For those skilled in the art, all electrical components in this invention are connected to their matching power sources via wires, and appropriate controllers should be selected based on actual conditions to meet control requirements. The specific connection and control sequence should follow the working principles described below, completing electrical connections in the order of operation of each electrical component. The detailed connection methods are well-known technologies in the field. The following mainly describes the working principles and processes without further elaboration on electrical control.

In this embodiment: The assembly of this fan is made more convenient by using clamping blocks 6. When assembling the connecting plate 7 to the shroud 2, the connecting plate 7 is pressed toward the center of the shroud 2. The trapezoidal inclined surface of the elastic clamping block 6 is squeezed outward by the side edge of the connecting plate 7 until it falls into the opening on the side edge of the connecting plate 7, completing the combination of the connecting plate 7 and the shroud 2. When combining the front handheld shell 3 and the rear handheld shell 9, the assembly is also made faster by the elastic clamping blocks 6. When using this fan, pressing the control switch 11 once activates the power motor 4 through the control board 10. The power motor 4 starts and drives the fan blades 5 to rotate inside the shroud 2. The protective outer shell 1 at the back of the shroud 2 prevents the fan 5 from being exposed and causing scratches to the user. When in use, the digital display module 8 on the connecting plate 7 at the center of the shroud 2 shows the battery level of the battery 12, allowing users to intuitively know whether charging is needed. When using at night, pressing the control switch 11 twice consecutively activates the lighting device 13 through the control board 10. The light emitted by the lamp bead board 132 passes through the lampshade 133 to illuminate the outside, allowing users to safely use the fan at night without holding an additional lighting tool. To turn off the lighting, press the control switch 11 again twice in succession to turn off the lighting device 13. The electrical components inside the fan are powered by the battery 12. When the battery 12 is low on power, it can be charged through the USB interface 14 to ensure the normal use of the invention. The handle 15 on the rear handheld shell 9 makes it convenient for users to carry this invention.
