Puncturing element for water inlet end of beverage extracting device

Abstract

The invention discloses a puncturing element for a water inlet end of a beverage extracting device, which comprises a main body with an axial through hole, wherein, at least three pricking pin bases are arranged on the front end face of the main body; a pricking pin is arranged on each pricking pin base; the pricking pin is provided with at least two side faces; and all side faces are contracted to a peak A gradually upward from the bottom thereof. A temporary water entry is established between the pricking pins and a film after the pricking pins prick through a film box, and the temporary water entry can not be blocked easily. As the pricking pins can be cleaned easily, even if the pricking pins are not cleaned in time after use, the use of the pricking pins is not affected when the water entry is established next time. The puncturing element is especially suitable for the beverage extracting devices such as coffee machines, tea machines and the like.

Description

technical field [0001] The invention relates to a piercing element for the water inlet end of a beverage extracting device, which is used to pierce the packaging film on the end face of the beverage package and form a water inlet channel with the packaging film to facilitate water entering the bellows. Background technique [0002] With the continuous progress of society, people have higher and higher requirements for drinking beverages. On the other hand, in order to meet the needs of modern fast-paced and simple and convenient life, various beverage extraction devices have appeared one after another, such as coffee machines, tea machines, etc. The traditional beverage extraction device generally includes a water tank with water supply, a heating element, a brewing system, and a beverage bag feeding mechanism. The beverage bag is usually a membrane box with a thin film at one end. Since the membrane box is sealed before brewing, Before brewing, it is necessary to establish ...

AI Technical Summary

Problems solved by technology

The disadvantage of such a device is that, due to the small size of the water inlet holes on the lancets of this device, the above-mentioned water inlet holes are damaged by scale, especially if the capsule is not immediately removed from the device and the lancets are not cleaned in time after use. Or contact with the material in the membrane box, it is easy to be blocked quickly, and it is not easy to clean, which will seriously affect the normal use of the beverage extraction device

In addition, because the puncture needle is conical, and the pierced bellows film has a certain degree of toughness and elasticity, therefore, the punctured film has a tendency to retract toward the puncture needle, and is tightly wrapped around the conical puncture needle, thereby It hinders the formation of the water inlet channel and affects the smooth inflow of hot water

Furthermore, since the pricker is usually integrally arranged on a base (or main body) with a through hole inside, and the base is then mounted on the parts that accommodate the bellows through screw connections, the through hole is not easy to block, but There is still the possibility of clogging, which requires the base and needle to be removed, and existing bases are usually not easy to remove
