Flame adjusting structure of gas burner

Abstract

A flame adjusting structure is applied in a gas burner which accommodates a gas bottle and controls the gas discharge volume thereof for lighting a fire and producing a high temperature. The gas burner includes a pressing switch, a discharging component, a discharging tube, and a flame controlling gear. The flame adjusting structure includes a rotatable flame controlling component in a ring shape, which has flexibility and is sleeved around the flame controlling gear, inner teeth which are fixedly mounted on the inner edge of the rotatable flame controlling component and corresponding to and engaged with the teeth of the flame controlling gear, a sectional trench cutting off the ring of the rotatable flame controlling component, and elongation portions outwardly extended from the outer edges of the two ends of the sectional trench.

1 . A flame adjusting structure of a gas burner, wherein the gas burner accommodates a gas bottle and controls the gas discharge volume thereof for lighting a fire and producing a high temperature, and the gas burner comprises a pressing switch, a discharging component controlled by the pressing switch, a discharging tube controlled by the discharging component to discharge the gas, and a flame controlling gear located on the discharging tube for adjusting the gas discharge volume, in which the flame adjusting structure is sleeved on the flame controlling gear, the flame adjusting structure comprising:
 a rotatable flame controlling component in a ring shape, which is flexible and is sleeved around the flame controlling gear;   inner teeth, which are fixedly mounted on the inner edge of the rotatable flame controlling component and corresponding to and engaged with the teeth of the flame controlling gear;   a sectional trench, cutting off the ring of the rotatable flame controlling component; and   elongation portions, outwardly extended from the outer edges of the two ends of the sectional trench;   whereby when the two elongation portions at the two ends of the sectional trench are simultaneously forced to move toward opposite directions from the sectional trench which cuts off the rotatable flame controlling component, the inner teeth of the rotatable flame controlling component are separated from the flame controlling gear to facilitate the adjustment to the corresponding positions of the rotatable flame controlling component and the flame controlling gear, and then re-engaged with the flame controlling gear, so as to achieve a rapid assembling of the flame adjusting structure and also an easy and convenient adjustment of the gas discharge volume.   
     
     
         2 . The structure as claimed in  claim 1 , wherein the flame adjusting structure further comprises an operation sheath sleeved on the elongation portions. 
     
     
         3 . The structure as claimed in  claim 2 , wherein the operation sheath comprises a positioning point located at the inner surface thereof for engaging with an engaging point on the elongation portions. 
     
     
         4 . The structure as claimed in  claim 2 , wherein the operation sheath has a supporting block extended from the inside to the outside thereof and matched in the sectional trench, and when the operation sheath is moved toward the elongating direction of the elongation portions, the supporting block is simultaneously moved to separate the two elongation portions, thereby forcing the inner teeth of the rotatable flame controlling component to separate from the flame controlling gear. 
     
     
         5 . The structure as claimed in  claim 3 , wherein the operation sheath has a supporting block extended from the inside to the outside thereof and matched in the sectional trench, and when the operation sheath is moved toward the elongating direction of the elongation portions, the supporting block is simultaneously moved to separate the two elongation portions, thereby forcing the inner teeth of the rotatable flame controlling component to separate from the flame controlling gear. 
     
     
         6 . The structure as claimed in  claim 4 , wherein the two sides of the operation sheath used to separate the two elongation portions respectively comprise a trough formed thereon for providing the elongation portions a moving space. 
     
     
         7 . The structure as claimed in  claim 5 , wherein the two sides of the operation sheath used to separate the two elongation portions respectively comprise a trough formed thereon for providing the elongation portions a moving space.
