Description
Technical Field
[0001] This application belongs to the technical field of skin treatment devices, and particularly relates to a skin treatment device. Background Art
[0002] Hair removal devices, skin rejuvenation devices, etc. are commonly used skin treatment devices in people's lives. These skin treatment devices mainly irradiate the user's skin with a light source of IPL (intense pulsed light) or laser, so as to achieve effects such as hair removal or photon skin rejuvenation on the user's skin.
[0003] In related designs, a skin treatment device includes a plurality of light sources and a sapphire. The light emitted by the plurality of light sources enters the sapphire from the light incident surface of the sapphire, and then is directed towards the skin. Among them, the plurality of light sources in the skin treatment device often enter the sapphire from different positions on the light incident surface of the sapphire, and then are mixed in the middle of the sapphire and then directed towards the skin. In this way, the light rays emitted by different light sources are difficult to be fully and evenly mixed, and it is easy to cause uneven skin color of the user after being directed towards the skin, affecting the use experience. Utility Model Content
[0004] In view of the above situation, it is necessary to provide a skin treatment device that can improve the uniformity of the emitted light and reduce the possibility of uneven skin color of the user.
[0005] An embodiment of this application provides a skin treatment device, which includes a light transmissive member, a first reflector, a first light source, a second reflector, and a second light source. The light transmissive member includes a light incident surface and a light exit surface that are oppositely arranged along a first direction. The first reflector has a first reflection space and a first light exit, and the first light exit communicates with the first reflection space, and the first light exit faces the light incident surface. The first light source is disposed in the first reflection space, and the light emitted by the first light source is reflected by the first reflector and forms a first area on the light incident surface. The second reflector has a second reflection space and a second light exit, and the second light exit communicates with the second reflection space, and the second light exit faces the light incident surface. The second reflector is disposed on the side of the first reflector. The second light source is disposed in the second reflection space, and the light emitted by the second light source is reflected by the second reflector and forms a second area on the light incident surface. The second area at least partially overlaps with the first area.
[0006] In this skin treatment device, the light emitted by the first light source and the light emitted by the second light source start to be mixed from the light incident surface of the light transmissive member until they are emitted from the light exit surface, which is beneficial to improving the uniformity of the light mixed by the first light source and the second light source, and thus can reduce the possibility of uneven skin color of the user's skin.
[0007] In an alternative embodiment of the present application, the area of the second region overlapping with the first region is S1, and the area of the second region is S2. S1 and S2 satisfy: 55% ≤ S1 / S2 ≤ 100%. S1 / S2 ≥ 55% is conducive to allowing enough light emitted by the second light source to be mixed with the light emitted by the first light source, which is conducive to improving the uniformity of the mixture of the light emitted by the first light source and the light emitted by the second light source. Moreover, as the ratio of S1 / S2 increases, the mixing ratio of the light emitted by the second light source and the light emitted by the first light source increases, and the mixing uniformity improves, which is conducive to further reducing the possibility of uneven skin color of the user caused by uneven light mixing.
[0008] In an alternative embodiment of the present application, the ratio of the area of the first region to the area of the light incident surface is greater than or equal to 0.8 and less than or equal to 1. In this way, the area of the light incident surface covered by the light emitted by the first light source is not too small, which is conducive to increasing the light output area of the light emitted by the first light source on the light transmissive member and improving the efficiency of the user using the skin treatment device to beautify the skin.
[0009] In an alternative embodiment of the present application, the first light source is a lamp tube, the light incident surface is rectangular or square, and the length direction of the lamp tube is the same as the length direction of the light incident surface. In this way, it is conducive to increasing the ratio of the area of the light incident surface covered by the first region to the total area of the light incident surface.
[0010] In an alternative embodiment of the present application, the second light source is annular, and the second light source surrounds the first light source, which is conducive to increasing the area of the light incident surface covered by the light emitted by the first light source and the second light source, and is also conducive to improving the uniformity of the mixture of the first light source and the second light source.
[0011] In an alternative embodiment of the present application, there are multiple second light sources, and the multiple second light sources surround the first light source, which is conducive to increasing the area of the light incident surface covered by the light emitted by the first light source and the second light source.
[0012] In an alternative embodiment of the present application, the second reflector is annular, and the second reflector is arranged to surround the first reflector. The annular second reflector can be adapted to both annular lamps and multiple second light sources surrounding the first light source. Using the annular second reflector to reflect the light emitted by the second light source is conducive to gathering the light towards the light incident surface to improve the light utilization rate.
[0013] In an alternative embodiment of the present application, there are multiple second light sources, and the multiple second light sources surround the first light source; there are multiple second reflectors, and the number of second reflectors is the same as the number of second light sources. Each second light source is arranged in the second reflection space of a second reflector. In this way, the shape of the second reflector can be adjusted adaptively according to the position of each second light source relative to the light incident surface, so that as much light as possible emitted by the second light source can be incident on the light incident surface.
[0014] In an alternative embodiment of the present application, there is a gap between the first light reflector and the second light reflector, and / or when there are multiple second light reflectors, there is a gap between adjacent second light reflectors. The skin treatment device includes a third light reflector that covers the gap. By providing the third light reflector to block at least one of the gap between the first light reflector and the second light reflector and the gaps between adjacent light reflectors, it is beneficial to reduce the possibility that the light emitted by the first light source and the second light source fails to reach the light incident surface, and reduce light leakage.
[0015] In an alternative embodiment of the present application, the first light reflector, the second light reflector, and the third light reflector are integrally provided. In this way, it is beneficial to reduce the processing difficulty of the first light reflector, the second light reflector, and the third light reflector, and it is also beneficial to improve the efficiency of assembling the first light reflector, the second light reflector, and the third light reflector with other structures of the skin treatment device.
[0016] In an alternative embodiment of the present application, the skin treatment device further includes a third light reflector, and the third light reflector is located on the side away from the light transmissive member of the first light reflector and the second light reflector in the first direction. The third light reflector includes a third reflection space and a third light outlet, the third light outlet communicates with the third reflection space, at least a part of the first light reflector and the second light reflector is located in the third reflection space, and the third light outlet faces the light incident surface. In this way, it is beneficial to reduce the possibility that the light emitted by the first light source and the second light source fails to reach the light incident surface, and reduce light leakage.
[0017] In an alternative embodiment of the present application, the light incident surface has a median line perpendicular to the first direction, the median line is located within the projection of the first light source on the light incident surface, and the projection of the second light source on the plane where the light incident surface is located is spaced apart from the median line. The first light source emits light from approximately the middle of the light transmissive member towards the light transmissive member, and the second light source emits light from approximately the edge of the light transmissive member towards the light transmissive member, which is beneficial to increase the area of the light incident surface covered by the light emitted by the first light source and the second light source, thereby improving the efficiency of the user using this skin treatment device to beautify the skin.
[0018] In an alternative embodiment of the present application, the projection of the second light source on the plane where the light incident surface is located is located at the edge of the light incident surface. The first light source emits light from approximately the middle of the light transmissive member towards the light transmissive member, and the second light source emits light from a position close to the edge of the light transmissive member towards the light transmissive member, which is beneficial to increase the area of the light incident surface covered by the light emitted by the first light source and the second light source.
[0019] In an alternative embodiment of the present application, the bottom of the second reflection space is offset in a direction away from the first light source, so that the second light outlet is arranged to face the median line, so that at least a part of the second region coincides with the first region.
[0020] In an alternative embodiment of the present application, the second reflecting member includes a first reflecting surface located on the side of the second light source away from the first light source, a second reflecting surface located on the side of the second light source close to the first light source, and a reflecting arc surface that smoothly connects the first reflecting surface and the second reflecting surface. The first reflecting surface, the second reflecting surface, and the reflecting arc surface enclose a second reflecting space. The first reflecting surface extends substantially along the first direction, and the second reflecting surface is disposed at an inclination to the first direction so as to reflect and converge the light emitted by the second light source onto the light incident surface.
[0021] In an alternative embodiment of the present application, the skin treatment device further includes a light filtering member. Along the first direction, the light filtering member is disposed between the first light source and the light transmissive member. The light emitted by the first light source and the second light source is filtered by the light filtering member and then projected onto the light incident surface. The light filtering surface of the light filtering member is larger than the light incident surface. By providing the light filtering member, the light emitted by the first light source and the second light source can be filtered so that light of a specific wavelength is projected onto the light incident surface to achieve a specific beauty effect.

[0065] Referring to "embodiments" herein means that the specific features, structures or characteristics described in connection with the embodiments can be included in at least one embodiment of the present application. The phrase appears in various places in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment mutually exclusive with other embodiments. Without conflict, the various embodiments in the present application can be combined with each other.
[0066] Embodiments of the present application provide a skin treatment device, which includes a light-transmitting member, a first reflector, a first light source, a second reflector, and a second light source. The light-transmitting member includes a light incident surface and a light exit surface that are oppositely arranged in a first direction. The first reflector has a first reflection space and a first light exit opening. The first light exit opening communicates with the first reflection space and faces the light incident surface. The first light source is disposed in the first reflection space. After the light emitted by the first light source is reflected by the first reflector, a first region is formed on the light incident surface. The second reflector has a second reflection space and a second light exit opening. The second light exit opening communicates with the second reflection space and faces the light incident surface. The second reflector is disposed on the side of the first reflector. The second light source is disposed in the second reflection space. After the light emitted by the second light source is reflected by the second reflector, a second region is formed on the light incident surface. The second region at least partially overlaps with the first region.
[0067] In this skin treatment device, the light emitted by the first light source and the light emitted by the second light source start to mix from the light incident surface of the light-transmitting member until they are emitted from the light exit surface, which is beneficial to improving the uniformity of the mixing of the light emitted by the first light source and the second light source, thereby reducing the possibility of uneven skin color of the user.
[0068] The embodiments of the present application will be further described below with reference to the accompanying drawings.
[0069] As Figure 1 shown, embodiments of the present application provide a skin treatment device 100. The skin treatment device 100 is a device that adjusts and improves the skin state of the body and face according to human physiological functions. In terms of functions, it has functions such as whitening, skin rejuvenation, freckle removal, wrinkle removal, hair removal, etc. Among them, based on optics, different effects can be achieved by irradiating the skin with light of special wavelengths or different types of light. For example, intense pulsed light (IPL), LED light, laser, etc. that are currently widely used.
[0070] In some embodiments, as Figures 2 to 4As shown, the skin treatment device 100 includes a light-transmitting member 10, a first reflector 20, a first light source 30, a second reflector 40, and a second light source 50. The light-transmitting member 10 includes a light-incident surface 11 and a light-emitting surface 12 that are oppositely arranged along a first direction X. The first reflector 20 has a first reflection space 21 and a first light-emitting port 22. The first light-emitting port 22 communicates with the first reflection space 21, and the first light-emitting port 22 faces the light-incident surface 11. The first light source 30 is disposed in the first reflection space 21. After the light emitted by the first light source 30 is reflected by the first reflector 20, a first region 23 is formed on the light-incident surface 11. The second reflector 40 has a second reflection space 41 and a second light-emitting port 42. The second light-emitting port 42 communicates with the second reflection space 41, and the second light-emitting port 42 faces the light-incident surface 11. The second reflector 40 is disposed on the side of the first reflector 20. The second light source 50 is disposed in the second reflection space 41. After the light emitted by the second light source 50 is reflected by the second reflector 40, a second region 46 is formed on the light-incident surface 11. The second region 46 at least partially overlaps with the first region 23.
[0071] It should be noted that the at least partial overlap between the first region 23 and the second region 46 includes the case where the first region 23 and the second region 46 completely overlap. Here, complete overlap does not necessarily mean that the areas of the first region 23 and the second region 46 are equal. In other words, when the first region 23 and the second region 46 completely overlap, the area of the first region 23 and the area of the second region 46 may be equal or may not be equal. When the area of the first region 23 is not equal to the area of the second region 46, as Figure 4 shown, the meaning of their complete overlap is that the smaller one is completely located within the larger one. In addition, although the range of the first region 23 is defined after the light of the first light source 30 is reflected by the first reflector 20 to the light-incident surface 11, however, within the range of the first region 23, it is also possible to include the light emitted by the first light source 30 that is not reflected by the first reflector 20, that is, this part of the light is emitted from the first light source 30 and directly shoots towards the light-incident surface 11; and although the second region 46 is defined after the light of the second light source 50 is reflected by the second reflector 40 to the light-incident surface 11, however, within the range of the second region 46, it is also possible to include the light emitted by the second light source 50 that is not reflected by the second reflector 40, that is, this part of the light is emitted from the second light source 50 and directly shoots towards the light-incident surface 11.
[0072] In this skin treatment device 100, the light emitted by the first light source 30 and the light emitted by the second light source 50 start to mix from the light-incident surface 11 of the light-transmitting member 10 until they are emitted from the light-emitting surface 12, which is beneficial to improving the uniformity of the mixing of the light emitted by the first light source 30 and the second light source 50, thereby reducing the possibility of causing uneven skin color of the user.
[0073] When considering the uniformity of the mixing of the light rays emitted by the first light source 30 and the light rays emitted by the second light source 50, at least the following two aspects need to be considered: First, the distance at which the light rays emitted by the first light source 30 and the light rays emitted by the second light source 50 are mixed in the emission path. In the embodiments of the present application, the light rays emitted by the first light source 30 and the light rays emitted by the second light source 50 start to be mixed at the light incident surface 11 of the light transmissive member 10. Therefore, the distance at which the two are mixed in the emission path can be characterized by the thickness of the light transmissive member 10 along the first direction X. Second, the proportion of the light rays participating in the mixing in the light rays emitted by the first light source 30 and the light rays emitted by the second light source 50. This factor can be characterized by the ratio of the area where the second region 46 coincides with the first region 23 to the total area of the second region 46. The larger the ratio of the area where the second region 46 coincides with the first region 23 to its total area, the larger the ratio of the amount of light rays emitted by the second light source 50 participating in the mixing to its total amount of light rays, and the higher the mixing uniformity of the light rays emitted by the first light source 30 and the second light source 50.
[0074] In some embodiments, the area where the second region 46 coincides with the first region 23 is S1, and the area of the second region 46 is S2, and S1 and S2 satisfy: 55% ≤ S1 / S2 ≤ 100%. S1 / S2 ≥ 55% is beneficial to mixing a sufficient amount of the light rays emitted by the second light source 50 with the light rays emitted by the first light source 30, which is beneficial to improving the mixing uniformity of the light rays emitted by the first light source 30 and the light rays emitted by the second light source 50. And, as the ratio of S1 / S2 increases, the mixing ratio of the light rays emitted by the second light source 50 and the light rays emitted by the first light source 30 increases, and the mixing uniformity improves, which is beneficial to further reducing the possibility of uneven skin color of the user caused by uneven mixing of light rays.
[0075] In some embodiments, the ratio of the area of the first region 23 to the area of the light incident surface 11 is greater than or equal to 0.8 and less than or equal to 1. In this way, the area of the light incident surface 11 covered by the light rays emitted by the first light source 30 is not too small, which is beneficial to increasing the light emitting area of the light rays emitted by the first light source 30 on the light emitting surface 12 of the light transmissive member 10 and improving the efficiency of the user using the skin treatment device 100 to beautify the skin.
[0076] In some embodiments, both the first light source 30 and the second light source 50 can be set as one of a ring-shaped lamp (such as Figure 5 ), a fluorescent tube (such as Figure 6 ) and a spherical lamp (such as Figure 8 ).
[0077] In some embodiments, both the first light source 30 and the second light source 50 can be set as one of a halogen lamp, a pulsed lamp and an LED lamp.
[0078] In some embodiments, one of the first light source 30 and the second light source 50 is set as a halogen lamp to provide an effect of beautifying the skin, and the other is set as a pulsed lamp to provide an effect of hair removal.
[0079] In some embodiments, as Figure 3 and Figure 5 shown, the first light source 30 is a lamp tube, the light incident surface 11 is rectangular or square, and the length direction of the lamp tube is consistent with the length direction of the light incident surface 11. In this way, it is beneficial to increase the ratio of the area of the light incident surface 11 covered by the first area 23 to the total area of the light incident surface 11.
[0080] In some embodiments, as Figure 5 shown, the second light source 50 is annular, and the second light source 50 surrounds the first light source 30, which is beneficial to increasing the area of the light incident surface 11 covered by the light emitted by the first light source 30 and the second light source 50, and is also beneficial to increasing the uniformity of the mixing of the first light source 30 and the second light source 50.
[0081] In some embodiments, as Figures 6 to 8 shown, there are multiple second light sources 50, and the multiple second light sources 50 surround the first light source 30, which is beneficial to increasing the area of the light incident surface 11 covered by the light emitted by the first light source 30 and the second light source 50.
[0082] In some embodiments, as Figure 5 shown, the second reflector 40 is annular, and the second reflector 40 is arranged to surround the first reflector 20. The annular second reflector 40 can be adapted to both annular lamps and multiple second light sources 50 surrounding the first light source 30. Using the annular second reflector 40 to reflect the light emitted by the second light source 50 is beneficial to the convergence of the light towards the light incident surface 11 to improve the utilization rate of the light.
[0083] In some embodiments, as Figures 6 to 8 shown, there are multiple second light sources 50, and the multiple second light sources 50 surround the first light source 30. There are multiple second reflectors 40, and the number of second reflectors 40 is the same as the number of second light sources 50. Each second light source 50 is arranged in the second reflection space 41 of a second reflector 40. In this way, the shape of the second reflector 40 can be adjusted adaptively according to the position of each second light source 50 relative to the light incident surface 11, so that as much light as possible emitted by the second light source 50 can be incident on the light incident surface 11.
[0084] In some embodiments, as Figure 6 and Figure 7 shown, the second light source 50 is a lamp tube, and multiple lamp tubes are arranged to surround the first light source 30. As an exemplary example, the number of the second light sources 50 can be set to four.
[0085] In some embodiments, asFigure 8 As shown, the second light source 50 is a spherical lamp, and a plurality of spherical lamps are arranged around the first light source 30. Specifically, the plurality of spherical lamps are arranged around the circumferential side of the first light source 30 with the geometric center of the first light source 30 as the center of a circle and an equal radius. More specifically, with the geometric center of the first light source 30 as the center of a circle, the central angles of any two adjacent spherical lamps are equal. In this way, it is beneficial to improve the uniformity of the mixing of the light emitted by the first light source 30 and the light emitted by the second light source 50.
[0086] In some embodiments, the Figure 11 As shown, the incident light surface 11 has a central dividing line 111 perpendicular to the first direction X. The central dividing line 111 is located within the projection of the first light source 30 on the incident light surface 11, and the projection of the second light source 50 on the plane where the incident light surface 11 is located is arranged at an interval from the central dividing line 111. Here, the central dividing line 111 refers to an imaginary line passing through the geometric center of the incident light surface 11 and symmetrically bisecting the incident light surface 11, and the intersection points of the central dividing line 111 and the edge of the incident light surface 11 are the endpoints of the central dividing line 111. When the incident light surface 11 has a plurality of central dividing lines 111, the central dividing line 111 arranged at an interval from the second light source 50 specifically refers to the one located within the projection of the first light source 30. As an exemplary example, in this embodiment, the shape of the incident light surface 11 is one of a circle, a rectangle, a square, an isosceles triangle, an equilateral triangle, and a regular polygon. The first light source 30 emits light from the middle of the light-transmitting member 10 to the light-transmitting member 10, and the second light source 50 emits light from the edge of the light-transmitting member 10 to the light-transmitting member 10, which is beneficial to increasing the area of the light-transmitting member 10 covered by the light emitted by the first light source 30 and the second light source 50, thereby improving the efficiency of the user to beautify the skin with this skin treatment device 100.
[0087] In some embodiments, the projection of the second light source 50 on the plane where the incident light surface 11 is located is located at the edge of the incident light surface 11; or, as Figure 9 and Figure 10 ( Figure 10 The position relationship between the light-transmitting member and the second light source is reflected by a dashed line in
[0088] In this embodiment, the projection of the second light source 50 on the plane where the light incident surface 11 is located is at the edge of the light incident surface 11, including the following situations: First, the projection of the second light source 50 on the plane where the light incident surface 11 is located is tangent to the edge of the light incident surface 11; Second, the projection of the second light source 50 on the plane where the light incident surface 11 is located intersects the edge of the light incident surface 11; Third, the distance between the projection of the second light source 50 on the plane where the light incident surface 11 is located and the edge of the light incident surface 11 is less than or equal to 1 cm.
[0089] In some embodiments, as Figure 3 shown, the bottom of the second reflection space 41 is offset in a direction away from the first light source 30, so that the second light outlet 42 is arranged facing the middle dividing line 111, so that the second area 46 at least partially coincides with the first area 23.
[0090] In some embodiments, as Figure 3 shown, the second reflection space 41 includes a first reflection surface 43 on the side of the second light source 50 away from the first light source 30, a second reflection surface 44 on the side of the second light source 50 close to the first light source 30, and a reflection arc surface 45 that smoothly connects the first reflection surface 43 and the second reflection surface 44. The first reflection surface 43, the second reflection surface 44, and the reflection arc surface 45 enclose the second reflection space 41. The first reflection surface 43 extends substantially along the first direction X, and the second reflection surface 44 is arranged at an angle to the first direction X, so as to reflect and converge the light emitted by the second light source 50 onto the light incident surface 11.
[0091] In some embodiments, as Figures 5 to 8 shown, there is a gap between the first light reflecting member 20 and the second light reflecting member 40, and / or when there are multiple second light reflecting members 40, there is a gap between adjacent second light reflecting members 40. The skin treatment device 100 includes a third light reflecting member 60 that covers the gap. By providing the third light reflecting member 60 to block at least one of the gap between the first light reflecting member 20 and the second light reflecting member 40 and the gap between adjacent two light reflecting members, it is beneficial to reduce the possibility that the light emitted by the first light source 30 and the second light source 50 fails to reach the light incident surface 11 and reduce light leakage.
[0092] In some embodiments, as Figure 7 shown, the first light reflecting member 20, the second light reflecting member 40, and the third light reflecting member 60 are integrally provided. In this way, it is beneficial to reduce the processing difficulty of the first light reflecting member 20, the second light reflecting member 40, and the third light reflecting member 60, and it is also beneficial to improve the efficiency of assembling the first light reflecting member 20, the second light reflecting member 40, and the third light reflecting member 60 with other structures of the skin treatment device 100.
[0093] In some embodiments, as Figure 8As shown, the third reflector 60 is located on the side away from the light transmissive member 10 of the first reflector 20 and the second reflector 40 in the first direction X. The third reflector 60 includes a third reflection space 61 and a third light outlet 62. The third light outlet 62 communicates with the third reflection space 61. At least a part of the first reflector 20 and the second reflector 40 is located in the third reflection space 61. The third light outlet 62 faces the incident light surface 11. In this way, it is beneficial to reduce the possibility that the light emitted by the first light source 30 and the second light source 50 fails to be directed towards the incident light surface 11, and reduce light leakage.
[0094] In some embodiments, the light transmissive member 10 is made of sapphire. In other embodiments, the light transmissive member 10 can also be made of other light guiding materials, and the embodiments of the present application do not limit this.
[0095] In some embodiments, as Figure 2 and Figure 3 shown, the skin treatment device 100 further includes a filter member 70. Along the first direction X, the filter member 70 is disposed between the first light source 30 and the light transmissive member 10. The light emitted by the first light source 30 and the second light source 50 is filtered by the filter member 70 and then directed towards the incident light surface 11. The filtering surface of the filter member 70 is larger than the incident light surface 11. By providing the filter member 70, the light emitted by the first light source 30 and the second light source 50 can be filtered, so that light of a specific wavelength is directed towards the incident light surface 11 to achieve a specific beauty effect.
[0096] In some embodiments, the filter member 70 is used to transmit light with wavelengths between 560 nanometers and 1200 nanometers, so as to form IPL within a specific wavelength range to irradiate the user's skin. Generally speaking, the light wavelength required for hair removal can be between 560 nanometers and 1200 nanometers, and the light wavelength required for skin rejuvenation can be between 640 nanometers and 1200 nanometers. The type of the filter member 70 can be selected accordingly.
[0097] In some embodiments, the outer shape of the filter member 70 is adapted to the outer shape of the incident light surface 11 of the light transmissive member 10. For example, when the incident light surface 11 is circular, the filter member 70 is provided as a cylinder; another example is that when the incident light surface 11 is rectangular or square, the filter member 70 is provided as a quadrangular prism.
[0098] In some embodiments, as Figure 1 and Figure 2 shown, the skin treatment device 100 further includes a housing 80. The first light source 30, the second light source 50, the first reflector 20, the second reflector 40, and the light transmissive member 10 are all disposed within the housing 80. The housing 80 is provided with a fourth light outlet 81. The light emitting surface 12 of the light transmissive member 10 is exposed to the outside of the skin treatment device 100 through the fourth light outlet 81.
[0099] In addition, those of ordinary skill in the art should recognize that the above embodiments are merely used to illustrate the present application and are not intended to limit the present application. As long as appropriate changes and variations made to the above embodiments fall within the scope of the spirit of the present application, they are within the scope of disclosure of the present application.
