Description

Capsule conveying structure of intelligent beverage extraction machine

Technical Field

The utility model relates to a beverage vending machine especially relates to a capsule transport structure of beverage intelligence extraction drink machine.

Background

A beverage capsule based extractor, which is an extraction device for extracting the contents of a container with a corresponding juice by rapidly heating water under high pressure, is suitable for processing the container (capsule) containing the ingredients which, after interaction with a liquid introduced into the capsule, such as hot pressurized water, are capable of producing a beverage or an edible juice. The capsule is a circular truncated cone-shaped ring which can be filled with ingredients such as coffee powder, tea leaves or the like and is closed by a foil-shaped tear face cover welded or crimped to an annular rim extending radially from the side wall of the ring. A common extraction and drinking machine is a capsule coffee machine. The capsule coffee machine technology is relatively mature, but the capsule coffee machine can only be used at home, and each time coffee is prepared, the capsule is taken out from a packaging box, the coffee machine is opened by turning a handle, a coffee capsule is filled by hands, then the handle is turned to close the machine element, the machine starts to extract the beverage, and the handle is turned again after the extraction is finished, so that the capsule is removed. The existing coffee machine can not realize the automatic vending function.

Whereas existing beverage vending machines are not beverage capsule based machine devices.

Therefore, the applicant applies for an intelligent beverage extraction machine based on beverage capsules, which is a Chinese utility model with the patent number ZL201920574008.7 (publication number CN210276889U), and discloses a capsule conveying structure, wherein the beverage capsules fall out of a capsule outlet below a capsule storage rack and enter storage holes of a capsule transition storage device, the beverage capsules are locked in the storage holes by a pre-positioning structure, the beverage capsules fall out of the storage holes and are received by a capsule conveying device below the storage holes under the state that the pre-positioning structure is released from the positioning state, namely, the annular edge of the beverage capsules is placed on two slide rails of the capsule conveying device, a first belt transmission structure acts, and a pushing part moves along with a first transmission belt to push the beverage capsules to move forwards along the slide rails until the beverage capsules fall into cavities of a capsule receiving cup.

The aforesaid extract beverage machine still has the following defect:

1. the beverage capsule falling out from the lower part of the storage hole can enter the concave cavity of the capsule receiving cup only after being conveyed to the front end by the conveying structure, and the capsule receiving cup slides left and right to complete extraction, so that the structure is complex.

2. After the gear structure is removed, the lower ports of the capsule accommodating grooves are in an open state, and the weight of all the beverage capsules on each capsule accommodating groove is totally added to act on the capsules positioned in the storage holes, so that the beverage capsules cannot be firmly locked in the storage holes by the pre-positioning structure, and the situation that a plurality of beverage capsules fall at one time is easy to occur.

For this reason, the capsule storage rack structure of the aforementioned patent needs to be further improved.

SUMMERY OF THE UTILITY MODEL
