Description of the Related Art
[0002] Human's desire for beauty is not basic instinct, so desires for clean and beautiful
skin have made various efforts to manage skin and maintain youth along with human
history.
[0003] Even in this country, ancient biblical references and relics said that various efforts
for beauty have been made and recent desires for beauty are stronger such that interests
for cosmetic culture are stronger regardless of girls and boys.
[0004] In addition, as described above, skin is a very importance object in desires to be
a beauty and particularly face skin is one of importance factors determining a beautify
appearance and a factor of affecting looks deeply.
[0005] Thus, regardless of gender or ages, most people give efforts to protect and manage
their skin and various goods helpful to skin care are provided in order to satisfy
these efforts. For example, there are many good for the face skin care such as moisturizing
cosmetics, moisture cream for face, cosmetic mask, etc.
[0006] Among the cosmetics, women especially prefer patches among the cosmetics as one of
cosmetic tools because of features of maintaining wet face skin and making elastic
face skin. The patches are classified into portional patches and whole patches (usually
called as a cosmetic mask and a mask pack and hereinafter referred to as a "cosmetic
mask"), wherein the cosmetic masks are made in the form of coating liquid cosmetics
on a sheet covering face.
[0007] Moreover, in spite of simply applying cosmetics to skin or sticking the cosmetic
mask to face such that cosmetics are absorbed by face skin itself, provided are devices
to improve absorption of effective components of the cosmetic mask or cosmetics applied
to skin by applying a bit of physical stimulation or vibration to the skin.
[0008] FIG. 1 shows an existing device (hereinafter, referred to as a "skin stimulation
device") applying artificial stimulating to human face skin such that effective components
of the cosmetic mask or cosmetics are easily absorbed into the face skin, and as illustrated
in FIGS. 1 the existing skin stimulation device includes a patch 10, a skin contact
unit 20, and a vibrator 30.
[0009] The patch 10 is attached to a local portion of a face and the size and the number
thereof to be attached to the face are not limited.
[0010] The skin contact unit 20 is made of silicone-based material to be attached at least
to any portion of the area to which the patch 10 is not attached and has an adhesive
force due to silicon-based material.
[0011] The vibrator 30 includes a power supply 40 and a vibration generating unit 31, wherein
a silicon-based adhesive unit is attached to the lower side of the vibration generating
unit 31. The vibration generating unit 31 generates vibration using revolutions of
a motor, use the existing technology of generating vibration, and preferably has rotational
speed of 9,000 rpm to 15,000 rpm.
[0012] Operations of the existing skin stimulation device configured as described above
will be described. After the patch is attached to a desired portion of user's face
to which vibration is applied the skin contact unit is attached to the portion of
the user's face while the patch is placed at the lower side thereof. Then, a user
attaches the adhesive unit of the vibrator to a region of the skin contact unit on
which the patch is placed and an electric power is supplied to the vibrator such that
vibration is transmitted to the patch and the face skin. In this case, since the adhesive
unit and the skin contact unit of the vibrator are made of silicon-based material
to be attached to each other, the user's hands may be free from the vibrator.
[0013] However, the vibration generating unit and the power supply are connected to each
other by a preset length of wires in the existing skin stimulation device. Thus, since
the vibration generating unit cannot be operated independently, the skin stimulation
device should be equipped with the power supply and for this reason is big in size
and volume so that it is inconvenient to carry. Moreover, only a relatively small
vibration generating unit actually participates in applying stimulation to face skin
but the other most portions thereof do not associate with the stimulation. Thus, the
stimulation can be applied only to a relatively narrow region on the face skin near
the vibration generating unit and a large number of vibration generating units is
required to apply stimulation to a relatively wide area of the face skin.
[0014] In addition, the existing skin stimulation device has the power supply of a relatively
complex configuration and a relatively large volume because the existing skin stimulation
device includes a separated switch switching the power supply on/off and supplies
electric power to the vibrator by switching on/off of the switch. If the switch is
omitted for the purpose of preventing this problem, a power jack of the vibrator must
be separated from the power supply in order to stop the operation of the vibrator.
[0015] Furthermore, since the vibration generating unit is able to adjust intensity of the
skin stimulation according to RPM of the motor, the existing skin stimulation device
cannot provide various functions for skin massage.

Best mode for carrying out the invention
[0037] Hereinafter, a vibration module for skin massage according to an exemplary embodiment
of the present invention will be described in detail with reference to the accompanying
drawings.
[0038] FIG. 2 is a perspective view illustrating a vibration module for skin massage according
to an exemplary embodiment of the present invention. FIG. 3 is a side view illustrating
the vibration module for skin massage according to the exemplary embodiment of the
present invention.
[0039] As illustrated, a vibration module for skin massage 100 according to an exemplary
embodiment of the present invention includes a printed circuit board 110, a vibrator
120, a drive 130, a controller 140, a battery 150, a supporting plate 160, a power
connecting member 170, and an insulator 180.
[0040] The printed circuit board 110 is configured such that the vibrator 120 is installed
on a side thereof and the drive 130 and the controller 140 are mounted thereon. Thus,
the printed circuit board 110 has a circuit pattern for electrical connection between
the battery 150, the drive 120, and the controller 130. The printed circuit board
110 may be a flexible printed circuit board (FPCB) for the purpose of allowing the
vibration module 100 being bent along contours of a user's face and closed attached
thereto.
[0041] The vibrator 120 is installed on the printed circuit board 110 and vibrates by receiving
an electric power by the drive 130. The vibrator 120 is a device stimulating user's
skin with vibration therefrom. That is, the vibrator 120 is not only a device of the
vibration module for skin massage 100 directly performing skin massage but also a
device transmitting power for the skin massage to the whole vibration module for skin
massage 100. The vibrator 120 may be inserted into vibrator holes 160a formed in the
printed circuit board 110 and the supporting plate 160.
[0042] This is because of reduction of overall thickness of the vibration module for skin
massage 100, and in other words, the overall thickness of the vibration module for
skin massage 100, when the vibrator 120 is installed on a side of the printed circuit
board 110, becomes sum of the thickness of the vibrator 120 and the thicknesses of
the printed circuit board 110 and the supporting plate 160. Thus, the vibrator holes
160a are formed in the printed circuit board 110 and the supporting plate 160 and
the vibrator 120 is inserted into the vibrator holes 160a and the thicknesses of the
printed circuit board 110 and the supporting plate 160 is subtracted from the overall
thickness of the vibration module for skin massage 100 so that the overall thickness
of the vibration module for skin massage 100 can be reduced.
[0043] The drive 130 is mounted on the printed circuit board 110 and received electric power
from the battery 150 to supply the received electric power to the vibrator 120. The
drive 130 may be any one of a vibration motor, a solenoid, a piezo device, and a linear
vibrator.
[0044] The controller 140 is mounted on the printed circuit board 110 and controls the drive
130 to adjust vibration of the vibrator 120. The controller 140 controls the drive
130 in pulse width modulation (PWM). That is, the controller 140 operates the drive
130 in various modes through the PWM, while outputting at least two different pulses
wherein the different output pulses are sequentially output or only a preset one type
pulse is continuously output. The vibrator 120 may vibrate to provide various massage
functions such as appeasing, rubbing, picking, pressing, knocking, etc., according
to the various output pulses and the operating conditions of the drive 130.
[0045] As illustrated in FIG. 4, FIGS. 4A to 4I are views showing massage operations of
the vibrator which vibrates in different types according to output pulses output from
the controller 140 to the drive 130. That is, the colored portions in the drawings
are portions to which vibration of the vibrator is transmitted and the other portion
is portion where the vibrator is stopped or not attached.
[0046] FIG. 4A shows a case where relatively strong vibration continues same intensity for
a preset time, FIG. 4B shows relatively strong vibration of same intensity repeated
every preset short time interval, and FIG. 4C shows relatively strong vibration of
same intensity repeated for a preset time every short time interval. Moreover, FIG.
4D shows visually weak vibration being gradually stronger for a preset time after
starting and FIG. 4E shows strong vibration being gradually weakening for a preset
time after starting contrary to the case of FIG. 4D. FIG. 4F shows early weak vibration
is gradually stronger to the peak and is gradually weakened again. The description
for the rest drawings, FIGS. 4G to 4I is omitted.
[0047] Return to FIGS. 2 and 3, the battery 150 is installed on the supporting plate 160
and supplies electric power to the drive 130 and the controller 140 through the power
connecting member 170. The battery 150 may be inserted into a battery hole 160b formed
in the supporting plate 160 so as to reduce the overall thickness of the vibration
module for skin massage 100 and its description is omitted because this is substantially
identical to the insertion of the vibrator 120 into the vibrator holes 160a.
[0048] The supporting plate 160 is provided to connect the printed circuit board 110 to
the battery 150 integrally. The supporting plate 160 may be made of a flexible material
such that flexibility of the vibration module for skin massage 100 can be guaranteed.
Moreover, the supporting plate 160 may be configured such that the battery 150 and
the vibrator 120 are mounted at the ends in the major axis on an oval side of the
supporting plate 160, respectively. Thus, devices are not mounted at the middle portion
of the major axis and due to this the supporting plate 160 can exhibit elasticity
and higher flexibility.
[0049] The power connecting member 170 electrically connects the power terminals (not shown)
of the battery 150 to the power terminals (not shown) of the drive 130 on the printed
circuit board 110. In other words, the drive 130 receives electric power from the
battery 150 through the power connecting member 170. Moreover, the power terminals
of the printed circuit board 110 may supply electric power to the controller 140 and
in this case the printed circuit board 110 has circuit patterns connecting the power
terminals to the drive 130 and the controller 140 in parallel.
[0050] The insulator 180 is attached to a contact area between the power terminals of the
battery 150 and the power connecting member 170. That is, the insulator 180 is attached
to the battery 150 to interrupt the electrical connection between the power terminals
of the battery 150 and the power connecting member 170 and the electrical connection
between the power terminals of the battery 150 and the insulator 180 is made when
the insulator 180 is separated from the battery 150. The insulator 180 is detachably
attached to the battery 150 and controls the electrical connection between the power
terminals of the battery 150 and the power connection member 170 through the attachment
and detachment of the insulator 180 to control the electric power to be supplied from
the battery 150 to the drive 130 or not.
[0051] In other words, the insulator 180 can switch the electrical connection between the
power terminals of the battery 150 and the power connecting member 170 and in this
case the vibration module for skin massage 100 can spend the electric power of the
battery 150 only by the switching function of the insulator 180 even without a separated
switch. That is, omission of the switch allows reduction of volume of the vibration
module for skin massage 100 and the electric power of the battery 150 may be spent
only when the vibrator 120 is operated.
[0052] Although in this exemplary embodiment a thin sheet of the insulator 180 is detachably
attached to the battery 150 to screen the power terminals, the present invention is
not limited thereto but the insulator 180 may be attached to and detached from power
terminal regions of the battery 150 and may be modified under the conditions of applying
electric power between the power terminals of the battery 150 and the power connecting
member 170.
[0053] FIG. 5 is a rear side view of the vibration module for skin massage according to
the exemplary embodiment of the present invention in which the battery 150 and the
vibrator 120 are inserted into the battery hole 160b and the vibrator holes 160a that
are formed in the printed circuit board 110 and the supporting plate 160 and are fixed
thereto. A buffering pad (not shown) may be attached to the rear side of the vibration
module for skin massage 100 (the rear side of the supporting plate) and may prevent
direct contact between the vibrator 120 and human skin. In FIG. 5, the buffering pad
is omitted for the purpose of showing the battery hole 160b and the vibrator holes
160a and ones of sides of the battery 150 and the vibrator 120 which are inserted
thereinto. Moreover, the buffering pad may be made in various types such as nonwoven
fabric or a sheet containing liquid material.
[0054] As described with reference to FIGS. 2 to 5, the vibration module for skin massage
100 is configured such that the printed circuit board 110 on which the vibrator 120
and the drive 130 thereof and the controller 140 of the drive 130 are installed and
the battery 150 are integrally attached to the flexible supporting plate 160, so that
volume and thickness of the vibration module can be minimized and flexibility thereof
can be guaranteed and vibration of the vibrator 120 is transmitted to the human skin
through vibration of the whole vibration module so that the vibration can be transmitted
to a relatively wide area on the human skin in comparison to the size of the vibrator.
[0055] Moreover, the power supply of the drive 130 driving the vibrator 120 includes a switch
formed by thin terminals and a sheet insulator 180 so as to exclude a complex switch
having a manipulator such as buttons so that the simple configuration and minimum
volume thereof can be achieved and the electric power can be supplied to the drive
130 of the battery 150 by switching of an insulator 180 so that the electric power
of the battery is consumed only when the vibrator 120 is driven.
[0056] In addition, various vibrations of the vibrator 120 such as rubbing, picking, pressing,
and knocking similar to massage carried out by human hands, in addition to the simple
strong and weak vibrations, can be generated to improve skin massage effect by a controller
140 controlling the drive 130 of the vibrator 120 using pulse width modulation (PWM).
[0057] Furthermore, the vibration module for skin massage secures flexibility thereof to
be easily bent along the contour of user's face and to be closely attached to the
face resulting in improving transmission of vibration to the skin.
[0058] Furthermore, a vibration transmission region is relatively increased due to transmission
of vibration through whole the vibration module and overall volume thereof is relatively
reduced, resulting in improving mobility.
[0059] While this invention has been particularly shown and described with reference to
preferred embodiments thereof, these embodiments are provided so that this disclosure
will be thorough and complete, and will fully convey the concept of the invention
to those skilled in the art. It will be understood by those skilled in the art that
various changes in form and details may be made therein without departing from the
spirit and scope of the invention as defined by the appended claims.
