The invention discloses an axial flow fan and an air handling device with the axial flow fan. The axial flow fan comprises a central disc, a hub and blades. The surface, located on one side of the central disc in the rotary shaft line direction, of the central disc is a first plane, the hub is provided with a second plane, the blades comprise main body parts and blade roots, the outer outline edges of the main body parts comprise front edges, outer edges and tailing edges which are sequentially connected, the tailing edges comprise parallel segments, the parallel segments are parallel to at least one of the first plane and the second plane, two ends of the blades in the rotary shaft line direction are first ends and second ends, and the first ends are constructed by the parallel segments.According to the axial flow fan, the parallel segments are arranged on the tailing edges and parallel to at least one of the first plane and the second plane, when the blades are placed at the position in which the axial flow fan is placed, collision or friction between surfaces of the blades and the placing position can be reduced, so that the blades are protected, and the production yield rate of the axial flow fan is improved.
Description
technical field [0001] The invention relates to the field of household electrical appliances, in particular to an axial flow motor and an air treatment device having the same. Background technique [0002] Due to the large air volume, low noise, and low pressure, the axial flow wind wheel is widely used in air handling devices and various ventilation and heat dissipation environments. The design of the axial flow wind wheel has a great influence on the efficiency and noise of the fan. With the improvement of energy efficiency, the efficiency requirements of fans for heat dissipation are also higher, and the noise of the wind wheel is required to be low and the efficiency is high. The axial flow wind wheel is a key part in the outdoor unit of the air conditioner. The performance of the axial flow wind wheel has a great influence on the performance of the air conditioner. At the same time, the use of the axial flow wind wheel and the motor has a great impact on the efficiency ...
