Coffee making machine

Abstract

The invention relates to a coffee making machine comprising a bracket, a brewing unit, a handle assembly and a pressure buffer device. The brewing unit comprises a piston cylinder connected to the bracket, a piston arranged in the piston cylinder in an up-down sliding mode and a filtering funnel assembly. The filter funnel assembly comprises a brewing base with an inner cavity and a filter funnelconnected to the lower end of the brewing base. The piston can move downwards to be in a sealing fit relationship the brewing base to form a brewing chamber used for brewing coffee. The handle assembly is in driving connection with the pressure buffer device, and the pressure buffer device is in driving connection with the piston; the handle assembly is hinged to the piston cylinder and can rotatealong the hinge point so as to drive the pressure buffer device to slide up and down relative to the piston cylinder. The pressure buffer device of the coffee making machine has a buffering effect, aproblem that when the acting force between the piston and the filtering funnel exceeds a certain pressure value, the hand feeling is uncomfortable is solved, and the user experience is greatly improved.

Description

technical field [0001] The present invention relates to a coffee machine. Background technique [0002] At present, coffee machines generally include a bracket, a water inlet control device, a liquid outlet device, and a brewing sealed cavity for brewing coffee, wherein the brewed sealed cavity includes a brewing base that fits on the bracket in the form of a drawer, and a brewing base that is connected to the brewing base. A piston assembly with sealing fit is formed, wherein the piston assembly can be driven by the handle and the linkage transmission mechanism linked with it. Turning the handle can make the piston assembly go down, and sealingly cooperate with the brewing base to form a brewing sealed chamber for brewing coffee. [0003] In actual use, different users have different requirements for the dosage and concentration of coffee, so coffee machines are generally equipped with drawers of different specifications to brew different doses of coffee. Due to the differe...

Problems solved by technology

[0003] In actual use, different users have different requirements for the dosage and concentration of coffee, so coffee machines are generally equipped with drawers of different specifications to brew different doses of coffee. Due to the different specifications of the drawers, the distance of the piston going down will vary. It is different, wherein, in order to ensure the sealing of the coffee during the brewing process, the user must apply a large enough force to the turning handle. There are different changes, some of which have too much downforce, which brings discomfort to the user and affects the user experience
