BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a skin care device, and more particularly, to a skin care device that enables efficient cleaning by allowing an inner brush and an outer brush to rotate in opposite directions.

Generally, everyone has desire for beauty of body regardless of sex. In order to pursue the beauty of this body, especially the skin that others will first recognize, people use various means and methods to manage the skin.

Skin care aims to maintain clean, smooth skin without dirt, and is most interested in the management of facial skin among body parts. Therefore, people continue their efforts to keep their skin clean by using a facial skin care product, applying a functional cosmetic product that beautifully shows the skin, or using various cleaning products.

Among them, the importance of cleansing for removing wastes of the skin is gradually increasing. For the purpose of cleansing, people wash the cleansing products such as liquid cleansing products by applying them to the face.

However, when cleansing using a hand, the cleansing product may not be uniformly delivered to the skin, and bacterial infection may be caused by the hand. Recently, a method of indirectly applying a cleansing product to the skin . Particularly, a cleansing method using a device including a brush and causing vibration or rotation is widely popular among tools.

Conventionally, the brush device is a method in which the brush is rotated in one direction as a whole, or is cleaned in accordance with a user's movement using vibration, which transmits asymmetric force to a face having a symmetrical muscle arrangement. There is also a problem that the irritation to the skin can not be diversified. Particularly, in the case of a product rotated in one direction or a product operating with a strong vibration, the cleaning product may cause a problem of splashing to the outside, which may cause inconvenience to the user, and the cleaning product may enter a sensitive area such as the eyes and cause serious problems.

Or the other end of the inner brush 10 may be in the shape of an arrow having a larger cross section and a smaller cross section as shown in Fig. 6, or may be in a widened form as shown in Fig.

Of course, the inner brush 10 may be manufactured in various forms in order to efficiently perform the cleaning of the skin. In the present embodiment, the inner brush 10 is not limited to the above-described form.

The outer contact portion 20 is brought into close contact with the skin in the same manner as the inner contact portion 10 to clean or massage the skin. The outer contact portion 20 may be provided on the outer side of the inner brush 10 and may be an outer brush 20 having a plurality of teeth. Hereinafter, the outer contact portion 10 will be described as an outer brush 20 in the same manner as the inner contact portion 10, but the outer contact portion 10 is not limited to the outer brush 20, Shaped < / RTI > The outer brush 20 may be provided to surround the outer side of the inner brush 10. At this time, the number of the outer brushes 20 may be relatively smaller than the number of the inner brushes 10.

The outer brush 20 has the same or similar shape as the inner brush 10 and the description of the outer brush 20 is omitted in the description of the inner brush 10. However, the shape, size, shape, material, color, and the like of the inner brush 10 of the outer brush 20 need not always be the same, and the thickness and height of the inner brush 10 may be different from each other.

In order to allow the user to easily identify the inner brush 10, the outer brush 20 is rotated in a direction opposite to the outer direction of the inner brush 10, . ≪ / RTI >

The inner rotary part (30) rotates the inner brush (10). The inner rotary part 30 is rotated by receiving power through a driving source 50 to be described later and rotates the inner brush 10 as one end of the inner brush 10 rotates in a fixed state.

The inner rotating portion 30 may include an inner rotating plate 31, an inner rotating shaft 32, and an inner rotating body 33. The inner rotation plate 31 fixes the inner brush 10. For fixing the inner brush 10 to the inner rotary plate 31, various methods such as using an adhesive material or ultrasonic welding can be used.

The inner rotation plate 31 may be provided in a disc shape and the inner rotation axis 32 may be provided on the surface opposite to the surface where the inner brush 10 is provided. At this time, the inner rotary plate 31 and the inner rotary shaft 32 may be integrally formed or separately provided and assembled.

The inner rotation shaft 32 forms the rotation center of the inner rotation plate 31. The inner rotary shaft 32 may be provided at the center of the inner rotary plate 31. Of course, the inner rotary shaft 32 may be arranged to be shifted from the center of the inner rotary plate 31. In this case, the outer rotary portion 40 to be described later is formed by the inner rotary plate 31 rotating through the shifted inner rotary shaft 32 So that the inner rotating plate 31 can be prevented from colliding with the outer rotating plate 41.

The thickness of the inner rotary shaft 32 may be variously determined according to the weight of the inner rotary plate 31 or the rotational speed thereof and the inner rotary shaft 32 may be positioned inside the outer rotary shaft 42 to be described later. That is, when the inside of the outer rotary shaft 42 is empty, the inner rotary shaft 32 is provided to be rotatable inside the outer rotary shaft 42.

One end of the inner rotation shaft 32 may be fixed to the inner rotation plate 31 and the other end may be fixed to the inner rotation body 33. Of course, since the inner rotating body 33 can be directly fixed to one surface of the inner rotating plate 31, the inner rotating shaft 32 can be omitted.

The inner rotating body 33 is provided on the inner rotating shaft 32. The inner rotating body 33 may be an inner gear 33 on which a gear is formed, or may be an inner roller rotated using surface frictional force. Hereinafter, the case where the inner rotating body 33 is the inner gear 33 will be described for the sake of convenience only. Of course, the inner rotating body 33 of the present invention may have various forms other than the inner gear 33, such as a roller.

The inner gear 33 can be engaged with the power transmission portion 60 and rotated and the inner rotary plate 31 can be rotated through the inner rotary shaft 32 when the inner gear 33 rotates.

The outer rotary part (40) rotates the outer brush (20). The outer rotating part 40 may include an outer rotating plate 41, an outer rotating shaft 42 and an outer rotating body 43 in the same manner as or similar to the inner rotating part 30. The outer rotating plate 41 fixes the outer brush 20 and the outer brush 20 is fixed to the outer rotating plate 41 by the method of adhesion or fusing as described above.

The inner rotation plate 31 may have a disk shape, but the outer rotation plate 41 is provided to surround the inner rotation plate 31 and may have a ring shape instead of a disk shape. At this time, the inner hole of the ring may be equal to the diameter of the inner rotary plate 31 or may be larger by a certain margin.

When the inner rotary shaft 32 is connected to a position deviated from the center of the inner rotary plate 31, the inner hole of the outer rotary plate 41 is sufficiently large enough that the inner rotary plate 31 rotated by the inner rotary shaft 32 does not collide with the inner rotary shaft 31 Can be largely formed.

The outer rotation plate 41 may have a ring shape and one surface on which the outer brush 20 is fixed may be placed on the same plane as the inner surface of the inner rotation plate 31 on which the inner brush 10 is fixed. Of course, the present embodiment includes a case where one surface of the outer rotary plate 41 and one surface of the inner rotary plate 31 are arranged to be shifted from each other.

However, one surface of the outer rotary plate 41 and one surface of the inner rotary plate 31 may be parallel to each other, even if one surface of the outer rotary plate 41 and the inner rotary plate 31 are arranged to be shifted from each other.

However, since the inner rotation shaft 32 and / or the outer rotation shaft 42 include a universal joint, rotation of the inner rotation plate 31 and / or the outer rotation plate 41 is realized, The plane formed by one surface of the outer rotary plate 41 and the plane formed by one surface of the inner rotary plate 31 may intersect with each other.

The outer rotation shaft 42 forms a rotation center of the outer rotation plate 41. At this time, the outer rotary shaft 42 may be formed in a hollow shape so that the inner rotary shaft 32 may be provided therein. Therefore, the outer rotary shaft 42 has a diameter sufficiently larger than the inner rotary shaft 32.

In this embodiment, the outer rotary shaft 42 is formed in a hollow shape and the inner rotary shaft 32 is provided inside the outer rotary shaft 42. At this time, the outer rotary shaft 42 and the inner rotary shaft 32 are moved in opposite directions And may further include a bearing 70 for holding the outer rotation shaft 42 and the inner rotation shaft 32 and implementing rotation in the opposite direction.

At this time, the bearing 70 may be a roller bearing, a ball bearing, or the like. In addition, various types of bearings 70 may be used. In addition, lubricating oil is supplied to the bearing 70 so that friction between the inner rotary shaft 32 and the outer rotary shaft 42 during relative rotation can be reduced.

The outer rotating body 43 is provided on the outer rotating shaft 42 to rotate the outer rotating plate 41. The outer rotating body 43 may be an outer gear 43 or an outer roller in the same manner as the inner rotating body 33. The outer rotating body 43 will be described below as an outer gear 43 for the sake of convenience.

The inner gear 33 rotates in engagement with the driving rotary body 61 of the power transmission portion 60 while the outer gear 43 rotates in engagement with the reverse rotary body 62 of the power transmission portion 60 have. Accordingly, the present embodiment can implement the opposite rotation of the inner brush 10 and the outer brush 20.

The drive source (50) generates power to be transmitted to the inner rotary part (30) and the outer rotary part (40). The driving source 50 may be a rotary motor or a servo motor for rotating the inner brush 10 and the outer brush 20 at a predetermined angle.

The driving source 50 includes a driving shaft 51 and is driven to receive power from a battery (not shown) and rotate the driving shaft 51. The power transmission unit 60 is connected to the drive shaft 51 so that the power transmission unit 60 receives the rotational force from the drive shaft 51 and can transmit the rotational force to the inner rotation unit 30 and the outer rotation unit 40,

The drive rotation body 61 rotates in engagement with the internal gear 33 or a reverse rotation body 62 to be described later and may be a drive gear 61 or a drive roller. Hereinafter, a case in which the drive rotator 61 is a drive gear 61 having gears will be described as an example. The drive gear 61 may be a general pinion gear, or it may be a worm gear in this embodiment. Therefore, the drive shaft 51 of the drive gear 61 and the inner rotary shaft 32 and the outer rotary shaft 42 can be arranged to be shifted from each other.

The power transmission portion 60 transmits the power of the driving source 50 to the inner rotation portion 30 and the outer rotation portion 40 in opposite directions to each other. According to the present embodiment, the power transmitting portion 60 can transmit the power of the driving source 50 directly to the inner rotating portion 30, and can transmit the power to the outer rotating portion 40 by switching the direction.

The power transmission portion 60 may include a drive gear 61 and an inversion rotor 62. The driving gear 61 is provided on the driving shaft 51 of the driving source 50 and can be rotated by the rotation of the driving shaft 51. At this time, the driving gear 61 is engaged with the inner gear 33 so that the rotational force of the driving shaft 51 can be transmitted to the inner rotating plate 31 through the driving gear 61 and the inner gear 33.

The reversing gear 62 may be a reversing gear 62 or an inverting roller and the reversing gear 62 may be a driving gear 61 and an outer gear 62 43 to switch the rotation direction of the drive shaft 51 and transmit the rotation to the outer gear 43. Since the inner gear 33 is directly connected to the driving gear 61, when the driving shaft 51 rotates in the clockwise direction, the inner gear 33 is rotated counterclockwise Since the drive shaft 61 and the rotary shafts 32 and 42 are arranged to be shifted from each other when the drive gear 61 is a worm gear, the rotation direction of the internal gear 33 is not accurately seen in the counterclockwise direction. The same applies to the rotating direction of the outer gear 33).

Since the outer gear 43 is connected to the drive gear 61 via the reversing gear 62 so that when the drive shaft 51 rotates in the clockwise direction, the gear is engaged two times, . Thus, the outer gear 43 and the inner gear 33 can rotate in opposite directions, and the inner brush 10 and the outer brush 20 are rotated in the opposite direction.

The reversing gear 62 may include a first reversing gear 621, a second reversing gear 622, and a reversing shaft 623. This is because the position for engaging the drive gear 61 and the position for engaging the outer gear 43 are distant from each other.

The first reverse gear 621 is engaged with the drive gear 61 and the second reverse gear 622 is engaged with the outer gear 43. [ At this time, the first reverse gear 621 and the second reverse gear 622 are fixed to the reverse shaft 623 and can be integrally rotated.

However, since the reversing gear 62 may be provided with a gear having a long length, one reversing gear 62 may be provided to directly transmit the rotational force of the driving gear 61 to the outside gear 43.

The rotational speeds of the inner gear 33 and the outer gear 43 may be changed depending on the diameter of the reversing gear 62 or the ratio of the gear ratio. In other words, the inner brush 10 and the outer brush 20 can be rotated in opposite directions to each other and rotated at different speeds. Of course, the rotational speeds of the inner brush 10 and the outer brush 20 can be variously determined by adjusting the diameters or gears of the inner gear 33, the outer gear 43, and the like.

The present embodiment may include a case 80 covering the above-described configurations, and the case 80 may expose the inner brush 10 and the outer brush 20 to the outside. At this time, the case 80 is made of plastic or the like, forms a friction surface on the outside, and is provided in the form of dumbbells or the like, so that the case 80 can be easily grasped by a user. That is, the user can perform cleaning by bringing the inner brush 10 and the outer brush 20 into close contact with the skin while holding the case 80.

Thus, in this embodiment, the inner gear 33 is engaged with the drive gear 61 of the worm gear type, and the outer gear 43 is held by the drive gear 61 through the reverse gear 62, The inner brush 10 rotated by the inner gear 33 and the outer brush 20 rotated by the outer gear 43 are rotated in opposite directions to each other to provide sufficient stimulation required for cleaning the skin And it is possible to prevent the cleaning product from protruding to the outside by the centrifugal force generated when the inner brush 10 rotates by the outer brush 20, thereby preventing waste of the cleaning product.

Since the configuration except for the power transmission portion 60 in this embodiment is the same as or similar to the configuration in the first embodiment described above, a description of the configuration other than the power transmission portion 60 will be omitted.

The driving gear 61 of the power transmitting portion 60 provided in the driving shaft 51 in the present embodiment is constituted by a plurality of driving gears 61 having different diameters or gears and the plurality of driving gears 61 All of which are fixed to the drive shaft 51 and can be rotated at one time.

At this time, one of the driving gears 61 is engaged with the inner gear 33, and the other one of the driving gears 61 is engaged with the reversing gear 62. In this case, since the gears of the two drive gears 61 are different from each other, the rotation ratios are different. Therefore, in the present embodiment, the rotation direction and / or the rotation speed of the inner brush 10 and the outer brush 20 can be formed differently.

Of course, the rotation speed can be variously determined depending on the gear ratio of the internal gear 33, the reverse gear 62, and the external gear 43, in addition to the gear difference of the drive gear 61. However, in the present embodiment, it is assumed that the ratios of the gears other than the drive gear 61 are all the same, the gears of the drive gears 61 having different gears are different from each other by the difference between the inner brush 10 and the outer brush 20 ) May occur.

As described above, in the present embodiment, a plurality of driving gears 61 are provided, and the plurality of driving gears 61 have gear teeth different from each other, so that the rotational speed of the inner brush 10 and the outer brush 20, It is possible to increase the cleaning power.

The pinion gear 63 is capable of rotating and revolving, which can be realized by a carrier (not shown) connecting a plurality of pinion gears 63. The carrier is a frame that connects the pinion gear 63 and transmits a rotational force to each of the pinion gears 63 (to implement the rotation of the pinion gear 63) or a plurality of pinion gears 63 63).

The pinion gear 63 can be rotated so that the inner gear 33 and the outer gear 43 are rotated in opposite directions. At this time, the pinion gear 63 is rotated in place without revolving, and the inner gear 33 and the outer gear 43 rotate in opposite directions to each other.

On the other hand, the pinion gear 63 can rotate so that the inner gear 33 and the outer gear 43 are rotated in the same direction.

The elastic member 35 may be a spring, and a plurality of elastic members 35 may be provided on the entire surface of the inner rotary plate 31 to provide a stable elastic force.

The inner brush 10 or the outer brush 20 is subjected to the elastic force so that the inner brush 10 and / or the outer brush 20 are brought into close contact with the skin, and excessive pressure is applied to the skin It is possible to maximize the satisfaction of the user.

11 and 12 are views showing a brush of a skin care device according to a fifth embodiment of the present invention.

11 and 12, the inner brush 10 of the skin care device 1 according to the fifth embodiment of the present invention can be inclined with respect to the outer brush 20 provided in the outer rotation part 40 have. The configurations other than the rotating parts 30 and 40 and the brushes 10 and 20 may be the same as or similar to those described in the first to fourth embodiments.

The motions of the inner brushes 10 can be arranged obliquely with the wings of the outer brushes 20 to achieve intensive cleaning. 11, the inner brush 10 may be provided perpendicular to the inner rotary plate 31 and the outer brush 20 may be inclined in the vertical direction of the outer rotary plate 41 .

The inner brush 10 may be inclined in the vertical direction of the inner rotary plate 31 and the outer brush 20 may be provided perpendicular to the outer rotary plate 41. [

The inner brush 10 and the outer brush 20 may be inclined with respect to the vertical direction of the inner rotary plate 31 and the vertical direction of the outer rotary plate 41, respectively, as shown in FIG.

The other end of the outer brush 20 opposite to the one end connected to the outer rotation part 40 may be inclined in a direction adjacent to the inner brush 10 and conversely the inner brush 10 may be inclined with respect to the inner rotation part The other end of the one end connected to the outer brush 20 may be biased in a direction adjacent to the outer brush 20.

Accordingly, the inner brush 10 may extend outward with respect to the center of the inner rotation part 30, and the outer brush 20 may be formed to converge inward with respect to the center of the inner rotation part 30 .

As described above, according to the present embodiment, since the outer brush 20 has a form in which it is gathered inward, intensive cleaning can be realized, the cleaning force can be improved, and the usage amount of the cleaning product can be saved.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the same is by way of illustration and example only and is not to be construed as limiting the present invention. It is obvious that the modification and the modification are possible.
