Description

Technical Field

[0001] The utility model relates to an electrical device, and more particularly to a portable bean grinder body that can be assembled with a grinding knife set, and a magnetic powder cup and filter cup two-in-one holder is provided at the lower end through upper and lower strong magnets and a shaft hole and a rotating shaft that provide rotation or separation, and a fixing hole provided at the lower end is combined with a base with at least one cup and an embedded column at the lower end to form an integrated portable bean grinder device. Background Art

[0002] According to the common coffee bean grinders on the market, they can only be used manually. Although it takes effort to grind coffee beans, it can relieve stress and bring fun to grinding beans. However, it cannot be immediately converted to electric according to the needs of users. Therefore, when a large amount of coffee bean powder is needed to brew multiple cups of coffee at the same time, it cannot be achieved. The conventional electric coffee bean grinder is complex and bulky in structure, and the price cost is high. It needs to be plugged into the mains, and it cannot be immediately converted to manual. In addition, the conventional powder barrel structure located below the grinding tool of the conventional manual or electric coffee bean grinder is nothing more than a direct fit or The threads are screwed together, and the sleeve structure separates the two. It is unstable in use and may cause coffee bean powder to splash or overflow. The thread structure needs to be locked and loosened one by one, which is time-consuming and laborious to use. In addition, brewing coffee requires many accessories such as: grinder, filter cup, filter paper, sharing cup, bracket, etc. These accessories cannot be integrated into one and made single. Moreover, these accessories are separated one by one, and a large number of accessories need to be carried when using. Not only does the volume become larger, but it is also quite inconvenient to use, which greatly reduces its practicality. This is what the industry and consumers are eager to break through.
