(When viewed from the axis), the motor shaft rotates counterclockwise to drive the driving block 131 to rotate. The rotation of the driving block 131 drives the rotation of the fixed block 122, thereby driving the entire rotating seat 12 to rotate to the right.
[0043] 6. When the fixed block 122 in the rotating seat 12 rotates to the position of the start limit switch 1241, the side of the fixed block 122 touches the start limit switch 1241, causing the start limit switch 1241 to close. At this time, the controller receives the signal that the start limit switch 1241 is closed, and the controller controls the driving motor 13 to stop working, and the driving motor 13 stops rotating, so that the bean grinder 2 stops at the starting position, and the sprinkler 3 is located above the coffee filter cup 100 at this time.
[0044] VII. At this time, the controller controls the water pump 8 to start working, pumps the water in the water tank 7, inputs the water through the first pipeline 65 into the heater 9 for heating, the water heated by the heater 9 is input through the third pipeline 67 to the water inlet of the sprinkler 3, and the sprinkler 3 sprinkles the water reaching the set temperature into the coffee filter cup 100, onto the coffee powder in the coffee filter cup 100, and the water sprinkled on the coffee powder then flows into the coffee cup 101. Thus, the entire working process of the coffee machine from grinding coffee beans to brewing coffee is completed.
