[0020] In the following description, specific details of the examples are given to provide a deeper understanding of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all embodiments. It should be understood that the specific embodiments are only used to explain the present utility model and are not used to limit the present utility model.
[0021] It should be understood that when the terms "comprising" and / or "including" are used in this specification, they specify the presence of the stated features, integers, steps, operations, elements or components, but do not preclude the presence or addition of one or more other features, integers, steps, operations, elements, components or combinations thereof.
[0022] Among the coffee powders made by users themselves, the need for a coffee bean grinder is one of the conventional methods. Among them, there is a grinding disc assembly inside the coffee bean grinder. The types of grinding disc assemblies are mainly divided into flat grinding discs and conical grinding discs. Among them, the flat grinding disc can obtain a more uniform grinding particle size and is deeply liked by users. However, it is found in use that the grinding edge extension of the flat grinding disc forms a tip for grinding. However, after long-term use, the tip will become blunt, resulting in a decline in grinding performance. Therefore, a flat grinding disc assembly with a more reasonable structure is needed to solve the above-mentioned technical problems.
[0023] To solve the above-mentioned technical problems, the present application provides a grinding tooth improved grinding disc assembly. Please refer to the attached Figure 1 to the attached Figure 4 , including a flat grinding disc 1 and a grinding disc seat 2. The flat grinding disc 1 and the grinding disc seat 2 are coaxially arranged and fitted together. The grinding disc seat 2 is used to connect the flat grinding disc 1 and the output shaft of the motor. The grinding disc seat 2 is fixedly sleeved on the output shaft of the motor. When the output shaft rotates, the flat grinding disc 1 rotates with the grinding disc seat 2, and the grinding performance of coffee beans can be obtained. On the end face of the flat grinding disc 1 away from the grinding disc seat 2, there are grinding teeth 11 arranged in an annular belt. One end of the grinding teeth 11 away from the central axis of the flat grinding disc 1 forms a platform portion 12, and the length of the platform portion 12 is less than the length of the grinding teeth 11. By setting the platform portion 12, the main coffee bean grinding area is located in the inner direction of the grinding teeth 11. Since coffee beans can be ground at a more long-term and stable part of the cutting edge, the grinding particle size can be within a stable range, and the service life of the flat grinding disc 1 assembly is increased. In the specific use process, two flat grinding discs 1 are obtained, denoted as the first grinding disc and the second grinding disc. The sides with grinding teeth 11 of the two grinding discs are attached. In this state, the platform surfaces of the first grinding disc and the second grinding disc are attached to each other, and the gap between the two grinding teeth 11 forms a grinding space. The grinding disc seat 2 assembles the first grinding disc and is connected to the output shaft of the motor. The first grinding disc rotates with the rotation of the motor. At this time, the first grinding disc and the second grinding disc rotate relative to each other. The coffee beans are placed on the cutting edge of the grinding teeth 11. This cutting edge is not spiky and can slow down the blunting during use, making the service life of the grinding disc assembly longer.
[0024] In order to achieve the stable assembly of the flat grinding disc 1 and the grinding disc seat 2, in this embodiment, at least one fixing perforation 13 is provided on the end face of the flat grinding disc 1, and the grinding disc seat 2 is provided with an assembly hole 21 adapted to the fixing perforation 13. The fixing perforation 13 and the assembly hole 21 together form a space for assembling the fixing screw. Through the cooperation of the fixing perforation 13 and the assembly hole 21 with the fixing screw structure, stable assembly is achieved, and the flat grinding disc 1 can rotate stably and synchronously with the grinding disc seat 2.
[0025] In a more optimal solution, the number of the fixing perforations 13 is three, and they are arranged on the end face of the flat grinding disc 1 at equal angles. Since the flat grinding disc 1 is in a circular ring shape, through the above design, the stable assembly of the flat grinding disc 1 can be achieved without causing the locking ability to overflow and resulting in an increase in cost.
[0026] In this embodiment, an assembly sink 14 is provided on the side of the flat grinding disc 1 close to the grinding disc seat 2, and a boss 22 is provided on the grinding disc seat 2. During assembly, the boss 22 is embedded into the assembly sink 14; the assembly sink 14 and the boss 22 together form a stable fitting structure, which facilitates the rapid preliminary assembly of the flat grinding disc 1 on the grinding disc seat 2, and then it is further fixed by means of the screw structure.
[0027] In this embodiment, a plurality of groups of columns 23 are further provided on the edge of the grinding disc seat 2 close to the flat grinding disc 1, and the plurality of groups of columns 23 limit the flat grinding disc 1 on the grinding disc seat 2. After the flat grinding disc 1 is assembled on the grinding disc seat 2, it is necessary to rotate the flat grinding disc 1 to match the fixing perforation 13 and the assembly hole 21, and the columns 23 can prevent the flat grinding disc 1 from coming out during the rotation process.
[0028] In a further solution, the number of the columns 23 is three, and they are arranged on the grinding disc seat 2 at equal angles; in a further solution, the connecting line of the points formed by the columns 23 and the points formed by the fixing perforations 13 passes through the center of the flat grinding disc 1; it is not difficult to understand that during the assembly process, since the main body of the flat grinding disc 1 will block the assembly hole 21, the columns 23 play a marking role, and the user can quickly rotate the flat grinding disc 1 according to the positioning effect of the columns 23 to quickly match the fixing perforation 13 and the assembly hole 21, improving the assembly efficiency.
[0029] The advantages of the present utility model are as follows:
[0030] 1. By providing the platform part, the main coffee grinding area is located in the inner direction of the grinding teeth. Since the coffee beans can be ground in a more long-term and stable part of the cutting edge, the particle size of the grinding can be within a stable range, and the service life of the flat grinding disc assembly is increased.
[0031] 2. Through the cooperation of the fixing perforation and the assembly hole with the fixing screw structure, stable assembly is achieved, and the flat grinding disc can rotate stably and synchronously with the grinding disc seat.
[0032] The above are only several specific embodiments of the present utility model disclosed, but the present utility model is not limited thereto, and any changes that can be conceived by those skilled in the art should fall within the protection scope of the present utility model.
