摘要: A fan, comprising blades (102), an upper hub (111), and a lower hub (112). Each blade (102) comprises a connecting part (211). The connecting part (211) is clamped between a lower surface of the upper hub (111) and an upper surface of the lower hub (112). The lower surface of the upper hub (111) is provided with an upper hub connecting area, and the upper surface of the lower hub (112) is provided with a lower hub connecting area. An upper surface and a lower surface of the connecting part (211) are separately provided with a junction surface extending from the connecting part (211). The lower surface of the upper hub (111) and the upper surface of the lower hub (112) are separately provided with a matching surface matching the junction surface. The junction surface and the matching surface are arranged in the radial direction and/or circumferential direction of the upper hub (111) and the lower hub (112), and are configured to match with each other to impede the movement of at least two blades (102) in the circumferential direction and/or radial direction with respect to the upper hub (111) and the lower hub (112). The fan structure can prevent the movement of the blades (102) with respect to the upper hub (111) and the lower hub (112). The connecting part (211) and the fan body (201) are not easy to break and can be easily assembled, such that better stability can be ensured while the cost is low.
