[0030] When the customer needs to adjust the grinding coarseness, he issues an adjustment command, the drive motor 7 works, and the adjustment knob 3 is driven to rotate through the adjustment knob and the drive motor connector 4. The rotation of the adjustment knob 3 drives the grinder 1 to adjust the coarseness, and the scale value is displayed through the grinding dial 2. The slot-type photoelectric sensor 9 counts the number of rotations of the sensor paddle 5 to achieve the adjustment requirement.

[0031] Example 2

[0032] The device for automatically adjusting the grinding coarseness of coffee beans comprises a coffee bean grinder 1, a grinding coarseness dial 2, an adjustment knob 3, a connecting piece 4 between the adjustment knob and a driving motor, a sensor paddle 5, a paddle fixing screw 6, a driving motor 7, a driving motor fixing piece 8, a slot-type photoelectric sensor 9, a fixing screw 10, a slot-type sensor fixing piece 11 and a screw 12;

[0033] The grinding coarseness dial 2 and the adjustment knob 3 are fixedly mounted on the coffee bean grinder 1. The grinding coarseness dial 2 and the adjustment knob 3 are connected. The adjustment knob 3 is provided with a bevel gear 13. The grinding coarseness dial 2 is provided with a dial spur gear 14. A thread 18 is provided below the dial spur gear 14. The side wall of the coffee bean grinder is provided with a thread corresponding thereto. The bevel gear 13 is meshedly connected with the dial spur gear 14. The grinding coarseness dial 2 drives the cutter disc of the grinder to adjust the cutting gap, thereby adjusting the coarseness of the coffee beans. The degree of adjustment is preferably performed, and the blade disc includes a coarse blade disc 17, an upper fine blade disc 16, a lower fine blade disc 19, and a rotating blade 21. The dial spur gear 14 is sequentially connected to the coarse blade disc 17 and the upper fine blade disc 16 by bolts to form a whole; the lower fine blade disc 19 is arranged below the upper fine blade disc 16, and there is a gap 20 between the upper fine blade disc 16 and the lower fine blade disc 19 for dispensing coffee; the grinding coarse and fine dial 2 is provided with a scale display dial 15 for viewing the gear number value, so that the user can view the current coarse and fine gear conveniently. The sensor paddle 5 is installed on the adjustment knob and the drive motor connector 4 by the paddle fixing screw 6 to form a module. The drive motor 7 is installed on the drive motor fixing part 8, and the slot-type photoelectric sensor 9 is installed on the slot-type sensor fixing part 11 by the fixing screw 10 to form a module (counting function, through the screw 12) ， It is also mounted on the drive motor fixing member 8.

[0034] When the customer needs to adjust the grinding coarseness, an adjustment instruction is issued, and the drive motor 7 starts to work. The adjustment knob 3 is driven to rotate through the adjustment knob and the drive motor connector 4, and the adjustment knob 3 drives its bevel gear 13 to rotate, and then drives the dial spur gear 14 meshing with the bevel gear 13 to rotate, and the dial spur gear 14 drives the thread 18 to rotate. The thread 18 cooperates with the thread corresponding to the side wall of the coffee bean grinder, so that the upper fine knife disc 16 moves up and down relative to the side wall of the coffee bean grinder, and the lower fine knife disc 19 does not move in the up and down direction, and cooperates with the upper fine knife disc 16 to adjust the size of the upper and lower knife disc gap 20.

[0035] The rotating blade 21 and the lower fine blade disc 19 rotate synchronously to cut, and the two start and stop at the same time. In the coarse blade disc 17, the rotating blade 21 rotates and cuts to first coarsely grind the coffee beans; then, the coarsely ground coffee powder enters between the upper fine blade disc 16 and the lower fine blade disc 19, the upper fine blade disc 16 does not move, and the lower fine blade disc 19 rotates and cuts, and the two cooperate to finely grind the coffee beans. By adjusting the size of the gap 20 between the upper and lower blade discs, the purpose of adjusting the coarseness of the coffee beans is achieved. In addition, the scale value is displayed by the scale display disc 15 of the grinding scale disc 2.

[0036] The slot-type photoelectric sensor 9 counts the number of rotations of the sensor paddle 5. The slot-type photoelectric sensor 9 has a slot, and the sensor paddle 5 rotates through the slot. The sensor paddle 5 has a cutout, and the number of rotations is recorded by detecting the cutout to achieve the adjustment requirement. Each rotation of the slot-type photoelectric sensor 9 corresponds to 0.25 gears, that is, the slot-type photoelectric sensor 9 rotates 4 times to complete the adjustment of one gear. There are 6 gears in total, and the standard gear is set to 5.5 gears. The 5.5-6 gears are increasingly coarsely ground coffee beans, and the 5.5-2 gears are gradually finely ground coffee beans.

[0037] As an optional solution, this embodiment adds an origin detection switch (independently powered), that is, an origin detection sensor, to the coffee machine. When an abnormal condition occurs in the automatic adjustment device for the coarseness of coffee bean grinding, such as malfunction or sudden power failure, the origin detection switch sends a signal to the main controller of the coffee machine and sends out the current detection gear information. The main controller of the coffee machine gives a forward or reverse instruction based on the gear information, controls the motor to rotate, and thus controls the grinding coarseness dial 2 to return to the initial gear, which is convenient for the user to use next time.
