wick storage cylinder is cooled by the inflow of air, the fire can be quickly extinguished and the odor generated during the extinguishment can be greatly suppressed. Furthermore, even in the event of a fall, the fire can be extinguished quickly, which is very effective in terms of safety. Furthermore, since the ventilation holes and openings are provided in a vertically leveled manner, it is possible to suppress the phenomenon of so-called flashback, in which vaporized gas leaks outside during normal combustion, ignites, and burns.

A small chamber wall 17 is formed above the outer core housing cylinder 11 with a stepped portion 16 interposed therebetween. 1
Reference numeral 8 denotes an upper metal fitting, which fits into the core-accommodating cylindrical space 15 of the small chamber wall 17.
It is attached to the side and forms a small chamber 19. The outer core housing cylinder 9 and the upper metal fitting 18 are made of stainless steel material.

第３図に示す如く長穴状としている。 In the above configuration, the small chamber 1 is formed by the small chamber wall 17 and the upper metal fitting 18 on the upper part of the outer core housing cylinder wall.
9 has an opening 20, so during normal combustion (when the tip of the wick 13 is in position B), the upper metal fitting 18
Although the upper metal fitting 18 is made of a separate member from the outer core housing cylinder 11, excessive temperature rise can be avoided. Therefore, heating of the side surface of the lamp wick 13 from the upper metal fitting 18 is suppressed to a minimum. Further, the heat of the upper metal fitting 18 is completely blocked by the opening 20. In addition, since a long hole-shaped ventilation hole 22 is provided above the chamber wall 17 to suppress heat conduction downward, the movement of heat downward is considerably suppressed, and the outer core housing cylinder 11 is kept at a relatively low temperature. It is maintained.
Therefore, when the lamp wick 13 is lowered to the B' position to extinguish the fire, vaporization of the fuel from the vaporizing section 13' is suppressed. The ventilation hole 22 has the role of introducing outside air and suppressing the downward movement of heat as described above, so it does not need to have a specific shape.
Although it can take any shape in consideration of the strength and combustion characteristics of the vicinity of the chamber wall 17, in this embodiment it is shaped like an elongated hole as shown in FIG.

物質の生成も減少するという効果が付加される。 In addition, since the opening 20 is located above the lowest position B' of the lamp wick, air is introduced from the opening 20 through the ventilation hole 22, so that the small amount of vaporized gas that is generated is quickly combusted, and the inflowing air causes the upper part to Since the temperature near the metal fitting 18 is cooled, combustion can be quickly stopped. Therefore, the fire can be completely extinguished in a short period of time without emitting a strong odor for a long time after the fire extinguishing operation. Furthermore, if the outer core housing cylinder 11 is made of stainless steel or the like having poor thermal conductivity, the transfer of heat to the lower part can be further suppressed, and the above effect will be further enhanced. When falling, there are the following effects. As in the case of fire extinguishing, the outer core storage cylinder 1
Since the temperature below 1 is maintained at a relatively low temperature, if the lamp wick 13 is tipped over and the vibration extinguishing device is activated to momentarily lower the lamp wick 13 to extinguish the fire, vaporization of fuel from the vaporization section 13' can be suppressed. A small portion of the generated fuel gas passes through the opening 20 and is quickly released from the vent hole 22 as shown in FIG. Further, the fuel gas remaining in the core housing cylinder space 5 is quickly combusted by the air introduced from the vent hole 22 through the opening 20 as shown in Fig. Since the fuel is quickly cooled, combustion can be stopped quickly. Furthermore, since the outer core housing cylinder has a relatively low temperature, the viscosity of the fuel does not decrease much. Therefore, the amount of fuel that flows out along the outer core housing cylindrical wall 11 when falling is small, and even if it does flow out, it is introduced into the small chamber 19 through the opening 20 and the fuel flows through the small chamber wall 1.
7, and there is no phenomenon in which spilled fuel evaporates and burns at the top, which is the case in the past. As described above, even in the event of a fall, the fire can be completely extinguished in a short time. Furthermore, the following effects can be seen during normal combustion. The opening 20 of the upper metal fitting 18 suppresses the movement of heat downward. Therefore, the temperature in this part is higher than in other parts, and the vaporized fuel gas does not condense.
Tar-like substances are also difficult to generate. This effect is further enhanced by using a material with poor thermal conductivity, such as stainless steel, for the upper metal fitting 18. Upper metal fitting 1
The inner diameter of the core accommodating cylinder space 15 side of 8 is the outer core accommodating cylinder 11
The inner diameter may be approximately the same as the inner diameter of the inner diameter, or the diameter may be slightly larger. If the diameters are almost the same, the wick housing cylinder space 15 is closed by the wick 13 during normal combustion, and fuel vaporized from the side of the wick 13 due to the heat of the upper metal fitting 18 may accumulate near the opening 20. However, since the opening 20 is located below the small chamber 19 and the ventilation hole 22 is located above the small chamber 19, and there is a level difference between the two, the accumulated gas stays only near the opening 20, so it leaks outside through the ventilation hole 22. , the phenomenon of ignition and combustion, the so-called backfire, is not observed. If the inner diameter of the upper metal fitting 18 is larger than the inner diameter of the outer core housing cylinder 11, a gap will be created between the lamp wick 13 and the upper metal fitting 18, and air will pass through the opening 20 from the ventilation hole 22.
Since the fuel gas is introduced into the combustion chamber 8 through the gap, there is no possibility of accumulation near the opening 20, so there is no risk of backfire.
Since air can be introduced into the lower part of the combustion chamber 15, the fuel gas accumulated in the lower part of the combustion chamber 15 is transported upward, which has the effect of preventing dew condensation in the lower part of the combustion chamber and reducing the generation of tar-like substances. will be added.

上させることが可能である。 Additionally, since the upper metal fitting 18 has an opening 20, it becomes hot, but since it is a separate member from the outer core housing tube, excessive temperature rise can be avoided, and heating of the side of the lamp wick can be kept to a minimum. In addition, if the inner diameter of the upper metal fitting 18 is larger than the inner diameter of the outer core housing tube 11, there is no direct contact between the lamp wick 13 and the upper metal fitting 18, and the side surface of the lamp wick 13 is kept at a relatively low temperature. Therefore, at the same time as the extinguishing, the side temperature of the lamp wick 13 quickly decreases and the extinguishing occurs. Also, there is less odor generated due to vaporization due to excessive heating.
Further, the lower end edge 21 of the upper metal fitting 18 is connected to the core housing cylinder space 1.
The wick 13 is slightly bent to increase the width of the wick 13, so that when the wick 13 is raised, the vaporizer 1
The lamp wick 13 is designed so that the lamp wick 13 can be raised and lowered smoothly at all times without the tip 3' getting stuck on the lower edge 21 and damaging the tip. In the above embodiment, only the case where a small chamber is provided on the upper part of the outer core housing cylinder wall is described, but conversely, the case where a small chamber is provided on the upper part of the inner core housing cylinder wall and the small chamber is provided on the upper part of both the inner and outer core housing cylinder walls is described. Even if it is provided, the same or better effect can be obtained. In addition, in the case where a small chamber is provided in either the inner or outer wick storage tube, a through hole 23 is provided in the upper part of the wick storage tube wall where the small chamber is not provided so that when the wick 13 descends, air is introduced into the wick storage tube space.

こで燃焼するということはない。(3) In the event of a fall, etc., the temperature near the lowest point of the wick is relatively low, so the viscosity of the fuel does not decrease much, and the amount of fuel flowing out along the wick housing cylinder wall is suppressed, and the amount of fuel flowing out is reduced. Since the fuel is led into the chamber through the opening, it will not flow out to the vicinity of the fire pan and burn there.
