When the pressure exceeds the atmospheric pressure, the intake valve 480 is closed and the pressure valve 460 is opened, so that the compressed air in the bellows pump BL is opened. Is supplied to the internal space Sa of the container part 310. Here, when the user releases his hand from the push plate 410, the bellows pump BL is extended by the urging force of the spring, the pressure in the bellows pump BL is lowered, and when the pressure falls below the atmospheric pressure, The pressure valve 460 is closed and the intake valve 480 is opened, and air in the atmosphere is supplied into the bellows ring pump BL. Then, the user repeats the pressing operation of the push plate 410 until a desired amount of the extracted beverage has accumulated in the container 560.

  As described above, the manual pressure unit 400 of the assembly-type pressure extractor 100 according to the present embodiment has a structure capable of locking the push plate 410 with respect to the push plate guide wall 430. Yes. For this reason, the user pushes down the push plate 410 several times, and when the user feels that the internal space Sa of the container portion 310 is sufficiently raised due to the push plate 410 being pressed, the push plate 410 is pushed down to the lower end. After that, the push plate 410 may be rotated counterclockwise to lock the push plate 410 (see FIG. 10). In this way, since the internal space Sa of the container part 310 is maintained in a pressurized state for a while, it is possible to save the user from having to press down.

<Characteristics of the assembly type pressure extractor according to the embodiment of the present invention>
(1)
The assembly type pressure extractor 100 according to the present embodiment can be divided into three members: a support member 200, a liquid storage member 300, and a manual pressure unit 400.
