Abstract

The present invention relates to a grinder, comprising a container bottle for containing a spice, a grinding assembly interconnected with the container bottle and used for grinding the spice and a casing for accommodating the grinding assembly. A feeding mechanism for pushing the spice in the container bottle into the grinding assembly is further provided between the container bottle and the grinding assembly in the casing. Compared with the prior art, the design of the feeding mechanism in the present invention provides a solution for feeding of a spice with large volume and/or a relatively smooth spice with small friction in the prior art, so that the grinder provided by the present invention is applicable to not only grinding of a granular spice, but also grinding of a leafy spice with large volume and light weight.

Claims

1. A grinder, comprises a container bottle (1) for containing a spice, a grinding assembly interconnected with the container bottle (1) and used for grinding the spice and a casing (2) for accommodating the grinding assembly, wherein a feeding mechanism for pushing the spice from the container bottle (1) into the grinding assembly is further provided between the container bottle (1) and the grinding assembly in the casing (2).

2. The grinder according to claim 1, wherein the feeding mechanism is a screw rod (6) provided between the container bottle (1) and the grinding assembly and driven by external force to rotate.

3. The grinder according to claim 2, wherein a plurality of bumps (21) protruding towards the screw rod (6) are provided on the inner peripheral walls of the casing (2) facing the screw rod (6) to increase the friction between the spice and the inner wall of the casing when the screw rod feeds the spice so that feeding is more smooth.

4. The grinder according to claim 3, wherein the bumps (21) are shaped as strips and these bumps (21) are arranged in parallel to the axial axis of the screw rod (6).

5. The grinder according to claim 1, wherein the grinding assembly comprises a fixed blade (4) set in the casing (2), and a moveable blade (5), which is matched with the fixed blade (4) to cut and grind the spice and driven by external force to rotate.

6. The grinder according to claim 5, wherein the moveable blade (5) comprises a fixed base (51) driven by external force to rotate and a plurality of blades (52) connected to the periphery of the fixed base (51);

the blades (52) are arranged uniformly along the periphery of the fixed base (51).

7. The grinder according to claim 6, wherein the upper portion of the casing is provided with a hollow rotating base (3) connected to the casing (2) and capable of rotating relative to the casing (2);

the hollow rotating base (3) is provided with a rotating shaft (7) interlocked with the hollow rotating base (3);

the rotating shaft (7) drives and connects the fixed base (51) and the screw rod (6).

8. The grinder according to claim 6, wherein each blade (52) is set aslant relative to the plane where the fixed base (51) is located.

9. The grinder according to claim 7, wherein the fixed blade (4) comprises a flat plate located relative to the casing (2) and a plurality of holes (41) provided on the flat plate for the spice to pass through.

10. The grinder according to claim 9, wherein the holes (41) are provided with sharp teeth protruding inwards.
