The invention relates to the technical field of drinking water equipment, in particular to a flexible package water taking device and a water drinking device with the flexible package water taking device. The flexible package water taking device comprises a puncturing pin assembly, an elastic assembly and a protective cover assembly, the protective cover assembly includes a protective cover body and a sleeve which are movably connected, and the two ends of the elastic assembly are correspondingly connected with the protective cover body and the sleeve; the puncturing pin assembly comprises a water puncturing pin, under the gravity of flexible package water, the elastic assembly contracts, the protective cover body moves down relative to the sleeve, the water puncturing pin is exposed, andwhen the flexible package water is removed, the elastic assembly resets, and the protective cover body moves up relative to the sleeve to the top point with the top surface higher than the water puncturing pin. According to the flexible package water taking device, when the flexible package water is taken out, the water puncturing pin is completely covered by the protective cover body, autohide ofthe water puncturing pin in the process of water changing is realized, and the water puncturing pin is prevented from injuring an operator by mistake; and when the flexible package water is put on, the protective cover body moves down, the water puncturing pin is exposed, the flexible package water is punctured to achieve automatic water taking, man-made interference is avoided, the sanitary conditions of water taking are ensured, other energy drives are not needed, and energy is saved.
