Medial wall connects, and is provided with external wind wheel 21 in the lateral wall of described fan blade clamping ring 22；Described external wind wheel 21 and the shape of interior fan blade 23
Shape is sickleshaped, and the face wind end at external wind wheel 21 and interior fan blade 23 is provided with some serrated slot 25, the degree of depth of described serrated slot 25 with
Direction away from blade root increases；Preferably, the blade quantity of described external wind wheel 21 and interior fan blade 23 is 5～9, described interior fan blade
23 and the angle of external wind wheel 21 and motor shaft 10 sagittal plane be 35 °, the degree of depth of described serrated slot 25 is 5～10 millimeters, fan blade 2
When rotated, from blade root more away from the air-flow that produces the biggest, the air-flow near blade root is separated, far by shallower serrated slot 25
Air-flow from blade root is rolled into a ball and is cut into little eddy current by deeper serrated slot 25, and therefore the degree of depth of serrated slot 25 is with the side away from blade root
To increase, can more effectively cutting steam group so that it is closer to PERFECT GAS FLOW.
Further, at described air inlet 72, it is provided with drainage screen 6, is so possible to prevent dust to enter shadow in motor casing 11
Ring Heagting fan 8 and the service life of heater 5；Described heater 5 can be PTC, it is also possible to be heating wire, heating efficiency
High.
Refer to Fig. 3, in another embodiment, double fan blade fans of a kind of warm in addition to as characterized above,
Further, described column 14 has double-decker, and column outer layer 142 is connected with described base 16, and column internal layer 141 is with described
Motor casing 11 connects, and described column internal layer 141 can the most telescopically be arranged in described column outer layer 142.
Referring to Fig. 4, the operation principle of above-described embodiment is as follows: when needing hot blast, and heater 5 is energized by electric-controlled plate 15
And starting heating, Heagting fan 8 works simultaneously, and extraneous air enters heater 5 by air inlet 72 and drainage screen 6 and is heated intensification
After, air outlet 71 is discharged；When needs greater area of hot blast when, it is also possible to by electricity in the case of heater 5 is opened
Control plate 15 is opened blade motor 9 and is adjusted to suitable rotating speed, is delivered in larger range of space by hot blast by fan blade 2；Only
When need to dry, only opening blade motor 9 by electric-controlled plate 15 and be adjusted to suitable rotating speed, the present invention just can make as conventional fan
With.
The invention has the beneficial effects as follows: make the fan not only can be for fall of enjoying the cool sweltering heat when by the setting of heater
