Claims

[Scope of Claim for Utility Model Registration] (1) A ventilation hole and a steam hole are provided in the steam case installed around the discharge hole of the bellows pump, and the inside of the steam case is accessed through the ventilation hole of the inner lid installed on the inner surface of the lid body. A steam passage is formed inside the steam case leading to a steam port opening on the outer surface of the lid body, and the steam passage can be closed by pressing against the peripheral part of the ventilation hole, and when the steam passage is closed, it is possible to close the steam passage. A closure valve having a through hole communicating with the ventilation hole is accommodated, and the closure valve is biased in a direction to press against the periphery of the ventilation hole, and is separated from the periphery of the ventilation hole when the bellows pump is extended. A bellows pump device for an electric air pot, characterized in that a closing valve is suspended from an upper plate of the bellows pump by a flexible linear member so as to open a steam passage. (2) Pass through the discharge hole of the bellows pump and its inside from the vent hole of the inner lid attached to the inner surface of the lid body,
A steam passage is formed through a steam hole provided in the lower plate of the bellows pump to a steam port opening on the outer surface of the lid, and the steam passage is closed by closing the steam hole from inside the bellows pump. The bellows pump is characterized by being provided with a possible shutoff valve, and suspended by a flexible linear member on the upper plate of the bellows pump so as to open a steam passage away from the steam hole when the bellows pump is extended. Bellows pump device for electric air pot. (3) A steam passageway is formed from the vent hole in the inner lid attached to the inner surface of the lid body to the steam port opening on the outer surface, and it moves to the side of the bellows pump in a direction perpendicular to the direction of expansion and contraction of the bellows pump. possible,
Further, the steam passage is characterized by being provided with a closing valve capable of closing the steam passage, and immediately after the bellows pump is pressed down, the closing valve is driven by a cam member extending from the upper plate of the bellows pump to close the steam passage. Bellows pump device for electric air pots.
