[0031] The preferred embodiments of the present application will be described in detail with reference to the accompanying drawings.

[0032] A coffee bean grinding device comprises a bean cup assembly, a grinding device and a shell, wherein the bean cup assembly is assembled on the grinding device, and the grinding device is arranged inside the shell.Figure 1 As shown, the bean cup assembly includes a cup body 1, front and rear sliding doors 2, a drive block 4, and a bottom cover 5. The cup body 1 is fixed to the bottom cover 5. The front and rear sliding doors 2 and the drive block 4 are arranged sequentially from top to bottom between the bottom surface of the cup body 1 and the bottom cover 5. The upper part of the front and rear sliding doors 2 slides with the bottom surface of the cup body 1, and the lower part of the front and rear sliding doors 2 engages with the drive block 4. The drive block 4 and the bottom cover 5 are provided with communicating bean outlets. The grinding device is equipped with an automatic locking buckle 7, and the housing 10 is provided with locking pressing ribs 30. The grinding device is rotatably mounted inside the housing 10.

[0033] When the bean cup assembly is not installed on the grinding device, the front and rear sliding doors 2 close the bean outlet under the action of elasticity. When the bean cup assembly is installed on the grinding device, the grinding device is fixed to the drive block 4; the front and rear sliding doors 2 automatically open the bean outlet by rotating the cup body 1 in the forward direction, and close the bean outlet by rotating the cup body 1 in the reverse direction. After the bean outlet is opened, the cup body 1 continues to rotate in the forward direction, and the drive block 4 drives the grinding device to rotate relative to the housing 10. The automatic locking buckle 7 on the grinding device disengages from the locking pressing rib 30 on the housing and embeds into the bottom of the bean cup assembly.

[0034] like Figure 1 As shown, in this embodiment, the grinding device includes an adjuster cover 6, an automatic locking latch 7, a locking spring 8, and a grinding device body 9. Figure 3 As shown, the drive block 4 is provided with a fixed column 41, and the adjuster cover 6 of the grinding device is provided with a fixing hole 61 for inserting the fixed column 41. The drive block 4 is also provided with a sliding groove 42, and the front and rear sliding doors 2 are provided with a protruding post 21 for inserting into the sliding groove 42 of the drive block, as shown. Figure 4-1 As shown.

[0035] like Figure 4-2 As shown, the sliding door 2 has a sliding surface 22 on its upper surface. Figure 2 As shown, the bottom surface of the cup body 1 is provided with a guide rail 11 that cooperates with the sliding surface 22. In order to ensure that the sliding door 2 is always closed before the grinding device is installed, an elastic body 3 is provided between the front and rear sliding doors 2 and the cup body 1 to ensure that the front and rear sliding doors 2 close the bean outlet without external force. In this embodiment, the elastic body 3 is two tension springs.

[0036] In some embodiments, the adjuster cover 6 is fixedly assembled with the grinding device body to form an automatic locking cavity. The automatic lock can move up and down within the automatic locking cavity, inserting and retracting into the locking portion 51 provided on the bottom cover. For example... Figure 13As shown, the automatic lock 7 includes a cavity 74 for installing a lock spring, a locking position 71 for inserting into the locking notch, and a first inclined surface 73 and a first flat surface 72 for cooperating with the lock pressing rib position 30. When the locking position 71 is inserted into the locking notch 51, the bean cup assembly is locked on the grinding device, and the bean cup assembly and the grinding device can rotate synchronously. Conversely, when the locking position 71 is withdrawn from the locking notch 51, the bean cup assembly is unlocked. The lock spring provides a pushing force to the automatic lock 7, so that the locking position 71 can be inserted into the locking notch 51. The automatic lock cavity limits the direction and distance of movement of the automatic lock.

[0037] In some embodiments, the cooperating surface of the lock pressing rib position 30 and the automatic lock 7 includes a second inclined surface 301 and a second flat surface 302. When the automatic lock 7 is turned towards the lock pressing rib position 30, the first inclined surface 73 and the second flat surface 302 come into contact and slide relative to each other, as shown in Figure 11 , so that the locking position 71 is gradually withdrawn from the lock locking position 51. When the sliding of the two inclined surfaces ends, the first flat surface 72 and the second flat surface come into contact, and the locking position 71 cannot be automatically inserted into the locking notch 51. When the automatic lock 7 is turned away from the pressing rib position 30, the two flat surfaces gradually come out of contact, and the two inclined surfaces slide relative to each other, and the locking position 71 is gradually inserted into the locking notch 51 under the pushing force of the lock spring 8.

[0038] In some embodiments, as shown in Figure 8-1 , the cup body 1 is provided with a notch 15 at the bottom, and the shell 10 is provided with a notch 105 corresponding to the shape of the notch 15. Only when the two notches are aligned, the cup body 1 can be loaded into the shell or taken out of the shell.

[0039] In the assembled state, as shown in Figure 1 and Figure 3 , the two upright columns 61 of the adjuster cover 6 pass through the arc-shaped sliding groove 52 on the bottom cover 5 and are inserted into the fixed hole position 41 of the driving block 4, so that the adjuster cover 6 of the grinding device and the driving block 4 cannot move relative to each other. The bottom cover 5 and the cup body 1 are connected by screws and cannot move relative to each other. The driving block 4 is assembled between the gap between the bottom cover 5 and the cup body 1, and the driving block 4 and the cup body 1 can rotate relative to each other. As shown in Figure 5-1 and Figure 5-2 , the sliding surface on the top of the front and rear sliding door 2 cooperates with the sliding rail 11 on the bottom of the cup body 1, and the convex column 21 on the bottom surface is inserted into the arc-shaped sliding groove 42 of the driving block 4. Therefore, when the front and rear sliding door 2 rotates with the cup body 1, the convex column 21 will slide in the sliding groove of the driving block 4. The bottom surface of the cup body 1 and the front and rear sliding door can only slide relative to each other in the direction parallel to the contact surface, and they keep synchronous rotation. As shown in Figure 6-1 ,Figure 6-2 and Figure 7 As shown in the figure, the automatic lock 7 on the grinder body is blocked by the lock pressing rib 30 of the shell 10 and cannot be popped up, and the upper end surface of the automatic lock 7 is flush with the end surface of the adjuster cover 6.

[0040] When the coffee grinder is used, as shown in the figure, Figure 8-1 and 8-2 The cup 1 is inserted into the shell 10 with the notches corresponding to the shape of the shell. At this time, the column on the driving block 4 is inserted into the fixed hole position on the adjuster cover 6 through the arc-shaped sliding groove on the bottom cover 5. Rotate the cup 1 clockwise, the notches of the cup 1 corresponding to the shape of the shell 10 are misaligned, thereby limiting the vertical freedom of the cup 1, and the cup cannot be taken out of the shell 10. The rotation of the cup 1 drives the sliding door 2 and the bottom cover 5 to rotate clockwise at the same time, and the driving block 4 remains stationary under the constraint of the adjuster cover 6 of the grinder, and the sliding door 2 and the driving block 4 rotate relative to each other, as shown in FIG. 5, the front and rear sliding doors 2 slide in opposite directions on the arc-shaped sliding groove 42 of the driving block 4 and the guide rail 11 of the cup 1, respectively, and the bean cup assembly bottom is exposed after the bean cup assembly is rotated by a certain angle, as shown in FIG. 6. The bean outlet through hole covered by the sliding door 2. In this way, the coffee beans in the cup 1 can slide into the grinding area of the grinder. At this time, the protruding column 21 on the sliding door 2 inserted into the arc-shaped sliding groove 42 of the driving block 4 moves to the end of the sliding groove. Continue to rotate the cup 1 clockwise, the cup 1 will drive the driving block 4 and the grinder to rotate synchronously, and after rotating by a certain angle, the automatic lock 7 in the grinder is away from the lock pressing rib 12 of the shell 10, as shown in FIG. 7, the automatic lock 7 is popped up under the action of the spring 8, and the top of the automatic lock 7 is inserted into the lock locking position 51 on the bottom cover 5, as shown in FIG. 8, the cup and the grinder are locked together, and no matter the cup rotates clockwise or counterclockwise, the grinder will rotate synchronously. At this time, continue to rotate the cup 1 clockwise to enter the step of adjusting the fineness of the coffee powder. Figure 9 Figure 11 Figure 12 When the bean cup assembly needs to be removed, the cup 1 needs to be rotated counterclockwise, first the inclined surface 73 of the automatic lock 7 contacts the inclined surface of the lock pressing rib 20 of the shell 10, as shown in FIG. 9, and under the action of the rotating force, the automatic lock 7 is slowly pressed down and slides relative to the shell 10, until the automatic lock 7 is separated from the locking notch 51 on the bottom cover 5, continue to rotate the cup 1, the front and rear sliding doors 2 will gradually enter the closing state until completely closed, as shown in FIG. 10. When the notches of the cup 1 corresponding to the shape of the shell 10 are aligned, the bean cup assembly can be taken out. Since at this time the front and rear sliding doors 2 have completely covered the through hole at the bottom of the cup 11, it is ensured that the coffee beans in the cup 1 will not leak out when the bean cup assembly is taken out.

[0041] When the bean cup assembly needs to be removed, the cup 1 needs to be rotated counterclockwise, first the inclined surface 73 of the automatic lock 7 contacts the inclined surface of the lock pressing rib 20 of the shell 10, as shown in FIG. 9, and under the action of the rotating force, the automatic lock 7 is slowly pressed down and slides relative to the shell 10, until the automatic lock 7 is separated from the locking notch 51 on the bottom cover 5, continue to rotate the cup 1, the front and rear sliding doors 2 will gradually enter the closing state until completely closed, as shown in FIG. 10. When the notches of the cup 1 corresponding to the shape of the shell 10 are aligned, the bean cup assembly can be taken out. Since at this time the front and rear sliding doors 2 have completely covered the through hole at the bottom of the cup 11, it is ensured that the coffee beans in the cup 1 will not leak out when the bean cup assembly is taken out.
