The present disclosure relates to a cooling system for performing cooling and a cooling apparatus using the same, and more particularly, to a cooling apparatus and a cooling method thereof, in which a filter fixing module that is easily removed therefrom is used, thereby safely cooling a target.

According to the embodiments of the present specification, the cooling system may be used to cool the target so that the target is in a cooled state for aesthetic or therapeutic purposes of the target, in which case a cooling control method may be used so that the target is not damaged by supercooling or the like.

The target may refer to a target that is cooled using a cooling system. For example, the target may refer to a target that receives cosmetic treatment of the skin using cooling. In particular, the target may comprise a body part that can be removed by cooling a local area, including moles, warts, corns, acne scars, etc., or may comprise a body part that requires local anesthesia during laser treatment (e.g., dehairing, peeling, or botulinum treatment). As another example, a target may refer to a target that enters an anesthetized or painless state for receiving a medical procedure. In particular, the target may refer to body parts including nerves, such as diseased eyes, skin, and gums.

Cooling refers to absorbing thermal energy of an object to be cooled by applying cooling energy to the object to be cooled, thereby lowering the temperature of the object to be cooled. Here, the cooling energy means heat dissipation through cooling, and can be understood to mean a concept of heat energy reduction. For example, cooling is the application of cooling energy to a target to be cooled by "spraying" a refrigerant or air gas onto the target to be cooled. For another example, cooling is the application of cooling energy to a target to be cooled by applying cooling energy to a cooling medium and causing the cooling medium to "contact" the target to be cooled. In other words, cooling should be understood as a comprehensive concept including various methods of applying cooling energy to an object to be cooled. Hereinafter, for convenience of explanation, the cooling target by the non-contact method using the refrigerant is described as a main embodiment, but the technical idea of the present specification is not limited thereto.

The cooling system may also be used for treatment such as to relieve inflammation (e.g., to relieve acne), relieve itching, treat pigmentary lesions, treat vascular lesions, remove plaque and remove lipid. Alternatively, the cooling system may cool the target to directly destroy at least a portion of the target. For example, when the target is a body part including the above-mentioned skin nevi, warts, corns, etc., the cooling system supplies cooling energy to the target through the surface of the target so that tissues in the target can be necrotized or killed by the supplied cooling energy. For another example, the cooling system supplies cooling energy to the target surface by spraying a refrigerant on the target surface, and the supplied cooling energy makes the temperature of the nerves distributed under the target surface lower than the temperature at which the nerves are temporarily paralyzed or nerve transmission is blocked, whereby the target can be in an anesthetized or analgesic state. The cooling system may cool the target surface and the target interior to an appropriate temperature range in order to maintain such anesthesia or analgesia for a predetermined time.

Hereinafter, for convenience of explanation, a case where the target is skin and the cooling system sprays a refrigerant on the skin surface to deliver cooling energy to the skin is described as a main embodiment, but the technical ideas of the present specification are not limited thereto, but may be applied to any part of the body.

Hereinafter, a cooling system 10 according to an embodiment of the present specification will be described with reference to fig. 1 to 4.

Fig. 1 is a view showing a cooling system 10 according to an embodiment of the present specification. Referring to fig. 1, the cooling system 10 may include a cooling device 1000, a filter fixing module 2000, and a bracket 3000.

The cooling device 1000 may provide cooling energy to the target to cool the target. Specifically, as described later, the cooling device 1000 may control the temperature of the refrigerant flowing through the flow path in the cooling device, and may cool the target by delivering the refrigerant having the target temperature to the target.

The cooling device 1000 may be coupled with the filter fixing module 2000, and may filter out impurities contained in the refrigerant introduced from the refrigerant supply unit 4000. Further, the cooling device 1000 may cool the object with the refrigerant filtered of impurities. Thus, the cooling system 10 according to the embodiment of the present application can safely cool the target so that the target is not contaminated or infected.

The cooling device 1000 may be mounted on the stand 3000 after or during use. For example, the cooling device 1000 may be mounted on the stand 3000 in a closed state. For another example, the cooling device 1000 may be mounted on the stand 3000 while being supplied with electricity according to the convenience of the user.

The cooling device 1000 may be implemented as a portable device with a case attached so that a user can easily carry the device, or as a hand piece attached to a large device such as a refrigerant tank.

The cooling device 1000 may be mounted to the stand 3000. Specifically, the stand 3000 is designed to have a structure corresponding to the cooling device 1000, so that a user can mount the cooling device 1000 on the stand 3000 during or after using the cooling device 1000.

As described later, the stand 3000 may include a temperature measurement region in which a temperature may be measured to determine whether the sensor module 1400 of the cooling device 1000 is operating normally, and may have a shape to protect the cooling device 1000 from external impact. The temperature measurement region of the stand 3000 will be described in detail in fig. 20.

Meanwhile, in the cooling system 10 disclosed in the present specification, the bracket 3000 may be omitted.

Fig. 2-3 are views of a cooling system 10 according to embodiments of the present description. Referring to fig. 2 and 3, the cooling system 10 may include a cooling device 1000, a filter fixing module 2000, a bracket 3000, and a refrigerant supply unit 4000.

The refrigerant supply unit 4000 may have a form of a cartridge. In this case, the cartridge may be perforated by the perforated member of the filter fixing module so that the refrigerant received in the cartridge may be supplied to the cooling device.

The refrigerant supply unit 4000 may be configured as a cartridge including a plurality of materials or as a plurality of cartridges to deliver substances other than the refrigerant to the target area.

Alternatively, the refrigerant supply unit 4000 may have a form of a refrigerant tank. In this case, the refrigerant tank may be connected to a hose so as to supply the refrigerant to the cooling device 1000. In this case, the hose may be screwed to the connection member of the cooling device 1000 so that the refrigerant received in the refrigerant tank may be supplied to the cooling device 1000.

Further, when the refrigerant supply unit 4000 has the shape of a refrigerant tank, the refrigerant tank and the hose may be interpreted to mean the refrigerant supply unit 4000.

Meanwhile, when the cooling device 1000 is connected to the refrigerant tank through a hose, the perforated member 2200 of the filter fixing module 2000 may be omitted.

Meanwhile, in order to convey materials other than the refrigerant to the target area, the refrigerant supply unit 4000 may have a plurality of materials included in the refrigerant tank, or may have a plurality of refrigerant tanks.

Fig. 4 is a block diagram showing the configuration of a cooling device 1000, a filter fixing module 2000, and a refrigerant supply unit 4000 according to an embodiment of the present specification.

Referring to fig. 4, the cooling apparatus 1000 may include a refrigerant flow control unit 1100, a refrigerant temperature control unit 1200, a nozzle unit 1300, a sensor module 1400, an input module 1500, an output module 1600, a control module 1700, and a connection unit 1800.

Hereinafter, each component will be described in detail.

According to an embodiment of the present application, the refrigerant flow control unit 1100 may include a valve. The valve may be used to control the flow and velocity of the refrigerant. The valve may be used to vent or prevent refrigerant from passing through the valve. Alternatively, the valve may be used to control the degree of discharge of refrigerant through the valve.

Valves according to embodiments of the present application may be controlled based on specific signals. The valve may open and close in response to an electronic signal generated by the control module 1700. For a specific example, the valve may be an electronic valve (e.g., solenoid valve), but is not limited thereto.

Valves according to embodiments of the present application may be controlled based on mechanical structure and fluid movement. The valve may open and close according to the pressure created by the fluid moving along the flow path in the cooling device 1000. For a specific example, the valve may be a hydraulic valve (e.g., a pressure control valve), but is not limited thereto.

Valves according to embodiments of the present application may be controlled based on user input. The user can open or close the valve. For a specific example, the valve may be a manual valve (e.g., a shut-off valve), but is not limited thereto.

For example, a valve included in the refrigerant flow control unit 1100 may be located between an inlet (or referred to as an introduction opening) of the cooling device 1000 and the nozzle unit 1300. In this case, the refrigerant flow control unit 1100 may control the amount of the refrigerant supplied from the inlet of the cooling device 1000 to the nozzle unit 1300.

For example, a valve may be located between the inlet of the cooling device 1000 and the nozzle unit 1300, and the amount of refrigerant supplied from the inlet of the cooling device 1000 to the nozzle unit 1300 may be controlled. Specifically, in the open state of the valve, the refrigerant may move from the inlet of the cooling device 1000 to the nozzle unit 1300, and in the closed state of the valve, the refrigerant may be restricted from moving from the inlet of the cooling device 1000 to the nozzle unit 1300. Further, the opening time or the opening period of the valve may be controlled to control the amount of refrigerant that may move from the inlet of the cooling device 1000 to the nozzle unit 1300.

For example, a valve may be located between an inlet of the cooling device 1000 in the connection unit 1800 of the cooling device 1000 and the refrigerant temperature control unit 1200 to control the amount of refrigerant supplied from the inlet of the cooling device 1000 to the refrigerant temperature control unit 1200. Specifically, in the open state of the valve, the refrigerant may be in a state capable of moving from the inlet of the cooling device 1000 to the refrigerant temperature control unit 1200, but in the closed state of the valve, the refrigerant may be in a state restricted from moving from the inlet of the cooling device 1000 to the refrigerant temperature control unit 1200. Further, the opening time or the opening period of the valve may be controlled so that the amount of the refrigerant moving from the inlet of the cooling device 1000 to the refrigerant temperature control unit 1200 may be controlled.

As another example, the refrigerant flow control unit 1100 may be located between the refrigerant temperature control unit 1200 and the nozzle unit 1300 in the cooling device 1000. In this case, the refrigerant flow control unit 1100 may control the amount of the refrigerant supplied from the refrigerant temperature control unit 1200 to the nozzle unit 1300. For example, a valve may be located between the refrigerant temperature control unit 1200 and the nozzle unit 1300, and the amount of refrigerant supplied from the refrigerant temperature control unit 1200 to the nozzle unit 1300 may be controlled. Specifically, in the open state of the valve, the refrigerant may be in a state capable of moving from the refrigerant temperature control unit 1200 to the nozzle unit 1300, but in the closed state of the valve, the refrigerant may be in a state restricted from moving from the refrigerant temperature control unit 1200 to the nozzle unit 1300. Further, an opening period or an opening cycle of the valve may be controlled, so that an amount of refrigerant that can move from the refrigerant temperature control unit 1200 to the nozzle unit 1300 may be controlled. In other words, the opening period of the refrigerant temperature control unit 1200 is controlled so that the amount of refrigerant supplied to the nozzle unit 1300 can be controlled, and the amount of refrigerant to be finally sprayed can be controlled, thereby controlling the temperature of the skin surface.

For example, the refrigerant flow control unit 1100 may be implemented as a solenoid valve electrically connected to the control module 1700 and the input module 1500, and a signal generated when the user manipulates the input module 1500 is input to the control module 1700, based on which the control module 1700 controls the solenoid valve to be opened, so that inflow or outflow of refrigerant may be controlled.

For example, the refrigerant flow control unit 1100 may be implemented as a solenoid valve. In this case, the solenoid valve may control an open period of the valve by a Pulse Width Modulation (PWM) method according to an electric signal of the control module 1700, thereby controlling inflow or outflow of the refrigerant. Specifically, the solenoid valve automatically performs a plurality of opening and closing operations according to a protocol preset from the control module 1700 such that the valve may be opened only for a predetermined time during the operation. In this case, the opening period of the valve may be a regular period or an irregular period.

Referring again to fig. 4, the cooling apparatus 1000 may include a refrigerant temperature control unit 1200. The refrigerant temperature control unit 1200 according to the embodiment of the present application may perform a function of controlling the physical state of the refrigerant. In other words, the refrigerant temperature control unit 1200 may perform a function of controlling the physical state of the refrigerant inside the cooling device 1000. That is, the refrigerant temperature control unit 1200 may perform a function of controlling the physical state of the refrigerant moving in the cooling device 1000.

For example, the refrigerant temperature control unit 1200 may control the temperature of the refrigerant. The refrigerant temperature control unit 1200 may heat the refrigerant. Alternatively, the refrigerant temperature control unit 1200 may cool the refrigerant. Alternatively, the refrigerant temperature control unit 1200 may maintain the temperature of the refrigerant by heating and/or cooling the refrigerant according to the state of the refrigerant.

For example, the refrigerant temperature control unit 1200 may be disposed between the refrigerant flow control unit 1100 and the nozzle unit 1300. For example, the refrigerant temperature control unit 1200 may be disposed between the refrigerant flow control unit 1100 and the connection unit 1800. However, in order to maintain the temperature of the target at a predetermined temperature by injecting the refrigerant toward the target, the refrigerant temperature control unit 1200 may be more advantageously disposed between the refrigerant flow control unit 1100 and the nozzle unit 1300.

The refrigerant temperature control unit 1200 according to the embodiment of the present application may include a temperature control member capable of generating heat energy.

The temperature control member may be implemented in various forms.

For example, the temperature control member may include a thermocouple using the peltier effect that receives an electric current to absorb heat on the first surface and releases heat on the second surface depending on the direction of the received electric current. In the case where the refrigerant temperature control unit 1200 includes a thermocouple, when an electric current is applied to the thermocouple, the first surface of the thermocouple may generate heat energy and the second surface of the thermocouple may generate cooling energy due to the peltier effect.

According to an embodiment of the present application, the cooling device 1000 disposed in thermal contact with the flow path in which the refrigerant flows may be disposed on a surface corresponding to the first surface of the thermocouple. In this case, a thermocouple may be used as the refrigerant temperature control unit 1200.

The refrigerant temperature control unit 1200 may generate heat energy using chemical energy or electric energy. In addition, the refrigerant temperature control unit 1200 may generate heat energy by a joule-thomson method using condensed gas.

For example, the temperature control means may comprise a device or element using a thermodynamic cycle, such as a Stirling cooler or a vapor compression refrigeration cycle, or a Joule-Thomson process using an expanding gas.

For another example, the temperature control member may generate or provide cooling energy by using a refrigerant (e.g., carbon dioxide or liquid nitrogen).

The temperature control member may be thermally coupled to a flow path through which the refrigerant in the cooling device 1000 flows. For example, the temperature control member may be in contact with at least a portion of the surface of the flow path through which the refrigerant flows to provide cooling or thermal energy thereto.

Hereinafter, for convenience of explanation, a case where the temperature control member is a thermocouple using the peltier effect is mainly described, but the technical idea of the present specification is not limited thereto.

Referring again to fig. 4, the cooling apparatus 1000 according to an embodiment of the present application may include a nozzle unit 1300. In this case, the nozzle unit 1300 may perform a function of spraying the refrigerant flowing in the cooling device 1000 to the outside. The nozzle unit 1300 may perform a function of discharging the refrigerant passing through the refrigerant flow control unit 1100 and/or the refrigerant temperature control unit 1200 to the outside.

The nozzle unit 1300 according to embodiments of the present application may be implemented as any suitable type of nozzle. The nozzle may be used to spray the refrigerant such that the refrigerant flowing in at least one region inside the cooling device 1000 is discharged to the free space to reach a target region of the skin surface. Furthermore, the nozzle unit 1300 may be implemented to include a nozzle structure capable of optimizing the joule-thomson effect. Specifically, the nozzle unit is formed as a nozzle having a width narrower than a flow path in which the high-pressure refrigerant flows. When the flow path is opened, high-pressure refrigerant is guided to the nozzle along the flow path, and the refrigerant discharged through the nozzle is injected in a cooled state by the joule-thomson effect.

The refrigerant injected through the nozzle unit 1300 may be injected in a cooled state by the joule-thomson effect. Here, the joule-thomson effect is a phenomenon in which the temperature of the compressed gas decreases when the gas expands. The joule-thomson effect represents a temperature change associated with a thermodynamic phase consisting of pressure and temperature, and is a phenomenon applied to liquefied air or to cool air by a refrigerant. When an orifice, such as a syringe, is inserted into the flow path of the fluid, the temperature of the fluid behind the orifice decreases. The joule-thomson effect is a phenomenon in which the internal energy is hardly changed during the free expansion of the gas, i.e., during adiabatic expansion of the gas without exchanging work with the outside, and refers to an effect in which the gas is adiabatically free expanded by a gas liquefying device to obtain a low temperature. When the joule-thomson effect is utilized, the refrigerant sprayed through the nozzle unit 1300 is cooled due to a sudden pressure drop and sprayed to the region to be treated, the refrigerant may contact the region to be treated, and may take away heat of the region to be treated, so that the region to be treated may be cooled.

Furthermore, the nozzle may have wear resistance. In other words, the nozzle may be formed of a material that is not easily damaged by friction. For example, the nozzle may be made of an aluminum alloy, a steel alloy, stainless steel, or a copper alloy, but is not limited thereto.

Further, according to an embodiment of the present application, the nozzle unit 1300 may include a guide unit 1310 such that the refrigerant discharged from the nozzle unit 1300 is limited to a target area on the skin surface.

Meanwhile, the guide unit 1310 may have a form in which the refrigerant discharged from the nozzle unit 1300 and flowing laterally after reaching the target area in the form of the impact jet may be restricted in a predetermined area. For example, the surface contacting the target area of the guide unit 1310 may have a circular or polygonal shape, or a circular or polygonal shape with discrete points.

In this case, the guide unit 1310 may control the temperature of the target area by restricting the refrigerant in the predetermined area, and after cooling the target area, the refrigerant may be discharged to the outside through the hole provided at the rear side.

Referring again to fig. 4, a cooling device 1000 according to an embodiment of the present application may include a sensor module 1400. The sensor module 1400 may detect the temperature of a target area of the skin surface and/or physical characteristics of the cooling device 1000.

For example, the sensor module 1400 may detect the temperature of the target region. For example, the sensor module 1400 may include at least one temperature sensor 1410 or 1420, and the at least one temperature sensor 1410 or 1420 may measure the temperature of a target area of the skin surface. At least one temperature sensor 1410 or 1420 of the sensor module 1400 may be composed of a non-contact temperature sensor using infrared light and a contact temperature sensor such as a thermocouple, a Resistance Temperature Detector (RTD), a thermistor, an IC temperature sensor, or an ultrasonic temperature sensor.

For another example, the sensor module 1400 may detect physical characteristics of components included in the cooling device 1000. For example, the sensor module 1400 may measure an electrical characteristic, such as a current or voltage applied to the refrigerant temperature control unit 1200. In this case, the sensor module 1400 may include analog or electronic circuits for measuring electrical characteristics such as current or voltage.

The sensor module 1400 may provide the detected temperature of the target area and/or the physical characteristics of the cooling device 1000 to the control module 1700. For example, the sensor module 1400 may provide signals to the control module 1700 that indicate a real-time temperature value of the target area and a current or voltage value applied to the refrigerant temperature control unit 1200.

The input module 1500 may receive user input from a user. The user's input may be performed in various forms including button input, key input, touch input, rotation input, or voice input. For example, the input module 1500 includes buttons that a user can press, a scroll wheel switch that a user can turn, a touch sensor that detects a user touch, a microphone that receives user voice input, and various types of input means that detect or receive user input.

The output module 1600 may output various information and provide the information to a user. The output module 1600 includes a cooling state of the cooling device, a display that outputs information related to the real-time temperature of the target area, a speaker that outputs sound, a haptic device that generates vibration, and various other types of output means.

The control module 1700 may control the overall operation of the cooling device 1000. For example, the control module 1700 may load and execute programs for operation of the refrigerant flow control unit 1100. For another example, the control module 1700 may control the amount of current (or voltage) applied to the refrigerant temperature control unit 1200 to control the thermal energy transferred to the refrigerant, may control the input module 1500 and the output module 1600 to generate and transmit control signals according to user inputs, or may provide specific information to the user.

Here, the control module 1700 may be implemented as a device, such as a Central Processing Unit (CPU), microprocessor, processor core, multiprocessor, application Specific Integrated Circuit (ASIC), and Field Programmable Gate Array (FPGA), according to hardware or software, or a combination thereof. The control module 1700 may be provided in the form of an electronic circuit that performs a control function by processing an electrical signal in hardware, and may be provided in the form of a program or code that drives a hardware circuit in software.

Meanwhile, although not shown in fig. 4, the cooling apparatus 1000 may further include a memory storing a control program loaded or executed in the control module 1700, and a power supply unit supplying power required for the operation of the cooling apparatus 1000.

A connection unit 1800 may be provided to connect the refrigerant supply unit 4000 to the cooling device 1000.

In particular, the connection unit 1800 may include at least a portion of the refrigerant supply unit 4000 and/or a housing 1820 for receiving the filter fixing module 2000.

In addition, the connection unit 1800 may include a coupling member 1840 for mounting the refrigerant supply unit 4000 and/or the filter fixing module 2000.

For example, coupling member 1840 may be provided as a structure including threads. For example, coupling member 1840 may be a member including threads consisting of crests and roots. Here, the screw thread of the coupling member 1840 is engaged with the screw thread of the refrigerant supply unit 4000, so that the refrigerant supply unit 4000 can be connected to the cooling device 1000.

For example, coupling member 1840 may include a threaded structure including at least one groove. For example, a filter fixing module 2000, which will be described later, may be provided between the connection unit 1800 of the cooling device 1000 and the refrigerant supply unit 4000. The filter fixing module 2000 may include the grip unit 2300, and the screw thread of the coupling member 1840 may include a groove formed in a shape corresponding to that of the grip unit.

In this case, the refrigerant supply unit 4000 may be perforated by the perforated member 2200 of the filter fixing module 2000, and the grip unit 2300 of the filter fixing module 2000 may be fitted into the groove of the coupling member 1840. With this connection structure, the refrigerant discharged from the refrigerant supply unit 4000 may be introduced into the cooling device 1000 through the connection unit 1800.

With the structure of the connection unit 1800 described above, the filter fixing module 2000 according to the embodiment of the present specification may be received in the coupling member 1840 of the connection unit 1800, and the refrigerant supply unit 4000 may be screwed onto the coupling member 1840 of the connection unit 1800 and may be perforated by the filter fixing module 2000. Thus, according to an embodiment of the present specification, the filter fixing module 2000 may be used to perforate the refrigerant supply unit 4000, and may be used to allow the filter to be received in a path of refrigerant flow. Further, in order to facilitate the use of the filter fixing module 2000, the filter fixing module 2000 may include a grip unit 2300 protruding to the outside of the connection unit 1800, and thus, a user may easily install the filter fixing module 2000 to the cooling device 1000 or may easily remove the filter fixing module 2000 from the cooling device 1000. This will be described in more detail later with reference to fig. 9 to 18.

The filter fixing module 2000 may include a body 2100, a perforated member 2200, a grip unit 2300, and a sealing member 2400.

The body 2100 may have a support surface that supports a filter. Further, the body 2100 may have a receiving surface that receives at least a portion of the filter and sealing member and is connected to the support surface. The body 2100 may be formed in various structures to position the filter in the filter fixing module 2000.

Further, the filter fixing module 2000 may be located between the refrigerant supply unit 4000 and the cooling device 1000, and the filter may be located in a path in which the refrigerant discharged from the refrigerant supply unit 4000 is introduced into an inlet of the cooling device 1000. Accordingly, after impurities contained in the refrigerant are removed by the filter fixing module 2000, the refrigerant may be introduced into the cooling device 1000. Accordingly, the cooling system 10 according to the embodiment of the present application may be provided to minimize the possibility of the target area being contaminated with impurities contained in the refrigerant.

The perforated member 2200 may have a body in which a hollow hole is formed so that the perforated member 2200 performs a function of a flow path of the refrigerant discharged from the refrigerant supply unit 4000. The perforated member 2200 may have a first end adjacent to the support surface of the body 2100, a second end penetrating the refrigerant discharge hole of the refrigerant supply unit 4000, and a body extending from the first end to the second end. In this case, the perforated member 2200 may receive the refrigerant from the refrigerant supply unit 4000 through the second end portion, and the refrigerant may be discharged toward the cooling device 1000 through the first end portion.

The grip unit 2300 may include at least one grip member 2310 or 2320. At least one gripping member 2310 or 2320 may fit into at least one groove included in the threads of coupling member 1840.

For example, the grip unit 2300 may include two grip members 2310 and 2320. In this case, the threads of coupling member 1840 may include two fluted members, and two gripping members 2310 and 2320 may be received in the two fluted members included in the threads, respectively.

For example, the grip unit 2300 may include four grip members. In this case, the threads of the coupling member 1840 may include four grooved members, and four gripping members may be received in the four grooved members included in the threads, respectively.

In this case, each of the gripping members and the threaded fluted member of the coupling member 1840 described above may be formed in a symmetrical structure with respect to the central axis. Alternatively, the threaded fluted member of each gripping member and coupling member 1840 described above may be formed in an asymmetric configuration with respect to the central axis.

With the above structure, the filter fixing module 2000 can be mounted to the connection unit 1800 of the cooling device 1000.

However, the above-described structure is only an example, and the grip unit 2300 may be provided in various structures that can be connected to the coupling member 1840.

In a state where the at least one grip member 2310 or 2320 is mounted to the connection unit 1800 of the cooling device 1000, the at least one grip member 2310 or 2320 may be provided to protrude to the outside of the cooling device 1000. Accordingly, a user may easily apply a force to the at least one gripping member 2310 or 2320 protruding outside the cooling device 1000, and may easily remove the at least one gripping member 2310 or 2320 from the fluted member formed in the threads of the coupling member 1840. For example, when a user applies a force in a direction in which each of gripping members 2310 and 2320 approach each other, gripping members 2310 and 2320, respectively, may be removed from the fluted member formed in the threads of coupling member 1840.

Due to the above-described structure, after the use of the refrigerant supply unit 4000 (e.g., a cartridge or a refrigerant tank) is completed, a user can apply a force to at least one grip member 2310 or 2320, and can easily remove the filter fixing module 2000 from the cooling device 1000.

Meanwhile, when the use of the refrigerant supply unit 4000 (e.g., a cartridge or a refrigerant tank) is completed, gaseous refrigerant may remain in the refrigerant supply unit. When the gaseous refrigerant is exposed to atmospheric pressure, the gaseous refrigerant may be instantaneously expanded and noise is generated, thereby possibly causing inconvenience to the user.

According to the cooling system 10 of the embodiment of the present application, as described above, when the use of the refrigerant supply unit 4000 is completed, the user can remove the refrigerant supply unit 4000 from the coupling member 1840. For example, the user may rotate the refrigerant supply unit 4000 having a box shape in one direction such that the engagement of the threads of the box with the threads of the coupling member 1840 is released. In this case, when the refrigerant supply unit 4000 is removed from the coupling member 1840, a fluid passage may be formed inside the coupling member 1840. In this case, the gaseous refrigerant remaining in the refrigerant supply unit 4000 (e.g., a cartridge or a refrigerant tank) leaks through the fluid passage, thereby minimizing user inconvenience that may be caused by the gaseous refrigerant being exposed to the atmospheric pressure.

At the same time, a user may apply a force to at least one gripping member 2310 or 2320 to remove at least one gripping member 2310 or 2320 from a groove formed in the threads of coupling member 1840.

The filter fixing module 2000 may include a sealing member 2400 that may prevent leakage of the refrigerant introduced into the filter fixing module 2000 through the perforated member 2200.

In this case, the filter fixing module 2000 may include a first sealing member 2410 and a second sealing member 2420, the first sealing member 2410 being received in a receiving surface extending in a first direction with respect to the body 2100, the perforated member 2200 passing through the second sealing member 2420, the perforated member 2200 extending in a second direction opposite to the first direction with respect to the body.

The first sealing member 2410 may perform a function of reducing leakage of the refrigerant flowing from the filter fixing module 2000 to the cooling device 1000.

The second sealing member 2420 may serve to reduce leakage of the refrigerant from the refrigerant supply unit 4000 to be supplied to the hollow holes of the perforated member 2200 of the filter fixing module 2000 to the outer surface of the perforated member 2200.

Meanwhile, the first sealing member 2410 may include a hollow hole through which the refrigerant may flow. For example, a hollow hole constituting a passage through which the refrigerant may flow may be formed in a central portion of the first sealing member 2410.

The second sealing member 2420 may include a through hole through which the perforated member 2200 may pass. For example, a through hole through which the body of the perforated member 2200 may pass may be formed in the central portion of the second sealing member 2420, and the shape and size of the through hole may correspond to those of the perforated member. For example, the inner diameter of the second sealing member 2420 defined by the through hole may be larger than the outer diameter of the perforated member 2200.

The filter fixing module 2000 according to the embodiment of the present application may be compatible with the refrigerant supply unit 4000 in the form of a cartridge and the refrigerant supply unit 4000 in the form of a refrigerant tank. For example, the perforated member 2200 of the filter fixing module 2000 may be provided to perforate a case or a hose connected to the refrigerant tank.

The structure and shape of the filter fixing module 2000 will be described in detail later with reference to fig. 9 to 18.

Hereinafter, referring to fig. 5, a process of cooling a target by the cooling system 10 according to an embodiment of the present specification will be described in detail.

Fig. 5 is a view showing a process of cooling a target by the cooling system 10 according to the embodiment of the present specification.

The control module 1700 may control whether to spray the refrigerant or the spray amount of the refrigerant introduced into the cooling device 1000 through the refrigerant moving hole formed inside the connection unit 1800.

For example, the control module 1700 may control the refrigerant flow control unit 1100 to control whether to inject refrigerant and/or the amount of refrigerant to be injected.

Further, the control module 1700 may control the refrigerant temperature control unit 1200 to control the temperature of the refrigerant flowing in the cooling device 1000. Thereby, the cooling device 1000 may spray the refrigerant having the controlled temperature characteristic to the target on the skin surface through the nozzle unit 1300 to supply cooling energy to the target so that the target may be cooled.

The process of performing the cooling function will be described in detail below.

The control module 1700 may control the temperature control members of the refrigerant temperature control unit 1200 to provide heat energy to the refrigerant flowing through the tubes of the refrigerant temperature control unit 1200 such that the temperature of the refrigerant reaches a preset temperature. For example, the control module 1700 may control the current (or voltage) value applied to the temperature control member of the refrigerant temperature control unit 1200 to increase/decrease or maintain the thermal energy applied to the refrigerant, so that the temperature of the refrigerant may be controlled. Further, the cooling system 10 according to the embodiment of the present application may control the temperature of the refrigerant to be injected, and eventually may control the temperature of the target to reach the preset temperature.

The sensor module 1400 may measure a temperature of the target that varies according to cooling energy transferred to the target by the refrigerant to obtain temperature information, and may transfer the obtained temperature information to the control module 1700.

Meanwhile, the temperature information obtained by the sensor module 1400 may include information about the temperature of a component (e.g., a temperature control member of the refrigerant temperature control unit 1200, etc.), or information about the ambient temperature of the cooling device 1000. Here, the sensor module 1400 may include a plurality of sensors to obtain various temperature information.

The control module 1700 generates a control signal based on the temperature information obtained by the sensor module 1400 to control the current applied to the temperature control member of the refrigerant temperature control unit 1200.

For example, the control module 1700 may use temperature information of the target obtained by the sensor module 1400 to use feedback control of control power applied to the temperature control means of the refrigerant temperature control unit 1200. Specifically, the control module 1700 may control the temperature of the target by using the following Proportional Integral Derivative (PID) control equation.

Here, P (t) represents an output value or a control value of a signal by which the control module 1700 controls the temperature control means, an error (t) represents a difference between a temperature of a target to be controlled by the control module 1700 and a temperature of the target measured by the sensor module 1400, and Cp, ci, and Cd may represent gain values or gains selected in the tuning process. Meanwhile, in the above control equation, each term is omitted, and P, PI and PD control may be used.

For another example, the control module 1700 may provide power corresponding to a specific temperature of a target to be controlled (or a temperature of the refrigerant) to the temperature control member in consideration of the type of refrigerant, a contact area between the temperature control member of the refrigerant temperature control unit 1200 and the refrigerant flow path, and the like.

The input module 1500 may obtain user inputs for presetting a cooling time and a target control temperature (or a control temperature of the refrigerant), etc. For example, the user may preset the injection time of the refrigerant to a preset time for which the refrigerant is injected to a target through the input module 1500. For another example, the user may preset the temperature of the target to be controlled through the input module 1500.

The input module 1500, which has obtained the user input, may transmit user input information related to the cooling time and/or the control temperature of the target to the control module 1700, and based on the input information, the control module 1700 may control the current (or voltage) value applied to the temperature control member of the refrigerant temperature control unit 1200, or whether to open/close the valve of the refrigerant flow control unit 1100, the opening/closing time of the valve, and the like.

Meanwhile, the input module 1500 may obtain input indicating start of cooling in addition to input information related to cooling conditions including a target cooling time and a control temperature, etc. For example, when the input of the input information related to the above cooling condition is completed, the user may perform an input indicating start of cooling through the input module 1500. In this case, the input module 1500 may be implemented to transmit an input signal indicating the start of cooling to the control module 1700, and the control module 1700 may be implemented to control the opening/closing of a valve of the refrigerant flow control unit 1100 or to control a current (or voltage) value applied to a temperature control member of the refrigerant temperature control unit 1200 in response to a user input indicating the start of cooling.

In this case, the input information related to the cooling condition and the input information indicating the start of cooling may be configured to be obtained through the input modules 1500 different from each other. For example, the input information related to the cooling condition is obtained through the first input module 1510, and the input information related to the cooling condition may be implemented as obtained through the second input module 1520, which is separate from the first input module 1510.

However, the above description is merely one example, and the input module is not limited thereto and may be configured such that input information related to a cooling condition and input information indicating start of cooling are obtained through a single input module.

The operation related to the input module will be described in detail later with reference to fig. 20 and 21.

The output module 1600 may output various information related to the cooling device 1000 and provide the information to a user.

For example, the output module 1600 may output real time temperature information of the target region via a display. Specifically, the sensor module 1400 may measure temperature information of the target and may transmit the measured temperature information of the target to the control module 1700. In this case, the control module 1700 may transmit the temperature information of the target to the output module 1600, and the output module 1600 may be configured to output the temperature information of the target region based on the obtained temperature information of the target.

The output module 1600 may output information related to the state of the cooling device 1000 and provide the information to a user.

For example, the control module 1700 may determine whether the first temperature sensor 1410 and the second temperature sensor 1420 are normal based on temperature information obtained from the first temperature sensor 1410 and the second temperature sensor 1420. In this case, the control module 1700 may provide the user with a result of determining whether the first temperature sensor 1410 and the second temperature sensor 1420 are normal through the output module 1600. For example, when it is determined that the first temperature sensor 1410 and the second temperature sensor 1420 are operating normally, a first alarm may be output through the output module 1600 in the form of a speaker, and when it is determined that at least one of the first temperature sensor 1410 and the second temperature sensor 1420 is not operating normally, a second alarm may be output through the output module 1600 in the form of a speaker.

However, the above is merely an example, and any suitable information related to the operation of the cooling device 1000 may be provided to a user in any form via the output module 1600.

The operation related to the output module 1600 will be described in detail later with reference to fig. 27 to 28.

The structure of the cooling device 1000 will be described below with reference to fig. 6 to 8.

Fig. 6 is a view showing an internal structural view of the cooling device 1000 according to the embodiment of the present specification. Referring to fig. 6, the cooling device 1000 may include a main body composed of a body portion and a grip portion, and the components of the cooling device 1000 described above may be provided in the body portion or the grip portion.

The main body of the cooling device 1000 may be divided into a body portion and a grip portion. For example, the body of the cooling device 1000 may include a body portion to which the filter fixing module 2000 and the refrigerant supply unit 4000 are mounted, and a grip portion that can be gripped by a user. Here, the body portion and the grip portion may constitute the cooling device 1000 such that the body portion and the grip portion are integrated with each other or coupled with each other by assembly although they are physically separated from each other.

The refrigerant flow control unit 1100, the refrigerant temperature control unit 1200, the nozzle unit 1300, the sensor module 1400, and the connection unit 1800 may be disposed inside the body part. Specifically, the refrigerant flow control unit 1100, the refrigerant temperature control unit 1200, the nozzle unit 1300, the sensor module 1400, and the connection unit 1800 may be disposed inside the body part with respect to the central axis CA of the body part. For example, the refrigerant temperature control unit 1200, the nozzle unit 1300, and the sensor module 1400 may be disposed near the front end F of the body portion, and the refrigerant flow control unit 1100 and the connection unit 1800 may be disposed near the rear end R of the body portion.

Meanwhile, the input module 1500 and the output module 1600 may be further disposed in the body portion. In this case, the input module 1500 may include a plurality of input devices, and each input device may be disposed near the front end F or the rear end R of the body portion. Further, the output module 1600 may include a plurality of output devices, and each output device may be disposed proximate to the front end F or the rear end R of the body portion.

Here, the central axis CA may refer to an axis formed in the longitudinal direction of the body portion through the center of the body portion, or may refer to an axis parallel thereto.

Here, the connection unit 1800 may constitute at least a part of the main body. For example, the connection unit 1800 may be formed at the rear end R of the body portion of the cooling device 1000. Alternatively, the connection unit 1800 may be implemented by being coupled to the body portion.

Here, the filter fixing module 2000 may be mounted to the main body. For example, at the rear end R of the body portion, the gripping members 2310 or 2320 of the filter fixation module 2000 can be mounted to the cooling device 1000 or removed from the cooling device 1000. For example, the gripping member 2310 or 2320 may be mounted to the cooling device 1000 or removed from the cooling device 1000 by a connection unit 1800 formed on the rear end R of the body portion. In particular, the gripping member 2310 or 2320 may be mounted to the cooling device 1000 or removed from the cooling device 1000 by at least one groove in the threads of the connection unit 1800 formed on the rear end of the body portion.

The control module 1700 may be disposed within the grip portion. For example, referring back to fig. 6, the control module 1700 may be disposed inside the grip portion along the longitudinal direction of the grip portion.

Further, the input module 1500 may be disposed inside or outside the grip portion.

For example, the input module 1500 (e.g., a button for indicating a cool start) may be provided at a location where a user's finger is located when the user grasps the grip portion. Accordingly, the user can press a button while grasping the cooling device 1000 to instruct start of cooling, thereby easily controlling the operation of the cooling device 1000.

For another example, the input module 1500 (e.g., a scroll switch or button, etc.) for presetting cooling conditions, such as a target cooling time and control temperature, may be disposed outside the grip portion (e.g., outside the end of the grip portion). Therefore, the user can easily preset the cooling condition before starting the cooling.

Further, the output module 1600 may be disposed inside or outside the grip portion.

For example, an output module 1600, such as a display indicating a status of a cooling operation (e.g., temperature information of a target, a remaining time of the cooling operation, etc.), may be provided on a portion of the grip portion (e.g., a rear surface of the grip portion) that is in a field of view of a user during use of the cooling device 1000. Accordingly, the user can easily obtain information about the cooling state (e.g., real-time target temperature, remaining cooling time, etc.), while performing a cooling operation by using the cooling device 1000.

Further, a switch for controlling whether to operate the cooling device, a power supply unit for supplying power to the cooling device 1000, any suitable heat dissipation member (such as a blower) for dissipating heat generated by the power supply unit, and a charging port may be provided in the grip portion.

Meanwhile, the arrangement of the components inside the body portion and the grip portion of the cooling device 1000 is not limited to the above description.

Fig. 7 is a view showing a refrigerant temperature control unit 1200 according to an embodiment of the present specification.

Referring to fig. 7, the refrigerant temperature control unit 1200 may include a temperature control member 1220, a porous member 1240, an insulating member 1260, and a tube.

The tube may be thermally coupled to the temperature control member 1220. For example, the tube may include a first surface in contact with a surface of the first temperature control member 1221 and a second surface in contact with a surface of the second temperature control member 1222. The tube may receive thermal energy from the first temperature control member 1221 and the second temperature control member 1222 through the first surface and the second surface. In this case, the tube shown in fig. 7 may be a tube integrated with the tube having the inlet 1110 shown in fig. 10. Alternatively, the tube shown in fig. 7 may be a tube separate from the tube having the inlet 1110 shown in fig. 10 to be connected to each other.

In this case, the tube and the temperature control member 1220 may be configured in a shape that allows efficient transfer of thermal energy or cooling energy. For example, at least a portion of the tube and the temperature control member 1220 may be implemented in a rectangular parallelepiped shape so as to be in surface contact with each other. Meanwhile, the shape of the tube and the temperature control member 1220 is not limited to the above-described rectangular parallelepiped shape, and may be implemented in various shapes that are in surface contact with each other.

Further, the first temperature control member 1221 and the second temperature control member 1222 may be fixed to the tube while being in contact with the tube surface.

Here, the temperature control member 1220 may include a first surface and a second surface that absorb or generate heat according to a direction of an applied current. In this case, preferably, the first surface of the temperature control member 1220 in contact with the surface of the pipe may be configured as a surface generating heat according to the direction of the applied current, and the second surface of the temperature control member 1220 may be configured as a surface absorbing heat such that the second surface is fixedly thermally coupled to the pipe. In this case, the temperature control member 1220 may transfer heat energy to the refrigerant flowing in the tube through the first surface.

Meanwhile, the porous member 1240 may be disposed inside the tube. The porous member 1240 disposed inside the tube may transfer thermal energy transferred from the temperature control member 1220 through the tube to the refrigerant. Here, the porous member 1240 may have a porous structure including a plurality of pores, and may have an increased contact surface with the refrigerant due to the porous structure, and thus may serve to more effectively transfer heat energy to the refrigerant passing through the plurality of pores.

An insulating member 1260 may be provided on the circumference of each of the first and second sides of the tube of the refrigerant temperature control unit 1200.

Referring again to fig. 7, a first insulating member 1261 may be disposed and secured between the nozzle unit 1300 and a first side of the tube on one side of the nozzle unit 1300. Thus, the first insulating member 1261 may thermally insulate the external components including the nozzle unit 1300 from the refrigerant temperature control unit 1200.

A second insulating member 1262 may be disposed and secured between the refrigerant flow control unit 1100 and a second side of the tube on one side of the refrigerant flow control unit 1100. Thus, the second insulating member 1262 may thermally insulate the external components including the refrigerant flow control unit 1100 from the refrigerant temperature control unit 1200.

Here, the insulating member 1260 may be made of a material having a thermal conductivity of 10W/(m×k) or less. For example, the insulating member 1260 may be made of polytetrafluoroethylene.

However, the positions, thermal conductivities, and materials of the above-described heat insulating members are merely examples, and the heat insulating members for insulating the external components from the refrigerant temperature control unit 1200 may be provided at any suitable positions, and may be made of any suitable materials having any suitable thermal conductivities.

Fig. 8 is a view showing a sensor module 1400 according to an embodiment of the present specification.

Referring to fig. 8, the sensor module 1400 may include a first temperature sensor 1410 and a second temperature sensor 1420.

The sensor module 1400 may be disposed in the body portion. For example, the sensor module 1400 may be provided outside the nozzle unit 1300 to be fixed thereto. In this case, the sensor module 1400 and the nozzle unit 1300 may be disposed inside the body portion such that a central portion of the measurement area of the sensor module 1400 corresponds to a central portion of the refrigerant injection area of the nozzle unit 1300. More specifically, the nozzle unit 1300 may include a guide unit 1310, and the guide unit 1310 may be in contact with the skin and may include a target defining member 1312 defining a target area. In this case, the sensor module 1400 may have a predetermined angle with respect to the central axis CA of the body portion, and may be fixed to the outer circumference of the nozzle unit 1300 such that the central portion C1 of the measurement region of the sensor module 1400 is substantially the same as the central portion C2 of the target region defined by the target defining member 1312.

The sensor module 1400 may include at least one temperature sensor. In other words, the sensor module 1400 may include a first temperature sensor 1410 and a second temperature sensor 1420.

In this case, the first temperature sensor 1410 and the second temperature sensor 1420 may be disposed in the same direction with respect to the nozzle unit 1300 in the body portion.

For example, referring again to fig. 8, the first temperature sensor 1410 and the second temperature sensor 1420 may be disposed at a lower end region of an inner surface of the body portion with respect to the nozzle unit 1300. For example, the front end portion of the first temperature sensor 1410 may be closer to the front end F of the body portion than the front end portion of the second temperature sensor 1420. That is, the first temperature sensor 1410 may be disposed closer to the front end of the body portion than the second temperature sensor 1420. With this structure, the size of the body portion can be minimized while precisely measuring the temperature of the target region.

At least one of the first temperature sensor 1410 and the second temperature sensor 1420 may measure temperature information of a target.

For example, temperature information of the target may be obtained based on the target temperatures measured by the first temperature sensor 1410 and the second temperature sensor 1420. For example, the temperature information of the target may be obtained by giving a weight to the target temperatures measured by the first and second temperature sensors, respectively, or by selecting one of the target temperatures measured by the first and second temperature sensors.

For another example, temperature information of the target may be obtained by using one of the first temperature sensor 1410 and the second temperature sensor 1420. Specifically, as described later in fig. 19, when it is determined that the first temperature sensor 1410 and the second temperature sensor 1420 are operating normally, only one of the first temperature sensor 1410 and the second temperature sensor 1420 may be activated to obtain temperature information of the target.

In particular, in the case where temperature information of the target is acquired using only the second temperature sensor 1420 provided by being spaced apart from the front end F of the body portion, a lens may be provided at the front end portion of the second temperature sensor 1420.

At least one of the first and second temperature sensors 1410 and 1420 may be used to save power required to operate the temperature sensor, thereby increasing the life of the sensor module 1400.

Meanwhile, as shown in fig. 8 (b), the first temperature sensor 1410 and the second temperature sensor 1420 may be disposed inside the body part to be symmetrical to each other with respect to the central axis CA of the body part. In this case, for the first and second temperature sensors 1410 and 1420, as shown in fig. 8 (a), the sensor module 1400 may be at a predetermined angle to the central axis CA of the body portion, and may be fixed on the outer circumference of the nozzle unit 1300 such that the central portion C1 of the temperature measurement regions of the first and second temperature sensors 1410 and 1420 is substantially the same as the central portion C2 of the target region defined by the target defining member 1312.

However, the arrangement of the sensor module 1400 described above is only one example, and the technical ideas of the present specification are not limited thereto, and the sensor module 1400 may be implemented in any suitable structure in which the temperature of the target area can be precisely measured and the size of the cooling device 1000 can be minimized.

Meanwhile, although not shown in the drawings, the cooling device 1000 according to the embodiment of the present specification may further include a refrigerant pressure maintaining member (refrigerant pressure holder) that maintains the pressure of the refrigerant at a preset pressure. For example, the refrigerant pressure maintaining member may be provided inside the cooling device 1000. For example, the refrigerant pressure maintaining member may be located in a grip portion that can be gripped by a user. For another example, the refrigerant pressure maintaining member may be located in the body portion.

The refrigerant pressure maintaining member allows the refrigerant to be maintained in a high pressure state, prevents a loss of refrigerant pressure, and allows the refrigerant to be injected at a rapid response speed.

For example, the refrigerant pressure maintaining member may cool the refrigerant. Specifically, the refrigerant pressure holding portion may cool the refrigerant by using a peltier element. Further, the refrigerant pressure maintaining member may cool the refrigerant before the refrigerant is introduced into the refrigerant temperature control unit 1200, so that the refrigerant introduced into the refrigerant temperature control unit 1200 may be maintained in a high pressure state. Further, a refrigerant pressure holding portion may be provided to further include a heat dissipating portion for dissipating heat generated by the peltier element.

In this case, the refrigerant pressure maintaining member may be applied to the cooling device 1000 using the refrigerant supply unit 4000 having a box shape related to fig. 2. However, the refrigerant pressure maintaining member may be more effectively applied to the cooling device 1000 using the refrigerant supply unit 4000 having the shape of a refrigerant tank in connection with fig. 3.

Hereinafter, the structure of the filter fixing module 2000 disclosed in the present specification and the coupling relationship of the filter fixing module 2000 and the cooling device 1000 will be described in detail with reference to fig. 9 to 18. The filter fixing module 2000 disclosed in the present specification may be provided in a structure capable of perforating the refrigerant supply unit 4000 and receiving a filter therein. Further, the cooling device 1000 disclosed in the present specification may include a coupling member 1840 having a structure in which the coupling member 1840 is coupled to the refrigerant supply unit 4000 such that the filter fixing module 2000 is received and disposed between the cooling device 1000 and the refrigerant supply unit 4000.

According to the embodiment disclosed in the present specification, the filter fixing module 2000 may be configured to have a structure in which the refrigerant supply unit 4000 screwed to the screw thread formed in the coupling member 1840 is perforated. Further, the filter fixing module 2000 may be configured to have a structure such that a filter may be received in the filter fixing module 2000. With such a structure, the filter fixing module 2000 according to the embodiment disclosed in the present specification may be provided to have a structure through which the refrigerant supply unit 4000 is coupled to the cooling device 1000, and the filter is received in the filter fixing module 2000 such that the refrigerant discharged from the refrigerant supply unit 4000 is introduced into the cooling device 1000 through the filter.

Meanwhile, the connection unit 1800 of the cooling device 1000 may be provided to have a threaded structure so as to be screwed to the refrigerant supply unit 4000. For example, a coupling member 1840 of the connection unit 1800, which will be described later, may include a screw structure, and thus may be provided to be screwed onto the screw of the refrigerant supply unit 4000. With this structure, it is possible to prevent the refrigerant discharged from the refrigerant supply unit 4000 from being exposed to the outside, thereby minimizing the risk due to expansion of the refrigerant.

Fig. 9 is a view showing an internal structure of a cooling device 1000 to which a filter fixing module 2000 is mounted according to an embodiment of the present specification.

Referring to fig. 9, the filter fixing module 2000 may be mounted to the connection unit 1800 of the cooling device 1000, and thus, a refrigerant may be supplied to the inlet 1110 of the refrigerant flow control unit 1100.

More specifically, the filter fixing module 2000 may be mounted to an inner surface of the coupling member 1840, and the coupling member 1840 is screwed to threads of an inner surface of the housing 1820 of the connection unit 1800. In this case, in a state in which the filter fixing module 2000 is mounted to the inner surface of the coupling member 1840, the front end portion FE of the coupling member 1840 may be connected to the end portion of the inlet 1110 of the refrigerant flow control unit 1100. For example, the front end FE of the coupling member 1840 and the inlet 1110 of the refrigerant flow control unit 1100 may be connected to each other by engagement of threads formed on the outer surface of the inlet 1110 of the refrigerant flow control unit 1100 with a third thread structure 1848 of the coupling member 1840, which will be described later.

The filter fixing module 2000 may be provided to have a structure in which a refrigerant flow path connected to the front end portion FE of the coupling member 1840 is provided. Accordingly, refrigerant may be introduced from the filter fixing module 2000 to the inlet 1110 of the refrigerant flow control unit 1100.

Fig. 10 is an exploded view of a cooling device 1000 mounted with a filter fixing module 2000 according to an embodiment of the present invention. Referring to fig. 10, a screw 1120 may be formed at an outer side of the inlet 1110 of the refrigerant flow control unit 1100.

Further, the coupling member 1840 of the connection unit 1800 may be provided as a structure including a base 1841, a first threaded structure 1842, and a second threaded structure 1844. Additionally, the first thread structure 1842 may include at least one groove 1846.

In this case, the first thread structure 1842 and/or the at least one groove 1846 may have the following structure: the filter fixing module 2000 may be received by or coupled to the structure.

For example, the gripping unit 2300 of the filter fixation module 2000 may be received in at least one groove 1846 formed in the first threaded structure 1842 such that the filter fixation module 2000 is detachably mounted to the coupling member 1840. This will be described in detail later with reference to fig. 12 to 18.

Second thread structure 1844 may be formed on the outside of first thread structure 1842. For example, the second thread structure 1844 may be formed on an outer surface of the coupling member 1840 in which the first thread structure 1842 is formed. Here, the second thread structure 1844 may be provided to be screwed to the housing 1820 of the connection unit 1800.

A thread 1822 may be formed on an inner surface of the housing 1820 with crests and roots corresponding with the second-thread formation 1844. In this case, the second thread structure 1844 is screwed onto the threads 1822 of the inner surface of the housing 1820, and thus the coupling member 1840 and the housing 1820 may be coupled to each other. For example, the housing 1820 may be screwed to the coupling member 1840 so as to surround the outside of the coupling member 1840, and with this structure, the cooling device 1000 or components of the filter fixing module 2000 (e.g., the coupling member 1840 and the inlet 1110 of the refrigerant flow control unit 1100) may be disposed so as to be surrounded by the housing 1820 so as to be protected from external impact.

Meanwhile, the housing 1820 may be provided to have a structure coupled with a coupling member formed outside the body portion of the cooling device 1000 main body. For example, a coupling member having a structure corresponding to a coupling member formed at the outer side of the body portion of the main body may be formed on the outer surface of the housing 1820, and the coupling member of the housing 1820 is sleeved on the coupling member formed at the outer side of the body portion of the main body, so that the housing 1820 may be fixedly coupled to the body portion of the main body.

Meanwhile, fig. 10 shows a housing 1820, which is a separate component from the main body of the cooling device 1000 and is connected to the main body of the cooling device 1000. However, this is merely one example, the housing 1820 may be configured as a unitary structure with the body of the cooling device 1000, and threads may be formed in an inner surface of the body such that the body is threaded onto the second thread structure 1844 of the coupling member 1840 described above.

Fig. 11 is a perspective view of a coupling member 1840 to which the filter fixing module 2000 is mounted according to an embodiment of the present invention.

Referring to fig. 11, coupling member 1840 may further include a third threaded structure 1848.

Third thread structure 1848 may be formed on an opposite side of first thread structure 1842 from base 1841 of coupling member 1840. In this case, the third thread structure 1848 may be provided to have crests and roots corresponding to the threads 1120 formed on the outside of the inlet 1110 of the refrigerant flow control unit 1100 described above. Thus, third thread structure 1848 may be threaded onto threads 1120 of inlet 1110. Thus, the coupling member 1840 and the refrigerant flow control unit 1100 may be connected to each other. In addition, the refrigerant moving channel of the filter fixing module 2000 may be connected to an end of the inlet 1110 of the refrigerant flow control unit 1100 through the refrigerant moving hole of the coupling member 1840. Thereby, the refrigerant discharged from the refrigerant supply unit 4000 may be introduced into the inlet 1110 of the refrigerant flow control unit 1100 through the refrigerant moving holes of the filter fixing module 2000 and the coupling member 1840.

However, the above-described structure is only an example, and any suitable coupling structure may be provided to supply the refrigerant from the filter fixing module 2000 to the inlet 1110 of the refrigerant flow control unit 1100 by using a suitable type of coupling member through which the filter fixing module 2000 is mounted to the cooling device 1000.

Referring to fig. 12, fig. 12 is a view illustrating that a filter fixing module 2000 is being coupled to a coupling member 1840 according to an embodiment of the present specification.

Referring to fig. 12, filter fixation module 2000 may be received in coupling member 1840 or coupled to coupling member 1840 such that gripping members 2310 and 2320 are received in at least two grooves 1846, respectively, grooves 1846 being formed in an inner surface of coupling member 1840. Meanwhile, although not shown in fig. 12, when the filter fixing module 2000 is received in the coupling member 1840, the refrigerant supply unit 4000 may be screwed onto the first screw structure 1842 of the coupling member 1840. Accordingly, the filter fixing module 2000 may be provided to be disposed between the cooling device 1000 and the refrigerant supply unit 4000, the refrigerant supply unit 4000 being screwed to the coupling member 1840 of the cooling device 1000.

Here, in order to facilitate the use of the filter fixing module 2000 by a user, the filter fixing module 2000 may include a grip unit 2300. For example, the grip unit 2300 may include at least two grip members 2310 and 2320. In other words, the grip unit 2300 may include a first grip member 2310 and a second grip member 2320. A user may apply a force to the first and second grip members 2310 and 2320 such that the filter fixing module 2000 may be easily installed to the cooling device 1000 or removed from the cooling device 1000.

Meanwhile, as described above, the coupling member 1840 may have a first thread structure 1842 including at least one groove 1846. In this case, the first and second gripping members 2310 and 2320 may be fitted into the at least one groove 1846 of the first threaded structure 1842. For example, first and second gripping members 2310 and 2320 may be provided in the shape of curved plates. In this case, a portion of the curved plate shape of each of the first and second gripping members 2310 and 2320 may be provided with a size and shape corresponding to the at least one groove 1846 of the first thread structure 1842. Thus, first gripping member 2310 fits into first groove 1846a of first threaded structure 1842, and second gripping member 2320 may fit into second groove 1846b of first threaded structure 1842, so that filter fixation module 2000 is removably mountable to coupling member 1840.

However, the structure and coupling relationship of the filter fixing module 2000 and the coupling member 1840 shown in fig. 12 are only one example, and should not be construed as being limited thereto. For example, multiple gripping members may be used in various forms such that the filter fixing module 2000 is removably mounted to the coupling member 1840. Alternatively, the filter fixing module 2000 may include any suitable type of coupling member other than the grip member, such that the filter fixing module 2000 may be mounted to the connection unit 1800 of the cooling device 1000.

Fig. 13 is a view showing an aspect of an embodiment according to the present invention, in which the refrigerant supply unit 4000 is screwed to the coupling member 1840 and perforated by the perforated member 2200 of the filter fixing module 2000.

Referring to fig. 13, as described above, in fig. 12, the first gripping member 2310 of the filter fixing module 2000 is received in the first groove 1846a of the first screw structure 1842 of the coupling member 1840, and the second gripping member 2320 of the filter fixing module 2000 is received in the second groove 1846b of the first screw structure 1842 of the coupling member 1840, so that the filter fixing module 2000 may be mounted to the coupling member 1840.

In this case, the refrigerant supply unit 4000 may have a structure capable of being perforated by the filter fixing module 2000 and coupled to the coupling member 1840.

For example, the refrigerant supply unit 4000 may include a refrigerant discharge hole perforated by the perforated member 2200 of the filter fixing module 2000. In this case, the diameter of the refrigerant discharge hole may be larger than the outer diameter of the body of the perforated member 2200. With this structure, the body of the perforated member 2200 can penetrate the refrigerant discharge hole of the refrigerant supply unit 4000.

Meanwhile, the outer surface of the body of the perforated member 2200 may be made of a material having high rigidity (e.g., steel or stainless steel). On the other hand, the refrigerant discharge hole of the refrigerant supply unit 4000 may be made of a material having low rigidity (e.g., aluminum alloy or copper alloy). For another example, the outer surface of the body of the perforated member 2200 may have a greater thickness than the refrigerant discharge hole of the refrigerant supply unit 4000. Thereby, the perforated member 2200 can be easily drilled in the refrigerant supply unit 4000.

Further, the refrigerant supply unit 4000 may have a structure that may be coupled to the first thread structure 1842 of the coupling member 1840. For example, the refrigerant supply unit 4000 may have a screw structure including crests and roots corresponding to the first screw structure 1842. Thus, the refrigerant supply unit 4000 may be coupled to the coupling member 1840 by being screwed onto the first threaded structure 1842 of the coupling member 1840.

The filter fixing module 2000 disclosed in the present specification may be provided as the following structure: this structure may receive the filter fixing module 2000 therein and perforate the refrigerant supply unit 4000, and thus the filter fixing module 2000 may be advantageously configured such that the refrigerant supply unit 4000 is more easily coupled to the coupling member 1840 and the refrigerant discharged from the refrigerant supply unit 4000 passes through the filter.

Referring to fig. 14 to 16, fig. 14 is an exploded view of a filter fixing module 2000 according to an embodiment of the present invention. Fig. 15 is a view showing the body 2100 and the grip unit 2300 of the filter fixing module 2000 according to an embodiment of the present specification. Fig. 16 is a view showing a relationship between the body 2100 of the filter fixing module 2000 and the first sealing member 2410 according to an embodiment of the present specification.

Referring to fig. 14 to 16, the filter fixing module 2000 according to the embodiment may include a body 2100, a perforated member 2200, a grip member 2310 or 2320, and at least one sealing member 2400.

Body 2100 may be configured to receive a filter and at least a portion of sealing member 2400.

For example, the body 2100 may be provided in the following structure: the structure includes a support surface 2120 for supporting the filter and sealing member 2400 and a receiving surface 2140 surrounding at least a side surface of the filter and sealing member 2400 and receiving at least a portion of the filter and sealing member.

The support surface 2120 may be provided to have a shape corresponding to that of the filter and sealing member 2400. For example, when each of the filter and the sealing member 2400 provided in the filter fixing module 2000 has a flat disc shape, the support surface 2120 may be provided to have a circular shape.

The receiving surface 2140 may be connected to a support surface 2120 of the body 2100. For example, the receiving surface 2140 may be provided to extend in a first direction from an outer edge of the support surface 2120.

In this case, the receiving surface 2140 may be provided to have a shape corresponding to the shape of the filter and the sealing member received in the receiving surface 2140.

For example, when each of the filters and the sealing members 2400 has a flat disc shape, the receiving surface 2140 may be disposed to surround at least a side surface of each of the filters and the sealing members 2400, and thus the receiving surface 2140 may be disposed to have a curved surface corresponding to that of each of the filters and the sealing members 2400.

For another example, the filter may be polygonal or star-shaped, and may have a size such that the vertex of the filter corresponds to the receiving surface 2140 to increase the contact surface between the receiving surface 2140 and the sealing member 2400, thereby improving the sealing property of the refrigerant.

Meanwhile, the body 2100 may further include a hole that may serve as a moving passage of the refrigerant. For example, referring to fig. 14 and 15, the body 2100 may be provided in the following structure: the structure includes a connection hole at a central portion of the support surface 2120 and connected to a second end of the perforated member 2200. The connection hole of the body 2100 may perform a function of a moving passage of the refrigerant, which receives the refrigerant discharged from the second end portion of the perforated member 2200, and discharges the refrigerant in a direction toward the cooling device 1000. For example, the refrigerant discharged from the connection hole of the body 2100 may be supplied to the inlet 1110 of the refrigerant flow control unit 1100 of the cooling device 1000 through the support surface 2120 of the body 2100 and the filter received by the receiving surface 2140. With this structure of the filter fixing module 2000, the refrigerant from which impurities are removed may be introduced into the cooling device 1000 and may be sprayed to the target, thereby minimizing contamination of the cooling device 1000 and the target due to impurities.

The perforating member 2200 may be connected to the support surface 2120 of the body 2100 and may serve to perform a function of perforating the refrigerant supply unit 4000. For example, the perforated member 2200 may include a first end adjacent to the support surface 2120 of the body 2100, a second end receiving the refrigerant discharged from the refrigerant supply unit 4000, and a body extending from the first end to the second end. For example, the perforated member 2200 may extend in a second direction opposite to the first direction in which the receiving surface 2140 extends relative to the support surface 2120 of the body 2100.

Meanwhile, the body of the perforated member 2200 may be provided in a structure including a hollow hole formed therein such that the refrigerant discharged from the refrigerant supply unit 4000 is outputted to the inlet 1110 of the refrigerant flow control unit 1100 through the coupling member 1840.

Gripping members 2310 and 2320 may extend from body 2100 and may be mounted to connection unit 1800.

For example, gripping members 2310 and 2320 may extend from support surface 2120 to the outside of support surface 2120, without receiving surface 2140 formed on support surface 2120. More specifically, gripping members 2310 and 2320 may be configured to extend from an outside of support surface 2120 in a second direction opposite the first direction, with no receiving surface 2140 formed on support surface 2120. The first and second gripping members 2310 and 2320 may be provided to have plate shapes substantially parallel to each other. In this case, as described above, the first and second grip members 2310 and 2320 may be provided to have a size and shape corresponding to those of the at least one groove 1846, such that the first and second grip members 2310 and 2320 may be received in the at least one groove 1846 included in the threads of the coupling member 1840 of the connection unit 1800 and mounted to the cooling device 1000.

As another example, each of the first and second gripping members 2310 and 2320 may be provided to have a curved flat plate shape. For example, referring back to fig. 15, each of the first and second grip members 2310 and 2320 may be provided to have a structure of a curved flat plate shape including a first region P1 extending in the second direction and a second region P2 extending in a direction at a predetermined angle to the second direction.

Specifically, the first grip member 2310 may be provided in a structure having a curved flat plate shape including a first region P1 extending in the second direction and a second region P2 extending in a third direction at a predetermined angle to the second direction. Meanwhile, the second grip member 2320 may be provided as a structure having a curved flat plate shape including a first region P1 extending in the second direction and a second region P2 extending in a fourth direction at a predetermined angle to the second direction. In this case, the fourth direction may be different from the third direction. In addition, the angle formed between the first area P1 of the first gripping member 2310 and the second area P2 of the first gripping member 2310 may be substantially the same as the angle formed between the first area P1 of the second gripping member 2320 and the second area P2 of the second gripping member 2320. Accordingly, the first and second gripping members 2310, 2320 may be provided with a substantially symmetrical structure to each other with respect to the central axis.

The first area P1 of the first gripping member 2310 and the first area P1 of the second gripping member 2320 are substantially parallel to each other and may be disposed a first distance apart from each other. Further, the second region P2 of the first gripping member 2310 and the second region P2 of the second gripping member 2320 may be disposed at a second distance from each other that is different from the first distance. In this case, the second distance may be shorter than the first distance, but according to an exemplary embodiment, the first and second grip members 2310 and 2320 may be disposed such that the second distance is longer than the first distance.

Meanwhile, as described above, at least a portion of the first area P1 of the first grip member 2310 may be received in at least one groove (1846 a) included in the thread of the coupling member 1840 of the connection unit 1800 and may be mounted to the cooling device 1000. Further, as described above, at least a portion of the second region P2 of the second gripping member 2320 may be received in at least one groove 1846b, the groove 1846b included in the threads of the coupling member 1840 to be mounted to the connection unit 1800 of the cooling device 1000.

With the structure of the first and second grip members 2310 and 2320 described above, the first and second grip members 2310 and 2320 may be configured to protrude outside the cooling device 1000. Accordingly, a user may easily apply a force to the first and second grip members 2310 and 2320 such that the filter fixing module 2000 may be easily removed from the cooling device 1000. This will be described in detail with reference to fig. 17 and 18.

Meanwhile, the filter fixing module 2000 may include at least one sealing member 2400. At least one sealing member 2400 may be used to prevent refrigerant leakage and block refrigerant from entering from the outside.

For example, the filter fixing module 2000 may include a support surface 2120 and a first sealing member 2410 received in the receiving surface 2140. Specifically, the first sealing member 2410 may be provided in the form of a flat disc, and may be disposed in a first direction with respect to the body 2100, and may be received in the filter fixing module 2000 through the receiving surface 2140. In addition, the first sealing member 2410 may be made of a material such as polytetrafluoroethylene.

The first sealing member 2410 may serve to prevent the refrigerant discharged through the first end of the perforated member 2200 from leaking to the outside. For example, the first sealing member 2410 may reduce leakage of the refrigerant by the contact surface of the support surface 2120 with the first sealing member 2410. In this case, in order to increase sealability by increasing the contact surface of the support surface 2120 with the first sealing member 2410, the filter may be configured to be smaller than the first sealing member 2410. For a specific example, the shape of the filter may be configured to have a polygonal shape or a star shape, with the vertex thereof corresponding to the outer circumference of the first sealing member 2410.

Meanwhile, the first sealing member 2410 may be provided in a structure including a hole 2412, the hole 2412 serving as a moving passage of the refrigerant discharged through the first end of the perforated member 2200. For example, the first sealing member 2410 may be provided to have a structure including a hole 2412 on a central portion thereof, and the hole 2412 of the first sealing member 2410 may be formed to have a structure in which the refrigerant discharged through the first end portion of the perforated member 2200 or through the filter may be received, and the received refrigerant may be discharged toward the cooling device 1000.

For another example, the filter fixing module 2000 may include a second sealing member 2420, the second sealing member 2420 being disposed at a side opposite to a side where the first sealing member 2410 is located with respect to the support surface 2120 of the main body 210. For example, the second sealing member 2420 fits into the body of the perforated member 2200 and may be disposed on a side (e.g., in the second direction) opposite to the side (e.g., in the first direction) on which the first sealing member 2410 is positioned relative to the support surface 2120 of the body 2100. Further, the second sealing member 2420 may be provided in a flat disc shape having a shape similar to the first sealing member 2410, and made of a material such as teflon.

The second sealing member 2420 may serve to reduce leakage of the refrigerant to be supplied to the hollow holes of the perforated member 2200 from the refrigerant supply unit 4000 to the outer surface of the perforated member 2200. In particular, the second sealing member 2420 may be provided to reduce leakage of the refrigerant discharged from the refrigerant supply unit 4000 and introduced into the second end portion of the perforated member 2200 through the outer surface of the perforated member 2200 to the outside.

Meanwhile, the second sealing member 2420 may be provided in a structure including a through hole 2422 through which the body of the penetration member 2200 is passed. For example, the second sealing member 2420 may be provided to have a structure including a through hole 2422 on a central portion thereof, and the through hole 2422 of the second sealing member 2420 may be provided to have a size and shape corresponding to the diameter and shape of the main body such that the body of the penetration member 2200 may be fitted into the through hole. For example, the inner diameter of the second sealing member defined by the through hole 2422 of the second sealing member 2420 may be larger than the outer diameter of the body of the piercing member.

Meanwhile, the second sealing member 2420 may be configured to be integrated with the refrigerant supply unit 4000. In this case, the second sealing member 2420 may be provided to be integrated with the refrigerant supply unit 4000 by an adhesive, or mechanically coupled to the refrigerant supply unit 4000 by having a shape corresponding to an end shape of the refrigerant supply unit 4000.

Due to the second sealing member 2420, when the refrigerant is introduced into the second end portion of the perforated member 2200 from the refrigerant supply device 4000, leakage of the refrigerant may be reduced.

Meanwhile, the filter may have a shape corresponding to the filter fixing module 2000, thereby appropriately fixing the filter in the filter fixing module 2000. For example, the filter may have a circular shape with a diameter corresponding to an inner diameter of the filter fixing module 2000 (e.g., an inner diameter of the receiving surface 2140).

Alternatively, in order to improve the sealing effect by increasing the contact area between the first sealing member 2410 and the support surface 2120, the filter may be polygonal in shape whose size is such that the vertex of the filter corresponds to the inside of the filter fixing module 2000, specifically, to the inner diameter of the receiving surface 2140. Alternatively, the filter may be provided to have a star shape such that the vertex of the filter corresponds to the inside of the filter fixing module 2000, in particular, to the inner diameter of the receiving surface 2140.

Further, the filter may be disposed in any path of the refrigerant flow path in the filter fixing module 2000.

For example, the filter may be located between the support surface 2120 of the body 2100 and the first sealing member 2410. In this case, the filter may perform a function of filtering out impurities contained in the refrigerant passing through the first end of the perforated member 2200 and the hole of the body 2100.

In this case, in order to increase the size of the contact surface between the first sealing member 2410 and the support surface 2120, the filter may have a polygonal shape or a star shape with its vertex intersecting the outer circumference of the first sealing member 2410.

However, the arrangement of the above-described filter is only one example, the filter is provided at an appropriate position in the refrigerant flow path in the filter fixing module 2000, and impurities in the refrigerant are removed, thereby supplying the impurity-removed refrigerant to the cooling device 1000. For example, a filter fixing module 2000 having any structure may be provided such that a filter may be located between the support surface 2120 of the body 2100 and the second sealing member 2420. Of course, the structure of the components of the filter fixing module 2000 may be variously changed in position according to the arrangement of the filters.

Further, although a filter is shown in fig. 14, the filter should not be considered to be included in the components of the filter fixing module 2000 disclosed in the present specification. Therefore, even if any filter manufactured or sold separately from the filter fixing module 2000 disclosed in the present specification is used, the filter should be construed as falling within the scope of claims of the filter fixing module 2000 disclosed in the present specification.

Referring again to fig. 14, the receiving surface 2140 of the body 2100 may be disposed to extend a first length L1 in the first direction from an edge of the support surface 2120. Meanwhile, the thickness of the first sealing member 2410 received in the receiving surface 2140 may be provided as the second length L2 along the first direction. In this case, the first length L1 and the second length L2 may be the same, but may be set to be different from each other.

For example, the receiving surface 2140 and the first sealing member 2410 may be provided such that the second length L2 is longer than the first length L1. With this structure, the first sealing member 2410 may be more easily provided to be received in the receiving surface 2140, or the received first sealing member 2410 may be removed from the receiving surface 2140. However, this is merely an example, and of course, the length of the receiving surface 2140 and the thickness of the first sealing member 2410 may vary.

Meanwhile, as described above, the perforated member 2200 may include a first end adjacent to the support surface 2120 of the body 2100, a second end receiving the refrigerant discharged from the refrigerant supply unit 4000, and a body extending from the first end to the second end. In this case, the length of the body in its longitudinal direction (e.g., second direction) may be provided as the third length L3. Further, the body of the perforated member 2200 may be disposed through the through hole 2422 of the second sealing member 2420. In this case, the thickness of the second sealing member 2420 may be set to the fourth length L4 along the second direction. In this case, the third length L3 and the fourth length L4 may be the same, but may be set to be different from each other.

For example, the perforated member 2200 and the second sealing member 2420 may be provided such that the third length L3 is longer than the fourth length L4. With this structure, the penetration member 2200 penetrates the through hole 2422 of the second sealing member 2420, and the remaining protruding portion of the body penetrates the refrigerant supply unit 4000, so that the refrigerant may be introduced from the refrigerant supply unit 4000 to the second end portion of the penetration member 2200, and the leakage of the refrigerant supplied from the refrigerant supply unit 4000 to the second end portion of the penetration member 2200 may be reduced by the second sealing member 2420. However, this is merely an example, and the length of the perforated member 2200 and the thickness of the second sealing member 2420 may be different.

Meanwhile, each of the first and second grip members 2310 and 2320 may be provided to have a fifth length L5 in the second direction. In this case, the third length L3 and the fifth length L5, which are body lengths of the perforated member 2200, may be the same, but may be different from each other.

For example, the perforating member 2200 and the first and second gripping members 2310 and 2320 may be provided such that the fifth length L5 is longer than the third length L3. As another example, the first and second gripping members 2310 and 2320 may be disposed such that the length of the first area P1 of each of the first and second gripping members 2310 and 2320 is greater than the third length L3.

With this structure, the first and second grip members 2310 and 2320 may protrude further outside than the refrigerant supply unit 4000 perforated by the perforation member 2200. Accordingly, when the use of the refrigerant supply unit 4000 is completed, the user may easily apply force to the first and second grip members 2310 and 2320, and may more easily remove the filter fixing module 2000 from the coupling member 1840.

Referring to fig. 16, the first sealing member 2410 may be sized and shaped to be received in the receiving surface 2140. For a particular example, the first sealing member 2410 may be provided to have a flat disk shape corresponding to the shape of the receiving surface 2140, and have a diameter for the first sealing member to be received in the receiving surface 2140.

For example, the diameter D1 of the first sealing member 2410 is less than the diameter D2 of the receiving surface 2140.

Thereby, the first sealing member 2410 may be received in the receiving surface 2140, and may effectively perform a function of reducing leakage of the refrigerant flowing from the first end portion of the perforated member 2200 to the cooling device 1000.

However, the shape and size of the first sealing member 2410 and the receiving surface 2140 shown in fig. 16 are merely examples, and the first sealing member 2410 and the receiving surface 2140 may be provided with any suitable shape and size to receive the first sealing member 2410 in the receiving surface 2140.

Referring to fig. 17, fig. 17 is a view showing a case in which the refrigerant supply unit 4000 is being removed from the coupling member 1840 and the filter fixing module 2000 according to an embodiment of the present invention.

Referring to fig. 17, as described above, the refrigerant supply unit 4000 may be perforated by the perforated member 2200 of the filter fixing module 2000 and screwed to the first screw structure 1842 of the coupling member 1840, thereby being mounted to the cooling device 1000. In this case, when the cooling device 1000 is being used, or after the use of the cooling device 1000 is completed, the user may disengage the refrigerant supply unit 4000 from the first screw structure 1842 of the coupling member 1840 by rotating the refrigerant supply unit 4000.

For example, when the refrigerant supply unit 4000 rotates counterclockwise (or clockwise), the threads of the refrigerant supply unit 4000 engage with the threads of the first thread structure 1842 of the coupling member 1840, such that the refrigerant supply unit 4000 moves in the second direction from the first direction. Thus, the threads of the refrigerant supply unit 4000 may be disengaged from the threads of the first thread structure 1842 of the coupling member 1840.

Further, when the refrigerant supply unit 4000 is rotated counterclockwise (or clockwise), the screw thread of the refrigerant supply unit 4000 and the screw thread of the first screw structure 1842 of the coupling member 1840 are engaged with each other, and thus the refrigerant supply unit 4000 is moved in the second direction from the first direction. Accordingly, the refrigerant supply unit 4000 may be spaced apart from the perforated member 2200. In other words, the refrigerant supply unit 4000 may be removed from the filter fixing module 2000.

Meanwhile, when the use of the refrigerant supply unit 4000 is completed, the gaseous refrigerant may remain in the refrigerant supply unit 4000. In this case, when the remaining refrigerant is suddenly exposed to the atmosphere, the refrigerant may suddenly expand due to a difference between the internal pressure of the refrigerant supply unit 4000 and the atmospheric pressure, which may generate noise and cause inconvenience to the user.

On the other hand, when the refrigerant supply unit 4000 disclosed in the present specification is removed from the coupling member 1840, particularly when the refrigerant supply unit 4000 starts to be removed from the perforated member 2200 of the filter fixing module 2000, a space that can be used as a fluid passage may be formed inside the coupling member 1840 between the refrigerant supply unit 4000 and the filter fixing module 2000. In this case, the gaseous refrigerant remaining in the refrigerant supply unit 4000 may use a region between the refrigerant supply unit 4000 and the filter fixing module 2000 as a fluid passage to be gradually discharged to the outside. Accordingly, the structure of the filter fixing module 2000 and the refrigerant supply unit 4000 disclosed in the present specification can minimize noise and inconvenience to a user caused by a pressure difference that may occur instantaneously when the refrigerant supply unit 4000 is removed from the cooling device 1000.

Fig. 17 shows only one aspect of removing the refrigerant supply unit 4000, but this is for convenience of explanation only. When the refrigerant supply unit 4000 is rotated clockwise (or counterclockwise), the threads of the refrigerant supply unit 4000 and the threads of the first thread structure 1842 of the coupling member 1840 are engaged with each other, and thus the refrigerant supply unit 4000 can be moved from the second direction to the first direction. Accordingly, the screw thread of the refrigerant supply unit 4000 may be screwed onto the first screw structure 1842 to be coupled to the coupling member 1840, and the refrigerant supply unit 4000 may be perforated by the perforation member 2200.

Referring to fig. 18, fig. 18 is a view illustrating an aspect of an embodiment according to the present invention in which the filter fixing module 2000 is being removed from the coupling member 1840.

Referring to fig. 18, as described above, the filter fixing module 2000 may be mounted to the connection member 1840 by: the first gripping member 2310 fits into a groove 1846a in the threads 1842 of the coupling member 1840 and the second gripping member 2320 fits into a groove 1846b in the threads 1842 of the coupling member 1840. In this case, when the cooling device 1000 is being used or the use of the cooling device 1000 is completed, the user may apply a force F1 to the first and second grip members 2310 and 2320 protruding to the outside, and may remove the filter fixing module 2000 from the coupling member 1840.

Specifically, a user may apply a force F1 to the second regions of the outwardly protruding first and second gripping members 2310 and 2320, and may remove the first and second gripping members 2310 and 2320 from the grooves 1846a and 1846b, respectively, contained in the threads 1842 of the coupling member 1840.

For example, a user may apply a pulling force F1 to the first and second gripping members 2310, 2320 and may remove the first and second gripping members 2310, 2320 from grooves 1846a and 1846b, respectively, contained in the threads 1842 of the coupling member 1840.

As another example, a user may apply a force to first and second gripping members 2310 and 2320 in a direction in which first and second gripping members 2310 and 2320 approach each other, and may remove first and second gripping members 2310 and 2320 from grooves 1846a and 1846b, respectively, contained in threads 1842 of coupling member 1840.

However, the directions of the forces applied to the first and second gripping members 2310 and 2320 shown in the present specification and drawings are merely examples, and forces may be applied to the first and second gripping members 2310 and 2320 in any suitable direction to remove the first and second gripping members 2310 and 2320 from the grooves 1846a and 1846b, respectively, contained in the threads 1842 of the coupling member 1840.

The filter fixing module 2000 according to the embodiment of the present specification may include a first grip member 2310 and a second grip member 2320 protruding to the outside so that a user can easily apply a force thereto. Therefore, when the use of the filter fixing module 2000 according to the embodiment of the present specification is completed, the filter fixing module 2000 can be easily removed from the coupling member 1840 with a small force.

The structure of the filter fixing module 2000 including the body 2100, the perforated member 2200, the grip unit 2300, and/or the sealing member 2400 is described above mainly with reference to fig. 9 to 18, thereby mounting the filter fixing module 2000 to the coupling member 1840.

However, the structure of each component including the filter fixing module 2000, the body 2100, the perforated member 2200, the grip unit 2300, and/or the sealing member 2400 described with reference to fig. 9 to 18 is only an example. Accordingly, the structure of each component of the filter fixing module 2000, the body 2100, the perforated member 2200, the grip unit 2300, and/or the sealing member 2400 should not be construed as being limited to the description of the present specification and the illustration of the drawings.

Meanwhile, although not shown in fig. 9 to 18, a cover for receiving the refrigerant supply unit 4000 may be provided at the outside of the refrigerant supply unit 4000. In this case, there may be threads or coupling elements on the outer surface of the cover of the refrigerant supply unit 4000. Further, threads or coupling elements corresponding to threads or coupling elements formed on the outer surface of the cover of the refrigerant supply unit 4000 may be formed on the outer surface of the housing 1820 of the connection unit 1800. Accordingly, the cover of the refrigerant supply unit 4000 may be coupled to the housing 1820 of the connection unit 1800 by screw connection, and thus, the refrigerant supply unit 4000 may be configured to be mounted to the cooling device 1000 while being received in the cover.

The cooling device 1000 according to the embodiment of the present specification may spray the refrigerant introduced according to the refrigerant flow control of the refrigerant flow control unit 1100 to the target area. Further, the cooling device 1000 may control the temperature of the refrigerant by the refrigerant temperature control unit 1200, and may spray the refrigerant to the target area. In this case, the cooling device 1000 may be implemented to measure the temperature of the target region in real time and control the temperature of the refrigerant based on the temperature of the target region. Further, the cooling apparatus 1000 may obtain a user input of a preset cooling condition through the input module 1500, or a user input indicating to start a cooling operation through the input module 1500. Further, the cooling device 1000 may provide cooling information to a user through the output module 1600 during cooling.

The above operations may be controlled by the control module 1700 of the cooling device 1000. For example, the control module 1700 may obtain an input related to a cooling condition or an input to initiate a cooling operation from the input module 1500, and may control the refrigerant flow control unit 1100 and/or the refrigerant temperature control unit 1200 of the cooling device 1000 to perform cooling corresponding to the input related to the cooling condition. In addition, the control module 1700 may control whether to activate the sensor module 1400 by determining whether the sensor module 1400 is operating properly.

Meanwhile, since the cooling device 1000 performs a cooling operation on a target area as a part of the body, safety of the cooling device 1000 is important. For this, the cooling device 1000 according to the embodiment of the present specification may include at least two temperature sensors. In this case, the cooling device 1000 may be used to determine whether at least two temperature sensors are operating properly. Thereby, the cooling device 1000 according to the embodiment of the present specification can measure the temperature of the target area, and can prevent an accident such as supercooling of the target area due to a failure of the temperature sensor.

Various operations of the control module 1700 controlling the components of the cooling device 1000 according to the embodiments of the present disclosure will be described below with reference to fig. 19 through 28.

Fig. 19 is a flowchart related to the operation of the control module 1700 according to an embodiment of the present disclosure for determining whether the sensor module 1400 is operating properly.

As shown in fig. 19, the method of determining whether the sensor module 1400 is operating properly may be initiated when the cooling device 1000 is activated by an input from a user opening a switch. Alternatively, the method of determining whether the sensor module is functioning properly may be initiated by additionally obtaining a user input that initiates an operation of determining whether the sensor module 1400 is functioning properly after the cooling device 1000 is activated. Alternatively, when the cooling device 1000 is activated, the control module 1700 may output information to the user indicating the initiation of an operation to determine whether the sensor module 1400 is functioning properly through the output module 1600. Here, through the input module 1500, the user may instruct the start of an operation of determining whether the sensor module 1400 is operating normally, and in response to an input of the user, the control module 1700 may be implemented to start an operation of determining whether the sensor module 1400 is operating normally.

Embodiments of a method of determining whether the sensor module 1400 is operating properly, which is performed by the control module 1700 disclosed in the present specification, will be described in detail below.

Referring to fig. 19, a method of determining whether a sensor module 1400 is operating properly may include: a step of activating the first temperature sensor and the second temperature sensor at S1100, a step of obtaining first temperature information measured by the first temperature sensor and second temperature information measured by the second temperature sensor at S1200, and a step of determining whether a difference between the first temperature information and the second temperature information is within a preset threshold at S1300. Further, the method of determining whether the sensor module 1400 is operating properly may include: a step of disabling at least one of the first temperature sensor and the second temperature sensor at S1400, or a step of disabling the first temperature sensor and the second temperature sensor at S1500 according to whether a difference between the first temperature information and the second temperature information is within a preset threshold.

In the step of activating the first and second temperature sensors at S1100, the control module 1700 may be implemented to activate the sensor module 1400 when the power of the cooling device 1000 is turned on and power to the control module 1700 is started.

For example, as described above, the sensor module 1400 may include at least two temperature sensors. In this case, the control module 1700 may control the sensor module 1400 such that the first temperature sensor 1410 and the second temperature sensor 1420 of the sensor module 1400 are activated.

When both the first temperature sensor 1410 and the second temperature sensor 1420 are activated, the sensor module 1400 may send a signal to the control module 1700 indicating that the first temperature sensor 1410 and the second temperature sensor 1420 are activated.

Referring to fig. 20, fig. 20 is a view illustrating an aspect of an embodiment according to the present specification, in which first temperature information and second temperature information are measured to determine whether the sensor module 1400 is operating normally.

For example, when the first and second temperature sensors 1410 and 1420 are activated, the control module 1700 may provide information to the user indicating that the guide unit 1310 is in contact with the temperature measurement region TD1 of the stand 3000 through the output module 1600.

When the user brings the guide unit 1310 into contact with the temperature measurement region TD1 of the stand 3000, each of the first and second temperature sensors 1410 and 1420 may measure the temperature of the temperature measurement region TD 1. In this case, the sensor module 1400 may implement such that first temperature information T1 obtained from the first temperature sensor 1410 and related to the temperature of the temperature measurement region TD1 of the stand 3000 and second temperature information T2 obtained from the second temperature sensor 1420 and related to the temperature of the temperature measurement region TD1 of the stand 3000 are transmitted to the control module 1700.

In step S1200 of obtaining first temperature information measured by the first temperature sensor and second temperature information measured by the second temperature sensor, the control module 1700 may obtain first temperature information T1 obtained from the first temperature sensor 1410 and second temperature information T2 obtained from the second temperature sensor 1420 through the sensor module 140.

In step S1300 of determining whether the difference between the first temperature information and the second temperature information is within the preset threshold, the control module 1700 may determine whether the first temperature sensor 1410 and the second temperature sensor 1420 are operating normally or the reliability of each of the first temperature information T1 and the second temperature information T2 based on the first temperature information T1 and the second temperature information T2 obtained from the sensor module 1400.

For example, when the difference between the first temperature information T1 and the second temperature information T2 is large, it is likely that the reliability of at least one of the first temperature information T1 and the second temperature information T2 is relatively low. On the other hand, when the difference between the first temperature information T1 and the second temperature information T2 is small, it is likely that the reliability of each of the first temperature information T1 and the second temperature information T2 is relatively high.

Accordingly, the control module 1700 may determine the reliability of each of the first temperature information T1 and the second temperature information T2 or whether the first temperature sensor 1410 and the second temperature sensor 1420 are operating normally based on the first temperature information T1 and the second temperature information T2.

For example, the control module 1700 may determine the reliability of each of the first temperature information T1 and the second temperature information T2 based on whether the difference between the first temperature information T1 and the second temperature information T2 is within a preset threshold.

Further, the control module 1700 may be configured to calculate a difference between the first temperature information and the second temperature information based on the first temperature information T1 and the second temperature information T2.

Further, the threshold value may be preset according to a difference between the first temperature information and the second temperature information.

In this case, the control module 1700 may determine whether the difference between the first temperature information and the second temperature information is within a preset threshold, and may thus control subsequent operations of the cooling device 1000.

For example, when the difference between the first temperature information and the second temperature information is not within the preset threshold, this may mean that the reliability of at least one of the first temperature information T1 and the second temperature information T2 is relatively low. Here, the relatively low reliability may mean that at least one of the first temperature sensor 1410 and the second temperature sensor 1420 is highly likely to malfunction. Alternatively, this may mean that the first temperature sensor 1410 and the second temperature sensor 1420 are operated normally, but any one of the measured first temperature information T1 and the measured second temperature information T2 is error due to an external factor.

Accordingly, when the difference between the first temperature information and the second temperature information is not within the preset threshold, the control module 1700 may control the cooling device 1000 such that a subsequent cooling operation of the cooling device 1000 is not performed. Accordingly, when the difference between the first temperature information and the second temperature information is not within the preset threshold, the control module 1700 may be configured to deactivate the first temperature sensor 1410 and the second temperature sensor 1420 and stop the cooling operation at S1500.

On the other hand, when the difference between the first temperature information and the second temperature information is within the preset threshold, this may mean that the reliability of each of the first temperature information T1 and the second temperature information T2 may be relatively high. Further, this may mean that at least one of the first temperature sensor 1410 that obtains the first temperature information T1 and the second temperature sensor 1420 that obtains the second temperature information T2 is highly likely to operate normally.

Accordingly, when the difference between the first temperature information and the second temperature information is within the preset threshold, the control module 1700 may be configured to perform a subsequent cooling operation of the cooling device 1000.

For example, in S1400, the control module 1700 may be configured to deactivate at least one of the first temperature sensor 1410 and the second temperature sensor 1420. As described above, when the difference between the first temperature information and the second temperature information is within the preset threshold value, this may mean that it is likely that "at least any one of the first temperature sensor 1410 that obtains the first temperature information T1 and the second temperature sensor 1420 that obtains the second temperature information T2 is operating normally, and thus at least any one of the first temperature sensor 1410 and the second temperature sensor T2 may be deactivated to save power required for temperature measurement of the temperature sensors.

Meanwhile, although not shown in fig. 20, the first temperature information and the second temperature information may be measured in response to an input of a user indicating temperature measurement through the input module 1500.

For example, in fig. 20, when the guide unit 1310 is in contact with the temperature measurement region TD1 of the stand 3000, the user may instruct the first temperature sensor 1410 and the second temperature sensor 1420 to perform temperature measurement through the input module 1500.

For example, a user may instruct the first temperature sensor 1410 and the second temperature sensor 1420 to take temperature measurements through a second input module 1520 located on the grip portion of the cooling device 1000. Here, the input indicating the temperature measurement may be related to an input indicating that temperature information of a specific area (e.g., the temperature measurement area TD1 of the stand 3000) for determining whether the first temperature sensor 1410 and the second temperature sensor 1420 are operating normally is obtained.

The control module 1700 may control the sensor module 1400 such that the first temperature sensor 1410 and the second temperature sensor 1420 measure temperature in response to user input.

Referring to fig. 21, fig. 21 is a graph showing a difference between first temperature information and second temperature information calculated by the control module 1700 to determine whether the sensor module 1400 is operating properly according to an embodiment of the present disclosure.

By the sensor module 1400, the control module 1700 may obtain first temperature information T1 from the first temperature sensor 1410 that is related to the temperature of the temperature measurement region TD1 of the rack 3000 and second temperature information T2 from the second temperature sensor 1420 that is related to the temperature of the temperature measurement region TD1 of the rack 3000.

For example, as described above, when the user turns on the switch, the first temperature sensor 1410 and the second temperature sensor 1420 may be activated. For example, a switch button may be formed at the lower end of the cooling device 1000 shown in fig. 20. In this case, when the user turns on the switch button, the first temperature sensor 1410 and the second temperature sensor 1420 may be activated. In this case, the first temperature sensor 1410 and the second temperature sensor 1420 may measure the temperature of the temperature measurement region from the point of activation. Accordingly, the control module 1700 may determine whether the first temperature sensor 1410 and the second temperature sensor 1420 are normal based on the measured temperature at any point in time from the point in time of activation.

As another example, as described above, the user may indicate the temperature of the measured temperature measurement zone TD1 through the input module 1500. In this case, after obtaining the user input, the control module 1700 may determine whether the first temperature sensor 1410 and the second temperature sensor 1420 are normal based on the measured temperature of the temperature measurement region TD 1. For example, the control module 1700 may be implemented to calculate the difference between the first temperature information T1 and the second temperature information T2 based on the first temperature information T1 and the second temperature information T2 at the point in time when the user input through the input module 1500 indicating temperature measurement is obtained.

Alternatively, the control module 1700 may be implemented to calculate the difference between the first temperature information T1 and the second temperature information T2 based on the first temperature information T1 and the second temperature information T2 at a point in time when a preset time elapses from a point in time when the user obtains an input indicating temperature measurement through the input module 1500.

However, the above description is merely exemplary, and of course, various control methods may be implemented, wherein the control module 1700 may determine whether the sensor module 1400 is operating properly based on temperature information obtained at any suitable time.

Further, referring to fig. 21, in the case of obtaining the user input, the first temperature information T1 and the second temperature information T2 are illustrated as being obtained even before the point in time of obtaining the user input, but this is merely an example, and of course, the first temperature information T1 and the second temperature information T2 may be implemented as being measured only when obtaining the user input.

Meanwhile, although not shown in fig. 19, when both the first temperature sensor and the second temperature sensor are activated in S1100, the control module 1700 may be configured to output information indicating that the first temperature sensor 1410 and the second temperature sensor 1420 are activated to the user through the output module 1600. For example, the control module 1700 may be configured to output information via the output module 1600 indicating that the first temperature sensor 1410 and the second temperature sensor 1420 are activated to indicate subsequent operations to a user.

For example, the control module 1700 may be configured to provide information to a user via the output module 1600 indicating that the guide unit 1310 is in contact with the temperature measurement region TD1 of the stand 3000.

For another example, the control module 1700 may provide information to a user through the output module 1600, the output module 1600 providing an alarm sound indicating that the first temperature sensor 1410 and the second temperature sensor 1420 are activated. For example, when the first temperature sensor 1410 and the second temperature sensor 1420 are activated, the control module 1700 may provide audible information to the user indicating that the first temperature sensor 1410 and the second temperature sensor 1420 are activated through the output module 1600.

In this case, as described above, the user may instruct the temperature measurement through the second input module 1520 to determine whether the first temperature sensor 1410 and the second temperature sensor 1420 are operating normally.

Meanwhile, although not shown in fig. 19, when it is determined at S1300 that the difference between the first temperature information and the second temperature information is within the preset threshold, the control module 1700 may output information indicating preset cooling time information and/or cooling temperature information to the user through the output module 1600.

For example, information related to the initiation of the presetting of the cooling time information and/or the cooling temperature information may be provided to the user in visual form through the output module 1600 having the shape of a display.

As another example, it is possible to provide information related to starting preset cooling time information and/or cooling temperature information to the user in an audible form through the output module 1600 having a speaker shape.

In this regard, the user may input cooling time information and/or cooling temperature information through the input module 1500. For example, the user may input cooling time information and/or cooling temperature information by using the first input module 1510 having the shape of the jog dial switch shown in fig. 24. This will be described in detail with reference to fig. 23 and 24.

However, the above description is merely exemplary, and of course, any suitable information may be provided to a user in visual form, audible form, tactile form, and/or the like.

Referring to fig. 22, fig. 22 is a view showing an aspect of an embodiment according to the present specification, in which at least any one of the first temperature sensor 1410 and the second temperature sensor 1420 is used to measure temperature information of a target.

For example, when measuring the temperature information of the target after step S1400, the control module 1700 deactivates the second temperature sensor 1420 and is located closer to the target, so that the temperature information of the target measured by the first temperature sensor 1410 can be obtained to more accurately measure the temperature of the center of the target.

For another example, when measuring temperature information of the target after step S1400, the control module 1700 may deactivate the first temperature sensor 1410 and may obtain temperature information of the target measured by the second temperature sensor 1420. In this case, the second temperature sensor 1420 is disposed farther from the target area than the first temperature sensor 1410, and thus the second temperature sensor 1420 may further include a lens 1430 for more precisely measuring temperature information of the target.

However, this is merely one example, and with respect to step S1400, the control module 1700 may be implemented to measure the temperature of the target area by using the first temperature sensor 1410 and the second temperature sensor 1420 to control the subsequent cooling operation.

Fig. 23 is a flowchart relating to an operation in which the control module 1700 obtains input for initiating a cooling operation according to an embodiment of the present disclosure. Fig. 24 is a view illustrating at least one input module 1500 according to an embodiment of the present specification. Fig. 25 is a view showing an aspect of an embodiment according to the present specification, in which information related to a cooling condition is obtained through the first input module 1510.

The cooling conditions associated with the cooling temperature and cooling time may vary depending on the type of treatment, the region of treatment, and the like. Accordingly, the cooling device 1000 according to the embodiment of the present specification may be implemented to preset cooling conditions related to a cooling temperature, a cooling time, and the like according to a treatment type of a user's target.

Referring to fig. 23, the method of acquiring input to start a cooling operation may include a step S2100 of acquiring cooling temperature information and cooling time information and a step S2200 of acquiring input to start a cooling operation by a user.

Referring to fig. 24, as described above, the cooling apparatus 1000 disclosed in the present specification may include at least one input module.

For example, the cooling apparatus 1000 includes an input module 1500, and a user can change an input form by inputting cooling time information and cooling temperature information or instructing to start a cooling operation using the input module 1500. For example, the cooling apparatus 1000 may be implemented such that different cooling time information and/or cooling temperature information is obtained by changing the time when a user presses one of the input modules 1500.

For another example, the cooling device 1000 may include a plurality of input modules 1500.

For example, the cooling device 1000 may include a first input module 1510 located near an end of the grip portion. The first input module 1510 may be provided in various forms as described above. For example, the first input module 1510 may be configured in the form of a scroll switch, and the control module 1700 may be configured to obtain different information based on a user's rotation or depression of the scroll switch of the first input module 1510.

For example, the cooling device 1000 may include a second input module 1520, the second input module 1520 being located at a portion where a finger is located when a user grasps the grip portion. The second input module 1520 may be provided in various forms as described above. For example, the second input module 1520 may be provided in the form of a button, and based on an input of a user pressing the second input module 1520, the control module 1700 may obtain an input indicating that a cooling operation is started or an input indicating that the temperature of the measured temperature measurement region TD1 is measured to determine whether the sensor module 1400 is operating normally as described above.

The cooling device 1000 may include a plurality of input modules 1500 and may provide a user with an intuitive form of input, thereby increasing user convenience.

Referring back to fig. 23, in step S2100 of acquiring cooling temperature information and cooling time information, the control module 1700 may acquire information related to cooling conditions, including cooling temperature information and cooling time information, through the first input module 1510.

Referring to fig. 25, the first input module 1510 may be provided in the form of a scroll wheel switch as described above.

Here, the user may input information related to the cooling condition by rotating or pushing the wheel switch.

For example, the user may rotate the first input module 1510 to obtain cooling temperature information. When the first input module 1510 is rotated in a first direction, a user may preset a high target temperature to control a target. On the other hand, when the first input module 1510 is rotated in the second direction, the user may preset a low target temperature to control the target. In this case, the output module 1600 may be configured to display a change in cooling temperature information to the user according to the rotation of the wheel switch. Meanwhile, the user may complete the preset of the cooling temperature information related to the target temperature by pressing the first input module 1510 to control the target.

For another example, the user may rotate the first input module 1510 to obtain cooling time information. The user may preset a long cooling time when rotating the first input module 1510 in a first direction. On the other hand, when the first input module 1510 is rotated in the second direction, the user may preset a short cooling time. In this case, the output module 1600 may be configured to display a change in cooling time information to the user according to the rotation of the wheel switch. Meanwhile, the user can complete the preset of the cooling temperature information related to the cooling time by pressing the first input module 1510.

However, the above description is only one example, and information related to the cooling condition may be obtained by various input devices using various methods other than the wheel switch. Further, the information related to the cooling condition may mean to contain any appropriate information related to the cooling operation in addition to the cooling temperature information and the cooling time information.

Referring back to fig. 23, in step S2200 of obtaining a user input to initiate a cooling operation, the control module 1700 may obtain a user input to initiate a cooling operation of the cooling device 1000.

For example, the control module 1700 may obtain user input from a user via a second input module 1520, different from the first input module 1510, indicating that a refrigeration operation is to be initiated. Specifically, the user may instruct the start of the cooling operation by pressing the second input module 1520 having a button shape. However, this is just one example, and the user input related to the start of the cooling operation may be obtained by various input devices using various methods other than the button.

As described above, when it is determined that the sensor module 1400 described with reference to fig. 19 is operating normally, the input of the cooling temperature information and the cooling time information may be initiated, and the user inputs the cooling temperature information and the cooling time information through the input module (e.g., the first input module 1510), and the cooling apparatus 1000 may cool the target area based on the preset cooling temperature information and the preset cooling time information.

However, this is only one example, and when the user does not input cooling temperature information and cooling time information through the first input module 1510 but inputs a start-up cooling operation through the second input module 1520, the cooling apparatus 1000 may be implemented to perform a cooling operation based on pre-stored cooling temperature information and cooling time information.

As described above, in response to a user input indicating that a cooling operation is to be initiated, the control module 1700 may control the refrigerant flow control unit 1100 and/or the refrigerant temperature control unit 1200 and may initiate the cooling operation. Further, the control module 1700 may be configured to control the current applied to the refrigerant temperature control unit 1200 based on information related to the cooling conditions, including the obtained cooling temperature information and cooling time information, and the temperature information of the target.

For example, the control module 1700 controls whether to turn on or off the refrigerant flow control unit 1100 and controls the thermal energy applied to the refrigerant by the refrigerant temperature control unit 1200 so that the degree of cooling delivered to the target area can be controlled.

For example, the control module 1700 controls whether to turn on or off the refrigerant flow control unit 1100 such that the degree of cooling is transferred to the target area.

For example, the control module 1700 controls whether to turn on or off the refrigerant flow control unit 1100 and the period of time for which the refrigerant flow control unit 1100 is turned on or off, and controls the thermal energy applied to the refrigerant by the refrigerant temperature control unit 1200, so that the degree of cooling transferred to the target area can be controlled.

A method of controlling the refrigerant flow control unit 1100 and/or the refrigerant temperature control unit 1200 by the control module 1700 will be described in more detail below with reference to fig. 26.

Fig. 26 is a flowchart illustrating a method of controlling the refrigerant flow control unit 1100 and/or the refrigerant temperature control unit 1200 by the control module 1700 according to an embodiment of the present invention.

Referring to fig. 26, the method of controlling the refrigerant flow control unit 1100 and/or the refrigerant temperature control unit 1200 by the control module 1700 may include a step S3100 of starting the refrigerant flow control unit 1100 and/or the refrigerant temperature control unit 1200, a step S3200 of obtaining a target measured temperature by the sensor module 1400, a step S3300 of controlling a current applied to the refrigerant temperature control unit 1200 based on preset cooling temperature information and the target measured temperature, and a step S3400 of determining whether a time of performing a cooling operation is within a preset cooling time.

At S3100, in response to a user input related to the cooling start-up of fig. 23, the control module 1700 may be configured to activate the refrigerant flow control unit 1100 and/or the refrigerant temperature control unit 1200.

For example, in response to a user input to initiate cooling, the control module 1700 may activate a valve of the refrigerant flow control unit 1100. Specifically, the control module 1700 may activate a valve to open a valve of the refrigerant flow control unit 1100. Further, the control module 1700 may be configured to control the opening/closing time of the valve of the refrigerant flow control unit 1100 based on the cooling time information preset with respect to fig. 23.

For example, in response to a user input to initiate cooling, the control module 1700 may activate the refrigerant temperature control unit 1200. For example, the control module 1700 may activate the first temperature control member 1221 and/or the second temperature control member 1222 of the refrigerant temperature control unit 1200. Further, based on the cooling time information and the cooling temperature information preset with respect to fig. 19, the control module 1700 may control the current value applied to the first temperature control member 1221 and/or the second temperature control member 1222 of the refrigerant temperature control unit 1200, thereby controlling the temperature of the initially injected refrigerant.

Meanwhile, although not shown in fig. 26, in S3100, the control module 1700 may activate the sensor module 1400 in addition to the refrigerant flow control unit 1100 and the refrigerant temperature control unit 1200. For example, as described in fig. 19 above, at least one of the first temperature sensor 1410 and the second temperature sensor 1420 may be configured to be activated even before step S3100. However, this is one example, even if the difference between the first temperature information T1 and the second temperature information T2 is within the preset threshold, the control module 1700 may be configured to deactivate the first temperature sensor 1410 and the second temperature sensor 1420 and then activate at least one of the first temperature sensor 1410 and the second temperature sensor 1420 at S3100.

In step S3200, in which the measured temperature of the target is obtained by the sensor module 1400, the control module 1700 may obtain the temperature of the target measured by the sensor module 1400. For example, the temperature of the target may be measured by at least any one of the first temperature sensor 1410 and the second temperature sensor 1420 of the sensor module 1400. In this case, the sensor module 1400 may transmit the measured temperature of the target to the control module 1700.

In step S3300 of controlling the current applied to the refrigerant temperature control unit 1200, the control module 1700 may control the current applied to the refrigerant temperature control unit 1200 based on the preset cooling temperature information obtained in fig. 23 and the target measured temperature obtained in S3200.

For example, when the preset cooling temperature is lower than the target measured temperature, the control module 1700 may decrease the current values applied to the first and second temperature control members 1221 and 1222 of the refrigerant temperature control unit 1200. Thereby, the heat energy applied to the refrigerant from the first and second temperature control members 1221 and 1222 may be reduced, and the temperature of the refrigerant may be controlled such that the target temperature approaches the preset cooling temperature.

For another example, when the preset cooling temperature is higher than the target measured temperature, the control module 1700 may increase the current values applied to the first and second temperature control members 1221 and 1222 of the refrigerant temperature control unit 1200. Thereby, the heat energy applied to the refrigerant from the first temperature control member 1221 and the second temperature control member 1222 may be increased, and the temperature of the refrigerant may be controlled so that the target temperature approaches the preset cooling temperature.

In step S3400 of determining whether the time at which the cooling operation is performed is within the preset cooling time, the control module 1700 may be configured to determine whether the time at which the cooling operation is performed is within the preset cooling time based on the preset cooling time information obtained with respect to fig. 23. To this end, the control module 1700 may be configured to additionally obtain time information and present time information at a point in time when the cooling operation begins (e.g., a point in time when the valve is open).

For example, when the time between the point in time when the cooling operation starts and the current point in time is shorter than the preset cooling time, the control module 1700 may determine that the time to perform the cooling operation is within the preset cooling time.

In this case, the valve of the refrigerant flow control unit 1100 may be controlled to be continuously actuated, thereby injecting the refrigerant to the target.

Further, when it is determined that the time to perform the cooling operation is within the preset cooling time, the control module 1700 may be configured to repeatedly perform step S3200 of obtaining the measured temperature of the target through the sensor module 1400, step S3300 of controlling the current applied to the refrigerant temperature control unit 1200 based on the preset cooling temperature information and the measured temperature of the target, and step S3400 of determining whether the time to perform the cooling operation is within the preset cooling time.

On the other hand, when the time between the point in time when the cooling operation starts and the current point in time exceeds the preset cooling time, the control module 1700 may be implemented to determine that the time to perform the cooling operation is not within the preset cooling time. In this case, the control module 1700 may be configured to stop the cooling operation.

For example, when it is determined that the time to perform the cooling operation is not within the preset cooling time, the control module 1700 may be configured to deactivate the valve of the refrigerant flow control unit 1100. Further, when it is determined that the time to perform the cooling operation is not within the preset cooling time, the control module 1700 may be implemented to deactivate the refrigerant temperature control unit 1200.

In other words, when it is determined that the time to perform the cooling operation is not within the preset cooling time, the control module 1700 may be configured to deactivate components of the cooling device 1000 (e.g., the refrigerant flow control unit 1100, the refrigerant temperature control unit 1200, the sensor module 1400, etc.) to stop the cooling operation.

Referring to fig. 27 and 28, fig. 27 is a flowchart showing a method in which the control module 1700 disclosed in the present specification outputs the measured temperature of the target through the output module 1600. Fig. 28 is a view showing an aspect of outputting a measured temperature of a target by the output module 1600 disclosed in the present specification.

Referring to fig. 27, the control module 1700 may obtain the measured temperature of the target from the sensor module 1400 in real time and may provide the measured temperature of the target to the user in real time through the output module 1600.

The method of outputting the measured temperature of the target through the control module 1700 may include step S3200 of obtaining the measured temperature of the target through the sensor module 1400, step S3210 of outputting the measured temperature of the target through the output module 1600, and step S3220 of determining whether the time for performing the cooling operation is within a preset cooling time.

In step S3200 of obtaining the measured temperature of the target by the sensor module 1400, as described above, the control module 1700 may obtain the temperature of the target measured by at least one of the first temperature sensor 1410 and the second temperature sensor 1420.

In step S3210 in which the measured temperature of the target is output through the output module 1600, the control module 1700 may transmit the measured temperature of the target obtained in step S3200 to the output module 1600.

Alternatively, the control module 1700 may transmit the cooling temperature information obtained according to FIG. 23 to the output module 1600.

Alternatively, the control module 1700 may transmit the remaining cooling time information calculated from the cooling time information and the cooling run time information obtained in FIG. 23 to the output module 1600. Here, as described above with respect to fig. 26, the cooling operation time information may be calculated based on the time information of the point in time at which the cooling operation starts and the current time information.

The output module 1600 may output real-time temperature information of the target based on the measured temperature of the target received by the output module. Alternatively, the output module 1600 may output target temperature information of the target based on the cooling temperature information received by the output module. Alternatively, the output module 1600 may be configured to output the remaining cooling time information to the user based on the remaining cooling time information received by the output module.

For example, referring to fig. 28, the output module 1600 may output real-time temperature information of the target and a target temperature of the target to the user. In this way, the user can compare the real-time temperature of the target with the target temperature of the target to be controlled, so that it can be intuitively checked whether the cooling operation is normally performed. Therefore, the cooling device 1000 according to the embodiment of the present specification can safely perform the skin cooling operation while preventing side effects caused by supercooling of the target.

For another example, referring to fig. 28, the output module 1600 may output the remaining cooling time information to a user. Thus, the user can immediately modify and supplement the cooling process plan by comparing the remaining cooling time to the targeted process schedule. Therefore, the cooling device 1000 according to the embodiment of the present specification can implement a cooling process in which side effects caused by supercooling of the target can be prevented and the effect of the process can be improved.

However, the illustration of FIG. 28 is merely an example for ease of description, and any suitable information may be treated and provided to a user via output module 1600.

Referring back to fig. 27, the control module 1700 may be configured to determine whether the time to perform the cooling operation is within the preset cooling time based on the preset cooling time information obtained with respect to fig. 23 in a similar manner to step S3400 of fig. 26.

In this case, the control module 1700 may be configured to repeatedly perform step S3200 of obtaining the measured temperature of the target through the sensor module 1400, step S3210 of outputting the measured temperature of the target through the output module 1600, and step S3220 of determining whether the time of performing the cooling operation is within the preset cooling time. That is, the control module 1700 may be configured to continuously obtain the measured temperature of the target and provide information about the measured target temperature to the user in real time through the output module 1600.

On the other hand, when the time between the point in time when the cooling operation starts and the current point in time exceeds the preset cooling time, the control module 1700 may determine that the time to perform the cooling operation is not within the preset cooling time. In this case, the control module 1700 may be configured to stop the cooling operation. For example, the control module 1700 may be configured to deactivate valves of the refrigerant flow control unit 1100 and the refrigerant temperature control unit 1200. In other words, the control module 1700 may be configured to deactivate components of the cooling device 1000 (e.g., the refrigerant flow control unit 1100, the refrigerant temperature control unit 1200, the sensor module 1400, etc.) in order to stop the cooling operation.

Various control operations of the control module 1700 are described above. However, this is merely one example, and any suitable method for controlling the target temperature to the target temperature may be implemented in order to minimize side effects of the cooling process and increase cooling efficiency while being safe.

As described above, the matters have been described in the best mode for carrying out the invention.
