In this state, coffee powder and lagoon are put into the upper chamber 1 of the extraction chamber main body 1, and the mixed liquid of coffee powder and lagoon is allowed to flow down from the open communication port 15 to the lower chamber (2). Thereafter, the second cam body 10 lowers the valve body 14 to the closed position to seal the lower chamber (2), and in this sealed state pressurized air is blown from the air supply port 23 to pressurize the inside of the lower chamber (2). The mixed liquid is forcibly filtered by a filter 22 due to the pressure difference between the inside and outside of the chamber (1), and the extracted coke and liquid are collected in a filtrate receiver 13 and delivered to a cup at the product outlet.

Problems to be Solved by the Invention In such a conventional configuration, it is possible to drive the extraction chamber main body 1 up and down and the valve body 14 up and down with one gear motor 8, but the structure is complicated and the up and down movements are complicated. Since the driving position of the valve body 14 must be adjusted in relation to the extraction chamber main body 1, a large amount of time is required for adjustment, which hinders mass production.
