[0078] Memory 1111 contains data that supports the various functions of this device, controllerIn addition to storing programs for the device's operation, it can also store input and output data, including numerous application programs (or applications) driven by the device, data for the device's operation, and instruction words. At least some of these application programs can be downloaded from an external server via wireless communication.

[0079] Such memory 1111 may include at least one type of storage medium from among flash memory type, hard disk type, SSD type (Solid State Disk type), SDD type (Silicon Disk Drive type), multimedia card micro type, card type memory (e.g., SD or XD memory), random access memory (RAM), static random access memory (SRAM), read-only memory (ROM), EEPROM (electrically erasable programmable read-only memory), PROM (programmable read-only memory), magnetic memory, magnetic disk, and optical disk. Furthermore, memory 1111 can also function as a database, separate from the device but connected via wired or wireless means.

[0080] The processor 1112 can also adjust the opening speed of at least one of the first to third valves 170, 570, and 970, which are already set in accordance with the first pressure range, so as to perform a fast opening, an average opening, or a delayed opening operation to a fine opening level that has already been set in conjunction with the first pressure range.

[0081] The processor 1112 can also adjust the opening speed of at least one of the first to third valves 170, 570, and 970 if the cooling gas pressure is in a second pressure range higher than a first pressure range already set. In this case, the processor 1112 can adjust the opening speed of at least one of the first to third valves 170, 570, and 970, which have been set in accordance with the second pressure range, to perform a fast opening, an average opening, or a delayed opening operation to a semi-open level already set in conjunction with the second pressure range.

[0082] The processor 1112 can also adjust the opening speed of at least one of the first to third valves 170, 570, and 970 if the cooling gas pressure is in a third pressure range higher than a second pressure range that has already been set. In this case, the processor 1112 can adjust the opening speed of at least one of the first to third valves 170, 570, and 970 that have already been set in accordance with the third pressure range to perform a fast opening, an average opening, or a delayed opening operation to a fully open level that has already been set in conjunction with the third pressure range.

[0083] The first to third injections of the skin management tips 100, 500, and 900 relating to this disclosure controller At least one of 180, 580, and 980 is one of the first to third syringe It is installed in at least one of the 130, 530, and 930, and the amount of cooling gas injected can be controlled according to the pressure of the cooling gas. In this case, the first to third injection controller At least one of 180, 580, and 980 is one of the first to third syringe It is provided as a fourth valve inside at least one of 130, 530, and 930. For example, the fourth valve may be a check valve, but is not limited to a solenoid valve. In another example, the fourth solenoid valve may be provided with both a check valve and a solenoid valve.

[0084] Here, the processor 1112 injects first to third gases according to the pressure of the cooling gas. controllerThe amount of cooling gas injected can be controlled by controlling at least one of 180, 580, and 980. For example, if the cooling gas pressure is within a first pressure range that has already been set, the processor 1112 controls the first to third injection levels that have already been set in conjunction with the first pressure range so that the cooling gas is injected to a level that has already been set in conjunction with the first pressure range. controller At least one of the open states 180, 580, and 980 can be adjusted. As another example, if the cooling gas pressure is in a second pressure range that is higher than a first pressure range that has already been set, the processor 1112 will inject the cooling gas to a second injection level that is lower than a first injection level that has already been set in conjunction with the second pressure range. controller At least one of the open states 180, 580, and 980 can be adjusted. As yet another example, if the cooling gas pressure is in a third pressure range that is higher than a second pressure range that has already been set, the processor 1112 will inject the cooling gas to a third injection level that is lower than a second injection level that has already been set in conjunction with the third pressure range. controller At least one of the following opening states can be adjusted: 180, 580, and 980. Here, the level of the first injection volume may be higher than the level of the second injection volume, and the level of the second injection volume may be higher than the level of the third injection volume. In this case, the opening state can be at least one of the degree of opening and the rate of opening.

[0085] Figures 14 and 15 are flowcharts illustrating an example of the operation method of a valve included in the skin management chip according to this disclosure. Referring to Figure 14, at least one operation method of the first to third valves 170, 570, and 970 may include a sensing stage (S1410), a judgment stage (S1420), a maintenance stage (S1430), and an opening stage (S1440).

[0086] The sensing stage allows at least one of the first to third valves 170, 570, and 970 to sense the pressure of the cooling gas injected through the refrigerant transmission paths (A11-A18) (A21-A29) (A31-A42) of the skin management tips 100, 500, and 900 (S1410).

[0087] The determination stage allows for the determination of whether the cooling gas pressure has reached a previously set reference pressure by at least one of the first to third valves 170, 570, and 970 (S1420).

[0088] In the maintenance phase, if the cooling gas pressure does not reach an already set reference pressure by at least one of the first to third valves 170, 570, and 970, the closing operation can be maintained (S1430).

[0089] In the opening operation phase, if the cooling gas pressure reaches the reference pressure, the valve can be opened to a previously set opening level for each pressure range by at least one of the first to third valves 170, 570, and 970 (S1440).

[0090] For example, at least one of the first to third valves 170, 570, and 970 can be opened to a pre-set fine opening level in conjunction with the first pressure range if the cooling gas pressure is already within the first pressure range. In this case, the first pressure range may be a low-level pressure range.

[0091] As another example, at least one of the first to third valves 170, 570, and 970 can be opened to a pre-set semi-open level in conjunction with the second pressure range if the cooling gas pressure is in a second pressure range that is higher than the already set first pressure range. In this case, the second pressure range may be an intermediate level pressure range.

[0092] As a further example, at least one of the first to third valves 170, 570, and 970 can be opened to a pre-set fully open level in conjunction with the third pressure range if the cooling gas pressure is in a third pressure range that is higher than a pre-set second pressure range. In this case, the third pressure range may be a high-level pressure range.

[0093] Referring to Figure 15, the valve operation method may also include a first decision stage (S1441), a first opening operation stage (S1442), a second decision stage (S1443), a second opening operation stage (S1444), a third decision stage (S1445), and a third opening operation stage (S1446).

[0094] The first determination stage allows the handpiece 1000, via its processor 1112, to determine whether the cooling gas pressure is within a previously set first pressure range (S1441).

[0095] In the first opening operation stage, the processor 1112 can adjust the opening speed of at least one of the first to third valves 170, 570, and 970 if the cooling gas pressure is within a pre-set first pressure range. 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, which have been set in accordance with the first pressure range, to perform a fast opening, an average opening, or a delayed opening operation to a pre-set fine opening level in conjunction with the first pressure range (S1442).

[0096] The second decision stage, via the processor 1112, can determine whether the cooling gas pressure is in a second pressure range that is higher than the already set first pressure range (S1443).

[0097] In the second opening operation stage, the processor 1112 can adjust the opening speed of at least one of the first to third valves 170, 570, and 970 if the cooling gas pressure is within the already set second pressure range. 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, which have been set in accordance with the second pressure range, so as to perform a fast opening, an average opening, or a delayed opening operation to a semi-open level that has been set in conjunction with the second pressure range (S1444).

[0098] In the third decision stage, if the cooling gas pressure is not within the already set second pressure range, it can be determined via the processor 1112 to be within the third pressure range (S1445).

[0099] In the third opening operation stage, if it is determined via the processor 1112 that the pressure is within the third pressure range, the opening speed of at least one of the first to third valves 170, 570, and 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, which have already been set in accordance with the third pressure range, so as to perform a fast opening, an average opening, or a delayed opening operation to a fully open level that has already been set in conjunction with the third pressure range (S1446).

[0100] Furthermore, the valve operation method according to this disclosure may include a first injection stage (S1447), a second injection stage (S1448), and a third injection stage (S1449).

[0101] The first injection step involves, via the processor 1112, if the pressure of the cooling gas is already within a set first pressure range (S1441), injecting the cooling gas to a level of a first injection amount already set in conjunction with the first pressure range, by performing the first to third injections that have been set in conjunction with the first pressure range. controller At least one of the open states among 180, 580, and 980 can be adjusted (S1447).

[0102] In the second injection stage, if the cooling gas pressure is in a second pressure range higher than the already set first pressure range (S1443), the first to third injections, which have been set in accordance with the second pressure range, are performed via the processor 1112 so that the cooling gas is injected to a second injection volume level lower than the first injection volume level which has been set in conjunction with the second pressure range. controller At least one of the open states among 180, 580, and 980 can be adjusted (S1448).

[0103] In the third injection stage, if the cooling gas pressure is in a third pressure range higher than the already set second pressure range (S1445), the cooling gas is injected to a third injection volume level lower than the already set second injection volume level in conjunction with the third pressure range, via the processor 1112. controller At least one of the opening states among 180, 580, and 980 can be adjusted (S1449). Here, the level of the first injection volume may be higher than the level of the second injection volume, and the level of the second injection volume may be higher than the level of the third injection volume. In this case, the opening state may be at least one of the degree of opening and the speed of opening.

[0104] This disclosure describes injecting cooling gas in multiple steps via the processor 1112, at a predetermined number of times, and first to third syringe Inject the first to third doses so that at least one of 130, 530, or 930 does not freeze. controller You can also control at least one of 180, 580, or 980.

[0105] Figure 16 is a flowchart illustrating, as another example, the operation method of a valve included in the skin care chip according to this disclosure.

[0106] Referring to Figure 16, at least one of the first to third valves 170, 570, and 970 may include a sensing stage (S1610), a first judgment stage (S1620), an injection stage (S1630), an injection stop stage (S1640), a second judgment stage (S1650), and an opening stage (S1660).

[0107] In the sensing stage, the temperature of the cooling gas can be sensed via a temperature sensor provided on at least one of the first to third electrode members 120, 520, and 920 (S1610). At this time, the position of the temperature sensor is not limited to this, and it can also be provided on one side inside at least one of the first to third housings 110, 510, and 910.

[0108] The first decision stage allows the processor 1112 to determine whether the cooling gas temperature is already at a set reference temperature (S1620).

[0109] In the injection phase, if the temperature of the cooling gas is not already at a set reference temperature (no in S1620), the processor 1112 can control the injection nozzles to inject the cooling gas so that the temperature of the cooling gas drops to the already set reference temperature (S1630). At this time, the processor 1112 can control the injection nozzles to inject the cooling gas in a coordinated manner according to the temperature of the cooling gas, as previously set. In other words, the processor 1112 can control the injection nozzles to inject more cooling gas when the temperature of the cooling gas is high.

[0110] In the injection termination phase, the injection nozzle can be controlled via the processor 1112 to terminate the injection of cooling gas if the temperature of the cooling gas has already reached a set reference temperature ("yes" in S1620) (S1640).

[0111] In the second determination stage, at least one of the first to third valves 170, 570, and 970 can determine the pressure state generated when the cooling gas remaining in the containment space of at least one of the first to third housings 110, 510, and 910 pressurizes at least one of the first to third valves 170, 570, and 970 (S1650). At this time, the pressure state may change depending on the amount of cooling gas injected. For example, at least one of the first to third valves 170, 570, and 970 can determine that it is in a first pressure state if the amount of cooling gas injected is within the range of a first injection amount that has already been set, in a second pressure state if it is within the range of a second injection amount that is greater than the range of a first injection amount that has already been set, and in a third pressure state if it is within the range of a third injection amount that is greater than the range of a second injection amount that has already been set. In this case, the first pressure state may be a low-level pressure state, the second pressure state may be an intermediate-level pressure state, and the third pressure state may be a high-level pressure state.

[0112] The opening operation phase allows at least one of the first to third valves 170, 570, and 970 to open when the pressure state reaches a previously set target pressure (S1660). For example, at least one of the first to third valves 170, 570, and 970 can open when the first pressure state reaches a previously set first target pressure, under at least one first condition of opening level and opening speed corresponding to a low pressure state. As another example, at least one of the first to third valves 170, 570, and 970 can open when the second pressure state reaches a second target pressure higher than the previously set first target pressure, under at least one second condition of opening level and opening speed corresponding to an intermediate pressure state. As yet another example, at least one of the first to third valves 170, 570, and 970 can be opened under at least one third condition, which is an opening level and opening speed corresponding to the high pressure state, when the third pressure state reaches a third target pressure higher than the already set second target pressure. In this case, 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.
