    • DETAILED DESCRIPTION OF THE INVENTION
  • Referring to the drawings and initially to FIGS. 1-4, a gas control knob for a gas stove in accordance with the preferred embodiment of the present invention comprises a main body 10 having a gas inlet hole 12, a gas outlet hole 13 and a gas chamber 14 connected between the gas inlet hole 12 and the gas outlet hole 13, a throttling cock 16 rotatably mounted in the main body 10 and located between the gas inlet hole 12 and the gas chamber 14 of the main body 10 to regulate a gas flow rate between the gas inlet hole 12 and the gas chamber 14 of the main body 10, an electromagnetic valve 20 mounted on the main body 10 and located between the gas chamber 14 and the gas outlet hole 13 of the main body 10 to control connection between the gas chamber 14 and the gas outlet hole 13 of the main body 10, an end cap 17 mounted on the main body 10 to limit the throttling cock 16, and a rotation lever 18 rotatably mounted in the end cap 17 and having a first end secured to the throttling cock 16 to rotate the throttling cock 16 and a second end protruding outward from the end cap 17.
  • Referring to FIGS. 1-7, the main body 10 has a bottom formed with an outwardly extended pipe 11 which is inserted into a gas line 1 and has a lower end formed with a screw bore 110, and a screw member 2 is screwed into the screw bore 110 of the pipe 11 of the main body 10 and rested on the gas line 1 to secure the main body 10 to the gas line 1. The gas inlet hole 12 is formed in the pipe 11 and connected to the gas line 1. The gas chamber 14 is formed in a top of the main body 10. The main body 10 has an inside formed with a mounting hole 15 connected between the gas inlet hole 12 and the gas chamber 14. The throttling cock 16 is rotatably mounted in the mounting hole 15 of the main body 10 and has a throttling hole that can adjust the connection area between the gas inlet hole 12 and the gas chamber 14 by rotation of the throttling cock 16 so as to regulate the gas flow rate between the gas inlet hole 12 and the gas chamber 14 of the main body 10. The electromagnetic valve 20 is mounted on the top of the main body 10 and has a top provided with an electrical 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 the rotation lever 18 to control the gas flow rate between the gas inlet hole 12 and the gas chamber 14 of the main body 10 so that the gas enters the gas chamber 14 from the gas inlet hole 12. Then, the electromagnetic valve 20 and the ignition control knob are operated by a pressing action or by a remote control action to open the connection between the gas chamber 14 and the gas outlet hole 13 of the main body 10 so that the gas contained in the gas chamber 14 flows through the electromagnetic valve 20 into the gas outlet hole 13 of the main 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 the gas chamber 14 and the gas outlet hole 13 of the main body 10 so that the gas contained in the gas chamber 14 cannot flow through the electromagnetic valve 20 into the gas outlet hole 13 of the main body 10, thereby closing the fire.
  • Accordingly, the electromagnetic valve 20 is operated to open or close the fire automatically after the rotation 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 the electromagnetic valve 20 to open or close the fire without having to rotate the rotation lever 18 successively, thereby facilitating the user controlling the fire of the gas stove.
  • Referring to FIGS. 8 and 9, the pipe 11 of the main body 10 is secured to the gas line 1 in a pipe clamping manner.
  • Referring to FIGS. 10 and 11, the pipe 11 of the main body 10 is secured to the gas line 1 in a screwing manner.
  • Referring to FIGS. 12 and 13, the pipe 11 of the main body 10 is secured to the gas 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.
