Claims

1. A hair dryer, comprising:

2. The hair dryer of claim 1, wherein said first motor blade assembly includes a first motor and a first blade, said first motor driving said first blade to rotate about a first output axis of said first motor; the second motor blade assembly comprises a second motor and a second blade, and the second motor drives the second blade to rotate around a second output axis of the second motor;

the first output axis is parallel to the second output axis.

3. The hair dryer of claim 1, wherein said motor blade assembly further comprises an inner duct, said inner duct is disposed inside said outer duct, and said blow pipe is connected to an end of said inner duct near said air outlet end.

4. The hair dryer of claim 3, wherein the motor blade assembly further comprises a diversion cone, and the diversion cone is mounted at one end of the inner duct close to the air outlet end.

5. The hair dryer of claim 1, wherein said blow tube is formed by joining two juxtaposed tubes, the lumen of each of said tubes serving as one of said air-guiding passages.

6. The hair dryer of claim 1, further comprising a blowing nozzle, wherein the blowing nozzle is provided with a connecting end and a blowing opening arranged opposite to the connecting end, the connecting end of the blowing nozzle is connected with one end of the blow pipe far away from the outer duct, and the blowing nozzle is designed to converge the air blown out from the first air guide channel and the second air guide channel and then blow out from the blowing opening.

7. The hair dryer of claim 6, wherein the shape of the air blowing opening comprises a circular hole, an oblong hole or a shape formed by butt joint of end points of two major arcs with equal radius.

8. The hair dryer of claim 6, wherein said air outlet is divided into two separate sub air outlets, each of said sub air outlets communicating with one of said air guide passages.

9. The hair dryer of claim 1, wherein said motor blade assembly further comprises a third motor blade assembly, said third motor blade assembly juxtaposed with said first motor blade assembly and said second motor blade assembly.

10. The blower of claim 9, wherein said blow tube further includes a third air deflection passage, said first air deflection passage, said second air deflection passage and said third air deflection passage being independently disposed, said third motor blade assembly being in communication with said third air deflection passage such that air generated by said third motor blade assembly flows along said third air deflection passage.

11. The hair dryer of claim 10, wherein said blow tube is formed by joining three tubes arranged in parallel, the lumen of each of said tubes serving as one of said air guide channels.

12. The hair dryer of claim 9, wherein said first motor blade assembly includes a first motor and a first blade, said first motor driving said first blade to rotate about a first output axis of said first motor; the second motor blade assembly comprises a second motor and a second blade, and the second motor drives the second blade to rotate around a second output axis of the second motor; the third motor blade assembly comprises a third motor and a third blade, the third motor drives the third blade to rotate around a third output axis of the third motor, and the third output axis is parallel to the first output axis and the second output axis.

13. The hair dryer of claim 10, further comprising a blowing nozzle, wherein said blowing nozzle has a connecting end and a blowing opening opposite to said connecting end, the connecting end of said blowing nozzle is connected to an end of said blow pipe remote from said bypass, and said blowing nozzle is designed to converge the air blown from said first air guiding passage, said second air guiding passage and said third air guiding passage and blow the air through said blowing opening.

14. The hair dryer of claim 1, further comprising an air duct disposed within the housing, wherein the air duct is located between the air inlet end and the outer duct, and the air duct is connected to an end of the outer duct near the air inlet end.

15. The hair dryer of claim 14, wherein the air duct is flared, and a cross-sectional area of an opening at an end of the air duct near the air inlet end is larger than a cross-sectional area of an opening at an end of the air duct near the air outlet end.
