Description

Technical Field

[0001] The invention relates to a drip coffee machine and a drip filtering mechanism thereof, which are a multifunctional drip coffee machine and a drip filtering mechanism thereof. 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, loading, brewing, and manually removing residues. Fully automatic coffee machines are coffee machines that automatically control the entire process of brewing coffee, including preheating, cleaning, grinding, pressing, brewing, and draining. Coffee is brewed according to scientific data and procedures, and you can get coffee with just a light press. However, drip coffee is a type of coffee that places a piece of filter paper on the inside of the funnel, puts a cup of coffee powder into the filter paper pocket, wets the coffee powder with water of appropriate temperature, and then adds water until the coffee is ready. Some existing drip coffees are made by drip coffee machines, which are generally equipped with a coffee pot, a coffee basket, and a container, such as the application No. 201210026375.6 disclosed in the Chinese patent literature, the application publication date 2012.07.11, and the invention name "Multi-purpose drip coffee machine"; they mainly realize the drip operation and the production of drip coffee through a drip valve or a drip valve, such as the application No. 201710233071.X disclosed in the Chinese patent literature, the application publication date 2017.07.14, and the invention name "A drip coffee machine"; some of the drip coffee machines are also equipped with a coffee bean box and a grinding device, such as the application No. 201520907689.6 disclosed in the Chinese patent literature, the authorization announcement date 2016.05.11, and the utility model name "A fully automatic bean grinding drip coffee machine". However, the coffee basket fixing method and the stop function implementation of the above-mentioned existing drip coffee machines often have some shortcomings, such as: the traditional coffee basket fixing method is placed inside the coffee machine for fixing, and during the use of the coffee machine, the whole group cannot be removed for cleaning, and extraction is not convenient. At the same time, these existing coffee baskets cannot be placed on the operating table alone, and powder needs to be added to the inside of the machine filter tank manually during operation. Some of these structures realize automatic powder collection by placing the entire coffee basket on one side of the machine. In addition, the stop device of the existing drip coffee machine is usually not convenient to operate, or the sealing performance is poor, and coffee leakage is prone to occur, which not only wastes coffee raw materials, but also easily dirtys other parts of the coffee machine. Therefore, an innovative design is needed to solve these problems and improve the convenience and reliability of the drip coffee machine. Summary of the invention

[0003] In order to overcome the above shortcomings, the purpose of the present invention is to provide a multifunctional drip coffee machine and its drip filter mechanism to the art, so as to solve the technical problems of the existing similar products, such as the relatively fixed structure of the coffee basket, the inconvenience of cleaning and extraction, the inconvenience of powder receiving and dripping operations, and the poor design of the positioning, limiting, sealing, flow-stopping structure and components. The purpose is achieved through the following technical solutions.
