Abstract
A kettle includes a kettle body, a lid and a handle. The lid includes an inner seat having a connecting hole, an outer seat mounted on the inner seat, a sealing unit movable relative to the inner seat to open or close the connecting hole, a push rod secured to the sealing unit to move the sealing unit, and a drive shaft having a drive plate to move the push rod toward the sealing unit. The handle is connected with the drive shaft to drive and rotate the drive shaft relative to the push rod. Thus, the lid is closed at a normal state to interrupt a connection between the lid and the kettle body, so that the liquid in the kettle body will not flow outwardly from the lid even when the kettle body is inclined or upset.
