Description

Technical Field

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

[0002] In recent years, coffee has gradually become an indispensable new beverage for many people every day. Coffee is a beverage made from roasted and ground coffee beans. As one of the three major beverages in the world, the coffee fruit is composed of the outer skin, pulp, inner skin, silver skin and other layers of coffee beans wrapped in the innermost layer. Before coffee becomes a beverage, an important grinding process is indispensable, and the grinding of coffee generally requires the use of a coffee grinder, which can grind coffee beans into coffee powder.

[0003] The Chinese patent with publication number CN219702163U discloses a coffee grinder, wherein a discharge port is arranged at the end of the lower screen plate, and a storage box connected to the discharge port is arranged on the side wall of the shell and located at the discharge port, and a fixed bottom plate for placing the storage box is arranged on the side wall of the draw box, and the fixed bottom plate is slidably connected to the storage box, and a connecting rod is rotatably arranged on the side wall of the shell and located above the storage box, and a rubber fixed plug for blocking the discharge port is fixedly arranged on the surface of the connecting rod to prevent dust from entering the shell when not in use.

[0004] However, the above patent has the following shortcomings: the above patent can grind coffee particles by rotating the grinding roller on the inner wall of the shell, but during use, the pulp inside the coffee contains a certain amount of water. When the grinding roller crushes the coffee particles containing relatively high water content, the water-containing coffee particles will adhere to the inner wall of the shell. At this time, the grinding roller will continue to crush the adhered coffee particles, causing them to become very hard. If they are not cleaned in time, they will deteriorate, so they need to be cleaned. Utility Model Content
