Description

An Improved Coffee Pot

technical field

The utility model relates to a coffee pot, in particular to an improved coffee pot.

Background technique

At present, coffee is more and more popular among mass consumers, and drinking coffee has become a fashion in people's lives, especially for coffee lovers, a cup of fragrant and delicious coffee will greatly improve their work efficiency. In order to brew a cup of delicious coffee, it is generally necessary to grind the coffee beans before brewing. The process is generally cumbersome. In order to solve this cumbersome process, a coffee pot that integrates grinding and brewing has appeared. After the coffee beans are placed in this coffee pot, a cup of coffee can be brewed directly. For example, the Chinese patent No. 03279871.7 utility model patent discloses a coffee pot. A heating seat is extended on the lower side of a pot body for a coffee pot to be placed. The perimeter of the coffee pot. Also, a heater is arranged inside the heating seat, and a cantilever is extended on the upper side of the pot body. An opening is dug on the cantilever, and a funnel is inserted in the opening, and a grinder is arranged inside the cantilever below the opening. An outlet is provided at the front end of the cantilever, and a powder delivery pipe with an opening facing downwards is extended at the end of the cantilever, and a container is inserted above the coffee pot, a pipe body is extended below the container, and a filter is provided at the bottom of the container. In addition, several function keys are sequentially arranged on the kettle body. However, the grinder of this coffee pot cannot be disassembled. Therefore, if the grinder works for a long time, a large amount of coffee powder will stick in it, which will easily cause blockage and affect the taste of coffee.
