For example, as shown in (b) of FIG. 5 , when the adapter 2100 is mounted on the mixing module 1000 and a part of the adapter coupling part 2120 is located inside the mixing part 1100, the adapter coupling A space surrounded by the portion 2120 may constitute at least a part of the mixing space MA. Here, the adapter coupler 2120 may be implemented in a half-ring shape or a curved curved shape in addition to the ring shape shown in FIG. 6 to constitute a part of the mixing space MA.

As described above, since the adapter coupling part 2120 constitutes at least a part of the mixing space MA, the composition can directly move into the mixing space MA through the inlet 2130 built in the adapter coupling part 2120. there is. In this case, the position and direction at which the composition is introduced into the mixing space MA may be determined according to the shape of the adapter coupling unit 2120 or the position of the inlet 2130 on the adapter coupling unit 2120 . In other words, since the adapter coupler 2120 constitutes at least a part of the mixing space MA, it is possible to more easily specify the positional relationship between the inlet path of the composition and the jetting path of the coolant in the mixing space MA.

The adapter coupling part 2120 may be connected to the adapter body 2110. For example, the adapter coupling part 2120 may extend from the adapter body 2110 and not be physically separated from the adapter body 2110 . For another example, the adapter coupling part 2120 may be physically separated from the adapter body 2110 and assembled.

The adapter 2100 may be coupled to the mixing module 1000 through an adapter coupling part 2120 .

For example, the adapter 2100 includes a slide space formed between the adapter coupling part 2120 and the adapter body 2110, and at least a part of the mixing module 1000 is inserted into the slide space so that the adapter 2100 is mixed. It can be slidably coupled to the module 1000. As shown in (c) and (d) of FIG. 6, the slide space may include first and second slide grooves 2121a and 2121b formed while the adapter body 2110 surrounds the adapter coupling part 2120. can Alternatively, a slide rail in which at least a portion of the adapter coupling portion 2120 protrudes or has a groove may be used for slide coupling.

As another example, the adapter coupling unit 2120 may be coupled to the mixing module 1000 through the aforementioned screw coupling, and for this purpose, at least a portion of the adapter coupling unit 2120 may be a female screw or a male screw.

The inlet 2130 may form a flow path through which the composition may move. For example, the inlet 2130 may be implemented in the form of a conduit extending from one end 2131 of the inlet to the other end 2132 of the inlet. Specifically, one end 2131 of the inlet may be fluidly connected to the composition container 2200 and the other end 2132 of the inlet may be fluidly connected to the mixing module 1000 . The inlet 2130 may guide the composition moving from the composition container 2200 to the mixing module 1000 .

The inlet 2130 may be located inside the adapter body 2110 and/or the adapter coupling part 2120. For example, referring to (a), (b), and (d) of FIG. 6, a part of the inlet 2130 is located inside the adapter body 2110, and another part of the inlet 2130 is coupled to the adapter. It may be located inside section 2120 . At this time, one end of the inlet 2131 is formed on the adapter body 2110 coupled to the composition container 2200, as shown in (b) and (d) of FIG. 6, and the other end of the inlet 2132 is shown in FIG. As shown in (a) and (b) of 6, it may be formed in the adapter coupling part 2120 connected to the mixing module 1000.

The auxiliary guide unit 2140 may assist a user to maintain a distance between the complex function module 1000 and the skin when the mixed injection system operates. The auxiliary guide part 2140 may be implemented in a form protruding from the adapter body 2110 in one direction. For example, referring to FIGS. 5 and 6 , based on the state in which the adapter 2100 is coupled to the mixing module 1000, the auxiliary guide part 2140 is sprayed from the adapter body 2110 in the direction in which the coolant and composition are sprayed. can be extruded.

The auxiliary guide part 2140 may have a shape surrounding a central axis parallel to the spraying direction. For example, referring to (c) of FIG. 6 , the auxiliary guide part 2140 may have a shape surrounding the central axis by a first angle based on the central axis. At this time, the first angle at which the auxiliary guide part 2140 surrounds the central axis may vary according to the degree of sealing of the coolant and the composition during the operation of the mixed injection system 10 . As the sealing degree increases, the first angle may have a larger value. The first angle may be set between 0 and 360 degrees. The first angle may be preferably set between 30 degrees and 180 degrees.

The auxiliary guide part 2140 may have a different material or material from that of the adapter body 2120 . For example, the auxiliary guide portion 2140 may be made of a material that is relatively more flexible than the adapter body 2120 .

The protruding length of the auxiliary guide part 2140 may correspond to the length of the guide part 3000 . For example, referring to (b) of FIG. 5 , the degree of protrusion of the auxiliary guide part 2140 along the spraying direction with respect to the mixing module 1000 in a state in which the adapter 2100 is coupled to the mixing module 1000 and the degree of protrusion of the guide part 3000 may correspond to each other. Specifically, in a state where the adapter 2100 is coupled to the mixing module 1000, the distance from the end of the mixing module 1000 to the end of the auxiliary guide part 2140 is the distance from the end of the mixing module 1000 to the end of the guide part 3000. may be equal to the distance to the end of In this case, when contacting the skin surface through the auxiliary guide unit 2140 and the guide unit 3000, the spray direction to the skin surface may be substantially vertical.

The shape of the auxiliary guide part 2140 may correspond to the shape of the guide part 3000 . For example, referring to (a) of FIG. 5 , when the guide part 3000 is divided into a guide part connection part coupled with the coolant supply device 200 and a contact part for contacting the skin, the auxiliary guide part 2140 The contact part of the guide part 3000 surrounds the central axis of the complex function module 100 parallel to the injection direction, and the shape of the auxiliary guide part 2140 and the contact part of the guide part 3000 are symmetrical about the central axis. can be achieved

7 is a view showing a composition container 2200 according to an embodiment of the present specification. Referring to FIG. 7 , the composition container 2200 may be divided into a case 2210, a cap portion 2220, and a cover (not shown).

The case 2210 may provide a composition accommodating space 2211 for accommodating the composition.

Case 2210 may be coupled to adapter 2100 . For example, one end of the case 2210 may be coupled to the adapter body 2110. As a method of coupling the case 2210 to the adapter 2100, screw coupling, interference fit coupling, magnetic coupling, slide coupling, and the like may be used.

The case 2210 may have a shape corresponding to the shape of the adapter body 2110 .

The cap portion 2220 may be coupled to the other end of the case 2210 to seal at least a portion of the composition accommodating space 2211 .

The cap portion 2220 may include a stepped portion 2222 for coupling with the case 2210 .

The cap part 2220 may include an outside air inlet 2221 for introducing outside air. As will be described later, the outside air inlet 2221 may refer to a portion through which outside air is introduced while the mixed injection system 10 is driven. The outside air inlet 2221 does not necessarily have to be formed in the cap 2220, and the outside air inlet 2221 is a portion fluidly connected to the composition accommodating space 2211 such as the case 2210 or the adapter body 2110. can be formed in

The cap portion 2220 may have a shape corresponding to that of the case 2210 .

Meanwhile, the composition container 2200 is not limited to including the above-described configuration. A product containing the composition, for example, a cosmetic product such as an ampoule or a vial, or a pharmaceutical product may also be the composition container 2200 .

8 is a diagram illustrating a mixing module 1000 according to an embodiment of the present specification. Referring to FIG. 8 , the mixing module 1000 may be divided into an injection unit 1100 , a mixing unit 1200 and a coupling unit 1300 .

The spraying unit 1100 may spray the passing coolant. The injection unit 1100 may include a narrowing portion. For example, the ejection unit 1100 may include an inflow hole 1101 through which coolant is introduced and a ejection hole 1102 through which coolant is ejected. A diameter of the inlet hole 1101 may be greater than a diameter of the spray hole 1102 . As the coolant passes through the spraying unit 1100, the pressure is lowered and the moving speed is increased at the portion where the width is narrowed, so that the coolant may be sprayed while expanding.

The injection unit 1100 is disposed between the mixing space MA of the mixing unit 1200 and the coupling space CA of the coupling unit 1300 and is connected to the coupling unit 1300 from the coolant supply device 200. Coolant may be provided and injected into the mixing space MA. The characteristics of the ejection unit 1100 and the resulting coolant injection form will be described later.

The mixing unit 1200 may provide a mixing space MA for mixing the coolant and the composition. For example, as shown in FIG. 8 , the mixing unit 1200 may have a cylindrical mixing space MA. The shape of the mixing space MA may vary depending on the internal shape of the mixing unit 1200 (eg, a polygonal column, a truncated cone whose width decreases or increases toward the bottom). Furthermore, as will be described later, the shape of the mixing space MA may vary depending on components other than the mixing unit 1200 (eg, the inner space of the adapter coupling unit 2120).

A coolant and a composition may flow into the mixing space MA. For example, as described above, the coolant injected through the injection unit 1100 flows into the mixing space MA, and the composition stored in the composition container 2200 is mixed through the inlet 2130 of the adapter 2100. It may flow into the space MA. At this time, the composition may be introduced into the mixing space MA by spraying the coolant, and a method and structure of the composition being introduced will be described later.

Mixing unit 1200 may be combined with adapter 2100 . The mixing unit 1200 may include a mounting area EA to be coupled with the adapter 2100 and a coupling member 1210 . Here, the mounting area EA may refer to an area into which at least a portion of the adapter 2100 is inserted or an area coupled to at least a portion of the adapter 2100 . Also, the coupling member 1210 may be understood as a means for coupling the adapter 2100 and the mixing unit 1200.

For example, when the mixing unit 1200 and the adapter 2100 are coupled by a slide coupling, as shown in FIG. 8 , the coupling member 1210 of the mixing unit 1200 slides the adapter coupling unit 2120 described above. It may be implemented in the form of a slide plate inserted into the space. In addition, the adapter coupling part 2120 is inserted into the mounting area EA of the mixing unit 1200, and the coupling member 1210 of the mixing unit 1200 is positioned between the adapter coupling part 2120 and the adapter body 2110. can do.

As another example, when the mixing unit 1200 and the adapter 2100 are screwed together, the coupling member 1210 of the mixing unit 1200 may be a female screw or a male screw for screwing with the adapter coupling unit 2120. .

Meanwhile, since the mixing unit 1200 includes the mounting area EA, the composition may directly flow into the mixing space MA from the inlet 2130 of the adapter 2100 . In other words, when the mixing unit 1200 includes a receiving member other than the mounting area EA, the composition passes through the inlet 2130 of the adapter 2100 and passes through the receiving member of the mixing unit 1200 to the mixing space MA. ) can enter. However, in this case, in order to prevent leakage of the composition between the inlet 2130 and the accommodating member of the mixing unit 1200, a precise design is required so that there is no gap between the inlet 2130 and the accommodating member of the mixing unit 1200. required, which may increase the production cost. Therefore, it is more preferable that the mixing unit 1200 includes the mounting area EA so that the composition directly flows into the mixing space MA through the adapter coupling unit 2120 .

In the above, the case where the mounting area EA and the coupling member 1210 are included in the mixing unit 1200 has been described, but the technical spirit of the present specification is not limited thereto, and the mounting area EA and/or the coupling member ( 1210 may be implemented in any part of the blending module 1000 . In addition, the mixing unit 1200 does not necessarily include the mounting area EA and the coupling member 1210, and when the composition flows into the mixing space MA through a separate flow path such as a pipe or a hose, the mounting area (EA) and/or coupling member 1210 may be omitted.

The mixing unit 1200 may provide an internal space in which the spraying unit 1100 is disposed. For example, referring to FIG. 8 , the mixing unit 1200 may include an internal space connected to the mixing space MA, and the injection unit 1100 may be located in the internal space of the mixing unit 1200 .

The coupling part 1300 may be coupled to the coolant supply device 200 . The coupling part 1300 may provide a coupling space CA for accommodating at least a portion of the coolant supply device 200 .

The coupling part 1300 may include a main coupling part 1310 and an auxiliary coupling part 1320 . The main coupling part 1310 may provide a coupling space CA, and may be coupled with the coolant supply device 200 in the coupling space CA. The main coupling part 1310 may include coupling means for coupling with the coolant supply device 200 . For example, the main coupler 1310 may include a male screw or a female screw to screw into the coolant supply device 200 .

The auxiliary coupler 1320 may fix the injection unit 1100 and the mixing unit 1200 . For example, the auxiliary coupling part 1320 presses the spraying part 1100 and the mixing part 1200 in a direction parallel to the central axis to mix them while the mixing module 1000 is coupled to the coolant supply device 200. After the module 1000 and the coolant supply device 200 are coupled, the injection unit 1100 and the mixing unit 1200 may be prevented from moving.

Specifically, referring to FIG. 8 , the mixing unit 1200 includes the locking jaw 1220, and when the main coupling unit 1310 moves in a direction parallel to the central axis while being coupled with the coolant supply device 200, the auxiliary The coupling part 1320 moves together with the main coupling part 1310 and presses the locking jaw 1220 of the mixing unit 1200 so that the spraying unit 1100 and the mixing unit 1200 are centered with the coolant supply device 200. can be fixed in a shared state. In addition, in this case, while the main coupling unit 1310 rotates for screw coupling, the mixing unit 1200 can be fixed in a non-rotating state when viewed from the direction of the central axis, thereby supplying the composition coupled to the mixing unit 1200. The module 2000 may also not rotate when viewed from the direction of the central axis. As a result, the stability of the mixed injection system 10 in which the complex function module 100 and the coolant supply device 200 are combined is improved, and furthermore, when using the mixed injection system 10, the balance is balanced to increase convenience.

The main coupling part 1310 and the auxiliary coupling part 1320 may be fixed to each other through a fixing member. For example, as shown in FIG. 8 , the main coupling part 1310 and the auxiliary coupling part 1320 have at least two pairs of holes corresponding to each other, and the first and second fixing members 1330a and 1330b respectively By being inserted into the pair of holes, the main coupling part 1310 and the auxiliary coupling part 1320 may be fixed to each other.

The support part 1400 may support the injection part 1100 . The support part 1400 may be disposed between the coupling space CA of the coupling unit 1300 and the injection unit 1100 . As will be described later, the injection unit 1100 may be fixed to the coolant supply device 200 through the support unit 1400 . The support part 1400 can prevent the coolant from leaking in the process of coupling the mixing module 1000 to the coolant supply device 200 or in the process of moving the coolant from the coolant supply device 200 to the ejection part 1100. .

The support part 1400 may provide a passage through which the coolant moves. The support part 1400 may include a hollow to provide a passage through which the coolant moves. The size of the hollow of the support part 1400 may correspond to the size of the inlet hole 1101 of the injection part 1100 . The hollow size of the support part 1400 may correspond to the size of the outlet hole of the module coupling part 220 of the coolant supply device 200 . The size of the hollow of the support part 1400 corresponds to the size of the inlet hole 1101 of the spray part 1100 at one end of the support part 1400 connected to the spray part 1100, and the support part connected to the module coupling part 220. The other end of 1400 may correspond to the size of the outflow hole of the module coupling part 220 . In other words, depending on the size of the inlet hole 1101 of the injection unit 1100 and the size of the outlet hole of the module coupling unit 220, the size of the hollow of the support part 1400 may be different or the same at both ends of the support part 1400. there is.

[How to use the mixed injection system]

Hereinafter, a method of using the mixed injection system 10 will be described with reference to FIGS. 9 to 12 .

9 is a flowchart illustrating a method of using the mixed injection system 10 according to an embodiment of the present specification. 10 is a view showing a process in which the composition supply module 2000 according to an embodiment of the present specification is prepared, and FIG. 11 is a coolant supply device 200 and a mixing module 1000 according to an embodiment of the present specification. 12 is an exploded view, and FIG. 12 is a view illustrating a process of coupling the multifunction module 100 to the coolant supply device 200 according to an embodiment of the present specification.

Referring to FIG. 9 , the method using the mixed injection system 10 includes coupling the case 2210 to the adapter 2100 (S110), injecting the composition into the case 2210 and sealing it (S120), coolant The step of coupling the mixing module 1000 to the supply device 200 (S130), the step of coupling the guide unit 3000 to the coolant supply device 200 (S140), the composition supply module 2000 to the mixing module 1000 ) may include combining (S150), and mixing and spraying the coolant and the composition (S160).

Each step is described in detail below.

First, the case 2210 may be coupled to the adapter 2100 (S110). For example, referring to FIG. 10 , the case 2210 may be coupled to the adapter body 2110 to seal one end of the case 2210 . In detail, the adapter body 2110 may include a step or a locking portion corresponding to one end of the case 2210, and the case 2210 may be coupled to the adapter body 2110 in an interference fit manner. At this time, the composition accommodating space 2211 of the case 2210 may be fluidly connected to the inlet end 2131, and the leakage of the composition may be minimized because the diameter of the inlet end 2131 is sufficiently small.

Thereafter, the composition may be injected into the case 2210 and sealed (S120). For example, referring to FIG. 10 , a composition may be injected into a case 2210 having one end sealed by an adapter 2100 . Compositions may be supplied from cosmetic or medical products. After the composition is injected into the sealed case 2210 , the cap portion 2220 is coupled to seal the case 2210 . Meanwhile, the case 2210 in a sealed state may be fluidly connected to the outside through the inlet 2130 of the adapter 2100 at one end and the outside air inlet 2221 of the cap 2220 at the other end. there is.

Steps (S110) and step (S120) may be understood as a step of preparing the composition supply module (2000). In other words, the composition supply module 2000 in a state in which the composition is stored through steps S110 and S120 may be provided.

Next, the mixing module 1000 may be coupled to the coolant supply device 200 (S130). The coolant supply device 200 may be prepared in a state in which the nozzle 210 is separated for coupling with the mixing module 1000 .

For example, the coupling part 1300 of the mixing module 1000 may be coupled to the module coupling part 220 of the coolant supply device 200 through screw coupling. For example, the coupling unit 1300 may include a female screw or male screw portion, and the module coupling unit 220 may include a male screw or female screw portion corresponding to the coupling unit 1300 . Here, the mixing module 1000 and the module coupler 220 may be coupled in a coaxially disposed state. Specifically, referring to FIG. 11 , while the main coupling part 1310 of the mixing module 1000 rotates while the central axis of the mixing module 1000 and the central axis of the module coupling part 220 are arranged on the same line, the module The coupling part 220 is screwed together, and accordingly, the auxiliary coupling unit 1320 presses the mixing unit 1200 in the opposite direction to the spraying direction to form the injection unit 1100 and the support unit 1400 into the module coupling unit 220. can be fixed on

As another example, the coupling part 1300 of the mixing module 1000 may be coupled to the module coupling part 220 of the coolant supply device 200 through interference fit, slide coupling, or magnetic coupling.

Meanwhile, when the mixing module 1000 is coupled to the coolant supply device 200, the support 1400 may be disposed between the injection unit 1100 and the module coupling unit 1300. Since the support part 1400 is disposed between the injection part 1100 and the module coupling part 1300, damage to the injection part 1100 and the module coupling part 1300 due to external force or coolant movement may be prevented. The support part 1400 may include a shape corresponding to each of the injection part 1100 and the module coupling part 1300 . Specifically, when one end of the support part 1400 contacts the ejection part 1100, one end of the support part 1400 may include a first groove for accommodating at least a part of the ejection part 1100. Additionally, when the other end of the support part 1400 contacts the module coupling part 1300, the other end of the support part 1400 may include a second groove for accommodating at least a part of the module coupling part 1300.

After the mixing module 1000 is coupled to the coolant supply device 200, the guide unit 3000 may be coupled to the coolant supply device 200 (S140). The guide unit 3000 may be coupled to the coolant supply device 200 in various ways, such as interference fit, screw coupling, magnetic coupling, and/or sliding coupling. For example, referring to FIG. 12 , the main body MB of the coolant supply device 200 has a magnetic material, and the guide part 3000 includes a corresponding magnetic material so that the guide part 3000 is the coolant supply device 200. can be coupled magnetically. According to one embodiment of the present application, the main body (MB) of the coolant supply device 200 may be provided so that the magnetic material is not exposed, and the guide part 3000 may be provided so that the corresponding magnetic material is exposed, but is not limited thereto. don't

In a state in which the mixing module 1000 is coupled to the coolant supply device 200, the composition supply module 2000 may be coupled to the mixing module 1000 (S150). As described above, the composition supply module 2000 may be mounted on the mounting area EA of the mixing module 1000. For example, referring to FIG. 12 , the composition supply module 2000 may be mounted on the mounting area EA of the mixing module 1000 through a slide coupling. At this time, the direction in which the composition supply module 2000 is mounted on the mixing module 1000 may be opposite to the spraying direction.

Meanwhile, the direction in which the composition supply module 2000 is mounted on the mixing module 1000 is not limited to a direction opposite to the spraying direction. For example, the composition supply module 2000 may be mounted on the mixing module 1000 in a direction oblique or perpendicular to the spraying direction. In addition, the composition supply module 2000 may be mounted to the mixing module 1000 using screw coupling, interference fit coupling, and/or magnetic coupling in addition to slide coupling.

However, when the composition supply module 2000 is mounted in a direction parallel to the spraying direction, the degree of protrusion of the composition supply module 2000 from the central axis may be relatively smaller than when the composition supply module 2000 is mounted in another direction. When the mixing space MA of the mixing module 1000 in which the coolant and the composition are mixed must have a certain size, when the composition supply module 2000 is coupled in a direction that is not parallel to the spraying direction, a direction parallel to the spraying direction This is because the distance to the end of the composition supply module 2000 based on the central axis is greater than in the case of FIG. The more the composition supply module 2000 protrudes from the central axis where the coolant and the composition are sprayed, the more the user's view may be obstructed in the process of using the mixed spray system 10, the composition supply module 2000 is in the spray direction. It is more preferable to mount them in a parallel direction.

In addition, when considering usability or convenience, a slide coupling is more preferable than a screw coupling or an interference fit coupling, and a slide coupling is more preferable than a magnetic coupling when considering robustness or stability.

As a result, the composition supply module 2000 is preferably mounted to the mixing module 1000 through a sliding coupling in a direction parallel to the spraying direction, but the technical spirit of the present specification is not limited thereto.

Finally, the coolant and composition may be mixed and sprayed (S160). After the complex function module 100 is coupled to the coolant supply device 200, the coolant supply device 200 may operate similarly to that described in FIG. 3. Specifically, the coolant supply device 200 receives an input signal according to a user's manipulation, sets a target cooling temperature and a target cooling time, and controls the flow rate controller 240 to supply the coolant stored in the cartridge CTR to the complex function module. (100) can be provided. The complex function module 100 may mix the coolant supplied from the coolant supply device 200 with the composition and spray it. A process of mixing and spraying the coolant and the composition in the complex function module 100 will be described later.

In step S160 of mixing and spraying the coolant and the composition, the temperature of the coolant and the composition may be controlled. For example, the coolant supply device 200 measures the temperature of a target to which the coolant and composition are sprayed through the sensor unit 260, and controls the temperature control unit 230 based on the measured temperature to control the coolant and composition. You can control the temperature. Here, the temperature of the coolant and the composition may be adjusted according to a previously set target cooling temperature, and the target cooling temperature depends on the purpose of use of the mixed injection system 10, the composition used, or the type of active ingredient included in the composition. can be determined

When mixing and spraying the coolant and the composition, the target cooling temperature may be set within an appropriate range.

A target cooling temperature may be determined between -30°C and 30°C. Alternatively, the target cooling temperature is -30 ° C to 25 ° C, -30 ° C to 20 ° C, -30 ° C to 15 ° C, -30 ° C to 10 ° C, -30 ° C to 5 ° C, -30 ° C to 0 ° C, -30 ° C ℃ to -5 ℃, -30 ℃ to -10 ℃, -30 ℃ to -15 ℃, -30 ℃ to -20 ℃, -30 ℃ to -25 ℃, -25 ℃ to 30 ℃, -20 ℃ to 30 ℃, -15 ℃ to 30 ℃, -10 ℃ to 30 ℃, -5 ℃ to 30 ℃, 0 ℃ to 30 ℃, 5 ℃ to 30 ℃, 10 ℃ to 30 ℃, 15 ℃ to 30 ℃, 20 ℃ to 30°C, or between 25°C and 30°C.

Alternatively, the target cooling temperature is -30°C, -25°C, -20°C, -15°C, -10°C, -5°C, 0°C, 5°C, 10°C, 15°C, 20°C, 25°C, or 30°C. It can be set to °C.

Meanwhile, the coolant supply device 200 may control the temperature of the target to be within a preset temperature range without controlling the temperature of the target to a preset target cooling temperature.

Here, the temperature range may be a range selected from -30 °C to 30 °C. For example, the temperature range is -30°C to 25°C, -30°C to 20°C, -30°C to 15°C, -30°C to 10°C, -30°C to 5°C, -30°C to 0°C, - 30°C to -5°C, -30°C to -10°C, -30°C to -15°C, -30°C to -20°C, -30°C to -25°C, -25°C to 30°C, -20°C to 30°C, -15°C to 30°C, -10°C to 30°C, -5°C to 30°C, 0°C to 30°C, 5°C to 30°C, 10°C to 30°C, 15°C to 30°C, 20°C to 30°C, or 25°C to 30°C.

Alternatively, the temperature range may be -5°C to 5°C, 0°C to 8°C, or 2°C to 8°C.

Meanwhile, the above-described steps (S110, S120, S130, S140, S150, and S160) do not necessarily have to be performed sequentially and may be performed in a different order as follows.

The step of injecting and sealing the composition into the case 2210 (S120) may be performed in parallel with the step of coupling the case 2210 to the adapter 2100 (S110). For example, the composition is injected in a state where the other end of the case 2210 is sealed by the cap portion 2220, and after the composition is injected, the adapter 2100 is coupled to one end of the case 2210 so that the composition supply module 2000 ) can be prepared.

Alternatively, the mixing module 1000 may be coupled after the guide unit 3000 is coupled to the coolant supply device 200 . Alternatively, after the composition supply module 2000 is mounted on the mixing module 1000, the mixing module 1000 may be coupled to the coolant supply device 200.

[Mixed injection system design conditions]

In order for the mixture injection system 10 to operate as described above, its components must be designed to satisfy specific conditions. Hereinafter, with reference to FIGS. 13 to 17 , a process of operating the mixed injection system 10 and design conditions that components of the mixed injection system 10 must satisfy will be described. 13 to 17 show a state in which the complex function module 100 and the coolant supply device 200 are coupled, but some components are omitted for convenience of description. In FIGS. 13 to 16, the coolant supply device 200 and the guide unit 3000 are omitted, and in FIG. 17(b), the composition supply module 2000 and the guide unit 3000 are omitted.

13 is a cross-sectional view of some components of the mixed injection system 10 according to an embodiment of the present specification. 13 shows the composition supply device 2000 and the mixing module 1000 in a state in which the coolant and composition 2 are not sprayed.

The mixing unit 1200 of the mixing module 1000 and the adapter coupling unit 2120 of the adapter 2100 may each have a predetermined inner diameter. Referring to FIG. 13 , the mixing unit 1200 may have a first inner diameter R1. The adapter coupling portion 2120 may be divided into a portion having a second inner diameter R2 and a portion having an inner diameter gradually increasing from the second inner diameter R2 to the third inner diameter R3.

The mixing module 1000 may provide a mixing space MA. The mixing space MA may be understood as a concept including a space in which the composition and the coolant are mixed according to the operation of the mixing injection system 10 . As will be described later, the mixing space MA may be an internal space of the mixing unit 1100 or a specific part of the internal space of the mixing unit 1100, and may be shaped by the mixing unit 1100 and/or the adapter 2100. size can be determined.

The mixing space MA may have a preset width in a direction perpendicular to the central axis of the mixing module 1000 . The width of the mixing space MA may correspond to the inner diameter of the mixing unit 1200 or the inner diameter of the adapter coupling unit 2120 of the mixing module 1000 . For example, as shown in FIG. 13 , the adapter coupling portion 2120 is slide-coupled to the mixing module 1000 and a part of the adapter coupling portion 2120 has a shape corresponding to the mixing unit 1200, and the adapter coupling portion When a portion of the 2120 is inserted into the mixing unit 1200, the width of the mixing space MA may be determined between the second inner diameter R2 and the third inner diameter R3 of the adapter coupling part 2120. . For another example, when the adapter coupling portion 2120 is slidably coupled to the mixing module 1000 but a portion of the adapter coupling portion 2120 is not inserted into the mixing unit 1200, the width of the mixing space MA is It may be determined as the first inner diameter R1 of the mixing unit 1200. In other words, when at least a portion of the adapter coupling portion 2120 is inserted into the mixing portion 1200, the width of the mixing space MA is determined by at least the shape or inner diameter of the adapter coupling portion 2120, and the adapter coupling portion When 2120 does not affect the inside of the mixing unit 1200, the width of the mixing space MA may be determined by the inner diameter of the mixing unit 1200.

The mixing space MA may be fluidly coupled to the composition container 2200 . For example, referring to FIG. 13 , the mixing space MA may be connected to the case 2210 of the composition container 2200 through the inlet 2130 . Specifically, one end 2131 of the inlet may be connected to the case 2210 and the other end 2132 of the inlet may be connected to the mixing space MA.

Here, the injection part 1100 and the part into which the composition 2 flows into the mixing space MA may have a certain distance. For example, referring to FIG. 13 , the other end 2132 of the inlet may be spaced apart from the end of the injection part 1100 by a first distance D1 based on the central axis. The first distance D1 is related to the aforementioned design condition, which will be described later.

As long as the coolant is not sprayed, the composition 2 may not flow into the mixing space MA. Specifically, the composition 2 stored in the composition container 2200 may not flow into the inlet 2130 unless external pressure changes. At this time, the size of the diameter of one end 2131 of the inlet and/or the diameter of the other end 2132 of the inlet may be small enough to prevent the composition from flowing in.

The diameter of the inlet 2130 may be determined according to a target flow rate of the composition. For example, the flow rate of the composition may be proportional to the fourth power of the diameter of the inlet 2130, inversely proportional to the length of the inlet 2130, and inversely proportional to the viscosity of the composition, where the diameter of the inlet 2130 is The flow rate of may be set to a preset target flow rate. Specifically, the composition may have a minimum viscosity of water, and in this case, the diameter of the inlet 2130 may be selected from 0.4 mm to 1.5 mm. Preferably, the diameter of the inlet portion 2130 may be 0.6 mm.

Prior to describing a process in which the composition 2 is introduced into the mixing space MA, a form of coolant spraying by the spraying unit 1100 will be first described.

FIG. 14 is a diagram showing a spray shape of the spraying unit 1100 and the sprayed coolant according to an embodiment of the present specification.

The coolant sprayed from the ejection unit 1100 may have a spray form. Referring to (b) of FIG. 14 , the spray shape of the coolant may be formed according to the spray angle NA and the spray distance ND.

The spray angle NA may refer to an angle at which the coolant spreads at the moment when the coolant is sprayed from the spray unit 1100 . The spray angle NA may be determined according to the diameter of the spray hole 1102 of the spray unit 1100, the exit angle (or inclination) of the spray hole 1102, the pressure of the coolant, and the like. For example, the spray angle NA may increase as the outlet angle of the spray hole 1102 increases and the pressure of the coolant increases.

In addition, the outlet angle of the injection unit 1100 may be between 0° and 60°. For example, an exit angle of the injection unit 1100 may be 0°.

In addition, the pressure in the cartridge (CTR) corresponding to the pressure of the coolant may be determined between 35 and 100 bar.

At this time, the spray angle NA may be determined between 20° and 70°.

The jetting distance ND may mean a distance from an end of the jetting unit 1100 .

The spray shape may be formed over the spray distance ND along a parabola formed by the spray angle NA.

The spraying shape may have a spraying area NS according to the spraying distance ND. The spraying area NS may mean an area corresponding to a plane perpendicular to the central axis of the spraying unit 1100 in the spraying form. In this case, the central axis of the injection unit 1100 may be understood to be the same as the central axis of the mixed module 1000 or the multifunctional module 100 . Referring to (a) of FIG. 14 , the spraying shape may include a first spraying area NS1 at a first spraying distance ND1 and a second spraying area NS2 at a second spraying distance ND2 .

15 is a view showing a process of mixing a coolant 1 and a composition 2 according to an embodiment of the present specification.

The coolant 1 may be sprayed from the ejection unit 1100 . The coolant 1 sprayed from the ejection unit 1100 may have a unique spray shape. Here, the spray form may be divided into at least a first section S1 and a second section S2 in consideration of the mixing space MA. For example, referring to FIG. 15 , the spraying form is a first section S1 and a mixing space MA having an aspect in which the coolant 1 spreads in a width direction (or a direction away from a central axis) of the mixing space MA. ) It can be divided into a second section (S2) having an aspect corresponding to.

The first section S1 is near the injection hole 1102 and may be understood as a section in which the coolant 1 begins to occupy the mixing space MA. In other words, the mixing space MA may not be saturated with the coolant 1 in the first section S1.

At any point in the first section S1, the area of the spray area NS may not correspond to the width of the mixing space MA. Alternatively, the area of the spray area NS at any point in the first section S1 may not correspond to the cross-sectional area perpendicular to the central axis of the mixing space MA. Alternatively, the width of the injection area NS may not correspond to the width of the mixing space MA at any point in the first section S1.

The second section S2 may be understood as a section after the first section S1 in the spraying direction in the mixing space MA. In the second section S2 , the mixing space MA may be saturated with the coolant 1 . In other words, in the second section S2 , the mixing space MA may be occupied by the coolant 1 .

The area of the injection area NS at any point in the second section S2 may correspond to the width of the mixing space MA. Alternatively, the area of the injection area NS at any point in the second section S2 may correspond to the cross-sectional area perpendicular to the central axis of the mixing space MA. Alternatively, the width of the injection area NS may correspond to the width of the mixing space MA at any point in the second section S2.

The first section may have a critical length (CL). The critical length CL may be determined based on at least the diameter of the spray hole 1102, the spray angle NA of the spray hole 1102, the outlet angle of the spray hole 1102, or the width of the mixing space MA. . For example, when the diameter of the spray hole 1102 is 0.15 mm, the exit angle of the spray hole 1102 is 0°, and the width of the mixing space MA is 8 mm, the critical length CL may be 9.5 mm. .

The critical length CL does not always have a specific value, and may have a different value according to specifications of components of the mixed injection system 10 as described above. The critical length CL may increase as the diameter of the injection hole 1102 increases. The critical length CL may be shortened as the injection angle NA increases. The critical length CL may be shortened as the exit angle of the injection hole 1102 increases. The threshold length CL may increase as the width of the mixing space MA increases.

As the coolant 1 is sprayed, negative pressure may be formed on at least a part of the inner diameter surface of the mixing space. As the coolant 1 having a certain speed moves near the inner diameter surface of the mixing space MA, a pressure lower than atmospheric pressure may be formed according to Bernoulli's principle. For example, referring to FIG. 15 , the coolant 1 may be injected at a constant speed along the inner circumferential surface of the mixing space MA in the second section S2 , and thus negative pressure may be formed.

Here, the inlet 2130 is fluidly connected to the mixing space MA as described above, and the other end 2132 of the inlet may be located on the inner diameter surface of the mixing space MA. For example, as shown in FIG. 15 , the other end 2132 of the inlet may be located at a portion corresponding to the second section S2 of the inner diameter surface of the mixing space MA. In this case, the first distance D1 from the end of the spraying part 1100 to the other end 2132 of the inlet may be equal to or greater than the critical length CL.

As the coolant 1 is injected, negative pressure may be formed at the other end 2132 of the inlet. Referring to FIG. 15, when negative pressure is formed at the other end 2132 of the inlet, the pressure inside the composition container 2220 is greater than the pressure at the other end 2132 of the inlet, so that outside air is introduced through the outside air inlet 2221. can As outside air is introduced through the outside air inlet 2221 , the composition 2 may move to the mixing space MA through the inlet 2130 and be mixed with the coolant 1 .

Meanwhile, depending on the position of the other end 2132 of the inlet in the mixing space MA, the composition 2 may not flow into the mixing space MA even if the coolant 1 is sprayed.

16 is a view showing a case where the coolant 1 and the composition 2 are not mixed according to an embodiment of the present specification. Referring to FIG. 16 , the other end 2132 of the inlet may be formed on the inner diameter surface of the mixing space MA corresponding to the first section S1. Alternatively, the first distance D1 from the end of the injection part 1100 to the other end 2132 of the inlet may be smaller than the critical length CL. In this case, even if the coolant 1 is sprayed from the injection unit 1100, negative pressure is not formed at the other end 2132 of the inlet unit, so the composition 2 may not flow into the mixing space MA through the inlet unit 2130. there is. In other words, since the coolant 1 does not move in the vicinity of the inner diameter surface of the mixing space MA corresponding to the first section S1 and, accordingly, negative pressure is not formed (or negligible negative pressure is formed), the other end of the inlet port The composition 2 may not move to the mixing space MA because a pressure difference does not occur between the 2132 and the inside of the composition container 2220 (or a pressure difference sufficient to move the composition 2 does not occur). (Alternatively, the composition (2) may migrate very slightly).

As described above, in order to mix the coolant 1 and the composition 2 in the mixing space MA, the position of the other end 2132 of the inlet in the mixing space MA may be very important. The other end 2132 of the inlet needs to be located in a portion corresponding to the second section S2 in the mixing space MA so that negative pressure is formed according to the injection of the coolant 1 at the other end 2132 of the inlet. Alternatively, the first distance D1 from the end of the injection part 1100 to the other end 2132 of the inlet part based on the central axis may be greater than or equal to the critical length CL of the first section S1.

For example, when the diameter of the spray hole 1102 is 0.15 mm, the outlet angle of the spray hole 1102 is 0°, and the width of the mixing space MA is 8 mm, the critical length CL is 9.5 mm, and the first The distance D1 may be greater than or equal to 9.5 mm.

In the above, the case where the other end 2132 of the inlet is located on the inner diameter surface of the mixing space MA has been described, but the other end 2132 of the inlet part is designed to protrude from the inner diameter surface of the mixing space MA in the direction of the central axis. It can be. In this case, the first distance D1 between the end of the injection part 1100 and the other end 2132 of the inlet is sufficient as long as the negative pressure is formed at the other end 2132 of the inlet according to the injection of the coolant 1, and must be a critical length. (CL) It doesn't have to be more than that. However, in this case, the other end 2132 of the inlet is cooled, so that the composition 2 does not flow into the mixing space MA or only a small amount may occur. Therefore, preferably, the other end 2132 of the inlet should be located on the inner diameter surface of the mixing space MA corresponding to the second section S2 in the spray form of the coolant 1.

Hereinafter, with reference to FIG. 17 , design conditions regarding the positional relationship between the mixing module 1000 of the complex function module 100 and the sensor unit 260 of the coolant supply device 200 among the configuration of the mixing injection system 10 are applied. describe about

FIG. 17 is a diagram illustrating a positional relationship between the mixing module 1000 of the complex function module 100 and the sensor unit 260 of the coolant supply device 200 according to an embodiment of the present specification.

First, the coolant supply device 200 may include the sensor unit 260 to measure the temperature of the target as described above, and the sensor unit 260 may include at least one sensor. Also, the sensor unit 260 may have a sensing area according to an angle of view (or a wide angle). For example, referring to FIG. 17 , the sensor unit 260 may include a first sensor 261 and a second sensor 262 . The first sensor 261 may have a first sensing area SA1 and the second sensor 262 may have a second sensing area SA2. The first sensor 261 and the second sensor 262 are arranged to have a preset angle so that the first sensing area SA1 and the second sensing area SA2 are the same at a specific distance from the coolant supply device 200. can have a center. In other words, when the target is located at a specific distance from the coolant supply device 200, the first sensor 261 and the second sensor 262 may be arranged to measure the temperature of the same part of the target.

Here, the range of the first sensing area SA1 is determined according to the angle of view (or wide angle) of the first sensor 261, and the range of the second sensing area SA2 is determined according to the angle of view (or wide angle) of the second sensor 262. ) can be determined according to

Furthermore, the first sensing area SA1 and the second sensing area SA2 may be determined according to distances between the first and second sensors 261 and 262 from the one end 1001 of the mixing module. Specifically, the first sensing area SA1 is an end of the first sensor 261 spaced apart from the mixing module end 1001 by the first separation distance DCS1, an inclination of the first sensor 261 with respect to a central axis, and the angle of view of the first sensor 261, and the second sensing area SA2 is an end of the second sensor 262 spaced apart from the one end of the mixing module 1001 by the second separation distance DCS1, and the central axis. It can be determined by the slope of the second sensor 262 and the angle of view of the second sensor 262 with respect to .

Since the coolant supply device 200 includes the first sensor 261 and the second sensor 262, more accurate temperature measurement is possible and precise temperature control is possible. However, the coolant supply device 200 may use one sensor.

The mixing module 1000 may have a certain length, and the mixing part 1200 of the mixing module 1000 may have a certain width. For example, referring to FIG. 17 , the mixing module 1000 may have a first length L1 and the mixing unit 1200 may have a first width W1. The first length L1 of the mixing module 1000 may be determined according to the length of the mixing unit 1200 and the length of the combining unit 1300 . The first width W1 of the mixing unit 1200 may correspond to an outer diameter of the mixing unit 1200 .

The mixing module 1000 may be designed not to interfere with the sensing area of the sensor unit 260 .

For example, as shown in FIG. 17 , the first length L1 of the mixing module 1000 and the first width W1 of the mixing unit 1200 are the first width W1 of the mixing module 1000 of the first sensor 261. It can be determined within a range that does not interfere with the first sensing area SA1 and the second sensing area SA2. Specifically, the first separation distance DCS1, the inclination of the first sensor 261 with respect to the central axis, the angle of view of the first sensor 261, the second separation distance DCS2, and the second sensor 262 with respect to the central axis ) and the angle of view of the second sensor 262, the first length L1 of the blending module 1000 and the first width W1 of the blending unit 1200 may be determined.

As another example, the first length L1 of the blending module 1000 and the first width W1 of the blending unit 1200 do not cover the sensing area of any one of the plurality of sensors included in the sensor unit 260. can be determined in Specifically, the first length L1 of the mixing module 1000 based on the first separation distance DCS1, the inclination of the first sensor 261 with respect to the central axis, and the angle of view of the first sensor 261, and A first width W1 of the mixing unit 1200 may be determined. Alternatively, the first length L1 of the mixing module 1000 based on the second separation distance DCS2, the inclination of the second sensor 262 with respect to the central axis, and the angle of view of the second sensor 262, and mixing A first width W1 of the portion 1200 may be determined.

In the above, the case where the sensor unit 260 includes two sensors has been described, but the technical spirit of the present specification is not limited thereto, and the case where the sensor unit 260 includes one sensor or three or more sensors Even when including , the first length L1 of the mixing module 1000 and the first width W1 of the mixing unit 1200 are values at which the mixing module 1000 does not interfere with the sensing area of the sensor unit 260. can be determined by

In the above, the design conditions of the length of the mixing module 1000 and the width of the mixing unit 1200 have been described, but the technical idea of the present specification is not limited thereto, and the composition supply module 2000 to the mixing module 1000 ) or the guide unit 3000 is coupled and affects the sensing area of the sensor unit 260, the value of a specific part of the composition supply module 2000 or the guide unit 3000 is the sensing area of the sensor unit 260 can be adjusted appropriately so as not to affect

[Another embodiment of the mixed injection system]

Hereinafter, another embodiment of the mixed injection system 10 will be described with reference to FIGS. 18 to 20 .

FIG. 18 is a view illustrating a case where an outside air inlet 2221 is formed in an adapter 2100 in the mixed injection system 10 according to an embodiment of the present specification.

As described above, in order for the composition 2 to move to the mixing space MA through the inlet 2130, the outside air must be introduced into the composition container 2200, and the outside air inlet 2221 is the outside air in the composition container 2200 ) can provide a flow path to move to.

The outside air inlet 2221 may be formed in the adapter 2100 . For example, referring to FIG. 18 , the adapter 2100 may include an outside air inlet 2221 fluidly connecting the outside and the composition container 2200 . As described above, when negative pressure is formed at the other end of the inlet 2132 according to the injection of the coolant 1, the composition 2 moves to the mixing space MA because one end of the outside air inlet 2221 corresponds to atmospheric pressure. can

Meanwhile, as shown in FIG. 18 , the mixing module 1000 and the adapter 2100 may be integrally implemented, and the adapter 2100 may be mounted on the mixing module 1000 as described above.

Also, as shown in FIG. 18 , at least a portion of the adapter 2100 may be coupled to the composition container 2200 to seal the composition container 2200 . At this time, the composition container 2200 includes a case 2210 in which the composition 2 is stored and a cover for sealing it, and after the cover of the composition container 2200 is removed in the operation of the mixing and spraying system 10 The case 2210 of the composition container 2200 may be coupled to the adapter 2100.

Alternatively, unlike that shown in FIG. 18, the mixing module 1000 includes an inlet 2130 and an outside air inlet 2221, and the composition container 2200 includes the inlet 2130 and the outside air inlet 2221. It can be coupled to the mixing module 1000 through. For example, a piercing member such as a needle is provided at one end of the inlet 2130 and one end of the outside air inlet 2221, respectively, and the composition container 2200 is formed by the inlet 2130 and the outside air inlet 2221. The composition container 2200 may be coupled to the mixing module 1000 while the cover of the composition container 2200 is perforated.

At this time, the mixing and spraying system 10 may include a support member for supporting the composition container 2200. For example, the holding member extends from the mixing module 1000 or the mixing unit 1200, and when the inlet 2130 and the outside air inlet 2221 and the composition container 2200 are connected, at least the composition container 2200 can support some

Here, the composition container 2200 may be a commercially available cosmetic product or medical product such as an ampoule, cosmetic product, or vial.

Even in the case of the mixed injection system 10 described with reference to FIG. 18, it goes without saying that the above-described design conditions of the mixed injection system 10 must be satisfied. For example, the distance from the end of the spraying part 1100 of the mixing module 1000 to the other end 2132 of the inlet is a critical length for forming negative pressure at the other end 2132 of the inlet according to the spray form of the coolant 1 ( CL) can be determined above. For another example, the length and width of the mixing unit 1200 may be determined within a range that does not block the sensing area of the sensor unit 260 .

Meanwhile, in the above, the case where the composition 2 is introduced into the mixing space MA by negative pressure formation and outside air has been described, but the composition 2 is also formed by another structure in which a pressure difference is formed according to the injection of the coolant 1 as follows. ) may flow into the mixing space MA.

19 is a cross-sectional view of a mixing module 1000 according to an embodiment of the present specification.

The mixing module 1000 may include an inlet 2130 and an auxiliary flow path 2150 for moving the composition 2 . Referring to FIG. 19 , the mixing module 1000 may include an inlet 2130 through which the composition 2 moves and an auxiliary flow path 2150 for generating a pressure difference.

One end of the auxiliary passage 2151 may be fluidly connected to the composition container 2200 and the other end 2152 of the auxiliary passage may be fluidly connected to the mixing space MA of the mixing unit 1200 .

Both the inlet 2130 and the auxiliary passage 2150 are connected to the mixing space MA, but the width of the mixing space MA to which the inlet 2130 is connected and the portion to which the auxiliary passage 2150 is connected may have different widths. For example, of the cross section of the mixing space MA perpendicular to the central axis, the area of the cross section corresponding to the other end 2131 of the inlet may be smaller than the area of the cross section corresponding to the other end 2152 of the auxiliary passage.

In other words, the mixing unit 1200 providing the mixing space MA may include a first part 1230 where the inlet 2130 is located and a second part 1240 where the auxiliary flow path 2150 is located. And, the inner diameter of the first part 1230 may be smaller than the inner diameter of the second part 1240 . Specifically, referring to (a) of FIG. 19, the mixing unit 1200 has a shape in which the inner diameter is constant and then gradually increases as the distance from the injection unit 1100 increases, and the first portion 1230 is a portion having a constant inner diameter. At least a portion, and the second portion 1240 may be at least a portion of a portion whose inner diameter gradually increases.

As the widths of the parts connected to the inlet 2130 and the auxiliary passage 2150 in the mixing space MA are different from each other, the coolant 1 is sprayed to form a pressure between the inlet 2130 and the auxiliary passage 2150. difference may occur. For example, the flow rate of the coolant 1 injected from the injection unit 1100 decreases as the width of the mixing space MA increases, so that the flow rate of the coolant 1 at the other end 2132 of the inlet is increased to the other end of the auxiliary passage 2152. is faster than the flow rate of the coolant 1 in , and the internal pressure of the inlet 2130 is lower than the internal pressure of the auxiliary flow path 2150 according to Bernoulli's equation, so that the composition 2 flows through the inlet 2130 into the mixing space.
