[0035] Based on the technical problem that the phototherapy beauty device in the prior art is too large in size and not compact enough in structure, which makes it inconvenient to store and carry, the embodiment of the utility model proposes a phototherapy beauty device, which has a reduced size, a compact structure, is convenient to store and carry, and can improve the user experience. Optionally, the phototherapy beauty device can be a milk light beauty device, including but not limited to this.

[0036] Reference Figures 1 to 3 , the light therapy beauty device includes:

[0037] A first housing 111, wherein a mounting cavity K is configured inside the first housing 111, wherein a light emitting assembly 130 is mounted in the mounting cavity K, and the first housing 111 is further configured with a light outlet 110A, wherein the light emitting assembly 130 is used to emit light, and the light is emitted through the light outlet 110A;

[0038] The second shell 112 is detachably connected to the first shell 111, and one end of the second shell 112 connected to the first shell 111 has a connecting port 112A, and the first shell 111 is partially accommodated in the connecting port 112A. A main control circuit board 120 and a heat dissipation fan 142 are arranged in the second shell 112. The main control circuit board 120 is electrically connected to the light-emitting component 130 and the heat dissipation fan 142 respectively. The heat dissipation fan 142 is connected to the installation cavity K to accelerate the gas flow in the installation cavity K to dissipate heat to the light-emitting component 130.

[0039] The phototherapy beauty device may at least have a working part and an operating part, and the working part and the operating part are detachably connected. Optionally, the first housing 111 and its internal components may constitute the working part of the phototherapy beauty device, and the working part is mainly used as a beauty head of the phototherapy beauty device, which is used to fit or approach human skin during the phototherapy process to perform phototherapy skin care on the human body. The second housing 112 and its internal components may constitute the operating part of the phototherapy beauty device, and the user may control the phototherapy beauty device to perform skin care operations by holding the operating part.

[0040] The shape of the first shell 111 can be a regular shape (column, table, cone, sphere, etc.) or a special shape, which can be set according to actual conditions. The first shell 111 is provided with a mounting cavity K inside, and the mounting cavity K is used to install devices such as the light emitting component 130, including but not limited to these. The surface of the first shell 111 is provided with a light outlet 110A, and the shape and size of the light outlet 110A can be set according to actual conditions, and optionally, as Figure 1 As shown, the light outlet 110A is a rectangular light outlet 110A. Optionally, a phototherapy surface G (which can be a plane, a curved surface, etc.) is constructed on the first shell 111, and the light outlet 110A is located on the phototherapy surface G. When the phototherapy beauty device is used for skin care, the phototherapy surface G on the first shell 111 is attached to or close to human skin.

[0041] The light-emitting component 130, as the light source of the phototherapy beauty instrument, can be arranged in the first shell 111 toward the light outlet 110A. When the light-emitting component 130 emits light, the light emitted by it can pass through the light outlet 110A and be emitted to the outside of the first shell 111. Among them, the structural composition of the light-emitting component 130 can be in various forms. For example, the light-emitting component 130 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 130 is filtered by the filter component, and various bands of care light can be output. The appropriate filter component can be selected according to the needs. For example, red light can promote the repair of skin collagen fibrous protein, blue light can treat acne and superficial fungal infections, green light can stimulate the regeneration of skin collagen and play a role in wrinkle removal, and near-infrared light can penetrate the deep layer of the skin and reach the shallow to middle layers of the dermis, effectively heating the water molecules in the dermis, stimulating collagen proliferation and reorganization, so that the skin becomes firm, smooth and elastic.

[0042] The shape of the second shell 112 can be a regular shape (cylinder, table, cone, sphere, etc.) or a special shape, which can be set according to actual conditions. Optionally, the shell shape of the second shell 112 is different from that of the first shell 111. Figure 2 and Figure 3As shown, one end of the second shell 112 used for connecting with the first shell 111 is formed with a connection port 112A adapted to the first shell 111, and the first shell 111 is partially embedded in the second shell 112 from the connection port 112A of the second shell 112 to connect with the second shell 112. That is, a part of the first shell 111 is hidden in the connection port 112A of the second shell 112, and the other part is exposed. Among them, the detachable connection between the first shell 111 and the second shell 112 can include screw connection, snap connection, etc., which are set according to actual conditions.

[0043] The main control circuit board 120 and the heat dissipation fan 142 are arranged in the second housing 112. The main control circuit board 120 is used to send control signals to the working devices of the phototherapy beauty device (such as the heat dissipation fan 142, the light-emitting component 130, etc.) and receive feedback status data, etc., including but not limited to this. The heat dissipation fan 142 is used to air-cool the components or devices (such as the light-emitting component 130) in the phototherapy beauty device. Specifically, the heat dissipation fan 142 is connected to the installation cavity K to accelerate the flow of gas in the installation cavity K. When the heat dissipation fan 142 is working, the gas in the installation cavity K can flow quickly to take away the heat of the light-emitting component 130 and the heat dissipated in the installation cavity K. Among them, the heat dissipation fan 142 can be a blowing fan or an exhaust fan, which can be set according to actual conditions.

[0044] The phototherapy beauty device of the present invention adopts a split shell, wherein the first shell 111 is partially accommodated in the connecting port 112A of the second shell 112, thereby reducing the external volume. At the same time, the components of the light emitting and heat dissipating structures are correspondingly arranged in the first shell 111 and the second shell 112, so that the structure is compact, convenient for storage and carrying, and can enhance the user experience.

[0045] In some embodiments, reference Figure 4 and Figure 5 The light-emitting component 130 includes: a light-emitting component 131 and a filter component 132. The light-emitting component 131 is arranged opposite to the light outlet 110A; the filter component 132 is located between the light-emitting component 131 and the light outlet 110A. In this embodiment, the light-emitting component 131 can be a lamp tube. In actual setting, the lamp tube is arranged relative to the light outlet 110A, and the plane where the lamp tube is located is parallel to the plane where the light outlet 110A is located. Furthermore, the lamp tube can be a halogen lamp tube, a xenon lamp tube, etc. Optionally, the light-emitting component 131 is mounted in the first shell 111. The filter component 132 can be a filter plate or a filter, which is used to filter the light emitted by the light-emitting component 131 to obtain light of a specific wavelength.

[0046] The light emitting assembly 130 further includes:

[0047] The reflective member 133 is disposed on a side of the light emitting member 131 away from the light outlet 110A to reflect the light projected thereon toward the light outlet 110A; and / or the light transmitting member 134 is installed at the light outlet 110A.

[0048] In this embodiment, optionally, the light emitting assembly 130 further includes a reflector 133, which is used to reflect the light emitted by the light emitting element 131 projected thereon toward the light outlet 110A. The reflector 133 may be a reflector, which is arranged in an arc shape, and a side of the reflector facing the light emitting element 131 is formed as a reflective surface for reflecting the light emitted by the light emitting element 131.

[0049] Optionally, the light emitting assembly 130 further includes a light-transmitting member 134, wherein the light-transmitting member 134 is adapted to the light outlet 110A and is installed at the light outlet 110A for light to pass through. The light-transmitting member 134 is detachably arranged on the first housing 111, and the arrangement method includes a snap-on arrangement, etc., which is not limited. Exemplarily, the light-transmitting member 134 can be made of sapphire material, which has excellent light transmittance and durability.

[0050] In some embodiments, reference Figures 1 to 3 The phototherapy beauty device also includes a heat sink 141, one side of the heat sink 141 faces the light-emitting component 130, and the other side is provided with heat dissipation fins 1411. The side of the heat sink 141 facing the light-emitting component 130 is concavely provided with a receiving groove, and the light-emitting component 131 is received in the receiving groove, and the side of the reflector 133 facing away from the light-emitting component 131 is in contact with the inner wall of the receiving groove.

[0051] Specifically, the heat sink 141 is used to dissipate heat for the light-emitting element. The heat sink 141 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. A receiving groove is formed on the concave side of the heat sink 141, and the light-emitting element 131 is received in the receiving groove. The reflector 133 is adapted to the inner wall of the receiving groove, and the side of the reflector 133 facing the inner wall of the receiving groove is correspondingly attached to the inner wall of the receiving groove. When light is projected onto the reflector 133, heat is transferred to it. The heat sink 141 can quickly absorb the heat on the reflector 133 to achieve heat dissipation of the reflector 133, so as to quickly absorb the heat emitted by the light-emitting element 131. A heat sink fin 1411 is arranged on the other side of the convex side of the heat sink 141. In this embodiment, a plurality of heat sink fins 1411 are arranged in sequence and spaced along the arc direction of the heat sink 141, and each heat sink fin 1411 is extended along the gas flow direction. The heat sink 1411 is integrally formed with the heat sink 141 or is detachably connected. When the light-emitting component 130 emits light, the heat sink 141 absorbs the heat emitted by the light-emitting component 130 and transfers it to the heat sink 1411, which is then further emitted to the installation cavity K through the heat sink 1411. It is understandable that a plurality of heat sink fins 1411 can be provided, and the specific number can be set according to actual conditions, and there is no limitation on this. Optionally, the heat sink 141 and the heat sink 1411 are made of metal (such as aluminum).

[0052] In some embodiments, reference Figure 2 , Figure 3 and Figure 5, a partition 150 is arranged in the second shell 112, and the partition 150 divides the second shell 112 into two chambers S; the main control circuit board 120 is arranged in one of the two chambers S, and the heat dissipation fan 142 is arranged in the other of the two chambers S. In this embodiment, the partition 150 divides the internal space of the shell into two chambers S, and the two chambers S are used to install components or devices of the beauty instrument. Among them, the main control circuit board 120 and the heat dissipation fan 142 are separately arranged in the two chambers S. Optionally, the second shell 112 includes a first half shell 1121, a middle frame 1123 and a second half shell 1122 which are connected in sequence, and the partition 150 is located on the inner side of the middle frame 1123 and is integrally formed with the middle frame 1123 or detachably connected. Specifically, the second shell 112 includes a first half shell 1121, a middle frame 1123 and a second half shell 1122. The first half shell 1121 and the second half shell 1122 are respectively located on opposite sides of the middle frame 1123 and are detachably connected to the middle frame 1123. The detachable connection method includes a snap connection, a screw connection, etc. Among them, the appearance structure, structural dimensions, etc. of the first half shell 1121 and the second half shell 1122 can be the same or different, and can be set according to actual conditions. The inner side of the middle frame 1123 is enclosed to form a receiving area, and the partition 150 is located in the receiving area and is set on the middle frame 1123. The partition 150 can be integrally formed with the middle frame 1123, or it can be detachably connected to the middle frame 1123. The detachable connection method includes a snap connection, a screw connection, etc., which can be set according to actual conditions. The second shell 112 is connected to the middle frame 1123 by docking the first half shell 1121, and connected to the middle frame 1123 by docking the second half shell 1122, so as to achieve assembly. Among them, one of the two chambers S is located on the side of the partition 150 facing the first half shell 1121, and the other is located on the side of the partition 150 facing the second half shell 1122. 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 1121 or the second half shell 1122) corresponding to the chamber S from the middle frame 1123, without the need to disassemble the second shell 112 as a whole, which is simple to operate and convenient to use.

[0053] In some embodiments, reference Figure 5 , the volume of one of the two chambers S is larger than the volume of the other, the main control circuit board 120 is located in the chamber S with a relatively smaller volume, and the heat dissipation fan 142 is located in the chamber S with a relatively smaller volume; and / or,

[0054] The main control circuit board 120 is installed on one side of the partition 150 , and the heat dissipation fan 142 is installed on the other side of the partition 150 .

[0055] In this embodiment, 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. The main control circuit board 120 is disposed in the chamber S with a relatively small volume, and the heat dissipation fan 142 is disposed in the chamber S with a relatively large volume. That is, the heat dissipation fan 142 can use a larger fan, and the output air volume of the heat dissipation fan 142 can be increased by using a large fan. Figure 3 and Figure 5 As shown, the heat dissipation fan 142 is at least located in the middle space of the second housing 112 and passes through the central axis Z of the housing. That is, the internal space of the second housing 112 is divided into most (such as 3 / 5 space, 2 / 3 space) for arranging the heat dissipation fan 142, and the heat dissipation fan 142 is installed in the main middle space position of the internal space of the second housing 112 and passes through the central axis Z of the second housing 112. Further, as Figure 5 As shown, the partition 150 is located on one side of the central axis Z of the second shell 112 and is spaced apart from the central axis Z of the second shell 112. The extension direction of the partition 150 is parallel to the central axis Z of the second shell 112, so that the two chambers S separated by the second shell 112 are large and small and have different volumes.

[0056] Optionally, the partition 150 can be used as a mounting plate to mount the main control circuit board 120 and the heat dissipation fan 142, and the main control circuit board 120 and the heat dissipation fan 142 are respectively mounted on two opposite sides of the partition 150. Among them, the main control circuit board 120 and the heat dissipation fan 142 can be detachably mounted on the partition 150, and the connection method can include screw connection, etc., which is set according to actual conditions. In addition to the main control circuit board 120 and the heat dissipation fan 142, the partition 150 can also be installed with other components or devices, but is not limited to this. In the second shell 112, the main control circuit board 120 and the heat dissipation fan 142 are installed on the partition 150, which is convenient for disassembly and assembly.

[0057] In some embodiments, reference Figure 3 , Figures 5 to 7 The portion of the first housing 111 accommodated in the connection port 112A is provided with an opening of the installation cavity K, one end of the partition 150 faces the opening of the installation cavity K and is provided with a windshield 151, and the windshield 151 protrudes relative to both sides of the partition 150;

[0058] The wind shield 151 covers the opening of the installation cavity K. A first vent 1A is provided on the wind shield 151. The air outlet of the heat dissipation fan 142 is connected to the installation cavity K through the first vent 1A.

[0059] In this embodiment, the first housing 111 is configured with an opening of the installation cavity K, and the opening is located at the portion of the first housing 111 for embedding the connection port 112A. When the first housing 111 is partially accommodated in the connection port 112A of the second housing 112 to be connected with the second housing 112, the windshield 151 in the second housing 112 is docked and assembled with the first housing 111 at the opening of the installation cavity K to cover the opening of the installation cavity K. It is easy to understand that the windshield 151 forms a barrier to the gas in the installation cavity K to prevent the gas from flowing out of the opening, so that the gas keeps flowing along the heat dissipation path.

[0060] Among them, the first vent 1A is set through the wind shield 151, and the air outlet of the heat dissipation fan 142 is connected with the first vent 1A on the wind shield 151, and then connected with the installation cavity K of the first shell 111. When the heat dissipation fan 142 is working, the heat dissipation fan 142 transmits gas between the first vent 1A and the installation cavity K to accelerate the gas flow in the installation cavity K, thereby dissipating the heat of the light-emitting components in the installation cavity K. Specifically, when the heat dissipation fan 142 adopts a blowing fan, the air outlet of the heat dissipation fan 142 outputs gas, and the output gas flows to the installation cavity K through the first vent 1A; when the heat dissipation fan 142 adopts an exhaust fan, the air outlet of the heat dissipation fan 142 inhales gas, and the gas in the installation cavity K flows to the air outlet of the heat dissipation fan 142 through the first vent 1A. The first vent 1A can be set one or more, and it can be set according to actual conditions.

[0061] Optionally, the first housing 111 is provided with a wind shield 113 located in the installation cavity K. The wind shield 113 is an annular housing, which surrounds at least part of the light-emitting assembly 130 and the heat sink 141. The wind shield 113 has a heat-insulating effect in the installation cavity K to reduce the heat transferred from the installation cavity K to the first housing 111, thereby avoiding the first housing 111 from being overheated and reducing the risk of burns during the use of the phototherapy beauty device. Optionally, the wind shield 113 can be made of a heat-insulating material.

[0062] In some embodiments, reference Figure 3 and Figure 7, the windshield 151 is also provided with a second vent 2A, the first vent 1A and the second vent 2A are spaced apart, the second shell 112 is provided with a third vent 3A connected to the external environment, and the installation cavity K is connected to the third vent 3A through the second vent 2A. In this embodiment, the second vent 2A is provided through the windshield 151 and is connected to the third vent 3A on the second shell 112, and the installation cavity K is connected to the external environment by communicating with the second vent 2A on the windshield 151, and then communicating with the third vent 3A on the second shell 112. When the heat dissipation fan 142 is working, the installation cavity K transmits gas to the external environment through the second vent 2A and the third vent 3A to accelerate the gas flow in the installation cavity K, thereby dissipating the heat of the light-emitting component 130 in the installation cavity K. Specifically, when the heat dissipation fan 142 adopts a blowing type fan, the gas in the installation cavity K 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 142 adopts an exhaust type fan, the gas in the external environment enters from the third vent 3A and flows to the second vent 2A, and flows into the installation cavity K through the second vent 2A. That is, the air outlet of the heat dissipation fan 142, the first vent 1A, the installation cavity K, 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 142 is working, the gas flows along the heat dissipation path to dissipate the heat of the light emitting component 130 and the like in the installation cavity K. The second vent 2A and the third vent 3A involved can be set at one or more, and can be set according to actual conditions.

[0063] In some embodiments, reference Figure 3 and Figure 7 , a fourth vent 4A connected to the external environment is provided on the first shell 111, and the installation cavity K is connected to the fourth vent 4A. In this embodiment, the installation cavity K is connected to the external environment by connecting to the fourth vent 4A on the first shell 111. When the heat dissipation fan 142 is working, gas is transmitted between the installation cavity K and the external environment through the fourth vent 4A to accelerate the flow of gas in the installation cavity K, thereby dissipating heat for the light-emitting component 130 and the like in the installation cavity K. Specifically, when the heat dissipation fan 142 adopts a blowing fan, the gas in the installation cavity K flows out to the external environment through the fourth vent 4A; and when the heat dissipation fan 142 adopts an exhaust fan, the gas in the external environment flows into the installation cavity K from the fourth vent 4A. That is, the air outlet of the heat dissipation fan 142, the first vent 1A, the installation cavity K, the fourth vent 4A and the external environment are sequentially connected to form a heat dissipation path. When the heat dissipation fan 142 is working, the gas flows along the heat dissipation path to dissipate the heat of the light-emitting component 130 and the like in the installation cavity K. The fourth vent 4A can be provided with one or more, and can be provided according to actual conditions.

[0064] In combination with the above embodiments, Figure 7 As shown, when the wind hood 113 is provided in the installation cavity K of the first shell 111, the wind hood 113 is correspondingly provided with a fifth vent 5A, and the fifth vent 5A corresponds to the fourth vent 4A. The gas in the installation cavity K flows to the fourth vent 4A through the fifth vent 5A, or the gas flowing in from the fourth vent 4A flows to the installation cavity K through the fifth vent 5A. Correspondingly, the fifth vent 5A can be provided with one or more, depending on the actual situation. By providing the fifth vent 5A at the position corresponding to the fourth vent 4A on the wind hood 113, it is possible to avoid the wind hood 113 from obstructing the flow of gas, shorten the gas flow distance, and improve the heat dissipation effect.

[0065] In some embodiments, reference Figure 5 and Figure 7 , there is a gap 1C between the first shell 111 and the second shell 112, and the heat dissipation fan 142 is connected to the external environment through the gap 1C. In this embodiment, when the first shell 111 is partially accommodated in the connection port 112A of the second shell 112, the outer wall of the first shell 111 does not contact the inner edge of the connection port 112A to form a gap 1C, that is, the gap 1C between the outer wall of the first shell 111 and the inner edge of the connection port 112A can correspond to a first air duct for gas flow. Optionally, the gap 1C is a circumferential gap 1C set along the edge of the connection port 112A. The heat dissipation fan 142 is in the internal space of the second shell 112 and is connected to the external environment through the gap 1C. When the heat dissipation fan 142 is working, the heat dissipation fan 142 transmits gas to the external environment through the gap 1C. Specifically, when the heat dissipation fan 142 adopts a blowing fan, the gas in the external environment enters the second housing 112 through the gap 1C and is sucked into the heat dissipation fan 142; and when the heat dissipation fan 142 adopts an exhaust fan, the gas exhausted by the heat dissipation fan 142 flows into the external environment through the gap 1C. That is, the external environment, the gap 1C, the air outlet of the heat dissipation fan 142, the first vent 1A, the installation cavity K, the fourth vent 4A and the external environment are sequentially connected to form a heat dissipation path. When the heat dissipation fan 142 is working, the gas flows along the heat dissipation path to dissipate the light emitting component 130 in the installation cavity K and the like.

[0066] In some embodiments, a shielding structure (not shown) is provided on the first shell 111 or the second shell 112, and the shielding structure is located between the fourth vent 4A and the gap 1C, and is used to prevent the airflow between the fourth vent 4A and the gap 1C from communicating. In this embodiment, on the first shell 111 or the second shell 112, the shielding structure can be integrally formed with the first shell 111 or the second shell 112, or can be detachably connected to the first shell 111 or the second shell 112, and can be provided according to actual conditions. Among them, the shielding structure can be a shielding plate, a shielding sheet, or a shielding cover, etc. The shielding structure blocks the airflow between the fourth vent 4A and the gap 1C, so that the airflow between the fourth vent 4A and the gap 1C is not interconnected. For example, when the heat dissipation fan 142 adopts a blowing fan, the shielding structure blocks the hot air discharged through the fourth vent 4A of the first shell 111 to guide it to the external environment, which can prevent the hot air from flowing into the heat dissipation fan 142 of the second shell 112 through the gap 1C again and causing heat flow circulation, thereby reducing the impact on the heat dissipation effect of the phototherapy beauty instrument and ensuring the heat dissipation performance; for another example, when the heat dissipation fan 142 adopts an exhaust fan, the shielding structure blocks the hot air discharged through the gap 1C to guide it to the external environment, thereby preventing the hot air from flowing into the installation cavity K of the first shell 111 through the fourth vent 4A again and causing heat flow circulation, thereby reducing the impact on the heat dissipation effect of the phototherapy beauty instrument and ensuring the heat dissipation performance.
