The present invention relates to a gas can explosion-proof device for a portable gas stove having a diaphragm breakage prevention function, and more specifically, a structure for preventing a diaphragm breakage by a high-pressure gas supply and a configuration for coping with the explosion pressure higher than that. In this way, the device can be manufactured at low cost, and the simplified configuration ensures driving stability for each pressure.

The portable gas range is configured to store a gas can for supplying gas as already known, to combine a stored gas can with a gas injection device to supply gas, and to collect the collected gas from a mixing tube and collect the gas. Induced by the configuration to generate a flame through the burner head is formed is formed in the case to be the exterior.

Since the above-described portable gas cooker heats the cooking vessel on top of the burner head in which the flame is generated, the gas expands above a certain pressure inside the gas can due to radiant heat generated around the cooking vessel and the case during a long time use.

The pressure of is the pressure at which the gas can is removed from the gas inlet or cut off the supply of gas according to the law of the Gas Safety Corporation. Hereinafter, this pressure is described as dangerous pressure.

이상의 압력은, 상기 위험압력 상태에서 가스캔이 가스주입구에서 이탈거나, 가스공급이 차단된 상태에서 가스레인지의 주변에 잔여하는 복사열로 인해 가스캔 자체가 인장(길이방향으로 팽창)되고, 이에 따라 가스캔이 가스주입구에 다시 결합되어 가스캔이 변형됨에 따라 폭발예상되는 압력이다. 이하, 상기 압력을 변형임계압력이라 기재한다.2) 13

The above pressure may cause the gas can itself to be tensioned (expanded in the longitudinal direction) due to the radiant heat remaining around the gas range in the state where the gas can is released from the gas inlet under the dangerous pressure or the gas supply is blocked. The pressure that is expected to explode as the gas can is decoupled to the gas inlet and the gas can is deformed. Hereinafter, the pressure is referred to as strain critical pressure.

The above pressure may be caused by the fact that the gas injection reaches the explosion pressure above the dangerous pressure, or the radiant heat is cooled at the explosion pressure.

When the pressure reaches to the pressure of the high-pressure gas proceeds to the diaphragm side diaphragm is deformed or damaged to prevent the function to function. Hereinafter, the pressure is referred to as diaphragm breaking pressure.

In order to achieve the above another object, the present invention, the exhaust sound generating mechanism is provided in the passage through which the gas is exhausted to express that the gas is exhausted to the outside at the modified threshold pressure.

Hereinafter, embodiments of the present invention to which the above features are applied will be described in detail with reference to the accompanying drawings.

1 is an exploded perspective view of a gas injection mechanism to which the explosion prevention apparatus according to the present invention is applied; FIG.

Referring to the drawings, the gas injection mechanism 1 includes a housing 2 which is an exterior, a gas injection port 3 formed at one side of the housing 2, and a pressure of the gas that is formed at an upper portion of the housing 2. It is composed of a diaphragm (4) for adjusting and supplying.

The diaphragm 4 is usually formed of a rubber plate having excellent elasticity, and is formed as part of the valve device 6 for adjusting the pressure of the gas collected in the control chamber 5 through the gas inlet 3.

As shown in FIG.

The housing 2 is formed in such a way that the traveling path 2a, the branching progress path 2b, and the supply path 2c communicate with each other therein.

The flow passage 2a is in communication with the gas inlet 3 is supplied gas, the branch flow passage 2b is branched downward from the progress passage (2a) gas is injected, the supply passage (2c) ) Is formed such that gas flowing through the traveling path 2a is supplied to the diaphragm 4 side.

The can release drive unit 10 has a chamber 11 formed inside the housing 2 in communication with the branching path 2b, and the spring 12 that is the elastic body 12 and the elastic mechanism inside the chamber 11. 13 is coupled and installed, the sensitive body 12 is coupled so as to slide the inside of the chamber 11 is installed so that one side is protruded to the outside of the housing 2 by the supply of gas above the dangerous pressure. It is like.

The flow path intermittent portion 20 is a configuration to which the features of the present invention are applied, and is formed of an intermittent mechanism 30, an O-ring 40, a finish 50, and a spring 60 that is an elastic mechanism.

The interruption mechanism 30 is inserted into and coupled to the traveling path 2a of the housing 2 through which gas flows, and an injection path 31 for communicating the injected gas to the diaphragm 4 side is formed therein, and proceeds. It is installed to be movable in the furnace (2a).

The O-ring 40 is coupled to the outer surface of the control mechanism 30 (three in the figure) to form a communication section (S1) and the blocking section (S2).

The communication section S1 has a width for communicating the injection passage 31 with the diaphragm 4 at the normal pressure and exhausting the gas to the outside through the exhaust groove 2d formed in the traveling path 2a at the deformation threshold pressure. It is formed, it is a section formed on the right side of the drawing.

The blocking section S2 is formed to have a width for blocking gas traveling to the diaphragm 4 at the diaphragm breakage pressure and the deformation threshold pressure, and is a section formed on the left side of the drawing.

As shown in the exploded perspective view of FIG. 3, the finish body 50 has an exhaust hole 51 formed therein for guiding the gas exhausted through the exhaust grooves 2d to the outside at a deformation threshold pressure. It is coupled to the open end of 2a).

Here, the exhaust groove (2d) is formed at least one radial on the inner surface of the traveling path (2a), which is formed in a number suitable for various standards of the gas capacity and gas range through the gas injection mechanism (1).

In addition, the inlet for the gas flowing through the exhaust groove (2d) flows into the exhaust hole (51) when in contact with the control mechanism (30) at the deformation threshold pressure on the side of the control mechanism (30) side of the finish body 50 Grooves 52 are formed.

When the gas can is released from the gas inlet 3 by the driving of the gas can mounting lever, the supply of gas is once interrupted. At this time, when a high temperature radiant heat remains around the gas can, the gas can is expanded. It is tensioned and mounted again in the inlet (3).

At this time, the O-ring 40 coupled to the intermittent mechanism 30 on the traveling path 2a is positioned so that the supply path 2c on the diaphragm 4 side and the communication section S1 communicate with each other.

4B is a cross-sectional view illustrating a gas running state in a diaphragm breaking pressure state by remounting the gas can.

Referring to the drawings, when the gas can is remounted and gas is supplied at the diaphragm breakage pressure, the gas traveling through the traveling path 2a pressurizes the control mechanism 30 of the flow path control unit 20 to control the control mechanism 30. The movement of the intermittent mechanism 30 causes the blocking section S2 of the O-ring 40 to be positioned on the line on which the supply path 2b is formed.

By maintaining the state as described above, gas propagated to the diaphragm 4 is cut off to prevent the diaphragm 4 from being damaged. In this state, the communication section S1 is supplied to the supply path 2c and the exhaust groove 2d. It keeps you from communicating with anywhere.
