An axial flow fan

Abstract

The invention relates to the technical field of fan application, specifically an axial flow fan, including a bottom plate, a support disc, a support foot, a limit bar, a spring, a guide cylinder, a straight rod, a casing, a strip, and a bearing block , bearings, round shafts, bearing discs, through slots, grooves, filter screens, screws, connecting rods, fixed sleeves, mounting plates, motors and fan blades. The structure of the invention is reasonable, and the height of the fan body can be adjusted through the cooperation of the guiding structure and the lifting load-bearing structure, so as to meet the needs of different heights. At the same time, the components for completing the lifting are relatively simple. When operating, only the fan body needs to be manually adjusted. Lifting and rotation of the circular shaft are all that is needed, and the operation is simple and convenient to use; through the cooperation of several elastic buffer structures, it can effectively elastically connect the surroundings of the supporting disc, and can effectively buffer and reduce the impact when it is impacted. Shock, reducing the impact of the overall structure, to achieve protection.

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...
