Abstract: The present disclosure discloses a high-speed neck fan, including a hanging piece and a fan body connected to an end portion of the hanging piece; the fan body includes a shell; an air duct and a coordination base are formed on the shell; the coordination base is connected to one side of a periphery of the air duct; the air duct and the coordination base are in a stacked state on a radial cross section of the air duct; one end of the air duct is an air inlet, and the other end is an air outlet. According to the present disclosure, when a user wears the high-speed neck fan, the high-speed neck fan is stable and will hardly move or fall off. Furthermore, the air speed and the air supply distance are greatly improved. The user experience is effectively enhanced.

Abstract: The present disclosure discloses a silent high-speed fan, including a shell; an air duct is formed on the shell; an air inlet and an air outlet are respectively provided at two ends of the air duct; a boosting mechanism is arranged in the air duct; a rectification mechanism is arranged at the air outlet; the rectification mechanism includes a necking hood that covers the air outlet and a rectification blade group composed of a plurality of rectification blades arranged coaxially on an inner side of the necking hood in an annular array. The present disclosure controls the details in an air flow stroke, so that the turbulence is eliminated step by step, and the turbulence is eliminated at the source, to achieve an effect of silently blowing air at a high speed.
