Description

Technical Field

[0001] The invention relates to a thermos pot for a coffee machine, in particular to a thermos pot for a full-automatic coffee machine. Background Art

[0002] A coffee machine is an electrical device used for making coffee. It is generally divided into semi-automatic and fully automatic types. Semi-automatic coffee machines rely on manual operations for grinding, pressing, filling, brewing, and manually removing residues. Fully automatic coffee machines are coffee machines that integrate the entire process of brewing coffee, including preheating, cleaning, grinding, pressing, brewing, and draining, and are fully automatically controlled. Coffee is brewed according to scientific data and procedures, and coffee can be obtained with just a light press. Thermos pots are mainly used for keeping hot water warm. Their structure and principle are similar to those of thermos bottles and thermos cups. They generally include a pot body and a pot lid. The pot body is generally designed with a stainless steel double-layer vacuum structure. The pot body is provided with a pot wall with an insulation layer, and the pot lid is provided with a spout for discharging water. In the use of traditional coffee machines, after the coffee is finished, it often cools down quickly due to the poor insulation performance of the pot body, affecting the taste and flavor of the coffee. Among them, some coffee pots are specially used for coffee machines, or called coffee pots, which are mainly used for collecting, keeping warm and pouring coffee after it is made; such as the application number 200420150431.8 disclosed in the Chinese patent literature, the authorization announcement date 2006.02.01, and the utility model name "coffee pot"; another example is the application number 201420162091.4 disclosed in the Chinese patent literature, the authorization announcement date 2014.10.08, and the utility model name "coffee pot"; although the above coffee pots and some existing coffee pots have insulation design, they have complex structures, limited insulation time, loose functional integration, and inconvenient cleaning. For example, the sealing structure of some insulation pots is easy to fail after repeated use, resulting in accelerated heat loss; the insulation material of some pot bodies is unevenly distributed, resulting in large differences in local insulation effects; and in the process of making coffee, the contact between the coffee liquid and the pot body may affect the extraction quality of the coffee and the difficulty of cleaning the pot body.
