Abstract

The invention discloses a fan with damping bases. The fan with the damping bases comprises a centrifugal fan and a motor driving the fan. The centrifugal fan comprises an impeller and an air outlet head which is arranged on the impeller tangentially, the motor comprises a head and an aluminum radiator used for radiation of the head, the centrifugal fan and the motor are connected through a coupling, the motor comprises a first damping base, and the centrifugal fan comprises a second damping base. The first damping base and the second damping base are both elastic flat plates, each elastic flat plate comprises a metal flat plate located at the bottom of the elastic flat plate and an elastic material layer attached onto the metal flat plate, each of the metal flat plates and the elastic material layers comprises through holes for positioning, and the elastic materials are optionally elastic high-damping rubber materials and silicone elastic rubber. By means of the technical scheme, noise vibration of the fan can be greatly lessened by the aid of the detachable damping bases positioned on a foundation, and the fan with the damping bases is low in cost and simple in structure.

Description

[0001] technical field [0002] The present invention relates to a fan, more specifically, to a fan device capable of effectively using noise. [0003] Background technique [0004] As a common workshop equipment, fans are used to cool processed metal workpieces. However, the fan used in the existing workshop has huge vibration and noise, which affects the work of the workshop. Simultaneously, the casing of existing blower fan is all formed in one piece, once damaged maintenance is very difficult. [0005] Chinese invention patent application ZL201010121360.9 discloses a fan impeller, the fan impeller includes: a substantially cylindrical cup; and a plurality of blades, the plurality of blades are arranged on the outer peripheral surface of the peripheral wall of the cup superior. The cup portion includes a plurality of axially extending first ribs and a plurality of second ribs disposed between the first ribs on an inner peripheral surface of a peripheral wall portion t...
