The fan body 100 is adapted to extend from the edge of the mobile phone and deliver air to the user. The fan body 100 comprises a housing and a blower 103. The housing comprises an inner housing 102 and an outer housing 101 coaxially arranged. An air inlet 104 and an air outlet 105 are formed at two axial ends of the inner housing 102. The blower 103 is built into the inner housing 102 and drives air from the air inlet 104 to the air outlet 105. The inner housing 102 and the outer housing 101 enclose a first cavity 106 and a second cavity 107 disposed around the air outlet 105. The first cavity 106 is adapted to accommodate a control circuit board 110 and a battery 111, while the second cavity 107 is adapted to accommodate the fill light assembly. Second cavity 107 includes a circular, translucent cover plate 113, and the fill light assembly includes an LED array 112 shaped to match the translucent cover plate 113. The annular LED array 112 provides uniform, soft lighting, resulting in a more natural, brighter skin tone when taking selfies.

[0046] In this embodiment, the LED lamp bead group 112 includes a plurality of unit lamp beads, which are divided into red unit lamp beads, green unit lamp beads and blue lamp beads. The control circuit board 110 includes a PWM module. The PWM module is suitable for regulating the luminous ratio of each color lamp bead or each color unit lamp bead, thereby regulating the color temperature of the LED lamp bead group 112. It is understandable that red lamp beads, green lamp beads and blue lamp beads can also be set in each unit lamp bead to achieve the above-mentioned adjustment function. In some other embodiments, the control circuit board 110 also includes a communication module. The communication module is suitable for receiving control signals sent by a mobile phone to realize intelligent control of the fan and fill light by the mobile phone, which is simple to operate and provides timely feedback.
