US 11,617,473 B2 · Grinding apparatus

Abstract

The present disclosure describes a grinding apparatus preferably comprised of upper, central and lower bodies that are magnetically connected to one another. The central body is further comprised of cutting edges positioned on a center portion to cut and evacuate herbs. The upper body is comprised of outer grinding teeth that can cut and grind herbs trapped proximate an outer rim of the central body. Inner grinding teeth positioned on the upper body and having curved inner faces abut against a correspondingly cylindrical member of the central body to limit the radial play between the upper and central bodies during operation. A teeth or gear system is also disclosed to provide torque transfer and facilitate the connection between the central and lower bodies.

Dependent claims

A grinding apparatus to grind herbs comprising:

an upper body comprising upper grinding teeth;
a central body axially aligned with and rotatably connected to the upper body, the central body further comprising:
central grinding teeth cooperating with the upper grinding teeth to grind the herbs;
at least three angular guides, each one of the at least three angular guides spaced apart from one another;
and,
at least one evacuating aperture;
and,
a lower body axially aligned with and secured to the central body, the lower body further comprised of:
a cavity to receive the herbs;
and,
a locking member to engage the at least three angular guides of the central body and provide the proper axial alignment between the lower body and the central body,
wherein the upper body is in magnetic engagement with and can be rotated independently from the central body and the central body in magnetic engagement to the lower body.
