Description

Technical Field

[0001] This disclosure relates to a method of operating a tip and valve for skin management, including a handheld component thereof. Background Technology

[0002] High-frequency therapy devices are skin rejuvenation treatments that generate heat from high-frequency output in the skin tissue of the patient, causing denaturation and contraction of collagen fibers, thereby producing collagen regeneration and wrinkle improvement effects.

[0003] This high-frequency therapeutic device operates by generating high frequencies, so the high-frequency electrodes may generate heat when outputting high frequencies.

[0004] Furthermore, when the high-frequency therapeutic device uses a refrigerant to cool the high-frequency electrodes during treatment, the high-frequency electrodes need to be sufficiently cooled, thus requiring continuous use of the refrigerant.

[0005] Therefore, existing high-frequency therapeutic devices require continuous use of refrigerant, and the refrigerant vaporizes quickly, causing the tip temperature to rise rapidly and increasing gas consumption, thus increasing the cost of refrigerant use.

[0006] Furthermore, existing high-frequency therapy devices cannot maintain a low internal temperature, thus reducing cooling efficiency. Summary of the Invention Technical issues

[0047] The skin management tip according to this disclosure may include: an injection section disposed inside a housing and including a refrigerant delivery path formed for injecting cooling gas; an exhaust section coupled to the injection section and including an exhaust path formed for discharging the cooling gas to the outside; and a valve coupled to the injection section and the exhaust section, blocking external air flowing in through the refrigerant delivery path, and opening and closing according to the pressure of the cooling gas so that the cooling gas is retained while being discharged to the outside through the exhaust path.

[0048] This skin management tip can prevent pain and burns caused by high-frequency electrode heating, prevent increased refrigerant consumption and operating costs, prevent internal icing, and improve cooling efficiency by keeping the internal temperature low.

[0049] The following is a detailed description of the tip used for skin management.

[0050] Figures 1 to 4 This is a diagram illustrating the construction of a skin management tip according to the present disclosure.

[0051] Reference Figures 1 to 4 The skin management tip 100 may include a first housing 110, a first injection section 130, a first discharge section 140, 150, 160, and a first valve 170.

[0052] The first housing 110 serves to discharge cooling gas and prevent heat exchange between the interior and exterior while blocking the flow of cooling gas. The first injection section 130 can be disposed within the first housing 110 and can include refrigerant delivery paths A11 to A18 formed for injecting cooling gas. For example, the first injection section 130 can be configured as an ejector, but is not limited thereto; it can be any component capable of injecting low-boiling-point, high-pressure, liquid cooling gas. Furthermore, the first injection section 130 can also be disposed inside the housing 110.

[0053] The first discharge portions 140, 150, and 160 can be combined with the first injection portion 130 and may include discharge paths B11 to B14 configured to discharge cooling gas to the outside. Here, the first discharge portions 140, 150, and 160 may include a first guide member 140, a first cap 150, and a first fastening member 160. In this case, the skin management tip 100 can be configured such that the first injection portion 130, the first guide member 140, and the first cap 150 are inserted into the first housing 110, and can be combined with the first housing 110 by means of the first fastening member 160.

[0054] Here, the first guide member 140 may be configured to guide the first injection portion 130 and the first valve 170 to engage with the housing 110. The first cover 150 may be configured to protect the first injection portion 130, the first valve 170, and the first guide member 140. The first fastening member 160 may be configured to fasten to the first cover 150.

[0055] For example, the first fastening member 160 may include at least one first fastening protrusion 161 to fasten the first cover 150. Furthermore, the first fastening member 160 may also include at least one first connection hole 162 to allow an external device, such as a handheld device, to be electrically connected to a portion of the first electrode member 120. In this case, the first electrode member 120 may be a member that applies high frequency (RF) signals to the dermis of the skin. For example, the first electrode member 120 may be a planar electrode for transmitting RF power to a very thin flexible film-type PCB (F-PCB) and may function to transfer the low temperature generated by the vaporization of the refrigerant to the opposite side (skin) for heat exchange (skin cooling). Furthermore, the first fastening member 160 may also include at least one first discharge hole 163 to allow cooling gas to be discharged to the outside by opening the first valve 170.

[0056] The first valve 170 can be combined with the first injection section 130 and the first discharge sections 140, 150, and 160, and blocks external air flowing in through refrigerant transfer paths A11 to A18. It opens and closes according to the pressure of the cooling gas, so that the cooling gas is retained while being discharged to the outside through discharge paths B11 to B14. For example, the first valve 170 may include a check valve and an electronic valve, and the electronic valve may include a solenoid valve, but is not limited thereto. Furthermore, the solenoid valve may also be equipped on a handheld device and can function as follows: if the temperature sensed by a temperature sensor equipped on the tip reaches a preset target temperature, it discharges refrigerant while cooling the temperature below the preset target temperature.

[0057] According to this disclosure, the skin management tip 100, based on the internal space formed by the first housing 110, the first electrode component 120, the first injection section 130, the first discharge sections 140, 150, 160, and the first valve 170, can transfer cooling gas through refrigerant transfer paths A11 to A18, and can discharge the cooling gas to the outside through the opening operation of the first valve 170 and the discharge paths B11 to B14. Here, the discharge paths B11 to B14, as paths for discharging the cooling gas to the outside, can prevent humid external air from flowing into the lower-temperature interior of the first injection section 130. At this time, the vaporized gas is discharged to the outside along the discharge paths B11 to B14 through the first valve 170, and the gas passing through the first valve 170 cannot flow back into the interior of the first injection section 130. Furthermore, the first valve 170 can prevent warm external air from flowing in, prevent internal icing, and maintain the interior at a lower temperature.

[0058] Figures 5 to 8 This is another example illustrating the composition of a skin management tip according to the present disclosure.

[0059] Reference Figures 5 to 8 The skin management tip 500 may include a second housing 510, a second injection section 530, a second discharge section 540, 550, 560, and a second valve 570.

[0060] The second housing 510 serves to discharge cooling gas and prevent heat exchange between the interior and exterior while blocking the flow of cooling gas. A second injection section 530 can be provided within the second housing 510 and can include refrigerant delivery paths A21 to A29 formed for injecting cooling gas. For example, the second injection section 530 can be configured as an injector. Here, the second injection section 530 can include an injector body 531, a diffuser plate 532, and a fixing member 533. The injector body 531 can be fixed to the diffuser plate 532 by the fixing member 533. This second injection section 530 can uniformly diffuse and inject cooling gas output from the injector body 531 in a uniform amount through the diffuser plate 532 containing a plurality of holes h1 with a predetermined spacing. Furthermore, the second injection section 530 is not limited to this and can be configured with all components capable of uniformly diffusing and injecting low-boiling-point, high-pressure, liquid-state cooling gas in a uniform amount. The second injection section 530 can also be provided inside the housing 510.

[0061] Furthermore, the second injection section 530 is also equipped with a second injection nozzle 590. For example, the second injection nozzle 590 can be a fine nozzle arranged at equal intervals. In this case, the second injection nozzle 590 can also have a wide injection angle to uniformly cool the entire area of ​​the second electrode component 520 according to the area of ​​the second electrode component 520. As the cooling gas is sprayed over a large area in a spray manner, the second injection nozzle 590 can uniformly cool the entire area of ​​the second electrode component 520, and the cooling gas sprayed by the second injection nozzle 590 adheres to the second electrode component 520 and is vaporized while reducing the internal temperature.

[0062] The second discharge sections 540, 550, and 560 can be combined with the second injection section 530 and may include discharge paths B21 to B28 configured to discharge cooling gas to the outside. Here, the second discharge sections 540, 550, and 560 may include a second guide member 540, a second cap 550, and a second fastening member 560. In this case, the skin management tip 500 can be configured such that the second injection section 530, the second guide member 540, and the second cap 550 are inserted into the second housing 510, and can be combined with the second housing 510 by means of the second fastening member 560.

[0063] Here, the second guide member 540 may be configured to guide the second injection section 530 and the second valve 570 into contact with the housing 510. The second cover 550 may be configured to protect the second injection section 530, the second valve 570, and the second guide member 540. The second fastening member 560 may be configured to fasten to the second cover 550.

[0064] For example, the second fastening member 560 may include at least one second fastening protrusion 561 to fasten the second cover 550. Furthermore, the second fastening member 560 may also include at least one second connection hole 562 to allow an external device, such as a handheld device, to be electrically connected to a portion of the second electrode member 520. In this case, the second electrode member 520 may be a member that applies high frequency (RF) signals to the dermis of the skin. For example, the second electrode member 520 may be a planar electrode for transmitting RF power to a very thin flexible film-type PCB (F-PCB) and may function to transfer the low temperature generated by the vaporization of the refrigerant to the opposite side of the film (skin) for heat exchange (skin cooling). Additionally, the second fastening member 560 may also include at least one second discharge hole 563 to allow cooling gas to be discharged to the outside by opening the second valve 570.

[0065] The second valve 570 can be combined with the second injection section 530 and the second discharge sections 540, 550, and 560, and blocks external air flowing in through refrigerant transfer paths A21 to A29. It opens and closes according to the pressure of the cooling gas, so that the cooling gas is retained while being discharged to the outside through discharge paths B21 to B28. For example, the second valve 570 may include a check valve and an electronic valve, and the electronic valve may include a solenoid valve, but is not limited thereto. Furthermore, the solenoid valve may also be equipped on a handheld device and can function as follows: if the temperature sensed by a temperature sensor equipped on the tip reaches a preset target temperature, it discharges refrigerant while cooling the temperature below the preset target temperature.

[0066] According to this disclosure, the skin management tip 500, based on the internal space formed by the second housing 510, the second electrode component 520, the second injection section 530, the second discharge sections 540, 550, 560, and the second valve 570, can uniformly diffuse and deliver cooling gas in a uniform amount through refrigerant transfer paths A11 to A18, and can simultaneously discharge the cooling gas to the outside by opening the second valve 570 and discharging it through discharge paths B21 to B28. Here, discharge paths B21 to B28, as paths for discharging the cooling gas to the outside, can prevent humid external air from flowing into the lower-temperature interior of the second injection section 530. At this time, the vaporized gas is discharged to the outside along the discharge paths B21 to B28 through the second valve 570, and the gas passing through the second valve 570 cannot flow back into the interior of the second injection section 530. Furthermore, the second valve 570 can prevent warm external air from flowing in, prevent internal icing, and maintain the interior at a lower temperature.

[0067] Figures 9 to 12 This is yet another example illustrating the construction of a skin management tip according to the present disclosure.

[0068] Reference Figures 9 to 12 The skin management tip 900 may include a third housing 910, a third injection section 930, a third discharge section 940, 950, 960, and a third valve 970.

[0069] The third housing 910 serves to discharge cooling gas and prevent heat exchange between the interior and exterior while blocking the flow of cooling gas. A third injection section 930 can be provided within the third housing 910 and may include refrigerant delivery paths A31 to A42 formed for injecting cooling gas. For example, the second injection section 930 may be provided as an injector. Here, the third injection section 930 may include an injector body 931, a diffuser plate 932, and a fixing member 933. In this case, the injector body 931 can be fixed to the diffuser plate 932 by the fixing member 933. The third injection section 930 can uniformly diffuse and inject the cooling gas output from the injector body 931 in a uniform and large-area quantity through the diffuser plate 932, which includes a plurality of holes h2 with a predetermined spacing. Furthermore, the third injection section 930 is not limited to this and may be equipped with all components capable of uniformly diffusing and injecting low-boiling-point, high-pressure, liquid-state cooling gas in a uniform and large-area quantity. The third injection section 930 may also be provided inside the housing 910.

[0070] Furthermore, the third injection unit 930 may also be equipped with a third injection nozzle 990. For example, the third injection nozzle 990 may be a fine nozzle arranged at equal intervals. In this case, the third injection nozzle 990 may have a wide injection angle to uniformly cool the entire area of ​​the third electrode component 920 according to its area. As the cooling gas is sprayed over a large area by the third injection nozzle 990, the entire area of ​​the third electrode component 920 can be uniformly cooled, and the cooling gas sprayed by the third injection nozzle 990 adheres to the third electrode component 920 and is vaporized while reducing the internal temperature.

[0071] The third discharge sections 940, 950, and 960 can be combined with the third injection section 930 and may include discharge paths B31 to B44, forming a system for discharging cooling gas to the outside. Here, the third discharge sections 940, 950, and 960 may include a third guide member 940, a third cover 950, and a third fastening member 960. In this case, the skin management tip 900 can be configured such that the third injection section 930, the third guide member 940, and the third cover 950 are inserted into the third housing 910, and can be combined with the third housing 910 by means of the third fastening member 960.

[0072] Here, the third guide member 940 may be configured to guide the third injection section 930 and the third valve 970 to engage with the third housing 910. The third cover 950 may be configured to protect the third injection section 930, the third valve 970, and the third guide member 940. The third fastening member 960 may be configured to fasten to the third housing 910 and the third cover 950.

[0073] For example, the third fastening member 960 may include at least one third fastening protrusion 961 to fasten the third cover 950 while in contact with the third housing 910. Furthermore, the third fastening member 960 may also include at least one third connection hole 962 to allow an external device, such as a handheld device, to be electrically connected to a portion of the third electrode member 920. In this case, the third electrode member 920 may be a member that applies high frequency (RF) signals to the dermis of the skin. For example, the third electrode member 920 may be a planar electrode for transmitting RF power to a very thin flexible film-type PCB (F-PCB) and may function to transfer the low temperature generated by the vaporization of the refrigerant to the opposite side of the film (skin) for heat exchange (skin cooling). Additionally, the third fastening member 960 may also include at least one third discharge hole 963 to allow cooling gas to be discharged to the outside by opening the third valve 970.

[0074] The third valve 970 can be combined with the third injection section 930 and the third discharge sections 940, 950, and 960, and blocks external air flowing in through the refrigerant transfer paths A31 to A42. It opens and closes according to the pressure of the cooling gas, so that the cooling gas is retained while being discharged to the outside through the discharge paths B31 to B44. For example, the third valve 970 may include a check valve and an electronic valve, and the electronic valve may include a solenoid valve, but is not limited thereto. Furthermore, the solenoid valve may also be equipped on a handheld device and can function such that if the temperature sensed by a temperature sensor equipped on the tip reaches a preset target temperature, it discharges refrigerant while cooling the temperature below the preset target temperature.

[0075] According to this disclosure, the skin management tip 900, based on the internal space formed by the third housing 910, the third electrode component 920, the third injection section 930, the third discharge sections 940, 950, 960, and the third valve 970, can uniformly diffuse and transfer cooling gas in a large quantity and over a uniform area through refrigerant transfer paths A31 to A42. Furthermore, the opening operation of the third valve 970 and the discharge paths B31 to B44 allow the cooling gas to be retained while simultaneously being discharged to the outside. Here, the discharge paths B31 to B44, as paths for discharging the cooling gas to the outside, prevent humid external air from flowing into the lower-temperature interior of the third injection section 930. At this time, the vaporized gas is discharged to the outside along the discharge paths B31 to B44 through the third valve 970, and the gas passing through the third valve 970 cannot flow back into the interior of the third injection section 930. Furthermore, the third valve 970 prevents warm external air from flowing in, prevents internal icing, and maintains the interior at a lower temperature.

[0076] According to the skin management tips 100, 500, and 900 of this disclosure, at least one of the first valve 170, second valve 570, and third valve 970 can remain closed until the pressure of the cooling gas reaches a preset reference pressure, and can also be opened when the pressure of the cooling gas reaches the reference pressure. At this time, when the pressure of the cooling gas reaches the reference pressure, at least one of the first valve 170, second valve 570, and third valve 970 can be opened at an opening level within a preset pressure range.

[0077] For example, when the pressure of the cooling gas is within a preset first pressure range, at least one of the first valve 170, the second valve 570, and the third valve 970 can operate at a preset fine opening level in association with the first pressure range. In this case, the first pressure range can be a low-level pressure range.

[0078] For example, when the pressure of the cooling gas is in a second pressure range higher than a preset first pressure range, at least one of the first valve 170, the second valve 570, and the third valve 970 can be opened at a preset semi-open level in association with the second pressure range. In this case, the second pressure range can be a middle level pressure range.

[0079] For example, when the pressure of the cooling gas is in a third pressure range that is higher than a preset second pressure range, at least one of the first valve 170, the second valve 570, and the third valve 970 can be opened at a preset fully open level in association with the third pressure range. In this case, the third pressure range can be a high-level pressure range.

[0080] In this disclosure, at least one of the skin management tips 100, 500, and 900 can be replaceably mounted on a handheld device. In this case, the handheld device may include a control portion for controlling at least one of the skin management tips 100, 500, and 900.

[0081] Figure 13 The configuration of the control section of the handheld device equipped with a skin management tip according to the present disclosure is shown.

[0082] Reference Figure 13The control unit 1100 of the handheld device 1000 can be implemented using a memory 1111 that stores data of algorithms for controlling the operation of the components within the device or programs relating to reproduction algorithms, and at least one processor 1112 that performs the aforementioned operations using the data stored in the memory 1111. Here, the memory 1111 and the processor 1112 can each be implemented using separate chips. Furthermore, the memory 1111 and the processor 1112 can also be implemented using a single chip.

[0083] The memory 1111 can store data supporting various functions of the device and programs for the operation of the control unit. It can store input / output data, multiple application programs (or applications) driven in the device, data for the operation of the device, and instructions. At least some of these applications can be downloaded from an external server via wireless communication.

[0084] This memory 1111 may include at least one type of storage medium selected from flash memory, hard disk, solid-state drive (SSD), silicon disk drive (SDD), media card micro, card-type memory (e.g., Secure Digital (SD) or Extreme Digital (XD) memory), random access memory (RAM), static random access memory (SRAM), read-only memory (ROM), electrically erasable programmable read-only memory (EEPROM), programmable read-only memory (PROM), magnetic storage, magnetic disk, and optical disk. Furthermore, the memory 1111 is separate from this device, but may also be a wired or wirelessly connected database.

[0085] When the pressure of the cooling gas is within a preset first pressure range, the processor 1112 can also adjust the opening speed of at least one of the first valve 170, the second valve 570, and the third valve 970. In this case, the processor 1112 can adjust the opening speed of at least one of the preset first valve 170, the second valve 570, and the third valve 970 in accordance with the first pressure range to perform rapid opening, average opening, or delayed opening operations at a preset fine opening level in association with the first pressure range.

[0086] When the pressure of the cooling gas is in a second pressure range higher than a preset first pressure range, the processor 1112 can also adjust the opening speed of at least one of the first valve 170, the second valve 570, and the third valve 970. In this case, the processor 1112 can adjust the opening speed of at least one of the preset first valve 170, the second valve 570, and the third valve 970 in accordance with the second pressure range to perform rapid opening, average opening, or delayed opening operations at a preset half-open level in association with the second pressure range.

[0087] When the pressure of the cooling gas is in a third pressure range that is higher than the preset second pressure range, the processor 1112 can also adjust the opening speed of at least one of the first valve 170, the second valve 570, and the third valve 970. In this case, the processor 1112 can adjust the opening speed of at least one of the preset first valve 170, the second valve 570, and the third valve 970 in accordance with the third pressure range to perform rapid opening, average opening, or delayed opening operations at a preset fully open level in association with the third pressure range.

[0088] At least one of the first injection control unit 180, second injection control unit 580, and third injection control unit 980 of the skin management tip 100, 500, and 900 according to this disclosure can be installed in at least one of the first injection unit 130, second injection unit 530, and third injection unit 930, and can also control the injection volume of cooling gas according to the pressure of the cooling gas. In this case, at least one of the first injection control unit 180, second injection control unit 580, and third injection control unit 980 can be equipped with a fourth valve inside at least one of the first injection unit 130, second injection unit 530, and third injection unit 930. For example, the fourth valve can be equipped with a check valve, but is not limited thereto, and can be equipped with a solenoid valve. Furthermore, the fourth valve can also be equipped with both a check valve and a solenoid valve simultaneously.

[0089] Here, the processor 1112 can control at least one of the first injection control unit 180, the second injection control unit 580, and the third injection control unit 980 according to the pressure of the cooling gas, so as to control the injection amount of the cooling gas. For example, when the pressure of the cooling gas is within a preset first pressure range, the processor 1112 can adjust the opening state of at least one of the preset first injection control unit 180, the second injection control unit 580, and the third injection control unit 980 in accordance with the first pressure range, so as to inject the cooling gas at a preset first injection amount level associated with the first pressure range. As another example, when the pressure of the cooling gas is within a second pressure range higher than the preset first pressure range, the processor 1112 can adjust the opening state of at least one of the preset first injection control unit 180, the second injection control unit 580, and the third injection control unit 980 in accordance with the second pressure range, so as to inject the cooling gas at a second injection amount level lower than the preset first injection amount level associated with the second pressure range. For example, when the pressure of the cooling gas is in a third pressure range that is higher than a preset second pressure range, the processor 1112 can adjust the opening state of at least one of the preset first injection control unit 180, second injection control unit 580, and third injection control unit 980 in accordance with the third pressure range, so as to inject the cooling gas at a third injection amount level that is lower than a preset second injection amount level in association with the third pressure range. Here, the first injection amount level may be higher than the second injection amount level, and the second injection amount level may be higher than the third injection amount level. At this time, the opening state may be at least one of the opening degree and the opening speed.

[0090] Figure 14 and Figure 15 This is a sequence diagram illustrating, as an example, the operation of a valve included in a skin management tip according to the present disclosure. (Refer to...) Figure 14 The operation method of at least one of the first valve 170, the second valve 570, and the third valve 970 may include a sensing step (S1410), a judgment step (S1420), a holding step (S1430), and an opening operation step (S1440).

[0091] In the sensing step, the pressure of the cooling gas injected through the refrigerant delivery paths A11 to A18, A21 to A29, A31 to A42 of the skin management tips 100, 500, 900 can be sensed by at least one of the first valve 170, the second valve 570, and the third valve 970 (S1410).

[0092] In the judgment step, at least one of the first valve 170, the second valve 570, and the third valve 970 can be used to determine whether the pressure of the cooling gas has reached the preset reference pressure (S1420).

[0093] During the holding step, if the pressure of the cooling gas does not reach the preset reference pressure, the closed operation can be maintained by at least one of the first valve 170, the second valve 570, and the third valve 970 (S1430).

[0094] In the opening operation step, when the pressure of the cooling gas reaches the preset reference pressure, the opening operation can be performed by at least one of the first valve 170, the second valve 570, and the third valve 970 at an opening level within a preset pressure range (S1440).

[0095] For example, when the pressure of the cooling gas is within a preset first pressure range, at least one of the first valve 170, the second valve 570, and the third valve 970 can operate at a preset fine opening level in association with the first pressure range. In this case, the first pressure range can be a low-level pressure range.

[0096] For example, when the pressure of the cooling gas is in a second pressure range higher than a preset first pressure range, at least one of the first valve 170, the second valve 570, and the third valve 970 can be opened at a preset semi-open level in association with the second pressure range. In this case, the second pressure range can be a middle level pressure range.

[0097] For example, when the pressure of the cooling gas is in a third pressure range that is higher than a preset second pressure range, at least one of the first valve 170, the second valve 570, and the third valve 970 can be opened at a preset fully open level in association with the third pressure range. In this case, the third pressure range can be a high-level pressure range.

[0098] Reference Figure 15 The valve operation method also includes a first judgment step (S1441), a first opening operation step (S1442), a second judgment step (S1443), a second opening operation step (S1444), a third judgment step (S1445), and a third opening operation step (S1446).

[0099] In the first determination step, the processor 1112 of the handheld device 1000 can determine whether the pressure of the cooling gas is within a preset first pressure range (S1441).

[0100] In the first opening operation step, when the pressure of the cooling gas is within a preset first pressure range, the processor 1112 can adjust the opening speed of at least one of the first valve 170, the second valve 570, and the third valve 970. At this time, the processor 1112 can adjust the preset opening speed of at least one of the first valve 170, the second valve 570, and the third valve 970 in accordance with the first pressure range to perform rapid opening, average opening, or delayed opening operation at a preset fine opening level in association with the first pressure range (S1442).

[0101] In the second determination step, the processor 1112 can determine whether the pressure of the cooling gas is a second pressure range that is higher than the preset first pressure range (S1443).

[0102] In the second opening operation step, when the pressure of the cooling gas is within a preset second pressure range, the processor 1112 can adjust the opening speed of at least one of the first valve 170, the second valve 570, and the third valve 970. At this time, the processor 1112 can adjust the preset opening speed of at least one of the first valve 170, the second valve 570, and the third valve 970 in accordance with the second pressure range to perform rapid opening, average opening, or delayed opening operation at a half-open level in association with the second pressure range (S1444).

[0103] In the third determination step, if the pressure of the cooling gas is not within the preset second pressure range, it can be determined to be within the third pressure range by the processor 1112 (S1445).

[0104] In the third opening operation step, if the processor 1112 determines that a third pressure range has been reached, the opening speed of at least one of the first valve 170, the second valve 570, and the third valve 970 can be adjusted. At this time, the processor 1112 can adjust the opening speed of at least one of the first to third valves 170, 570, and 970 in accordance with the third pressure range to perform rapid opening, average opening, or delayed opening operations at a preset fully open level in association with the third pressure range (S1446).

[0105] Furthermore, the valve operation method according to this disclosure may include a first injection step (S1447), a second injection step (S1448), and a third injection step (S1449).

[0106] In the first injection step, when the pressure of the cooling gas is within a preset first pressure range (S1441), the processor 1112 can adjust the opening state of at least one of the preset first injection control unit 180, second injection control unit 580, and third injection control unit 980 in accordance with the first pressure range to inject the cooling gas at a preset first injection amount level in association with the first pressure range (S1447).

[0107] In the second injection step, when the pressure of the cooling gas is in a second pressure range that is higher than the preset first pressure range (S1443), the processor 1112 can adjust the opening state of at least one of the preset first injection control unit 180, second injection control unit 580 and third injection control unit 980 in accordance with the second pressure range to inject the cooling gas at a second injection amount level that is lower than the preset first injection amount level in association with the second pressure range (S1448).

[0108] In the third injection step, when the pressure of the cooling gas is in a third pressure range higher than the preset second pressure range (S1445), the processor 1112 can adjust the opening state of at least one of the preset first injection control unit 180, second injection control unit 580, and third injection control unit 980 in accordance with the third pressure range to inject the cooling gas at a third injection amount level lower than the preset second injection amount level in association with the third pressure range (S1449). Here, the first injection amount level may be higher than the second injection amount level, and the second injection amount level may be higher than the third injection amount level. At this time, the opening state may be at least one of the opening degree and the opening speed.

[0109] This disclosure also allows the processor 1112 to control at least one of the first injection control unit 180, the second injection control unit 580, and the third injection control unit 980 to inject cooling gas intermittently multiple times according to a preset number of times, so as to prevent at least one of the first injection unit 130, the second injection unit 530, and the third injection unit 930 from freezing.

[0110] Figure 16 This is another example illustrating the sequence diagram of the operation method of the valve included in the skin management tip according to the present disclosure.

[0111] Reference Figure 16 The operation method of at least one of the first valve 170, the second valve 570, and the third valve 970 may include a sensing step (S1610), a first determination step (S1620), an injection step (S1630), an injection stop step (S1640), a second determination step (S1650), and an opening operation step (S1660).

[0112] In the sensing step, the temperature of the cooling gas can be sensed by a temperature sensor provided in at least one of the first electrode component 120, the second electrode component 520, and the third electrode component 920 (S1610). At this time, the position of the temperature sensor is not limited to this, and the temperature sensor may also be provided on one side inside at least one of the first housing 110, the second housing 510, and the third housing 910.

[0113] In the first determination step, the processor 1112 can determine whether the temperature of the cooling gas is the preset reference temperature (S1620).

[0114] During the injection step, if the temperature of the cooling gas is not the preset reference temperature ("No" in S1620), the processor 1112 can control the injection nozzle to lower the temperature of the cooling gas to the preset reference temperature (S1630). In this case, the processor 1112 can control the injection nozzle to inject a preset amount of cooling gas in relation to the temperature of the cooling gas. That is, if the temperature of the cooling gas is high, the processor 1112 can control the injection nozzle to inject a large amount of cooling gas.

[0115] In the injection stop step, if the temperature of the cooling gas is a preset reference temperature ("Yes" in S1620), the processor 1112 can control the injection nozzle to stop the injection of cooling gas (S1640).

[0116] In the second determination step, the pressure state of the cooling gas remaining in the containment space of at least one of the first housing 110, the second housing 510, and the third housing 910 when at least one of the first valve 170, the second valve 570, and the third valve 970 is determined by at least one of the first valve 170, the second valve 570, and the third valve 970 when they are pressurized (S1650). At this time, the pressure state can vary depending on the amount of cooling gas injected. For example, if the amount of cooling gas injected is within a preset first injection range, at least one of the first valve 170, the second valve 570, and the third valve 970 can be determined to be in a first pressure state; if the amount of cooling gas injected is within a second injection range greater than the preset first injection range, at least one of the first valve 170, the second valve 570, and the third valve 970 can be determined to be in a second pressure state; and if the amount of cooling gas injected is within a third injection range greater than the preset second injection range, at least one of the first valve 170, the second valve 570, and the third valve 970 can be determined to be in a third pressure state. At this point, the first pressure state can be a low level, the second pressure state can be a middle level, and the third pressure state can be a high level.

[0117] In the opening operation step, if the pressure state reaches a preset target pressure, the opening operation can be performed by at least one of the first valve 170, the second valve 570, and the third valve 970 (S1660). For example, if the first pressure state reaches a preset first target pressure, at least one of the first valve 170, the second valve 570, and the third valve 970 can perform the opening operation with a first condition of at least one of the opening level and opening speed corresponding to a low-level pressure state. As another example, if the second pressure state reaches a second target pressure higher than the preset first target pressure, at least one of the first valve 170, the second valve 570, and the third valve 970 can perform the opening operation with a second condition of at least one of the opening level and opening speed corresponding to an intermediate-level pressure state. Yet another example, if the third pressure state reaches a third target pressure higher than the preset second target pressure, at least one of the first valve 170, the second valve 570, and the third valve 970 can perform the opening operation with a third condition of at least one of the opening level and opening speed corresponding to a high-level pressure state. At this point, the third condition can be set to at least one of a wider opening level and a faster speed than the second condition, and the second condition can be set to at least one of a wider opening level and a faster speed than the first condition.

[0118] Therefore, the operation method of the skin management tip and valve according to the present invention and the handpiece including the method can prevent pain and burns caused by high-frequency electrode heating in advance, can prevent the increase in refrigerant usage costs in advance, and can improve cooling efficiency by keeping the internal temperature low.

Furthermore, those skilled in the art will readily understand that the relative positions of the constituent elements can be altered to correspond to the performance or structure of the system.
