Below in conjunction with accompanying drawing, embodiment of the present utility model is described in further detail.
Fig. 1 is to Figure 3 shows that structural representation of the present utility model.
Reference character is wherein: end cap 1, housing 11, silicon steel stator 12, coil 13, bearing 14, silicon steel rotor 15, magnet steel 16, radiator shutter 17, wind scooper 2, first intake opening 2a, exhaust port 2b, convex body 2c, motor driving shaft 3, first fan blade 4, first impeller 4a, the first blade 4b, the first wind inlet 4c, inducer 5, wind guide vane 5a, wind-guiding dividing plate 5b, the second fan blade 6, second impeller 6a, the second blade 6b, the second wind inlet 6c, air intake cover 7, second intake opening 7a.
As shown in Figure 1 to Figure 3, the blower fan for vacuum cleaner of the present utility model, comprises motor and fan assembly.
Motor comprises the housing 11 be fixedly connected with end cap 1 and the silicon steel stator 12 be fixed in housing 11 and coil 13, the bearing 14 for mounted motor live axle 3, the silicon steel rotor 15 be located on motor driving shaft 3, the magnet steel 16 be sheathed on outside silicon steel rotor 15.
Bearing 14 is fixed with respectively in the inner side of the bottom of housing 11 and end cap 1.What motor driving shaft 3 can rotate is arranged on bearing 14, and the head of motor driving shaft 3 passes end cap 1.
Silicon steel rotor 15 is fixed on motor driving shaft 3, is provided with magnet steel 16 at silicon steel rotor 15 extenal fixation.Be provided with silicon steel stator 12 at housing 11 internal fixtion, the two ends of silicon steel stator 12 are provided with skeleton, and are provided with coil 13 by skeleton.
The end cap 1 of motor is provided with wind scooper 2.Be shaped with the first intake opening 2a in the middle part of the cover body end face of wind scooper 2, cover body perisporium is shaped with exhaust port 2b.The first fan blade 4 be connected with motor driving shaft 3 is provided with in the inside of wind scooper 2.Air intake cover 7 is installed outside wind scooper 2, in the middle part of the cover body of air intake cover 7, is shaped with the second intake opening 7a.Air intake cover 7 inside is provided with the second fan blade 6 be connected with motor driving shaft 3.The cover body end face of wind scooper 2 is fixed with inducer 5, and inducer 5 is shaped with the air-guiding aisle be communicated with the first intake opening 2a.
In a preferred embodiment, inducer 5 to comprise at least three cover body end faces being fixed on wind scooper 2 and the helically wind guide vane 5a of radiate and the wind-guiding dividing plate 5b that is fixed on wind guide vane 5a.Inducer 5 periphery between wind guide vane 5a, and is communicated with the first intake opening 2a by air-guiding aisle.
The cover body perisporium of wind scooper 2 is preferably shaped with multiple convex body 2c.Each exhaust port 2b is positioned at the side of each convex body 2c, makes each exhaust port 2b become helical arrangement, discharges with the air-flow adapting to helicity.
First fan blade 4 comprises two the first impeller 4a and to be fixed between two the first impeller 4a and the first blade 4b of helically radiate, is shaped with the first wind inlet 4c corresponding with the first intake opening 2a near the first impeller 4a of the first intake opening 2a.
