Description

coffee grinder

technical field

The present invention relates to a bean grinding coffee machine.

Background technique

Ordinary drip coffee pots on the market adopt a conical leaking mesh structure, which is ventilated on four sides and liquid leaks from three sides. This method causes the coffee liquid to flow out too fast, the dissolution time is too short, and the coffee powder is deposited downwards, resulting in incomplete dissolution and waste. and taste issues.

Chinese Patent Document No. CN201398860Y disclosed a multifunctional coffee machine on February 10, 2010, which includes a housing and a powder box.
