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

[0033] A detachable and easy-to-clean bean grinding machine core comprises a bean box 1, a bean box cover, a knife seat 5, a motor cover 10, and a motor seat 4. An inner cone grinder 13 is mounted on the knife seat 5. An outer knife assembly extends from the lower opening of the knife seat into the lower cavity of the knife seat, and the outer knife assembly is fixedly mounted on the knife seat by an outer knife gasket 19. The outer cone grinding disc 14 of the outer knife assembly and the inner cone grinder form a grinding knife element. Coffee beans go down from the bean lowering channel of the bean box and fall between the inner and outer cone grinders. The two grinders rotate relative to each other to grind the beans into powder.

[0034] A top cover is arranged on the top of the body of the coffee machine or grinder, and a first opening is formed on the top cover. An inverted conical slope is arranged inside the bean box to facilitate beans to fall into the first opening, and the bottom thereof matches the first opening of the top cover. The motor cover is connected to the motor seat to form a mounting cavity for the first motor. The first motor is inside the motor cover. The first motor reduction sleeve is connected to the inner cone grinding shaft 12. The inner cone grinding shaft 12 passes through the inner cone grinding cutter 13 and drives the inner cone grinding cutter to rotate. One end of the inner cone grinding shaft 12 extends out of the cutter seat 5, and the other end extends out of the inner cone grinding cutter 13. The two ends are positioned and installed by small gaskets and nuts 17 to fix the inner cone grinding cutter 13 on the cutter seat 5.

[0035] Three hooks are arranged at the lower part of the bean box, and the hooks pass through the annular groove 42 of the motor seat 4 and are buckled on the motor seat. The body is provided with a sink cavity that can accommodate the bean grinder movement below the first opening of the top cover, and a connecting ring 3 is fixedly arranged in the sink cavity. The connecting ring 3 has the function of accommodating the bean grinder movement and locking the movement. Specifically, a first locking limit structure 30 is arranged on the inner cavity side wall of the connecting ring 3, and a first convex lock 40 is arranged on the first outer side wall of the motor seat 4. The motor seat 4 is fixedly connected with the motor cover 10 by fasteners, and the motor cover 10 extends out of the bean box cover. After the bean grinder movement is placed into the inner cavity of the connecting ring 3 from the bottom, the motor cover 10 is rotated so that the first convex lock 40 of the motor seat 4 extends into the first locking limit structure 30 and forms a buckle connection, and the movement installation is completed at this time. When it is necessary to clean the knife sharpening assembly, the motor cover is rotated in the opposite direction so that the first convex lock 40 is disengaged from the first locking limit structure 30, and the bean grinder movement can be taken out of the body at this time.

[0036] The inner cavity of the connection ring is provided with a terminal seat, and a wiring terminal is installed on the terminal seat. The wiring terminal includes a spring sheet and a silver contact on the end of the spring sheet. The terminal seat is provided with an L-shaped cover plate 31, and a pair of electrodes 105 extend outward from the motor seat. The function of the electrodes is to conduct and connect with the wiring terminals in the coffee machine body, so that the first motor in the bean grinder can be powered by the power supply of the coffee machine. When the bean grinder is placed in the connection ring and the motor cover is rotated to the locking position, the electrode is screwed into the L-shaped cover plate from the initial position and contacts with the wiring terminal of the terminal seat. Therefore, when the bean grinder is locked on the body, the first motor is connected to the motor drive circuit powered by the power circuit of the coffee machine. At this time, pressing the switch can make the first motor work and grind the coffee beans. When the bean grinder leaves the locking position of the body, the first motor loses power. This electrical connection structure enables the drive motor of the inner cone grinder to be arranged on the cutter in a vertical installation manner, and the drive structure of the motor can be simplified, saving space and improving efficiency.

[0037] The outer knife assembly is relatively statically mounted on the knife seat. The outer knife assembly is composed of an outer cone grinding disc 14, a grinding disc sleeve 6, and an adjusting ring 8. The adjusting gear 7 is sleeved on the lower circumference of the adjusting ring 8 through a concave-convex matching structure. The outer cone grinding disc is fixed in the inner cavity of the grinding disc sleeve 6. The top of the grinding disc sleeve 6 is provided with a convex tooth extending upward, which is inserted into the vertical groove of the knife seat. The lower side wall of the grinding disc sleeve 6 is provided with an external thread. The external thread of the grinding disc sleeve 6 matches the inner side wall thread of the adjusting ring 8, so that when the adjusting ring rotates, the grinding disc sleeve 6 moves up and down along the vertical groove of the knife seat, thereby adjusting the relative gap size between the outer cone grinding disc and the inner cone grinding disc. The adjusting gear 7 is meshed with the driving gear 15. The driving gear is provided with a connecting shaft. One end of the connecting shaft is inserted into the first barrel sleeve 101 protruding in the bean box. The connecting shaft or the extension shaft 16 of the connecting shaft extends from the first barrel sleeve 101. After opening the bean box cover, people can adjust the coarseness of the ground powder by rotating the connecting shaft or the extension shaft of the connecting shaft.

[0038] See also Figure 7-8 The motor seat 4 and the knife seat 5 are also connected in a detachable manner. The motor seat 4 has a first convex lock 40 and a second locking limit structure 41. The knife seat 5 is provided with a second convex lock 51 corresponding to the second locking limit structure 41, so that the motor seat 4 and the knife seat 5 form a detachable locking structure. When grinding beans is required, the motor seat 4 and the knife seat 5 form a snap connection relationship through the second locking limit structure 41 and the second convex lock 51. When it is necessary to disassemble and clean, the knife seat 5 is rotated in the opposite direction, so that the knife seat and the sharpening assembly thereon can be separated from the motor seat 4 to obtain an independent knife seat assembly, such as Figure 9-10 The knife seat assembly can be further disassembled. After the nut 17 is unscrewed and the gasket is removed, 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, and there is no dead corner for hygiene.

[0039] Before the coffee machine is started, the entire bean grinding mechanism is placed into the inner cavity of the connecting ring 3, and the motor cover is rotated to lock the mechanism and the connecting ring. At this time, a pair of electrodes on the mechanism contacts the terminals in the machine body, and the driving circuit of the first motor is connected, and the bean grinding work can begin.

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