Description

Double head extraction system

technical field

The present invention relates to a beverage extraction system based on beverage capsules, in particular to a double-head extraction system, which is suitable for intelligent beverage extraction machines.

Background technique

Beverage capsule-based extraction machine is an extraction device that extracts the corresponding juice from the contents of the container by rapidly heating water at high pressure, suitable for processing containers (capsules) packed with ingredients that, after interaction with a liquid introduced into the capsule, such as hot pressurized water, can produce a beverage or edible juice. The capsule is a frustum-shaped ring filled with ingredients such as ground coffee, tea leaves or the like and closed by a foil-shaped tear-off cover welded or crimped to an annular rim extending radially from the side wall of the ring. Common extraction machines include capsule coffee machines.

Capsule coffee machine technology is relatively mature, but it can only be used for home use. Every time you prepare coffee, take the capsule out of the packaging box, turn the handle to open the coffee machine, insert a coffee capsule by hand, and then turn the handle to close the machine. The machine starts to extract the beverage. After the extraction is completed, turn the handle again to remove the capsule. Existing coffee machine can not realize vending function. There are also many types of traditional beverage vending machines, such as juice vending machines, but existing beverage vending machines are not based on beverage capsule machines.

For this reason, the applicant invented an intelligent extraction machine, such as a Chinese utility model patent "Intelligent extraction machine based on beverage capsule" with patent number ZL201920574008.7 (notification number CN210276889U) discloses such an extraction machine structure. However, the aforementioned beverage extraction machine intelligently extracts a single drink, such as coffee or tea, and now many young people like drinks with two ingredients (such as drinks such as milk coffee), and the aforementioned device cannot be realized.

Contents of the invention

The technical problem to be solved by the present invention is to provide a dual-head extraction system with reasonable structure and capable of obtaining beverages (such as milk coffee) blended with two ingredients.

The technical solution adopted by the present invention to solve the above-mentioned technical problems is: a double-head extraction system, including a capsule receiving cup, a beverage extraction group, and a tray for placing beverage cups; the feature is that: the capsule receiving cup has two left and right intervals for accommodating beverage capsules, and the bottom of each cavity is provided with beverage holes for the beverage extracted from the beverage capsule to flow out. Each machine base is provided with a brewing head, and the lower part of each machine base has a placement part with a liquid outlet hole at the bottom. When the concave cavity of the capsule receiving cup enters the corresponding placement part, the two beverage holes are connected to the two liquid outlet holes one by one;

In order to realize automatic extraction, it is further improved to include a capsule removal device for separating the extracted beverage capsules from the capsule receiving cup.

In order to manufacture an automatic beverage vending device based on beverage capsules, it is necessary to carry out a large number of modifications to the internal structure to ensure that the beverage extraction group can achieve long-distance and stable delivery of beverage capsules, which prevents the beverage capsules from being unpacked in the beverage extraction part. As an improvement, the above-mentioned capsule removal device includes a fixed frame located in the moving path of the capsule receiving cup. One side of the fixed frame is hinged with a swing frame that extends downward and can swing back and forth. The annular edge of the beverage capsule rests on the top surface of the capsule receiving cup and the peripheral edge of the capsule receiving cup is exposed. The bottom of the oscillating frame is hinged with two stripping plates arranged at intervals.

When the capsule receiving cup moves toward the beverage extraction part, the capsule receiving cup pushes the swing frame to swing toward the beverage extraction part to give way. When the capsule receiving cup moves away from the beverage extraction part, the stripping plate can extend under the annular edge of the beverage capsule that exposes the outer periphery of the capsule receiving cup to push the beverage capsule out of the corresponding cavity. The structure design of the device is reasonable, and it is suitable for unpacking the beverage capsules in the long-distance moving capsule receiving cup.

In order to facilitate the installation of the stripping plate, the bottom edge of the above-mentioned swing frame has a mounting wall extending obliquely to the left and downwards. The mounting wall has two mounting columns extending upward. The inner end of the stripping plate is movably sleeved on the mounting column.

As a further improvement, the front and rear sides of the above-mentioned installation wall have stoppers that extend obliquely to the left and downwards, and the bottom surface of the stripping plate has a stopper boss that protrudes downward, and the stopper is located in the stopper boss, and the two are matched with each other to limit the degree to which the two stripper plates are close to each other. The mutual matching between the limiting boss and the limiting part prevents the outer ends of the two stripping plates from being too close to affect the separation of the beverage capsule.

Preferably, the above-mentioned first driving structure includes a moving bracket and a first belt transmission structure, the capsule receiving cup is fixed on the moving bracket, the moving bracket is constrained on the guide rail structure extending along the left and right directions, and the moving bracket is fixed on the first transmission belt of the first belt transmission structure and slides left and right. The setting of the guide rail structure ensures that the mobile support slides smoothly, and the first belt drive structure is responsible for providing power. Of course, the first driving structure is not limited to the aforementioned structure, and an electric push rod structure may also be used.

Preferably, the above-mentioned tray is driven by a second drive structure to slide back and forth, and the second drive structure can send the tray to the bottom of the beverage extraction group. The position of the tray can be changed so that it can be moved to the cup drop position, extraction position, capping position and delivery position.

Preferably, the second drive structure includes a second belt drive structure, the tray is constrained on a slide rail structure extending in the front-to-rear direction, and the tray is fixed on the second drive belt of the second belt drive structure to slide forward and backward. The motor with the second belt transmission structure is a stepping motor, which is beneficial to control the stroke, so that the beverage cup tray can stay in a suitable position.

Compared with the prior art, the present invention has the advantages that: the capsule receiving cup has two concave cavities, that is, two beverage capsules can be placed. The capsule receiving cup is driven by the first driving structure to send the capsules to the beverage extraction group for extraction. There are two brewing positions and two brewing heads in the beverage extraction group, and the two brewing heads can work at the same time to extract the beverage capsules in the two concave cavities respectively. When it flows into the beverage cup, it can realize rapid extraction of two blended beverages (such as coffee with milk), which can be extracted at the same time or time-separated, so as to achieve different visual and sensory effects, save extraction time, and achieve a truly efficient and delicious beverage. The whole machine is upgraded from the original drinking machine. After verification, this solution can realize normal drinking.
