Abstract: Provided in embodiments of the present application are a head mechanism and a fan apparatus. The head mechanism includes: a casing, where a primary air inlet and an air outlet are provided on a circumferential side wall of the casing, and an auxiliary air inlet is provided on an axial wall surface of the casing; and a centrifugal volute arranged in the casing, where a centrifugal fan is arranged in the centrifugal volute, and an air duct outlet corresponding to the air outlet and an air duct inlet corresponding to the auxiliary air inlet are provided on the centrifugal volute; and air flowing from the primary air inlet and the auxiliary air inlet flows into the centrifugal volute through the air duct inlet. According to the embodiment of the present application, since the primary air inlet located on the circumferential side wall is provided.

Abstract: Provided in embodiments of the present disclosure are a fan blade assembly and a fan apparatus. The fan blade assembly includes: a primary fan blade, where multiple first blades circumferentially provided are arranged on the primary fan blade; an auxiliary fan blade arranged coaxial and adjacent to the primary fan blade, where multiple second blades circumferentially provided are arranged on the auxiliary fan blade, an air inlet direction of the auxiliary fan blade is an axial direction, an air outlet direction of the auxiliary fan blade is a radial direction, and the first blades and the second blades have different torsion directions; and an motor arranged on one side of the auxiliary fan blade away from the primary fan blade, where the primary fan blade has a maximum outer diameter greater than an outer diameter of the auxiliary fan blade. According to the embodiment of the present disclosure.
