Patent ID: 8168924

Claim:
An overheat protection control component for a liquid heating vessel, comprising: a control body ( 1 ); a single-integrated dual-actuation thermally sensitive bimetallic actuator ( 2 ) provided on an upper face of the control body ( 1 ), wherein the single-integrated dual-actuation thermally sensitive bimetallic actuator ( 2 ) is two integrated and relatively independent actuating units which are formed on a piece of bimetallic strip, either said actuating unit includes its own outer kick limb ( 3 ), internal tongue ( 4 ) and tongue root ( 5 ) that connects the outer kick limb ( 3 ) and the internal tongue ( 4 ), the tongue roots ( 5 ) of said two actuating units are close to each other and are integrated, the tongue tip of the internal tongue ( 4 ) and the outer kick limb ( 3 ) of said one actuating unit is remote from the same of the other actuating unit, the single-integrated dual-actuation thermally sensitive bimetallic actuator ( 2 ) is provided on the control body ( 1 ) via the internal tongues ( 4 ) thereof, and the outer kick limb ( 3 ) of either said actuating unit will produce an actuating movement downwards when an overheat state occurs; two groups of switch contacts ( 6 ) further provided on the control body ( 1 ), wherein either group of switch contacts ( 6 ) cooperate with the outer kick limb ( 3 ) of a corresponding actuating unit, and the outer kick limb ( 3 ), when producing a downward actuating movement, will open a corresponding group of switch contacts ( 6 ) and cut off the power supply of the heater for the liquid heating vessel.
