[0001] The invention relates to the field of coffee machines, in particular to a coffee machine with an anti-drip function. Background Art

[0002] A coffee machine is an electrical or mechanical device used to make coffee. It works by heating water to a suitable temperature and then filtering the hot water through coffee powder under a certain pressure to make coffee. There are many types of coffee machines, including traditional drip coffee machines, espresso machines, French press pots, semi-automatic and fully automatic coffee machines, etc. Each type of coffee machine has its own specific production method and working principle to meet the needs and preferences of different users, and has become an indispensable part of modern life.

[0003] After searching, it was found that the Chinese patent number CN211242888U discloses a novel drip-proof and environment-friendly coffee machine. When the coffee pot is taken away from the coffee machine, the sealing frame has no support, and the sealing plate slides down under the action of its own gravity and engages with the lower side of the brewing chamber, thereby sealing the brewing chamber to prevent coffee liquid from dripping from the coffee machine. However, when the existing coffee machine with an anti-drip function is in use, the coffee pot thereon often collides laterally with the liquid outlet during the process of taking and placing, which easily causes damage to the liquid outlet. At the same time, the liquid outlet structure of the existing equipment is simple, and dripping is likely to occur. For this reason, we propose a coffee machine with an anti-drip function.
