[0025] Reference Figures 2-4 A dual-control structure for a coffee machine, comprising a main body 1, a valve stem 2, and a micro switch 3. The valve stem 2 corresponds to one side of the main body 1, and the micro switch 3 includes a contact rod 31, which corresponds to the bottom of the main body 1. In use, it is combined with... Figure 1 and Figure 4 The second inclined surface 13 at the bottom of the main body 1 presses the contact rod 31 of the micro switch 3, and the plane 12 presses the valve rod 2. At this time, the micro switch 3 is turned on, the coffee machine is powered on, the water valve is opened, and water can flow to the extraction device to realize coffee extraction, corresponding to the coffee machine's extraction function. When the main body 1 is rotated, the valve rod 2 moves relative to the main body 1 toward the first inclined surface 11. The main body 1 no longer presses the valve rod 2, the valve rod 2 springs up, and the water valve is closed. At this time, the main body 1 continues to press the contact rod 31 of the micro switch 3, and the micro switch 3 is turned on. At this time, the water circuit is closed and the circuit is turned on. When the main body 1 is rotated again, the valve rod 2 continues to move along the first inclined surface 11, the water valve is closed, and at the same time, the contact rod 31 of the micro switch 3 springs up corresponding to the notch 14. At this time, the micro switch 3 is turned off, and the circuit is de-energized.
