grinders and grinding jars

Abstract

A grinder includes a rotating device, a rotor, and a stator. The rotating device is annular. The rotor is disposed on the rotating device and includes a base and a cone connected to the base. The cone has a plurality of angularly spaced actuating teeth in the circumferential direction and located away from the base, a plurality of angularly spaced grinding teeth in the circumferential direction and located close to the base, and a plurality of angularly spaced teeth in the circumferential direction and located between the actuating teeth and the grinding teeth in a top-to-bottom direction. The stator is annular and rotatably disposed for the rotor, and includes an inner ring tooth. The design of the angularly spaced teeth prevents larger particles from causing jamming in the grinder, thereby improving the smoothness of grinding.

Claims

1. A grinder, comprising: a rotating device in an annular shape; a rotor disposed on the rotating device and including a base, and a cone connected to the base, the cone having a plurality of angularly spaced actuating teeth in a circumferential direction and located away from the base, a plurality of angularly spaced grinding teeth in a circumferential direction and located close to the base, and a plurality of angularly spaced teeth in a circumferential direction and located between the actuating teeth and the grinding teeth in a top-to-bottom direction, the number of actuating teeth being less than the number of angularly spaced teeth, and the number of angularly spaced teeth being less than the number of grinding teeth; and a stator in an annular shape and rotatably disposed for the rotor, the stator including an inner ring tooth, wherein... The rotating device can rotate relative to the stator.

2. The grinder as claimed in claim 1, wherein, The grading teeth have a plurality of first grading teeth that continue to extend from the actuating teeth, and a plurality of second grading teeth formed between the first grading teeth.

3. The grinder as claimed in claim 2, wherein, The area of ​​each of the first grade teeth is greater than the area of ​​each of the second grade teeth.

4. The grinder as claimed in claim 1, wherein, The actuating teeth, the grading teeth, and the grinding teeth extend gradually from the bottom side to the top side along the top-bottom direction.

5. The grinder as claimed in claim 1, wherein, In a cross-section perpendicular to the top and bottom direction, each of the grinding teeth has two grinding tooth surfaces that intersect at an acute angle.

6. The grinder as claimed in claim 1, wherein, The inner ring tooth has a sparse toothed portion that is far from the seat and a dense toothed portion that is close to the seat and has more teeth than the sparse toothed portion.

7. The grinder as claimed in claim 1, wherein, The rotating device includes a rotating body and an adjusting ring operably connected to the rotating body. The rotating body has at least one positioning groove and at least one fixing groove. The width of the at least one fixing groove is not equal to the width of the at least one positioning groove. The base of the rotor has at least one positioning protrusion and at least one fixing protrusion. The at least one positioning protrusion is used to extend into the at least one positioning groove, and the at least one fixing protrusion is used to extend into the at least one fixing groove.

8. The grinder as claimed in claim 7, wherein, The rotor's base has at least one inclined guide ramp, and the rotating body also has at least one adjustment group, each adjustment group having multiple grooves. The adjustment ring has at least one adjustment post extending towards the bottom along the top-bottom direction, each adjustment post having an adjustment portion for elastically engaging with one of the grooves, and a guide portion opposite to the adjustment portion for moving along the guide ramp.

9. The grinder as claimed in claim 8, wherein, The rotating body also has an outer ring portion arranged around the perimeter and an inner ring portion spaced apart from the outer ring portion. The outer ring portion has an anti-slip structure and an indicator groove. The inner ring portion has an inner wall arranged around the perimeter and a base wall extending inward from the inner wall. The at least one positioning groove and the at least one fixing groove are located on the inner wall. The at least one adjustment group is located on the base wall. The adjustment ring also has an outer ring wall arranged around the perimeter and an inner seat body extending inward. The outer ring wall has a plurality of particle indicators for aligning the indicator groove. The at least one adjustment post is located at the bottom of the inner seat body.

10. A grinding jar comprising: a container; a base disposed on the container; and a grinder as described in any one of claims 1 to 9, the grinder being disposed on the base at the opposite end of the container.
