Abstract
Description
Technical Field
[0001] The present invention relates to the field of coffee bean grinders, in particular to a double-sided toothed flat grinding disc. Background Art
[0002] As the pace of life continues to accelerate, people's material demands are also getting higher and higher. In order to drink fresh, high-quality coffee, many users have placed higher demands on coffee bean grinders. A high-quality coffee bean grinder requires a high-quality and efficient grinding tool assembly; therefore, a grinding tool assembly is particularly necessary for coffee bean grinders. Currently, coffee bean grinders and automatic coffee bean grinders on the market all use burrs to process coffee beans into coffee powder, and then the coffee beverage is prepared by the device itself or through external equipment. Coffee burrs are generally divided into conical burrs and flat burrs, each of which has its own advantages and disadvantages in terms of grinding. Among them, flat burrs have better grinding uniformity and are easier to process, and are often the preferred grinding components for desktop coffee machines. However, current grinding components are only equipped with one grinding surface. When they reach a certain service life, the grinding quality will be affected, which will eventually affect the quality of the coffee. Therefore, a more reasonable structural solution is urgently needed to solve the above-mentioned technical problems. Summary of the Invention
[0003] The present invention provides a solution to the technical problems of the existing grinding disc assembly, which has a relatively simple structure and a short service life.

[0005] As an improved solution of the present application, the toothed surfaces at both ends are arranged in a mirror image with the central radial axis of the grinding disc body as the midline.
[0006] As an improved solution of the present application, any of the toothed surfaces includes a first tooth ring portion and a second tooth ring portion coaxially arranged, the first tooth ring portion is located on the inner ring of the second tooth ring, and the grinding degree of the first tooth ring portion is less than that of the second tooth portion.
[0007] As an improved solution of the present application, the mounting mechanism is a mounting hole, and both ends of the mounting hole pass through the two toothed surfaces.
[0008] As an improved solution of the present application, a threaded portion is further formed on the middle hole wall of the mounting hole, and both end surfaces of the mounting hole are flat ring portions.
[0009] As an improved solution of the present application, the cutting edge of any one of the tooth-shaped surfaces is arranged to rotate in a clockwise direction; and the cutting edge of the other tooth-shaped surface is arranged to rotate in a counterclockwise direction.

[0013] In order to more clearly illustrate the present invention, the present invention will be further described below with reference to the accompanying drawings.
[0014] In the following description, example details are provided to provide a deeper understanding of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, rather than all embodiments. It should be understood that the specific embodiments are only used to illustrate the present invention and are not intended to limit the present invention.
[0015] It should be understood that when the terms "comprise" and / or "include" are used in this specification, they indicate the presence of the stated features, integers, steps, operations, elements or components, but do not exclude the presence or addition of one or more other features, integers, steps, operations, elements, components or combinations thereof.
[0016] In order to solve the above technical problems, the present application provides a double-sided toothed flat grinding disc, please refer to the attached Figure 1 To the attached Figure 7 , including a grinding disc body 1, with toothed surfaces 11 formed on the front and back ends of the grinding disc body 1 respectively; any toothed surface 11 is provided with at least one mounting mechanism 12, when one toothed surface 11 is selected as the mounting surface, the other toothed surface is used as the working surface; by arranging the toothed surfaces 11 on both sides of the grinding disc body 1, when the grinding performance of any toothed surface 11 decreases, the user can independently remove the other side from the grinding equipment and install it with the other toothed surface 11 as the working surface, thereby doubling the comprehensive service life of the flat grinding disc.
[0017] In this embodiment, the toothed surfaces 11 at both ends are arranged in a mirror image with the central radial axis of the grinding disc body 1 as the midline. Under this design, the thickness of the two toothed surfaces 11 is consistent, which can ensure that the working performance of the two toothed surfaces 11 is equal, so as to ensure that the same initial grinding performance is obtained after the flat grinding disc is replaced.
[0018] In this embodiment, any toothed surface 11 includes a first tooth ring 111 portion and a second tooth ring 112 portion which are coaxially arranged. The first tooth ring 111 portion is located on the inner ring of the second tooth ring 112, and the grinding degree of the first tooth ring 111 portion is smaller than that of the second tooth portion. Different stages of grinding are performed by the two tooth ring portions. Specifically, the first tooth ring 111 portion is used to coarsely grind the coffee, so that the coffee beans can be preliminarily crushed and then form a coarse powder with a larger particle size, thereby achieving coarse grinding of the coffee beans. After coarse grinding, the particle size of the powder particles gradually becomes smaller, which also means that the weight of the powder becomes lighter, so that the powder of suitable particle size is thrown out to the second tooth ring 112 portion, and fine grinding is performed by the denser grinding teeth of the second tooth ring 112 portion, so as to finally achieve coffee powder with a desired particle size distribution.
[0019] In this embodiment, the style of the mounting structure can be relatively fixed by setting a corresponding pin structure and a snap buckle, and in this embodiment, the mounting mechanism 12 is a mounting hole, and the two ends of the mounting hole are penetrated by two toothed surfaces 11. The structure of the mounting hole is relatively simple, and it can be assembled on the power source by means of an external fixing column; in a further scheme, a threaded portion is also formed on the middle hole wall of the mounting hole, and the two end surfaces of the mounting hole are flat ring portions. At this time, the cylindrical surface of the fixing column is provided with an external thread, which is connected and matched with the external thread through the threaded portion, and then the flat ring portion is used as a pressure-bearing portion to form the grinding disc body 1 so that the grinding disc body 1 can be tightly pressed on the expected installation position.
[0020] In this embodiment, the cutting edge of any one tooth-shaped surface 11 is arranged in a clockwise rotation direction; and the cutting edge of the other tooth-shaped surface 11 is arranged in a counterclockwise rotation direction.
[0021] The specific setting parameters can be that the second ring tooth portion is formed by the first fine teeth 112A and the second selenium teeth, the width w1 of the first fine teeth 112A is 2-3mm; the width w2 of the second fine teeth 112B is 1-2mm; the height W difference between the second fine teeth 112B and the second fine teeth 112B is 0-30mm; the diameter of the grinding disc body 1 is 60-80mm; within the above parameter design range, it can ensure the optimal grinding effect, powder extraction rate, coarseness and consistency; if the parameters deviate from the range, the overall grinding effect will be poor.
[0022] The advantages of the present invention are: By setting the toothed surfaces on both sides of the grinding disc body, if the grinding performance of any toothed surface decreases, the user can independently remove the other side from the grinding equipment and install it with the other toothed surface as the working surface, thereby doubling the comprehensive service life of the flat grinding disc.
[0023] The above disclosures are only a few specific embodiments of the present invention, but the present invention is not limited thereto. Any changes that can be conceived by those skilled in the art should fall within the scope of protection of the present invention.
