[0048] Hereinafter, technical solutions according to the embodiments of the present application will be clearly and completely explained in conjunction with the attached drawings according to the embodiments of the present application. It is obvious that the described embodiments are merely some embodiments of the present application and not all embodiments. All other embodiments that can be obtained by a person skilled in the art without requiring creative labor based on the embodiments in the present application fall within the scope of protection of the present application.

[0049] Referring to FIGS. 1 and 2, FIG. 1 is a schematic diagram of one structure of a skin treatment device provided in an embodiment of the present application, and FIG. 2 is a cross-sectional view along the AA direction of the skin treatment device shown in FIG. 1. An embodiment of the present application provides a skin treatment device.

[0050] Skin treatment devices are devices that regulate and improve the condition of the body and facial skin according to the physiological functions of the human body, and depending on their function, they offer features such as whitening, skin regeneration, blemish removal, wrinkle improvement, and hair removal. Among these, various effects can be achieved by irradiating the skin with light in specific frequency bands or other types based on optics. For example, strong pulsed light, LED light, and lasers have traditionally been the most widely applied.

[0051] For example, a skin treatment device is a hair removal device or a skin regenerator.

[0052] The skin treatment device may include a housing (100), a light-emitting assembly (200), a cold compress assembly (300), and a heat dissipation assembly (400).

[0053] A light-emitting area (11) is provided in the housing (100). A light-emitting assembly (200) is installed within the housing (100), and the light-emitting assembly (200) is used to generate light rays that are irradiated from the light-emitting area (11) onto the skin awaiting treatment. A cold compress assembly (300) is installed at the location of the light-emitting area (11) and is used to apply a cold compress to the skin. A heat dissipation assembly (400) is used to dissipate heat to the light-emitting assembly (200) and / or the cold compress assembly (300).

[0054] Depending on the type of light ray generated from the light-emitting assembly (200), the skin treatment device can be divided into various types. For example, the light-emitting assembly (200) may be used to generate a laser, which is a laser light source assembly, and the skin treatment device is a laser-type skin treatment device; for example, the light-emitting assembly (200) may be used to generate IPL light (intense pulsed light), which is an IPL light source assembly (e.g., a xenon lamp assembly), and the skin treatment device is an intense pulsed light-type skin treatment device; for example, the light-emitting assembly (200) is an LED light source assembly.

[0055] The present application will be described below with an example in which the light-emitting assembly (200) is primarily an IPL light source assembly. The light-emitting principle of such a skin treatment device is as described below. A capacitor is connected to a power source and is charged by stepping up the voltage with a transformer assembly. When the capacitor is charged and reaches a preset value, and after the controller receives a triggering signal, the electrical energy within the capacitor is released, and the instantaneous voltage can reach several hundred volts, and furthermore, the lamp tube is excited to instantaneously emit strong pulse light, thereby completing one light-emitting cycle.

[0056] In some embodiments, the light-emitting area (11) may be an opening structure, such as a light-emitting port or light-emitting hole, provided in the housing (100).

[0057] Optionally, the light-emitting area (11) may be formed as a partial light-transmitting area on the housing (100). For example, at least a portion of the housing (100) of a skin treatment device, such as a head case, may be made of a light-transmitting material, and a light-blocking layer may be installed in a local area of ​​the head case to form a light-emitting area (11) at a location in the head case where the light-blocking layer is not installed. The embodiments of the present application are not limited thereto.

[0058] The heat dissipation assembly (400) includes a fan (41). A first air outlet (413) is provided in the fan (41), and the first air outlet (413) is provided on one side where the light emission assembly (200) is positioned away from the light emission area (11).

[0059] A classification structure (42a) may be further installed within the housing (100), and the classification structure (42a) may be installed at the location of the first air outlet (413), so that a first partial wind may flow through one side of the classification structure (42a) through a fan (41) to dissipate heat to the light-emitting assembly (200), and a second partial wind may flow through the other side of the classification structure (42a) through a fan (41) to dissipate heat to the cold compress assembly (300).

[0060] For example, in an embodiment of the present application, the first air outlet (413) may be an air outlet, thereby classifying the wind blown from the fan (41) through the classification structure (42a) to form a first partial wind and a second partial wind, thereby dissipating heat to the light-emitting assembly (200) and the cold compress assembly (300), respectively, and further enabling effective heat dissipation to the light-emitting assembly (200) and the cold compress assembly (300), thereby improving the heat dissipation effect of the entire skin treatment device. Of course, the first air outlet (413) may be an air inlet of the fan (41), and the embodiment of the present application is not limited thereto.

[0061] The fan (41) may be a centrifugal fan, a cross-flow fan, etc., and the embodiments of the present application are not limited thereto.

[0062] For example, if the fan (41) is a centrifugal fan, the first air outlet (413) may be an outlet or inlet of a volute casing, and the first air outlet (413) may be an outlet of a duct assembly mounted at the outlet or inlet location of the volute casing, etc., and the embodiments of the present application are not limited thereto.

[0063] If the fan (41) is a centrifugal fan, the width direction of the first air outlet (413) may be the thickness direction of the volute casing.

[0064] In some embodiments, a third air outlet (414) is further provided in the fan (41). One of the first air outlet (413) and the third air outlet (414) is an inlet of the fan (41), and the other of the first air outlet (413) and the third air outlet (414) is an outlet of the fan (41). Correspondingly, a fourth air outlet (12) is further provided in the housing (100), and the fourth air outlet (12) is connected to the outside of the housing (100) and the third air outlet (414), respectively.

[0065] When the first air outlet (413) is an air outlet, the fan (41) first sucks in wind from outside the housing (100) through the third air outlet (414) and the fourth air outlet (12), and then the fan (41) discharges the sucked wind from the first air outlet (413) and classifies it through the classification structure (42a), thereby realizing heat dissipation of the cold compress assembly (300) and the light-emitting assembly (200).

[0066] For example, the fourth air outlet (12) may include the first housing air outlet (121), and the first housing air outlet (121) is provided to correspond to (e.g., to face) the air outlet of the fan (41).

[0067] The fourth air outlet (12) may further include a second housing air outlet (122), and the second housing air outlet (122) is provided at one end facing away from the light emission area (11) in the housing (100).

[0068] The above description is an overall example of a technical solution according to an embodiment of the present application. Below, a technical solution according to an embodiment of the present application will be described by example in conjunction with a selectable structure of a classification structure (42a).

[0069] It can be understood that the classification structure (42a) may be part of the heat dissipation assembly (400) and may be part of other parts of the skin treatment device, and the embodiments of the present application are not limited thereto.

[0070] For example, continuing with reference to FIGS. 3 and 4, FIG. 3 is a schematic diagram of the mounting positions of the light-emitting assembly, cold compress assembly, and heat dissipation assembly of the skin treatment device illustrated in FIG. 2, and FIG. 4 is a local enlarged view of position X in FIG. 2. The heat dissipation assembly (400) may further include a temperature-balancing plate (42) and heat dissipation fins (43) mounted on the temperature-balancing plate (42). One end of the temperature-balancing plate (42) is heat-conducted connected to the cold compress assembly (300); For example, one end of the temperature plate (42) is directly bonded to the cold compress assembly (300) or bonded to the cold compress assembly (300) through a heat-conducting medium such as thermally conductive silicone grease, and furthermore, the heat amount at the location of the cold compress assembly (300) can be uniformly transferred to each location of the temperature plate (42), and then the contact area with air is expanded through the heat dissipation fins (43) to improve the heat dissipation efficiency for the cold compress assembly (300). The other end of the temperature plate (42) is located at the location of the first air outlet (413) to form at least a portion of the classification structure (42a). Alternatively, it may be understood that the other end of the temperature plate (42) is positioned at the location of the first air outlet (413), and that the first partial wind is driven through the fan (41) so that the temperature plate (42) flows past the side facing the heat dissipation fin (43) and the light-emitting assembly (200), thereby being used to dissipate heat to the light-emitting assembly (200), and that the second partial wind is driven through the fan (41) so that it flows past the heat dissipation fin (43), thereby being used to dissipate heat to the cold compress assembly (300).

[0071] By driving the first partial wind and the second partial wind to flow through the upper side of the temperature plate (42) respectively through the fan (41), the contact area between the temperature plate (42) and the cooling airflow is expanded, thereby improving the heat dissipation efficiency for the temperature plate (42), further improving the heat dissipation effect for the cold compress assembly (300), and finally improving the heat dissipation effect of the entire skin treatment device.

[0072] It is further understandable that the ion plate (42) forms at least some of the classification structure (42a), which means that the classification structure (42a) may not only be formed solely by the ion plate (42), but may also be composed of the ion plate (42) and its components, and the embodiments of the present application are not limited thereto.

[0073] Below, we will first provide an overall explanation of the structure of the cold compress assembly (300) and then explain the heat dissipation principle of the temperature plate (42) for the cold compress assembly (300).

[0074] In some embodiments, the cold compress assembly (300) is installed at the location of the light-emitting area (11), so that the cold compress assembly (300) can penetrate the light-emitting area (11), or the cold compress assembly (300) may be installed at the orifice cross-section of the light-emitting area (11).

[0075] For example, the cold compress assembly (300) may include a first light guide member (31) and a cooling sheet (32). The first light guide member (31) is installed in the light-emitting area (11) and transmits a light beam emitted from the light-emitting assembly (200). The cooling sheet (32) is heat-conducted to the first light guide member (31). For example, the cooling sheet (32) is directly bonded to the first light guide member (31) or is bonded to the first light guide member (31) through a heat-conducting medium such as heat-conducting silicone grease.

[0076] Furthermore, the first light guide member (31) can be cooled through the cooling sheet (32), and the first light guide member (31) after cooling can be exposed from the position of the light emission area (11) and come into contact with the skin, so that the first light guide member (31) can transmit light from the light source (22) to provide care to the user's skin, and also provide a cold compress to the user by cooling through the cooling sheet (32).

[0077] Specifically, the cooling sheet (32) is also called a semiconductor cooling sheet, and by utilizing the Peltier effect of the semiconductor material, when a direct current passes through an electric pair connected in series with two different semiconductor materials, the two ends of the electric pair each carry out heat absorption and heat release, thereby realizing the purpose of cooling.

[0078] The first light guide member (31) may be made of sapphire material or other light guide material, and the embodiments of the present application are not limited thereto.

[0079] Optionally, the cold compress assembly (300) may further include a cold compress member (not shown) and a cooling sheet (32). The cold compress member is installed on one side / periphery of the light-emitting area (11). The cooling sheet (32) is heat-conducted to the cold compress member. For example, the cooling sheet (32) is directly bonded to the cold compress member or bonded to the cold compress member through a heat-conducting medium such as heat-conductive silicone grease. Furthermore, the cold compress member can be cooled through the cooling sheet (32), and the cold compress member, after cooling, can be exposed from one side / periphery of the light-emitting area (11) and come into contact with the skin, thereby providing a cold compress to the user.

[0080] For example, the cold compress member may be a ring-shaped metal member installed around the light-emitting area (11).

[0081] The heat conduction connection between the temperature plate (42) and the cold compress assembly (300) may be a heat conduction connection between the temperature plate (42) and the cooling sheet (32). For example, the temperature plate (42) may be directly bonded to the cooling sheet (32) or bonded to the cooling sheet (32) through a heat conduction medium such as thermally conductive silicone grease. In this way, the amount of heat at the location of the cooling sheet (32) can be uniformly and quickly transferred to each location on the temperature plate (42), and then, the temperature plate (42) expands the contact area with air through the heat dissipation fins (43), thereby realizing rapid heat dissipation.

[0082] In addition, in conjunction with an example where the temperature plate (42) forms at least a portion of the classification structure (42a), the skin treatment device may further include a bracket assembly (500). The bracket assembly (500) is installed inside the housing (100). The bracket assembly (500) and the temperature plate (42) form a first heat dissipation duct (51) and a second heat dissipation duct (52). Here, at least a portion of the light-emitting assembly (200) is mounted within the first heat dissipation duct (51) to allow a first portion of air to flow into the first heat dissipation duct (51) and to dissipate heat to the light-emitting assembly (200). Here, the heat dissipation fin (43) is installed within the second heat dissipation duct (52) to allow a second portion of air to flow into the second heat dissipation duct (52) and to dissipate heat to the cold compress assembly (300). Furthermore, heat dissipation can be performed on each of the light-emitting assembly (200) and the cold compress assembly (300) so that the heat dissipation effect of both the light-emitting assembly (200) and the cold compress assembly (300) is secured.

[0083] For example, one side of the thermal plate (42), for example, the side facing the heat dissipation fin (43), and the bracket assembly (500) form a blower access segment of the first heat dissipation duct (51), and the blower access segment of the first heat dissipation duct (51) is connected to the first blower (413), so that a first partial wind can be used to flow through the first heat dissipation duct (51) through the fan (41) and / or driven to dissipate heat to the light-emitting assembly (200). The other side of the temperature plate (42), for example, the side approaching the heat dissipation fin (43), and the bracket assembly (500) form a blower access segment of the second heat dissipation duct (52), and the blower access segment of the second heat dissipation duct (52) is connected to the first blower (413), so that the second partial wind can be driven through the second heat dissipation duct (52) via the fan (41) to dissipate heat to the cold compress assembly (300). Furthermore, by using both sides of the temperature plate to form the blower access segment of the first heat dissipation duct (51) and the blower access segment of the second heat dissipation duct (52), respectively, the first partial wind can dissipate heat to the light emission assembly (200), and at the same time, additional heat can be dissipated to the temperature plate (42), so that it is used redundantly for heat dissipation to the cold compress assembly (300).

[0084] In some embodiments, the bracket assembly (500) may be provided with corresponding slots and ribs inside and may be used to mount a light-emitting assembly (200), a cold compress assembly (300), and at least some heat dissipation assembly (400).

[0085] In some embodiments, a light-emitting part (53) may be installed on the inner wall of the first heat dissipation duct (51). The light-emitting part (53) is located between the light-emitting assembly (200) and the light-emitting area (11) of the housing (100). The light-emitting part (53) is used to transmit light rays generated from the light-emitting assembly (200) to the light-emitting area (11).

[0086] For example, the light-emitting part (53) may be a through hole, and the first light guide member (31) of the cold compress assembly (300), for example, the cold compress assembly (300), penetrates the light-emitting part (53) to close the light-emitting part (53).

[0087] Alternatively, the light-emitting part (53) may be a second light guide member. The second light guide member is installed on one side where the inner wall of the first heat dissipation duct (51) faces the light-emitting area (11).

[0088] The second light guide member may be a single insulated light-transmitting member, thereby preventing the heat generated from the light-emitting assembly (200) from being directly transferred to the location of the cold compress assembly (300). Of course, the second light guide member may not be an insulated light-transmitting member, and the embodiments of the present application are not limited thereto.

[0089] Alternatively, the second light guide member is an optical filter.

[0090] The bracket assembly (500) may further include an optical filter member (54). The optical filter member (54) may include an optical filter. The optical filter member (54) is used to transmit light rays with a wavelength between 560 nm and 1200 nm, thereby forming an IPL (intense pulsed light) ray within a specific wavelength range and irradiating it onto the user's skin. In actual use, the wavelength of the light required for hair removal may be between 560 nm and 1200 nm, and the wavelength of the light required for skin regeneration may be between 640 nm and 1200 nm. This allows the skin care device to simultaneously provide two functions: cold compress and skin regeneration or hair removal. Of course, other functions may also be realized through the installation of the light emitting assembly (200), or the light emitting assembly (200) and the optical filter.

[0091] In some embodiments, the type of optical filter is adjusted, and the second light guide member, the optical filter member (54), and the first light guide member (31) can be installed sequentially along a direction away from the light-emitting assembly (200). This allows the skin care device to simultaneously provide three functions: cold compress, skin regeneration, and hair removal.

[0092] In some embodiments, the skin treatment device further includes a bracket assembly (500). The bracket assembly (500) is installed within the housing (100), and the bracket assembly (500) and the temperature plate (42) form a first heat dissipation duct (51) to allow a first partial airflow to pass through. Here, at least a portion of the light-emitting assembly (200) is installed within the first heat dissipation duct (51) to allow the first partial airflow to pass through the light-emitting assembly (200), thereby dissipating heat to the light-emitting assembly (200). The bracket assembly (500) may further include an isolation portion (55). The isolation portion (55) isolates the light-emitting assembly (200) and the temperature plate (42).

[0093] It is understandable that the thermal plate (42) may include a copper alloy thermal plate, a VC (Vapor Chamber, vacuum chamber thermal dissipation technology) thermal plate, a stainless steel thermal plate, a graphene thermal plate, etc., and the embodiments of the present application are not limited thereto. The thermal plate (42) generally has electrical conductivity. Not only can the distance between the thermal plate (42) and the light-emitting assembly (200) be reduced through the isolation part (55), but furthermore, the skin treatment device can be made lighter and slimmer overall, and leakage current can be avoided by preventing the distance between the light-emitting assembly (200) and the thermal plate (42) from being too close, thereby improving the reliability and safety of the skin treatment device.

[0094] The isolation portion (55) may be an insulating material such as plastic, rubber, ceramic, or even an insulating layer, and the embodiments of the present application are not limited thereto.

[0095] In some embodiments, when the light-emitting assembly (200) is directed toward the first air outlet (413), the isolation portion (55) is shorter than the temperature plate (42) and is supported by the temperature plate (42). Furthermore, since the isolation portion (55) is shorter, on the one hand, the manufacturing difficulty of the bracket assembly (500) is reduced, the manufacturing cost of the bracket assembly (500) is reduced, and the overall weight of the skin treatment device can be reduced; on the other hand, more positions of the temperature plate (42) can be exposed, thereby expanding the contact area between the temperature plate (42) and the first partial wind, further improving the heat dissipation efficiency of the temperature plate (42), and finally improving the heat dissipation effect of the cold compress assembly (300).

[0096] In some embodiments, one surface facing the light-emitting assembly (200) from the temperature plate (42) includes a blocking area (422) and an exposed area (423). The isolation portion (55) is supported by the blocking area (422). Here, the minimum distance between the exposed area (423) and the light-emitting assembly (200) is 6 mm or more, thereby preventing short circuits caused by the distance between the temperature plate (42) and the light-emitting assembly (200) being too close.

[0097] For example, the minimum distance between the exposure area (423) and the light-emitting assembly (200) may be 6 mm, 6.1 mm, 6.7 mm, 7.4 mm, 8 mm, or 9 mm, etc., and the embodiments of the present application are not limited thereto.

[0098] In some embodiments, one surface of the uniform plate (42) facing the light-emitting assembly (200) includes a blocking area (422) and an exposed area (423). The isolation portion (55) is supported by the blocking area (422). Here, the exposed area (423) is a flat area and is used for guiding and heat dissipation. It is understandable that since the exposed area (423) also forms the inner wall of the first heat dissipation duct (51), the exposed area (423) is a flat area compared to the exposed area (423) being uneven, and thus can effectively reduce wind resistance when the first portion of wind flows within the first heat dissipation duct (51).

[0099] Specifically, the minimum distance between the exposure area (423) and the light-emitting assembly (200) may be 6 mm or more, and the exposure area (423) may be a flat area, the minimum distance between the exposure area (423) and the light-emitting assembly (200) may be less than 6 mm, and the exposure area (423) may be a flat area, the minimum distance between the exposure area (423) and the light-emitting assembly (200) may be less than 6 mm, and an uneven structure may be provided on the surface of the exposure area (423), and the embodiments of the present application are not limited thereto.

[0100] Below, we will continue to describe, for example, that at least a part of the classification structure (42a) is formed as part of other parts of the skin treatment device.

[0101] For example, continuing with reference to FIG. 5, FIG. 5 is a schematic diagram of another classification structure at position X in FIG. 2. The skin treatment device further includes a bracket assembly (500). The bracket assembly (500) is installed inside the housing (100). The bracket assembly (500) is used to form a first heat dissipation duct (51) and a second heat dissipation duct (52). The first heat dissipation duct (51) is used to dissipate heat to the light-emitting assembly (200) by allowing a first partial airflow, and the second heat dissipation duct (52) is used to dissipate heat to the cold compress assembly (300) by allowing a second partial airflow. Here, a classification section (56) is installed at one end of the bracket assembly (500) that approaches the first air outlet (413) to form a classification structure (42a), thereby blocking the air outlet through which the first heat dissipation duct (51) communicates with the fan (41) and the air outlet through which the second heat dissipation duct (52) communicates with the fan (41). Finally, heat dissipation is carried out for the light-emitting assembly (200) and the cold compress assembly (300), respectively, so that the heat dissipation effect of both the light-emitting assembly (200) and the cold compress assembly (300) can be secured.

[0102] For example, at least a portion of the light-emitting assembly (200) is installed within the first heat dissipation duct (51). Thus, after the first portion of the wind is introduced into the first heat dissipation duct (51), heat dissipation can be performed on the light-emitting assembly (200).

[0103] The heat dissipation assembly (400) may further include a temperature plate (42) and a heat dissipation fin (43) mounted on the temperature plate (42). One end of the temperature plate (42) is heat-conducted connected to the cold compress assembly (300). At least a portion of both the temperature plate (42) and the heat dissipation fin (43) are installed within the second heat dissipation duct (52); thereby, after the second portion of the wind flows into the second heat dissipation duct (52), heat dissipation can proceed with the temperature plate (42) and the heat dissipation fin (43), and finally, heat dissipation is realized for the cold compress assembly (300).

[0104] In some embodiments, the light-emitting assembly (200) is installed extending along the longitudinal direction of the first air outlet (413). Then, for example, if the first air outlet (413) is the outlet of the fan (41), the first partial wind flowing out from the location of the first air outlet (413) can be blown directly to more locations along the longitudinal direction of the light-emitting assembly (200), thereby improving the heat dissipation effect and making the internal structure of the skin treatment device simpler and more compact.

[0105] In some embodiments, the first partial wind and the second partial wind may flow out from the first air outlet (413) along different regions in the width direction. Alternatively, the air outlet access segment of the first heat dissipation duct (51) (if the first air outlet (413) is an outlet, the air outlet access segment of the first heat dissipation duct (51) is its inlet segment) and the air outlet access segment of the second heat dissipation duct (52) (if the first air outlet (413) is an outlet, the air outlet access segment of the second heat dissipation duct (52) is its inlet segment) are each connected to different regions in the width direction of the first air outlet (413).

[0106] For example, the length of the light-emitting assembly (200) can be extended along the left-right direction, and the length direction of the first air outlet (413) can also be extended along the left-right direction. The inlet of the first heat dissipation duct (51) is connected to the lower half of the first air outlet (413), and the inlet of the second heat dissipation duct (52) is connected to the upper half of the first air outlet (413).

[0107] Continuing with reference to FIG. 6, FIG. 6 is another cross-sectional view along the AA direction of the skin treatment device of FIG. 1. The first heat dissipation duct (51) includes a mounting segment (511) and a flow guide segment (512) arranged along the direction in which the light-emitting assembly (200) faces the first air outlet (413). At least a portion of the light-emitting assembly (200) is mounted on the mounting segment (511). One end of the flow guide segment (512) is located at the position of the first air outlet (413) and is connected to the first air outlet (413), and the other end is connected to the mounting segment (511). Thus, communication between the first heat dissipation duct (51) and the fan (41) is realized, and, for example, the first portion of wind flowing out from the position of the first air outlet (413) can flow directly to the mounting segment (511) through the flow guide segment (512) and proceed with heat dissipation for the light-emitting assembly (200).

[0108] It can be understood that the air outlet access segment of the first heat dissipation duct (51) is formed in the flow guide segment (512).

[0109] It should be noted here that at least a portion of the light-emitting assembly (200) is mounted on the mounting segment (511), so that the light-emitting assembly (200) can be installed entirely within the mounting segment (511). At least a portion of the light-emitting assembly (200) is mounted on the mounting segment (511), so that only a portion of the light-emitting assembly (200) is installed within the mounting segment (511). For example, the light-emitting assembly (200) may be installed partially outside the mounting segment (511) by penetrating both ends of the light-emitting assembly (200) into the inner wall of the mounting segment (511); or the light-emitting assembly (200) may be partially protruded within the guide segment (512), and embodiments of the present application are not limited thereto.

[0110] In some embodiments, the cross-sectional area of ​​at least a portion of the flow segment (512) is gradually expanded along the direction in which the first blower (413) faces the light-emitting assembly (200).

[0111] Then, the flow guide segment (512) can form a pressure expansion structure. When a portion of the wind from the first air outlet (413) flows into the flow guide segment (512), the cross-sectional area of ​​the partial region within the flow guide segment (512) gradually expands along the direction of wind flow. Therefore, compared to the cross-sectional area within the flow guide segment (512) not changing or gradually shrinking along the direction of wind flow, the wind resistance is smaller when the gas flows within the flow guide segment (512), thereby allowing more wind flowing out from the first air outlet (413) to flow smoothly into the flow guide segment (512) and further improving the heat dissipation effect for the light-emitting assembly (200).

[0112] In some embodiments, the width of the flow guide segment (512) in the width direction of the first air outlet (413) is gradually expanded. Furthermore, on one hand, the cross-sectional area of ​​the flow guide segment (512) is gradually expanded according to the direction of wind flow, which is advantageous, and on the other hand, the contact area between the first partial wind and the light-emitting assembly (200) can be expanded. Furthermore, the first partial wind can improve the heat dissipation effect on the light-emitting assembly (200).

[0113] In some embodiments, the inner wall of the flow segment (512) includes a first inner wall (513) facing the classification structure (42a) and a second inner wall (514) facing the first inner wall (513). Along the direction in which the first air outlet (413) faces the light-emitting assembly (200), at least one of the first inner wall (513) and the second inner wall (514) is installed at an angle toward the other so that the gap between the first inner wall (513) and the second inner wall (514) is gradually widened.

[0114] Specifically, the first inner wall (513) and the second inner wall (514) may both be installed at an angle toward each other, and one of the first inner wall (513) and the second inner wall (514) may be installed at an angle toward the other, and the embodiments of the present application are not limited thereto.

[0115] It is further understandable that the second inner wall (514) may be formed from the classification structure (42a) described above, for example, the classification plate (42) and / or the classification part (56) of the bracket assembly (500), and the second inner wall (514) may be formed from the classification structure (42a) and other parts, and the embodiments of the present application are not limited thereto.

[0116] In some embodiments, the width of the section approaching the light-emitting assembly (200) from the flow segment (512) in the direction in which the first inner wall (513) faces the second inner wall (514) is greater than the width of the light-emitting assembly (200). By doing so, the first partial wind flowing out from the fan (41) can be blown directly onto the one side surface facing the first air outlet (413) from the light-emitting assembly (200), thereby expanding the heat dissipation area and improving the heat dissipation effect on the light-emitting assembly (200).

[0117] In conjunction with FIGS. 6 and 7, FIG. 7 is a local enlarged view of the Y position in FIG. 6. A first turbulence prevention structure (515) is installed within the flow guide segment (512) and is used to limit the formation of turbulence within the flow guide segment (512). In this way, the first partial wind can flow more smoothly from the flow guide segment (512) into the mounting segment (511) to proceed with heat dissipation, or the flow velocity of the first partial wind within the flow guide segment (512) can be increased, thereby improving the heat dissipation effect.

[0118] For example, the light-emitting assembly (200) includes a reflective member (21) and a light source (22) installed within the reflective member (21).

[0119] The outer wall of the reflective member (21) includes a first curved surface protruding toward the direction of the flow guide segment (512). The first anti-turbulence structure (515) is used to limit turbulence formed between the first curved surface and the inner wall of the flow guide segment (512).

[0120] Specifically, the first partial wind blows toward the light-emitting assembly (200) and is blocked by the first curved surface, causing it to partially return into the flow guide segment (512). At this time, the first turbulence prevention structure (515) can prevent the airflow within the flow guide segment (512) that is blocked by the first curved surface and returns, as well as the airflow entering the flow guide segment (512) from the fan (41), from forming turbulence, thereby allowing the first partial wind to flow more smoothly within the first heat dissipation duct (51), thereby improving the flow velocity and heat dissipation effect of the first partial wind.

[0121] In one embodiment, the light source (22) may include a light tube. The reflective member (21) includes an arch portion (211) installed to surround the light tube. At least a portion of the arch portion (211) is located on one side where the light tube approaches the flow guide segment (512). Here, one end of the arch portion (211) in the circumferential direction is adjacent to the first inner wall (513), and the other end of the arch portion (211) in the circumferential direction is adjacent to the second inner wall (514). A first turbulence prevention structure (515) is installed on the first inner wall (513) and / or the second inner wall (514).

[0122] Thus, the first turbulence prevention structure (515) can limit the formation of turbulence by preventing wind returning from the outer surface of the arch portion (211) to the first inner wall (513) and / or the second inner wall (514).

[0123] Specifically, the first turbulence prevention structure (515) may be installed only on the first inner wall (513), the first turbulence prevention structure (515) may be installed only on the second inner wall (514), and the first turbulence prevention structure (515) may be installed on both the first inner wall (513) and the second inner wall (514), and the embodiments of the present application are not limited thereto.

[0124] In some embodiments, the first turbulence prevention structure (515) may be formed integrally with the corresponding first inner wall (513) or second inner wall (514). Of course, the first turbulence prevention structure (515) may be formed separately from the corresponding first inner wall (513) or second inner wall (514), and, for example, the first turbulence prevention structure (515) may be detachably connected to the first inner wall (513) or second inner wall (514). The embodiments of the present application are not limited thereto.

[0125] In some embodiments, the first turbulence prevention structure (515) includes a guide plate. The guide plate is installed so as to extend along the direction in which the first air outlet (413) faces the light-emitting assembly (200), thereby allowing the first inner wall (513) and / or the second inner wall (514) on which the guide plate is installed to guide currents against the wind flowing through the guide plate, thereby limiting the formation of turbulence at the location of the first inner wall (513) and / or the second inner wall (514).

[0126] The number of guide plates may be one or multiple. For example, the first turbulence prevention structure (515) may include multiple guide plates, and the multiple guide plates are arranged and installed at intervals along the length direction of the light-emitting assembly (200), for example, along the length direction of the lamp tube.

[0127] In some embodiments, the first turbulence prevention structure (515) includes a guide plate. The guide plate includes a first inclined surface (5151) and a second inclined surface (5152) installed opposite each other along the thickness direction. The first inclined surface (5151) and the second inclined surface (5152) are installed at an angle toward each other along the direction in which the first air blower (413) faces the light-emitting assembly (200), so that the thickness of the guide plate at one end approaching the light-emitting assembly (200) is greater than the thickness of the guide plate at the one end moving away from the light-emitting assembly (200). Then, it can be simply understood that the side of the guide plate facing the first air blower (413) is sharper, thereby forming a wind-breaking structure, and by reducing the wind resistance formed when the first partial wind blows past the guide plate, the heat dissipation effect is improved.

[0128] In some embodiments, the inner wall of the flow guide segment (512) includes a first flow guide surface connected to the flow guide plate. The flow guide plate further includes a third inclined surface (5153). The third inclined surface (5153) is located on one side of the flow guide plate facing away from the first flow guide surface. Here, the third inclined surface (5153) is installed at an angle along the direction in which the first air blower (413) faces the light-emitting assembly (200) and the direction in which the third inclined surface (5153) faces away from the first flow guide surface, so that the height at which the end of the flow guide plate approaches the light-emitting assembly (200) protrudes from the first flow guide surface is greater than the height at which the end of the flow guide plate faces away from the light-emitting assembly (200) protrudes from the first flow guide surface. Then, it can be simply understood that the side of the flow guide plate facing the first air blower (413) is sharper, thereby forming a wind-breaking structure, and by reducing the wind resistance formed when the first partial wind blows past the flow guide plate, the heat dissipation effect is improved.

[0129] In some embodiments, the heat dissipation assembly (400) further includes a temperature plate (42) and a heat dissipation fin (43) mounted on the temperature plate (42). One end of the temperature plate (42) is heat-conducted connected to the cold compress assembly (300). At least a portion of both the temperature plate (42) and the heat dissipation fin (43) are installed within the second heat dissipation duct (52). Here, the end of the temperature plate (42) approaching the first air outlet (413) is installed so as to be bent toward the side approaching the position of the light-emitting assembly (200), thereby forming a bending segment (421). The refractive segment (421) is extended to the position of the first air outlet (413), so that one side of the refractive segment (421) approaching the light-emitting assembly (200) and the bracket assembly (500) form at least a portion of the guide segment (512), and one side of the refractive segment (421) moving away from the light-emitting assembly (200) and the bracket assembly (500) form the inlet segment of the second heat dissipation duct (52). Alternatively, the refractive segment (421) is extended to the position of the first air outlet (413), so that one side of the refractive segment (421) approaching the light-emitting assembly (200) and the bracket assembly (500) form at least a portion of the guide segment (512), and one side of the refractive segment (421) moving away from the light-emitting assembly (200) and the bracket assembly (500) form the air outlet approach segment of the second heat dissipation duct (52).

[0130] For example, the light-emitting assembly (200) can be located at the bottom of the temperature-dissipating plate (42), and then the upper wall of the inner wall of the first heat dissipation duct (51) can be formed on the lower surface of the temperature-dissipating plate (42). In addition, by installing the temperature-dissipating plate (42) so that one end approaching the first air outlet (413) is bent downward, the bending segment (421) of the temperature-dissipating plate (42) forms the second inner wall (514) of at least a part of the flow-conducting segment (512), thereby simplifying the structure of the bracket assembly (500) and reducing the difficulty of molding the bracket assembly (500).

[0131] Continuing with reference to FIG. 8, FIG. 8 is another schematic diagram of a local enlarged view of position X in FIG. 2. In some embodiments, the heat dissipation fin (43) may include a proximal heat dissipation segment (431) and a distal heat dissipation segment (432). The proximal heat dissipation segment (431) is mounted on the refraction segment (421). The distal heat dissipation segment (432) is connected to one end of the proximal heat dissipation segment (431) that approaches the light emission region (11). Here, the width of the proximal heat dissipation segment (431) is greater than the width of the distal heat dissipation segment (432), and the width of the heat dissipation fin (43) is the distance from one side where the heat dissipation fin (43) approaches the temperature plate (42) to the other side where it moves away from the temperature plate (42).

[0132] Here, the heat dissipation fin (43) includes a connecting side (433) mounted on the temperature plate (42) and a free side (434) facing away from the temperature plate (42), and the width of the heat dissipation fin (43) is the distance from the connecting side (433) to the free side (434) of the heat dissipation fin (43).

[0133] Then, in conjunction with the downward bending of the aforementioned bending segment (421), the space formed by the downward bending of the bending segment (421) can be rationally utilized to make the proximal heat dissipation segment (431) larger, thereby expanding the contact area between the heat dissipation fin (43) and the air, thereby improving the heat dissipation effect, while also making the overall structure of the skin treatment device more compact and reducing its volume.

[0134] For example, the heat dissipation fin (43) includes a connecting side (433) mounted on the temperature plate (42) and a free side (434) facing away from the temperature plate (42). Here, the connecting side (433) and the free side (434) of the proximal heat dissipation segment (431) are installed at an angle toward each other along the direction in which the light-emitting assembly (200) faces the first air outlet (413), so that the width of the proximal heat dissipation segment (431) is gradually expanded.

[0135] In some embodiments, the housing (100) includes a light-emitting segment extending to the light-emitting region (11) at the connection location of the proximal heat-emitting segment (431) and the distal heat-emitting segment (432). Here, the cross-sectional area of ​​the light-emitting segment is gradually reduced along the direction in which the light-emitting assembly (200) faces the light-emitting region (11). This makes the cross-section of one side of the light-emitting region (11) of the case smaller, making it easier for the user to accurately attach the light-emitting region (11) to the user's skin awaiting treatment. Correspondingly, the height at which the distal heat-emitting segment (432) protrudes from the temperature plate (42) is small, and the height at which the proximal heat-emitting segment (431) protrudes from the temperature plate (42) is correspondingly larger than the height at which the distal heat-emitting segment (432) protrudes from the temperature plate (42).

[0136] In some embodiments, the number of heat dissipation fins (43) is multiple. The heat dissipation fins (43) include a connecting side (433) mounted on the temperature plate (42) and a free side (434) facing away from the temperature plate (42). The free side (434) of the multiple heat dissipation fins (43) forms a free side, and the free side includes a windproof area (435) approaching the first air outlet (413) and a circulation area (436) approaching the cold compress assembly (300). Here, the heat dissipation assembly (400) further includes a blocking part (44), and the blocking part (44) blocks the windproof area (435) so that wind between adjacent heat dissipation fins (43) flows out or flows in from the circulation area (436) approaching the cold compress assembly (300).

[0137] Then, the air within the second heat dissipation duct (52) can be made to flow to a position closer to the cold compress assembly (300), thereby improving the heat dissipation effect on the cold compress assembly (300). In addition, by installing a blocking part (44) in conjunction with the fact that one end of the aforementioned bending segment (421) approaching the first air outlet (413) is bent downward, the bending segment (421) can more effectively avoid directing the air flowing out from the first air outlet (413) position to the proximal heat dissipation segment (431) position.

[0138] In some embodiments, the blocking portion (44) is blocked at least on the free side (434) of the proximal heat dissipation segment (431). Thus, by installing the blocking portion (44), the bending segment (421) can better avoid directing the wind flowing out from the first air outlet (413) location to the proximal heat dissipation segment (431) location.

[0139] In some embodiments, along the direction in which the first air outlet (413) faces the light-emitting assembly (200), the length of the blocking portion (44) occupies more than one-third of the length of the heat dissipation fin (43). This allows the air between adjacent heat dissipation fins (43) to flow out from the circulation area (436) approaching the cold compress assembly (300).

[0140] Continuing with reference to FIG. 9, FIG. 9 is a schematic diagram of the structure of the first blocking portion at the location of the heat dissipation fins of the skin treatment device illustrated in FIG. 2. In some embodiments, the blocking portion (44) may include a windproof plate (441), and the windproof plate (441) is installed as a cover on the free side (434) of a plurality of heat dissipation fins (43).

[0141] Continuing with reference to FIG. 10, FIG. 10 is a schematic diagram of the structure of the first blocking portion at the location of the heat dissipation fin in the skin treatment device illustrated in FIG. 2. In some embodiments, the blocking portion (44) may include a plurality of foldings (442), and each folding (442) is folded and connected to the free side (434) of one of the heat dissipation fins (43). Thus, during the manufacturing process, the folding (442) can be formed on the free side (434) of the heat dissipation fin (43) through a direct folding or folding process, making the manufacturing of the heat dissipation fin (43) and the blocking portion (44) simpler and more cost-effective.

[0142] Specifically, the blocking part (44) may include only one of the windproof plate (441) and the folding (442), and the blocking part (44) may include both the windproof plate (441) and the folding (442) simultaneously, and the embodiments of the present application are not limited thereto.

[0143] A second air outlet (13) is further installed in the housing (100) and communicates with the outside of the housing (100), and the second air outlet (13) is located on one side where the heat dissipation fin (43) faces away from the temperature equalization plate (42). The second air outlet (13) is installed to correspond to the blocking part (44), and the second air outlet (13) communicates with the circulation area (436).

[0144] Thus, for example, if the first air outlet (413) is the outlet of the fan (41), the second portion of air flowing out from the first air outlet (413) can be discharged directly from the second air outlet (13) location after passing through the heat dissipation fin (43), so that the heat dissipation path of the second heat dissipation duct (52) is shorter and the flow velocity is faster. On the other hand, since the second air outlet (13) is installed to correspond to the blocking part (44), it means that the second air outlet (13) is further away from the light emission area (11), and thus the hot air discharged from the second air outlet (13) location can directly reach the skin waiting to be treated near the light emission area (11), and furthermore, the user experience of the skin treatment device can be improved.

[0145] In some embodiments, a second turbulence prevention structure (45) is installed on one side where the heat dissipation fin (43) is far from the temperature plate (42) and is used to limit the formation of turbulence on the side where the heat dissipation fin (43) is far from the temperature plate (42).

[0146] For example, the second turbulence prevention structure (45) is located in the circulation area (436) and restricts wind flowing out from the circulation area (436) from forming turbulence.

[0147] It is understandable that from the proximal heat dissipation segment (431) to the distal heat dissipation segment (432), the height of the heat dissipation fins (43) gradually decreases, or the space between the heat dissipation fins (43) gradually decreases, but the blocking part (44) allows the second portion of the wind to flow only when it flows to the distal heat dissipation segment (432) position, so turbulence is likely to form in the flow area (436) at the distal heat dissipation segment (432) position. At this time, by installing the second turbulence prevention structure (45), the flow of wind flowing out from the flow area (436) can be made smoother, thereby improving the heat dissipation effect.

[0148] In some embodiments, a second turbulence prevention structure (45) is installed on each heat dissipation fin (43), and thus, the heat dissipation effect can be improved by installing more second turbulence prevention structures (45). Of course, in some other embodiments, a second turbulence prevention structure (45) may be installed on only one or some of the heat dissipation fins (43), and the embodiments of the present application are not limited thereto.

[0149] In some embodiments, the second turbulence prevention structure (45) may include a plurality of tooth portions, and the tooth portions are installed protrudingly on one side where the heat dissipation fin (43) is facing away from the temperature plate (42). Furthermore, compared to the side where the heat dissipation fin (43) is facing away from the temperature plate (42) being flat, the tooth portions can effectively limit the formation of turbulence in the flow area (436).

[0150] In some embodiments, the second turbulence prevention structure (45) may include a plurality of tooth portions, and the tooth portions are triangular. Of course, in some other embodiments, the tooth portions may have different shapes, and the embodiments of the present application are not limited thereto.

[0151] In some embodiments, the second turbulence prevention structure (45) may be molded integrally with the heat dissipation fin (43). Of course, the second turbulence prevention structure (45) may be molded separately from the heat dissipation fin (43), and, for example, the second turbulence prevention structure (45) may be detachably connected to the heat dissipation fin (43). The embodiments of the present application are not limited thereto.

[0152] In some embodiments, a second air outlet (13) is further installed in the housing (100) and communicates with the outside of the housing (100), and the second air outlet (13) is located on one side where the heat dissipation fin (43) faces away from the temperature dissipation plate (42). One end of the first heat dissipation duct (51) that is away from the first air outlet (413) communicates with the second air outlet (13) and communicates with the outside of the housing (100). One end of the second heat dissipation duct (52) that is away from the first air outlet (413) communicates with the second air outlet (13) and communicates with the outside of the housing (100).

[0153] Continuing with reference to FIGS. 11 and FIGS. 12, FIG. 11 is a cross-sectional view along the BB direction of the skin treatment device shown in FIG. 2, and FIG. 12 is a cross-sectional view of the heat dissipation assembly and light emission assembly shown in FIG. 2. In some embodiments, a second air outlet (13) is further installed in the housing (100) and communicates with the outside of the housing (100). The second air outlet (13) is located on one side where the heat dissipation fin (43) faces away from the temperature plate (42). A third heat dissipation duct (57) is further provided on the inner wall of the housing (100). One end of the third heat dissipation duct (57) is connected to the end of the first heat dissipation duct (51) that is far from the first air outlet (413), and the other end of the third heat dissipation duct (57) and the end of the second heat dissipation duct (52) that is far from the first air outlet (413) are both connected to the second air outlet (13) and form a Bernoulli structure at the connection location.

[0154] Then, an example is given where the first air outlet (413) is the outlet of the fan (41). When the fan (41) is operated, the pressure at the outlet of the first duct, which has a faster flow rate among the third heat dissipation duct (57) and the second heat dissipation duct (52), is low, thereby drawing out or sucking out the wind within the second duct and improving the flow rate within the second duct, thereby improving the heat dissipation effect of the entire skin treatment device.

[0155] For example, when the fan (41) is operated, the gas flow rate in the second heat dissipation duct (52) may be greater than the gas flow rate in the third heat dissipation duct (57). As a result, the wind in the second heat dissipation duct (52) draws out the wind in the third heat dissipation duct (57), and furthermore, the wind in the second heat dissipation duct (52) indirectly draws out the wind in the first heat dissipation duct (51).

[0156] In some embodiments, the outlet of the third heat dissipation duct (57) approaching the second air outlet (13) is installed on the inner wall of the outlet end of the second heat dissipation duct (52), so that the wind in the second heat dissipation duct (52) can conveniently draw out the wind in the third heat dissipation duct (57).

[0157] In some embodiments, the second heat dissipation duct (52) extends from the first air outlet (413) to the second air outlet (13). The heat dissipation fin (43) is installed within the second heat dissipation duct (52), and since both the first air outlet (413) and the second air outlet (13) are adjacent to the heat dissipation fin (43), the second heat dissipation duct (52) is short. The first heat dissipation duct (51) is located on one side where the temperature plate (42) is facing away from the second air outlet (13), so the total length of the path through which the first partial wind flows within the first heat dissipation duct (51) and the third heat dissipation duct (57) is longer than the total length of the path through which the second partial wind flows within the second heat dissipation duct (52).

[0158] Continuing with reference to FIG. 13, FIG. 13 is another cross-sectional view of the skin treatment device illustrated in FIG. 1. The third heat dissipation duct (57) may include a pressure expansion chamber (571) and a communication segment (572). The pressure expansion chamber (571) is connected to the mounting segment (511) through a mounting port (516) (in other words, the pressure expansion chamber (571) is connected to the mounting segment (511) through the gap air outlet (212) and end air outlet (214) described below), and one end of the pressure expansion chamber (571) is installed extending along a direction away from the light-emitting area (11). The communication segment (572) is located on one side where the pressure expansion chamber (571) approaches the second air outlet (13). One end of the communication segment (572) is connected to the end where the pressure expansion chamber (571) is far from the light emission area (11), and the other end of the communication segment (572) is connected to the inner wall of the end where the second heat dissipation duct (52) approaches the second air outlet (13), so that both the first heat dissipation duct (51) and the second heat dissipation duct (52) are connected to the second air outlet (13) and a Bernoulli structure is formed at the connection location.

[0159] By installing the pressure expansion chamber (571) in this manner, the wind that has flowed through the light pipe and reflector (21) is allowed to flow into a large space after passing through the mounting location (516) (i.e., the gap air outlet (212) and end air outlet (214) described below), thereby reducing wind resistance and allowing the wind that has flowed through the light pipe and reflector (21) to pass more smoothly through the gap air outlet (212) and end air outlet (214) and flow into the pressure expansion chamber (571), thereby improving heat dissipation efficiency.

[0160] In some embodiments, the cross-sectional area of ​​the pressure expansion chamber (571) can be gradually reduced along the direction away from the light emission area (11), thereby increasing the gas flow rate within the pressure expansion chamber (571) and improving the heat dissipation effect for the light emission assembly (200).

[0161] Correspondingly, the circuit board (61) may form a portion of the inner wall of the pressure expansion chamber (571) or may be installed in part within the pressure expansion chamber (571) so that the electrically conductive bracket (62) is installed within the pressure expansion chamber (571).

[0162] Accordingly, since the total length of the first portion of wind flowing within the first heat dissipation duct (51) and the second heat dissipation duct (52) is large, the flow velocity of the first portion of wind is slowed down, and thereby the wind within the second heat dissipation duct (52) draws out the wind within the third heat dissipation duct (57), and finally, the wind within the second heat dissipation duct (52) indirectly draws out the wind within the first heat dissipation duct (51).

[0163] Of course, in conjunction with the fact that the height of the heat dissipation fin (43) in the second heat dissipation duct (52) described above gradually decreases from the proximal heat dissipation segment (431) to the distal heat dissipation segment (432), when the air intake volume of the second heat dissipation duct (52) is constant, the wind speed at the outlet position of the second heat dissipation duct (52) also increases correspondingly, thereby causing the wind in the second heat dissipation duct (52) to draw out the wind in the third heat dissipation duct (57), and finally, the wind in the second heat dissipation duct (52) indirectly draws out the wind in the first heat dissipation duct (51).

[0164] In some embodiments, the air intake volume at the inlet of the first heat dissipation duct (51) is smaller than the air intake volume at the inlet of the second heat dissipation duct (52), or the air intake volume at the end of the first heat dissipation duct (51) communicating with the first air outlet (413) is smaller than the air intake volume at the end of the second heat dissipation duct (52) communicating with the first air outlet (413), thereby allowing the wind speed at the outlet position of the second heat dissipation duct (52) to be greater, furthermore, the wind inside the second heat dissipation duct (52) draws out the wind inside the third heat dissipation duct (57), and finally, the wind inside the second heat dissipation duct (52) indirectly draws out the wind inside the first heat dissipation duct (51).

[0165] More importantly, in order to secure the cold compress effect of the cold compress assembly (300) and to implement the freezing point cold compress effect, the amount of heat generated from the cooling sheet (32) must be discharged quickly in a timely manner, and this must be ensured so that the second heat dissipation duct (52) has sufficient air volume and air velocity to quickly remove the amount of heat generated from the cooling sheet (32) through the heat dissipation fins (43) and the temperature equalization plate (42) in a timely manner. In other words, the present application can realize that the amount of heat generated in the cooling sheet (32) is removed quickly and in a timely manner through the heat dissipation fins (43) and the temperature equalization plate (42) by rationally distributing the amount of air from the fan by making the amount of air from the inlet of the first heat dissipation duct (51) smaller than the amount of air from the inlet of the second heat dissipation duct (52), thereby improving the cold compress effect of the cold compress assembly (300) and implementing a freezing point cold compress that can lower the cold compress temperature of the cold compress assembly (300) to 0 degrees or 0 degrees or lower (minus 5 degrees, etc.).

[0166] For example, the first heat dissipation duct (51) approaches the first air outlet (413) and the first heat dissipation duct (51) approaches the first air outlet (413) and the second heat dissipation duct (52); where, the area of ​​the corresponding region of the first air outlet (413) to the first heat dissipation duct (51) is smaller than the area of ​​the corresponding region of the first air outlet (413) to the second heat dissipation duct (52), and thus the amount of air entering the first heat dissipation duct (51) is smaller than the amount of air entering the second heat dissipation duct (52).

[0167] Specifically, the first air outlet (413) includes a first side (411) approaching the first heat dissipation duct (51) and a second side (412) approaching the second heat dissipation duct (52), and the first side (411) and the second side (412) are installed facing each other. Here, the distance from the classification structure (42a) to the first side (411) is smaller than the distance to the second side (412), or the distance from the end of the bending segment (421) approaching the first air outlet (413) to the first side (411) is smaller than the distance to the second side (412), thereby the air intake volume at the inlet of the first heat dissipation duct (51) is smaller than the air intake volume at the inlet of the second heat dissipation duct (52).

[0168] In conjunction with FIGS. 14 and 15, FIG. 14 is a cross-sectional view along the CC direction of the skin treatment device illustrated in FIG. 2, and FIG. 15 is a local enlarged view of the Z position in FIG. 14. In some embodiments, a mounting hole (516) is installed on the inner wall of the first heat dissipation duct (51). The light-emitting assembly (200) is mounted within the first heat dissipation duct (51) through the mounting hole (516) and forms a gap (212) with the inner wall of the mounting hole (516). The light-emitting assembly (200) includes a reflective member (21) and a light source (22). The light source (22) is installed within the reflective member (21). A side air outlet (213) is installed on the periphery of the reflective member (21), and the side air outlet (213) is connected to the first heat dissipation duct (51), and an end air outlet (214) is further installed at the end of the reflective member (21).

[0169] Thus, when the first air outlet (413) is, for example, the air outlet of the fan (41), some of the wind within the first heat dissipation duct (51) can be blown directly onto the surface of the reflective member (21), and other parts can be introduced into the reflective member (21), thereby expanding the heat dissipation area of ​​the light-emitting assembly (200) and thereby improving the heat dissipation effect for the light-emitting assembly (200).

[0170] In some embodiments, the mounting port (516) is connected to one end where the third heat dissipation duct (57) approaches the first heat dissipation duct (51), and the one end where the third heat dissipation duct (57) moves away from the first heat dissipation duct (51) is connected to the one end where the second heat dissipation duct (52) moves away from the first air outlet (413). The end air outlet (214) is connected to the mounting port (516) or the third heat dissipation duct (57).

[0171] Thus, when the first air outlet (413) is the outlet of the fan (41), for example, some of the wind within the first heat dissipation duct (51) is blown directly onto the surface of the reflective member (21) and then sequentially discharged through the gap air outlet (212), the third heat dissipation passage, the outlet end of the second heat dissipation passage, and the second air outlet (13); and other parts of the wind within the first heat dissipation duct (51) are blown directly into the interior of the reflective member (21) through the side air outlet (213) and then sequentially discharged through the end air outlet (214), the third heat dissipation duct (57), the outlet end of the second heat dissipation duct (52), and the second air outlet (13).

[0172] In some embodiments, the end air blower (214) is installed adjacent to the gap air blower (212) to form a Bernoulli structure.

[0173] For example, the light source (22) includes a lamp tube. A reflective member (21) is installed on the outer side where the lamp tube is installed. Here, along the longitudinal direction of the lamp tube, the end of the reflective member (21) penetrates the mounting hole (516), and the outer wall of the reflective member (21) and the inner wall of the mounting hole (516) form a gap air hole (212). Along the longitudinal direction of the lamp tube, an end air hole (214) is formed between the inner wall of the reflective member (21) and the lamp tube, so that the gap air hole (212) and the end air hole (214) form a Bernoulli structure.

[0174] Then, for example, when the fan (41) is operated, the pressure intensity at the outlet position with the faster flow rate among the end air outlet (214) and the gap air outlet (212) is low, thereby drawing out or sucking out the wind within the flow path corresponding to the other outlet, thereby improving the heat dissipation effect of the entire skin treatment device.

[0175] Specifically, since the flow path of the wind introduced into the reflective member (21) is more curved and longer, when the fan (41) is operated, the wind velocity flowing from outside the reflective member (21) to the gap air outlet (212) position is greater than the wind velocity at the end air outlet (214) position, thereby drawing out the wind inside the reflective member (21).

[0176] Then, in conjunction with forming different position Bernoulli structures at the outlet of the second heat dissipation duct (52) and the outlet of the third heat dissipation duct (57) described above, the skin treatment device in the embodiment of the present application improves the heat dissipation effect by improving the flow velocity of the wind inside the reflective member (21) through a double Bernoulli structure.

[0177] In some embodiments, the number of gap air holes (212) may be one or multiple. For example, at least one protrusion may be formed on the inner wall of the mounting member (516), and at least one protrusion abuts the outer wall of the reflective member (21), thereby blocking multiple or at least two gap air holes (212) between the inner wall of the mounting member (516) and the outer wall of the reflective member (21).

[0178] In some embodiments, the light-emitting area (11) and the first blower (413) are located on opposite sides in the circumferential direction of the lamp tube and are installed opposite each other.

[0179] For example, the light emission area (11) may be located at the front side of the lamp tube, and the first blower (413) may be located at the rear side of the lamp tube.

[0180] In some embodiments, openings facing the light-emitting area (11) are formed on both sides in the circumferential direction of the reflective member (21) to collect light rays generated from the lamp tube and irradiate them onto the light-emitting area (11), and side air outlets (213) are installed on at least one side in the circumferential direction of the reflective member (21).

[0181] For example, both sides of the reflective member (21) may face forward, thereby forming an opening facing forward. At this time, side air vents (213) may be installed on both the upper side and the lower side of the front of the reflective member (21).

[0182] Specifically, the reflective member (21) may be a reflective cup.

[0183] In conjunction with the above-described flow segment (512) comprising a first inner wall (513) and a second inner wall (514), one side of the reflective member (21) in the circumferential direction is adjacent to the first inner wall (513), thereby allowing the first inner wall (513) to guide some of the wind to the adjacent side air outlet (213). The other side of the reflective member (21) in the circumferential direction is adjacent to the second inner wall (514), thereby allowing the second inner wall (514) to guide some of the wind to the adjacent side air outlet (213).

[0184] In some embodiments, the inner wall of the first heat dissipation duct (51) has a mounting member (516) installed at at least one end in the longitudinal direction of the pipe. The mounting member (516) located on the opposite side in the longitudinal direction of the pipe is connected to the second heat dissipation duct (52) through a different third heat dissipation duct (57).

[0185] For example, if the length direction of the pipe is left-right, a mounting hole (516) can be installed on both the left wall and the right wall of the inner wall of the first heat dissipation duct (51), and each mounting hole (516) is connected to a third heat dissipation duct (57).

[0186] Continuing with reference to FIG. 16, FIG. 16 is a schematic diagram of the first circuit board assembly of the skin treatment device illustrated in FIG. 2. In some embodiments, the skin treatment device further comprises a circuit board assembly (600), and the circuit board assembly (600) comprises a circuit board (61) and an electrically conductive bracket (62). The circuit board (61) is installed within the housing (100). The electrically conductive bracket (62) is mounted on the circuit board (61).

[0187] Correspondingly, the light-emitting assembly (200) includes a light source (22), and the light source (22) is mounted on an electrically conductive bracket (62), supported by the electrically conductive bracket (62), and forms an electrical connection with a circuit board (61).

[0188] For example, the light-emitting assembly (200) may include a light tube, and the end of the light tube is connected to an electrically conductive bracket (62), so that the light tube is supported by a circuit board (61) and electrically connected to the circuit board (61).

[0189] In some embodiments, the circuit board (61) and the bracket assembly (500) form a third heat dissipation duct (57), and the electrically conductive bracket (62) is positioned within the third heat dissipation duct (57), thereby fully utilizing the third heat dissipation duct (57) to proceed with the mounting and fixing of the tube, making the overall structure of the skin treatment device more compact.

[0190] In some embodiments, the light source (22) has, for example, at least two light tubes, and at least two light sources (22) are installed at intervals.

[0191] Furthermore, the management effect of the skin care device can be improved through a method in which multiple light sources (22) emit light. For example, multiple light sources (22) can be turned on and off in synchronization, thereby allowing the light source (22) assembly to perform skin care at a higher maximum power rate, thereby improving the management effect of the skin care device; or, different light sources (22) can emit light individually or in combination, so that the light source (22) assembly can have at least three light emission modes, making it convenient to adjust to a more suitable light emission mode according to the user's actual needs, and further improving the management effect of the skin care device.

[0192] For example, when multiple light sources (22) are switched on and off in synchronization, the first stage of all light sources (22) can be mounted on the same electrically conductive bracket (62) and electrically connected to the circuit board (61), and the second stage of all light sources (22) can be mounted on different electrically conductive brackets (62) and electrically connected to the circuit board (61).

[0193] Specifically, the first stage of the light source (22), for example, the lamp tube, may be the positive electrode and the second stage the negative electrode, or the first stage of the light source (22), for example, the lamp tube, may be the negative electrode and the second stage the positive electrode. In that case, it can be understood that the positive electrodes of all light sources (22) are all electrically connected to the circuit board (61) through the same electrically conductive bracket (62), and the negative electrodes of all light sources (22) are all electrically connected to the circuit board (61) through different electrically conductive brackets (62), thereby allowing the current transmission between the circuit board (61) and all light sources (22) to be more consistent, further improving the consistency of light emission of all light sources (22), and finally further enhancing the care effect of the skin care device.

[0194] Below, we will continue to interpret and explain the technical methods for the embodiments of the present application, such as the different light sources (22) being able to emit light individually or in combination.

[0195] Continuing with reference to FIG. 17, FIG. 17 is a schematic diagram of a second circuit board assembly of the skin treatment device illustrated in FIG. 2. At least two light sources (22) may include a first light source (221) and a second light source (222). Thus, at least three different light emission modes can be realized through the first light source (221) and the second light source (222). Of course, the number of light sources (22) may be three, four, five, or six, and thus the first light source (221) and the second light source (222) may be any two of the plurality of light sources (22), and the embodiments of the present application are not limited thereto.

[0196] The electrically conductive bracket (62) includes a first electrically conductive bracket (621), a second electrically conductive bracket (622), and a third electrically conductive bracket (623). Here, the positive electrodes of the first light source (221) and the second light source (222) are both electrically connected to the third electrically conductive bracket (623). The negative electrode of the first light source (221) is electrically connected to the first electrically conductive bracket (621), and the negative electrode of the second light source (222) is electrically connected to the second electrically conductive bracket (622).

[0197] Then, the third electrically conductive bracket (623) may be understood as a common anode, thereby reducing the number of electrically conductive brackets (62) required between the light source (22) and the circuit board (61), simplifying the structure of the skin care device and reducing the difficulty of assembly and production cost of the skin care device.

[0198] Here, it is further understood that the circuit board (61), the third electrically conductive bracket (623), the first light source (221), and the first electrically conductive bracket (621) form the first circuit bracket, and the circuit board (61), the third electrically conductive bracket (623), the second light source (222), and the second electrically conductive bracket (622) form the second circuit bracket. In this way, by installing a switch at a corresponding position on the first electrically conductive bracket (621) and installing another switch at a corresponding position on the second electrically conductive bracket (622), independent control of the first light source (221) and the second light source (222) can be realized.

[0199] Alternatively, the electrically conductive bracket (62) may include a first electrically conductive bracket (621), a second electrically conductive bracket (622), and a third electrically conductive bracket (623). The negative electrodes of the first light source (221) and the second light source (222) are both electrically connected to the third electrically conductive bracket (623), the positive electrode of the first light source (221) is electrically connected to the first electrically conductive bracket (621), and the positive electrode of the second light source (222) is electrically connected to the second electrically conductive bracket (622).

[0200] Then, the third electrically conductive bracket (623) may be understood as a common cathode, thereby reducing the number of electrically conductive brackets (62) required between the light source (22) and the circuit board (61), simplifying the structure of the skin care device and reducing the difficulty of assembly and production cost of the skin care device.

[0201] Here, it is further understood that the circuit board (61), the third electrically conductive bracket (623), the first light source (221), and the first electrically conductive bracket (621) form the first circuit bracket, and the circuit board (61), the third electrically conductive bracket (623), the second light source (222), and the second electrically conductive bracket (622) form the second circuit bracket. In this way, by installing one switch at a corresponding position of the first electrically conductive bracket (621) and another switch at a corresponding position of the second electrically conductive bracket (622), independent control of the first light source (221) and the second light source (222) can be realized.

[0202] Continuing with Fig. 18, Fig. 18 is a schematic diagram of a third circuit board assembly of the skin treatment device illustrated in Fig. 2. Of course, in some other embodiments, the number of electrically conductive brackets (62) is multiple. Different light sources (22) are mounted on the circuit board (61) through different electrically conductive brackets (62). This ensures that even if one electrically conductive bracket (62) is detached or damaged, the remaining electrically conductive brackets (62) can continue to supply electricity to the corresponding light source (22), thereby ensuring that other light sources (22) of the skin care device can operate normally. More importantly, such an installation increases the light output power (e.g., hair removal power) and / or the variety of light output functions (e.g., hair removal function variety). In other words, by installing at least two light sources (22) and mounting and fixing each of the at least two light sources (22) to a circuit board (61) through different electrically conductive brackets (62), multiple light sources (22) can be turned on simultaneously when an increase in hair removal power is required, and one of the light sources (22) can be turned on when it is not required; or at least two of the light sources (22) may alternately emit light to improve the light output power while reducing or not increasing the consumption of a single light source (22).

[0203] In some embodiments, the light-emitting assembly (200) further includes a reflective member (21), and the reflective member (21) is installed surrounding the light tube. The reflective member (21) is electrically connected to a circuit board (61), and the distance between the reflective member (21) and the light tube is smaller than a preset distance so that the reflective member (21) can excite the light tube.

[0204] For example, the tube may be a xenon tube, and both ends or the positive end of the xenon tube are electrically connected to a circuit board (61) through an electrically conductive bracket (62). At this time, the circuit board (61) may be excited through a reflective member (21) or may excite the tube, thereby reducing the parts of the skin treatment device through the redundant use of the reflective member (21), making the skin treatment device more compact.

[0205] In some embodiments, the preset distance may be 2 mm or less. For example, the distance between the reflective member (21) and the lamp is 2 mm, 1.4 mm, 0.5 mm, or 0 mm. Of course, if the distance between the reflective member (21) and the lamp is 0 mm, it may be understood that the reflective member (21) is in direct contact with the lamp.

[0206] Optionally, in some embodiments, a wire (e.g., a filament) may be wound around the surface of the tube and electrically connected to a circuit board (61) to be used to excite the tube, and the embodiments of the present application are not limited thereto.

[0207] In some embodiments, the circuit board assembly (600) further includes an isolation member (63). The isolation member (63) is sleeved to at least one of the light tube and the electrically conductive bracket (62), and the isolation member (63) isolates the reflective member (21) and the electrically conductive bracket (62). Here, the isolation member (63) and the mounting member (516) are installed with a gap to form an exhaust gap. By doing so, the reflection member (21) and the electrically conductive bracket (62) for exciting the light tube through the isolation member (63) can avoid forming a short circuit, thereby improving the reliability and safety of the skin treatment device.

[0208] The isolation member (63) may be an insulating material such as plastic, rubber, or ceramic, and the embodiments of the present application are not limited thereto.

[0209] As illustrated in FIG. 13, in some embodiments, the light-emitting assembly (200) includes a light tube. The light tube is mounted on a mounting segment (511). The inner wall of the guide segment (512) further includes a third inner wall (517) and a fourth inner wall (518), and both the third inner wall (517) and the fourth inner wall (518) are connected between the first inner wall (513) and the second inner wall (514). The third inner wall (517) and the fourth inner wall (518) are each located at different ends in the longitudinal direction of the light tube. Here, along the direction in which the first air outlet (413) faces the light-emitting assembly (200), at least one of the third inner wall (517) and the fourth inner wall (518) is installed at an angle toward the other so that the first partial wind guides the light-emitting assembly (200).

[0210] It can be understood that, in the actual operation process, the main heat of the lamp is concentrated in the middle part along the length of the lamp, and for example, if the first air outlet (413) is the air outlet of the fan (41), the first portion of the wind can be concentrated in the middle of the lamp through the third inner wall (517) and the fourth inner wall (518), thereby achieving a more superior heat dissipation effect.

[0211] For example, in the longitudinal direction of the light tube, the length of the section where the flow segment (512) approaches the light-emitting assembly (200) is shorter than the length of the light tube, thereby concentrating the first portion of the wind through the third inner wall (517) and the fourth inner wall (518) in the middle of the light tube.

[0212] In some embodiments, at least one third heat dissipation duct (57) is further installed in the bracket assembly (500). The third heat dissipation duct (57) is installed on one side where the third inner wall (517) faces away from the fourth inner wall (518) and / or on one side where the fourth inner wall (518) faces away from the third inner wall (517). The third heat dissipation duct (57) is installed extending from the first inner wall (513) toward the second inner wall (514). One end of the third heat dissipation duct (57) is connected to the outlet end of the first heat dissipation duct (51). The other end of the third heat dissipation duct (57) is connected to the second heat dissipation duct (52).

[0213] Thus, the third heat dissipation duct (57) can be positioned by fully utilizing the evacuation space formed by the third inner wall (517) and / or the fourth inner wall (518) sloping inward, making the overall structure of the skin treatment device more compact.

[0214] Additionally, as the third inner wall (517) and the fourth inner wall (518) are inclined inward, the width of the third heat dissipation duct (57) can be gradually reduced as the light-emitting assembly (200) follows the direction toward the first air outlet (413), thereby realizing a pressure acceleration effect on the airflow.

[0215] Continuing with reference to FIG. 19, FIG. 19 is a schematic diagram of the structure of an IGBT element of the skin treatment device illustrated in FIG. 2. In some embodiments, the circuit board assembly (600) may further include an IGBT element (64). The IGBT element (64) is mounted on the circuit board (61). The angle between one side surface of the IGBT element (64) in the thickness direction and the circuit board (61) is 45° or greater and 90° or less.

[0216] For example, the angle between one side surface in the thickness direction of the IGBT element (64) and the circuit board (61) may be 45°, 49°, 57.8°, 66.9°, 75.4°, 85°, or 90°, and the embodiments of the present application are not limited thereto.

[0217] Then, compared to one side surface in the thickness direction of the IGBT element (64) being in close contact with the circuit board (61), in the embodiment of the present application, a large gap is formed between the IGBT element (64) and the circuit board (61), thereby increasing the contact area between the IGBT element (64) and the air, and finally improving the heat dissipation effect for the IGBT element (64).

[0218] For example, the IGBT element (64) is mounted vertically on the circuit board (61). As a result, the angle between one side surface in the thickness direction of the IGBT element (64) and the circuit board (61) becomes approximately 90°.

[0219] In some embodiments, a fan (41) is used to cause air within the housing to flow out from an outlet on the housing (100) along a predetermined path. At least a portion of the IGBT elements (64) is located along the predetermined path. This allows the heat dissipation effect of the IGBT elements (64) to be further enhanced through the fan (41).

[0220] For example, the fan (41) can be mounted on the circuit board (61). An IGBT element (64) is installed in proximity to the fan (41). Then, the air intake of the fan (41) can draw in surrounding air, thereby forming at least a portion of a planned path in the space surrounding the fan (41). Correspondingly, by installing the IGBT element (64) in proximity to the fan (41), it is realized that at least a portion is mounted in the planned path.

[0221] In some embodiments, the circuit board (61) is installed along the longitudinal direction of the housing (100). The circuit board (61) has a first side edge and a second side edge extending along the longitudinal direction, and an IGBT element (64) is located between the fan (41) and the first side edge, and the IGBT element (64) is installed close to the first side edge.

[0222] Then, the first side edge and the second side edge can each approach both surfaces in the width direction of the housing (100) and each can also approach both surfaces in the thickness direction of the housing. In addition, since the IGBT element (64) is installed by approaching the first side edge, the space between the fan (41) and the first side edge can be reasonably utilized to mount the IGBT element (64), which is advantageous for the miniaturization design of the skin treatment device.

[0223] At this time, the IGBT element (64) described above is installed in close proximity to the fan (41), and in conjunction with the fact that the IGBT element (64) can be mounted vertically, the heights of the IGBT element (64) and the fan (41) can be roughly aligned, and thereby the space in the thickness direction of the housing (100) is rationally utilized on one side where the fan (41) faces the first side edge, which is advantageous for the miniaturization design of the skin treatment device.

[0224] In some embodiments, one surface along the thickness direction of the IGBT element (64) may face the fan (41). It is understandable that the volume of the fan (41) is large, and the space occupied by the fan (41) in the longitudinal direction of the housing (100) is correspondingly large. In this case, by making one surface along the thickness direction of the IGBT element (64) face the fan (41), the space in the longitudinal direction of the housing (100) is rationally utilized on the side where the fan (41) faces the first side edge, which is advantageous for the miniaturization design of the skin treatment device.

[0225] Continuing with FIG. 20, FIG. 20 is a schematic diagram of the structure of another fan of the skin treatment device illustrated in FIG. 2. In some embodiments, the fan (41) may be installed at an angle to the circuit board (61). Thus, for example, by mounting the fan (41) on the upper side of the circuit board (61), the gap between the bottom of the fan (41) and the circuit board (61) is larger, and thus a larger area of ​​the upper surface of the circuit board (61) can be used for heat dissipation, wiring, or mounting of electronic components, etc., which is advantageous for the miniaturization design of the skin treatment device.

[0226] In some embodiments, the number of air intakes or third air intakes (414) of the fan (41) is at least two, and the third air intake (414) is installed on one side where the fan (41) faces away from the circuit board (61), and the third air intake (414) is installed on the side where the fan (41) approaches the circuit board (61), thereby increasing the air intake volume of the fan (41) and thereby improving the heat dissipation effect.

[0227] Continuing with reference to FIGS. 21 and FIGS. 22, FIG. 21 is a schematic diagram of the structure of a skin treatment device shown in FIG. 1 at a different viewing angle, and FIG. 22 is a cross-sectional view of the skin treatment device shown in FIG. 21 along the DD direction. In some embodiments, a first display area (16) is further installed in the housing (100), and the first display area (16) has a plurality of indication formats. The skin treatment device further includes a first light source assembly (613). The first light source assembly (613) is installed within the housing (100), and the first light source assembly (613) generates a light beam emitted from the first display area (16) and is used to indicate the status of the skin treatment device. Here, the first light source assembly (613) is configured to indicate whether the skin treatment device and the skin are bonded by turning on and off, and is configured to display level information of the skin treatment device through an indication format displayed in the first display area (16). This makes it convenient for the user to observe the usage status of the skin treatment device and improves the user experience. Additionally, the light source assembly of the skin treatment device can be reduced, thereby lowering the cost of the skin treatment device.

[0228] In some embodiments, a hair removal power control circuit may be further installed in the skin treatment device, and the hair removal power control circuit is used to control the power of the light-emitting assembly (200) or the level of the skin treatment device. The hair removal power control circuit is also electrically connected to the first light source assembly (613), so that the first light source assembly (613) may be configured to display level information of the skin treatment device by displaying an indication format in the first display area (16).

[0229] In some embodiments, the skin treatment device may further include a hair removal power control circuit, and the hair removal power control circuit is used to control the power of the light-emitting assembly (200) or the level of the skin treatment device. The hair removal power control circuit is also electrically connected to the first light source assembly (613), so that the first light source assembly (613) may be configured to display level information of the skin treatment device by displaying an indication format in the first display area (16).

[0230] In some embodiments, the skin treatment device may further include a bonding detection circuit. The bonding detection circuit is used to detect whether the skin is bonded to the light-emitting area (11). For example, the bonding detection circuit includes a sensor for detecting whether the skin is bonded to the light-emitting area (11). The sensor may be an electrode piece, a proximity light sensor, a microswitch, an ultrasonic sensor, etc., and the embodiments of the present application are not limited thereto.

[0231] In some embodiments, the first display area (16) includes a plurality of first sub-display areas (161). The first light source assembly (613) includes a plurality of light-emitting elements. The first light source assembly (613) is used to illuminate a different number of first sub-display areas (161) by emitting light through a different number of light-emitting elements, thereby causing the first display area (16) to display a different indication format.

[0232] For example, the housing (100) may have a longitudinal direction, and a plurality of first sub-display areas (161) are arranged and installed along the longitudinal direction of the housing (100). A plurality of light-emitting elements are also arranged and installed along the longitudinal direction of the housing (100), and each first sub-display area (161) is installed to correspond to one or a plurality of light-emitting elements. Then, by controlling the light-emitting elements in the longitudinal direction of the housing (100) to emit light, a different number of first sub-display areas (161) are illuminated, thereby causing the first display area (16) to display a different indication format.

[0233] In some embodiments, at least two functions, such as indicating whether the light-emitting area (11) and the skin are in contact and indicating level information, can be indicated through the display of the first display area (16); in other words, the first function (e.g., whether the skin is in contact) can be indicated through the turning on and off of the first display area (16), and the second function (level) can be indicated through the display area / quantity / ratio, etc. of the first display area (16).

[0234] For example, when the light-emitting area (11) is bonded to the skin and the level information of the skin processing device is level 1, one first sub-display area (161) can be illuminated, and thus the first display area (16) displays a first indication format. When the light-emitting area (11) is bonded to the skin and the level information of the skin processing device is level 2, two first sub-display areas (161) can be illuminated, and thus the first display area (16) displays a second indication format. When the light-emitting area (11) is bonded to the skin and the level information of the skin processing device is level 3, three first sub-display areas (161) can be illuminated, and thus the first display area (16) displays a third indication format. However, if the light-emitting area (11) is not bonded to the skin, all first sub-display areas (161) are not turned on, that is, the first display area (16) is not turned on, indicating non-bonding.

[0235] Alternatively, a plurality of first sub-display areas (161) may be arranged along either a circumferential direction or another curved direction, and embodiments of the present application are not limited thereto.

[0236] In some embodiments, the skin treatment device may further include a control button (700). The control button (700) is installed in the housing (100), with a portion exposed from the housing (100), and the control button (700) is used to control the operation of the skin treatment device.

[0237] In some embodiments, a second display area (71) is provided in an area where the control button (700) and / or the housing (100) approaches the control button (700), and the second display area (71) is used to indicate whether the power of the skin treatment device is connected.

[0238] Thus, when the user controls the operation of the skin treatment device via the control button (700), it is convenient to observe the second display area (71) to check whether the power of the skin treatment device is connected, and furthermore, the user can avoid mistaking the skin treatment device for damage or incomplete skin treatment when the skin treatment device is not connected to power. It is also understandable that if the second display area (71) is located on the control button (700), the need to make holes in the surface of the housing (100) may be reduced, thereby making the appearance of the housing (100) more concise and aesthetically pleasing.

[0239] In some embodiments, the skin treatment device may further include a second light source assembly (616). The second light source assembly (616) is installed within the housing (100). The second light source assembly (616) is used to generate a light beam displayed in the second display area (71).

[0240] For example, the second light source assembly (616) may be an LED, a tungsten bulb, etc., and the embodiments of the present application are not limited thereto.

[0241] In some embodiments, the housing (100) has a longitudinal direction and the housing (100) includes a panel (14) that is installed extending along the longitudinal direction, and the first display area (16) and the second display area (71) are installed spaced apart and are both installed on the panel (14).

[0242] For example, the housing (100) may be in the shape of a strip, and if so, the first display area (16) and the second display area (71) may be located on the same side in the width or thickness direction of the housing (100). Accordingly, when a user holds one end of the housing (100) in the longitudinal direction, the first display area (16) and the second display area (71) can be conveniently observed.

[0243] It is further understandable that the second display area (71) is installed on the panel (14), and the second display area (71) may be directly molded onto the panel (14), or the second display area (71) may be installed on the control button (700), or the control button (700) may be installed indirectly onto the panel (14) by being installed on the panel again, and the embodiments of the present application are not limited thereto.

[0244] In some embodiments, the panel (14) may be covered and installed on the first light source assembly (613) and / or the second light source assembly (616). The panel (14) locally emits light to form the first display area (16) and / or the second display area (71).

[0245] For example, the panel (14) may include a light-transmitting plate member. The light-transmitting plate member has a light-transmitting area and a light-blocking area. A light-blocking structure, such as a light-blocking layer, is installed in the light-blocking area, and the light-transmitting area forms the first display area (16) and / or the second display area (71) described above. Then, not only is the light from the first light source assembly (613) and / or the second light source assembly (616) realized through the light-transmitting area, but the light rays generated from the first light source assembly (613) and / or the second light source assembly (616) are diffused disorderly, and the aesthetics of the housing (100) can also be improved by blocking the structure around the first light source assembly (613) and / or the second light source assembly (616).

[0246] In some embodiments, the light-transmitting area of ​​the panel (14) forms a first display area (16). A mounting hole may be further provided in the panel (14), a control button (700) passes through the mounting hole, and a second display area (71) is installed on the control button (700).

[0247] Alternatively, the first display area (16) and / or the second display area (71) may be an opening structure on the surface of the housing (100), and embodiments of the present application are not limited thereto.

[0248] In the embodiments described above, the description of each embodiment has its own emphasis, and for parts not described in detail in some embodiments, reference may be made to the relevant descriptions in other embodiments.

[0249] In some embodiments, the housing (100) has a longitudinal direction, a width direction, and a thickness direction. The light emission area (11) is located at one end of the housing (100), the longitudinal direction of the light tube coincides with the width direction of the housing (100), and the air intake ends of the first heat dissipation duct (51) and the second heat dissipation duct (52) are spaced apart along the thickness direction of the housing (100). The housing (100) further comprises a back plate extending along the longitudinal direction, and a housing air intake and a housing air outlet are provided on the back plate of the housing (100), the housing air intake is connected to the air intake of the fan (41), and the housing air intake is connected to the air outlet ends of the first heat dissipation duct (51) and the second heat dissipation duct (52).

[0250] The skin treatment device provided in the embodiments of the present application is described in detail above. The description of the embodiments above is merely intended to aid in understanding the method and core concept of the present application. Furthermore, those skilled in the art may modify all specific embodiments and scopes of application in accordance with the concept of the present application. In summary, the contents of this specification should not be interpreted as a limitation on the present application.
