Description

[Technical Field]

[0001] The present invention relates to a cooling system for a skin management device. [Background technology]

[0002] Currently, skin care devices are being developed that maintain clean skin by removing wrinkles, restoring skin elasticity, and removing sebum, because clean and maintained skin makes people look younger and contributes to an attractive appearance.

[0003] Skin management devices include a type that transmits ultrasound 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, the method of transmitting high frequency to the skin involves applying high frequency generated by an RF electrode to the target area of ​​the skin through the epidermis. As a result, coagulation necrosis of the target area of ​​the skin is induced, removing collagen and elastic fibers in the target area of ​​the skin, and new collagen and elastic fibers can be formed. In addition, coagulation necrosis of the target area of ​​the skin is also effective in improving skin pigmentation, acne scars, and wrinkles.

[0005] Furthermore, conventional skin care devices have a problem in that if the high frequency application process of the RF electrode continues, the temperature of the target area of ​​the skin rises excessively, causing burns to the target area of ​​the skin. Summary of the Invention [Problem to be solved by the invention]

[0006] The present invention has been made in consideration of the above circumstances, and its purpose is to provide a cooling system for a skin management device that can relieve pain and induce skin soothing by transmitting a cooling fluid to a target area of ​​the skin where high frequency is applied, and can prevent the occurrence of burns on the skin.

DETAILED DESCRIPTION OF THE INVENTION

[0026] The advantages and features of the present invention, as well as methods for achieving them, will become apparent from the following detailed description of the embodiments in conjunction with the accompanying drawings. However, the present invention is not limited to the embodiments disclosed below, and may be embodied in various different forms. However, the present embodiments are provided to complete the disclosure of the present invention and to allow those skilled in the art to fully understand the scope of the present invention, and the present invention is defined only by the scope of the claims.

[0027] The terms used in this specification are for the purpose of describing the embodiments and are not intended to limit the present invention. In this specification, the singular includes the plural unless otherwise specified. As used in this specification, the words "comprises" and / or "comprising" do not exclude the presence or addition of one or more other elements other than the elements mentioned.

[0028] Unless otherwise defined, all terms (including technical and scientific terms) used in this specification are used in the sense that they can be commonly understood by those skilled in the art to which the present invention belongs. Furthermore, terms defined in commonly used dictionaries are not to be interpreted ideally or excessively unless they are clearly and specifically defined.

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

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

[0031] As shown in FIG. 1, a cooling system for a skin management device according to an 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 a cooling fluid. The cooling fluid stored in the storage container 10 can be supplied to the chamber 20. The cooling fluid can be a cooling gas or a cooling liquid. For example, HFO (hydrofluoroolefin) can be used as the cooling gas, and water can be used as the cooling liquid.

[0033] As shown in FIG. 2, the storage container 10 may be formed in an overall cylindrical shape. In addition, a storage container outlet 11 for discharging the cooling fluid may be provided on one side of the storage container 10. The storage container outlet 11 may have a shape whose diameter decreases as it goes away from the storage container 10. Meanwhile, the storage container 10 may be detachably coupled to a storage container mounting part 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 mounting part 60, and a new storage container 10 can be coupled to the storage container mounting part 60. At this time, the new storage container 10 may be filled with the cooling fluid.

[0034] The chamber 20 may be filled with the cooling fluid transferred from the storage container 10. The cooling fluid filled in the chamber 20 may be discharged to the outside through the discharge valve 30. For example, the chamber 20 may be formed in a longitudinal direction as a whole.

[0035] 3, the exhaust valve 30 serves to exhaust or cut off the cooling fluid filled in the chamber 20. For example, the exhaust valve 30 may be a mouth valve or a solenoid valve.

[0036] For example, the exhaust valve 30 may connect the chamber 20 to the skin management device. In this case, the cooling fluid discharged through the exhaust valve 30 may be delivered to the skin management device. As a result, the cooling fluid delivered to the skin management device may prevent breakdowns due to temperature rises in the skin management device. Here, the exhaust valve 30 may connect to the skin management device via a coupler 160.

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

[0038] For example, the discharge valve 30 can be opened or closed under the control of a control unit (not shown) to discharge or cut off the cooling fluid filled in the chamber 20. Here, the control unit can be a microcomputer.

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

[0040] Meanwhile, when the water level measured by the fluid sensor 40 remains constant for a set time, the internal pressure of the storage container 10 is equal to or lower than the internal pressure of the chamber 20, and therefore the cooling fluid stored in the storage container 10 may not be transferred to the chamber 20. Therefore, it is necessary to increase the internal pressure of the storage container 10 so that the cooling fluid stored in the storage container 10 is transferred without remaining in the chamber 20. For example, the set time may be 10 to 30 seconds.

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

[0042] The pressurizing unit 50 can include a pressurizing heater 51, a heat insulating material 52, and a pressurizing temperature sensor (not shown).

[0043] When the water level measured by the fluid sensor 40 remains constant, the pressurizing heater 51 heats the storage container 10 to increase the internal pressure of the storage container 10. 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 to a range of room temperature to 50° C. For example, the room temperature can be 1° C. to 30° C., but the present invention is not limited thereto.

[0045] The heat insulating material 52 surrounds the storage container 10 and the pressurizing heater 51 and serves to keep 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 heat loss and pressure loss of the storage container 10 can be reduced by the heat insulating material 52.

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

[0047] For example, when the cooling fluid filled in 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 may determine that the remaining amount of cooling fluid stored in the storage container 10 is sufficient.

[0048] As another example, if the water level measured by the fluid sensor 40 decreases when the cooling fluid filled in the chamber 20 is discharged, this may indicate that there is only a small amount of cooling fluid or that there is no cooling fluid stored in the storage container 10, and therefore the cooling fluid stored in the storage container 10 is not being transferred to the chamber 20. In this case, the control unit may determine that the remaining amount of cooling fluid stored in the storage container 10 is insufficient and emit an alarm sound indicating that the remaining amount of the cooling fluid in the storage container 10 should be checked.

[0049] The cooling system for a skin management device according to one embodiment of the present invention may further include a storage container loading unit 60, a connecting pipe 70, a check valve 80, a pressure maintaining unit 90, a storage container pressure sensor 100, and a chamber pressure sensor 110.

[0050] The storage container 10 may be detachably mounted in the storage container mounting unit 60. As shown in Fig. 2, a storage container connection unit 61 to be inserted into the storage container discharge unit 11 of the storage container 10 may be formed on one side of the storage container mounting unit 60. The storage container connection unit 61 has a smaller diameter than the storage container discharge unit 11 and may be inserted into the storage container discharge unit 11. In addition, a pipe connection unit connecting the insertion unit of the storage container 10 to the connecting pipe 70 may be formed on the other side of the storage container mounting unit 60.

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

[0052] The check valve 80 is provided in the connecting pipe 70 and serves to control the flow of the cooling fluid in the connecting pipe 70 in the direction toward the chamber 20 .

[0053] The pressure maintaining unit 90 is installed in the chamber 20 and serves to maintain a constant internal pressure of 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 greater than the internal pressure of the chamber 20, so that the cooling fluid stored in the storage container 10 can be easily transferred to the chamber 20.

[0054] The pressure maintaining unit 90 can include a pressure maintaining heater 91 and a pressure maintaining temperature sensor.

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

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

[0057] The pressure maintaining temperature sensor can measure the internal temperature of the chamber 20. The pressure maintaining temperature sensor can transmit the measured value of the internal temperature of the chamber 20 to the pressure maintaining heater 91. Thereafter, the pressure maintaining heater 91 can heat the chamber 20 at regular time intervals based on the measured value of the internal temperature of the storage container 10 transmitted from the pressure maintaining temperature sensor so that the internal temperature of the chamber 20 is maintained constant.

[0058] The storage container pressure sensor 100 can serve to measure the internal pressure of the storage container 10, and the chamber pressure sensor 110 can serve to measure the internal pressure of the chamber 20. Here, the measurement value of the internal pressure of the storage container 10 measured by the storage container pressure sensor 100 and the measurement value of the internal pressure of the chamber 20 measured by the chamber pressure sensor 110 can be transmitted to the control unit. Thereafter, the control unit can control the pressurizing unit 50 to increase the internal pressure of the storage container 10 when the measurement value of the internal pressure of the storage container 10 transmitted from the storage container pressure sensor 100 is equal to or smaller than the measurement value of the internal pressure of the chamber 20 transmitted from the chamber pressure sensor 110.

[0059] The cooling system for a skin management device according to an embodiment of the present invention may further include a relief valve 120 .

[0060] The relief valve 120 can be opened or closed by a user's operation to discharge or stop the cooling fluid filled in the chamber 20 to the outside.

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

[0062] Hereinafter, the operation of the cooling system for a skin management device according to an embodiment of the present invention will be described.

[0063] 4 to 6 are front views showing the operation process of the cooling system for a skin management device according to an embodiment of the present invention. The following process 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 FIG. 4).

[0065] Thereafter, the fluid sensor 40 measures the level of the cooling fluid filled in the chamber 20. If the level of the cooling fluid filled in the chamber 20 measured by the fluid sensor 40 remains constant, the cooling fluid stored in the storage container 10 may not be transferred to the chamber 20 through the connecting pipe 70 and the check valve 80. In this case, the pressurizing unit 50 increases the internal pressure of the storage container 10 so that the internal pressure of the storage container 10 becomes greater than the internal pressure of the chamber 20. As a result, the cooling fluid stored in the storage container 10 may be transferred through the connecting pipe 70 and the check valve 80 without remaining in the chamber 20.

[0066] Next, the control unit controls the discharge valve 30 to open, and the cooling fluid filled in the chamber 20 can be discharged to the target object through the discharge valve 30 (see FIG. 5).

[0067] At this time, when the cooling fluid filled in 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 may determine that the remaining amount of cooling fluid stored in the storage container 10 is sufficient.

[0068] In addition, if the water level measured by the fluid sensor 40 decreases when the cooling fluid filled in the chamber 20 is discharged, it may be that the amount of cooling fluid stored in the storage container 10 is small or nonexistent, and the cooling fluid stored in the storage container 10 is not being transferred to the chamber 20. In this case, the control unit may determine that the remaining amount of cooling fluid stored in the storage container 10 is insufficient, and may emit an alarm sound indicating that the remaining amount of the cooling fluid in the storage container 10 should be checked.

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

[0070] Meanwhile, when the cooling fluid filled in the chamber 20 is completely drained to move the cooling system for the skin management device or to repair a malfunction, the cooling fluid filled in the chamber 20 is completely drained through the relief valve 120, thereby eliminating the need to use the barb fitting 150 described below, which prevents leakage between the relief valve 120 and the relief pipe 130. Therefore, the relief valve 120 and the relief pipe 130 can be easily and detachably coupled via the one-touch fitting 140.

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

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

[0073] The one-touch fitting 140 can serve to separably connect the relief valve 120 and the relief pipe 130. A flow path that connects the relief valve 120 and the relief pipe 130 can be formed inside the one-touch fitting 140.

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

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

[0076] The quick fitting coupling portion 142 is provided on one side of the quick fitting body 141 and can be detachably coupled to the relief valve 120. For example, the quick fitting coupling portion 142 can have a bolt shape 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 pipe 130 can be easily inserted in a separable manner. Therefore, the relief valve 120 and the relief pipe 130 can be easily connected by the one-touch fitting part 140, which reduces the time required for the worker to assemble the relief valve 120 and the relief pipe 130 and to separate and fix them, thereby improving the worker's work efficiency.

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

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

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

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

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

[0083] Barb fitting body 151 is the basic body of barb fitting portion 150 and serves to connect barb fitting connecting portion 152 and barb fitting clamp 153 .

[0084] Barb fitting coupling portion 152 is provided on one side of barb fitting body 151 and can be detachably coupled to chamber 20. As an example, barb fitting coupling portion 152 can have a bolt shape and can be screwed into 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. A plurality of barb protrusions 154 can be formed at intervals along the central axis of the barb fitting body 151 on the outer circumferential surface of the barb fitting clamp 153. The barb protrusions 154 can have a shape in which the diameter decreases as they extend away from the barb fitting body 151. In other words, the barb protrusions 154 can have a truncated cone shape. Therefore, the connecting pipe 70 inserted into the barb fitting clamp 153 can be improved in airtightness with the barb fitting clamp 153 by the plurality of barb protrusions 154. As such, the barb fitting 150 has relatively improved airtightness compared to the snap fitting 140, thereby preventing leakage of cooling fluid from the connecting portion between the connecting pipe 70 and the check valve 80.

[0086] Meanwhile, the barb fitting 150 is provided at the connection portion between the relief valve 120 and the chamber 20 to prevent leakage of the cooling fluid. The barb fitting 150 is also provided at the connection portion between the discharge valve 30 and the chamber 20 to prevent leakage of the cooling fluid.

[0087] The auxiliary barb fitting 150' may also function to connect the connecting pipe 70 and the storage container 10. A flow path that communicates the connecting pipe 70 and the storage container 10 may be formed inside the auxiliary barb fitting 150'.

[0088] In addition, auxiliary barb fitting 150' may include a barb fitting body 151, a barb fitting coupling portion 152, and a barb fitting clamp 153. Such auxiliary barb fitting 150' is identical to barb fitting 150 except that barb fitting coupling portion 152 is detachably coupled to storage container 10 and barb fitting clamp 153 is detachably coupled to connecting pipe 70, and other details are omitted.

[0089] Meanwhile, the skin management device according to an embodiment of the present invention may be supplied with cooling fluid discharged from the cooling system for the skin management device according to an embodiment of the present invention.

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

[0091] In addition, the cooling system for a skin management device according to an embodiment of the present invention has the advantage that all of the cooling fluid stored in the storage container 10 can be transferred to the chamber 20.

[0092] Although the embodiments of the present invention have been described above with reference to the accompanying drawings, those skilled in the art will understand that the present invention can be embodied in other specific forms without changing the technical spirit or essential features of the present invention. Therefore, the above-described embodiments should be understood as illustrative in all respects and not restrictive.
