[0013] In order to deepen the understanding of the present invention, the present invention will be further described in detail below in conjunction with embodiments and drawings. The embodiments are only used to explain the present invention and do not constitute a limitation on the protection scope of the present invention.

[0014] See attached Figure 1-2 The present application provides a desktop fan that can rotate horizontally to supply air, which includes a base 1, a fan bracket and a fan body 2. The fan body is installed on the fan bracket, and the fan bracket has a connecting seat 3 rotatably connected to the base 1. The middle part of the base has a positioning shaft 4 extending upward and extending into the connecting seat. The positioning shaft can rotate relative to the connecting seat. The positioning shaft can ensure the coaxiality of the connecting seat during rotation to avoid offset or shaking. The connecting seat 3 is provided with a plurality of circumferentially evenly distributed balls 5, and the base is provided with an annular slideway for matching the rolling of the balls. The positioning shaft is provided with a first gear 6, and the connecting seat 3 is provided with a second gear 7 and a driving motor 8 that drives the second gear to rotate. The first gear is meshed with the second gear. When the driving motor drives the second gear to rotate, since the first gear and the second gear are in a meshing state, and the second gear is in a fixed state, the first gear rotates around the second gear, thereby driving the entire connecting seat to rotate.

[0015] The connecting seat 3 is provided with a ball bracket 9, and the ball 5 is assembled on the ball bracket. The ball bracket is detachably connected to the connecting seat 3. When the ball is worn or rolls unsmoothly, the ball bracket can be removed for replacement as a whole.

[0016] The middle of the connecting seat 3 is provided with an axial hole for the positioning shaft to pass through. The positioning shaft is provided with a shaft sleeve 10 or a bearing, and the shaft sleeve is connected to the axial hole. The shaft sleeve can ensure the tightness of the connection between the connecting seat and the base without affecting the smooth rotation of the connecting seat.

[0017] The drive motor 8 is invertedly installed inside the connecting seat. The connecting seat is provided with a hole for the motor shaft of the drive motor to pass through. The motor shaft is connected to the second gear 7. The drive motor is fixed to the connecting seat by screws.

[0018] A control panel is provided on the surface of the connecting seat 3, which is used to control the working status of the fan body 2 and the driving motor 8. The user can start or shut down the operation of the fan body and adjust the wind speed through the control panel. The user can also control whether the driving motor rotates through the control panel to select whether the connecting seat rotates to supply air.

[0019] The fan bracket includes a left-right symmetrical and vertically arranged connecting arm 11, and the left and right sides of the fan body 2 are rotatably connected to the inner side of the connecting wall respectively. The user can adjust the upper and lower angles of the air outlet by rotating the fan body up and down.

[0020] The above are only preferred embodiments of the present invention, and the protection scope of the present invention is not limited to the above embodiments. Any equivalent modifications or changes made by ordinary technicians in this field based on the contents disclosed in the present invention should be included in the protection scope recorded in the claims.
