The wires used to control the atomizer 1 and power the atomizer 1 do not need to run from the fan head to the support 5, making the design, assembly, disassembly and cleaning of the fan more convenient.

[0012] In some embodiments, the fan head includes an air outlet mesh 3, the air outlet side of the air outlet mesh 3 is provided with a control panel 2 and an atomizer 1, the main control board 22 is located between the control panel 2 and the air outlet mesh 3, and the air inlet side of the air outlet mesh 3 is provided with a motor for driving the impeller 6, and the motor is electrically connected to the main control board 22.

[0013] As described above, the user can control the fan via the control panel 2. The control panel 2 can be a panel with physical control buttons or a touch screen. In other embodiments, the control panel 2 can also be replaced with a decorative panel without control buttons.

[0014] In some embodiments, the wind turbine 6 is a diagonal flow wind turbine.

[0015] As can be seen from the above description, the impeller 6 is an oblique flow impeller, which can make the area near the outer edge of the fan head air outlet side air outlet, and there is enough space in the center of the fan head air outlet side to arrange the control panel 2 and the atomizer 1.

[0016] In some embodiments, please refer to Figure 2 and Figure 3 The air outlet 3, motor and impeller 6 are arranged in sequence from front to back; the impeller 6 has a cover plate 61 and multiple blades 62, the front end of the blades 62 is connected to the rear side of the cover plate 61, the rear end of the blades 62 is a free end, and the motor is connected to the cover plate 61.

[0017] As described above, the rear end of the impeller 6 is a free end, which allows the demolding method of the impeller 6 to change from the rotational demolding of a conventional oblique-flow impeller to oblique straight demolding, thus helping to reduce the difficulty and cost of mold manufacturing for the impeller 6. In other embodiments, the impeller 6 can also be a conventional oblique-flow impeller, with cover plates connected to both the front and rear ends of the blades 62.

[0018] In some embodiments, please refer to Figure 3 and Figure 4 The control panel 2 is provided with a female contact 21, which is electrically connected to the main control board 22; the atomizer 1 includes a water tank 10 and an atomizing plate 12 disposed in the water tank 10, and the water tank 10 is provided with a female contact 121, which is electrically connected to the atomizing plate 12; the water tank 10 is detachably connected to the air outlet 3 and / or the control panel 2, and the female contact 121 is detachably connected to the female contact 21.

[0019] As described above, the user can detach the atomizer 1 from the air outlet 3. When the atomizer 1 is detached, the electrical connection between the atomizer 1 and the main control board 22 is broken by the separation of the female contact 121 and the female contact 21. The female contact 121 or the female contact 21 can be retractable to ensure effective contact between them. The use of the female contact 121 and the female contact 21 to achieve the electrical connection between the atomizer 1 and the main control board 22 facilitates the user's removal of the atomizer 1. In other embodiments, the atomizer 1 and the main control board 22 can also be connected by wires.

[0020] In some embodiments, the water tank 10 is detachably connected to the air outlet 3 and / or the control panel 2 via snap-fit.
