Upper cover for concentrates preparation device

摘要

The invention relates to an upper cover for the concentrates preparation device. The upper cover comprises a cover body and a condensing unit, inside the upper cover is provided with a collecting portion, which includes a bar confluence rod fitting well with the interior crow surface of the cover body and a confluence ring fitting well with the interior circumferential surface of the cover body, the opening of the confluence ring is toward the top portion of the cover body, the confluence ring and the cover body define a confluence chamber, the tail end of the bar confluence rod extends to the confluence chamber which communicates with the outside through the output duct. The cooling portion of the condensing unit consists of a plurality of ring like sheets arranged coaxially and step-shaped, such arrangement enlarges the connecting area between the upper cover of the boiler and the cooling liquid so as to increase the cooling efficiency.
