- Fig. 9 shows that the safety device is when the portable heat transfer device is started, and the temperature of the heat collecting container 38 is still low. Since the push rod 57 is in the raised position, the swing arm 84 is in a substantially horizontal state. Therefore, the cam 93 pushes the valve body 88 toward the valve seat to close the safety valve. When the operation lever 56 is pushed down, the push rod 57 is also lowered against the action of the panel 57 ', and the oil damper 58 is activated.

- FIG. 11 shows an embodiment of a vaporizer used in the present invention.
- the portable heat transfer device of the present invention can be miniaturized and can be used for various applications.
- the cylinder when using the LPG cylinder as a gas supply source, the cylinder is inclined or inverted. When this occurs, liquid LPG may come out of the cylinder and reach the gas nozzle 36 (see Fig. 3). In this case, the mixing ratio of gas and air becomes extremely high, and combustion is incomplete and unstable. To prevent this, in this example, a part of the combustion heat is used to warm the vaporizer. By doing so, we are trying to forcibly vaporize LPG.
- This vaporizer is preferably installed between the gas cylinder in the gas flow path and the pressure regulator, as long as it can be maintained at a temperature 20-30 ° C higher than the LPG temperature.

- the check valve is formed while pressed against the O-ring 104, but the valve 102 opens due to the pressure difference and the LPG enters the main body 101. Since the main body receives heat from below and is about 20 ° C hotter than LPG, LPG vaporizes immediately. At this time, the vapor pressure in the main body 101 increases as the temperature increases by 20 ° C., and the check valve returns to the original position and the inflow of liquid LPG stops.
- the power from the outside 101 also becomes the second gas cylinder, and the arrangement on the left side Gas is supplied to the pressure regulator through tube 105.
- the pressure in the main body 101 gradually decreases, and when the vapor pressure is lower than the cylinder vapor pressure, the check valve opens again and a small amount of liquid LPG flows in. Since the LPG is repeatedly supplied while being vaporized, the pressure of the gas sent from the pipe 105 fluctuates.
- a pressure regulator is arranged on the downstream side, the gas can be supplied to the gas nozzle at a constant pressure. In the illustrated example, the force that slightly protrudes the base of the pipe 105 corresponding to the outlet side into the main body is for trapping liquid LPG that has entered the inside.

That is, when the vaporizer main body 101 is fixed to the outside of the valve tube 37 and the legs 101a extending from the lower side are provided up to the vicinity of the heat collecting container 38 and heated using the heat dissipated from the heat collecting container 38. good.
- FIG. 12 shows a main part of the seventh embodiment of the present invention.
- Combustion inside the device like a portable heat transfer device, requires an ignition discharge electrode in the combustion chamber, but this example shows another example of this electrode installation. is there.
- the piezoelectric element 64 is also depressed by the lever.
- the piezoelectric element 64 is built in a holder 112 made of an electrical insulator, and is configured to move up and down together with the discharge electrode 111, and is pushed upward by the panel 113.
- the tip of the discharge electrode 111 is contained in the flame hole 114 of the combustor.
- the repulsive force of the panel 113 is set to be weaker than that of the panel (not shown) inside the piezoelectric element. Therefore, when the operation lever 56 is first lowered, the holder 112 is lowered downward, and then the discharge electrode 111 is also exposed to the flame hole surface.
- the discharge electrode 111 when the discharge electrode is arranged in the upstream direction of the flame, the discharge electrode 111 is in a reducing atmosphere during the operation of the combustor and is less susceptible to acid and so the life can be extended. The Furthermore, deterioration by combustion heat is remarkably reduced by retracting the discharge electrode 111. In addition, the discharge electrode 111 can also stabilize the flame surface without disturbing the flow of the air-fuel mixture.
- the lead wire 116 is for guiding the electricity from the piezoelectric element 64 to the discharge electrode 111
- the seal brush 117 is a rubber seal for preventing the air-fuel mixture in the diff user from leaking.
- the insulating tube 118 is for preventing the discharge electrode 111 from causing unnecessary discharge in the middle.
