Problems solved by technology

[0003] When the axial flow fan of the prior art is in use, the air flow easily sucks larger debris into the fan, causing damage to the blades of the fan and increasing the failure rate of the fan. Not only that, but when the fan of the prior art is in use, the fan It is easy to generate vibration, so that the bolts used to fix the fan are easy to loosen, resulting in unstable installation of the fan and reducing the practicability of the fan

Abstract

The invention relates to a vibration-reducing axial flow fan with protection function, which includes a main body, a motor, a drive shaft and fan blades, and also includes a protection mechanism and an anti-shake mechanism. The protection mechanism includes a mounting bearing, a connecting shaft, a cleaning brush, detection assembly, two fixed sleeves, two fixed rods, two second springs, two protective nets and two friction blocks; The vibration damping assembly includes a support sleeve, a support rod and a third spring, and the detection assembly includes a sliding sleeve, a first spring, a thrust plate, two fixed pulleys, and two connecting wires. In the axial flow fan, through the protective function of the protective mechanism, the probability of large debris being sucked into the fan is reduced, and the failure rate of the fan is reduced. The vibration of the fan is reduced through the anti-shake mechanism, and the loosening of the fan installation is reduced. The chance of improving the stability of fan installation.

Description

technical field [0001] The invention relates to the field of fans, in particular to a vibration-damping axial flow fan with protection function. Background technique [0002] Axial flow fans have a wide range of uses, that is, the airflow in the same direction as the axis of the fan blades, such as electric fans and air conditioner external fans are axial flow fans. It is called "axial flow" because the gas flows parallel to the shaft of the fan. Axial flow fans are usually used in occasions with high flow requirements and low pressure requirements. Axial fans hold the position and move the air. The axial flow fan is mainly composed of the fan impeller and the casing. The structure is simple but the data requirements are very high. [0003] When the axial flow fan of the prior art is in use, the air flow easily sucks larger debris into the fan, causing damage to the blades of the fan and increasing the failure rate of the fan. Not only that, but when the fan of the prior ...
