Description

Technical Field

[0001] The present invention relates to a cooling system for a skin care device.

Background Art

[0002] Currently, skin care devices have been developed that cleanly manage the skin through procedures such as removing wrinkles, restoring skin elasticity, and removing sebum. This is because cleanly maintained skin makes people look younger and contributes to an attractive appearance.

[0003] Skin care devices include a type that transmits ultrasonic waves to the skin (HIFU type), a type that transmits high frequency to the skin (RF type), and a type that transmits laser light to the skin (Optical type).

[0004] Here, in the method of transmitting high frequency to the skin, the high frequency generated by the RF electrode is applied to a target region of the skin through the epidermis of the skin. As a result, coagulative necrosis is induced in the target region of the skin, so that aged collagen and elastic fibers in the target region of the skin are removed, and new collagen and elastic fibers can be formed. Coagulative necrosis of the target region of the skin is also effective in improving skin pigmentation, acne scars, wrinkles, and the like.

[0005] In addition, conventional skin care devices have had the problem that, when the high-frequency application process of the RF electrode continues, the temperature of the target region of the skin rises excessively, resulting in burns occurring in the target region of the skin.

[Modes for carrying out the invention]

[0026] The advantages and features of the present invention, and methods for achieving them, will become clear with reference to the embodiments described below in detail with the accompanying drawings. However, the present invention is not limited to the embodiments disclosed below and can be embodied in a variety of different forms. These embodiments are provided to complete the disclosure of the present invention and to allow a person ordinary in the art to fully understand the scope of the invention, and the present invention is defined only by the scope of the claims.

[0027] The terms used herein are for illustrative purposes only and are not intended to limit the invention. In this specification, singular terms include plural terms unless otherwise specified. The terms “comprises” and / or “comprising” as used in this specification do not preclude the presence or addition of one or more other components in addition to those mentioned.

[0028] Unless otherwise defined, all terms used herein (including technical and scientific terms) are used in the sense that they would be commonly understood by an ordinary person skilled in the art to which the present invention pertains. Furthermore, terms defined in commonly used dictionaries shall not be interpreted ideally or excessively unless explicitly defined otherwise.

[0029] Hereinafter, embodiments of the present invention will be described in detail with reference to the attached drawings.

[0030] Figure 1 is a perspective view showing a cooling system for a skin care device according to one embodiment of the present invention, Figure 2 is an exploded perspective view showing the storage container 10 and storage container loading section 60 of the cooling system for a skin care device according to one embodiment of the present invention, and Figure 3 is a front view showing the cooling system for a skin care device according to one embodiment of the present invention.

[0031] As shown in Figure 1, a cooling system for a skin care device according to one embodiment of the present invention includes a storage container 10, a chamber 20, a discharge valve 30, a fluid sensor 40, and a pressurizing unit 50.

[0032] The storage container 10 stores the cooling fluid. The cooling fluid stored in the storage container 10 can then be supplied to the chamber 20. Furthermore, the cooling fluid can be a cooling gas or a cooling liquid. For example, HFO (hydrofluoroolefin) may be used as the cooling gas, and water may be used as the cooling liquid.

[0033] As shown in Figure 2, the storage container 10 can be formed in a cylindrical shape overall. A storage container discharge section 11 for discharging the cooling fluid can be provided on one side of the storage container 10. Such a storage container discharge section 11 may have a shape in which the diameter decreases as it moves away from the storage container 10. On the other hand, the storage container 10 can be detachably connected to a storage container loading section 60, which will be described later. Therefore, when the cooling fluid stored in the storage container 10 is completely consumed, the storage container 10 can be removed from the storage container loading section 60, and a new storage container 10 can be connected to the storage container loading section 60. At this time, the new storage container 10 may be filled with cooling fluid.

[0034] Chamber 20 can be filled with cooling fluid transferred from storage container 10. The cooling fluid thus filling chamber 20 can be discharged to the outside through discharge valve 30. As an example, chamber 20 may be formed longitudinally as a whole.

[0035] As shown in Figure 3, the discharge valve 30 serves to discharge or shut off the cooling fluid filling the chamber 20. For example, the discharge valve 30 may be a mouse valve or a solenoid valve.

[0036] As an example, the discharge valve 30 can connect the chamber 20 to the skin care device. In this case, the cooling fluid discharged through the discharge valve 30 can be transmitted to the skin care device. As a result, the cooling fluid transmitted to the skin care device can prevent malfunctions of the skin care device due to temperature rise. Here, the discharge valve 30 can be connected to the skin care device via the coupler 160.

[0037] As another example, the discharge valve 30 can be connected to the chamber 20 on one side and positioned adjacent to the target area of ​​skin to which electrical energy is applied by the skin management device on the other side. In this case, the cooling fluid discharged through the discharge valve 30 can be applied to the target area of ​​skin to which electrical energy is applied by the skin management device. As a result, the cooling fluid applied to the target area of ​​skin to which electrical energy is applied by the skin management device can induce pain relief and sedation of the target area of ​​skin.

[0038] For example, the discharge valve 30 can be opened and closed by control of a control unit (not shown) to discharge or shut off the cooling fluid filling the chamber 20. Here, the control unit may be a microcontroller.

[0039] The fluid sensor 40 can measure the water level of the cooling fluid filling the chamber 20. For example, the fluid sensor 40 can measure the pressure at the lower end of the chamber 20 and the pressure at the upper end of the chamber 20, and calculate the water level in the chamber 20 by measuring the differential pressure between the pressure at the lower end of the chamber 20 and the pressure at the upper end of the chamber 20. Specifically, since the lower end of the chamber 20 is filled with cooling fluid and the upper end of the chamber 20 is filled with air from the atmosphere, the fluid sensor 40 can measure the pressure of the cooling fluid filling the lower end of the chamber 20 and the pressure of the air from the atmosphere filling the upper end of the chamber 20, and calculate the water level in the chamber 20 by measuring the differential pressure between the pressure of the cooling fluid in the chamber 20 and the pressure of the atmosphere. As another example, the fluid sensor 40 can be installed at a reference water level point between the lower end and the upper end of the chamber 20, and when the water level of the cooling fluid filling the chamber 20 exceeds the reference water level point of the chamber 20, it can sense that the amount of cooling fluid filling the chamber 20 has exceeded the fluid sensor 40.

[0040] On the other hand, if the water level measured by the fluid sensor 40 remains constant during the set time, the internal pressure of the storage container 10 may be less than or equal to the internal pressure of the chamber 20, which may prevent the cooling fluid stored in the storage container 10 from being transferred to the chamber 20. Therefore, it is necessary to increase the internal pressure of the storage container 10 to transfer the cooling fluid stored in the storage container 10 without leaving any in the chamber 20. For example, the set time may be between 10 and 30 seconds.

[0041] The pressurizing unit 50 can increase the internal pressure of the storage container 10 so that its internal pressure becomes greater than the internal pressure of the chamber 20 when the water level measured by the fluid sensor 40 remains constant for a set period of time. As a result, all of the cooling fluid stored in the storage container 10 can be transferred to the chamber 20.

[0042] The pressurizing section 50 may include a pressurizing heater 51, an insulating material 52, and a pressurizing temperature sensor (not shown).

[0043] The pressurizing heater 51 can heat the storage container 10 and increase the internal pressure of the storage container 10 when the water level measured by the fluid sensor 40 is maintained at a constant value. For example, the pressurizing heater 51 may have a shape that surrounds the storage container 10. Specifically, the pressurizing heater 51 may have an annular shape.

[0044] For example, the pressurizing heater 51 can adjust the temperature of the storage container 10 from room temperature to 50°C. For instance, room temperature can be between 1°C and 30°C, but the present invention is not limited to this.

[0045] The insulating material 52 surrounds the storage container 10 and the pressurizing heater 51, and plays a role in keeping the storage container 10 and the pressurizing heater 51 warm. Therefore, after the temperature of the storage container 10 increases due to heating by the pressurizing heater 51, the insulating material 52 can reduce the heat loss and pressure loss of the storage container 10.

[0046] The pressurizing temperature sensor can measure the internal temperature of the storage container 10. Such a pressurizing temperature sensor can transmit the measured internal temperature of the storage container 10 to the pressurizing heater 51. The pressurizing heater 51 can then heat the storage container 10 so that its internal temperature increases, based on the measured internal temperature of the storage container 10 transmitted from the pressurizing temperature sensor.

[0047] For example, when the cooling fluid filling the chamber 20 is discharged, if the water level measured by the fluid sensor 40 remains constant or rises, the cooling fluid stored in the storage container 10 may be transferred to the chamber 20. At this time, the control unit can determine that there is a sufficient amount of cooling fluid remaining in the storage container 10.

[0048] As another example, if the water level measured by the fluid sensor 40 decreases when the cooling fluid filling the chamber 20 is discharged, it may be because the amount of cooling fluid stored in the storage container 10 is small or nonexistent, and therefore the cooling fluid stored in the storage container 10 is not transferred to the chamber 20. In this case, the control unit can determine that the amount of cooling fluid remaining in the storage container 10 is insufficient and emit an alarm sound indicating that the remaining amount in the storage container 10 needs to be checked.

[0049] A cooling system for a skin care device according to one embodiment of the present invention may further include a storage container loading section 60, connecting piping 70, a check valve 80, a pressure maintenance section 90, a pressure sensor 100 for the storage container, and a pressure sensor 110 for the chamber.

[0050] The storage container loading section 60 can be used to load the storage container 10 in a separable manner. As shown in Figure 2, a storage container connecting section 61 may be formed on one side of the storage container loading section 60, which is inserted into the storage container discharge section 11 of the storage container 10. Such a storage container connecting section 61 has a smaller diameter than the storage container discharge section 11 and can be inserted into the storage container discharge section 11. On the other side of the storage container loading section 60, a piping connecting section may be formed to connect the insertion section of the storage container 10 to the connecting pipe 70.

[0051] The connecting pipe 70 serves to connect the storage container loading section 60 and the chamber 20.

[0052] The check valve 80 is installed in the connecting pipe 70 and plays a role in controlling the flow of cooling fluid in the connecting pipe 70 toward the chamber 20.

[0053] The pressure maintenance unit 90 is provided in the chamber 20 and plays the role of maintaining a constant internal pressure in the chamber 20. Therefore, even if the pressurizing unit 50 does not excessively increase the internal pressure of the chamber 20, the internal pressure of the storage container 10 becomes even greater than the internal pressure of the chamber 20, allowing the cooling fluid stored in the storage container 10 to be easily transferred to the chamber 20.

[0054] The pressure maintenance unit 90 may include a pressure maintenance heater 91 and a pressure maintenance temperature sensor.

[0055] The pressure-maintaining heater 91 can heat the chamber 20 at regular time intervals so that the internal pressure of the chamber 20 is maintained at a constant level. Specifically, the pressure-maintaining heater 91 can heat the chamber 20 at regular time intervals so that the internal temperature of the chamber 20 is maintained at a temperature higher than room temperature.

[0056] For example, the pressure-maintaining heater 91 can adjust the temperature of the chamber 20 from room temperature to 35°C. For example, room temperature is 1°C to 30°C, but the present invention is not limited to this.

[0057] A pressure-maintaining temperature sensor can measure the internal temperature of the chamber 20. Such a pressure-maintaining temperature sensor can transmit the measured internal temperature of the chamber 20 to a pressure-maintaining heater 91. The pressure-maintaining heater 91 can then heat the chamber 20 at regular time intervals to maintain a constant internal temperature of the chamber 20, based on the measured internal temperature of the storage container 10 transmitted from the pressure-maintaining temperature sensor.

[0058] The storage container pressure sensor 100 can measure the internal pressure of the storage container 10, and the chamber pressure sensor 110 can measure the internal pressure of the chamber 20. Here, the measured values ​​of the internal pressure of the storage container 10 measured by the storage container pressure sensor 100 and the measured values ​​of the internal pressure of the chamber 20 measured by the chamber pressure sensor 110 can be transmitted to the control unit. Subsequently, if the measured value of the internal pressure of the storage container 10 transmitted from the storage container pressure sensor 100 is the same as or less than the measured value of the internal pressure of the chamber 20 transmitted from the chamber pressure sensor 110, the control unit can control the pressurizing unit 50 to increase the internal pressure of the storage container 10.

[0059] A cooling system for a skin care device according to one embodiment of the present invention may further include a relief valve 120.

[0060] The relief valve 120 can be opened and closed by user operation to discharge or interrupt the cooling fluid filling the chamber 20 to the outside.

[0061] For example, the relief valve 120 can discharge the cooling fluid filling the chamber 20 to the outside via the relief piping 130. The relief piping 130 can be connected to the relief valve 120.

[0062] The following describes the operation process of a cooling system for a skin care device according to one embodiment of the present invention.

[0063] Figures 4 to 6 are front views showing the operation process of a cooling system for a skin care device according to one embodiment of the present invention. The following processes can be performed by the control unit.

[0064] First, the cooling fluid stored in the storage container 10 is transferred to the chamber 20. (See Figure 4)

[0065] Subsequently, the fluid sensor 40 measures the water level of the cooling fluid filling the chamber 20. At this time, if the water level of the cooling fluid filling the chamber 20, as measured by the fluid sensor 40, remains constant, it is possible that the cooling fluid stored in the storage container 10 is not transferred to the chamber 20 via the connecting pipe 70 and check valve 80. In this case, the pressurizing unit 50 increases the internal pressure of the storage container 10 so that its internal pressure becomes even greater than the internal pressure of the chamber 20. As a result, the cooling fluid stored in the storage container 10 can be transferred to the chamber 20 via the connecting pipe 70 and check valve 80 without any remaining fluid.

[0066] Next, the control unit opens the discharge valve 30, allowing the cooling fluid filling the chamber 20 to be discharged to the target object via the discharge valve 30. (See Figure 5)

[0067] At this time, when the cooling fluid filling the chamber 20 is discharged, if the water level measured by the fluid sensor 40 remains constant or rises, the cooling fluid stored in the storage container 10 may be transferred to the chamber 20. At this time, the control unit can determine that there is a sufficient amount of cooling fluid remaining in the storage container 10.

[0068] Furthermore, when the cooling fluid filling the chamber 20 is discharged, if the water level measured by the fluid sensor 40 decreases, it may be because the amount of cooling fluid stored in the storage container 10 is small or nonexistent, and therefore the cooling fluid stored in the storage container 10 is not transferred to the chamber 20. At this time, the control unit can determine that the amount of cooling fluid remaining in the storage container 10 is insufficient and emit an alarm sound indicating that the remaining amount in the storage container 10 needs to be checked.

[0069] Here, the relief valve 120 can be forcibly opened by user operation to discharge the cooling fluid filling the chamber 20 to the outside.

[0070] On the other hand, when moving the cooling system for the skin care device or when completely draining the cooling fluid filling the chamber 20 for repair, the cooling fluid filling the chamber 20 is completely drained via the relief valve 120, eliminating the need for the barb fitting section 150, described later, which prevents leakage between the relief valve 120 and the relief piping 130. Therefore, the relief valve 120 and the relief piping 130 can be easily separated and connected via the one-touch fitting section 140.

[0071] Figure 7 is a perspective view showing a one-touch fitting section 140 of a cooling system for a skin care device according to one embodiment of the present invention.

[0072] As shown in Figures 1 and 7, the cooling system for a skin care device according to one embodiment of the present invention may further include a one-touch fitting section 140.

[0073] The one-touch fitting section 140 can serve to detachably connect the relief valve 120 and the relief piping 130. Inside such a one-touch fitting section 140, a flow path can be formed that connects the relief valve 120 and the relief piping 130.

[0074] The one-touch fitting section 140 may include a one-touch fitting body 141, a one-touch fitting coupling section 142, and a one-touch fitting holder 143.

[0075] The one-touch fitting body 141 is the basic body of the one-touch fitting section 140 and serves to connect the one-touch fitting coupling section 142 and the one-touch fitting holder 143.

[0076] The one-touch fitting coupling portion 142 is provided on one side of the one-touch fitting body 141 and can be detachably coupled to the relief valve 120. For example, the one-touch fitting coupling portion 142 may be bolt-shaped and can be screwed onto the relief valve 120.

[0077] The one-touch fitting holder 143 is provided on the other side of the one-touch fitting body 141, and the relief piping 130 can be easily inserted in a detachable manner. Therefore, since the relief valve 120 and the relief piping 130 are easily connected by the one-touch fitting part 140, the time required for the worker to assemble and detach the relief valve 120 and the relief piping 130 can be reduced, thereby improving the worker's work efficiency.

[0078] For example, the one-touch fitting holder 143 may have a tubular shape.

[0079] Figure 8 is a perspective view showing the barb fitting section 150 of a cooling system for a skin care device according to one embodiment of the present invention.

[0080] As shown in Figure 8, the cooling system for a skin care device according to one embodiment of the present invention may further include a barb fitting section 150 and an auxiliary barb fitting section 150'.

[0081] The barb fitting section 150 can serve to connect the connecting pipe 70 and the chamber 20. A flow path can be formed inside such a barb fitting section 150 that connects the connecting pipe 70 and the chamber 20.

[0082] The barb fitting section 150 may include a barb fitting body 151, a barb fitting coupling section 152, and a barb fitting clamp 153.

[0083] The barb fitting body 151 is the basic body of the barb fitting section 150 and serves to connect the barb fitting coupling section 152 and the barb fitting clamp 153.

[0084] The barb fitting connector 152 is provided on one side of the barb fitting body 151 and can be detachably coupled to the chamber 20. For example, the barb fitting connector 152 may be bolt-shaped and can be screwed into the chamber 20.

[0085] The barb fitting clamp 153 is provided on the other side of the barb fitting body 151 and can be detachably inserted into the connecting pipe 70. Multiple barb projections 154 may be formed at intervals along the central axis of the barb fitting body 151 on the outer circumferential surface of such a barb fitting clamp 153. Such barb projections 154 may have a shape in which the diameter decreases as it moves away from the barb fitting body 151. In other words, the barb projections 154 may have a frustoconical shape. Therefore, the airtightness of the connecting pipe 70 inserted into the barb fitting clamp 153 can be improved by the multiple barb projections 154. Thus, the barb fitting section 150 has relatively improved airtightness compared to the one-touch fitting section 140, and can prevent leakage of cooling fluid at the connection point between the connecting pipe 70 and the check valve 80.

[0086] On the other hand, the barb fitting section 150 is provided at the connection point between the relief valve 120 and the chamber 20, preventing leakage of the cooling fluid. Furthermore, the barb fitting section 150 is also provided at the connection point between the discharge valve 30 and the chamber 20, preventing leakage of the cooling fluid.

[0087] The auxiliary barb fitting section 150' can also serve to connect the connecting pipe 70 and the storage container 10. A flow path can be formed inside such an auxiliary barb fitting section 150' that connects the connecting pipe 70 and the storage container 10.

[0088] Furthermore, the auxiliary barb fitting section 150' may include a barb fitting body 151, a barb fitting coupling section 152, and a barb fitting clamp 153. Such an auxiliary barb fitting section 150' is identical to the barb fitting section 150 in all other respects, except that the barb fitting coupling section 152 is detachably connected to the storage container 10 and the barb fitting clamp 153 is detachably connected to the connecting pipe 70, so further details are omitted.

[0089] On the other hand, the skin care device according to one embodiment of the present invention can receive a supply of cooling fluid discharged from the cooling system for the skin care device according to one embodiment of the present invention.

[0090] According to the present invention, a cooling system for a skin care device according to one embodiment of the present invention has the effect of inducing pain relief and soothing of the skin by delivering a cooling fluid to a target area of ​​the skin, and preventing the occurrence of burns on the skin.

[0091] Furthermore, the cooling system for a skin care device according to one embodiment of the present invention has the effect of being able to transfer all of the cooling fluid stored in the storage container 10 to the chamber 20.

[0092] Although embodiments of the present invention have been described above with reference to the attached drawings, a person of ordinary skill in the art to which the present invention pertains will understand that the present invention can be implemented in other specific forms without changing its technical idea or essential features. Accordingly, the embodiments described above should be understood in all respects as illustrative and not limiting.
