Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of grinder, especially to a kind of electric grinder. BACKGROUND

[0002] Known grinder generally adopts motor drive shaft to produce torque, so that the grinding head assembly connected on the shaft rotates, and grinding operation is carried out. At present, pepper grinder belongs to kitchen supplies, which is used to grind pepper, etc. Generally, pepper powder, salt powder, etc. that have been processed can be purchased on the market, but the flavor is far from freshly ground, so people now prefer to use pepper grinder to grind themselves. The existing pepper grinder only has a single bin, and some users need to mix and grind pepper and sea salt particles by adding pepper and sea salt particles into the bin at the same time. This method needs to separate pepper and sea salt particles again when grinding pepper alone, which is very troublesome.

[0003] Therefore, a double-cavity pepper grinder with the authorization announcement number CN218219989U is disclosed in the Chinese utility model patent, which includes a shell, a motor support fixedly connected in the middle of the shell, a partition plate fixedly connected on both sides of the motor support, and the partition plate is fixedly connected with the inside of the shell at the end away from the motor support. The inside of the shell is divided into a first cavity and a second cavity by the partition plate. The main body cover is provided with two inlet channels connected with the first cavity and the second cavity respectively. The second cavity is fixedly connected with a discharge channel at the bottom, and the discharge channel is provided with a discharge port.
