(en)BACKGROUND OF THE INVENTION
1. Field of the Invention
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.
2. Description of the Related Art
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.
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.
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.
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
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.

Hereinafter, embodiments of the present invention will be described in detail with reference to the attached drawings.
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. 3 a and 3 b are vertical sectional views of the first embodiment of the present invention.
The present invention provides an electric puff 1 , intended to apply a cosmetic to a desired body part with a constant force.
The electric puff 1 includes a casing 10 , which has a pair of front parts 11 a and 11 b 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 .
An electric motor 20 is installed in the motor seat 13 of the casing 10 .
A battery 30 is installed in the battery seat 15 of the casing 10 to supply electricity to the electric motor 20 .
A drive gear 40 is coupled to a rotating shaft 21 of the electric motor 20 .
The electric puff 1 also includes a conversion gear 50 .
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° 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.
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 .
The support bracket 80 is installed in the support bracket seat 14 of the casing 10 to support the conversion gear 50 .
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 .
The reference numeral 60 denotes a spacer, and the reference numeral 100 denotes a power switch.
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.
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.
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.
FIGS. 4 and 5 show the second embodiment of the present invention.
A puff plate 91 is attached to a head part 92 of a puff head 90 with a connection pipe 93 .
An actuating shaft 70 is detachably coupled to the connection pipe 93 , and is swung while being supported by support pins 72 .
A groove 102 is provided at a lower end of the actuating shaft 70 .
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.
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 .
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.
The elements of the second embodiment common to those of the first embodiment will not be described herein.
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.
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 .
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 .
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 .
Finally, the rear part 12 is assembled with a plurality of front parts 11 a and 11 b to form the casing. The front part 11 a is fastened to the rear part 12 by means of a locking pin 101 .
In use of the electric puff constructed as described above, the user grips the casing comprising the front parts 11 a and 11 b 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.
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 11 a and 11 b and the rear part 12 .
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.
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 .
At this time, the eccentric shaft 104 eccentrically rotates while moving the groove 102 .
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 .
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 .
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.
Thus, a different puff head can be used according to the kind of cosmetic, for example powder, facial cream, gel, and others.
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.
