Therefore, the features defined as "first" or "second" may explicitly or implicitly include at least one of such features. In addition, the technical solutions between the various embodiments can be combined with each other, but this must be based on the fact that they can be implemented by ordinary technicians in this field. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by this utility model.

[0051] The utility model proposes a skin care device, referring to Figures 1-4 , the skin care device 10 comprises:

[0052] The housing assembly 100 is formed with an inner cavity 110, a first air inlet 120 and a first air outlet 130, wherein the first air inlet 120 and the first air outlet 130 are respectively communicated with the inner cavity 110;

[0053] The care component 200 is at least partially housed in the inner cavity 110 and is used for skin care;

[0054] The heat dissipation assembly 300 is disposed in the inner cavity 110 and is used to drive air into the inner cavity 110 through the first air inlet 120 and to be discharged out of the inner cavity 110 through the first air outlet 130;

[0055] The housing assembly 100 includes a first end portion 150, a second end portion 160, and a peripheral side portion 140 connected between the first end portion 150 and the second end portion 160. The peripheral side portion 140 includes a first side portion 141, a second side portion 142, and a third side portion 143. The first side portion 141 and the second side portion 142 are spaced apart and arranged opposite to each other, and the third side portion 143 is arranged between the first side portion 141 and the second side portion 142.

[0056] One of the first air inlet 120 and the first air outlet 130 is formed on the first side portion 141 , and the other is formed on the second side portion 142 ;

[0057] The heat dissipation assembly 300 includes a fan 310 . The fan 310 is located between the first side portion 141 and the second side portion 142 . The fan 310 has a second air inlet 311 . The second air inlet 311 is disposed toward the third side portion 143 .

[0058] Skin care device 10 refers to a device that can improve and regulate human skin based on human physiological functions. Based on their cosmetic benefits, skin care devices 10 include, but are not limited to, hair removal devices, whitening devices, skin rejuvenation devices, wrinkle removal devices, and freckle removal devices. In some embodiments, a single skin care device 10 can have one or more cosmetic benefits. For example, a single skin care device 10 can simultaneously remove hair and achieve skin rejuvenation, or alternatively, remove hair, whiten skin, and achieve skin rejuvenation.

[0059] like Figure 2 As shown, in this embodiment, the housing assembly 100 of the skin care device 10 is primarily used for user gripping and provides a mounting location for other components. To facilitate gripping, the housing assembly 100 can be designed into an ergonomic shape, such as a streamlined shape or a handle with a non-slip design, to improve grip comfort and stability.

[0060] The material of the housing assembly 100 can be selected based on different needs. For example, to reduce the overall weight, a lightweight, high-strength material such as carbon fiber or aluminum alloy can be used. Considering the user's comfort when holding, the surface of the housing assembly 100 can be made of a soft-touch material such as silicone or polyurethane coating. These materials not only provide a soft touch, but also can increase the anti-slip effect through surface treatment processes (such as spraying, plating, or rubber coating), thereby improving the user experience of the device.

[0061] like Figure 2 and Figure 3 As shown, the care component 200 is used to care for the skin. Different types of care components 200 are placed on the housing component 100 in different ways. For example, if the care component 200 cares for the skin by emitting light to irradiate the skin, the care component 200 can be placed completely within the inner cavity 110 of the housing component 100. If the care component 200 stimulates the skin by contacting the skin with electrodes and releasing current, a portion of the care component 200 is placed outside the housing component 100 for close contact with the skin. The electrodes can be made of materials that are highly conductive and safe for the skin, such as stainless steel, silver, or gold-plated copper. These materials not only effectively conduct current but also have good corrosion resistance, ensuring the stability of the device during long-term use.

[0062] Reference Figures 1-4 The housing assembly 100 includes a peripheral side portion 140 for accommodating most components, wherein the peripheral side portion 140 includes a first side portion 141 and a second side portion 142 disposed opposite each other, and a third side portion 143 connecting the first and second side portions 141 and 142. Preferably, since the housing assembly 100 forms an inner cavity 110, the third side portion 143 connects the ends of the first and second side portions 141 and 142, thereby increasing the volume of the inner cavity 110. The first air inlet 120 and the first air outlet 130 are respectively disposed on the first and second side portions 141 and 142, so that after air enters through the first air inlet 120, it flows through the heat dissipation component 300 and the care component 200, ensuring that all areas within the skin care device 10 are covered by air, and then discharged from the second air inlet 311, making the air flow smoother and helping to improve heat dissipation efficiency.

[0063] The heat dissipation assembly 300 includes a fan 310, which is typically made of a heat-resistant material, such as plastic or metal. The fan 310 is positioned between the first side portion 141 and the second side portion 142 within the inner cavity 110, with the second air inlet 311 of the fan 310 facing the third side portion 143. When the skin care device 10 is activated, the fan 310 first drives air into the inner cavity 110 from the first air inlet 120, then flows along the first side portion 141 toward the third side portion 143 before entering the second air inlet 311 of the fan 310. This allows the air to flow through a wider area. By placing the components required by the skin care device 10 along the air's path, the air can remove the heat generated by these components, ensuring that the skin care device 10 maintains a suitable temperature during use. Finally, the air is discharged from the skin care device 10 through the first air outlet 130. It is understandable that the first air inlet 120 may also be provided on the second side portion 142 , and the first air outlet 130 may also be provided on the first side portion 141 , and the present invention does not impose any limitation on this.

[0064] The skin care device 10 of the present invention disposes the first air inlet 120 and the first air outlet 130 on the first side 141 and the second side 142 of the skin care device 10, respectively, which are spaced apart from each other. The fan 310 is positioned between the first side 141 and the second side 142. This ensures that the distance between the fan 310 and the first air inlet 120 and the first air outlet 130 is not too far, facilitating the arrangement of the air duct within a limited space and reducing the volume occupied by the air duct. Furthermore, the second air inlet 311 of the fan 310 is positioned toward the third side 143, so that the second air inlet 311 is not directly facing the first air inlet 120 and the first air outlet 130. This makes the placement of the fan 310 more flexible and allows air to flow through more areas of the inner cavity 110 within the limited space. This allows a single fan 310 to dissipate heat for more components, thereby effectively balancing the volume and overall heat dissipation of the skin care device 10.

[0065] like Figure 1 、 Figure 2 and Figure 4 As shown, in some embodiments, the axial direction of the fan 310 is perpendicular to the direction from the first side portion 141 to the second side portion 142 .

[0066] The fan 310, positioned perpendicularly from the first side 141 toward the second side 142, draws air from a position closer to the third side 143. This reduces the distance between the second air inlet 311 of the fan 310 and the third side 143, thereby lengthening the distance between the first air inlet 120 and the second air inlet 311 and extending the air flow path. This allows air to flow from the first air inlet 120 to between the third side 143 and the second air inlet 311 of the fan 310, passing through a wider area. This helps ensure a more uniform cooling effect for all components within the inner cavity 110, prevents local overheating, and improves the stability and service life of the skin care device 10. Furthermore, the air flow path is closely aligned with the first side 141 and the third side 143, reducing flow resistance and thus improving heat dissipation efficiency.

[0067] By setting the fan 310 axially perpendicular to the width direction of the device, the fan 310 can be placed more neatly, which is convenient for the arrangement of other components, thereby making better use of the internal space of the skin care device 10, reducing the thickness of the skin care device 10, making the skin care device 10 more compact and portable, and improving the user experience.

[0068] like Figure 1 and Figure 4 As shown, in some embodiments, the first air inlet 120 is formed on the first side portion 141, and the orthographic projection of the fan 310 on the first side portion 141 overlaps with at least a portion of the first air inlet 120; and / or,

[0069] The first air outlet 130 is formed on the second side portion 142 , and the orthographic projection of the fan 310 on the second side portion 142 overlaps with at least a portion of the first air outlet 130 .

[0070] In the inner cavity 110 of the shell assembly 100, the flow of air is formed by the push of the fan 310. The air flow path is usually from the first air inlet 120, passes through the internal components, and is discharged from the first air outlet 130. Therefore, the smoothness of the air flow directly affects the heat dissipation effect of the skin care device 10.

[0071] In this embodiment, the orthographic projection of at least part of the fan 310 is arranged to overlap with the first air inlet 120 or the first air outlet 130, so that there is no excessive misalignment between the fan 310 and the first air inlet 120 or the first air outlet 130, and the direction in which the fan 310 inhales or exhausts air is consistent or nearly consistent with the direction of the first air inlet 120 or the first air outlet 130, ensuring that the air flows through more areas while avoiding the situation where the distance between the first air inlet 120 and the second air inlet 311 of the fan is too far, thereby reducing the occurrence of airflow dispersion, avoiding detours and collisions in the air flow, and preventing the air from forming vortices or countercurrents between the fan 310 and the first air inlet 120 or the first air outlet 130, so that the fan 310 can work more efficiently.

[0072] Preferably, in this embodiment, the positive projection of the axis of the fan 310 on the first side portion 141 can be located in the middle of the first air inlet 120, so that the distance between the second air inlet 311 of the fan 310 and the first air inlet 120 is closer. After the air enters the first air inlet 120, it moves vertically downward or vertically upward along the first side portion 141 to reach the second air inlet 311, making it easier for the fan 310 to pull air, and the components arranged between the first side portion 141 and the fan 310 can also obtain better heat dissipation effect.

[0073] like Figure 2 and Figure 5 As shown, in some embodiments, the care component 200 includes a cooling sheet 210 and a light-transmitting skin-adhesive member 220. The light-transmitting skin-adhesive member 220 is disposed at the first end 150 and is configured to contact the skin during use. The cooling sheet 210 is disposed within the housing component 100 and is thermally connected to the light-transmitting skin-adhesive member 220.

[0074] The heat dissipation assembly 300 further includes a radiator 320 and a heat dissipation pipe 330 . The radiator 320 is disposed between the second air inlet 311 and the third side portion 143 .

[0075] One end of the heat dissipation pipe 330 is connected to the cooling fin 210 , and the other end is connected to the radiator 320 .

[0076] The light-transmitting skin-adhesive member 220 is typically made of a crystal material, specifically sapphire, K9 glass, crystal glass, or other materials that meet the requirements of light-transmitting crystals. It can optionally be made of sapphire, and the shape and size of the light-transmitting skin-adhesive member 220 can be set according to actual needs. The light-transmitting skin-adhesive member 220 can be mounted on the first end 150 of the skin care device 10 by mechanical fixation or bonding, wherein the mechanical fixation method includes the use of a buckle, screw, or embedded design to ensure that the light-transmitting skin-adhesive member 220 is firmly mounted on the first end 150. During use, the light-emitting component 230 in the skin care device 10 is controlled to emit light toward the light-transmitting skin-adhesive member 220, so that the light is emitted from the light-transmitting skin-adhesive member 220 and irradiates the user's skin, thereby achieving skin care.

[0077] The cooling fins 210 and the heat dissipation assembly 300 are generally made of materials with high heat dissipation efficiency, such as metal alloys. The cooling fins 210 are connected to the radiator 320 via the heat pipe 330, so that the heat absorbed by the cooling fins 210 from the light-transmitting skin-applying member 220 can be quickly transferred to the radiator 320 via the heat pipe 330, and the heat of the radiator 320 disposed between the second air inlet 311 and the third side portion 143 of the fan 310 can be discharged from the inner cavity 110 through the air flow, so that the cooling fins 210 can continuously and effectively cool the light-transmitting skin-applying member 220. The cooling fins 210 can be directly disposed on the light-transmitting skin-applying member 220 to absorb the heat of the light-transmitting skin-applying member 220, or can be indirectly absorbed by other heat-conducting structures to absorb the heat of the light-transmitting skin-applying member 220, and the present invention does not impose any restrictions on this.

[0078] In this embodiment, the light-transmitting skin-adhesive component 220 is in direct contact with the skin when in use. After the heat on the skin is conducted to the light-transmitting skin-adhesive component 220, it is conducted to the radiator 320 through the cooling plate 210 and the heat dissipation pipe 330, and is finally carried out of the inner cavity 110 by the flowing air, thereby maximizing the use of the heat conduction capacity of the air flow and the heat dissipation pipe 330, improving the overall heat dissipation efficiency of the device, enabling the device to operate stably for a longer period of time, and enabling the light-transmitting skin-adhesive component 220 to be maintained in a lower and stable temperature range, thereby reducing the burning sensation caused by light exposure to the skin, greatly improving the user experience.

[0079] like Figure 2 and Figure 4 As shown, in some embodiments, the heat dissipation assembly 300 further includes an air guide 340 , which is disposed in the inner cavity 110 and forms a heat dissipation air duct in the housing assembly 100 ;

[0080] The fan 310 has a second air outlet 312 , and the heat dissipation duct extends from the second air outlet 312 to the first air outlet 130 ;

[0081] The care component 200 is at least partially located in the heat dissipation duct.

[0082] The air guide 340 can be designed as a closed pipe structure, with one end of the pipe structure connected to the second air outlet 312 of the fan 310, and the other end connected to the first air outlet 130, so as to guide the air blown out by the fan 310 to flow continuously to the inner cavity 110. The shape of the pipe structure can be set according to actual needs, and can be cylindrical, box-shaped or other irregular shapes; the air guide 340 can also be an open plate-like structure, guiding the airflow through specific angles and bending designs, and this embodiment does not impose any restrictions on this.

[0083] The setting of the air guide 340 allows the air to move along a clear and controlled flow path (i.e., the heat dissipation duct) in the inner cavity 110, and at least a portion of the care component 200 is set in the heat dissipation duct, so that air continuously flows through the care component 200, taking away the heat of the care component 200 and discharging it outside the device through the first air outlet 130, ensuring that the care component 200 can continue to maintain a low temperature during operation, avoiding excessive temperature affecting the performance of the skin care device 10.

[0084] In this embodiment, the air flow in the inner cavity 110 is regulated by the air guide 340, so that the internal space can be used more reasonably, the turbulence and eddy current of the air in the inner cavity 110 are reduced, the wind force of the fan 310 can be used more efficiently, and the workload of the fan 310 can be reduced, thereby extending the service life of the fan 310; and by controlling the path of air flow, local overheating problems caused by air stagnation or poor flow are avoided, and the cooling effect inside the skin care device 10 is significantly improved.

[0085] like Figure 2-Figure 4 As shown, in some embodiments, the care component 200 is used to output at least one of microcurrent, radiofrequency current, light, heat, and ultrasound from the first end 150 ;

[0086] The air guide 340 is provided between the fan 310 and the first end portion 150;

[0087] The second air outlet 312 is disposed toward the first end portion 150 .

[0088] Exemplarily, the care component 200 may include electrodes in a beauty instrument for outputting microcurrent or radiofrequency current to stimulate the skin, or may include a light-emitting structure in a hair removal instrument to emit light outward to irradiate and burn hair follicles. The present invention does not impose any restrictions on this.

[0089] In this embodiment, the first end 150 serves as the working end, meaning the care component 200 is typically located at the first end 150. Therefore, the air guide 340 is positioned between the fan 310 and the first end 150 to ensure that the fan 310 can effectively direct air to the care component 200 region. This ensures that when the care component 200 outputs various forms of energy, local overheating does not affect performance or cause user discomfort. The second air outlet 312 of the fan 310 is positioned toward the first end 150, facilitating the fan 310 to directly direct air to the care component 200, reducing kinetic energy loss during air movement and enabling continuous and smooth air flow. This in turn enhances the heat dissipation effect at the first end 150, ensuring that the care component 200 maintains a stable operating temperature when outputting energy.

[0090] like Figure 2 As shown, in some embodiments, the care component 200 includes a light-emitting component 230 and a translucent skin-adhering component 220. The light-emitting component 230 is arranged in the heat dissipation duct, and the light-emitting component 230 is used to emit light for skin care; the translucent skin-adhering component 220 is arranged at the first end 150, and the translucent skin-adhering component 220 is used for allowing the light emitted by the light-emitting component 230 to pass through for skin care.

[0091] The light-emitting component 230 is disposed within the housing and radiates light toward the light-transmitting element, thereby providing skin care through the light-transmitting element. The light-emitting component 230 can utilize a variety of light sources, such as LEDs, halogen lamps, or xenon lamps. These light sources can achieve different cosmetic effects depending on their wavelength and intensity.

[0092] Specifically, LED lights have the advantages of long life and low energy consumption, and are often used for general beauty treatments such as whitening, freckle removal, and wrinkle reduction. Different wavelengths of LED light can target different skin concerns. For example, blue light can be used to kill bacteria and reduce inflammation, while red light can help promote collagen production.

[0093] Halogen lamps, on the other hand, have a high luminous intensity and are suitable for deep skin treatments such as wrinkle removal and skin tightening. The broad spectrum of light they emit can effectively penetrate the surface of the skin and stimulate deeper tissues.

[0094] Xenon lamps, with their high brightness and strong penetrating power, are commonly used in beauty treatments such as photorejuvenation. They produce intense pulsed light, which has a significant effect on skin problems such as pigmentation and capillary dilation.

[0095] In addition, different wavelengths of light have different cosmetic effects. For example, blue light with a wavelength of 400-500nm is suitable for eliminating skin inflammation; red light with a wavelength of 600-700nm helps promote blood circulation and cell regeneration, enhancing skin elasticity; and near-infrared light (800-1000nm) can penetrate deep into the subcutaneous tissue, helping to reduce inflammation and accelerate skin repair.

[0096] During use, the light-emitting component 230 emits light toward the light-transmitting skin-adhering component 220, and then the light passes through the light-transmitting skin-adhering component 220 and illuminates the skin, thereby providing skin care. It is understandable that in order to prevent the light emitted by the light-emitting component 230 in the direction of the light-transmitting skin-adhering component 220 from being blocked, the component in this direction should be provided with appropriate holes or made of transparent materials. In this embodiment, the light-emitting component 230 is arranged in the heat dissipation duct, so that the heat generated by the light-emitting component 230 when emitting light can be quickly carried away by the cooling airflow, ensuring that the light intensity and stability of the light will not be affected by overheating during operation, while extending the service life of the light-emitting component 230.

[0097] like Figures 1-4 and Figure 6 As shown, in some embodiments, the first air inlet 120 is formed on the first side portion 141 , and the first air outlet 130 is formed on the second side portion 142 ;

[0098] The air guide member 340 includes a first air guide portion 341 forming a first air guide channel, a second air guide portion 342 forming a second air guide channel, and a third air guide portion 343 forming a third air guide channel. The second air guide portion 342 extends along the first side portion 141 toward the second side portion 142. The first air guide portion 341 extends from one end of the first air guide portion 341 and communicates with the second air outlet 312. The third air guide portion 343 extends from the other end of the first air guide portion 341 and communicates with the first air outlet 130.

[0099] The first air guide channel, the second air guide channel and the third air guide channel are connected in sequence to form a heat dissipation air channel;

[0100] The light emitting component 230 is disposed in the second air guiding channel.

[0101] In this embodiment, the first air guide channel, the second air guide channel and the third air guide channel are connected in sequence to form a heat dissipation air duct. During specific use, the fan 310 blows air from the second air outlet 312 into the first air guide channel, and allows the air to enter the second air guide channel along the first air guide channel. Since the light-emitting component 230 is located in the second air guide channel, the air flows through the light-emitting component 230 and takes away the heat generated by its operation, and finally flows out along the third air guide channel, completing the heat dissipation of the light-emitting component 230.

[0102] Among them, for example, the second air guide portion 342 can be connected to the side wall of the inner cavity 110 by snapping, bonding or welding, and covered on the light-emitting component 230, the first air guide portion 341 is a pipe connected to the second air guide portion 342, and can be set on the second air guide portion 342 by an integral molding manner, and one end of the first air guide portion 341 can be directly connected to the second air outlet 312 of the fan 310 by snapping, and the third air guide portion 343 is similar to the first air guide portion 341, and is used to guide the air in the second air guide portion 342 to the first air outlet 130, so that the movement of air is more standardized, reducing the occurrence of vortexes or backflows, and improving the heat dissipation efficiency of the skin care device 10.

[0103] like Figure 1 、 Figure 3 、 Figure 4 and Figure 7 As shown, in some embodiments, the housing assembly 100 includes a first wind shield 170 and a second wind shield 180. The first side portion 141 is provided with a first opening 141a. The first wind shield 170 passes through the first opening 141a and connects to the first side portion 141. An annular first air inlet 120 is formed between the periphery of the first wind shield 170 and the edge of the first opening 141a.

[0104] The second side portion 142 defines a second opening. The second wind shield 180 passes through the second opening and connects to the second side portion 142 . An annular first air outlet 130 is formed between the periphery of the second wind shield 180 and the edge of the second opening.

[0105] Taking the first windshield 170 as an example, the size and shape of the first windshield 170 can be selected according to design requirements and can be connected to the first side portion 141 via welding, clipping, bonding, screwing, or other methods. When the fan 310 is activated, without the first windshield 170, air guided by the fan 310 enters through the first opening 141a. Due to the large size of the first opening 141a, contaminants such as dander and hair can easily flow into the skin care device 10 with the airflow, causing malfunction of the skin care device 10. Therefore, in this embodiment, the first windshield 170 is provided at the first opening 141a as a barrier to directly block larger contaminants, reducing contamination and dust accumulation within the skin care device 10 and extending its service life. Furthermore, the gap between the periphery of the first windshield 170 and the edge of the first opening 141a serves as the first air inlet 120, allowing air to evenly enter and exit the device cavity 110 from multiple directions, ensuring sufficient heat dissipation. Preferably, the first windshield 170 can be connected to the first side portion 141 by providing a plurality of connecting columns at the periphery, thereby improving the connection stability and further reducing the probability of pollutants entering.

[0106] The configuration of the second windshield 180 is similar to that of the first windshield 170 and will not be described in detail here.

[0107] like Figure 7 As shown, in some embodiments, the first windshield 170 is detachably connected to the first side portion 141 via a first undercut 171, and the second windshield 180 is detachably connected to the second side portion 142 via a second undercut; and / or,

[0108] The outer surface of the first windshield 170 facing away from the inner cavity 110 is provided with a first silver coating, and the outer surface of the second windshield 180 facing away from the inner cavity 110 is provided with a second silver coating.

[0109] The first inverted buckle 171 and the second inverted buckle make it very convenient to disassemble and install the first wind shield 170 and the second wind shield 180, so that the user can regularly clean the first wind shield 170, the second wind shield 180 and the interior of the skin care device 10, ensuring that the skin care device 10 can operate stably for a long time.

[0110] Silver has excellent corrosion resistance, and the first silver coating protects the first windshield 170 from corrosion from external environmental factors, thereby extending the service life of the first windshield 170 and maintaining the good appearance of the skin care device 10 over time. Silver also has excellent antibacterial properties, which can reduce the growth of bacteria on the outer surfaces of the first windshield 170 and the second windshield 180, thereby improving the hygiene of the skin care device 10.

[0111] like Figure 1 As shown, in some embodiments, the peripheral side portion 140 also includes a fourth side portion 144 arranged corresponding to the third side portion 143, the third side portion 143 and the fourth side portion 144 are arranged along the thickness direction of the skin care device 10, and the first side portion 141 and the second side portion 142 are arranged along the width direction perpendicular to the skin care device 10.

[0112] The thickness direction of the skin care device 10 is the direction perpendicular to the horizontal plane when the user uses the skin care device 10 in a standard holding posture, and the width direction and length direction of the skin care device 10 are perpendicular to the thickness direction, and the width of the skin care device 10 is smaller than the length. Figure 8 The thickness direction of the skin care device 10 is the ZZ' direction, the length direction is the XX' direction, and the width direction is the YY' direction. The first side portion 141 and the second side portion 142 are arranged along the width direction of the skin care device 10, so that the first air inlet 120 and the first air outlet 130 are also located in the width direction of the skin care device 10. Therefore, when the user uses the skin care device 10, the flowing air will not be blown directly towards the user, reducing the possibility of being affected by the user and improving the user experience.

[0113] It is understandable that the skin care device 10 may have a variety of holding postures. In this case, one of the holding postures is selected as the standard holding posture, and the thickness direction of the skin care device 10 is determined accordingly.

[0114] like Figure 1 As shown, in some embodiments, a third air inlet 144 a communicating with the inner cavity 110 is formed at one end of the fourth side portion 144 close to the first end portion 150 .

[0115] The introduction of the third air inlet 144a increases the number of paths for air to enter the inner cavity 110, allowing the heat dissipation assembly 300 to draw air from more directions, thereby improving overall heat dissipation efficiency. Furthermore, positioning the third air inlet 144a at the end of the fourth side portion 144 near the first end 150 allows air to flow from the third air inlet 144a to the second air inlet 311 of the fan 310 over a longer path, traversing a wider area. This results in more uniform heat dissipation across the various components within the inner cavity 110, preventing localized overheating.

[0116] The above description is only part or preferred embodiments of the present invention. Neither the text nor the drawings can limit the scope of protection of the present invention. All equivalent structural transformations made by using the contents of the present invention specification and drawings under the overall concept of the present invention, or direct / indirect application in other related technical fields are included in the scope of protection of the present invention.
