[0016] The present application provides a coffee grinder that combines a conical grinding plate and a flat grinding plate. Referring to FIGS. 1 to 7, the grinder includes a base and a coffee bean grinding assembly. A drive motor and an assembly chamber are installed inside the base, and an opening connected to the assembly chamber is installed on the outer wall of the base. The coffee bean grinding assembly is housed within the assembly chamber. A grinding plate base is installed inside the coffee bean grinding assembly and can be detachably connected to the grinding plate base. Various types of grinding plate mechanisms can be assembled on the grinding plate base. The grinding plate mechanism rotates according to the rotation of the drive motor. Various types of grinding plate mechanisms can be assembled and used through the grinding plate base, thereby satisfying the user's requirement to grind coffee beans of various brands and types. The grinding plate base is detachable from the coffee bean grinding assembly, making cleaning and maintenance easy.

[0017] In this embodiment, the coffee bean grinding assembly (2) is composed of a detachably connected coffee bean grinding container (22) and a raw material input container (23), and the interiors of the coffee bean grinding container (22) and the raw material input container (23) jointly form a coffee bean supply passage. In a specific assembly method for the dry grinding plate mechanism and the coffee bean grinding container (22), a plurality of position limiting protrusions (221) are installed on the outer side of the grinding plate of the grinding plate mechanism, and a position limiting groove (222) that engages with the position limiting protrusions (221) is installed on the inner wall of the coffee bean grinding container (22). One end of one position limiting groove (222) extends to the side adjacent to the raw material input container (23) of the coffee bean grinding container to form an assembly portion. By engaging the plurality of position limiting protrusions (221) and the position limiting groove with each other, proper coupling between the grinding plate mechanism and the drive motor is ensured, thereby allowing for the application of a wider variety of grinding plates. The grinding plate mechanism can also be assembled in a detachable form through the position limiting projection (221) and the position limiting groove, further increasing the flexibility of disassembly and allowing the user to perform partial cleaning more easily.

[0018] In this embodiment, an assembly ring (223) is installed at one end adjacent to the raw material input container (23) of the coffee bean grinder (22), and the outer ring wall of the assembly ring (223) is a screw portion for screw connection with the raw material input container (23). A position limiting groove (222) is located on the inner wall of the assembly ring (223). A detachable assembly of the coffee bean grinder (22) and the raw material input container (23) is realized through the screw portion of the assembly ring (223), and by placing the position limiting groove (222) on the inner wall, it is advantageous to increase the tightness of the structure and reduce the product volume.

[0019] In a specific grinding plate configuration, a lower grinding plate (A2) and a grinding plate support (A1) are installed within the grinding plate base and sequentially connected coaxially. The lower grinding plate (A2), the grinding plate support (A2), and the grinding plate base are driven under the control of a drive motor to form a flat grinding plate type module (A). Alternatively, a grinding tooth (B1) is installed on the inner frame wall of the grinding plate base, and a powder remover (B3) and a conical grinding head (B2) are further included and sequentially connected coaxially within the frame formed by the grinding plate base. The powder remover (B3), the conical grinding head (B2), and the grinding plate base are driven under the control of a drive motor to form a conical grinding plate type module (B). Through the above method, the coffee bean grinding container can be assembled to accommodate different types of grinding plates, and the user can obtain ground materials of different particle sizes depending on the type of coffee beans or personal preference.

[0020] In this embodiment, the cross-sectional area of ​​the coffee bean grinder (22) is larger than the cross-sectional area of ​​the raw material input container (23), and the portion corresponding to the increased area forms a stepped structure. A locking ring is further included, which is movably placed over the raw material input container and is also detachably connected to the opening of the base. When assembled, the locking ring presses the stepped structure, causing the base, coffee bean grinder, raw material input container, and locking ring to all be in a stationary state. Since the modularly designed base (1) and coffee bean grinder assembly (2) can be quickly assembled and disassembled through the locking ring (3), in the assembled state, the locking ring (3) compresses and fixes the stepped structure (21), thereby achieving stable assembly of the base (1) and the coffee bean grinder assembly (2) and maintaining a relative stationary state, allowing the coffee bean grinding operation to be performed more smoothly. In the disassembled state, the coffee bean grinder assembly (2) and the base (1) are separated from each other, allowing the user to easily perform cleaning and maintenance.

[0021] In a more preferable configuration, a first gap (4) is formed between the opening and the coffee bean grinder (22) to expose a step structure, and the inner wall of the opening formed by the base (1) has an internal thread formed at a position corresponding to the first gap (4). A contact ring is installed on one side adjacent to the base of the locking ring, and an external thread that engages with the internal thread is installed on the outer side of the contact ring. When assembled, the contact ring pushes up the step structure.

[0022] In a specific design, a first gap (4) is formed to expose a step structure (21) between the opening and the coffee bean grinder (22), and an internal thread is formed on the inner wall of the opening formed by the base (1) at a position corresponding to the first gap (4). A contact ring (31) is installed on one side adjacent to the base (1) of the locking ring (3), and an external thread that engages with the internal thread is installed on the outer side of the contact ring (31). The user can disassemble and separate the coffee bean grinding assembly (2) and the base (1) simply by rotating the contact ring (31) during use. Specifically, for example, during the entire assembly process, the coffee bean grinding container (22) is first placed inside the assembly wall of the base (1) through the opening to complete the initial storage. Then, the locking ring (3) is placed over the exposed end of the assembly chamber of the raw material input container and slid to the first cross-section of the base (1) so that the contact ring (31) is positioned in the first gap (4). Then, the external threads and internal threads of the contact ring (31) are rotated to interlock and gradually tightened, causing the contact ring (31) to gradually fill the space formed by the first gap (4). Once fully assembled, the contact ring (31) compresses the step structure (21), so that the base (1), the locking ring (3), and the coffee bean grinding assembly (2) all remain in a stationary state, and the user can perform the grinding operation. When disassembling, the locking ring (3) is rotated in the opposite direction while the base (1) is fixed so that the contact ring (31) gradually releases contact with the step structure (21), and when the contact ring (31) is completely removed from the first gap (4), the coffee bean grinding assembly (2), the base (1), and the locking ring (3) are separated from each other, allowing the user to easily perform partial cleaning.

[0023] The advantages of this utility model are as follows.

[0024] 1) The coffee bean grinder can be assembled to use different types of grinders through the grinder base, and the user can obtain grounds of different particle sizes depending on the type of coffee beans or personal preference.

[0025] 2) Multiple groups of position limiting protrusions and position limiting grooves interlock to ensure proper coupling between the grinding plate mechanism and the drive motor, thereby allowing for the application of a wider variety of grinding plate shapes. The grinding plate mechanism can also be assembled in a detachable form through the position limiting protrusions and position limiting grooves, further increasing the flexibility of disassembly and enabling the user to perform partial cleaning more easily.
