Due to the setting of the baffle 801, the liquid can be prevented from splashing, so that the liquid can flow smoothly into the separation box 5;

[0049] When the shield is set to prevent liquid splashing, the liquid can flow smoothly into the separation box 5. When the inner wall of the extraction cylinder 12 needs to be cleaned, the user can rotate the threaded rod 901, so that the threaded rod 901 drives the adjustment block 912 to move, and then drives the sealing ring 907 to move, and then drives the movable ring 906 to move, and the movable ring 906 drives the push plate 905 to rotate, and the push plate 905 drives the slide seat 902 to move, and drives the installation rod 903 to move, and then drives the cleaning brush plate 904.
