Embodiment two, see fig. 3 and 4, differs from embodiment one in that: the second control valve 7 further comprises a second outlet end 72, the second outlet end 72 leading to said drip tray 8. When the hot water inlet end 70 is communicated with the second outlet end 72, the residual water in the second waterway 5 is discharged to the outside, so that the residual water with changed flavor is prevented from being rushed into coffee, the taste of the coffee is influenced, and the health of users is also influenced.
When the second outlet end 72 of the second control valve 7 is communicated with the first outlet end 71 during brewing of coffee, residual hot water vapor in the coffee powder cup 22 flows out of the second outlet end 72 through the first outlet end 71, and the water distribution net 23 prevents coffee powder from entering the body 21 from the water outlet 27. This prevents the user from being scalded by the hot water remaining in the coffee brewing module 2 when the coffee brewing module 2 is removed, and the coffee powder cup 22 can be removed for cleaning. Preferably, both the residual water/residual hot water vapor at the second outlet end 72 and the vapor at the vapor pressure relief end 432 are directed into the same drip tray 8.
