[0048] 3. When the fixed block 63 in the cup holder 6 rotates to the position of the limit switch 76 serving as the end switch, the side of the fixed block 63 touches the limit switch 76, closing the limit switch 76. At this time, the controller receives the signal indicating that the limit switch 76 is closed and controls the drive motor 74 to stop working. The drive motor 74 stops rotating, causing the tray 61 of the cup holder 6 to stop below the grinder 2 with the coffee filter cup 4 and the coffee cup 5.

[0049] 4. At this time, the controller controls the bean grinder 2 to release the coffee powder, and the bean grinder 2 releases the coffee powder onto the coffee filter cup 4;

[0050] 5. After the bean grinder 2 has released all the coffee grounds, the controller controls the drive motor 74 to be powered on. The drive motor 74 rotates clockwise, driving the drive block 75 and the fixed block 63 to rotate, thereby driving the entire cup holder 6 to rotate clockwise.

[0051] 6. When the fixed block 63 rotates to the position of the limit switch 76 serving as the starting switch, the side surface of the fixed block 63 contacts the limit switch 76, closing the starting limit switch 76. At this point, the controller receives the signal indicating that the limit switch 76 is closed and controls the drive motor 74 to stop. The drive motor 74 stops rotating, causing the tray 61 of the cup holder 6 to stop at the starting position with the coffee filter cup 4 and the coffee cup 5. At this point, the coffee filter cup 4 and the coffee cup 5 are stopped below the sprinkler 3.

[0052] 7. At this time, the controller controls the water pump 11 to start working, pumping water from the water tank 8 into the water pump 11 through the pipe. The water pump 11 inputs the water into the water heater 14 through the pipe for heating. The water heated by the water heater 14 is input to the water inlet of the sprinkler 3 through the pipe. The sprinkler 3 sprinkles the water reaching the set temperature into the coffee filter cup 4 and onto the coffee grounds in the coffee filter cup 4. The water sprinkled on the coffee grounds then flows into the coffee cup 5. At this point, the entire working process of the coffee machine, from grinding coffee beans to brewing coffee, is completed.

[0053] The utility model only requires that coffee beans be placed on the bean grinder of the coffee machine, an appropriate amount of water be added to the water tank, and the required functions be set on the base. Once the start button is pressed, the coffee machine will automatically complete the entire coffee making process from grinding the coffee beans to brewing the coffee. The entire process simulates the manual coffee brewing process and does not require manual supervision. There is no need to manually move the coffee cup from the sprinkler to the bottom of the grinder to fill the coffee powder, nor is there any need to manually move the coffee cup back to the bottom of the sprinkler. This brings a brand new experience and comfortable enjoyment to consumers who love brewing coffee. The utility model has the advantages of simple and convenient operation, professionalism, safety, comfort, low cost, and strong reliability.
