[0031] And the sieve hopper 16 is provided with a filter plate 110 at one end, the filter plate 110 is used for sieving the coffee powder after grinding, and a grinding cylinder 111 is placed on the sieve hopper 16, the grinding cylinder 111 is provided with a grinding cavity (not shown in the figure) formed therein, the grinding cavity is provided with a concave-convex surface 112, and a butt joint block 114 is fixedly installed on both sides of the grinding cylinder 111, and a limiting block 113 limiting the butt joint block 114 is fixedly installed on the top plate 14, the limiting block 113 is provided with an installation slot (not shown in the figure), and the grinding cylinder 111 is adapted to be inserted into the installation slot through the two sets of butt joint blocks 114, and the grinding cylinder 111 is provided with a gap between the bottom surface and the filter plate 110 for the coffee powder to pass through;

[0032] And a grinding assembly 2 is installed on the top plate 14, the grinding assembly 2 comprises a first sealing cover 21 installed on the top plate 14 through a fastener, the first sealing cover 21 is semicircular, and a portion of the first sealing cover 21 is pressed on the grinding cylinder 111, a rotating shaft 22 is bearingly installed on the first sealing cover 21, a grinding part 23 is fixedly installed on one end of the rotating shaft 22, the grinding part 23 is provided with a concave-convex block (not shown in the figure) matching the concave-convex surface 112, the concave-convex block extends into the grinding cavity, a handle 24 is fixedly installed on the other end of the rotating shaft 22, and the concave-convex block and the concave-convex surface 112 have a gap for the coffee beans to enter, and the handle 24 is adapted to drive the rotating shaft 22 to rotate to grind the coffee beans;

[0033] First, the sieve hopper 16 is installed. The insertion blocks 17 on both sides of the sieve hopper 16 are aligned with the opening slots 19 of the mounting holes 15 on the top plate 14 of the storage box 11, and then the sieve hopper 16 is pushed so that the insertion blocks 17 pass through the opening slots 19 and are clamped in the insertion slots of the adaptive blocks 18 fixedly installed on the inner wall top surface of the storage box 11, so that the sieve hopper 16 is stably installed on the mounting holes 15 of the top plate 14.

[0034] Then the grinding cylinder 111 is installed. The grinding cylinder 111 is placed on the screening hopper 16, the abutting blocks 114 on both sides of the grinding cylinder 111 are aligned with the installation grooves of the limiting blocks 113 fixedly installed on the top plate 14, and then the abutting blocks 114 are inserted into the installation grooves, so that the positioning and installation of the grinding cylinder 111 are completed. At this time, the gap for the coffee powder to pass through is formed between the bottom surface of the grinding cylinder 111 and the filter plate 110.

[0035] The first sealing cover 21 is installed on the top plate 14 through fasteners, and the first sealing cover 21 is pressed on the grinding cylinder 111 at some positions, so as to further fix the grinding cylinder 111. Meanwhile, the rotating shaft 22 is installed on the first sealing cover 21 through a bearing, so that the rotating shaft 22 can rotate flexibly, and the concave-convex blocks of the grinding part 23 at one end of the rotating shaft 22 extend into the grinding cavity of the grinding cylinder 111 and correspond to the concave-convex surface 112 of the grinding cavity.

[0036] The rotating handle 24 is held and rotated, the rotating handle 24 drives the rotating shaft 22 to rotate, and then the grinding part 23 at one end of the rotating shaft 22 rotates. Since there is a gap between the concave-convex blocks of the grinding part 23 and the concave-convex surface 112 of the grinding cavity of the grinding cylinder 111, the coffee beans remaining in the screening hopper 16 will gradually enter the gap under the action of gravity. In the process of rotation of the grinding part 23, the concave-convex blocks and the concave-convex surface 112 are extruded, rubbed and sheared with each other, so that the coffee beans entering the gap are ground into coffee powder.

[0037] After the ground coffee powder comes out of the grinding cylinder 111, it will fall on the filter plate 110 through the gap between the bottom surface of the grinding cylinder 111 and the filter plate 110, and the filter plate 110 will screen the coffee powder again. Some larger particles of powder or coffee beans that are not sufficiently ground will be intercepted by the filter plate 110, and the fine coffee powder meeting the requirements will pass through the filter plate 110 and fall into the storage box 11. When the coffee powder needs to be taken out, the collection drawer 12 slidingly inserted on the side of the storage box 11 is pulled out, so that the coffee powder in the collection drawer 12 can be collected and subsequently processed.

[0038] In order to avoid the coffee powder flying during the grinding of the coffee beans, as shown in FIGS. Figure 2 and Figure 4 A second sealing cover 25 is hinged to the side of the top plate 14, and the second sealing cover 25 is adapted to rotate along the hinge with the top plate 14 to abut with the first sealing cover 21 to form an overall cover structure. It should be noted that the contact areas of the second sealing cover 25, the first sealing cover 21 and the top plate 14 are all provided with flexible pads, so that when the second sealing cover 25 rotates along the hinge, the first sealing cover 21 abuts with the second sealing cover 25 by extruding the flexible pads;

[0039] Meanwhile, the second sealing cover 25 is fixedly installed with a butt joint angle plate 26, and the first sealing cover 21 is installed with a butt joint unit, which comprises a fixed part 28 fixedly installed on the first sealing cover 21, a round hole (not shown in the figure) is formed in the fixed part 28, a torsion spring 210 is fixedly installed on the inner wall bottom end of the round hole, a rotating part 29 is fixedly installed on one end of the torsion spring 210, one end of the rotating part 29 is in bearing connection with the inner wall bottom end of the round hole, a limiting part 211 is fixedly installed on the rotating part 29, and a through slot 27 adapted to the limiting part 211 is formed in the butt joint angle plate 26;

[0040] It should be noted that, in the initial state, the limiting part 211 is perpendicular to the through slot 27, so when the second sealing cover 25 is to be fixedly butted with the first sealing cover 21, the second sealing cover 25 is rotated along the hinge with the top plate 14, so that the first sealing cover 21 is butted with the second sealing cover 25 by pressing the flexible pad, at this time, the rotating part 29 is held and rotated by 90 degrees, so that the limiting part 211 corresponds to the through slot 27, then the first sealing cover 21 and the second sealing cover 25 are pressed to closely adhere to each other, and then the rotating part 29 is loosened, at this time, the rotating part 29 is reset again under the action of the torsion spring 210, and the rotating part 29 is in a state of being perpendicular to the through slot 27, so as to limit the first sealing cover 21;

[0041] When it is ready to start grinding, in order to prevent the coffee powder from flying around, the second sealing cover 25 is rotated along the hinge with the top plate 14. Since the contact areas of the second sealing cover 25 with the first sealing cover 21 and the top plate 14 are all provided with flexible pads, during the rotation process, the first sealing cover 21 will press the flexible pad to butt with the second sealing cover 25, forming a relatively sealed space.

[0042] After the butt joint is completed, the butt joint unit is operated to be fixed. The rotating part 29 is held and rotated by 90 degrees, so that the limiting part 211 on the rotating part 29 is rotated from the initial state of being perpendicular to the through slot 27 on the butt joint angle plate 26 to correspond to the through slot 27.

[0043] Then the first sealing cover 21 and the second sealing cover 25 are pressed to closely adhere to each other. At this time, the rotating part 29 is loosened, and the rotating part 29 is reset again under the action of the torsion spring 210 to return to a state of being perpendicular to the through slot 27. In this way, the limiting part 211 is clamped in the through slot 27, and the first sealing cover 21 and the second sealing cover 25 are limited, so that they are firmly butted together to form an overall cover structure, effectively preventing the coffee powder from overflowing.

[0044] After the sealing cover is fixed, the rotating handle 24 is held and rotated, the rotating shaft 22 is driven to rotate by the rotating handle 24, and then the grinding part 23 at one end of the rotating shaft 22 is rotated. There is a gap between the concave-convex blocks of the grinding part 23 and the concave-convex surface 112 of the grinding cylinder 111, and the coffee beans remaining in the screening hopper 16 gradually enter the gap under the action of gravity. During the rotation of the grinding part 23, the concave-convex blocks and the concave-convex surface 112 are extruded, rubbed and sheared, and the coffee beans are ground into coffee powder.

[0045] After the ground coffee powder comes out of the grinding cylinder 111, it falls on the filter plate 110 through the gap between the bottom surface of the grinding cylinder 111 and the filter plate 110. The filter plate 110 re-screens the coffee powder, and the larger particles of the powder or the insufficiently ground coffee beans are intercepted, and the fine coffee powder meeting the requirements falls into the storage box 11.

[0046] After the grinding work is completed, when the coffee powder needs to be taken out, the sealing cover is first opened by operating the docking unit. The rotating part 29 is held and rotated by 90 degrees, the limiting part 211 corresponds to the through slot 27, the restriction on the first sealing cover 21 and the second sealing cover 25 is released, then the second sealing cover 25 is turned and opened along the hinge, and finally the collection drawer 12 slidingly inserted on the side of the storage box 11 is pulled out, and the coffee powder in the collection drawer 12 is collected and processed subsequently.

[0047] The device uses modular design for each component. The screening hopper 16 can be quickly and stably installed on the top plate 14 of the storage box 11 through the cooperation of the plug-in block 17, the open slot 19 and the adapter block 18; the grinding cylinder 111 is precisely positioned through the installation slot of the adapter block 18 and the limiting block 113. The first sealing cover 21 is installed on the top plate 14 by means of fasteners, further fixing the grinding cylinder 111. This assembly method not only facilitates installation, but also ensures the stability of the connection of each component.

[0048] The second sealing cover 25 is docked with the first sealing cover 21 through the flexible pad block, forming a relatively sealed space, which greatly reduces the flying of coffee powder during grinding. Not only does it keep the working environment clean, but it also avoids waste of coffee powder and reduces the potential risk of inhaling coffee powder to human health.

[0049] The docking unit realizes the convenient locking and unlocking of the first sealing cover 21 and the second sealing cover 25 through the synergistic effect of the rotating part 29, the torsional spring 210, the limiting part 211 and the through slot 27. This design ensures that the sealing cover always closely fits during grinding, enhancing the sealing effect.

The present application can have various modifications and changes for those skilled in the art. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
