Embodiment 1

[0010] Embodiment 1: as figure 1 , figure 2 As shown, the integrated air duct frame body 1 includes the flow-guiding stationary blade 11 and the axial-flow moving blade 4 and the bearing portion 12 of the driving device 5, as a single component, which is injection molded at one time. The axial-flow moving blade 4 and its driving device 5 are carried on the bearing part 12 in the integrated air duct frame body 1, and the height of the bearing part 12 in the integrated air duct frame body 1 is set appropriately, so that the flow guide The minimum distance between the stationary blade 11 and the axial-flow moving blade is set between 10mm-50mm, preferably 30mm, and the running noise is low.

Embodiment 2

[0011] Embodiment 2: Due to the difference in the driving device 5 of the axial-flow moving blade 4, the raised bearing part 12 in the integrated air duct frame 1 changes as follows image 3 , Figure 4 As shown, the integrated air duct frame body 1 is still used as a single component, and is injection molded at one time. The driving device 5 of the axial-flow rotor blade 4 is carried inside the carrying portion 12 . Likewise, by properly setting the height of the bearing portion 12 in the integrated air duct frame 1 , the minimum distance between the flow-guiding stationary blade 11 and the axial-flow moving blade 4 can be set between 10 mm and 50 mm. The minimum distance is preferably 30 mm.

Abstract

The invention discloses a component capable of generating airflow, which is suitable for a bladeless electric fan. The component comprises axial flow type dynamic blades and a driving device of the axial flow type dynamic blades, an integrated air flue frame body. A bearing part for the axial flow type dynamic blades and the driving part of the axial flow type dynamic blades is a bulge part extended from the center part of static blades for stream guiding in the integrated air flue frame body. The integrated air flue frame body is a single part, so the manufacturing cost is low; the minimum spacing between the axial flow type dynamic blades and the static blades for stream guiding is set within 10 mm to 50 mm, and the running noise is low.

Description

technical field [0001] The invention relates to a fan assembly for generating air flow in a bladeless electric fan. Background technique [0002] The fan assembly for generating air flow in the existing bladeless electric fan includes a stationary blade for air guiding and its air channel frame, a motor-driven mixed-flow impeller and its air channel frame, and a motor. The process of generating air flow by this component is as follows: the motor drives the mixed-flow impeller to rotate to generate air flow, which passes through the air channel frame of the mixed-flow impeller and enters the air channel frame of the flow-guiding stationary blade, and then passes through the flow-guiding stationary blade to be distributed into the corresponding duct. The air channel frame body of the mixed-flow impeller and the air channel frame body of the flow-guiding stationary blade are split structures, the structure is complex, the air channel is not smooth, the manufacturing cost is hi...
