Description

Technical Field

[0001] This application belongs to the field of beauty equipment, and in particular relates to a skin care device. Background Technology

[0002] Hair removal devices and phototherapy devices are commonly used skin care equipment in people's lives. These skin care devices mainly use light-emitting components such as IPL (intense pulsed light) light sources to irradiate the user's skin from the light-emitting surface of the casing, thereby achieving effects such as hair removal and phototherapy.

[0003] In related technologies, taking hair removal devices as an example, the light emitted from different parts of the light-emitting surface is not uniform in brightness, which leads to inconsistent skin care effects on different parts of the skin, ultimately resulting in poor skin care effects from the skin care device.

[0021] The space between the power-collecting component and the conductive bracket is filled with conductive material; and / or, there is a positioning contact between the power-collecting component and the inner wall of the mounting slot to position the power-collecting component.

[0022] In some embodiments, along the direction of the first plane, the maximum distance between at least one inner wall of the mounting slot and the outer surface of the power-collecting component does not exceed 0.5 mm;

[0023] Alternatively, at least a portion of the inner wall of the mounting slot and the outer periphery of the power-collecting component have a reserved gap, the maximum distance of the reserved gap not exceeding 0.5mm;

[0024] Alternatively, the width of the mounting slot is 1.05 to 1.3 times the outer diameter of the power-collecting component;

[0055] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0056] In the first aspect, embodiments of this application provide a skin care device, which may be a hair removal device or a skin rejuvenation device, or any other skin care device. Embodiments of this application do not limit the specific type of skin care device.

[0057] Please refer to Figure 1 and Figure 2 The skin care device may include a housing 100, a filter 200, and a light-emitting assembly 300. The housing 100 has a light-emitting port 11. The filter 200 is positioned near the light-emitting port 11 and allows light of a preset wavelength to pass through. The light-emitting assembly 300 is disposed within the housing 100. The light-emitting assembly 300 includes at least two lamps 31, which define a first plane P1. The angle between the filter 200 and the first plane P1 does not exceed 45°. The lamps 31 operate at a voltage of 270V to 450V to generate light that is directed towards the filter 200. The light generated by the lamps 31 and filtered by the filter 200 can be directed from the light-emitting port 11 onto the skin to be treated.

[0058] In this embodiment, the light-emitting component 300 has at least two lamps 31, enabling it to perform skincare at a higher maximum power, thereby improving the skincare effect of the device. Furthermore, since the angle between the first plane P1 defined by the at least two lamps 31 and the filter 200 is controlled to not exceed 45°, the light emitted by the lamps 31 at the first plane P1 is filtered by the filter 200, resulting in more uniform brightness across the surface, ultimately enhancing the skincare effect of the device.

[0059] For example, the angle between the filter 200 and the first plane P1 can be 0°, 0.7°, 2.7°, 3.1°, 3.5°, 4°, 4.22°, 4.5°, 5°, 7.8°, 9.5°, 10°, 14.05°, 15°, 20°, 21.6°, 25°, 30°, 34.6°, 39°, 40°, 40.5°, 43.2°, 44°, or 45°. This application embodiment does not limit this.

[0060] In some embodiments, the relative deflection angle between the filter 200 and the first plane P1 does not exceed 5°, thereby making the filter 200 and the first plane P1 approximately parallel. Consequently, the light generated by the lamp 31 at the first plane P1 becomes more uniformly bright after being filtered by the filter 200, ultimately improving the skin care effect of the skin care device.

[0061] Please continue to refer to this. Figure 3 It can also be understood that, taking the thickness direction of the filter 200 as extending horizontally as an example, the lower edge of the filter 200 may be deflected (or tilted) towards the first plane P1, so that the filter 200 and the first plane P1 have a relative deflection angle; the lower edge of the filter 200 may be deflected (or tilted) away from the first plane P1, so that the filter 200 and the first plane P1 have a relative deflection angle; and the front edge of the filter 200 may be deflected (or tilted) towards the first plane P1, so that the filter 200 and the first plane P1 have a relative deflection angle; of course, the front edge of the filter 200 may also be deflected (or tilted) away from the first plane P1, so that the filter 200 and the first plane P1 have a relative deflection angle, and the embodiments of this application do not limit this.

[0062] In some embodiments, the filter 200 is capable of allowing light with wavelengths from 600 nm to 1100 nm to pass through.

[0063] It is understood that the wavelength of light required for hair removal is between 420nm and 1200nm, while the wavelength of light required for skin rejuvenation is between 600nm and 1200nm. Therefore, the filter 200 of this application embodiment allows light with a wavelength of 600nm to 1100nm to pass through, which can meet both the skin rejuvenation and hair removal needs of the skin to be treated.

[0064] In some embodiments, the lamp tube 31 is in the shape of a straight strip, and at least two lamp tubes 31 extend in the same plane, with the first plane P1 defined by the central axis of the at least two lamp tubes 31.

[0065] It is understood that the number of lamps 31 can be at least three, such as three, four, five, or even ten lamps 31. This application embodiment does not limit this. Therefore, it is possible that only two of the lamps 31 are located in the same plane, thereby determining the first plane P1 by the central axis of the two lamps 31, or it is possible that three, four, five, or even all the lamps 31 extend in the same plane. This application embodiment does not limit this.

[0066] In some embodiments, there are two lamp tubes 31, which are parallel to each other, and a first plane P1 is formed by the central axis of the two lamp tubes 31.

[0067] Furthermore, by setting the number of lamp tubes 31 to two, the light-emitting component 300 can use two lamp tubes 31 to perform skin care at a higher maximum power, thereby improving the skin care effect of the skin care device. At the same time, it can avoid excessive heat generated by the light-emitting component 300 when it is working due to an excessive number of lamp tubes 31, thereby avoiding safety hazards when the light-emitting component 300 is working.

[0068] In some embodiments, the closest distance D1 between two adjacent lamp tubes 31 is not less than 1 mm, thereby preventing the large amount of heat generated by the lamp tubes 31 during operation from interfering with the adjacent lamp tubes 31 by avoiding excessively close distance between them. Of course, a sufficiently large gap can also be made between two adjacent lamp tubes 31 to form electrical isolation.

[0069] It should be noted that the closest distance D1 between two adjacent lamp tubes 31 is the straight-line distance between the closest positions of the two adjacent lamp tubes 31.

[0070] For example, the closest distance D1 between two adjacent lamp tubes 31 is 1mm, 1.42mm, 1.5mm, 1.8mm, 2mm, 2.3mm, 2.41mm, 2.5mm, 2.9mm, 3mm, 3.14mm, 3.5mm or 4mm, and this application embodiment does not limit this.

[0071] In some implementations, the closest distance D1 between two adjacent lamp tubes 31 is not less than 2mm, so as to achieve a better isolation effect between the two adjacent lamp tubes 31.

[0072] Please continue to refer to this. Figure 4 In some embodiments, the skin care device also includes a conductive component 41, which is connected to the lamp tube 31 and provides an operating voltage to the lamp tube 31.

[0073] For example, the skin care device may also include a circuit board assembly 400, which includes a circuit board 42 and a conductive component 41, the conductive component 41 being mounted on the circuit board 42 to form an electrical connection. Furthermore, the lamp tube 31 can be electrically connected to the circuit board 42 via the conductive component 41.

[0074] Understandably, as mentioned above, the operating voltage is between 270V and 450V. This avoids both insufficient voltage, which would result in low light brightness from the lamp 31, and excessive voltage, which would cause excessive heat to be generated and affect adjacent lamps 31. Furthermore, by setting the operating voltage to between 270V and 450V, the treatment effect of the light-emitting assembly 300 on the skin being treated can be improved.

[0075] For example, the operating voltage is 270V, 274V, 278V, 280V, 285V, 286.7V, 290V, 293V, 300V, 307.6V, 310V, 310.07V, 320V, 325V, 333.8V, 335V, 340V, 343V, 350V, 378V, 380V, 380.9V, 395V, 400V, 412V, 423V, 435V, 447V, or 450V. This application embodiment does not limit this.

[0076] In some embodiments, the operating voltage of the light-emitting component 300 is 280V to 350V, which can improve the skin care effect of the light-emitting component 300 on the treated skin.

[0077] In some embodiments, the conductive component 41 includes a conductive bracket with a mounting slot 411, and the lamp tube 31 has a power-taking component 311 that can be snapped into the mounting slot 411. Therefore, during the production and assembly of the skin care device, simply snapping the power-taking component 311 into the mounting slot 411 can achieve the connection, fixation, or initial positioning between the lamp tube 31 and the conductive component 41.

[0078] In some embodiments, a conductive material (not shown) is filled between the power-taking component 311 and the conductive support.

[0079] Furthermore, by using conductive materials, the electrical connection area between the power-taking component 311 and the conductive bracket can be increased, thereby providing the current-carrying capacity between the conductive bracket and the power-taking component 311. In turn, on the one hand, the current transmission efficiency between the conductive bracket and the power-taking component 311 can be improved, and on the other hand, the safety hazards caused by overheating at the connection point due to the small overcurrent area between the conductive bracket and the power-taking point can be avoided.

[0080] It should be noted that conductive material may be provided in a portion of the periphery of the power-taking component 311, or conductive material may be provided in the entire periphery of the power-taking component 311. This application embodiment does not limit this.

[0081] In some embodiments, there is a positioning contact between the power receiving component 311 and the inner wall of the mounting slot 411 to position the power receiving component 311. Furthermore, during the installation of the lamp tube 31, the inner wall of the mounting slot 411 can effectively position the power receiving component 311 (or the lamp tube 31), thereby facilitating accurate control of the angular deviation between the first plane P1 formed by the lamp tube 31 and the filter 200.

[0082] It is understood that the area of ​​the inner wall of the mounting slot 411 away from the opening may have a positioning contact with the power receiving component 311, or the area of ​​the inner wall of the mounting slot 411 near the opening may have a positioning contact with the power receiving component 311, or multiple areas of the inner wall of the mounting slot 411 may have a positioning contact with the power receiving component 311. This application embodiment does not limit this.

[0083] Please continue to refer to this. Figure 5 In some embodiments, the width of the mounting slot 411 is 1.05 to 1.3 times the outer diameter of the power-taking component 311. This avoids the problem of the power-taking component 311 being difficult to install if the width of the mounting slot 411 is too small, and also avoids the problem of the power-taking component 311 being poorly fixed if the width of the mounting slot 411 is too large.

[0084] In some embodiments, the width of the mounting slot 411 is 1.05 to 1.2 times the outer diameter of the power-taking component 311. This avoids the problem of the power-taking component 311 being difficult to install if the width of the mounting slot 411 is too small, and also avoids the problem of the power-taking component 311 being poorly fixed if the width of the mounting slot 411 is too large.

[0085] For example, the width of the mounting slot 411 is 1.2 times, 1.206 times, 1.21 times, 1.235 times, 1.27 times, 1.289 times, 1.29 times, 1.295 times, or 1.3 times the outer diameter of the power taking part 311. This application embodiment does not limit this.

[0086] In some embodiments, along the direction of the first plane P1, the maximum distance D2 between at least one inner wall of the mounting slot 411 and the outer surface of the power-receiving component 311 does not exceed 0.5 mm. This avoids, on the one hand, excessive gaps between the inner wall of the mounting slot 411 and the power-receiving component 311, which could lead to unstable installation of the power-receiving component 311; and on the other hand, it avoids excessive gaps between the inner wall of the mounting slot 411 and the power-receiving component 311, which could reduce the current transmission performance between the power-receiving component 311 and the conductive support.

[0087] For example, along the direction of the first plane P1, the maximum distance D2 between at least one inner wall of the mounting slot 411 and the outer surface of the power-taking component 311 is 0.05 mm, 0.1 mm, 0.13 mm, 0.15 mm, 0.176 mm, 0.19 mm, 0.2 mm, 0.237 mm, 0.25 mm, 0.265 mm, 0.27 mm, 0.29 mm, 0.3 mm, 0.36 mm, 0.37 mm, 0.4 mm, 0.45 mm, or 0.5 mm. This application embodiment does not limit this.

[0088] In some embodiments, the maximum distance D2 between the inner wall of at least one side of the mounting slot 411 and the outer side of the power-taking component 311 along the direction of the first plane P1 does not exceed 0.3 mm.

[0089] It should also be noted that, along the direction of the first plane P1, the maximum distance D2 between the inner wall of the mounting slot 411 and the outer side of the power-taking component 311 is the straight-line distance between the inner wall of the mounting slot 411 and the outer side of the power-taking component 311 at a distance from each other.

[0090] In some embodiments, a reserved gap 411a exists in at least a portion of the area between the inner wall of the mounting slot 411 and the outer periphery of the power-receiving component 311, with the maximum distance of the reserved gap 411a not exceeding 0.5 mm. This avoids, on the one hand, the instability of the power-receiving component 311 due to an excessively large gap between the inner wall of the mounting slot 411 and the power-receiving component 311; and on the other hand, it avoids a reduction in the current transmission performance between the power-receiving component 311 and the conductive support due to an excessively large gap between the inner wall of the mounting slot 411 and the power-receiving component 311.

[0091] For example, the maximum distance of the reserved gap 411a is 0.05 mm, 0.1 mm, 0.13 mm, 0.15 mm, 0.176 mm, 0.19 mm, 0.2 mm, 0.237 mm, 0.25 mm, 0.265 mm, 0.27 mm, 0.29 mm, 0.3 mm, 0.36 mm, 0.37 mm, 0.4 mm, 0.45 mm, or 0.5 mm. This application embodiment does not limit this.

[0092] It should also be noted that, with the first plane P1 as the dividing line, the reserved gap 411a is formed between the side of the power taking component 311 facing away from the opening of the mounting slot 411 and the inner wall of the mounting slot 411. The distance of the reserved gap 411a is the straight-line distance between the outer side of the power taking component 311 and the inner wall of the mounting slot 411 along the radial direction of the power taking component 311 (or the corresponding lamp tube 31).

[0093] At least two lamps 31 can be connected in series or in parallel, and this application embodiment does not limit this.

[0094] For example, the conductive support may include a first conductive support 41a and a second conductive support 41b, with each lamp tube 31 connected between the first conductive support 41a and the second conductive support 41b. This allows the lamp tubes 31 to form a parallel structure through the first conductive support 41a and the second conductive support 41b.

[0095] It can also be understood that since all the lamps 31 are electrically connected to the circuit board 42 through the first conductive bracket 41a and the second conductive bracket 41b, the consistency of the current transmitted by the circuit board 42 to all the lamps 31 will be higher, thereby making the brightness of the light produced by all the lamps 31 more consistent, which can improve the skin care effect of the skin care device.

[0096] In some embodiments, the conductive support may include a third conductive support and a fourth conductive support, with at least two of the lamps 31 connected in series between the third and fourth conductive supports. Consequently, the consistency of the current transmitted by the circuit board 42 to the series-connected lamps 31 will be higher, resulting in higher consistency of the brightness of the light produced by the series-connected lamps 31, thereby improving the skin care effect of the skin care device.

[0097] In some embodiments, each lamp 31 is connected to the circuit board 42 via a different conductive bracket. Furthermore, if any conductive bracket becomes detached or damaged, the remaining conductive brackets can still supply power to the corresponding lamp 31, ensuring the other lamps 31 of the skin care device can function normally. More importantly, this arrangement can increase the light output power (e.g., hair removal power) and / or the diversity of light output functions (e.g., hair removal function diversity). That is, by providing at least two lamps 31, each mounted and fixed to the circuit board 42 via different conductive brackets, multiple lamps 31 can be turned on simultaneously when increased hair removal power is needed, and only one lamp 31 can be turned on when not needed; alternatively, at least two of the at least two lamps 31 can alternate illumination, thereby increasing the light output power while reducing or eliminating the loss of a single light source.

[0098] It should also be noted here that the conductive component 41 can be a conductive support with conductive function, that is, the conductive support can be a first conductive component made of conductive material, such as copper, aluminum, iron, silver, gold and other materials.

[0099] Optionally, the conductive component may further include a support member and a second conductive member. The support member is used to support and fix the lamp tube, and the second conductive member is used to electrically connect with the lamp tube. For example, the second conductive member may be a conductive wire, but this embodiment of the application does not limit this.

[0100] Please continue to refer to this. Figure 6 In some embodiments, the skin care device further includes a cooling compress component 500 for applying a cooling compress to the skin. This allows the skin care device to simultaneously perform three functions: cooling, skin rejuvenation, and hair removal.

[0101] It is understood that the cooling assembly 500 may be inserted through the light outlet 11 or may be arranged around the light outlet 11, and this application embodiment does not limit this.

[0102] For example, the cooling compress assembly 500 may include a first light-transmitting component 51 and a cooling plate 52. The first light-transmitting component 51 is disposed at the light outlet 11 to transmit light emitted by the lamp tube 31. The cooling plate 52 is thermally connected to the first light-transmitting component 51. Thus, after the first light-transmitting component 51 is cooled by the cooling plate 52, the first light-transmitting component 51 can be used to apply a cold compress to the skin to be treated.

[0103] For example, the cooling chip 52 is directly attached to the first light-transmitting component 51 or is attached to the first light-transmitting component 51 through a thermally conductive medium such as thermally conductive silicone grease, thereby achieving a thermally conductive connection with the first light-transmitting component 51.

[0104] The cooling element 52, also known as the semiconductor cooling element 52, utilizes the Peltier effect of semiconductor materials. When direct current passes through a thermocouple composed of two different semiconductor materials connected in series, heat can be absorbed and released at the two ends of the thermocouple, thus achieving the purpose of cooling.

[0105] The first light-transmitting component 51 can be made of sapphire or other light-guiding materials; this application embodiment does not limit this.

[0106] In some embodiments, the first light-transmitting component 51 includes a light-incident surface 511 facing the lamp tube 31. The angle between the light-incident surface 511 and the first plane P1 is no more than 5°; and / or, the angle between the light-incident surface 511 and the filter 200 is no more than 5°.

[0107] It should be noted that in this application, "and / or" describes the relationship between related objects, indicating that there can be three relationships. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, or B existing alone. Additionally, the character " / ", unless otherwise specified, generally indicates that the related objects before and after it are in an "or" relationship.

[0108] In other words, in this embodiment, the relative angle between the light-incident surface 511 and the first plane P1 may not exceed 5°, while the relative angle between the light-incident surface 511 and the filter 200 may exceed 5°; or the relative angle between the light-incident surface 511 and the first plane P1 may exceed 5°, while the relative angle between the light-incident surface 511 and the filter 200 may not exceed 5°; or the relative angle between the light-incident surface 511 and the first plane P1 may not exceed 5°, and the relative angle between the light-incident surface 511 and the filter 200 may not exceed 5°.

[0109] Furthermore, when the relative angle between the light-incident surface 511 and the first plane P1 does not exceed 5°, it can also be understood that the light-incident surface 511 and the first plane P1 are roughly parallel, thereby making the light generated by the lamp tube 31 at the first plane P1 more uniform in brightness after it is emitted from the first light-transmitting component 51, ultimately improving the skin care effect of the skin care device.

[0110] When the relative angle between the light-incident surface 511 and the filter 200 does not exceed 5°, it can also be understood that the light-incident surface 511 and the first plane P1 are roughly parallel, which makes the light generated by the lamp tube 31 at the first plane P1 more uniform in brightness when it is filtered by the filter 200 and then emitted from the first light-transmitting component 51, ultimately improving the skin care effect of the skin care device.

[0111] It can also be understood that when the relative angle between the light-incident surface 511 and the first plane P1 does not exceed 5°, and the relative angle between the light-incident surface 511 and the filter 200 does not exceed 5°, it can be understood that the light-incident surface 511, the filter 200 and the first plane P1 are roughly parallel to each other, so that the light generated by the lamp tube 31 at the first plane P1 is more uniform in brightness after it is emitted from the first light-transmitting component 51, and ultimately improves the skin care effect of the skin care device.

[0112] For example, the relative deflection angle between the incident light surface 511 and the first plane P1 is 0°, 0.7°, 1°, 1.5°, 2°, 2.7°, 3.1°, 3.5°, 4°, 4.22°, 4.5° or 5°, and this application embodiment does not limit this.

[0113] It is understood that, taking the example where the length or width of the light-incident surface 511 extends vertically, the lower edge of the light-incident surface 511 may be deflected (or tilted) towards the first plane P1, so that there is a relative angle of deflection between the light-incident surface 511 and the first plane P1; the lower edge of the light-incident surface 511 may be deflected (or tilted) away from the first plane P1, so that there is a relative angle of deflection between the light-incident surface 511 and the first plane P1; and the front edge of the light-incident surface 511 may be deflected (or tilted) towards the first plane P1, so that there is a relative angle of deflection between the light-incident surface 511 and the first plane P1; of course, the front edge of the light-incident surface 511 may also be deflected (or tilted) away from the first plane P1, so that there is a relative angle of deflection between the light-incident surface 511 and the first plane P1. This application embodiment does not limit this.

[0114] For example, the relative deflection angle between the light-incident surface 511 and the filter 200 is 0°, 0.7°, 1°, 1.5°, 2°, 2.7°, 3.1°, 3.5°, 4°, 4.22°, 4.5° or 5°, and this embodiment does not limit the specific angle.

[0115] It is understood that, taking the example where the length or width of the light-incident surface 511 extends vertically, the lower edge of the light-incident surface 511 may be deflected (or tilted) towards the filter 200, so that there is a relative angle of deflection between the light-incident surface 511 and the filter 200; the lower edge of the light-incident surface 511 may be deflected (or tilted) away from the filter 200, so that there is a relative angle of deflection between the light-incident surface 511 and the filter 200; and the front edge of the light-incident surface 511 may be deflected (or tilted) towards the filter 200, so that there is a relative angle of deflection between the light-incident surface 511 and the filter 200; of course, the front edge of the light-incident surface 511 may also be deflected (or tilted) away from the filter 200, so that there is a relative angle of deflection between the light-incident surface 511 and the filter 200. This application embodiment does not limit this.

[0116] In some embodiments, on the plane where the light-incident surface 511 is located, the orthographic projection of the lamp tube 31 is located between the two edges of the light-incident surface 511 along the first direction H1, and the first direction H1 is perpendicular to the length direction of the lamp tube 31.

[0117] For example, the first direction H1 can be the vertical direction, that is, in the vertical direction, all the lamps 31 are located between the upper edge and the lower edge of the light-incident surface 511, so that more light generated by the lamps 31 can be directly directed to the light-incident surface 511, thereby improving the light output efficiency of the light-emitting component 300 and thus improving the skin care effect of the skin care device.

[0118] Please continue to refer to this. Figure 7 and Figure 8 In some embodiments, the skin care device further includes a second light-transmitting component 61. The second light-transmitting component 61 is disposed between the first light-transmitting component 51 and the filter 200.

[0119] It is understandable that, on the one hand, the filter 200 generates a large amount of heat when filtering light of a specific wavelength, and on the other hand, because the filter 200 is close to the lamp tube 31, a large amount of heat from the lamp tube 31 is directly transferred to the filter 200. Therefore, in this embodiment, the second light-transmitting component 61 between the first light-transmitting component 51 (or the cooling component 500) and the filter 200 can prevent direct contact between the filter 200 and the first light-transmitting component 51 (or the cooling component 500), thereby reducing the heat transferred from the filter 200 to the first light-transmitting component 51 (or the cooling component 500), and thus ensuring the cooling effect of the first light-transmitting component 51.

[0120] In some embodiments, the skin care device further includes a seal 62, which is at least partially disposed between the second light-transmitting component 61 and the first light-transmitting component 51 to form a first sealed space 621 between the second light-transmitting component 61 and the first light-transmitting component 51. The seal 62 is also at least partially disposed between the second light-transmitting component 61 and the filter 200 to form a second sealed space 622 between the second light-transmitting component 61 and the filter 200.

[0121] Furthermore, compared to the direct contact between the second light-transmitting component 61 and the first light-transmitting component 51, the air gap in the first sealed space 621 can reduce the heat exchange efficiency between the second light-transmitting component 61 and the first light-transmitting component 51, thereby reducing the heat transferred from the second light-transmitting component 61 to the first light-transmitting component 51, thus improving the cooling effect of the cooling assembly 500; and the air gap in the first sealed space 621 can also increase the length of the heat exchange path between the light-emitting component 300 and the first light-transmitting component 51, thereby reducing the heat transferred from the light-emitting component 300 to the first light-transmitting component 51, thus improving the cooling effect of the cooling assembly 500. In addition, it can also improve the problem of water vapor easily caused by the large temperature difference on both sides of the second light-transmitting component 61.

[0122] Similarly, compared to the direct contact between the second light-transmitting component 61 and the filter 200, the air gap in the second sealed space 622 can reduce the heat exchange efficiency between the second light-transmitting component 61 and the filter 200, thereby reducing the heat transferred from the second light-transmitting component 61 to the first light-transmitting component 51, thus improving the cooling effect of the cooling assembly 500; and the air gap in the second sealed space 622 can also increase the length of the heat exchange path between the light-emitting component 300 and the first light-transmitting component 51, thereby reducing the heat transferred from the light-emitting component 300 to the first light-transmitting component 51, thus improving the cooling effect of the cooling assembly 500. In addition, it can also improve the problem of water vapor easily caused by excessive temperature difference on both sides of the filter 200.

[0123] For example, the sealing member 62 can be a sealing ring, which is sandwiched between the first light-transmitting member 51 and the filter 200. The inner circumferential side of the sealing member 62 is provided with a mounting groove, and the peripheral edge of the second light-transmitting member 61 is installed in the mounting groove, so that the sealing member 62 is partially disposed between the filter 200 and the first light-transmitting member 51 to form a first sealing space 621 between the filter 200 and the first light-transmitting member 51, and the sealing member 62 is also partially disposed between the filter 200 and the second light-transmitting member 61 to form a second sealing space 622 between the filter 200 and the second light-transmitting member 61.

[0124] In some embodiments, the skin care device also includes a heat dissipation assembly 700, which is disposed within the housing 100 for dissipating heat from the cooling assembly 500 and / or the light-emitting assembly 300.

[0125] For example, the housing 100 has a first heat dissipation channel 81, and the light-emitting component 300 is at least partially disposed within the first heat dissipation channel 81. The heat dissipation component 700 includes a fan 71, which drives the gas in the first heat dissipation channel 81 to convect with the gas outside the housing 100 to dissipate heat from the light-emitting component 300.

[0126] like Figure 5 As shown, in some embodiments, the light-emitting assembly 300 further includes a reflector 32, which is at least partially located on the side of the lamp tube 31 away from the light outlet 11, so as to reflect part of the light generated by the lamp tube 31 to the light outlet 11. In this way, the light emission efficiency of the light-emitting assembly 300 can be improved by the reflector 32, and the skin care effect of the skin care device can be improved.

[0127] The reflector 32 has a first heat sink 33 on the side of its surface facing away from the lamp tube 31, which can improve the heat dissipation effect of the reflector 32.

[0128] For example, the reflective component 32 may have a first heat sink 33 on the side facing the fan 71, thereby increasing the contact area between the air blown by the fan 71 toward the light-emitting component 300 and the first heat sink 33, thus improving heat dissipation efficiency.

[0129] In some embodiments, a second heat dissipation channel 82 is provided within the housing 100. The heat dissipation assembly 700 includes a heat spreader 72, a second heat sink 73, and a fan 71. The heat spreader 72 is thermally connected to the cooling chip 52, the second heat sink 73 is disposed on the heat spreader 72 and is at least partially located within the second heat dissipation channel 82, and the fan 71 is also used to drive the gas within the second heat dissipation channel 82 to convect with the gas outside the housing 100 to dissipate heat from the cooling assembly 500.

[0130] In some embodiments, the first heat dissipation channel 81 and the second heat dissipation channel 82 are formed on different sides of the heat spreader 72. One end of the heat spreader 72 is thermally connected to the cooling assembly 500. The other end of the heat spreader 72 is located at the air outlet of the fan 71, so that the end of the heat spreader 72 near the fan 71 can divert the air flowing out of the fan 71 to the first heat dissipation channel 81 and the second heat dissipation channel 82.

[0131] Since the air flowing out of the fan 71 flows through different sides of the heat exchange plate 72, the contact area between the heat exchange plate 72 and the cooling airflow is increased, thereby improving the heat dissipation efficiency of the heat exchange plate 72, which in turn improves the heat dissipation effect of the cooling assembly 500, and ultimately improves the overall heat dissipation effect of the skin care equipment.

[0132] It should be noted that one end of the heat spreader 72 is thermally connected to the cooling assembly 500. This connection can be achieved by directly attaching one end of the heat spreader 72 to the cooling assembly 500 or by attaching it to the cooling assembly 500 via a thermally conductive medium such as thermal grease. This allows heat from the cooling assembly 500 to be evenly transferred to all parts of the heat spreader 72. The second heat sink 73 then increases the contact area with air, thereby improving the heat dissipation efficiency of the cooling assembly 500. The second heat sink 73 can be a heat sink.

[0133] In some embodiments, the skin care device further includes a support assembly 800. The support assembly 800 is disposed within the housing 100, and the support assembly 800 or the housing 100 forms a first heat dissipation channel 81 and a second heat dissipation channel 82.

[0134] Therefore, compared to directly manufacturing the housing 100 with the first heat dissipation channel 81 and the second heat dissipation channel 82, in this embodiment of the application, the method of forming the first heat dissipation channel 81 and the second heat dissipation channel 82 by the bracket assembly 800 in conjunction with the housing 100 can reduce the manufacturing difficulty of the first heat dissipation channel 81 and the second heat dissipation channel 82.

[0135] Secondly, embodiments of this application also provide a skin care device, which may include a housing 100, a filter 200, a light-emitting component 300, and a conductive component 41.

[0136] The housing 100 is provided with a light outlet 11. A filter 200 is disposed near the light outlet 11 and allows light of a preset wavelength to pass through. A light-emitting assembly 300 is disposed within the housing 100. The light-emitting assembly 300 includes at least two lamps 31, which define a first plane P1. The angle between the filter 200 and the first plane P1 does not exceed 30°. The closest distance between two adjacent lamps 31 is not less than 1 mm. A conductive component 41 is connected to the lamps 31 and is used to position the lamps 31 to define the first plane P1. The conductive component 41 can provide an operating voltage to the lamps 31 to generate light and direct it toward the filter 200. The light generated by the lamps 31 and filtered by the filter 200 can be directed from the light outlet 11 toward the skin to be treated.

[0137] Therefore, in this embodiment, on the one hand, since the angle between the first plane P1 determined by at least two lamps 31 and the filter 200 is controlled to be no more than 30°, the brightness of the light generated by the lamps 31 at the first plane P1 after being filtered by the filter 200 is more uniform; on the other hand, the closest distance D1 between two adjacent lamps 31 is not less than 1 mm, thereby avoiding the large amount of heat generated by the lamps 31 when they are working from interfering with the adjacent lamps 31 by avoiding the distance between two adjacent lamps 31 being too close, and ultimately improving the skin care effect of the skin care device in this embodiment.

[0138] In some embodiments, the specific structures of the housing 100, the filter 200, the light-emitting component 300 and the conductive component 41 can be referred to the housing 100, the filter 200, the light-emitting component 300 and the conductive component 41 described in the first aspect, and will not be repeated here in the embodiments of this application.

[0139] In some embodiments, the skin care device may further include a circuit board assembly 400, a cooling assembly 500, a second light-transmitting component 61, a sealing component 62, a heat dissipation assembly 700, and a support assembly 800, etc. The specific structures of the circuit board assembly 400, the cooling assembly 500, the second light-transmitting component 61, the sealing component 62, the heat dissipation assembly 700, and the support assembly 800 can be referred to in the first aspect for their specific structures, which will not be repeated in the embodiments of this application.
