[0056] The air inlet grille 317 and the air outlet grille 319 can be disassembled and assembled, which can make the oscillating fan 100 more convenient to clean the dust accumulated in the air outlet cavity 313, better protect the cleanliness of the air outlet of the oscillating fan 100, avoid the influence of the accumulated dust on the air volume of the air outlet airflow, and further improve the practicability and reliability of the oscillating fan 100.

[0057] Referring to Figure 7In an embodiment of the present application, the fan blade 35 comprises an inner hub 351, an outer hub 353, a first blade 355 and a second blade 357, the inner hub 351 is connected to the fan body 33; the outer hub 353 is coaxially arranged with the inner hub 351 and is sleeved on the outer periphery of the inner hub 351, and an air inlet flow channel is formed between the outer hub 353 and the inner hub 351; the first blade 355 is connected to the outer periphery of the outer hub 353; the second blade 357 is arranged in the air inlet flow channel and connects the outer hub 353 and the inner hub 351.

[0058] In the embodiment, by forming the air inlet flow channel between the coaxially arranged outer hub 353 and the inner hub 351, and arranging a plurality of first blades 355 around the outer periphery of the outer hub 353, and a plurality of second blades 357 are arranged around the inner wall of the outer hub 353 and the outer wall of the inner hub 351 to connect the outer hub 353 and the inner hub 351, the fan blade 35 structure in the combined air outlet form can better improve the turbulence blowing effect of the fan assembly 30. Among them, the first blade 355 can adopt an axial flow blade or an inclined flow blade, and the second blade 357 can adopt a centrifugal blade. Since the number of centrifugal blades is not affected by the size of the hub and the ratio of the hub, the design requirement of small hub and multiple blades is met, so that the inner hub 351 can be designed in a smaller size, and compared with the fan blade 35 structure only provided with axial flow blades, the second blade 357 in the form of centrifugal blades can increase the number of second blades 357, which is beneficial to better increase the air inlet volume of the fan blade 35. At this time, by forming the air inlet flow channel between the outer hub 353 and the inner hub 351, the airflow disturbed by the outer hub 353 to the second blade 357 can be guided under the centrifugal action, so that the airflow generated by the second blade 357 is blown along the axial direction of the driving shaft of the fan body 33. At this time, the rotation of the first blade 355 can generate axial or inclined airflow, and then the airflow generated by the first blade 355 and the airflow generated by the second blade 357 can be combined and discharged, so that the fan blade 35 can generate greater air volume when rotating, further improving the blowing air volume of the head-shaking fan 100, which is beneficial to better reduce the operating power of the fan body 33, and improves the practicability and reliability of the head-shaking fan 100.

[0059] The second blade 357 in the form of a centrifugal blade can generate airflow with a larger wind pressure, and the airflow generated by the first blade 355 and the airflow generated by the second blade 357 are mixed, so that the airflow generated by the fan blade 35 has a higher air pressure and flow rate, and the blowing effect of the oscillating fan 100 is better improved. Since the linear speed of the inside of the axial flow blade is smaller than that of the outside, the airflow generated by the axial flow blade has the characteristics of small inside speed and large outside speed, so when the first blade 355 is an axial flow blade, the second blade 357 is arranged between the inner hub 351 and the outer hub 353, and the airflow generated by the second blade 357 can compensate for the insufficient linear speed of the inside of the first blade 355, so that the fan blade 35 can blow out more uniform airflow, better realize the large air volume blowing effect of the oscillating fan 100, and further improve the practicability and reliability of the oscillating fan 100.

[0060] In addition, the outer hub 353 can include a first wind gathering ring and a second wind gathering ring, the first blade 355 is connected to the outer periphery of the first wind gathering ring, the second wind gathering ring is arranged in the first wind gathering ring, one end of the second wind gathering ring is connected to the inner wall of the first wind gathering ring, and the second blade 357 is connected to the inner hub 351 and the second wind gathering ring. The outer periphery of the second wind gathering ring is arranged at an angle with the inner wall of the first wind gathering ring, and the width of the second wind gathering ring is configured to gradually increase in the direction from the air inlet 3131 to the air outlet 3133. By arranging the inclined second wind gathering ring in the first wind gathering ring, the second wind gathering ring can be designed in a gradually expanding horn shape along the air inlet direction, and the inner hub 351 and the second wind gathering ring are connected by the second blade 357. After the air enters the air inlet flow channel, it is disturbed by the second blade 357, and due to the disturbance of the second blade 357 in the form of a centrifugal blade, the airflow can be subjected to a certain centrifugal force between the second wind gathering ring and the inner hub 351, so that the airflow can flow along the inner wall of the second wind gathering ring. At this time, by arranging the second wind gathering ring to be inclined, the airflow generated by the second blade 357 can be blown out obliquely along the inner wall of the second wind gathering ring, which is beneficial to guiding the airflow to a certain extent, so that the airflow can be more easily discharged from between the inner hub 351 and the second wind gathering ring, reducing turbulence or noise generated by the airflow. In addition, the airflow disturbed by the second blade 357 can more quickly meet the airflow disturbed by the first blade 355 under the action of the inclined arrangement of the second wind gathering ring, realizing the rapid mixing of the two airflows, and further improving the flow rate of the mixed airflow generated by the fan blade 35, and further improving the high-speed blowing effect of the oscillating fan 100.
