[0033] Please see Figure 1 , Figure 4 and Figure 7The coffee bean grinding device of this embodiment includes an adjustment assembly 2 disposed within a housing 1. The adjustment assembly 2 includes an adjustment disc 21 connected to the first grinding disc 5. The adjustment assembly 2 also includes a rotating component 22, a connecting component 23 connected to the rotating component 22, and an adjustment ring 24 connected to the connecting component 23. When the rotating component 22 is rotated, the adjustment ring 24 rotates along with the rotating component 22 under the action of the connecting component 23. The surface of the rotating component 22 also has a scale 221 for easy recording of the rotation value of the rotating component 22.

[0034] For further information, please refer to [link / reference]. Figure 4 , Figure 9 and Figure 10 The adjusting ring 24 is fitted to the adjusting disk 21. The adjusting ring 24 has four uniformly distributed first protrusions 241 on its surface near the adjusting disk 21. Similarly, the adjusting disk 21 has four uniformly distributed first recesses 211 on its surface near the adjusting ring 24. The first protrusions 241 act on the first recesses 211 to adjust the adjusting disk 21 along a second direction. In this embodiment, the second direction is the length direction of the housing 1, which is parallel to the horizontal ground. The first recesses 211 are arc-shaped, and their depth increases or decreases uniformly in a clockwise direction relative to the surface of the adjusting disk 21; that is, the first recesses 211 become deeper or shallower in a clockwise direction. The adjusting assembly 2 also includes a sealing member 25, which is disposed at one end of the housing 1 and fixed to the adapter 23, thereby ensuring the stability of the adjusting assembly 2 within the housing 1.

[0035] Please continue reading. Figure 4 and Figure 7The device further includes a detection component 3 disposed within the housing 1. The detection component 3 includes a connecting rod 31, one end of which is connected to the adjusting disk 21. The detection component 3 also includes a sensor 32 and an elastic element 33. One end of the connecting rod 31 is also connected to the elastic element 33, and one end of the elastic element 33 is also connected to the sensor 32. Furthermore, when the adjusting disk 21 rotates, causing the first protrusion 241 to move within the first recess 211, under the action of the first protrusion 241 of the adjusting ring 24 and the elastic element 33, the adjusting disk 21 adjusts along a second direction, thereby causing the first grinding disk 5 to adjust along a second direction, controlling the gap between the first grinding disk 5 and the second grinding disk 6, thus achieving the grinding of coffee beans. Specifically, the elastic element 33 ensures that the connection between the connecting rod 31 and the adjusting disk 21 is tightly fitted. When the first grinding disk 5 moves towards the second grinding disk 6, the adjusting disk 21 increases the pressure on the connecting rod 31, thereby compressing the elastic element 33. The sensor 32 then accurately measures and feeds back the movement distance of the adjusting disk 21.

[0036] Please continue reading. Figure 4 , Figure 7 and Figure 8 The device further includes a power assembly 4 disposed within the housing 1. The power assembly 4 includes a rotating shaft 41 with a bearing portion 411 connected to the second grinding disc 6. When the rotating shaft 41 rotates, it drives the second grinding disc 6 to rotate for grinding. The power assembly 4 also includes a mover 42, a first fixing member 43, a second fixing member 44, and a coil 45. The mover 42 is fixed to the rotating shaft 41 to drive its rotation. The coil 45 is sleeved on the mover 42 and provides power to the mover 42 under electromagnetic influence. The first fixing member 43 and the second fixing member 44 are connected to the housing 1, and the rotating shaft 41 passes through them, securing it in place.

[0037] For further information, please refer to [link / reference]. Figure 11 and Figure 12One end of the rotating shaft 41 is fitted to the adjusting disk 21 and partially located within the adjusting disk 21. The portion of the rotating shaft 41 located within the adjusting disk 21 also has a feeding thread 412. Rotation of the rotating shaft 41 drives the feeding thread 412 to transport coffee beans. The other end of the rotating shaft 41 passes through the first fixing member 43 and the second fixing member 44. A second protrusion 413 is provided on the support portion 411 near the first fixing member 43, and a second recess 431 is provided on the first fixing member 43 near the support portion 411. The second protrusion 413 engages with the second recess 431. Preferably, in this embodiment, the second protrusion 413 and the second recess 431 are multiple concentric annular structures of different diameters, thus providing a good seal for the coffee bean grinding area.

[0038] Please continue reading. Figure 1 , Figure 4 , Figure 7 and Figure 8 The device also includes a feeder 8 connected to the housing 1. The feeder 8 has an inlet hole 81 on its surface. Inside the feeder 8, a first guide plate 82 and a second guide plate 83 are arranged in an alternating pattern. The first guide plate 82 and the second guide plate 83 buffer the coffee bean feed, providing good protection for the device. The adjusting disc 21 has a transfer hole 212. The inlet hole 81 connects to the transfer hole 212, which in turn connects to the first grinding disc 5 and the second grinding disc 6, thus allowing for feeding. When coffee beans enter the adjusting disc 21 through the transfer hole 212, the rotation of the shaft 41, along with the action of the feed thread 412, conveys the coffee beans towards the first grinding disc 5, allowing them to be ground between the first grinding disc 5 and the second grinding disc 6.

[0039] Please continue reading. Figure 5 and Figure 6A discharge hole 101 is formed at the lowest point of the surface of the housing 1 along a first direction, near the first grinding disc 5 and the second grinding disc 6. The device also includes a cleaning component 7 that cooperates with the discharge hole 101. In this embodiment, the first direction is perpendicular to the horizontal ground. The cleaning component 7 includes a feeder 71, the surface of which has a drop hole 711 that cooperates with the discharge hole 101. A rotatable drive component 72 is also provided inside the feeder 71, and the drive component 72 is connected to a scraper 73 that cooperates with the edge of the discharge hole 101. The ground coffee powder will fall from the discharge hole 101 through the gap between the first grinding disc 5 and the second grinding disc 6, and it is difficult to avoid coffee powder remaining on the edge of the discharge hole 101. The scraper 73 effectively cleans the coffee powder remaining on the edge of the discharge hole 101.

[0040] Furthermore, a first wire hole 102 is provided at the lowest point along the first direction on the surface of the housing 1, and a second wire hole 712 is provided on the surface of the dispenser 71. Wires pass through the first wire hole 102 and the second wire hole 712 to connect to the drive unit 72. The surface of the dispenser 71 is also uniformly provided with through holes 713. When ground coffee powder accidentally falls onto the surface of the drive unit 72 inside the dispenser 71, the rotation of the drive unit 72 can fling the fallen coffee powder out through the through holes 713, thereby ensuring the cleanliness of the inside of the dispenser 71.

[0041] Please continue reading. Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 6 The device further includes a support member 9 and a base 10, with the housing 1 connected to the base 10 via the support member 9. A control member 11 is mounted on the surface of the support member 9. Preferably, the control member 11 is used to press a switch to control the device, and can also be rotated to adjust the power of the mover 42 to change the rotational speed of the shaft 41. The surface of the base 10 has a display screen 1001, which displays functional parameters such as the rotational speed of the shaft 41 and the values ​​fed back by the sensor 32. Wires can be routed through the interior of the support member 9 and the interior of the base 10 to connect the control member 11 and the display screen 1001, respectively.

[0042] For further information, please refer to [link / reference]. Figure 4The housing 1 also includes a heat dissipation assembly 12 comprising a fan 121 and an air outlet plate 122. The air outlet plate 122 is located at one end of the housing 1, and the heat from grinding coffee beans is dissipated through the fan 121, ensuring the safety of the equipment during operation. The housing 1 also contains a circuit board 13, which is electrically connected to the sensor 32, the actuator 42, the drive component 72, the fan 121, the control component 11, and the display screen 1001, thereby enabling intelligent use of the equipment.
