However, the present disclosure may have various changes and various embodiments, and hereinafter, specific embodiments will be shown in the drawings and described in detail.

[0133] In the drawings, for the sake of clarity, the thickness of layers and regions is exaggerated, and a component or layer is referred to as being "on" another component or another layer, including all cases where other layers or other components are inserted in the middle and directly on other components or layers. The same reference numerals are used throughout the specification to represent the same or similar components. In addition, components with the same functions within the scope of the same idea that appear in the drawings of the various embodiments will be described using the same reference numerals, and their repeated description will be omitted.

[0134] It should be understood that although the numbers first, second, etc. may be used merely as identifiers to distinguish one component from another.

[0135] In addition, considering the ease of writing the specification, the terms "module" and "unit" or component used in the following embodiments are given or used interchangeably, and they themselves do not have meanings or roles distinguished from each other.

[0136] As used herein, the singular forms are intended to include the plural forms as well, unless the context clearly indicates otherwise.

[0137] It should also be understood that the terms “comprises,” “includes,” “contains,” and / or “including,” when used herein, specify the presence of stated features, integers, steps, operations, elements, and / or components, but do not preclude the presence or addition of one or more other features, integers, steps, operations, elements, components, and / or groups thereof.

[0138] In the drawings, the size of components may be exaggerated or reduced for convenience of description, and for example, in the drawings, the size or thickness of components may be arbitrarily expressed for convenience of description, but the present disclosure is not limited thereto.

[0139] When the embodiment can be implemented in other ways, the specific process order can be performed differently from the described order. As an example, two processes described in succession can be performed substantially at the same time, or can be performed in the reverse order of the described order.

[0140] In the embodiments described below, when it is mentioned that a film, region, component, etc. is connected to another film, region, component, etc., the film, region, component, etc. can be directly connected to another film, region, component, etc., or the connection can be achieved indirectly through other films, regions, components, etc. in between.

[0141] 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, region, component, etc. can be directly electrically connected to the other film, region, component, etc., or it can be indirectly electrically connected through other films, regions, components, etc. in between.

[0142] In the embodiments described below, when it is mentioned that a membrane, region, component, etc. is fluidly connected to another membrane, region, component, etc., it will be understood that the membrane, region, component, etc. can form at least a part of the flow path through which the respective fluid flows.

[0143] For example, in this specification, component A is fluidly connected to component B, which may mean that the fluid passing through the flow path formed by component A can reach the flow path formed by component B, and 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, components A and component B may be considered to be fluidically connected to each other. Alternatively, when component A and component B are connected to each other through component C (e.g., a conduit), so that the flow path formed by component A and the flow path formed by component B are indirectly connected to each other through the flow channel formed by component C, components A and component B may be considered to be fluidically connected to each other. At this time, component C may be understood as fluidly connecting components A and B to each other. In addition, components A and component B may be fluidically connected to each other through multiple components.

[0144] The present invention relates to a mixing module for a refrigerant providing device. The mixing module is used to mix a composition with a refrigerant supplied from the refrigerant providing device to spray the refrigerant and the composition together. When the refrigerant and the composition are mixed together and the mixture is sprayed to a target, the composition with a relatively low temperature can be sprayed to the target.

[0145] Here, the concept of composition includes not only pharmacological compositions for medical purposes but also cosmetic compositions for cosmetic purposes, and the composition may refer to a material containing an active ingredient that causes or produces a medical effect or a cosmetic effect.

[0146] Here, as a refrigerant, a material that can apply cooling energy to the target area can be used, such as carbon dioxide (CO2), liquid nitrogen (LN), nitrogen dioxide (NO2), nitric oxide (NO), hydrofluorocarbon (HFC) series materials, methane (CH4), PFC, SF6, coolant, cooling gas, etc.

[0147] Here, "target" may refer to a body part on which a procedure, treatment or care is performed to produce a cosmetic effect or a medical effect. For example, the target may refer to body skin. Below, for the convenience of description, this specification is mainly described for the case where the target is body skin, but the scope and spirit of this specification are not limited thereto.

[0148] The degree of penetration of the composition into the body skin may be affected by the skin temperature. Specifically, when the skin temperature drops to a predetermined level, the skin cells shrink and the gaps between the skin cells increase, and the composition penetrates through the gaps between the skin cells, and as a result, the permeability of the composition can be improved.

[0149] Meanwhile, when the refrigerant and the composition are mixed and sprayed, various problems may occur, for example, condensation of the composition may cause a problem that the composition cannot be sprayed uniformly, a problem that the composition cannot be uniformly distributed in the spraying area of ​​the refrigerant, and a problem that the composition is frozen due to the refrigerant.

[0150] Here, a problem that the composition cannot be uniformly sprayed due to condensation of the composition or a problem that the composition cannot be uniformly distributed in a spraying area of ​​the refrigerant may cause permeation deterioration.

[0151] Specifically, in order for the composition to penetrate effectively, it is necessary to spray the composition with a sufficiently strong force (or pressure). When the size of the composition increases (or its mass increases), and 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 will decrease. In other words, the total energy possessed by the sprayed refrigerant is divided and shared by the composition. At this time, since the composition is divided into particles of more uniform size, the composition can be sprayed with a stronger force (or a faster speed), thereby improving permeability.

[0152] Furthermore, the problem of freezing of the composition by the refrigerant may render the mixture injection system or the mixing module inoperable or cause inconvenience to the person being treated.

[0153] In this specification, a hybrid module having improved permeability and convenience by eliminating the above-mentioned problems will be described.

[0154] 1.Mixture injection system

[0155] Before describing the hybrid module, reference will be made to Figure 1 and 2 Aspects of a mixture injection system and use of a mixing module in the mixture injection system are first described.

[0156] Figure 1 is a view showing a mixture injection system 100 according to an embodiment.

[0157] refer to Figure 1 The mixture injection system 100 may include a mixing module 1000 and a refrigerant providing device 2000 .

[0158] First, the refrigerant supply device 2000 may refer to 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 referred to as various names, such as a refrigerant spraying device, a spraying device, and the like.

[0159] The refrigerant providing device 2000 may be configured to store refrigerant therein, or to supply refrigerant thereto from a separate refrigerant storage device. For example, as described below, the refrigerant providing device 2000 is coupled to a box in which refrigerant is stored, and refrigerant may be obtained from the box coupled thereto. As another example, the refrigerant providing device 2000 may be supplied with refrigerant from an external refrigerant reservoir via a hose.

[0160] The refrigerant supply device 2000 may determine the characteristics of the supplied refrigerant. For example, the refrigerant supply device 2000 may control the supply amount, supply time, temperature and / or pressure of the refrigerant.

[0161] The mixing module 1000 may be supplied with refrigerant by the refrigerant supply device 2000 .

[0162] The mixing module 1000 may store the composition therein. For example, the mixing module 1000 may include a container storing the composition therein as described below. In addition, the mixing module 1000 may be supplied with the composition by an external component.

[0163] The mixing module 1000 may provide a mixing space in which the refrigerant and the composition are mixed together. A method for mixing the refrigerant and the composition will be described below.

[0164] Figure 2 is a view illustrating a process in which components of the mixture injection system 100 are coupled to each other according to one embodiment.

[0165] The mixing module 1000 may be detachable from or attached to the refrigerant providing apparatus 2000. Specifically, the mixing module 1000 may be mounted to or separated from one component of the refrigerant providing apparatus 2000.

[0166] refer to Figure 2 , the refrigerant providing device 2000 may include a body MB, a refrigerant injection unit 2100 coupled to the body MB, and a cartridge CTR, and the mixing module 1000 may be coupled to the refrigerant injection unit 2100 .

[0167] In addition, the mixture injection system 100 may further include a cover COV covering the refrigerant injection unit 2100. The cover COV may be coupled to the body MB of the refrigerant providing device 2000.

[0168] refer to Figure 2 , the refrigerant injection unit 2100 and the cover COV may be sequentially coupled to the body MB, and then the mixing module 1000 may be coupled to the refrigerant injection unit 2100. The cover COV may form a space through which the refrigerant injection unit 2100 passes. Therefore, when the cover COV is coupled to the body MB, the refrigerant injection unit 2100 may penetrate the cover COV.

[0169] The cap COV may be omitted in the mixture injection system 100. In addition, in the mixture injection system 100, the cap COV may be implemented as a part of the mixing module 1000. In addition, in the mixture injection system 100, the cap COV may be implemented as a part of the refrigerant providing device 2000.

[0170] In the above, the case where the mixture injection system 100 is divided into a plurality of components and the divided components are connected to and separated from each other has been described. As described above, since the mixing module 1000 can be separated from the refrigerant providing device 2000, the mixing module 1000 can be used once. In addition, the mixing module 1000 that has been used once or multiple times can be cleaned and reused.

[0171] Meanwhile, the refrigerant injection unit 2100 and the mixing module 1000 of the mixture injection system 100 may be implemented as a whole, wherein the refrigerant injection unit 2100 and the mixing module 1000 are physically connected to each other. In addition, the mixing module 1000 and the refrigerant providing device 2000 in the mixture injection system 100 may be implemented as a whole, wherein the mixing module 1000 and the refrigerant providing device 2000 are physically connected to each other. For example, the refrigerant injection unit 2100 may be included as a part of the mixing module 1000. As another example, the refrigerant injection unit 2100 and the mixing module 1000 may be included as a part of the refrigerant providing device 2000.

[0172] 2. Refrigerant supply device

[0173] Next, we will refer to Figure 3 The refrigerant supplying device 2000 is described.

[0174] Figure 3 is a view illustrating components of a refrigerant supplying apparatus 2000 according to one embodiment.

[0175] refer to Figure 3 The refrigerant providing device 2000 may include a refrigerant injection unit 2100, an injection portion coupling unit 2200, a temperature adjustment unit 2300, a flow adjustment unit 2400, a box coupling unit 2500, a sensor unit 2600, an input unit 2700, an output unit 2800 and a control unit 2900.

[0176] The refrigerant injection unit 2100 may include a structure for injecting refrigerant. Specifically, the refrigerant injection unit 2100 may form a flow path extending from one end to the other end, and may include a portion having a relatively narrow flow path width. The fluid passing through the refrigerant injection unit 2100 expands due to reduced pressure through the narrow portion of the flow path, and as a result, the fluid can be injected at high speed. At this time, while the fluid passes through the refrigerant injection unit 2100, adiabatic expansion of the fluid is achieved, so that the fluid has a low temperature, and the temperature of the refrigerant can be controlled to a temperature suitable for a program or process by the temperature adjustment unit 2300 to be described below.

[0177] The refrigerant injection unit 2100 may be understood as a nozzle. However, the technical idea of ​​the present specification is not limited thereto, and the refrigerant injection unit 2100 may be understood as a component including a flow path having an arbitrary tubular shape.

[0178] The refrigerant injection unit 2100 may be attached to or detached from the body MB of the refrigerant providing device 2000. For example, the refrigerant injection unit 2100 may be coupled to or separated from the body MB through the injection portion coupling unit 2200. In addition, the refrigerant injection unit 2100 may be physically coupled to the body MB of the refrigerant providing device 2000 to be integrally formed with the body MB.

[0179] As described above, the mixing module 1000 may be coupled to the refrigerant injection unit 2100. To this end, the refrigerant injection unit 2100 and the mixing module 1000 may include coupling parts or coupling members, respectively.

[0180] Meanwhile, 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, the function or effect produced by using the mixture injection system 100 may be different depending on the type of the mixing module 1000 coupled to the refrigerant injection unit 2100.

[0181] The injection portion coupling unit 2200 may be coupled to the refrigerant injection unit 2100. Meanwhile, when the refrigerant injection unit 2100 is omitted from the mixture injection system 100 or when the refrigerant injection unit 2100 becomes a part of the mixing module 1000, the mixing module 1000 may be coupled to the injection portion coupling unit 2200.

[0182] A flow path through which the refrigerant moves may be formed in the injection portion coupling unit 2200. For example, the injection portion coupling unit 2200 may include an outlet hole, and the refrigerant may move to the refrigerant injection unit 2100 coupled to the injection portion coupling unit 2200 through the outlet hole.

[0183] The temperature adjustment unit 2300 may adjust the temperature of the refrigerant. For example, the temperature adjustment unit 2300 may supply heat energy to the refrigerant so that the temperature of the refrigerant may increase, and the temperature of the refrigerant may be adjusted according to the amount of heat energy supplied from the temperature adjustment unit 2300. The refrigerant sprayed by the refrigerant spraying unit 2100 may have a relatively low temperature as described above, and at this time, the temperature of the refrigerant may be different according to the heat energy supplied from the temperature adjustment unit 2300.

[0184] The temperature adjustment unit 2300 may include a heat generator that generates heat energy and a heat transfer device that transfers the generated heat energy to a flow path in which the refrigerant moves. For example, the heat generator may include an element that utilizes a thermoelectric effect such as a Peltier effect, and may generate heat energy in response to applied power and the heat generator.

[0185] The flow regulating unit 2400 may control the movement of the refrigerant. For example, the flow regulating unit 2400 may include a valve, and the valve may be opened and closed by receiving a signal from the control unit 2900. Depending on whether the valve is open or closed, the refrigerant may move or not move. Depending on the degree of opening and closing of the valve, the degree of flow of the refrigerant may be controlled.

[0186] The cartridge coupling unit 2500 may accommodate at least a portion of the above-mentioned cartridge CTR. At this time, the cartridge CTR may be understood as a container in which a refrigerant is stored. Specifically, the cartridge CTR may store a refrigerant therein at a predetermined pressure, and based on 0 to 40° C., the predetermined pressure may be determined to be between approximately 35 bar and 100 bar. The pressure in the cartridge CTR may affect the injection amount or injection shape of the refrigerant, and may indirectly affect the injection amount of the composition.

[0187] When the cartridge CTR is coupled to the cartridge coupling unit 2500, the refrigerant stored in the cartridge CTR may move to the body MB.

[0188] The sensor unit 2600 may measure the temperature of the portion where the refrigerant is injected. For example, the sensor unit 2600 may measure the temperature of the skin surface to which the refrigerant is injected, and may provide the measurement information to the control unit 2900.

[0189] The input unit 2700 may receive an input from a user. For example, the input unit 2700 may include at least one push button switch, and may provide a thrust input signal to the control unit 2900 according to the pressure applied to the switch by the user, and the control unit 2900 may control the opening and closing of the flow regulating unit 2400 based on the thrust input signal. In addition, the input unit 2700 may include at least one rotary switch, and may provide a rotation input signal to the control unit 2900 according to the operation of the user, and the control unit 2900 may preset a target cooling temperature and a target cooling time based on the rotation input signal. Here, the target cooling temperature may refer to the temperature at the target that the user wants to cool to. Here, the target is the part (e.g., the skin surface) where the refrigerant is to be sprayed. In addition, the target cooling time may refer to the time when the spraying of the refrigerant should be maintained or the time when the skin surface temperature should be kept at the target cooling temperature.

[0190] The output unit 2800 may output an interface and various information for the user to use the refrigerant providing device 2000. For example, the output unit 2800 may include a display, and an interface for setting a target cooling temperature, a target cooling time, etc. may be output through the display, and during operation of the refrigerant providing 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 when the refrigerant is sprayed.

[0191] The control unit 2900 may control the components of the refrigerant providing device 2000. For example, the control unit 2900 may control the temperature adjustment unit 2300 to control the temperature of the refrigerant, and may control the flow adjustment unit 2400 to control the flow of the refrigerant, and may output specific information to the user through the output unit 2800.

[0192] refer to Figure 3 , the refrigerant supply device 2000 can operate as follows.

[0193] The control unit 2900 may first preset the target cooling temperature and / or the target cooling time. The control unit 2900 may provide an interface through the output unit 2800 to induce 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 according 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.

[0194] Then, 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 power-on input signal according to the user's operation through the input unit 2700 , and may spray the refrigerant based on the received power-on input signal.

[0195] While spraying the refrigerant, the control unit 2900 may obtain a temperature value of the temperature of the target to which the refrigerant is sprayed measured by the sensor unit 2600, and may control the temperature adjustment unit 2300 by comparing the obtained temperature value with a preset target cooling temperature. Here, when the obtained temperature value is lower than the target cooling temperature, the control unit 2900 increases 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 reduce the thermal energy applied to the refrigerant by the temperature adjustment unit 2300.

[0196] The refrigerant supplying device 2000 is not limited to the above-described embodiment, and any device and structure that performs the function of supplying refrigerant may be understood as the refrigerant supplying device 2000 described in the specification.

[0197] As an example, the refrigerant supplying device 2000 may control the temperature of the refrigerant in the form of continuously supplying a predetermined amount of heat energy 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.

[0198] 3. Hybrid Module

[0199] In the following, reference will be made to Figures 4 to 6 The mixing module 1000 is generally described.

[0200] Figure 4 is a view illustrating a mixing principle of a refrigerant and a composition according to an embodiment.

[0201] First, if Figure 4 As shown in (a), it can be considered that the tubular mixing space includes a refrigerant injection unit 2100 for injecting refrigerant and an inlet hole IH for introducing the composition.

[0202] The container in which the composition is stored and the 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 spraying unit 2100, but is not limited thereto.

[0203] refer to Figure 4 (b) When the refrigerant is sprayed from the refrigerant spraying unit 2100 , the spray shape of the refrigerant may be divided into a main stream MS and a branch stream SS based on the central axis of the refrigerant spraying unit 2100 .

[0204] The mainstream MS may refer to a region where the refrigerant injection is relatively strong, and the branch stream SS may refer to a region where the refrigerant injection is relatively weak.

[0205] Furthermore, the mainstream MS may be formed within a predetermined distance based on the central axis CA of the refrigerant injection unit 2100, and the branch stream SS may be formed outside the predetermined distance based on the central axis CA of the refrigerant injection unit 2100. However, the division criteria of the mainstream MS and the branch stream SS are not limited to the above criteria.

[0206] As described below, by the negative pressure generated when the refrigerant is sprayed, the composition can be introduced into the mainstream MS or the branch flow SS of the refrigerant and mixed with the refrigerant, and the mixed refrigerant and the composition can be sprayed together. However, the force applied by the refrigerant to the composition in the mainstream MS and the branch flow SS may be different.

[0207] The refrigerant sprayed from the refrigerant spraying unit 2100 may pass near the inlet hole IH. When the refrigerant passes near the inlet hole IH at a relatively fast speed, according to the Bernoulli equation, a negative pressure may be formed near the inlet hole IH. 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, an external force equal to atmospheric pressure may be continuously applied to the container storing the composition, and it is understood that when the external force becomes greater than the negative pressure, the composition moves.

[0208] The composition introduced into the inlet hole IH may collide with the refrigerant in a process of mixing the composition and the refrigerant, and thus, the composition may be divided into fine particles to be sprayed.

[0209] Figure 5 is a view showing a mixing module 1000 according to one embodiment.

[0210] Figure 6 is a cross-sectional view illustrating a state in which the mixing module 1000 is coupled to the refrigerant spraying unit 2100 according to one embodiment.

[0211] refer to Figure 5 and Figure 6 , the mixing module 1000 may include a mixing part 1100 , a composition inflow part 1200 , a composition storage part 1300 , a cap 1400 , and a fastening part 1500 .

[0212] The mixing part 1100 may provide a mixing space 1110 where the refrigerant and the composition are mixed together. Specifically, the inner surface of the mixing part 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 part 1100. Meanwhile, when the refrigerant injection unit 2100 is provided as a part of the mixing module 1000 or may be omitted, the insertion hole SH may be omitted.

[0213] The mixing module 1100 may include a mixture spray hole 1120. The mixture spray hole 1120 may be understood as a boundary where the refrigerant and the composition are sprayed from the mixing module 1000.

[0214] The composition inflow part 1200 may refer to a part into which the composition is introduced. Specifically, the composition inflow part 1200 may be used to fluidically connect the composition storage part 1300 in which the composition is stored and the mixing space of the mixing part 1100. To this end, the composition inflow part 1200 may form a tube 1210 for moving the composition and the above-mentioned inlet hole 1H.

[0215] The tube 1210 may provide a flow path through which the composition moves. The tube 1210 may fluidly connect the composition storage part 1300 and the mixing part 1100 .

[0216] The tube 1210 may have various shapes. Figure 6 , the tube 1210 may be implemented in a form including a bent portion. More specifically, the tube 1210 may have a form bent in a distal direction. Here, the distal direction may be understood as a direction in which the refrigerant is sprayed or a direction pointing from the first end 1100a of the mixing section 1100 to the second end 1100b. In addition, one end of the tube 1210 located in the composition storage section 1300 may be located in a portion separated in the above-mentioned distal direction based on the central axis of the composition storage section 1300. When considering the use aspect of the mixture injection system 100, the form of the tube 1210 results in the effect of using as much of the composition stored in the composition storage section 1300 as possible. For example, when using Figure 2 When the mixture injection system 100 shown is used to inject the refrigerant and the composition, the injection direction is generally directed from the upper side (the direction opposite to gravity) to the lower side (the direction of gravity), and in this case, the composition in the composition storage portion 1300 can move in the distal direction (or forward) due to gravity. Therefore, in order to use the composition in the composition storage portion 1300 as much as possible, one end of the tube 1210 needs to be located at the position where the composition moves to, that is, the front space based on the central axis of the composition storage portion 1300.

[0217] The inlet hole IH may be formed in the inner surface of the mixing part 1100. The inlet hole IH may have a cross section parallel to the central axis of the mixing part 1100 on the inner surface of the mixing part 1100.

[0218] The tube 1210 and the inlet hole IH may be understood as a whole. For example, a portion 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.

[0219] In addition, the tube 1210 and the inlet hole IH may be provided as separate components, and the tube 1210 may be implemented in a form of being coupled to the inlet hole IH.

[0220] Meanwhile, the direction in which the composition flows into the mixing part 1100 may be determined according to the position of the inlet hole 1H. Figure 6 As shown, when the inlet hole IH is located at the lower part of the inner side of the mixing section 1100, the inflow direction of the composition can be closer to the opposite direction of gravity than the gravity direction. For another example, when the inlet hole IH is located at the upper part of the inner side of the mixing section 1100, the inflow direction of the composition can be closer to the gravity direction than the opposite direction of gravity. Hereinafter, the case where the inlet hole IH is located at the lower part of the inner side of the mixing section 1100 will be described, but the technical idea of ​​the present disclosure is not limited thereto. Even when the inlet hole IH is located at the upper part of the inner side of the mixing section 1100, the following description can also be similarly applied.

[0221] The composition storage part 1300 may provide a space for accommodating the composition. The composition storage part 1300 may provide a space for storing the composition supplied from an external space.

[0222] The composition stored in the composition storage part 1300 may move to the mixing part 1100 through the composition inflow part 1200 .

[0223] Meanwhile, the composition may be continuously supplied from an external space to the mixture spraying system 100 , and the composition storage part 1300 may be understood as a component that provides a residence space for the continuously supplied composition before being introduced into the mixing part 1100 .

[0224] The cap 1400 may be a component that seals the composition storage portion 1300. Here, the composition may be stored in the composition storage portion 1300 by the following method. The user may open the cap 1400 coupled to the composition storage portion 1300, and place the composition contained in a separate composition container (e.g., an ampoule, a cosmetic container, etc.) into the composition storage portion 1300, and then close the cap 1400.

[0225] The fastening part 1500 may be fastened to the refrigerant injection unit 2100. The fastening part 1500 may include a support 1510 and an insertion hole SH. The refrigerant injection unit 2100 may be inserted into the insertion hole SH. The support 1510 may support the refrigerant injection unit 2100 inserted into the insertion hole SH. The fastening part 1500 and the refrigerant injection unit 2100 may respectively include members fastened to each other. The process of fastening the fastening part 1500 and the refrigerant injection unit 2100 to each other will be described below.

[0226] refer to Figure 5 , the mixing module 1000 may include an external air passage AP and a handle.

[0227] The external air passage AP may be fluidically connected to the composition storage portion 1300. The external air passage AP may allow the pressure in the composition storage portion 1300 to be maintained at atmospheric pressure. Therefore, when negative pressure is generated in the inlet hole 1H, the pressure in the composition storage portion 1300 is further increased, so that the composition may move to the mixing portion 1100 through the composition inflow portion 1200.

[0228] The handle may be a component that can easily separate the mixing module 1000 from the refrigerant providing device 2000 .

[0229] The above-mentioned components of the hybrid module 1000 may be manufactured independently and assembled with each other.

[0230] In addition, at least a portion of the above-mentioned components of the mixing module 1000 may be formed integrally. For example, the mixing section 1100, the composition storage section 1300, and the fastening section 1500 may be manufactured as a whole that is physically connected to each other, and the tube 1210 and the cap 1400 that can be manufactured separately may be assembled thereto. As another example, the mixing section 1100, the composition storage section 1300, and the tube 1210 may be manufactured as a whole that is physically connected to each other, and the cap 1400 may be manufactured as a separate object and may be assembled thereto.

[0231] Meanwhile, the mixing module 1000 can be implemented in a manner different from that described above. For example, the mixing module 1000 can include the above-mentioned components, and can include a container mounting portion to replace the composition storage portion 1300. The container mounting portion is configured so that the composition container is coupled thereto, and can have a structure including a needle that can pierce the stopper of the composition container or other structures that can be coupled to the composition container. The container mounting portion can be fluidically connected to the pipe 1210 or the inlet hole 1H.

[0232] In this case, the user may use the mixture spraying system 100 in a form in which the composition container itself is coupled to the mixing module 1000 , rather than putting the composition into the composition storage portion 1300 of the mixing module 1000 .

[0233] Below, for the convenience of description, this specification mainly describes the situation in which the mixing module 1000 includes a mixing part 1100, a composition inflow part 1200, a composition storage part 1300, a cap 1400 and a fastening part 1500, and the composition is transferred from a separate composition container to the composition storage part 1300, but the technical idea of ​​this specification is not limited to this.

[0234] Meanwhile, when using the above-mentioned mixing module 1000, various problems may occur depending on the properties of the composition (e.g., viscosity, cohesion, freezing point, adhesion, etc.). Hereinafter, various problems and solutions that may occur in the mixing module 1000 (e.g., design direction of the mixing module 1000) will be described in detail.

[0235] 4. Hybrid module design

[0236] Below, reference Figure 7 , basic considerations and possible problems in the design of the hybrid module 1000 will be described.

[0237] Figure 7 is a view showing an aspect of injecting a refrigerant in a mixing module 1000 according to one embodiment.

[0238] The mixing module 1000 is intended to move the composition by using refrigerant injection without a separate pressure device, and to do this, the mixing module uses negative pressure according to the above-mentioned Bernoulli equation.

[0239] refer to Figure 7 When the refrigerant is injected, a jet flow of the refrigerant may be generated in the mixing part 1100 of the mixing module 1000. In order to move the composition from the composition storage part 1300 to the mixing space 1110, a negative pressure should be generated in the inlet hole IH.

[0240] In order to generate negative pressure in the inlet hole IH, the jet flow may pass near the inlet hole IH. Here, whether the jet flow passes near the inlet hole IH depends on the size of the jet flow, the width of the mixing part 1100, and the distance between the refrigerant injection hole 2110 and the inlet hole IH.

[0241] First, the size of the jet flow may refer to a cross-sectional size of the jet flow, and specifically, may refer to a size of a cross section in the branch flow SS that is perpendicular to the central axis CA of the refrigerant injection unit 2100. The cross-sectional size of the jet flow may increase as it moves away from the refrigerant injection hole 2110. In addition, the cross-sectional size of the jet flow may increase as the injection angle in the refrigerant injection hole 2110 increases.

[0242] When the cross-sectional size of the jet corresponds to the width of the mixing portion 1100, a portion of the jet may be understood to be close to or in contact with the inner surface of the mixing portion 1100. In other words, based on the direction of spraying the refrigerant, from a critical position at a predetermined distance away from the refrigerant spraying hole 2110, the jet may be close to the inner surface of the mixing portion 1100 or may be in contact with the inner surface thereof.

[0243] In order to generate a negative pressure on the inlet hole IH formed on the inner surface of the mixing section 1100 by the jet flow, the position of the inlet hole IH should be determined based on the above-mentioned critical position. For example, the inlet hole IH can be formed at the critical position. As another example, the inlet hole IH can be formed within a predetermined distance in the distal direction (the injection direction of the refrigerant) based on the critical position. As another example, the inlet hole IH can be formed within a predetermined distance in the proximal direction (the direction opposite to the injection direction of the refrigerant) based on the critical position.

[0244] Meanwhile, the size of the jet flow near the refrigerant injection hole 2110 is relatively small compared to the width of the mixing portion 1100, so that the jet flow is not generated in the inner surface of the mixing portion 1100. Therefore, the inlet hole IH needs to be formed to be spaced apart from the refrigerant injection hole 2110 by a predetermined distance in the distal direction (the injection direction of the refrigerant).

[0245] 4.1. Possible Problem #1 and Solution

[0246] Meanwhile, as described above, the jet flow may be divided into the mainstream MS and the branch flow SS, and the jet speed of the refrigerant may be different in the mainstream MS and the branch flow SS. Specifically, the moving speed of the refrigerant in the mainstream MS may be greater than that in the branch flow SS.

[0247] Since the refrigerant in each area moves at a different speed, there may be a pressure difference between some areas inside the mixing unit 1100. For example, see Figure 7 , a relatively low air pressure may be generated around the refrigerant injection holes 2110 in the mixing part 1100 where the refrigerant moves relatively fast.

[0248] More specifically, when the refrigerant is injected, a first gas pressure may be generated at a first low pressure point P1 near the inlet hole IH, and a second gas pressure may be generated at a second low pressure point P2 near the refrigerant injection hole 2110 according to the Bernoulli equation.

[0249] Here, since the moving speed of the refrigerant near the inlet hole IH is faster than the moving speed of the refrigerant at the refrigerant injection 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 may receive a force and move to the second low pressure point P2, forming a second air pressure lower than the first air pressure at the second low pressure point P2.

[0250] Meanwhile, the force applied to the jet flow of the composition introduced through the inlet hole IH may be different depending on the region. For example, the force applied by the refrigerant to the composition in the branch flow SS may be smaller than the force applied by the refrigerant to the composition in the mainstream MS. In addition, as a force affecting the movement of the composition in the branch flow SS, the external force generated by the difference between the first gas pressure and the second gas pressure may be greater than the force generated by the refrigerant.

[0251] Therefore, for this reason, in order to inject the composition introduced into the mixing part 1100 together with the refrigerant, it is preferable to move the composition to the mainstream MS of the refrigerant. In addition, the composition that has not moved to the mainstream MS may be moved in the opposite direction to the refrigerant injection direction by the gas pressure difference, or may be moved to the second gas pressure point P2, instead of being injected through the branch stream SS.

[0252] The composition moving near the second air pressure point P2 or the refrigerant injection hole 2110 can be condensed with each other according to its properties. The condensed composition can be injected with a relatively large volume by the refrigerant, so the composition with different particle sizes can be injected from the mixing module 1000. The problem caused by such uneven composition injection is that the composition has a poor penetration effect on the target and the recipient (or subject to be treated) feels uncomfortable.

[0253] In order to solve the above problems, a structure or device is required to guide the composition to the mainstream MS. In addition, a structure or device can be used to prevent the composition from moving to the second low pressure point P2.

[0254] Next, we will refer to Figure 8 and 9 The structure of the mixing module 1000 for solving the above-mentioned problems is described.

[0255] Figure 8 is a view showing a hybrid module 1000 including a block member BM according to one embodiment.

[0256] refer to Figure 8 , a block member BM may be formed in an inner surface of the mixing part 1100 of the mixing module 1000. The block member BM may prevent the composition from moving to the refrigerant injection hole 2110 or the second end 1100b of the mixing part 1100.

[0257] The block member BM may include a block surface BS.

[0258] The block surface BS may be in contact with a portion of the composition inflow part 1200. For example, the block surface BS may be in contact with the inlet hole IH or may extend from the inlet hole IH.

[0259] The composition introduced through the inlet hole IH may move on the block surface BS of the block member BM to reach the main flow MS of the refrigerant. Therefore, the composition may not move to the second low pressure point P2 near the refrigerant injection hole 2110.

[0260] The block surface BS may have a preset block angle relative to the inlet hole IH. For example, the block surface BS may have a preset first angle relative to an imaginary plane of a cross section including the inlet hole IH. Here, the preset block angle may be determined between 0° and 90°. The block surface BS may be a plane, a curved surface, or a combination thereof.

[0261] The block member BM may have a preset block height BH. The block height BH may refer to a height of the block member BM based on the inlet hole IH in a direction perpendicular to the central axis of the mixing part 1100.

[0262] The block height BM may be preset as the height of the refrigerant mainstream MS. For example, when the width of the mainstream MS is half the width of the mixing portion 1100 , the block height may be determined to be lower than half the width of the mixing portion 1100 .

[0263] The block member BM may be integrally formed with the mixing part 1100. Specifically, the block member BM may be shaped to protrude from the inner surface of the mixing part 1100.

[0264] The block member BM may be coupled to the inner surface of the mixing part 1100 while being formed separately from the mixing part 1100 .

[0265] At the same time, when the block member BM is used to prevent the condensation of the composition, the composition used for mixing and spraying needs to have a relatively low adhesion. Here, the adhesion can be understood as the pulling force between the block member BM and the composition. Therefore, when a composition with high adhesion is used, the composition rises above the block surface BS of the block member BM, and as a result, the effect of condensation of the composition at the second low pressure point P2 may occur.

[0266] In addition, when using the block BM, the composition used for mixing and spraying needs to have a relatively high freezing point. This is because the temperature of the block BM may be lowered by the sprayed refrigerant, and thus the temperature of the composition moving on the block BM is also lowered, resulting in the problem that the composition is sprayed in a frozen state.

[0267] Fig. 9 1 is a view showing a hybrid module 1000 including an inclined member IM according to one embodiment.

[0268] The region where the composition is condensed in the mixing part 1100 of the mixing module 1000 may be filled. Fig. 9 , the hybrid module 1000 may include an inclined member IM.

[0269] The inclined member IM may be understood as a block having an inclination, a ramp, or a slope. The inclined member IM may be disposed between the inlet hole IH and the refrigerant injection hole 2110.

[0270] The inclined member IM may include an inclined surface INS. The inclined surface INS may be implemented with a plane, a curved surface, or a combination thereof.

[0271] The inclined surface INS may contact a portion of the composition inflow part 1200. For example, the inclined surface INS may contact the inlet hole IH or may extend from the inlet hole IH.

[0272] The inclined surface INS may extend from the composition inflow portion 1200 to the vicinity of the refrigerant injection hole 2110. For example, the inclined surface INS may contact the refrigerant injection hole 2110.

[0273] The inclined surface INS may be designed in consideration of the injection shape of the refrigerant. For example, the inclined surface INS may be designed to correspond to the shape of the mainstream MS.

[0274] In addition, the inclined surface INS may be implemented in the form of an inclination having a predetermined angle.

[0275] The inclined member IM may be formed integrally with the mixing part 1100. Specifically, the inclined member IM may be understood as a portion having an inclination among a portion of the inner surface of the mixing part 1100.

[0276] The block member BM may be coupled to the inner surface of the mixing part 1100 while being produced separately from the mixing part 1100. Specifically, the inclined member IM may be provided on the inner surface of the mixing part 1100 in the shape of an inclined block or an inclined plate.

[0277] The composition introduced into the inlet hole IH may rise on the inclined surface INS of the inclined member IM, and may be ejected by the main flow MS of the refrigerant during the rising. As a result, the composition may be ejected by the refrigerant before condensation.

[0278] Meanwhile, when using the tilting member 14, the composition for spraying needs to have a relatively high freezing point. This is because the temperature of the tilting member 14 may be lowered by the sprayed refrigerant, and thus the temperature of the composition moving on the tilting member 14 is also lowered, resulting in the problem of frozen composition being sprayed.

[0279] 4.2. Possible Problem #2 and Solutions

[0280] As described above, when the mixing module 1000 is designed so that the composition reaches the main flow MS of the refrigerant, condensation of the composition may be prevented, but a phenomenon in which the composition is not uniformly mixed with the refrigerant may occur.

[0281] Specifically, when the block member BM is Fig.10 When used in the mixing module 1000 , as shown in a mixing section cross section 1100 s perpendicular to the central axis of the mixing section 1100 , the composition may be sprayed obliquely to a portion (eg, a lower portion) of the main flow MS of the refrigerant.

[0282] If the goal is to evenly disperse and spray the composition throughout the mainstream MS rather than spraying the composition more concentratedly in one area, it is necessary to prevent the above phenomenon from occurring.

[0283] In order to solve the above problem, it is necessary to guide the composition to move to the upper part of the main flow MS of the refrigerant in addition to reaching the lower part of the main flow MS.

[0284] To this end, the mixing module 1000 may include a guide member. The guide member provides a surface on which the composition moves, and the shape of the surface may enable the composition to move to an upper portion of the main flow MS.

[0285] Specifically, the guide member may be implemented in a form that surrounds at least a portion of the refrigerant. For example, the guide member may be implemented in a form that surrounds at least a portion of the mainstream MS. In this case, the guide member may avoid interfering with the injection of the refrigerant and may allow the composition to diffuse to the upper portion of the mainstream MS.

[0286] Next, we will refer to Figures 11 to 19 Various embodiments of the guide member are described. Meanwhile, it is disclosed in advance that the guide member may be variously referred to as a guide plate, a spreading film, a metal film, a spreading plate, a heat exchange inducing member, a heat transfer member, an insert, etc. according to its form or function.

[0287] Fig.11 is a view showing a guide plate 1610 according to one embodiment.

[0288] Fig.12 16 is a view illustrating a process in which a composition moves through a guide plate 1610 according to one embodiment.

[0289] Fig.13 1 is a view illustrating a form of a guide plate 1610 based on a mixing part 1100 and a first plate 1611 of the guide plate 1610 according to one embodiment.

[0290] The guide plate 1610 may be provided in the mixing section 1100 of the mixing module 1000 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 idea of ​​the present specification is not limited to the above description, and the guide plate 1610 may be implemented in a state of being physically integrated with the mixing section 1100.

[0291] The guide plate 1610 can be understood as a structure composed of multiple surfaces. Fig.11 , the guide plate 1610 may include a first plate 1611 and a second plate 1612. Here, the expression of the first plate 1611 and the second plate 1612 is a term used to refer to components of the guide plate 1610, and may be expressed as first and second parts, first and second frames, first and second structures, etc.

[0292] The first plate 1611 may include at least a first plate surface S11 and a second plate surface S12 .

[0293] Here, the first plate surface S11 may refer to a surface that contacts the inner surface of the mixing part 1100 when the first plate 1611 is disposed in the mixing part 1100. Specifically, the first plate 1611 is disposed near the inlet hole 1H, such as Fig.11As shown, and here, the first plate surface S11 may be in contact with the inner surface of the mixing part 1100. The first plate surface S11 and the inner surface of the mixing part 1100 may be in surface contact or line contact with each other.

[0294] The second plate surface S12 may refer to a surface that is inclined at a preset angle relative 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 relative to a flat surface including the inlet hole IH. Here, a specific angle may be provided between the first plate surface S11 and the second plate surface S12. The composition introduced through the inlet hole IH may move on the second plate surface S12 by adhering to the second plate surface S12.

[0295] The first plate surface S11 and the second plate surface S12 may be shaped as a flat surface, a curved surface, or a combination thereof.

[0296] The first plate surface S11 and the second plate surface S12 may be directly or indirectly connected to each other.

[0297] 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.

[0298] The first plate surface S11 and the second plate surface S12 may not intersect each other, and in this case, the additional surface may be located between the first plate surface S11 and the second plate surface S12. Here, the flat surface including the first plate surface S11 and the flat surface including the second plate surface S12 may intersect each other or may be parallel to each other.

[0299] The first plate 1611 may further include an additional surface in addition to the above-described first plate surface S11 and second plate surface S12 .

[0300] The first plate 1611 may be implemented in various forms. As an example, the first plate 1611 may be implemented in a form of being bent or folded at a predetermined angle, such as Fig.11 As another example, the first plate 1611 may be implemented in various forms, such as a rectangular parallelepiped form, a form having a curved surface, and the like.

[0301] The second plate 1612 may include at least a third plate surface S13 and a fourth plate surface S14.

[0302] Here, the third plate surface S13 may refer to a surface that contacts the inner surface of the mixing unit 1100 when the second plate 1612 is disposed in the mixing unit 1100. Specifically, the second plate 1612 is disposed near the inlet hole 1H, such as Fig.11As shown, and here, the third plate surface S13 may be in contact with 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 surface contact or line contact with each other.

[0303] The fourth plate surface S14 may refer to a surface that is inclined at a preset angle relative to the inlet hole IH when the second plate 1612 is disposed in the mixing section 1100. In other words, the fourth plate surface S14 may have a preset angle relative to a flat surface including the inlet hole IH. Here, a specific angle may be provided between the third plate surface S13 and the fourth plate surface S14. The composition introduced through the inlet hole IH may move on the fourth plate surface S14 by adhering to the fourth plate surface S14.

[0304] The third plate surface S13 and the fourth plate surface S14 may be shaped as a flat surface, a curved surface, or a combination thereof.

[0305] The third plate surface S13 and the fourth plate surface S14 may be directly or indirectly connected to each other.

[0306] The third plate surface S13 and the fourth plate surface S14 may intersect each other. In other words, the third plate surface S13 and the fourth plate surface S14 may contact each other or may share one edge.

[0307] The third plate surface S13 and the fourth plate surface S14 may not intersect each other, and in this case, an additional surface may be provided between the third plate surface S13 and the fourth plate surface S14. Here, the flat surface including the third plate surface S13 and the flat surface including the fourth plate surface S14 may intersect each other or may be parallel to each other.

[0308] In addition to the third plate surface S13 and the fourth plate surface S14 described above, the second plate 1612 may further include an additional surface.

[0309] The second plate 1612 may be implemented in various forms. For example, the second plate 1612 may be implemented in a form of being bent or folded at a predetermined angle, such as Fig.11 As another example, the second plate 1612 may be implemented in various forms, such as a rectangular parallelepiped form, a form having a curved surface, and the like.

[0310] The first plate 1611 and the second plate 1612 may be disposed to have a specific positional relationship in the mixing unit 1100. As an example, refer to Fig.11 (a) or Fig.12 , the first plate 1611 and the second plate 1612 may be disposed to be spaced apart from each other. Here, the inlet hole IH may be located between the first plate 1611 and the second plate 1612.

[0311] The first plate 1611 and the second plate 1612 may be disposed symmetrically to each other in the mixing part 1100 .

[0312] Meanwhile, the guide plate 1610 may include only one of the first plate 1611 and the second plate 1612 .

[0313] refer to Fig.13 , the composition introduced through the inlet hole IH may move on the guide plate 1610. The composition moving on the guide plate 1610 may be mixed with the mainstream MS of the refrigerant to be sprayed together. As described below, when the height of the guide plate 1610 is high enough, the composition may reach the upper part of the mainstream MS. Therefore, the composition is mixed with the refrigerant not only at the lower part but also at the upper part of the mainstream MS, and as a result, the composition may be uniformly distributed throughout the mainstream MS.

[0314] As described above, in order to allow the composition to move on the guide plate 1610 to reach the upper portion of the mainstream MS, the guide plate 1610 needs to be designed to have a specific size.

[0315] refer to Fig.13 (a), the guide plate 1610 may be designed to have a predetermined height, a predetermined distance, and a predetermined tilt angle.

[0316] The height of the guide plate 1610 may refer to a height when the guide plate 1610 is disposed in the mixing unit 1100. As an example, the first plate 1611 may have a first height H1 based on the inlet hole IH in a direction perpendicular to the central axis of the mixing unit 1100. The second plate 1612 may have a second height H2 based on the inlet hole IH in a direction perpendicular to the central axis of the mixing unit 1100.

[0317] The distance of the guide plate 1610 may refer to the distance from the central portion 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. Here, the first distance D1 may 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.

[0318] The inclination angle of the guide plate 1610 may refer to an angle relative to the inlet hole IH when the guide plate 1610 is disposed in the mixing part 1100. As an example, the second plate surface S12 of the first plate 1611 may have a first inclination angle IA1 based on a surface including the inlet hole IH or a surface parallel to the inlet hole IH. In addition, the second plate 1612 may also have a second inclination angle IA2.

[0319] refer to Fig.13(b), the guide plate 1610 may be designed to have a predetermined length.

[0320] The length of the guide plate 1610 may be defined in a direction parallel to the central axis of the mixing unit 1100. Fig.13 As shown in (b), the first plate 1611 extends from the first plate end 1611a to the second plate end 1611b and has a first length L1. Here, the first length L1 can be understood as the length of a straight line connecting a point of the first plate end 1611a and a point of the second plate end 1611b in a straight line parallel to the central axis of the mixing section 1100. The second plate 1612 can also extend from the third plate end to the fourth plate end and can have a second length.

[0321] The height and distance of the guide plate 1610 may be designed based on the internal structure of the mixing part 1100. However, the mixing part 1100 may have a third height H3 based on the inlet hole IH and assume a preset width W. The central axis of the mixing part 1100 is assumed to be equal to the central axis CA of the refrigerant spraying unit 2100.

[0322] The height of the guide plate 1610 may preferably be designed to be equal to or higher than half the height of the mixing portion 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 the third height H3 of the mixing portion 1100. As described above, this is to allow the composition to reach the upper portion of the refrigerant mainstream MS.

[0323] The distance of the guide plate 1610 is preferably designed to be equal to or greater than 1 / 4 of the width W of the mixing portion. 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 greater than 1 / 4 of the width W of the mixing portion. This is because the width of the guide plate 1610 is designed based on 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 refrigerant mainstream MS, the refrigerant injection is deteriorated, and in addition, the temperature of the refrigerant in the guide plate 1610 is reduced and the composition is frozen.

[0324] 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 relative 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 an additional surface needs to be provided between the first plate surface S11 and the second plate surface S12. The second inclination angle IA2 of the second plate 1612 may also be described as described in the first inclination angle IA1.

[0325] The length of the guide plate 1610 may be shorter than the length of the inner surface of the mixing part 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 part 1100. Considering the diffusion degree of the composition introduced through the inlet hole IH, the length of the guide plate 1610 may be equal to or greater than a predetermined value.

[0326] Meanwhile, when using the guide plate 1610, the composition for spraying needs to have a relatively high freezing point. This is because the temperature of the guide plate 1610 may be lowered by the sprayed refrigerant, and thus the temperature of the composition moving on the guide plate 1610 is also lowered, resulting in problems in spraying the frozen composition.

[0327] Fig.14 is a view showing a spreading film 1620 according to one embodiment.

[0328] refer to Fig.14 , the spreading film 1620 may extend from a first film end 1620a to a second film end 1620b and may include an inner surface IS and an outer surface OS.

[0329] The spreading film 1620 may be attached to and detached from the mixing part 1100 of the mixing module 1000. In addition, the spreading film 1620 may be implemented to be integrated with the mixing part 1100 so that the spreading film 1620 may constitute a part of the mixing part 1100.

[0330] The spreading film 1620 may be manufactured with a curved or arc-shaped plate, but the present specification is not limited thereto.

[0331] The outer surface OS of the spreading film 1620 may include a contact portion, which may refer to a portion of the spreading film 1620 that contacts the inner surface of the mixing part 1100 when the spreading film 1620 is mounted to the mixing part 1100 .

[0332] The contact portion of the spreading film 1620 may include 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 spreading film 1620 is disposed close to the inlet hole IH, the first film surface S21 may be in contact with the inner surface of the mixing section 1100. The first film surface S21 and the inner surface of the mixing section 1100 may be in surface contact or line contact with each other.

[0333] The inner surface IS of the spreading film 1620 may include an inclined portion. The inclined portion may refer to a portion on which the composition moves. The outer surface OS and the inner surface IS of the spreading film 1620 may face each other.

[0334] The inclined portion of the spreading film 1620 may include a second film surface S22. The second film surface S22 is a surface that is inclined at a preset angle relative to the inlet hole IH when the spreading film 1620 is disposed at the mixing section 1100, and can be understood as a surface that guides the movement of the composition. In other words, the second film surface S22 may have a preset angle relative to the flat surface including the inlet hole IH. Here, a specific angle may be provided between the first film surface S21 and the second film surface S22.

[0335] The first film surface S21 and the second film surface S22 may be directly or indirectly connected to each other.

[0336] 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 folded over each other and may share one edge.

[0337] The first film surface S21 and the second film surface S22 do not intersect each other, and in this case, there may be an additional surface between the first film surface S21 and the second film surface S22. Here, the flat surface including the first film surface S21 and the flat surface 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.

[0338] The spreading film 1620 may include 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 symmetrical to each other based on the central axis of the spreading film 1620, and the second film surface and the fourth film surface may be symmetrical to each other based on the central axis of the spreading film 1620.

[0339] The composition introduced through the inlet hole IH may move on the inner surface IS by adhering to the inner surface IS.

[0340] The outer surface OS of the spreading film 1620 may consist of one curved surface, multiple flat surfaces, multiple curved surfaces, or a combination thereof. Similarly, the inner surface IS of the spreading film 1620 may consist of one curved surface, multiple flat surfaces, multiple curved surfaces, or a combination thereof.

[0341] Fig.15 is a view showing a front surface of a spreading film 1620 according to one embodiment.

[0342] refer to Fig.15, the spreading film 1620 may include a first portion 1621, a second portion 1622, and a third portion 1623. For ease of description, each of the first to third portions 1621, 1622, and 1623 is an expression for referring to a portion of the spreading film 1620, and may be referred to as first to third plates, first to third frames, first to third structures, etc.

[0343] The first portion 1621 and the second portion 1622 may be understood to correspond to the first plate 1611 and the second plate 1612 of the guide plate 1610, respectively. Specifically, the first portion 1621 and the second portion 1622 may be positioned so that the inlet hole IH is located therebetween, and the composition introduced through the inlet hole IH may move to the mainstream MS of the refrigerant while leaning on the first portion 1621 or the second portion 1622.

[0344] Unlike the guide plate 1610, the spreading film 1620 may include a third portion 1623 connecting the first portion 1621 and the second portion 1622 to each other. In other words, the first to third portions 1621, 1622, and 1623 may be formed as one physical entity.

[0345] The third portion 1623 may have an arch 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.

[0346] As described below, the third portion 1623 can facilitate more uniform mixing of the composition into the spray stream of refrigerant.

[0347] Fig.16 16 is a view showing a process in which a composition moves through a spreading film 1620 according to one embodiment.

[0348] refer to Fig.16 , the composition introduced through the inlet hole IH may move on the first part 1621 to reach the third part 1623 , or may move on the second part 1622 to reach the third part 1623 .

[0349] The composition may be moved in the order of first part 1621-third part 1623-second part 1622 or in the order of second part 1622-third part 1623-first part 1621 to rotate based on the central axis of spreading film 1620. The rotation of the composition may allow the composition to be uniformly distributed in the spray flow of the refrigerant.

[0350] Furthermore, the third portion 1623 may prevent the composition from moving out of the main flow MS of the refrigerant.

[0351] The spreading film 1620 may be manufactured by bending a flat plate as described above. As an example, the spreading film 1620 may be manufactured by the steps of preparing a square plate having a first side and a second side facing each other and bending the square plate so that the first side and the second side face each other. Here, the first side and the second side may constitute the outer surface OS and may be included in the contact portion.

[0352] Meanwhile, when the spreading film 1620 is manufactured as described above, Fig.14 As shown, a gap may be formed between first portion 1621 and second portion 1622 of spreading film 1620. When spreading film 1620 is manufactured in a form of injection metal or the like in a specific shape, first portion 1621 and second portion 1622 may be directly connected to each other and may not form a gap therebetween.

[0353] Again Fig.14 As shown, the spreading film 1620 may include an inlet groove and a fastening groove CG.

[0354] 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 .

[0355] The spreading film 1620 may be fastened to the inner portion of the mixing part 1100 through the fastening groove CG. A connecting member (eg, a hook member) may be formed in the mixing part 1100 to correspond to the fastening groove CG. The fastening groove CG may be formed in the third portion 1623 of the spreading film 1620, but is not limited thereto.

[0356] The spreading film 1620 may have a preset radius of curvature.

[0357] Fig.17 is a view showing a curvature radius CR of a spreading film 1620 according to one embodiment. Fig.17 , a portion of the inner surface IS of the spreading film 1620 may have a curvature radius CR. The curvature radius CR may be understood as the curvature radius CR of a portion of the inner surface IS of the spreading film 1620 corresponding to the third portion 1623 .

[0358] The radius of curvature CR may be designed to be smaller than the width W of the mixing section and equal to or greater than 1 / 4 of the width W. However, when the cross section of the mixing section 1100 is not circular but elliptical, the mixing section 1100 may be designed differently and the mixing section 1100 may be experimentally determined to correspond to the maximum size of the cross section of the mainstream MS of the refrigerant.

[0359] As an example, for the mixing section 1100 providing a mixing space having a specific form, an experiment is conducted to observe the spot size of the refrigerant sprayed from the mixing module 1000 and whether the composition is frozen when the curvature radius CR is changed, and the optimal value of the curvature radius CR can be determined through experiments.

[0360] The spreading film 1620 may have a film width FW. The film width FW may be understood as the horizontal maximum width of the spreading film 1620. As an example, the film width FW may be twice the curvature radius CR.

[0361] Meanwhile, the spreading film 1620 may have a predetermined length, and the length of the spreading film 1620 may be understood to be equal to the first length L1 of the guide plate 1610 described above.

[0362] Fig.18 is a view showing a spreading film 1620 according to one embodiment.

[0363] The spreading film 1620 may be implemented such that its cross section has a keyhole shape. Fig.18 As shown, the first portion 1621 of the spreading film 1620 may include a first film surface S21 in contact with the inlet hole IH and a second film surface S22 having a cross section substantially perpendicular to the inlet hole IH. Similarly, the second portion 1622 of the spreading film 1620 may include a third film surface S23 in contact with the inlet hole IH and a fourth film surface S24 having a cross section substantially perpendicular to the inlet hole IH.

[0364] In addition, the spreading film 1620 may have various forms. As an example, the spreading film 1620 may have a form in which its width narrows or widens in a direction from the first film end 1620a to the second film end 1620b. In addition, the cross-sectional shape of the spreading film 1620 may be implemented differently, such as a circular shape, an elliptical shape, a polygonal shape, or a figure composed of a combination of straight lines and curves.

[0365] Fig.19 are views showing various shapes of a guide member according to an embodiment.

[0366] refer to Fig.19 (a), the guide wall 1630 may protrude from the inner surface of the mixing part 1100. Specifically, the guide wall 1630 may be formed on both sides with the inlet hole IH inserted therebetween, and the surface of the guide wall 1630 may be designed to be equal to the second plate surface S12 of the above-mentioned first plate 1611 and the fourth plate surface S14 of the second plate 1612. Here, 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 part 1100 based on the inlet hole IH.

[0367] refer 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 so that there is no gap between the first plate 1611 and the second plate 1611. The third plate 1613 may have a hole corresponding to the inlet hole IH. Since the guide plate 1610 also 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, the advantage is that the composition can move to the mainstream MS of the refrigerant not only laterally but also in all directions on the guide plate 1610.

[0368] 4.3. Possible Problem #3 and Solutions

[0369] When the freezing point of the composition is relatively high, the temperature of the mainstream MS of the refrigerant is relatively low, and thus it is possible to spray the frozen composition, which has been described above.

[0370] In order to solve the problem of freezing of the composition, a method of applying heat to the mixing part 1100 to increase the temperature of the mixing part 1100 or a method of directly increasing the temperature of the composition may be considered. However, since an additional heating device is required, these methods may result in deterioration of the cooling effect of the refrigerant or a decrease in product quality or an increase in manufacturing cost.

[0371] Below, reference Figures 20 to 23 , a design direction of the mixing module 1000 will be described, which prevents the composition from freezing without inhibiting the cooling effect as much as possible and without using a separate device.

[0372] The basic principle is as follows: The inner space of the mixing part 1100 is divided into a region corresponding to the mainstream MS of the refrigerant and other regions, and the region in which the external air having a relatively higher temperature than the refrigerant is separated is continuously circulated, thereby preventing the composition from freezing.

[0373] Fig. 20 is a view showing a spreading film 1620 having ventilation holes VH according to one embodiment.

[0374] Fig.21 is a view illustrating a process of introducing external air into the mixing module 1000 to circulate according to one embodiment.

[0375] Fig. 22 is a cross-sectional view showing a mixing part 1100 installed with a spreading film 1620 according to an embodiment.

[0376] like Fig. 20 As shown, use Fig.14 The spreading film 1620 described in the specification and the vent holes VH may be formed in the spreading film 1620.

[0377] refer to Fig.21 , when the spreading film 1620 is installed to the mixing section 1100, the internal space of the mixing section 1100 can be divided into a first area A1 inside the spreading film 1620 and a second area A2 outside the spreading film 1620. Here, the first area A1 can be understood as the area where the mainstream MS of the refrigerant is located. When the refrigerant is sprayed, the pressure of the internal space of the mixing section 1100 is completely reduced, so that the air outside the mixing section 1100 can be introduced into the mixing section 1100. Here, when the refrigerant in the first area A1 is sprayed, the external air can be introduced into the second area A2 instead of the first area A1, as shown in FIG. Fig.21 (a) shown.

[0378] like Fig.21 As shown in (b), the external air introduced into the second area A2 can move to the vent holes VH formed in the spreading film 1620. This means that the closer the vent holes VH are formed to the first film end 1620a of the spreading film 1620, the more external air can move to the inner space of the mixing part 1100 or the vicinity of the refrigerant injection hole 2110.

[0379] Then, external air may be introduced into the first area A1 through the vent hole VH, and thus, the external air may be discharged from the mixing portion 1100 together with the refrigerant.

[0380] In other words, through the vent holes VH formed in the spreading film 1620, external air having a relatively higher temperature than the refrigerant can be continuously circulated to the second area A2-vent holes VH-first area A1, and the circulating external air can provide heat to the spreading film 1620 when passing through the outer surface OS of the spreading film 1620.

[0381] The spreading film 1620 may be supplied with heat by the external air, and transfer the heat to the composition moving on the spreading film 1620. When the heat is transferred to the composition, the composition may be sprayed without being frozen.

[0382] Reference again Fig. 20 , the vent hole VH may be formed near the first film end 1620a of the spreading film 1620, rather than the second film end 1620b of the spreading film 1620. In addition, the vent hole VH may be formed near the first film end 1620a of the spreading film 1620, rather than the middle point between the first film end 1620a and the second film end 1620b of the spreading film 1620. Therefore, the external air may be exhausted after moving to the internal space of the mixing part 1100, and thus the spreading film 1620 may be supplied with heat by the external air as a whole.

[0383] refer to Fig. 22, in a state where the spreading film 1620 is mounted to the mixing section 1100, the vent hole VH may be located near the first end 1100a of the mixing section 1100, rather than the second end 1100b of the mixing section 1100. In addition, the vent hole VH may be located between the inlet hole IH and the first end 1100a. In addition, the vent hole VH may be located between the inlet hole IH and the first end 1100a, and may be located near the first end 1100a, rather than the inlet hole IH.

[0384] The vent hole VH may be formed at each of the left and right portions of the spreading film 1620. In addition, the vent hole VH may be formed at one of the left or right portions of the spreading film 1620.

[0385] The vent hole VH may be implemented in various forms. As an example, the vent hole VH may have a circular form, a polygonal form, or an elliptical form.

[0386] As described above, in order to allow the spreading film 1620 to be supplied with heat by the external air and transfer the supplied heat to the composition, the thermal conductivity of the spreading film 1620 needs to be equal to or higher than a predetermined value.

[0387] In terms of thermal conductivity, experimental results using various metals show that copper (Cu), aluminum (Al) and stainless steel (SUS) do not cause the composition to freeze. Therefore, according to the example, the spreading film 1620 may be composed of copper (Cu), aluminum (Al), stainless steel (SUS) or a combination thereof. In addition, as another example, the thermal conductivity of the spreading film 1620 may be higher than that of SUS. Specifically, the spreading film 1620 may have a thermal conductivity equal to or higher than 12 W / m·K.

[0388] In addition, in order to effectively perform heat transfer of the spreading film 1620, the thickness of the spreading film 1620 also needs to be less than or equal to a predetermined value. As an example, the thickness of the spreading film 1620 can be approximately less than or equal to 1.0 mm. Preferably, the thickness of the spreading film 1620 can be less than or equal to 0.5 mm. More preferably, the thickness of the spreading film 1620 can be approximately 0.3 mm.

[0389] Meanwhile, even if the ventilation holes VH are not formed in the spreading film 1620, circulation of external air may be induced.

[0390] Fig.23 21 is a view illustrating a state in which a spreading film 1620 is disposed at the mixing part 1100 to form a gap between the spreading film 1620 and the refrigerant injection hole 2110 according to one embodiment.

[0391] refer to Fig.23, the spreading film 1620 may be disposed in the mixing portion 1100 so that a gap is formed between the first film end 1620a of the spreading film 1620 and the refrigerant injection hole 2110. For example, when the spreading film 1620 is disposed in the mixing portion 1100, the first film end 1620a of the spreading film 1620 may be spaced apart from the refrigerant injection hole 2110 by a preset distance in a distal direction (e.g., a spraying direction of the refrigerant). In addition, the first film end 1620a may be spaced apart from the first end 1100a of the mixing portion 1100 by a preset distance in the distal direction.

[0392] Meanwhile, the form of the first film end 1620 a of the spreading film 1620 may be designed to form a space between the spreading film 1620 and the first end 1100 a when the spreading film 1620 is disposed in the mixing part 1100 .

[0393] Here, the length of the spreading film 1620 may be shorter than the length of the mixing part 1100, but is not limited thereto.

[0394] A gap or space formed between the spreading film 1620 and the first end 1100 a of the mixing part 1100 or the refrigerant injection hole 2110 may function as the vent hole VH described above.

[0395] 4.4. Selective use of guidance components

[0396] As described above, the guide member may solve problems that may occur when the refrigerant and the composition are mixed and injected in the mixture injection system 100 .

[0397] The form of the guide member for solving any problem can be various, and according to the nature of the composition, a guide member with a desired form (e.g., a form installed to the mixing module 1000 or integrated with the mixing module 1000) can be used. As an example, when the viscosity and cohesion of the composition are relatively low and the freezing point is relatively low, the guide member may not be used. As another example, when the viscosity and cohesion of the composition are relatively high and the freezing point is relatively low, a guide plate 1610, a spreading film 1620, or a spreading film 1620 with a vent VH can be used. As another example, when the freezing point of the composition is relatively high, a spreading film 1620 with a vent VH can be used.

[0398] 5. Connection between mixing module and refrigerant supply device

[0399] Next, we will refer to Fig.24 and 25 The process of coupling the mixing module 1000 and the refrigerant providing device 2000 to each other and the components required therefor are described. Fig.26 An assembly for mounting a guide member to the mixing module 1000 is described.

[0400] Fig.24 is a view illustrating a process of mounting the mixing module 1000 to the refrigerant spraying unit 2100 according to one embodiment.

[0401] refer to Fig.24 , the mixing module 1000 may include a first fastening member 1520 , and the refrigerant spraying unit 2100 may include a second fastening member 2130 .

[0402] The first fastening member 1520 may be formed in the fastening part 1500 of the hybrid module 1000. The first fastening member 1520 may be a hook member. In addition, the first fastening member 1520 may include a locking protrusion.

[0403] The second fastening member 2130 may be formed in the outer surface of the refrigerant spraying unit 2100. The second fastening member 2130 may include a groove or a hole.

[0404] The first fastening member 1520 of the mixing module 1000 and the second fastening member 2130 of the refrigerant injection unit 2100 may be coupled to each other. As an example, when the refrigerant injection unit 2100 is inserted into the mixing module 1000 in a sliding manner, the locking portion of the first fastening member 1520 may be caught by the groove of the second fastening member 2130.

[0405] The refrigerant injection unit 2100 may include an O-ring 2120. The O-ring 2120 may strengthen the coupling between the refrigerant injection unit 2100 and the mixing module 1000, and may play a sealing function as described below. The O-ring 2120 may be located between the refrigerant injection hole 2110 and the second fastening member 2130. Therefore, any separation of the mixing module 1000 from the refrigerant injection unit 2100 may be prevented.

[0406] Fig.25 2 is a view illustrating a process of performing sealing when the mixing module 1000 is coupled to the refrigerant spraying unit 2100 according to one embodiment.

[0407] refer to Fig.25 , when the refrigerant injection unit 2100 is inserted into the mixing module 1000, the front portion of the refrigerant injection unit 2100 (including the portion of the refrigerant injection hole 2110) is inserted into the insertion hole SH of the support 1510, and thus, the support 1510 can support the refrigerant injection hole 2110.

[0408] Meanwhile, when the refrigerant is sprayed from the refrigerant spraying unit 2100, some of the refrigerant may flow backwards in the opposite direction to the spraying direction of the refrigerant in the mixing part 1100. The support 1510 may prevent the refrigerant flowing backwards from reaching the refrigerant spraying unit 2100.

[0409] In addition, reference Fig.25 (b) The O-ring 2120 of the refrigerant injection unit 2100 may prevent external air from being introduced into the gap between the mixing module 1000 and the refrigerant injection unit 2100 .

[0410] As described above, the support 1510 and the O-ring 2120 reduce the risk due to the backward flow of the refrigerant or the inflow of the external air to improve the stability of the fastening between the mixing module 1000 and the refrigerant spraying unit 2100 .

[0411] Fig.26 is a view showing a configuration of a guide member 1000 to be mounted to a mixing module according to an embodiment. Hereinafter, the present specification is described with the guide member being a spreading film 1620, but the technical idea of ​​the present specification is not limited thereto.

[0412] The mixing module 1000 may include at least one protrusion. As an example, refer to Fig.26 , first to fifth protrusions 1131 , 1132 , 1133 , 1134 , and 1135 may be included in the interior of the mixing part 1100 .

[0413] A protrusion may be understood as a component used to support a particular object, such as a rib or a rail.

[0414] The protrusions may support the spreading film 1620. Specifically, the protrusions may support the spreading film 1620 from shaking in the mixing section 1100. As an example, when the spreading film 1620 is mounted to the mixing module 1000, the first protrusion 1131 supports the first portion 1621 of the spreading film 1620, and the second to fourth protrusions 1132, 1133, and 1134 support the third portion 1623 of the spreading film 1620, and the fifth protrusion 1135 may support the second portion 1622 of the spreading film 1620.

[0415] The protrusions may be designed to correspond to the form of the spreading film 1620 .

[0416] The plurality of protrusions may be symmetrically formed based on the central axis of the mixing part 1100 , but is not limited thereto.

[0417] Each protrusion in the mixing part 1100 may have a certain length in a direction parallel to the central axis of the mixing part 1100. The length of the protrusion may be shorter than the length of the inside of the mixing part 1100.

[0418] 6. Mixing module design considering injection volume

[0419] As described above, in the mixture injection system 100, the composition can be moved by the negative pressure formed according to the injection of the refrigerant. As a result, the injection amount of the composition depends in part on the injection amount of the refrigerant.

[0420] In this case, if the amount of the composition or the injection amount of the composition and the amount of the refrigerant or the injection amount of the refrigerant are not accurately controlled, there may be a situation where only the refrigerant can be injected due to a lack of the composition or a situation where the required amount of the composition (for example, the amount of the composition required for one procedure or one treatment) cannot be fully injected due to a lack of the refrigerant.

[0421] In other words, when designing a device that sprays refrigerant and composition together, the "same consumption time condition" should be met, wherein the time required to consume a specific amount (e.g., ampoule capacity) of the composition and the time required to consume a specific amount (e.g., cartridge capacity) of the refrigerant are substantially the same as each other.

[0422] Fig. 27 is a view showing a mixing module 1000 according to one embodiment, in which elements affecting the spraying amount of the composition are marked.

[0423] refer 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 box CTR, the refrigerant pressure (e.g., the internal pressure of the box CTR), the size of the refrigerant injection hole 2110, the width W of the mixing section, the width of the guide member (e.g., the film width FW), the tube width TW of the tube 1210, and the properties of the composition (e.g., the viscosity of the composition).

[0424] In the following, for the convenience of description, the present specification is described with the guide member being the spreading film 1620 , but the technical concept of the present specification is not limited thereto.

[0425] Among the above-mentioned influencing factors, after the values ​​of the factors that are difficult to control are specified, the values ​​of the factors that can be controlled can be designed in consideration of the values ​​of the specified factors and the "same consumption time condition".

[0426] First, the type of composition can be specified. The type of composition can be specified according to the type of procedure or treatment to be provided. The treatment to be provided is difficult to change arbitrarily, so the type of composition is also difficult to change, and the properties of the composition, such as the viscosity of the composition, etc., can be understood as specific values.

[0427] In addition, the amount of the composition can be determined according to the type of procedure or treatment to be provided or the type of 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 difficult to control arbitrarily, and they can be understood as specific values.

[0428] Next, the width W of the mixing portion may be designed. The width W of the mixing module 1000 may be determined in consideration of the size of the refrigerant providing device 2000, the size of the refrigerant injection unit 2100 or the refrigerant injection hole 2110, and / or the injection amount of the composition. As an example, as the refrigerant providing device 2000 or the refrigerant injection hole 2110 increases, the width W of the mixing portion may increase. At the same time, as the width W of the mixing portion increases, the injection amount of the composition increases, and therefore, the width W of the mixing portion may be readjusted later.

[0429] Considering the design width W of the mixing portion, the film width FW of the spreading film 1620 can be designed. The spreading film 1620 can be preferably formed to surround the mainstream MS of the refrigerant, and the size of the mainstream MS of the refrigerant changes according to the size of the refrigerant injection hole 2110, so the film width FW can be designed considering the size of the refrigerant injection hole 2110.

[0430] Finally, the tube width TW can be designed. Here, as the tube width TW increases, the spray amount of the composition increases, which can be taken into account.

[0431] In order to design a hybrid module 1000 that satisfies the same consumption time condition, some of the above variables may be set as independent variables, and when the independent variables are changed, experiments may be conducted to monitor whether the same consumption time condition is satisfied.

[0432] The mixing module 1000 or the spreading membrane 1620 may be designed using the values ​​of the variables calculated in the experiments performed.

[0433] As an example, when the capacity of the box CTR, the pressure of the refrigerant, the size of the refrigerant injection hole 2110, the width W of the mixing section, and the membrane width FW are fixed to specific values, and when the type of composition and the required usage of the composition are determined, when the tube width TW is changed, the consumption time of the refrigerant and the consumption time of the composition are monitored to be basically the same, and the value of the tube width TW can be calculated when the same consumption time condition is met.

[0434] The mixing module 1000 may be designed to have a calculated value of the tube width TW and a specified width W of the mixing portion, and the spreading film 1620 may be designed to have a specified film width FW.

[0435] As another example, when the capacity of the box CTR, the pressure of the refrigerant, the size of the refrigerant injection hole 2110, the width W of the mixing section, and the tube width TW are fixed to specific values, and the type of composition and the required usage of the composition are determined, when the film width FW is changed, the consumption time of the refrigerant and the consumption time of the composition are monitored to see whether they are basically the same, and the value of the film width FW can be calculated when the same consumption time condition is met.

[0436] The spreading film 1620 may be designed to have a calculated film width FW, and the mixing module 1000 may be designed to have a specified tube width TW and a specified mixing section width W.

[0437] 7. Cover design

[0438] In the following, reference will be made to Fig.28 The cover COV designed to protect the sensor unit 2600 of the refrigerant supplying device 2000 is described.

[0439] Fig.28 is a view showing a process of sequentially coupling a cover and a mixing module to a body according to one embodiment. Specifically, Fig.28 (a) is a view showing a process of coupling the cover COV to the main body (MB), and Fig.28 (b) is a view showing a process of coupling the mixing module 1000 to the refrigerant supplying device 2000 .

[0440] refer to Fig.28 (a), a sensing hole SH may be formed in the body MB. The sensing hole SH is a component that prevents the sensing region SR of the sensor unit 2600 embedded in the body MB from being blocked. The sensing hole SH may be designed so that the sensing region SR of the sensor unit 2600 passes therethrough. In other words, the sensing path of the sensor unit 2600 may be fixed by the sensing hole SH.

[0441] Meanwhile, when the composition is sprayed onto a target using the mixture spraying system 100, some of the sprayed composition may penetrate the target surface and be absorbed by the target, and some of the sprayed composition may hit the target surface and splash back. Here, there is a possibility that the sensor unit 2600 is contaminated, for example, the splashed composition is deposited on the sensor unit 2600 through the sensing hole SH.

[0442] In addition, the refrigerant supply device 2000 can be used independently for a cooling process of spraying a refrigerant onto the surface of a target, but as described above, the refrigerant supply device 2000 can be used as a 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 necessary. In other words, measurement of the target surface temperature by the sensor unit 2600 may not be performed.

[0443] Considering the above situation, it is necessary to cover the sensing hole SH to prevent contamination of the sensor unit 2600. Fig.28 (a), the cover COV may be designed to include a covering portion SP to cover the sensing hole SH.

[0444] When the cover COV is coupled to the body MB, the covering portion SP of the cover COV may cover at least a portion of the sensing hole SH. Fig.28 In (a), the height SPH of the covering portion may correspond to the diameter or width of the sensing hole SH. Fig.28 In (a), the height SPH of the covering portion may be determined based on the distance between the nozzle 2100 and the sensing hole SH.

[0445] refer to Fig.28 (b), when the mixing module 1000 is coupled to the refrigerant providing device 2000, the sensing hole SH may be covered. Specifically, when the cover COV is coupled to the body MB, at least a portion of the sensing hole SH is covered, but when the mixing module insertion portion MI is disposed 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 providing 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 covering portion SP of the cover COV and the rear surface RS of the mixing module 1000.

[0446] 8. Example of using a mixed injection system

[0447] In the following, reference will be made to Fig.29 A process for injecting a refrigerant and a composition using the mixture injection system 100 is described.

[0448] Fig.29 is a view showing a use process of a mixture injection system according to one embodiment.

[0449] First, the user can fill the mixing module 1000 with the composition. For example, referring to Fig.29 , the user may transfer the composition stored in the ampoule to the composition storage portion 1300 of the mixing module 1000 using a syringe.

[0450] The mixing module may include a composition injection hole CIH which is fluidically connected to the composition storage part 1300 and through which the injection needle passes.

[0451] The user may couple the cartridge CTR storing refrigerant to the body MB. When the cartridge CTR is coupled to the cartridge coupling unit 2500 of the body MB, the sealing portion of the cartridge CTR is opened so that the inside of the cartridge CTR and the refrigerant channel in the body MB can be connected to each other.

[0452] A user may couple the mixing module 1000 to the refrigerant providing device 2000 .

[0453] The order of the combination of the refrigerant providing device 2000 and the mixing module 1000 and the combination of the main body MB and the box CTR can be determined arbitrarily. In other words, the user can combine the box CTR after connecting the mixing module 1000 to the refrigerant providing device 2000, or the user can combine the mixing module 1000 to the refrigerant providing device 2000 after connecting the box CTR to the main body MB.

[0454] Meanwhile, the process of filling the mixing module 1000 with the composition may be performed after coupling the mixing module 1000 to the refrigerant providing device 2000 .

[0455] After the assembly of the mixture injection system 100 is completed, the user may inject the composition and the refrigerant to a target.

[0456] After finishing using the mixture injection system 100, the user may reverse the above-described assembly process of the mixture injection system 100. For example, the user may separate the mixture injection system 100 into the mixing module 1000 and the refrigerant providing device 2000, and remove the cartridge CTR from the refrigerant providing device 2000.

[0457] Meanwhile, during the use of the mixture injection system 100, a situation may occur where the cartridge CTR or the mixing module 1000 needs to be replaced. Here, a procedure may be determined based on whether the refrigerant stored in the cartridge CTR is exhausted according to the use of the mixture injection system 100. However, the technical idea of ​​the present disclosure is not limited thereto, and a procedure may be determined based on whether the composition filled in the mixing module 1000 is exhausted.

[0458] During use of the mixture injection system 100, a situation may occur in which the composition stored in the mixing module 1000 is exhausted but the refrigerant stored in the cartridge CTR is not exhausted. In this case, the user may additionally fill the mixing module 1000 with the composition and inject the composition and the refrigerant until the refrigerant stored in the cartridge CTR is exhausted. Alternatively, if a criterion for determining a procedure is whether the composition in the mixing module 1000 is completely consumed, the user may replace the cartridge CTR after injecting all the refrigerant in the cartridge CTR using the mixture injection system 100.

[0459] There may be a situation where the program processing method is to sequentially spray the first composition and the second composition with different effects. In this case, the user can fill the first mixing module with the first composition, then combine the refrigerant providing device 1000 to spray the refrigerant and the first composition, and then fill the second mixing module with the second composition, and then combine the refrigerant providing device 1000 to spray the refrigerant and the second composition. In this case, the first part of the program time for spraying the first composition and the second part of the program time for spraying the second composition can be determined based on the program time when the refrigerant stored in the box CTR is exhausted. In addition, the first part of the program time can be considered to determine the amount of the first composition filled in the first mixing module, and the second part of the program time can be considered to determine the amount of the second composition filled in the second mixing module.

[0460] When a new program is performed after using the mixture injection system 100, the cartridge (CTR) needs to be replaced. In the case of performing a new program, the previously used cartridge (CTR) can be replaced with a new cartridge (CTR) regardless of whether the refrigerant remains. This is because the program time is determined based on whether the refrigerant in the cartridge (CTR) is exhausted (CTR).

[0461] Meanwhile, 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 manipulate the refrigerant supply device 2000 to spray the refrigerant until the refrigerant stops spraying, 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 keeps it incompletely separated, 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 may be completely separated.
