## Claims

### Claim 1

A hair dryer with a function of hair grooming, comprising:
a hollow air tube comprising a plurality of through holes cut through the periphery thereof, a connecting end portion located at one end thereof and an external end portion located at an opposite end thereof;
a connector connected to said connecting end portion of said hollow air tube, said connector defining therein a passage disposed in communication with the internal space of said hollow air tube;
two holder members respectively mounted in said passage of said connector said and said external end portion of said hollow air tube;
a cylindrical wire brush comprising a center rod, a plurality of coarse bristles and a plurality of fine bristles, said center rod suspended in said hollow air tube and having two opposite ends thereof respectively fastened to said two holder members, said coarse bristles and said fine bristles being fastened to the periphery of said center rod and inserted through said through holes and partially protruded over the outer perimeter of said hollow air tube;
a heat insulating cap capped on said external end portion of said hollow air tube; and
a grip connected to said connector, said grip comprising a switch, a fan and a fan motor, said switch being adapted for switching on/off said fan motor, said fan motor being adapted for rotating said fan to induce an airflow for enabling the induced said airflow to flow into said hollow air tube and then toward the outside of said hollow air tube via said through holes.
