In this embodiment, preferably, the lower stirring structure 6 has the same structure as the upper stirring structure 10, and a discharge pipe 22 is connected to the middle position of the bottom end of the extraction box 1.

[0023] Specifically, the inner wall of the moving port 17 is connected with a sealing gasket 16.

[0024] By adopting the above technical solution, the sealing performance between the moving port 17 and the cover plate 18 is improved to prevent liquid leakage.
