Description

Technical Field

[0001] This utility model relates to the field of coffee grinders, and more particularly to a double-sided toothed flat grinding disc. Background Technology

[0002] With the ever-accelerating pace of life, people's demands for material goods are also increasing. Many consumers, seeking fresh, high-quality coffee, are placing higher demands on coffee grinders. A high-quality grinder requires a high-quality and efficient grinding blade assembly; therefore, such an assembly is particularly essential for coffee grinders. Currently, coffee grinders and automatic coffee grinders on the market use grinding discs to process coffee beans into coffee powder, which is then used to prepare coffee drinks, either directly or via external equipment. Coffee grinding discs are generally divided into conical and flat discs, each with its own advantages and disadvantages in grinding. Flat discs offer better uniformity and are easier to process, often making them the preferred grinding component for desktop coffee machines. However, current grinding components only have one grinding surface, which, after reaching a certain lifespan, negatively impacts the quality of the grind, ultimately affecting the quality of the coffee. Therefore, a more structurally sound solution is urgently needed to address these technical issues. Utility Model Content

[0023] To more clearly illustrate this utility model, the following description, in conjunction with the accompanying drawings, will provide a further picture.

[0024] In the following description, specific examples are given to provide a more in-depth understanding of the present invention. It is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of them. It should be understood that the specific embodiments described are only used to explain the present invention and are not intended to limit the present invention.

[0025] It should be understood that when the terms “comprising” and / or “including” are used in this specification, they indicate the presence of the said feature, integral, step, operation, element, or component, but do not exclude the presence or addition of one or more other features, integrals, steps, operations, elements, components, or combinations thereof.

[0026] To address the aforementioned technical problems, this application provides a double-sided toothed flat grinding disc, please refer to the appendix. Figure 1 To be continued Figure 7 The grinding disc includes a grinding disc body 1, with toothed surfaces 11 formed at both ends. Each 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 setting the toothed surfaces 11 on both sides of the grinding disc body 1, the grinding performance of either toothed surface 11 decreases. Users can independently remove the other side from the grinding equipment and use the other toothed surface 11 as the working surface for installation, thereby doubling the overall service life of the flat grinding disc.

[0027] 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 center line. Under this design, the thickness of the two toothed surfaces 11 is the same, 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 can be obtained after the flat grinding disc is used for a different surface.

[0028] In this embodiment, each toothed surface 11 includes a first toothed ring 111 and a second toothed ring 112 coaxially arranged. The first toothed ring 111 is located inside the second toothed ring 112, and the grinding degree of the first toothed ring 111 is less than that of the second toothed ring. Different stages of grinding are performed through the two toothed rings. Specifically, the first toothed ring 111 is used to coarsely grind the coffee beans, so that the coffee beans can be initially broken, forming a coarse powder with a larger particle size, thus achieving coarse grinding of the coffee beans. After coarse grinding, the particle size of the powder gradually decreases, which also means that the mass of the powder becomes lighter, so that powder of suitable particle size is thrown to the second toothed ring 112, where the more dense grinding teeth of the second toothed ring 112 are used for fine grinding, so as to finally achieve coffee powder with the expected particle size distribution.

[0029] In this embodiment, the mounting structure can be fixed by setting corresponding pin structures and buckles. In this embodiment, the mounting mechanism 12 is a mounting hole with two toothed surfaces 11 penetrating at both ends. The structure of the mounting hole is relatively simple, and it can be assembled onto the power source by means of an external fixing post. In a further embodiment, the middle hole wall of the mounting hole is also formed with a threaded part, and the two end faces of the mounting hole are flat ring parts. At this time, the cylindrical surface of the fixing post is provided with an external thread. The threaded part is connected and engaged with the external thread, and the flat ring part is used to form a pressure part so that the grinding disc body 1 can be tightly pressed into the expected installation position.

[0030] In this embodiment, the cutting edge of any toothed surface 11 is arranged in a clockwise direction; the other toothed surface 11 is arranged in a counterclockwise direction.

[0031] The specific settings can be as follows: the second toothed ring is formed by alternating intervals between the first fine tooth 112A and the second fine tooth 112B. The width w1 of the first fine tooth 112A is 2-3mm; the width w2 of the second fine tooth 112B is 1-2mm; the height difference ΔW between the second fine tooth 112B and the second fine tooth 112B is 0-30mm; the diameter of the grinding disc body 1 is 60-80mm. Within the above parameter design range, the grinding effect, powder yield, fineness, and consistency can be optimized. If the parameters deviate from the range, the overall grinding effect will be poor.

[0032] The advantages of this utility model are:

[0033] By placing the toothed surfaces on both sides of the grinding disc body, the grinding performance decreases on either toothed surface. Users can then easily remove the other side from the grinding equipment and use it as the working surface for installation, thereby doubling the overall service life of the flat grinding disc.

[0034] The above-disclosed embodiments are only a few specific examples of this utility model. However, this utility model is not limited thereto. Any variations that can be conceived by those skilled in the art should fall within the protection scope of this utility model.
