External piercing extraction structure preventing liquid leakage and brewing method thereof

Abstract

The invention discloses an external piercing and extraction structure for preventing liquid leakage and a brewing method thereof. The piercing and extraction structure comprises a handle and a keeper installed below the handle. A capsule is arranged in the keeper; the keeper includes a keeper bucket and a water discharge needle installed at the bottom of the keeper bucket; the water discharge needle is located right below the aluminum foil, and a protrusion structure is arranged at any position below the top end of the water discharge needle; the protrusion structure is arranged at the outer surface of the water discharge needle in an annular shape, wherein the contacting position of the capsule and water discharge needle is made of heat-resistant elastic deformation materials; during the brewing process, through the deformation of the capsule, the capsule and the outer surface of the water discharge needle form an interference fit. According to the external piercing and extraction structure for preventing liquid leakage and the brewing method thereof, the problems that in the prior art, a keeper structure of a capsule beverage machine mostly uses the principle that stainless steel needle stab cooperates with silica gel for puncturing and sealing; the cost is higher; when the liquid is extracted, the liquid leakages easily when the liquid flows into the channel so as to cause secondary pollution are solved.

Description

technical field [0001] The invention relates to the field of capsule coffee machines, in particular to an external piercing extraction structure for preventing liquid leakage and a brewing method thereof. Background technique [0002] With the rapid development of science and technology in the world, people have a new way to deal with drinks—capsule drinks. Capsule drinks have: (1) simple and convenient operation; (2) easy to use; (3) various varieties and fresh taste, and are more and more popular among consumers. With the growing market of capsule drinks, besides the variety, environmental protection and pollution-free have also become important factors for consumers to choose. It involves (1) the flow stability of the extract of the capsule beverage machine; (2) the sealing of the flow channel of the extract of the capsule beverage machine; the design cost of the capsule beverage machine holder will be a big test. At present, most of the holder structures of capsule bev...
