Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of coffee bean grinders, in particular to a self-cleaning coffee bean grinder. Background Art
[0002] After the coffee beans are ground into coffee powder, a lot of static electricity will be generated due to friction. The coffee powder carries a certain amount of charge, which will cause powder flying problems. Therefore, existing coffee grinders usually have a plasma generator at the powder outlet. The plasma generator generates positive ions with positive charge and negative ions with negative charge. The positive ions and negative ions neutralize the static coffee powder respectively, so that the coffee powder reaches an electrical balance and the coffee powder no longer flies around. However, fine coffee powder is also easily adsorbed on the emitter of the plasma generator. When the emitter of the plasma generator adsorbs too much coffee powder, the electron emission path will be blocked, making the plasma generator ineffective. The existing cleaning method usually uses a brush for cleaning, which makes the operation inconvenient. Utility Model Content
