Background

Axial flow fans are airflow in the same direction as the axis of the fan blades, such as electric fans, and fans outside air conditioners are axial flow running fans. The "axial flow" is so called because the gas flows parallel to the fan axis. Axial flow fans are typically used in applications where flow requirements are high and pressure requirements are low. At present axial fan still exists the phenomenon that the vibration produced the noise in the use, and this kind of phenomenon is mostly because the flabellum produces when rotating and rocks and arouses the noise, and the flabellum is stable inadequately, and current processing scheme is that 20mm thickness's amortization is cotton at axial fan support's surface paste, and the defect of handling like this is obvious, and the vibration of the unstable production of flabellum still exists. In view of the above, we propose an axial flow fan with a noise reduction function to solve the above problems.

Furthermore, the dryer is the cylinder hollow structure of both ends open-ended, and the dryer is inside including skin, middle level, inlayer and multilayer amortization cotton, all is equipped with amortization cotton between skin and the middle level and between middle level and the inlayer and is used for the noise absorption to fall and makes an uproar.

Furthermore, a plurality of honeycomb structures are arranged on the surface of the inner wall of the air duct and used for absorbing and reducing noise.

Furthermore, the interior of the hub is of a hollow structure and used for reducing the overall weight of the fan.

Furthermore, a plurality of fixing pieces are arranged between the motor and the air duct and used for fixing the motor on the air duct.

Further, the motor both ends all are equipped with the mounting, are equipped with a plurality of bolts on the mounting, and the both ends of mounting are passed through bolt difference fixed connection on motor and dryer.

Compared with the prior art, the utility model the advantage lie in: the utility model discloses set up the fixed plate of strengthening its stability between flabellum tip and wheel hub, avoided the flabellum to rotate the too big noise that produces of in-process vibration range, in addition the utility model discloses establish the dryer into multilayer structure to set up multilayer amortization cotton in its inside and carry out noise absorption, and set up a large amount of honeycomb structure at the dryer inner wall and carried out noise absorption and fall, multiple mode combination has improved the noise reduction effect greatly.
