For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; and internal connections between two components. Those skilled in the art will understand the specific meanings of the above terms in this application based on the specific circumstances.

[0032] Refer to the following Figures 1-12 A detachable and easy-to-clean bean grinding machine core according to some embodiments of the present application is described.

[0033] A removable, easy-to-clean bean grinding mechanism includes a bean hopper 1, a bean hopper cover, a cutter block 5, a motor cover 10, and a motor block 4. An inner conical grinding disc 13 is mounted on the cutter block 5. An outer cutter assembly extends from the lower opening of the cutter block into the lower cavity of the cutter block and is secured to the cutter block by an outer cutter gasket 19. The outer conical grinding disc 14 of the outer cutter assembly forms the grinding disc with the inner conical grinding disc. Coffee beans flow down the bean discharge channel of the bean hopper and fall between the inner and outer conical grinders. The two grinders rotate relative to each other, grinding the beans into powder.

[0034] The coffee machine or grinder is topped with a top cover, which defines a first opening. The bean container is internally configured with an inverted conical slope to facilitate the passage of beans into the first opening, with its bottom engaging the first opening of the top cover. The motor cover is connected to the motor base, forming a mounting cavity for the first motor. The first motor is housed within the motor cover. The first motor's reduction sleeve is connected to an inner conical grinding shaft 12, which passes through an inner conical grinding cutter 13 and drives the inner conical grinding cutter to rotate. One end of the inner conical grinding shaft 12 extends beyond the cutter base 5, while the other end extends beyond the inner conical grinding cutter 13. Small washers and nuts 17 are used at both ends to position and secure the inner conical grinding cutter 13 to the cutter base 5.

[0035] The lower portion of the bean container is equipped with three hooks that pass through annular grooves 42 in the motor base 4 and snap onto the motor base. Below the first opening in the top cover, the machine body has a recessed cavity that accommodates the grinder. A connecting ring 3 is fixedly mounted within the recessed cavity, which serves to both accommodate and lock the grinder. Specifically, a first latching and limiting structure 30 is provided on the inner sidewall of the connecting ring 3, and a first protruding lock 40 is provided on the first outer sidewall of the motor base 4. The motor base 4 is fixedly connected to the motor cover 10 via fasteners. The motor cover 10 extends from the bean container cover. After placing the grinder into the inner cavity of the connecting ring 3 from the bottom, rotate the motor cover 10 so that the first protruding lock 40 of the motor base 4 extends into the first latching and limiting structure 30, forming a snap connection. This completes the installation of the grinder. To clean the sharpening assembly, rotate the motor cover in the opposite direction to disengage the first protruding lock 40 from the first latching and limiting structure 30, allowing the grinder to be removed from the machine body.

[0036] The connecting ring cavity houses a terminal block with terminals mounted on it. These terminals consist of springs with silver contacts at their ends. The terminal block is equipped with an L-shaped cover plate 31. A pair of electrodes 105 extend outward from the motor base. These electrodes connect to the terminals within the coffee machine body, allowing the first motor in the grinder to draw power from the machine's power supply. When the grinder is placed in the connecting ring and the motor cover is rotated to the locked position, the electrodes rotate from their initial position into the L-shaped cover plate and contact the terminals on the terminal block. Therefore, when the grinder is locked in place, the first motor is connected to a motor drive circuit powered by the machine's power supply. Pressing a switch activates the first motor, grinding the coffee beans. When the grinder leaves the locked position, the first motor loses power. This electrical connection structure allows the internal cone grinder's drive motor to be mounted vertically above the cutter, simplifying the motor drive structure, saving space, and improving efficiency.

[0037] The outer cutter assembly is relatively stationary and mounted on the cutter holder. It consists of an outer conical grinding disc 14, a grinding disc sleeve 6, and an adjustment ring 8. An adjustment gear 7 is sleeved onto the lower circumference of the adjustment ring 8 via a concave-convex fitting. The outer conical grinding disc is fixed within the inner cavity of the grinding disc sleeve 6. The top of the grinding disc sleeve 6 is provided with upwardly projecting teeth that insert into the vertical grooves of the cutter holder. The lower sidewall of the grinding disc sleeve 6 is provided with external threads that mate with the inner sidewall threads of the adjustment ring 8. When the adjustment ring rotates, the grinding disc sleeve 6 moves up and down along the vertical grooves of the cutter holder, thereby adjusting the relative gap between the outer conical grinding disc and the inner conical grinding disc. The adjustment gear 7 meshes with a driving gear 15, which is provided with a connecting shaft. One end of the connecting shaft is inserted into a first sleeve 101 protruding from the bean box. The connecting shaft or its extension shaft 16 extends from the first sleeve 101. After opening the bean box lid, the coarseness of the ground powder can be adjusted by rotating the connecting shaft or its extension shaft.

[0038] See also Figure 7-8 The motor base 4 and the knife base 5 are also connected in a detachable manner. The motor base 4 has a first cam 40 and a second locking limit structure 41. The knife base 5 is provided with a second cam 51 corresponding to the second locking limit structure 41, so that the motor base 4 and the knife base 5 form a detachable locking structure. When grinding beans is required, the motor base 4 and the knife base 5 form a snap connection relationship through the second locking limit structure 41 and the second cam 51. When it is necessary to disassemble and clean, the knife base 5 can be rotated in the opposite direction to separate the knife base and the sharpening assembly thereon from the motor base 4 to obtain an independent knife base assembly, such as Figure 9-10 The knife seat assembly can be further disassembled. After unscrewing the nut 17 and removing the gasket, the inner cone grinder 13 can be removed from the shaft 12, and the shaft 12 can also be pulled out of the knife seat. At this point, the entire movement can be disassembled and cleaned, leaving no sanitary blind spots.

[0039] Before the coffee machine starts working, first place the entire bean grinding mechanism into the inner cavity of the connecting ring 3, and rotate the motor cover to lock the mechanism and the connecting ring. At this time, a pair of electrodes on the mechanism contacts the terminals inside the machine body, the drive circuit of the first motor is connected, and the bean grinding work can begin.

[0040] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
