Among them, the same or similar reference numerals always indicate the same or similar elements or elements having the same or similar functions. Hereinafter, the embodiment described with reference to the drawings is an example, and is intended to interpret the utility model, and does not restrict the utility model.

  Hereinafter, an oscillating fan of a rotary electric fan according to an embodiment of the present utility model will be described with reference to FIGS.

  As shown in FIGS. 1 to 4, the rotary electric fan described in this utility model includes a pedestal 1 and a cover 2 provided on the pedestal 1, and a mounting chamber for fixing and radiating heat in the cover 2. 5, a movable support member 9 is movably connected to the mounting chamber 5, a lower end of the movable support member 9 is fixed to the pedestal 1, and an arc-shaped rack 8 facing the cover 2 in the cover 2. The stepping motor 6 is fixed to the movable support member 9, the driving gear 601 is provided on the stepping motor 6, and the driving gear 601 is meshed with the arc-shaped rack 8. Here, by omitting the bracket device from the pedestal 1, the overall structure is simplified and the manufacturing difficulty is further reduced. Furthermore, by providing the arc-shaped rack 8 and the drive gear 601 on the cover 2, the overall structure is simplified and the vertical rotation can be realized, thereby further improving the overall fashion and beauty. Furthermore, the air can be blown in the form of up and down swinging in the range of 90 degrees, further expanding the blowing range.

  When the vertical rotation of the cover 2 is requested, the operation of the step motor 6 is started, and the arc rack 8 is moved forward or backward via the drive gear 601 so as to achieve the vertical rotation function. ing.
