Problems solved by technology
[0002] At present, the speed regulation function of the electric fan is to change the speed by connecting the lead wires with different winding numbers of the motor through the gear switch, and to adjust the speed through the electronic control circuit board, but these speed changes are all through the change of electricity. , the maximum speed is not greater than the speed of the motor, and the speed of the motor is limited by the structure of the motor, so there are no more speed choices, and there is no free gear or idle function

The invention relates to the technical field of electric fans, in particular to a planetary gear speed-variable electric fan. The planetary gear speed-variable electric fan comprises a base, a vertical column, a motor, fan blades, a back mesh cover and a front mesh cover. A rotating shaft of the motor is connected to a transmission which is mounted between the fan blades and the motor. The transmission comprises a planetary gear transmission seat connected with the motor, the rotating shaft of the motor is in transmission connection with a planetary gear, the fan blades are mounted on a shaftrod of a sun gear, and one end, opposite to the shaft rod, of the sun gear is inserted to one end, away from the planetary gear transmission seat, of the planetary gear. The sun gear is meshed with one end of a gear ring through the planetary gear, a gear shift rod and a transmission cover are mounted at the other end of the gear ring from left to right, and the gear shift rod axially controls thegear ring position in a connected, free or fixed state.
Description
technical field [0001] The invention relates to the technical field of electric fans, in particular to a planetary gear variable speed electric fan. Background technique [0002] At present, the speed regulation function of the electric fan is to change the speed by connecting the lead wires with different winding numbers of the motor through the gear switch, and to adjust the speed through the electronic control circuit board, but these speed changes are all through the change of electricity. , the maximum speed is not greater than the speed of the motor, and the speed of the motor is limited by the structure of the motor, so there are no more speed options, and there is no free gear or idle function. Contents of the invention [0003] The object of the present invention is to provide a planetary gear variable-speed electric fan to solve the problems raised in the above-mentioned background technology. [0004] In order to achieve the above object, the present invention ...
