Description

Technical Field

[0001] The utility model relates to the field of beauty care, in particular to a light source component used in a skin treatment device and a skin treatment device. Background Art

[0002] With the development of science and technology, more and more beauty products such as hair removal devices, photon skin rejuvenation devices, beauty devices, etc. are used by people. Most of the existing hair removal devices or photon skin rejuvenation devices on the market use a single light source for hair removal, whitening and other beauty and skin care. Such beauty products generally include a reflective cup and a lamp tube. The single lamp tube is arranged in the reflective cup, and the reflective cup has a reflective surface, and a light outlet is formed on the reflective cup, so that the output energy of the lamp tube is reflected and focused by the reflective surface of the reflective cup. The light energy emitted from the light outlet can meet the requirements of beauty and skin care. The higher the light energy emitted from the light outlet in the beauty product, the better the hair removal effect and the more significant the beauty effect. Therefore, in order to make the beauty effect more significant, the existing beauty products on the market will set multiple lamp tubes in the reflective cup to enhance the light output energy, thereby improving the beauty effect.

[0003] However, since multiple lamp tubes are arranged in the reflective cup, due to the reflective effect of the reflective surface on the reflective cup, the multiple lamp tubes will emit light, and the light emitted by the multiple lamp tubes will interfere with each other. Secondly, when the multiple lamp tubes are arranged in the reflective cup, the multiple lamp tubes will block part of the reflected light from each other, thereby causing the energy of the light emitted by the lamp tube to be weakened, resulting in the final emitted light energy being unable to meet the needs of users.

DETAILED DESCRIPTION

[0038] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are only some embodiments of the utility model, not all embodiments. Based on the embodiments described in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work belong to the protection scope of the utility model.

[0039] It should be noted that all directional indications (such as up, down, left, right, front, back, top, bottom) in the embodiments of the utility model are only used to explain the relative position relationship, movement, etc. between the components under a certain specific posture (as shown in the drawings).

In addition, the term "vertical" involved in the utility model embodiments and claims means that the angle between the two elements is 90° or there is a deviation of -5° to +5°, and the term "parallel" involved means that the angle between the two elements is 0° or there is a deviation of -5° to +5°.

[0040] In the embodiments of the present invention, the descriptions of "first", "second", etc. are only for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" or "second" may explicitly or implicitly include at least one of the features.

[0041] In the embodiment of the present application, the light source assembly 100 is a assembly applied to a skin treatment device 1, and the skin treatment device 1 includes, for example, a hair removal device, a photorejuvenation device, etc., for treating the skin. The light source assembly 100 includes a plurality of light-emitting elements 110, such as two, three, or more than three light-emitting elements 110, etc. In the present embodiment, the plurality of light-emitting elements 110 are described by taking two reflective elements as an example.

[0042] [First embodiment]

[0043] See also Figure 1-Figure 2 The embodiment of the utility model provides a light source assembly 100 applied to a skin treatment device, which includes: a plurality of light-emitting elements 110 and a reflective element 120.

[0044] Specifically, in this embodiment, the plurality of light emitting elements 110 are described by taking two light emitting elements 110 as an example, that is, in this embodiment, the two light emitting elements include a first light emitting element 110a and a second light emitting element 110b. This description does not limit the embodiments of the present application. The first light emitting element 110a and the second light emitting element 110b are, for example, IPL lamps or halogen lamps that can emit intense pulsed light.

[0045] The reflector 120 has a light outlet 1201, and the light outlet 1201 is used to emit the light emitted by the light emitting member 110. In this embodiment, the first light emitting member 110a and the second light emitting member 110b are arranged in the reflector 120 at intervals. The reflector 120 is also provided with a protrusion 121 extending toward the gap between the first light emitting member 110a and the second light emitting member 110b. The reflector 120 is, for example, a reflective cup, and the front end of the outlet of the reflective cup is, for example, a light outlet channel, and the light emitted by the light emitting member 110 arranged in the reflector 120 can be emitted from the light outlet channel to the light outlet 1201, and then emitted from the light outlet 1201 to the human skin.

[0046] In this embodiment, the protrusion 121 is a component protruding from the reflective side of the reflector 120 toward the light outlet 1201. For example, the reflector 120 includes two reflective surfaces, such as a third reflective surface and a fourth reflective surface. When there is no protrusion, the third reflective surface and the fourth reflective surface can be the same reflective surface. When there is a protrusion, the reflective surface on the reflector will be divided into two reflective surfaces. The protrusion 121 can protrude from any position on the two spaced reflective surfaces toward the light outlet 1201.

[0047] Since the prior art places multiple lamp tubes in a reflective cup, the light emitted by the multiple lamp tubes will interfere with each other and the multiple lamp tubes will block part of the reflected light from each other, thereby causing the energy of the light emitted by the lamp tubes to be weakened, the embodiment of the utility model provides a protrusion 121 extending from the gap between the first light-emitting component 110a and the second light-emitting component 110b in the reflective component 120, so that the light generated by the first light-emitting component 110a and the second light-emitting component 110b in the reflective component 120 will not block each other and the light generated by the first light-emitting component 110a and the second light-emitting component 110b will not interfere with each other, thereby ensuring that the light energy generated by the first light-emitting component 110a and the second light-emitting component 110b will not be weakened, thereby further improving the light output energy of the light source assembly 100, improving the beauty effect, and meeting the needs of users.

[0048] In one embodiment of the present application, Figure 1-Figure 2 As shown, the reflector 120 includes a reflective side 1202 facing the first light-emitting member 110a and the second light-emitting member 110b and a heat dissipation side 1203 away from the first light-emitting member 110a and the second light-emitting member 110b, and the protrusion 121 includes a first reflective surface 1211 and a second reflective surface 1212 arranged on the reflective side 1202, and the first reflective surface 1211 and the second reflective surface 1212 are arranged opposite to each other. The first reflective surface 1211 and the second reflective surface 1212 correspond to the first light-emitting member 110a and the second light-emitting member 110b, respectively, and the first reflective surface 1211 and the second reflective surface 1212 do not correspond to the same light-emitting member. That is, the first reflective surface 1211 and the second reflective surface 1212 are respectively arranged on both sides of the protrusion 121. In this embodiment, by setting the first reflecting surface 1211 and the second reflecting surface 1212 on the protrusion 121, the reflection area of ​​the first light-emitting component 110a and the second light-emitting component 110b on the reflective component 120 can be increased. Compared with the prior art of setting multiple light-emitting components in a reflective cup, the design of the present application can increase the reflection area of ​​each light-emitting component 110, improve the light output energy of each light-emitting component 110, and achieve the effect of improving the light output energy.

[0049] like Figure 1-Figure 2As shown, the reflective member 121 also includes a third reflective surface 122 and / or a fourth reflective surface 123 arranged on the reflective side 1202, the third reflective surface 122 and the fourth reflective surface 123 are arranged on the reflective member 120 at intervals, the third reflective surface 122 corresponds to the first light-emitting member 110a, and the fourth reflective surface 123 corresponds to the second light-emitting member; one end of the first reflective surface 1211 is connected to the third reflective surface 122 and corresponds to the first light-emitting member 110a; one end of the second reflective surface 1212 is connected to the fourth reflective surface 123 and corresponds to the second light-emitting member 110b. The other end of the first reflecting surface 1211 away from the third reflecting surface 122 is connected to the other end of the second reflecting surface 1212 away from the fourth reflecting surface 123; the other end of the first reflecting surface 1211 and the other end of the second reflecting surface 1212 both extend toward the gap between the first light-emitting component 110a and the second light-emitting component 110b.

[0050] In a preferred embodiment of this embodiment, if Figure 1-Figure 2 As shown, the reflector 120 is provided with a first reflective cavity 124 and / or a second reflective cavity 125, the first reflective surface 1211 is connected with the third reflective surface 122 to form the first reflective cavity 124; the second reflective surface 1212 is connected with the fourth reflective surface 123 to form the second reflective cavity 125; the first reflective cavity 124 is provided with a first light-emitting element 110a; the second reflective cavity 125 is provided with a second light-emitting element 110b. The reflective surface of the raised portion 121 is connected with the reflective surface on the reflector to form a plurality of reflective cavities, the raised portion 121 can prevent the light emitted by the first light-emitting element 110a in the first reflective cavity 124 from being emitted to the second light-emitting element 110b in the second reflective cavity 125, and the light emitted by the first light-emitting element 110a after being reflected from the first reflective surface 1211 and the third reflective surface 123 will not be reflected to the second light-emitting element 110b. In this embodiment, the first reflective cavity 124 semi-surrounds the first light-emitting element 110a, and the second reflective cavity 125 semi-surrounds the second light-emitting element 110b. That is, the reflective element 120 may include a plurality of reflective cavities, and the plurality of reflective cavities are semi-enclosed structures, and the plurality of reflective cavities can be obtained by connecting or by an integrated molding process. In this embodiment, two light-emitting elements are used as an example for explanation, that is, a structure composed of two semi-enclosed reflective cavities, that is, a reflective element with a W-shaped structure. When there are more than three reflective cavities, the structure of the reflective element can be regarded as a combined structure formed by connecting a plurality of semi-enclosed or U-shaped structures, which is not limited here.

[0051] In a preferred embodiment of this embodiment, if Figure 1-Figure 3As shown, the reflector 120 has a first end 1204 and a second end 1205 corresponding to the first end 1204 , and the light outlet 1201 is formed between the first end 1204 and the second end 1205 .

[0052] In a preferred embodiment of this embodiment, if Figure 1-Figure 2 As shown, the reflector 120 is formed with a heat dissipation area 1206 on the heat dissipation side 1203, and the heat dissipation area 1206 extends from the first end 1204 or the second end 1205 to the protrusion 121. In this embodiment, the heat dissipation area 1206 is, for example, a heat dissipation area of ​​the heat dissipation side. Since the reflector 120 is W-shaped, the heat dissipation area 1206 on the heat dissipation side 1203 is also W-shaped and closely attached to the reflector 120. At this time, the heat dissipation area is relatively increased, thereby improving the heat dissipation effect of the reflector 120.

[0053] Furthermore, if Figure 3As shown, the distance from the protrusion 121 to the first end 1204 is L1, and the distance from the protrusion 121 to the second end 1205 is L2. The ratio range of L1 and L2 is 0.2-0.9. In one embodiment, the ratio of L1 to L2 is 0.2; in another embodiment, the ratio of L1 to L2 is 0.9; preferably, the ratio of L1 to L2 is 0.75. In this embodiment, the ratio range of L1 to L2 is limited so that the area of ​​light emitted by the first light-emitting element 110a is different from the area of ​​light emitted by the second light-emitting element 110b. When the user selects only the first light-emitting element 110a or the second light-emitting element 110b to work alone through mode selection, the ratio range of this distance can also meet different requirements for light output energy when the first light-emitting element 110a or the second light-emitting element 110b works alone. When the user selects multiple light-emitting components 110 to work simultaneously, the energy of the light emitted by the multiple light-emitting components 110 is mixed and emitted from the light outlet through this ratio range, so that the energy of the light emitted by the multiple light-emitting components 110 can meet the preset light energy required for hair removal or whitening and other skin treatments after mixing, so as to improve the light output energy of the light source assembly 100 and enhance the beauty effect. Secondly, the embodiment of the present application sets the ratio range of L1 and L2. When the difference in the ratio range is larger, for example, when the ratio range is 0.2, it means that the area of ​​the light outlet corresponding to the first light-emitting component 110a is much smaller than the area of ​​the light outlet corresponding to the second light-emitting component 110b. The light output area of ​​the first light-emitting component 110a is reduced, and the light emitted by the first light-emitting component 110a will be more concentrated, thereby improving the light concentration and increasing the energy of the light output. When the ratio range difference is smaller, for example, when the ratio range is 0.9, the area of ​​the light outlet corresponding to the first light-emitting component 110a is not much different from the area of ​​the light outlet corresponding to the second light-emitting component 110b. At this time, the light emitted by the first light-emitting component 110a and the light emitted by the second light-emitting component 110b are more uniform at the corresponding light outlets, thereby improving the light uniformity of the light source assembly.

[0054] In a preferred embodiment of this embodiment, if Figure 4-Figure 5 As shown, the light source assembly 100 also includes a filter 130, and the filter 130 is arranged on the light outlet 1201 and connected to the first end 1204 and the second end 1205. The filter 130 is a filter. In some embodiments, the filter can be obtained by optical coating on an optical substrate, and the optical coating process can be evaporative deposition, ion beam sputtering (IBS), plasma sputtering, atomic layer deposition (ALD), etc. For example, the filter can be a single-interval band coating or the filter can be a dual-interval band coating or a partition coating on the same optical substrate, such as a partition filter with zone A and zone B. In this embodiment, the filter can use a filter of the prior art. Different band treatment effects for different skin problems can be achieved by switching different filters, which are not specifically limited here.

[0055] In this embodiment, the height of the raised portion 121 may be, for example, 1mm-10mm. In some embodiments, the height of the raised portion 121 may be, for example, 1mm. In other embodiments, the height of the raised portion 121 may be, for example, 5mm. In yet another embodiment, the height of the raised portion 121 may be, for example, 10mm.

[0056] In this embodiment, the protrusion 121 is disposed between the first end 1204 and the second end 1205, and the height h of the protrusion 121 is equal to the height H of the second end 1205 extending toward the light outlet 1201. In this embodiment, the height of the first end 1204 extending toward the light outlet 1201 is equal to the height of the second end 1205 extending toward the light outlet 1201. The height of the first end 1204 or the height of the second end 1205 can be taken, and the specific details are not limited here. Figure 4-Figure 5 As shown, when the height h of the protrusion 121 is equal to the height H of the second end 1205 extending toward the light outlet 1201 , the protrusion 121 abuts against the filter 130 .

[0057] When the protrusion 121 abuts against the filter 130, the protrusion 121 can divide the light outlet 1201 into a first light outlet and a second light outlet, the first light outlet corresponds to the first light emitting element 110a, and the second light outlet corresponds to the second light emitting element 110b. Figure 3As shown, the spacing L1 is the length of the first light outlet, and the spacing L2 is the length of the second light outlet. At this time, the ratio of L1 to L2 can be replaced by the ratio of the length of the first light outlet to the length of the second light outlet. In this embodiment, by setting the height h of the protrusion 121 not higher than the height H of the second end 1205 extending toward the light outlet 1201, the reflective effect of the multiple light-emitting elements 110 arranged in the reflector 120 and the light mixing effect between the multiple light-emitting elements 110 can be adjusted. When it is necessary to improve the reflective effect of the reflector 120, the height h of the protrusion 121 can be set to be consistent with the height H of the second end 1205 extending toward the light outlet 1201, so that the reflective surface on the protrusion 121 is combined with the reflective surface on the reflector 120, so that the light generated by the light-emitting element 110 will not irradiate the position of other light-emitting elements, thereby improving the reflective effect of the reflector 120, and then improving the light output energy of a single light-emitting element 110. When it is necessary to enhance the light mixing effect of the reflector 120, the height h of the raised portion 121 can be set to be lower than the height H extending from the second end 1205 toward the light outlet 1201, so that part of the light generated by the first light-emitting component 110a is irradiated onto the position of the second light-emitting component 110b, so that the light generated by the second light-emitting component 110b is mixed with the light generated by the first light-emitting component 110a, thereby enhancing the mixed light output effect and further enhancing the light output energy when multiple light-emitting components 110 work simultaneously.

[0058] [Second embodiment]

[0059] In this embodiment, the structure of the light source assembly is substantially the same as that of the light source assembly in the first embodiment, except that a height h of the protrusion 121 is lower than a height H of the second end 1205 extending toward the light outlet 1201 .

[0060] Specifically, Figure 6 As shown, when the height h of the protrusion 121 is lower than the height H of the second end 1205 extending toward the light outlet 1201, the protrusion 121 does not abut against the filter 130. At this time, the length of the first light outlet corresponding to the first light-emitting element 110a is actually greater than the length from the protrusion 121 to the first end 1204 when the protrusion 121 abuts against the filter 130. In this embodiment, the lengths of the first light outlet and the second light outlet cannot be divided by the protrusion 121. At this time, the ratio of the spacing L1 from the protrusion 121 to the first end 1204 to the spacing L2 from the protrusion 121 to the second end 1205 can be directly used instead.

[0061] [Third embodiment]

[0062] like Figure 7-Figure 9As shown, this embodiment provides a skin treatment device 1 , which includes, for example: a housing 800 , a light source assembly 100 and a light-transmitting member 200 .

[0063] The light source assembly 100 is the light source assembly 100 as described in any one of the above embodiments 1 to 2; the light source assembly 100 is arranged in the housing 800. The light-transmitting member 200 is arranged corresponding to the light source assembly 100, and the light generated by the light source assembly 100 is emitted outward after passing through the light-transmitting member 200. The light-transmitting member 200 can be arranged in the housing 800, or part of the light-transmitting member 200 is exposed on the surface of the housing 800, or the light-transmitting member 200 is arranged on the surface of the housing 800, and the light-transmitting member 300 can be arranged in the housing 800 or on the housing 800 according to actual conditions, or part of it is arranged in the housing 800, which is not limited here.

[0064] like Figure 7-10 As shown, the skin treatment device 1 further includes, for example, a mounting bracket 500 disposed in the housing 800, the mounting bracket 500 having an air duct 506, and the light source assembly 100 is located in the air duct 506; the housing 800 is provided with a vent 803, the vent 803 is connected to the air duct 506, and by providing the mounting bracket 500 and arranging the light source assembly 100 in the air duct 506, the light source assembly 100 can be cooled by the vent 506 being connected to the air duct 506. In this embodiment, the mounting bracket 500 is, for example, a housing bracket, which can be composed of an upper housing bracket and a lower housing bracket, and the mounting bracket 500 is formed by connecting the upper housing bracket and the lower housing bracket.

[0065] In a preferred embodiment of this embodiment, if Fig. 9As shown, the reflector 120 includes a reflective side 1202 facing the light emitting element 110 and a heat dissipation side 1203 away from the light emitting element 110. The reflector 120 divides the air duct 506 into a first air duct 5061 and a second air duct 5062, wherein the first air duct 5061 corresponds to the plurality of light emitting elements 110 and is located between the reflective side 1202 and the inner wall of the mounting bracket 500, and the second air duct 5062 is located between the heat dissipation side 1203 and the inner wall of the mounting bracket 500. In this embodiment, the inner wall of the mounting bracket 500 includes a bottom inner wall, a top inner wall opposite to the bottom inner wall, and a left inner wall and a right inner wall arranged between the bottom inner wall and the top inner wall. The first air duct 5061 is located between the reflective side 1202 and the top inner wall of the mounting bracket 500, and the second air duct 5062 is located between the heat dissipation side 1203 and the bottom inner wall of the mounting bracket 500. That is, the reflective element 120 divides the air duct 506 into upper and lower air ducts, the first air duct 5061 is the upper air duct, and the second air duct 5062 is the lower air duct.

[0066] In a preferred embodiment of this embodiment, if Figure 8-Figure 9 As shown, the skin treatment device 1 further includes, for example, a heat dissipation portion 140 , and the heat dissipation portion 140 is located in the second air duct 5062 , and the heat dissipation portion 140 is used to dissipate the heat of the heat dissipation side 1203 .

[0067] Specifically, the heat dissipation portion 140 is formed with a plurality of heat dissipation gaps 1401 in the second air duct 5062 , and the plurality of heat dissipation gaps 1401 are used to dissipate the heat of the heat dissipation side 1203 .

[0068] Furthermore, the heat dissipation side 1203 is formed with a heat dissipation area 1206, and the heat dissipation portion 140 includes a support member 141, and the support member 141 is located between the heat dissipation side 1203 and the inner wall of the bottom side of the mounting bracket 500. There are multiple support members 141, and the heat dissipation gap 1401 can be formed between any two adjacent support members 141 and the heat dissipation area 1206. When the heat generated by the light-emitting member 100 in the reflector 120 when emitting light reaches the heat dissipation side 1203 of the reflector 120, the heat generated by the light-emitting member can be dissipated by setting the heat dissipation gap 1401, thereby achieving the purpose of heat dissipation for the reflector.

[0069] like Fig.10As shown, the heat dissipation part 140 further includes a support member 141, and the support member 141 includes a first support member 142 and a second support member 143. The second support members 143 are distributed on both sides of the first support member 142, and the first support member 142 is connected to the protrusion 121. The height of the second support member 143 is lower than the height of the first support member 142. The second support member 143 is connected to other areas of the reflector 120 except the protrusion 121.

[0070] Furthermore, if Figure 9-10 As shown, the first support member 142 and the second support member 143 are matched with the reflector 120. The first support member 142 and the second support member 143 each include an end 144 close to the reflector 120, and a curved surface 1441 is formed on the end 144, and the curved surface 1441 is matched with the reflector 120. As can be seen from the first embodiment described above, the reflector 120 in this embodiment is a reflector 120 of a W-shaped structure, that is, the heat dissipation side 1203 on the reflector 120 is arranged in an arc shape, a semicircle, or a semi-ellipse. The first support member 142 and the second support member 143 need to be adapted to the reflector 120, and the end surfaces of the first support member 142 and the second support member 143 on the end portion close to the reflector 120 must be in contact with the heat dissipation side 1203 on the reflector 120. When the heat dissipation side 1203 on the reflector 120 is arranged in an arc shape, a semicircle, or a semi-ellipse, the end surface formed on the end portion is an arc surface 1441. Fig.10 It can be seen that the second support members 143 on the left side of the first support member 142 are arranged at intervals, and the arc surface of each second support member 143 is different. This is because the positions where the second support members 143 contact the reflector 120 are different. When the structure of the reflector 120 is set in a parabolic structure, the arc surface 1441 in the second support member 143 is arranged in an arc setting that first descends and then rises. That is, the arc shape of the arc surface 1441 in the present application changes according to the change of the specific shape structure of the reflector 120. Through such a setting, the support member 141 and the reflector 120 are perfectly matched and connected, thereby achieving the effect of fixing and heat dissipation, and improving the assembly efficiency and heat dissipation efficiency of the skin treatment device 1.
