The present invention relates to a portable safety gas container, and more particularly, when cooking using a portable gas stove, the temperature of the gas container is excessively increased due to heat transfer to the portable gas container mounted on the stove. The modified internal mechanism relates to a portable gas container which prevents the gas container from exploding by blocking the gas flow path so as to reduce or turn off the gas stove's thermal power.

In general, the portable gas container is a device that supplies gas to a cooking appliance such as a portable gas stove, which is used to easily bake meat or heat cooking utensils outdoors or indoors. Increasing range and safety accidents increase accordingly, and various safety devices are being developed to reduce the risk of accidents.

 In the case of such a portable gas stove, when gas is supplied from the gas container to the gas stove during cooking, the gas vaporizes and serves to lower the temperature of the gas container by the latent heat of evaporation, which takes away the heat of the surroundings. Concerns are low.

However, cooking utensils, such as a pan, pot, etc., which are wider than the gas stove placed on the upper part of the portable stove, are heated, and radiant heat generated from the lower part is transferred to the gas container. Heat is accumulated in the gas container by the difference between the radiant heat and the latent heat of evaporation, and the internal pressure of the gas container increases due to the gas expansion due to the temperature rise.

As described above, the radiant heat is continuously transferred to the gas container which is accommodated on one side of the gas stove to supply gas, and the temperature of the gas container is increased, and the internal pressure is increased to explode.

Therefore, in order to prevent the explosion risk as described above, the development of a safety device such as an automatic release device, an abnormal pressure discharge device, or a gas supply port of a gas container at a predetermined position on a portable gas stove has been developed. When a pressure rises above the allowable deformation pressure of a gas container, a container with a safety device that temporarily releases the gas inside the container to the outside of the container before the explosion is opened and developed has been developed and sold after obtaining a patent. In the case of a gas leak between the gas supply port and the safety device, the risk of explosion cannot be ruled out because it is close to the burner side where the thermal power is generated, and when the temperature of the gas stove body rises, the user can control the thermal power. There is a problem that must be done directly.

Accordingly, the present invention has been made to solve the above problems, the first object of the present invention is a gas container mounted on the gas stove for supplying gas, radiant heat transmitted from the burner side of the gas stove during cooking Therefore, when the temperature of the gas container rises or falls above a predetermined temperature, it is to provide a portable safety gas container that can control the amount of fire by controlling the gas supply by gradually opening and closing the supply port of the gas flow path.                         

In addition, the second object of the present invention is that when the gas container rises above a certain temperature due to the influence of the radiant heat and the external temperature due to the burner-side thermal power, the gas flow path inside the gas container is completely sealed, so that the fire of the gas stove burner Providing a portable safety gas container to prevent the explosion of the gas container by turning off.

2 shows a first embodiment of the present invention.

2, the first embodiment of the portable gas container 200 according to the present invention is a cylindrical gas container body 201 having a cap 220 is installed at the top so that the gas is stored therein and the inside thereof is sealed. And, the cap 220 is mounted so as to protrude upward from the center portion, the gas passage 251 is installed to extend in communication with the gas container body 201, and the gas passage 251 is installed on the spring 240 disposed in the lower portion The nozzle 210 which is operated up / down through the nozzle 210 and the nozzle 210 is formed on the nozzle 210, and when the nozzle 210 descends, the nozzle hole is opened to the gas flow path 250 to discharge the gas to the outside of the nozzle 210. 210a and the gas flow path 250 installed in the gas container body 201 are installed at a predetermined position so that the inside of the gas container body 201 is changed to a predetermined temperature, the supply port 252 of the gas flow path 250. It includes a safety device 300 to gradually open and close the.

The safety device 300 is fused to one side of the fixing piece 310 and the metal fixing piece 310 is installed to be fused or clip on the gas flow path 250 installed to communicate in the gas container body 201, When the temperature inside the gas container body 201 rises to a predetermined temperature, the shape is deformed in proportion to the temperature change to be bent toward the supply port 210a to sequentially seal the supply port 252. It is composed of a first opening and closing means 340.

In addition, the first opening and closing means 340 is mounted on one end of the first opening and closing means 340 is bent toward the supply port (210a), the first opening and closing means 340 to completely seal the supply port (210a) It is preferable that the formed sealing portion 330 of the elastic material formed of the heat-resistant and gas-resistant material formed therein and having the elastic body 331 of a predetermined shape be further mounted.

In addition, the first opening and closing means 340 is formed of a metal material, it is preferable that the bimetal bonded to the first and second metal pieces 370 and 345 having different thermal expansion coefficients.

In addition, the first opening and closing means 340 may be a shape memory alloy whose shape is deformed as the temperature in the gas container body 201 varies.

In addition, the first opening and closing means 340 may be a material that is deformed as the temperature is changed, the volume is contracted or expanded to open and close the supply port 252 of the gas flow path 250.

The bimetal, which is the first opening and closing means 340, has a low expansion of the first metal piece 370, and an alloy of nickel (Ni) and iron (Fe) is made of copper, and the second metal piece 345 of the large expansion side is made of copper ( It is made by joining using an alloy of Cu) and zinc (Zn), an alloy of nickel (Ni), manganese (Mn), iron (Fe), an alloy of manganese (Mn), nickel (Ni), copper (Cu), and the like. do.

That is, the first metal piece 370 and the first metal piece 370 made of a material having a small thermal expansion are bonded to a side close to the supply port 252 so as to be bent toward the supply port 252, and the first metal piece 370. The second metal piece 345 to be bent in the U shape is bonded to the fixing piece 310.

Referring to FIG. 2, when the temperature inside the gas container body 201 is below a predetermined temperature, the second metal piece 345 is unfolded in the direction of the arrow, and the first opening and closing means 340 is operated to be substantially horizontal.

Therefore, when mounted and used in the accommodating part 140 of the gas stove 100, the gas is normally supplied through the gas flow path 250.

As described above, when a fire is generated through the burner 110 by continuously supplying gas to the gas stove 100, the temperature of the gas container body 201 is increased due to the radiant heat of the gas stove 100. The temperature inside the body 201 is raised.

Referring to FIG. 3, in the above-described case, the coefficient of thermal expansion of the second metal piece 345 is relatively larger than that of the first metal piece 370, thereby making the first metal piece 370 bent in a U shape.

Therefore, in the process of rising to a predetermined temperature, the first opening and closing means 340, such as bimetal is sequentially bent toward the supply port 252 side, in the process of the first gas can flow to the burner 110 during the bending process As the area of the gas flow path 250 becomes smaller, the thermal power of the gas stove 100 is automatically weakened, and heat transmitted to the gas container body 201 is reduced. If the temperature of the gas container body 201 is no longer increased, the gas container body 201 may continue to be used as the thermal power of the state, and if the temperature of the gas container body 201 decreases with time, the first opening / closing means 340 may be used. The shape is deformed to open the supply port 252 of the gas flow path 250 so that the gas stove 100 can be normally used.

However, in spite of the above process, when the temperature inside the gas container body 201 rises to a predetermined temperature, the supply port 252 of the gas flow path 250 is provided at one end of the first opening / closing means 340. It is completely sealed by) to turn off the flame of the gas stove 100 to eliminate the effect of additional radiant heat and completely eliminate the cause of explosion of the gas container 200.

At this time, the user determines that the gas is exhausted and removes the used gas container body 201 from the accommodating part 140 of the gas stove 100 or turns off the light in the burner 110 of the gas stove 100. When the temperature inside the gas container body 201 is lowered, the first opening and closing means 340 is reverse to the above operation is horizontal, and the supply port 252 is opened.

At this time, while the first opening and closing means 340 is bent or extended by a variable temperature, the sealing part 330 installed at one end opens and closes the supply port 252 of the gas flow path 250.

Referring to FIG. 4, when the sealing part 330 formed of a heat resistant, gas resistant elastic member or the like closes or opens the supply port 252, the elastic body may adjust the gas flow by gradually opening and closing the supply port 252. 331 is formed in a shape that is in close contact with the supply port 252.

In addition, the elastic body 331 may be formed in a conical shape or semi-circular shape to gradually adjust the flow amount of the gas supplied to or blocked through the gas passage 250 to the sealing portion 330.

Therefore, when the temperature of the gas container body 201 sequentially rises, the first opening and closing means 340 such as bimetal causes the second metal piece 345 to bend the first metal piece 370, and thus the first opening and closing means ( 340, the elastic body 331 formed at one end is operated to gradually block the supply port 252.

Therefore, when the temperature rises to a predetermined temperature, the elastic body 331 is completely closed by being in close contact with the supply port 252. On the contrary, when the temperature inside the gas container body 201 decreases, the first opening / closing means 340. When the elastic body 331 that seals the supply port 252 is gradually separated from the supply port 252, the gas is gradually supplied.

On the other hand, although not shown in the drawings, after bonding the first opening and closing means 340 to one side of the fixing piece 310, when the first opening and closing means 340, such as the bimetal, is raised to a predetermined temperature, The inner opening of the gas container body 201 determines the first opening and closing means 340 to open and close the supply opening 252 based on a position at which one end of the first opening and closing means 340 is closed on the supply port 252 side. It may be fixed by fusion at the position.

5a and 5b show a second embodiment according to the invention.

Referring to FIG. 5A, a safety device installed in the gas container body 201 having the same configuration as that of the first embodiment is formed on the gas flow path 250 and is wider than the supply port 253 of the gas flow path 250. It is installed to have a space fixed to the fixed portion 370, the fixing groove 371 is formed on both sides, and the fixed groove 371 of the fixing portion 370 is deformed in accordance with the changing temperature in the gas container body 201 And the second opening and closing means 350 having a flat iron or disc shape installed to open and close the supply port 253 side.

The second opening and closing means 350 is made of a material such as bimetal or shape memory alloy that is bent downward as the temperature of the gas container body 201 rises, and the lower surface of the second opening and closing means 350 formed of this material is set to a temperature. As it changes to the supply port 253 is blocked.

Referring to FIG. 5B, when the temperature in the gas container body 201 is raised to an arbitrary temperature, the second opening and closing means 350 closes the supply port 253 and again the temperature in the gas container body 201 is lowered. In this case, while the second opening and closing means 350 returns to its original position, the supply port 253 is opened to supply gas to the space except for the second opening and closing means 350.

Therefore, when the temperature of the portable gas container 200 increases due to the radiant heat of the gas stove 100 during cooking, the thermal power may be weakened by reducing the amount of gas supplied, and when the temperature rises to a predetermined temperature, the gas supply may be stopped. Complete blocking will prevent the risk of personal injury or fire from explosion.

6 shows a third embodiment of the present invention.

In the second embodiment, even if the temperature in the gas container body 201 decreases, the manual return type third opening and closing means 360 which does not return to the original position may be used.

The third opening and closing means 360 is a material that blocks the supply port 253 when the temperature in the gas container body 201 rises, but does not return to the original state even when the temperature decreases.

Accordingly, when the gas container body 201 is removed from the gas range 100, the third opening and closing means is formed by the first and second wires 410.420 connected to the nozzle 210 that rises by the return force of the spring 240 that is pressed. 360 may be pulled in the opposite direction to be returned to open the supply port 253, and gas may be supplied to the space except for the disc-shaped third opening and closing means 360.

In addition, when the gas container body 201 is mounted on the housing 140 of the gas stove 100 as in the first and second embodiments, the temperature of the gas container body 201 is increased. The supply port 253 is gradually opened and closed as it varies, but the supply port 253 is closed due to the temperature rise of the thermal power formed in the burner 110 of the gas stove 100 in a state where the gas container body 201 is mounted. When the gas container body 201 is mounted without being removed from the gas stove 100 when the gas supply is turned off due to the interruption of the gas supply, the nozzle port 210a of the nozzle 210 remains open. The temperature in the gas container body 201 is lowered, the first, the second opening and closing means (340, 350) the supply port 252, 253 is automatically opened so that the gas is supplied through the gas flow path 250 Becomes

At this time, the possibility that a gas leaks through the nozzle 210 of the mounted gas container body 201 may cause a safety accident cannot be excluded.

Therefore, in the third embodiment, the material of the third opening and closing means 360 is bent when the temperature rises so that the lower surface of the third opening and closing means 360 seals the supply port 253, but returns to the original position even when the temperature is lowered again. Use a material that is not compatible.

Referring to FIG. 6, in a state in which the third opening and closing means 360 closes the supply port 253 as described above, even if the temperature in the gas container body 201 decreases, the third opening and closing means 360 returns to its original position. Will not be.

In the safety device according to the third embodiment, the bimetal, etc., which is deformed by the temperature and blocks the supply port 253, uses the third opening and closing means 360 made of a material which is never automatically returned even when the temperature decreases. The manual return means 400 additionally installed therein is connected to the lower end of the nozzle 210 and has a first wire 420 having a locking plate 421 formed at an end thereof, and a locking plate 421 of the first wire 420. It is composed of a guide square ring 410 installed to be inserted therein, and the second wire 423 connecting the lower end of the guide square ring 410 and the third opening and closing means 360.

Here, when the nozzle 210 is pressed while the gas container body 201 is mounted on the gas stove 100, the first wire 420 connected to the lower end of the nozzle 210 is formed at the bottom of the first wire 420. The stopping plate 421 moves downward within the guide square ring 410.

Therefore, the guide square ring 410 is not changed according to the operation of the nozzle 210, and the second wire 423 connecting the lower end of the guide square ring 410 and the third opening and closing means 360 does not operate. Do not.

However, in the above state, when the temperature in the gas container body 201 is raised by an external factor, the third opening and closing means 360 is deformed downward so that the lower surface of the third opening and closing means 360 is a supply port. Blocking 253 prevents gas from being supplied through the gas flow path 250 anymore.

On the other hand, in the above state, when the thermal power of the burner 110 is lost, the temperature in the gas container body 201 is lowered, at this time, the third opening and closing means 360 is blocked by the metallic characteristics and elasticity It maintains state and does not return automatically in any case.

At this time, in order to return the third opening and closing means 360 to the original position, the gas container body 201 is removed from the accommodating part 140 of the gas stove 100 and the nozzle 210 is returned upward by operating upward. This is because the nozzle 210 pulls the first wire 420 upwards, and the guide plate ring 410 is pulled up while the locking plate 421 of the first wire 420 is brought into contact with the upper surface of the guide ring 410. This rises, and accordingly, the third opening and closing means 360 connected to the second wire 423 fixed at the lower end of the guide square ring 410 is returned to its original position by receiving a pulling force upward.

Therefore, the nozzle 210 is in a state before the gas container body 201 is mounted, and the gas flow path 250 is opened while the third opening and closing means 360 is returned to its original position.

Therefore, even when the gas container body 201 is mounted on the gas stove 100, even if the thermal power is lost, even if the gas container body 201 is not removed, the gas in the gas container body 201 can be efficiently leaked. You can prevent it.

On the other hand, in the first and second opening and closing means 340 and 350 in the first and second embodiments, even if the temperature of the gas container body 201 decreases, the supply port 253 is provided by the raising operation of the nozzle 240. The manual return means 400 as in the third embodiment may be further provided to open and close.

According to the portable gas container having an explosion-proof function as described above, if the temperature inside the gas container rises abnormally, the gas flow path is completely blocked at a predetermined temperature at a predetermined temperature, but the gas flow path is completely blocked at a set temperature, but up to a set temperature. When the temperature rises, the shape change of the opening and closing means gradually increases, and at first, when the temperature rises, the gas supply port is narrowed and the gas supply amount is reduced to weaken the flame to suppress the temperature rise of the gas container, and the user knows the flame decrease and the container temperature is excessive. It is possible to recognize that it has risen rapidly, and if the condition is not understood or the temperature continues to rise, the gas flow path is completely shut off, thereby completely preventing the explosiveness of the portable gas container. There is a fundamentally preventable effect.
