[0030] Specifically, when in use, the rotating shaft of the fan motor 23 rotates, driving the fan blades 22 to rotate, and the rotation of the fan blades 22 drives the air flow to form blowing. The direction of the fan blades 22 can be adjusted by rotating the motor housing 21 up and down to adjust the blowing direction of the fan device 20, and such a rotating structure makes it possible for the motor housing 21 to not interfere with the support base 10 when rotating, and the motor housing 21 can rotate 360°, and the blowing direction of the fan device 20 can be adjusted 360°.

[0031] The utility model sets a rotatable motor housing 21 on the side of the support base 10, and the rotation axis of the motor housing 21 is parallel to the horizontal direction, so that the motor housing 21 can rotate up and down, and the motor is installed on the motor housing 21, and the extension direction of the motor shaft is perpendicular to the rotation direction of the motor housing 21, and then the fan blades 22 are installed on the motor shaft. In this way, the up and down angles of the fan blades 22 can be adjusted by rotating the motor housing 21. The motor housing 21 is set on the side of the support base 10 so that the motor housing 21 will not interfere with the support base 10 when rotating up and down. The motor housing 21 can rotate 360°, and the blowing direction of the fan device 20 can be adjusted 360°, which is more convenient for users to use.

[0032] In some embodiments, the floor fan further includes a first drive motor, a first bearing is provided between the motor housing 21 and the support base 10, the inner ring and the outer ring of the first bearing are respectively connected to the motor housing 21 and the support base 10, the rotation axis of the first bearing is parallel to the horizontal direction, the first drive motor is provided in the support base 10, and is electrically connected to the electric control device, the rotating shaft of the first drive motor is connected to the motor housing 21, and is used to drive the motor housing 21 to rotate relative to the support base 10. Specifically, when in use, the fan motor 23 drives the fan blades 22 to rotate to drive the air flow to form blowing, and at the same time, the first drive motor runs, driving the motor housing 21 to rotate relative to the support base 10, so that the fan device 20 rotates up and down while blowing, and the fan device 20 can blow air to multiple positions, thereby increasing the blowing range of the fan device 20.

[0033] In some embodiments, the support base 10 includes a base 11 and a mounting frame 12, the mounting frame 12 is rotatably mounted on the base 11, the rotation axis of the mounting frame 12 is parallel to the up and down direction, and the motor housing 21 is disposed on the mounting frame 12. Specifically, when in use, the base 11 is fixed to the ground, and when the mounting frame 12 is rotated relative to the base 11, the fan device 20 located on the side of the mounting frame 12 rotates along with the mounting frame 12, so that the blowing direction of the fan device 20 can be adjusted 360° in the horizontal direction, and the user experience is better.

[0034] In some embodiments, the floor fan further includes a second drive motor, a second bearing is provided between the base 11 and the mounting frame 12, the inner ring and the outer ring of the second bearing are respectively connected to the base 11 and the mounting frame 12, the rotation axis of the second bearing is parallel to the up and down direction, the second drive motor is provided in the mounting frame 12, and is electrically connected to the electric control device, the rotating shaft of the second drive motor is transmission-connected with the base 11, and is used to drive the mounting frame 12 to rotate relative to the base 11.

[0035] In some embodiments, the motor housing 21 includes a first mesh cover 212 and a housing 211, the housing 211 is cylindrical and rotatably mounted on the support base 10, the first mesh cover 212 is arranged at the rear end of the housing 211, the first mesh cover 212 is provided with a mounting shell 213, the fan motor 23 is mounted on the mounting shell 213, the radial dimension of the housing 211 is greater than the radial dimension of the fan blades 22, and the fan blades 22 are located in the housing 211. Specifically, the cylindrical housing 211 is located outside the fan blades 22 to surround the fan blades 22, so that the wind blown by the fan blades 22 is more concentrated, and the user can feel a greater wind when using. And the first mesh cover 212 is located at the rear side of the housing 211, which can prevent objects from entering the housing 211 from the rear side of the housing 211 and hitting the high-speed rotating fan blades 22, and at the same time will not affect the airflow entering from the rear side of the housing 211.
