A circuit board 170 is located in the first chamber 111, the circuit board 170 also being connected to the bracket 115. The circuit board 170 is electrically connected to the main motor 131, the operation panel 120, and the lamp 150, respectively. The user can control the operation state of the fan through the operation panel 120, and the use is convenient. The circuit board 170 is located between the fan assembly 130 and the operation panel 120, and the length of the wires of the fan assembly and the operation panel 120 can be shortened. For the convenience of wiring, a wiring rack 119 is provided on the housing 110, and as shown in fig. 4, the wires for connecting the electrical components are received in the wiring rack 119.

In some embodiments, the operation panel 120 is a mirror surface, so that the fan can be used as a cosmetic mirror. The operation button 121 may be a touch button, and does not affect the image formation of the mirror. For convenience of use, in some embodiments, the air outlet 112 is located at the periphery of the operation panel 120, so as to realize a circumferential air outlet blowing mode, and achieve uniform blowing without affecting the use of the mirror surface. The air outlet 112 may surround the operation panel 120 in a whole circle, or may surround a part of the operation panel 120, and the specific arrangement form of the air outlet 112 is not limited in this application.

The fan 1000 may be placed directly on a flat surface, may be hooked to an object, or may be held by a hand. In view of the convenience of users who typically sit in front of a vanity while making up, in some embodiments, the fan 1000 further comprises a base 200. The entire host portion 100 is mounted on the base 200, and particularly, the housing 110 is connected to the base 200. The base 200 may rest on a table or floor surface such that the fan 1000 is closer to a table or floor fan.

The base 200 can be used as a mounting base besides facilitating the placement of the whole fan 1000, for example, in some embodiments, a power supply device 300 is disposed in the base 200, the power supply device 300 is used for supplying power to various electric components (e.g., the fan assembly 130 and the lamp 150) in the fan 1000, and for facilitating wiring, a wiring rack 119 is correspondingly disposed in the housing 110, as shown in fig. 4. The power supply device 300 may be at least one of a rechargeable battery pack, a dry battery, and a cord with a plug, and for convenience of use, the TYPE-C interface is used as the charging interface 310, and power can be supplied through a mobile phone adapter. Of course, in some embodiments, the power supply device 300 may also be disposed in the first chamber 111, and the application is not limited thereto.

In some embodiments, the fan 1000 has pitch adjustment functionality. And in particular the pitch angle between the main body part 100 and the base 200, can be adjusted. Referring to fig. 3, a sliding seat 210 is disposed in the base 200, a sliding rail 160 capable of slidably engaging with the sliding seat 210 is disposed in the housing 110, and the housing 110 is mounted on the base 200 through the sliding seat 210, so that the posture of the main body portion 100 relative to the base 200 is adjustable.
