However, a gas tank for supplying gas such as gas must be installed in the gas-fired gas stove. When the gas tank is in use, it is often accompanied by an air leak or an excessive pressure to cause an unsafe condition such as a fire or an explosion. It is easy to cause a dangerous accident. The operator usually uses a gas stove in a gas stove. A safety device is installed between the burners to prevent the above accidents. In recent years, the Queen's device developed by the industry can be roughly divided into two types. One is to automatically release the gas to reduce the pressure when the gas pressure is too high, and the other is to automatically control the interrupted gas when the gas pressure is over. supply. As shown in FIG. 1, FIG. 2 and FIG. 3, a conventional gas-type gas stove j is used for seven-gas tank 10 snap-on installation, and comprises: a furnace seat 11 and a furnace head installed in the furnace seat 11. 12. A trough 13 that is closably formed on one side of the hob 11 for the valley of the trough 10, a safety device 2 mounted on the front side of the chute 3 and connected to the head 12; a latching device 14 for guiding the gas tank into the safety device 2 and a switch 15 for controlling the opening and closing of the safety device 2 and the burner 12 by pushing the gas tank toward the female full device 2 〇M342484 The safety device 2 includes a valve seat 2, the valve seat 21 has a gas chamber 2U sealed upwardly, an adjustment hole 212 communicated from the gas chamber 211 to the front side, and one position is below the gas chamber 211 The through passage 213, a through hole 214 connecting the air chamber 2U and the passage 213, and a nozzle hole 215 which is communicated to the rear side by the passage 213 and the gas tank 10 is inserted into the gas supply.

The safety control unit 24 has a passive member 241 movably extending in the actuating portion 219 from the right and the left, and a leaf spring 242 resting on the passive member 241 and being limited to the left side of the actuating portion 219. a linkage block 243 movably extending in the adapter portion 218 and abutting against the plate magazine 242, movably extending through the tapered groove portion 217 and the entry portion 216 and the peripheral edge and the tapered portion A restricting valve 244 that forms a gap between the two, a tension spring 245 fixedly mounted on the restrictor valve 244, and a fixing member 246 that connects the tension spring 245 and is sealed to the left side of the inlet portion 216. In use, the gas canister 10 is inserted into the nozzle hole 215, and the gas is poured into the inlet portion 216 of the passage 213' and the gas passes through the gap between the restrictor valve 244 and the tapered groove portion M342484 • 217, and flows in and out. The joint 218 is introduced into the gas chamber 211 by the through hole 214 and then sent to the burner 12 for ignition. In the normal air supply state, the air valve control unit 22 will close the through hole 214 in time to automatically adjust the air flow entering the air chamber 211. However, when the gas tank is abnormally fed into the gas, so that the pressure of the gas chamber 211 exceeds the set standard, the restrictor valve 244 is pushed by the gas and plugs the cone groove portion 217 to the right, so that the gas cannot enter the gas chamber 211 through the borrowing. The interrupted air supply causes the flame of the burner 丨2 to be extinguished, and the restrictor valve 244 is pushed, and the block 243 is slid, and the plate spring 242 is deformed to interlock the passive member 241 to protrude from the passage 213. When the user wants to recover the abnormal condition and wants to resume the air supply, the reset pusher 25 must be pushed to push the passive member 241 into the passage 213, so that the above-mentioned related members are respectively reset. However, since a plurality of meandering passages must be formed in the valve seat 21, in particular, the nozzle holes 215 and the passage 213 are in a turning direction and are not located on the same axis, which is cumbersome to manufacture. In addition, the number of components of the safety control unit 24 installed in the passage 213 is large, and (4) the small components of the ground are also #, must be refined, in order to operate accurately, and if the components are not precisely manufactured, the f is easy to act due to inaccuracy. Accidents occur, so it is not easy to manufacture and assemble. Furthermore, 'the safety control unit 24 must be controlled to make the plate 242 play in different directions. However, if the plate spring is not manufactured accurately, or the error occurs when the plate spring 242 is installed, then When the operation is likely to cause the leaf spring 242 to be stuck and cannot be bent with the preset position, it is often caused by a mistake. In addition, when the passive member 241 protrudes out of the passage 213, there is no other latching mechanism inside and outside. Therefore, if the high pressure has not been released, the passive member 241 may be caused by accidentally touching the 7 M342484. An accident occurs when pushed into the channel 213.

At this time, the shaft Η does not protrude from the through hole 424, and the latching plate 71 is partially covered in front of the through hole 424. As shown in FIG. 4 and FIG. 6, the nozzle of the gas canister 3 is inserted into the sound hole 43' by using the sunburst, and the plunger 6 is pushed forward to the aeration position to make the first gas seal ring 62. Leaving the first-cone groove portion 425 and leaving the second gas seal ring 63 away from the through hole 44', the head 611 of the shaft 61 protrudes from the through hole 424, and the push-up causes the click plate 71 to be centered on the pivot 72 Moving sideways, the torsion spring 73 accumulates a reset torque. At this time, the gas of the gas canister 3 enters the through hole 44 through the peripheral gap of the first gas seal ring 62 as shown by the arrow in the figure, and then passes through the gas valve control unit 5 The control enters the air chamber 41 one after another. Fig. 6 shows the valve head 51 closing the through hole 44. The gas in the air chamber 41 is further sent to a burner (not shown) for ignition. Further, in the normal air supply state, the air valve control unit 5 will close the through hole 44 in time to automatically adjust the air flow into the air chamber 41, that is, when the gas enters through the through hole 44, filling the air chamber 41 and topping When the piston soft plate 52 is pushed, the connecting member 53 will move upwards and drive the valve stem 51 to close the through hole 12 M342484, and at the same time, the pressing spring 54 will be compressed, and when the gas is output, the pressure is reduced, so that the pressure can be reduced. The return spring of the pressing spring 54 pushes the connecting member, the active soft plate 52 and the intermediate rod 51 to be reset, and the through hole 44 (see Fig. 5) is opened to allow the gas to enter the replenishment. T Fig. 7 and Fig. 8 'When the gas tank 3 If the pressure of the injected gas is too high, the body will push the shaft 61 to move forward to the gas seal position. At this time, a gas seal ring 62 will be plugged against the second tapered groove portion, so that the gas cannot pass through the through hole material. When the air chamber 4 is interrupted, the air supply is interrupted, and the compression spring 64 is also compressed to accumulate a reset elastic force. The card slot 612 of the shaft 61 corresponds to the card board 71, so By the torsion force of the 73 (see Figure 4) of the reset torque, the card plate 71 is swung in the card slot 612 to make the shaft 61 positioning. When the user wants to restore the air supply, the card engine board 7 must be pressed as shown by the arrow in Fig. 8 to let the card board 71 imaginary line as shown in the figure: The shaft 61 is reset by the return spring force of the compression spring 64. It can be seen from the above description that the nozzle hole 43 of the present invention is formed on the same axis as the passage 42. Therefore, the passage design in the valve seat 4 can be simplified, and the manufacturing is relatively simple. Moreover, the number of components of the safety control unit 6 of the present invention is less than conventional, so that it is not only easy to assemble, but also the precision of the components can be reduced in manufacturing. It is easy to manufacture. = make, so that the action is true without accidents. Moreover, the present invention locates the shaft 61 through the card f positioning unit 7 on the sniper to avoid accidental or other factors in the case where the height has not been lifted. As a result of the accident caused by the drought and the 13 M342484, the safety can be further enhanced, so the new model can achieve the purpose of the present invention. Therefore, the present invention is not only an unprecedented innovation, It can be used in the industry. It is only the preferred embodiment of the present invention, and the scope of the present invention cannot be limited by this, that is, the simplicity of the patent application scope and the new description content of the present invention. Equivalent changes and modifications are still within the scope of this new patent.
