     DETAILED DESCRIPTION OF THE INVENTION 
     Referring to  FIGS. 1-4 , a hair dryer with a function of hair grooming in accordance with the present invention is shown. The hair dryer with a function of hair grooming  10  generally comprises a hollow air tube  11 , a connector  21 , two holder members  31 , a cylindrical wire brush  41 , a heat insulating cap  51  and a grip  61 . 
     The hollow air tube  11  has a plurality of through holes  111  cut through the tube wall thereof, a connecting end portion  113  located at one end thereof, and an external end portion  115  located at an opposite end thereof. 
     The connector  21  is connected to the connecting end portion  113  of the hollow air tube  11 , comprising a passage  211  disposed in communication with the internal space of the hollow air tube  11 . 
     One holder member  31  is mounted in the connector  21  inside the passage  211 . The other holder member  31  is mounted in the hollow air tube  11  inside the external end portion  115  of the hollow air tube  11 . 
     The cylindrical wire brush  41  comprises center rod  411 , a plurality of coarse bristles  413  and a plurality of fine bristles  415 . The center rod  411  has the body thereof suspended in the hollow air tube  11  with the two opposite ends thereof respectively fastened to the two holder members  31 . The coarse bristles  413  and the fine bristles  415  are fastened to the body of the center rod  411 . Further, the coarse bristles  413  and the fine bristles  415  are inserted through the through holes  111  and protruded over the outer surface of the hollow air tube  11  at a predetermined distance. The coarse bristles  413  provide better support for hair grooming and scalp massaging. The fine bristles  415  are adapted for smoothening detailed portions of the hair. Further, the fine bristles  415  are less supportive, avoiding hair damage due to excessive pulling and enabling the hair dryer to achieve better grooming effects. 
     The heat insulating cap  51  is capped on the external end portion  115  of the hollow air tube  11 , preventing the user from scald accidents due to inadvertently touching heated part of the hair dryer. 
     The grip  61  is connected to the connector  21 , having mounted therein a switch  611 , a fan  613  and a fan motor  615 . The switch  611  is adapted for controlling the operation of the fan motor  615 . The fan motor  615  is adapted for rotating the fan  613 . 
     The air current created during rotation of the fan  613  flows through the passage  211  to the inside of the hollow air tube  11 , and then toward the outside of the hollow air tube  11  via the through holes  111 . 
     Thus, the hair dryer with a function of hair grooming  10  of the present invention can overcome the disadvantage of hindered and weakened of the prior art, enabling the generated airflow to be evenly delivered to the hair to dry and shape the focused area. 
     Further, the composition of the center rod  411 , coarse bristles  413  and fine bristles  415  of the cylindrical wire brush  41  enables the hair dryer with a function of hair grooming  10  of the present invention to achieve better hair grooming effects. 
     Further, in order to achieve better performance, the through holes  111  are preferably evenly distributed around the tube wall of the hollow air tube  11 , and arranged in multiple rows that are equiangularly spaced around the tube wall of the hollow air tube  11  between the connecting end portion  113  and the external end portion  115  in a staggered manner. 
     Further, the heat insulating cap  51  has a plurality of air vents  511 . The airflow induced by the fan  613  can flow through the air vents  511  toward the outside of the hair dryer. The arrangement of the air vents  511  prevents the problem of reduced airflow diversion due to air disturbance that occurs when the airflow that is continuously induced by the fan  613  to flow into the hollow air tube  11  is partially detained in the hollow air tube  11  and unable to completely flow out of the hollow air tube  11  through the through holes  111 . 
     Further, each holder member  31  comprises a plurality of partition plates  33  and a receptacle  35 . The partition plates  33  are connected to the outer perimeter of the receptacle  35 , defining a plurality of subspaces  331  around the receptacle  35  for the passing of the airflow that is induced by the fan  613 . The center rod  411  has two opposite ends thereof respectively fastened to the receptacles  35  of the two holder members  31 . 
     After explanation of the structure of the present invention, the application of the hair dryer with a function of hair grooming  10  is outlined hereinafter. 
     In application, the hair dryer with a function of hair grooming  10  is electrically connected to power supply. At this time, the user holds the grip  61  with one single hand, and then switches on the switch  611  to start up the fan motor  615 , rotating the fan  613  to induce airflow. Thereafter, the user moves the hair dryer with a function of hair grooming  10  toward the hair to be groomed, and then operate the hair dryer with a function of hair grooming  10  to dry and shape the hair with the coarse bristles  413  and the fine bristles  415  that protrude over the outer perimeter of the hollow air tube  11 . After grooming, use the same hand that holds the grip  61  to switch off the switch  611 , turning off the fan motor  615  and stopping the fan  613  from rotation, and thus, the hair dryer with a function of hair grooming  10  is returned to the original non-operation status.
