Novel high-power fan

The invention discloses a novel high-power fan, and relates to the technical field of fan manufacturing, the novel high-power fan comprises a cylindrical fan main body, a protection plate is arranged on the outer wall of the fan main body, fan blades are arranged in the fan main body, and a manual false triggering mechanism is arranged on the outer wall of the front side of the fan main body; supporting mechanisms are arranged on the two sides of the protection plate, a first tooth groove rod, a partition plate and fan blades are matched with one another, the mechanism is manually triggered by mistake, the fan body can be prevented from being started due to accidental operation or misoperation, when mistaken touch occurs, the mechanism can automatically trigger the partition plate to move, open and close to shield an air opening, and the safety of the fan is improved. And meanwhile, the air opening is shielded through opening and closing, adverse effects generated during operation of the draught fan body can
