[0029] Refer to the following Figure 1-10 A coffee bean grinder powder outlet opening and closing structure is described according to some embodiments of the present application.

[0030] A powder outlet opening and closing structure of a coffee bean grinder comprises a machine body 1, a grinding unit 2 and an opening and closing structure 3. The opening and closing structure 3 is arranged on the machine body 1 below the grinding unit 2. After the grinding unit 2 grinds the coffee beans into coffee powder, the coffee powder is released from the powder outlet 6 through the opening and closing structure 3 and enters the coffee filter basket or brewing funnel so as to brew the coffee powder.

[0031] The opening and closing structure 3 includes a movable baffle 4 and a driving assembly 5. The movable baffle 4 is located below the powder outlet 6 of the grinding unit 2. The driving assembly 5 includes a meshing transmission mechanism 51 and a driving motor 50. The meshing transmission mechanism 51 includes a connecting rod 52, a gear 53 and a rack 54 which are sequentially connected in transmission. The connecting rod 52 is arranged on the output shaft of the driving motor 50 as the input end of the meshing transmission mechanism 51, and the rack 54 is connected to the movable baffle 4 as the output end of the meshing transmission mechanism 51. A clamping groove 7 is arranged at the tail of the movable baffle 4, and a clamping block 8 matching the clamping groove 7 is arranged at the head of the rack 54. The rack 54 can be connected to the movable baffle 4 by clamping the clamping block 8 into the clamping groove 7. When the driving motor 50 rotates, its output shaft drives the connecting rod 52 to rotate, the connecting rod 52 drives the gear 53, the gear 53 drives the rack 54 to move forward and backward and drives the movable baffle 4 to move forward and backward, thereby opening and closing the powder outlet 6.

[0032] A pendulum block 9 is arranged on the connecting rod 52. The pendulum block 9 swings between a first position and a second position driven by the driving motor 50. When swinging to the first position, the pendulum block 9 triggers a first micro switch 11. When rotating to the second position, the pendulum block 9 triggers a second micro switch 10. The first micro switch 11 and the second micro switch 10 respectively correspond to the moving positions of the movable baffle 4 when the powder outlet 6 is completely closed and opened, and can effectively and accurately realize the opening and closing of the powder outlet 6, avoiding powder leakage due to inadequate closing and poor powder feeding due to insufficient opening.

[0033] Slide grooves 12 are symmetrically arranged on the body 1 on both sides of the movable baffle 4, and the movable baffle 4 is arranged in the slide grooves 12. Under the drive of the meshing transmission mechanism 51, the movable baffle 4 moves forward and backward along the slide grooves 12, ensuring the straightness and smoothness of the movement; at the same time, wing plates 13 extend on both sides of the rack 54, and the width of the wing plates 13 is equivalent to the width of the movable baffle 4. Both ends of the wing plates 13 are located in the slide grooves 12. When the meshing transmission mechanism 51 drives the movable baffle 4 to move forward and backward along the slide grooves, the wing plates 13 also move synchronously with the movable baffle, thereby improving the stability of the synchronous movement of the rack 54 and the movable baffle.

[0034] 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.
