Description

[Technical field]

[0001] The present invention relates to a high frequency skin cosmetic device, and more particularly to a high frequency skin cosmetic device capable of preventing skin burns after skin treatment using high frequency waves. [Background technology]

[0002] Human skin is made up of the epidermis, dermis, and subcutaneous fat layers. The epidermis prevents bacteria from entering and blocks moisture from escaping from the body, while the dermis contains fibrous proteins and matrix such as collagen and elastin, and provides nutrients to the epidermis. The subcutaneous fat layer is located below the dermis and absorbs pressure and shocks from the outside and maintains body temperature.

[0003] As the skin ages, it gradually loses elasticity and wrinkles appear. This is generally due to a decrease in the amounts of collagen, elastin and matrix within the dermis layer, as well as a decrease in water content.

[0004] To improve fine lines, pores, aging, scars, etc., high frequency skin cosmetic treatment is used, in which electrodes that transmit electrical energy are inserted into the dermis layer and high frequency energy is applied directly. High frequency skin cosmetic treatment uses thin needles as electrodes to apply electrical energy with a certain frequency directly to the human body, and the electrical energy is converted into thermal energy where the needles come into contact with the skin, and the converted thermal energy stimulates the regeneration of collagen and elastin, which are skin growth factors.

[0005] However, conventional high-frequency skin cosmetic methods have the problem that heat is generated in the needles used in the electrodes, which generates heat in the skin around the needles, causing aftereffects such as the treated area turning red or causing mild burns to the skin after treatment.

[0006] The background art of the present invention is disclosed in Patent Document 1 (issued on March 19, 2012) entitled "Skin Treatment Device Using High Frequency." [Prior art documents] [Patent documents]

[0007] [Patent Document 1] Korean Patent No. 10-1124675 Summary of the Invention [Problem to be solved by the invention]

[0016] In the present invention, the heat generating portion is made of a conductor and can convert the current flowing due to the alternating magnetic field into heat by eddy current loss and hysteresis loss.

[0017] In the present invention, the heat generated from the heat generating part is not transferred to the circular rod part, but is transferred as thermal energy to the dermis layer part in contact with the heat generating part, thereby treating the skin.

[0018] In the present invention, the needles of the needle assembly may have the same length. Effect of the Invention

[0028] 1 and 2, a high frequency skin cosmetic device according to an embodiment of the present invention includes a high frequency generator 120, a coil unit 130, a moving unit 140, a needle assembly 150, and a controller 160. Here, the high frequency generator 120 may be provided in a main body (not shown) of the high frequency skin cosmetic device, and the coil unit 130, the moving unit 140, and the needle assembly 150 may be provided in a handpiece case 110 shown in FIG.

[0029] The handpiece case 110 also serves as a handle that the user can grip, and can provide an internal space. The handpiece case 110 has a substantially cylindrical shape, and can have an internal space in which the coil unit 130, the needle assembly 150, and the moving unit 140 are installed. The handpiece case 110 can be made of an insulating material such as plastic.

[0030] The front end of the handpiece case 110 may be the portion of the handpiece case 110 that comes into contact with the skin.

[0031] The high frequency generating unit 120 is supplied with power and can output a high frequency current.

[0032] The high frequency generating unit 120 may include an inverter unit (not shown) that converts a DC power source into an AC power of 100 kHz to 10 MHz so as to generate an induced electromotive force. Specifically, the high frequency generating unit 120 may include an input filter circuit (not shown), a primary rectifier circuit (not shown), a power factor correction circuit (not shown), a switching circuit (not shown), an insulating transformer (not shown), a secondary rectifier circuit (not shown), an inverter circuit (not shown), and an output common filter (not shown). The input filter circuit blocks noise from the input AC power supply, the primary rectifier circuit and the power factor correction circuit improve the power factor while setting the input voltage range to 85 to 264V, the switching circuit switches the DC power supply input from the power factor correction circuit and transmits it to the isolation transformer as AC, the isolation transformer insulates the primary side from the secondary side while adjusting the output voltage, the secondary rectifier circuit rectifies the AC power supply input from the isolation transformer to DC, the inverter circuit adjusts the frequency transmitted to the coil unit 130, and the output common filter removes common mode noise contained in the output power supply before transmitting it to the coil unit 130.

[0033] The high frequency generating unit 120 is connected to the (+) and (-) poles of the coil unit 130, and may receive power and transmit it to the coil unit 130. The high frequency generating unit 120 may pass a high frequency current through the coil unit 130.

[0034] The coil unit 130 can convert the high frequency current output from the high frequency generating unit 120 into an alternating magnetic field. That is, the coil unit 130 can convert the alternating current input from the high frequency generating unit 120 into an alternating magnetic field having energy. For example, the coil unit 130 can convert the alternating current of 100 kHz to 10 MHz transmitted from the high frequency generating unit 120 into an alternating magnetic field via the coil 134.

[0035] The coil section 130 may be disposed at the front end of the handpiece case 110 as shown in Fig. 3. That is, the coil section 130 may be disposed in a portion that comes into contact with the skin.

[0036] Such a coil unit 130 may include a coil 134, a substrate 132 on which the coil 134 is disposed, and a number of through holes 136, as shown in FIG.

[0037] The coil 134 may be arranged in a spiral shape on the substrate 132 .

[0038] The coil 134 may be located on the substrate 132 and positioned between the substrate 132 and the skin-contacting surface of the handpiece case 110. Maximum energy transfer is possible when the coil portion 130 is positioned closest to the skin.

[0039] One surface of the substrate 132 may be a contact surface that contacts the skin of the user during treatment, and the coil 134 may be disposed on the other surface of the substrate 132. A plurality of through holes 136 may be formed in the substrate 132. The substrate 132 may be a concept that includes a bobbin.

[0040] The substrate 132 is preferably made of a non-metallic material such as rubber, silicone, or plastic so as not to affect the high frequency current flowing through the coil 134 .

[0041] The plurality of through holes 136 are disposed on the substrate 132, and the plurality of needles 155 can pass between the coils 134. The plurality of through holes 136 may be formed in a lattice shape at predetermined intervals as shown in Fig. 5. In the present embodiment, the plurality of through holes 136 are formed in a lattice shape, but this is not necessarily limited thereto, and the through holes may be formed in various shapes over the entire front end portion of the case 110. The front end portion of the case 110 comes into contact with the user's skin.

[0042] When the needle assembly 150 is lowered while the contact surface in contact with the user's skin is pressed against the skin, the needle 155 of the needle assembly 150 passes downward through the through hole 136 and stimulates the dermis layer of the skin.

[0043] The diameter of the through hole 136 may be larger than the diameter of the needle 155 so that the needle 155 can be easily inserted into the through hole 136 .

[0044] By positioning the multiple needles 155 within the multiple through holes 136, the coil portion 130 can prevent the multiple needles 155 from bending just before the multiple needles 155 are inserted into the skin, and can improve the straightness of the multiple needles 155.

[0045] The moving part 140 is installed in the handpiece case 110 and can move the needle assembly 150 (vertically) to bring the needle assembly 150 into or out of contact with the skin.

[0046] The moving unit 140 can vertically raise and lower the multiple needles 155. The multiple needles 155 are fixed to the moving unit 140, and the multiple needles 155 are raised and lowered vertically by the movement of the moving unit 140. The multiple needles 155 can be inserted into the skin by protruding from one surface of the front end of the case 110 by the moving unit 140. The moving unit 140 may be configured to vertically raise and lower via a separate driving means (not shown) provided inside or outside the case 110. The driving means may be a motor and a ball screw, a pneumatic actuator, an electromagnetic device, or the like.

[0047] The needle assembly 150 may include a plurality of needles 155 that are heated by the alternating magnetic field generated by the coil portion 130 and contact the skin to provide skin treatment.

[0048] Each of the multiple needles 155 is designed to be inserted about 0.1 to 4 mm into the skin, and the alternating magnetic field generated by the coil unit 130 causes a current to flow in the heat generating unit 155b inserted into the skin. The heat generating unit 155b can convert the current generated at this time into heat due to eddy current loss and hysteresis loss.

[0049] The needles 155 of the needle assembly 150 may have the same length as one another. The diameter of each needle 155 may be in the micron range.

[0050] Such a needle 155 may include a circular rod portion 155a and a heat generating portion 155b as shown in Fig. 6. That is, the upper end of the needle 155 may be composed of the circular rod portion 155a that does not conduct electricity (has non-conductor properties) and has high thermal resistance, and the lower end may be composed of the heat generating portion 155b that is conductive and has low thermal resistance.

[0051] The circular rod portion 155a may be made of an insulator (non-conductor) and may be connected to the moving portion 140 at its upper end.

[0052] The heat generating portion 155b is connected to the circular rod portion 155a and can generate heat by the alternating magnetic field generated by the coil portion .

[0053] The heat generating portion 155b is made of a conductor, and when an alternating magnetic field causes a current to flow, the heat generating portion 155b can generate heat due to eddy current loss and hysteresis loss caused by the current. The heat generating portion 155b may be made of, for example, a metal material.

[0054] The alternating magnetic field can induce eddy currents in the heating part 155b made of a conductor. The eddy currents can be converted into heat in the heating part 155b through eddy current loss and hysteresis loss. Hysteresis loss refers to energy loss that occurs when the heating part 155b is demagnetized from magnetized by the alternating magnetic field. The heat generated from the heating part 155b can be transferred as thermal energy to the dermis layer portion in contact with the heating part 155b, rather than being transferred to the circular rod part 155a, which has a large thermal resistance. The skin can be treated by the heat transferred to the dermis layer of the skin.

[0055] When the needle assembly 150 is inserted into the skin, each needle 155 can be inserted about 0.1 to 4 mm from the epidermis. The heat generating unit 155b can be inserted into the dermis layer of the skin to treat the skin using heat. For example, when high frequency is applied to the needle assembly 150, a large number of thermal energy reaching areas A are distributed in the thickness direction of the dermis layer.

[0056] The controller 160 can control the high frequency generating unit 120 and the moving unit 140 .

[0057] The controller 160 may also be coupled to switches (not shown) arranged on the outer surface of the handpiece case 110. A user may operate the switches to generate control signals.

[0058] The operation of the high frequency skin cosmetic device 100 configured as above will now be described.

[0059] While holding the high frequency skin cosmetic device 100, the practitioner brings the contact surface of the front end of the handpiece case 110 into contact with the patient's skin. When the contact is complete, the practitioner can operate a switch (not shown) disposed on the case 110 to move the moving unit 140 down toward the skin. When the moving unit 140 moves down, the needle assembly 150 connected to the moving unit 140 also moves down, and the needle 155 passes through the epidermis layer and pierces the dermis layer as shown in FIG. 7. At the moment the needle 155 is inserted into the dermis layer, the high frequency generating unit 120 is operated to generate high frequency. The high frequency generating unit 120 transmits a high frequency current to the coil unit 130, and the coil unit 130 can convert the high frequency current output from the high frequency generating unit 120 into an alternating magnetic field.

[0060] In each of the multiple needles 155, an electric current flows through the heat generating portion 155b inserted into the skin due to the alternating magnetic field generated by the coil portion 130, and the heat generating portion 155b can convert the electric current into heat due to eddy current loss and hysteresis loss caused by the flowing current. That is, the heat generating portion 155b of each needle 155 is heated by the alternating magnetic field generated by the coil portion 130, and can output thermal energy as shown in A of Fig. 7. The thermal energy output from the heat generating portion 155b of each needle 155 can coagulate tissue inside the dermis layer and regenerate and activate collagen.

[0061] As described above, the high frequency skin cosmetic device according to one embodiment of the present invention has the effect of preventing skin burns or redness that may occur after treatment by not generating heat in the circular rod portion of the needle, but only in the heating portion at the tip of the needle.

[0062] In addition, the high frequency skin cosmetic device according to one embodiment of the present invention has the effect of promoting the regeneration of skin tissue and the skin cosmetic effect by transferring electrical energy into the inside of the skin as thermal energy using high frequency induction heat technology.
