Embodiment Construction

[0040] The content of the present invention will be further described in detail below in conjunction with specific embodiments:

[0041] In order to achieve the purpose of the present invention, a double-head fixed axial flow fan includes: a motor body with a rotating shaft 3 that outputs rotational power; the motor body includes a stator 17 and a rotor 4; a fan blade 7 assembled with one end of the rotating shaft 3; The fixed bearing includes a head end bearing 1 and a tail end bearing 2 respectively arranged at the two shaft ends of the rotor 4. The head end bearing 1, the tail end bearing 2 and the shaft 3 are coaxially fixed; the casing is wrapped on the outside of the motor body, and the head end bearing 1. The end bearing 2 is respectively wrapped by the first wrapping ring 13 and the tail wrapping ring 11. The first wrapping ring 13 and the tail wrapping ring 11 are respectively fixed to the casing by the deflector 14 and the connecting rib 8 between adjacent connecting rib...

Abstract

The invention discloses a double-head fixing type axial flow fan. The axial flow fan comprises a motor body, fan blades, a fixing bearing, and a machine shell, wherein the motor body is provided witha rotating shaft outputting rotating power, and the motor body comprises a stator and a rotor; the fan blades are assembled to one end of the rotating shaft; the fixing bearing comprises a head end bearing, and a tail end bearing which are arranged at the two axial ends of the rotor, and the head end bearing and the tail end bearing are fixed coaxial with the rotating shaft; the machine shell is wrapped on the outer side of the motor body; and the head end bearing and the tail end bearing are wrapped by a head wrapping ring and a tail wrapping ring respectively, the head wrapping ring and thetail wrapping ring are fixed to the machine shell through flow guiding pieces and connecting ribs, a hollow part is formed between the adjacent connecting ribs, and the machine shell forms a through air channel parallel to the axis direction of the rotating shaft. According to the double-head fixing type axial flow fan, the rotating shaft of the motor is limited by two bearings which are relatively far away from each other, and the two bearings are firmly fixed, so that vibration and jitter during operation of the axial flow fan can be controlled, and the influence of the arranged bearings onoverall wind resistance is very small.

Description

Technical field [0001] The invention relates to the field of fan motors, in particular to a double-head fixed axial flow fan. Background technique [0002] The current hair dryers on the market have a single-pick structure, that is, the rotating shaft connecting the fan blades is similar to a one-way cantilever structure. The length of this cantilever structure is determined by the inherent design, and the overall vibration of the fan blade is large during the transmission process. The noise generated will reduce the experience and also reduce the service life. Summary of the invention [0003] The problem to be solved by the present invention is to provide a double-head fixed axial flow fan, the motor shaft is limited by two relatively far apart bearings, and both bearings are firmly fixed, so the vibration of the axial flow fan can be controlled during operation Jitter, and the set bearing has little effect on the overall wind resistance. [0004] In order to solve the above pr...
