The front cover and the rear cover are connected to form a cover, and an opening is provided on the surface of the rear cover. An electric fan that is adjustable at a large angle with one end of the support member connected and the other end of the support member placed in the opening, the inner pedestal is fixed in the cover, and the drive member is on the side of the inner pedestal Provided, the other end of the drive member and the support member is movably connected, a motor is fixed in the inner pedestal, a pressing member is connected to the motor, and a stopper is fixed to the other end of the support member. Is connected to the connecting arm, the pressing member and the connecting arm are connected by a hinge, and the stopper is in contact with the surface of the connecting arm.

  Specifically, the rotating shaft of the motor and the pressing member are connected by a swing arm.

  Specifically, at least two positioning arc portions are provided on the surface of the connection arm, the positioning arc portions are connected to each other to form a positioning recess, and a stopper is placed in contact with the positioning recess.

  Specifically, a ball and a spring are provided in the stopper, one end of the spring is brought into contact with the surface of the ball, and the ball is placed in the positioning recess.

  Specifically, the pressing member has an arc shape.

  Specifically, the motor and the inner pedestal are connected by screws.

  Specifically, the opening of the inner pedestal faces the inner surface of the rear cover, and a vent hole is provided on the surface of the rear cover.

  As a beneficial effect of the present invention, when the swing arm is driven by a motor, the swing arm pushes the connection arm so that the inner base swings within a range of 270 angles. In addition, the stopper is fixed to the support member so that the positioning function is exhibited, and the angle of the cover can be artificially adjusted even when the operation of the motor is stopped. Both artificial adjustments can be realized, and adjustments can be made at a large angle, meeting the needs of different customers and realizing an indoor temperature reduction effect.
