[0048] Based on the technical problem that existing light therapy beauty devices for skin care are prone to scalding users, the embodiment of the utility model proposes a light therapy beauty device to improve heat dissipation performance and reduce the risk of scalding users. Optionally, the light therapy beauty device can be a milk light beauty device, including but not limited to this.

[0049] Reference Figures 1 to 5 The phototherapy beauty device includes: a shell 110, a main control circuit board 120 and a light-emitting component 130, the shell 110 is provided with a light outlet 110A; the main control circuit board 120 is arranged in the shell 110; the light-emitting component 130 is arranged in the shell 110, and the light-emitting component 130 includes a light-emitting component 131, a filter component 132 and a light-transmitting component 134 arranged in sequence, the light-emitting component 131 is arranged opposite to the light outlet 110A and is electrically connected to the main control circuit board 120, the filter component 132 is located between the light-emitting component 131 and the light outlet 110A, the light-transmitting component 134 is arranged at the light outlet 110A, a first gas flow channel Q1 is formed on one side of the filter component 132 toward the light-emitting component 131, and a second gas flow channel Q2 is formed between the filter component 132 and the light-transmitting component 134.

[0050] The housing 110 may be in the form of a single housing structure or a multi-housing structure (i.e., multiple housings 110 are combined and arranged) according to actual conditions. The housing 110 is provided with a light outlet 110A for emitting light from the light emitting component 130. Figure 1 As shown, the shell 110 is constructed with a phototherapy surface G (the phototherapy surface can be a plane, a curved surface, etc.), 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 of the shell 110 is in contact with or close to the human skin.

[0051] The main control circuit board 120 and the light emitting component 130 are both arranged in the housing 110. The main control circuit board 120 is used to send control signals to the working components (such as the light emitting component 130, etc.) of the light therapy beauty device and receive feedback status data, etc., including but not limited to this. The light emitting component 130 serves as the light source of the light therapy beauty device. When the light emitting component 130 emits light, the light emitted by it can pass through the light outlet 110A and be emitted out of the housing 110. Among them, the light emitting component 130 mainly includes a light emitting part 131, a filter part 132 and a light transmitting part 134. The light emitting part 131 can be a lamp tube, such as a halogen lamp tube, a xenon lamp tube, etc. In actual setting, the light emitting part 131 is arranged relative to the light outlet 110A, and the plane where the light emitting part 131 is located is parallel to the plane where the light outlet 110A is located. The filter 132 is located between the light emitting element 131 and the light outlet 110A. The filter 132 can be a filter plate or a filter, which can filter the light emitted by the light emitting element 131 to obtain light of a specific wavelength. The light-transmitting element 134 is adapted to the light outlet 110A and is installed at the light outlet 110A for light to pass through. The light-transmitting element 134 is detachably arranged on the housing 110, and the arrangement method includes a snap-on arrangement, etc., which is not limited. Exemplarily, the light-transmitting element 134 can be made of sapphire material, which has excellent light transmittance and durability.

[0052] The light emitted by the light emitting element 131 is filtered by the light filter 132, and light of various wavelengths can be output. The appropriate light filter 132 can be selected according to the needs. The output light passes through the light-transmitting element 134 and is emitted from the light outlet 110A. Lights of different wavelengths have corresponding phototherapy effects. 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 the regeneration of skin collagen and play a role in wrinkle removal, and near-infrared light can penetrate deep into the skin, directly 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.

[0053] Furthermore, if Figure 3 and Figure 4As shown, the housing 110 has two gas flow channels for gas flow, namely the first gas flow channel Q1 and the second gas flow channel Q2. The first gas flow channel Q1 and the second gas flow channel Q2 are respectively located on opposite sides of the filter 132. Specifically, the first gas flow channel Q1 is formed on one side of the filter 132 toward the light-emitting component 131, and the light-emitting component 131 and the like are located in the first gas flow channel Q1. The second gas flow channel Q2 is formed on one side of the filter 132 toward the light-transmitting component 134, and the second gas flow channel Q2 is located between the filter 132 and the light-transmitting component 134. When the gas flows along the first gas flow channel Q1, it can take away the heat of the light-emitting component 131 and other components to achieve heat dissipation; and when the gas flows along the second gas flow channel Q2, it can take away the heat of the light-transmitting component 134 to achieve heat dissipation. Optionally, the phototherapy beauty device may include a heat dissipation device, which is connected to the first gas flow channel Q1 and the second gas flow channel Q2, and is used to accelerate the flow of gas in the first gas flow channel Q1 and the second gas flow channel Q2 by providing wind force.

[0054] Based on the above-mentioned dual gas flow channel heat dissipation structure design, it can be known that the beauty instrument of the present invention can not only dissipate heat for the light-emitting component 131, but also dissipate heat for the light-transmitting component 134, so as to prevent heat accumulation at positions such as the light-transmitting component 134 and cause local overheating, thereby reducing the risk of scalding the user.

[0055] In some embodiments, reference Figure 2 , Figure 3 , Figure 6 and Figure 7 The phototherapy beauty instrument also includes: a heat sink 141 and a heat dissipation fan 142. The heat sink 141 is arranged in the shell 110. One side of the heat sink 141 faces the light-emitting element 131, and the other side is provided with heat dissipation fins 1411; the heat dissipation fan 142 is arranged in the shell 110 and is electrically connected to the main control circuit board 120. The air outlet of the heat dissipation fan 142 is connected to the first gas flow channel Q1 and the second gas flow channel Q2.

[0056] In this embodiment, the phototherapy beauty instrument uses a heat dissipation fan 142 and a heat sink 141 for combined heat dissipation, wherein the heat sink 141 is arranged in the housing 110, specifically, it can be located in the first gas flow channel Q1, one side of the heat sink 141 faces the light-emitting element 131, and the other side is provided with heat dissipation fins 1411. The heat sink 141 can absorb the heat emitted by the light-emitting element 131 when it emits light, and transfer it to the heat dissipation fins 1411, and then dissipate it to the first gas flow channel Q1 through the heat dissipation fins 1411. Among them, the heat sink 141 can be a heat dissipation cover arranged in an arc shape, with 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 accommodated in the receiving groove, and the heat dissipation fins 1411 are located on the convex side of the heat sink 141. There may be multiple heat sink fins 1411, which are sequentially spaced along the arc direction of the heat sink 141, and each heat sink fin 1411 extends along the gas flow direction. Optionally, the heat sink 141 and the heat sink fins 1411 are made of metal (such as aluminum).

[0057] The heat dissipation fan 142 is disposed in the housing 110. The heat dissipation fan 142 is used to cool the components or devices (such as the light-emitting component 130) in the phototherapy beauty device. The heat dissipation fan 142 can be a blowing fan or an exhaust fan, which can be set according to actual conditions. Specifically, the air outlet of the heat dissipation fan 142 is connected to the first gas flow channel Q1 and the second gas flow channel Q2 respectively. When the heat dissipation fan 142 is working, the wind force provided by the heat dissipation fan 142 can accelerate the flow of gas in the first gas flow channel Q1 and the second gas flow channel Q2, so as to achieve rapid heat dissipation of components or devices such as the light-emitting component 131 and the light-transmitting component 134.

[0058] In some embodiments, reference Figures 2 to 5 The phototherapy beauty device further includes: a mounting frame 160, the mounting frame 160 is disposed in the housing 110, and two ends of the mounting frame 160 form a through open cavity 160A;

[0060] In this embodiment, the mounting frame 160 is arranged in the housing 110 corresponding to the light outlet 110A and is located between the light outlet 110A and the light emitting element 131. The two ends of the mounting frame 160 form a through open cavity 160A, one end of the open cavity 160A faces the light emitting element 131, and the other end of the open cavity 160A faces the light outlet 110A. The light emitted by the light emitting element 131 can pass through the open cavity 160A of the mounting frame 160 to reach the light outlet 110A. The shape of the mounting frame 160 can be set according to actual conditions. For example, the mounting frame 160 is a rectangular frame. The filter element 132 and the light-transmitting element 134 are respectively located at the two ends of the open cavity 160A, and the filter element 132 covers one end of the open cavity 160A. The second gas flow channel Q2 is located in the open cavity 160A. The gas inlet and gas outlet of the second gas flow channel Q2 are respectively constructed on the opposite sides of the mounting frame 160. The gas can flow into the second gas flow channel Q2 from the gas inlet on one side of the mounting frame 160, flow through the second gas flow channel Q2, and then flow out of the second gas flow channel Q2 from the gas outlet on the other side of the mounting frame 160.

[0061] In some embodiments, reference Figure 4 and Figure 5 A first gap is provided between one side of the mounting frame 160 and one side of the filter element 132 to form a gas inlet of the second gas flow channel Q2; a second gap is provided between the other side of the mounting frame 160 and the other side of the filter element 132 to form a gas outlet of the second gas flow channel Q2.

[0067] In some embodiments, reference Figures 1 to 3 The housing 110 includes a first housing 111 and a second housing 112 detachably connected to the first housing 111 . The first housing 111 is internally configured with a mounting cavity K, and a light outlet 110A is formed in the first housing 111 .

[0068] The light emitting assembly 130 and the heat sink 141 are disposed in the installation cavity K, and the first gas flow channel Q1 and the second gas flow channel Q2 are formed in the installation cavity K;

[0069] The main control circuit board 120 and the heat dissipation fan 142 are disposed in the second housing 112 .

[0070] The phototherapy beauty device may have at least a working part and an operating part, and the working part and the operating part are detachably connected. The first shell 111 and the second shell 112 included in the corresponding shell, optionally, the first shell 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 shell 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.

[0071] Among them, 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 an installation cavity K inside, and the installation cavity K is used to install devices such as the light-emitting component 130 and the heat sink 141, including but not limited to this. In addition, the first gas flow channel Q1 and the second gas flow channel Q2 are formed in the installation cavity K, and the gas is divided into at least two parts in the installation cavity K, and when the heat dissipation fan 142 is working, a part of the gas flows along the first gas flow channel Q1 in the first gas flow channel Q1, and the other part of the gas flows along the second gas flow channel Q2 in the second gas flow channel Q2.

The shape of the second shell 112 can be a regular shape (column, 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. The second housing 112 contains a main control circuit board 120 and a heat dissipation fan 142 , including but not limited to these.

[0072] Alternatively, if Figure 2 As 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 method between the first shell 111 and the second shell 112 can include screw connection, snap connection, etc., which is set according to actual conditions. The phototherapy beauty device adopts a split shell structural design, wherein the first shell 111 is partially accommodated in the connection port 112A of the second shell 112, which can reduce the external volume, have a compact structure, and is convenient for storage and carrying.

[0073] Alternatively, if Figure 3 As shown, 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.

Optionally, the wind shield 113 can be made of a heat-insulating material.

[0074] In some embodiments, reference Figure 2 , Figure 3 , Figures 7 to 9 The first shell 111 is provided with an opening of the mounting cavity K, and the second shell 112 is provided with a windshield plate 151;

It is easy to understand that the windshield 151 forms a barrier at the opening of the installation cavity K to prevent the gas from escaping from the opening, so that the gas keeps flowing along the heat dissipation path.

[0077] 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, that is, to dissipate 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 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.

[0078] In some embodiments, reference Figure 2 , Figure 3 , Figures 7 to 9 The windshield 151 is further 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 communicating with the external environment, and the installation cavity K is communicated with the third vent 3A through the second vent 2A; and / or,

[0079] The first shell 111 is provided with a fourth vent 4A communicating with the external environment, and the installation cavity K is communicated with the fourth vent 4A.

[0080] In this embodiment, optionally, the second vent 2A is provided through the windshield 151 and communicates with the third vent 3A on the second shell 112, and the installation cavity K communicates with the second vent 2A on the windshield 151, and then communicates with the third vent 3A on the second shell 112, so as to communicate with the external environment. When the heat dissipation fan 142 is working, the installation cavity K transmits gas with the external environment through the second vent 2A and the third vent 3A, so as 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 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 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 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 second vent 2A and the third vent 3A involved can be provided with one or more, and can be provided according to actual conditions.

[0081] Optionally, 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, the installation cavity K transmits gas to the external environment through the fourth vent 4A to accelerate the flow of gas 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 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 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 in the installation cavity K. The fourth vent 4A can be set at one or more, and can be set according to actual conditions.

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 of the hood 113 corresponding to the fourth vent 4A for ventilation, it is possible to avoid the hood 113 from obstructing the flow of gas, shorten the gas flow distance, and improve the heat dissipation effect.

[0086] When the cooling fan is a blowing fan, the gas inlet of the first gas flow channel Q1 and the gas inlet of the second gas flow channel Q2 are correspondingly located within the range of the first vent 1A, so that when the cooling fan is working, the gas passing through the first vent 1A can flow smoothly to the gas inlet of the first gas flow channel Q1 and the gas inlet of the second gas flow channel Q2, and then enter the first gas flow channel Q1 and the second gas flow channel Q2, which helps to improve the heat dissipation efficiency; the gas outlet of the first gas flow channel Q1 and the gas outlet of the second gas flow channel Q2 are correspondingly located within the range of the second vent 2A, so that when the cooling fan is working, the gas flowing out from the gas outlet of the first gas flow channel Q1 and the gas outlet of the second gas flow channel Q2 can flow smoothly to the second vent 2A, which helps to improve the heat dissipation efficiency.

[0087] When the heat dissipation fan is an exhaust fan, the gas inlet of the first gas flow channel Q1 and the gas inlet of the second gas flow channel Q2 are correspondingly located within the range of the second vent 2A, so that when the heat dissipation fan is working, the gas passing through the second vent 2A can smoothly flow to the gas inlet of the first gas flow channel Q1 and the gas inlet of the second gas flow channel Q2, and then enter the first gas flow channel Q1 and the second gas flow channel Q2, which helps to improve the heat dissipation efficiency; the gas outlet of the first gas flow channel Q1 and the gas outlet of the second gas flow channel Q2 are correspondingly located within the range of the first vent 1A. So that when the heat dissipation fan is working, the gas flowing out from the gas outlet of the first gas flow channel Q1 and the gas outlet of the second gas flow channel Q2 can smoothly flow to the first vent 1A, which helps to improve the heat dissipation efficiency.
