Technical Field
[0001] This utility model relates to the field of grinding technology, specifically a coffee grinder. Background Technology
[0002] A coffee grinder is a tool specifically designed for grinding coffee beans. It can finely grind coffee beans into a powder suitable for different brewing methods. The coarseness of the grind directly affects the taste and flavor of the coffee. Coffee powder that is too coarse will result in a weak coffee flavor, while coffee powder that is too fine may make the coffee too bitter. Therefore, choosing the right coffee grinder and adjusting the grind size according to the brewing method is the key to making a delicious cup of coffee.
[0003] Patent CN221330996U discloses a coffee grinder, comprising a main body, a top cover screwed to the top of the main body, and a powder collection container screwed to the bottom of the main body. Both the top and bottom of the main body have screw-locking strips, and the inner side of the bottom of the top cover and the inner side of the top of the powder collection container have screw-locking grooves corresponding to the screw-locking strips. The main body, top cover, and powder collection container are all made of wood. A main shaft is installed inside the main body, with its top passing through the top cover. A handle is connected to the top of the main shaft, with a handle connector at one end and a handle head at the other end. This invention features a simple structure, screw-locking connection, quick and easy assembly and disassembly, and convenient use. The use of wood for the main body, top cover, and powder collection container results in an aesthetically pleasing appearance, good sound insulation, and reduced grinding noise transmission to the environment, providing a pleasant user experience. The top cover is not connected to the main shaft, facilitating packaging and mass production.
[0004] While the above-mentioned device solves the problem of noise from grinding metal casings easily being transmitted to the environment, it still has the following shortcomings:
[0005] The coarseness of coffee bean grind affects the taste and flavor of coffee. To change the coarseness of coffee bean grind, it is usually achieved by controlling the grinding speed or grinding time. Sometimes it may also be necessary to change the type of blade and the blade spacing. However, the blades of existing manual grinders are complicated to install and remove, and are not convenient for cleaning and maintenance. Utility Model Content
