In the exemplary embodiment of the present invention, the rotating member 165 is described as including the first driving pulley 162, the second driving pulley 163, and the belt member 164, but is not limited thereto. Although not shown in the drawings, the rotating member 165 is provided with a plurality of gears, and the rotational force of the driving motor 161 may be transmitted to the shaft member 180 by rotating the respective gears. In this case, the gear constituting the rotating member 165 may be provided with a material having a high strength such as plastic or metal, and thus may have excellent durability.

3 and 4, when the driving unit 160 receives a voltage from a battery (not shown), a rotation force may be generated in the driving motor 161. The rotational force of the driving motor 161 may be transmitted to the shaft member 180 through the rotating member 165 connected to one end of the driving motor 161.

One end of the shaft member 180 may be eccentrically rotated by the eccentric shaft 183. At this time, the eccentric shaft 183 is inserted into the through hole 192 of the connecting member 190, the eccentric shaft 183 is rotated by the drive motor 161 is driven in this state, the eccentric shaft 183 The inserted through hole 192 may convert the rotational motion into a linear reciprocating motion.

Here, the through hole 192 of the connector 191 may be provided in an oval shape, the long side of the ellipse is disposed in a direction perpendicular to the shaft 193, the short side of the ellipse is in a horizontal direction with the shaft 193 It can be arranged as. And, the long side of the through hole 192 may be provided with the same length as the width moved in the left and right directions when the eccentric shaft 183 is rotated.

As the through-hole 192 is provided in an elliptical manner, the through-hole 192 is provided in an elliptical shape so that the eccentric shaft 183 can be moved only left and right in the through-hole 192 when the eccentric shaft 183 is rotated. Can be reduced.

For example, when the through hole 192 is formed in another shape such as a circle rather than an ellipse, when the eccentric shaft 183 is rotated, the through hole 192 moves not only to the left and right but also to the top and bottom, so that the noise of moving the parts is greatly increased. Can be generated.

As shown in FIG. 3, when the shaft member 180 is rotated such that the eccentric shaft 183 is located at the bottom of the rotating plate 182, the eccentric shaft 183 is intermediate in the long axis direction of the through hole 192. It may be in a state inserted into the point, the connection member 190 is moved to the bottom so that the care unit 120 can be spaced far from the outer surface of the body portion (110). And, as shown in Figure 4, when the shaft member 180 is rotated so that the eccentric shaft 183 is located at the top of the rotating plate 182, the eccentric shaft 183 is the long axis direction of the through hole 192 In the intermediate point in the state, the connecting member 190 may be moved to the uppermost care unit 120 may be located adjacent to the outer surface of the body portion (110).

In addition, although not shown in the drawing, when the shaft member 180 is rotated so that the eccentric shaft 183 is located at the left or right side of the rotating plate 182, the eccentric shaft 183 is in the long axial direction of the through hole 192. In the left end or the right end may be inserted. This is because the connection member 190 is moved to the upper or lower, by rotating the eccentric shaft 183 through the through-hole 192 into which the eccentric shaft 183 is inserted, thereby converting the rotary motion into a vertical reciprocating linear movement. The care part 120 connected to the shaft 193 of the connection member 190 may be vertically moved. In this case, since the through hole 192 is provided in an elliptical shape, the eccentric shaft 183 may be moved from side to side in the through hole 192 as described above. The skin care device 100 according to the present invention may not reduce the tapping speed applied to the user's skin while dramatically reducing noise by employing a simpler structure of the driving unit 160.

In general skin care device, the rotational force of the driving motor is converted into linear motion or cam motion to apply stimulation to the skin. Therefore, noise is generated in the process of transmitting the power of the driving motor. There was a problem.

The present invention not only integrates the connector 191 and the shaft 193 so as to minimize noise in the miniaturized skin care device, and has a through hole 192 of the connector 191 in an elliptical shape, and has a through hole 192. By minimizing the diameter of the) can reduce the generation of noise in the body portion (110). In addition, by minimizing the outer diameter of the connector 191, by minimizing the contact portion with the body portion 110 can also reduce the friction noise.

Although the present invention has been described in detail through specific examples, it is intended to describe the present invention in detail, and the present invention is not limited thereto, and should be understood by those of ordinary skill in the art. It is obvious that the modifications and improvements are possible.

Simple modifications and variations of the present invention are all within the scope of the present invention, and the specific scope of protection of the present invention will be apparent from the appended claims.
