In addition, the terms "first", "second" and the like are used for descriptive purposes only and cannot be understood as indicating or implying relative importance.

[0039] Unless otherwise defined, all technical and scientific terms used in this specification have the same meaning as those commonly understood by those skilled in the art in the field of the present invention. The terms used in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0040] Please also refer to Figure 1 、 Figure 2 and Figure 3 , Figure 1 This is a schematic structural diagram of a first coffee bean grinder provided in one embodiment of the present invention; Figure 2 This is a schematic structural diagram of a second coffee bean grinder provided in one embodiment of the present invention; Figure 3 yes Figure 1 Schematic diagram of the explosion structure of the first grinder.

[0041] An embodiment of the present invention provides a coffee bean grinder kit 100, comprising: a grinding module 10, a powder cup 20, an electric drive module 30 and a manual drive module 40. The grinding module 10 includes a grinding assembly 11 and a shell 12. The grinding assembly 11 is installed in the shell 12 and is used to grind coffee beans; the powder cup 20 is located at one end of the shell 12; the other end of the shell 12 can be selectively connected to either the electric drive module 30 or the manual drive module 40. When the electric drive module 30 is connected to the shell 12, the electric drive module 30 can drive the grinding assembly 11 to grind coffee beans. When the manual drive module 40 is connected to the shell 12, the manual drive module 40 can manually drive the grinding assembly 11 to grind coffee beans.

[0042] Specifically, the powder cup 20 can be mounted on one end of the housing 12, so that the powder cup 20, the housing 12, and the grinding assembly 11 can be used as a kit. The electric drive module 30 and the manual drive module 40 can be connected to the other end of the housing 12. In other words, the electric drive module 30 or the manual drive module 40 can be independently used as another kit. According to different needs, users can choose to connect the electric drive module 30 or the manual drive module 40 to the housing 12 to choose different ways to drive the grinding assembly 11 to grind beans to meet different user needs. The electric drive module 30 drives the grinding assembly 11 to grind through a motor. The advantage is that the speed of the grinding assembly 11 is relatively uniform during the grinding process, and the ground coffee beans are uniform. The manual drive module 40 manually drives the grinding assembly 11 to grind. The advantage is that the rotation speed is slow, almost no heat is generated during the grinding process, and the coffee flavor can be fully preserved.

[0043] See Figure 3 and Figure 4 , Figure 4 yes Figure 1 Schematic diagram of the cross-sectional structure of the electric drive module in the first coffee grinder.

[0044] In one embodiment, the electric drive module 30 includes a first housing 31 and a motor assembly 32. The motor assembly 32 is installed in the first housing 31.

The outer shell 12 is also generally cylindrical, and the second snap-fitting portion 121 is an arc-shaped protrusion. Three second snap-fitting portions 121 are also provided, and the three second snap-fitting portions 121 are circumferentially spaced apart along the central axis of the outer shell 12.

[0049] In this embodiment, the first snap portion 311 is located on the outer wall of the first shell 31, and the second snap portion 121 is located on the inner wall of the outer shell 12. When installing the electric drive module 30, one first snap portion 311 is extended into the gap between the corresponding two second snap portions 121, and the first shell 31 is continued to be pushed toward the outer shell 12 until the second snap portion 121 is located on the side of the first snap portion 311 facing the motor assembly 32. The first shell 31 is rotated so that the first snap portion 311 is abutted against the second snap portion 121. This arrangement facilitates quick disassembly and installation of the electric drive module 30.

[0050] It can be understood that in some other embodiments, the first snap portion 311 is located on the circumferential inner wall of the first shell 31, and the corresponding second snap portion 121 is located on the circumferential outer wall of the outer shell 12. When installing the electric drive module 30, one second snap portion 121 is extended into the gap between the corresponding two first snap portions 311, and the outer shell 12 is continued to be pushed toward the first shell 31 until the second snap portion 121 is located on the side of the first snap portion 311 facing the motor assembly 32, and the outer shell 12 is rotated so that the first snap portion 311 is abutted against the second snap portion 121, thereby completing the installation of the electric drive module 30.

[0051] See Figure 4 and Figure 5 , Figure 5 yes Figure 1 Schematic diagram of the cross-sectional structure of the grinding component.

The motor assembly 32 includes a second rotation limit portion 321 that can cooperate with the first rotation limit portion 1111; the outer blade disc 113 is installed on the outer shell 12, and there is a gap between the inner blade disc 112 and the outer blade disc 113.

[0053] Specifically, the first rotation limit portion 1111 and the rotating portion 1112 are an integrated structure. In this embodiment, the rotating portion 1112 is a roughly cylindrical shaft, and the first rotation limit portion 1111 is a hexagonal stud structure; the corresponding second rotation limit portion 321 is provided with a hexagonal screw hole, and the first rotation limit portion 1111 and the second rotation limit portion 321 are installed in coordination so that the motor assembly 32 or the manual drive module 40 can drive the rotating portion 1112 to rotate, and the rotating portion 1112 drives the inner cutter disc 112 to rotate, and the inner cutter disc 112 and the outer cutter disc 113 rotate relative to each other to achieve the effect of grinding the coffee beans in the gap.

[0054] Here, it should be briefly explained that the second rotation limiting portion 321 is provided on the motor shaft of the motor assembly 32 .
