Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to an apparatus for manufacturing a cosmetic composition in which an emulsifying agent is added to an instant emulsified emulsified material using a microfluidic channel,

The present invention relates to an apparatus for manufacturing a cosmetic composition for discharging an emulsified material manufactured by instantaneous emulsification of an external fluid and an internal fluid moving along a microfluidic channel, By adding a very small amount of a thickening agent to emulsified materials such as O / W emulsified particles or W / O emulsified particles manufactured by a method of instantaneous emulsification using specific fluid behavior characteristics of the cosmetic composition, .

In general, the technique of emulsifying a fluid means a technique of dispersing one of two fluids, which do not mix with each other like water and oil, into small particles and dispersing them in a stable state in another liquid. In the field of cosmetics, emulsifying technology has been widely applied to lotions, creams, essences, massage creams, cleansing creams, makeup bases, foundations, eyeliners, and mascara. That is, in order to manufacture the above-described cosmetics, it is preferable to prepare oil-in-water (O / W) emulsified particles by uniformly dispersing a hydrophobic fluid such as oil in a hydrophilic fluid such as water in a small particle state, W / O (Water in Oil) emulsified particles are produced by uniformly dispersing the particles in a small particle state. Such O / W emulsion particles and W / O emulsion particles are called emulsions or emulsions.

In order to produce such an emulsified material, an emulsified material using a hydrophilic fluid and a hydrophobic fluid was prepared by a physical method. For example, as disclosed in Korean Patent Publication No. 10-0222000, conventionally, after a hydrophilic fluid and a hydrophobic fluid are both poured into a huge container, a stirrer is operated to disperse particles of another fluid to one fluid. For example, a homomixer or a microfluidizer is used as the stirrer. In other words, O / W emulsified particles or W / O emulsified particles were prepared by pouring a hydrophilic fluid and a hydrophobic fluid in a large vessel and then mixing the fluids with each other using a stirrer.

In addition to the above operations, by introducing the surfactant into the container, the interface energy between the hydrophilic fluid and the hydrophobic fluid is lowered to easily form an emulsion such as O / W emulsified particles or W / O emulsified particles, Thereby preventing aggregation of emulsified particles. Specifically, even if an emulsion such as O / W emulsified particles or W / O emulsified particles is formed by the operation of the stirrer, if the operation of the stirrer is stopped and a certain period of time is elapsed, the emulsion is united and the hydrophilic fluid and the hydrophobic fluid are separated . In order to prevent this phenomenon, that is, the surfactant is injected so that the emulsified tiny particles are stable and maintain the emulsion state for a long period of time.

In addition, the flowability of the emulsified material is lowered to prevent coalescence and separation, and an additional thickener is added to the container to improve the viscosity of the cosmetic. As the thickener is injected into the container, the long-term stability of the product is ensured and the viscosity of the product is improved, so that the skin can be improved in spreadability.

According to the above conventional art, a hydrophilic fluid and a hydrophobic fluid are put into a container, and after the emulsification is advanced, an increasing agent is added and mixed together by a stirrer. However, in the instant emulsification method using the microfluidic channel, when the extracorporeal fluid is added in an increasing state, the fluidity of the hydrophilic fluid and the hydrophobic fluid is lowered due to the thickening agent, and the formation of the emulsified material is not smoothly performed . In other words, since the thickening agent is a factor affecting the movement speed of the hydrophilic fluid and the hydrophobic fluid and the formation of the emulsified particles, it is necessary to pay careful attention to the injection timing. However, conventionally, .

In manufacturing a cosmetic composition containing an emulsifying material, since a large amount of emulsifying material is prepared in advance and the manufactured product must be sold in accordance with the demand of the user, a long period A blank period is generated. As a result, there has been a problem that a thickener, which is a chemical material, must be used more than necessary.

In addition, when a large amount of emulsified material is stored for a long period of time, there are problems in that various restrictions are caused in manufacturing, packaging, transportation, etc. in consideration of long-term stability of the product.

Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings. Although the present invention has been described with reference to the embodiments shown in the drawings, it is to be understood that the technical idea of the present invention and its essential structure and action are not limited by this embodiment.

FIG. 1 is a perspective view showing an apparatus for manufacturing a cosmetic composition containing an emulsifying agent according to an embodiment of the present invention. FIG. 2 is a plan view showing the configuration of the first channel among the fluid channels of the apparatus, and FIG. 3 is a plan view showing a configuration of the second channel stacked on the first channel of the fluid channels of the apparatus.

Referring to the drawings, an apparatus 1 for manufacturing a cosmetic composition according to the present invention is formed by a housing 10 in its outer shape. At one side of the housing 10, a pump 70 which can be operated by the user can be provided. That is, the user can pressurize the pump 70 to discharge the materials in the housing 10 to the outside. For example, when the user presses the pump 70, the pressure of the moving path of the substances in the housing 10 becomes high. In this state, when the user releases the pressure of the pump 70, negative pressure is applied to the movement path of the substances, thereby discharging the substances to the outside.

The pump 70 is a means for supplying energy for discharging the fluid from the containers 21, 22 and 45 to instantaneously emulsify the fluid and discharging the fluid through the discharge port formed on the outer side of the housing 10, An operating portion which can be operated by a user is exposed to the outside of the housing 10 and a connecting portion for discharging the mixed liquid to the outside can be provided inside the housing 10. [ The raw material contained in the outer container 21, the inner container 22 and the thickener container 45 is supplied to the fluid channel 100 by the pressure formed by the pump 70, The supplied raw materials move along a predetermined path and are instantaneously emulsified and then discharged to the pump 70 through the tube 60. To this end, a series of flow paths communicating with each other from the pump 70 to the respective containers 21, 22, 45 can be formed.

In the present embodiment, the pump 70 is configured to include a discharge unit that is exposed to the outside of the housing 10 to discharge cosmetics, but this is merely an example, and the spirit of the present invention is not limited thereto. For example, the discharge portion is provided separately from the pump 70, and the pump 70 may be connected to any point in the series of flow paths from the vessels 21, 22, 45 to the discharge portion to provide pressure have.

In this embodiment, the pump 70 is shown as an example of a push-type pump for allowing a negative pressure to be applied to the movement path of the fluids in the housing 10 by the user pressing and releasing the operating portion. In this case, the raw material discharge from the containers 21, 22 and 45, the movement in the fluid channel 100, and the discharge of the cosmetic material are both realized by the pressure in the single direction formed by the pump 70 There is an advantage that the configuration of the apparatus can be simplified.

However, the idea of the present invention is not limited to this, and various types of pumps may be used as the pump 70. [ For example, the non-powered pump may be a button-spring pump, a syringe pump, a flexible tube pump, a gear pump, a porous pump, a thread inserting pump, etc. Or a pump for absorbing or discharging the fluid by capillary action by applying an orifice, a rollerball, a pencil, or the like to the discharge port can be applied. As the power pump, a pump that controls electricity, vibration, sound waves, and a piezoelectric material to absorb or discharge fluid may be applied.

Inside the housing 10, there are provided a trauma container 21 in which an external fluid is contained and an internal container 22 in which an internal fluid is received. For example, the outer container 21 and the inner container 22 may be provided inside the housing 10 to form one fluid storage portion 20. Specifically, a shielding film 23 extending in the up-and-down direction and separating the inner space of the fluid accommodating portion 20 is provided at the center of the fluid accommodating portion 20. On one side of the shielding film 23, an external-phase fluid is received to form the external-phase container 21, and on the other side, an internal-phase fluid is accommodated to form an internal-

In addition, in the housing 10, an incremental container 45, which is separate from the fluid accommodating portion 20, is provided. The thickener may be stored in the thickener container 45.

If a neutralizing agent needs to be added depending on the acidity of the thickening agent, a neutralizing agent may be added to the external fluid contained in the container 21. That is, an emulsion may be produced in which the inner fluid and the emulsified particles are formed in the state where the neutralizing agent is added to the external fluid, and then the external fluid and the emulsified particles are sequentially contacted and agitated.

The outer container (21) and the inner container (22) are respectively connected to an outer fluid infusion pipe (30) and an inner fluid infusion pipe (40), which are movement paths of the inner and outer fluid stored therein. That is, the contaminant fluid contained in the container 21 can be discharged to the outside of the container 21 along the container 30. Similarly, the inner fluid contained in the inner container 22 may be discharged out of the inner container 22 along the inner fluid injection pipe 40.

In addition, the incremental container 45 is connected to the incremental injection pipe 46, which is the path of the incremental agent stored therein. That is, the thickener accommodated in the thickener vessel 45 may be discharged out of the thickener vessel 45 along the thickener inlet pipe 46.

In the present invention, a microfluidic channel 100 using a single sound pressure is applied instead of a conventional syringe pump using a positive pressure as an apparatus for producing a cosmetic composition. That is, according to the present invention, since a single sound pressure is applied to the microfluidic channel 100 as a discharge method of the emulsified material, the apparatus according to the present invention can be directly applied to a general cosmetic container and a pump structure.

Conventionally, it has been difficult to form and maintain emulsified particles without using an excess amount of surfactant (1% to 5%) because the interfacial tension between the external fluid and the internal fluid is high and they are not easily mixed with each other. However, according to the present embodiment, since the influence of the surface force on the fluid is much greater than the body force in the microfluidic channel 50 having the very small characteristic length (less than a millimeter), the surfactant, It is advantageous that the emulsifying action can be performed quickly by not using or adding a minimum amount. Also, the principle that any one of two fluids that do not easily mix with each other breaks off the flow of another fluid to form emulsified particles, also helps to reduce the surfactant.

Although the emulsification method using the microfluidic channel 100 has many advantages as described above, it is difficult to apply it to a cosmetic manufacturing apparatus because the production speed is limited as compared with existing emulsification apparatuses using a large tank and a stirrer. In order to solve the problem of the production speed, the present invention develops a microfluidic channel 100 applicable to a container, and employs a momentary emulsification method capable of emulsifying the microfluidic channel 100 at a desired time point based on a discharge amount.

The outer fluid infusion tube 30 and the inner fluid infusion tube 40 are connected to the first channel 50 of the fluid channel 100 at one side thereof. The fluid channel 100 may be formed on the bottom surface of the housing 10, for example, in the form of a flow passage for moving the fluid. However, the mounting position and shape of the fluid channel 100 are not limited thereto.

In this case, when the pressure is applied to the connecting portions of the containers 21, 22, 45 and the flow paths 30, 40, 46, Means may be provided.

The fluid channel 100 also includes a first channel 50 that constitutes the bottom and a second channel 80 that is stacked on top of the first channel 50. Although the first channel 50 is stacked on the second channel 80 in the present embodiment, the concept of the present invention is not limited thereto. For example, the first channel 50 may be stacked on the bottom of the second channel 80, or may be provided on the same plane. When the second channel 80 is stacked on the lower side of the first channel 80, the overall flow path can be configured to be relatively short, and the configuration of the apparatus can be simplified. In addition, when the first channel 50 and the second channel 80 are provided on the same plane, the first emulsified material passage 59 and the second emulsified material passage 81 may be the same.

First, the first channel 50 may be provided with injection ports communicating with the outer fluid injection tube 30 and the inner fluid injection tube 40. That is, the first channel 50 is an inlet passage for the inner fluid moved along the inner fluid injection tube 40 and the outer fluid injection port 51, which is an inlet path for the outer fluid flowing along the outer fluid injection tube 30, And an inner fluid injection port 54.

The outer fluid flowing into the first channel 50 through the outer fluid injection port 51 may be divided into a first branch tube 52 and a second branch tube 53 and may be moved to the downstream side toward the pump 70 . In the present specification, the term "downstream" means a direction in which the fluid stored in the fluid storage portion 20 is discharged to the outside through the tube 60 via the pump 70 by a user's pump operation.

Similarly, the inner fluid that has flowed into the first channel 50 through the inner fluid injection port 54 may be moved to the downstream side along the inner fluid moving tube 55. The external fluid moved along the first branch tube (52) and the second branch tube (53) and the internal fluid moved along the internal fluid moving tube (55) meet each other at the joint portion (56). That is, the joint portion 56 means the point where the foreign body and the internal fluid first meet in the housing 10.

The extracorporeal fluid and the inner fluid reached at the joint portion 56 pass through the emulsification portion 58 and become an emulsion, that is, an emulsified material. In the present embodiment, an orifice 58 having a relatively narrower width than that of the joint portion 56 is provided as the emulsification portion 58. [ The outer surface fluid and the inner fluid that are encountered at the joint portion 56 pass through the orifice 58 and flow in the direction of the resultant fluid in the flow direction (horizontal direction) of the fluid (the direction perpendicular to the inner side of the orifice 58) 58), the shear force acts on the inner fluid in the diagonal direction to cut off the flow of the inner fluid, thereby forming an emulsified material. Specifically, the two fluids that do not mix with each other increase the capillary instability when passing through the orifice 58 in an unstable interface state, and the channel with the orifice 58 has less energy than the channel without the fluid, The flow can be broken, and the interrupted fluid thus formed is formed into a spherical shape in order to maintain a stable state.

The emulsification portion 58 is formed by interrupting the flow of the mixed fluid and dispersing the mixed fluid in the particle-like state in the particle state. In the present embodiment, the orifice is provided as the emulsification portion 58 , But the spirit of the present invention is not limited thereto. Specifically, the emulsification method using the same orifice as in the present embodiment can be referred to as a flow-focusing method emulsification. This allows the fluid of different phases to flow in the same direction, but the orifice is positioned at the merging portion, (Flow-focusing method). When the orifice is used, the flow of the extraneous fluid changes diagonally inside the orifice, and a stronger shear force can be transmitted to the mixed fluid, so that the emulsion particle can be formed more easily and emulsion particles of a certain size can be formed .

In addition, various embodiments may be applied to the emulsification portion 58. For example, a method of emulsifying the fluids of different phases in the same direction while moving them in the same direction (Co-Flow method) (Cross-flow method), a method of forming emulsion particles in the joint portion by adjusting the aspect ratio of the entry port of the extracorporeal fluid into the entrainer and the entrances of the entrainer fluid to the joint portion (step emulsification method) Or a method of forming an emulsion particle by passing a mixed fluid of two phases through a hole of a membrane (Membrane Emulsification method) may be used.

The emulsification unit 58 may use a power source such as an electric control, a magnetic control, a centrifugal control, an optical control, a vibration control, a piezoelectric material A channel in which emulsified particles are formed using a piezoelectric control or the like may be used.

In addition, the emulsification portion 58 may form emulsion particles by changing the viscosity of the fluid, the interfacial tension, and the wettability. For example, the emulsion 58 may be formed of Electrorheological (ER) or Magnetorheological (MR) fluids, Fluids may be applied.

The emulsified material passing through the orifice 58 moves along the emulsified material moving pipe 57. Refers to the direction opposite to the direction of movement of the fluid by the pump operation of the user as the opposite direction of the "downstream ", i.e., the direction in which the pump 70, the tube 60, the fluid channel 100, Means a direction toward the accommodating portion 20.

Conventionally, in order to control the size of the emulsified material, a method of controlling the amount of the surfactant added to the emulsified material was used. However, according to the present invention, the size of the emulsified material can be adjusted by adjusting the width of the orifice 58 only. However, the width of the orifice 58 has a minimum designed value, and thus there is a minimum limit of the size of the emulsified material.

In particular, in the case of cosmetics manufactured using an emulsification apparatus, the size and content of emulsified particles are important factors for determining the quality of cosmetics. In order for emulsified particles to form, the injection ratio of the extracorporeal fluid to the inner fluid should generally be the same or higher. For example, the injection volume of the extracorporeal fluid may be 1 to 30 times the injection volume of the inner fluid.

In the case of a microfluidic channel 100 using a single sound pressure as in the present invention, the flow rate of the fluid is determined by the structural elements of the fluid channel 100 and the flow conditions of the fluid, . Structural elements of the fluid channel 100 include, for example, the height of the channel, the width of the orifice, and the width ratio of the injection channels of the respective fluids. The flow conditions of the fluid are, for example, the intensity of the sound pressure, the flow ratio of the two fluids, and the viscosity ratio of the two fluids.

The emulsified particles have a higher viscosity as the channel height is lower, the width of the orifice is narrower, the sound pressure is higher, the flow rate of the fluid to the inner fluid is larger and the viscosity of the inner fluid is higher than that of the fluid And on the contrary, the size of the emulsified particles becomes large.

In the present invention, as a method of controlling the flow rate ratio between the inner fluid and the outer fluid, a method of controlling the inner diameter of each inlet of the inner fluid and the outer fluid is used. Specifically, when the inner diameter of the outer fluid injection port is made two times wider than the inner diameter of the inner fluid injection port, the flow rate of the outer fluid under the single sound pressure is increased by two times as compared with the inner fluid. In this way, the flow rate ratio between the inner fluid and the outer fluid can be adjusted.

Further, in order to increase the content of the emulsified particles, the flow ratio of the two fluids should be maximized to be the same. However, when the inner fluid moves faster than the outer fluid, the force to break the flow of the inner fluid through the outer fluid is insufficient, and the formation of the emulsion particle becomes difficult.

Accordingly, in the present invention, by adjusting the width ratio of the outer fluidized channel and the inner fluidized channel, even if the injection flow rate ratio of the two fluids is not adjusted, the content of the emulsified particles Can be adjusted. For example, if the width of the traumatic fluid channel is reduced to half the width of the upper fluid channel, the velocity of the traumatic fluid at the junction where the two fluids meet is twice as fast, Not only emulsion particles are formed with the same effect as when the inner fluid is injected at the same flow rate ratio, but also because the inner fluid is injected twice, the content can also be doubled.

The emulsified material passing through the joint portion 56 and the orifice 58 moves along the emulsified material moving tube 57. At this time, a first emulsification material passage 59 is formed at an end of the emulsification material movement pipe 57 to communicate with the second channel 80 to serve as a passage through which the emulsification material escapes from the first channel 50. The second channel 80 is formed with a second emulsified material passage 81 that communicates with the first emulsified material passage 59 and serves as a passage for receiving the emulsified material into the second channel 80.

The emulsified material flowing into the second channel 80 through the second emulsified material passage 81 moves to the additional leg portion 84 along the emulsified material pipe 81a. However, the second channel (80) is provided with a gradually moving tube (83), which is the path of the incremental agent transferred from the incremental injection pipe (46). The incremental agent stored in the gradual container 45 in the housing 10 is moved to the gradual injection port 82 of the second channel 80 along with the gradual injection pipe 46 by the negative pressure. Thus, the incremental agent introduced into the second channel 80 through the incremental injection port 82 is transferred to the additional leg 84 along the incremental movement tube 83.

That is, in the downstream of the gradual movement tube 83, there is provided an additional step of bringing the emulsified material transferred to the second channel 80 through the second emulsified material passage 81 into contact with the incremental agent moved along the incremental movement tube 83 Since the ridge portion 84 is formed, an incremental contact with the emulsified material is made in the additional ridge portion 84.

The emulsified material in contact with the thickening agent moves to the stirring channel (86) to cause mixing of the emulsifying agent and the emulsifying agent. Specifically, the emulsified material in contact with the thickener moves to the stirring channel 86, which is bent a plurality of times through the stirring inlet channel 85, and the agitated emulsion material, which has been stirred through the stirring channel 86, And flows along the stirring flow-out channel 87 and is discharged to the tube 60.

A centrifugal force may be generated in the flow of the fluid passing through the stirring channel 86 by providing the flow channel in the form of a bent (curved) shape, and at the same time, a vortex may be formed in the flow of the fluid have. And the generation of centrifugal force and vortex can activate the mixture of the agglomerating agent and the emulsifying agent.

Further, as the stirring channels 86 are bent in the staggered direction, the moving directions of the fluids can be switched in opposite directions, and the collision between the forwarded fluids can further activate the mixing of the thickening agent and the emulsified material.

In addition, since the stirring channel 86 has a curved shape, the installation area of the second channel 80 having a relatively long channel can be reduced while providing a sufficient mixing route.

However, the shape of the stirring channel 86 according to the present embodiment is not limited to a bent shape in a staggered direction, but may be a shape bent in the same direction or a combination of two shapes, and may have various shapes capable of forming other vortices have.

However, the stirring method according to the present embodiment is not limited to the vortex type, and the method of increasing the surface area by stacking the two fluids, applying the electric field, using the acoustic wave, and stirring in the other microfluidic channel And the like. Hereinafter, the process of mixing the emulsifying agent with the emulsifying agent by moving the emulsifying agent in contact with the thickening agent along the stirring channel 86 will be described.

FIG. 4 is an enlarged view of part A of FIG. 3, and is a plan view showing a detailed structure of a stirring channel.

The stirring channel 86 is provided with one or more agitating flow portions for providing rotational paths in different directions so that the agitating agent and the emulsifying agent are mixed with each other. In the present embodiment, four stirring flow portions are shown, but the number of stirring flow portions is not limited thereto.

The agitating flow portions may have a structure corresponding to each other. Therefore, in this specification, one stirring fluid flow portion 86a of the four stirring fluid flow portions is taken as an example.

The agitation fluidization section 86a includes a first rotation path 861 for guiding the magnifying agent and the emulsified material to rotate in one direction, a second rotation path 862 for guiding the magnifying agent and the emulsion material to rotate in different directions, . Between the first rotation path 861 and the second rotation path 862, a direction changing path 863 for changing the direction of rotation of the emulsifying agent and the emulsifying material is provided. That is, the first rotation path 861 guides the entering fluid to rotate in one direction, the second rotation path 862 guides the fluid rotated in one direction to be rotated in the other direction, and the direction switching path 863 Switches the direction of rotation of the fluid between the first rotation path 861 and the second rotation path 862. [

Accordingly, the emulsified material in contact with the thickening agent passing through the additional leg portion 84 is rotated in the counterclockwise direction through the first rotation path 861 to perform primary stirring. Then, the increased emulsified material having undergone the primary agitation passes through the direction changing path 863 and then rotates in the clockwise direction through the second rotation path 862 to perform secondary agitation. That is, the emulsifying material to which the thickening agent has been contacted rotates in different directions through the first rotation path 861 and the second rotation path 862, so that the agitation agent and the emulsifying material are actively stirred.

The increased emulsion material passing through the stirring channel 86 in this manner is transferred to the tube 60 through the emulsion material outlet 88 past the stirrer outlet channel 87. The tube 60 is made of a transparent material so that the user can identify the emulsified material moving from the outside through the tube 60. At this time, only the portion of the housing 10 surrounding the tube 60 should be made of a material that can be visually confirmed from the outside, so that the emulsified material moving through the tube 60 can be confirmed from the outside.

A pump 70 is installed at the end of the tube 60 and the user can take out the emulsified material that has passed through the cosmetic composition manufacturing apparatus 1 through the discharge port of the pump 70.

Hereinafter, the flow of the fluid will be described in detail.

First, the process of extracting O / W emulsified particles will be described as follows.

In order to extract the O / W emulsified particles, the extracellular fluid may be a hydrophilic fluid such as water and the inner fluid may be a hydrophobic fluid such as oil. Then, the hydrophilic fluid is stored in the outer container (21) and the hydrophobic fluid is stored in the inner container (22).

In this state, when the user presses the pump 70, the pressure of the fluid receiving space and the fluid moving path in the housing 10 becomes high. Then, when the user releases the pressure of the pump 70, a negative pressure is applied to the fluid receiving space and the fluid movement path, so that the hydrophilic fluid and the hydrophobic fluid are drawn out from the respective containers.

Specifically, the hydrophilic fluid is moved along the trauma fluid injection tube 30 to the trauma fluid injection port 51 of the first channel 50, and the hydrophobic fluid flows along the intracardiac fluid injection tube 40 to the first channel 50 To the inner fluid injection port 54 of the internal combustion engine. The hydrophilic fluid moved to the first channel 50 moves to the joint portion 56 along the first branch tube 52 and the second branch tube 53 and the hydrophobic fluid moves along the inner fluid moving tube 55 And moves to the joint portion 56. That is, the hydrophilic fluid and the hydrophobic fluid meet each other at the joint portion 56 of the first channel 50.

The inner fluid and the outer fluid flow through the orifice 58 to cause emulsification and the emulsified material passing through the orifice 58 moves along the emulsified material moving tube 57. That is, an emulsified material in which a hydrophilic fluid surrounds a hydrophobic fluid is formed. The emulsified material formed according to this process is called oil-in-water (O / W) emulsion because it is a structure in which oil is dispersed in water.

At this time, it is preferable that the emulsifying material moving pipe 57 is made of a hydrophilic material or coated on the inner wall of the pipe. Specifically, when the emulsifying material moving tube 57 is made of a hydrophilic material, the hydrophilic fluid portion is moved to the emulsifying material moving tube (not shown) 57). Therefore, the O / W emulsified particles as described above can be smoothly moved along the emulsified matter moving tube 57 while maintaining the shape and structure thereof. Here, the water contact angle (WCA) with water may be set to 0 to 50 degrees when the emulsifying material moving pipe 57 has hydrophilicity. In this case, the O / W emulsified particles can flow more smoothly.

The O / W emulsified particles having passed through the first emulsified material passage 59 of the first channel 50 are moved to the second channel 80 stacked on the first channel 50. Specifically, the O / W emulsified particles are dispersed in the second channel 80 along the second emulsified material passage 81 of the second channel 80 communicated with the first emulsified material passage 59 of the first channel 50, .

The O / W emulsified particles flowing into the second channel 80 through the second emulsified material passage 81 are moved to the additional leg portion 84 along the emulsified material pipe 81a. The incremental agent moved from the thickener vessel 45 to the incremental injection port 82 formed in the second channel 80 through the incremental charge pipe 46 is then passed through the incremental flow tube of the second channel 80 83 to the additional leg portion 84. Therefore, the O / W emulsified particles and the thickener come into contact with each other at the additional leg portion 84.

Then, the O / W emulsion particles contacted with the thickener move to the stirring channel 86 to stir the thickener and O / W emulsified particles, and the O / W emulsion particles having been stirred with the thickener And moves to the agitating material outlet 88.

The O / W emulsified particles, which have been agitated by the agitating material discharge port 88, can be taken out to the user through the injection port of the pump 70 through the tube 60.

Similarly, the process of extracting W / O emulsified particles will be described as follows.

In order to extract the W / O emulsified particles, the extracellular fluid may be a hydrophobic fluid such as oil and the intrinsic fluid may be a hydrophilic fluid such as water. Then, the hydrophobic fluid is stored in the outer container 21 and the hydrophilic fluid is stored in the inner container 22.

In this state, when the user presses and releases the pump 70, negative pressure is applied to the fluid receiving space and the fluid movement path, and the hydrophobic fluid and the hydrophilic fluid are drawn out of the respective containers.

Specifically, the hydrophobic fluid moves along the traumatic fluid injection tube 30 to the traumatic fluid injection port 51 of the first channel 50, and the hydrophilic fluid flows along the intimal fluid injection tube 40 to the first channel 50 To the inner fluid injection port 54 of the internal combustion engine. The hydrophobic fluid and the hydrophilic fluid moved to the first channel (50) meet each other at the joint portion (56) of the first channel (50). At this time, the inner fluid and the outer fluid flow through the orifice 58, and the emulsified material passing through the orifice 58 moves along the emulsion moving tube 57. That is, an emulsified material in which the hydrophobic fluid surrounds the hydrophilic fluid is formed.

The emulsified material formed by this process is called W / O (Water in Oil) emulsified particles because it is a structure in which water is dispersed in the oil.

At this time, it is preferable that the emulsifying material moving pipe 57 is made of a hydrophobic material or coated on the inner wall of the pipe. Specifically, when the emulsifying material moving tube 57 is made of a hydrophobic material, the hydrophobic fluid portion of the emulsifying material is moved to the emulsifying material moving tube 57). Therefore, the W / O emulsified particles as described above can be smoothly moved along the emulsion moving tube 57 while maintaining the shape and structure thereof. Here, when the emulsifying material moving pipe 57 has hydrophobicity, the contact angle WCA with water may be set to 70 to 120 degrees. In this case, the W / O emulsion particles can flow more smoothly.

The W / O emulsified particles having passed through the first emulsified material passage 59 of the first channel 50 are moved to the second channel 80 stacked on the first channel 50. Specifically, the W / O emulsified particles are dispersed in the second channel 80 along the second emulsified material channel 81 of the second channel 80, which communicates with the first emulsified material channel 59 of the first channel 50, .

The W / O emulsified particles flowing into the second channel 80 are moved to the additional leg portion 84 along the emulsion material pipe 81a. The incremental agent moved from the thickener vessel 45 to the incremental injection port 82 formed in the second channel 80 through the incremental charge pipe 46 is then passed through the incremental flow tube of the second channel 80 83 to the additional leg portion 84. Therefore, the W / O emulsified particles and the thickener come into contact with each other at the additional leg portion 84.

Then, the W / O emulsion particles in contact with the thickener migrate to the stirring channel 86 to agitate the thickener and the W / O emulsified particles, and the W / O emulsion particles that have been stirred with the thickener And moves to the agitating material outlet 88.

The agitated W / O emulsified particles moved along the agitating material outlet 88 can be taken out to the user through the injection port of the pump 70 through the tube 60.

As described above, according to the present invention, since the thickener is added to the emulsified material after the emulsified material is formed, the emulsified material can be increased without interfering with the formation of the emulsified particles before or at the same time as the formation of the emulsified particles, It is possible to increase the feeling of use and stability.

Further, according to the present invention, since the emulsified material (emulsion) is produced by the operation of the user's pump and the emulsified material is discharged to the outside, it is possible to manufacture and supply the emulsified material at a time required by the user There are advantages.

The foregoing description is merely illustrative of the technical idea of the present invention and various changes and modifications may be made by those skilled in the art without departing from the essential characteristics of the present invention.
