BACKGROUND OF THE INVENTION
1. Field of the Invention
[0001] The present invention relates to hair dryer technology and
more particularly, to a hair dryer with a function of hair
grooming.
2. Description of the Related Art
[0002] When wishing to use a hairpin, hair care product or hair
sculpting lotion during the use of a hair dryer and a hairbrush for
hair drying and shaping, you must keep your one hand off the
hairbrush or hair dryer for picking up the desired item while your
other hand is working. The user using the both hands in this manner
is likely to cause a rush.
[0003] Taiwan Patent M521373 discloses an improved structure of
hair dryer. This design of hair dryer provides an air outlet for
guiding out induced air for drying hair and a cylindrical wire
brush for grooming hair, avoiding the inconvenience of the
operation manner of holding the air dryer with one hand and the
hairbrush with the other hand.
[0004] However, in the aforesaid prior art design, the air outlet
is disposed in between the cylindrical wire brush and the housing
of the hair dryer. When drying and grooming the hair, the induced
airflow can be hindered and weakened by the user's hair and the
bristles of the cylindrical wire brush, causing the hair drying and
shaping effect to be limited to the area near the air outlet and
affecting the hair drying and shaping performance of the hair
dryer.
[0005] Accordingly, the present applicant believes that this
structure must be improved to overcome the shortcomings of this
technology.
SUMMARY OF THE INVENTION

circumstances in view. It is the main object of the present
invention to provide a hair dryer with a function of hair grooming,
which enables the generated airflow to be evenly delivered to the
hair to dry and shape the focused area.
[0007] It is another object of the present invention to provide a
hair dryer with a function of hair grooming, which achieves better
hair grooming effects.
[0008] To achieve these and other objects of the present invention,
a hair dryer with a function of hair grooming comprises a hollow
air tube having through holes spaced around the periphery thereof,
a connector connected to a connecting end portion of the hollow air
tube and defining therein a passage in communication with the
inside space of the hollow air tube, two holder members
respectively mounted in the passage of the connector and the

DETAILED DESCRIPTION OF THE INVENTION
[0016] 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.
[0017] 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.
[0018] 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.
[0019] 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.
[0020] 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.
[0021] 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.
[0022] 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.
[0023] 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.
[0024] 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.
[0025] 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.
[0026] 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.
[0027] 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.
[0028] 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.
[0029] 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.
[0030] 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.
