Gas control knob for gas stove

Abstract

A gas control knob for a gas stove includes a main body having a gas chamber connected between a gas inlet hole and a gas outlet hole, a throttling cock rotatably mounted in the main body to regulate a gas flow rate between the gas inlet hole and the gas chamber, and an electromagnetic valve mounted on the main body to control connection between the gas chamber and the gas outlet hole of the main body. Thus, the electromagnetic valve is operated to open or close the fire automatically after the rotation lever is rotated to a determined extent, thereby facilitating a user opening or closing the fire of the gas stove.

1 . A gas control knob, comprising: 
 a main body having a gas inlet hole, a gas outlet hole and a gas chamber connected between the gas inlet hole and the gas outlet hole;    a throttling cock rotatably mounted in the main body and located between the gas inlet hole and the gas chamber of the main body to regulate a gas flow rate between the gas inlet hole and the gas chamber of the main body;    an electromagnetic valve mounted on the main body and located between the gas chamber and the gas outlet hole of the main body to control connection between the gas chamber and the gas outlet hole of the main body.    
   
   
       2 . The gas control knob in accordance with  claim 1 , further comprising an end cap mounted on the main body to limit the throttling cock.  
   
   
       3 . The gas control knob in accordance with  claim 2 , further comprising a rotation lever rotatably mounted in the end cap and having a first end secured to the throttling cock to rotate the throttling cock and a second end protruding outward from the end cap.  
   
   
       4 . The gas control knob in accordance with  claim 1 , wherein the main body has a bottom formed with an outwardly extended pipe which is inserted into a gas line and has a lower end formed with a screw bore, and the gas control knob further comprises a screw member screwed into the screw bore of the pipe of the main body and rested on the gas line to secure the main body to the gas line.  
   
   
       5 . The gas control knob in accordance with  claim 4 , wherein the gas inlet hole is formed in the pipe and connected to the gas line.  
   
   
       6 . The gas control knob in accordance with  claim 1 , wherein the gas chamber is formed in a top of the main body.  
   
   
       7 . The gas control knob in accordance with  claim 1 , wherein the main body has an inside formed with a mounting hole connected between the gas inlet hole and the gas chamber.  
   
   
       8 . The gas control knob in accordance with  claim 7 , wherein the throttling cock is rotatably mounted in the mounting hole of the main body.  
   
   
       9 . The gas control knob in accordance with  claim 1 , wherein the electromagnetic valve is mounted on the top of the main body.  
   
   
       10 . The gas control knob in accordance with  claim 9 , wherein the electromagnetic valve has a top provided with an electrical connection which is electrically connected to an ignition control knob.  
   
   
       11 . The gas control knob in accordance with  claim 1 , wherein the electromagnetic valve is operated by a pressing action or by a remote control action to open or close the connection between the gas chamber and the gas outlet hole of the main body so that a gas contained in the gas chamber flows through the electromagnetic valve into the gas outlet hole of the main body.
