[0025] Refer to Figures 1 to 4 , a gas-electric dual-control structure of a coffee machine, including: a valve seat 2, a steam interface 21 is provided on the valve seat 2, a valve core 3 is movably installed on the valve seat 2, the valve core 3 is used to seal the steam interface 21, a microswitch 4 is fixedly installed on the valve seat 2, a cam 5 is provided on the valve core 3, and the cam 5 corresponds to the contact lever of the microswitch 4. When in use, the valve core 3 is moved, the opening and closing of the steam interface 21 are controlled by the valve core 3. At the same time, during the movement of the valve core 3, the cam 5 is带动 to move, and the cam 5 touches the contact lever of the microswitch 4, thereby controlling the opening or closing of the microswitch 4, and can联动 control the on-off of the circuit and the opening and closing of the steam valve, with simple operation.

[0026] As a preferred embodiment, a guiding hole 22 is opened on the valve seat 2, a guiding rod 31 is provided on the valve core 3, the guiding rod 31 extends into the guiding hole 22. When the valve core 3 rotates, the guiding rod 31 moves in the guiding hole 22, which can带动 the valve core 3 to expand and contract on the valve seat 2. When the valve core 3 extends outwards, the steam interface 21 is opened; on the contrary, when the valve core 3 contracts inwards, the steam interface 21 is closed.

[0027] In a preferred embodiment, the guide hole 22 includes a closed section 221 and an open section 222. When the valve core 3 rotates, the guide rod 31 moves from the closed section 221 to the open section 222, and the valve core 3 moves from an inward contraction state to an outward extension state.

[0028] In a preferred embodiment, a recess 223 is provided in the middle of the guide hole 22, and the recess 223 is connected to the opening section 222 by an inclined surface. In use, when the guide rod 31 is in the closed section 221, the valve core 3 is always in the closed state of the steam interface 21. When the guide rod 31 enters the recess 223, it can stop and generate a tactile sensation when rotated. When the guide rod 31 passes the recess 223 and enters the opening section 222, the valve core 3 extends outward, so that the steam interface 21 is in the open state and steam can be discharged.

[0029] In a preferred embodiment, the cam 5 includes a guide surface 51 located at one end of the cam 5. A notch 52 is provided at the bottom of the cam 5. When the contact rod of the micro switch 4 corresponds to the notch 52, the guide rod 31 is located within the recess 223. During use, when the valve core 3 rotates counterclockwise until the guide rod 31 is in the closed section 221, the guide surface 51 on the cam 5 contacts and presses the contact rod of the micro switch 4, causing the micro switch 4 to open. At this time, the circuit is energized, and the steam valve is closed. When the guide rod 31 moves to the recess 223, the contact rod of the micro switch 4 is located at the notch 52 and springs up, closing the micro switch 4. At this time, the circuit is open, and the steam valve is closed. When the guide rod 31 passes the recess 223 and enters the open section 222, the cam 5 presses the contact rod of the micro switch 4 again, opening the micro switch 4 and the steam valve is open. This allows the steam valve and the micro switch in the control circuit to be linked, forming different opening and closing combinations. The operation is simple and prevents misoperation.

[0030] In a preferred embodiment, the system also includes a housing 1, a valve seat 2 fixedly mounted on the housing 1, and a steam passage 11 provided inside the housing 1, which is connected to a steam interface 21.
