Abstract

The invention relates to a fan head assembly and an electric fan. The fan head assembly comprises a connector, a main motor and a housing, a supporting cylinder used for supporting the main motor is arranged on the connector, a shaft sleeve is inserted into the supporting cylinder, a supporting shaft of the main motor is inserted into the shaft sleeve, the relative positions of the supporting shaft and the shaft sleeve are fixed in the axial direction of the shaft sleeve, the shaft sleeve is provided with a limiting piece, the limiting piece is matched with the supporting cylinder in a concave-convex mode and used for limiting the shaft sleeve to move in the axial direction of the supporting cylinder relative to the supporting cylinder, the housing is connected with the main motor, and the housing at least partially corresponds to the concave-convex matching part of the limiting piece and the supporting cylinder and is used for preventing the limiting piece from being separated from the supporting cylinder, so that the supporting shaft can be stably and reliably supported on the connector.

Description

technical field [0001] The invention relates to the technical field of fan components, in particular to a fan head assembly and an electric fan. Background technique [0002] The fan blades of the electric fan are assembled on the main shaft of the main motor, the main motor is supported on the connector, and the main motor can rotate relative to the connector, so that the fan blades swing relative to the connector, so that the direction of the fan's air outlet changes . The main motor is generally supported on the connecting head through a support shaft, and the rotation axis of the main motor when it rotates is the axis of the support shaft. If the supporting shaft cannot be stably supported on the connecting head, the shaking effect of the electric fan will be poor. Based on this, how to ensure the stable and reliable support of the supporting shaft on the main motor on the connecting head is particularly important. Contents of the invention [0003] Aiming at the pr...
