Specifically, the stator 131 is stationary relative to the fan housing 11 means that: when the fan is operated, no relative movement is generated between the stator 131 and the fan housing 11. The relative rest of the rotor 132 with respect to the fan blades 12 means: when the fan is running, no relative movement is generated between the rotor 132 and the blades 12. The fan housing 11 and/or the stator 131 are connected to the swing mechanism 2 in the form of: in the first form, the fan housing 11 and the swing mechanism 2 are in direct connection, and the stator 131 and the swing mechanism 2 are not in direct connection; in the second form, the fan housing 11 and the swing mechanism 2 are not in direct connection, and the stator 131 and the swing mechanism 2 are in direct connection; in a third form, both the housing 11 and the stator 131 are in direct connection with the swing mechanism 2. Because the fan housing 11 and the stator 131 are in a relatively static relationship, all three forms can enable the swinging mechanism 2 to simultaneously drive the fan housing 11, the fan blades 12 and the first motor 13 to perform swinging motion together. The orbiting motion is a spatial stereoscopic motion, which is specifically a combined motion of rotation and oscillation. According to the fan head assembly 100 provided by the embodiment of the invention, the fan blades 12 can be normally driven by the first motor 13 to rotate and blow, and the fan cover 11, the first motor 13 and the fan blades 12 can be simultaneously driven by the rotary swing mechanism 2 to rotate and swing, so that the whole fan head main body 1 can realize the combination of two head swing modes under the driving of the same power mechanism, further the fan head main body 1 realizes the function of spatial three-dimensional head swing, the air supply area range of a fan is effectively enlarged, the rotary output of the wind direction is realized, and the wind sense output by the fan is softer and more natural.

Preferably, referring to fig. 1-3, the first motor 13 is mounted within the housing 11, the housing 11 is coupled to the swing mechanism 2, and the stator 131 is coupled to the housing 11. In this scheme, there is direct connection between the fan housing 11 and the swinging mechanism 2, there is no direct connection between the stator 131 and the swinging mechanism 2, and the stator 131 is connected to the fan housing 11, so that not only the design requirement of the stator 131 and the fan housing 11 for relative static is satisfied, but also the design requirement that the stator 131 and the fan housing 11 can swing together under the driving of the swinging mechanism 2 is satisfied.
Preferably, as shown with reference to fig. 1, 2 and 4, the stator 131 is connected to the fan housing 11 through a connection bracket 14, which facilitates the flexible design of the connection bracket 14 to meet the assembly requirements of different first motors 13 and the fan housing 11, thereby facilitating the simplification of the installation structure of the first motors 13 and the fan housing 11. Of course, alternatively, the stator 131 may be designed to be directly connected to the fan housing 11 without designing the connection bracket 14.
Preferably, referring to fig. 1, 2 and 4, the fan housing 11 includes a main housing 111, a front net 112 assembled to one end of the main housing 111, and a rear net 113 assembled to the other end of the main housing 111, the rear net 113 connecting the stator 131 and the swing mechanism 2.

Preferably, the cam 231 is an eccentric wheel, and the connecting rod 233 and the fan head main body 1 can perform a stereoscopic conical motion relative to the output shaft 221 of the second motor 22 under the driving of the cam 231, so that the fan head main body 1 can achieve a stereoscopic shaking effect. Specifically, in the fan head assembly 100 provided in this embodiment, under the driving of the second motor 22, the swing transmission pair 23 can make a stereoscopic conical movement around the output shaft 221 of the second motor 22, and since the fan head main body 1 is connected with the swing transmission pair 23, the fan head main body 1 will make a stereoscopic conical movement along with the swing transmission pair 23, so that the fan head main body 1 makes an outward rotary conical movement relative to the fixed base 211, and through this simple 3D movement, the blowing range of the whole fan can be enlarged, and the effect that the small-size fan can blow out the large-size fan can be achieved. Of course, alternatively, the cam 231 may take other shapes, for example, the cam 231 may be configured as an oval wheel or other irregular wheel, and in a specific application, the cam 231 may be configured such that the fan head body 1 may achieve a three-dimensional panning effect with different trajectories.
Specifically, referring to fig. 1, 2 and 6, the central axis 2330 of the connecting rod 233 has an angle a with the central axis 2210 of the output shaft 221, and the angle a preferably satisfies the relationship: a is more than 0 DEG and less than or equal to 30 deg. The included angle A is the swing angle of the power output by the swing mechanism 2. The larger the angle a is designed, the larger the swing range of the fan head main body 1 is, but the larger the cam 231 and the link 233 are. Here, the included angle a is designed to be 0 ° -30 °, so that the requirement of the swing range of the fan head main body 1 in most occasions can be met, and the cam 231 and the connecting rod 233 cannot be oversized, thereby facilitating the miniaturization design of the product, and simultaneously enabling the product to be easier to design and manufacture.
