In one embodiment, the air outlet direction of the air outlet gap 140 is opposite to the air outlet direction of the air outlet 320. In this embodiment, the air outlet gap 140 changes the direction of the air flow by the emitted high-speed air flow flowing along the air flow guiding portion under the coanda effect. The air outlet direction of the air outlet gap 140 is opposite to the air outlet direction of the air outlet 320, which is equivalent to that the air flow flowing out of the air outlet gap 140 turns around and blows to the air outlet 320 under the action of the air flow guiding part.

Since the air outlet gap 140 is located on the outer side surface of the inner cylinder wall 120, the air flow emitted at high speed passes through the edge of the air inlet 310 under the action of the air flow guiding portion, is guided into the air duct, and is blown out from the air blowing port 320, so that an object close to the edge of the air inlet 310 can be blown into the air duct. When the hair dryer is used for blowing hair, the air inlet 310 of the hair dryer can be close to the scalp, the air current ejected at high speed can blow the hair into the air duct and blow the hair out of the air outlet 320, so that the hair is blown straight under the driving of the air current, and the hair is dried from the root of the hair. Not only dry hair with high efficiency and good effect, but also has good interest.
In accordance with the foregoing, the present application also provides a hair dryer.
A hair dryer is provided with the barrel of any of the embodiments described above.
When the air inlet 310 of the hair dryer is close to the scalp, the air current emitted at high speed blows the hair into the air duct and blows the hair out of the air outlet 320, so that the hair is blown straight by the air current, and the hair is dried from the root of the hair. Because the blown wind blows from the scalp to the direction of the hair tip, hot wind does not blow on the face, and people feel uncomfortable. In addition, because the mode of blowing of hair-dryer is that blow in the section of thick bamboo of blowing with the hair to blow the hair straight under the drive of high velocity air, consequently the girl generally need not to hang down and use the hair-dryer to blow the hair after making long hair flagging, directly will blow a section of thick bamboo of blowing and paste on the head blow can, it is more convenient to use. Meanwhile, when the hair is blown, only one hand is needed for operation, and the other hand is not needed for participating in the action of blowing the hair by pulling the hair apart, so that the hair-blowing device is easier to operate, saves more labor and has good interestingness.
The above examples only show some embodiments of the present invention, and the description thereof is more specific and detailed, but not construed as limiting the scope of the invention. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the inventive concept, which falls within the scope of the present invention. Therefore, the protection scope of the present patent shall be subject to the appended claims.
