Description

Technical Field

[0001] This application relates to the field of beauty devices, and particularly to a laser beauty device. Background Art

[0002] A laser beauty device is an instrument that uses laser on the skin to achieve beauty effects, such as hair removal or skin rejuvenation.

[0003] Laser beauty devices are usually applied as large medical devices, which are not convenient for users.

[0004] In related technologies, the inventor miniaturized the laser beauty device to make it suitable for home use.

[0005] A large amount of heat is generated when emitting laser, and laser beauty devices are generally small and compact, making it difficult to solve the heat dissipation problem in a limited space. Summary of the Utility Model

[0006] This application provides a laser beauty device to improve the heat dissipation effect of the laser light source assembly.

[0007] An embodiment of this application provides a laser beauty device, which includes a housing, a laser light source assembly, a cold source assembly, a heat dissipation assembly, and a heat dissipation driving member. An accommodation cavity is formed inside the housing. One end of the housing has an exit port. The housing is provided with an air inlet and an air outlet, and both the air inlet and the air outlet communicate the accommodation cavity with the outside of the housing. The laser light source assembly is disposed in the accommodation cavity and is used to generate laser that exits from the exit port. The cold source assembly is disposed in the accommodation cavity and has a cold end and a hot end. The cold end is used to provide cold quantity to the skin at the exit port. The heat dissipation assembly includes a first heat dissipation member and a second heat dissipation member. The first heat dissipation member is thermally conductively connected to the laser light source assembly. The second heat dissipation member is thermally conductively connected to the hot end and is spaced apart from the first heat dissipation member. The heat dissipation driving member is disposed in the accommodation cavity and is used to generate an air flow that sequentially passes through the first heat dissipation member and the second heat dissipation member between the air inlet and the air outlet.

[0008] This laser beauty device can generate laser through a laser light source component. The laser irradiates the user's skin through the light outlet to achieve beauty treatment. Cold quantity is generated by a cold source component to apply cold compress to the skin irradiated by the laser. The first heat dissipation component and the second heat dissipation component dissipate heat from the laser light source component and the cold source component respectively. The air inlet and the air outlet communicate the accommodation cavity and the outside of the housing, enabling gas exchange between the accommodation cavity and the outside of the housing. The heat dissipation driving component drives the air flow, and the first heat dissipation component and the second heat dissipation component dissipate heat through the air flow in sequence, so that the air flow first passes through the first heat dissipation component to provide heat dissipation for the laser light source component with relatively high heat dissipation requirements, and then the air flow passes through the second heat dissipation component to provide heat dissipation for the cold source component with relatively low heat dissipation requirements. To ensure the heat dissipation of the laser light source component mainly and improve the overall heat dissipation effect of the laser beauty device. The first heat dissipation component and the second heat dissipation component are arranged at intervals, so that heat is not directly transferred between the first heat dissipation component and the second heat dissipation component. When the cold source component dissipates heat, the heat diffused to the first heat dissipation component by the second heat dissipation component is reduced, thereby reducing the influence of the second heat dissipation component on the heat dissipation effect of the first heat dissipation component. Cold quantity refers to the energy value of the heat consumed by the cold source component through refrigeration per unit time.

[0009] In a possible implementation manner, the laser generated by the laser light source component exits from the light outlet along the first direction. The housing has a first dimension along the first direction, a second dimension along the second direction, and a third dimension along the third direction. The first direction, the second direction, and the third direction are perpendicular to each other. The first dimension is greater than the second dimension and the third dimension, so that the housing forms a holding area extending along the first direction.

[0010] This laser beauty device is a portable laser beauty device that is roughly straight-bar shaped. The first dimension is greater than the second dimension and the third dimension, and the first direction forms the length direction of the laser beauty device. The laser of the laser light source component exits along the length direction, and the user holds it in the holding area extending along the length direction, which is convenient for the user to operate.

[0011] In a possible implementation manner, the air inlet and the air outlet are arranged at intervals along the first direction, and the first heat dissipation component and the second heat dissipation component are at least partially located between the air inlet and the air outlet. A holding area is formed between the air inlet and the air outlet.

[0012] In this laser beauty device, the holding area is located between the air inlet and the air outlet, reducing the influence of the user's hand on the air outlet and the air inlet when the user holds the housing.

[0013] In a possible implementation manner, in the third direction, the air outlet corresponds to the second heat dissipation component.

[0014] In this laser beauty device, the air outlet corresponds to the second heat dissipation component, so that the air flow can pass through the entire second heat dissipation component as much as possible, improving the heat dissipation effect of the second heat dissipation component.

[0015] In a possible implementation, the air inlet and the air outlet are arranged on the same side of the housing in the third direction.

[0016] In this laser beauty device, the air inlet and the air outlet are located on the same side, which can enable the air flow to basically circulate on the side of the accommodating cavity close to the air inlet and the air outlet, reducing the air flow path.

[0017] In a possible implementation, the air inlet is arranged in the air inlet area of the housing. Along the third direction, the size of the housing in the air inlet area is larger than the size of the housing in the holding area, and the heat dissipation driving component is arranged in the accommodating cavity of the air inlet area.

[0018] In this laser beauty device, the position of the housing at the air inlet can have a larger space, so as to accommodate a heat dissipation driving component with a larger size and higher power, improving the heat dissipation effect of the laser beauty device.

[0019] In a possible implementation, the housing includes a first half-shell and a second half-shell. The first half-shell and the second half-shell are detachably connected, and the accommodating cavity is formed between the first half-shell and the second half-shell.

[0020] In this laser beauty device, through the detachable connection of the first half-shell and the second half-shell, it is convenient to disassemble and assemble the cold source component and the laser light source component in the accommodating cavity.

[0021] In a possible implementation, the first heat dissipation component and the second heat dissipation component are arranged at intervals along the first direction.

[0022] In this laser beauty device, the arrangement direction of the first heat dissipation component and the second heat dissipation component matches the laser emission direction. The overall size of the laser beauty device in the direction perpendicular to the first direction is reduced, which is convenient for the user to hold the laser beauty device by hand. Especially when the first heat dissipation component includes a first heat dissipation part and a first heat dissipation fin, and the second heat dissipation component includes a second heat dissipation part and a second heat dissipation fin, the first heat dissipation fin and the second heat dissipation fin can be spaced apart in the first direction, restricting the heat conduction between the first heat dissipation fin and the second heat dissipation fin. And the first heat dissipation fin and the second heat dissipation fin have a larger size in the third direction, and the first heat dissipation fin and the second heat dissipation fin being spaced apart along the first direction can reduce the overall size of the laser beauty device in the direction perpendicular to the first direction. However, the first heat dissipation part in the first heat dissipation component and the second heat dissipation part in the second heat dissipation component can also be spaced apart in the second direction or the third direction.

[0023] In a possible implementation, the laser light source component and the cold source component are arranged at intervals along the first direction.

[0024] In this laser beauty instrument, the laser light source assembly and the cold source assembly are arranged at intervals along the first direction. In other words, the laser light source assembly and the cold source assembly are arranged at intervals along the length direction, thereby improving the space utilization rate of the accommodating cavity. The first heat sink and the second heat sink are spaced at intervals along the first direction, and the laser light source assembly and the cold source assembly are also spaced at intervals along the first direction, thereby facilitating the corresponding positions of the first heat sink, the second heat sink, the laser light source assembly and the cold source assembly.

[0025] In a possible implementation, the air inlet includes a plurality of air inlet holes, and the air outlet includes a plurality of air outlet holes. The air inlet holes communicate with the accommodating cavity and the outside of the shell, and the air outlet holes communicate with the accommodating cavity and the outside of the shell.

[0026] In this laser beauty instrument, multiple air inlet holes form an air inlet, and on the premise that the entire air inlet can provide airflow for the first heat sink and the second heat sink, the size of each air inlet hole is small, thereby shielding some large debris from entering the accommodating cavity, so as to protect the components in the accommodating cavity. Multiple air outlet holes form an air outlet, and on the premise that the entire air outlet can discharge the airflow in the accommodating cavity, the size of each air outlet hole is small, thereby shielding some large debris from entering the accommodating cavity, so as to protect the components in the accommodating cavity.

[0027] In a possible implementation, the air outlet hole is a waist-shaped hole, and the waist-shaped hole extends parallel to the second direction.

[0028] In this laser beauty instrument, the waist-shaped hole can correspond to multiple second heat dissipation sub-channels in the second heat dissipation element at the same time, so that the airflow flowing in the multiple second heat dissipation sub-channels can flow out of the accommodating cavity evenly. In a possible implementation, the heat dissipation drive element includes a heat dissipation fan, which is arranged on a side of the first heat dissipation element away from the second heat dissipation element, and the heat dissipation fan is used to introduce the airflow outside the accommodating cavity into the accommodating cavity.

[0029] In this laser beauty instrument, the cooling fan can make the gas in the housing flow to generate airflow. Moreover, the cooling fan is arranged on the side of the first heat sink away from the second heat sink. Combined with the aforementioned fluid passing through the first heat sink and the second heat sink in sequence, it can be known that the fluid will first pass through the cooling fan and then pass through the first heat sink and the second heat sink. Even if there is dust and other debris in the fluid, it will first adhere to the cooling fan, which can reduce the probability of debris adhering to the first heat sink and the second heat sink, and then extend the cleaning and maintenance cycle of the first heat sink and the second heat sink when cleaning and maintaining the laser beauty instrument.

[0030] In a possible implementation, the cooling fan is a centrifugal fan. The first half shell and the second half shell are detachably connected in a third direction, which is perpendicular to the first direction. The first half shell is provided with an air inlet and an air outlet, the air inlet and the air outlet are arranged at intervals in the first direction, and the first heat dissipation member and the second heat dissipation member are at least partially located between the air inlet and the air outlet.

[0031] In this laser beauty device, the cooling fan is set as a centrifugal fan, which can reduce the space occupied by the cooling fan in the accommodating cavity in the third direction. Both the air inlet and the air outlet are arranged on the first half shell, and the air duct in the whole accommodating cavity can also be arranged on the side close to the first half shell, and the relative positions of the air inlet and the air outlet are determined by the first half shell. This reduces the position tolerance of the air inlet and the air outlet caused by assembly in the case where the air inlet and the air outlet are respectively arranged on the first half shell and the second half shell.

[0032] In a possible implementation, the laser light source assembly includes a laser. The laser beauty device further includes an optical waveguide, the laser is used to emit laser light to the optical waveguide, and the optical waveguide is arranged between the light outlet and the laser to conduct the laser light. The first heat dissipation member is thermally conductively connected to the laser, or the first heat dissipation member is thermally conductively connected to the laser and the optical waveguide.

[0033] In this laser beauty device, the first heat dissipation member is mainly involved in the heat dissipation of the laser. A large amount of heat is generated when the laser emits laser light, and heat is also generated due to optical loss during the propagation in the optical waveguide. The heat dissipation requirement for this part of the heat is generally less than that of the laser.

[0034] In a possible implementation, the second heat dissipation member is located between the optical waveguide and the housing, and the first heat dissipation member is arranged between the laser and the housing. Along the third direction, the optical waveguide protrudes from the laser, and the first heat dissipation member and the second heat dissipation member are spaced apart along the third direction.

[0035] In this laser beauty device, the optical waveguide protrudes from the laser. This shape of the optical waveguide is beneficial to converging the laser, making the laser have more concentrated energy, but it is not easy to match the positions of the optical waveguide and the laser. By spacing the first heat dissipation member and the second heat dissipation member along the third direction, the position difference between the optical waveguide and the laser can be matched, and at the same time, the heat conduction between the first heat dissipation member and the second heat dissipation member can be reduced.

[0036] In a possible implementation, the laser light source assembly further includes a laser bracket, and the laser bracket is connected to the housing in the accommodating cavity. Both the laser and the first heat dissipation member are connected to the laser bracket.

[0037] In this laser beauty device, the laser beauty device fixes the laser and the first heat dissipation member through the laser bracket, improving the connection stability between the laser and the first heat dissipation member.

[0038] In a possible implementation, the laser beauty device further includes an optical waveguide bracket, which fixedly connects the optical waveguide member and the heat dissipation component.

[0039] In such a laser beauty device, there are various forms of fixing the optical waveguide member and the heat dissipation component through the optical waveguide bracket. The optical waveguide bracket can connect the optical waveguide member and the first heat dissipation member, connect the optical waveguide member and the second heat dissipation member, or connect the optical waveguide member, the first heat dissipation member and the second heat dissipation member. This improves the connection stability between the optical waveguide member and the heat dissipation component, and the optical waveguide bracket can also transfer heat between the optical waveguide member and the heat dissipation component, thereby realizing the heat dissipation of the optical waveguide member.

[0040] In a possible implementation, the laser includes a laser emitting member and a heat sink. The heat sink has two opposite sides, the laser emitting member is disposed on one side of the heat sink, and the first heat dissipation member is disposed on the other side of the heat sink.

[0041] In such a laser beauty device, the laser emitting member can emit laser light, the heat sink can expand the heat dissipation area of the laser emitting member and improve the heat dissipation efficiency of the laser emitting member. The heat sink is then thermally conductively connected to the first heat dissipation member, and quickly dissipating the heat of the heat sink can further improve the heat dissipation effect of the laser emitting member.

[0042] In a possible implementation, the second heat dissipation member and the optical waveguide member are respectively thermally conductively connected to the optical waveguide bracket.

[0043] In such a laser beauty device, the second heat dissipation member can absorb the heat of the optical waveguide member through the optical waveguide bracket, thereby realizing the heat dissipation of the optical waveguide member.

[0044] In a possible implementation, the first heat dissipation member includes a first heat dissipation portion and a plurality of first heat dissipation fins. The first heat dissipation portion is thermally conductively connected to the laser light source assembly, the first heat dissipation fins are disposed on the first heat dissipation portion, and a first heat dissipation sub-channel is formed between two adjacent first heat dissipation fins for air flow. And / or, the second heat dissipation member includes a second heat dissipation portion and a plurality of second heat dissipation fins. The second heat dissipation portion is thermally conductively connected to the cold source assembly, the second heat dissipation fins are disposed on the second heat dissipation portion, and a second heat dissipation sub-channel is formed between two adjacent second heat dissipation fins for air flow.

[0045] In such a laser beauty device, the first heat dissipation member includes a plurality of first heat dissipation fins to expand the heat dissipation area, and the first heat dissipation sub-channel formed between the plurality of first heat dissipation fins can realize the air flow. The second heat dissipation member includes a plurality of second heat dissipation fins to expand the heat dissipation area, and the second heat dissipation sub-channel formed between the plurality of second heat dissipation fins can realize the air flow.

[0046] In a possible implementation, the first heat dissipation unit includes a first heat conducting plate and a first heat conducting pipe, the first heat conducting plate is connected to the laser light source assembly by thermal conduction, one end of the first heat conducting pipe is connected to the first heat conducting plate by thermal conduction, and the other end is connected to the plurality of first heat sinks by thermal conduction. And / or, the second heat dissipation unit includes a second heat conducting plate and a second heat conducting pipe, the second heat conducting plate is connected to the cold source assembly by thermal conduction, one end of the second heat conducting pipe is connected to the second heat conducting plate by thermal conduction, and the other end is connected to the plurality of second heat sinks by thermal conduction.

[0047] This laser beauty instrument can conduct heat between the first heat conducting plate and the first heat sink through the first heat conducting pipe. When the setting space of the first heat sink is staggered with the setting space of the first heat conducting plate, the first heat conducting pipe can be used to adapt to the spatial misalignment. When the setting space of the second heat sink is staggered with the setting space of the second heat conducting plate, the second heat conducting pipe can be used to adapt to the spatial misalignment.

[0048] In a possible implementation manner, the first heat dissipation sub-channels and the second heat dissipation sub-channels correspond one-to-one along the first direction.

[0049] In this laser beauty instrument, the airflow outflowing from the first heat dissipation sub-channel can directly enter the second heat dissipation sub-channel along the first direction, thereby reducing the circulation resistance of the airflow.

[0050] In a possible implementation manner, the first heat dissipation portion and the second heat dissipation portion are arranged at intervals along the third direction.

[0051] In this laser beauty instrument, the first heat dissipation part and the second heat dissipation part are arranged at intervals in the third direction, which can reduce the heat conduction between the first heat dissipation part and the second heat dissipation part.

[0052] In a possible implementation, the first heat dissipation portion is a vapor chamber, and / or the second heat dissipation portion is a second vapor chamber.

[0053] In this laser beauty instrument, the heat spreader as the first heat dissipation part can improve the heat conduction efficiency between the first heat sink and the laser light source assembly. The heat spreader as the second heat dissipation part can improve the heat conduction efficiency between the second heat sink and the cold source assembly.

[0054] In a possible implementation, the laser beauty instrument further includes a wind shield, which is disposed on a side of the first heat sink that is away from the laser light source assembly.

[0055] This laser beauty instrument reduces the flow rate of the fluid in the area outside the heat dissipation component through the wind shield, so that more fluid passes through the heat dissipation component, improving the heat dissipation effect of the heat dissipation component. Specifically, the wind shield is arranged on the side of the first heat dissipation component facing away from the laser light source component, thereby improving the heat dissipation effect of the first heat dissipation component. The wind shield can be arranged on the sides of the first heat dissipation component and the second heat dissipation component facing away from the laser light source component at the same time to fill part of the gap between the first heat dissipation component and the second heat dissipation component and the inner wall of the accommodating cavity, increasing the flow rate of the fluid passing through the first heat dissipation component and the second heat dissipation component, and thus improving the heat dissipation effect of the first heat dissipation component and the second heat dissipation component.

[0056] In a possible implementation, the side of the wind shield facing away from the first heat dissipation component abuts against the housing, and the second heat dissipation component abuts against the housing.

[0057] In this laser beauty instrument, when there is a dislocation in the positions of the cold source component and the laser light source component in the third direction, the second heat dissipation component corresponding to the cold source component can directly abut against the housing, while it is difficult for the first heat dissipation component corresponding to the laser light source component to directly abut against the housing. By arranging the wind shield on the side of the first heat dissipation component facing away from the laser light source component and the wind shield abutting against the housing, the air flow at the first heat dissipation component can be made to flow through the first heat dissipation component as much as possible.

[0058] In a possible implementation, from near the heat dissipation driving part to far from the heat dissipation driving part, the wind shield includes a first inclined plate, a flat plate, and a second inclined plate arranged in sequence along the first direction. The flat plate is parallel to the first direction. The first inclined plate inclines away from the first heat dissipation component from near the flat plate to far from the flat plate, and the second inclined plate inclines away from the first heat dissipation component from near the flat plate to far from the flat plate.

[0059] This laser beauty instrument can guide the air flow through the first inclined plate, the flat plate, and the second inclined plate. When the heat dissipation driving part conveys the air flow into the accommodating cavity, the air flow can first be diverted by the first inclined plate to the space between the flat plate and the first heat dissipation part. After the air flow passes through the first heat dissipation sub-channel, the second inclined plate then guides the air flow to flow in the direction of the second heat dissipation component, so that the air flow passes through the second heat dissipation sub-channel.

[0060] In a possible implementation, the laser beauty device further includes two air guide plates. The two air guide plates are disposed in the accommodation cavity and located between the air inlet and the air outlet. An air guide channel extending in the first direction is formed between the two air guide plates. The first heat dissipation member and the second heat dissipation member are at least partially disposed in the air guide channel. The air guide channel is used to guide the air flow to sequentially pass through the first heat dissipation member and the second heat dissipation member. A wind blocking member is disposed in the air guide channel. This laser beauty device can form an air guide channel for guiding the air flow through the two air guide plates, so that the air flow driven by the heat dissipation driving member circulates in the area of the air guide channel to flow through the first heat dissipation member and the second heat dissipation member, reducing the circulation amount of the air flow in the area outside the first heat dissipation member and the second heat dissipation member. The wind blocking member is disposed in the air guide channel, further causing the air flow to concentrate and circulate at the positions where the first heat dissipation member and the second heat dissipation member are located.

[0061] In a possible implementation, the air flow sequentially passes through the first heat dissipation member and the second heat dissipation member in the first direction. The two air guide plates clamp the wind blocking member in the second direction, and the second direction is perpendicular to the first direction.

[0062] In this laser beauty device, the two air guide plates can also limit the position of the wind blocking member and keep the wind blocking member stable in the accommodation cavity.

[0063] In a possible implementation, the laser generated by the laser light source assembly exits from the exit port in the first direction. The cold source assembly includes a thermoelectric cooler and a heat transfer member. The heat transfer member includes a first heat conduction portion and a second heat conduction portion, and the first heat conduction portion and the second heat conduction portion are thermally conductively connected. The first heat conduction portion is thermally conductively connected to the thermoelectric cooler so that the second heat conduction portion is used to form a cold end. The second heat conduction portion is at least partially connected to the inside of the exit port.

[0064] This laser beauty device quickly cools the first heat conduction portion of the heat transfer member through the thermoelectric cooler. The cold quantity is transferred from the first heat conduction portion to the second heat conduction portion, and cold compress is realized for the user through the second heat conduction portion.

[0065] In a possible implementation, the first heat conduction portion and the second heat conduction portion are integrally formed.

[0066] In this laser beauty device, the connection strength between the first heat conduction portion and the second heat conduction portion is high, and the heat conduction effect is high. Moreover, it is convenient for the manufacture of the first heat conduction portion and the second heat conduction portion.

[0067] In a possible implementation, the extending direction of the first heat conduction portion is inclined or perpendicular to the extending direction of the second heat conduction portion

[0068] In this laser beauty device, since the second heat conducting part needs to cool the user's skin, the second heat conducting part needs to be substantially parallel to the user's skin, resulting in the second heat conducting part being substantially perpendicular to the first direction of laser emission. If the first heat conducting part is arranged to be inclined or perpendicular to the second heat conducting part, the size of the laser beauty device in the first direction can be fully utilized, so that the first heat conducting part has a larger size corresponding to a larger-sized cooling sheet, improving the cold compress effect of the cold source assembly.

[0069] In a possible implementation, the first heat conducting part is further provided with a groove, and part of the cooling sheet is received in the groove.

[0070] In this laser beauty device, the side of the cooling sheet for refrigeration can be received in the groove to improve the heat exchange efficiency between the cooling sheet and the first heat conducting part. Moreover, the groove can limit the relative displacement between the first heat conducting part and the cooling sheet, maintaining stable heat conduction between the first heat conducting part and the cooling sheet.

[0071] In a possible implementation, the cooling sheet has opposite refrigerating ends and a heating end. The refrigerating end abuts against the bottom wall of the groove, and the heating end abuts against the second heat dissipating member. The cooling sheet also has an outer side wall located between the refrigerating end and the heating end, and the outer side wall is spaced from the inner side wall of the groove.

[0072] In this laser beauty device, spacing the outer side wall and the inner wall of the groove restricts heat conduction between the refrigerating end and the heating end of the cooling sheet through the first heat conducting part.

[0073] In a possible implementation, the cold source assembly further includes a light transmissive sheet. The light transmissive sheet is disposed in the light transmissive opening, the second heat conducting part is disposed around the light transmissive sheet, and the second heat conducting part is located between the light transmissive sheet and the inner wall of the emission opening.

[0074] This laser beauty device can transmit the laser through the light transmissive sheet, and can also evenly bring the cold quantity at the second heat conducting part to the area where the emission opening is located to achieve cold compress for the user.

[0075] In a possible implementation, the second heat dissipating member includes a second heat dissipating part and a plurality of second heat dissipating fins. The second heat dissipating fins are disposed on the second heat dissipating part. The surface of the second heat dissipating part where the second heat dissipating fins are disposed further has an installation area, and the cooling sheet is disposed in the installation area to be heat-conductively connected to the second heat dissipating part.

[0076] In this laser beauty device, the cooling sheet and the second heat dissipating fins are disposed on the same surface of the second heat dissipating part. This reduces the overall space occupied by the second heat dissipating member and the cooling sheet. Moreover, the surface of the second heat dissipating part facing away from the cooling sheet can also be used for heat transfer of the light guiding member, and heat transfer for the light guiding member with relatively low heat dissipation requirements has little impact on the heat dissipation of the cooling sheet.

[0077] In a possible implementation, the laser beauty instrument further includes a capacitive sensing element, which is disposed at the emission port and is used to sense the skin.

[0078] In this laser beauty instrument, the capacitive sensing element can sense the relative position of the user's skin and the laser hair removal device. When the user's skin and the capacitive sensing element are electrically connected, it is determined that the user's skin is located in the laser emission area, and the cold source component can apply cold compress to the user. At this time, the laser light source component and the cold source component are operated. On the one hand, energy can be saved, and on the other hand, the risk of laser emission to dangerous areas can be reduced.

[0079] In a possible implementation, the second heat conducting portion has a first section and a second section along the first direction, the second section is located on a side of the first section away from the cooling fin, and the capacitive sensing element is sleeved on the outer periphery of the second section and abuts against the first section along the first direction.

[0080] In this laser beauty instrument, one end of the first section facing the second section has a limiting surface. The capacitive sensing element is sleeved on the second section, so that the capacitive sensing element and the second heat conducting part are limited in directions perpendicular to the second direction. The capacitive sensing element abuts against the limiting surface of the first section to limit the capacitive sensing element from further approaching the first heat conducting part along the first direction. An adhesive member can also be provided between the limiting surface and the capacitive sensing element, and the adhesive member bonds the capacitive sensing element and the first section of the second heat conducting part, so that the capacitive sensing element is difficult to move relative to the second heat conducting part along the first direction.

[0174] To make the purpose, technical solution and advantages of the present application clearer, the implementation manners of the present application will be further described in detail below in conjunction with the drawings.

[0175] Figure 1The figure shows a schematic structural view of a laser beauty device 001 provided by the first embodiment of the present application from one perspective. Figure 2 The figure shows a schematic structural view of a laser beauty device 001 provided by the first embodiment of the present application from another perspective.

[0176] As Figure 1 and Figure 2 shown, such a laser beauty device 001 includes a housing 100. The housing 100 has a first dimension along a first direction X, a second dimension along a second direction Y, and a third dimension along a third direction Z. The first direction X, the second direction Y, and the third direction Z are perpendicular to each other. The first dimension is greater than the second dimension and the third dimension, so that in a cross-section perpendicular to the first direction X, the cross-sectional area of such a housing 100 is smaller, facilitating a user to hold the laser beauty device 001. The first direction X forms the length direction of the housing 100, and the housing 100 forms a holding area extending along the length direction.

[0177] At one end along the first direction X, the housing 100 has an emission port 101. The laser beauty device 001 emits laser from the laser emission port 101 to achieve beauty treatment, such as hair removal and / or skin rejuvenation. The effects of beauty treatment are not limited to hair removal or skin rejuvenation. At the other end along the first direction X, the housing 100 further has a charging port, and a power supply plug-in of the laser beauty device 001 is exposed from the charging port. An external power supply cooperates with the power supply plug-in through the charging port, thereby supplying power to the laser beauty device 001.

[0178] Figure 3 The figure shows an assembly schematic view of a laser beauty device 001 provided by the first embodiment of the present application from one perspective. Figure 4 The figure shows an assembly schematic view of a laser beauty device 001 provided by the first embodiment of the present application from another perspective. Figure 5 The figure shows an assembly schematic view of the structure inside the housing 100 of a laser beauty device 001 provided by the first embodiment of the present application.

[0179] As Figure 3 and Figure 4 shown, the housing 100 of such a laser beauty device 001 includes a first half-shell 110 and a second half-shell 130. The first half-shell 110 and the second half-shell 130 are detachably connected along the third direction Z. When the first half-shell 110 and the second half-shell 130 are connected, a receiving cavity 100a is formed between the first half-shell 110 and the second half-shell 130. The laser beauty device 001 further includes a laser light source assembly 200 and a cold source assembly 300. The laser light source assembly 200 is used to emit the laser that is emitted from the emission port 101. The laser is emitted from the emission port 101 along the first direction X and acts on the skin of a user that needs beauty treatment. The cold source assembly 300 has a cold end 301 and a hot end 303 (please refer to Figure 5)。The cold end 301 of the cold source component 300 is disposed at the outlet 101. The cold source component 300 can continuously transfer the heat of the cold end 301 to the hot end 303. That is, the cold source component 300 can continuously take away the heat at the outlet 101 to continuously provide cold at the outlet 101.

[0180] Please refer back to Figure 3 and Figure 4 , the laser beauty device 001 further includes a heat dissipation component 400. The heat dissipation component 400 includes a first heat dissipation member 410 and a second heat dissipation member 430. The first heat dissipation member 410 is thermally conductively connected to the laser light source component 200 to dissipate heat from the laser light source component 200 through the first heat dissipation member 410. The second heat dissipation member 430 is thermally conductively connected to the cold source component 300 to dissipate heat from the cold source component 300 through the second heat dissipation member 430. Along the first direction X, the first heat dissipation member 410 and the second heat dissipation member 430 are spaced apart.

[0181] Wherein, in order to reduce the heat dissipation path of the cold source component 300, the first heat dissipation member 410 is located on the side of the second heat dissipation member 430 away from the outlet 101.

[0182] It can be understood that when the first heat dissipation member 410 is thermally conductively connected to the laser light source component 200, the form of thermal conduction between the first heat dissipation member 410 and the laser light source component 200 can be direct thermal conduction, or a heat conduction structure can be provided between the first heat dissipation member 410 and the laser light source component 200 and thermal conduction can be achieved through the heat conduction structure. The heat conduction structure can be a heat conduction structure such as heat dissipation silicone grease or liquid metal.

[0183] The laser beauty device 001 further includes a heat dissipation driving member 500. The heat dissipation driving member 500 is disposed in the accommodation cavity 100a. When the heat dissipation driving member 500 operates, it drives a fluid to sequentially pass through the first heat dissipation member 410 and the second heat dissipation member 430 in the accommodation cavity 100a, so that the fluid first takes away the heat of the first heat dissipation member 410 and then takes away the heat of the second heat dissipation member 430. Optionally, the heat dissipation driving member 500 includes a heat dissipation fan 510 and the fluid is a gas. The heat dissipation fan 510 drives the gas to flow in the heat dissipation cavity, so that the gas sequentially passes through the first heat dissipation member 410 and the second heat dissipation member 430.

[0184] It should be noted that through the inventor's research, it is found that for the portable laser beauty instrument 001 in this application, the laser light source assembly 200 generates a large amount of heat and has a high heat dissipation requirement. During design, the temperature of the laser light source assembly 200 needs to be controlled below a first preset temperature through the first heat dissipation member 410. For the convenience of detection accuracy and convenience, the temperature of the first heat dissipation member 410 can be controlled below a second preset temperature to control the temperature of the laser light source assembly 200 below the first preset temperature. The cold source assembly 300 generates less heat and has a low heat dissipation requirement. During design, the temperature of the cold source assembly 300 needs to be controlled below a third preset temperature through the second heat dissipation member 430. In actual design, the temperature of the second heat dissipation member 430 can also be controlled below a fourth preset temperature to control the temperature of the cold source assembly 300 below the third preset temperature. It can be understood that the first preset temperature is less than the third preset temperature, and the second preset temperature is less than the fourth preset temperature; for example, in an embodiment, the second preset temperature can be 49, 50 or 51 degrees Celsius, and the fourth preset temperature can be 54, 55 or 56 degrees Celsius.

[0185] In this application, according to the different heat dissipation requirements of the cold source assembly 300 and the laser light source assembly 200, the first heat dissipation member 410 and the second heat dissipation member 430 are sequentially arranged on the heat dissipation path of the heat dissipation driving member 500, so that the heat dissipation fluid can first blow the first heat dissipation member 410 to first dissipate heat from the laser light source assembly 200 to meet its high heat dissipation requirement, and then blow the second heat dissipation member 430 to dissipate heat from the cold source assembly 300, which can meet its low heat dissipation requirement. Thus, the cold source assembly 300 and the laser light source assembly 200 can be respectively dissipated heat through one heat dissipation path, and the overall heat dissipation requirement can be met.

[0186] The first heat dissipation member 410 and the second heat dissipation member 430 are arranged at intervals along the first direction X. It is difficult for the heat of the second heat dissipation member 430 to be directly transferred to the first heat dissipation member 410, reducing the mutual conduction of heat between the first heat dissipation member 410 and the second heat dissipation member 430. It can be understood that when the first heat dissipation member 410 and the second heat dissipation member 430 are arranged at intervals along the first direction X, the first heat dissipation member 410 and the second heat dissipation member 430 are generally arranged along the first direction X, but the first heat dissipation member 410 and the second heat dissipation member 430 can also be staggered along the second direction Y or the third direction Z, so that there is a gap along the second direction Y or the third direction Z between the first heat dissipation member 410 and the second heat dissipation member 430.

[0187] The laser emission direction is the first direction X, and the arrangement directions of the first heat dissipation member 410 and the second heat dissipation member 430 are also the first direction X. The setting directions of the first heat dissipation member 410 and the second heat dissipation member 430 match the laser emission direction, which can reduce the overall size of the laser beauty instrument 001 perpendicular to the first direction X and facilitate the user to hold the laser beauty instrument 001 by hand.

[0188]

[0188] Optionally, the heat dissipation fan 510 is disposed on a side of the first heat dissipation member 410 facing away from the second heat dissipation member 430. The heat dissipation fan 510 can introduce the gas outside the housing 100 into the accommodation cavity 100a, and sequentially pass through the heat dissipation fan 510, the first heat dissipation member 410, and the second heat dissipation member 430. When the gas outside the housing 100 contains dust and other debris, the dust and other debris will first adhere to the heat dissipation fan 510, which can reduce the probability of the debris adhering to the first heat dissipation member 410 and the second heat dissipation member 430. Furthermore, when cleaning and maintaining the laser beauty device 001, the cleaning and maintenance cycle of the first heat dissipation member 410 and the second heat dissipation member 430 can be extended.

[0189]

[0189] The laser beauty device 001 further includes a control unit 600. The heat dissipation driving member 500, the laser light source assembly 200, and the cold source assembly 300 are all electrically connected to the control unit 600. The operation of the heat dissipation driving member 500, the laser light source assembly 200, and the cold source assembly 300 is controlled by the control unit 600. Optionally, the control unit 600 includes a first circuit board 610. The heat dissipation driving member 500, the laser light source assembly 200, and the cold source assembly 300 are all electrically connected to the first circuit board 610. The first circuit board 610 is printed with circuits for controlling the operation of the heat dissipation driving member 500, the laser light source assembly 200, and the cold source assembly 300. When the first circuit board 610 controls the operation of the laser light source assembly 200 and the cold source assembly 300, the first circuit board 610 also controls the heat dissipation driving member 500 to operate to generate an air flow, and the air flow flows through the first heat dissipation member 410 and the second heat dissipation member 430 to dissipate heat from the laser light source assembly 200 and the cold source assembly 300. After the cold source assembly 300 and the laser light source assembly 200 stop operating, the first circuit board 610 also controls the heat dissipation driving member 500 to continue operating for a preset time, so that the air flow continuously flows through the first heat dissipation member 410 and the second heat dissipation member 430, and cools the cold source assembly 300 and the laser light source assembly 200 to approximately room temperature.

[0190] Optionally, both the air outlet 113 and the air inlet 111 are provided on the first half shell 110, and the air inlet 111 and the air outlet 113 are spaced apart along the first direction X. Along the first direction X, the first heat sink 410 and the second heat sink 430 are at least partially located between the air inlet 111 and the air outlet 113. The first heat sink 410 is provided on the side of the laser light source assembly 200 facing the first half shell 110, and the second heat sink 430 is also provided on the side of the laser light source assembly 200 facing the first half shell 110. The heat dissipation driving member 500 is provided on the side of the first circuit board 610 facing the first half shell 110. The heat dissipation driving member 500 drives the gas to be substantially distributed on the side of the accommodation cavity 100a where the first heat sink 410 and the second heat sink 430 are provided, and flows substantially along the first direction X. Concentrating the air flow on the side of the accommodation cavity 100a where the first heat sink 410 and the second heat sink 430 are provided enables the gas in the accommodation cavity 100a to flow through the first heat sink 410 and the second heat sink 430 as much as possible, improving the utilization rate of air flow heat dissipation. It can be understood that if the first half shell 110 and the second half shell 130 are detachably connected along the second direction Y, the air outlet 113 can be partially provided on the first half shell 110 and partially provided on the second half shell 130. The air inlet can also be partially provided on the first half shell 110 and partially provided on the second half shell 130. The air outlet 113 and the air inlet are preferably provided on the same side of the housing 100 along the third direction Z, so that the air flow flows substantially on the same side of the accommodation cavity 100a along the third direction Z, that is, the air flow flows substantially on the side of the accommodation cavity 100a where the first heat sink 410 and the second heat sink 430 are provided. It can be understood that the air inlet 111 and the air outlet 113 may not be on the same side in the third direction Z, and the air inlet 111 and the air outlet 113 are staggered along the first direction X, so that the air flow in the accommodation cavity 100a flows substantially along the first direction X, but also penetrates the accommodation cavity 100a in the third direction Z. The air inlet 111 and the air outlet 113 have a spacing in the first direction X, so that a gripping area for the user to grip is formed between the air inlet 111 and the air outlet 113.

[0191] Optionally, the air inlet 111 includes a plurality of air inlet holes 1111. The plurality of air inlet holes 1111 are arranged in an array on the housing 100. Each air inlet hole 1111 is generally in the shape of a circular hole. The plurality of air inlet holes 1111 constitute the air inlet 111, so that the overall ventilation area of the air inlet 111 is large. On the premise that the entire air inlet 111 can provide air flow for the first heat sink 410 and the second heat sink 430, the size of each air inlet hole 1111 is small, so as to shield some larger-sized sundries from entering the accommodation cavity 100a along with the air flow, so as to protect the components in the accommodation cavity 100a, such as the laser light source assembly 200 and the cold source assembly 300. It can be understood that the shape of the air inlet hole 1111 is not limited to the circular hole shape, and can also be hexagonal or other shapes. A dust-proof mesh cover can also be provided at the air inlet 111 to limit dust from entering the accommodation cavity 100a through the air inlet 111, thereby protecting the components in the accommodation cavity 100a.

[0192] Optionally, the area on the first half shell 110 where the air inlet 111 is provided is the air inlet area. The air inlet area protrudes along the third direction Z, so that the accommodation cavity 100a corresponding to the air inlet area has a larger space in the third direction Z than the accommodation cavity 100a corresponding to the holding area. The heat dissipation driving member 500 is disposed in the accommodation cavity 100a corresponding to the air inlet area. This laser beauty device 001 can accommodate a heat dissipation driving member 500 with a larger size in the third direction Z. In other words, this laser beauty device 001 can accommodate a heat dissipation driving member 500 with a larger working power, so as to provide a better heat dissipation effect for the first heat sink 410 and the second heat sink 430. On the other hand, the air inlet area of the first half shell 110 protruding along the third direction Z can also prevent the user's hand from easily slipping to the air inlet area to block the air inlet 111 when the user holds the holding area, so as to maintain the air intake volume when the laser beauty device 001 is running.

[0193] Figure 6 Fig. shows a schematic structural view of the structure inside the housing 100 in the laser beauty device 001 provided by the first embodiment of the present application from a perspective. Figure 7 Fig. shows a cross-sectional view of the laser beauty device 001 provided by the first embodiment of the present application.

[0194] Please refer to Figure 6, the laser light source assembly 200 includes a laser 210. The laser beauty instrument further includes an optical waveguide 230. Along the first direction X, the optical waveguide 230 is disposed between the laser 210 and the exit port 101. The laser 210 is electrically connected to the first circuit board 610, and the laser 210 is controlled by the first circuit board 610 to emit laser light. When the laser 210 emits laser light, the laser light exits from the exit port 101 after passing through the optical waveguide 230. The first heat sink 410 is thermally conductively connected to the laser 210. When the laser 210 emits laser light, the laser 210 generates heat, and the heat is conducted to the first heat sink 410 and taken away by the fluid flowing through the first heat sink 410. Optionally, the first heat sink 410 is also thermally conductively connected to the optical waveguide 230. When the laser light passes through the optical waveguide 230, the optical waveguide 230 absorbs part of the energy of the laser light and generates heat, and the heat is conducted to the first heat sink 410 and taken away by the fluid flowing through the first heat sink 410. When the laser 210 emits laser light and the laser light passes through the optical waveguide 230, the heat generated by the laser 210 is higher than that of the optical waveguide 230. The first heat sink 410 mainly dissipates heat from the laser 210, and tries to keep the laser 210 at the operating temperature so that the laser 210 can continuously operate normally. Along the first direction X, the optical waveguide 230 extends from the laser 210 to the exit port 101 and passes through the area where the cold source assembly 300 is located. The second heat sink 430 is located on the side of the optical waveguide 230 facing the first sub-shell. The optical waveguide 230 can also limit the airflow from flowing into the side of the accommodation cavity 100a close to the second sub-shell, so as to keep the airflow flowing in the area of the accommodation cavity 100a close to the first sub-shell as much as possible.

[0195] The optical waveguide 230 is generally in the shape of a quadrangular prism. The four edges parallel to the optical waveguide 230 are arranged parallel to the third direction Z. Along the first direction X, the optical waveguide 230 has opposite large surface ends 231 and small surface ends 233, and the end surface area of the large surface end 231 is larger than that of the small surface end 233. The small surface end 233 faces the exit port 101, and the large surface end 231 faces the laser 210. After the laser light emitted by the laser 210 enters the optical waveguide 230 from the large surface end 231, it is conducted to the small surface end 233 through the conductive member and exits from the exit port 101.

[0196] Optionally, the laser light source assembly 200 further includes a laser bracket 250. The laser 210 is clamped on the laser bracket 250, so that the laser 210 and the laser bracket 250 maintain a stable positional relationship. The laser bracket 250 is thermally conductively connected to the first heat sink 410, so that the heat of the laser 210 can be conducted to the first heat sink 410 through the laser bracket 250. The laser bracket 250 is provided with a first connection hole 251, and the first heat sink 410 is provided with a second connection hole 411. The laser beauty device 001 further includes a first connecting member (not shown in the figure). The first connecting member passes through the first connection hole 251 and the second connection hole 411 to connect the laser bracket 250 and the first heat sink 410. For example, the first connecting member includes a first bolt. After the first bolt passes through the first connection hole 251 and the second connection hole 411, it is threadedly engaged with the first threaded hole on the first half shell 110, so that the laser bracket 250 and the first heat sink 410 can be connected by the first bolt and the first half shell 110. And the laser 210 is clamped on the laser bracket 250, so that a relatively stable positional relationship can be maintained between the laser 210 and the first heat sink 410.

[0197] Optionally, the laser beauty device 001 further includes an optical guide bracket 700. The optical guide bracket 700 connects the optical guide member 230 and the first heat sink 410. Specifically, the optical guide bracket 700 has a clamping groove 701. When the optical guide bracket 700 is connected to the first heat sink 410, the optical guide member 230 is clamped in the clamping groove 701 of the optical guide bracket 700. The optical guide bracket 700 is clamped on the portion of the optical guide member 230 located at the large surface end 231. Along the first direction X, the cross-sectional area of the optical guide bracket 700 gradually increases from the end close to the light exit port 101 to the end close to the laser 210. Based on the change in the cross-sectional area of the optical guide member 230 along the first direction X, when the optical guide bracket 700 clamps the optical guide member 230, the inner wall of the clamping groove 701 can also limit the optical guide member 230 from moving away from the laser 210 along the first direction X.

[0198] Optionally, the optical waveguide 230 is thermally conductively connected to the first heat sink 410 so that the heat of the optical waveguide 230 can be transferred to the first heat sink 410. The optical waveguide bracket 700 is provided with a third connection hole 703, and the first heat sink 410 is provided with a fourth connection hole 412. The laser beauty device 001 further includes a second connecting member (not shown in the figure). The second connecting member passes through the third connection hole 703 and the fourth connection hole 412 to connect the optical waveguide bracket 700 and the first heat sink 410. For example, the second connecting member includes a second bolt. After the second bolt passes through the third connection hole 703 and the fourth connection hole 412, it is threadedly engaged with the second threaded hole on the first half shell 110, so that the optical waveguide bracket 700 and the first heat sink 410 can be connected by the second bolt. The optical waveguide bracket 700 may include a plurality of detachable parts and be assembled when the optical waveguide bracket 700 is needed. Specifically, the optical waveguide bracket 700 may include a first bracket body 710 and a second bracket body 730. The first bracket body 710 is connected to the first heat sink 410. The second bracket body 730 is located at a position of the first bracket body 710 away from the first heat sink 410 and is detachably connected to the first bracket body 710. When the optical waveguide 230 needs to be maintained, only the second bracket body 730 can be detached from the first bracket body 710, and the connection between the first bracket body 710 and the first heat sink 410 keeps the positions of the optical waveguide 230 and the first heat sink 410 stable. The detachment of the second bracket body 730 exposes the part of the optical waveguide 230 away from the first heat sink 410, facilitating the maintenance personnel to observe the state of the laser in the optical waveguide 230.

[0199] Optionally, along the third direction Z, the optical waveguide 230 protrudes from the laser 210, and the surface of the first heat sink 410 close to the laser 210 is not flush with the surface of the second heat sink 430 close to the cold source assembly 300. The surface of the first heat sink 410 close to the laser 210 and the surface of the second heat sink 430 close to the cold source assembly 300 are spaced apart along the third direction Z.

[0200] Optionally, the laser 210 includes a laser emitting member 211 and a heat sink 213. The laser emitting member 211 is connected to the heat sink 213. The laser emitting member 211 is used for emitting laser, and the heat sink 213 is used for absorbing the heat of the laser emitting member 211. The heat sink 213 can expand the heat dissipation area of the laser 210, and the connection between the heat sink 213 and the laser bracket 250 can accelerate the heat transfer between the laser emitting member 211 and the laser bracket 250. The heat sink 213 is fixedly connected to the laser emitting member 211 when the laser emitting member 211 is encapsulated. On the one hand, it can protect the laser emitting member 211, and on the other hand, it can maintain the stable contact between the laser emitting member 211 and the heat sink 213, thereby maintaining the heat conduction performance between the laser emitting member 211 and the heat sink 213.

[0201] Please refer to Figure 5 、 Figure 6 andFigure 7 , optionally, the cold source assembly 300 includes a thermoelectric cooler 310 and a heat transfer member 330. The thermoelectric cooler 310 is a thermoelectric cooler (TEC). The thermoelectric cooler 310 has opposite cooling end 311 and heating end 313. When the thermoelectric cooler 310 is powered on, it can continuously collect the heat at the cooling end 311 to the heating end 313, so that a large temperature difference is formed between the cooling end 311 and the heating end 313 of the thermoelectric cooler 310. The heating end 313 of the thermoelectric cooler 310 forms the hot end 303 of the cold source assembly 300, and the heat transfer member 330 forms the cold end 301 of the cold source assembly 300.

[0202] When the first side of the thermoelectric cooler 310 is connected to the heat transfer member 330 and provides cold quantity to the heat transfer member 330, the second side of the thermoelectric cooler 310 needs to dissipate heat quickly to reduce heat accumulation. The second heat sink 430 is thermally conductively connected to the second side of the thermoelectric cooler 310, so as to quickly dissipate the heat on the second side.

[0203] The heat transfer member 330 includes a first heat conduction portion 331 and a second heat conduction portion 333. The first heat conduction portion 331 and the second heat conduction portion 333 are bent and connected. The first heat conduction portion 331 and the second heat conduction portion 333 are generally L-shaped. Optionally, the first heat conduction portion 331 and the second heat conduction portion 333 are integrally formed. The integrally formed form of the first heat conduction portion 331 and the second heat conduction portion 333 can be various. For example, the first heat conduction portion 331 and the second heat conduction portion 333 can be formed by integral casting. It can also be formed by machining a whole metal block in different regions to form the first heat conduction portion 331 and the second heat conduction portion 333. It can also be formed by stamping and bending a metal plate to form the first heat conduction portion 331 and the second heat conduction portion 333.

[0204] Optionally, the extending direction of the first heat conduction portion 331 is substantially perpendicular to the extending direction of the second heat conduction portion 333. The first heat conduction portion 331 is in a plate-like structure, and the second heat conduction portion 333 is also in a plate-like structure, and the first heat conduction portion 331 and the second heat conduction portion 333 are substantially perpendicular. When the second heat conduction portion 333 is arranged at the outlet 101 at one end of the housing 100 along the first direction X, the first heat conduction portion 331 can extend parallel to the first direction X, so as to make full use of the space of the accommodation cavity 100a and reduce the space occupied by the heat transfer member 330 in the third direction Z. The second heat sink 430 is thermally conductively connected to the first heat conduction portion 331, so that the second heat sink 430 can have a large contact area with the first heat conduction portion 331 on the plane parallel to the first direction X and the second direction Y, so as to improve the thermal conduction performance between the first heat conduction portion 331 and the second heat sink 430.

[0205] The second heat conduction part 333 is provided with a light-transmitting opening 3331. The small surface end 233 of the light guide member 230 extends into the light-transmitting opening 3331. After the laser exits from the small surface end 233 of the light guide member 230 along the first direction X, it can continue to exit from the light-transmitting opening 3331 along the first direction X.

[0206] Optionally, one end of the second heat conduction part 333 along the first direction X can penetrate out of the light-emitting port 101. When the user uses the laser beauty instrument 001, the part of the second heat conduction part 333 that penetrates out of the light-emitting port 101 can contact the user's skin. The second heat conduction part 333 directly provides cold for the user's skin to realize cold compress on the user's skin.

[0207] Optionally, the heat transfer member 330 can be made of a metal material with high thermal conductivity. For example, pure copper or copper alloy can be used. So that the first heat conduction part 331 and the second heat conduction part 333 can transfer heat quickly, thereby improving the cold compress effect of the cold source assembly 300.

[0208] Optionally, the first heat conduction part 331 has a groove 3311, and the refrigeration sheet 310 is partially accommodated in the groove 3311. The refrigeration end 311 of the refrigeration sheet 310 abuts against the bottom wall of the groove 3311, and the heating end 313 extends out of the groove 3311 and abuts against the second heat dissipation member 430. Through the groove 3311 of the first heat conduction part 331, the position of the refrigeration sheet 310 can be restricted, and the refrigeration sheet 310 being partially accommodated in the groove 3311 can restrict the air flow in the area where the refrigeration sheet 310 is located, and restrict the convective heat transfer between the refrigeration end 311 and the heating end 313 of the refrigeration sheet 310.

[0209] Optionally, the refrigeration sheet 310 also has an outer side wall 315 located between the refrigeration end 311 and the heating end 313, and the outer side wall 315 is spaced from the inner side wall of the groove 3311. Spacing the outer side wall 315 and the inner wall of the groove 3311 restricts the heat conduction between the refrigeration end 311 and the heating end 313 of the refrigeration sheet 310 through the first heat conduction part 331. Optionally, the cold source assembly 300 further includes a light-transmitting sheet 350. The light-transmitting sheet 350 is arranged in the light-transmitting opening 3331, and the laser can exit from the light-transmitting sheet 350 along the first direction X. The light-transmitting sheet 350 is thermally conductively connected to the second heat conduction part 333, so that the cold of the second heat conduction part 333 can also be conducted to the light-transmitting sheet 350. When the light-transmitting sheet 350 contacts the user's skin, the light-transmitting sheet 350 provides cold for the user's skin to realize cold compress on the user's skin. Optionally, the material of the light-transmitting sheet 350 is sapphire, and sapphire has the characteristics of high light transmittance and good thermal conduction performance, which can not only make the laser transmit through the sapphire, but also conduct the cold of the second heat conduction part 333 to the user's skin.

The first section 3333 is connected to the first heat conducting portion 331, and the second section 3335 is located on the side of the first section 3333 away from the first heat conducting portion 331. In the projection plane along the first direction X, the projection of the second section 3335 is located within the projection of the first section 3333, so that the end face of the first section 3333 facing the second section 3335 forms a limiting surface 3337. The capacitive sensing element 800 has a sleeve hole 801. The second section 3335 passes through the sleeve hole 801, so that the capacitive sensing element 800 is sleeved on the second section 3335. The capacitive sensing element 800 abuts against the limiting surface 3337 of the first section 3333, and the capacitive sensing element 800 is restricted from approaching the first heat conducting portion 331 further along the first direction X through the limiting surface 3337. When the cold source assembly 300 is disposed inside the housing 100, the inner wall of the housing 100 and the limiting surface 3337 jointly clamp the capacitive sensing element 800, so that the relative position of the capacitive sensing element 800 with respect to the housing 100 and the heat transfer member 330 in the first direction X is fixed. The capacitive sensing element 800 is electrically connected to the heat transfer member 330, and the capacitive sensing element 800 is also electrically connected to the first circuit board 610. When the user's skin contacts the heat transfer member 330, the user's skin is electrically connected to the capacitive sensing element 800, and the capacitive sensing element 800 sends a signal to the first circuit board 610, and the first circuit board 610 determines that the cold source assembly 300 contacts the user's skin. When the user's skin no longer contacts the heat transfer member 330, the user's skin is electrically disconnected from the capacitive sensing element 800, the capacitive sensing element 800 no longer sends a signal to the first circuit board 610, and the first circuit board 610 determines that the cold source assembly 300 leaves the user's skin.

[0212] Optionally, the first heat sink 410 includes a first heat sink 413 and a plurality of first heat sinks 415. The first heat sink 413 is substantially in the form of a plate body perpendicular to the third direction Z. The plurality of first heat sinks 415 are fixedly disposed on a side of the first heat sink 413 facing the first half shell 110. A first heat sink branch channel 415a is formed between two adjacent first heat sinks 415. The first heat sink 415 extends parallel to the first direction X, and the first heat sink branch channel 415a also extends parallel to the first direction X. The heat dissipation fan 510 is a centrifugal fan. The air inlet end of the centrifugal fan faces the air inlet 111, and the air outlet end faces the first heat sink 415. The centrifugal fan can inhale gas from the air inlet 111 along the third direction Z, and blow the gas toward the first heat sink branch channel 415a along the first direction X. The gas circulates in the plurality of first heat sink branch channels 415a to take away the heat of the first heat sink 415.

[0213] The side of the first heat dissipation part 413 facing away from the first heat sink 415 is connected to the laser light source assembly 200 by thermal conduction. Specifically, the side of the first heat dissipation part 413 facing away from the first heat sink 415 is connected to the laser bracket 250 by thermal conduction. The heat generated by the laser 210 is conducted to the first heat dissipation part 413 through the laser bracket 250, and then conducted to the plurality of first heat sinks 415 through the first heat dissipation part 413. When the airflow flows through the first heat dissipation branch channel 415a, the heat of the first heat sink 415 is taken away.

[0214] Optionally, the first heat dissipation portion 413 is a heat spreader. The heat spreader contains a heat spreader coolant, which can be repeatedly vaporized and condensed to improve the heat conduction efficiency of the heat spreader on both sides along the third direction Z. Such a first heat dissipation portion 413 can quickly conduct the heat of the laser light source assembly 200 to the first heat sink 415, thereby improving the heat dissipation efficiency of the first heat sink 410.

[0215] Optionally, the first heat dissipation portion 413 is a heat pipe. The heat pipe is connected to the laser light source assembly 200 by thermal conduction. For example, the heat pipe directly contacts the laser light source assembly 200, so that the heat of the laser light source assembly 200 is transferred to the heat pipe. For another example, the heat pipe is connected to the laser light source assembly 200 by thermal conduction through a heat conductive material such as heat dissipation silicone grease, and the laser light source assembly 200 transfers the heat to the heat dissipation silicone grease, and the heat dissipation silicone grease is then transferred to the heat pipe.

[0216] Figure 9 It is a schematic structural diagram of a first heat sink and a second heat sink provided in another embodiment of the present application.

[0217] Please refer to Figure 9, optionally, the first heat dissipation part 413 may further include a first heat conducting plate 4131 and a first heat conducting tube 4133. The first heat conducting plate 4131 is thermally connected to the laser light source assembly 200. One end of the first heat conducting tube 4133 is thermally connected to the first heat conducting plate 4131, and the other end is thermally connected to a plurality of first heat dissipation fins 415. The first heat conducting tube 4133 can transfer heat between the first heat conducting plate 4131 and the first heat dissipation fins 415, transferring the heat of the first heat conducting plate 4131 to the plurality of first heat dissipation fins 415. The first heat conducting plate 4131 and the first heat dissipation fins 415 do not have to be directly connected, and the first heat conducting plate 4131 corresponding to the laser light source assembly 200 can be misaligned with the first heat dissipation fins 415, making the spatial layout in the accommodation cavity 100a more flexible.

[0218] , optionally, the second heat dissipation member 430 includes a second heat dissipation part 433 and a plurality of second heat dissipation fins 435. The second heat dissipation part 433 is generally a plate body perpendicular to the third direction Z. The plurality of second heat dissipation fins 435 are fixedly arranged on the surface of the second heat dissipation part 433 facing the first half shell 110. A second heat dissipation sub-channel 435a is formed between two adjacent second heat dissipation fins 435. The second heat dissipation fins 435 extend parallel to the first direction X, and the second heat dissipation sub-channel 435a also extends parallel to the first direction X. The first heat dissipation sub-channel 415a communicates with the second heat dissipation sub-channel 435a along the first direction X. The gas flowing through the first heat dissipation sub-channel 415a can enter the second heat dissipation sub-channel 435a and flow therein. The gas flows in the plurality of second heat dissipation sub-channels 435a to take away the heat of the second heat dissipation fins 435.

[0219] Please refer to Figure 3 and Figure 4 , optionally, the air outlet 113 includes a plurality of air outlet holes 1131. The plurality of air outlet holes 1131 are arranged in an array on the housing 100. Each air outlet hole 1131 is generally a kidney-shaped hole. The plurality of air outlet holes 1131 constitute the air outlet 113, making the overall ventilation area of the air outlet 113 large, and the air flow in the accommodation cavity 100a can be smoothly discharged through the air outlet 113. The air outlet holes 1131 generally extend along the second direction Y, so that each air outlet hole 1131 can simultaneously correspond to a plurality of second heat dissipation sub-channels 435a in the second heat dissipation member 430, enabling the air flow flowing in the plurality of second heat dissipation sub-channels 435a to flow out of the accommodation cavity 100a evenly.

[0220] Along the third direction Z, the position of the air outlet 113 corresponds to the position of the second heat sink 430. Optionally, on the projection plane perpendicular to the third direction Z, the projection of the air outlet 113 is located within the projection of the second heat sink 430. The air flow in the accommodation cavity 100a will preferably flow through the second heat sink 430 first and then flow out of the accommodation cavity 100a through the air outlet 113, thereby improving the heat dissipation effect of the air flow on the second heat sink 430. It can be understood that the projection of the air outlet 113 can also be partially located within the projection of the second heat sink 430 and partially located within the projection of the first heat sink 410. Such that some of the air outlet holes 1131 are arranged corresponding to the first heat sink 410, and some of the air outlet holes 1131 are arranged corresponding to the second heat sink 430. Part of the air flow flowing through the first heat sink 410 will directly flow out of the accommodation cavity 100a through the air outlet holes 1131, and the other part of the air flow will flow out of the accommodation cavity 100a through the second heat sink 430. When the heat dissipation driving member 500 inputs a high air pressure air flow into the accommodation cavity 100a from the air inlet 111, the larger area of the air outlet 113 can maintain the air pressure in the accommodation cavity 100a, and part of the air flow flowing through the second heat sink 430 can also ensure the heat dissipation requirements of the cold source assembly 300.

[0221] One side of the second heat dissipation part 433 facing away from the second heat sink 435 is thermally conductively connected to the cold source assembly 300. Specifically, one side of the second heat dissipation part 433 facing away from the second heat sink 435 is thermally conductively connected to the refrigeration chip 310. The heat generated by the refrigeration chip 310 is conducted to the second heat dissipation part 433, and then conducted to the plurality of second heat sinks 435 through the second heat dissipation part 433. When the air flow flows through the second heat dissipation sub-channel 435a, the heat of the second heat sink 435 is carried away.

[0222] Optionally, the second heat dissipation part 433 is a heat pipe. The heat pipe is thermally conductively connected to the laser light source assembly 200. For example, the heat pipe is in direct contact with the cold source assembly 300, such that the heat of the cold source assembly 300 is transferred to the heat pipe. For another example, the heat pipe is thermally conductively connected to the cold source assembly 300 through a heat conductive material such as heat dissipation silicone grease. The cold source assembly 300 transfers the heat to the heat dissipation silicone grease, and the heat dissipation silicone grease then conducts it to the heat pipe.

[0223] Optionally, the second heat dissipation part 433 is a vapor chamber. The vapor chamber contains a vapor chamber coolant, and the vapor chamber coolant can repeatedly vaporize and condense to improve the heat conduction efficiency of both sides of the vapor chamber along the third direction Z. Such a second heat dissipation part 433 can quickly conduct the heat of the cold source assembly 300 to the second heat sink 435, improving the heat dissipation efficiency of the second heat sink 430.

[0224] Optionally, the second heat dissipation part 433 may further include a second heat conduction plate 4331 and a second heat conduction pipe 4333.

One end of the second heat conduction pipe 4333 is thermally connected to the second heat conduction plate 4331, and the other end is thermally connected to a plurality of second heat dissipation fins 435. The second heat conduction pipe 4333 can transfer heat between the second heat conduction plate 4331 and the second heat dissipation fins 435, and transfer the heat of the second heat conduction plate 4331 to the plurality of second heat dissipation fins 435. The second heat conduction plate 4331 and the second heat dissipation fins 435 do not have to be directly connected, and the second heat conduction plate 4331 corresponding to the laser light source assembly 200 can be misaligned with the second heat dissipation fins 435, making the spatial layout in the accommodation cavity 100a more flexible.

[0225] Optionally, an air guiding channel 151 is further formed in the accommodation cavity 100a of the housing 100. The first heat dissipation fins 415 of the first heat dissipation member 410 are located in the air guiding channel, and the second heat dissipation fins 435 of the second heat dissipation member 430 are located in the air guiding channel 151. The first heat dissipation member 410 and the second heat dissipation member 430 can partially block the opening of the air guiding channel 151 to limit the fluid in the air guiding channel 151 from escaping through the opening. The air guiding channel 151 is used to guide the fluid to pass through the first heat dissipation member 410 and the second heat dissipation member 430 in sequence. The housing 100 further includes two air guiding plates 150. The two air guiding plates 150 are arranged in the accommodation cavity 100a, and the two air guiding plates 150 are close to the side of the housing 100 where the air inlet 111 and the air outlet 113 are provided. The air guiding plates 150 extend substantially parallel to the first direction X, and an air guiding channel 151 is formed between the two air guiding plates 150. The air guiding channel 151 is used to guide the fluid to pass through the first heat dissipation member 410 and the second heat dissipation member 430 in sequence. The first heat dissipation fins 415 of the first heat dissipation member 410 are located in the air guiding channel, and the second heat dissipation fins 435 of the second heat dissipation member 430 are located in the air guiding channel 151. The two air guiding plates 150 reduce the flow rate of the fluid in the area outside the first heat dissipation member 410 and the second heat dissipation member 430, increase the flow rate of the fluid in the area where the first heat dissipation member 410 and the second heat dissipation member 430 are located, and thus improve the heat dissipation effect of the first heat dissipation member 410 and the second heat dissipation member 430.

[0226] It can be understood that the relationship between the two air guiding plates 150 and the first half shell 110 can be in various forms. For example, the two air guiding plates 150 are integrally formed with the first half shell 110. Or, the two air guiding plates 150 are separately manufactured and then fixedly connected to the first half shell 110. Or, the two air guiding plates 150 are separately manufactured and fixedly connected to the first heat dissipation member 410 or the second heat dissipation member 430. When the first heat dissipation member 410 or the second heat dissipation member 430 is arranged in the housing 100, the two air guiding plates 150 are close to the inner wall of the first half shell 110.

[0227] Understandably, the laser beauty device 001 may further include a wind shield 170, which is located at both ends of the wind guide plate 150 along the first direction X. By restricting the flow of air in the first direction X, the wind shield 170 further restricts the flow rate of air in the area outside the first heat dissipation member 410 and the second heat dissipation member 430. The number of wind shields 170 is two. Along the first direction X, the air inlet 111 and the air outlet 113 are at least partially located between the two wind shields 170. Understandably, the wind shield 170 can be integrally formed with the two wind guide plates 150.

The size of this housing 100 along the first direction X is greater than the size along the second direction Y or the third direction Z. The first direction X, the second direction Y, and the third direction Z are perpendicular to each other. In a cross-section perpendicular to the first direction X, the cross-sectional area of this housing 100 is small, which is convenient for the user to hold the laser beauty device 001.

[0231] At one end along the first direction X, the housing 100 has an emission port 101. The laser beauty device 001 emits laser from the laser emission port 101 to achieve beauty treatment.

[0232] Please refer to Figure 11 and Figure 12 , the differences between this kind of laser beauty device 001 and the laser beauty device 001 in the first embodiment include:

[0233] The Peltier cooler 310 is disposed on one side of the second heat dissipation part 433 closer to the air outlet 113 in the third direction Z. An installation area is provided on the surface of the second heat dissipation part 433 where the second heat sink 435 is provided, and the Peltier cooler 310 is disposed in the installation area such that the Peltier cooler 310 and the second heat sink 435 are on the same surface of the second heat dissipation part 433. The Peltier cooler 310 and the second heat sink 435 being on the same surface of the second heat dissipation part 433 can reduce the space occupied by the Peltier cooler 310 and the second heat dissipation member 430 in the third direction Z. The surface of the second heat dissipation part 433 facing away from the second heat sink 435 can be thermally conductive and cooperate with the light guide member 230, such that the second heat dissipation member 430 also dissipates heat from the light guide member 230. Specifically, the light guide member 230 is connected to the second heat dissipation member 430 through the light guide bracket 700, improving the position stability of the second heat dissipation member 430 or the light guide member 230. Optionally, if the light guide bracket 700 is made of a heat-conductive material, the heat of the light guide member 230 can also be conducted to the second heat dissipation member 430 through the light guide bracket 700, and the second heat dissipation member 430 dissipates heat from the light guide member 230.

[0234] Figure 13 Fig. shows an assembly schematic diagram of another perspective of the laser beauty device 001 provided by the second embodiment of the present application.

[0235] Please refer to Figure 12 and Figure 13 Optionally, the light guide bracket 700 includes a first frame body 710 and a second frame body 730. The first frame body 710 and the second frame body 730 are detachably connected along the third direction Z, such that the light guide member 230 is clamped between the first frame body 710 and the second frame body 730. The first frame body 710 is connected to the second heat dissipation part 433, and the heat of the light guide member 230 can be conducted to the second heat dissipation part 433 through the first frame body 710.

[0236] It can be understood that the light guide member 230 can dissipate heat through the first heat dissipation member 410 and the second heat dissipation member 430 simultaneously. The light guide bracket 700 includes a first bracket portion and a second bracket portion. The first bracket portion connects the portion of the light guide member 230 close to the light exit 101 to the second heat dissipation member 430. The second bracket portion connects the portion of the light guide member 230 close to the laser 210 to the first heat dissipation member 410. The first bracket portion and the second bracket portion can be fixedly connected or separately arranged.

[0237] The laser beauty device 001 further includes a wind shield 900. The wind shield 900 is disposed on the side of the heat dissipation component 400 away from the laser light source component 200. The wind shield 900 can be clamped between the heat dissipation component 400 and the housing 100, and at least part of the gap between the heat dissipation component 400 and the inner wall of the accommodation cavity 100a is filled by the wind shield 900 to direct the fluid flow towards the heat dissipation component 400. The wind shield 900 is disposed between the two air guide plates 150 and can compress the space in the air guide channel 151. The wind shield 900 guides the gas to the positions where the first heat dissipation member 410 and the second heat dissipation member 430 are located, improving the gas flow rate in the first heat dissipation sub-channel 415a and the second heat dissipation sub-channel 435a to dissipate heat from the first heat dissipation member 410 and the second heat dissipation member 430.

[0238] Optionally, the first frame body 710 occupies a part of the space on one side of the light guide member 230 along the third direction Z, resulting in an increase in the position difference between the first heat dissipation member 410 and the second heat dissipation member 430 in the third direction Z. The wind shield 900 is disposed between the first heat dissipation member 410 and the housing 100, which can reduce the influence of the position difference between the first heat dissipation member 410 and the second heat dissipation member 430 in the third direction Z on the heat dissipation effect of the first heat dissipation member 410. The wind shield 900 includes a first inclined plate 910, a flat plate 930, and a second inclined plate 950 arranged in sequence along the first direction X. The flat plate 930 and the inner wall of the housing 100 are spaced apart along the third direction Z to compress the space in the air guide channel 151 along the third direction Z. The first inclined plate 910 extends from the flat plate 930 towards the inner wall of the housing 100, and the first inclined plate 910 is inclined to the first direction X and the third direction Z. The first inclined plate 910 is inclined away from the first heat dissipation member 410 from near the flat plate 930 to far from the flat plate 930. When the cooling fan 510 conveys the air flow into the air guide space, the air flow is first diverted by the first inclined plate 910 to the space between the flat plate 930 and the first heat dissipation part 413. The second inclined plate 950 extends from the flat plate 930 towards the inner wall of the housing 100, and the second inclined plate 950 is inclined to the first direction X and the third direction Z. The second inclined plate 950 is inclined away from the first heat dissipation member 410 from near the flat plate 930 to far from the flat plate 930. After the air flow passes through the first heat dissipation sub-channel 415a, the second inclined plate 950 then guides the air flow to flow towards the second heat dissipation member 430, so that the air flow flows through the second heat dissipation sub-channel 435a.

[0239] The control unit 600 further includes two control buttons 650. The control buttons 650 are disposed on the second circuit board 630 and extend out of the housing 100 along the third direction Z. The third direction Z forms the thickness direction of the laser beauty device 001, which is convenient for the user to press the control buttons 650 when in use. By the user pressing the physical control buttons 650, the operation of the laser beauty device 001 can be controlled.

[0240] Understandably, the first implementation mode and the second implementation mode are not the only two implementation modes of the laser beauty device 001 of the present application. The implementation modes of the laser beauty device 001 of the present application can also be formed by combining the features in the first implementation mode and the features in the second implementation mode.

[0241] When the laser beauty device 001 provided by the present application is in use, it can have the following working process:

[0242] The user holds the housing 100 with the hand in the area between the air outlet 113 and the air inlet 111. The user turns on the laser beauty device 001, and the control unit 600 controls the cold source assembly 300, the laser light source assembly 200, and the capacitance sensor 800 to work. The outlet 101 of the laser beauty device 001 is driven to approach the user's skin. When the capacitance sensor 800 is electrically connected to the user's skin, the control unit 600 controls the cold source assembly 300, the laser light source assembly 200, and the cooling fan 510 to work, so that the laser light source assembly 200 emits laser light that can be emitted from the outlet 101, and the cold source assembly 300 provides cold air to the outlet 101, and the cooling fan 510 provides air flow to the first heat sink 410 and the second heat sink 430. The laser acts on the user's skin, thereby realizing skin beauty. The cold source assembly 300 cools the user's skin, improving the user's comfort and protecting the user's skin at the same time. When the capacitance sensor 800 is electrically disconnected from the user's skin, the control unit 600 controls the laser light source assembly 200 to stop working, and no longer emits laser light from the outlet 101, avoiding damage caused by laser irradiation to parts such as the eyes. However, the cooling fan 510 continues to operate for a preset time, so that the air flow continuously passes through the first heat sink 410 and the second heat sink 430, and cools the cold source assembly 300 and the laser light source assembly 200 to approximately room temperature.

[0243] This laser beauty device 001 can generate laser through the laser light source component 200, and the laser irradiates the user's skin through the light outlet 101 to achieve beauty treatment. Cold quantity is generated through the cold source component 300 to cool the skin of the user irradiated by the laser. The first heat dissipation member 410 and the second heat dissipation member 430 dissipate heat from the laser light source component 200 and the cold source component 300 respectively. The first heat dissipation member 410 and the second heat dissipation member 430 dissipate heat through fluid in sequence, so that the fluid first passes through the first heat dissipation member 410 to dissipate heat for the laser light source component 200 with relatively high heat dissipation demand, and then the fluid passes through the second heat dissipation member 430 to dissipate heat for the cold source component 300 with relatively low heat dissipation demand. Taking the heat dissipation of the laser light source component 200 as the main focus, the overall heat dissipation effect of the laser beauty device 001 is improved. The first heat dissipation member 410 and the second heat dissipation member 430 are arranged at intervals, so that heat is not directly transferred between the first heat dissipation member 410 and the second heat dissipation member 430. When the cold source component 300 dissipates heat, the heat diffused to the first heat dissipation member 410 by the second heat dissipation member 430 is reduced, thereby reducing the influence of the second heat dissipation member 430 on the heat dissipation effect of the first heat dissipation member 410.

[0244] As described above, it is only the specific implementation manner of the present application, but the protection scope of the present application is not limited thereto. Any change or replacement within the technical scope disclosed in the present application should be covered within the disclosure scope of the present application.
