Abstract: An electric grinder is provided that includes a shell. The shell accommodates a grinding mechanism, a reducing mechanism and a power mechanism. The electric grinder also comprises a grinding chamber, where said grinding mechanism is at one end of said grinding chamber, said power mechanism and said reducing mechanism are at the other end of said grinding chamber. The grinding chamber is provided with a filling hole, and a chamber cover is provided opposite to said filling hole. The filling hole of said grinding chamber can be opened or closed by turning said chamber cover. The electric grinder is designed so that the filling hole of the grinding chamber can be easily opened or closed by turning the chamber cover. After the chamber cover rotates and closes the filling hole, the grinding chamber is sealed and no material will flow out easily, and the chamber cover will not fall off.

Abstract: The present patent discloses an electric grinder, comprising a shell, a motor assembly, a grinding assembly and a dust cover. The motor assembly and grinding assembly are provided in the shell, and an opening is provided at one end of said shell. The dust cover comprises a cover and a counterweight part, and can open or close the opening of the shell under the gravity of the counterweight part. In the electric grinder provided by the present invention, when the opening of the grinder faces downward, the dust cover can open automatically. When the opening of the grinder faces upward, rotating the dust cover can close and engage with the opening of the dust cover automatically. Thus, the present invention prevents the feed opening of the electric grinder from being exposed to air when the user forgets to close the dust cover.
