Description

Technical Field

[0001] The utility model relates to the field of coffee powder grinding devices, and particularly relates to a coffee grinder. Background Art

[0002] Coffee, a traditional Chinese medicine name, is the plant Coffea arabica L. of the genus Coffea in the family Rubiaceae. As a beverage that many people love to drink, coffee is very popular now, and there are more and more coffee shops on the roadside. However, most people currently drink instant coffee and know little about freshly ground coffee. Instant coffee can be drunk just by brewing with hot water, while ground coffee needs to grind coffee beans into powder first and then extract with tools such as an Italian coffee machine. Instant coffee will add many additives such as flavors, pigments, and preservatives. Drinking it for a long time will inevitably have an impact on human health. Freshly ground coffee is more natural and healthy. Ground coffee has a better aroma, taste, and nutrition, while instant coffee loses these during the processing.

[0003] After searching existing Chinese patents: A coffee bean grinder (publication number: CN219920901U) includes a base, a fixing groove is opened on the top surface of the base, a processing cylinder is fixedly installed inside the fixing groove, and a processing groove is opened on the top surface of the processing cylinder; a lid, the lid is movably installed on one side inside the processing groove, and a crushing shaft is arranged on the bottom surface of the lid; a noise reduction component, the noise reduction component is arranged on one side inside the processing cylinder for noise reduction. When the noise generated by crushing and grinding coffee beans, the noise is firstly absorbed and reduced by a sound absorption board. At this time, the sound wave enters the inside of a sound insulation ring, and the sound wave is reflected by a reflection block, so that the sound waves cancel each other out, improving the noise reduction effect. By arranging a sound absorption layer, sound absorption cotton is filled inside the sound absorption layer. When the sound wave is reflected by the reflection block, the sound wave enters the inside of a sound absorption hole through a through hole, further reflecting the sound wave, and then the sound wave is absorbed by the sound absorption layer, further improving the noise reduction effect.

[0004] Although the above patent firstly absorbs and reduces the noise by a sound absorption board, at this time the sound wave enters the inside of a sound insulation ring, and the sound wave is reflected by a reflection block, so that the sound waves cancel each other out, improving the noise reduction effect, when the device grinds, it cannot initially crush the coffee beans, which is not conducive to subsequent grinding. Therefore, it is very necessary to invent a coffee grinder to solve the above problems. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a coffee grinder to solve the problem that when the device grinds, it cannot initially crush the coffee beans, which is not conducive to subsequent grinding as put forward in the above background art.
