(12) As illustrated in FIG. 2, a facial massage device according to an exemplary embodiment of the present invention includes a mask 200 and a plurality of vibration modules 100 and configurations and operations of elements thereof will be described with reference to FIG. 2.

(13) The mask 200 forms an accommodation space for the vibration modules 100 such that the vibration modules 100 are accommodated in the accommodation space of the mask 200 and provide massage function to human face during vibration. At least one vibration module 100 may be provided and has own power supply to be driven independently. Due to this, the facial massage device drives the vibration modules 100 of the mask 200 without an external power supply to provide various massage functions and massages a specific portion of human face or the other portion excluding the specific portion.

(14) The facial massage device according to the exemplary embodiment of the present invention will be described with reference to FIGS. 2 to 8.

(15) Referring to FIGS. 2 to 4, the facial massage device includes a first mask 210, a second mask 220, and vibration modules 100. The facial massage device may further include a wearing unit 300.

(16) The first mask 210 and the second mask 220 are fixed by the circumstance of the mask to form the accommodation space therein. At least one of the first mask 210 and the second mask 220 has insertion holes allowing the vibration modules 100 to be inserted or withdrawn therethrough or insertion holes 210a through which insulators 180 of the vibration modules are withdrawn out. In this embodiment, the first mask 210 has the insertion holes 210a for withdraw of the insulators 180.

(17) The vibration modules 100 will be described with FIGS. 5 to 8. Referring to FIGS. 5 and 6, each of the vibration modules 100 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.

(18) 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 130, and the controller 140. The printed circuit board 110 may be a flexible printed circuit board (FPCB) for the purpose of allowing the vibration modules 100 being bent along contours of a user's face and closed attached thereto.

(19) The vibrator 120 is installed on the printed circuit board 110 and vibrates by receiving an electric power by the driver 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 100 directly performing facial massage but also a device transmitting power the facial massage to the whole vibration module 100. The vibrator 120 may be inserted into vibrator holes 160a formed in the printed circuit board 110 and the supporting plate 160.

(20) This is because of reduction of overall thickness of the vibration module of the facial massage device 100, and in other words, the overall thickness of the vibration module 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 100 so that the overall thickness of the vibration module 100 can be reduced.

(21) 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.

(22) 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 outputted or only a preset one type pulse is continuously outputted. 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.

(23) As illustrated in FIG. 7, FIGS. 7A to 7H are views showing massage operations of the vibrator which vibrates in different types according to output pulses outputted 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.

(24) FIG. 7A shows a case where relatively strong vibration continues same intensity for a preset time, FIG. 7B shows relatively strong vibration of same intensity repeated every preset short time interval, and FIG. 7C shows relatively strong vibration of same intensity repeated for a preset time every short time interval. Moreover, FIG. 7D shows visually weak vibration being gradually stronger for a preset time after starting and FIG. 7E shows strong vibration being gradually weakening for a preset time after starting contrary to the case of FIG. 7D. FIG. 7F shows early weak vibration is gradually stronger to the peak and is gradually weakened again.

(25) Return to FIGS. 5 and 6, 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 100 and its description is omitted because this is substantially identical to the insertion of the vibrator 120 into the vibrator holes 160a.

(26) 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 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.

(27) 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.

(28) 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.

(29) 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 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 100 and the electric power of the battery 150 may be spent only when the vibrator 120 is operated.

(30) 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.

(31) FIG. 8 is a rear side view of the vibration module of the facial massage device 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 100 (the rear side of the supporting plate) and may prevent direct contact between the vibrator 120 and human skin. In FIG. 8, 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 pas may be made in various types such as nonwoven fabric or a sheet containing liquid material.

(32) Referring to FIGS. 2 to 4 again, the wearing unit 300 puts the mask on a human head and is like a hair band in this embodiment, but the present invention is not limited thereto. The wearing limit 300 consists of a pair of bands, ends of which are fixed to lateral sides of the mask 200 and the other ends of which are provided with hook and loop fasteners 310 for connecting each other. Lengths of the hook and loop fasteners are relatively long such that length of the wearing unit 300 cab e adjusted by contact portions between the hook and loop fasteners 310.

(33) As described with reference to FIGS. 2 to 8, the facial massage device of the present invention can exhibit massage functions by driving a plurality of vibration modules 100 of the mask 200 which are independently driven by own power supply even without a separated external power supply. Moreover, since a plurality of vibration modules 100 massage a specific portion of human face or the other portion excluding the specific portion by user's choice, the facial massage device of the present invention can provide proper massage functions according to face skin conditions and personal tendency.

(34) In addition, since the drives of the vibration modules 100 are controlled in pulse width modulation (PWM) to drive the vibrators receiving power from the drives to be operated in various vibration patterns, the facial massage device of the present invention can provide various massage function such as appeasing, rubbing, picking, pressing, and knocking by controlling vibration patterns of the vibration modules.

(35) 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.
