Abstract

The invention relates to a multi-slot type variable-speed fan. The fan includes a fixed end, a power supply line, a connection rod, a stator end, a drive motor, a rotating hood and fan blades; the fixed end is connected with the stator end through the connection rod, the stator end and the rotating hood are connected with the drive motor respectively, the power supply line is connected with drivemotor, the fixing ends of the fan blades are provided with plugs, the rotating hood is provided with inserted grooves, the fan blades are fixedly installed by inserting the plugs into the inserted grooves in the rotating hood. The rotating hood is provided with twelve inserted grooves, the inserted grooves are distributed in a circular-ring shape, and the included angles between adjacent insertedgrooves are equal. Several inserted grooves are formed in the rotating hood, and when the fan is in use, the number of the fan blades in the inserted grooves can be adjusted so that the volume of airblown by the fan can be changed.

Description

technical field [0001] The invention relates to the field of electrical appliances, in particular to a multi-slot variable-speed fan. Background technique [0002] A kind of miniature ceiling fan is arranged on the market at present, because this ceiling fan structure is simple, and cost is lower, so have good market. But because this ceiling fan is driven by a permanent magnet synchronous AC motor, although there is a better energy-saving effect, the rotating speed is relatively single, so the rotating speed cannot be adjusted, and the wind speed cannot be better changed during use. Therefore, in order to solve the above problems, the prior art needs to be improved. Contents of the invention [0003] The purpose of the present invention is to provide a multi-slot variable speed fan, which solves the problem that the wind speed cannot be changed without adjusting the speed. [0004] In order to solve the above technical problems, the embodiment of the present invention p...
