Electric puffs
Abstract
Disclosed herein is an electric puff, intended to rapidly and
easily apply various types of cosmetics to a desired body part. A
conventional puff is problematic in that a user must dab a surface
covered with a cosmetic on a desired body part by hand, so that it
is very complicated to do a user's makeup, and besides, it is
difficult to keep a user's force constant, so that the cosmetic may
not be evenly applied to the desired body part. The electric puff
of this invention is constructed so that an actuating shaft is
swingably coupled to an electric motor installed in a handle-shaped
casing via a drive gear and a conversion gear and a puff head is
coupled to an upper end of the actuating shaft, thus allowing a
cosmetic to be evenly applied to a desired body part with a
constant force although a user does not reciprocate the puff by
hand, therefore allowing the user to rapidly and easily put on
makeup, and allowing the cosmetic to be effectively applied to the
desired body part.

Description
BACKGROUND OF THE INVENTION
[0001] 1. Field of the Invention
[0002] The present invention relates generally to electric puffs,
intended to rapidly and easily apply various types of cosmetics,
including powder, gel, facial cream, etc., to a desired body part,
especially the face, and more particularly, to an electric puff
which is constructed so that a rotating shaft of an electric motor
installed in a casing is coupled to an actuating shaft connected to
a puff plate, via a conversion means, thus oscillating the puff
plate forward and backward when the electric motor is driven.
[0003] 2. Description of the Related Art
[0004] As well known to people, a user applies a cosmetic to a
desired body part, especially the face, with the user's hand or
various kinds of makeup tools, such as a brush, a pencil, a puff,
etc. Particularly, when a user evenly applies makeup powder,
including foundation, to a desired body part, a small plate-shaped
puff is usually used.
[0005] The puff has a shape of a circular or rectangular plate
corresponding to a cosmetic casing so that the puff is easily
housed in the cosmetic casing. Generally, a finger strap is
provided on a surface of the puff to allow a user to easily hold
the puff.
[0006] Thus, when using the puff, the user's fingers are inserted
between the finger strap and the surface of the puff to hold the
puff. Thereafter, a cosmetic is put on the other surface of the
puff, and the user lightly dabs the puff on a desired body part
with a proper force. At this time, the cosmetic is removed from the
puff and applied to a desired body part.
[0007] The conventional puff is problematic in that a user must dab
a surface covered with a cosmetic on a desired body part by hand,
so that it is very complicated to do a user's makeup. Further,
since it is difficult to keep a user's force constant, the cosmetic
may not be evenly applied to the desired body part.
SUMMARY OF THE INVENTION
[0008] Accordingly, the present invention has been made keeping in
mind the above problems occurring in the prior art, and an object
of the present invention is to provide an electric puff, intended
to evenly and rapidly apply a cosmetic to a desired body part with
a constant force, although a user does not reciprocate the puff by
hand.

casing has a handle shape to allow a user to easily grip the
casing, and a puff head with a puff plate is coupled to a rotating
shaft of an electric motor installed in the casing to oscillate
forward and backward. Hereinafter, embodiments of the present
invention will be described in detail with reference to the
attached drawings.
[0017] FIG. 1 is a perspective view of the first embodiment of the
present invention, FIG. 2 is an exploded perspective view of the
first embodiment of the present invention, and FIGS. 3a and 3b are
vertical sectional views of the first embodiment of the present
invention.
[0018] The present invention provides an electric puff 1, intended
to apply a cosmetic to a desired body part with a constant
force.
[0019] The electric puff 1 includes a casing 10, which has a pair
of front parts 11a and 11b and a rear part 12 and has a handle
shape to allow a user to easily grip the casing 10. A motor seat 13
is provided at a middle portion in the casing 10. Further, a
support bracket seat 14 and a battery seat 15 are provided above
and under the motor seat 13, respectively. A pair of pin holding
pieces 16 is provided at an upper end in the casing 10.
[0020] An electric motor 20 is installed in the motor seat 13 of
the casing 10.
[0021] A battery 30 is installed in the battery seat 15 of the
casing 10 to supply electricity to the electric motor 20.
[0022] A drive gear 40 is coupled to a rotating shaft 21 of the
electric motor 20.
[0023] The electric puff 1 also includes a conversion gear 50.
[0024] The conversion gear 50 engages with the drive gear 40 to
change a rotating axis of the drive gear 40 at an angle of
90.degree. with respect to the drive gear 40. A cam shaft 51 is
provided on an inner surface of the conversion gear 50 to be
coupled to an actuating shaft 70. The conversion gear 50 is
supported on a support bracket 80 to be rotated by a rotary pin 52
provided at a center thereof.
[0025] The actuating shaft 70 has at a lower end thereof a
longitudinal hole 71 in which the cam shaft 51 of the conversion
gear 50 is inserted. A pair of support pins 72 is provided on both
sides on an outer circumference of the actuating shaft 70 to be
held by the pin holding pieces 16 of the casing 10. The actuating
shaft 70 is swung on the support pins 72 by the conversion gear
50.
[0026] The support bracket 80 is installed in the support bracket
seat 14 of the casing 10 to support the conversion gear 50.
[0027] Further, the electric puff 1 includes a puff head 90. The
puff head 90 includes a head part 92 and a connection pipe 93. To a
front surface of the head part 92 is attached a puff plate 91. The
connection pipe 93 is provided at a lower portion of the head part
92 to be detachably connected to the actuating shaft 70.
[0028] The reference numeral 60 denotes a spacer, and the reference
numeral 100 denotes a power switch.
[0029] In the first embodiment constructed as described above, a
user couples the puff head 90 to an upper end of the actuating
shaft 70 which projects out of the top of the casing 10. Next, the
user grips the casing 10 with one hand, and holds the puff plate 91
of the puff head 90 covered with a cosmetic, near a desired body
part, especially the face. In such a state, when the electric motor
20 is operated by the power switch 100, the puff plate 91
reciprocates forward and backward, and touches the desired body
part with a predetermined force, thus allowing the user to easily
put on makeup.
[0030] When electricity is applied to the electric motor 20 to
rotate the rotating shaft 21 and the drive gear 40, a rotating
force of the drive gear 40 is transmitted to the conversion gear
50. Thus, the cam shaft 51 rotates along with the conversion gear
50. At this time, the actuating shaft 70 coupled to the cam shaft
51 through the longitudinal hole 71 swings while being supported by
the support pins 72 provided at a predetermined position of the
actuating shaft 70, so that the puff head 90 coupled to the upper
end of the actuating shaft 70 reciprocates forward and backward,
thus allowing the cosmetic covered on the puff plate 91 of the puff
head 90 to be easily applied to the desired body part.
[0031] According to the first embodiment of the present invention,
the puff head 90 is easily replaced with another one, thus allowing
a different puff head to be used according to the kind of cosmetic,
for example, powder, facial cream, gel, etc.
[0032] FIGS. 4 and 5 show the second embodiment of the present
invention.
[0033] A puff plate 91 is attached to a head part 92 of a puff head
90 with a connection pipe 93.
[0034] An actuating shaft 70 is detachably coupled to the
connection pipe 93, and is swung while being supported by support
pins 72.
[0035] A groove 102 is provided at a lower end of the actuating
shaft 70.
[0036] Further, an eccentric unit is provided between the groove
102 and a rotating shaft 21, and is eccentrically rotated by an
electric motor 20 to change the rotating movement of the rotating
shaft 21 into the linear movement of the actuating shaft 70, thus
oscillating the puff plate 91 forward and backward.
[0037] The eccentric unit includes a shaft support part 103 to
support the rotating shaft 21 of the electric motor 20, and an
eccentric shaft 104.
[0038] The eccentric shaft 104 is provided on the shaft support
part 103 and eccentrically rotated by a drive force of the electric
motor 20 transmitted to the shaft support part 103 while moving
along the groove 102, thus causing the actuating shaft 70 to be
linear moved.
[0039] The elements of the second embodiment common to those of the
first embodiment will not be described herein.
[0040] The electric puff of the second embodiment is assembled as
follows. That is, the electric motor 20 having the rotating shaft
21 to be installed in a casing is provided, and the actuating shaft
70 is coupled to the rotating shaft 21 through the eccentric
unit.
[0041] In this case, since the eccentric unit includes the shaft
support part 103 and the eccentric shaft 104, the shaft support
part 103 is coupled to the rotating shaft 21 of the electric motor
20, and the eccentric shaft 104 is coupled to the groove 102
provided at the lower end of the actuating shaft 70.
[0042] Next, the support pins 72 of the actuating shaft 70 are
placed at predetermined positions so that the actuating shaft 70 is
swung while being supported by the support pins 72. An upper end of
the actuating shaft 70 is inserted into the connection pipe 93
provided on the puff head 90.
[0043] Subsequently, the puff plate 91 is attached to the head part
92 of the puff head 90. The power switch 100 is provided on an
outer surface of a rear part 12 of the casing to drive the electric
motor 20.
[0044] Finally, the rear part 12 is assembled with a plurality of
front parts 11a and 11b to form the casing. The front part 11a is
fastened to the rear part 12 by means of a locking pin 101.
[0045] In use of the electric puff constructed as described above,
the user grips the casing comprising the front parts 11a and 11b
and the rear part 12 and having the handle shape to allow the user
to easily grip, and holds the puff plate 91 attached to the head
part 92 near a desired body part. Thereafter, the power switch 100
provided on the rear part 12 is turned on.
[0046] When the power switch 100 is turned on, electricity is
supplied from the battery 30 to the electric motor 20 provided in
the casing comprising the front parts 11a and 11b and the rear part
12.
[0047] Thus, the electric motor 20 is driven by the electricity
supplied from the battery 30, and simultaneously, the rotating
shaft 21 coupled to the electric motor 20 is rotated.
[0048] Further, the shaft support part 103 of the eccentric unit
coupled to the rotating shaft 21 rotates along with the rotating
shaft 21, so that the eccentric shaft 104 provided on the shaft
support part 103 eccentrically rotates about the rotating shaft
21.
[0049] At this time, the eccentric shaft 104 eccentrically rotates
while moving the groove 102.
[0050] The actuating shaft 70, supported at a predetermined
position thereof by the support pins 72, is swung by the eccentric
rotation of the eccentric shaft 104. Thereby, the puff head 90
coupled to the upper end of the actuating shaft 70 through the
connection pipe 93 and the puff plate 91 attached to the head part
92 oscillate forward and backward by the actuating shaft 70.
[0051] Thus, a cosmetic put on the puff plate 91 is easily applied
to a desired body part by the horizontal reciprocating motion of
the puff plate 91.
[0052] According to the second embodiment of this invention, the
connection pipe 93 integrated with the puff head 90 is detachably
coupled to the upper end of the actuating shaft 70 in order to
easily replace the puff head 90 with another one.
[0053] Thus, a different puff head can be used according to the
kind of cosmetic, for example powder, facial cream, gel, and
others.
[0054] Although the preferred embodiments of the present invention
have been disclosed for illustrative purposes, those skilled in the
art will appreciate that various modifications, additions and
substitutions are possible, without departing from the scope and
spirit of the invention as disclosed in the accompanying
claims.
[0055] As described above, the present invention provides an
electric puff, which is constructed so that an actuating shaft is
swingably coupled to an electric motor installed in a handle-shaped
casing via a drive gear and a conversion gear and a puff head is
coupled to an upper end of the actuating shaft, or a rotating shaft
of the electric motor installed in the casing is coupled to the
actuating shaft connected to a puff plate, via an eccentric unit,
thus allowing a cosmetic to be evenly applied to a desired body
part with a constant force although a user does not reciprocate the
puff by hand, therefore allowing the user to rapidly and easily put
on makeup, and allowing the cosmetic to be effectively applied to
the desired body part.
