Description

Technical Field

[0001] The present application relates to the technical field of skin treatment, 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 lampshades 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 lampshades to achieve cooling of the lamps. However, the air cooling structures of the related art blow wind from one end of the lamp to the other end to dissipate heat for the lampshades during the cooling process, resulting in a long path for the wind to flow through the lampshades, resulting in poor heat dissipation.

[0041] 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.

[0042] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application.

[0043] 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.

[0044] In some embodiments, the skin treatment device 100 may be a hair removal device or a skin rejuvenation device.

[0045] In some embodiments, the skin treatment device 100 may include a housing 10, a lamp tube 21 and a lampshade 22, and the lamp tube 21 and the lampshade 22 may be disposed in the housing 10. The housing 10 may have a light outlet 11. The lampshade 22 is disposed on 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 lampshade 22 and emitted to the skin to be treated through the light outlet 11. The lampshade 22 helps to concentrate the light emitted from the lamp tube 21 to be emitted from the opening 220 of the lampshade 22, thereby helping to reduce the light loss of the lamp tube 21.

[0046] 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 .

[0047] 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.

[0048] 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.

[0049] 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.

[0050] 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.

[0051] In some embodiments, the skin treatment device 100 may further include a heat sink 30 and a heat dissipation fan 40, both of which may be disposed in the housing 10. The heat sink 30 may be used to connect with the lampshade 22 to dissipate heat and cool the lampshade 22, and then dissipate heat and cool the lamp tube 21. The heat dissipation fan 40 may be used to provide air cooling for the heat sink 30 to dissipate heat and cool the lampshade 22; the heat dissipation fan 40 may also provide air cooling for the heat sink 30 and the lampshade 22 to dissipate heat and cool the lamp tube 21; the heat dissipation fan 40 may also provide air cooling for the heat sink 30, the lampshade 22 and the lamp tube 21 to dissipate heat and cool the lamp tube 21. Correspondingly, the housing 10 may further be provided with an air inlet 14 and an air outlet 15, so that the heat dissipation fan 40 can drive air flow from the air inlet 14 to the air outlet 15, thereby accelerating the dissipation of excess heat in the housing 10 to the external environment.

[0052] In some embodiments, the cooling fan 40 may be a centrifugal fan, the air inlet of the cooling fan 40 may be located on one axial side of the cooling fan 40 , and the air outlet 41 of the cooling fan 40 may be located on one radial side of the cooling fan 40 .

[0053] In some embodiments, the heat sink 30 may include a heat sink 31 and a plurality of heat sinks 32. The heat sink 31 is disposed on the lampshade 22 and avoids the opening 220 of the lampshade 22. The plurality of heat sinks 32 are all connected to the side of the heat sink 31 facing away from the lampshade 22, so that the heat sink 31 can dissipate heat and cool the lampshade 22 without blocking the light emitted by the lamp tube 21. The heat sink 31 can also transfer the heat of the lampshade 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 helping to improve the heat dissipation effect on the lampshade 22.

[0054] 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.

[0055] In some embodiments, the heat dissipation cover 31 and the lampshade 22 can be directly bonded together, or the heat dissipation cover 31 and the lampshade 22 can be indirectly bonded together through a heat conductive medium such as thermal grease. Both bonding methods help to better transfer heat between the lampshade 22 and the heat dissipation cover 31.

[0056] In some embodiments, the heat dissipation cover 31 and the lampshade 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 dissipation cover 31 and the lampshade 22. The heat dissipation cover 31 and the lampshade 22 may be integrally formed by a mold or other means.

[0057] In some embodiments, the heat dissipation cover 31 and the lampshade 22 may also be two independent structures, or it may be understood that the heat dissipation cover 31 and the lampshade 22 are separate structures, and the heat dissipation cover 31 and the lampshade 22 may be formed separately and then assembled into one.

[0058] In some embodiments, the heat sink 30 and the lampshade 22 may be an integrally formed structure, which may also be understood as the heat sink 31, the heat sink 32 and the lampshade 22 being an integrally formed structure, which helps to reduce the number of parts of the skin treatment device 100 and also saves assembly steps between the heat sink 30 and the lampshade 22. The heat sink 30 and the lampshade 22 may be integrally formed by a mold or other means.

[0059] In some embodiments, the heat sink 30 and the lampshade 22 may be two independent structures, or the heat sink 30 and the lampshade 22 may be separate structures, and the heat sink 30 and the lampshade 22 may be formed separately and then assembled together.

[0060] See also Figures 2 to 4In some embodiments, a plurality of heat sinks 32 may be distributed at intervals around the circumference of the heat sink 31, each heat sink 32 extends along the length direction of the lamp tube 21, a heat sink 33 is provided between two adjacent heat sinks 32, and heat outlets 330 are provided at both ends of the heat sink 33. The ends of the heat sink 32 are opposite to the air outlet 41 of the heat dissipation fan 40, so that the air sent out from the air outlet 41 of the heat dissipation fan 40 enters the heat sink 33 and flows out from the heat outlets 330 at both ends of the heat sink 33. In this way, the wind is helped to blow from the position between the two ends of the heat sink 32 to the two ends. For example, the wind blowing to the middle of the heat sink 32 can be divided into two branches, one of which blows to the left end along the length direction of the heat sink 32, and the other blows to the right end along the length direction of the heat sink 32, shortening the flow path of the wind in the heat sink 32, helping to avoid the situation where the wind blows from one end of the heat sink 32 to the other end, resulting in an excessively long flow path and heat accumulation at the rear end of the flow path, thereby helping to improve the heat dissipation effect of the heat sink 32 by the heat dissipation fan 40. The length direction of the heat sink 32 can be the thickness direction z or the width direction x of the skin treatment device 100.

[0061] 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 exchanges 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 exchanges 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 can also exchange heat with the surface of the heat sink 31 facing away from the lampshade 22, thereby achieving heat dissipation and cooling for three different parts of the heat sink 30.

[0062] In some embodiments, the plurality of heat sinks 32 may be arranged in parallel or at an angle.

[0063] For example Figure 4 As shown, at least two heat sinks 32 are arranged in parallel. In this way, in 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 sent by the heat dissipation fan 40 can flow to the opposite sides of each heat sink 32.

[0064] Another example Figure 5As shown, 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.

[0065] Another example Figure 5 As shown, a plurality of heat sinks 32 may be arranged radially with the heat sink 31 as the center, which helps to increase the spatial size of the heat sink space 33 , allowing more air to enter the heat sink space 33 and dissipate heat and cool the heat sink 30 .

[0066] Another example Figure 5 As shown, the distance between any two adjacent heat sinks 32 can be gradually increased in the direction away from the heat sink 31 , which also helps to increase the spatial size of the heat sink 33 , allowing more air to enter the heat sink 33 and dissipate heat and cool the heat sink 30 .

[0067] See also Figure 6 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 obliquely, and the second heat dissipation surface 322 also helps to increase the contact area with the air by being arranged obliquely, 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.

[0068] 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.

[0069] See also Figure 6 In some embodiments, the thickness of at least one heat sink 32 gradually decreases in a direction away from the heat sink 31 . This also helps to increase the contact area between the first heat sink surface 321 (and / or the second heat sink surface 322 ) of the heat sink 32 and the air, thereby improving the heat dissipation effect of the heat sink 32 .

[0070] 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.

[0071] See also Figure 2 and Figure 7 In some embodiments, the skin treatment device 100 may further include a bracket 50, which is located in the housing 10. The bracket 50 has a first heat dissipation channel 51, which is opposite to the air outlet 41 of the heat dissipation fan 40. The lampshade 22 and the heat dissipation element 30 are both located in the first heat dissipation channel 51, so that the wind sent out from the air outlet 41 of the heat dissipation fan 40 can be blown into the first heat dissipation channel 51 to dissipate heat and cool the lampshade 22 and the heat dissipation element 30. The lamp tube 21 and the lampshade 22 may also be located in the bracket 50, for example, the lamp tube 21 and the lampshade 22 may be located on the side of the bracket 50 away from the air outlet 41 of the heat dissipation fan 40.

[0072] In some embodiments, when multiple heat sinks 32 are radially arranged with the heat sink cover 31 as the center, the height of the heat sink 32 protruding from the heat sink cover 31 near the inner wall of the bracket 50 can be less than the height of the heat sink 32 protruding from the heat sink cover 31 away from the inner wall of the bracket 50, which helps to reduce the abutment or interference between the heat sink 32 near the inner wall of the bracket 50 and the inner wall of the bracket 50, and facilitates the wind delivered by the cooling fan 40 to blow into the gap between the heat sink 32 closest to the inner wall of the bracket 50 and the inner wall of the bracket 50 to dissipate heat and cool the heat sink 30.

[0073] In some embodiments, the bracket 50 may include a guide surface 540, which can extend from the air outlet 41 of the cooling fan 40 toward the heat sink 32. The height of the guide surface 540 can gradually decrease from the air outlet 41 of the cooling fan 40 toward the heat sink 32, which helps the guide surface 540 to better guide the wind sent out by the cooling fan 40 to blow toward the heat sink 32.

[0074] The guide surface 540 may be an inclined surface or a curved surface, and the curved surface may be a spherical surface or an arc surface.

[0075] In some embodiments, the bracket 50 may also include an anti-spoiler member 52, which may be protruding from the guide surface 540 and located between the air outlet 41 of the cooling fan 40 and the heat sink 32. The anti-spoiler member 52 helps to reduce the turbulence caused by the wind delivered by the cooling fan 40 in the bracket 50, thereby helping the wind delivered from the air outlet 41 of the cooling fan 40 to flow more directly to the heat sink 32.

[0076] In some embodiments, the anti-spoiler 52 and the heat sink 32 may abut against each other or have a gap, so that the anti-spoiler 52 can limit the heat sink 30, so that the heat sink 30 is not easily moved away from the position in the direction of the heat sink fan 40, which helps to improve the stability of the position of the heat sink 30. Among them, the gap between the anti-spoiler 52 and the heat sink 32 can be adjusted according to the size of the actual structure, so that the heat sink 30 will not be easily deviated from the position due to the excessive gap due to external vibration.

[0077] In some embodiments, when the anti-spoiler 52 abuts against the heat sink 32 , the anti-spoiler 52 may abut against one or more heat sinks 32 .

[0078] In some embodiments, the anti-spoiler 52 and the heat sink 32 may be mutually locked.

[0079] For example, see Figure 8 The heat sink 32 may be provided with a slot 320, and the anti-spoiler 52 may be mounted in the slot 320, so that the heat sink 30 is not easily moved away from the position in the direction of the cooling fan 40, the length direction of the heat sink 32, etc., which helps to improve the stability of the position of the heat sink 30. The anti-spoiler 52 may be mounted in the slot 320 of a corresponding heat sink 32, or the anti-spoiler 52 may be mounted in the slots 320 of multiple heat sinks 32.

[0080] For another example, the anti-spoiler 52 may be provided with a slot, and the heat sink 32 may be locked in the slot, which also helps to prevent the heat sink 30 from easily moving out of position in the direction of the heat sink fan 40, in the length direction of the heat sink 32, etc., thereby improving the stability of the position of the heat sink 30. The slot of the anti-spoiler 52 may be used to lock with a corresponding heat sink 32, and the slot of the anti-spoiler 52 may also be used to lock with multiple heat sinks 32.

[0081] In some embodiments, the number of the anti-spoiler 52 may be one or more. A plurality of anti-spoiler 52 may be distributed at intervals on the guide surface 540 , for example, a plurality of anti-spoiler 52 may be distributed at intervals along the length direction of the heat sink 32 .

[0082] See also Figure 7 In some embodiments, the bracket 50 may include an upper limit wall 53 and a lower limit wall 54 relative to each other, and the upper edge 310 of the heat dissipation cover 31 may abut against the upper limit wall 53, for example, the upper edge 310 of the heat dissipation cover 31 may abut against the portion of the upper limit wall 53 away from the heat dissipation fan 40. The lower edge 311 of the heat dissipation cover 31 abuts against the lower limit wall 54, for example, the lower edge 311 of the heat dissipation cover 31 may abut against the portion of the lower limit wall 54 away from the heat dissipation fan 40. In this way, it is helpful to realize that the bracket 50 limits the heat dissipation cover 31. Among them, the guide surface 540 may be the inner wall of the lower limit wall 54.

[0083] In some embodiments, the direction from the upper limiting wall 53 to the lower limiting wall 54 may be the thickness direction z or the width direction x of the skin treatment device 100 .

[0084] In some embodiments, at least one of the upper limiting wall 53 and the lower limiting wall 54 may be provided with a first limiting member 55. The first limiting member 55 may be located on the side of the upper edge 310 and the lower edge 311 of the heat dissipation cover 31 away from the heat dissipation fan 40, and abut against the upper edge 310 and the lower edge 311 of the heat dissipation cover 31. The first limiting member 55 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 heat dissipation fan 40, which helps to improve the stability of the position of the heat dissipation element 30.

[0085] For example, the upper limit wall 53 is provided with a first stopper 55, which is located on the side of the upper edge 310 of the heat dissipation cover 31 away from the heat dissipation fan 40 and abuts against the upper edge 310 of the heat dissipation cover 31. The number of the first stopper 55 provided on the upper limit wall 53 can be one or more; in the case where the upper limit wall 53 is provided with a first stopper 55, the first stopper 55 can abut against the middle position or other positions of the upper edge 310 of the heat dissipation cover 31; in the case where the upper limit wall 53 is provided with multiple first stoppers 55, the multiple first stoppers 55 can be distributed at intervals along the length direction of the heat dissipation cover 31, and the multiple first stoppers 55 abut against the upper edge 310 of the heat dissipation cover 31 together to help improve the stability of the heat dissipation cover 31.

[0086] In addition, the first stopper 55 also helps to increase the wall thickness of the upper limit wall 53 at the first stopper 55, thereby helping to improve the strength and rigidity of the structure of the upper limit wall 53 around the first stopper 55 without increasing the overall thickness of the upper limit wall 53. The first stopper 55 and the upper limit wall 53 can be an integrally formed structure.

[0087] For another example, the lower limiting wall 54 is provided with a first limiting member 55, which is located at the side of the lower edge 311 of the heat dissipation cover 31 away from the heat dissipation fan 40 and abuts against the lower edge 311 of the heat dissipation cover 31. The number of the first limiting members 55 provided on the lower limiting wall 54 can be one or more; in the case where the lower limiting wall 54 is provided with a first limiting member 55, the first limiting member 55 can abut against the middle position or other positions of the lower edge 311 of the heat dissipation cover 31; in the case where the lower limiting wall 54 is provided with multiple first limiting members 55, the multiple first limiting members 55 can be distributed at intervals along the length direction of the heat dissipation cover 31, and the multiple first limiting members 55 abut against the lower edge 311 of the heat dissipation cover 31 together to help improve the stability of limiting the heat dissipation cover 31.

[0088] In addition, the first stopper 55 also helps to increase the wall thickness of the lower stopper 54 at the first stopper 55, thereby helping to improve the strength and rigidity of the structure of the lower stopper 54 around the first stopper 55 without increasing the overall thickness of the lower stopper 54. The first stopper 55 and the lower stopper 54 can be an integrally formed structure.

[0089] For another example, the upper limiting wall 53 and the lower limiting wall 54 are both provided with a first limiting member 55 , which helps to improve the stability of limiting the upper edge 310 and the lower edge 311 of the heat dissipation cover 31 .

[0090] See also Figure 7 and Fig. 9 In some embodiments, at least one of the upper limit wall 53 and the lower limit wall 54 may be provided with a second limit member 56. For example, the upper limit wall 53 is provided with a second limit member 56. For another example, the lower limit wall 54 is provided with a second limit member 56. For another example, both the upper limit wall 53 and the lower limit wall 54 are provided with a second limit member 56.

[0091] In some embodiments, the second stopper 56 protruding from the upper limit wall 53 can abut against the heat sink 32 closest to the upper limit wall 53, and the second stopper 56 helps to limit the heat sink 30, so that the heat sink 30 is not easy to move away from the position along the direction of the upper limit wall 53, which helps to improve the stability of the position of the heat sink 30. Among them, the number of the second stopper 56 protruding from the upper limit wall 53 can be one or more; in the case where the upper limit wall 53 protrudes with a second stopper 56, the second stopper 56 can abut against the middle position or other position of the heat sink 32 closest to the upper limit wall 53; in the case where the upper limit wall 53 protrudes with multiple second stoppers 56, the multiple second stoppers 56 can be spaced and distributed along the length direction of the heat sink 31, and the multiple second stoppers 56 abut against the heat sink 32 closest to the upper limit wall 53 together, which helps to improve the stability of limiting the heat sink 32.

[0092] In addition, the second stopper 56 also helps to increase the wall thickness of the upper limit wall 53 at the second stopper 56, thereby helping to improve the strength and rigidity of the structure around the second stopper 56 in the upper limit wall 53 without increasing the overall thickness of the upper limit wall 53. The second stopper 56 and the upper limit wall 53 can be an integrally formed structure.

[0093] In some embodiments, when the second limit member 56 protruding from the upper limit wall 53 abuts against the heat sink 32 closest to the upper limit wall 53, a wind gap 501 may be provided between the second limit member 56 and the upper edge 310 of the heat sink 31, so as to facilitate the heat dissipation of the heat sink 30 to flow out of the space between the heat sink 31 and the upper limit wall 53 through the wind gap 501.

[0094] In some embodiments, the second stopper 56 protruding from the lower stopper wall 54 can abut against the heat sink 32 closest to the lower stopper wall 54, and the second stopper 56 helps to limit the heat sink 30, so that the heat sink 30 is not easy to move away from the position along the direction of the lower stopper wall 54, which helps to improve the stability of the position of the heat sink 30. Among them, the number of the second stopper 56 protruding from the lower stopper wall 54 can be one or more; in the case where the lower stopper wall 54 protrudes with one second stopper 56, the second stopper 56 can abut against the middle position or other position of the heat sink 32 closest to the lower stopper wall 54; in the case where the lower stopper wall 54 protrudes with multiple second stoppers 56, the multiple second stoppers 56 can be spaced and distributed along the length direction of the heat sink 31, and the multiple second stoppers 56 abut against the heat sink 32 closest to the lower stopper wall 54 together, which helps to improve the stability of limiting the heat sink 32.

[0095] In addition, the second stopper 56 also helps to increase the wall thickness of the lower stopper 54 at the second stopper 56, thereby helping to improve the strength and rigidity of the structure around the second stopper 56 in the lower stopper 54 without increasing the overall thickness of the lower stopper 54. The second stopper 56 and the lower stopper 54 can be an integrally formed structure.

[0096] In some embodiments, when the second limiting member 56 protruding from the lower limiting wall 54 abuts against the heat sink 32 closest to the lower limiting wall 54, a wind gap 501 may be provided between the second limiting member 56 and the lower edge 311 of the heat dissipation cover 31, so as to facilitate the wind between the heat dissipation cover 31 and the lower limiting wall 54 to flow out of the space between the heat dissipation cover 31 and the lower limiting wall 54 through the wind gap 501 after dissipating heat and cooling the heat sink 30.

[0097] In some embodiments, at least one of the upper limit wall 53 and the lower limit wall 54 may be provided with a third limiter 57 and a fourth limiter 58. For example, the upper limit wall 53 is provided with a third limiter 57 and a fourth limiter 58. For another example, the lower limit wall 54 is provided with a third limiter 57 and a fourth limiter 58. For another example, both the upper limit wall 53 and the lower limit wall 54 are provided with a third limiter 57 and a fourth limiter 58. The third limiter 57 and the fourth limiter 58 may be respectively abutted against the two ends of the length direction of the heat sink 32, and the third limiter 57 and the fourth limiter 58 help to limit the heat sink 30, so that the heat sink 30 is not easy to move out of position along the length direction of the heat sink 32, which helps to improve the stability of the position of the heat sink 30.

[0098] In some embodiments, the third stopper 57 protruding from the upper limit wall 53 can abut against the heat sink 32 closest to the upper limit wall 53, which helps to reduce the obstruction of the heat dissipation port 330 of the heat dissipation element 30 caused by the third stopper 57, so that the wind flowing through the heat dissipation interval 33 can flow out from the heat dissipation port 330 after dissipating heat and cooling the heat dissipation element 30. The number of the third stopper 57 protruding from the upper limit wall 53 can be one or more.

[0099] In addition, the third stopper 57 also helps to increase the wall thickness of the upper limit wall 53 at the third stopper 57, thereby helping to improve the strength and rigidity of the structure around the third stopper 57 in the upper limit wall 53 without increasing the overall thickness of the upper limit wall 53. The third stopper 57 and the upper limit wall 53 can be an integrally formed structure.

[0100] In some embodiments, the third stopper 57 protruding from the lower stopper wall 54 can abut against the heat sink 32 closest to the lower stopper wall 54, which helps to reduce the obstruction of the heat dissipation port 330 of the heat dissipation element 30 caused by the third stopper 57, so that the wind flowing through the heat dissipation interval 33 can flow out from the heat dissipation port 330 after dissipating heat and cooling the heat dissipation element 30. The number of the third stopper 57 protruding from the lower stopper wall 54 can be one or more.

[0101] In addition, the third limiting member 57 also helps to increase the wall thickness of the lower limiting wall 54 at the third limiting member 57, thereby helping to improve the strength and rigidity of the structure around the third limiting member 57 in the lower limiting wall 54 without increasing the overall thickness of the lower limiting wall 54. The third limiting member 57 and the lower limiting wall 54 can be an integrally formed structure.

[0102] In some embodiments, the fourth stopper 58 protruding from the upper limit wall 53 can abut against the heat sink 32 closest to the upper limit wall 53, which helps to reduce the obstruction of the heat dissipation port 330 of the heat dissipation element 30 caused by the fourth stopper 58, so that the wind flowing through the heat dissipation interval 33 can flow out from the heat dissipation port 330 after dissipating heat and cooling the heat dissipation element 30. The number of the fourth stopper 58 protruding from the upper limit wall 53 can be one or more.

[0103] In addition, the fourth limiting member 58 also helps to increase the wall thickness of the upper limit wall 53 at the fourth limiting member 58, thereby helping to improve the strength and rigidity of the structure around the fourth limiting member 58 in the upper limit wall 53 without increasing the overall thickness of the upper limit wall 53. The fourth limiting member 58 and the upper limit wall 53 can be an integrally formed structure.

[0104] In some embodiments, the fourth stopper 58 protruding from the lower stopper wall 54 can abut against the heat sink 32 closest to the lower stopper wall 54, which helps to reduce the obstruction of the heat dissipation port 330 of the heat dissipation element 30 caused by the fourth stopper 58, so that the wind flowing through the heat dissipation interval 33 can flow out from the heat dissipation port 330 after dissipating heat and cooling the heat dissipation element 30. The number of the fourth stopper 58 protruding from the lower stopper wall 54 can be one or more.

[0105] In addition, the fourth limiting member 58 also helps to increase the wall thickness of the lower limiting wall 54 at the fourth limiting member 58, thereby helping to improve the strength and rigidity of the structure around the fourth limiting member 58 in the lower limiting wall 54 without increasing the overall thickness of the lower limiting wall 54. The fourth limiting member 58 and the lower limiting wall 54 can be an integrally formed structure.

[0106] In some embodiments, the distance between at least one of the upper limit wall 53 and the lower limit wall 54 and the outer peripheral side of the heat dissipation cover 31 can be gradually increased along the direction from the heat dissipation cover 31 to the heat dissipation fan 40. For example, the distance between the upper limit wall 53 and the outer peripheral side of the heat dissipation cover 31 is gradually increased along the direction from the heat dissipation cover 31 to the heat dissipation fan 40. For another example, the distance between the lower limit wall 54 and the outer peripheral side of the heat dissipation cover 31 is gradually increased along the direction from the heat dissipation cover 31 to the heat dissipation fan 40. For another example, the distance between both the upper limit wall 53 and the lower limit wall 54 and the outer peripheral side of the heat dissipation cover 31 is gradually increased along the direction from the heat dissipation cover 31 to the heat dissipation fan 40. In this way, the above examples are helpful to increase the contact area between the heat dissipation cover 31 and the air, and also help to increase the size of the wind gap 501, thereby helping to improve the heat dissipation effect of the heat dissipation cover 31.

[0107] The outer peripheral surface of the heat dissipation cover 31 may be an inclined surface or a curved surface, and the curved surface may be an arc surface or a spherical surface.

[0108] See also Figure 2 and Figure 7 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.

[0109] 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.

[0110] 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.

[0111] 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.

[0112] 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.

[0113] 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.

[0114] 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.

[0115] In some embodiments, the skin treatment device 100 may further include a temperature averaging plate 71 and a temperature averaging plate heat sink 72, the temperature averaging plate 71 is thermally connected to the cold compress assembly 60, and the temperature averaging plate heat sink 72 is connected to the temperature averaging plate 71, so that the heat of the cold compress assembly 60 can be transferred to the temperature averaging plate 71, and can be transferred from the temperature averaging plate 71 to the temperature averaging plate heat sink 72, thereby realizing heat dissipation for the cold compress assembly 60. The temperature averaging plate 71 can be thermally connected to the heating surface of the refrigerator 62 of the cold compress assembly 60.

[0116] In some embodiments, the temperature homogenizer 71 may be a vacuum chamber (VC) temperature homogenizer, a copper alloy temperature homogenizer, a stainless steel temperature homogenizer, a graphene temperature homogenizer, or other structures.

[0117] In some embodiments, the vapor chamber heat sink 72 may be a heat sink fin or other heat dissipation structure.

[0118] In some embodiments, the bracket 50 may also be provided with a second heat dissipation channel 59 connected to the air outlet 15 of the shell 10, and the second heat dissipation channel 59 is located on the upper side of the first heat dissipation channel 51, and the second heat dissipation channel 59 corresponds to the air outlet 41 of the cooling fan 40, the temperature equalizing plate 71 may be at least partially located in the second heat dissipation channel 59, and the temperature equalizing plate heat sink 72 may be located in the second heat dissipation channel 59, then the wind delivered from the air outlet 41 of the cooling fan 40 can be blown toward the temperature equalizing plate 71 and the temperature equalizing plate heat sink 72, and can blow the heat from the second heat dissipation channel 59 toward the air outlet 15, which not only helps to provide a wind-cooled heat dissipation effect for the temperature equalizing plate 71 and the temperature equalizing plate heat sink 72, but also helps to dissipate the excess heat in the second heat dissipation channel 59 to the external environment. Among them, the second heat dissipation channel 59 is located on the upper side of the first heat dissipation channel 51. It can be understood that the second heat dissipation channel 59 and the first heat dissipation channel 51 can be distributed along the thickness direction z or the width direction x of the skin treatment device 100. It can also be understood that the direction of the second heat dissipation channel 59 toward the first heat dissipation channel 51 is the direction of the upper limit wall 53 toward the lower limit wall 54.

[0119] In some embodiments, the temperature vaporizer 71 may be partially or completely located in the second heat dissipation channel 59. When the temperature vaporizer 71 is partially located in the second heat dissipation channel 59, another part of the temperature vaporizer 71 may be located in the first heat dissipation channel 51 or at other locations.

[0120] In some embodiments, the bracket 50 may include a partition plate 530 for separating the first heat dissipation channel 51 from the second heat dissipation channel 59, and the temperature averaging plate 71 may be supported on a side of the partition plate 530 away from the first heat dissipation channel 51. The partition plate 530 helps to separate the temperature averaging plate 71 from the lampshade 22 (when the lamp tube 21 is working, the lampshade 22 will have a high voltage), so that the distance between the exposed part of the temperature averaging plate 71 and the lampshade 22 is greater than the safe distance, which helps to prevent the lampshade 22 from leaking electricity to the temperature averaging plate 71, thereby helping to improve the reliability and safety of the skin treatment device 100.

[0121] The first heat dissipation channel 51 and the second heat dissipation channel 59 may be connected or disconnected at the partition plate 530. The partition plate 530 may be a part of the upper limit wall 53; or, the partition plate 530 and the upper limit wall 53 may be an integrally formed structure; or, the partition plate 530 and the upper limit wall 53 may be two independent structures, or the partition plate 530 and the upper limit wall 53 may be separate structures, and the partition plate 530 and the upper limit wall 53 may be formed separately and then assembled into one.

[0122] See also Figures 8 to 10 In some embodiments, the bracket 50 may be provided with a first turning air duct 502, which may be located at one end in the length direction of the heat sink 32. The first turning air duct 502 is connected to the first heat dissipation channel 51 and the second heat dissipation channel 59, which helps the wind at the heat dissipation port 330 of the heat sink 30 to flow from the first turning air duct 502 to the second heat dissipation channel 59, and can flow to the air outlet 15 through the second heat dissipation channel 59 to discharge the heat to the external environment.

[0123] In addition, since the air outlet 41 of the cooling fan 40 corresponds to the first cooling channel 51 and the second cooling channel 59 at the same time, the wind directly blown from the air outlet 41 of the cooling fan 40 to the first cooling channel 51 is used as the first airflow, and the wind directly blown from the air outlet 41 of the cooling fan 40 to the second cooling channel 59 is used as the second airflow. Since the first airflow passes through multiple structures in the first cooling channel 51 and then enters the second cooling channel 59, the flow rate of the first airflow will be lower than the flow rate of the second airflow, so that the first airflow and the second airflow will produce a Bernoulli effect in the second cooling channel 59 due to the flow rate difference, thereby driving the first airflow to flow faster, for example, helping to speed up the first airflow in the cooling gap 33 of the heat sink 32 to flow to the first turning air duct 502, and for another example, helping to speed up the first airflow in the first turning air duct 502 to flow to the second cooling channel 59, which helps to improve the heat dissipation effect of the heat sink 30.

[0124] In some embodiments, the connection point between the first turning air duct 502 and the first heat dissipation channel 51 can be set corresponding to the heat dissipation port 330 at one end of the heat dissipation interval 33, so that the wind at the heat dissipation port 330 can flow directly from the first heat dissipation channel 51 to the first turning air duct 502.

[0125] In some embodiments, the bracket 50 may be provided with a second turning air duct 503, and the second turning air duct 503 may be located at the other end in the length direction of the heat sink 32. The second turning air duct 503 is connected to the first heat dissipation channel 51 and the second heat dissipation channel 59, which helps the wind at the heat dissipation port 330 of the heat sink 30 to flow from the second turning air duct 503 to the second heat dissipation channel 59, and can flow to the air outlet 15 through the second heat dissipation channel 59 to discharge the heat to the external environment.

[0126] In addition, the Bernoulli effect as described in the above embodiment helps to accelerate the flow of the first airflow in the heat dissipation gap 33 of the heat sink 32 to the second turning air duct 503, and also helps to accelerate the flow of the first airflow in the second turning air duct 503 to the second heat dissipation channel 59, which helps to improve the heat dissipation effect of the heat sink 30.

[0127] See also Figure 2 In some embodiments, the first heat dissipation channel 51 has a first air inlet 510 opposite to the air outlet 41 of the heat dissipation fan 40, and the second heat dissipation channel 59 has a second air inlet 590 opposite to the air outlet 41 of the heat dissipation fan 40. The area of ​​the second air inlet 590 can be larger than the area of ​​the first air inlet 510, which helps to increase the flow velocity difference between the first airflow and the second airflow in the second heat dissipation channel 59, and then helps to improve the heat dissipation effect on the heat sink 30 and the temperature dispersion plate heat sink 72.

[0128] See also Figures 8 to 10 In some embodiments, the connection between the second turning air duct 503 and the first heat dissipation channel 51 can be set corresponding to the heat dissipation port 330 at the other end of the heat dissipation interval 33, so that the wind located at the heat dissipation port 330 can flow directly from the first heat dissipation channel 51 to the second turning air duct 503.

[0129] In some embodiments, the second heat dissipation channel 59 has a mixing chamber 591 located between the temperature homogenizer heat sink 72 and the inner wall of the shell 10, the mixing chamber 591 is connected to the air outlet 15, and the first turning air duct 502 and the second turning air duct 503 are respectively connected to the two sides of the mixing chamber 591, which helps the first airflow and the second airflow to mix in the mixing chamber 591 and be discharged to the external environment through the air outlet 15 of the shell 10.

[0130] In some embodiments, the air outlet 15 of the housing 10 may be arranged corresponding to the second heat dissipation channel 59 , so that the wind in the second heat dissipation channel 59 can be directly discharged from the air outlet 15 to the external environment.

[0131] In some embodiments, the air outlet 15 of the housing 10 may be located on the back side 13 , or on the front side 12 , or both the back side 13 and the front side 12 may be provided with the air outlet 15 .
