Axial flow fan

Abstract

The invention relates to the technical field of fan application, in particular to an axial flow fan. The axial flow fan comprises a bottom plate, a supporting disc, supporting feet, limiting blockingstrips, springs, a guide cylinder, a straight rod, a machine shell, a long strip, a bearing tooth block, a bearing, a round shaft, a bearing disc, a through groove, a groove, a filter net, a screw, aconnecting rod, a fixed sleeve, a mounting plate, a motor and fan blades. The axial flow fan is reasonable in structure, through cooperative effect of a guide structure and a lifting bearing structure, the height of a fan body can be adjusted, the fan can adapt to needs of different heights, meanwhile, lifted assemblies are simple, during operation, a worker only needs to lift up the fan body androtate the round shaft, operation is easy, use is convenient, through cooperative effect of multiple elastic buffer structures, the periphery of the supporting disc can be effectively elastically connected, during impact, the buffer and damping can be effectively carried out, the impact force of the whole structure is reduced, and protection is achieved.

Description

technical field [0001] The invention relates to the technical field of fan application, in particular to an axial flow fan. Background technique [0002] Axial 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 fans are axial flow fans; the reason why it is called "axial flow" is because the gas is parallel to the fan shaft flow. [0003] Axial flow fans have a wide range of applications, and can be used for ventilation and air drying; existing axial flow fans may lack a lifting structure, which is not convenient for height adjustment, so it is not convenient to meet the needs of blowing at different heights; at the same time, there may be a lack of buffering The shock-absorbing structure may be subjected to a large impact force after being impacted, and is prone to damage. Therefore, an axial flow fan is proposed aiming at the above problems. Contents of the invention [00...
