Portable fan

A portable fan, comprising:

• a shell assembly provided with a cable outlet;
• a fan arranged on the shell assembly, the shell assembly being provided with an air outlet for air outgoing of the fan;
• a power module arranged on the shell assembly and configured to supply power to the fan;
• and
• a retractable cable module arranged on the shell assembly and comprising a cable body and a butt joint connected to one end of the cable body, wherein the butt joint is configured to butt to an external electronic device;
• a width of the butt joint being not larger than that of the cable outlet, and a cross-sectional area of the butt joint is not greater than a cross-sectional area of the cable outlet, such that the butt joint is capable of passing from an interior of the shell assembly to an exterior of the shell assembly through the cable outlet in an assembly process;
• the cable body is capable of retracting into the cable outlet to be accommodated in the shell assembly, the cable body is also capable of being pulled out of the shell assembly to butt the butt joint to the external electronic device and supply power to the external electronic device through the power module;
• wherein the butt joint has a first position and a second position relative to the shell assembly, and in the first position, the cable body is accommodated in the shell assembly and the butt joint is at least partially accommodated in the cable outlet;
• in the second position, the cable body and the butt joint extend out of the shell assembly for butting to the external electronic device;
• wherein the portable fan comprises an ejecting assembly arranged on the shell assembly, and the ejecting assembly is configured to be triggered to eject the butt joint in the first position out of the shell assembly through the cable outlet;
• wherein the ejecting assembly comprises an elastic member arranged in the shell assembly and a slider connected to the elastic member, and in the process that the butt joint is switched from the second position to the first position, the slider is driven by the butt joint to move inside the shell assembly and locked in the first position, and the elastic member accumulates elastic potential energy;
• the slider is configured to be triggered to be unlocked from the shell assembly, and the elastic member drives the slider to drive the butt joint to be ejected out of the shell assembly.
