[0026] Working principle:

[0027] Start the electric actuator 201, and the transmission end of the electric actuator 201 drives the second valve core 301 and the rubber block 304 to move upward, and at the same time drives the spring 203 to contract upward. At this time, the water flows through the water inlet groove 303 opened by the first valve core 202 to the inside of the first valve core 202, and then flows through the water outlet groove 305 opened by the circular slide rail 302 to the water inlet groove 303 opened on the right side of the first valve core 202, and flows to the fan blade 208.
