Brewing core of coffee machine

Abstract

The invention discloses a brewing core of a coffee machine. The brewing core comprises a support, a top head, a brewing device, a water inlet pipe and a ball screw rod pair; the ball screw rod pair isinstalled on the support, the brewing device is provided with a brewing cavity with an opening facing the top head, a powder falling opening is disposed nearby the opening of the brewing device, a movable filter plate is arranged in the brewing cavity, the water inlet pipe is fixed to the brewing device, and the top head is internally provided with a liquid outlet pipeline; and the brewing deviceis fixed on the support, and the top head is fixed on a sliding part of the ball screw rod pair. By adopting the brewing core of the coffee machine, the water leakage on the junction of the water inlet pipe and the brewing device can be effectively avoided.

Description

technical field [0001] The invention relates to a component of a coffee machine, in particular to a brewing core of the coffee machine. Background technique [0002] The brewing core of the coffee machine is the core component of the coffee machine for brewing coffee. The brewing core is mostly installed vertically, but for the sake of saving space, reducing the volume, and simplifying the structure of the whole machine, horizontally arranged brewing cores have also begun to appear. That is, each main component of the core is distributed laterally and moves laterally. And what this application relates to is exactly this horizontal brewing core. [0003] The brewing core of the prior art includes a head fixed to the coffee machine bracket, a power drive part installed on the head, and a brewer driven by the drive part. The power drive part is generally a horizontal ball screw pair driven by an electric motor, and the brewer It is fixed with the slider of the ball screw pair...

AI Technical Summary

Problems solved by technology

[0005] The brewing core of the coffee machine in the prior art has the following defects: firstly, a larger water inlet pressure is required for brewing, so the connection between the water inlet pipe and the brewer will bear a larger water pressure, and the brewer is movable, so Further increases the probability of water leakage at this connection; moreover, because of the hidden danger of water leakage at this location, it is necessary to equip the water inlet pipe with a solenoid valve to control its on-off, and the existence of the solenoid valve increases the cost of the brewing core and volume; again, the brewing process of the brewing core requires three actions: the screw controls the brewer t
