The present disclosure relates to a beauty device with rollers.
Unless expressly indicated otherwise, the contents explained in this section do not refer to any related art against the claims of the present application to be described below. In addition, it is not admitted that any art described in this section implies that the art is related to the present disclosure.
As human aging progresses, the muscles of the human face loose elasticity, causing wrinkles to be generated or the skin's sagging to occur. According to development of the beauty industry, devices for skin care have been developed so as to prevent wrinkles and sagging of the skin (in particular, the face) visible to the naked eye.
By way of example, there are beauty devices that can increase generation of collagen and elastic fibers through electric stimulus and reproduce skin cells, and in addition, make the skin healthy and elastic due to stimulating cell reproduction and increased blood flow, thereby enabling skin protection and care.
According to the related art, a ball-shaped rotating body is rotatably coupled to a handpiece and an electric stimulus generator is formed inside the handpiece, so as to transmit the electric stimulus to the rotating body.
However, the related art has been problematic in that an axis is warped while the rotating body is rotated for massaging, causing low frequency delivery to be discontinued or low frequency intensity to vary, and the related art has defects such that the massaging effect cannot be obtained as pulling of the skin is too excessive or skin stimulation is too minimal in the process of rolling the rotating body in a state that the rotating body comes into contact with the skin.
Accordingly, the present disclosure has been made keeping in mind the above problems occurring in the related art, and an objective of the present disclosure is to provide a beauty device with rollers, in which a pair of rotating body units coupled to form a predetermined angle therebetween are in no contact with a shaft part and rotate around the shaft part as a central axis, the skin is massaged as the rotating body units rotate and the skin is rolled and entered between roller parts if the roller parts come into close contact with the skin and are rolled, and simultaneously, if low frequency is applied from a main body unit to the rotating body unit, the roller part transmits the low frequency to the skin, thereby enabling the cosmetic effect to be maximized.
It should be understood that the scope of the present disclosure shall not be limited to the technical problems described above, and it is obvious that another technical problem may be derived from the description of the present disclosure to be described below.
In order to achieve the objective of the present disclosure, the present disclosure provides a beauty device with rollers. The beauty device includes a main body part held by a user in his/her hand, a pair of rotating body support parts, each of which has one end coupled to the main body part, the rotating body support parts having an angle (θ1) therebetween in a V-shape, and a pair of rotating body units coupled to the pair of rotating body support parts respectively, the rotating body units being configured to be rotated to massage the skin, and each of the rotating body units may include a shaft part provided with a step extended in diameter, the shaft part having an inclined side on which a tapered surface is formed, a first bearing part formed in close contact with the step, and inserted into the shaft part, a second bearing part inserted into the shaft part, being spaced apart from the first bearing part at a predetermined interval, a roller part rotatably coupled to each of the rotating body support parts, and having an insertion recess into which a part of the shaft part is inserted and being in close contact with an outer circumferential surface of the second bearing part, thereby rotating around the shaft part, and a nut part having a thorough hole inside, thereby allowing an inner circumferential surface thereof to be rotatably coupled to an outer circumferential surface of the first bearing part and allowing an outer circumferential surface thereof to be rotatably coupled to an inner circumferential surface of the roller part.
The shaft part has at an outside thereof a first ring groove in which the first bearing part is arranged, and each of the rotating body units may further include a first snap ring part inserted into the second bearing part at the first ring groove, the first snap ring part being larger than an outer diameter of the shaft part and being cut at one side thereof, thereby being in close contact with the first bearing part.
The shaft part has at an outside thereof a second ring groove in which the second bearing part is arranged, and each of the rotating body units may further include a second snap ring part inserted into the first bearing part at the second ring groove, the second snap ring part being larger than an outer diameter of the shaft part and being cut at one side thereof, thereby being in close contact with the second bearing part.
The roller part and the nut part may be screw-coupled to each other.
Each of the rotating body units may further include a packing part having an elastic component, the packing part being in contact with the nut part, and coming into close contact with the insertion recess of the roller part, and a ring-type ring support part inserted into the packing part, thereby fixing the packing part.
The roller part includes a support groove larger than an outer diameter of the packing part, and each of the rotating body units may further include a fixed support part inserted into the support groove, the fixed support part having one side which is open, being configured to prevent decoupling of the first bearing part, the nut part, the packing part, and the ring support part.
Each of the rotating body units may further include a spring part having one side in contact with the insertion recess of the roller part and an opposite side in contact with both a tapered one side of the shaft part and the second bearing part, thereby delivering electrons and wavelength to the roller part and elastically supporting the second bearing part.
An angle θ1 between the pair of rotating body support parts is in a range of 55° to 90°.
The pair of rotating body support parts are formed inclinedly toward a front of the main body part, and an angle θ2 between a front surface of the main body part and the rotating body support parts is in a range of 110° to 180°.
A distance () between the pair of roller parts is in a range of 5 to 7.9 mm.
The present disclosure is advantageous in that as a roller part is supported and rotated by two bearings, the skin is massaged as the roller part rotates, preventing low frequency delivery from being discontinued or low frequency intensity from varying due to sagging of the axis, which enables stable rotation of the roller part and stable delivery of the low frequency at uniform intensity to the skin.
The packing part comes into close contact with the insertion recess of the roller part to support the nut part, thereby preventing water or foreign matter from being introduced toward the nut part and the first bearing part.
The fixed support part is coupled by insertion to the support groove of the roller part, thereby preventing decoupling of the first bearing part, the nut part, the packing part, and the ring support part.
The spring part is configured to have the shaft part and the roller part communicate with each other, preventing abrasion of the shaft part due to direct contact with the insertion recess of the roller part, or occurrence of poor electricity transmission occurring due to poor connection or defects such as low frequency disturbance, etc., thereby allowing electrons or wavelength to be effectively transmitted to the roller part.
An angle and a distance between a plurality of roller parts are optimized, thereby greatly improving a massaging effect with less pain.
Assembling of the rotating body unit is simple, thereby producing an effect of improving productivity.

Conventionally, there have been problems such that the axis is warped, causing discontinuation of low frequency delivery or change in low frequency intensity, etc. However, in the beauty device with rollers according to the present disclosure, as a roller part 3040 is supported and rotated by two bearings, axial shaking is prevented, thereby enabling stable rotation of the roller part 3040. In addition, the axial shaking is prevented and resistance due to change in contact regions of the roller part 3040 and the spring part 3110 is minimized, enabling low frequency at uniform intensity to be delivered to the skin stably. The roller part 3040 and the spring part 3110 are in circular linear contact with each other, producing an effect that change in friction and resistance between the stationary spring part 3110 and the rotating roller part 3040 can be minimized. The packing part 3080 is in close contact with the insertion recess 3041 of the roller part to support the nut part 3050, serving to prevent water or foreign matter from being introduced toward the nut part 3050 and the first bearing part 3020. The fixed support part 3020 is coupled by insertion to the support groove 3042 of the roller part 3040, serving to prevent decoupling of the first bearing part 3020, the nut part 3050, the packing part 3080, and the ring support part 3090. The spring part 3110 is configured to have the shaft part 3010 and the roller part 3040 communicate with each other, thereby preventing the shaft part 3010 from being abraded due to direct contact with the insertion recess 3041 of the roller part 3040 or poor electricity transmission occurring due to connection failure or defects such as low frequency disturbance, etc., which enables electrons or wavelength to be effectively transmitted to the roller part 3040. An angle and a distance between a plurality of roller parts 3040 are optimized, serving to greatly improve a massaging effect with less pain. Assembling of the rotating body unit is simple, producing an effect of improving productivity.
