Description

Safety switch for gas burner Technical Field The present invention relates to a safety switch, and more particularly to a safety switch for a gas burner. The safety switch is in a locking state when not operated, and can perform pressing air supply and ignition actions when unlocked. Background Along with the transition of the times, the lighter has replaced matches as a main fire taking device, and the conventional gas burner has the advantages of strong flame, single-hand holding and operation, convenience in carrying and the like, so the lighter is popular and widely used. Because of the popularity of gas burners, children are often adept at playing with the effects of imitation and curiosity, so that they are somewhat careless to cause fires and endanger life and property. Therefore, in many cases of fire, the disaster is caused by the child play with fire, which is not counted. Because of the convenience of the common gas burner ignition switch, the operation is easy to press, so that a child can get the machine while the child is still, and unexpected results are caused. For safety reasons, various governments have made related safety regulations for gas burners, and the gas burner is required to be provided with safety switches, such as U.S. Pat. No. 6,293,782 (corresponding to taiwan patent publication No. 446104), 6,296,476 (corresponding to taiwan patent publication No. 449018), 6,527,543 (corresponding to taiwan patent publication No. 525749), 7,708,554 (corresponding to taiwan patent publication No. M306647), and 7,850,446 (corresponding to taiwan patent publication No. M338954), which are all significant examples, when the gas burner is not in use, the safety switches are in a locked state, and when the gas burner is in use, the safety switches must be released in advance before the gas burner can be pressed for gas supply and ignition. Because the release action of the safety switch increases the operation difficulty, when a child plays, the locking state cannot be released, so that the occurrence of disasters is reduced. Therefore, adding a safety switch to the gas burner to meet the relevant safety regulations of each country is a common problem for those skilled in the art. Disclosure of Invention The invention mainly aims to provide a safety switch for a gas burner, which has the functions of manual unlocking and automatic locking so as to increase the safety during operation and the durability during use. In order to achieve the above-mentioned object, the present invention provides a safety switch for a gas burner, which is configured to be mounted on a gas burner having a rear opening, wherein the rear opening is adjacent to a button, the safety switch comprises a locking member and a swing arm disposed adjacent to the locking member and pivotally connected to an inner wall of the gas burner, the locking member has a body sleeved with a longitudinal spring, the body has a push button protruding from the rear opening, and protrudes toward a hook position above the swing arm, a latch hook is disposed between an extension piece below the swing arm and the inner wall of the gas burner, when the push button is not pressed, the latch hook is in contact with the hook, and a latch bolt protruding from the bottom of the button is in contact with the latch hook, so that the button forms an unlocked state, when the push button is longitudinally pressed down to compress the longitudinal spring, and the latch hook moves down to an abutting state along the hook, so that the latch bolt loses contact with the hook, and the latch hook is released from the locked state, and the latch bolt is released from the locked state. In one embodiment, an upper end of the longitudinal spring is sleeved in a spring groove formed in the bottom of the body, and a lower end of the longitudinal spring is abutted against an abutment piece below the rear opening. In an embodiment, at least one side wall of the body is provided with a sliding rail mechanism opposite to an adjacent inner wall corresponding to the gas burner. In one embodiment, the rail mechanism includes at least one rail and at least one rail for the at least one rail to be sleeved, such that the locking member can utilize the rail mechanism to move longitudinally and elastically within the rear opening. In one embodiment, the swing arm has a shaft hole, and the shaft hole is sleeved on a shaft post protruding from the inner wall of the gas burner. In one embodiment, one end of the transverse spring is sleeved on a spring tenon of the extension piece, and the other end of the transverse spring is abutted against the inner wall of the gas burner.
