Description

Technical Field

[0001] The utility model relates to the field of coffee grinding, in particular to a portable coffee grinder. Background Art

[0002] The best time to grind coffee is before brewing. Because ground coffee easily oxidizes and loses its aroma, especially if it is not properly stored, the coffee powder is easy to change its taste, and naturally it is impossible to brew a mellow coffee. Before the invention of the coffee grinder, humans used stone pestles and mortars to grind coffee beans. A doctor once experimented with this ancient tool and compared it with a modern coffee grinder. It is said that the coffee powder ground by the pestle and stone mortar can brew the most mellow flavor.

[0003] However, the coffee grinders currently in use are all large machines, which are not convenient to move and cannot be used anytime and anywhere, making them extremely inconvenient to use.

[0004] In view of this, the existing problems are studied and improved, and a portable coffee grinder is provided, which has a reasonable structural design, a compact structure, and is easy to carry and use. The design of the grinding shell, protective shell and protective cover not only ensures the stability and durability of the grinder, but also increases the safety of use. The purpose is to solve the problem and improve the practical value through this technology. Utility Model Content

[0039] Working principle and usage process:

[0040] When using the portable coffee grinder, the user first opens the grinding cover 4 and puts the coffee beans into the interior of the grinding plate 9. Then, the user can press the switch button 10 to start the grinding process. When the switch button 10 is pressed, it sends an electrical signal to the drive motor 11, so that the drive motor 11 starts working.

[0041] The driving motor 11 is connected to the carrier grinding disc 9 through the rotating wheel 13. When the driving motor 11 is started, it drives the rotating wheel 13 to rotate. The rotation of the rotating wheel 13 further drives the carrier grinding disc 9 to rotate, and the grinding blade 15 inside the carrier grinding disc 9 also rotates accordingly. The rotation of the grinding blade 15 quickly cuts the coffee beans and grinds the coffee beans into powder.

[0042] During the grinding process, the protective shell 3 and the protective cover 5 can effectively protect the internal components of the grinder, preventing the user from accidentally contacting the sharp parts such as the grinding blade 15, thereby improving the safety of use. At the same time, the outer shell 8 and the fixed outer shell 6 can also further fix and protect the internal components of the grinder.

[0043] In addition, the design of the portable coffee grinder makes it easy to carry and use. Users can use it at home, in the office or anywhere else, just press the switch button 10, and they can easily grind fresh coffee powder and enjoy delicious coffee.
