Fluid ice preparation device

The utility model relates to a fluid ice preparation device, which comprises a jet pump. By the aid of a fluid pump, a fluid injecting inlet of the jet pump is communicated with a water outlet of a cold water unit and/or a room-temperature water tank via a water pipe, a cold water switch valve is disposed on a water pipe at an outlet of the cold water unit, a room-temperature water switch valve is arranged on a water pipe at a water outlet of the room-temperature water tank, and a drawn fluid inlet of the jet pump is connected with an outlet of an ice maker used for preparing solid crushed ice by a feeder. Pressurized water and the solid crushed ice are mixed by the aid of the jet pump so that energy and momentum exchange between the pressured water and the solid crushed ice is realized, and the solid crushed ice is melted and sufficiently mixed with the pressured water to form fluid ice during energy and momentum exchange between the solid crushed ice and the pressured water. The fluid ice preparation device is simple in structure, can make ice without special assorted equipment, and is low in equipment cost and high in ice making efficiency.
