Abstract:
1. A pepper mill comprising: a container body surrounding an axis; a driving member coupled rotatably to said container body, and cooperating with said container body to define a receiving space for receiving peppercorns; a grinding unit including a planetary gear mechanism disposed in said receiving space, and including a driving gear unit coupled co-rotatably to said driving member, and a driven gear unit coupled co-rotatably to said coupling shaft of said grinding unit and driven rotatably by said driving gear unit to drive rotation of said coupling shaft; and an adjusting unit including an adjusting component that is connected threadedly to said threaded segment of said coupling shaft, and that is operable to drive said coupling shaft and said second grinding seat to move along the axis relative to said first grinding seat so as to adjust the size of said grinding space; and wherein said planetary gear mechanism includes: said planet gears being disposed between and meshing with said ring gear and said sun gear, said coupling shaft extending rotatably through said sun gear unit and being coupled slidably and co-rotatably to said carrier, said driving member and said ring gear being rotatable relative to said container body so as to drive said planet gears to rotate respectively on said pin axles, and drive said carrier and said coupling shaft to rotate about the axis.
