Abstract

The invention provides a fan. The fan comprises a head and a driving device connected with the head, wherein the driving device comprises a device body and a driving shaft, the head comprises a fan housing, a plumb line of the gravity center of the fan housing is coaxial with the driving shaft, so that the end of the driving shaft is no longer subject to the force perpendicular to the driving shaft, under the situation of the rotation of the driving shaft, resonance is not easy to generate, the vibration noise of the fan during running can be effectively reduced, and the use experience of users is improved.

Description

technical field [0001] The invention relates to the technical field of air conditioning devices, in particular to a fan. Background technique [0002] The fan is an essential small household appliance in every household. Because it is widely used, the manufacturing technology of the fan is relatively mature. The motor shaft of the motor of the existing fan is arranged horizontally, the head of the fan is arranged vertically, the weight of the head of the fan acts on the end of the motor shaft, and the force direction of the whole fan head is perpendicular to the axial direction of the motor shaft If the force on the head of the entire fan is unbalanced, it is easy to cause resonance when the motor shaft drives the fan blades to rotate, resulting in relatively large noise. Moreover, if the fan continuously increases its rotational speed in order to increase the air volume during operation, the noise of the fan will increase with the increase of the rotational speed of the mo...
