Embodiment Construction
[0024] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.
[0025] like Figure 1-7 A preferred embodiment of the invention is shown.
[0026] A brewing device for preparing leaching hot drinks, comprising a frame body 1, the frame body 1 is composed of a bottom plate 11, a top plate 12 and two uprights 13, the upper and lower ends of the two uprights 13 are stepped shafts, and the lower ends of the two uprights 13 are After the stepped shafts pass through the bottom plate 11, lock the lower part of the bottom plate 11 with nuts, and then connect the lower ends of the columns to the bottom plate 11. After the stepped shafts at the upper ends of the two columns 13 pass through the top plate 12, use nuts on the top of the top plate 12 Lock, and then the upper end of column is connected on the top plate 12.
[0027] A boiler 2 is fixed on the upper part of the frame body 1, that is, the boiler 2 is inst...

The invention relates to a brewing device for preparing leaching-type hot beverage, comprising a frame body and a boiler which comprises an upper water inlet channel and an upper water outlet channel. The invention is characterized in that the brewing device also comprises a lower fixing piece, an upper casting die, a supporting spring and a one-way valve assembly, wherein, the lower fixing pieceis fixed on the frame body, and the lower part of the lower fixing piece is provided with a lower water inlet channel; the upper casting die is arranged between the lower fixing piece and the boiler;the upper part of the upper casting die is provided with a space for containing a packaging bag and a liquid outlet channel; the lower part of the upper casting die is provided with a concave cavity with the opening facing down; the concave cavity is sheathed on the lower fixing piece, and the periphery of the lower fixing piece and the inner wall of the concave cavity are in liquid sealing matching; when the upper casting die moves upwards to the extraction position, the upper casting die and the boil can form a relatively sealed extraction space; the supporting spring is arranged between the upper casting die and the boiler; and the one-way valve assembly is arranged in the upper water outlet channel. The beverage extraction process of the brewing device needs no other auxiliary mechanical drive structure and mechanical locking mechanisms to ensure that two components are relatively closed and locked to form the extraction space, so that the structure of the brewing device is simplified, and manufacturing cost is lowered.
Description
technical field [0001] The present invention relates to a brewing device for preparing an infusion hot beverage like coffee. Background technique [0002] At present, there are many types of brewing and extraction devices for preparing infusion beverages such as coffee, and the coffee machine is the representative product. The traditional components of the coffee machine generally include a brewing head, a water tank, a heating element, and a water pump. The brewing head consists of a fixing part and a cover part that can be opened and closed relative to the fixing part. The cover part is closed relative to the fixing part under the action of the driving mechanism. The cover part and the fixing part form a closed cavity. A coffee bag containing coffee powder is placed in the closed cavity, and then the hot water boiled by the coffee machine is pumped into the chamber where the coffee bag is placed in the coffee machine, and the coffee powder in the coffee bag is drip-brewed....
