FIGS. 1-4 , a gas control knob for a gas stove in accordance with the preferred embodiment of the present invention comprises amain body 10 having agas inlet hole 12, agas outlet hole 13 and agas chamber 14 connected between thegas inlet hole 12 and thegas outlet hole 13, athrottling cock 16 rotatably mounted in themain body 10 and located between thegas inlet hole 12 and thegas chamber 14 of themain body 10 to regulate a gas flow rate between thegas inlet hole 12 and thegas chamber 14 of themain body 10, anelectromagnetic valve 20 mounted on themain body 10 and located between thegas chamber 14 and thegas outlet hole 13 of themain body 10 to control connection between thegas chamber 14 and thegas outlet hole 13 of themain body 10, anend cap 17 mounted on themain body 10 to limit thethrottling cock 16, and arotation lever 18 rotatably mounted in theend cap 17 and having a first end secured to the throttlingcock 16 to rotate thethrottling cock 16 and a second end protruding outward from theend cap 17. - Referring to
FIGS. 1-7 , themain body 10 has a bottom formed with an outwardly extendedpipe 11 which is inserted into agas line 1 and has a lower end formed with ascrew bore 110, and ascrew member 2 is screwed into thescrew bore 110 of thepipe 11 of themain body 10 and rested on thegas line 1 to secure themain body 10 to thegas line 1. Thegas inlet hole 12 is formed in thepipe 11 and connected to thegas line 1. Thegas chamber 14 is formed in a top of themain body 10. Themain body 10 has an inside formed with amounting hole 15 connected between thegas inlet hole 12 and thegas chamber 14. Thethrottling cock 16 is rotatably mounted in themounting hole 15 of themain body 10 and has a throttling hole that can adjust the connection area between thegas inlet hole 12 and thegas chamber 14 by rotation of thethrottling cock 16 so as to regulate the gas flow rate between thegas inlet hole 12 and thegas chamber 14 of themain body 10. Theelectromagnetic valve 20 is mounted on the top of themain body 10 and has a top provided with anelectrical connection 21 which is electrically connected to an ignition control knob (not shown) of the gas stove. - In operation, the
throttling cock 16 is rotated by therotation lever 18 to control the gas flow rate between thegas inlet hole 12 and thegas chamber 14 of themain body 10 so that the gas enters thegas chamber 14 from thegas inlet hole 12. Then, theelectromagnetic valve 20 and the ignition control knob are operated by a pressing action or by a remote control action to open the connection between thegas chamber 14 and thegas outlet hole 13 of themain body 10 so that the gas contained in thegas chamber 14 flows through theelectromagnetic valve 20 into thegas outlet hole 13 of themain body 10 and is ignited by the ignition control knob, thereby opening the fire. - On the contrary, the
electromagnetic valve 20 is operated by a pressing action or by a remote control action to interrupt the connection between thegas chamber 14 and thegas outlet hole 13 of themain body 10 so that the gas contained in thegas chamber 14 cannot flow through theelectromagnetic valve 20 into thegas outlet hole 13 of themain body 10, thereby closing the fire. - Accordingly, the
electromagnetic valve 20 is operated to open or close the fire automatically after therotation lever 18 is rotated to a determined extent, thereby facilitating a user opening or closing the fire of the gas stove. In addition, the user only needs to operate theelectromagnetic valve 20 to open or close the fire without having to rotate therotation lever 18 successively, thereby facilitating the user controlling the fire of the gas stove. - Referring to
FIGS. 8 and 9 , thepipe 11 of themain body 10 is secured to thegas line 1 in a pipe clamping manner. - Referring to
FIGS. 10 and 11 , thepipe 11 of themain body 10 is secured to thegas line 1 in a screwing manner. - Referring to
FIGS. 12 and 13 , thepipe 11 of themain body 10 is secured to thegas line 1 in a snapping manner. - Although the invention has been explained in relation to its preferred embodiment(s) as mentioned above, it is to be understood that many other possible modifications and variations can be made without departing from the scope of the present invention. It is, therefore, contemplated that the appended claim or claims will cover such modifications and variations that fall within the true scope of the invention.
