When the fan head 2 is turned over on the fan head support 12, the left end of the second pipe 433 and the pipe connector 42 rotate relative to each other. At the same time, under the action of the sealing rubber 44, the second pipe 433 and the pipe connector 42 will not leak water mist. Alternatively, the pipe connector 42 may not be inserted into the plug hole 211, and the pipe connector 42 may be set Figure 4On the left side of the middle plug hole 211, a second pipe 433 is used to pass through the plug hole 211 and connect to the pipe connector 42. The other end of the pipe connector 42 is bent to facilitate the transmission of water mist. The specific bending direction and angle can be set according to actual needs. Alternatively, the pipe connector 42 can be omitted, and the humidification pipe 43 is rotatably connected to the plug hole 211.
