Description
TECHNICAL FIELD
[0001] The present invention relates to a brush having a heater
embedded therein and more particularly to a brush having a heater
embedded therein capable of preventing damage to the skin by
preventing the generated heat from coming into direct contact with
the skin. The brush having a heater embedded therein of the present
invention may be referred to as a heater embedded brush.
BACKGROUND ART
[0002] Generally, a hair brush is a kind of beauty appliance
suitable for arranging or grooming tangled hair, having a plurality
of soft bristles or elastic bristles alternately on one side of a
body having a handle. A comb is also used for grooming hair.
However, the comb teeth are arranged in a straight line and
sometimes it is not suitable for straightening long and tangled
hair. A comb is more suitable for straightening short hair than
long and tangled hair.
[0003] Most of the hair brushes suitable for brushing the soiled,
long and tangled hair are in the form of a round bar having a
predetermined length and thickness, and the tip of the round bar is
formed as a rounded head so as to provide a massaging effect
without damaging the scalp.
[0004] Both hair brushes and combs have many inconveniences with
wet hair or curly hair. As a method of grooming such hair, there
has been used a method of grooming the hair using a hot article
such as a hair dryer. However, in this case, the hair dryer should
be used with one hand and the comb or brush with the other hand.
Since both hands should be used, it is not easy to get a desired
shape at a desired area of the hair.
[0005] In recent years, there have been many cases where the hair
is groomed by using a hair styling apparatus provided with a
plate-type heat plate on the inner surface of the ends of a pair of
hinged knobs. Although, these hair styling apparatus have a great
effect on hair care, but if not an expert, it is possible to damage
the hair severely due to the heated heat plate and to easily burn
the finger or scalp. Even an expert cannot easily style on the back
of his/her head and needs a lot of time and effort to care for
hair, especially in case of long and thick hair.
[0006] When the hair is treated with hair brush, hair and dandruff
may be attached to the brush and the brush may become a habitat of
bacteria or ticks. When a brush is shared by members of the family,
if there is a patient having a scalp disease in the family, the
bacterium of the patient's scalp or microbial ticks can easily
spread to other people within the family.
[0007] In addition, in the case of a pet such as a dog or a cat, a
bad odor is caused by various bacteria and ticks in the skin of a
pet. To solve this problem, there is an increasing demand for an
antibacterial brush.

DESCRIPTION OF EMBODIMENTS
[0033] Hereinafter, a brush having a heater embedded therein
according to some embodiments of the present invention will be
described with reference to the accompanying drawings.
[0034] FIG. 1 is a block diagram of a brush having a heater
embedded therein according to an embodiment of the present
invention, FIG. 2 is an exploded perspective view of the brush
having heater embedded therein in FIG. 1, and FIGS. 3 to 5 are
perspective views of parts of the brush having heater embedded
therein in FIG. 1
[0035] Referring to FIG. 1, the brush having a heater embedded
therein includes a body 110, a guard 130, a heater 150, and a heat
radiator 170.
[0036] Hereinafter, the above elements will be described in
detail.
[0037] The body 110 includes a power input 111, an alarm 113, and a
cover 115.
[0038] The power input 111 receives power from the outside power
source and supplies power to the heater 150 so that the heater 150
can operate.
[0039] The alarm 113 may be configured by an LED or the like and
may display whether the power is connected, the power is on or off,
and the heater reaches to a temperature suitable for hair care.
[0040] The cover 115 blocks the heat generated by the heater 150
and prevents a safety accident such as burn during the use of the
brush.
[0041] The guard 130 includes a guard comb 131 and a guard base 133
to which the guard comb 131 is fastened. The guard comb 131 is in
the form of a plurality of round bars having a predetermined length
and thickness and formed around the edge of the guard of the
brush.
[0042] The guard base 133 serves to fix the guard comb 131 and to
block heat generated from the heater 150. For this purpose, the
guard base 133 is desirably formed of heat resistant plastic
materials such as polysulfone (PSU), polyethersulfone (PES),
polyetherimide (PEI), polyetheretherketone (PEEK) and
polyphthalamide, or is formed of a material having a low heat
transfer coefficient and excellent heat resistances such as
polycarbonate (PC), nylon resin, or the like.
[0043] The tips of the round bars of the guard comb 131 may be
formed to have a spherical head so as to provide a massage effect
while preventing damage to the skin when the hair is brushed. It
may also be formed of a heat resistant plastic material such as
polysulfone (PSU), polyethersulfone (PES), polyetherimide (PEI),
polyetheretherketone (PEEK) and polyphthalamide.
[0044] In another embodiment of the present invention, the guard
comb 131 may be formed of an elastic heat resistant plastic
material such as polycarbonate (PC), polyamide or the like. By
using an elastic material, it is possible to prevent breakage of
the guard comb 131 during use of the brush. Particularly, nylon 6
and nylon 66 are widely used in the case of nylon resin, which is
an aliphatic polyamide polymer. Nylon resin has excellent
mechanical properties, excellent friction and wear characteristics
compared to other engineering plastics, and both self-lubricating
and self-extinguishing properties. Nylon resin has excellent
composite effect by reinforcing agent such as glass fiber, carbon
fiber and the like or a filler, which is excellent in application
to the guard comb of the present invention.
[0045] Further, in another embodiment of the present invention, the
guard comb 131 may be formed of metal to prevent the possibility of
breakage.
[0046] The spacing among a plurality of round bars formed as the
guard combs is preferably 3-6 mm. If the spacing is smaller than
that, it is difficult to care for tangled hair. If the spacing is
larger than that, the possibility of a safety accident may increase
since the user may touch the radiator 170 with hands.
[0047] Although the guard 130 and the body 110 are shown as
separate parts in the figures, they may be formed as a single
integrated part.
[0048] A heater 150 may be formed in a space between the body 110
and the heat radiator 170. The heater 150 may be a PTC (Positive
Temperature Coefficient Resistance) heater having its own
temperature control capability to prevent overheating. Since the
PTC heater does not generate heat beyond a certain temperature, a
separate temperature control device such as a bimetal is not
required, and thus the brush can be made compact and
lightweight.
[0049] The heat radiator 170 includes a plurality of heat radiating
bristles 171 formed of a metal having an excellent thermal
conductivity and a heat radiating base 173 for fixing the heat
radiating bristles thereto.
[0050] The heat radiating bristles 171 and the heat radiating base
173 are preferably made of a metal so that the heat generated by
the heater 150 can be efficiently transferred thereto.
[0051] It is preferable that the length of the heat radiating
bristles 171 is shorter than the length of the guard comb 151 by 1
to 2 mm so that the heat radiating bristles 171 do not directly
contact the skin. The structure of the heat radiator 170 will be
described in detail below.
[0052] The heat radiating base 173 may be formed to include a
platinum (Pt) catalyst for antibacterial and deodorization. The
heat generated from the heater 150 is transferred to the platinum
catalyst, so that the antibacterial action can be performed. That
is, the heat generated in the heater 150 heats the platinum
catalyst layer, and the platinum catalyst is activated so that the
antibacterial function can proceed. After forming a metal oxide
layer on the heat radiating base 173, a plurality of nano holes are
formed in the metal oxide layer to form a platinum catalyst on the
surface of the nano hole. When contaminated air including bacteria
inflows into the nano holes, the decomposition reaction proceeds by
the platinum catalyst formed on the surface of the nano holes.
[0053] FIGS. 6A and 6B are views for explaining fastening types of
heat radiator, where heat radiating bristles 171 are fastened to
the heat radiating base 173 by rivet in FIG. 6A and by tight fit in
FIG. 6B.
[0054] A rivet is a kind of fastening parts. It is inserted into a
hole and its head is hammered to change its form to fix itself.
According to the embodiment of FIG. 6A, after the heat radiating
bristle 171 is inserted into the hole of the heat radiating base
173, a force F is applied to a portion of the rivet protruding on
the opposite side of the heat radiating bristle 171, and the heat
radiating bristle 171 can be fastened to the heat radiating base
173. Further, instead of forming the rivet head at the protruding
portion on the opposite side of the heat radiating base 173, the
rivet may be fastened to the heat radiating base 173 by welding or
soldering.
[0055] Referring to FIG. 6B, an insertion hole corresponding to the
fastening portion of the heat radiating bristle 171 is formed in
the radiating base 173. The insertion hole of the radiating base
173 is tight fitted with the fastening portion of the heat
radiating bristle 171 and thus heat radiating base 173 and the heat
radiating bristle 171 may be coupled to each other. As a structure
for implementing a tight fit, the diameter of the fastening portion
of the heat radiating bristle 171 is changed to have an oblique
shape, but the shape is not limited thereto. Using the tight fit
structure, the fastening structure can be simplified, the
manufacturing process can be simplified, and even if heat is
applied, the heat radiating base and the heat radiating bristles
can come into contact with each other and expand or contract
simultaneously and thus the possibility of decoupling is
blocked.
[0056] FIG. 7 is a view for explaining the tip of the heat
radiating bristle 171 fastened to the heat radiating base 173.
[0057] Referring to FIG. 7, the tip may be formed to have a
spherical head to reduce irritation to the skin during use of the
brush. The spherical head can be formed by covering the heat
radiating bristle made of a metal having a high heat transfer
coefficient with a cap made of a heat resistant plastic having a
low heat transfer coefficient.
[0058] FIG. 8 is a flowchart for explaining a manufacturing process
of a brush having a heater embedded therein according to an
embodiment of the present invention.
[0059] The manufacturing process according to the embodiment of the
present invention comprises the steps of: fabricating a body and a
guard by injection molding, fabricating a heat radiator, fixing a
heater to a space between the body and the guard, and assembling
the body, the guard and the heat radiator.
[0060] Referring to FIG. 8, the step of fabricating the heat
radiator during the manufacturing process comprises the steps of:
fabricating a heat radiating base S810, fabricating heat radiating
bristles S820, and fastening the heat radiating bristles to the
heat radiating base S830.
[0061] In step S810, insertion holes for fixing the heat radiating
bristles to the heat radiating base 173 are formed at predetermined
constant intervals. The insertion hole may be formed in a
through-hole shape passing through the heat radiating base.
[0062] In step S810, after the steps of coating a metal oxide layer
on the heat radiating base 173 and forming nano holes, a step of
forming a platinum catalyst on the nano holes may be further
performed.
[0063] In step S820, heat radiating bristles for inserting into the
insertion holes are prepared. Each heat radiating bristle can be
manufactured by any one of die casting and metal insert
injection.
[0064] Metal insert injection is a type of insert injection
molding, which is an injection molding method that integrates
plastic parts of heterogeneous, unusual colored or non-plastic such
as metal, electric wire, magnet, etc. in a mold. This method can
obtain a molded article having characteristics that are difficult
to obtain by plastic alone, and its application field is becoming
more and more widespread. Metal and plastic integrated products are
the majorities of metal insert injection articles, since it is
possible to make high value added product by combining the
rigidity, conductivity, surface treatment property of the metal and
insulating, coloring, flexibility, rigidity and workability of
plastic while reducing the time and cost of the manufacturing
process. In this embodiment, by covering the surface of the metal
which can be used as the heat radiating bristle with a plastic
material, it is possible to prevent excessive heat from being
directly transferred to the skin, and there is an advantage that a
separate plastic cap assembling process is unnecessary. However,
the heat transfer efficiency may be somewhat lowered.
[0065] Die casting is a casting method in which molten metal is
injected into a precisely machined steel die to exactly match the
required casting shape to obtain the same casting as the die. Since
the dimensions are accurate, there is little need for finishing
treatment. Excellent mechanical properties and mass production are
available and thus it is being applied in a wide range of fields.
In the present embodiment, it is easy to make a structure capable
of adding a plastic cap to the tip of the heat radiating bristle
when the heat radiating bristles are manufactured by the die
casting process. The portion of the brush that comes into contact
with the hair is formed of a metal having excellent thermal
conductivity, and the efficiency of the heat transfer to the hair
is also excellent.
[0066] In the step S830, the step of fastening the heat radiating
bristles to the heat radiating base may be performed by the tight
fit method or the rivet/welding method as described with reference
to FIG. 6A and FIG. 6B.
[0067] While the present invention has been described in connection
with what is presently considered to be practical exemplary
embodiments, it is to be understood that the invention is not
limited to the disclosed embodiments, but, on the contrary, It will
be understood by those skilled in the art that various changes in
the form and details may be made therein without departing from the
scope of the present invention. Although specific terms have been
employed herein, they are used for purposes of describing the
invention only to those of ordinary skill in the art and are not
used to limit the scope of the invention as defined in the
claims.
