Description

Technical Field

[0001] The present application relates to the technical field of hair removal equipment, and in particular to a skin treatment device. Background Art

[0002] Skin treatment devices such as hair removal devices and skin rejuvenation devices usually use light emitted by lamps to treat the skin, and use reflectors to reduce the light loss of the lamps. Since the lamps generate heat during operation, the skin treatment devices are also equipped with air cooling structures to cool the reflectors to achieve light cooling.

[0003] However, the air cooling structure of the related art blows the wind from one end of the lamp tube to the other end to dissipate the heat of the reflector during the cooling process, which causes the path of the wind flowing through the reflector to be too long and the heat dissipation effect to be poor.

[0035] In order to make those skilled in the art better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without making creative work are within the scope of protection of the present application.

[0036] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application.

[0037] See also Figure 1 and Figure 2 The embodiment of the present application provides a skin treatment device 100, which is a device that adjusts and improves the body and skin conditions according to the physiological functions of the human body. It has whitening, skin rejuvenation, freckle removal, wrinkle removal, hair removal and other effects. Based on optics, different effects can be achieved by using light of special wavelengths or different types of light to irradiate the skin. For example, currently, strong pulsed light, LED light, etc. are widely used.

[0038] In some embodiments, the skin treatment device 100 may be a hair removal device or a skin rejuvenation device.

[0039] In some embodiments, the skin treatment device 100 may include a housing 10, a lamp tube 21 and a reflector 22, and both the lamp tube 21 and the reflector 22 may be disposed in the housing 10. The housing 10 has a light outlet 11. The reflector 22 is disposed on the peripheral side of the lamp tube 21, and the lamp tube 21 is used to emit care light, so that the light is emitted from the opening 220 of the reflector 22 and emitted toward the skin to be treated through the light outlet 11. The reflector 22 helps to concentrate the light emitted from the lamp tube 21 to be emitted from the opening 220 of the reflector 22, thereby helping to reduce the light loss of the lamp tube 21.

[0040] In some embodiments, the light outlet 11 may be an opening structure such as a light outlet slot or a light outlet hole provided on the housing 10 .

[0041] In some embodiments, the light outlet 11 may also be formed by some light-transmitting areas on the housing 10. For example, at least part of the housing of the skin treatment device 100, such as the head housing, may be made of a light-transmitting material, and a light-shielding layer is provided in a local area of ​​the head housing to form the light outlet 11 where the light-shielding layer is not provided on the head housing.

[0042] In some embodiments, the housing 10 may include a front face 12 and a back face 13 facing each other, and the direction from the front face 12 to the back face 13 may be the thickness direction z or the width direction x of the skin treatment device 100. The light outlet 11 may be located at a side or other position connecting the front face 12 and the back face 13 in the housing 10, and the light outlet 11 may also be located at one end of the length direction y of the skin treatment device 100. Among them, the front face 12 may have a light display area, and the light display area may be used as a light-emitting area such as a power light and a function light. The front face 12 may also have a gear display area, and the gear display area may be used to display the working status, light intensity, etc. of the skin treatment device 100, and the gear display area may indicate different gears or intensities by displaying the number of lamp bodies.

[0043] In some embodiments, the skin treatment device 100 can be divided into different types according to the type of light generated by the lamp tube 21. For example, the lamp tube 21 can be used to generate intense pulsed light (IPL), which is an IPL light source (such as a xenon lamp), and the skin treatment device 100 is an intense pulsed light treatment device; for another example, the lamp tube 21 can be an LED light source component.

[0044] The present application mainly uses the lamp tube 21 as an IPL light source as an example for explanation. The light-emitting principle of this type of skin treatment device 100 is: the capacitor is connected to the power supply, and the transformer component boosts the voltage to charge the capacitor. When the capacitor is charged to a preset value and the controller receives a trigger signal, the electric energy in the capacitor is released, and the instantaneous voltage can reach several hundred volts, thereby stimulating the lamp tube 21 to instantly release strong pulsed light, thereby completing one light emission.

[0045] In some embodiments, the skin treatment device 100 may further include a heat sink 30 and a fan 40, both of which are disposed in the housing 10. The heat sink 30 may be used to connect with the reflector 22 to dissipate heat and cool the reflector 22, and then dissipate heat and cool the lamp 21. The fan 40 may be used to provide air cooling for the heat sink 30 to dissipate heat and cool the lamp; the fan 40 may also provide air cooling for the heat sink 30 and the reflector 22 to dissipate heat and cool the lamp; the fan 40 may also provide air cooling for the heat sink 30, the reflector 22 and the lamp 21 to dissipate heat and cool the lamp. Correspondingly, the housing 10 may further be provided with an air inlet 14 and an air outlet 15, and the fan 40 is suitable for driving air flow from the air inlet 14 to the air outlet 15, so as to accelerate the dissipation of excess heat in the housing 10 to the external environment.

[0046] In some embodiments, the fan 40 may be a centrifugal fan, the air inlet of the fan 40 may be located on one axial side of the fan 40 , and the air outlet 41 of the fan 40 may be located on one radial side of the fan 40 .

[0047] In some embodiments, the heat sink 30 includes a heat conducting portion 31 and a plurality of heat sinks 32. The heat conducting portion 31 is heat-conductingly connected to the peripheral side of the reflector 22 and avoids the opening 220 of the reflector 22. The plurality of heat sinks 32 are all connected to the side of the heat conducting portion 31 facing away from the reflector 22, so that the heat sink 30 can dissipate heat and cool the reflector 22 without blocking the light emitted by the lamp tube 21. The heat sink 30 can also transfer the heat of the reflector 22 to the heat sink 32 for heat dissipation. The plurality of heat sinks 32 help to increase the contact area between the heat sink 30 and the air, thereby improving the heat dissipation effect on the reflector 22.

[0048] In the present application, the term “plurality” means greater than or equal to two. For example, the number of the heat sinks 32 may be two, three, four, five, six, seven or other numbers.

[0049] In some embodiments, the fan 40 can be disposed on a side of the heat sink 32 away from the lamp tube 21 , thereby providing the skin treatment device 100 with more space for arranging the fan 40 and facilitating the air outlet 41 of the fan 40 to dissipate heat for the heat sink 32 .

[0050] In some embodiments, the heat conducting part 31 and the reflective element 22 can be directly bonded, or the heat conducting part 31 and the reflective element 22 can be indirectly bonded via a heat conducting medium such as thermal grease. Both bonding methods help to better transfer heat between the reflective element 22 and the heat conducting part 31.

[0051] In some embodiments, the heat conducting portion 31 and the reflective member 22 may be an integrally formed structure, which helps to reduce the number of parts of the skin treatment device 100 and saves assembly steps between the heat conducting portion 31 and the reflective member 22. The heat conducting portion 31 and the reflective member 22 may be integrally formed by a mold or other means.

[0052] In some embodiments, the heat conducting portion 31 and the reflective member 22 may be two independent structures, or it may be understood that the heat conducting portion 31 and the reflective member 22 are separate structures, and the heat conducting portion 31 and the reflective member 22 may be formed separately and then assembled into one.

[0053] In some embodiments, the heat sink 30 and the reflector 22 may be an integrally formed structure, which may also be understood as the heat conducting portion 31, the heat sink 32 and the reflector 22 being an integrally formed structure, which helps to reduce the number of parts of the skin treatment device 100 and may also save assembly steps between the heat sink 30 and the reflector 22. The heat sink 30 and the reflector 22 may be integrally formed by a mold or other means.

[0054] In some embodiments, the heat sink 30 and the reflector 22 may be two independent structures, or the heat sink 30 and the reflector 22 may be separate structures, and the heat sink 30 and the reflector 22 may be formed separately and then assembled together.

[0055] See also Figure 2 and Figure 3 In some embodiments, a plurality of heat sinks 32 may be spaced apart along the length direction of the lamp tube 21, and a heat sink 33 is provided between two adjacent heat sinks 32. The heat sink 33 has an inlet 331 and an outlet 332. The inlet 331 is arranged corresponding to the air outlet 41 of the fan 40, so that the wind sent out of the air outlet 41 of the fan 40 enters the heat sink 33 from the inlet 331 and then flows out from the outlet 332. In this way, the wind sent out of the air outlet 41 of the fan 40 can blow toward the heat sink 33 to dissipate heat for the heat sink 30, and the wind is blocked by two adjacent heat sinks 32, and will not flow toward other heat sinks 32 along the length direction of the lamp tube 21, shortening the flow path of the wind in the heat sink 30, helping to avoid the situation where the wind blows from one end of the lamp tube 21 to the other end, resulting in an excessively long flow path and heat accumulation at the rear end, thereby helping to improve the heat dissipation effect of the fan 40 on the heat sink 32. The length direction of the lamp tube 21 may be the thickness direction z or the width direction x of the skin treatment device 100.

[0056] In some embodiments, the air outlet 15 of the housing 10 may be opposite to the outlet 332 , so that the wind in the heat dissipation space 33 can be directly discharged from the air outlet 15 to the external environment.

[0057] In some embodiments, each heat sink 32 may have a first heat sink surface 321 and a second heat sink surface 322 facing each other. After the wind enters the heat sink gap 33, the wind may exchange heat with the first heat sink surface 321 of one of the heat sinks 32 to reduce the temperature of the first heat sink surface 321, and may also exchange heat with the second heat sink surface 322 of the other heat sink 32 to reduce the temperature of the second heat sink surface 322. The wind may also exchange heat with the surface of the heat conducting portion 31 facing away from the reflective element 22, thereby achieving heat dissipation and cooling for three different parts of the heat sink 30.

[0058] In some embodiments, the plurality of heat sinks 32 may be arranged in parallel or at an angle.

[0059] For example, at least two heat sinks 32 are arranged in parallel. In this way, during the process of manufacturing the heat sink 30 using a mold, it helps to simplify the mold structure of the heat sink 30, facilitates demoulding of the heat sink 32, and is more convenient for production and manufacturing. Among them, there can be two heat sinks 32 arranged in parallel, there can be three heat sinks 32 arranged parallel to each other, or all heat sinks 32 can be arranged parallel to each other. In the case where all heat sinks 32 are arranged parallel to each other, all heat sinks 32 can be arranged horizontally or approximately horizontally, so that the wind delivered by the fan 40 can flow to the opposite sides of each heat sink 32.

[0060] For another example, at least two heat sinks 32 are arranged at an angle. There may be two heat sinks 32 arranged at an angle, three heat sinks 32 arranged at an angle to each other, or any two adjacent heat sinks 32 arranged at an angle. The size of the angle can be determined according to actual needs, the number of heat sinks 32 or other conditions, for example, the angle can be 5 degrees, 10 degrees, 15 degrees or other angles.

[0061] For another example, the distance between any two adjacent heat sinks 32 may gradually increase in a direction away from the heat conducting portion 31 , which also helps to increase the spatial size of the heat dissipation gap 33 , allowing more air to enter the heat dissipation gap 33 and dissipate heat and cool the heat sink 30 .

[0062] In some embodiments, the first heat dissipation surface 321 and the second heat dissipation surface 322 of at least one heat dissipation fin 32 are at an angle. For example, in the same heat dissipation fin 32, the first heat dissipation surface 321 can be inclined in the direction of the second heat dissipation surface 322, or the first heat dissipation surface 321 can be inclined in the direction away from the second heat dissipation surface 322. For another example, in the same heat dissipation fin 32, the second heat dissipation surface 322 can be inclined in the direction of the first heat dissipation surface 321, or the second heat dissipation surface 322 can be inclined in the direction away from the first heat dissipation surface 321. In this way, the first heat dissipation surface 321 helps to increase the contact area with the air by being arranged in an inclined manner, and the second heat dissipation surface 322 also helps to increase the contact area with the air by being arranged in an inclined manner, which in turn helps to increase the contact area between the heat dissipation fin 32 and the air, thereby improving the heat dissipation effect of the heat dissipation fin 32.

[0063] The first heat dissipation surface 321 and the second heat dissipation surface 322 of one heat dissipation fin 32 may form an angle, or the first heat dissipation surface 321 and the second heat dissipation surface 322 of each heat dissipation fin 32 may form an angle.

[0064] In some embodiments, the thickness of at least one heat sink 32 gradually decreases in a direction away from the heat conducting portion 31 , which also helps to increase the contact area between the first heat dissipation surface 321 (and / or the second heat dissipation surface 322 ) of the heat sink 32 and the air, thereby improving the heat dissipation effect of the heat sink 32 .

[0065] The first heat dissipation surface 321 may be an inclined surface or a curved surface, and the curved surface may be a spherical surface or an arc surface. The second heat dissipation surface 322 may have the same or different shapes as the first heat dissipation surface 321. The second heat dissipation surface 322 may be an inclined surface or a curved surface, and the curved surface may be a spherical surface or an arc surface.

[0066] In some embodiments, the heat sink 32 may include a first heat sink 323 and a second heat sink 324. One end of the first heat sink 323 is connected to the heat conducting portion 31, and the other end extends toward the air outlet 41 of the fan 40. The second heat sink 324 is connected to at least one outlet 332 of the first heat sink 323. In this way, the wind flowing through the first heat sink 323 can dissipate heat and cool the first heat sink 323, and can flow through the second heat sink 324 on the outlet 332 side of the first heat sink 323 to dissipate heat and cool the second heat sink 324, which helps to increase the contact area between the heat sink 32 and the air.

[0067] In some embodiments, the first heat dissipation portion 323 may have a first outlet side 3321 and a second outlet side 3322, and the air outlet 15 of the shell 10 is opposite to the first outlet side 3321. The wind flowing through the first heat dissipation portion 323 can flow from the first outlet side 3321 to the air outlet 15, so that the wind can discharge the heat of the heat sink 32 to the external environment.

[0068] In some embodiments, the second heat dissipation portion 324 can be connected to the second outlet side 3322, and the second heat dissipation portion 324 is arranged close to the heat conducting portion 31. The side of the second heat dissipation portion 324 close to the heat conducting portion 31 is connected to the heat conducting portion 31, so that the heat of the heat conducting portion 31 can be better conducted to the second heat dissipation portion 324, so as to dissipate heat and cool the reflective element 22.

[0069] In some embodiments, the air outlet 41 of the fan 40 can blow air at an angle toward the second heat dissipation portion 324, which helps the air delivered by the air outlet 41 of the fan 40 to blow toward the first heat dissipation portion 323 and shorten the path of the air flowing from the first heat dissipation portion 323 to the second heat dissipation portion 324, thereby helping to improve the heat dissipation and cooling effect of the second heat dissipation portion 324.

[0070] In some embodiments, the skin treatment device 100 may further include a circuit board 70, the circuit board 70 is located in the housing 10, the circuit board 70 has a first side 71 and a second side 72 opposite to each other, the fan 40 is electrically connected to the circuit board 70, the first heat dissipation portion 323 and the fan 40 are both located on the first side 71, and the second heat dissipation portion 324 extends to the second side 72. In this way, it is helpful to reasonably distribute the positions of the first heat dissipation portion 323 and the second heat dissipation portion 324, and it is also helpful to increase the area of ​​the second heat dissipation portion 324, thereby helping to improve the heat dissipation effect of the second heat dissipation portion 324.

[0071] In some embodiments, the skin treatment device 100 may further include an air guide 103, which is located between the air outlet 41 of the fan 40 and the heat sink 32 and is inclined in a direction away from the air outlet 15, so that the air sent out from the air outlet 41 of the fan 40 flows toward the heat sink 32 from the side of the air guide 103 away from the air outlet 15. In this way, the air sent out from the air outlet 41 of the fan 40 can first be tilted downward to the heat sink 32, and then tilted upward to flow out of the heat sink 32, which helps to extend the flow path of the wind and improve the heat dissipation effect on the heat sink 32.

[0072] In some embodiments, the air outlet direction of the air outlet 41 of the fan 40 can be tilted toward the direction away from the air outlet 15 to blow toward the heat sink 32. This also helps the wind delivered by the air outlet 41 of the fan 40 to first tilt downward toward the heat sink 32 and then tilt upward out of the heat sink 32, which helps to extend the wind flow path and improve the heat dissipation effect on the heat sink 32.

[0073] See also Figure 1 and Figure 3 In some embodiments, the skin treatment device 100 may further include a cold compress component 60, which is disposed at the light outlet 11 for applying cold compress to the skin, thereby reducing or even eliminating the pain or burning sensation caused by the light acting on the skin.

[0074] In some embodiments, the cold compress assembly 60 can include a cold compress 61 and a refrigerator 62. The cooling surface of the refrigerator 62 is thermally connected to the cold compress 61. The refrigerator 62 can provide coldness for the cold compress 61. The cold compress 61 is arranged at the light outlet 11 for applying cold compress to the skin, so that the coldness generated by the refrigerator 62 can be transferred to the skin through the cold compress 61.

[0075] In some embodiments, the cold compress 61 is arranged at the light outlet 11. For example, the cold compress 61 can be installed on the light outlet 11, so that the cold compress 61 is located in the optical path of the light emitted by the lamp tube 21, so that the light emitted by the lamp tube 21 passes through the cold compress 61 and is emitted to the skin to be treated. In this case, the light emission and cold compress positions of the skin treatment device 100 are the same or partially overlap. For another example, the cold compress 61 can be arranged on the peripheral side or side of the light outlet 11, so that the cold compress 61 is outside the optical path of the light emitted by the lamp tube 21, and the light emitted by the lamp tube 21 does not pass through the cold compress 61. In this case, the light emission and cold compress positions of the skin treatment device 100 are not the same.

[0076] In some embodiments, the cold compress 61 may be sapphire. The cold compress 61 may be substantially in the shape of a block, a sheet, or other shapes.

[0077] In some embodiments, the cooler 62 may be a thermocouple cooler, which helps to simplify the structure of the cooler 62 and to miniaturize the cooler 62 , thereby facilitating the application of the cooler 62 in locations with limited space.

[0078] In some embodiments, the refrigerator 62 may include a semiconductor refrigeration sheet. The semiconductor refrigeration sheet utilizes the Peltier effect of semiconductor materials. When direct current passes through a thermocouple formed by two different semiconductor materials in series, heat can be absorbed and released at both ends of the thermocouple, respectively, to achieve the purpose of refrigeration. The semiconductor refrigeration sheet can be directly attached to the cold compress 61 to be thermally connected to the cold compress 61, or it can be indirectly connected to the cold compress 61 through a thermal conductive medium such as thermal grease, thereby cooling the cold compress 61.

[0079] In some embodiments, the refrigerator 62 may be a laser refrigerator, which also helps to simplify the structure of the refrigerator 62 and to miniaturize the refrigerator 62, making it easier to apply the refrigerator 62 to locations with limited space and making it less susceptible to electromagnetic influences.

[0080] In some embodiments, the skin treatment device 100 may further include a heat pipe 80 and a heat pipe heat sink 90, wherein the heat pipe 80 is thermally connected to the cold compress assembly 60, the heat pipe heat sink 90 is connected to the heat pipe 80, and the heat pipe heat sink 90 is located between the air outlet 41 of the fan 40 and the heat sink 30. In this way, the heat of the cold compress assembly 60 can be transferred to the heat pipe heat sink 90 via the heat pipe 80, and the wind sent out from the air outlet 41 of the fan 40 can dissipate heat and cool the heat pipe heat sink 90, and can also dissipate heat and cool the heat sink 30. Among them, the air guide 103 can be installed at the air outlet of the heat pipe heat sink 90, and it can also be understood that the air guide 103 is installed on the side of the heat pipe heat sink 90 facing the heat sink 30.

[0081] In some embodiments, the heat pipe 80 can be located on the side of the heat sink 30 facing the air outlet 15, and the heat pipe 80 can avoid the wind path from the outlet 332 to the air outlet 15. In this way, since the wind flows out from the outlet 332 of the heat sink 33 after the heat sink 30 dissipates heat, forming hot wind, the heat pipe 80 helps to reduce contact with the hot wind by avoiding the wind path from the outlet 332 to the air outlet 15, which helps to reduce the heat transfer to the heat pipe 80 and reduce the heat dissipation effect on the cold compress assembly 60.

[0082] In some embodiments, there is an exhaust cavity 101 between the heat sink 32 and the inner wall of the shell 10, and the exhaust cavity 101 is connected to the outlet 332 and the air outlet 15, so that the wind flowing out from the outlet 332 of the heat dissipation interval 33 can flow through the exhaust cavity 101 and can be discharged to the external environment from the air outlet 15.

[0083] In some embodiments, the distance between the air outlet 15 and the surface of the heat pipe heat sink 90 facing away from the air outlet 15 can be less than or equal to the distance between the air outlet 15 and the surface of the heat sink 32 facing the air outlet 15, so that part of the wind sent out from the air outlet 41 of the fan 40 is blown toward the heat pipe heat sink 90, and part is directly blown toward the heat sink 30. In this way, it is helpful to reduce the obstruction of the heat pipe heat sink 90 on the path of the wind sent out from the air outlet 41 of the fan 40 to the heat sink 30, so that the fan 40 can take into account the heat dissipation and cooling of the heat sink 30 and the heat pipe heat sink 90.

[0084] In some embodiments, the distance between the air outlet 15 and the surface of the heat pipe heat sink 90 facing away from the air outlet 15 is greater than the distance between the air outlet 15 and the surface of the heat sink 32 facing the air outlet 15, so that the wind sent out by the air outlet 41 of the fan 40 at least partially passes through the heat pipe heat sink 90 and blows toward the heat sink 30. In this way, the fan 40 is also helpful to dissipate heat and cool down the heat sink 30 and the heat pipe heat sink 90.

[0085] In some embodiments, the heat pipe 80 can surround the air path from the outlet 332 to the air outlet 15, so that the heat pipe 80 can better avoid the air path from the outlet 332 to the air outlet 15, which helps to reduce the contact between the heat pipe 80 and the hot air, helps to reduce the heat transferred to the heat pipe 80 and reduce the heat dissipation effect on the cold compress assembly 60.

[0086] In some embodiments, the heat pipe 80 may have a main section 81, a first section 82, and a second section 83, wherein the first section 82 and the second section 83 are respectively connected to both ends of the main section 81, the main section 81 is thermally connected to the cold compress assembly 60, the first section 82 and the second section 83 are both connected to the heat pipe radiator 90, and the projections of the first section 82 and the second section 83 along the direction of the air outlet 41 of the fan 40 toward the radiator 30 at least partially overlap. In this way, the contact areas of the first section 82 and the second section 83 with the heat pipe radiator 90 are respectively increased, thereby helping to improve the heat exchange efficiency between the heat pipe 80 and the heat pipe radiator 90.

[0087] In some embodiments, the main body segment 81 may include a first main body sub-segment 811, a second main body sub-segment 812, and a third main body sub-segment 813, wherein the first main body sub-segment 811 is thermally connected to the cold compress assembly 60, the second main body sub-segment 812 is connected to the first main body sub-segment 811 and the first segment 82, and the third main body sub-segment 813 is connected to the first main body sub-segment 811 and the second segment 83. In this way, by refining the structure of the main body segment 81, it is helpful to better disperse thermal stress, help avoid deformation or damage that may be caused by uneven thermal expansion, help enhance the mechanical stability and long-term reliability of the heat pipe 80 under frequent thermal cycle working conditions, and help extend the service life of the skin treatment device 100.

[0088] In some embodiments, the skin treatment device 100 may further include a bracket 50, the bracket 50 is located in the housing 10, the reflector 22 and the heat sink 30 are both located in the bracket 50, and the heat pipe 80 is located outside the bracket 50. In this way, the bracket 50 helps to fix and support the reflector 22 and the heat sink 30, and reduce vibration, displacement, etc. of the reflector 22 and the heat sink 30. In addition, it also helps to isolate the heat pipe 80 from the reflector 22 (or the heat sink 30), which not only helps to reduce the electrical conduction between the heat pipe 80 and the reflector 22 (or the heat sink 30), but also helps to reduce the thermal impact caused by each other.

[0089] In some embodiments, the bracket 50 may include a relative upper cover 53 and a lower cover 54, which are clamped together at the upper and lower sides of the heat conducting part 31, so that the position of the heat conducting part 31 is not easy to move, which helps to improve the stability of the internal structure of the skin treatment device 100.

[0090] In some embodiments, the upper cover 53 may include a first limiting member 531, which abuts against the side of the heat conducting portion 31 close to the first heat dissipation portion 323. The first limiting member 531 helps to limit the heat dissipation element 30, so that the heat dissipation element 30 is not easily moved out of position along the direction of the upper cover 53, which helps to improve the stability of the position of the heat dissipation element 30.

[0091] In some embodiments, the number of the first stopper 531 may be one or more. When the number of the first stopper 531 is one, the first stopper 531 may abut against the middle position or other position of the upper edge of the heat conducting portion 31; when the number of the first stopper 531 is multiple, the multiple first stoppers 531 may be distributed at intervals along the length direction of the heat conducting portion 31, and the multiple first stoppers 531 abutting against the upper edge of the heat conducting portion 31 together help to improve the stability of the heat conducting portion 31.

[0092] In some embodiments, the lower cover 54 may include a second limiting member 541, which abuts against the side of the second heat dissipation portion 324 facing away from the fan 40. The second limiting member 541 helps to limit the heat dissipation element 30, so that the heat dissipation element 30 is not easily moved out of position in a direction away from the fan 40, which helps to improve the stability of the position of the heat dissipation element 30.

[0093] In some embodiments, the number of the second stopper 541 may be one or more. When the number of the second stopper 541 is one, the second stopper 541 may abut against the middle position or other position of the lower edge of the heat conducting portion 31; when the number of the second stopper 541 is multiple, the multiple second stoppers 541 may be spaced and distributed along the length direction of the heat conducting portion 31, and the multiple second stoppers 541 abutting against the lower edge of the heat conducting portion 31 together help to improve the stability of the heat conducting portion 31.

[0094] In some embodiments, the bracket 50 may further include an insulating member 51, which is connected to the upper cover 53 and surrounds the air path from the outlet 332 to the air outlet 15, and the heat pipe 80 is located on the side of the upper cover 53 away from the reflector 22 and is placed on the outer ring side of the insulating member 51. In this way, when the skin treatment device 100 is working, the reflector 22 (or the heat sink 30) will carry high voltage electricity, and the insulating member 51 helps to isolate the heat pipe 80 from the reflector 22 (or the heat sink 30) to prevent electrical conduction, thereby helping to improve the safety of use.

[0095] In some embodiments, the reflector 22 is located outside the airflow path formed by the fan 40, or the heat conducting portion 31 separates the reflector 22 from the airflow path formed by the fan 40. In this way, both embodiments help reduce the airflow passing through the reflector 22, thereby helping to reduce the hair impurities mixed with the airflow entering the reflector 22, and then helping to reduce the hair impurities adhering to the lamp 21 and causing the luminous efficiency of the lamp 21 to decrease.

[0096] In some embodiments, the skin treatment device 100 may further include a windshield 102, which may be located at the end of the lamp tube 21, or located at the end of the reflector 22. In this way, the windshield 102 helps to block the airflow, helps to reduce the amount of hair impurities mixed in the airflow entering the reflector 22, and also helps to reduce light leakage.

[0097] In some embodiments, the surface of the wind shield 102 facing the inner surface of the reflector 22 may be provided with a reflective layer, which can enhance the reflectivity of the surface inside the reflector 22 to light, help reflect the light that is offset and divergent inside the reflector 22, improve the concentration of light and reduce light loss, and help improve the lighting efficiency of the lamp tube 21.

[0098] In some embodiments, the reflective layer may be sprayed onto the inner surface of the reflective element 22 , or may be plated onto the inner surface of the reflective element 22 .

[0099] In some embodiments, the wind shield 102 can be a heat-conducting insulating structure, so the wind shield 102 can dissipate the heat in the reflector 22 and conduct it to other places or other structures, and the wind shield 102 helps prevent the lamp tube 21 (or reflector 22) from being electrically connected to other structures.

[0100] In some embodiments, the wind shield 102 may be in contact with the lamp tube 21 and the reflector 22 , which helps the heat of the lamp tube 21 to be transferred to the wind shield 102 , and the heat of the wind shield 102 may also be transferred to the reflector 22 , thereby improving the heat dissipation effect on the lamp tube 21 .

[0101] In some embodiments, the wind shield 102 may be a heat conductive structure, for example, the wind shield 102 may be a metal member.
