Description
BACKGROUND
[0001] With the development of society, hair styling has become a
lifestyle in the pursuit of beauty of people, thus various hair
styling tools have come into being, such as hair straighteners,
hair curlers and the like. The hair curler is a hand-held
electronic product used for curling hair, and main components
thereof are a handle and a heating drum. In the design of the hair
curler, a circuit panel is used for controlling the temperature,
and the heating drum is made of a tourmaline ceramic panel, which
can averagely disperse heat, circularly heat, improve hair protein
structures to generate curls and protect the hair during the

manual hair curlers are used for curling hair at home, it can be
completed only with the help of others, so the operation is
inconvenient. If the semiautomatic hair curlers are operated by the
users themselves, they have to choose hair curlers with clips,
because hair curlers without clips are difficult to operate by the
users themselves, and thus having certain limitation in use.

DETAILED DESCRIPTION
[0013] Embodiments of the present disclosure relate generally to
hair styling tools, and particular embodiments relate to an
automatic hair curler.
[0014] Automatic hair curlers according to embodiments of the
present disclosure, which can achieve automatic hair curling, may
improve hair curling efficiency while also being simple to
operate.
[0015] According to embodiments of the present disclosure, an
automatic hair curler may include a handle, a hair curling
component installed on the handle. The hair curling component may
include a shell arranged on the handle, a heating rod arranged on
the handle and a rotating seat that is sleeved at the outside of
the heating rod and rotatable relative to the heating rod. A hair
curling cavity with an upper end opening may be formed between an
inner surface of the rotating seat and an outer surface of the
heating rod. A notch extending downwards from a top end face of the
shell for placing hair may be formed at an upper end of the shell,
where the notch may be communicated with the opening of the hair
curling cavity. A shifting part for shifting the hair to wind the
hair on the heating rod when the rotating seat rotates may be
arranged on the rotating seat. The automatic hair curler may also
include a driving device used for driving the rotating seat to
rotate relative to the heating rod. When hair is inserted into a
hair curling cavity of the automatic hair curler and the driving
device drives the rotating seat, one or more features on the
rotating seat (e.g., a shifting part or a positioning elastic part)
may wind the hair around the heating rod as the heating rod is
heated, thereby automatically curling the inserted hair.
[0016] The driving device may include a motor installed on the
handle, a mounting shaft fixedly connected with the handle, a
bearing for pivoting the rotating seat on the mounting shaft and a
gear that is fixed on the rotating seat and is synchronously
coupled with a rotating shaft of the motor. The heating rod may be
installed at an upper end of the mounting shaft.
[0017] A rotating seat may include a sleeving part that is sleeved
on an outer ring of the bearing and fixedly connected with the
outer ring of the bearing and a shifting piece distributed on the
periphery of the sleeving part, where the hair curling cavity may
be located between an inner surface of the shifting piece and the
outer surface of the heating rod.
[0018] A shifting part may be composed of projections that are
convexly arranged on a side wall of the shifting piece, and a
positioning elastic part may be arranged on an inner wall of the
shifting piece.
[0019] An elastic piece gradually inclined outwards from bottom to
top may be arranged at an upper end of the shifting piece, and the
shifting part may be located at a juncture of the shifting piece
and the elastic piece.
[0020] The automatic hair curler may further include a cover body
installed at a top end of the heating rod, where an outer surface
of the cover body is an arc surface.
[0021] According to embodiments of the present disclosure, hair may
be put in a notch formed in the shell of an automatic hair curler,
and since the notch is communicated with the opening of the hair
curling cavity, the hair put in the notch can enter the hair
curling cavity, and the shifting part can wind the hair on the
heating rod during rotation of the rotating seat to achieve
automatic hair curling in a simple operation. In addition, due to
the arrangement of the shell and the rotating seat, the heating rod
may be effectively prevented from scalding a user, and thus may be
safer to use when compared with prior art hair curlers.
[0022] Specific embodiments according to the present disclosure
will be further described below in combination with the
drawings.
[0023] An automatic hair curler, as shown in FIG. 1 to FIG. 4, may
include a handle 10, a hair curling component installed on the
handle 10 and a driving device. When in use, under the action of
the driving device, the hair curling component starts working to
accomplish a hair curling process, and since a user holds the
handle 10, scalding may be avoided.
[0024] The hair curling component may include a shell 20, a heating
rod 30 and a rotating seat 40. The shell 20 may extend at least
partially around (and up to entirely around) the circumference of
the heating rod 30, and may extend a height axially overlapping the
entire height of the heating rod 30. The shell 20 may be radially
spaced from the heating rod 30, such that hair may be inserted
between the shell 20 and the heating rod 30. In some embodiments,
the rotating seat 40 may be disposed between the heating rod 30 and
the shell 20, wherein the heating rod 30, rotating seat 40 and
shell 20 may be radially spaced apart from each other, and wherein
hair may be inserted between the heating rod 30 and the rotating
seat 40. The rotating seat 40 may extend at least partially around
a circumference of the heating rod 30 and may extend a height from
the handle 10 that at least partially overlaps the heating rod
30.
[0025] FIG. 1 shows a partial sectional view of an automatic hair
curler according to embodiments of the present disclosure, where a
portion of the shell 20 is sectioned to show the internal features,
including the heating rod 30 and the rotating seat 40. As shown, a
shifting part 41 for shifting hair may be arranged on the rotating
seat 40. Both of the heating rod 30 and the shell 20 are fixed on
the handle 10, while the rotating seat 40 is sleeved around the
outside of the heating rod 30 and can rotate relative to the
heating rod 30 under the drive of the driving device. Meanwhile, a
hair curling cavity 60 used for curling the hair can be formed
between an outer surface of the heating rod 30 and an inner surface
of the rotating seat 40, where an upper end of the hair curling
cavity 60 is open. In addition, a notch 21 communicated with the
hair curling cavity 60 is formed on the shell 20, where the notch
21 extends from a top end face of the shell 20 downwards. In this
way, during use by the user, the hair may be put in the hair
curling cavity 60 from the notch 21, and under the drive of the
driving device, the rotating seat 40 starts rotating. Since both of
the shell 20 and a mounting shaft 52 are fixed relative to the
handle 10, a shifting part 41 arranged on the rotating seat 40 can
wind the hair on the heating rod 30 with the rotation of the
rotating seat 40, where a curling effect of the hair wound on the
heating rod 30 can be achieved in a continuous heating process of
the heating rod 30. Furthermore, due to the arrangement of the
shell 20 and the rotating seat 40, the user can be effectively
isolated from a heat source of the heating rod 30 to avoid scalding
the user by the heating rod 30 in a hair curling process, thus
being safer to use.
[0026] FIG. 2 shows a cross sectional view of the hair curler shown
in FIG. 1. As shown in FIG. 2, a driving device of the hair curler
may include a motor 51, the mounting shaft 52, a bearing 54 and a
gear 53. The motor 51 may be installed on the handle 10, and the
gear 53 may be fixedly connected with the rotating seat 40, where
the gear 53 is synchronously coupled with a rotating shaft of the
motor 51. In addition, the mounting shaft 52 may be fixed to the
handle 10, the heating rod 30 may be fixed at the upper end of the
mounting shaft 52, and the rotating seat 40 may be pivoted on the
mounting shaft 52 by the bearing 54. In this way, under the drive
of the motor 51, the gear 53 starts rotating, and the rotating seat
40 can rotate under the action of the gear 53 and the bearing 54,
and the rotating seat 40 can stably rotate relative to the heating
rod 30.
[0027] As shown in FIG. 3, a rotating seat 40 may include a
sleeving part 43 and a shifting piece 44, where the shifting piece
44 is distributed on the periphery of the sleeving part 43 and
extends outwardly from the sleeving part 43. The sleeving part 43
may be sleeved on an outer ring of the bearing 54 and fixedly
connected with the outer ring of the bearing 54. A hair curling
cavity 60 can be formed by the inner surface of the shifting piece
44 and the outer surface of the heating rod 30 in cooperation, so
the entire structure is more stable.
[0028] The shifting piece 44 may extend at least partially around a
circumference of sleeving part 43 (such that the shifting piece may
extend at least partially around an assembled heating rod). For
example, in the embodiment shown in FIGS. 3 and 4, two shifting
pieces 44 may be spaced apart around the circumference of the
sleeving part 43, thereby extending less than the entire
circumference of the sleeving part 43. In some embodiments, one or
more shifting pieces may extend the entire circumference around the
sleeving part or less than the entire circumference of the sleeving
part. Further, the shifting piece 44 may include at least one
shifting part 41, where shifting parts 41 may be formed of
projections that are convexly arranged as part of a side wall of
the shifting piece 44. Shifting parts 41 may help shifting or
otherwise maneuvering of hair inserted into the automatic hair
curler. Meanwhile, a positioning elastic part 42 may be arranged on
an inner wall of the shifting piece 44, so the hair can be wound on
the heating rod 30 more smoothly in a hair curling process, and
accordingly, the hair curling effect may be better. The positioning
elastic part 42 may extend inwardly from the side wall of the
shifting piece 44, such that the positioning elastic part 42 may
extend into the hair curling cavity 60 formed between the inner
surface of the shifting piece 44 and the outer surface of the
heating rod 30.
[0029] In some embodiments, a rotating seat may adopt the structure
as shown in FIG. 4, where an elastic piece 45 may be arranged at an
upper end of the shifting piece 44. The elastic piece 45 may
gradually incline outwards from the upper end of the shifting piece
44, inclining in a direction from a bottom of the elastic piece to
a top of the elastic piece. The elastic piece 45 may have certain
flexibility, and thus may shake during rotation of the rotating
seat 40 and may also play a certain combing function on the hair,
so as achieve the effect of winding the hair on the heating rod 30
more smoothly. The shifting part 41' may be located at a juncture
of the shifting piece 44 and the elastic piece 45. The positioning
elastic part and the elastic piece described above may be made of a
silica gel material or such elastic materials as rubber blocks or
plastic blocks, etc.
[0030] According to some embodiments of the present disclosure, an
automatic hair curler may include a handle, a heating rod extending
from the handle, a rotating seat extending at least partially
around the heating rod, a hair curling cavity formed between an
inner surface of the rotating seat and an outer surface of the
heating rod, a motor installed in the handle, a mounting shaft
fixedly connected to the handle, and a gear fixed on the rotating
seat and synchronously coupled with a rotating shaft of the motor,
wherein the heating rod is installed at an upper end of the
mounting shaft. A sleeving part of the rotating seat may be sleeved
around at least a partial axial length of the mounting shaft, such
that the sleeving part may be axially retained to the handle of the
automatic hair curler and rotatable around the mounting shaft. For
example, the hair curler shown in FIG. 2 includes a mounting shaft
52 fixed to the handle and a heating rod 30 fixed to the mounting
shaft 52. A rotating seat 40 is disposed around at least a portion
of the heating rod 30 and rotatably retained to the handle.
Particularly, a sleeving part of the rotating seat 40 may be
sleeved around at least a partial axial length of the mounting
shaft 52 and rotatable around the mounting shaft 52 by gear 53 when
driven by the motor 51. In some embodiments, the diameter of the
heating rod 30 may be greater than the diameter of the mounting
shaft 52, whereby the diameter of the heating rod may act to
axially retain the sleeving part of the rotating seat 40. In some
embodiments, one or more gears 53 may act to axially retain the
sleeving part of the rotating seat 40 to the handle.
[0031] In some embodiments, such as shown in FIGS. 1 and 2, a
bearing 54 may be disposed between a mounting shaft 52 and a
sleeving part 43 of a rotating seat 40, where the bearing 54 may be
fixed to either the mounting shaft 52 or the sleeving part 43. In
some embodiments, an outer surface of a mounting shaft and/or an
inner surface of a sleeving part may be coated with a bearing
material, such as a reduced friction material, where the coated
surface may act as the bearing between the mounting shaft and the
sleeving part of a rotating seat.
[0032] As shown in FIGS. 1 and 2, an automatic hair curler may
further include a cover body 31 installed at a top end of the
heating rod 30. An outer surface of the cover body 31 may be an arc
surface, which may provide a better guide function for the hair in
the hair curling process.
[0033] While the present disclosure has been described with respect
to a limited number of embodiments, those skilled in the art,
having benefit of this disclosure, will appreciate that other
embodiments may be devised which do not depart from the scope of
the disclosure as described herein. Accordingly, the scope of the
disclosure should be limited only by the attached claims.
