Description

Technical Field

[0001] The present invention relates to a skin treatment device with overheat protection, and more particularly, to a skin treatment device with overheat protection capable of simplifying the structure using a Peltier element and capable of safely cooling an overheated portion. Background Art

[0002] Generally speaking, there are many skin beauty devices that prevent skin aging by massaging the face.

[0003] A monopolar radio frequency (RF) device for improving skin elasticity uses the following principle: when radio frequency power is applied to two poles, heat is generated at the contact portion of the handpiece, one pole is formed on the handpiece in contact with the skin surface of the desired part, and the other pole is formed on a ground pad attached to the back or another part of the body, because there is body impedance between the two poles.

[0004] In the prior art, when high-frequency pulses with high energy are applied to generate heat that deforms skin cells, high heat may be generated on the epidermis of the skin that the handpiece contacts and may cause severe pain and burns. Therefore, a method of installing a small liquid nitrogen (LN2) tank in a device body is provided, the small LN2 tank is connected to the handpiece through a valve and a tube, and the LN2 is sprayed through a nozzle onto the back of a flexible printed circuit board (FPCB) constituting an electrode of the handpiece to cool the epidermis.

[0005] However, LN2 is a cryogenic liquid with a boiling point of -196°C. Therefore, a high-pressure safety container should be used to avoid frostbite during handling, while keeping LN2 in a liquid state in a small container. LN2 is a hazardous substance and requires strict attention when handling. Meanwhile, tubes and valves are used to connect and control the LN2 tank installed in the main body to the nozzle of the handpiece, but if these parts fail, an accident will occur. In addition, since the temperature of nitrogen gasified from LN2 is very low, it is necessary to spray nitrogen in a very short time in synchronization with the high-frequency pulse, but if the spray time becomes longer, moisture in the atmosphere will combine with nitrogen gas at the electrode part of the handpiece and condense immediately, and there is a risk of frostbite on the skin. Therefore, there is a problem in that it is difficult to optimally control the time and cycle of nitrogen spraying to appropriately adjust the cooling temperature of the skin surface within a range that can achieve a pain relief effect. Therefore, it is necessary to improve this.

[0006] The background of the present invention is disclosed in Korean Patent Publication No. 2014-0013643 (published on 02 / 05 / 2014, title: Skin Beauty Tool).

[0060] Figure 8 is a schematic diagram illustrating the flow of air through an air cooling unit according to one embodiment of the present invention. Figure 8 The skin treatment device 1 with overheat protection according to one embodiment of the present invention may further include an air cooling unit 60. The air cooling unit 60 may supply external air to the cooling unit 50 to forcibly cool the cooling unit 50.

[0061] More specifically, the air cooling unit 60 may include an air inflow portion 61 , an air discharge portion 62 , and an air outflow portion 63 .

[0062] The air inflow portion 61 may be formed in the grip unit 10 and guide the outside air to the inside of the grip unit 10. For example, the air inflow portion 61 may be formed at both sides of the grip housing portion 11 and form holes to guide the outside air to flow in. In addition, the air inflow portion 61 may have holes formed in one side or three or more parts of the grip housing portion 11, and the holes may be formed parallel to, inclined to, or perpendicular to the longitudinal direction of the grip housing portion 11. Meanwhile, the hole shape of the air inflow portion 61 may be elongated or circular, and holes of various other shapes may be formed.

[0063] The air discharge portion 62 may be built into the grip unit 10, and the air introduced through the air inflow portion 61 may be discharged to the cooling unit 50. For example, the air discharge portion 62 may be fixedly disposed inside the grip housing portion 11, connected to the power supply unit 20 or board, and used as a cooling fan that discharges air when power is applied. The air discharge portion 62 may be disposed behind the grip connection portion 12 and in front of the air inflow portion 61, and the air introduced into the air inflow portion 61 is supplied to the cooling unit 50 through the inside of the grip connection portion 12 through the air discharge portion 62.

[0064] The air outflow portion 63 may be formed in the assembly unit 30 and guide the air that has passed through the cooling unit 50 to the outside. For example, the air outflow portion 63 may be formed on a side surface portion of the assembly housing portion 31 and have one or more holes for air discharge. The air outflow portion 63 may guide the air to be discharged in a direction opposite to the surface of the skin to be treated (i.e., opposite to the direction in which the high-frequency pulses are emitted by the output unit 40).

[0065] The operation of the skin treatment device with overheat protection according to one embodiment of the present invention having the above-described structure will now be described.

[0066] The grip connection part 12 and the grip manipulation part 13 are mounted on the grip housing part 11, and the air discharge part 62 is mounted at the rear of the grip connection part 12. In addition, the output unit 40 and the cooling unit 50 are mounted on the assembly unit 30.

[0067] When the assembly unit 30 equipped with the output unit 40 and the cooling unit 50 is assembled to the grip housing portion 11 , the assembly unit 30 is locked and fixed to the grip manipulation portion 13 , and the output unit 40 and the cooling unit 50 are electrically connected to each other through the grip connection portion 12 .

[0068] When power is applied to the output unit 40 and the cooling unit 50 for skin treatment in the above state, the output unit 40 in contact with the skin outputs high-frequency pulses to treat the skin. In this case, the output unit 40 is heated, and the cooling unit 50 in contact with the output unit 40 can cool the output unit 40 using a Peltier element and discharge the heated air to the outside.

[0069] Meanwhile, when the air discharge portion 62 is driven, the air introduced through the air inlet portion 61 is discharged to the cooling unit 50 through the air discharge portion 62. The air discharged to the cooling unit 50 through the air discharge portion 62 passes between the cooling fins of the cooling heat exchanger portion 52 and is then discharged to the air outflow portion 63, thereby achieving rapid heat dissipation of the cooling unit 50 and improving the heat dissipation effect of the cooling unit 50.

[0070] According to a skin treatment device 1 with overheating protection according to one embodiment of the present invention, even if the output unit 40 is heated during the skin treatment process, the output unit 40 is quickly cooled by the cooling unit 50, thereby preventing skin damage due to overheating, and the assembly unit 30 equipped with the output unit 40 and the cooling unit 50 is attached to the holding unit 10 in a detachable manner, thereby enabling the assembly unit 30 to be easily replaced.
