Embodiment Construction

[0027] The following are specific embodiments of the present invention and in conjunction with the accompanying drawings, the technical solutions of the present invention are further described, but the present invention is not limited to these embodiments.

[0028] like figure 1 As shown, the casing includes a left bracket 9 and a right bracket 12, the two are fastened to form a casing with a cavity inside, the brewing chamber 2, the conversion connecting rod 10, the ejecting connecting rod 11, the upper filter plate 1, and the lower filter plate 5 are all located in the casing.

[0029] Wherein, the conversion link 10 is an approximate "凵"-shaped structure, with a hollow part in the middle, and two connecting arms protruding from both sides, and a convex cylinder is arranged on the outer surface of one end of each connecting arm connected to the middle part. The raised cylinder is connected with the concave hole provided on the inner surface of the casing bracket on the corr...

Abstract

The invention provides a coffee machine. The coffee machine comprises a machine shell, a brewing cavity and a switching connecting rod. The brewing cavity is provided with an inner cavity with an opening in the upper end, a lower filtering plate, a protruding column and an elastic piece. A water outlet is formed in the bottom of the brewing cavity. The lower filtering plate is arranged in the brewing cavity from the opening in the upper end of the inner cavity and is placed in the cross section direction of the inner cavity of the brewing cavity, so that a water outlet space is defined by the lower filtering plate and the inner cavity of the brewing cavity. Filtering holes for liquid in a brewing space to enter the water outlet space are formed in the lower filtering plate. The protruding column is arranged on the surface, facing the water outlet space, of the lower filtering plate and corresponds to the water outlet in position. The elastic piece is arranged between the lower filtering plate and the brewing cavity, and therefore the lower filtering plate can move downwards when the borne pressure is large till the protruding column is inserted into the water outlet, and the protruding column can leave the water outlet under the elastic force action of the elastic piece when the borne pressure is small. The brewing pressurization device is flexible in brewing amount, the brewing progress can be adjusted according to the brewing amount, and brewing is more sufficient.

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...
