大巾に減少することとなる。Conventionally, air pots that utilize air pressure 1 have a heat source fixed to the outer periphery of an inner container surrounded by an outer case, a drain member attached to the upper end of the outer case, and an inner stopper that can be detached and attached to the center opening of the drain member. Attach the upper cover with a built-in bellows pump to the upper end of the draining member so that it can be opened and closed, and connect the air outlet of the bellows pump and the air flow path of the inner stopper through a rubber pusher fitted to the air outlet of the bellows pump. By the pressure of the bellows pump, the compressed air in the bellows pump is supplied into the inner container through the air flow path in the inner stopper, and the liquid in the inner container is transferred to the lift pipe, the liquid flow path in the inner stopper, and the discharge pipe. However, in this type of pot, steam constantly passes between the top surface of the inner stopper and the rubber pusher, so the elasticity of the rubber pusher weakens significantly during long-term use. A gap is created between the bellows and the top surface of the plug, and the compressed air inside the bellows pump escapes through this gap, resulting in a significant reduction in the discharge amount.

In an electric kettle that uses air pressure, the liquid in the inner container is supplied to the inner container via the air flow path in the inner stopper, and is discharged to the outside of the pot via the lift pipe, the liquid flow path in the inner stopper, and the discharge pipe. The upper part of the rubber pusher is shaped into a cylinder having an annular groove on the outer periphery, and the central opening of the lower plate is fitted into the annular groove, and
The inner wall of the lower part of the cylinder extends diagonally downward and inward from the outside of the lower end of the cylinder, and is shaped like a bellows extending diagonally downward and outward from the extended diagonally lower inner end. A space is provided between the lower end inner wall and the diagonally lower inner wall, between the diagonally lower inner outer wall and the diagonally lower outer outer wall, and between the top surface of the inner plug and the diagonally lower outer inner wall. , an electric kettle using pneumatic pressure, characterized in that the outer periphery of the bellows-shaped lower end is brought into contact with the upper surface of the inner stopper.
