Description

TECHNICAL FIELD

[0001] The utility model relates to a drip coffee machine and its drip filter mechanism, and relates to a multifunctional drip coffee machine and its drip filter mechanism. BACKGROUND

[0002] A coffee machine is an electrical device for making coffee, and is generally divided into two types: semi-automatic and fully automatic. The semi-automatic coffee machine needs to be operated manually to grind, press, load, brew, and clean the coffee powder. The fully automatic coffee machine is a coffee machine that controls the whole process of brewing coffee, including preheating, cleaning, grinding, pressing, brewing, and cleaning, according to scientific data and procedures. The coffee can be brewed by simply pressing a button. However, drip coffee is a type of coffee that is made by placing a filter paper inside a funnel, putting a cup of coffee powder into the filter paper pocket, and then wetting the coffee powder with water of an appropriate temperature. After that, water is added until the coffee is ready. Some existing drip coffee machines use a drip coffee machine to make coffee. The coffee machine generally has a coffee pot, a coffee basket, and a container. For example, the Chinese patent document CN 201210026375.6, published on July 11, 2012, discloses a multi-purpose drip coffee machine. The drip coffee machine is mainly used to achieve the drip operation and the production of drip coffee through a drip valve or a drip valve. For example, the Chinese patent document CN 201710233071. X, published on July 14, 2017, discloses a drip coffee machine. Some drip coffee machines also have a coffee bean box and a grinding device. For example, the Chinese patent document CN 201520907689.6, published on May 11, 2016, discloses a full-automatic bean grinding drip coffee machine. However, the coffee basket fixing method and the flow stopping function of the above-mentioned existing drip coffee machines often have some shortcomings, such as: the traditional coffee basket fixing method is fixed inside the coffee machine, which cannot be removed and cleaned as a whole during the use of the coffee machine, and the extraction is not convenient. At the same time, the existing coffee basket cannot be placed alone on the operation table, and manual powder feeding is required during work. Some of these structures achieve automatic powder feeding by placing the coffee basket as a whole on one side of the machine. In addition, the flow stopping device of the existing drip coffee machine is not convenient to operate, or has poor sealing performance, which can easily cause coffee leakage. Not only does this waste coffee raw materials, but it also easily stains 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

[0003] To overcome the aforementioned shortcomings, the present invention aims to provide a multifunctional drip coffee maker and its drip filter mechanism to the art. These mechanisms address the technical issues of existing similar products, such as the relatively rigid coffee basket structure, inconvenient cleaning and extraction, inconvenient powder collection and dripping operations, and poorly designed positioning, limiting, sealing, and flow-stopping structures and components. This objective is achieved through the following technical solutions.
