Puncturing piece for beverage extraction device

Abstract

The invention relates to a puncturing piece for a beverage extraction device. The puncturing piece comprises a plate body, wherein a puncturing needle protruding outwards is arranged on the front surface of the plate body; the puncturing piece is characterized in that: the puncturing needle is provided with a drainage groove sinking inwards; the front surface of the plate body is also provided with a diversion groove communicated with the drainage groove; and a liquid flowing gap is formed between the diversion groove and the back surface of the plate body. Compared with the prior art, the puncturing piece provided by the invention has the advantages that: even if the puncturing piece provided by the invention is used as a puncturing piece at a beverage outlet end, and although the packed object is closely attached around the puncturing needle due to the elastic force and the effect of high-pressure liquid flow in the packed object after the packed object is punctured by the puncturing needle, the liquid in the packed object still can smoothly flow out through the diversion groove and the liquid flowing gap communicated with the diversion groove due to the diversion groove sinking inwards on the plate body and the liquid flowing gap which is communicated with the diversion groove and can be led to the beverage outlet end. The puncturing piece provided by the invention has a simple structure and is convenient to use.

Description

technical field [0001] The invention relates to a piercing member for a beverage extracting device, which is used to pierce a jelly-like packaging box, thereby introducing hot water into the packaging box or leading brewed beverage out of the packaging box. Background technique [0002] Along with the continuous progress of society, various beverage extraction devices for brewing beverages such as coffee, fruit juice, and tea have emerged one after another. In order to adapt to modern fast-paced and simple and convenient life needs, and in order to facilitate relatively clean preparation and relatively constant control of the dose and quality of the prepared beverage, these beverage extraction devices have widely used various beverage raw materials containing predetermined packaging doses. Material packages, such as non-woven soft bags and sealed jelly-shaped packaging boxes, etc. [0003] Among them, for the beverage extraction device using a jelly-shaped packaging box, it...

Problems solved by technology

But for the piercing part at the outlet end, because the passage for the coffee to flow out has only one way out through the slot on the conical puncture needle and then flows to the inner channel of the conical puncture needle, after the conical puncture needle pierces the package, the package will be overturned The direction is opposite to the coffee discharge direction, and the high-pressure coffee in the packaging box will make the overturned packaging stick more tightly around the conical needle, which is very easy to block the slot on the conical needle, thereby affecting the coffee outflow
