[0025] In order to make those skilled in the art better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without making creative work are within the scope of protection of the present application.
[0026] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application.
[0027] See also Figure 1 and Figure 2The embodiment of the present application provides a skin treatment device 100, which is a device that adjusts and improves the body and skin conditions according to the physiological functions of the human body. It has the effects of whitening, skin rejuvenation, freckle removal, wrinkle removal, hair removal, etc. Based on optics, different effects can be achieved by irradiating the skin with light of special wavelengths or different types of light. For example, currently, strong pulsed light, LED light, laser, etc. are widely used.
[0028] In some embodiments, the skin treatment device 100 may be a beauty device, for example, the skin treatment device 100 may be a skin rejuvenation device, a hair removal device, or other types.
[0029] In some embodiments, the skin treatment device 100 includes a housing 10 , and the housing 10 is provided with a first ventilation hole 11 , and the first ventilation hole 11 facilitates the air in the housing 10 to circulate with the outside air.
[0030] In some embodiments, the first ventilation hole 11 can be used as an air inlet of the housing 10, so that outside air can enter the housing 10 through the first ventilation hole 11 to dissipate heat for the heating structure of the skin treatment device 100. Alternatively, the first ventilation hole 11 can be used as an exhaust hole of the housing 10, so that the heat in the housing 10 can be discharged to the outside environment through the first ventilation hole 11 to dissipate heat for the heating structure of the skin treatment device 100.
[0031] The embodiment of the present application is described by taking the first ventilation hole 11 as an exhaust hole as an example.
[0032] In some embodiments, the number of the first ventilation holes 11 may be one or more. A plurality of first ventilation holes 11 helps to improve the heat dissipation effect of the housing 10 .
[0033] In the embodiments of the present application, the term "plurality" refers to greater than or equal to two.
[0034] See also Figure 2 and Figure 3 In some embodiments, the heat generation structure of the skin treatment device 100 may include a light output component 20, which may be disposed on the housing 10, and the light output component 20 is used to generate light that is emitted to the skin to be treated through the light output portion of the housing 10. The light output component 20 may include one or more light sources for generating light for treating the skin. The heat generation structure of the skin treatment device 100 may also include a heat pipe, a heat sink, and the like.
[0035] See also Figure 3 and Figure 4In some embodiments, the skin treatment device 100 includes a light shielding and air guiding member 30, which is disposed in the housing 10. The light shielding and air guiding member 30 includes a first section 31 and a second section 32, the first section 31 extends from the first ventilation hole 11 in a direction away from the first ventilation hole 11, the extension direction of the first section 31 forms an angle with the axial direction of the first ventilation hole 11, the second section 32 is connected to one end of the first section 31 away from the first ventilation hole 11, and the second section 32 is biased toward the first ventilation hole 11 relative to the first section 31.
[0036] In this way, the light shielding and air guiding member 30 cooperates with the first ventilation hole 11 to form a curved path, which helps to block the light inside the skin treatment device 100, reduce the risk of light directly leaking out through the first ventilation hole 11, help reduce damage to the eyes of users or other personnel, and improve the safety of the use of the skin treatment device 100. In addition, the light shielding and air guiding member 30 can guide the flow of hot air inside the skin treatment device 100, so that the hot air can flow along the second section 32 and the first section 31 to the first ventilation hole 11 and be discharged from the housing 10 to achieve the purpose of heat dissipation, which not only improves the problem of light leakage and eye damage, but also ensures a good heat dissipation effect inside the skin treatment device 100.
[0037] In some embodiments, the first section 31 and the second section 32 may be an integrally formed structure, for example, the two may be integrally formed by a mold. The junction between the first section 31 and the second section 32 may have a clear boundary line, or the junction between the first section 31 and the second section 32 may have no boundary line or no clear boundary line.
[0038] In some embodiments, the first section 31 can extend linearly, which helps to reduce the structural complexity of the first section 31 and makes the first section 31 easy to process and manufacture. Moreover, since the extension direction of the first section 31 is at an angle to the axial direction of the first ventilation hole 11, the linearly extended first section 31 helps to better block the light inside the skin treatment device 100 from leaking from the first ventilation hole 11.
[0039] In some embodiments, the second section 32 can extend along a curve, which helps to optimize the structural form of the light shielding and wind guiding member 30, which not only helps to block the light inside the skin treatment device 100 from propagating from the first section 31 to the second section 32, but also helps to guide the hot air flow from the first section 31 to the second section 32, helping to enhance the light leakage prevention and wind guiding effects of the light shielding and wind guiding member 30.
[0040] In some embodiments, the second segment 32 may be generally arc-shaped or have other shapes.
[0041] In some embodiments, the end of the second section 32 facing away from the first section 31 has an air guide surface 321, and the air guide surface 321 can be a plane or a convex curved surface. In this way, the air guide surface 321 can strengthen the guiding effect of the second section 32 on the airflow, which helps to enhance the ventilation and heat dissipation effect of the light shielding and air guiding member 30, and the plane air guide surface 321 and the convex curved air guide surface 321 can optimize different ventilation directions, which also helps the second section 32 maintain a good light shielding effect.
[0042] In some embodiments, the number of the light shielding and air guiding members 30 and the number of the first ventilation holes 11 can be multiple. Two adjacent light shielding and air guiding members 30 are spaced apart and distributed on both sides of the radial direction of the same first ventilation hole 11 and define a ventilation channel 33 connected to the first ventilation hole 11, and the extension direction of the ventilation channel 33 is at an angle to the axial direction of the first ventilation hole 11. In this way, multiple light shielding and air guiding members 30 cooperate with each other and are neatly and orderly distributed in the housing 10, which helps to more comprehensively block the leakage of light and helps to enhance the safety of the skin treatment device 100. In addition, while ensuring that the light shielding and air guiding members 30 can block light and guide air, the design method of two adjacent light shielding and air guiding members 30 being spaced apart and distributed on both sides of the radial direction of the same first ventilation hole 11 also helps to reduce the blocking effect of the two adjacent light shielding and air guiding members 30 on the ventilation area of the first ventilation hole 11, and helps the hot air flow entering the ventilation channel 33 to be easily discharged from the first ventilation hole 11 to the outside of the housing 10.
[0043] In some embodiments, when there are multiple light shielding and wind guide members 30, the first section 31 of one or more light shielding and wind guide members 30 extends linearly, and the second section 32 extends along a curve; or, the first section 31 of one or more light shielding and wind guide members 30 extends linearly, and the second section 32 extends linearly; or, the first section 31 of one or more light shielding and wind guide members 30 extends along a curve, and the second section 32 extends linearly; or, the first section 31 of one or more light shielding and wind guide members 30 extends along a curve, and the second section 32 extends along a curve.
[0044] In some embodiments, the width of at least one ventilation channel 33 may gradually increase toward the first ventilation hole 11. In this way, the gradual change design of the ventilation channel 33 helps to increase the area of the ventilation channel 33 while maintaining effective light blocking, thereby helping to enhance the ventilation effect.
[0045] In some embodiments, the distance between at least two adjacent light shielding and air guiding members 30 can gradually increase toward the first ventilation hole 11. In this way, this gradual design also helps to increase the ventilation area between two adjacent light shielding and air guiding members 30 while maintaining effective light shielding, thereby helping to enhance the ventilation effect.
[0046] In some embodiments, the skin treatment device 100 may further include a connector 40, which is located inside the shell 10, and the first section 31 and the second section 32 in the same light shielding and wind guiding member 30 are both connected to the same side of the connector 40, and multiple light shielding and wind guiding members 30 are all located on the same side of the connector 40.
[0047] In this way, by connecting the connecting member 40 and the plurality of light shielding and air guiding members 30 as one body, it helps to improve the stability of the positions of the plurality of light shielding and air guiding members 30 in the housing 10, so that the positions of the plurality of light shielding and air guiding members 30 are not easily moved relative to each other. In addition, the plurality of light shielding and air guiding members 30 are integrated and assembled through the connecting member 40, which simplifies the assembly process of the plurality of light shielding and air guiding members 30 in the housing 10, and there is no need to independently install each light shielding and air guiding member 30 one by one, which effectively saves assembly time and improves production efficiency.
[0048] In some embodiments, the connecting member 40 and the plurality of light shielding and air guiding members 30 may be an integrally formed structure. For example, the connecting member 40 and the plurality of light shielding and air guiding members 30 may be integrally formed by a mold.
[0049] In some embodiments, the connector 40 may be a plate-like structure or other structures.
[0050] See also Figure 1 In some embodiments, the housing 10 may include a first housing 12 and a second housing 13, and the first housing 12 is connected to the second housing 13. One of the first housing 12 and the second housing 13 may serve as a bottom housing, and the other may serve as a top cover. For example, the first housing 12 may serve as a top cover, and the second housing 13 may serve as a bottom housing.
[0051] See also Figure 5 and Figure 6 In some embodiments, the first ventilation hole 11 is provided in the first housing 12, and the light shielding and wind guiding member 30 is provided in the first housing 12. The second housing 13 may include a protective portion 131, and a ventilation space 132 communicating with the outside is provided between the protective portion 131 and the first housing 12, and the ventilation space 132 is communicated with the first ventilation hole 11, and the protective portion 131 covers the first ventilation hole 11 along the axial direction of the first ventilation hole 11. In this way, the protective portion 131 can not only block the light leaking from the first ventilation hole 11, but also effectively guide and discharge the hot air, thereby ensuring good ventilation and heat dissipation.
[0052] In some embodiments, the housing 10 may further be provided with a second ventilation hole 14, and the second ventilation hole 14 facilitates the circulation of air in the housing 10 and the outside air.
[0053] In some embodiments, the second ventilation hole 14 can be used as an air inlet of the housing 10, so that outside air can enter the housing 10 through the second ventilation hole 14 to dissipate heat for the heating structure of the skin treatment device 100. Alternatively, the second ventilation hole 14 can be used as an air outlet of the housing 10, so that the heat in the housing 10 can be discharged to the outside environment through the second ventilation hole 14 to dissipate heat for the heating structure of the skin treatment device 100.
[0054] The embodiment of the present application is described by taking the second ventilation hole 14 as an exhaust hole as an example.
[0055] In some embodiments, the second ventilation hole 14 and the first ventilation hole 11 may be located on different sides of the housing 10. In this way, hot air flows at different positions in the housing 10 are discharged from different sides of the housing 10, which helps to increase the ventilation area of the housing 10 and improve the heat dissipation efficiency.
[0056] In some embodiments, the first ventilation hole 11 may be located on the circumference of the housing 10, and the second ventilation hole 14 may be located on the top of the housing 10. In this way, it is helpful to better utilize the spatial positions of the circumference and top of the housing 10 to arrange the ventilation holes, thereby improving the space utilization of the circumference and top of the housing 10.
[0057] In some embodiments, the skin treatment device 100 may further include a cover body 50, which is disposed outside the shell 10 and covers the second ventilation hole 14 along the axial direction of the second ventilation hole 14, and a ventilation gap 60 connected to the outside is provided between the cover body 50 and the shell 10, and the ventilation gap 60 is connected to the second ventilation hole 14.
[0058] In this way, the cover 50 and the housing 10 cooperate with each other to help block the light inside the skin treatment device 100, reduce the risk of light directly leaking out through the second ventilation hole 14, help reduce damage to the eyes of users or other personnel, and improve the safety of using the skin treatment device 100. In addition, the ventilation gap 60 between the cover 50 and the housing 10 can facilitate the hot air flow at the second ventilation hole 14 to be discharged from the housing 10, and ensure a good heat dissipation effect inside the skin treatment device 100.
[0059] In some embodiments, the cover 50 may be a decorative cover or other structures.
[0060] In some embodiments, the ventilation gap 60 may include a first gap 61 and a second gap 62, wherein the first gap 61 is connected to the second ventilation hole 14 and the second gap 62. A first annular surface 15 and a second annular surface 16 may be provided outside the housing 10, wherein the second ventilation hole 14 passes through the first annular surface 15, the second annular surface 16 surrounds the cover body 50 and is spaced from the cover body 50, the first gap 61 is located between the cover body 50 and the first annular surface 15, and the second gap 62 is located between the cover body 50 and the second annular surface 16.
[0061] In this way, the first gap 61 and the second gap 62 form a multi-level and curved ventilation gap 60, which helps to block the light inside the skin treatment device 100, reduce the risk of light directly leaking out through the second ventilation hole 14, and is beneficial to the dispersion and guidance of airflow, thereby optimizing the heat dissipation effect.
[0062] In some embodiments, when multiple light shielding and air guiding members 30 are connected to the connecting member 40, the connecting member 40 can be connected to the cover body 50 and the housing 10 is sandwiched together with the cover body 50. In this way, the number of light shielding and air guiding members 30 is increased, and they are all connected to the cover body 50 through the connecting member 40, making the structure more stable and reliable, which helps to ensure the stability of the overall operation.
[0063] In some embodiments, the connection between the connector 40 and the cover 50 can be achieved by fasteners such as screws, bolts, etc. In addition, the cover 50 can also be provided with an additional connection structure to achieve connection with the housing 10.
[0064] In some embodiments, the connector 40 may be provided with a notch 41, and the notch 41 may be relatively connected to the second ventilation hole 14 along the axial direction of the second ventilation hole 14. In this way, the position arrangement of the notch 41 not only ensures the ventilation effect, so that the airflow in the housing 10 can flow more smoothly to the second ventilation hole 14, but also ensures that the connection between the connector 40 and the cover 50 is not affected or has no obvious impact, thereby helping to ensure the stability of the overall structure.
