[0027] The present application provides a bean grinder that is compatible with conical grinding discs and flat grinding discs, please refer to Figures 1 to 7, which include a base body and a bean grinding assembly, wherein a driving motor and an assembly cavity are provided in the base body, and an opening communicating with the assembly cavity is provided on the outer wall of the base body; the bean grinding assembly is accommodated in the assembly cavity; a detachable grinding disc seat is provided in the grinding bean assembly, and the grinding disc seat is equipped with grinding disc mechanisms of different styles; the grinding disc mechanism rotates with the driving motor; different styles of grinding disc mechanisms can be assembled and used through the grinding disc seat to meet the user's needs for grinding different brands and categories of coffee beans; and the grinding disc seat can be detached from the grinding bean assembly for easy cleaning and maintenance. Modes for Carrying Out the Invention

[0028] In this embodiment, the bean grinding assembly 2 consists of a detachably connected bean grinding bin body 22 and a feed bin body 23, and the interior of the bean grinding bin body 22 and the feed bin body 23 together form a bean feeding channel; in the specific assembly scheme of the grinding disc mechanism and the bean grinding bin body 22, the outer side of the grinding disc of the grinding disc mechanism is provided with multiple groups of limiting protrusions 221, and the inner wall of the bean grinding bin body 22 is provided with limiting grooves 222 that are compatible with the limiting protrusions 221, and one end of any limiting groove 222 extends to the side of the bean grinding bin body close to the feed bin body 23 to form an assembly opening; through the cooperation of multiple groups of limiting protrusions 221 and limiting grooves, the rationality of the cooperation between the grinding disc mechanism and the drive motor is guaranteed, and more grinding disc styles can be expanded. The grinding disc mechanism can also be assembled in a detachable form through the limiting protrusions 221 and the limiting grooves, further expanding the flexibility of disassembly and further facilitating local cleaning by users.

[0029] In this embodiment, an assembly ring 223 is provided at one end of the bean grinding hopper body 22 close to the feed hopper body 23, and the outer ring wall of the assembly ring 223 is used for a threaded portion threadedly connected to the feed hopper body 23; the limiting groove 222 is located on the inner ring wall surface of the assembly ring 223; the threaded portion of the assembly ring 223 is used to realize the detachable installation of the bean grinding hopper body 22 and the feed hopper body 23, and placing the limiting groove 222 on the inner ring wall can increase the tightness of the structure and help reduce the volume of the product.

[0030] In the specific grinding disc style orientation, the grinding disc seat is provided with a lower grinding disc A2 and a grinding disc bracket A1 which are coaxially connected in sequence. The lower grinding disc A2, the grinding disc bracket A2 and the grinding disc seat are controlled by a drive motor to form a flat grinding disc style module A; alternatively, the inner frame wall of the grinding disc seat is provided with grinding teeth B1, and also includes a powder sweeper B3 and a conical grinding head B2 which are coaxially connected in sequence and are located in the frame formed by the grinding disc seat; the powder sweeper B3, the conical grinding head B2 and the grinding disc seat are controlled by a drive motor to form a conical grinding disc style module B; through the above scheme, the grinding bean bin can be compatible with different styles of grinding discs, and users can grind different particle sizes according to the type of coffee pod or personal preferences.

[0031] In this embodiment, the cross-sectional end surface of the bean grinding bin body 22 is larger than the area of ​​the end surface of the feed bin body 23, and the profile corresponding to the excess area forms a step structure; it also includes a locking ring, which is movably mounted on the feed bin body and is detachably connected to the open end of the base body; during assembly, the locking ring squeezes the step structure so that the base body, the bean grinding bin body, the feed bin body and the locking ring are all in a static state; the modularly designed base body 1 and the bean grinding assembly 2 are quickly assembled and disassembled by the locking ring 3. In the assembled state, the locking ring 3 is tightened to press the step structure 21, thereby achieving stable assembly of the base body 1 and the bean grinding assembly 2, keeping them relatively still for better grinding work; in the disassembled state, the bean grinding assembly 2 and the base body 1 are separated from each other, which is convenient for users to clean and maintain.

[0032] In a more preferred solution, a first gap 4 is formed between the opening and the bean grinding bin body 22 to expose the step structure, and the inner wall of the base body 1 forming the opening is provided with an internal thread at the position 3 corresponding to the first gap; an abutment ring is provided on the side of the lock ring close to the base body, and an external thread matching the internal thread is provided on the outer side of the abutment ring; during assembly, the abutment ring pushes the step structure.

[0033] In the specific solution, a first gap 4 is formed between the opening and the bean grinding bin body 22, exposing the step structure 21. The inner wall of the base body 1 forming the opening is provided with an internal thread corresponding to the first gap 4; the locking ring 3 is provided with an abutment ring 31 on the side close to the base body 1, and the outer side of the abutment ring 31 is provided with an external thread adapted to the internal thread; during use, the user only needs to rotate the abutment ring 31 to realize the disassembly and separation of the bean grinding assembly 2 and the base body 1. Specifically, during the overall assembly process, the bean grinding bin body 22 is first placed in the assembly wall of the base body 1 through the opening to complete the initial placement, and then the locking ring 3 is put on the end of the feed bin body exposed in the assembly cavity, and slides to the first end of the base body 1 When the abutting ring 31 is rotated, the outer thread and the inner thread of the abutting ring 31 are matched and gradually tightened, and the abutting ring 31 gradually fills the space formed by the first gap 4. When fully assembled, the abutting ring 31 squeezes the step structure 21, so that the base body 1, the locking ring 3 and the grinding bean assembly 2 are all in a static state, and the user can start grinding beans. When disassembling, it is only necessary to fix the base body 1 and rotate the locking ring 3 in the opposite direction to gradually release the abutment of the abutting ring 31 from the step structure 21. When the abutting ring 31 is completely out of the first gap 4, the grinding bean assembly 2, the base body 1 and the locking ring 3 can be separated from each other, which is convenient for the user to perform local cleaning. Industrial Applicability

[0034] The advantages of this utility model are:

[0035] 1) The grinding disc holder enables the grinding bean chamber to be compatible with different styles of grinding discs. Users can grind different particle sizes according to the type of coffee hopper or personal preference.

[0036] 2) Through the coordination of multiple sets of limiting protrusions and limiting grooves, the rationality of the coordination between the grinding disc mechanism and the drive motor is ensured, thereby expanding more grinding disc styles. The grinding disc mechanism can also be assembled in a detachable form through the limiting protrusions and limiting grooves, further expanding the flexibility of disassembly and further facilitating users to perform local cleaning.
