Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
Every other embodiment obtained, fall within the protection scope of the utility model.
Please refer to Fig. 1 and Fig. 2, the utility model provides a kind of technical solution: the utility model discloses a kind of oblique flow wind
Machine, including Fan casing 1, motor 2, impeller 3, silencer 4 and deflector 5, the Fan casing 1 include motor casing 11 and impeller housing
12, the motor casing 11 and impeller housing 12 are fixedly connected by fan supporter 14 with motor base 13, motor casing 11 and impeller housing
12 be the trapezoidal tubular of inner hollow, and the long side end of trapezoidal tubular of motor casing 11 is trapezoidal by screw thread rotation and impeller housing 12
The long side end connection of tubular, and the short end of the trapezoidal tubular of impeller housing 12 is air inlet 61, the short side of the trapezoidal tubular of motor casing 11
End is air outlet 62, and described 11 inner surface one end of motor casing is provided with deflector 5, and 5 longitudinal section of deflector is obtuse triangle,
The outside of the obtuse triangle be it is arc-shaped, reduce impact of the wind-force to diagonal flow fan shell inner surface, motor casing 11 risen
To certain defencive function, deflector 5 and the integrated structure of motor casing 11,11 inner surface of motor casing is far from deflector 5
One end is equipped with silencer 4, and there are six the settings of silencer 4, and it is symmetrical above and below be mounted on Fan casing inner surface, wherein in electricity
In casing 11 there are two installations, in impeller housing 12 there are four installations.
The motor 2 is arranged inside motor casing 11, and motor 2 is connect by connecting shaft 21 with impeller 3, and the impeller 3 is pacified
