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.

[0028] Refer to the following Figures 1-8 A bean cup locking structure of a bean grinding device according to some embodiments of the present application is described.

[0029] A bean cup locking structure for a bean grinding device includes a body 17 and a bean cup assembly. The bean cup locking structure comprises a bean cup seat 2, a fixing frame 11, a push rod 18, and a push rod pressure plate 19. A first countersunk hole 20 is defined at the bottom of the bean cup seat 2. A second spring 21 is mounted on the push rod 18 and installed within the first countersunk hole 20. A third through-hole 22 is defined in the center of the push rod pressure plate 19. The push rod pressure plate 19 presses against the push rod 18 and is screwed to the bottom of the bean cup seat 2. The lower end of the push rod 18 extends through the third through-hole 22. A second countersunk hole 23 is defined on the fixing frame 11. A first and second screw buckles 24 and 25 of varying sizes are provided on the periphery of the bean cup seat 2. The fixing frame 11 is provided with a first and second annular protrusions 29 and 30. The bean cup seat 2 is screwed to the fixing frame 11 via the screw buckles and the protrusions. The bean cup seat 2 is screwed to the bottom of the bean cup 1.

[0030] During use, first fill the bean cup 1 with coffee beans, then screw it together with the bean cup holder 2 onto the fixing frame 11. The first and second screw buckles 24, 25 on the bean cup holder 2 correspond to the first and second annular protrusions 29, 30 on the fixing frame 11, respectively. During the screwing process, the lower end of the push rod 18 slides against the fixing frame 11 until it reaches the second countersunk hole 23 of the fixing frame 11. Due to the elastic force of the second spring 21, the lower end of the push rod 18 extends and abuts against the second countersunk hole 23, achieving a locking effect. With this locking structure, when the bean grinder is in operation, the vibration generated is not sufficient to cause the bean cup 1 and bean cup holder 2 to dislodge, thereby eliminating safety hazards and improving the safety of the bean grinding device.

[0031] The bean grinding device further includes a rotating ring 28 , which is mounted below the fixing frame 11 and can rotate freely; the fixing frame 11 is mounted above the machine body 17 by screws.

[0032] A switch door 3 is installed between the bean cup 1 and the bean cup holder 2. A linear sliding pair 6 is provided between the bean cup holder 2 and the switch door 3, allowing the switch door 3 to slide open and close the bean inlet. Specifically, the linear sliding pair 6 consists of a slide rail 7 on the bean cup holder 2 and a linear groove 8 at the bottom of the switch door 3. The bean cup 1 is pressed onto the switch door 3, with the bottom edge of the bean cup 1 passing over the switch door 3 and connected to the edge of the bean cup holder 2 via screws. The switch door 3 has a first through-hole 9 and a rectangular groove 14 at its bottom. The first through-hole 9 connects to one end of a first spring 10, the other end of which connects to a protruding post on the edge of the bean cup holder 2. The bean cup holder 2 is mounted on the grinder's fixed bracket 11. The bean cup holder 2 has a second through-hole 13 and a second protrusion 26 on the fixed bracket 11. The second protrusion 26 passes through the second through-hole 13 of the bean cup holder 2 and engages with the rectangular groove 14 at the bottom of the switch door 3. In the natural state, the first spring 10 pulls the switch door 3 to close it. When the bean cup 1 and the bean cup holder 2 are mounted on the fixing frame 11 and rotated and fixed, the second protrusion 26 on the fixing frame 11 engages the rectangular groove 14 of the switch door 3, preventing the switch door 3 from moving. As a result, the bean cup holder 2 rotates relative to the switch door 3 and produces relative displacement, the bean inlet opens, and beans can enter.

[0033] There is a circular groove 15 on the bean cup holder 2, and a sealing ring 16 is installed on the circular groove 15. The bottom of the switch door 3 presses the sealing ring 16, and the three fit tightly together, so that the internal structure of the bean cup 1 and the bean cup holder 2 is in a completely sealed state, thereby preventing coffee from entering the bean cup holder 2 through the gap when the bean grinder is working and causing contamination, thereby improving the hygienic condition of the bean grinder when in use and benefiting the health of the user.

[0034] 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.
