Description

The above-described objectives, features and advantages will become more apparent through the following detailed description in conjunction with the accompanying drawings. However, since the present invention can be subject to various changes and various embodiments, specific embodiments will be illustrated in the drawings and described in detail below.

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

Numbers (eg, first, second, etc.) used in the description of this specification are merely identifiers to distinguish one component from another component.

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

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

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

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

In cases where an embodiment can be implemented differently, a specific process sequence may be performed differently from the described sequence. For example, two processes described in succession may be performed substantially at the same time, or may be performed in an order opposite to that in which they are described.

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

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

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

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

This specification relates to a mixing module used in a coolant supply device. The purpose of the mixing module is to spray the coolant and the composition together by mixing the composition with the coolant supplied from the coolant supply device. When the coolant and the composition are mixed and sprayed onto the target, the composition at a relatively low temperature can be sprayed onto the target.

Here, the composition is a concept that encompasses not only pharmaceutical compositions used for medical treatment purposes but also cosmetic compositions used for cosmetic purposes, and may refer to substances containing active ingredients that induce or generate medical or cosmetic effects. .

Here, the coolants include carbon dioxide (CO2), liquid nitrogen (LN), nitrogen dioxide (NO2), nitrogen monoxide (NO), HFC (hydrofluorocarbon) series materials, methane (CH4), PFC, SF6, cooling water, cooling gas, etc. Any material capable of applying cooling energy to an area may be used.

Here, 'target' may mean a body part for which a cosmetic effect or medical effect is desired to be generated through a procedure, treatment, or care. For example, the target may refer to the skin. Below, for convenience of explanation, the case where the target is skin is mainly described, but the technical idea of the present specification is not limited to this.

The degree of penetration of the composition into the skin may be affected by the temperature of the skin. Specifically, when the temperature of the skin is lowered to a certain level, the skin cells shrink and the gaps between the cells become larger, and the composition penetrates through the gaps between the cells, resulting in improved penetration of the composition.

Meanwhile, various problems may occur when spraying a mixture of a coolant and a composition. For example, problems may occur where the composition is not sprayed uniformly due to agglomeration of the composition, problems where the composition is not uniformly distributed in the coolant spray area, and problems where the composition is frozen by the coolant.

Here, problems in which the composition is not sprayed uniformly due to agglomeration or the composition is not uniformly distributed in the coolant spray area may eventually cause a decrease in penetration power.

Specifically, in order for the composition to penetrate effectively, the composition needs to be sprayed with sufficiently strong force (or pressure). When the composition collides with the sprayed coolant (or receives the kinetic energy of the sprayed coolant) and is sprayed, if the size of the composition increases (or its mass increases), the speed at which the composition is sprayed may decrease according to the law of conservation of momentum. there is. In other words, the total amount of energy possessed by the sprayed coolant is shared by the composition sprayed together. In this case, the more the composition is divided into particles of uniform size, the more powerful it can be sprayed (or at a faster speed). Accordingly, penetration can be improved.

Also, here, the problem of the composition freezing due to the coolant may cause the mixing injection system or mixing module to not operate, or may cause the person receiving the treatment to feel uncomfortable.

In this specification, we will describe a mixing module with improved penetration and convenience by preventing the above-mentioned problems from occurring.

1. Mixed injection system

Below, before describing the mixing module, the mixing injection system and the aspects in which the mixing module is used in the mixing injection system will first be described with reference to FIGS. 1 and 2.

Figure 1 is a diagram showing a mixing injection system 100 according to an embodiment.

Referring to FIG. 1, the mixing injection system 100 may include a mixing module 1000 and a coolant supply device 2000.

First, the coolant supply device 2000 may refer to a device that supplies coolant. Specifically, the coolant supply device 2000 may supply coolant to the mixing module 1000. The coolant supply device 2000 may be referred to by various expressions such as a coolant injection device or an injection device.

The coolant supply device 2000 may store coolant internally or may receive coolant from a separate coolant storage means. For example, the coolant supply device 2000 may be coupled to a cartridge in which coolant is stored, and obtain coolant from the coupled cartridge, as will be described later. For another example, the coolant supply device 2000 may receive coolant from an external coolant reservoir through a hose.

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

The mixing module 1000 may receive coolant from the coolant supply device 2000.

Mixing module 1000 can store compositions. For example, the mixing module 1000 may include a container for storing the composition, as described below. Alternatively, the mixing module 1000 may receive the composition from outside.

The mixing module 1000 may provide a mixing space where the coolant and the composition are mixed. The method of mixing the coolant and the composition will be described later.

Figure 2 is a diagram showing a process in which the components of the mixing injection system 100 according to one embodiment are combined.

The mixing module 1000 may be attached or detached from the coolant supply device 2000. Specifically, the mixing module 1000 may be mounted on or separated from any component of the coolant supply device 2000.

Referring to FIG. 2, the coolant supply device 2000 includes a main body (MB), a coolant spray unit 2100 and a cartridge (CTR) coupled to the main body MB, and the mixing module 1000 includes a coolant spray unit ( 2100).

Furthermore, the mixed injection system 100 may further include a cover (COV) surrounding the coolant injection unit 2100. The cover (COV) may be coupled to the main body (MB) of the coolant supply device 2000.

Referring to FIG. 2 , the coolant spray unit 2100 and the cover (COV) are sequentially coupled to the main body MB, and then the mixing module 1000 may be coupled to the coolant spray unit 2100. The cover COV may form a space for the coolant spray unit 2100 to pass through. Accordingly, when the cover (COV) is coupled to the main body (MB), the coolant injection unit 2100 may penetrate the cover (COV).

In the mixed injection system 100, the cover (COV) may be omitted. Alternatively, in the mixing injection system 100, the cover (COV) may be implemented as a part of the mixing module 1000. Alternatively, in the mixed injection system 100, the cover (COV) may be implemented as a part of the coolant supply device 2000.

In the above, the case where the mixed injection system 100 is divided into a plurality of components and the divided components are combined or separated from each other has been described. In this way, the mixing module 1000 can be separated from the coolant supply device 2000, so the mixing module 1000 can be used for disposable purposes. Alternatively, the mixing module 1000 may be used one or more times and then cleaned and reused.

Meanwhile, the coolant injection unit 2100 and the mixing module 1000 of the mixing injection system 100 may be implemented as a physically connected body. Furthermore, in the mixing injection system 100, the mixing module 1000 and the coolant supply device 2000 may be implemented as a physically connected body. For example, the coolant injection unit 2100 may be configured as part of the mixing module 1000. For another example, the coolant spray unit 2100 and the mixing module 1000 may be configured as part of the coolant supply device 2000.

2. Coolant supply device

Hereinafter, the coolant supply device 2000 will be described with reference to FIG. 3.

FIG. 3 is a diagram showing the configuration of a coolant supply device 2000 according to an embodiment.

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

The coolant spray unit 2100 may include a structure for spraying coolant. Specifically, the coolant injection unit 2100 extends from one end to the other end to form a flow path, and may include a portion where the width of the flow path is relatively narrow. The fluid passing through the coolant injection unit 2100 expands as its pressure decreases as it passes through the narrow portion, and as a result, it can be sprayed at high speed. At this time, the fluid expands adiabatically while passing through the coolant spray unit 2100 and has a very low temperature. The temperature of the coolant can be controlled to a temperature suitable for surgery or treatment by the temperature control unit 2300, which will be described later.

The coolant injection unit 2100 may be understood as a nozzle. However, the technical idea of the present specification is not limited thereto, and the coolant injection unit 2100 may be understood as a configuration including a fluid movement passage in the form of an arbitrary tube.

The coolant spray unit 2100 may be attached or detached to the main body (MB) of the coolant supply device 2000. For example, the coolant injection unit 2100 may be coupled to or separated from the main body MB through the injection unit coupling part 2200. Alternatively, the coolant spray unit 2100 may be physically connected to the main body (MB) of the coolant supply device 2000 and integrated with it.

As described above, the mixing module 1000 may be coupled to the coolant injection unit 2100. To this end, the coolant spray unit 2100 and the mixing module 1000 may each include a coupling portion or coupling member.

Meanwhile, the mixing module 1000 may be designed in various forms as will be described later. Specifically, the mixing module 1000 may have a different structure depending on the type of composition to be used. As a result, the function or effect desired to be generated using the mixing injection system 100 may vary depending on the type of mixing module 1000 coupled to the coolant injection unit 2100.

The coolant injection unit 2100 may be coupled to the injection unit coupling unit 2200. On the other hand, when the coolant injection unit 2100 is omitted from the mixing injection system 100 or when the coolant injection unit 2100 becomes part of the mixing module 1000, the mixing module 1000 is included in the injection unit coupling unit 2200. These can also be combined.

A passage through which the coolant moves may be formed inside the injection unit coupling portion 2200. For example, the spray coupling unit 2200 includes an outlet hole, and the coolant may move to the coolant spray unit 2100 coupled to the jet coupling unit 2200 through the outlet hole.

The temperature control unit 2300 can control the temperature of the coolant. For example, the temperature control unit 2300 may increase the temperature of the coolant by providing heat energy to the coolant, and the temperature of the coolant may be adjusted according to the amount of heat energy provided by the temperature control unit 2300. The coolant injected through the coolant spray unit 2100 may have a relatively low temperature as described above, and in this case, the temperature of the coolant may vary depending on the heat energy provided by the temperature control unit 2300.

The temperature control unit 2300 may include a heat production unit that produces heat energy and a heat transfer unit that transfers the produced heat energy to a flow path through which the coolant moves. For example, the heat production unit may include an element that uses a thermoelectric effect such as Peltier's effect to produce heat energy according to the applied power.

The flow rate controller 2400 can control the movement of coolant. For example, the flow rate control unit 2400 includes a valve and can receive a signal from the control unit 2900 to open and close the valve. Depending on whether the valve is open or closed, the coolant may or may not move. The flow amount of coolant can be controlled depending on the degree of opening and closing of the valve.

The cartridge coupling portion 2500 can accommodate at least a portion of the above-described cartridge (CTR). Here, the cartridge (CTR) can be understood as a container that stores coolant. Specifically, the cartridge (CTR) can store coolant under a certain pressure, and the pressure can be determined between about 35 bar and 100 bar at 0 to 40 ° C. The pressure within the cartridge (CTR) may affect the injection amount of the coolant or the injection form of the coolant, and may indirectly affect the injection amount of the composition.

With the cartridge (CTR) coupled to the cartridge coupling portion 2500, the coolant stored in the cartridge (CTR) may move to the main body (MB).

The sensor unit 2600 can measure the temperature of the area where the coolant is sprayed. For example, the sensor unit 2600 may measure the temperature of the skin surface where the coolant is sprayed and provide measurement information to the control unit 2900.

The input unit 2700 may receive a user's input. For example, the input unit 2700 includes at least one push button switch and may provide a push input signal to the control unit 2900 according to the user's pressure of the switch, and the control unit 2900 may provide a push input signal to the control unit 2900. The opening and closing of the flow rate controller 2400 can be controlled based on the input signal. In addition, the input unit 2700 includes at least one rotary switch and can provide a rotation input signal to the control unit 2900 according to the user's operation, and the control unit 2900 provides a rotation input signal based on the rotation input signal. You can set the target cooling temperature or target cooling time. Here, the target cooling temperature may refer to the temperature at which the target to which the coolant is to be sprayed, for example, the skin surface, is to be cooled. Additionally, the target cooling time may refer to the time for which the injection of coolant must be maintained or the time that must elapse for the temperature of the skin surface to reach the target cooling temperature.

The output unit 2800 can output an interface for using the coolant supply device 200 and various information to the user. For example, the output unit 2800 may include a display, and output an interface for setting the target cooling temperature, target cooling time, etc. through the display, and while the coolant supply device 2000 is running, the sensor unit 2600 Information such as the real-time temperature of the measured skin surface or the total time the coolant was sprayed can be output.

The control unit 2900 can control the configurations of the coolant supply device 2000. For example, the control unit 2900 may control the temperature of the coolant by controlling the temperature control unit 2300, control the flow of the coolant by controlling the flow rate control unit 2400, and output unit 2800. You can output specific information to the user through .

Referring to FIG. 3, the coolant supply device 2000 may operate as follows.

The control unit 2900 may first set the target cooling temperature and/or target cooling time. The control unit 2900 provides an interface that guides the user to set the target cooling temperature and/or target cooling time through the output unit 2800, and receives a setting input signal according to the user's operation through the input unit 2700. The target cooling temperature and/or target cooling time may be set based on the received setting input signal.

Afterwards, the control unit 2900 outputs a message indicating to the user that operation preparation is complete through the output unit 2800, and receives a switch on input signal according to the user's operation through the input unit 2700. And, the coolant can be sprayed based on the received switch-on input signal.

While the coolant is injected, the control unit 2900 acquires a temperature value measuring the temperature of the target to which the coolant is injected through the sensor unit 2600, and compares the obtained temperature value with the set target cooling temperature to control the temperature control unit 2300. ) can be controlled. At this time, if the obtained temperature value is lower than the target cooling temperature, the control unit 2900 increases the heat energy applied to the coolant through the temperature control unit 2300, and if the obtained temperature value is higher than the target cooling temperature, the control unit 2900 increases the heat energy applied to the coolant through the temperature control unit 2300. Through (2300), the heat energy applied to the coolant can be reduced.

The coolant supply device 2000 is not limited to the above-described embodiment, and any device or structure that performs the function of supplying coolant can be viewed as the coolant supply device 2000 described in this specification.

For example, the coolant supply device 2000 may control the temperature of the coolant by continuously providing a certain amount of heat energy to the coolant without monitoring the temperature of the target. In this case, the step of setting or inputting the target cooling temperature can be omitted.

3. Mixing module

Hereinafter, the mixing module 1000 will be generally described with reference to FIGS. 4 to 6.

Figure 4 is a diagram showing the principle of mixing a coolant and a composition according to an embodiment.

First, as shown in (a) of FIG. 4, a tube-shaped mixing space may be provided with a coolant injection unit 2100 for spraying coolant and an inlet hole (IH) for introducing the composition.

The container in which the composition is stored and the inlet hole (IH) may be fluidly connected through a composition flow path. The composition flow path may be formed in a direction perpendicular to the central axis (CA) of the coolant spray unit 2100, but is not limited thereto.

Referring to (b) of FIG. 4, when the coolant is sprayed from the coolant spray unit 2100, the spray form of the coolant is divided into the main stream (MS) and the sub stream (SS) based on the central axis of the coolant spray unit 2100. It can be divided into:

The main stream (MS) may refer to an area where the coolant is sprayed relatively strongly, and the sub-stream (SS) may refer to an area where the coolant is sprayed relatively weakly.

In addition, the main stream (MS) is formed within a certain distance based on the central axis (CA) of the coolant injection unit 2100, and the sub-stream (SS) is formed within a certain distance based on the central axis (CA) of the coolant injection unit 2100. It can be formed outside a certain distance. However, the criteria for dividing the main stream (MS) and sub-stream (SS) are not limited to the above-mentioned criteria.

As will be described later, the composition flows into the main stream (MS) or sub-stream (SS) of the coolant due to the negative pressure formed by coolant injection and is mixed with the coolant, and the mixed coolant and the composition may be sprayed together. However, the force applied by the coolant to the composition in the main stream (MS) and sub-stream (SS) may be different.

The coolant sprayed from the coolant spray unit 2100 may pass near the inlet hole (IH). When coolant passes at a relatively high speed near the inlet hole (IH), negative pressure may be formed near the inlet hole (IH) according to Bernoulli's equation. Due to the negative pressure formed near the inlet hole (IH), the composition may flow into the mixing space through the inlet hole and be mixed with the coolant. Specifically, an external force such as atmospheric pressure may be continuously applied to the container in which the composition is stored, and it can be understood that this external force becomes greater than the negative pressure, causing the composition to move.

The composition flowing into the inlet hole (IH) collides with the coolant while mixing with the coolant, and as a result, the composition may be separated into finer particles and sprayed.

FIG. 5 is a diagram illustrating a mixing module 1000 according to an embodiment.

FIG. 6 is a cross-sectional view showing the mixing module 1000 coupled to the coolant injection unit 2100 according to an embodiment.

Referring to Figures 5 and 6, the mixing module 1000 includes a mixing part 1100, a composition inlet 1200, a composition storage part 1300, a cap 1400, and a fastening part 1500. It can be included.

The mixing unit 1100 may provide a mixing space 1110 where the coolant and the composition are mixed. Specifically, the inner surface of the mixing unit 1100 may define a mixing space 1110, and an inlet hole (IH) and an insertion hole (SH) may be formed on the inner surface of the mixing unit 1100. Meanwhile, when the coolant injection unit 2100 is configured as part of the mixing module 1000 or is omitted, the insertion hole SH may be omitted.

The mixing unit 1100 may include a mixture injection port 1120. The mixture injection hole 1120 can be understood as a boundary through which the coolant and composition are sprayed to the outside of the mixing module 1000.

The composition inlet 1200 refers to the part where the composition flows. Specifically, the composition inlet 1200 serves to fluidly connect the mixing space of the composition storage unit 1300, where the composition is stored, and the mixing unit 1100. To this end, the composition inlet 1200 may form a tube 1210 for moving the composition and the inlet hole (IH) described above.

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

Tube 1210 may have various shapes. For example, referring to FIG. 6 , the tube 1210 may be implemented in a form including a bent portion. More specifically, the tube 1210 may have a shape that bends in the distal direction. Here, the distal direction may be understood as the direction in which the coolant is sprayed or the direction from the first end 1100a to the second end 1100b of the mixing unit 1100. Alternatively, one end of the tube 1210 located within the composition storage unit 1300 may be located at a certain distance in the above-mentioned distal direction with respect to the central axis of the composition storage unit 1300. The shape of the tube 1210 causes the effect of allowing the composition stored in the composition storage unit 1300 to be used to the maximum, considering the usage mode of the mixing injection system 100. For example, when spraying a coolant and a composition using the mixed injection system 100 shown in FIG. 2, the spraying direction is generally from upward (in the direction opposite to gravity) to downward (in the direction of gravity), and in this case, the composition The composition within the reservoir 1300 may move distally (or anteriorly) by gravity. Therefore, in order to maximize the use of the composition in the composition storage unit 1300, one end of the tube 1210 needs to be located in the position where the composition moves, that is, in the space in front of the central axis of the composition storage unit 1300. .

The inlet hole (IH) may be formed on the inner surface of the mixing unit 1100. The inlet hole (IH) may have a cross section parallel to the central axis of the mixing unit 1100 on the inner surface of the mixing unit 1100.

The tube 1210 and the inlet hole (IH) may be understood as one body. For example, the inlet hole (IH) is a part of the tube 1210, and one end of the tube 1210 may be understood as the inlet hole (IH).

Alternatively, the tube 1210 and the inlet hole (IH) may be implemented as separate structures, and the tube 1210 may be coupled to the inlet hole (IH).

The composition storage unit 1300 may provide a space to accommodate the composition. The composition storage unit 1300 may provide a space to receive and store a composition from the outside.

The composition stored in the composition storage unit 1300 may move to the mixing unit 1100 through the composition inlet 1200.

Meanwhile, the composition can be continuously supplied to the mixing injection system 100 from the outside, and the composition storage unit 1300 is understood as a configuration that provides a space for the continuously supplied composition to stay before flowing into the mixing unit 1100. It could be.

The cap 1400 may be understood as a component that seals the composition storage unit 1300. At this time, the composition can be stored in the composition storage unit 1300 in the following manner. The user opens the cap 1400 coupled to the composition storage unit 1300, pours the composition contained in a separate composition container (e.g. an ampoule or cosmetic container, etc.) into the composition storage unit 1300, and closes the cap 1400. It can be closed.

The fastening part 1500 may be fastened to the coolant spraying part 2100. The fastening part 1500 may include a support part 1510 and an insertion hole (SH). The coolant injection unit 2100 may be inserted into the insertion hole (SH). The support portion 1510 may support the inserted coolant injection portion 2100. Each of the fastening part 1500 and the coolant spraying part 2100 may include members for fastening to each other. The process of fastening the fastening part 1500 and the coolant spraying part 2100 will be described later.

Referring to FIG. 5, the mixing module 1000 may include an external air passage (AP) and a handle.

The external air passage (AP) may be fluidly connected to the composition storage unit 1400. Due to the external air passage (AP), the pressure within the composition storage unit 1400 can be maintained at atmospheric pressure. Therefore, when negative pressure is formed in the inlet hole (IH), the pressure in the composition storage unit 1400 becomes larger, allowing the composition to move to the mixing unit 1100 through the composition inlet 1200.

The handle may be understood as a configuration that allows the mixing module 1000 to be easily separated from the coolant supply device 2000.

The above-described components of mixing module 1000 can be produced and assembled independently.

Alternatively, at least some of the above-described components of the mixing module 1000 may be formed integrally. For example, the mixing unit 1100, the composition storage unit 1300, and the fastening unit 1500 may be physically connected and produced as one body, and the separately produced tube 1210 and cap 1400 may be assembled. For another example, the mixing unit 1100, the composition storage unit 1300, and the tube 1210 may be produced as a physically connected body, and the cap 1400 may be produced and assembled separately.

Meanwhile, the mixing module 1000 may be implemented differently than described above. For example, the mixing module 1000 may include the components described above, but may include a container mounting unit instead of the composition storage unit 1300. The container mounting portion is a structure to which a composition container is coupled, and may have a structure including a needle capable of puncturing a stopper of a composition container or other structure to which a composition container can be coupled. The container mounting portion may be fluidly connected to the tube 1210 or the inlet hole (IH).

In this case, the user can use the mixing injection system 100 by coupling the composition container itself to the mixing module 1000, rather than pouring the composition into the composition storage unit 1300 of the mixing module 1000. .

Hereinafter, for convenience of explanation, the mixing module 1000 includes a mixing part 1100, a composition inlet 1200, a composition storage part 1300, a cap 1400, and a fastening part 1500. , the case where the composition is transferred from a separate composition container to the composition storage unit 1300 is mainly described, but the technical idea of the present specification is not limited to this.

Meanwhile, when using the mixing module 1000 described above, various problems may occur depending on the physical properties of the composition (e.g. viscosity, cohesion, freezing point, or adhesion, etc.). Below, various problems that may occur in the mixing module 1000 and their solutions (ex. design direction of the mixing module 1000) are described in detail.

4. Mixed module design

Below, with reference to FIG. 7, basic considerations and problems that may arise when designing the mixing module 1000 are described.

FIG. 7 is a diagram showing a pattern in which coolant is sprayed inside the mixing module 1000 according to an embodiment.

The purpose of the mixing module 1000 is to move the composition using coolant spray without a separate pressurizing device, and for this purpose, negative pressure according to the Bernoulli principle described above is used.

Referring to FIG. 7 , a spray stream of coolant may be formed inside the mixing unit 1100 of the mixing module 1000 as the coolant is sprayed. Here, in order for the composition to move from the composition storage unit 1300 to the mixing space 1110, negative pressure must be formed in the inlet hole (IH).

Here, in order for negative pressure to be formed in the inlet hole (IH), the spray stream must pass near the inlet hole (IH). At this time, whether the injection stream passes near the inlet hole (IH) depends on the size of the injection stream, the width of the mixing section 1100, and the distance between the coolant injection hole 2110 and the inlet hole (IH).

First, the size of the injection stream may mean the size of the cross section of the injection stream, particularly the size of the cross section perpendicular to the central axis (CA) of the coolant injection unit 2100 in the sub stream (SS). The cross-sectional size of the injection stream may increase with distance from the coolant injection opening 2110. Additionally, the size of the cross section of the jet stream may increase as the jet angle at the coolant jet port 2110 increases.

When the size of the cross section of the injection stream corresponds to the width of the mixing section 1100, a portion of the injection stream may be understood as being close to or in contact with the inner surface of the mixing section 1100. In other words, from a critical position that is a certain distance away from the coolant injection hole 2110 based on the direction in which the coolant is sprayed, the injection stream may be close to or in contact with the inner surface of the mixing section 1100.

In order for negative pressure to be formed by the spray stream in the inlet hole (IH) formed on the inner surface of the mixing unit 1100, the position of the inlet hole (IH) must be determined based on the above-described critical position. For example, the inlet hole (IH) may be formed at a critical position. For another example, the inlet hole IH may be formed within a certain distance in the distal direction (coolant injection direction) based on the critical position. For another example, the inlet hole IH may be formed within a certain distance in the proximal direction (opposite the direction of injection of the coolant) based on the critical position.

Meanwhile, in the vicinity of the coolant injection hole 2110, the size of the injection stream is relatively small compared to the width of the mixing section 1100, so the injection stream may not be formed on the inner surface of the mixing section 1100. Therefore, the inlet hole (IH) needs to be formed at a certain distance away from the coolant injection hole 2110 in the distal direction (coolant injection direction).

4.1. Problem #1 that occurs and solution

Meanwhile, as described above, the injection stream may be divided into a main stream (MS) and a sub-stream (SS), and the injection speed of the coolant may be different in the main stream (MS) and the sub-stream (SS). Specifically, the movement speed of the coolant in the main stream (MS) is greater than the movement speed of the coolant in the sub-stream (SS).

A pressure difference may exist between partial regions within the mixing unit 1100 due to differences in the movement speed of the coolant in each region. For example, referring to FIG. 7 , a relatively low air pressure may be formed around the coolant injection hole 2110 through which the coolant moves relatively quickly within the mixing unit 1100.

More specifically, when the coolant is injected, according to Bernoulli's theorem, a first air pressure is formed at the first low pressure point (P1) near the inlet hole (IH), and a first air pressure is formed at the second low pressure point (P2) near the coolant injection hole (2110). A pressure of 2 atmospheres can be formed.

At this time, since the moving speed of the coolant at the coolant injection port 2110 is faster than the moving speed of the coolant near the inlet hole (IH), the second air pressure at the second low pressure point (P2) is the first low pressure point ( It may be lower than the first atmospheric pressure at P1). In other words, the composition flowing into the inlet hole (IH) is forced to move to the second low pressure point (P2) where a second air pressure lower than the first air pressure is formed.

Meanwhile, the force applied by the spray stream to the composition introduced through the inlet hole (IH) may vary depending on the area. For example, the force applied by the coolant to the composition in the sub-stream (SS) may be smaller than the force applied by the coolant to the composition in the main stream (MS). Furthermore, the force affecting the movement of the composition in the sub-stream (SS) may be greater than the force caused by the coolant due to the external force formed by the difference in first and second air pressures.

For this reason, in order for the composition introduced into the mixing section 1100 to be sprayed together with the coolant, it is desirable to move to the main stream (MS) of the coolant. In addition, the composition that cannot move to the main stream (MS) may move in the direction opposite to the injection direction of the coolant or toward the second air pressure point (P2) due to the air pressure difference rather than being sprayed by the sub stream (SS). .

Compositions that have moved near the second pressure point P2 or the coolant injection port 2110 may aggregate with each other depending on their physical properties. The agglomerated composition can be sprayed with a coolant in a relatively large volume, and thus compositions having different particle sizes can be sprayed from the mixing module 1000. Such non-uniform spraying of the composition may impede the penetration effect of the composition into the target and further cause discomfort to the subject (or the person receiving the treatment).

In order to solve the above-described problem, a structure or device is needed to guide the composition to reach the main stream (MS). Alternatively, a structure or device that prevents the composition from moving to the second low pressure point (P2) may be utilized.

Hereinafter, the structure of the mixing module 1000 to solve the above-mentioned problems will be described with reference to FIGS. 8 and 9.

FIG. 8 is a diagram illustrating a mixing module 1000 including a blocking member (BM) according to an embodiment.

Referring to FIG. 8 , a blocking member BM may be formed on the inner surface of the mixing unit 1100 of the mixing module 1000. The blocking member BM may prevent the composition from moving to the coolant injection port 2110 or the second end 1100b of the mixing unit 1100.

The blocking member BM may include a blocking surface BS.

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

The composition flowing in through the inlet hole (IH) may climb up the blocking surface (BS) of the blocking member (BM) and reach the main stream (MS) of the coolant. As a result, the composition may not move to the second low pressure point (P2) near the coolant injection port 2110.

The blocking surface BS may have a preset blocking angle with respect to the inlet hole IH. For example, the blocking surface BS may have a preset first angle with respect to a virtual plane including the cross section of the inlet hole IH. Here, the preset blocking angle can be determined from 0° to 90° or less. The blocking surface BS may be a flat surface, a curved surface, or a combination thereof.

The blocking member BM may have a preset blocking height BH. The blocking height (BH) may refer to the height of the blocking member (BM) in a direction perpendicular to the central axis of the mixing unit 1100 with respect to the inlet hole (IH).

The cutoff height (BM) can be set to the height of the main stream (MS) of coolant. For example, when the width of the main stream MS is 1/2 the width of the mixing section 1100, the cutoff height may be determined at 1/2 or less of the width of the mixing section 1100.

The blocking member BM may be produced integrally with the mixing unit 1100. Specifically, the blocking member BM may have a shape that protrudes from the inner surface of the mixing unit 1100.

The blocking member BM may be produced separately from the mixing unit 1100 and coupled to the inner surface of the mixing unit 1100.

On the other hand, when using a blocking member (BM) to block the aggregation of the composition, the composition used for mixing and spraying needs to have a relatively low adhesion force. Here, the adhesion force can be understood as an attractive force between the blocking member (BM) and the composition. Therefore, when a composition with high adhesion is used, the composition may pass over the blocking surface (BS) of the blocking member (BM), and as a result, agglomeration may occur at the second low pressure point (P2).

Additionally, when using a blocking member (BM), the composition used for mixing spraying needs to have a relatively high freezing point. This is because the temperature of the blocking member (BM) may be lowered by the injected coolant, and as a result, the temperature of the composition rising on the blocking member (BM) may also be lowered, causing a problem in which the composition is sprayed in a frozen state.

FIG. 9 is a diagram illustrating a mixing module 1000 including an inclined member (IM) according to an embodiment.

The area where the above-described composition can aggregate in the mixing section 1100 of the mixing module 1000 may be filled. Referring to FIG. 9, the mixing module 1000 may include an inclined member (IM).

An inclined member (IM) may be understood as a block with an incline, a ramp, or a ramp. The inclined member IM may be disposed between the inlet hole IH and the coolant injection hole 2110.

The inclined member (IM) may include an inclined surface (INS). The inclined surface (INS) may be implemented as a flat surface, a curved surface, or a combination thereof.

The inclined surface (INS) may be in contact with a portion of the composition inlet 1200. For example, the inclined surface INS may be in contact with the inlet hole IH or may extend from the inlet hole IH.

The inclined surface (INS) may extend from the composition inlet 1200 to the vicinity of the coolant injection port 2110. For example, the inclined surface INS may be in contact with the coolant injection hole 2110.

The inclined surface (INS) can be designed considering the spray form of the coolant. For example, the inclined surface (INS) may be designed to correspond to the shape of the main stream (MS).

Alternatively, the inclined surface (INS) may be implemented in a form having an inclination of a certain angle.

The inclined member IM may be created integrally with the mixing unit 1100. Specifically, the inclined member IM may be understood as a portion of the inner surface of the mixing unit 1100 that has an inclination.

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

The composition flowing into the inlet hole (IH) may go up the inclined surface (INS) of the inclined member (IM), and may be sprayed by the main stream (MS) of the coolant in the process of going up. As a result, the composition can be sprayed by the coolant before it agglomerates.

On the other hand, when using an inclined member (IM), the composition used for spraying needs to have a relatively high freezing point. This is because the temperature of the inclined member (IM) may be lowered by the injected coolant, and as a result, the temperature of the composition rising on the inclined member (IM) may also be lowered, causing a problem of the frozen composition being sprayed.

4.2. Occurring problem #2 and solution

As described above, when the mixing module 1000 is designed to allow the composition to reach the main stream (MS) of the coolant, the composition may be prevented from agglomerating, but a phenomenon may occur in which the composition is not uniformly mixed with the coolant.

Specifically, as shown in FIG. 10, when a blocking member (BM) is used in the mixing module 1000, the composition is The spray may be biased towards a portion (ex. lower part) of the main stream (MS) of the coolant.

If the goal is to spray the composition evenly distributed throughout the main stream (MS) of the coolant rather than spraying it more intensively in one area, it is necessary to prevent the above phenomenon from occurring.

In order to solve the above-described problem, it is necessary to induce the composition to move beyond reaching the bottom of the coolant main stream (MS) to the top of the main stream (MS).

To this end, the mixing module 1000 may include a guide member. The guide member provides a surface on which the composition can travel, and may be implemented in a shape that allows the composition to move up to the top of the main stream (MS).

Specifically, the guide member may be implemented in a form that surrounds at least a portion of the injected coolant. For example, the guide member may be implemented in a form that surrounds at least a portion of the main stream (MS). In this case, the guide member can spread the composition to the top of the main stream (MS) without interfering with the injection of the coolant.

Hereinafter, various embodiments of the guide member will be described with reference to FIGS. 11 to 19. Meanwhile, it should be noted in advance that the guide member may be referred to in various ways, such as a guide plate, spreading film, metal film, spreading plate, heat exchange inducing member, heat transfer member, or insert, depending on its shape or function.

FIG. 11 is a diagram illustrating a guide plate 1610 according to an embodiment.

Figure 12 is a diagram showing a process in which a composition moves through a guide plate 1610 according to an embodiment.

FIG. 13 is a diagram showing the shape of the guide plate 1610 and the first plate 1611 of the guide plate 1610 based on the mixing unit 1100 according to an embodiment.

The guide plate 1610 may be disposed in the mixing unit 1100 of the mixing module 1000 to induce movement of the composition. Hereinafter, the guide plate 1610 is described as being produced separately from the mixing unit 1100 and coupled to the mixing unit 1100. However, the technical idea of the present specification is not limited to this, and the guide plate 1610 may be implemented in a state where it is physically integrated with the mixing unit 1100.

The guide plate 1610 can be understood as a structure composed of multiple surfaces. For example, referring to FIG. 11 , the guide plate 1610 may include a first plate 1611 and a second plate 1612. At this time, the expression of the first and second plates 1611 and 1612 is a word used to refer to one component of the guide plate 1610, such as the first and second parts, the first and second frames, or the first and second plates. It may also be expressed as 1 and 2 structures, etc.

The first plate 1611 may include at least a first plate surface (S11) and a second plate surface (S12).

Here, the first plate surface S11 may refer to a surface in contact with the inside of the mixing unit 1100 when the first plate 1611 is disposed in the mixing unit 1100. Specifically, the first plate 1611 is disposed adjacent to the inlet hole (IH) as shown in FIG. 11, and at this time, the first plate surface (S11) may contact the inner surface of the mixing unit 1100. The first plate surface S11 and the inner surface of the mixing unit 1100 may be in surface contact or line contact.

The second plate surface S12 refers to a surface that is inclined by a preset angle with respect to the inlet hole IH when the first plate 1611 is placed in the mixing unit 1100. In other words, the second plate surface S12 may have a preset angle with respect to the plane including the inlet hole IH. At this time, the first plate surface (S11) and the second plate surface (S12) may have a specific angle between them. The composition flowing in through the inlet hole (IH) can move along the second plate surface (S12) due to the adhesion force with the second plate surface (S12).

The first plate surface S11 and the second plate surface S12 may be flat, curved, or a combination thereof.

The first plate surface (S11) and the second plate surface (S12) may be connected directly or indirectly.

The first plate surface S11 and the second plate surface S12 may meet each other. In other words, the first plate surface S11 and the second plate surface S12 may be in contact with each other or may share one side.

The first plate surface S11 and the second plate surface S12 may not meet each other, and in this case, an additional surface may be located between the first plate surface S11 and the second plate surface S12. At this time, the plane including the first plate surface S11 and the plane including the second plate surface S12 may meet or be parallel to each other.

The first plate 1611 may include additional surfaces in addition to the above-described first plate surface S11 and second plate surface S12.

The first plate 1611 may be implemented in various shapes. For example, the first plate 1611 may be implemented as bent or folded at a certain angle, as shown in FIG. 11 . For another example, the first plate 1611 may be implemented in various shapes, such as a rectangular parallelepiped shape or a shape with a curved surface.

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

Here, the third plate surface S13 may refer to a surface in contact with the inside of the mixing unit 1100 when the second plate 1612 is disposed in the mixing unit 1100. Specifically, the second plate 1612 is disposed adjacent to the inlet hole (IH) as shown in FIG. 11, and at this time, the third plate surface (S13) may contact the inner surface of the mixing unit 1100. The third plate surface S13 and the inner surface of the mixing unit 1100 may be in surface contact or line contact.

The fourth plate surface S14 refers to a surface that is inclined by a preset angle with respect to the inlet hole IH when the second plate 1612 is placed in the mixing unit 1100. In other words, the fourth plate surface S14 may have a preset angle with respect to the plane including the inlet hole IH. At this time, the third plate surface S13 and the fourth plate surface S14 may have a specific angle between them. The composition flowing in through the inlet hole (IH) can move along the fourth plate surface (S14) due to the adhesion force with the fourth plate surface (S14).

The third plate surface S13 and the fourth plate surface S14 may be flat, curved, or a combination thereof.

The third plate surface S13 and the fourth plate surface S14 may be connected directly or indirectly.

The third plate surface S13 and the fourth plate surface S14 may meet each other. In other words, the third plate surface S13 and the fourth plate surface S14 may be in contact with each other or may share one side.

The third plate surface S13 and the fourth plate surface S14 may not meet each other, and in this case, an additional surface may exist between the third plate surface S13 and the fourth plate surface S14. At this time, the plane including the third plate surface S13 and the plane including the fourth plate surface S14 may meet or be parallel to each other.

The second plate 1612 may include additional surfaces in addition to the above-described third plate surface S13 and fourth plate surface S14.

The second plate 1612 may be implemented in various shapes. For example, the second plate 1612 may be implemented as bent or folded at a certain angle, as shown in FIG. 11 . For another example, the second plate 1612 may be implemented in various shapes, such as a rectangular parallelepiped shape or a shape with a curved surface.

The first plate 1611 and the second plate 1612 may be arranged to have a specific positional relationship inside the mixing unit 1100. For example, referring to (a) of FIG. 11 or FIG. 12 , the first plate 1611 and the second plate 1612 may be arranged to be spaced apart from each other. At this time, the inlet hole (IH) may be located between the first plate 1611 and the second plate 1612.

The first plate 1611 and the second plate 1612 may be symmetrically disposed inside the mixing unit 1100.

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

Referring to FIG. 13, the composition flowing in from the inlet hole (IH) can move along the guide plate 1610. The composition moving along the guide plate 1610 may be mixed with the main stream (MS) of the coolant and sprayed. As will be described later, if the height of the guide plate 1610 is sufficiently large, the composition can reach the top of the main stream (MS). Accordingly, the composition is mixed with the coolant not only at the bottom but also at the top of the main stream (MS), and as a result, the composition can be evenly distributed in the main stream (MS).

As described above, in order for the composition moving on the guide plate 1610 to reach the top of the main stream (MS), the guide plate 1610 needs to be designed to have a specific size.

Referring to (a) of FIG. 13, the guide plate 1610 may be designed to have a certain height, a certain distance, and a certain inclination angle.

The height of the guide plate 1610 may refer to the height when placed in the mixing unit 1100. For example, the first plate 1611 may have a first height H1 in a direction perpendicular to the central axis of the mixing unit 1100 with respect to the inlet hole IH. Additionally, the second plate 1612 may have a second height H2 in a direction perpendicular to the central axis of the mixing unit 1100 with respect to the inlet hole IH.

The distance of the guide plate 1610 may refer to the distance from the center of the mixing unit 1100 when placed in the mixing unit 1100. For example, the first plate 1611 may have a first distance D1 from the central axis of the mixing unit 1100. At this time, the first distance D1 may be understood as the shortest distance from the central axis of the mixing unit 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 unit 1100.

The inclination angle of the guide plate 1610 may refer to the angle with respect to the inlet hole (IH) when disposed in the mixing unit 1100. For example, the second plate surface S12 of the first plate 1611 may have a first inclination angle IA1 based on the surface including the inlet hole IH or a surface parallel to the inlet hole IH. there is. Additionally, the second plate 1612 may also have a second inclination angle IA2.

Referring to (b) of FIG. 13, the guide plate 1610 may be designed to have a certain length.

The length of the guide plate 1610 may be defined in a direction parallel to the central axis of the mixing unit 1100. For example, as shown in (b) of FIG. 13, 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 is understood as the length of a straight line connecting a point of the first plate stage 1611a and a point of the second plate stage 1611b among straight lines parallel to the central axis of the mixing unit 1100. It can be. The second plate 1612 also extends from the third plate end to the fourth plate end and may have a second length.

The height and distance of the guide plate 1610 may be designed based on the internal structure of the mixing unit 1100. However, it is assumed that the mixing unit 1100 has a third height (H3) based on the inlet hole (IH) and a preset width (W). Additionally, it is assumed that the central axis of the mixing unit 1100 is the same as the central axis CA of the coolant spraying unit 2100.

The height of the guide plate 1610 is preferably designed to be more than half the height of the mixing unit 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 more than half the third height H3 of the mixing unit 1100. there is. This is to enable the composition to reach the top of the main stream (MS) of the coolant, as described above.

The distance of the guide plate 1610 is preferably designed to be more than 1/4 of the width (W) of the mixing section. For example, the first distance D1 of the first plate 1611 and/or the second distance D2 of the second plate 1612 may be more than 1/4 of the width W of the mixing section. This means that the width of the guide plate 1610 is determined according to the first distance D1 and the second distance D2, and the width of the guide plate 1610 is excessively narrow, so that the cross section of the main stream MS of the coolant is This is because if the size is smaller than the maximum size, coolant injection may be impaired, and furthermore, the temperature of the coolant inside the guide plate 1610 may decrease, causing the composition to freeze.

The inclination angle of the guide plate 1610 can be determined between 0° and 90°. For example, the first inclination angle IA1 formed between the second plate surface S12 of the first plate 1611 and 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, and the first plate surface (S11) and the second plate surface (S12) There is a need to provide more space in between. The second inclination angle IA2 of the second plate 1612 may also be designed similarly.

The length of the guide plate 1610 may be shorter than the length inside the mixing unit 1100, but is not limited thereto. For 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 unit 1100. The length of the guide plate 1610 may be greater than or equal to a certain value in consideration of the extent to which the composition flowing in from the inlet hole (IH) spreads.

Meanwhile, when using the guide plate 1610, the composition used 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 coolant, and as a result, the temperature of the composition rising on the guide plate 1610 may also be lowered, causing a problem in which the frozen composition is sprayed.

Figure 14 is a diagram showing a spreading film 1620 according to one embodiment.

Referring to FIG. 14, the spreading film 1620 extends from the first film end 1620a to the second film end 1620b and may include an inner surface (IS) and an outer surface (OS).

The spreading film 1620 can be attached and detached to the mixing unit 1100 of the mixing module 1000. Alternatively, the spreading film 1620 may be implemented integrally with the mixing unit 1100 so that the spreading film 1620 may form a part of the mixing unit 1100.

The spreading film 1620 may be produced by bending or curved a plate, but is not limited thereto.

The outer surface (OS) of the spreading film 1620 may include a contact portion. The contact portion refers to a portion that contacts the inner surface of the mixing portion 1100 when the spreading film 1620 is mounted on the mixing portion 1100.

The contact portion of the spreading film 1620 may include the first film surface S21. The first film surface S21 may be understood to have the same configuration as the first plate surface S11 of the guide plate 1610 described above. For example, when the spreading film 1620 is disposed adjacent to the inlet hole (IH), the first film surface (S21) may contact the inner surface of the mixing portion (1100). The first film surface S21 and the inner surface of the mixing unit 1100 may be in surface contact or line contact.

The inner surface (IS) of the spreading film 1620 may include an inclined portion. The inclined portion may refer to the portion where the composition moves. The outer surface (OS) and the inner surface (IS) of the spreading film 1620 may face each other.

The inclined portion of the spreading film 1620 may include a second film surface S22. The second film surface S22 is a surface inclined at a preset angle with respect to the inlet hole IH when the spreading film 1620 is placed in the mixing unit 1100, and is understood as a surface that induces movement of the composition. It can be. In other words, the second film surface S22 may have a preset angle with respect to the plane including the inlet hole IH. At this time, the first film surface S21 and the second film surface S22 may have a specific angle between them.

The first film surface S21 and the second film surface S22 may be connected directly or indirectly.

The first film surface S21 and the second film surface S22 may meet each other. In other words, the first film surface S21 and the second film surface S22 may be in contact with each other or may share one side.

The first film surface S21 and the second film surface S22 may not meet each other, and in this case, an additional surface may exist between the first film surface S21 and the second film surface S22. At this time, the plane including the first film surface S21 and the plane including the second film surface S22 may meet or be parallel to each other. Alternatively, the first film surface S21 and the second film surface S22 may face each other.

Spreading film 1620 may include a third film side and a fourth film side. The explanation of the first film surface (S21) can be applied equally to the third film surface, and the explanation of the second film surface (S22) can be equally applied to the fourth film surface. However, with respect to the central axis of the spreading film 1620, the first film surface and the third film surface may be symmetrical to each other, and the second film surface and the fourth film surface may be symmetrical to each other.

The composition flowing in through the inlet hole (IH) can move along the inner surface (IS) due to the adhesive force with the inner surface (IS).

The outer surface (OS) of the spreading film 1620 may be composed of one curved surface, multiple flat surfaces, multiple curved surfaces, or a combination thereof. Likewise, the inner surface IS of the spreading film 1620 may be composed of one curved surface, multiple flat surfaces, multiple curved surfaces, or a combination thereof.

Figure 15 is a view showing the front of the spreading film 1620 according to one embodiment.

Referring to FIG. 15, the spreading film 1620 may be divided into a first part 1621, a second part 1622, and a third part 1623. The first to third parts 1621, 1622, and 1623 refer to a part of the spreading film 1620 for convenience of explanation, such as the first to third plates, first to third frames, or It may also be referred to as first to third structures, etc.

The first part 1621 and the second part 1622 may be understood as respectively corresponding to the first plate 1611 and the second plate 1612 of the guide plate 1610 described above. Specifically, the first part 1621 and the second part 1622 may be positioned with an inlet hole (IH) between them, and the composition flowing in from the inlet hole (IH) may be disposed in the first part 1621 or the second part 1622. Portion 1622 may travel to the main stream (MS) of coolant.

Unlike the guide plate 1610, the spreading film 1620 may further include a third part 1623 connecting the first part 1621 and the second part 1622. In other words, the first to third parts 1621, 1622, and 1623 may be physically formed as one body.

The third portion 1623 may have an arch shape. The third portion 1623 may be composed of one curved surface, multiple flat surfaces, multiple curved surfaces, or a combination thereof.

As described below, third portion 1623 may cause the composition to be more uniformly mixed into the spray stream of coolant.

Figure 16 is a diagram showing a process in which a composition moves through a spreading film 1620 according to one embodiment.

Referring to FIG. 16, the composition flowing in from the inlet hole (IH) travels through the first part (1621) to reach the third part (1623) or moves along the second part (1622) to reach the third part (1623). ) can be reached.

Additionally, the composition moves 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). Thus, the spreading film 1620 can be rotated based on its central axis. Rotating the composition allows the composition to be more uniformly distributed in the spray stream of coolant.

Furthermore, the third portion 1623 may prevent the composition from migrating out of the main stream (MS) of the coolant.

Spreading film 1620 can be manufactured by bending a flat plate as described above. For example, the spreading film 1620 can be manufactured through preparing a square plate having first and second sides facing each other and bending the square plate so that the first and second sides face each other. there is. At this time, the first side and the second side may constitute the outer surface (OS) and may be included in the contact portion.

Meanwhile, when the spreading film 1620 is manufactured as described above, a gap is formed between the first part 1621 and the second part 1622 of the spreading film 1620, as shown in FIG. 14. This can be formed. If the spreading film 1620 is manufactured by injecting metal, etc. into a specific shape, the first part 1621 and the second part 1622 are directly connected, so a gap may not be created. .

Additionally, referring again to FIG. 14, the spreading film 1620 may include an inlet groove and a fastening groove (CG).

The inlet groove is a groove corresponding to the inlet hole (IH) and may include a first inlet groove (IG1) formed in the first part (1621) and a second inlet groove (IG1) formed in the second part (1622).

The spreading film 1620 may be fastened to the inside of the mixing unit 1100 through the fastening groove CG. A connection member (ex. hook member) corresponding to the fastening groove CG may be formed inside the mixing unit 1100. The fastening groove CG may be formed in the third portion 1623 of the spreading film 1620, but is not limited thereto.

Spreading film 1620 may have a preset radius of curvature.

FIG. 17 is a diagram showing the radius of curvature (CR) of the spreading film 1620 according to one embodiment. Referring to FIG. 17 , a portion of the inner surface (IS) of the spreading film 1620 may have a radius of curvature (CR). The radius of curvature (CR) may be understood as the radius of curvature (CR) of a portion of the inner surface (IS) of the spreading film 1620 corresponding to the third portion 1623.

The radius of curvature (CR) may be designed to be smaller than the width (W) of the mixing section, but equal to or larger than 1/4 of the width (W). However, if the cross section of the mixing unit 1100 is oval rather than circular, it may be designed differently, and may be determined through experiment with the purpose of corresponding to the maximum cross section size of the main stream (MS) of the coolant.

For example, for the mixing unit 1100 that provides a specific type of mixing space, the spot size of the coolant sprayed from the mixing module 1000 while changing the radius of curvature (CR), whether the composition is frozen, etc. An experiment to observe is conducted, and the optimal value of the radius of curvature (CR) can be determined through the experiment.

Spreading film 1620 may have a film width (FW). The film width (FW) can be understood as the maximum width of the spreading film 1620 in the horizontal direction. For example, the film width (FW) may be twice the radius of curvature (CR).

Meanwhile, the spreading film 1620 may have a certain length. The length of the spreading film 1620 may be understood to be the same as the first length L1 of the guide plate 1610 described above.

Figure 18 is a diagram showing a spreading film 1620 according to another embodiment.

The cross section of the spreading film 1620 may be implemented in a keyhole shape. Specifically, as shown in FIG. 18, the first portion 1621 of the spreading film 1620 is substantially perpendicular to the first film surface S21 in contact with the inlet hole IH and the cross section of the inlet hole IH. It may include a second film surface (S22). Likewise, the second portion 1622 of the spreading film 1620 has a third film surface S23 in contact with the inlet hole IH and a fourth film surface S24 substantially perpendicular to the cross section of the inlet hole IH. may include.

In addition to this, the spreading film 1620 may have various shapes. For example, the spreading film 1620 may have a shape that becomes narrower or larger as it moves from the first film end 1620a to the second film end 1620b. Additionally, the cross-sectional shape of the spreading film 1620 may be implemented in various ways, such as a circular shape, an oval shape, a polygonal shape, or a shape consisting of a combination of straight lines and curves.

Figure 19 is a diagram showing various forms of a guide member according to one embodiment.

Referring to (a) of FIG. 19, the guide wall 1630 may protrude from the inner surface of the mixing unit 1100. Specifically, guide walls 1630 may be formed on both sides of the inlet hole IH, and the surface of the guide wall 1630 is the second plate surface S12 of the above-described first plate 1611. and the fourth plate surface S14 of the second plate 1612. At this time, the height of the guide wall 1630 based on the inlet hole IH needs to be designed to be more than 1/2 of the second height H2 of the mixing unit 1100.

Referring to (b) of FIG. 19, 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 so that there is no gap between the first plate 1611 and the second plate 1612. A hole corresponding to the inlet hole (IH) may be formed in the third plate 1613. The guide plate 1610 further includes a third plate 1613, so that the composition flowing in through the inlet hole (IH) can move to the first plate 1611 or the second plate 1612 through the third plate 1613. It becomes possible. In other words, there is an advantage that the composition can be directed to the main stream (MS) of the coolant along the guide plate 1610 not only in the lateral direction but also in the entire direction.

4.3. Problem #3 that occurs and solution

It has been previously introduced that when the freezing point of the composition is relatively high, the frozen composition can be sprayed because the temperature of the main stream (MS) of the coolant is relatively low.

In order to solve the problem of the composition freezing, a method of increasing the temperature by applying heat to the mixing unit 1100 or directly increasing the temperature of the composition may be considered. However, these methods may impede the cooling effect of the coolant or require an additional heating device, which may cause a decrease in product quality or an increase in manufacturing cost.

Hereinafter, with reference to FIGS. 20 to 23, the design direction of the mixing module 1000 that prevents the composition from freezing without impairing the cooling effect as much as possible and without using a separate device will be described.

The basic principles are as follows. The space inside the mixing section 1100 is separated into an area corresponding to the main stream (MS) of the coolant and other areas, and outdoor air with a relatively high temperature compared to the coolant is continuously circulated through the separated areas to prevent the composition from freezing. This can be prevented.

Figure 20 is a diagram showing a spreading film 1620 provided with ventilation holes (VH) according to an embodiment.

FIG. 21 is a diagram illustrating a process in which external air is introduced and circulated in the mixing module 1000 according to an embodiment.

FIG. 22 is a cross-sectional view of the mixing unit 1100 equipped with the spreading film 1620 according to an embodiment.

As shown in FIG. 20, the spreading film 1620 previously described in FIG. 14 is used, and ventilation holes (VH) may be formed in the spreading film 1620.

Referring to FIG. 21, when the spreading film 1620 is mounted on the mixing unit 1100, the internal space of the mixing unit 1100 is divided into the first area A1 inside the spreading film 1620 and the spreading film ( 1620) It can be divided into an outer second area (A2). Here, the first area A1 can be viewed as an area where the main stream MS of the coolant is located. As the coolant is injected, the overall air pressure inside the mixing section 1100 decreases, so air outside the mixing section 1100 enters the mixing section 1100. At this time, since the coolant is being sprayed in the first area (A1), outdoor air may flow into the second area (A2) rather than the first area (A1), as shown in (a) of FIG. 21.

As shown in (b) of FIG. 21, external air flowing into the second area A2 may move to the ventilation hole VH formed in the spreading film 1620. This means that the closer the ventilation hole (VH) is formed to the first film end (1620a) of the spreading film (1620), the more outside air can move into the mixing section (1100) or near the coolant injection port (2110). .

Afterwards, outside air may flow into the first area A1 through the ventilation hole VH, and as a result, it may be discharged to the outside of the mixing unit 1100 along with the coolant.

In other words, due to the ventilation holes (VH) formed in the spreading film 1620, outdoor air with a relatively high temperature compared to the coolant continuously flows from the second area (A2) to the ventilation holes (VH) to the first area (A1). It can be circulated, and the circulated outdoor air can provide heat to the spreading film 1620 by passing through the outer surface (OS) of the spreading film 1620.

The spreading film 1620 can receive heat from external air and transfer heat to the composition moving along the spreading film 1620. The composition can receive heat and be sprayed in a non-frozen state.

Referring again to FIG. 20, the ventilation hole VH may be formed closer to the first film end 1620a than the second film end 1620b of the spreading film 1620. Furthermore, the ventilation hole VH may be formed closer to the first film end 1620a than between the first film end 1620a and the second film end 1620b of the spreading film 1620. As a result, the outside air can be discharged after moving to the inside of the mixing unit 1100, and thus the spreading film 1620 can receive heat from the outside air as a whole.

Referring to FIG. 22, when the spreading film 1620 is mounted on the mixing unit 1100, the ventilation hole VH is located at the first end 1100a rather than the second end 1100b of the mixing unit 1100. It can be located close by. Alternatively, the ventilation hole (VH) may be located between the inlet hole (IH) and the first end (1100a). Alternatively, the ventilation hole (VH) may be located between the inlet hole (IH) and the first end (1100a), but may be located closer to the first end (1100a) than the inlet hole (IH).

Ventilation holes (VH) may be formed on the left and right sides of the spreading film 1620, respectively. Alternatively, the ventilation hole (VH) may be formed only on either the left or right side of the spreading film 1620.

The ventilation hole (VH) can be implemented in various shapes. For example, the ventilation hole (VH) may have a circular, polygonal, or oval shape.

As described above, in order for the spreading film 1620 to receive heat from the outside air and transfer the received heat to the composition, the thermal conductivity of the spreading film 1620 needs to be above a certain value.

In the case of thermal conductivity, as a result of experiments using various metals, freezing of the composition did not occur in the case of copper (Cu), aluminum (Al), and SUS (Steel Use Stainless). Therefore, according to one example, the spreading film 1620 may be made of copper (Cu), aluminum (Al), and SUS, or a combination thereof. Additionally, according to 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 of 12 W/m·K or more.

In addition, for smooth heat transfer of the spreading film 1620, the thickness of the spreading film 1620 also needs to be below a certain value. For example, the thickness of the spreading film 1620 may be about 1.0 mm or less. Preferably, the thickness of the spreading film 1620 may be 0.5 mm or less. More preferably, the thickness of the spreading film 1620 may be about 0.3 mm.

Meanwhile, circulation of external air can be induced even if the ventilation hole (VH) is not formed in the spreading film 1620.

FIG. 23 is a diagram illustrating a state in which the spreading film 1620 is disposed in the mixing unit 1100 so that a gap is formed between the spreading film 1620 and the coolant injection hole 2110 according to an embodiment.

Referring to FIG. 23, the spreading film 1620 may be disposed in the mixing section 1100 so that a gap is formed between the first film end 1620a of the spreading film 1620 and the coolant injection hole 2110. For example, when the spreading film 1620 is disposed in the mixing section 1100, the first film end 1620a of the spreading film 1620 is directed distally from the coolant injection opening 2110 (e.g., the coolant injection direction). ) can be separated by a preset distance. Alternatively, the first film end 1620a may be spaced apart from the first end 1100a of the mixing unit 1100 by a preset distance in the distal direction.

Meanwhile, the shape of the first film stage 1620a of the spreading film 1620 is such that when the spreading film 1620 is placed in the mixing section 1100, it is between the spreading film 1620 and the first stage 1100a. It may be designed to form a space.

At this time, the length of the spreading film 1620 may be shorter than the length of the mixing unit 1100, but is not limited thereto.

A gap or space formed between the spreading film 1620 and the first end 1100a of the mixing unit 1100 or the coolant injection hole 2110 may serve as the ventilation hole VH described above.

4.4. Selective use of guide members

As described above, the guide member can solve problems that may occur when mixing and spraying a coolant and a composition in the mixed spray system 100.

The shape of the guide member to solve a certain problem may vary, and a guide member of the required shape may be used (e.g., mounted on the mixing module 1000 or implemented integrally) depending on the physical properties of the composition. For example, if the viscosity or cohesion of the composition is relatively low and the freezing point is relatively low, the guide member may not be used. For another example, when the viscosity or cohesion of the composition is high and the freezing point is relatively low, a guide plate 1610, a spreading film 1620, or a spreading film 1620 with ventilation holes (VH) may be used. there is. For another example, when the freezing point of the composition is relatively high, a spreading film 1620 with ventilation holes (VH) may be used.

5. Connection of mixing module and coolant supply

Hereinafter, the process of combining the mixing module 1000 and the coolant supply device 2000 and the necessary configuration will be described with reference to FIGS. 24 and 25. In addition, with reference to FIG. 26, the configuration for mounting the guide member to the mixing module 1000 will be described.

FIG. 24 is a diagram illustrating a process in which the mixing module 1000 is mounted on the coolant spray unit 2100 according to an embodiment.

Referring to FIG. 24 , the mixing module 1000 may include a first fastening member 1520, and the coolant spray unit 2100 may include a second fastening member 2130.

The first fastening member 1520 may be formed in the fastening part 1500 of the mixing module 1000. The first fastening member 1520 may be a hook member. Alternatively, the first fastening member 1520 may include a locking protrusion.

The second fastening member 2130 may be formed on the outer surface of the coolant injection unit 2100. The second fastening member 2130 may include a groove or a hole.

The first fastening member 1520 of the mixing module 1000 and the second fastening member 2130 of the coolant spray unit 2100 may be coupled to each other. For example, when the coolant injection unit 2100 is inserted into the mixing module 1000 in a sliding manner, the engaging portion of the first fastening member 1520 may be caught in the groove of the second fastening member 2130.

The coolant injection unit 2100 may include an O-ring (2120). The O-ring 2120 allows the coolant spray unit 2100 and the mixing module 1000 to be more strongly coupled and may perform a sealing role as will be described later. The O-ring 2120 may be located between the coolant injection hole 2110 and the second fastening member 2130. Accordingly, the mixing module 1000 can be prevented from being indiscriminately separated from the coolant spray unit 2100.

FIG. 25 is a diagram illustrating a sealing process when the mixing module 1000 is coupled to the coolant spray unit 2100 according to an embodiment.

Referring to FIG. 25, when the coolant injection unit 2100 is inserted into the mixing module 1000, the front portion of the coolant injection unit 2100 (part including the coolant injection port 2110) is inserted into the insertion hole of the support portion 1510. The support portion 1510 may support the coolant injection hole 2110 while being inserted into (SH).

Meanwhile, when the coolant is injected from the coolant injection unit 2100, some of the coolant within the mixing unit 1100 may travel in a direction opposite to the direction in which the coolant is sprayed. The support unit 1510 may prevent the retrograde coolant from reaching the coolant spray unit 2100.

Additionally, referring to (b) of FIG. 25, the O-ring 2120 of the coolant spray unit 2100 can prevent outside air from flowing into the gap between the mixing module 1000 and the coolant spray unit 2100.

As described above, the support part 1510 and the O-ring 2120 can improve the stability of the connection between the mixing module 1000 and the coolant injection unit 2100 by reducing the risk of retrograde coolant or external air inflow.

FIG. 26 is a diagram showing a configuration for mounting a guide member to the mixing module 1000 according to an embodiment. Hereinafter, a case where the guide member is the spreading film 1620 will be described, but the technical idea of the present specification is not limited to this.

The mixing module 1000 may include at least one protruding portion. For example, referring to FIG. 26 , the inside of the mixing unit 1100 may include first to fifth protruding portions 1131, 1132, 1133, 1134, and 1135.

The protruding part can be understood as a configuration that performs the function of supporting a specific object, such as a rib or rail.

The protruding portion may support the spreading film 1620. Specifically, the protruding portion may support the spreading film 1620 so that it does not shake within the mixing unit 1100. For example, when the spreading film 1620 is mounted on the mixing module 1000, the first protruding portion 1131 supports the first portion 1621 of the spreading film 1620, and the second to second protruding portions 1131 support the first portion 1621 of the spreading film 1620. Four protruding portions 1132, 1133, 1134 support the third portion 1623 of the spreading film 1620, and the fifth protruding portion 1135 supports the second portion 1622 of the spreading film 1620. I can support it.

The protruding portion may be designed to correspond to the shape of the spreading film 1620.

The plurality of protruding portions may be formed symmetrically with respect to the central axis of the mixing unit 1100, but are not limited thereto.

The protruding portion may have a specific length inside the mixing unit 1100 in a direction parallel to the central axis of the mixing unit 1100. The length of the protruding portion may be shorter than the length of the inside of the mixing unit 1100.

6. Mixing module design considering injection volume

As described above, in the mixed injection system 100, the composition moves due to the formation of negative pressure due to the injection of the coolant. As a result, the spray amount of the composition depends in part on the spray amount of the coolant.

In this situation, if the amount of the composition or the injection amount of the composition and the amount of the coolant or the injection amount of the coolant are not precisely controlled, only the coolant is sprayed due to a lack of the composition, or a fixed amount of the composition (e.g., one treatment or one time) is sprayed due to a lack of the coolant. There may be cases where not all of the composition (amount of composition required for treatment, etc.) is sprayed.

In other words, when designing a device that sprays a coolant and a composition together, the time for which a specific amount of composition (e.g. ampoule capacity) is consumed and the time for a specific amount of coolant (e.g. cartridge capacity) to be consumed are substantially the same. The ‘condition of equal consumption time’ must be satisfied.

Figure 27 is a diagram showing a mixing module 1000 in which factors affecting the amount of composition sprayed according to one embodiment are displayed.

Referring to FIG. 27, the time for which the composition is consumed and the time for which the coolant is consumed are determined by the capacity of the coolant cartridge (CTR), coolant pressure (ex. internal pressure of the cartridge (CTR)), the size of the coolant nozzle 2110, and the mixing part. It may be affected by the width (W), the width of the guide member (ex. film width (FW)), the tube width (TW) of the tube 1210, and the physical properties of the composition (ex. composition viscosity).

Hereinafter, for convenience of explanation, the case where the guide member is the spreading film 1620 will be described, but the technical idea of the present specification is not limited to this.

After specifying the values of factors that are difficult to adjust among the influencing factors described above, the values of the factors that can be adjusted can be designed by considering the values of the specified factors and the 'same time consumption condition'.

First, the type of composition can be specified. The type of composition may be specified depending on the type of procedure or treatment provided. Since it is difficult to arbitrarily change the provided treatment, the type of composition is also difficult to change, and the physical properties of the composition, such as viscosity, can also be viewed as specified values.

Additionally, the amount of the composition is determined depending on the type of procedure or treatment provided or the type of composition container sold on the market, and the amount of coolant is determined depending on the capacity of the cartridge (CTR). Therefore, the amount of composition and the amount of coolant are not easy to arbitrarily adjust and can be viewed as specified values.

Next, the width (W) of the mixing section can be designed. The width (W) of the mixing module 1000 may be determined by considering the size of the coolant supply device 2000, the size of the coolant spray unit 2100 or the coolant spray port 2110, and/or the spray amount of the composition. For example, as the coolant supply device 2000 or the coolant nozzle 2110 becomes larger, the width (W) of the mixing section may increase. Meanwhile, as the width (W) of the mixing section increases, the spray amount of the composition may increase, and the width (W) of the mixing section can be readjusted later.

The film width (FW) of the spreading film 1620 can be designed considering the width (W) of the designed mixing section. The spreading film 1620 is preferably in a shape that surrounds the main stream (MS) of the coolant. The size of the main stream (MS) of the coolant varies depending on the size of the coolant nozzle 2110, and the film width (FW) is It can be designed considering the size of the coolant nozzle 2110.

Finally, the tube width (TW) can be designed. Here, it can be considered that the larger the tube width (TW), the larger the amount of composition sprayed.

In order to design the mixing module 1000 that satisfies the condition of equal consumption time, an experiment can be conducted by setting some of the above-mentioned variables as independent variables and changing the independent variables while monitoring whether the equal consumption time condition is satisfied.

The mixing module 1000 or the spreading film 1620 can be designed using the values of the variables calculated from the conducted experiment.

For example, the cartridge (CTR) capacity, coolant pressure, size of the coolant nozzle 2110, width of the mixing section (W), and film width (FW) are fixed to specific values, and the type of composition and the required amount of use of the composition are determined. By changing the tube width (TW), it is possible to monitor whether the consumption time of the coolant and the consumption time of the composition become substantially the same, and calculate the value of the tube width (TW) when the consumption time equal condition is satisfied. there is.

The mixing module 1000 may be designed to have a calculated tube width (TW) value and a specified mixing section width (W), and the spreading film 1620 may be designed to have a specified film width (FW). It can be.

As another example, the cartridge (CTR) capacity, coolant pressure, size of the coolant nozzle 2110, width of the mixing section (W), and tube width (TW) are fixed to specific values, and the type of composition and the required amount of use of the composition are determined. By changing the film width (FW), it is possible to monitor whether the consumption time of the coolant and the consumption time of the composition are substantially the same, and calculate the value of the film width (FW) when the consumption time equal condition is satisfied. there is.

The spreading film 1620 can be designed to have a calculated film width (FW), and the mixing module 1000 can be designed to have a specified tube width (TW) and mixing zone width (W).
