GRINDING CORE STRUCTURE FOR BEAN GRINDER

Abstract

The present invention discloses a grinding core structure for bean grinder, which belongs to the technical field of grinding devices, comprising a frustum-shaped grinding core body. A plurality of grinding teeth are evenly distributed on the periphery of the grinding core body in the longitudinal direction. At least one first convex edge is laterally arranged at the outer side of the upper section of the grinding teeth, and at least one second convex edge is longitudinally arranged at the outer side of the lower section of the grinding teeth. The present invention provides an embodiment of a grinding core structure, in which the first convex edges of the grinding core can quickly crush beans at the beginning of grinding for subsequently grinding them into finer particles, and the second convex edges further grind crushed beans to improve grinding efficiency and uniformity of fine powder.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENT

[0020] The present invention will be further described below with reference to the drawings and embodiment. It should be appreciated that the specific embodiment described herein is merely illustrative of the present invention and is not intended to be limiting of the present invention. In addition, it should be noted that, for the convenience of description, only the parts related to the present invention are illustrated in the drawings.

[0021] It should be noted that the embodiment of the present invention and the features of the embodiment may be combined with each other under the condition of no conflict. The present invention will be described in detail below with reference to the accompanying drawings and in conjunction with the embodiment thereof.

[0022] As shown in FIGS. 1-3, this embodiment provides a grinding core structure for of bean grinder, comprising the frustum-shaped grinding core body 1. The connecting hole 3 is arranged at the central axis of the grinding core body 1. A plurality of grinding teeth 2 are evenly distributed on the periphery of the grinding core body 1 in the longitudinal direction. The grinding teeth 2 gradually widen from top to bottom and are arranged aslant relative to the axis of the grinding core body 1. At least one first convex edge 4 is laterally arranged at the outer side of the upper section of the grinding teeth 2. The first convex edge 4 is in the shape of a triangular prism, and one edge of the triangular prism faces the outside of the grinding core body 1. The first convex edges 4 are arranged parallel to the top surface of the grinding core body 1. At least one second convex edge 5 is longitudinally arranged at the outer side of the lower section of the grinding teeth 2. The second convex edge 5 is in the shape of a triangular prism, and one edge of the triangular prism faces the outside of the grinding core body 1. The second convex edges 5 are arranged along the inclined direction of the grinding teeth 2.

[0023] During the process of grinding beans, the first convex edges 4 on the grinding teeth 2 extrude beans at the beginning, which can easily and quickly crush beans in the early stage of grinding due to small force area to transform whole beans into large fragments for subsequently grinding them into finer particles. The grooves between the grinding teeth 2 extrude beans and large fragments. The inclined second convex edges 5 cut beans and large fragments until required particles and more uniform fine powder are obtained.

[0024] The technical principle used is described herein. It should be understood by those of ordinary skill in the art that the scope of the present invention is not limited to the technical schemes formed by the specific combination of the above technical features, and also covers other technical schemes formed by any combination of the above technical features or their equivalents without departing from the concept of the present invention. For example, a technical scheme is formed by substituting the above features with the technical features disclosed the present invention with (but not limited to) similar functions.
