If the specific posture changes, the directional indication will also change accordingly.

[0039] It should also be noted that when an element is referred to as being "fixed on" or "disposed on" another element, it may be directly on the other element or there may be an intermediate element at the same time. When an element is referred to as being "connected to" another element, it may be directly connected to the other element or there may be an intermediate element at the same time.

[0040] In addition, the descriptions of "first", "second", etc. in the present utility model are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in this field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present utility model.

[0041] Based on the technical problem that light therapy beauty devices in the prior art have poor heat dissipation performance, the embodiment of the utility model proposes a light therapy beauty device that can improve the heat dissipation performance and enhance the heat dissipation effect. Optionally, the light therapy beauty device is a milk light beauty device.

[0042] Reference Figures 1 to 4 The phototherapy beauty device includes a working part 100 for skin care and an operating part 200 connected to the working part 100, wherein the operating part 200 is provided with a main control circuit board 300 and a heat dissipation fan 400, and the working part 100 is provided with a light-emitting component 110 electrically connected to the main control circuit board 300, and the heat dissipation fan 400 is electrically connected to the main control circuit board 300 for dissipating heat to the light-emitting component 110;

[0043] The operating portion 200 includes: a second housing 210 , and the heat dissipation fan 400 is at least located in the middle space of the second housing 210 and passes through the central axis Z of the second housing 210 .

[0044] like Figure 1As shown, the working part 100 is mainly used as a beauty head of a phototherapy beauty instrument, which is used to fit or approach human skin during the beauty process to perform beauty and skin care on the human body. Among them, the working part 100 may include a first shell 120, and the shape of the first shell 120 may be a regular shape (such as a cylinder, a table, a cone, a sphere, etc.), or an atypical shape, which can be set according to actual conditions. The light-emitting component 110 is arranged in the first shell 120 of the working part 100, and emits light to the user's skin to perform whitening, skin rejuvenation and other care. The structural composition of the light-emitting component 110 can be in various forms. For example, the light-emitting component 110 includes a light-emitting lamp and other components (such as a filter component, a reflective component, etc.) that cooperate with the light-emitting lamp, including but not limited to this. Among them, the light emitted by the light-emitting component 110 is filtered by the filter component, and various bands of care light can be output. Specifically, a suitable filter component can be selected according to needs. For example, red light can promote the repair of skin collagen fibrils, blue light can treat acne and superficial fungal infections, green light can stimulate skin collagen regeneration and remove wrinkles, and near-infrared light can penetrate deep into the skin, reaching the shallow to middle layers of the dermis, effectively heating the water molecules in the dermis, stimulating collagen proliferation and reorganization, thereby making the skin firm, smooth and elastic.

[0045] The operating part 200 is used for the user to hold it. The operating part 200 and the working part 100 are detachably connected (such as snap connection, screw connection, etc.) or integrally arranged. The user can control the phototherapy beauty instrument to perform skin care operations by holding the operating part 200. Among them, the shape of the operating part 200 can be various, such as roughly disc-shaped. The main control circuit board 300 and the heat dissipation fan 400 are arranged in the operating part 200. The main control circuit board 300 is used to send control signals to the working devices of the phototherapy beauty instrument (such as the heat dissipation fan 400, the light-emitting component 110, etc.) and receive feedback status data, etc., including but not limited to this. The heat dissipation fan 400 is used to air-cool the components or devices (such as the light-emitting component 110) in the phototherapy beauty instrument. Among them, the heat dissipation fan 400 can be a blowing fan or an exhaust fan, which can be set according to actual conditions.

[0046] Specifically, Figure 2 and Figure 4As shown, the operating part 200 includes a second housing 210, and a space is formed inside the second housing 210. In the second housing 210, the heat dissipation fan 400 is at least located in the middle space of the second housing 210 and passes through the central axis Z of the second housing 210, that is, the internal space of the second housing 210 is divided into most parts (such as 3 / 5 space, 2 / 3 space) for setting the heat dissipation fan 400, and the heat dissipation fan 400 is installed in the main middle space position of the internal space of the second housing 210, and passes through the central axis Z of the second housing 210 at the same time. The heat dissipation fan 400 occupies most of the internal space of the second housing 210, so that the heat dissipation fan 400 can use a larger fan, and the large-size fan can provide a larger air volume, thereby improving the heat dissipation performance and improving the heat dissipation effect. Optionally, the first housing 120 of the working part 100 and the second housing 210 of the operating part 200 are detachably connected.

[0047] In some embodiments, reference Figure 2 and Figure 4 The operation part 200 further includes: a partition 220, which is located in the second shell 210 and divides the second shell 210 into two chambers S; the main control circuit board 300 is arranged in one of the two chambers S, and the heat dissipation fan 400 is arranged in the other of the two chambers S. In this embodiment, the partition 220 is located on one side of the central axis Z of the second shell 210 and is spaced from the central axis Z of the second shell 210, and the extension direction of the partition 220 is parallel to the central axis Z direction of the second shell 210. The partition 220 divides the internal space of the second shell 210 into two chambers S, and both chambers S are used to install components or devices of the light therapy beauty device. Among them, the volumes of the two chambers S are different, one chamber S has a large volume, and the other chamber S has a small volume. Among them, the main control circuit board 300 and the heat dissipation fan 400 are separately arranged in two chambers S. Specifically, the main control circuit board 300 is arranged in a chamber S with a relatively small volume, and the heat dissipation fan 400 is arranged in a chamber S with a relatively large volume. That is, the heat dissipation fan 400 can use a larger fan, and the output air volume of the heat dissipation fan 400 can be increased by selecting a large-sized fan.

[0048] In some embodiments, reference Figure 2 and Figure 4, the second shell 210 includes a first half shell 211, a middle frame 213, and a second half shell 212 that are connected in sequence, and the partition 220 is located on the inner side of the middle frame 213 and is integrally formed with the middle frame 213 or is detachably connected. In this embodiment, the second shell 210 includes a first half shell 211, a middle frame 213, and a second half shell 212. The first half shell 211 and the second half shell 212 are respectively located on opposite sides of the middle frame 213 and are detachably connected with the middle frame 213. The detachable connection method includes a snap connection, a screw connection, etc. Among them, the appearance structure, structural size, etc. of the first half shell 211 and the second half shell 212 can be the same or different, and can be set according to actual conditions. The inner side of the middle frame 213 is enclosed to form a receiving area, and the partition 220 is located in the receiving area and is set on the middle frame 213. The partition 220 can be integrally formed with the middle frame 213, or can be detachably connected with the middle frame 213. The detachable connection method includes a snap connection, a screw connection, etc., which is set according to actual conditions. The second shell 210 is connected to the middle frame 213 by docking the first half shell 211, and is connected to the middle frame 213 by docking the second half shell 212, so as to achieve assembly. Among them, one of the two chambers S is located on the side of the partition 220 facing the first half shell 211, and the other is located on the side of the partition 220 facing the second half shell 212. When it is necessary to inspect or repair the components or devices in either of the two chambers S, it is only necessary to remove the half shell (such as the first half shell 211 or the second half shell 212) corresponding to the chamber S from the middle frame 213, without the need to disassemble the second shell 210 as a whole, which is simple to operate and convenient to use.

[0049] In some embodiments, reference Figure 4 , the main control circuit board 300 is installed on one side of the partition 220, and the heat dissipation fan 400 is installed on the other side of the partition 220. In this embodiment, the partition 220 can be used as a mounting plate to install the main control circuit board 300 and the heat dissipation fan 400, and the main control circuit board 300 and the heat dissipation fan 400 are respectively installed on two opposite sides of the partition 220. Among them, the main control circuit board 300 and the heat dissipation fan 400 can be detachably installed on the partition 220, and the connection method can include screw connection, etc., which is set according to actual conditions. In addition to the main control circuit board 300 and the heat dissipation fan 400, the partition 220 can also be installed with other components or devices, but is not limited to this. In the operating part 200, the main control circuit board 300 and the heat dissipation fan 400 are installed on the partition 220, which is convenient for disassembly and assembly.

[0050] In some embodiments, reference Figure 2 , Figures 4 to 7, a windshield 221 is provided at one end of the partition 220 facing the light emitting assembly 110, and the windshield 221 protrudes from both sides of the partition 220, and the windshield 221 is provided with a first vent 1A connected to the air outlet of the heat dissipation fan 400. In this embodiment, a connection port 200A is configured on the operating part 200, and the working part 100 is partially embedded in the operating part 200 from the connection port 200A of the operating part 200 to be connected with the operating part 200. An installation cavity K is provided in the working part 100, and the part where the working part 100 is embedded in the operating part 200 is provided with an opening of the installation cavity K. The windshield 221 is connected and assembled with the working part 100 at the opening of the installation cavity K to cover the opening of the installation cavity K. Among them, the first vent 1A is set through the windshield 221, and the air outlet of the heat dissipation fan 400 is connected to the first vent 1A on the windshield 221, and then connected to the internal space of the working part 100. When the heat dissipation fan 400 is working, the heat dissipation fan 400 transmits gas between the first vent 1A and the internal space of the working part 100 to accelerate the gas flow in the internal space of the working part 100, thereby dissipating heat for the light-emitting component 110 and the like in the working part 100. Specifically, when the heat dissipation fan 400 adopts a blowing fan, the air outlet of the heat dissipation fan 400 outputs gas, and the output gas flows to the internal space of the working part 100 through the first vent 1A; and when the heat dissipation fan 400 adopts an exhaust fan, the air outlet of the heat dissipation fan 400 inhales gas, and the gas in the internal space of the working part 100 flows to the air outlet of the heat dissipation fan 400 through the first vent 1A. It is easy to understand that the wind shield 221 blocks the gas in the internal space of the working part 100 to prevent the gas from flowing out from the opening, so that the gas keeps flowing along the heat dissipation path.

[0051] In some embodiments, reference Figure 6 and Figure 7, the windshield 221 is also provided with a second vent 2A spaced apart from the first vent 1A, and a third vent 3A connected to the external environment is provided on one side of the second shell 210, and the third vent 3A is connected to the second vent 2A. In this embodiment, the second vent 2A is provided through the windshield 221 and is connected to the third vent 3A on the second shell 210, and the internal space of the working part 100 is connected to the second vent 2A on the windshield 221, and then connected to the third vent 3A on the second shell 210 of the operating part 200 to connect to the external environment. When the heat dissipation fan 400 is working, the working part 100 transmits gas to the external environment through the second vent 2A and the third vent 3A to accelerate the gas flow in the internal space of the working part 100, thereby dissipating the heat of the light-emitting component 110 and the like in the working part 100. Specifically, when the heat dissipation fan 400 adopts a blowing fan, the gas in the internal space of the working part 100 flows to the third vent 3A through the second vent 2A, and flows out to the external environment through the third vent 3A; and when the heat dissipation fan 400 adopts an exhaust fan, the gas in the external environment enters from the third vent 3A and flows to the second vent 2A, and flows into the internal space of the working part 100 through the second vent 2A. That is, the air outlet of the heat dissipation fan 400, the first vent 1A, the internal space of the working part 100, the second vent 2A, the third vent 3A and the external environment are connected in sequence to form a heat dissipation path. When the heat dissipation fan 400 is working, the gas flows along the heat dissipation path to dissipate the heat of the light-emitting component 110 and the like in the working part 100.

[0052] Optionally, there is a gap 1C between the first shell 120 and the second shell 210, and the heat dissipation fan 400 is connected to the external environment through the gap 1C. In this embodiment, when the first shell 120 is partially accommodated in the connection port of the second shell 210, the outer wall of the first shell 120 does not contact the inner edge of the connection port to form a gap 1C. The heat dissipation fan 400 is connected to the external environment through the gap 1C, that is, the gap 1C between the outer wall of the first shell 120 and the inner edge of the connection port can correspond to the first air duct used by the heat dissipation fan 400 to exchange gas with the external environment. Depending on the type of the heat dissipation fan 400 (the heat dissipation fan 400 can be a blowing fan or an exhaust fan), the external gas can flow to the heat dissipation fan 400 through the first air duct, or the gas discharged by the heat dissipation fan 400 can flow to the external environment through the first air duct.

[0053] In some embodiments, reference Figure 6 A second air duct T1 is provided between the second air vent 2A and the first air vent 1A to connect the two, and the light emitting assembly 110 is at least partially located in the second air duct T1; and / or,

[0054] A third air duct T2 is provided between the third vent 3A and the second vent 2A to connect the two.

[0055] In this embodiment, optionally, a second air duct T1 is provided between the second air vent 2A and the first air vent 1A to connect the two, the second air duct T1 is in the working part 100, and the light-emitting component 110 is at least partially located in the second air duct T1. That is, the first air vent 1A is connected to the second air vent 2A through the second air duct T1, thereby realizing gas transmission between the second air vent 2A. Depending on the type of the heat dissipation fan 400 provided (the heat dissipation fan 400 can be a blowing fan or an exhaust fan), when the heat dissipation fan 400 is working, the gas at the first air vent 1A can flow to the second air vent 2A through the second air duct T1, or the gas at the second air vent 2A can flow to the first air vent 1A through the second air duct T1. The gas flows along the second air duct T1, and can take away the heat in the second air duct T1, so as to dissipate the heat of at least part of the light-emitting component 110 accommodated in the second air duct T1.

[0056] Optionally, a third air duct T2 is provided between the third vent 3A and the second vent 2A to connect the two, and the third air duct T2 is located in the operating part 200. That is, the second vent 2A is connected to the third vent 3A through the third air duct T2, thereby realizing gas transmission between the third vent 3A. Depending on the type of the heat dissipation fan 400 (the heat dissipation fan 400 can be a blowing fan or an exhaust fan), when the heat dissipation fan 400 is working, the gas at the second vent 2A can flow to the third vent 3A through the third air duct T2, or the gas at the third vent 3A can flow to the second vent 2A through the third air duct T2.

[0057] In some embodiments, reference Figure 7 The windshield 221 is also provided with a wiring hole 1B, through which the connection wires between the main control circuit board 300 and the light-emitting component 110 pass. The wiring hole 1B is set through the windshield 221, and the hole shape and size of the wiring hole 1B can be set according to actual conditions, and are not limited here. The main control circuit board 300 in the operating part 200 is connected to the light-emitting component 110 in the working part 100 by passing the connection wire through the wiring hole 1B, and the wiring is convenient and easy to set.

[0058] In some embodiments, reference Figure 7 , the wiring hole 1B is located between the first vent 1A and the second vent 2A. In this embodiment, by setting the wiring hole 1B between the first vent 1A and the second vent 2A, a shorter wiring distance can be provided between the main control circuit board 300 and the light emitting component 110, which helps to reduce signal interference and improve the stability of signal transmission.

[0059] In some embodiments, reference Figure 4 , Figure 6 and Figure 8 The light-emitting assembly 110 includes: a light-emitting element 111 and a heat sink 112. A heat sink 112 is provided on one side of the heat sink 112 close to the windshield 221, and a receiving groove for receiving the light-emitting element 111 is provided on the other side of the heat sink 112 away from the windshield 221. In this embodiment, the light-emitting element 111 is used to emit light. The light-emitting element 111 may be a lamp tube, which may be a halogen lamp tube, a xenon lamp tube, etc. The heat sink 112 is used to dissipate heat for the light-emitting element 111. The heat sink 112 may be a heat sink arranged in an arc shape, and has an outer shape structure with one side concave and the other side convex. The convex side of the heat sink 112 is close to the windshield 221 and is provided with heat sink fins 1121. The heat sink fins 1121 are integrally formed with the heat sink 112 or are detachably connected. The concave side of the heat sink 112 is away from the windshield 221, and a corresponding receiving groove is formed. The light-emitting element 111 is received in the receiving groove. Specifically, when the light-emitting element 111 emits light, the heat sink 112 absorbs the heat emitted by the light-emitting element 111, transfers the heat to the heat sink fins 1121, and then further emits the heat to the space environment through the heat sink fins 1121. Furthermore, the air outlet of the heat dissipation fan 400 is connected to the space where the heat sink 112 and the heat sink fins 1121 are located. When the heat dissipation fan 400 is working, the gas in the space where the heat sink 112 and the heat sink fins 1121 are located can flow quickly to take away the heat of the heat sink 112, the heat sink fins 1121 and the space where the two are located, thereby achieving rapid heat dissipation. Among them, a plurality of heat sink fins 1121 can be provided, and the plurality of heat sink fins 1121 are arranged in sequence at intervals along the arc direction of the heat sink 112, and each heat sink fin 1121 is extended along the gas flow direction. Optionally, the heat sink 112 and the heat sink fins 1121 are made of metal (such as aluminum).

[0060] In some embodiments, reference Figure 4 and Figure 8 The light emitting assembly 110 further includes: a reflector 113, which is located on the other side of the heat sink 112 away from the windshield 221 and is in contact with the inner wall of the receiving groove. In this embodiment, the reflector 113 is used to reflect the light emitted by the light emitting element 111 projected thereon toward the light emitting position of the working part 100. The reflector 113 can be a reflector, which is arranged in an arc shape, adapted to the inner wall of the receiving groove, and one side of the reflector facing the inner wall of the receiving groove is correspondingly in contact with the inner wall of the receiving groove, and the other side of the reflector facing away from the inner wall of the receiving groove is formed as a reflective surface for reflecting the light emitted by the light emitting element 111. When light is projected onto the reflector 113, it will transfer heat to it, and the heat sink 112 can quickly absorb the heat on the reflector 113 to achieve heat dissipation of the reflector 113.

[0061] In some embodiments, reference Figure 1 , Figure 4 and Figure 6 The working part 100 is provided with a light outlet 110A, and the light emitting member 111 is arranged opposite to the light outlet 110A;

[0062] The light-emitting component 110 also includes: a light-transmitting component 114 and a light filter 115, wherein the light-transmitting component 114 is installed at the light outlet 110A; the light filter 115 is located between the light-emitting component 111 and the light outlet 110A, and a first gas flow channel Q1 is formed on one side of the light-emitting component 111 of the light filter 115, and a second gas flow channel Q2 is formed between the light filter 115 and the light-transmitting component 114.

[0063] In the present embodiment, when the light emitting element 111 emits light, the light emitted by it can pass through the light outlet 110A and be emitted to the outside of the working part 100. The shape and size of the light outlet 110A can be set according to actual conditions. Optionally, the light outlet 110A is a rectangular light outlet 110A. Among them, the light-transmitting element 114 is adapted to the light outlet 110A and is installed at the light outlet 110A of the working part 100 for light to pass through. The light-transmitting element 114 can be detachably arranged on the working part 100, and the arrangement method includes snap-on arrangement, etc., which is not limited. Exemplarily, the light-transmitting element 114 can be made of sapphire material, which has excellent light transmittance and durability. The filter element 115 can be a filter plate or a filter, which is used to filter the light emitted by the light emitting element 111 to obtain an outgoing light of a specific wavelength, such as the near-infrared light mentioned in the above embodiment. Among them, a first gas flow channel Q1 is formed on one side of the filter 115 toward the light-emitting element 111, and a second gas flow channel Q2 is formed between the filter 115 and the light-transmitting element 114. When the gas in the first gas flow channel Q1 flows, it can take away the heat of the light-emitting element 111 and the filter 115 on the side facing the light-emitting element 111; when the gas in the second gas flow channel Q2 flows, it can take away the heat of the light-transmitting element 114 and the filter 115 on the side facing the light-transmitting element 114 to achieve heat dissipation. Optionally, the air outlet of the heat dissipation fan 400 is connected to the first gas flow channel Q1 and the second gas flow channel Q2 respectively. When the heat dissipation fan 400 is working, it can accelerate the flow of gas in the first gas flow channel Q1 and the second gas flow channel Q2 to achieve heat dissipation of components such as the light-emitting element 111, the filter 115 and the light-transmitting element 114. The heat dissipation design of the dual gas flow channels can improve the heat dissipation effect of the light-emitting component 110 as a whole, thereby preventing components such as the light-transmitting element 114 from overheating and affecting the working performance of the light therapy beauty device.
