For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to the specific circumstances.

[0028] A grinding system for a coffee grinder, see Figure 1-5 , including a bean grinder and a bean grinding assembly 100 arranged on the bean grinder, the bean grinder is a device for grinding coffee beans or other beans, the bean grinder is provided with a shell 100 and a bean box 300 connected to the shell 200, the bean box 300 can be connected to the bean grinding assembly 100 and coffee beans can fall into the bean grinding assembly 100, the shell 100 is provided with an opening on the top, the bean grinding assembly 100 is arranged on the shell 200 and corresponds to the position of the opening, the bean box 300 is fixed on the shell 100 and docked with the bean grinding assembly 100, so that the coffee beans falling in the bean box 300 can enter the bean grinding assembly 100 for grinding. The bean grinding assembly 100 includes a base 110, which is fixed in the housing 100. The base 110 is provided with a cylindrical grinding groove 120, and a cutter head 121 is provided in the grinding groove 120. When the cutter head 121 rotates, it can grind nearby coffee beans; the outer side of the grinding groove 120 is connected to an inner ring 130 that can move up and down, and the inner ring 130 is sleeved on the outer side of the grinding groove 120. The outer side of the inner ring 130 is provided with an outer ring 140 that can drive it to move up and down. An adjusting ring 150 is connected to 140 and can drive it to rotate horizontally. When the outer ring 140 rotates horizontally, it can drive the inner ring 130 to move up and down. A gear indicator ring 160 is connected above the adjusting ring 150. A cutter disc 170 is detachably provided in the inner ring 130. The cutter disc 170 is embedded in the grinding groove 120. After the coffee beans in the bean box 300 fall into the bean grinding assembly 100, they will enter the cutter disc 170, and the cutter head 121 rotates to cooperate with the cutter disc 170 to grind the coffee beans.

[0029] Furthermore, a feeding trough 122 is formed between the inner side of the cutter disc 170 and the cutter head 121, and the size of the feeding trough 122 is controlled as the cutter disc 170 moves up and down; the outer side of the cutter head 121 and the inner side of the cutter disc 170 are inclined structures, and when the cutter disc 170 moves vertically up and down, the size of the feeding trough 122 (i.e., the distance between the outer side of the cutter head 121 and the inner side of the cutter disc 170) will change, so that coffee powder of different sizes produced after the coffee beans are ground by the cutter head 121 and the cutter disc 170 can pass through the feeding trough 122. When the chute 122 is small, coffee powder with larger particles cannot fall from the chute 122, and the coffee powder can only continue to be ground into smaller particles and then fall through the chute 122; when the chute 122 is large, coffee powder with a lower grinding degree (i.e., larger particles) can also fall through the chute 122; therefore, the up and down movement of the knife disc 170 controls the size change of the chute 122 to control the size of the coffee powder falling from the chute 122, thereby achieving the grinding degree of the coffee powder, that is, controlling the particle size of the coffee powder.

[0030] Furthermore, the inner ring 130, the outer ring 140, the adjustment ring 150, the blade disc 170, and the gear indicator ring 160 in the grinding assembly 100 are convenient to combine with each other, which is convenient for installation during production, and the above components are closely coordinated to control the size of the drop chute 122 to control the grinding degree of the coffee powder, so that the user can accurately adjust the grinding degree of the coffee beans and it is convenient to use.

[0031] Furthermore, the bean grinding assembly 100 is provided with a motor 180 which is connected to and drives the cutter head 121 to rotate. The cutter head 121 forms an angle with the blade provided on the inner side of the cutter disc 170. The blade is evenly distributed on the inner side of the cutter disc 170. The surface of the cutter head 121 has a spiral blade. The structure of the blade and the blade is not shown in the accompanying drawings. When the cutter head 121 rotates, it cooperates with the blade to grind the coffee beans in the cutter disc 170. The angle formed by the two is conducive to the grinding of the coffee beans. After the coffee beans are ground into powder smaller than the size of the drop chute 122, they fall to the drop chute 122 provided on the base 110. After the user adjusts the degree of grinding of the coffee powder, the coffee beans are ground to a corresponding degree on the cutter disc 170 and fall through the drop chute 122. The drop chute 111 is connected to the coffee powder outlet provided on the shell 200, and finally the coffee powder is discharged from the coffee grinder through the drop chute 111. The user uses a container to catch the coffee powder for use.

[0032] Furthermore, a first limiting protrusion 123 of a vertical structure is provided on the outer side of the grinding groove 120, and a first limiting groove 131 matching the first limiting protrusion 123 is provided on the inner side of the inner ring 130. The inner ring 130 is embedded in the first limiting protrusion 123 through the first limiting groove 131 to be sleeved on the grinding groove 120 and restricted from horizontal rotation. In this embodiment, the first limiting protrusion 123 is provided on both sides of the grinding groove 120. The first limiting protrusion 123 is two strip-shaped protrusions longitudinally provided on the outer side of the grinding groove 120, but the shape and size of the first limiting protrusion 123 are not limited to this embodiment. The setting of 123 and the first limiting groove 131 facilitates the inner ring 130 to be aligningly sleeved on the grinding groove 120 during processing, and at the same time limits the inner ring 130 to be installed on the grinding groove 120 so that it can only move vertically up and down along the first limiting groove 131, and cannot rotate horizontally, thereby ensuring the movement stability of the inner ring 130; a thread groove 141 is provided on the inner side of the outer ring 140, and a thread protrusion 132 matching the thread 141 is provided on the outer side of the inner ring 130. Through the cooperation of the thread protrusion 132 and the thread groove 141, when the outer ring 140 rotates while maintaining a horizontal height, the inner ring 130 will be driven to move up and down.

[0033] Furthermore, a plurality of second limiting grooves 142 are provided on the outer side of the top of the outer ring 140, and a plurality of second limiting protrusions 151 matching the second limiting grooves 142 are provided on the inner side of the adjusting ring 150. The adjusting ring 150 is embedded in the second limiting grooves 142 through the second limiting protrusions 151 to limit the connection with the outer ring 150. The second limiting grooves 142 are evenly distributed on the outer side of the top of the outer ring 142 to form a serrated shape, which is convenient for the second limiting protrusions 151 to be embedded therein, and is convenient for installation during production. The adjusting ring 150 and the outer ring 140 form a limiting connection through the second limiting protrusions 151 and the second limiting grooves 142, so that the outer ring 140 can be driven to rotate when the adjusting ring 150 rotates horizontally; the adjusting ring 150 is provided with two upwardly protruding connecting columns 152, and the top of the outer shell 100 is provided with a column groove 101. The adjusting ring 150 passes through the column groove 101 through the connecting column 152 and is connected to the gear indicator ring located above the outer shell 100. 160, when the adjusting ring 150 rotates, the connecting column 152 moves within the range of the column groove 101, and the column groove 101 can limit the rotation range of the adjusting ring 150; a scale for displaying the degree of grinding is provided on the outer side of the gear indicator ring 160, and the user can judge the degree of grinding set by the bean grinding assembly 100 through the scale. When the bean grinding assembly 100 is processed and installed, the gear indicator ring 160 is installed so that the scale corresponds to the size of the blanking groove 122 to ensure the accuracy of the scale; the gear indicator ring 160 is located at the top of the housing 200, and the gear indicator ring 160 is fixedly connected to the connecting column 152 by screws. When the user rotates the gear indicator ring 160 to the corresponding scale, the gear indicator ring 160 drives the adjusting ring 150 and the outer ring 140 to rotate, and the inner ring 130 moves up and down, and the knife disc 170 located on the inner ring 130 moves to the corresponding vertical height, so that the size of the blanking groove 122 matches the scale.

[0034] Furthermore, a retaining ring 171 extending outward is provided on the top of the cutter disc 170, and a groove 133 matching the retaining ring 171 is provided on the top of the inner ring 130. When the cutter disc 170 is embedded in the inner ring 130, the groove 133 supports the retaining ring 171, so that the cutter disc 170 can be stably placed in the inner ring 130. The retaining ring 171 is provided with two third limiting grooves 172, and the inner side of the groove 133 is provided with a third limiting protrusion 134 matching the third limiting groove 172. After the cutter disc 170 is placed on the inner ring 130, it is rotated horizontally so that the third limiting protrusion 134 sinks into the third limiting groove 172, so that the cutter disc 170 is further stably connected to the inner ring 130, ensuring the stable movement of the cutter disc 170 when the inner ring 130 moves up and down, and making the size control of the blanking groove 122 more accurate.

[0035] Furthermore, the blade disc 170 is provided with a flippable lifting ear 173, and the user can lift the blade disc 170 through the lifting ear 173, so as to facilitate the disassembly and assembly of the blade disc 170 from the bean grinding assembly 100 and facilitate cleaning; two locking bars 122 are fixed on the base 110, and the locking bars 122 are semi-annular structures and are fixed to the base 110 by screws. A convex ring 143 matching the locking bars 122 is provided on the outer side of the outer ring 140, and the locking bars 122 limit the vertical movement of the outer ring 140 by cooperating with the convex ring 143.
