The top output shaft of rheology frequency electrical connection of motor, the direct current variable frequency motor is connect with turbine flabellum, and turbine flabellum is located at
In the inner cavity of the shell connected at the top of lever, the top of the shell is connected with conveying air duct, the top in the conveying air duct
Portion is flexibly connected by screw thread with outlet air frame, and the inner cavity left and right ends of the outlet air frame are turned by two groups of shafts and vane out
Dynamic connection, the side wall of the lever are also provided with air inlet.
Preferably, the air outlet in the conveying air duct is connected with two groups of shafts.
Preferably, the top output shaft of the direct current variable frequency motor is flexibly connected by screw thread with turbine flabellum.
Preferably, the left and right ends of the vane out symmetrically offer the connector to match with two groups of shafts, and connect
Mouth is connected with the air hose in vane inner cavity out, is uniformly equipped with tuyere on the circumferential inner wall of the air hose at equal intervals.
Preferably, the tuyere is gradual shrinkage nozzle, and the air inlet of tuyere is connected with air hose.
It can be carried around compared with prior art, the utility model has the beneficial effects that the present apparatus is small in size, it is only necessary to be in one's hands
Installation battery makes motor rotation that flabellum rotation be driven to generate wind-force to be entered after frame from air outlet blowout simultaneously by air duct in handle
And drive surrounding air flowing, can be realized air-supply, air-flow is soft, operation noise is small, air supply direction and air output stabilization and
Uniformly, it can be used as common electric fan after while frame being dismantled to use.
