Description

Technical Field

[0001] The present disclosure relates to a mixing module used in a refrigerant supply device. More specifically, the present disclosure relates to a module designed to mix a composition with a refrigerant and spray it, taking into account problems that may arise due to the characteristics of the composition.

Background Art

[0002] In the fields of cosmetics and medical devices, a method of spraying a composition containing an active ingredient to effectively deliver it to a target is a very important task, and research on such methods has been actively conducted to date.

[0003] Considering the temperature of the composition in effectively delivering the composition to the target, in particular, research on techniques for cooling and delivering the composition to improve its penetration performance is quite limited.

[0004] On the other hand, as a method of lowering the temperature of the composition, there may also be a method of spraying the composition together with a refrigerant. In this regard, stable control of the temperature of the composition, uniformity of spraying of the composition, and stability of spraying of the composition may be affected depending on the structure of the module in which the composition and the refrigerant are mixed. Specifically, when the composition used has physical properties such as high viscosity, strong adhesion, or low freezing point, the importance of module structure design increases.

[0005] The present disclosure introduces the structure of the module to efficiently mix the refrigerant and the composition, and proposes a desirable design direction when considering the characteristics of the composition.

[0138] For example, in this specification, when it is mentioned that a film, region, component, etc. is electrically connected to another film, region, component, etc., the film, the region, the component, etc. can be directly electrically connected to the other film, region, component, etc., and the connection can be achieved electrically indirectly using other films, regions, components, etc. intervening between them.

[0139] In the embodiments described below, when it is mentioned that a film, region, component, etc. is fluidly connected to another film, region, component, etc., it can be understood that the film, the region, the component, etc. can form at least a part of a flow path through which each liquid flows.

[0140] For example, in this specification, when component A is fluidly connected to component B, it may mean that the liquid passing through the flow path formed by component A can reach the flow path formed by component B or vice versa. Specifically, when component A and component B are coupled to each other and the flow path formed by component A and the flow path formed by component B are directly connected to each other, component A and component B can be regarded as being fluidly connected to each other. Alternatively, when component A and component B are connected to each other through component C such as a conduit, whereby the flow path formed by component A and the flow path formed by component B are indirectly connected to each other through the flow path formed by component C, component A and component B can be regarded as being fluidly connected to each other. In this regard, component C can be understood as fluidly connecting components A and B to each other. Further, component A and component B may be fluidly connected to each other through a plurality of components.

[0141] This specification relates to a mixing module used in a refrigerant supply device. The mixing module is intended to mix a composition with the refrigerant supplied from the refrigerant supply device and spray the refrigerant and the composition together. Since the refrigerant and the composition are mixed together and their mixture is sprayed onto the target, a relatively low-temperature composition can be sprayed onto the target.

[0142] In this regard, the composition has a concept that includes not only pharmaceutical compositions used for medical treatment purposes but also cosmetic compositions used for cosmetic purposes, and the composition may mean a material having an active ingredient that induces or produces a medical effect or a cosmetic effect.

[0143] In this regard, as the refrigerant, materials such as carbon dioxide (CO2), liquid nitrogen (LN), nitrogen dioxide (NO2), nitric oxide (NO), materials of the hydrofluorocarbon (HFC) family, methane (CH4), PFC, SF6, coolant, cooling gas, etc., that can add cooling energy to the target area can be used.

[0144] In this regard, "target" can mean the body part on which a procedure, treatment, or care is performed to produce a cosmetic or medical effect. For example, the target can mean the skin of the body. Hereinafter, for convenience of explanation, this specification mainly describes the case where the target is the skin of the body, but the scope and spirit of this specification are not limited thereto.

[0145] The degree of penetration of the composition into the skin of the body can be affected by the skin temperature. Specifically, when the skin temperature drops to a predetermined level, the skin cells contract, the gaps between the skin cells increase, and the composition penetrates through the gaps between the skin cells, and as a result, the penetration of the composition can be improved.

[0146] On the other hand, when the refrigerant and the composition are mixed and sprayed, various problems can occur. For example, aggregation of the composition can cause problems such as the composition not being sprayed uniformly, the composition not being uniformly dispersed in the spray area of the refrigerant, and the composition freezing due to the refrigerant.

[0147] In this regard, the problem that the composition is not sprayed uniformly due to aggregation of the composition or the problem that the composition is not uniformly dispersed in the spray area of the refrigerant can result in deterioration of penetration.

[0148] Specifically, in order to effectively penetrate the composition, the composition needs to be sprayed with a sufficiently strong force (or pressure). If the size (or its mass) of the composition increases while the composition collides with the sprayed refrigerant (or receives the kinetic energy of the sprayed refrigerant), according to the law of conservation of momentum, the spraying speed of the composition can decrease. In other words, the total amount of energy possessed by the sprayed refrigerant is divided and shared with the composition, and in this regard, by dividing the composition into more uniform particle sizes, the composition can be sprayed with a stronger force (or at a higher speed), and thus, the penetration force can be improved.

[0149] Furthermore, the problem of the composition freezing due to the refrigerant may cause the mixture spray system or the mixing module to stop operating, or may act to cause inconvenience to the person being treated.

[0150] In this specification, a mixing module that improves permeability and convenience by removing the above-described problems will be described.

[0151] 1. Mixture spray system First, before describing the mixing module, the mixture spray system and the manner of using the mixing module in the mixture spray system will be first described with reference to FIGS. 1 and 2.

[0152] FIG. 1 is a diagram showing a mixture spray system 100 according to an embodiment.

[0153] Referring to FIG. 1, the mixture spray system 100 may include a mixing module 1000 and a refrigerant supply device 2000.

[0154] First, the refrigerant supply device 2000 may mean a device that supplies refrigerant. Specifically, the refrigerant supply device 2000 may supply refrigerant to the mixing module 1000. The refrigerant supply device 2000 may be called by various names such as a refrigerant spray device, a spray device, etc.

[0155] The refrigerant supply device 2000 may be configured to store refrigerant therein, or to be supplied with refrigerant from a separate refrigerant storage means. For example, as described below, the refrigerant supply device 2000 is coupled to a cartridge that stores refrigerant therein and may obtain refrigerant from the cartridge coupled to itself. As another example, the refrigerant supply device 2000 may be supplied with refrigerant from an external refrigerant reservoir through a hose.

[0156] The refrigerant supply device 2000 can determine the characteristics of the supplied refrigerant. For example, the refrigerant supply device 2000 can control the supply amount, supply time, temperature, and / or pressure of the refrigerant, etc.

[0157] The mixing module 1000 can be supplied with refrigerant from the refrigerant supply device 2000.

[0158] The mixing module 1000 can store the composition inside. For example, the mixing module 1000 may include a container for storing the composition inside as described below. Otherwise, the mixing module 1000 can be supplied with the composition from the outside.

[0159] The mixing module 1000 can provide a mixing space where the refrigerant and the composition are mixed together. A method for mixing the refrigerant and the composition will be described below.

[0160] FIG. 2 is a diagram showing the process in which the components of the mixture spray system 100 are coupled to each other according to one embodiment.

[0161] The mixing module 1000 can be removed or attached to the refrigerant supply device 2000. Specifically, the mixing module 1000 can be mounted or separated from one component of the refrigerant supply device 2000.

[0162] Referring to FIG. 2, the refrigerant supply device 2000 may include a main body MB, a refrigerant spray unit 2100 coupled to the main body MB, and a cartridge CTR, and the mixing module 1000 may be coupled to the refrigerant spray unit 2100.

[0163] Also, the mixture spray system 100 may further include a cover COV that covers the refrigerant spray unit 2100. The cover COV may be coupled to the main body MB of the refrigerant supply device 2000.

[0164] Referring to FIG. 2, the refrigerant spray unit 2100 and the cover COV may be sequentially coupled to the main body MB, in which case the mixing module 1000 may be coupled to the refrigerant spray unit 2100. The cover COV may form a space for the refrigerant spray unit 2100 to pass through. Thus, when the cover COV is coupled to the main body MB, the refrigerant spray unit 2100 may penetrate the cover COV.

[0165] In the mixture spray system 100, the cover COV may be omitted. Alternatively, in the mixture spray system 100, the cover COV may be realized as part of the mixing module 1000. Alternatively, in the mixture spray system 100, the cover COV may be realized as part of the refrigerant supply device 2000.

[0166] As described above, the mixture spray system 100 is divided into a plurality of components, and the case where the divided components are coupled and separated from each other has been described. As described above, since the mixing module 1000 is separable from the refrigerant supply device 2000, the mixing module 1000 can be used disposable. Alternatively, the mixing module 1000 that has been used once or more may be cleaned and reused.

[0167] On the other hand, the refrigerant spray unit 2100 and the mixing module 1000 of the mixture spray system 100 may be realized as an integrated body in which the refrigerant spray unit 2100 and the mixing module 1000 are physically connected to each other. Also, the mixing module 1000 and the refrigerant supply device 2000 in the mixture spray system 100 may be realized as an integrated body in which the mixing module 1000 and the refrigerant supply device 2000 are physically connected to each other. For example, the refrigerant spray unit 2100 may be provided as part of the mixing module 1000. As another example, the refrigerant spray unit 2100 and the mixing module 1000 may be provided as part of the refrigerant supply device 2000.

[0168] 2. Refrigerant Supply Device Hereinafter, the refrigerant supply device 2000 will be described with reference to FIG. 3.

[0169] FIG. 3 is a diagram showing the components of the refrigerant supply device 2000 according to one embodiment.

[0170] Referring to FIG. 3, the refrigerant supply device 2000 may include a refrigerant spray unit 2100, a spray unit coupling unit 2200, a temperature adjustment unit 2300, a flow rate adjustment unit 2400, a cartridge coupling unit 2500, a sensor unit 2600, an input unit 2700, an output unit 2800, and a control unit 2900.

[0171] The refrigerant spray unit 2100 may have a structure for spraying refrigerant. Specifically, the refrigerant spray unit 2100 may form a flow path extending from one end to the other end, and may include a portion having a relatively narrow width of the flow path. The liquid passing through the refrigerant spray unit 2100 expands with a decrease in pressure as it passes through the narrow portion of the flow path, and as a result, the liquid can be sprayed at high speed. In this regard, adiabatic expansion of the liquid is achieved while the liquid passes through the refrigerant spray unit 2100, whereby the liquid becomes cold and can be controlled to a temperature suitable for the procedure or treatment by the temperature adjustment unit 2300 described below for the temperature of the refrigerant.

[0172] The refrigerant spray unit 2100 may be understood as a nozzle. However, the technical concept of this specification is not limited thereto, and the refrigerant spray unit 2100 may be understood as a component having a flow path with an arbitrary tube shape.

[0173] The refrigerant spray unit 2100 can be attached to and detached from the main body MB of the refrigerant supply device 2000. For example, the refrigerant spray unit 2100 can be coupled to or separated from the main body MB via a spray unit coupling unit 2200. Alternatively, the refrigerant spray unit 2100 may be physically connected to the main body MB so as to be integrally formed with the main body MB of the refrigerant supply device 2000.

[0174] As described above, the mixing module 1000 may be coupled to the refrigerant spray unit 2100. For this purpose, the refrigerant spray unit 2100 and the mixing module 1000 may each include a coupling portion or a coupling member.

[0175] On the other hand, the mixing module 1000 may be designed in various shapes as described below. Specifically, the structure of the mixing module 1000 may vary depending on the type of composition to be used. As a result, depending on the type of the mixing module 1000 coupled to the refrigerant spray unit 2100, the functions or effects that will occur when using the mixture spray system 100 may be different.

[0176] The spray unit coupling unit 2200 may be coupled to the refrigerant spray unit 2100. On the other hand, when the refrigerant spray unit 2100 is omitted from the mixture spray system 100 or when the refrigerant spray unit 2100 becomes a part of the mixing module 1000, the mixing module 1000 may be coupled to the spray unit coupling unit 2200.

[0177] A flow path through which the refrigerant moves may be formed in the spray unit coupling unit 2200. For example, the spray unit coupling unit 2200 may have an outlet hole, and the refrigerant may move through the outlet hole to the refrigerant spray unit 2100 coupled to the spray unit coupling unit 2200.

[0178] The temperature adjustment unit 2300 may adjust the temperature of the refrigerant. For example, the temperature adjustment unit 2300 may supply thermal energy to the refrigerant, whereby the temperature of the refrigerant may rise, and the temperature of the refrigerant may be adjusted according to the amount of thermal energy supplied from the temperature adjustment unit 2300. The refrigerant sprayed through the refrigerant spray unit 2100 may be relatively low in temperature as described above, and in this regard, the temperature of the refrigerant may vary according to the thermal energy supplied from the temperature adjustment unit 2300.

[0179] The temperature adjustment unit 2300 may include a heat generator that generates thermal energy and a heat transfer device that transfers the generated thermal energy to the flow path through which the refrigerant moves. For example, the heat generator may include an element that utilizes a thermoelectric effect such as the Peltier effect, and may generate thermal energy according to the applied electricity and the heat generator.

[0180] The flow rate adjustment unit 2400 may control the movement of the refrigerant. For example, the flow rate adjustment unit 2400 may have a valve and may open and close the valve by receiving a signal from the control unit 2900. Depending on whether the valve is open or closed, the refrigerant may or may not be moved. The fluidity of the refrigerant may be controlled according to the opening and closing degree of the valve.

[0181] The cartridge coupling unit 2500 may accommodate at least a part of the above-described cartridge CTR. In this regard, the cartridge CTR may be understood as a container that stores the refrigerant inside. Specifically, the cartridge CTR may store the refrigerant inside under a predetermined pressure, and the predetermined pressure may be determined to be between approximately 35 bar (3.5 MPa) and 100 bar (10 MPa) based on 0 to 40°C. The pressure in the cartridge CTR may affect the spray amount or spray shape of the refrigerant and may indirectly affect the spray amount of the composition.

[0182] While the cartridge CTR is coupled to the cartridge coupling unit 2500, the refrigerant stored in the cartridge CTR may move to the main body MB.

[0183] The sensor unit 2600 can measure the temperature of the portion where the refrigerant is sprayed. For example, the sensor unit 2600 can measure the temperature of the skin surface where the refrigerant is sprayed and provide the measurement information to the control unit 2900.

[0184] The input unit 2700 can receive user input. For example, the input unit 2700 may include at least one push button switch, and a push input signal may be provided to the control unit 2900 according to the pressure applied to this switch by the user. The control unit 2900 may control the opening and closing of the flow rate adjustment unit 2400 based on this push input signal. Further, the input unit 2700 may include at least one rotary switch, and a rotary input signal may be provided to the control unit 2900 according to the user's operation. The control unit 2900 may preset the target cooling temperature or the target cooling time based on the rotary input signal. In this regard, the target cooling temperature may mean the temperature at the target that the user desires to cool. Here, the target is the part (for example, the skin surface) where the refrigerant will be sprayed. Further, the target cooling time may mean the time for which the spraying of the refrigerant should be maintained or the time for which the temperature of the skin surface should be kept at the target cooling temperature.

[0185] The output unit 2800 can output an interface and various information for the user to use the refrigerant supply device 2000. For example, the output unit 2800 may include a display, and through this display, an interface for setting the target cooling temperature, the target cooling time, etc. may be output. During the operation of the refrigerant supply device 2000, the output unit 2800 may output the real-time temperature of the skin surface measured by the sensor unit 2600 or the total time for which the refrigerant is sprayed.

[0186] The control unit 2900 may control the components of the refrigerant supply device 2000. For example, the control unit 2900 may control the temperature adjustment unit 2300 to control the temperature of the refrigerant, may control the flow rate adjustment unit 2400 to control the flow rate of the refrigerant, and may output specific information for the user through the output unit 2800.

[0187] Referring to FIG. 3, the refrigerant supply device 2000 may operate as follows.

[0188] The control unit 2900 may first preset a target cooling temperature and / or a target cooling time. The control unit 2900 may provide an interface through the output unit 2800 to guide the user to preset the target cooling temperature and / or the target cooling time, and the control unit 2900 may receive a setting input signal corresponding to the user's operation through the input unit 2700, and may preset the target cooling temperature and / or the target cooling time based on the received setting input signal.

[0189] Next, the control unit 2900 may output a message indicating that the operation preparation is completed to the user through the output unit 2800, and the control unit 2900 may receive a switch-on input signal corresponding to the user's operation through the input unit 2700, and may spray the refrigerant based on the received switch-on input signal.

[0190] While spraying the refrigerant, the control unit 2900 may obtain, from the sensor unit 2600, a temperature value of the target on which the refrigerant is sprayed, and may control the temperature adjustment unit 2300 by comparing the obtained temperature value with a preset target cooling temperature. In this regard, when the obtained temperature value is lower than the target cooling temperature, the control unit 2900 may increase the thermal energy applied to the refrigerant by the temperature adjustment unit 2300, and when the obtained temperature value is higher than the target cooling temperature, the control unit 2900 may decrease the thermal energy applied to the refrigerant by the temperature adjustment unit 2300.

[0191] The refrigerant supply device 2000 is not limited to the above-described embodiments, and any device and structure that perform the function of supplying refrigerant may be understood as the refrigerant supply device 2000 described in this specification.

[0192] As an example, the refrigerant supply device 2000 may control the temperature of the refrigerant in such a way that a predetermined amount of thermal energy is continuously supplied to the refrigerant without monitoring the temperature of the target. In this case, the step of presetting or receiving the target cooling temperature may be omitted.

[0193] 3. Mixing Module Hereinafter, the mixing module 1000 will be outlined with reference to FIGS. 4 to 6.

[0194] FIG. 4 is a diagram showing the mixing principle of refrigerant and composition according to one embodiment.

[0195] First, as shown in FIG. 4(a), the tubular mixing space can be regarded as including a refrigerant spray unit 2100 for spraying the refrigerant and an inlet hole IH for introducing the composition.

[0196] A container for storing the composition therein and an inlet hole IH may be fluidly connected to each other through a composition flow path. The composition flow path may be formed in a direction perpendicular to the central axis CA of the refrigerant spray unit 2100, but is not limited thereto.

[0197] Referring to FIG. 4(b), when the refrigerant is sprayed from the refrigerant spray unit 2100, the spray shape of the refrigerant may be divided into a main flow MS and a sub-flow SS based on the central axis of the refrigerant spray unit 2100.

[0198] The main flow MS may mean a region where the refrigerant is sprayed relatively strongly, and the sub-flow SS may mean a region where the refrigerant is sprayed relatively weakly.

[0199] Furthermore, the main flow MS may be formed within a predetermined distance based on the central axis CA of the refrigerant spray unit 2100, and the sub-flow SS may be formed outside the predetermined distance based on the central axis CA of the refrigerant spray unit 2100. However, the criteria for dividing the main flow MS and the sub-flow SS are not limited to the criteria described above.

[0200] As described below, due to the negative pressure generated during the spraying of the refrigerant, the composition may be introduced into the main flow MS or the sub-flow SS of the refrigerant and mixed well with the refrigerant, and the mixed refrigerant and composition may be sprayed together. However, the forces applied to the composition by the refrigerant in the main flow MS and the sub-flow SS may be different.

[0201] The refrigerant sprayed from the refrigerant spray unit 2100 may pass near the inlet hole IH. When the refrigerant passes near the inlet hole IH at a relatively high speed, a negative pressure may be generated near the inlet hole IH according to Bernoulli's equation. The composition may be introduced into the mixing space through the inlet hole by the negative pressure formed near the inlet hole IH and mixed with the refrigerant. Specifically, it can be understood that an external force equal to the atmospheric pressure may be continuously applied to the container in which the composition is stored, and the composition moves as the external force becomes larger than the negative pressure.

[0202] The composition introduced into the inlet hole IH may collide with the refrigerant during the process of mixing the composition and the refrigerant, and thus, the composition may be divided into fine particles and sprayed.

[0203] FIG. 5 is a diagram showing a mixing module 1000 according to one embodiment.

[0204] FIG. 6 is a cross-sectional view showing a state in which a mixing module 1000 is coupled to a refrigerant spray unit 2100 according to one embodiment.

[0205] Referring to FIGS. 5 and 6, the mixing module 1000 may include a mixing unit 1100, a composition inlet unit 1200, a composition storage unit 1300, a cap 1400, and a fixing unit 1500.

[0206] The mixing unit 1100 may provide a mixing space 1110 in which the refrigerant and the composition are mixed together. Specifically, the inner surface of the mixing unit 1100 may define the mixing space 1110, and the inlet hole IH and the insertion hole SH may be formed on the inner surface of the mixing unit 1100. On the other hand, when the refrigerant spray unit 2100 is provided as a part of the mixing module 1000 or can be omitted, the insertion hole SH may be omitted.

[0207] The mixing unit 1100 may have a mixture spray hole 1120. The mixture spray hole 1120 may be understood as a boundary portion where the refrigerant and the composition are sprayed out of the mixing module 1000.

[0208] The composition inlet unit 1200 may mean a portion into which the composition is introduced. Specifically, the composition inlet unit 1200 may function to fluidly connect the composition storage unit 1300 that stores the composition therein and the mixing space of the mixing unit 1100. For this purpose, the composition inlet unit 1200 may form a pipe 1210 for moving the composition and the above-described inlet hole IH.

[0209] The pipe 1210 may provide a flow path through which the composition moves. The pipe 1210 may fluidly connect the composition storage unit 1300 and the mixing unit 1100.

[0210] The tube 1210 may have various shapes. For example, referring to FIG. 6, the tube 1210 may be realized in a shape including a bent portion. More specifically, the tube 1210 may have a shape bent in the distal direction. In this regard, the distal direction may be understood as the direction in which the refrigerant is sprayed or the direction from the first end 1100a to the second end 1100b of the mixing section 1100. Alternatively, one end of the tube 1210 located in the composition storage section 1300 may be located in a portion separated in the above-described distal direction based on the central axis of the composition storage section 1300. The above shape of the tube 1210 brings about the effect that as much as possible of the composition stored in the composition storage section 1300 is used when considering the usage mode of the mixture spray system 100. For example, when the mixture spray system 100 shown in FIG. 2 is used to spray the refrigerant and the composition, the spray direction is usually from the upper side (the direction opposite to gravity) to the lower side (the direction of gravity). In this case, the composition in the composition storage section 1300 can be moved in the distal direction (or forward) due to gravity. Therefore, in order to use as much as possible of the composition in the composition storage section 1300, one end of the tube 1210 needs to be located at the position where the composition moves thereto, that is, in the forward space based on the central axis of the composition storage section 1300.

[0211] The inlet hole IH may be formed on the inner surface of the mixing section 1100. The inlet hole IH may have a cross section parallel to the central axis of the mixing section 1100 on the inner surface of the mixing section 1100.

[0212] The tube 1210 and the inlet hole IH may be understood as an integral body. For example, a part of the tube 1210 may be understood as the inlet hole IH. For example, one end of the tube 1210 may be understood as the inlet hole IH.

[0213] Alternatively, the tube 1210 and the inlet hole IH may be provided as separate components, and the tube 1210 may be realized in a shape coupled to the inlet hole IH.

[0214] On the one hand, the direction in which the composition flows into the mixing section 1100 can be determined according to the position of the inlet hole IH. For example, as shown in FIG. 6, when the inlet hole IH is located at the lower part inside the mixing section 1100, the inflow direction of the composition may be closer to the direction opposite to the direction of gravity than to the direction of gravity. As another example, when the inlet hole IH is located at the upper part inside the mixing section 1100, the inflow direction of the composition may be closer to the direction of gravity than to the direction opposite to the direction of gravity. Hereinafter, the case where the inlet hole IH is located at the lower part inside the mixing section 1100 will be described, but the technical concept of the present disclosure is not limited thereto. Even when the inlet hole IH is located at the upper part inside the mixing section 1100, the following description can be similarly applied.

[0215] The composition storage section 1300 can provide a space for receiving the composition. The composition storage section 1300 can provide a space for storing the composition supplied from the external space.

[0216] The composition stored in the composition storage section 1300 may move to the mixing section 1100 through the composition inflow section 1200.

[0217] On the one hand, the composition may be continuously supplied to the mixture spray system 100 from the external space, and the composition storage section 1300 can be understood as a component that provides a space for the continuously supplied composition to stay before being introduced into the mixing section 1100.

[0218] The cap 1400 may be a component that seals the composition storage section 1300. In this regard, the composition may be stored in the composition storage section 1300 in the following manner. The user can open the cap 1400 coupled to the composition storage section 1300, move the composition contained in a separate composition container (for example, an ampoule, a cosmetic container, etc.) into the composition storage section 1300, and then close the cap 1400.

[0219] The fixing part 1500 may be fixed to the refrigerant spray unit 2100. The fixing part 1500 may have a support part 1510 and an insertion hole SH. The refrigerant spray unit 2100 may be inserted into the insertion hole SH. The support part 1510 may support the refrigerant spray unit 2100 inserted into the insertion hole SH. The fixing part 1500 and the refrigerant spray unit 2100 may each include members to be fixed to each other. The process in which the fixing part 1500 and the refrigerant spray unit 2100 are fixed to each other will be described below.

[0220] Referring to FIG. 5, the mixing module 1000 may include an outside air passage AP and a handle.

[0221] The outside air passage AP may be fluidly connected to the composition storage part 1300. The outside air passage AP may be capable of maintaining the pressure in the composition storage part 1300 at atmospheric pressure. Thus, when a negative pressure is generated in the inlet hole IH, the pressure in the composition storage part 1300 increases further, whereby the composition may move through the composition inlet part 1200 to the mixing part 1100.

[0222] The handle may be a component that can easily separate the mixing module 1000 from the refrigerant providing device 2000.

[0223] The above-described components of the mixing module 1000 may be manufactured independently and assembled with each other.

[0224] Alternatively, at least a part of the above-described components of the mixing module 1000 may be integrally formed. For example, the mixing part 1100, the composition storage part 1300, and the fixing part 1500 may be manufactured as an integrated body physically connected to each other, and the separately manufacturable pipe 1210 and the cap 1400 may be assembled thereto. As another example, the mixing part 1100, the composition storage part 1300, and the pipe 1210 may be manufactured as an integrated body physically connected to each other, and the cap 1400 may be manufactured as a separate object and assembled thereto.

[0225] On the other hand, the mixing module 1000 may be implemented differently from the above description. For example, the mixing module 1000 may include the above-described components and may have a container mounting portion instead of the composition storage portion 1300. The container mounting portion is configured such that the composition container is coupled thereto and may have a structure including a needle that can penetrate a stopper of the composition container or other structure to which the composition container can be coupled. The container mounting portion may be fluidly connected to the pipe 1210 or the inlet hole IH.

[0226] In this case, instead of pushing the composition into the composition storage portion 1300 of the mixing module 1000, the user can use the mixture spray system 100 in a form in which the composition container itself is coupled to the mixing module 1000.

[0227] Hereinafter, for convenience of explanation, this specification mainly describes the case where the mixing module 1000 includes the mixing portion 1100, the composition inflow portion 1200, the composition storage portion 1300, the cap 1400, and the fixing portion 1500, and the composition is transferred from a separate composition container to the composition storage portion 1300. However, the technical concept of this specification is not limited thereto.

[0228] On the other hand, when the above-described mixing module 1000 is used, various problems may occur depending on the characteristics of the composition (e.g., viscosity, cohesion, freezing point, adhesion, etc.). Hereinafter, various problems that may occur in the mixing module 1000 and solutions (e.g., directions for designing the mixing module 1000) will be described in detail.

[0229] 4. Mixing Module Design Hereinafter, with reference to FIG. 7, basic considerations and possible problems in the design of the mixing module 1000 will be described.

[0230] FIG. 7 is a diagram showing a mode of spraying a refrigerant into the mixing module 1000 according to one embodiment.

[0231] The mixing module 1000 is intended to move the composition by using a refrigerant spray without using a separate pressure device. For this purpose, the mixing module utilizes the negative pressure according to the Bernoulli formula described above.

[0232] Referring to FIG. 7, when the refrigerant is sprayed, a spray flow of the refrigerant can be generated in the mixing section 1100 of the mixing module 1000. In order to move the composition from the composition storage section 1300 to the mixing space 1110, a negative pressure should be generated at the inlet hole IH.

[0233] In order to generate a negative pressure at the inlet hole IH, the spray flow can pass near the inlet hole IH. In this regard, whether the spray flow passes near the inlet hole IH or not is determined according to the size of the spray flow, the width of the mixing section 1100, and the distance between the refrigerant spray hole 2110 and the inlet hole IH.

[0234] First, the size of the spray flow may mean the cross-sectional size of the spray flow. Specifically, it may mean the size of a cross-section perpendicular to the central axis CA of the refrigerant spray unit 2100 in the secondary flow SS. The cross-sectional size of the spray flow can increase as it moves away from the refrigerant spray hole 2110. Further, the cross-sectional size of the spray flow can increase as the spray angle at the refrigerant spray hole 2110 increases.

[0235] When the cross-sectional size of the spray flow corresponds to the width of the mixing section 1100, a part of the spray flow can be understood to approach or contact the inner surface of the mixing section 1100. In other words, based on the direction in which the refrigerant is sprayed, from a critical position at a predetermined distance from the refrigerant spray hole 2110, the spray flow may be close to or in contact with the inner surface of the mixing section 1100.

[0236] In order to generate a negative pressure by the spray flow in the inlet hole IH formed on the inner surface of the mixing part 1100, the position of the inlet hole IH should be determined based on the critical position described above. For example, the inlet hole IH may be formed at the critical position. As another example, the inlet hole IH may be formed within a predetermined distance in the distal direction (the spray direction of the refrigerant) based on the critical position. As another example, the inlet hole IH may be formed within a predetermined distance in the proximal direction (the direction opposite to the spray direction of the refrigerant) based on the critical position.

[0237] On the other hand, the size of the spray flow is relatively small near the refrigerant spray hole 2110 compared to the width of the mixing part 1100, so that the spray flow may not be generated on the inner surface of the mixing part 1100. Therefore, the inlet hole IH needs to be formed so as to be separated from the refrigerant spray hole 2110 by a predetermined distance in the distal direction (the spray direction of the refrigerant).

[0238] 4.1. Possible Problem #1 and Solution Plan On the other hand, as described above, the spray flow can be divided into the main flow MS and the secondary flow SS, and the spray speed of the refrigerant can be different between the main flow MS and the secondary flow SS. Specifically, the moving speed of the refrigerant in the main flow MS may be higher than the moving speed of the refrigerant in the secondary flow SS.

[0239] Due to the difference in the moving speed of the refrigerant for each region, a pressure difference may exist between the partial regions inside the mixing part 1100. For example, referring to FIG. 7, a relatively low air pressure may be generated around the refrigerant spray hole 2110 where the refrigerant moves at a relatively high speed in the mixing part 1100.

[0240] More specifically, when the refrigerant is sprayed, according to Bernoulli's equation, a first air pressure may be generated at the first low-pressure point P1 near the inlet hole IH, and a second air pressure may be generated at the second low-pressure point P2 near the refrigerant spray hole 2110.

[0241] In this regard, since the moving speed of the refrigerant near the inlet hole IH is faster than the moving speed of the refrigerant at the refrigerant spray hole 2110, the second air pressure at the second low pressure point P2 may be lower than the first air pressure at the first low pressure point P1. In other words, the composition introduced through the inlet hole IH can be forced to move to the second low pressure point P2 where a second air pressure lower than the first air pressure is generated.

[0242] On the other hand, the force of the spray flow applied to the composition introduced through the inlet hole IH can vary depending on the region. For example, the force of the refrigerant applied to the composition in the secondary flow SS may be smaller than the force of the refrigerant applied to the composition in the main flow MS. Also, as a force affecting the movement of the composition in the secondary flow SS, the external force generated by the difference between the first air pressure and the second air pressure may be larger than the force by the refrigerant.

[0243] Therefore, for this reason, in order to spray the composition introduced into the mixing section 1100 together with the refrigerant, it is preferable for the composition to move to the main flow MS of the refrigerant. Furthermore, the composition that does not move to the main flow MS may not be sprayed by the secondary flow SS, but may move in a direction opposite to the spray direction of the refrigerant due to the air pressure difference, or may move to the second air pressure point P2.

[0244] The composition that has moved near the second air pressure point P2 or the refrigerant spray hole 2110 may aggregate with each other depending on their properties. The aggregated composition can be sprayed by the refrigerant in a relatively large volume, and thus, compositions having different particle sizes can be sprayed from the mixing module 1000. As a result of spraying this non-uniform composition, problems such as the penetration effect of the composition on the target and the discomfort felt by the recipient (or the subject to be treated) are brought about.

[0245] To solve the above-described problems, a structure or device is required to induce the composition to reach the main flow MS. Alternatively, a structure or device can be used to prevent the composition from moving to the second low pressure point P2.

[0246] Hereinafter, the structure of the mixing module 1000 for solving the above-described problems will be described with reference to FIGS. 8 and 9.

[0247] FIG. 8 is a diagram showing a mixing module 1000 including a blocking member BM according to one embodiment.

[0248] Referring to FIG. 8, the blocking member BM may be formed on the inner surface of the mixing portion 1100 of the mixing module 1000. The blocking member BM may prevent the composition from moving to the refrigerant spray hole 2110 or the second end portion 1100b of the mixing portion 1100.

[0249] The blocking member BM may have a blocking surface BS.

[0250] The blocking surface BS may be in contact with a part of the composition inlet portion 1200. For example, the blocking surface BS may be in contact with or extend from the inlet hole IH.

[0251] The composition introduced through the inlet hole IH may move on the blocking surface BS of the blocking member BM and reach the main flow MS of the refrigerant. Therefore, the composition may not move to the second low-pressure point P2 near the refrigerant spray hole 2110.

[0252] The blocking surface BS may have a preset blocking angle with respect to the inlet hole IH. For example, the blocking surface BS may have a first angle preset with respect to a virtual plane including the cross section of the inlet hole IH. In this regard, the preset blocking angle may be determined between 0° and 90°. The blocking surface BS may be a plane, a curved surface, or a combination thereof.

[0253] The blocking member BM may have a preset blocking height BH. The blocking height BH may mean the height of the blocking member BM in a direction perpendicular to the central axis of the mixing portion 1100 based on the inlet hole IH.

[0254] The cutoff height BM may be preset as the height of the main flow MS of the refrigerant. For example, when the width of the main flow MS is half of the width of the mixing section 1100, the cutoff height may be determined to be less than half of the width of the mixing section 1100.

[0255] The cutoff member BM may be integrally formed with the mixing section 1100. Specifically, the cutoff member BM may be shaped to protrude from the inner surface of the mixing section 1100.

[0256] The cutoff member BM may be formed separately from the mixing section 1100 and coupled to the inner surface of the mixing section 1100.

[0257] On the other hand, when the cutoff member BM is used to block the aggregation of the composition, the composition used for mixing and spraying needs to have a relatively low adhesion force. In this regard, the adhesion force can be understood as the attracting force between the cutoff member BM and the composition. Therefore, when a composition having a high adhesion force is used, the composition may climb up the cutoff surface BS of the cutoff member BM, and as a result, an action may occur in which the composition aggregates at the second low-pressure point P2.

[0258] Furthermore, when the cutoff member BM is used, the composition used for mixing and spraying needs to have a relatively high freezing point. This is because the temperature of the cutoff member BM can be decreased by the sprayed refrigerant, and thus the temperature of the composition moving on the cutoff member BM also decreases, resulting in the problem that the composition is sprayed in a frozen state.

[0259] FIG. 9 is a diagram showing a mixing module 1000 including an inclined member IM according to one embodiment.

[0260] The region where the composition aggregates in the mixing section 1100 of the mixing module 1000 may be filled. Referring to FIG. 9, the mixing module 1000 may include an inclined member IM.

[0261] The inclined member IM may be understood as a block, slope path, or ramp having an inclination. The inclined member IM may be disposed between the inlet hole IH and the refrigerant spray hole 2110.

[0262] The inclined member IM may have an inclined surface INS. The inclined surface INS may be realized as a flat surface, a curved surface, or a combination thereof.

[0263] The inclined surface INS may contact a part of the composition inflow portion 1200. For example, the inclined surface INS may contact the inlet hole IH or may extend from the inlet hole IH.

[0264] The inclined surface INS may extend from the composition inflow portion 1200 to the vicinity of the refrigerant spray hole 2110. For example, the inclined surface INS may contact the refrigerant spray hole 2110.

[0265] The inclined surface INS may be designed in consideration of the spray shape of the refrigerant. For example, the inclined surface INS may be designed to correspond to the shape of the main flow MS.

[0266] Alternatively, the inclined surface INS may be realized in a shape having an inclination with a predetermined angle.

[0267] The inclined member IM may be integrally formed with the mixing portion 1100. Specifically, the inclined member IM may be understood as a portion having an inclination on a part of the inner surface of the mixing portion 1100.

[0268] The blocking member BM may be produced separately from the mixing portion 1100 and may be coupled to the inner surface of the mixing portion 1100. Specifically, the inclined member IM may be disposed in the shape of an inclined block or an inclined plate on the inner surface of the mixing portion 1100.

[0269] The composition introduced into the inlet hole IH may climb the inclined surface INS of the inclined member IM and may be sprayed by the main flow MS of the refrigerant while climbing. As a result, the composition may be sprayed by the refrigerant before agglomerating.

[0270] On the other hand, when the inclined member IM is used, the composition used in the spray needs to have a relatively high freezing point. This is because the temperature of the inclined member IM can be decreased by the sprayed refrigerant, and thus the temperature of the composition moving on the inclined member IM also decreases, resulting in the problem that the frozen composition is sprayed.

[0271] 4.2. Possible Problem #2 and Solution Plan As described above, when the mixing module 1000 is designed such that the composition reaches the main stream MS of the refrigerant, aggregation of the composition can be prevented, but a phenomenon may occur in which the composition is not uniformly mixed with the refrigerant.

[0272] Specifically, when the blocking member BM is used in the mixing module 1000 as shown in FIG. 10, the composition can be sprayed so as to incline to a part (for example, the lower part) of the main stream MS of the refrigerant as shown in the mixing part cross section 1100s perpendicular to the central axis of the mixing part 1100.

[0273] When the purpose is for the composition to be uniformly dispersed and sprayed throughout the entire main stream MS rather than being concentratedly sprayed in one area, it is necessary to prevent the above phenomenon from occurring.

[0274] In order to solve the above-described problem, it is necessary to guide the composition to move to the upper part of the main stream MS of the refrigerant beyond reaching the lower part of the main stream MS.

[0275] For this purpose, the mixing module 1000 may include a guide member. The guide member provides a surface on which the composition moves, and the surface may be shaped such that the composition will move to the upper part of the main stream MS.

[0276] Specifically, the guide member may be realized in a shape that surrounds at least a part of the refrigerant. For example, the guide member may be realized in a shape that surrounds at least a part of the main flow MS. In this case, the guide member can avoid the spray turbulence of the refrigerant and enable the composition to diffuse to the upper part of the main flow MS.

[0277] Hereinafter, various embodiments of the guide member will be described with reference to FIGS. 11 to 19. On the other hand, it is pre-disclosed that the guide member can be variously called a guide plate, a diffusion film, a metal film, a diffusion plate, a heat exchange guiding member, a heat transfer member, an insert, etc. according to its shape or function.

[0278] FIG. 11 is a diagram showing a guide plate 1610 according to one embodiment.

[0279] FIG. 12 is a diagram showing a process in which the composition moves through the guide plate 1610 according to one embodiment.

[0280] FIG. 13 is a diagram showing the shape of the guide plate 1610 based on the mixing section 1100 and the first plate 1611 of the guide plate 1610 according to one embodiment.

[0281] The guide plate 1610 may be disposed in the mixing section 1100 of the mixing module 1000 so as to guide the movement of the composition. Hereinafter, it is described that the guide plate 1610 is produced separately from the mixing section 1100 and is coupled to the mixing section 1100. However, the technical concept of the specification is not limited to the above description, and the guide plate 1610 may be realized in a state of being physically integrated with the mixing section 1100.

[0282] The guide plate 1610 can be understood as a structure composed of a plurality of surfaces. For example, referring to FIG. 11, the guide plate 1610 may include a first plate 1611 and a second plate 1612. In this regard, the expressions "first plate" and "second plate" 1611, 1612 are terms used to refer to components of the guide plate 1610, and can be expressed as the first and second parts, the first and second frames, the first and second structures, etc.

[0283] The first plate 1611 may have at least a first plate surface S11 and a second plate surface S12.

[0284] In this regard, the first plate surface S11 may mean a surface that contacts the inner surface of the mixing section 1100 when the first plate 1611 is disposed in the mixing section 1100. Specifically, the first plate 1611 is disposed near the inlet hole IH as shown in FIG. 11. In this regard, the first plate surface S11 may contact the inner surface of the mixing section 1100. The first plate surface S11 and the inner surface of the mixing section 1100 may be in planar contact or linear contact with each other.

[0285] The second plate surface S12 may mean a surface inclined at a preset angle with respect to the inlet hole IH when the first plate 1611 is disposed in the mixing section 1100. In other words, the second plate surface S12 may have a preset angle with respect to the plane including the inlet hole IH. In this regard, the first plate surface S11 and the second plate surface S12 may have a specific angle between them. The composition introduced through the inlet hole IH may move on the second plate surface S12 by adhering to the second plate surface S12.

[0286] The first plate surface S11 and the second plate surface S12 may be in the shape of a plane, a curved surface, or a combination thereof.

[0287] The first plate surface S11 and the second plate surface S12 may be directly and indirectly connected to each other.

[0288] The first plate surface S11 and the second plate surface S12 may intersect each other. In other words, the first plate surface S11 and the second plate surface S12 may contact each other or may share one edge.

[0289] The first plate surface S11 and the second plate surface S12 may not intersect each other. In this case, an additional surface may be located between the first plate surface S11 and the second plate surface S12. In this regard, the plane including the first plate surface S11 and the plane including the second plate surface S12 may intersect each other or may be parallel to each other.

[0290] In addition to the first plate surface S11 and the second plate surface S12 described above, the first plate 1611 may have an additional surface.

[0291] The first plate 1611 may be realized in various shapes. As an example, the first plate 1611 may be realized in a shape bent or folded at a predetermined angle as shown in FIG. 11. As another example, the first plate 1611 may be realized in various shapes such as a rectangular parallelepiped shape, a shape having a curved surface, and the like.

[0292] The second plate 1612 may have at least a third plate surface S13 and a fourth plate surface S14.

[0293] In this regard, the third plate surface S13 may mean the surface that contacts the inner surface of the mixing part 1100 when the second plate 1612 is disposed in the mixing part 1100. Specifically, the second plate 1612 is disposed near the inlet hole IH as shown in FIG. 11, and in this regard, the third plate surface S13 may contact the inner surface of the mixing part 1100. The third plate surface S13 and the inner surface of the mixing part 1100 may be in planar contact or linear contact with each other.

[0294] The fourth plate surface S14 may mean a surface inclined at a preset angle with respect to the inlet hole IH when the second plate 1612 is disposed in the mixing part 1100. In other words, the fourth plate surface S14 may have a preset angle with respect to the plane including the inlet hole IH. In this regard, the third plate surface S13 and the fourth plate surface S14 may have a specific angle therebetween. The composition introduced through the inlet hole IH may move on the fourth plate surface S14 by adhesion to the fourth plate surface S14.

[0295] The third plate surface S13 and the fourth plate surface S14 may be in the shape of a plane, a curved surface, or a combination thereof.

[0296] The third plate surface S13 and the fourth plate surface S14 may be directly and indirectly connected to each other.

[0297] The third plate surface S13 and the fourth plate surface S14 may intersect with each other. In other words, the third plate surface S13 and the fourth plate surface S14 may contact each other or share one edge.

[0298] The third plate surface S13 and the fourth plate surface S14 may not intersect with each other. In this case, an additional surface may be provided between the third plate surface S13 and the fourth plate surface S14. In this regard, the plane including the third plate surface S13 and the plane including the fourth plate surface S14 may intersect with each other or may be parallel to each other.

[0299] The second plate 1612 may have additional surfaces in addition to the third plate surface S13 and the fourth plate surface S14 described above.

[0300] The second plate 1612 may be realized in various shapes. As an example, the second plate 1612 may be realized in a shape bent or folded at a predetermined angle as shown in FIG. 11. As another example, the second plate 1612 may be realized in various shapes such as a rectangular parallelepiped shape, a shape having a curved surface, etc.

[0301] The first plate 1611 and the second plate 1612 may be arranged to have a specific local relationship in the mixing section 1100. As an example, referring to FIG. 11(a) or FIG. 12, the first plate 1611 and the second plate 1612 may be arranged to be separated from each other. In this regard, the inlet hole IH may be located between the first plate 1611 and the second plate 1612.

[0302] The first plate 1611 and the second plate 1612 may be arranged symmetrically with respect to each other in the mixing section 1100.

[0303] On the other hand, the guide plate 1610 may include only one of the first plate 1611 and the second plate 1612.

[0304] Referring to FIG. 13, the composition introduced through the inlet hole IH can move on the guide plate 1610. The composition moving on the guide plate 1610 can be mixed with the main stream MS of the refrigerant that will be sprayed together. As described below, when the height of the guide plate 1610 is high enough, the composition can reach the upper part of the main stream MS. Therefore, the composition is mixed with the refrigerant not only in the lower part but also in the upper part of the main stream MS, and as a result, the composition can be uniformly dispersed throughout the main stream MS.

[0305] As described above, in order for the composition to move on the guide plate 1610 and reach the upper part of the main stream MS, the guide plate 1610 needs to be designed to have a specific size.

[0306] Referring to FIG. 13(a), the guide plate 1610 can be designed to have a predetermined height, a predetermined distance, and a predetermined inclination angle.

[0307] The height of the guide plate 1610 can mean the height when the guide plate 1610 is disposed in the mixing section 1100. As an example, the first plate 1611 may have a first height H1 in a direction perpendicular to the central axis of the mixing section 1100 based on the inlet hole IH. The second plate 1612 may have a second height H2 in a direction perpendicular to the central axis of the mixing section 1100 based on the inlet hole IH.

[0308] The distance of the guide plate 1610 can mean the distance from the central part of the mixing section 1100 when the guide plate 1610 is disposed in the mixing section 1100. As an example, the first plate 1611 may have a first distance D1 from the central axis of the mixing section 1100. In this regard, the first distance D1 can be understood as the minimum distance from the central axis of the mixing section 1100 to the first plate 1611, but is not limited thereto. The second plate 1612 may also have a second distance D2 from the central axis of the mixing section 1100.

[0309] The inclination angle of the guide plate 1610 may mean the angle with respect to the inlet hole IH while the guide plate 1610 is disposed in the mixing section 1100. As an example, the second plate surface S12 of the first plate 1611 may have a first inclination angle IA1 based on the surface including the inlet hole IH or a surface parallel to the inlet hole IH. Further, the second plate 1612 may also have a second inclination angle IA2.

[0310] Referring to FIG. 13(b), the guide plate 1610 may be designed to have a predetermined length.

[0311] The length of the guide plate 1610 may be defined in a direction parallel to the central axis of the mixing section 1100. For example, as shown in FIG. 13(b), the first plate 1611 extends from the first plate end 1611a to the second plate end 1611b and has a first length L1. In this regard, the first length L1 may be understood as the length of a straight line connecting the point of the first plate end 1611a to the point of the second plate end 1611b among the straight lines parallel to the central axis of the mixing section 1100. The second plate 1612 may also extend from the third plate end to the fourth plate end and may have a second length.

[0312] The height and distance of the guide plate 1610 may be designed based on the internal structure of the mixing section 1100. However, the mixing section 1100 may have a third height H3 based on the inlet hole IH and is assumed to have a preset width W. It is assumed that the central axis of the mixing section 1100 is equal to the central axis CA of the refrigerant spray unit 2100.

[0313] The height of the guide plate 1610 may preferably be designed to be equal to or higher than half of the height of the mixing section 1100. For example, the first height H1 of the first plate 1611 and / or the second height H2 of the second plate 1612 may be equal to or higher than half of the third height H3 of the mixing section 1100. Thereby, as described above, it becomes possible for the composition to reach the upper part of the main flow MS of the refrigerant.

[0314] The distance of the guide plate 1610 is preferably designed to be equal to or higher than 1 / 4 of the width W of the mixing section. As an example, the first distance D1 of the first plate 1611 and / or the second distance D2 of the second plate 1612 may be equal to or higher than 1 / 4 of the width W of the mixing section. This is because the width of the guide plate 1610 is designed according to the first distance D1 and the second distance D2, and when the width of the guide plate 1610 is excessively reduced to be smaller than the maximum size of the cross-section of the main flow MS of the refrigerant, the refrigerant spray deteriorates, and the temperature of the refrigerant in the guide plate 1610 decreases and the composition freezes.

[0315] The inclination angle of the guide plate 1610 may be determined between 0° and 90°. As an example, the first inclination angle IA1 of the second plate surface S12 of the first plate 1611 with respect to the inlet hole IH may be determined between 0° and 90°. However, when the first inclination angle IA1 is 0°, the first plate surface S11 and the second plate surface S12 are substantially parallel to each other, and it is necessary to provide an additional surface between the first plate surface S11 and the second plate surface S12. The second inclination angle IA2 of the second plate 1612 can also be described in the same way as that described for the first inclination angle IA1.

[0316] The length of the guide plate 1610 may be shorter than the length of the inner surface of the mixing section 1100, but is not limited thereto. As an example, the first length L1 of the first plate 1611 may be shorter than the distance from the first end 1100a to the second end 1100b of the mixing section 1100. The length of the guide plate 1610 may be equal to or higher than a predetermined value in consideration of the degree of diffusion of the composition introduced through the inlet hole IH.

[0317] On the one hand, when the guide plate 1610 is used, the composition used in the spray needs to have a relatively high freezing point. This is because the temperature of the guide plate 1610 can be decreased by the sprayed refrigerant, and thus the temperature of the composition moving on the guide plate 1610 also decreases, resulting in the problem that the frozen composition is sprayed.

[0318] FIG. 14 is a diagram showing a diffusion film 1620 according to one embodiment.

[0319] Referring to FIG. 14, the diffusion film 1620 may extend from a first film end 1620a to a second film end 1620b and may have an inner surface IS and an outer surface OS.

[0320] The diffusion film 1620 may be attached to and removed from the mixing part 1100 of the mixing module 1000. Alternatively, the diffusion film 1620 may be realized to be integrated with the mixing part 1100 such that the diffusion film 1620 can form a part of the mixing part 1100.

[0321] The diffusion film 1620 may be manufactured using a bent or curved plate, but the present specification is not limited thereto.

[0322] The outer surface OS of the diffusion film 1620 may have a contact part. The contact part may mean the part where the diffusion film 1620 contacts the inner surface of the mixing part 1100 when the diffusion film 1620 is attached to the mixing part 1100.

[0323] The contact part of the diffusion film 1620 may have a first film surface S21. The first film surface S21 may be understood as the same component as the first plate surface S11 of the guide plate 1610 described above. As an example, when the diffusion film 1620 is disposed near the inlet hole IH, the first film surface S21 may contact the inner surface of the mixing part 1100. The first film surface S21 and the inner surface of the mixing part 1100 may be in planar contact or linear contact with each other.

[0324] The inner surface IS of the diffusion film 1620 may have an inclined portion. The inclined portion may mean a portion where the composition moves thereon. The outer surface OS and the inner surface IS of the diffusion film 1620 may face each other.

[0325] The inclined portion of the diffusion film 1620 may have a second film surface S22. The second film surface S22 is a surface inclined at a preset angle with respect to the inlet hole IH when the diffusion film 1620 is disposed in the mixing section 1100, and can be understood as a surface for guiding the movement of the composition. In other words, the second film surface S22 may have a preset angle with respect to the plane including the inlet hole IH. In this regard, the first film surface S21 and the second film surface S22 may have a specific angle therebetween.

[0326] The first film surface S21 and the second film surface S22 may be directly and indirectly connected to each other.

[0327] The first film surface S21 and the second film surface S22 may intersect each other. In other words, the first film surface S21 and the second film surface S22 may be bent from each other and may share one edge.

[0328] The first film surface S21 and the second film surface S22 do not intersect each other, and in this case, an additional surface may exist between the first film surface S21 and the second film surface S22. In this regard, the plane including the first film surface S21 and the plane including the second film surface S22 may intersect each other or may be parallel to each other. Alternatively, the first film surface S21 and the second film surface S22 may face each other.

[0329] The diffusion film 1620 may have a third film surface and a fourth film surface. The description of the first film surface S21 may be equally applicable to the third film surface, and the description of the second film surface S22 may be equally applicable to the fourth film surface. However, the first film surface and the third film surface may be symmetric to each other based on the central axis of the diffusion film 1620, and the second film surface and the fourth film surface may be symmetric to each other based on the central axis of the diffusion film 1620.

[0330] The composition introduced through the inlet hole IH may move on the inner surface IS by adhering to the inner surface IS.

[0331] The outer surface OS of the diffusion film 1620 may be composed of one curved surface, a plurality of flat surfaces, a plurality of curved surfaces, or a combination thereof. Similarly, the inner surface IS of the diffusion film 1620 may be composed of one curved surface, a plurality of flat surfaces, a plurality of curved surfaces, or a combination thereof.

[0332] FIG. 15 is a view showing the front surface of the diffusion film 1620 according to one embodiment.

[0333] Referring to FIG. 15, the diffusion film 1620 may have a first portion 1621, a second portion 1622, and a third portion 1623. For the sake of convenience of description, each of the first to third portions 1621, 1622, and 1623 is an expression used to refer to a part of the diffusion film 1620, and may be called the first to third plates, the first to third frames, the first to third structures, etc.

[0334] It can be understood that the first portion 1621 and the second portion 1622 respectively correspond to the first plate 1611 and the second plate 1612 of the guide plate 1610. Specifically, the first portion 1621 and the second portion 1622 may be positioned such that the inlet hole IH is located therebetween, and the composition introduced through the inlet hole IH may move to the main flow MS of the refrigerant while riding on the first portion 1621 or the second portion 1622.

[0335] Unlike the guide plate 1610, the diffusion film 1620 may have a third portion 1623 that connects the first portion 1621 and the second portion 1622 to each other. In other words, the first through third portions 1621, 1622, and 1623 may be formed as a physical unity.

[0336] The third portion 1623 may have an arc shape. The third portion 1623 may be composed of one curved surface, a plurality of flat surfaces, a plurality of curved surfaces, or a combination thereof.

[0337] As described below, the third portion 1623 may guide the composition so as to be more uniformly mixed into the spray flow of the refrigerant.

[0338] FIG. 16 is a diagram showing a process in which a composition moves through the diffusion film 1620 according to one embodiment.

[0339] Referring to FIG. 16, the composition introduced through the inlet hole IH may move over the first portion 1621 and reach the third portion 1623, or may move over the second portion 1622 and reach the third portion 1623.

[0340] The composition may move in the order of the first portion 1621 - the third portion 1623 - the second portion 1622 or in the order of the second portion 1622 - the third portion 1623 - the first portion 1621 so as to be rotated based on the central axis of the diffusion film 1620. By rotating the composition, it may be possible to uniformly disperse the composition in the spray flow of the refrigerant.

[0341] Also, the third portion 1623 may prevent the composition from moving outside the main flow MS of the refrigerant.

[0342] The diffusion film 1620 can be manufactured by bending a flat plate as described above. As an example, the diffusion film 1620 can be manufactured by a step of preparing a square plate having a first edge and a second edge facing each other and a step of curving the square plate so that the first edge and the second edge face each other. In this regard, the first edge and the second edge may constitute the outer surface OS and may be included in the contact portion.

[0343] On the other hand, when the diffusion film 1620 is manufactured as described above, a gap may be formed between the first portion 1621 and the second portion 1622 of the diffusion film 1620 as shown in FIG. 14. When the diffusion film 1620 is manufactured in a mold for injecting a metal or the like into a specific shape, the first portion 1621 and the second portion 1622 may be directly connected to each other, and a gap therebetween may not be formed.

[0344] As shown again in FIG. 14, the diffusion film 1620 may have an inlet groove and a fixing groove CG.

[0345] The inlet groove is a groove corresponding to the inlet hole IH and may include a first inlet groove IG1 formed in the first portion 1621 and a second inlet groove formed in the second portion 1622.

[0346] The diffusion film 1620 may be fixed to the inner portion of the mixing section 1100 through the fixing groove CG. A connecting member (for example, a hook member) may be formed in the mixing section 1100 so as to correspond to the fixing groove CG. The fixing groove CG may be formed in the third portion 1623 of the diffusion film 1620, but is not limited thereto.

[0347] The diffusion film 1620 may have a preset radius of curvature.

[0348] FIG. 17 is a diagram showing the radius of curvature CR of the diffusion film 1620 according to one embodiment. Referring to FIG. 17, a part of the inner surface IS of the diffusion film 1620 may have a radius of curvature CR. The radius of curvature CR can be understood as the radius of curvature CR of the portion corresponding to the third portion 1623 among the inner surfaces IS of the diffusion film 1620.

[0349] The radius of curvature CR may be designed to be smaller than the width W of the mixing portion and equal to or larger than 1 / 4 of the width W. However, when the cross-section of the mixing portion 1100 is not a circle but an ellipse, the mixing portion 1100 may be designed differently, and the mixing portion 1100 may be determined empirically to correspond to the maximum size of the cross-section of the main flow MS of the refrigerant.

[0350] As an example, regarding the mixing portion 1100 that provides a mixing space having a specific shape, while the radius of curvature CR changes, an experiment is performed to observe the spot size of the refrigerant sprayed from the mixing module 1000 and whether the composition freezes or not, and the optimal value of the radius of curvature CR can be determined empirically.

[0351] The diffusion film 1620 may have a film width FW. The film width FW can be understood as the maximum width in the horizontal direction of the diffusion film 1620. As an example, the film width FW may be twice the radius of curvature CR.

[0352] On the other hand, the diffusion film 1620 may have a predetermined length. The length of the diffusion film 1620 can be understood as being equal to the first length L1 of the guide plate 1610 described above.

[0353] FIG. 18 is a diagram showing the diffusion film 1620 according to one embodiment.

[0354] The diffusion film 1620 may be realized such that its cross-section has the shape of a keyhole. Specifically, as shown in FIG. 18, the first portion 1621 of the diffusion film 1620 may have a first film surface S21 in contact with the inlet hole IH and a second film surface S22 substantially perpendicular to the cross-section of the inlet hole IH. Similarly, the second portion 1622 of the diffusion film 1620 may have a third film surface S23 in contact with the inlet hole IH and a fourth film surface S24 substantially perpendicular to the cross-section of the inlet hole IH.

[0355] In addition to this, the diffusion film 1620 may have various shapes. As an example, the diffusion film 1620 may have a shape in which the width narrows or expands in the direction from the first film end 1620a to the second film end 1620b. Also, the cross-sectional shape of the diffusion film 1620 may be realized in various ways, such as a circular shape, an elliptical shape, a polygonal shape, or a shape composed of a combination of straight lines and curves.

[0356] FIG. 19 is a diagram showing various shapes of a guide member according to one embodiment.

[0357] Referring to FIG. 19(a), the guide wall 1630 may protrude from the inner surface of the mixing portion 1100. Specifically, the guide wall 1630 may be formed on both sides with the inlet hole IH intervening therebetween, and the surface of the guide wall 1630 may be designed to be equal to the second plate surface S12 of the first plate 1611 and the fourth plate surface S14 of the second plate 1612 described above. In this regard, based on the inlet hole IH, the height of the guide wall needs to be designed to be equal to or higher than 1 / 2 of the second height H2 of the mixing portion 1100.

[0358] Referring to FIG. 19(b), the guide plate 1610 may further include a third plate 1613. The third plate 1613 may connect the first plate 1611 and the second plate 1612 to each other such that there is no gap between the first plate 1611 and the second plate 1612. The third plate 1613 may have a hole corresponding to the inlet hole IH. Since the guide plate 1610 further includes the third plate 1613, the composition introduced through the inlet hole IH may move to the first plate 1611 or the second plate 1612 through the third plate 1613. In other words, it is an advantage that the composition can move on the guide plate 1610 not only laterally but also in all directions to the main flow MS of the refrigerant.

[0359] 4.3. Possible Problem #3 and Solution Plan When the freezing point of the composition is relatively high, the temperature of the main flow MS of the refrigerant is relatively low, and thus the frozen composition may be sprayed, as described above.

[0360] To solve the problem of the composition freezing, it is possible to consider a method of adding heat to the mixing section 1100 to increase the temperature of the mixing section 1100 or a method of directly increasing the temperature of the composition. However, these methods may result in deterioration of the cooling effect of the refrigerant or a decrease in quality or an increase in the manufacturing cost of the product due to the need for an additional heating device.

[0361] Hereinafter, with reference to FIGS. 20 to 23, the design direction of the mixing module 1000 for preventing the freezing of the composition without inhibiting the cooling effect as much as possible and without using a separate device will be described.

[0362] The basic principle is as follows. The internal space of the mixing section 1100 is divided into a region corresponding to the main flow MS of the refrigerant and other regions, and a region where outside air having a relatively high temperature compared to the refrigerant is separated circulates continuously, thereby preventing the composition from freezing.

[0363] FIG. 20 is a diagram showing a diffusion film 1620 having a vent hole VH according to one embodiment.

[0364] FIG. 21 is a diagram showing a process in which outside air is introduced into and circulated in a mixing module 1000 according to one embodiment.

[0365] FIG. 22 is a cross-sectional view showing a mixing unit 1100 to which the diffusion film 1620 is attached according to the above embodiment.

[0366] As shown in FIG. 20, the diffusion film 1620 described in FIG. 14 may be used, and vent holes VH may be formed in the diffusion film 1620.

[0367] Referring to FIG. 21, when the diffusion film 1620 is attached to the mixing unit 1100, the internal space of the mixing unit 1100 may be divided into a first region A1 inside the diffusion film 1620 and a second region A2 outside the diffusion film 1620. In this regard, the first region A1 may be understood as the region where the main flow MS of the refrigerant is located. As the refrigerant is sprayed, the pressure in the internal space of the mixing unit 1100 decreases as a whole, whereby air outside the mixing unit 1100 may be introduced into the mixing unit 1100. In this regard, as the refrigerant is sprayed into the first region A1, outside air may be introduced into the second region A2 instead of the first region A1 as shown in FIG. 21(a).

[0368] As shown in FIG. 21(b), the outside air introduced into the second region A2 may move to the vent holes VH formed in the diffusion film 1620. This means that the closer the vent holes VH are formed to the first film end portion 1620a of the diffusion film 1620, the more the outside air can move to the vicinity of the internal space of the mixing unit 1100 or the refrigerant spray holes 2110.

[0369] Next, the outside air may be introduced into the first region A1 through the vent holes VH, and as a result, the outside air may be discharged outside the mixing unit 1100 together with the refrigerant.

[0370] In other words, due to the ventilation holes VH formed in the diffusion film 1620, outside air having a relatively higher temperature than the refrigerant can continuously circulate from the second region A2 - ventilation hole VH - the first region A1, and the circulated outside air can supply heat to the diffusion film 1620 while passing through the outer surface OS of the diffusion film 1620.

[0371] The diffusion film 1620 can be supplied with heat from the outside air and transfer the heat to the composition moving on the diffusion film 1620. Since heat is transferred to itself, the composition can be sprayed without freezing.

[0372] Referring to FIG. 20 again, the ventilation holes VH may be formed near the first film end 1620a rather than the second film end 1620b of the diffusion film 1620. Also, the ventilation holes VH may be formed near the first film end 1620a rather than at the midpoint between the first film end 1620a and the second film end 1620b of the diffusion film 1620. Therefore, the outside air can be discharged after being moved into the internal space of the mixing part 1100, and thus, the diffusion film 1620 can be supplied with heat from the outside air as a whole.

[0373] Referring to FIG. 22, in a state where the diffusion film 1620 is attached to the mixing part 1100, the ventilation holes VH may be located near the first end 1100a rather than the second end 1100b of the mixing part 1100. Alternatively, the ventilation holes VH may be located between the inlet hole IH and the first end 1100a. Alternatively, the ventilation holes VH may be located between the inlet hole IH and the first end 1100a and near the first end 1100a rather than the inlet hole IH.

[0374] The ventilation holes VH may be formed in each of the left and right portions of the diffusion film 1620. Alternatively, the ventilation holes VH may be formed in one of the left or right portions of the diffusion film 1620.

[0375] The ventilation holes VH may be realized in various shapes. As an example, the ventilation holes VH may have a circular shape, a polygonal shape, or an elliptical shape.

[0376] As described above, in order for the diffusion film 1620 to be supplied with heat from the outside air and transfer the supplied heat to the composition, the thermal conductivity of the diffusion film 1620 needs to be equal to or higher than a predetermined value.

[0377] As a result of experiments using various metals in terms of thermal conductivity, copper (Cu), aluminum (Al), and stainless steel (SUS) do not cause freezing of the composition. Therefore, according to one example, the diffusion film 1620 may be composed of copper (Cu), aluminum (Al), stainless steel (SUS), or a combination thereof. Alternatively, as another example, the thermal conductivity of the diffusion film 1620 may be higher than the thermal conductivity of SUS. Specifically, the diffusion film 1620 may have a thermal conductivity equal to or higher than 12 W / m·K.

[0378] Furthermore, in order to efficiently perform heat transfer of the diffusion film 1620, the thickness of the diffusion film 1620 also needs to be smaller than or equal to a predetermined value. As an example, the thickness of the diffusion film 1620 may be approximately smaller than or equal to 1.0 mm. Preferably, the thickness of the diffusion film 1620 may be smaller than or equal to 0.5 mm. More preferably, the thickness of the diffusion film 1620 may be approximately 0.3 mm.

[0379] On the other hand, even when the ventilation holes VH are not formed in the diffusion film 1620, the circulation of the outside air can be induced.

[0380] FIG. 23 is a diagram showing a state in which the diffusion film 1620 is disposed in the mixing unit 1100 so as to form a gap between the diffusion film 1620 and the refrigerant spray holes 2110 according to one embodiment.

[0381] Referring to FIG. 23, the diffusion film 1620 may be disposed in the mixing section 1100 such that a gap is formed between the first film end 1620a of the diffusion film 1620 and the refrigerant spray holes 2110. For example, when the diffusion film 1620 is disposed in the mixing section 1100, the first film end 1620a of the diffusion film 1620 may be spaced apart from the refrigerant spray holes 2110 by a preset distance in the distal direction (e.g., the spray direction of the refrigerant). Alternatively, the first film end 1620a may be spaced apart from the first end 1100a of the mixing section 1100 by a preset distance in the distal direction.

[0382] On the other hand, the shape of the first film end 1620a of the diffusion film 1620 may be designed to form a space between the diffusion film 1620 and the first end 1100a when the diffusion film 1620 is disposed in the mixing section 1100.

[0383] In this regard, the length of the diffusion film 1620 may be shorter than the length of the mixing section 1100, but is not limited thereto.

[0384] The gap or space formed between the diffusion film 1620 and the first end 1100a of the mixing section 1100 or the refrigerant spray holes 2110 may function as the ventilation hole VH described above.

[0385] 4.4. Selective Use of Guide Members As described above, the guide member can solve problems that may occur when mixing and spraying the refrigerant and the composition in the mixture spraying system 100.

[0386] The shape of the guide member for solving any problem can be various, and depending on the characteristics of the composition, a guide member having a desired shape can be used (for example, a shape that is attached to or integrated with the mixing module 1000). As an example, when the viscosity and cohesive force of the composition are relatively low and the freezing point is relatively low, the guide member may not be necessary. As another example, when the viscosity and cohesive force of the composition are relatively high and the freezing point is relatively low, the guide plate 1610, the diffusion film 1620, or the diffusion film 1620 having ventilation holes VH may be used. As another example, when the freezing point of the composition is relatively high, the diffusion film 1620 having ventilation holes VH may be used.

[0387] 5. Connection of the Mixing Module and the Refrigerant Supply Device Hereinafter, the process of coupling the mixing module 1000 and the refrigerant supply device 2000 to each other and the components necessary therefor will be described with reference to FIGS. 24 and 25. Further, the components for attaching the guide member to the mixing module 1000 will be described with reference to FIG. 26.

[0388] FIG. 24 is a diagram showing a process in which a mixing module 1000 is attached to a refrigerant spray unit 2100 according to one embodiment.

[0389] Referring to FIG. 24, the mixing module 1000 may include a first fixing member 1520, and the refrigerant spray unit 2100 may include a second fixing member 2130.

[0390] The first fixing member 1520 may be formed on the fixing portion 1500 of the mixing module 1000. The first fixing member 1520 may be a hook member. Alternatively, the first fixing member 1520 may have a locking protrusion.

[0391] The second fixing member 2130 may be formed on the outer surface of the refrigerant spray unit 2100. The second fixing member 2130 may include a groove or a hole.

[0392] The first fixing member 1520 of the mixing module 1000 and the second fixing member 2130 of the refrigerant spray unit 2100 may be coupled to each other. As an example, since the refrigerant spray unit 2100 is inserted into the mixing module 1000 in a sliding manner, the locking portion of the first fixing member 1520 may be caught by the groove of the second fixing member 2130.

[0393] The refrigerant spray unit 2100 may have an O-ring 2120. The O-ring 2120 may strengthen the connection between the refrigerant spray unit 2100 and the mixing module 1000 and may function as a sealing functional portion as described below. The O-ring 2120 may be positioned between the refrigerant spray hole 2110 and the second fixing member 2130. Accordingly, the mixing module 1000 can be prevented from being separated from the refrigerant spray unit 2100 without permission.

[0394] FIG. 25 is a diagram showing a process of performing sealing when the mixing module 1000 is coupled to the refrigerant spray unit 2100 according to one embodiment.

[0395] Referring to FIG. 25, when the refrigerant spray unit 2100 is inserted into the mixing module 1000, the front portion (the portion including the refrigerant spray hole 2110) of the refrigerant spray unit 2100 is inserted into the insertion hole SH of the support portion 1510, and thus the support portion 1510 can support the refrigerant spray hole 2110.

[0396] On the other hand, when the refrigerant is sprayed from the refrigerant spray unit 2100, a part of the refrigerant may flow so as to recede in a direction opposite to the spray direction of the refrigerant in the mixing portion 1100. The support portion 1510 can prevent the refrigerant flowing backward from reaching the refrigerant spray unit 2100.

[0397] Furthermore, referring to FIG. 25(b), the O-ring 2120 of the refrigerant spray unit 2100 can prevent outside air from being introduced into the gap between the mixing module 1000 and the refrigerant spray unit 2100.

[0398] As described above, the support portion 1510 and the O-ring 2120 reduce the risk caused by the refrigerant flowing backward or the inflow of outside air, and improve the stability of the fixation between the mixing module 1000 and the refrigerant spray unit 2100.

[0399] FIG. 26 is a diagram showing components of the guide member 1000 to be attached to the mixing module according to one embodiment. Hereinafter, although this specification describes that the guide member is the diffusion film 1620, the technical concept of this specification is not limited thereto.

[0400] The mixing module 1000 may include at least one protrusion. As an example, referring to FIG. 26, the first to fifth protrusions 1131, 1132, 1133, 1134, and 1135 may be included in the inner portion of the mixing portion 1100.

[0401] The protrusion can be understood as a component that functions to support a specific object such as a rib or a rail.

[0402] The protrusion may support the diffusion film 1620. Specifically, the protrusion may support the diffusion film 1620 so that it does not sway within the mixing portion 1100. As an example, when the diffusion film 1620 is attached to the mixing module 1000, the first protrusion 1131 supports the first portion 1621 of the diffusion film 1620, and the second to fourth protrusions 1132, 1133, and 1134 support the third portion 1623 of the diffusion film 1620, and the fifth protrusion 1135 may support the second portion 1622 of the diffusion film 1620.

[0403] The protrusion may be designed to correspond to the shape of the diffusion film 1620.

[0404] The plurality of protrusions may be formed symmetrically based on the central axis of the mixing portion 1100, but are not limited thereto.

[0405] Each protrusion may have a specific length in a direction parallel to the central axis of the mixing part 1100 in the mixing part 1100. The length of the protrusion may be shorter than the length of the inner part of the mixing part 1100.

[0406] 6. Design of Mixing Module Considering Spray Amount As described above, in the mixture spray system 100, the composition can move by the generation of negative pressure according to the spray of the refrigerant. As a result, the spray amount of the composition is partly determined according to the spray amount of the refrigerant.

[0407] In this situation, if the amount of the composition or the spray amount of the composition and the amount of the refrigerant or the spray amount of the refrigerant are not accurately controlled, only the refrigerant may be sprayed due to the lack of the composition, or all of the required amount of the composition (for example, the amount of the composition required for one procedure or one treatment) may not be sprayed due to the lack of the refrigerant.

[0408] In other words, when designing a device for spraying the refrigerant and the composition together, the "same consumption time condition" that the time required for consuming a specific amount (for example, ampoule capacity) of the composition and the time required for consuming a specific amount (for example, cartridge capacity) of the refrigerant are substantially the same should be satisfied.

[0409] FIG. 27 is a diagram showing the mixing module 1000 marked with elements affecting the spray amount of the composition according to one embodiment.

[0410] Referring to FIG. 27, the consumption time of the composition and the consumption time of the refrigerant may be affected by the capacity of the refrigerant cartridge CTR, the refrigerant pressure (for example, the internal pressure of the cartridge CTR), the size of the refrigerant spray hole 2110, the width W of the mixing part, the width of the guide member (for example, the film width FW), the tube width TW of the tube 1210, and the characteristics of the composition (for example, the composition viscosity).

[0411] Hereinafter, for the convenience of explanation, this specification describes that the guide member is the diffusion film 1620, but the technical concept of the specification is not limited thereto.

[0412] Among the influencing factors mentioned above, after specifying the value of a factor that is difficult to control, the value of a factor that can be controlled may be designed in consideration of the value of the specified factor and the "same conditions of consumption time".

[0413] First, the type of the composition may be specified. The type of the composition may be specified according to the type of the provided procedure or treatment. The provided treatment is arbitrarily difficult to change, and thereby, the type of the composition is also difficult to change, and the characteristics of the composition such as the viscosity of the composition can be understood as unique values.

[0414] Furthermore, the amount of the composition can be determined according to the type of the provided procedure or treatment or the type of the commercially available composition container, and the amount of the refrigerant can be determined according to the capacity of the cartridge CTR. Therefore, the amount of the composition and the amount of the refrigerant are arbitrarily difficult to control, and this can be understood as unique values.

[0415] Next, the width W of the mixing section may be designed. The width W of the mixing module 1000 can be determined in consideration of the size of the refrigerant supply device 2000, the size of the refrigerant spray unit 2100 or the refrigerant spray hole 2110, and / or the spray amount of the composition. As an example, as the refrigerant supply device 2000 or the refrigerant spray hole 2110 increases, the width W of the mixing section can increase. On the other hand, as the width W of the mixing section increases, the spray amount of the composition increases, and thus, the width W of the mixing section can be readjusted later.

[0416] In consideration of the designed width W of the mixing section, the film width FW of the diffusion film 1620 may be designed. The diffusion film 1620 may preferably be formed so as to surround the main flow MS of the refrigerant, and the size of the main flow MS of the refrigerant is changed according to the size of the refrigerant spray hole 2110, and thus, the film width FW may be designed in consideration of the size of the refrigerant spray hole 2110.

[0417] Finally, the tube width TW may be designed. In this regard, as the tube width TW increases, the spray amount of the composition increases, which can be considered.

[0418] To design the mixing module 1000 that satisfies the same condition of consumption time, some of the variables mentioned above are set as independent variables, and an experiment can be conducted to monitor whether the same condition of consumption time is satisfied while changing the independent variables.

[0419] The mixing module 1000 or the diffusion film 1620 may be designed using the values of the variables calculated in the conducted experiment.

[0420] As an example, when the capacity of the cartridge CTR, the pressure of the refrigerant, the size of the refrigerant spray hole 2110, the width W of the mixing section, and the film width FW are fixed as specific values and the type of the composition and the required usage amount of the composition are determined, while changing the tube width TW, monitor whether the consumption time of the refrigerant and the consumption time of the composition are substantially the same, and the value of the tube width TW when the same condition of consumption time is satisfied may be calculated.

[0421] The mixing module 1000 may be designed to have the calculated value of the tube width TW and the specified width W of the mixing section, and the diffusion film 1620 may be designed to have the specified film width FW.

[0422] As another example, when the capacity of the cartridge CTR, the pressure of the refrigerant, the size of the refrigerant spray hole 2110, the width W of the mixing section, and the tube width TW are fixed as specific values and the type of the composition and the required usage amount of the composition are determined, while changing the film width FW, monitor whether the consumption time of the refrigerant and the consumption time of the composition are substantially the same, and the value of the film width FW when the same condition of consumption time is satisfied may be calculated.

[0423] The diffusion film 1620 may be designed to have the calculated film width FW, and the mixing module 1000 may be designed to have the specified tube width TW and the specified width W of the mixing section.

[0424] 7. Cover Design Hereinafter, with reference to FIG. 28, a cover COV designed to protect the sensor unit 2600 of the refrigerant supply device 2000 will be described.

[0425] FIG. 28 is a diagram showing a process in which a cover and a mixing module are sequentially coupled to a main body according to one embodiment. Specifically, FIG. 28(a) is a diagram showing a process in which the cover COV is coupled to the main body (MB), and FIG. 28(b) is a diagram showing a process in which the mixing module 1000 is coupled to the refrigerant supply device 2000.

[0426] Referring to FIG. 28(a), a sensing hole SH may be formed in the main body MB. The sensing hole SH is a component that prevents the sensing region SR of the sensor unit 2600 embedded in the main body MB from being blocked. The sensing hole SH may be designed so that the sensing region SR of the sensor unit 2600 passes through it. In other words, the sensing path of the sensor unit 2600 may be ensured by the sensing hole SH.

[0427] On the other hand, when spraying the composition onto the target using the mixture spraying system 100, part of the sprayed composition may penetrate the target surface and be absorbed by the target, and part of the sprayed composition may hit the target surface and bounce back. Here, there is a possibility that the sensor unit 2600 may be contaminated, such as when the composition bounced through the sensing hole SH accumulates on the sensor unit 2600.

[0428] Furthermore, the refrigerant supply device 2000 may be used independently for a cooling procedure in which the refrigerant is sprayed onto the surface of the target. However, as described above, the refrigerant supply device 2000 may be used as the mixture spraying system 100 by combining with the mixing module 1000. When the refrigerant supply device 2000 is used as the mixture spraying system 100, precise temperature control of the target surface may not be essential. In other words, the measurement of the temperature of the target surface by the sensor unit 2600 may not be performed.

[0429] In view of the above, it is necessary to cover the sensing hole SH to prevent contamination of the sensor unit 2600. Referring to Fig. 28(a), the cover COV may be designed to have a cover portion SP for covering the sensing hole SH.

[0430] When the cover COV is coupled to the main body MB, the cover portion SP of the cover COV may cover at least a part of the sensing hole SH. For example, in Fig. 28(a), the height SPH of the cover portion may correspond to the diameter or width of the sensing hole SH. Regarding another example, in Fig. 28(a), the height SPH of the cover portion may be determined based on the distance between the nozzle 2100 and the sensing hole SH.

[0431] Referring to Fig. 28(b), while the mixing module 1000 is coupled to the refrigerant supply device 2000, the sensing hole SH may be covered. Specifically, since the cover COV is coupled to the main body MB, at least a part of the sensing hole SH is covered. However, since the mixing module insertion portion MI is provided in the cover COV, there may be a possibility that the composition may flow into the mixing module insertion portion MI. At this time, when the mixing module 1000 is coupled to the refrigerant supply device 2000, the mixing module insertion portion MI of the cover COV may be covered by the rear surface RS of the mixing module 1000. As a result, the sensing hole SH may be completely covered by the cover portion SP of the cover COV and the rear surface RS of the mixing module 1000.

[0432] 8. Example of Using a Mixture Spray System Hereinafter, with reference to FIG. 29, a process of spraying a refrigerant and a composition using a mixture spray system 100 will be described.

[0433] FIG. 29 is a diagram showing a process of using a mixture spray system according to one embodiment.

[0434] First, the user may fill the composition into the mixing module 1000. For example, referring to FIG. 29, the user may transfer the composition stored in the ampoule to the composition storage unit 1300 of the mixing module 1000 using a syringe.

[0435] The mixing module may include a composition injection hole CIH through which an injection needle passes and is fluidly connected to the composition storage unit 1300.

[0436] The user may couple the cartridge CTR in which the refrigerant is stored to the main body MB. Since the cartridge CTR is coupled to the cartridge coupling unit 2500 of the main body MB, the sealing portion of the cartridge CTR is opened so that the internal of the cartridge CTR and the refrigerant passage in the main body MB can be connected to each other.

[0437] The user may couple the mixing module 1000 to the refrigerant supply device 2000.

[0438] The order of the combination of the refrigerant supply device 2000 and the mixing module 1000 and the combination of the main body MB and the cartridge CTR may be arbitrarily determined. In other words, the user may combine the cartridge CTR after coupling the mixing module 1000 to the refrigerant supply device 2000, or the user may combine the mixing module 1000 to the refrigerant supply device 2000 after coupling the cartridge CTR to the main body MB.

[0439] On the one hand, the process of filling the composition into the mixing module 1000 may be executed after the mixing module 1000 is coupled to the refrigerant supply device 2000.

[0440] After the assembly of the mixture spraying system 100 is completed, the user can spray the composition and the refrigerant onto the target.

[0441] After the use of the mixture spraying system 100 is completed, the user may reverse the assembly process of the mixture spraying system 100 described above. For example, the user may separate the mixture spraying system 100 from the mixing module 1000 and the refrigerant supply device 2000, and remove the cartridge CTR from the refrigerant supply device 2000.

[0442] On the other hand, during the use of the mixture spraying system 100, a situation may occur where it is necessary to replace the cartridge CTR or the mixing module 1000. Here, one procedure may be determined based on whether the refrigerant stored in the cartridge CTR is discharged according to the use of the mixture spraying system 100. However, the technical concept of the present disclosure is not limited thereto, and one procedure may be determined based on whether to discharge the composition filled in the mixing module 1000.

[0443] During the use of the mixture spraying system 100, a situation may occur where the composition stored in the mixing module 1000 is discharged, but the refrigerant stored in the cartridge CTR is not discharged. In this case, the user can additionally fill the composition into the mixing module 1000 and spray the composition and the refrigerant until the refrigerant stored in the cartridge CTR is discharged. Alternatively, when a criterion regarding one procedure, such as whether all the composition in the mixing module 1000 has been consumed, is determined, the user can replace the cartridge CTR after spraying all the refrigerant in the cartridge CTR using the mixture spraying system 100.

[0444] There may be a case where the procedure treatment method is to sequentially spray a first composition and a second composition having different effects. In this case, the user fills the first mixing module with the first composition, then combines the refrigerant supply device 1000 to spray the refrigerant and the first composition, then fills the second mixing module with the second composition, and then combines the refrigerant supply device 1000 to spray the refrigerant and the second composition. In this case, the first partial procedure time for spraying the first composition and the second partial procedure time for spraying the second composition may be determined based on the procedure time when the refrigerant stored in the cartridge CTR is being discharged. Further, the amount of the first composition filled in the first mixing module may be determined in consideration of the first partial procedure time, and the amount of the second composition filled in the second mixing module may be determined in consideration of the second partial procedure time.

[0445] When a new procedure is to be executed after using the mixture spraying system 100, it is necessary to replace the cartridge (CTR). When a new procedure is to be executed, the previously used cartridge (CTR) may be replaced with a new cartridge (CTR) regardless of whether there is remaining refrigerant. This is because the procedure time is determined according to whether the refrigerant is consumed in the cartridge (CTR).

[0446] On the other hand, when replacing the cartridge CTR, the refrigerant remaining in the cartridge CTR needs to be sufficiently removed. For example, as described above, the user may operate the refrigerant supply device 2000 to spray the refrigerant until the spraying of the refrigerant stops, and then separate the cartridge CTR from the main body MB. For another example, the user separates the cartridge CTR from the main body MB, but does not completely separate it, and after the refrigerant remaining in the cartridge CTR is sufficiently discharged through the gap formed between the cartridge coupling unit 2500 of the main body MB and the cartridge CTR, the cartridge CTR can be completely separated.
