The above-described objects, features and advantages of the present application will become more apparent through the following detailed description in conjunction with the accompanying drawings. However, since the present application can make various changes and have various embodiments, specific embodiments will be illustrated in the drawings and described in detail below.

In the drawings, the thicknesses of layers and regions are exaggerated for clarity, and elements or layers are referred to as “on” or “on” other elements or layers. This includes not only those directly on top of other components or layers, but also cases in which other layers or other components are interposed. The same reference numbers throughout the specification in principle refer to the same elements. In addition, components with the same function within the scope of the same idea shown in the drawings of each embodiment will be described using the same reference numerals, and overlapping descriptions thereof will be omitted.

If it is determined that a detailed description of a known function or configuration related to the present application may unnecessarily obscure the gist of the present application, the detailed description will be omitted. In addition, numbers (eg, first, second, etc.) used in the description of this specification are merely identifiers to distinguish one component from another component.

In addition, the suffixes “module” and “part” for components used in the following examples are given or used interchangeably only considering the ease of writing the specification, and do not have distinct meanings or roles in themselves.

In the following examples, singular terms include plural terms unless the context clearly dictates otherwise.

In the following embodiments, terms such as 'include' or 'have' mean the presence of features or components described in the specification, and exclude in advance the possibility of adding one or more other features or components. It's not like that.

In the drawings, the sizes of components may be exaggerated or reduced for convenience of explanation. For example, the size and thickness of each component shown in the drawings are arbitrarily shown for convenience of explanation, and the present invention is not necessarily limited to what is shown.

If an embodiment can be implemented differently, a specific operation sequence may be performed differently from the described sequence. For example, two operations described in succession may be performed substantially at the same time, or may be performed in an order opposite to the order in which they are described.

In the following embodiments, when membranes, regions, components, etc. are connected, not only are the membranes, regions, and components directly connected, but also other membranes, regions, and components are interposed between the membranes, regions, and components. This includes cases where it is indirectly connected.

For example, in this specification, when membranes, regions, components, etc. are said to be electrically connected, not only are the membranes, regions, components, etc. directly electrically connected, but also other membranes, regions, components, etc. are interposed between them. This also includes cases of indirect electrical connection.

In the following embodiments, the meaning that membranes, regions, components, etc. are fluidly connected may be interpreted to mean that each membrane, region, component, etc. forms at least a portion of a flow path through which fluid flows.

For example, in this specification, saying that configuration A is fluidly connected to configuration B may mean that fluid passing through the flow path formed by configuration A can reach the flow path formed by configuration B, or vice versa. . Specifically, when configuration A and configuration B are combined and the flow path formed by configuration A and the flow path formed by configuration B are directly connected, configuration A and configuration B can be considered to be fluidly connected. Alternatively, if configuration A and configuration B are connected through configuration C, such as a conduit, and the flow path formed by configuration A and the flow path formed by configuration B are indirectly connected through the flow path formed by configuration C, configuration A and configuration B It can be seen that they are fluidly connected. At this time, configuration C can be interpreted as fluidly connecting configuration A and configuration B. Additionally, it goes without saying that configuration A and configuration B can be fluidly connected through a plurality of configurations.

This specification relates to a cooling system operating in multi-mode. Specifically, the cooling system to be described in this specification may be a device that performs the function of lowering the temperature of an object or a system that performs that function as a collection of one or more separate modules. For example, the cooling system performs the function of lowering the temperature of an object for cosmetic or treatment purposes, and can operate in various modes depending on the type of procedure to be performed on the object.

In this specification, 'cooling' means lowering the temperature of an object by causing absorption of thermal energy of the object. Expressed differently, 'cooling' in this specification means lowering the temperature of the object by applying cooling energy to the object to absorb the heat energy of the object to be cooled. Here, cooling energy is used to express heat escaping by cooling, and applying cooling energy can be understood as a concept expressing a decrease in heat energy. For example, cooling may mean applying cooling energy to an object by 'spraying' coolant or air gas on the object to be cooled (i.e., non-contact method). For another example, cooling can be applied to an object by applying cooling energy to a cooling medium that can act as a heat object and 'contacting' the cooling medium to the object. In other words, cooling can be understood as a comprehensive concept that includes various methods of applying cooling energy to an object to be cooled.

Hereinafter, for convenience of explanation, a case in which the cooling system cools an object using a coolant will be described as a main embodiment, but the technical idea of the present specification is not limited to this. Here, cooling energy can be applied to objects such as carbon dioxide, liquid nitrogen, nitrogen dioxide (NO2), nitrogen monoxide (NO), nitrous oxide (N2O), HFC-based materials, methane, PFC, SF6, cooling water, and cooling gas as coolants. Materials available can be used.

In this specification, 'object' may mean a part or area to be cooled. For example, the target may refer to a body part on which skin beauty treatment is to be performed. For example, an object may refer to a part of the body, including a mole, wart, corn, or acne scar, that can be removed by cooling the localized area. As another example, the subject may include a part of the body that requires local anesthesia for hair removal, dermabrasion, botox treatment, or laser treatment.

Meanwhile, the cooling system may be used for skin care or treatment purposes such as alleviating inflammation (e.g., alleviating acne), alleviating itching, removing pigment lesions, vascular lesions, blemishes, removing fat, or whitening. Alternatively, the cooling system may be used to cool the object and directly destroy at least part of the object.

As an example, if the target is a part of the body including the above-mentioned skin moles, warts, corns, etc., the cooling system provides cooling energy to the target through the target surface, and the provided cooling energy causes tissue in the target to become necrotic or die. You can.

In another example, a cooling system provides cooling energy by spraying a coolant onto the target surface, and the provided cooling energy lowers the temperature of the nerves distributed beneath the target surface below the temperature at which the nerves are temporarily paralyzed or at which nerve transmission is blocked. This can cause the subject to become anesthetized or analgesic. The cooling system can cool the target surface and the interior of the target to an appropriate temperature range to produce this anesthetic or analgesic state for a certain period of time.

Hereinafter, for convenience of explanation, the subject is skin, and the case where coolant is sprayed on the skin surface to transfer cooling energy in the cooling system is described as a main embodiment, but the technical idea of the present specification is not limited to this and any body part. Of course, it can be a target.

In this specification, 'mode' can be understood as a concept that distinguishes the way the cooling system is driven. That is, when the cooling system has a first driving form and a second driving form, the cooling system can be understood as having two modes. At this time, the first driving form only means that at least one 'operation' is different from the second driving form, and does not mean that all 'operations' are the same.

In this specification, the cooling system may operate in 'multi-mode'. Specifically, the configurations of the cooling system may be controlled in different ways depending on which mode the cooling system is operating in.

As the cooling system operates in multi-mode, users can perform more diverse procedures using the cooling system. In other words, when the user wants to perform a first procedure that requires precise temperature control using a cooling system or a second procedure that requires spraying a cryogenic coolant, the user can set the temperature or cooling time to be controlled in the first procedure. While a cooling system may be used in a first driving form or operating in the first mode, in a second procedure, it may be operated in a second driving form or operating in a second mode to prevent unnecessary tissue necrosis or damage caused by the cryogenic coolant. A cooling system operating at can be used. At this time, the functions required or essential for each procedure may be different, so the cooling system needs to operate in multi-mode for different procedures.

[냉각 시스템][Cooling system]

Hereinafter, the cooling system 100 and its configuration will be described with reference to FIGS. 1 to 3.

Figure 1 is a diagram showing a cooling system 100 according to an embodiment of the present specification.

Referring to FIG. 1, the cooling system 100 may include a cooling device 1000 and a cartridge 2000.

The cooling device 1000 can cool the object by providing cooling energy to the object. Specifically, the cooling device 1000 may receive coolant from the outside and spray the supplied coolant back to the outside. In the process of spraying coolant from the cooling device 1000, the temperature of the coolant sprayed from the cooling device 1000 may be adjusted depending on the temperature of the target. The process by which the temperature of the coolant is controlled will be described later.

The cooling device 1000 may receive coolant from a coolant supply unit. Here, the coolant supply unit may be understood as a configuration that stores the coolant and is fluidly coupled to the cooling device 1000 to supply the coolant to the cooling device 1000. The coolant supply unit may be implemented in various forms such as a cartridge 2000 or a storage tank, as will be described later.

The cooling device 1000 may receive coolant from the cartridge 2000. Specifically, the coolant may be supplied while the cartridge 2000 is coupled to the cooling device 1000. Alternatively, the cooling device 1000 may receive coolant through a hose from a storage tank where the coolant is stored.

Furthermore, the cooling device 1000 may be implemented as a portable device connected to a cartridge 2000 so that the user can easily carry it, or may be implemented as a handpiece connected to a large device such as a coolant storage tank.

Hereinafter, for convenience of explanation, a case where the cooling device 1000 receives coolant from the cartridge 2000 will be described, but the technical idea of the present specification is not limited to this.

Cartridge 2000 may store coolant. The cartridge 2000 may be provided in a sealed state in which the coolant is stored at a constant pressure.

Cartridge 2000 may be coupled to cooling device 1000. As the cartridge 2000 is coupled to the cooling device 1000, a portion of the cartridge 2000 is perforated by the perforating member of the cooling device 1000, and thus coolant may flow into the cooling device 1000.

[냉각 시스템 구성][Cooling system configuration]

Figure 2 is a diagram showing the configuration of the cooling system 100 according to an embodiment of the present specification.

Referring to FIG. 2, the cooling system 100 includes a cooling device 1000 and a cartridge 2000, and the cooling device 1000 includes a nozzle 1100, a nozzle coupling portion 1200, and a temperature controller 1300. , it may include a flow rate control unit 1400, a coolant inlet unit 1500, a sensor unit 1600, an input unit 1700, an output unit 1800, a control unit 1900, and a distance maintaining unit (GD).

The nozzle 1100 can spray coolant. For example, the nozzle 1100 extends from one end to the other end to form a passage, but includes a portion where the width of the passage is relatively narrow, and the fluid passing through the nozzle expands as its pressure decreases as it passes through the narrow portion. As a result, it can be sprayed at high speed. The coolant expands adiabatically as it passes through the nozzle 1100 and has a very low temperature. As will be described later, the temperature of the coolant sprayed through the temperature control unit 1300 can be controlled to a desired temperature. The nozzle 1100 is detachable from the cooling device 1000, and details about this will be described later.

The nozzle 1100 may be of various types. For example, in the case of a procedure that destroys tissue within the target, such as the procedure to remove skin moles or warts described above, it is necessary to freeze the target at a relatively low temperature (e.g., about -50°C or lower). In this case, a relatively long nozzle 1100 may be used to narrow the distance between the target and the nozzle 1100 and provide low temperature coolant to the target. For another example, in the case of the above-mentioned cooling anesthesia or procedure for whitening effect, it is necessary to cool the object to a relatively high temperature (ex. about -30℃ to about 30℃), and in this case, the object and the nozzle A relatively short nozzle 1100 may be used so that a sufficient distance between the nozzles 1100 is secured and coolant at an appropriate temperature is provided to the target.

The nozzle coupling portion 1200 may be coupled to the nozzle 1100. The types of nozzles 1100 may vary as described above, and the types of nozzles 1100 coupled to the nozzle coupling unit 1200 may vary depending on the type of treatment to be performed on the subject.

The nozzle coupling portion 1200 may provide a flow path through which the coolant moves. For example, the nozzle coupling part 1200 includes an outlet hole, and the coolant supplied from the cartridge 2000 and introduced into the cooling device 1000 flows to the nozzle 1100 through the outlet hole of the nozzle coupling part 1200. can be provided.

The temperature control unit 1300 can control the temperature of the coolant. The temperature control unit 1300 can increase the temperature of the coolant by providing heat energy to the coolant or lower the temperature of the coolant by providing cooling energy, and can increase the temperature of the coolant according to the amount of heat energy provided by the temperature control unit 1300. can be adjusted.

The temperature control unit 1300 may include a temperature control member that produces heat energy.

As an example, the temperature control member may include an element (ex. thermoelectric element) that uses a thermoelectric effect such as Peltier's effect. For example, the temperature control member includes a thermoelectric element that absorbs heat on one side and generates heat on the other side depending on the direction in which the current is applied, so that the first side of the temperature control member produces heat energy, and the first side of the temperature control member produces heat energy. 2 sides can produce cooling energy. The temperature control member may produce heat energy depending on the power provided, and as the amount of power provided increases, the heat energy produced may increase.

The temperature control unit 1300 may further include a heat transfer member that transfers the heat energy produced by the temperature control member to the flow path through which the coolant moves. Additionally, the temperature control unit 1300 may further include a conduit defining a flow path through which the coolant moves.

The flow rate controller 1400 can control the movement of coolant. For example, the flow rate controller 1400 includes a valve, and the coolant may or may not move depending on whether the valve is opened or closed. Furthermore, the degree to which the coolant moves may be determined depending on the degree of opening or closing of the valve.

As an example, the flow rate controller 1400 may be controlled by the controller 1900. Specifically, the flow rate controller 1400 may perform an opening or closing operation according to an electronic signal obtained from the control unit 1900. At this time, the flow rate controller 1400 may include an electromagnetic valve (ex. solenoid valve).

As another example, the flow rate controller 1400 may be controlled according to the mechanical structure and movement of fluid. Specifically, the flow rate controller 1400 may perform an opening or closing operation depending on the pressure generated by the coolant moving along the flow path formed in the cooling device 1000. At this time, the flow rate controller 1400 may include a hydraulic valve (ex. pressure control valve).

As another example, the flow rate controller 1400 may be controlled according to user input. Specifically, the flow rate controller 1400 may be placed in an open or closed state by the user. At this time, the flow rate controller 1400 may include a manual valve (ex. globe valve).

The coolant inlet 1500 may accommodate at least a portion of the cartridge 2000. With the cartridge 2000 coupled to the coolant inlet 1500, the coolant stored in the cartridge 2000 may move to the main body MB.

In the process of spraying coolant using the cooling system 100, the coolant stored in the cartridge 2000 flows into the cooling device 1000 through the coolant inlet 1500, and the flow rate control unit 1400 and temperature control unit. It may be sprayed to the outside through (1300), the nozzle coupling portion (1200), and the nozzle (1100). Referring to FIG. 2, for this purpose, the coolant inlet 1500, the flow rate controller 1400, the temperature controller 1300, the nozzle coupling portion 1200, and the nozzle 1100 may be fluidly connected to each other. For example, the above-described components may be connected directly or indirectly through conduits or the like.

The sensor unit 1600 can measure the temperature of a specific area. For example, the sensor unit 1600 may include at least one temperature sensor for measuring the temperature of an object. At this time, the sensor unit 1600 may be built into the main body (MB) of the cooling device 1000 and arranged to face the direction in which the coolant is sprayed. In the process of performing a cooling procedure while the cooling device 1000 is in contact with an object, the sensor unit 1600 may measure the temperature of the area where the coolant is sprayed, the surrounding area, or the temperature of the coolant in the object. Here, the sensor unit 1600 may include a non-contact temperature sensor such as an infrared temperature sensor.

The sensor unit 1600 may further include at least one temperature sensor for measuring the temperature of a specific configuration within the cooling device 1000. For example, the sensor unit 1600 may include an overheating detection sensor to measure the temperature of the temperature control unit 1300. At this time, the overheating detection sensor may be a contact temperature sensor such as a thermocouple, resistance temperature sensor (RTD), or thermistor. Additionally, the overheating detection sensor may be thermally connected to at least a portion of the temperature controller 1300. For example, when the temperature control unit 1300 includes a temperature control member including a first side that produces heat energy and a second side that produces cooling energy, the overheating detection sensor is connected to the first side of the temperature control member. Alternatively, it may be in contact with or thermally connected to the second surface.

The sensor unit 1600 may provide a signal generated according to temperature measurement to the control unit 1900. The control unit 1900 may calculate the temperature of the target area based on the signal obtained from the sensor unit 1600 and control the temperature controller 1300 according to a control method described later. In addition, the control unit 1900 calculates the temperature of a specific component (ex. temperature control unit) within the cooling device 1000 based on the signal obtained from the sensor unit 1600, and if the calculated temperature is greater than a preset value, the Damage due to overheating can be prevented by stopping the operation of the component.

The input unit 1700 may receive a user's input. The input unit 1700 may include a trigger module 1720 and a manipulation module 1740.

The trigger module 1720 may be understood as a configuration for receiving a trigger input for spraying coolant from the cooling device 1000. Specifically, the trigger module 1720 provides a trigger signal to the control unit 1900 when receiving the user's input, and the control unit 1900 can open or close the flow rate control unit 1400 based on the received trigger signal. there is.

The trigger module 1720 includes at least one push button switch and can generate a trigger signal according to the user's pressing action. The input aspect of the trigger module 1720 is not limited to the above-described content, and the trigger module 1720 may be implemented as a microphone that uses technology such as voice recognition rather than a touch panel or mechanical operation.

The manipulation module 1740 may be understood as a configuration for determining variables that must be set before the cooling device 1000 sprays coolant. Specifically, when the manipulation module 1740 receives the user's input, it provides a manipulation signal to the control unit 1900, and the control unit 1900 can set the treatment temperature, operation time, etc., which will be described later, based on the obtained manipulation signal. .

The manipulation module 1740 includes at least one rotary switch and at least one push button switch, and is operated according to the user's rotation motion (e.g. clockwise or counterclockwise rotation motion) or pressure motion. A signal can be generated. The input aspect of the manipulation module 1740 is not limited to the above-described content, and the manipulation module 1740 may be implemented as a microphone that uses technology such as voice recognition rather than a touch panel or mechanical operation.

Here, the treatment temperature may refer to the temperature that the object to which the coolant is to be sprayed, for example, the skin surface, must reach. Additionally, the operation time may mean the time during which the spraying of the coolant must be maintained or the time during which the temperature of the skin surface must be maintained at the target cooling temperature while the temperature of the skin surface has reached the target cooling temperature.

The input unit 1700 may further include additional input means in addition to the trigger module 1720 and the manipulation module 1740 described above. For example, the input unit 1700 may further include a power button for turning on/off the power of the cooling device 1000.

The output unit 1800 may output to the user an interface for using the cooling device 1000, various information required for using the cooling device 1000, and a notification about the status of the cooling device 1000.

The output unit 1800 may include a notification output unit 1820 and a status output unit 1840.

The notification output unit 1820 can output a notification about the status or abnormality of the cooling device 1000. For example, the control unit 1900 may cause the notification output unit 1820 to output a notification about the currently operating control mode. For another example, the control unit 1900 may output a notification to the notification output unit 1820 about whether the cooling device 1000 is broken, whether the coolant is exhausted, whether the sensor unit 1600 is abnormal, etc. The notification output unit 1820 may include an LED element to visually output the above-described notification, or may include a speaker to audibly output the above-described notification.

The status output unit 1840 may output information about the current control mode, an interface for setting the aforementioned treatment temperature or operation time, or real-time information such as real-time temperature or coolant spray time. The status output unit 1840 may include an LCD panel to visually output the above-described information or interface, or it may include a speaker to audibly output the information or interface.

The control unit 1900 may control at least some of the components of the cooling device 1000. For example, the control unit 1900 may control at least the temperature control unit 1300, the flow rate control unit 1400, the sensor unit 1600, the input unit 1700, and the output unit 1800.

The controller 1900 may control the temperature controller 1300 to apply heat energy to the coolant. Additionally, the control unit 1900 may control the temperature control unit 1300 to adjust the amount of heat energy applied to the coolant.

The control unit 1900 may perform a temperature control method using at least the temperature control unit 1300 and the sensor unit 1600, as will be described later.

The control unit 1900 may use real-time temperature information calculated based on a signal obtained from the sensor unit 1600 when controlling the temperature control unit 1300. For example, the control unit 1900 determines the current temperature (here, the current temperature may mean a temperature corresponding to the temperature of the object, the temperature around the object, or the temperature of the coolant) based on the signal obtained from the sensor unit 1600. It is possible to control the amount of power applied to the temperature controller 1300 by calculating and comparing the calculated current temperature with the preset treatment temperature. Specifically, when the current temperature is higher than the preset treatment temperature, the controller 1900 can further lower the current temperature by reducing the amount of power provided to the temperature controller 1300 to reduce the heat energy applied to the coolant. Alternatively, if the current temperature is lower than the preset treatment temperature, the controller 1900 may further increase the current temperature by increasing the amount of power provided to the temperature controller 1300 to increase the heat energy applied to the coolant. The control unit 1900 may use a Proportional-Integral-Derivative (PID) control method to adjust the amount of power provided to the temperature control unit 1300.

The control unit 1900 may further use the flow rate control unit 1400 when performing the temperature control method. For example, the controller 1900 may decrease the opening degree of the flow rate controller 1400 to increase the current temperature, and may increase the opening degree of the flow rate controller 1400 to lower the current temperature.

According to the temperature control method described above, the cooling system 100 of the present specification is capable of precise cooling control by controlling the temperature of the object in real time to maintain it at a specific temperature (ex. preset treatment temperature).

Meanwhile, the control unit 1900 may block power supplied to at least some of the components of the cooling device 1000 based on the signal obtained from the sensor unit 1600. For example, the control unit 1900 calculates the temperature of the temperature control member of the temperature control unit 1300 using the above-described overheating detection sensor, and when the calculated temperature exceeds the preset damage threshold temperature, the temperature control unit ( 1300) may be blocked.

The controller 1900 may control the flow rate controller 1400 to move the coolant or prevent the movement of the coolant.

The control unit 1900 may use a signal obtained from the input unit 1700 when controlling the flow rate control unit 1400. For example, the control unit 1900 may control the flow rate controller 1400 using a trigger signal obtained from the input unit 1700.

The control unit 1900 may include a central processing unit (CPU), a microprocessor, a processor core, a multiprocessor, or an application-specific integrated integrated circuit (ASIC), depending on hardware, software, or a combination thereof. It can be implemented with devices such as circuit) and FPGA (field programmable gate array). The control unit 1900 may be provided in the form of an electronic circuit that performs a control function by processing electrical signals in hardware, or may be provided in the form of a program or code that drives the hardware circuit in software.

Meanwhile, the cooling device 1000, although not shown in FIG. 4, further includes a memory that stores control programs loaded or executed by the control unit 1900, a power supply unit that supplies power necessary for operation of the cooling device 1000, etc. can do.

[냉각 시스템 구조][Cooling system structure]

FIG. 3 is a cross-sectional view of the cooling system 100 according to an embodiment of the present specification.

Referring to FIG. 3, in the cooling system 100, the main body (MB) of the cooling device 1000 includes a nozzle coupling part 1200, a temperature control part 1300, a flow rate control part 1400, a sensor part 1400, The input unit 1700, output unit 1800, and control unit 1900 may be built-in or mounted. Additionally, the nozzle 1100, the distance maintaining part (GD), and the coolant inlet 1500 may be coupled to the main body (MB) of the cooling device 1000. Furthermore, the cartridge 2000 may be coupled to the cooling device 1000.

Some components of the cooling device 1000 may be arranged along the imaginary line VL. For example, referring to FIG. 3, the nozzle 1100, the nozzle coupling part 1200, the temperature control part 1300, the flow rate control part 1400, and the coolant inlet 1500 form an imaginary line (VL). It can be arranged accordingly.

As the above-described components are arranged along the virtual line (VL), a coolant flow path can be formed along the virtual line (VL), and the coolant can move through the formed coolant flow path.

Here, the temperature control unit 1300 may be located between the nozzle 1100 and the coolant inlet 1500. Specifically, the temperature control unit 1300 may be located between the nozzle coupling unit 1200 and the flow rate control unit 1400. Alternatively, the temperature control unit 1300 may be located between the flow rate control unit 1400 and the coolant inlet 1500. The temperature control unit 1300 is disposed between the nozzle 1100 and the coolant inlet 1500, so that the coolant introduced through the coolant inlet 1500 is applied to the temperature control unit 1300 before being sprayed through the nozzle 1100. The temperature can be adjusted by

The cooling system 100 shown in FIG. 4 is a schematic diagram of the cooling system 100 according to an embodiment that can be implemented using the configuration shown in FIG. 3, and the structure of the cooling system 100 in this specification is It is not limited to the above. As an example, the cooling system 100 may be implemented in which the temperature control unit 1300 is disposed between the flow rate control unit 1400 and the cartridge 2000.

[냉각 시스템 조립 형태][Cooling system assembly form]

Some components of cooling system 100 may be separate and combined with each other.

FIG. 4 is a diagram showing how some components are assembled in the cooling system 100 according to an embodiment of the present specification.

Referring to FIG. 4, the cooling device 1000 and the cartridge 2000 can be separated from the cooling system 100, and the cooling device 1000 includes a main body (MB), a nozzle 1100, and a distance maintaining unit (GD). can be separated into

Various coupling methods may be used to combine components separated from the cooling system 100 with each other. Below, the main method of combining each component is described, but it should be noted in advance that the technical idea of the present specification is not limited to this.

The main body (MB) may be coupled to the cartridge 2000 through screw coupling. For example, it includes a coolant inlet 1500 of the main body MB, and at least a portion of the coolant inlet 1500 and at least a portion of the cartridge 2000 correspond to a coupling portion (e.g., a portion provided with a screw thread). ), the cartridge 2000 may be coupled to the cooling device 1000 through the coolant inlet 1500. In addition to the above-described coupling method, the main body (MB) and the cartridge 2000 may be coupled by other methods such as a magnetic coupling method, a sliding coupling method, or an interference fitting method.

The main body MB may be coupled to the nozzle 1100 through screw coupling. The nozzle 1100 may be coupled to the nozzle coupling portion 1200 of the main body MB through screw coupling. At this time, the nozzle coupling portion 1200 and the nozzle 1100 of the main body MB may each include corresponding coupling portions (ex. portions with threads). For example, the nozzle 1100 includes a first coupling portion having a thread formed on an inner diameter surface, and the nozzle coupling portion 1200 includes a second coupling portion having a thread formed on an outer diameter surface. The first coupling portion and the second coupling portion of the nozzle coupling portion 1200 may be screwed together. In addition to the above-described coupling method, the main body (MB) and the nozzle 1100 may be coupled by other methods such as a magnetic coupling method, a sliding coupling method, or an interference fitting method.

The main body (MB) can be coupled to the distance maintaining part (GD) through magnetic coupling. Specifically, the main body MB includes a magnetic member at least in part, and the distance maintaining part GD also includes a magnetic member corresponding to the magnetic member of the main body MB in at least a part, so that the distance maintaining part GD has a magnet. It can be easily coupled to the main body (MB) or easily separated from the main body (MB) through coupling. In addition to the above-described coupling method, the main body (MB) and the distance maintaining part (GD) may be coupled by other methods such as interference fitting, sliding coupling, or screw coupling.

Cooling system 100 may be assembled as follows. First, the nozzle 1100 is coupled to the main body MB, the distance maintaining unit GD is coupled, and then the cartridge 2000 can be coupled. Alternatively, after the cartridge 2000 is coupled to the main body MB, the nozzle 1100 may be coupled, and the distance maintaining unit GD may be coupled.

By disassembling or assembling some components of the cooling system 100 as described above, the cooling system 100 may become easier to operate in multi-mode. For example, when the type of nozzle 1100 and/or the distance maintaining unit (GD) varies depending on the type of procedure, the user can change the nozzle 1100 and/or the distance maintaining unit (GD) to one Different types of procedures can be performed with the cooling device 1000.

[동작 모드 결정][Determination of operation mode]

As described above, the cooling system 100 according to an embodiment of the present specification monitors the temperature of the object, the temperature around the object, or the coolant temperature (hereinafter 'current temperature') in real time to set the temperature of the object to a specific temperature. A precise temperature control method is used to maintain the temperature.

As the cooling system 100 uses the precise temperature control method described above, different types of procedures can be performed in one device or system. Specifically, treatments with different treatment temperature ranges (e.g., freezing tissue to about -70°C to -50°C for removal of abnormal tissue and about -30°C to 30°C for skin beautification) procedures such as cooling tissue to degrees Celsius) can be performed in one device or system.

At this time, when performing different types of procedures, the cooling system 100 needs to be equipped with a control method suitable for each procedure.

For example, in the case of procedures where the operating temperature is relatively low, such as freezing procedures for tissue decomposition or destruction, safety needs to be ensured during the procedure, and a special safety control method may be required to ensure safety. On the other hand, in the case of procedures where the treatment temperature is relatively high, such as for the purpose of skin care or pain relief in laser treatment, a separate safety control method to ensure safety may not be necessary.

As another example, in the case of a procedure for the purpose of skin care or to relieve pain from laser treatment, it is necessary to set the treatment temperature or operation time differently depending on the situation. For this reason, before operating the cooling system 100, the treatment temperature or operation time needs to be set differently. There is a need to provide an interface for setting variables such as operation time, and furthermore, there is a need to provide notifications to users based on the set variables. On the other hand, in the case of freezing procedures for tissue decomposition or destruction, setting the treatment temperature is not necessary because the temperature of the coolant is sufficient as long as it is below the critical value, and for safety reasons, it is necessary to operate only when there is a user's operation, so setting the operation time is also unnecessary. can do.

As described above, the cooling system 100 needs to operate in multiple control modes to operate in the most appropriate manner depending on the type of procedure.

Hereinafter, how the cooling system 100 operates will be described with reference to FIGS. 5 to 11.

Figure 5 is a diagram showing the operation process of the cooling system 100 according to an embodiment of the present specification.

Referring to FIG. 5, the cooling system 100 includes a step in which the cooling device 1000 is turned on (S110), a step in which the operation mode is determined (S130), and the cooling device 1000 is driven according to the operation mode. It may include step S150.

Each step is described in detail below.

In the cooling system 100, the cooling device 1000 may be turned on by the user (S110). The cooling device 1000 includes a switch for turning on/off the power, and can be turned on or off according to the user's input.

The operation mode of the cooling device 1000 may be determined (S130). The operation mode may be determined according to preset conditions. Separate configuration or user input may be used in determining the operation mode.

For example, the operation mode may be determined depending on the type of nozzle 1100 coupled to the cooling device 1000. Specifically, the cooling device 1000 further includes a recognition switch that operates depending on the type of the nozzle 1100 to which it is coupled, and the control unit 1900 operates the cooling device 1000 in a specific operation mode depending on whether the recognition switch operates. It can be controlled to operate.

As another example, after the cooling device 1000 is turned on, the operation mode may be determined according to input received from the user.

As another example, the cooling device 1000 includes a separate selection switch, and the operation mode may be determined depending on the operation of the selection switch.

Meanwhile, the operation mode may already be determined. For example, the cooling device 1000 may operate in a default operating mode when turned on. In other words, the step (S130) in which the operation mode is determined is a step that includes not only the case where the operation mode of the cooling device 1000 is determined by certain conditions, but also the case where the cooling device 1000 operates in a specific mode from the beginning. It can be understood.

The determined operating mode can be changed. For example, the cooling device 1000 may change the operation mode by receiving a user's input. For another example, if the operation mode is determined depending on the type of nozzle 1100 coupled to the cooling device 1000, the operation mode may change if the type of nozzle 1100 coupled to the cooling device 1000 changes. You can.

The operation mode may include at least one mode. For example, the operating mode may include at least a cooling mode, a freezing mode, and a boosting mode. The cooling mode may correspond to a control method when the treatment temperature is a relatively high temperature, and the freezing mode may correspond to a control method when the treatment temperature is a relatively low temperature. Additionally, the boosting mode may correspond to a control method when spraying the composition together with the coolant. In other words, the cooling mode is a control method that is preferably used in procedures aimed at the aforementioned skin care or cooling anesthesia, and the freezing mode is preferably used in procedures aimed at tissue decomposition or tissue destruction, etc. It is a control method, and boosting mode is a control method used when spraying a composition in skin care or medical procedures.

The cooling device 1000 may be driven according to the operation mode (S150). The control unit 1900 may control the configurations of the cooling device 1000 as described later based on the determined operation mode.

[쿨링 모드][Cooling Mode]

Hereinafter, a method of operating the cooling device 1000 in a cooling mode according to an embodiment of the present specification will be described with reference to FIGS. 6 to 8.

FIG. 6 is a diagram illustrating a method of controlling the cooling system 100 in a cooling mode according to an embodiment of the present specification.

7 and 8 are diagrams showing the status output unit 1840 of the cooling system 100 in a cooling mode according to an embodiment of the present specification.

Referring to FIG. 6, the control method of the cooling system 100 in the cooling mode includes checking whether the sensor is malfunctioning (S210), setting the treatment temperature and operation time (S220), and outputting status information (S210). S230), determining whether the first operation condition is satisfied (S240), spraying coolant (S250), controlling the temperature of the object (S260), determining whether the first stopping condition is satisfied (S240) S270), and a step of stopping coolant injection (S280).

Each step is described in detail below.

The control unit 1900 can check whether the sensor is malfunctioning (S210). In the cooling mode, the cooling device 1000 aims to cool the current temperature to the treatment temperature and maintain the current temperature at the treatment temperature during the operating time, as described later, so it is necessary to monitor the current temperature in real time. . Therefore, since a malfunction of a sensor for temperature monitoring is fatal to the operation of the cooling device 1000, it is very important to check whether the sensor malfunctions before performing a cooling operation of the cooling system.

The control unit 1900 may check whether a temperature sensor for measuring the current temperature in the sensor unit 1600 is malfunctioning. For example, the sensor unit 1600 includes at least a first temperature sensor and a second temperature sensor, and the control unit 1900 calculates a first temperature value based on a signal obtained from the first temperature sensor and a second temperature sensor. A second temperature value is calculated based on a signal obtained from the temperature sensor, and the first temperature value and the second temperature value are compared. If the difference is greater than a preset threshold value, it may be determined that the sensor is malfunctioning.

The control unit 1900 may provide an interface related to sensor malfunction in the process of determining it. For example, referring to FIG. 7, the control unit 1900 outputs a first screen to the user through the status output unit 1840, and the first screen is a first display to indicate the current mode of the cooling device 1000. It may include an area C1 and a second display area C2 for displaying content related to sensor malfunction determination. At this time, content that guides the user to perform operations necessary to determine sensor malfunction may be displayed in the second display area C2 of the first screen.

The control unit 1900 may receive user input and determine whether the sensor is malfunctioning. For example, when receiving a trigger input through the trigger module 1720, the control unit 1900 may determine whether a sensor malfunctions by using a plurality of temperature sensors as described above.

If it is determined that the sensor is malfunctioning, the control unit 1900 may provide a notification indicating the malfunction of the sensor through the notification output unit 1820. Additionally, if it is determined that the sensor is malfunctioning, the control unit 1900 may not proceed to the next step (S220) or may turn off the power to the cooling device 1000.

If the control unit 1900 determines that the sensor is operating normally, it can proceed to the next step (S220). Meanwhile, the step (S210) of checking whether the sensor is malfunctioning can be omitted.

The control unit 1900 can set the treatment temperature and operation time (S220). The control unit 1900 can receive input from the user and set the treatment temperature and operation time.

The control unit 1900 may provide an interface for setting the treatment temperature and operation time. For example, referring to (a) of FIG. 8, the control unit 1900 outputs a second screen through the status output unit 1840, and the second screen displays numbers or shapes for setting the treatment temperature and operation time. may include a third display area C3.

The control unit 1900 may set the treatment temperature and operation time based on the signal received from the manipulation module 1740. For example, as shown in (a) of FIG. 8, the manipulation module 1740 generates a manipulation signal according to the user's rotation or pressing motion, and the control unit 1900 receives the manipulation signal from the manipulation module 1740. By obtaining the treatment temperature and operating time, you can set the treatment temperature and operation time.

Here, the value that can be set as the treatment temperature may be within a preset first temperature range. The lower limit of the first temperature range may be set between -30°C and 10°C, and the upper limit of the first temperature range may be set between -10°C and 30°C. For example, the first temperature range may be -10°C or more and 5°C or less. In the process of setting the treatment temperature, the temperature output through the status output unit 1840 may be within the first temperature range regardless of the user's operation.

A value that can be set as the operation time may be within a first preset time range. The first time range may be 0 to 120 seconds. Meanwhile, when the operation time is set to 0 seconds, an error notification may be provided through the status output unit 1840. For example, when the control unit 1900 obtains an operation signal from the operation module 1740 and sets the operation time, if the operation time is 0 seconds, an error notification can be immediately provided to the user through the status output unit 1840. there is. For another example, when the control unit 1900 obtains an operation signal from the operation module 1740 and sets the operation time, if the operation time is 0 seconds, status information to be described later is output in step S230 or the control unit 1900 An error notification may be provided in the step of controlling the temperature of the target (S260). Error notifications may be provided intermittently or continuously.

The control unit 1900 may output status information (S230). The control unit 1900 may output status information through the status output unit 1840. Here, the status information may include at least the treatment temperature, operation time, status of the cooling device 1000, real-time target temperature, and real-time operation time.

The control unit 1900 may provide an interface for outputting status information. For example, referring to (b) of FIG. 8, the control unit 1900 outputs a third screen through the status output unit 1840, and the third screen is a fourth display area for displaying the treatment temperature and operation time. (C4), a fifth display area (C5) for displaying the status of the cooling device 1000, and a sixth display area (C6) for displaying the real-time target temperature and real-time operation time. The treatment temperature and operation time displayed in the fourth display area C4 do not change unless the treatment is completed or newly set. The state of the cooling device 1000 displayed in the fifth display area C5 may be changed to indicate a state in which coolant is being sprayed while coolant movement is allowed by the flow rate controller 1400, that is, while coolant is being sprayed. You can.

The real-time temperature displayed in the sixth display area C6 may be periodically updated with a value measured through the sensor unit 1600 or a value obtained by processing the measured value. Real-time temperature is output before the coolant is sprayed on the target, so users can check the real-time temperature at any time. Meanwhile, the real-time temperature may be output from the time the coolant is sprayed on the object.

In addition, the real-time operation time displayed in the sixth display area (C6) is the time elapsed based on the time when the current temperature measured or calculated through the sensor unit 1600 reaches the treatment temperature, and the real-time operation time is preset. It can be reset when the operating time is reached. The real-time operation time may be output before or after the time when the flow rate controller 1400 is controlled to spray the coolant.

Meanwhile, unlike the above, the real-time operation time displayed in the sixth display area C6 may not be reset even if the preset operation time is reached.

In addition to outputting status information, the control unit 1900 may provide a preparation notification through a configuration different from that of the status output unit 1840. As the preparation notification is provided, the user can recognize that the cooling device 1000 is ready for use.

The control unit 1900 may determine whether the first operating condition is satisfied (S240). The first operating condition may refer to a condition for starting coolant injection from the cooling device 1000 in the cooling mode. For example, when the first operation condition is satisfied with the treatment temperature and operation time set, the controller 1900 may control the flow rate controller 1400 to spray coolant to the target.

Meanwhile, the meaning of determining whether a condition is satisfied in the following refers not only to the case where the process of determining whether the condition is satisfied is implemented separately in a program for operating the cooling device 1000, but also to the process of determining whether the condition is satisfied. It is not implemented separately in this program and can be understood as a comprehensive concept that includes all cases such as entering the second state when conditions are satisfied in the first state, or performing the next step or a specific function. For example, this means that the first operation is performed when the first condition is satisfied in the cooling device 1000. After the control program of the cooling device 1000 determines whether the first condition is satisfied, if the first condition is satisfied, the first operation is performed. This may include a case that includes source code that causes the first operation to be performed, and a case that includes source code that causes the first operation to be performed when the first condition is satisfied without a separate determination as to whether or not the first condition is satisfied.

The first operating condition may be related to a signal generated by the input unit 1700 according to the user's input.

As an example, the first operating condition may include a condition in which a trigger signal is received for a preset first time or longer. Specifically, when the control unit 1900 receives a trigger signal from the trigger module 1720 for a first time or longer as the user presses the trigger module 1720 for a first time or longer, the control unit 1900 It may be determined that the first operating condition is satisfied.

Here, the trigger signal is continuously or periodically generated by the trigger module 1720 for a first time or longer, and the control unit 1900 continuously generates a trigger signal from the trigger module 1720 for a first time or longer. Alternatively, it can be received periodically.

Additionally, the first time may be set within 0 to 5 seconds. For example, the first time may be set to 1.5 seconds. In this case, in order to spray the coolant, the user must press the trigger module 1720 for at least a certain period of time, thereby preventing accidental spraying of the coolant and improving the safety of use. More specifically, in the cooling mode, as will be described later, the coolant is sprayed when the first operating condition is satisfied and the spray of the coolant can be maintained without any separate manipulation. If the trigger module 1720 is triggered due to a user's mistake or an external factor, It is necessary to prevent the coolant from being unnecessarily sprayed when pressurized, and the first time can be set to a certain time to prevent the above-mentioned dangerous situation from occurring.

As another example, the first operating condition may include a condition in which a trigger signal is received. Specifically, when the control unit 1900 receives a trigger signal from the trigger module 1720 as the user presses the trigger module 1720, the control unit 1900 may determine that the first operation condition is satisfied.

As another example, the first operating condition may include a condition in which a specific input (eg, manipulation input, touch input, voice input, etc.) is received through the input unit 1700 in addition to the above-described trigger signal.

If the first operating condition is not satisfied, the control unit 1900 may enter the previous step (S230). Alternatively, when the control unit 1900 receives an operation signal for a preset time from the operation module 1740 while the first operation condition is not satisfied, the control unit 1900 may enter the step (S220) of setting the treatment temperature and operation time. .

Coolant may be sprayed from the cooling device 1000 (S250). For example, when the first operating condition is satisfied, the controller 1900 may control the flow rate controller 1400 (e.g., open a valve) to inject coolant. At this time, the control unit 1900 controls the flow rate controller 1400 to maintain coolant injection even if a separate trigger signal is not received after the first operating condition is satisfied (e.g., maintains the open state of the valve). You can.

The control unit 1900 can control the temperature of the object (S260). Here, the temperature of the object may mean the current temperature described above. The current temperature control and method are as follows.

1) The current temperature has reached the treatment temperature

The controller 1900 may calculate the current temperature based on the measurement signal obtained through the sensor unit 1600 and control the temperature controller 1300 so that the calculated current temperature becomes the treatment temperature. In this process, the temperature control method described above can be used.

2) The current temperature is maintained at the preset treatment temperature.

The control unit 1900 continuously or periodically obtains a measurement signal through the sensor unit 1600, and controls the temperature control unit 1300 to reduce the difference between the current temperature calculated therefrom and the preset treatment temperature. . Specifically, the control unit 1900 can change the amount of power applied to the temperature control unit 1300 according to the temperature control method described above.

The controller 1900 may perform the above-described current temperature control periodically or continuously. Additionally, the step of spraying coolant (S250) and controlling the current temperature (S260) by the control unit 1900 may be performed in parallel.

Meanwhile, the control unit 1900 may provide a notification in the step of spraying coolant (S250) and the step of controlling the current temperature (S260). Specifically, the control unit 1900 provides a notification when the current temperature measured or calculated through the sensor unit 1600 reaches the treatment temperature in the process of spraying coolant to the target, and the real-time operation time is the operation time. A reset notification can be provided at the time of reaching and resetting. The user may recognize that the current temperature has reached the treatment temperature through the arrival notification and take care not to change the position of the cooling device 1000 with respect to the subject in order to cool the subject to the treatment temperature for a certain period of time. Additionally, the user may recognize that a cooling procedure has been performed on the object once through a reset notification, and may remove the cooling device 1000 from the object and move it to another area, or perform a second cooling procedure on the same object.

Additionally, the control unit 1900 may output status information such as current temperature or operating time calculated in real time in the coolant spraying step (S250) and the current temperature controlling step (S260). The method of outputting the status information is omitted as it has already been described in the step of outputting the status information (S230).

The control unit 1900 may determine whether the first interruption condition is satisfied (S270). The first stop condition may refer to a condition for stopping the injection of coolant from the cooling device 1000 in the cooling mode. For example, the control unit 1900 may control the flow rate controller 1400 to stop the injection of the coolant when the first stop condition is satisfied while controlling the flow rate controller 1400 to inject the coolant.

The first interruption condition may be related to a signal generated by the input unit 1700 according to the user's input. At this time, the user's input regarding whether the first stopping condition is satisfied and the user's input regarding whether the above-described first operation condition is satisfied may be understood as different inputs. In other words, the control unit 1900 may start spraying the coolant based on the first user input and stop spraying the coolant based on the second user input.

As an example, the first stop condition may include a condition in which a trigger signal is received. Specifically, when the control unit 1900 receives a trigger signal from the trigger module 1720 as the user presses the trigger module 1720, the control unit 1900 may determine that the first stop condition is satisfied. In other words, the control unit 1900 can immediately stop spraying coolant according to the user's pressing operation of the trigger module 1720.

As another example, the first interruption condition may include a condition in which a trigger signal is received for a second preset time. Specifically, when the control unit 1900 receives a trigger signal from the trigger module 1720 for a second time or longer as the user presses the trigger module 1720 for a second time or longer, the control unit 1900 It can be determined that the first stopping condition is satisfied.

Here, the trigger signal is continuously or periodically generated by the trigger module 1720 for a second time or longer, and the control unit 1900 continuously generates a trigger signal from the trigger module 1720 for a second time or longer. Alternatively, it can be received periodically.

Also, here, the second time can be set within 0 to 3 seconds. Furthermore, the second time may be set shorter than the above-described first time. In this case, the process in which coolant injection is stopped may be relatively shorter than the process in which coolant injection is started.

The control unit 1900 may periodically or continuously determine whether the first stop condition is satisfied. The controller 1900 may maintain coolant injection if the first stop condition is not satisfied. Specifically, the control unit 1900 may maintain the state (e.g., open state) of the flow rate controller 1400 so that injection of the coolant is maintained if the first stopping condition is not satisfied. In other words, the controller 1900 may repeat the step of spraying the coolant (S250) and/or the step of controlling the temperature of the object (S260) until the first stopping condition is satisfied.

The step of determining whether the above-described first stopping condition is satisfied (S270) may be performed in parallel with the step of spraying the coolant (S250) and controlling the current temperature (S260).

Meanwhile, considering the above-described first operating condition and first stopping condition, the responsiveness of the cooling device 1000 to the user's action or manipulation may be relatively slower in the case of spraying the coolant than in the case of stopping the coolant.

The control unit 1900 may stop coolant injection when the first stop condition is satisfied (S280). When the first stop condition is satisfied, the controller 1900 may control the flow rate controller 1400 to stop spraying the coolant. Here, cessation of coolant injection may mean temporary cessation or termination of the procedure. In other words, after coolant injection is stopped, the control unit 1900 may enter the step of checking for sensor malfunction (S210), setting the treatment temperature and operating time (S220), or outputting status information (S230). The step of determining whether the operating conditions are satisfied (S240) may be entered and the coolant may be sprayed again when the first operating conditions are satisfied, and the operation of the cooling device 1000 may be terminated by turning off the power to the cooling device 1000. .

Some of the steps described above may be omitted, the order in which each step is performed is not limited to the order described, and additional steps may be included in addition to the steps described above.

[프리징 모드][Freezing Mode]

Hereinafter, a method of operating the cooling device 1000 in the freezing mode according to an embodiment of the present specification will be described with reference to FIGS. 9 to 11.

In the case of freezing mode, it is for a procedure that destroys the tissues contained in the target by making the target at a relatively low temperature or extremely low temperature. It is essential to ensure relative safety as it can cause irreversible damage to the target. The freezing mode described below includes different steps from the cooling mode described above, and this difference can be understood as occurring in order to ensure safety as described above.

FIG. 9 is a diagram illustrating a control method of the cooling system 100 in freezing mode according to an embodiment of the present specification.

10 and 11 are diagrams showing the status output unit 1840 of the cooling system 100 in freezing mode according to an embodiment of the present specification.

Referring to FIG. 9, the control method of the cooling system 100 in the freezing mode includes outputting a caution notification (S310), determining whether the preliminary operation conditions are satisfied (S320), and outputting a ready screen (S330). ), determining whether the second operation condition is satisfied (S340), spraying coolant (S350), outputting real-time operation time and accumulated operation time (S360), determining whether the second stop condition is satisfied It may include a step of doing so (S370), and a step of stopping coolant injection (S380).

The operation of the cooling device 1000 described in this specification may be interpreted as being performed by the control unit 1900 unless otherwise specified. Each step is described in detail below.

The control unit 1900 may output a caution notification (S310). The control unit 1900 may output a notification indicating a caution or warning through the status output unit 1840. For example, referring to FIG. 10, the control unit 1900 outputs a fourth screen through the status output unit 1840, and the fourth screen is a seventh display area to indicate the current mode of the cooling device 1000. (C7) and an eighth display area (C8) for outputting a warning message.

The control unit 1900 may determine whether the preliminary operation condition is satisfied (S320). Preliminary operating conditions can be understood as conditions for completing preparation for coolant injection. Unless the preliminary operating conditions are satisfied, the coolant may not be sprayed from the cooling device 1000 even if there is a user's input or manipulation.

The preliminary operating condition may be related to a signal generated by the input unit 1700 according to the user's input.

As an example, the preliminary operating condition may include a condition in which an operation signal is received for a preset third time or longer. Specifically, when the control unit 1900 receives a manipulation signal from the manipulation module 1740 for a third time or longer as the user presses the manipulation module 1740 for a third time or longer, the control unit 1900 It can be determined that the preliminary operation conditions are satisfied.

Here, the manipulation signal is continuously or periodically generated by the manipulation module 1740 for a third time or longer, and the control unit 1900 continuously generates a manipulation signal from the manipulation module 1740 for a third time or longer. Alternatively, it can be received periodically.

Additionally, the third time can be set within 0 to 5 seconds. Accordingly, in order to make the cooling device 1000 ready for coolant injection, the user must perform a preparatory operation of pressing the manipulation module 1740 for at least a certain period of time.

As another example, the preliminary operating condition may include a condition under which an operating signal is received. Specifically, when the control unit 1900 receives a manipulation signal from the manipulation module 1740 as the user presses the manipulation module 1740, the controller 1900 may determine that the preliminary operation condition is satisfied.

As another example, the preliminary operation condition may include a condition in which a specific input (ex. manipulation input, touch input, voice input, etc.) is received through the input unit 1700 in addition to the above-described trigger signal.

The control unit 1900 may output a ready screen (S330). When the preliminary operation conditions are met, the control unit 1900 may output a ready screen through the status output unit 1840. For example, referring to FIG. 11, the control unit 1900 outputs a fifth screen through the status output unit 1840, and the fifth screen includes a ninth display area C9 for displaying real-time operation time and a cumulative display area C9. It may include a tenth display area C10 for displaying the operating time. Methods for displaying real-time operation time and accumulated operation time will be described later.

The control unit 1900 may determine whether the second operating condition is satisfied (S340). The second operating condition may refer to a condition for starting coolant injection from the cooling device 1000 in freezing mode. For example, when the second operating condition is satisfied while the ready screen is output through the status output unit 1840, the control unit 1900 may control the flow rate controller 1400 to spray coolant to the target.

The second operating condition may be related to a signal generated by the input unit 1700 according to the user's input.

As an example, the second operating condition may include a condition in which a trigger signal is received. Specifically, when the control unit 1900 receives a trigger signal from the trigger module 1720 as the user presses the trigger module 1720, the control unit 1900 may determine that the second operation condition is satisfied.

As another example, the second operating condition may include a condition in which a trigger signal is received for a preset fourth time or longer. Specifically, when the control unit 1900 receives a trigger signal from the trigger module 1720 for the fourth time or more as the user presses the trigger module 1720 for the fourth time or more, the control unit 1900 It may be determined that the second operating condition is satisfied.

Here, the trigger signal is continuously or periodically generated by the trigger module 1720 for the fourth time or more, and the control unit 1900 continuously generates the trigger signal from the trigger module 1720 for the fourth time or more. Alternatively, it can be received periodically.

Additionally, the fourth time can be set within 0 to 5 seconds.

As another example, the second operating condition may include a condition in which a specific input (ex. manipulation input, touch input, voice input, etc.) is received through the input unit 1700 in addition to the above-described trigger signal.

If the second operation condition is not satisfied, the control unit 1900 may maintain the ready screen output. Alternatively, the control unit 1900 may enter the step (S310) of outputting a caution notification if the second operating condition is not satisfied within a certain time.

The control unit 1900 can spray coolant when the second operating condition is satisfied (S350). When the second operating condition is satisfied, the controller 1900 can control the flow rate controller 1400 to spray coolant.

In the freezing mode, unlike the cooling mode, the step (S260) of controlling the temperature of the object can be omitted. In other words, in the freezing mode, the controller 1900 may not provide heat energy to the coolant using the temperature controller 1600. Through this, the coolant sprayed on the object in freezing mode only expands without supplying heat energy and can have a very low temperature. Alternatively, in the freezing mode, the control unit 1900 may minimize the heat energy provided to the coolant by setting the power applied to the temperature control unit 1600 below a preset minimum value.

The control unit 1900 can output the real-time operation time and accumulated operation time (S360). The control unit 1900 can output real-time operation time and accumulated operation time through the status output unit 1840. Specifically, referring to FIG. 11, the control unit 1900 outputs the fifth screen including the ninth display area and the tenth display area through the status output unit 1840, and displays the real-time operation time in the ninth display area. , the cumulative operation time can be displayed in the tenth display area.

The cumulative operating time may refer to the total time during which coolant is sprayed from the cooling device 1000. For example, as described later, when the control unit 1900 injects coolant only when a trigger signal is received, the control unit 1900 may obtain the total time for receiving the trigger signal causing coolant injection as the cumulative operation time. You can. For another example, the cooling device 1000 may calculate the cumulative operation time by using a timer to measure the time from when the coolant is injected to when the coolant injection is stopped.

As described above, unlike the cooling mode, in the freezing mode, the cumulative operation time in addition to the real-time operation time may be displayed through the status output unit 1840. In this way, as the cumulative operation time is further displayed, the user can recognize the total time the coolant has been sprayed on the target, whether the target has suffered irreversible damage from the coolant spray, or whether there is a risk of continuing the procedure, etc. It is possible to judge, and as a result, whether to continue or terminate the procedure. On the other hand, in the case of cooling mode, the cumulative operation time does not necessarily need to be displayed because the temperature of the coolant sprayed on the object is controlled and does not cause irreversible damage.

The control unit 1900 may determine whether the second interruption condition is satisfied (S370). The second stop condition may mean a condition for stopping the injection of coolant from the cooling device 1000 in freezing mode. For example, the control unit 1900 may control the flow rate controller 1400 to stop the injection of the coolant when the second stop condition is satisfied while controlling the flow rate controller 1400 to inject the coolant.

The second interruption condition may be related to a signal generated by the input unit 1700 according to the user's input. At this time, the user's input regarding whether the second stop condition is satisfied and the user's input regarding whether the above-described second operation condition is satisfied may be the same input. In other words, the control unit 1900 may start spraying the coolant based on the third user input and stop spraying the coolant based on the third user input.

As an example, the second interruption condition may include a condition in which reception of the trigger signal is not maintained. Specifically, when the first operation condition is satisfied by the user pressing the trigger module 1720 and the control unit 1900 receiving a trigger signal, the user stops pressing the trigger module 1720 and the control unit 1900 When the trigger signal is no longer received, the control unit 1900 may determine that the second stop condition is satisfied. In other words, the control unit 1900 may immediately stop spraying coolant when the user input to the trigger module 1720 for the second operating condition is removed.

As another example, the second interruption condition may include a condition in which a preset threshold time elapses. Specifically, the control unit 1900 may stop spraying the coolant when a critical time has elapsed based on the time when the coolant was sprayed. In other words, when the real-time operation time exceeds the critical time, the controller 1900 determines that the second stop condition is satisfied and controls the flow rate controller 1400 to stop spraying the coolant.

As another example, the second interruption condition may include both the above-described reception maintenance condition and the threshold time condition of the trigger signal. The controller 1900 may control the flow rate controller 1400 to stop spraying the coolant when one of the two conditions is satisfied.

As another example, the second interruption condition may include a condition in which a specific input (ex. manipulation input, touch input, voice input, etc.) is received through the input unit 1700 in addition to the above-described trigger signal.

If the second interruption condition is not satisfied, the controller 1900 may control the flow rate controller 1400 or maintain the state (e.g., open state) of the flow rate controller 1400 to continue spraying the coolant.

The control unit 1900 may stop coolant injection when the second stop condition is satisfied (S380). When the second stop condition is satisfied, the controller 1900 may control the flow rate controller 1400 to stop spraying the coolant. Here, cessation of coolant injection may mean temporary cessation or termination of the procedure. In other words, after coolant injection is stopped, the control unit 1900 may enter the step of outputting a caution notification (S310) or the step of outputting a ready screen (S330), and determine whether the second operation condition is satisfied. When step S340 is entered and the second operating condition is satisfied, the coolant may be sprayed again, and the operation of the cooling device 1000 may be terminated by turning off the power of the cooling device 1000.

As the above-described steps are performed in freezing mode, the safety of the patient during the procedure can be ensured. For example, in freezing mode, if the cooling device 1000 is not ready (e.g., does not enter the ready screen output step (S330)), spraying of cryogenic coolant is prevented, thereby preventing unintended coolant from being sprayed. Spraying can be prevented. In addition, the coolant is sprayed only while the user's trigger input exists, and when the user's trigger input is removed, the coolant is sprayed, so the coolant can be sprayed only for the time desired by the user.

[부스팅 모드][Boosting Mode]

Hereinafter, a method of operating the cooling device 1000 in the boosting mode according to an embodiment of the present specification will be described with reference to FIGS. 12 and 13.

As described above, the boosting mode refers to a control method of the cooling device 1000 when the coolant and the composition are sprayed together. Here, the composition is a concept that encompasses not only pharmaceutical compositions used for medical treatment purposes but also cosmetic compositions used for cosmetic purposes, and may refer to substances containing active ingredients that induce or generate medical or cosmetic effects.

At this time, the cooling system 100 may further include a composition injection module.

The composition injection module can be attached and detached to the cooling device 1000. Specifically, the composition injection module can be attached and detached to the nozzle 1100 of the cooling device 1000. For example, the composition injection module includes a nozzle coupling portion, and the nozzle coupling portion of the composition injection module and the nozzle 1100 may be coupled through interference fit coupling, hook coupling, magnetic coupling, etc.

The composition injection module may include a hollow tube. The hollow pipe may include an insertion portion into which the nozzle is inserted and a composition inlet portion into which the composition flows. In other words, the hollow pipe can be understood as a space where the coolant sprayed from the nozzle and the composition flowing into the composition inlet meet.

The composition dispensing module can contain the composition. For example, the composition dispensing module may include a composition container in which the composition is stored. The composition container may be provided with an external air inlet hole through which external air can be introduced.

The composition container and the hollow tube may be fluidly connected. For example, the composition injection module includes a composition moving pipe, and the composition moving pipe may fluidly connect the composition container and the hollow pipe. At this time, the composition stored in the composition container can be moved to the hollow pipe through the composition transfer pipe.

The composition may be sprayed together by spraying coolant from the composition spray module. Specifically, when the coolant is injected through the hollow pipe of the composition injection module, a negative pressure is formed at the composition inlet according to Bernoulli's principle, and the composition in the composition container is caused by the outside air flowing in through the outside air inlet hole formed in the composition container. This pressure allows the composition to move into the hollow tube. The composition flowing into the hollow pipe may collide with the injected coolant and be sprayed out of the composition injection module along with the coolant.

Hereinafter, the boosting mode, which is a method in which the cooling device 1000 is controlled when the composition and coolant are sprayed together in a state where the composition injection module is mounted on the cooling device 1000, will be described.

FIG. 12 is a diagram illustrating the operation of the cooling system 100 in a boosting mode according to an embodiment.

FIG. 13 is a diagram for explaining the status output unit 1840 of the cooling system 100 in the boosting mode according to an embodiment. Figure 13(a) is a diagram showing a guide being displayed on the status output unit 1840, and Figure 13(b) is a diagram showing a ready screen being displayed.

Referring to FIG. 12, the control method of the cooling system 100 in the boosting mode includes outputting a guide (S410), determining whether the preliminary operation conditions are satisfied (S420), and outputting a ready screen (S430). , determining whether the third operating condition is satisfied (S440), spraying the coolant and the composition (S450), determining whether the third stopping condition is satisfied (S460), and stopping the spraying of the coolant and the composition. It may include step S470.

The control unit 1900 can output a guide (S410). The control unit 1900 may display a guide through the status output unit 1840. For example, referring to (a) of FIG. 13, the control unit 1900 outputs the sixth screen through the status output unit 1840, and the sixth screen indicates the current mode and provides a guide for checking the installation of the composition injection module. It may include an 11th display area C11 for display. The user can confirm that the composition injection module is properly mounted on the cooling device 1000 by looking at the guide displayed on the status output unit 1840.

The control unit 1900 may determine whether the preliminary operation condition is satisfied (S420). Preliminary operating conditions may be understood as conditions for completing preparation for injection of coolant and composition. Unless the preliminary operating conditions are satisfied, the coolant or composition may not be sprayed from the cooling device 1000 even if there is a user's input or manipulation. This step S420 may be the same as the previously described step S320, and the preliminary operating conditions may also be understood as the same as the conditions described in step S320.

The control unit 1900 may output a ready screen (S430). When the preliminary operation conditions are met, the control unit 1900 may output a ready screen through the status output unit 1840. For example, referring to (b) of FIG. 13, the control unit 1900 outputs the seventh screen through the status output unit 1840, and the seventh screen is a twelfth display area (C12) to display the ready state. ), a 13th display area C13 for displaying the current mode, and a 14th display area C14 for displaying the spraying method.

The control unit 1900 may determine whether the third operating condition is satisfied (S440). The third operating condition may refer to a condition for starting spraying of the coolant and composition from the cooling device 1000 in the boosting mode. For example, when the third operation condition is satisfied while the ready screen is output through the status output unit 1840, the control unit 1900 can control the flow rate controller 1400 to spray coolant to the target, As the coolant is sprayed, the composition may be sprayed together.

The third operating condition may be related to a signal generated by the input unit 1700 according to the user's input.

As an example, the third operating condition may include a condition in which a trigger signal is received. Specifically, when the control unit 1900 receives a trigger signal from the trigger module 1720 as the user presses the trigger module 1720, the control unit 1900 may determine that the third operation condition is satisfied.

As another example, the third operating condition may include a condition in which a trigger signal is received for a preset fifth time or longer. Specifically, when the control unit 1900 receives a trigger signal from the trigger module 1720 for the fifth time or more as the user presses the trigger module 1720 for the fifth time or more, the control unit 1900 It can be determined that the third operation condition is satisfied.

Here, the trigger signal is continuously or periodically generated by the trigger module 1720 for the fifth time or more, and the control unit 1900 continuously generates the trigger signal from the trigger module 1720 for the fifth time or more. Alternatively, it can be received periodically.

Additionally, the fifth time can be set within 0 to 5 seconds.

As another example, the third operating condition may include a condition in which a specific input (eg, manipulation input, touch input, voice input, etc.) is received through the input unit 1700 in addition to the above-described trigger signal.

If the third operation condition is not satisfied, the control unit 1900 may maintain the ready screen output. Alternatively, the control unit 1900 may enter the step (S410) of outputting a guide if the third operating condition is not satisfied within a certain time.

The control unit 1900 may spray the coolant and composition when the third operating condition is satisfied (S450). When the third operating condition is satisfied, the control unit 1900 controls the flow rate control unit 1400 to spray coolant, and the composition can be sprayed by spraying the coolant.

In the boosting mode, unlike the cooling mode, the step (S260) of controlling the temperature of the target can be omitted. In other words, in the boosting mode, the controller 1900 can provide a certain level (or constant value) of heat energy to the coolant using the temperature controller 1600. Through this, the coolant sprayed to the target in boosting mode can be controlled within a certain temperature range while receiving only a certain amount of heat energy.

Meanwhile, in boosting mode, the temperature of the target can be controlled in the same way as in cooling mode. For example, as described in step S260, the control unit 1900 may apply heat energy to the coolant using the temperature control unit 16000 so that the temperature of the object becomes a preset target temperature.

While the coolant and composition are being sprayed, the status output unit 1840 may display that the coolant and composition are being sprayed. Additionally, the status output unit 1840 may display the time at which the coolant and composition were sprayed, the sprayable time for spraying, the remaining sprayable time, or the temperature of the target. Here, the sprayable time may mean the time during which spraying of at least one of the composition or the coolant can continue continuously. The sprayable time may be proportional to the amount of coolant or composition. For example, the sprayable time may be about 3 minutes.

The control unit 1900 may determine whether the third interruption condition is satisfied (S460). The third stopping condition may mean a condition for stopping the spraying of the coolant and composition from the cooling device 1000 in the boosting mode. For example, the control unit 1900 may control the flow rate controller 1400 to stop the injection of the coolant when the third stop condition is satisfied while controlling the flow rate controller 1400 to inject the coolant.

The third interruption condition may be related to a signal generated by the input unit 1700 according to the user's input. At this time, the user's input regarding whether the third interruption condition is satisfied and the user's input regarding whether the above-mentioned third operation condition is satisfied may be the same input. In other words, the control unit 1900 may start spraying the coolant based on the fourth user input and stop spraying the coolant based on the fourth user input.

As an example, the third stop condition may include a condition in which a trigger signal is received. Specifically, when the control unit 1900 receives a trigger signal from the trigger module 1720 as the user presses the trigger module 1720, the control unit 1900 may determine that the third stop condition is satisfied. In other words, the control unit 1900 can immediately stop spraying coolant according to the user's pressing operation of the trigger module 1720.

As another example, the third interruption condition may include a condition in which a trigger signal is received for a preset sixth time. Specifically, when the control unit 1900 receives a trigger signal from the trigger module 1720 for the sixth time or more as the user presses the trigger module 1720 for the sixth time or more, the control unit 1900 It can be determined that the third stopping condition is satisfied.

Here, the trigger signal is continuously or periodically generated by the trigger module 1720 for the sixth time or more, and the control unit 1900 continuously generates the trigger signal from the trigger module 1720 for the sixth time or more. Alternatively, it can be received periodically.

Also, here, the sixth time can be set within 0 to 3 seconds. Furthermore, the sixth time may be set shorter than the aforementioned fifth time. In this case, the process in which spraying of the coolant and composition is stopped may be relatively shorter than the process in which spraying of the coolant and composition is started.

As another example, the third interruption condition may include a condition in which a specific input (ex. manipulation input, touch input, voice input, etc.) is received through the input unit 1700 in addition to the above-described trigger signal.

The control unit 1900 may periodically or continuously determine whether the third interruption condition is satisfied. The control unit 1900 may maintain spraying of the coolant and composition if the third stopping condition is not satisfied. Specifically, the control unit 1900 may maintain the state (e.g., open state) of the flow rate controller 1400 so that injection of the coolant and composition is maintained if the third stopping condition is not satisfied. In other words, the control unit 1900 may repeat the step (S450) of spraying the coolant and composition described above until the third stopping condition is satisfied.

The step of determining whether the above-described third stopping condition is satisfied (S460) may be performed in parallel with the step of spraying the coolant and composition (S450).

The control unit 1900 may stop coolant injection when the third stop condition is satisfied (S470). When the third stop condition is satisfied, the controller 1900 may control the flow rate controller 1400 to stop spraying the coolant and composition. Here, cessation of injection of coolant and composition may mean temporary cessation or termination of the procedure. In other words, after the injection of the coolant and composition is stopped, the control unit 1900 may enter the step of outputting a guide (S410) or the step of outputting a ready screen (S430) and determine whether the third operation condition is satisfied. The judgment step (S440) may be entered, and when the third operating condition is satisfied, the coolant and composition may be sprayed again, and the operation of the cooling device 1000 may be terminated by turning off the power of the cooling device 1000.

The control method of the cooling device 1000 in the above-described boosting mode can be understood as being intended to ensure continuity of the procedure. For example, when it is desired to spray a composition by dividing a relatively large area into a plurality of areas, the composition can be sprayed continuously by using the cooling device 1000 in boosting mode, and thus the composition can be sprayed on all areas. It can be sprayed densely or tightly.

Hereinafter, with reference to FIGS. 14 and 15, the differences between the operating method for spraying coolant in cooling mode, the operating method for spraying coolant in freezing mode, and the operating method for spraying coolant and composition in boosting mode will be discussed. Describe about it.

FIG. 14 is a diagram illustrating an operation process of the cooling device 1000 in a cooling mode and a freezing mode according to an embodiment. FIG. 15 is a diagram for explaining the operation of the cooling system 100 according to a trigger input in a boosting mode according to an embodiment. FIGS. 14 and 15 are diagrams to explain how the components of the cooling device 1000 are controlled in the process of spraying coolant, and it can be understood that steps before spraying coolant have already been performed or are omitted. For example, in FIG. 14, in the case of the cooling mode, the cooling device 1000 is in a state until the status information output step (S230), and in the freezing mode, the cooling device 1000 is in a state until the ready screen output step (S330). It may be in a performed state. Additionally, in the case of the boosting mode in FIG. 15, the cooling device 1000 may be in a state that has been performed up to the ready screen output step (S430).

Meanwhile, in FIGS. 14 and 15 , the flow rate controller 1400 is described as a valve for convenience of explanation, but the technical idea of the present specification is not limited thereto. Additionally, in FIG. 14, for convenience of explanation, the first operating condition of the cooling mode is a condition in which a trigger signal is received for a preset first time (CT1) or longer, and the first stop condition in the cooling mode is a condition in which a trigger signal is received. This is a condition in which the second operating condition of the freezing mode is a condition in which a trigger signal is received, and the second stop condition in the freezing mode is a condition in which reception of the trigger signal is not maintained or a condition in which the threshold time elapses. Although mainly described, the technical idea of the present specification is not limited thereto, and each condition may be determined in various ways as described above. Similarly, in FIG. 15, for convenience of explanation, the third operating condition of the boosting mode is a condition under which a trigger signal is received, and the third stop condition of the boosting mode is also mainly described as a condition under which a trigger signal is received. However, in the present specification The technical idea is not limited to this, and each condition can be determined in various ways as described above.

Referring to FIG. 14, in the cooling mode, the first trigger input (TR1) by the user occurs at the first time point (TP1), the first trigger input (TR1) is maintained until the second time point (TP2), and the third time point The second trigger input (TR2) may be generated at (TP3) and the second trigger input (TR2) may be maintained until the fourth time point (TP4).

The control unit 1900 operates a timer when receiving the first trigger signal according to the first trigger input TR1, and opens the valve when the first trigger signal is continuously generated or maintained for the first time CT1, thereby cooling. Coolant may be sprayed from device 1000. The control unit 1900 may also provide a first notification through the notification output unit 1820 when the first trigger signal is continuously generated or maintained during the first time CT1. Here, the first notification can be understood as a start notification.

The control unit 1900 maintains the open state of the valve even if the first trigger input TR1 is removed at the second time point TP2 and the first trigger signal is no longer received, and injection of the coolant can be maintained accordingly. .

The control unit 1900 sends a second notification through the notification output unit 1820 when the current temperature obtained using the sensor unit 1600 while the coolant is sprayed and the predetermined treatment temperature are the same or the difference is within a preset range. can be provided. Here, the second notification can be understood as the aforementioned arrival notification, and the user can recognize that the current temperature has reached the treatment temperature through the second notification.

The control unit 1900 provides a third notification through the notification output unit 1820 when the operating time is the time for which the current temperature obtained using the sensor unit 1600 is maintained within a certain range from the treatment temperature while the coolant is sprayed. can do. Here, the third notification can be understood as the above-mentioned reset notification, and the user recognizes that a treatment on the subject (e.g., a treatment for maintaining the temperature of the subject at a specific temperature for a specific time) has been completed once through the third notification. You can.

The first to third notifications described above may be provided in different ways (e.g. different sounds, different output devices, etc.). Alternatively, the first to third notifications may be provided in the same manner. Additionally, any one of the first to third notifications may be omitted.

When the control unit 1900 receives the third trigger signal according to the third trigger input TR3, the control unit 1900 may close the valve, thereby stopping the injection of the coolant.

The operation method of the cooling device 1000 described above in the cooling mode can be understood as ensuring continuity of procedures using the cooling device 1000. For example, in a procedure in which a relatively large area is divided into a plurality of areas and the drug is injected in each area, but a coolant is sprayed before drug injection to relieve pain, the cooling procedure can be performed by using the cooling device 1000 in the cooling mode. This can be performed continuously, so the total procedure time can be effectively reduced. Specifically, when the cooling procedure and drug injection are performed on the second region after the cooling procedure and drug injection are performed on the first region among the treatment areas, the user uses the cooling device 1000 operating in the cooling mode. The cooling device 1000 may be moved from the first area to the second area while spraying the coolant is maintained. At this time, the cooling device 1000 operating in the cooling mode continues to spray coolant unless there is a separate user input (e.g. trigger input), enabling continuous treatment on the first and second areas.

Additionally, the operation of the cooling device 1000 according to the operation method of the cooling device 1000 described above in the cooling mode can be understood as being intended to ensure uniformity and accuracy of procedures using the cooling device 1000. In the above-mentioned drug injection procedure, according to the notification provided by the cooling device 1000, the user recognizes that the cooling procedure for the first area is completed, injects the drug, and then moves the cooling device 1000 to the second area. You can. In other words, the accuracy of the cooling procedure is ensured in that the cooling device 1000 maintains the first area having a specific temperature before drug injection for a specific time, and both the first area and the second area are cooled under the same conditions. As the procedure is performed, uniformity of the cooling procedure can be secured. Ensuring such uniformity is essential not only for cooling anesthesia but also for cooling procedures for whitening.

Referring again to FIG. 14, in the freezing mode, the third trigger input (TR3) by the user occurs at the fifth time point (TP5), the third trigger input (TR3) is maintained until the sixth time point (TP6), and the third trigger input (TR3) is maintained until the sixth time point (TP6). The fourth trigger input TR4 may be generated at the 7th time point TP3 and maintained until the 8th time point TP8.

When the control unit 1900 receives the third trigger signal according to the third trigger input TR3, it opens the valve, thereby allowing the coolant to be sprayed from the cooling device 1000. The control unit 1900 may also monitor whether the threshold time has elapsed by operating a timer at the fifth time point TP5 when the third trigger signal according to the third trigger input TR3 is received. Additionally, the control unit 1900 may provide a fourth notification through the notification output unit 1820 when receiving a third trigger signal according to the third trigger input TR3. Here, the fourth notification may be provided at a preset notification period (ex. 0.5 seconds, 1 second, 2 seconds, 3 seconds, 4 seconds, or 5 seconds, etc.), and periodically notifies that cryogenic coolant is being sprayed. It can be understood as a reminder to give.

The control unit 1900 may close the valve when the third trigger input TR3 is removed, thereby stopping injection of coolant. Specifically, the control unit 1900 may close the valve when the third trigger signal according to the third trigger input TR3 is not received. As a result, injection of the coolant may be stopped at substantially the same time as the sixth time point TP6 when the third trigger input TR3 is removed, and as a result, the coolant may be injected only upon the user's trigger input.

The control unit 1900 may open the valve when receiving the fourth trigger signal according to the fourth trigger input TR4. As described above, when the control unit 1900 receives the fourth trigger signal according to the fourth trigger input TR4, it can operate a timer and monitor whether the threshold time has elapsed. Additionally, when the control unit 1900 receives the fourth trigger signal according to the fourth trigger input TR4, it may provide the above-described fourth notification through the notification output unit 1820.

The control unit 1900 may close the valve when a critical time has elapsed from the seventh time point TP7 at which the fourth trigger signal according to the fourth trigger input TR4 is received, thereby stopping coolant injection. At this time, even if the fourth trigger input TR4 is maintained after the critical time has elapsed from the seventh time point TP7 and the control unit 1900 receives the fourth trigger signal, the valve may not be opened again. As a result, the longest period during which coolant injection is maintained in freezing mode can be understood as the critical time.

The operation method of the cooling device 1000 described above in the freezing mode can be understood to ensure the safety and usability of procedures using the cooling device 1000. Specifically, in the freezing mode, the temperature of the coolant sprayed from the cooling device 1000 is very low (ex. about -70°C to -50°C), so unlike the cooling mode, excessive cooling of the object and the user Unintentional injection of coolant needs to be prevented. In the above-described freezing mode, the control method in which coolant is sprayed only upon the user's trigger input is intended to immediately reflect the user's intention for coolant spray, and the control method in which the maximum time of coolant spray is limited to a critical time is used by the user to It can be understood that it is to ensure the safety of.

Meanwhile, when the above-described first and second trigger inputs (TR1, TR2) are received in freezing mode, the first trigger input (TR1) ends from the first time point (TP1) at which the first trigger input (TR1) occurs. The valve is opened and the coolant is injected until the second time point (TP2), and similarly, from the third time point (TP3) when the second trigger input (TR2) occurs to the fourth time point (TP4) when the second trigger input (TR2) ends. The valve is opened until the coolant can be sprayed.

On the other hand, when the above-mentioned third and fourth trigger inputs TR3 and TR4 are received in the cooling mode, the first time (CT1) has elapsed from the fifth time point (TP5) at which the third trigger input (TR3) occurred. From then on, the valve may be opened and closed at the seventh time point TP7 when the fourth trigger input TR4 is received.

Referring to FIG. 15, in the boosting mode, the fifth trigger input (TR5) by the user occurs at the ninth time point (TP9), the fifth trigger input (TR5) is maintained until the tenth time point (TP10), and the fifth trigger input (TR5) is maintained at the eleventh time point (TP10). The sixth trigger input (TR6) may be generated at (TP11), and the sixth trigger input (TR6) may be maintained until the twelfth time point (TP12).

When the control unit 1900 receives the fifth trigger signal according to the fifth trigger input TR5, it opens the valve, thereby allowing the coolant and composition to be sprayed from the cooling device 1000. Additionally, the control unit 1900 may provide a fifth notification through the notification output unit 1820 when receiving the fifth trigger signal according to the fifth trigger input TR5. Here, the fifth notification may be of a different type from the first to fourth notifications. The fifth notification can be understood as a notification to notify that injection of the coolant and composition has begun. A sixth notification may be output when the injection-enabled time elapses from the ninth time point TP9 when the fifth trigger input TR5 is received or when the fifth notification is output.

The control unit 1900 may close the valve at the 11th time point TP11 upon receiving the sixth trigger signal according to the sixth trigger input TR6, thereby stopping the injection of the coolant and composition.

The operation method of the cooling device 1000 described above in the boosting mode can be understood as being intended to utilize the cooling device 1000 for a set period of time along with continuity of procedures using the cooling device 1000. As described above, in the boosting mode, the composition may be sprayed by spraying the coolant, and if the coolant is used up, the composition cannot be sprayed. Conversely, if the composition is used up, only the coolant may be sprayed. To prevent this situation, the user needs to be aware of the sprayable time when the composition or coolant is all consumed. The above-described operation method can enable the user to recognize the possible injection time.

In this way, even with the same trigger input, the coolant may be sprayed in a completely different way depending on the operation mode of the cooling device 1000.

In the above, for convenience of explanation, cooling mode, freezing mode, and boosting mode were used as terms to name different types of modes. However, this is only to express different control methods, and the terms refer to the type of mode. It is not necessarily limited to cooling mode, freezing mode, and boosting mode. For example, of course, the cooling mode may be referred to as a first mode, the freezing mode may be referred to as a second mode, and the boosting mode may be referred to as a third mode. Additionally, the cooling device 1000 may operate in modes other than the cooling mode, freezing mode, and boosting mode described above, and the cooling device 1000 may operate in only one of the cooling mode, freezing mode, and boosting mode. It might work.

[모드 인식 방법][Mode recognition method]

Hereinafter, with reference to FIGS. 16 to 19, how cooling mode, freezing mode, and boosting mode are distinguished will be described.

As described above, the cooling device 1000 may operate in a cooling mode, freezing mode, or boosting mode, and may have a structure or additional components to distinguish between these modes.

For example, the mode in which the cooling device 1000 operates may be determined depending on the structure of the nozzle 1100 that can be attached or detached from the cooling device 1000. Specifically, the cooling device 1000 includes a mode recognition unit, as will be described later, and the mode recognition unit may or may not operate depending on the type of nozzle 1100 coupled to the cooling device 1000. ) can determine the mode based on whether the mode recognition unit is operating.

Before describing how the modes are classified, the structure of the nozzle 1100 will be described with reference to FIGS. 16 and 17.

Figure 16 is a diagram showing a nozzle 1100 according to an embodiment of the present specification.

Referring to FIG. 16, the nozzle 1100 may include a body 1110, an injection unit 1120, a sealing member 1130, and a filter 1140.

The body 1110 can accommodate the injection unit 1120. The body 1110 may be coupled to the nozzle coupling portion 1200 of the cooling device 1000. At this time, the mode in which the cooling device 1000 operates may be determined depending on the shape of the body 1110 when the nozzle 1100 is coupled to the cooling device 1000 through the nozzle coupling portion 1200. The shape of the body 1110 and the resulting mode determination of the cooling device 1000 will be described later.

The spray unit 1120 can spray coolant. Specifically, the injection unit 1120 includes an injection port 1121, and the coolant may be injected through the injection port 1121. The injection unit 1120 extends from one end to the other end to form a flow path, and may include a portion where the width of the flow path is relatively narrow. As the coolant passes through a relatively narrow portion of the spray portion 1120, its pressure decreases and it expands, and as a result, it can be sprayed at high speed. At this time, the coolant passes through the injection unit 1120 and undergoes the Joule-Thomson effect (Joule-Thomson effect is a phenomenon in which the temperature drops when compressed gas expands, and the temperature of the material is composed of pressure-temperature). It can be cooled and sprayed by (applied to liquefy air or cool it through a refrigerant by using the point that changes depending on the thermodynamic phase) or by adiabatic expansion.

In the cooling mode, the coolant may receive heat from the temperature control unit 1300 described above before passing through the spray unit 1120, and the coolant may receive heat based on the amount of heat energy provided from the temperature control unit 1300 and the Joule-Thomson effect. Thus, the temperature of the injected coolant can be adjusted.

In freezing mode, the coolant may not receive heat from the temperature control unit 1300 or may receive a relatively small amount of heat before passing through the spray unit 1120. In this case, the coolant being sprayed may have a cryogenic temperature (ex. It may have a temperature of about -70°C to -50°C.

The sealing member 1130 can prevent coolant from leaking. Specifically, it is possible to prevent coolant from leaking while the coolant flows from the cooling device 1000 to the injection unit 1120.

The sealing member 1130 may secure the spray unit 1120 to the body 1110. Specifically, referring to (b) of FIG. 16, when the injection unit 1120 is inserted into the body 1110, the sealing member 1130 presses the injection unit 1120 and presses it into the body 1110. can be combined

The sealing member 1130 may be made of materials such as plastic, acrylic, aluminum, Teflon, or Nylon 6 (Nylon 6-6).

The filter 1140 can filter out foreign substances contained in the coolant. The filter 1140 may serve to filter out foreign substances contained in the coolant before the coolant is sprayed to the outside through the nozzle 1100.

Referring to FIG. 16, the filter 1140 may be disposed between the spray unit 1120 and the sealing member 1130. Specifically, the filter 1140 may be damaged by coolant injection when located near the injection port 1121 of the injection unit 1120, and may be difficult to fix when located in the second groove of the sealing member 1130, which will be described later. Insofar as possible, it is preferable to be disposed between the injection unit 1120 and the sealing member 1130.

The size of the filter 1140 may be determined according to the size of the first groove of the sealing member 1130, which will be described later. For example, the diameter of the filter 1140 may be larger than the diameter of the first groove of the sealing member 1130, but may be smaller than the diameter of the sealing member 1130. For another example, the diameter of the filter 1140 may correspond to the diameter of the first groove of the sealing member 1130, which will be described later. For another example, the diameter of the filter 1140 is smaller than the diameter of the first groove of the sealing member 1130, which will be described later, but is defined by the diameter of the flow path defined by the injection unit 1120 or the sealing member 1130. It may be larger than the diameter of the flow path.

The material of the filter 1140 may be a metal material such as stainless steel or nickel.

The filter 1140 may be implemented in the form of a mesh network. For example, the filter 1140 may be in the form of a network including a plurality of pores of a preset size.

Figure 17 is a diagram showing the body 1110 according to an embodiment of the present specification.

Referring to (a) of FIG. 17, the body 1110 may be divided into at least a first part (P1), a second part (P2), and a third part (P3).

An injection unit 1120 may be disposed in the first part P1 of the body 1110. The length of the first part P1 may vary depending on the type of nozzle 1100. For example, the length of the spray unit 1120 may vary depending on the type of nozzle 1100, and the length of the first part P1 may be determined depending on the length of the spray unit 1120.

A sealing member 1130 may be disposed in the second portion P2 of the body 1110.

The third portion P3 of the body 1110 may be coupled to the nozzle coupling portion 1200 of the cooling device 1000. Specifically, the third part P3 may include a coupling means (e.g., a thread, a magnet, or a locking member such as a hook) corresponding to the nozzle coupling portion 1200. The shape of the third part P3 of the body 1110 may vary depending on the type of nozzle 1100.

The shape of the body 1110 may have different shapes depending on the type of nozzle 1100. In other words, different types of nozzles 1100 may have bodies 1110 of different shapes.

Here, the type of nozzle 1100 may be classified according to the length of the nozzle 1100 in appearance. At this time, the longer the length of the nozzle 1100, the closer the distance between the injection port 1121 of the nozzle 1100 through which the coolant is sprayed and the target. The closer the distance from the point where the coolant is sprayed to the target, the closer the coolant reaches the target. The temperature may be lowered. Additionally, as the distance from the point where the coolant is sprayed to the target increases, the temperature of the coolant reaching the target may increase, and in addition, temperature control of the coolant may become easier.

In other words, the range of temperature of the object to be controlled may vary depending on the type of nozzle 1100, and as described later, the cooling device 1000 may operate depending on the type of procedure to be performed using the cooling system 100. The type of nozzle 1100 to be used may be determined.

Hereinafter, for convenience of explanation, the case where the nozzle 1100 is classified into a cooling nozzle or a freezing nozzle depending on the type is mainly described, but this is used as a term to name different types of nozzles, and the nozzle 1100 The term referring to the type is not necessarily limited to cooling nozzles and freezing nozzles. For example, of course, the cooling nozzle may be referred to as a first nozzle, and the freezing nozzle may be referred to as a second nozzle.

Figure 17(b) shows the first body 1111 of the cooling nozzle, and the first body 1111 of the cooling nozzle includes a 1-1 part (P1-1) and a 1-2 part (P1-2). ), and can be divided into 1-3 parts (P1-3).

Figure 17 (c) shows the second body 1112 of the freezing nozzle, and the second body 1112 of the freezing nozzle is divided into a 2-1 part (P2-1) and a 2-2 part (P2). -2), and can be divided into the 2-3 part (P2-3). Here, the cooling nozzle may refer to a nozzle designed to correspond to the above-described cooling mode, and the freezing nozzle may refer to a nozzle designed to correspond to the above-described freezing mode.

Referring to Figures 17 (b) and (c), the length of the first body 1111 of the cooling nozzle may be shorter than the length of the second body 1112 of the freezing nozzle.

The reason is that, as mentioned above, the temperature range of the object to be controlled in the cooling mode is relatively higher than the temperature range of the object to be controlled in the freezing mode, and the injection port 1121 of the nozzle 1100 through which the coolant is sprayed and the object are This is because the shorter the distance, the lower the temperature when the coolant reaches the target.

Another reason is that in the cooling mode, unlike the freezing mode, a temperature control method is performed. In the temperature control method, a sensor unit 1600 is used to measure the temperature of a specific area, and referring to FIG. 3, the nozzle 1100 If the length of , the nozzle 1100 covers part or all of the temperature measurement area of the sensor unit 1600, making accurate temperature measurement difficult. Therefore, in the case of the cooling nozzle, the length is limited depending on the temperature measurement area of the sensor unit 1600, while in the case of the freezing nozzle, there is no such limitation, so the length of the first body 1111 of the cooling nozzle is that of the freezing nozzle. It may be relatively short compared to the length of the second body 1112.

The difference in length between the cooling nozzle and the freezing nozzle may be due to the difference in length of the first part P1 of the nozzle 1100. For example, the 1-1 part (P1-1) of the first body 1111 may be shorter than the 2-1 part (P2-1) of the second body 1112. Here, the length of the 1-2 part (P1-2) of the first body 1111 and the length of the 2-2 part (P2-2) of the second body 1112 are formed by a sealing member ( 1130) may be substantially the same. Also, here, the length of the 1-3 part (P1-3) of the first body 1111 and the length of the 2-3 part (P2-3) of the second body 1112 are determined by the nozzle of the cooling device 1000. They may be substantially the same in that they must correspond to the shape of the coupling portion 1200.

Meanwhile, the length difference between the cooling nozzle and the freezing nozzle does not necessarily result from the length difference between the first part (P1) of the nozzle 1100, and the length difference between the cooling nozzle and the freezing nozzle is caused by the length difference between the second part of the nozzle 1100. This may be due to a difference in length between the portion P2 and/or the third portion P3.

Referring to Figures 17 (b) and (c), the 1-3 part (P1-3) of the cooling nozzle and the 2-3 part (P2-3) of the freezing nozzle may have different shapes. . Here, the first body 1111 of the cooling nozzle extends from the 1-1 stage (E1-1) to the 1-2 stage (E1-2) (or, the 1-1 stage (E1-1) and (with the 1-2 end (E1-2)) a 1-1 part (P1-1) along the direction from the 1-1 end (E1-1) to the 1-2 end (E1-2), It can be divided into -2 part (P1-2), and 1-3 part (P1-3). In addition, the second body 1112 of the freezing nozzle extends from the 2-1 stage (E2-1) to the 2-2 stage (E2-2) (or, the 2-1 stage (E2-1) and a 2-1 part (P2-1) along the direction from the 2-1 stage (E2-1) to the 2-2 stage (E2-2) with the 2-2 stage (E2-2), It can be divided into part 2-2 (P2-2), and part 2-3 (P2-3).

As an example, the 1-3 portion (P1-3) of the first body 1111 may include a groove (GR) formed in the 1-1 end (E1-1). On the other hand, the 2-3 portion (P2-3) of the second body 1112 may not include the groove (GR) formed in the 2-1 end (E2-1).

As another example, the width (or diameter) of the portion adjacent to the 1-1 end (E1-1) of the 1-3 portion (P1-3) of the first body 1111 is the 1-3 portion (P1-3). ) may be smaller than the width of the portion closer to the 1-2nd stage (E1-2) than the 1-1st stage (E1-1). On the other hand, the 2-3 portion (P2-3) of the second body 1112 may have a constant width (or diameter).

At this time, the width (or diameter) of the 1-3 part (P1-3) of the first body 1111 is the width (or diameter) of the 2-3 part (P2-3) of the second body 1112. It can be smaller than Specifically, the width (or diameter) of the portion adjacent to the 1-1 end (E1-1) of the 1-3 portion (P1-3) of the first body 1111 is the second portion of the second body 1112. It may be smaller than the width (or diameter) of the part adjacent to the 2-1st stage (E2-1) among the -3 parts (P2-3).

Meanwhile, the 1-3 part (P1-3) of the first body 1111 and the 2-3 part (P2-3) of the second body 1112 may be implemented in a shape opposite to that described above. For example, the groove GR may not be formed in the 1-3 part P1-3, but the groove GR may be formed in the 2-3 part P2-3. For another example, the width (or diameter) of the 1-3 portion (P1-3) is constant and the width (or diameter) of the 2-3 portion (P2-3) is the 2-1 end (E2-1). ) is smaller than the width (or diameter) of the part closer to the 2-2nd end (E2-2) than the 2-1st end (E2-1) of the 2-3rd part (P2-3). You can. For another example, the width (or diameter) of the portion adjacent to the 1-1 end (E1-1) of the 1-3 portion (P1-3) of the first body 1111 is the width (or diameter) of the second body 1112. It may be larger than the width (or diameter) of the portion adjacent to the 2-1 end (E2-1) of the 2-3 portion (P2-3) of .

Hereinafter, a method for determining a mode in the cooling device 1000 will be described with reference to FIG. 18.

In the cooling system 100, the control unit 1900 may control the cooling system 100 to operate in a cooling mode, freezing mode, or other modes. At this time, in order to determine the mode in which the cooling system 100 operates, the cooling system 100 may include a hardware configuration or may be equipped with a software algorithm.

As an example, the cooling system 100 may include a mode recognition unit. The mode recognition unit can transmit a signal to the control unit 1900 when a specific condition is satisfied, and the control unit 1900 can control the cooling device 1000 to operate in a specific mode or determine the mode based on the received signal.

As another example, the control unit 1900 of the cooling system 100 may output a screen or notification regarding mode selection through the output unit 1800. The control unit 1900 may receive input from the user and control the cooling device 1000 to operate in a specific mode or determine the mode.

Referring to FIG. 18, the control unit 1900 outputs the eighth screen through the status output unit 1840, and the eighth screen displays the 15th display area C15 to indicate that it is a mode selection screen and the mode to be selected. It may include a sixteenth display area C16 for: The eighth screen may be displayed on the status output unit 1840 when the user turns on the power button of the cooling device 1000. The user can select a mode using the manipulation module 1740.

Below, as another example, a method in which the mode is determined according to the type of the nozzle 1100, including the hardware configuration of the cooling device 1000, will be described as another example. However, the technical idea of the present specification is not limited to this. no.

FIG. 19 is a diagram showing whether the recognition sensor RS is detected in the process of coupling the nozzle 1100 to the main body MB according to an embodiment of the present specification. Specifically, Figure 18 (a) shows the nozzle 1100 being attached and detached to the main body (MB) of the cooling device 1000, and Figure 18 (b) shows the cooling nozzle 1101 being attached to the main body (MB). Figure 18(c) shows a case where the freezing nozzle 1102 is mounted on the main body MB.

Referring to FIG. 19, the main body (MB) of the cooling device 1000 may include a recognition sensor (RS). The recognition sensor RS can be understood as an example of the mode recognition unit described above.

The recognition sensor RS may or may not generate a recognition signal during the process of coupling the nozzle 1100 to the main body MB. Specifically, the recognition sensor RS may not generate a recognition signal when a cooling nozzle is coupled to the main body MB, but may generate a recognition signal when a freezing nozzle is coupled to the main body MB. The recognition sensor RS may be electrically connected to the control unit 1900, and the control unit 1900 may receive a recognition signal generated from the recognition sensor RS. The control unit 1900 may change the mode in which the cooling device 1000 operates based on the recognition signal received from the recognition sensor RS.

As an example of a recognition sensor (RS), a pressed switch that generates a signal when pressed may be proposed. In this case, the recognition sensor RS may generate a signal when the nozzle 1100 is pressed as it is coupled to the main body MB, and may not generate a signal when it is not pressed. Specifically, referring to FIG. 19, the recognition sensor (RS) is disposed around the nozzle coupling portion 1200, and when the cooling nozzle 1101 is coupled to the main body (MB), the recognition sensor (RS) is not pressed and the recognition signal is not transmitted. It may not be created. This means that a groove (GR) is formed in the first-third portion (P1-3) of the first body (1111) of the cooling nozzle (1101), and when the cooling nozzle (1101) is coupled to the body (MB), a recognition sensor This is because (RS) is located in the home (GR). On the other hand, when the freezing nozzle 1102 is coupled to the main body MB, the recognition sensor RS may be pressed by the second body 1112 of the freezing nozzle 1102 to generate a recognition signal. The control unit 1900 may control the cooling device 1000 to operate in the cooling mode and operate in the freezing mode upon receiving a recognition signal generated by the recognition sensor (RS). Alternatively, the control unit 1900 controls the cooling device 1000 to operate in a cooling mode when it does not receive a recognition signal generated by the recognition sensor (RS), and when it receives a recognition signal from the recognition sensor (RS), the cooling device 1000 ) can be controlled to operate in freezing mode.

Meanwhile, the mode decision of the cooling device 1000 according to the generation and reception of the recognition signal by the recognition sensor RS is not necessarily limited to the above-described pattern. For example, there are different types of first nozzles and second nozzles coupled to the cooling device 1000, and the cooling device 1000 has a first mode corresponding to the first nozzle or a mode corresponding to the second nozzle. When operating in 2 mode, the recognition sensor (RS) generates a recognition signal when the first nozzle is coupled to the nozzle coupling portion 1200 of the cooling device 1000, and the control unit 1900 generates a recognition signal by the recognition sensor RS. Upon receiving the generated recognition signal, the cooling device 1000 can be controlled to operate in the first mode. At this time, the first nozzle may be a cooling nozzle 1101 and the first mode may be a cooling mode, and the second nozzle may be a freezing nozzle 1102 and the second mode may be a freezing mode. Alternatively, as described above, the first nozzle may be the freezing nozzle 1102 and the first mode may be the freezing mode, and the second nozzle may be the cooling nozzle 1101 and the second mode may be the cooling mode.

As another example of a recognition sensor (RS), an ambient light sensor that measures surrounding brightness may be proposed. In this case, the recognition sensor RS generates a detection signal corresponding to the surrounding brightness, but the detection signal may vary depending on the shape of the nozzle 1100 coupled to the main body MB. The control unit 1900 may receive a detection signal from the recognition sensor RS and determine, maintain, or change the mode according to the received detection signal. At this time, the shape of the nozzle 1100 may have a shape that covers or does not cover the recognition sensor RS, and specifically, depending on the shape of the third part P3 of the body 1110, The generated detection signal value may vary.

Meanwhile, the cooling device 1000 may recognize the mode using near field communication (NFC). For example, the cooling device 1000 may include an NFC module, and the nozzle 1100 may also include an NFC communication unit that includes different information for each type. For example, the first nozzle for the cooling mode includes a first NFC communication unit, the second nozzle for the freezing mode includes a second NFC communication unit, and the third nozzle for the boosting mode includes a third NFC communication unit. It can be included. The cooling device 1000 can identify the type of nozzle 1100 to be coupled using the NFC module and determine the mode based on the type of the identified nozzle 1100.

Hereinafter, a method for strongly coupling the nozzle 1100 and the nozzle coupling portion 1200 will be described with reference to FIGS. 20 to 22.

Figure 20 is a diagram showing the nozzle coupling portion 1200 according to an embodiment of the present specification.

Referring to FIG. 20, the nozzle coupling portion 1200 may include a coupling portion 1210, a packing member receiving groove 1220, and a close contact portion 1230.

The coupling portion 1210 refers to a portion coupled to the nozzle 1100. For example, when the nozzle 1100 and the nozzle coupling portion 1200 are screwed together, a thread is formed on at least a portion of the coupling portion 1210 and at least a portion of the third portion P3 of the nozzle 1100. A thread corresponding to the coupling portion 1210 may be formed. For another example, when the nozzle 1100 and the nozzle coupling portion 1200 are tightly coupled, the coupling portion 1210 and the third portion P3 of the nozzle 1100 may have shapes that correspond to each other. .

The packing member receiving groove 1220 can accommodate a packing member described later. The packing member receiving groove 1220 may be formed in the coupling direction with respect to the coupling portion 1210. Here, the coupling direction may refer to the direction in which the nozzle 1100 is coupled to the nozzle coupling portion 1200. The packing member receiving groove 1220 is formed in the coupling direction based on the coupling portion 1210, so that when the nozzle 1100 is coupled to the nozzle coupling portion 1200, it begins to be coupled with the coupling portion 1210 first, and the nozzle ( When 1100) and the nozzle coupling portion 1200 are completely coupled, they can be tightened more tightly by a packing member to be described later.

The close contact portion 1230 may refer to a portion that is in close contact with a portion of the nozzle 1100 when the nozzle 1100 is coupled to the nozzle coupling portion 1200. For example, the close contact portion 1230 may be in close contact with the sealing member 1130 of the nozzle 1100. The close contact portion 1230 may have a first diameter (R1) and a first thickness (T1). The shape or size of the close contact portion 1230 may correspond to the shape and size of the receiving portion formed in the sealing member 1130, which will be described later.

The close contact portion 1230 may protrude from the coupling portion 1210 of the nozzle coupling portion 1200. The close contact portion 1230 may protrude from the coupling portion 1210 in a direction opposite to the coupling direction. A coupling portion 1210 may be located between the close contact portion 1230 and the packing member receiving groove 1220.

Figure 21 is a diagram showing the sealing member 1130 of the nozzle 1100 according to an embodiment of the present specification. Specifically, Figure 21 (a) shows the sealing member 1130, Figure 21 (b) shows a cross section of the sealing member 1130, and Figure 21 (c) shows the body 1110 on the back of the nozzle 1100. ) shows a state in which the sealing member 1130 is inserted. Among the contents regarding the sealing member 1130, the contents previously described in FIG. 16 are omitted as they are redundant.

Referring to (b) of FIG. 21, the sealing member 1130 may include a first groove 1131 and a second groove 1132.

The first groove 1131 may be formed so that the spray portion 1110 of the nozzle 1100 comes into close contact with it.

The second groove 1132 may be formed so that the contact portion 1230 of the above-described nozzle coupling portion 1200 comes into close contact.

The second groove 1132 may have a second diameter (R2) and a second thickness (T2). The size of the second groove 1132 may correspond to the size of the close contact portion 1230 of the nozzle coupling portion 1200. For example, the first diameter R1 of the close contact portion 1230 may be substantially equal to the second diameter R2 of the second groove 1132. Alternatively, the first diameter R1 of the close contact portion 1230 may be larger than the second diameter R2 of the second groove 1132. Additionally, the first thickness T1 of the close contact portion 1230 may be substantially equal to the second thickness T2 of the second groove 1132. Alternatively, the first thickness T1 of the close contact portion 1230 may be greater than the second thickness T2 of the second groove 1132. As described above, when the size of the close contact portion 1230 and the size of the second groove 1132 correspond to each other, leakage of coolant passing through the nozzle coupling portion 1200 and the nozzle 1100 can be prevented.

In the same context, the shape of the second groove 1132 may correspond to the shape of the close contact portion 1230 of the nozzle coupling portion 1200.

FIG. 22 is a diagram illustrating a process in which the nozzle 1100 is coupled while the packing member (PE) is coupled to the nozzle coupling portion 1200 according to an embodiment of the present specification.

Referring to (a) of FIG. 22, a packing member (PE) may be coupled to the nozzle coupling portion 1200. The packing member (PE) may be coupled to the packing member receiving groove 1220 of the nozzle coupling portion 1200.

The packing member (PE) may be an O-ring made of materials such as natural rubber, synthetic rubber, silicone, and synthetic resin.

After the packing member (PE) is coupled to the nozzle coupling portion 1200, the nozzle 1100 may be coupled. Referring to (b) of FIG. 22, in the process of coupling the nozzle 1100 to the nozzle coupling portion 1200, the nozzle coupling portion 1200 will be accommodated in the third portion (P3) of the body 1110 of the nozzle 1100. You can. At this time, the third part (P3) may include a first inner surface (IS1) corresponding to the coupling part 1210 of the nozzle coupling part 1200 and a second inner surface (IS2) corresponding to the packing member (PE). there is. The first inner surface (IS1) of the third part (P3) is joined by the coupling part 1210, and the second inner surface (IS2) is packed by the packing member (PE), and further, the nozzle coupling part ( Since the close contact portion 1230 of the 1200 is in close contact with the second groove 1132 of the sealing member 1130, leakage of the coolant when the coolant is sprayed from the cooling device 1000 can be completely blocked.
