Description

Field of the Technology

[0001] The present invention relates to a Portable Electrospinning Device.

Background Art

[0002] Generally, an electrospinning device is known as a device that applies a high voltage between a nozzle part that spins a spinning solution and a substrate so that the spinning solution is spun in the form of nanofibers. Also, usually, nanofibers produced by an electrospinning device are used for ultra-high-precision filters, materials for the electric and electronic industries, medical biomaterials, and the like.

[0003] Conventional electrospinning devices have a problem that it is difficult to apply them to beauty devices because they are large and heavy in volume, require a separate installation space, and perform electrospinning in a fixed state.

[0004] Recently, research has been conducted to miniaturize conventional electrospinning devices for application in various fields. However, in the case of such a small electrospinning device, since the spinning nozzle for spinning the spinning solution has a shape protruding to the outside, there are problems such as the risk of electric shock and spark generation due to the protruding nozzle.

Modes for Carrying Out the Invention

[0029] Hereinafter, specific embodiments of the present invention will be described in detail with reference to the drawings.

[0030] In the description of the present invention, when it is determined that a specific description of related known configurations or functions may obscure the gist of the present invention, the detailed description thereof will be omitted.

[0031] Figure 1 is a schematic perspective view showing a portable electric radiation device according to one embodiment of the present invention, Figure 2 is a schematic cross-sectional view showing a cross-section of the portable electric radiation device 1 of Figure 1, Figure 3 is a schematic perspective view showing the guide structure of Figure 1, and Figure 4 is a view of the guide structure of Figure 1 from below.

[0032] Referring to Figures 1 to 4, a portable electric radiation device 1 according to one embodiment of the present invention may include a case 100 that forms the exterior, a storage section 200 that can store a radiation solution, a discharge section 300 that discharges the radiation solution to the outside, a power supply section 400 that supplies current to the discharge section 300, a voltage amplification section 500 that amplifies the voltage supplied from the power supply section 400 and applies the voltage to the discharge section 300, and a guide structure 600 that can separate the discharge section 300 from the outside by a specified distance. The portable electric radiation device 1 may also include a control section (not shown) that adjusts the amount of radiation solution discharged to the outside.

[0033] Furthermore, the radioactive solution may include cosmetics as a substance that can be applied to the user's skin. For example, the radioactive solution may contain a polymer, water, and a solvent, and the ratios of polymer, water, and solvent may be 1% to 30%: 5% to 89%: 10% to 94%. For example, if the radioactive solution contains 1% polymer and 5% water, the solvent may make up 94%.

[0034] Furthermore, if the radiant solution contains more than 20% solvent, it can rapidly solidify into a film on the user's skin within seconds. Specifically, the solvent in the radiant solution may be 50% to 90%. In this case, since the portable electric radiation device 1 has an opening 640 of a predetermined size, the risk of electric shock can be reduced even when a high proportion of solvent is electrically emitted.

[0035] However, the type of radioactive solution is not limited to this, and the radioactive solution may include medical drugs. In this case, the portable electrical radiation device 1 may also be used as a medical supply.

[0036] In this embodiment, the +y direction is defined as upward and the -y direction as downward, with reference to Figure 2, and the configuration of the portable electrical radiation device 1 will be described in detail below.

[0037] The case 100 may be provided in a size that is portable to the user. For example, the length (L1) of the case 100 may be 10 cm to 20 cm, and the height (h) and width (w) may be 1 cm to 3 cm, respectively.

[0038] Case 100 can be formed in a three-dimensional shape that can be grasped by the user. For example, Case 100 can be provided in shapes such as cylindrical or rectangular prism. Also, the cross-sectional area (xz plane) of Case 100 may decrease from the top to the bottom. However, the shape of Case 100 is not limited as long as it can be grasped by the user.

[0039] The case 100 may consist of a lower case portion 102 through which the discharge portion 300 (described later) passes, a side case portion 104 with space for inserting a storage portion 200, and an upper case portion 106 that can be selectively opened for replacement of the storage portion 200. The upper case portion 106 may also be provided in the shape of a lid that can be selectively opened for replacement of the storage portion 200.

[0040] A user-operable switch 110 may be provided on the outside of the case 100. The user can use the switch 110 to turn the portable electric radiation device 1 on or off.

[0041] Alternatively, the switch 110 can be made of a conductor (metal), and the voltage amplification unit 500 (described later) and the switch 110 can be connected by a first connecting wire 510. In this case, since the switch 110 forms a grounded area, a voltage of opposite polarity to that of the discharge unit 300 can be applied to the user's skin. Specifically, by the user grasping the switch 110, a positive or negative electrode is formed on the skin, and the skin acts as a collector, allowing the radiant solution to be discharged onto the skin from the discharge unit 300 (described later). Here, the first connecting wire 510 can be understood as a conductor connecting the voltage amplification unit 500 and the switch 110.

[0042] Furthermore, a display unit 120 may be provided on one side of the case 100. The display unit 120 may show the type of radioactive solution, the remaining amount of radioactive solution, and the estimated replacement time for the storage unit 200.

[0043] Furthermore, the amount of radiant solution discharged from the discharge unit 300 can be adjusted using the display unit 120 or the switch 110.

[0044] The storage unit 200 is located inside the case 100 and can store a radioactive solution. The radioactive solution is stored inside the storage unit 200, and the storage unit 200 may be provided in the form of a replaceable cartridge.

[0045] Furthermore, a quantitative dispensing unit 210 capable of dispensing a fixed amount of the radioactive solution stored in the storage unit 200 may be provided above or on the side of the storage unit. For example, the quantitative dispensing unit 210 may be piston-shaped and capable of pushing a fixed amount of the radioactive solution stored in the storage unit 200 into the dispensing unit 300. The amount of radioactive solution pushed out of the dispensing unit 300 by the quantitative dispensing unit 210 can be understood as the amount discharged into the dispensing unit 300. In this way, the radioactive solution discharged into the dispensing unit 300 can be ejected to the outside by electrical radiation, as described later.

[0046] The discharge unit 300 can be electrically connected to the voltage amplification unit 500 so that the radioactive solution stored in the storage unit 200 can be discharged to the outside. The discharge unit 300 can also be electrically connected to the voltage amplification unit 500, which will be described later, by a second connecting wire 520.

[0047] The dispensing section 300 is provided by a needle, and the diameter of the needle may be in the nanometer range.

[0048] Furthermore, the discharge section 300 may be made of a metallic material to which an electric current can be applied.

[0049] The discharge portion 300 may protrude from the outside of the case 100 by a certain length (d2), and in this case, the guide structure 600, which will be described later, can prevent the discharge portion 300 protruding from the outside of the case 100 from directly contacting the skin.

[0050] The power supply unit 400 may be located inside or outside the case 100 and may supply current to the discharge unit 300 via the voltage amplification unit 500. Specifically, the power supply unit 400 may include one or more batteries.

[0051] The voltage amplification unit 500 can amplify the voltage supplied from the power supply unit 400 and apply the voltage to the discharge unit 300. This voltage amplification unit 500 can apply a high voltage to the discharge unit 300. The voltage amplification unit 500 and the discharge unit 300 can be electrically connected by a second connecting wire 520.

[0052] The guide structure 600 is provided in a cylindrical shape extending downward from one end of the case 100 and may surround at least a portion of the discharge section 300.

[0053] Such a guide structure 600 can prevent the discharge nozzle 300 from coming into direct contact with the skin. In this case, the user can apply the radiant solution to their skin from the discharge nozzle 300 to which voltage is applied, without the risk of electric shock.

[0054] Furthermore, the user can easily apply the radiant solution to their skin by grasping the portable electric radiation device 1 and bringing the guide structure 600 into contact with their skin.

[0055] In this embodiment, the guide structure 600 will be described as having a cylindrical shape with length (L2), outer radius (R), inner radius (r), and thickness (t). Here, the length (L2) of the guide structure 600 may be 5 mm to 80 mm, the outer radius (R) may be 5 mm to 20 mm, and the thickness (t) may be 1 mm to 5 mm. Note that the shape of the guide structure 600 is not limited to a cylindrical shape, but can be various shapes such as a square tube or a triangular tube.

[0056] One end of the guide structure 600 may be connected to the case 100, while the other end may be left open as a free end.

[0057] Specifically, the guide structure 600 may include a connecting portion 620 that is connected to the case 100, a side portion 630 that extends downward from the connecting portion 620 and surrounds the discharge portion 300, and a lower portion 610 that extends from the side portion 630 and has an opening through which the discharge solution can pass.

[0058] The connecting portion 620 of the guide structure 600 may be formed integrally with the lower case 102. Alternatively, the connecting portion 620 may be formed to be selectively separable from the lower case 102. If the connecting portion 620 is selectively separable from the lower case 102, the user can replace the guide structure 600. In this case, the guide structure 600 may also be manufactured as a separate component and used in combination with a known portable electric radiation device.

[0059] The side portion 630 of the guide structure 600 may surround at least a part of the discharge portion 300.

[0060] Furthermore, multiple openings 640 may be formed in the side portion 630, and the spacing between the multiple openings 640 may be kept constant.

[0061] Furthermore, the opening 640 may be slit-shaped, formed in the direction in which the discharge section 300 extends.

[0062] Furthermore, the surface area of ​​the opening 640 formed in the side portion 630 may be 60% to 90% of the surface area of ​​the guide structure 600. Note that the surface area can be understood as the area when the guide structure 600 is unfolded in an unfolded view.

[0063] In this way, by increasing the surface area occupied by the opening 640 in the guide structure 600, the evaporated solvent of the radiant solution can escape from the inside of the guide structure 600 to the outside, thereby reducing the risk of electric shock to the user.

[0064] The lower surface portion 610 of the guide structure 600 may be open to allow the radiant solution to pass through and be applied to the skin. For example, the cross-section of the lower surface portion 610 may be ring-shaped.

[0065] Furthermore, a metal collector is provided on the lower surface portion 610, which can collect the radiation solution discharged from the discharge portion 300. A detailed explanation of the metal collector will be given later.

[0066] The guide structure 600 may be made of an insulated material. For example, the guide structure 600 may be made of plastic, rubber, or elastomer.

[0067] In this way, by providing the guide structure 600 with an insulator, it is possible to prevent the radiant solution from adhering to the guide structure 600.

[0068] Furthermore, by making the guide structure 600 from an elastic material such as an elastomer, it is possible to prevent the user's skin from being damaged by the guide structure 600.

[0069] The guide structure 600 may be formed to extend downward from the discharge section 300. In this case, the guide structure 600 can move the discharge section 300 away from the skin by a predetermined distance.

[0070] The distance (d1) between the lower end of the discharge section 300 and the lower end of the guide structure 600 may be 5 mm to 60 mm. Preferably, the distance (d1) between the lower end of the discharge section 300 and the lower end of the guide structure 600 may be 20 mm to 50 mm. Note that the distance (d1) between the lower end of the discharge section 300 and the lower end of the guide structure 600 is a distance measured parallel to the y-axis (vertical direction) and can be understood as the distance between the discharge section 300 and the user's skin when the portable electric radiation device 1 is in contact with the user's skin.

[0071] The critical significance of the distance (d1) between the lower end of the discharge section 300 and the lower end of the guide structure 600 will be explained below.

[0072] If the distance (d1) between the lower end of the discharge section 300 and the lower end of the guide structure 600 is 20 mm or less, there is a risk of electric shock due to sparks occurring when the radiant solution is applied to the skin.

[0073] Furthermore, if the distance (d1) between the lower end of the discharge section 300 and the lower end of the guide structure 600 is 50 mm or more, the radiant solution may not be discharged, or even if it is discharged, the radiant solution may not be properly applied to the skin.

[0074] Furthermore, when viewed from below the guide structure 600, the discharge section 300 is positioned at the center of the guide structure 600, and the guide structure 600 may have a shape that surrounds the discharge section 300. The distance between the discharge section 300 and the guide structure 600 (outer radius (R) and inner radius (r)) may be set differently depending on the type of discharge solution and the application area.

[0075] Thus, by providing the guide structure 600 on the portable electric radiation device 1, the user can apply the radiation solution to their skin by directly contacting the guide structure 600 with their skin without having to worry about adjusting the distance between the discharge part 300 and their skin. Furthermore, the provision of the guide structure 600 allows the user to apply the radiation solution to their skin without the risk of electric shock.

[0076] Figure 5 shows a portable electric radiation device 1' according to another embodiment of the present invention. In the following, the portable electrical radiation device 1' will be described with reference to Figure 5.

[0077] The guide structure 600' in Figure 5 may have the same size and shape as the guide structure 600 detailed in Figures 1 to 4. However, compared to the embodiments in Figures 1 to 4, there is a difference in that a metal collector 700 is provided at the bottom of the guide structure 600'. Therefore, the explanation will focus on the differences, and for identical parts, the previous explanation and drawing reference numerals will be used.

[0078] The metal collector 700 may be provided as a conductor at the lower end of the guide structure 600' (the lower surface portion 610 of the guide structure 600 as detailed in Figures 1 to 4). That is, the metal collector 700 may be spaced at a predetermined distance from the discharge portion 300, and this distance (in the direction parallel to the y-axis) may be 5 mm to 50 mm, preferably 20 mm to 50 mm.

[0079] The metal collector 700 may be provided around the lower end of the guide structure 600'. If the guide structure 600' is formed in a cylindrical shape, the metal collector 700 may be provided in a ring shape.

[0080] The metal collector 700 can receive a voltage from the voltage amplifier 500' via the first connecting wire 510'. The first connecting wire 510' can be understood as a conductor connecting the voltage amplifier 500' and the metal collector 700.

[0081] When a positive or negative voltage is applied to the discharge section 300', the metal collector 700 is subjected to the opposite polarity (negative or positive) of the discharge section 300'. In this case, the radiant solution discharged from the discharge section 300' is radiated towards the metal collector 700, and the radiant solution can be applied to the skin.

[0082] Figure 6 shows a cross-section of a guide structure 600'' according to another embodiment of the present invention.

[0083] In the following description, another embodiment of the present invention, the guide structure 600'', will be explained with reference to Figure 6. However, there are differences between this embodiment and the previously described embodiment in terms of the cross-sectional shape of the guide structure 600'' and the presence of a metal collector cover 710. Therefore, the differences will be explained in detail, and the same parts will be described in the previous description and refer to the same reference numerals.

[0084] Referring to Figure 6, a metal collector cover 710 may be provided at the lower end of the metal collector 700''. The metal collector cover 710 may be made of an insulator. In this case, the radiant solution emitted from the discharge section 300'' can be focused by the metal collector 700'', and the insulator metal collector cover 710 can prevent the current from being directly applied to the skin.

[0085] Furthermore, the inner radius (r) of the guide structure 600'' may increase from the top to the bottom. In this case, the outer radius (R) of the guide structure 600'' can be kept constant, so the thickness (t) of the guide structure 600'' may decrease from the top to the bottom. The radiant solution can be easily guided toward the skin by a guide structure 600'' of this shape.

[0086] Figure 7 is a schematic diagram showing a user holding the portable electric radiation device 1 shown in Figure 1.

[0087] The operation process of the portable electric radiation device of the present invention will be explained below with reference to Figures 1 to 7. For the example, the radiation solution will be described as sunscreen cream.

[0088] The user can activate the portable electric radiation device 1 by operating the switch 110 on the portable electric radiation device 1.

[0089] Subsequently, the user may bring the portable electric radiation device 1 into contact with the user's skin (e.g., face) where they intend to apply sunscreen cream. When the end of the discharge unit 300 and the skin are at a predetermined distance (d), sunscreen cream may be emitted from the discharge unit 300.

[0090] Specifically, the sunscreen cream moves from the storage unit 200 to the dispensing unit 300, and the sunscreen cream is dispensed from the lower end of the dispensing unit 300. Subsequently, the power supply from the power supply unit 400 is amplified by the voltage amplification unit 500 and applied to the dispensing unit 300.

[0091] In the embodiment shown in Figures 1 to 4 (where the voltage amplifier 500 and the switch 110 are connected), the switch 110 is grounded to the user's body, and the user's body functions as the collector, so a voltage opposite to that of the discharge unit 300 can be applied to the user's body.

[0092] On the other hand, in the embodiment shown in Figure 5 (where the voltage amplification unit 500' and the metal collector 700 are connected), a voltage opposite to that applied to the discharge unit 300' may be applied to the metal collector 700.

[0093] In this way, by applying voltages of opposite polarity to the dispensing unit 300 and the user's body, or by applying voltages of opposite polarity to the dispensing unit 300' and the metal collector 700, sunscreen cream can be electrically discharged from the dispensing unit 300 and applied to the skin.

[0094] In this case, the guide structure 600 can prevent the discharge section 300 from making direct contact, and the evaporated solvent can escape to the outside through the opening 640 formed in the guide structure 600, thereby reducing the risk of electric shock in a confined environment.

[0095] The effects of the aforementioned portable electric radiation devices will be explained below.

[0096] By providing a guide structure 600 to the portable electrical radiation device 1, the user can apply the radiation solution to their skin by directly contacting the guide structure 600 with their skin without having to worry about adjusting the distance between the discharge part 300 and their skin.

[0097] Furthermore, the provision of the guide structure 600 allows the user to apply the radiant solution to their skin without the risk of electric shock.

[0098] Furthermore, the portable electric radiation device may include a guide structure 600 to prevent the discharge section 300 from coming into direct contact with the skin.

[0099] Furthermore, by forming an opening 640 in the guide structure 600, the evaporated solvent can escape from the inside to the outside of the guide structure 600, thereby reducing the risk of electric shock to the user.

[0100] Furthermore, by providing the guide structure 600 with an insulator, it is possible to prevent the radiant solution from adhering to the guide structure 600.

[0101] Furthermore, by making the guide structure 600 from an elastic material such as an elastomer, it is possible to prevent the user's skin from being injured by the guide structure 600.

[0102] Furthermore, portable electrical radiation devices can be offered in a small size, making them easily portable for users.
