Automatic vending coffee machine

Abstract

The present invention discloses an automatic vending coffee machine, which specifically includes a piercing power component. The piercing power component drives a piercing needle to penetrate into a capsule contained in a brewing chamber, and injects hot water into the capsule through the piercing needle. After brewing, a driving member drives a rotating shaft to rotate around its own axis, and the capsule in the brewing chamber gradually tilts downward. At the same time, a guiding cylinder is sleeved on a capsule cup. When the rotating shaft rotates, it can drive a guiding shaft to move within an arc path of an arc-shaped guiding groove. The arc-shaped guiding groove guides the guiding shaft. When the capsule in the brewing chamber tilts downward, the guiding shaft drives the capsule cup to move away from the guiding cylinder, and the capsule cup also moves away from the capsule in the brewing chamber. The capsule gradually detaches from the capsule cup. When the capsule completely moves downward, the capsule can fall out of the capsule cup by its own gravity, completing capsule discharging. The capsule discharging structure of the present invention is simple and the discharging is stable.

Description

Technical Field

[0001] The present invention relates to the technical field of coffee machines, and in particular to an automatic coffee vending machine. Background Art

[0002] The current capsule coffee machine is a manual control method for adding capsules for brewing. Each time the flavor is selected and brewed manually, the taste of the original product will change. The processing of the capsule cup after brewing needs to be done manually, and the automatic vending function cannot be realized. The utility model patent with the patent publication number CN208404178U discloses a capsule coffee powder brewing vending machine. However, in the process of automatic vending, after the capsule beverage is brewed, it needs to be taken out of the capsule cup, that is, the capsule is removed. However, the existing capsule removal device uses an electromagnet, which drives the plug-in fork to plug the capsule, and then the capsule is removed from the placement. After the electromagnet is powered off, the plug-in fork of the plug-in capsule is retracted and reset by the spring force to realize the capsule removal. However, after a period of use, the spring force is insufficient, resulting in the plug-in fork being difficult to retract and reset, and the capsule still stays on the plug-in fork, resulting in a capsule removal failure. It can be seen that the existing automatic vending coffee machine still has some defects. Summary of the invention
