Abstract

The present invention provides a coffee machine, which comprises a casing, a brewing cavity, and a conversion connecting rod; the brewing cavity has an inner cavity with an open upper end, and a water outlet hole is provided at the bottom; a lower filter plate is inserted into the brewing cavity from the upper opening and Placed along the cross-sectional direction of the brewing cavity, so as to form a water outlet space with the brewing cavity, and form a brewing space with the upper filter plate, and a hole for the liquid in the brewing space to enter the water outlet space is opened on the lower filter plate filter hole; protruding column, set on the surface of the lower filter plate facing the water outlet space, and corresponding to the position of the water outlet hole; elastic member, set between the lower filter plate and the brewing chamber, so that the lower filter plate is under high pressure It can move down until the protruding column is inserted into the water outlet hole, and the protruding column leaves the water outlet hole under the action of the elastic force of the elastic part when the pressure is applied. The brewing booster has flexible brewing volume, and can adjust the brewing process according to the brewing volume, so as to make the brewing more fully.

Description

technical field

[0001] The invention belongs to the field of coffee machines, in particular to a coffee machine adapting to different brewing volumes. Background technique

[0002] The brewing mechanism is the core working unit of an automatic coffee machine. The structures of the existing brewing mechanisms are relatively similar, generally including a main body bracket, a guiding device, a brewing head, a coffee box, and a slag ejecting device. Under the action, operations such as slag topping, slag discharge and reset are completed.

[0003] The brewing pressure of the existing brewing mechanism is generally constant. However, different brewing raw materials generally require different brewing pressures to achieve better brewing effects due to their different raw materials, different thicknesses, or different powder quantities. For example, when it is necessary to brew ESPRESSO coffee bags, ordinary American coffee bags or tea bags, because the ESPRESSO bags are thick a...
