[0074] SUMMARY OF THE DISCLOSURE In order to solve the problem that the length of the heat conductive member of the skin treatment device in the prior art is relatively long, which affects the heat dissipation efficiency of the heat dissipation fin assembly, the present application provides a skin treatment device.

[0075] As shown in Figs. 1 to 59, the skin treatment device includes a casing assembly 100, a light emitting assembly 200, a cold pack assembly 300, and a heat dissipation assembly 400. The casing assembly 100 has a receiving chamber and a light outlet 11 which are in communication with each other. The light emitting assembly 200 is installed in the receiving chamber, and light generated from the light emitting assembly 200 is irradiated to the skin to be treated after passing through the light outlet 11. The cold pack assembly 300 is installed in the casing assembly 100 and positioned at the light outlet 11, and is used to cool the skin to be treated or the skin near the skin to be treated. The heat dissipation assembly 400 includes a heat conductive structure 410 and a heat dissipation fin assembly 420, the heat conductive structure 410 includes a first heat conductive portion 411 and a second heat conductive portion 412 connected to each other, the cold pack assembly 300 is thermally connected to the first heat conductive portion 411, the light emitting assembly 200 is positioned opposite at least a portion of the second heat conductive portion 412, and at least a portion of the heat dissipation fin assembly 420 is thermally connected to the second heat conductive portion 412.

[0076] The light emitting assembly 200 is used to generate and emit light to the light outlet 11 .

[0077] When using the technical solution of this embodiment, the heat generated by the cold pack assembly 300 is thermally conducted by the first thermal conductive part 411 through the thermal conductive structure, and then transmitted to the second thermal conductive part 412, and dissipated by the heat dissipation fin assembly 420 thermally connected to the second thermal conductive part 412. In this application, the second thermal conductive part 412 thermally connected to the heat dissipation fin assembly 420 is installed corresponding to the light emitting assembly 200, so that the distance between the heat dissipation fin assembly 420 and the cold pack assembly can be made closer, thereby shortening the heat conduction path.

[0078] In other words, the heat dissipation fin assembly 420 and the light-emitting assembly 200 are stacked (installed in a layered configuration) in the thickness direction of the casing assembly 100. Compared with the prior art in which the cold pack assembly, the light-emitting assembly and the heat dissipation fin assembly are arranged in a "linear" order, the skin treatment device in this embodiment can shorten the overall length of the heat conduction structure 410 and shorten the heat conduction path, bringing the distance between the heat dissipation fin assembly 420 and the light-emitting assembly 200 closer, thereby improving the heat dissipation efficiency and solving the problem in the prior art that the relatively long length of the heat conduction member of the skin treatment device affects the heat dissipation efficiency of the heat dissipation fin assembly.

[0079] Moreover, the heat-conducting structure 410 extends along the light-emitting direction of the light-emitting assembly 200 .

[0080] Furthermore, the heat conduction structure 410 has a capillary heat conduction channel and a heat conduction medium disposed in the capillary flow channel, the first heat conduction section 411 is an evaporation section, and the second heat conduction section 412 is a condensation section.

[0081] In this embodiment, depending on the wavelength setting of the light emitted from the light emitting assembly 200, it can be used as a hair removal device and / or as a skin rejuvenation device.

[0082] In one embodiment, the light emitting assembly 200 may be an IPL (Intense Pulsed Light) light emitting source assembly to generate strong pulsed light, also called pulsed strong light. The strong pulsed light is a broad spectrum light formed by focusing and filtering a light source with a very high intensity, and the wavelength of the IPL is often 400 nm to 200 nm, and different wavelengths have different effects. For example, when the wavelength of the IPL is 690 nm to 1200 nm, it mainly has a hair removal effect by utilizing the photothermolysis principle of the strong pulsed light. Since the melanocytes in the hair follicle can selectively absorb light of a specific wavelength band, and the IPL light can penetrate the epidermis and directly reach the hair follicle in the dermis, the light energy is absorbed by the melanocytes in the hair follicle in the dermis and converted into thermal energy, which increases the temperature of the hair follicle, and when the temperature of the hair follicle is high enough, irreversible destruction occurs in the hair follicle structure, and the destroyed hair follicle falls off naturally after a certain period of time, thereby slowing down hair growth in a short period of time and even stopping it from growing. When the wavelength of the IPL is 560nm-640nm, it mainly has the effect of skin rejuvenation. Or, the light-emitting assembly 200 is a laser light-emitting assembly, which generates a laser beam to realize hair removal by laser.

[0083] In this embodiment, the heat dissipation assemblies 400 are located on one side of the light emitting assembly 200. In this manner, all the heat dissipation assemblies 400 are located on one side of the light emitting assembly 200, so that the heat dissipation assemblies 400 and the light emitting assemblies 200 are stacked in the thickness direction of the casing assembly 100, simplifying the structure.

[0084] As shown in Fig. 1, the casing assembly 100 has a casing outlet 1201, and at least a part of the heat dissipation assembly 400 is located between the casing outlet 1201 and the light emitting assembly 200, so that at least a part of the heat dissipation assembly 400 is installed corresponding to the casing outlet 1201. In this manner, the heat dissipation assembly 400 is located above the light emitting assembly 200, ensuring that the airflow after heat exchange is smoothly discharged from the casing outlet 1201, and preventing the hot air from accumulating in the skin treatment device, causing the entire device to heat up, and further affecting the service life of the skin treatment device. In addition, the above installation makes the structural layout of the heat dissipation assembly 400 in the skin treatment device more reasonable and compact.

[0085] 1, the casing assembly 100 includes a housing 110. The light outlet 11 is located at a first end of the housing 110, and the first end of the housing 110 has a necking portion 111. In this manner, the front end of the skin treatment device has a necking shape due to the above-mentioned installation, and the obstruction of the operating position of the skin treatment device on the skin by the front end of the casing assembly 100 can be reduced, making it easier for the user to observe and change the mode or treatment position according to the treatment or operating situation.

[0086] In this embodiment, the height of at least a part of the heat dissipating fin assembly 420 is gradually reduced along the light emission direction of the light emitting assembly 200 so as to fit the necking portion 111. In this way, the above-mentioned installation can better fit the heat dissipating fin assembly 420 and the necking portion 111, and can avoid the motion interference between the two during attachment and detachment, which may affect the normal attachment and detachment of the skin treatment device.

[0087] 7, the heat dissipation fin assembly 420 has a first side 421 and a second side 422, the first side 421 is disposed toward the first end of the housing 110, the second side 422 is disposed away from the light emitting assembly 200, and a notch 423 is provided at the connection point between the first side 421 and the second side 422, and the notch 423 is disposed corresponding to the necking portion 111. In this way, due to the above-mentioned arrangement of the notch 423, the position corresponding to the notch 423 at the front end of the casing assembly 100 may be designed in a necking shape, and due to the above-mentioned arrangement, during the process of the user using the skin treatment device, the front end of the casing assembly 100 can reduce the obstruction of the user's observation of the operating position of the skin treatment device on the user's skin, making it easier for the user to observe.

[0088] 7, the heat dissipating fin assembly 420 further includes a transition surface 424, the first side surface 421 is connected to the second side surface 422 via the transition surface 424, the transition surface 424 and the first side surface 421 are disposed at an angle, and the transition surface 424 and the second side surface 422 are disposed at an angle, and a notch 423 is formed between the transition surface 424 and the housing 110. In this way, the transition surface 424 is disposed at an angle with both the first side surface 421 and the second side surface 422 and is located at the connection point between the two, which makes the processing of the notch 423 easier and simpler, and reduces the overall processing cost and processing difficulty of the heat dissipating fin assembly 420.

[0089] Optionally, the transition surface 424 is an inclined surface or a circular arc surface, or the transition surface 424 includes a first sub-transition surface 4241 and a second sub-transition surface 4242 that are arranged at an angle, the first sub-transition surface 4241 is connected to the first side surface 421, the second sub-transition surface 4242 is connected to the second side surface 422, the first sub-transition surface 4241 is a first plane or a first circular arc surface, and the second sub-transition surface 4242 is a second plane or a second circular arc surface. In this way, the above arrangement makes the shape selection of the transition surface 424 more diverse, meets different usage needs and working situations, and enhances the processing flexibility of the operator.

[0090] In this embodiment, the transition surface 424 includes a first sub-transition surface 4241 and a second sub-transition surface 4242 that are arranged at an angle, the first sub-transition surface 4241 is connected to the first side surface 421, the second sub-transition surface 4242 is connected to the second side surface 422, the first sub-transition surface 4241 is a first arc surface, and the second sub-transition surface 4242 is a second arc surface. In this way, the heat dissipation fin assembly 420 has a larger heat dissipation area due to the above arrangement compared to the inclined notch, thereby improving the heat dissipation ability of the heat dissipation fin assembly 420.

[0091] In this embodiment, the heat dissipating fin assembly 420 includes a plurality of heat dissipating fins 425 spaced apart along a first direction, with a first side edge of each heat dissipating fin 425 forming a first side surface 421 and a second side edge of each heat dissipating fin 425 forming a second side surface 422. Each heat dissipating fin 425 extends along a second direction, with the first direction and the second direction being angled, and the second direction being aligned with the light emission direction of the light emitting assembly 200. Optionally, the second direction is aligned with the front-rear direction of the casing assembly 100, and the first direction and the second direction are aligned perpendicular to each other. In this manner, the arrangement of the plurality of heat dissipating fins 425 within the casing assembly 100 is more reasonable and compact, the heat dissipation area of ​​the heat dissipating fin assembly 420 is significantly increased, and the heat dissipation efficiency of the heat dissipating fin assembly 420 is improved.

[0092] In this embodiment, the transition surface 424 includes a first sub-transition surface 4241 and a second sub-transition surface 4242 that are arranged at an angle, the first sub-transition surface 4241 is connected to the first side surface 421, and the second sub-transition surface 4242 is connected to the second side surface 422, and each heat dissipation fin 425 includes a heat dissipation fin body 4251 and a burring 4252. The heat dissipation fin body 4251 has a first side surface 421, a second side surface 422, and a second sub-transition surface 424. The burring 4252 is arranged on the heat dissipation fin body 4251 and arranged at an angle with the heat dissipation fin body 4251, and a first sub-transition surface 424 is formed on the surface of the burring 4252 that is away from the heat dissipation fin body 4251. A ventilation channel 4253 is formed between the heat dissipation fin bodies 4251 of two adjacent heat dissipation fins 425, and the burring 4252 of each heat dissipation fin 425 is used to contact its adjacent heat dissipation fin 425 and block at least a part of the ventilation channel 4253 to form an air outlet 427 on both sides of the burring 4252. Specifically, the burring 4252 plays the role of a stopper and is a stopper part, and the above-mentioned arrangement of the first sub-transition surface 4241 and the second sub-transition surface 4242 correspondingly forms a first notch part and a second notch part, thereby avoiding the direct formation of a stopper part on the notch 423, so that the wind entering the ventilation channel 4253 can flow at a preset speed by the stopper part, and the stopper part can avoid occupying a large area and affecting the arrangement of the air outlet 427.

[0093] Specifically, the burring 4252 is formed on the heat dissipating fin 425 to form the ventilation channel 4253. During manufacturing, the burring 4252 can be formed by leaving a margin in the first notch of the heat dissipating fin 425 and bending the margin to one side. That is, by forming the first notch and the second notch, the burring 4252 can be easily formed in the first notch. In addition, the burring 4252 is used to abut the adjacent heat dissipating fin 425 when subjected to external force, and prevents the heat dissipating fin 425 from being too thin and easily deforming, affecting the interval between the heat dissipating fins 425 and affecting the heat dissipation effect. In addition, the burring 4252 increases the contact area between the heat dissipating fin 425 and the air, and further improves the heat dissipation effect of the heat dissipating fin 425.

[0094] It should be noted that the structure of the heat dissipation fin assembly 420 is not limited to the above and can be adjusted according to the working conditions and usage needs.

[0095] In another embodiment not shown, a ventilation channel is formed between two adjacent heat dissipation fins, and the heat dissipation fin assembly further includes a stopper portion. The stopper portion is disposed on a third side edge of at least one heat dissipation fin to block at least a part of the ventilation channel. The surface of the stopper portion away from the light emitting assembly forms a first sub-transition surface to form air outlets on both sides of the stopper portion, and the other third side edge forms a second sub-transition surface. In this way, by the above-mentioned disposition of the first sub-transition surface and the second sub-transition surface, the first notch portion and the second notch portion are formed correspondingly, so that the stopper portion can be avoided from directly forming the stopper portion on the notch, thereby allowing the wind entering the ventilation channel to flow at a preset speed by the stopper portion, and avoiding the stopper portion occupying a large area to affect the installation of the air outlet.

[0096] In this embodiment, an air channel 4253 is formed between two adjacent heat dissipation fins 425, and the heat dissipation fin assembly 420 has an inlet and an outlet 427, the inlet communicates with the outlet 427 through the air channel 4253, the inlet is located on the side away from the first side 421 of the heat dissipation fin assembly 420, and the outlet 427 is located on at least one of the first side 421, the second side 422, and the notch 423. In this way, the airflow blown out from the outlet of the fan enters the heat dissipation fin assembly 420 through the inlet, then flows through the air channel 4253, carries away heat on the surface of the heat dissipation fin 425, and finally discharges through the outlet 427, smoothly flowing through the heat dissipation fin assembly 420 and avoiding heat accumulation. In addition, by displacing the intake position and the exhaust position of the heat dissipating fin assembly 420 from each other, the above-mentioned installation prevents the turbulence and impact of hot air inside the heat dissipating fin assembly 420 from affecting the normal flow of gas.

[0097] Optionally, the outlet 427 includes a first sub-outlet 4271 located on the first side 421 and a second sub-outlet 4272 located on the second side 422 and / or in the notch 423 .

[0098] Optionally, the ratio of the length of the notch 423 to the length of the heat dissipation fin 425 is greater than or equal to 0.32 and less than or equal to 0.55. As can be seen, the greater the ratio, the greater the length of the notch 423 can be, and the easier it is to provide a relatively long necking portion.

[0099] Optionally, the ratio of the width of the notch 423 to the width of the heat dissipation fin 425 is greater than or equal to 0.36 and less than or equal to 0.6. As can be seen, the larger the ratio, the larger the width of the notch 423 can be, and the easier it is to provide a relatively long necking portion.

[0100] As can be seen, by arranging the notch 423 as described above, the notch 423 has a sufficient clearance for the necking portion to escape, and can also ensure the heat dissipation of the heat dissipation fin assembly. Optionally, the heat dissipation fin assembly 420 and the light emitting assembly 200 are respectively located on both sides of the heat conducting structure 410. In this way, the installation difficulty and design difficulty can be easily reduced. As can be understood, in another embodiment, according to the heat dissipation demand, the end of the heat dissipation fin assembly 420 away from the light output can be folded and extended to the side where the light emitting assembly 200 is located, so as to increase the heat dissipation area of ​​the heat dissipation fin assembly.

[0101] In this way, the above-mentioned arrangement makes it possible to flexibly select the length and width of the notch 423, so as to meet different usage needs and working conditions, and to enhance the flexibility of the operator in processing. The above-mentioned arrangement also ensures that the hot air generated during the heat dissipation of the heat dissipation fin 425 can be dissipated through the first sub-air outlet 4271 and the second sub-air outlet 4272, so as to prevent the heat from accumulating in the heat dissipation fin assembly 420 and being unable to be dissipated, and further enhances the heat dissipation efficiency of the heat dissipation fin assembly 420.

[0102] In this embodiment, the ratio between the length of the notch 423 and the length of the heat dissipating fin 425 is 0.4, and the ratio between the width of the notch 423 and the width of the heat dissipating fin 425 is 0.5. In this way, the above arrangement makes it possible to select the size of the notch 423 more reasonably, and also reduces the processing cost and difficulty of the notch 423.

[0103] In addition, the selection of the ratio between the length of the notch 423 and the length of the heat dissipation fin 425 is not limited thereto, and can be adjusted according to the working conditions and usage needs. Optionally, the ratio between the length of the notch 423 and the length of the heat dissipation fin 425 is 0.35, or 0.42, or 0.45, or 0.50, or 0.52.

[0104] In addition, the selection of the ratio between the width of the notch 423 and the width of the heat dissipation fin 425 is not limited thereto, and can be adjusted according to the working conditions and the usage needs. Optionally, the ratio between the width of the notch 423 and the width of the heat dissipation fin 425 is 0.38, or 0.40, or 0.42, or 0.45, or 0.52, or 0.55, or 0.58.

[0105] Optionally, the light emitting assembly 200 includes a light emitter 210 and a filter 220, and along the light output direction of the light emitting assembly 200, the distance between the first side surface 421 and the filter 220 is 9 mm or less. In this manner, the light emitted from the light emitting assembly 200 is irradiated to the light transmitting body 310 after being filtered through the filter 220, and due to the above-mentioned installation, the first side surface 421 is installed close to the filter 220, and thus there can be a relatively long distance between the first side surface and the light output port 11, and therefore the necking portion 111 has a relatively large inclination.

[0106] The area behind the filter 220 is an area where the light emission temperature of the light emitter 210 is relatively high, so that the heat can be easily dissipated by the heat dissipation fin assembly 420 .

[0107] It should be noted that along the light emission direction of the light emitting assembly 200, the first side surface 421 may be located at the front end or the rear end of the filter 220.

[0108] As shown in FIGS. 1 to 3, the housing 110 includes a first side plate 112 and a second side plate 113. The second side plate 113 is disposed opposite the first side plate 112, and the first side plate 112 is located on the side of the heat dissipation fin assembly 420 that is away from the light emitting assembly 200. The surface of the first side plate 112 disposed opposite the second side surface 422 of the heat dissipation fin assembly 420 forms a first extension portion 1121, and at least a part of the first extension portion 1121 is gradually bent toward the second side plate 113 along the light emission direction of the light emitting assembly 200 to form at least a part of the necking portion 111. In this way, the first extension portion is gradually extended from the rear to the front so as to approach the second side plate 113 so that the front end of the casing assembly 100 is disposed in a necking shape, thereby preventing the front end from blocking the user's line of sight during the process of the user operating the skin treatment device.

[0109] 4 and 32, the casing assembly 100 further includes a bracket assembly 120. The bracket assembly 120 is installed in the receiving chamber, the bracket assembly 120 has a first mounting chamber 121 and a second mounting chamber 122, the light emitting assembly 200 is installed in the first mounting chamber 121, and the heat dissipation fin assembly 420 is installed in the second mounting chamber 122, and at least a part of the second mounting chamber 122 is projected onto the first mounting chamber 121 along the longitudinal direction of the housing 110 within the first mounting chamber 121. In this manner, the above installation allows the heat dissipation fin assembly 420 and the light emitting assembly 200 to be installed offset in the longitudinal direction of the housing 110, which further ensures that the overall length of the heat conduction structure 410 is shortened and the heat conduction path is shortened. In addition, the above-mentioned installation makes the structural layout of the light emitting assembly 200 and the heat dissipating fin assembly 420 in the housing 110 more reasonable and compact, and improves the utilization rate of the internal space.

[0110] As shown in FIG. 9, the bracket assembly 120 has a first ventilation surface 123 disposed toward the first extension portion 1121, and at least a portion of the first ventilation surface 123 is adjacent to the second side plate 113 so as to fit the first extension portion 1121 along the light emission direction of the light emitting assembly 200. The first ventilation surface 123 has a first ventilation port 1231 communicating with the second mounting chamber 122. In this manner, the airflow that has completed heat exchange with the heat dissipation fin assembly 420 is blown out through the first ventilation surface 123, and the first ventilation surface 123 fits the necking portion 111, thereby preventing structural interference between the bracket assembly 120 and the necking portion 111. In addition, the first ventilation port 1231 communicates with the second mounting chamber 122, thereby ensuring that gas can flow inside the heat dissipation fin assembly 420 to perform heat exchange.

[0111] 9 to 14, the bracket assembly 120 includes a heat dissipation fin bracket 124 and a light-emitting side bracket 125 located on both sides of the heat-conducting structure 410 and connected to each other, the light-emitting side bracket 125 has a first mounting chamber 121, the heat dissipation fin bracket 124 has a second mounting chamber 122, a first ventilation surface 123, and a mounting opening 1241, and the heat dissipation fin assembly 420 is mounted in the second mounting chamber 122 through the mounting opening 1241. In this way, by mounting the heat dissipation fin assembly 420 in the casing assembly 100 through the heat dissipation fin bracket 124 and mounting the light-emitting assembly 200 in the casing assembly 100 through the light-emitting side bracket 125, the heat dissipation fin assembly 420 and the light-emitting assembly 200 can be attached and detached more easily and simply, the difficulty of attachment and detachment is reduced, and the positions of both are fixed in the casing assembly 100, preventing the movement or movement of both from affecting the stability of the internal structure of the skin treatment device. Also, by attaching and detaching the heat dissipation fin assembly 420 through the attachment opening 1241, the worker can attach and detach the heat dissipation fin assembly 420 more easily and simply, and the difficulty of attaching and detaching is reduced. Furthermore, by using the heat dissipation fin bracket 124 and the light-emitting side bracket 125, heat dissipation flow paths that dissipate heat from the heat dissipation fin assembly 420 and the light-emitting assembly 200 can be formed, respectively, and the heat dissipation effect is improved.

[0112] As shown in FIGS. 2 to 4, the skin treatment device further includes a fan 500. The fan 500 is installed in the accommodation chamber and located on the side away from the light outlet 11 of the heat dissipation fin assembly 420. The heat dissipation fin bracket 124 has a second vent 1242, and the outlet of the fan 500 communicates with the second mounting chamber 122 through the second vent 1242. In this way, it is ensured that the cool air blown out from the outlet of the fan 500 can enter the second mounting chamber 122 through the second vent 1242 and exchange heat with the heat dissipation fin assembly 420, thereby blowing on the heat dissipation fin assembly 420 to cool it.

[0113] As shown in Figures 9 to 12, the heat dissipation fin bracket 124 includes a first bracket, which includes a first support part 131, a first side support part 132, a second support part 133, and a second side support part 134, which are connected in order, the first support part 131 and the second support part 133 are arranged opposite each other and connected to the second side support part 134, the first side support part 132 is arranged opposite the second side support part 134, and the second support part 133 is arranged farther from the light outlet 11 than the first support part 131.

[0114] The first support portion 131, the first side support portion 132, the second support portion 133, and the second side support portion 134 together form the second mounting chamber 122 and the first ventilation hole 1231, the side walls of the first support portion 131, the first side support portion 132, the second support portion 133, and the second side support portion 134 facing away from the light-emitting assembly 200 form the first ventilation surface 123, and the second support portion 133, the first side support portion 132, and the second side support portion 134 together form the second ventilation hole 1242.

[0115] In this way, with the above-mentioned installation, a relatively large space can be formed in the center of the heat dissipation fin bracket 124 to accommodate the heat dissipation fin assembly 420, and the multiple support parts ensure structural strength. In addition, the structure of the heat dissipation fin bracket 124 can be relatively simple, and it is easy to form the first ventilation hole 1231, the first ventilation surface 123 and the second ventilation hole 1242.

[0116] A gap is formed between the first support portion 131 and the inner wall of the housing 110, so that the wind in the second mounting chamber 122 can flow from the gap to the casing outlet portion 1201 and then be blown out to the outside of the housing 110 through the casing outlet portion 1201.

[0117] In this embodiment, the first support part 131 includes a first support plate 1311 installed in the horizontal direction, the second support part 133 includes a second support plate 1331 installed in the horizontal direction, the first side support part 132 includes a third support plate 1321 installed in the vertical direction, and the second side support part 134 includes a fourth support plate 1341 installed in the vertical direction, and both ends of the first support plate 1311 are respectively connected to the inner plate surface of the third support plate 1321 and the inner plate surface of the fourth support plate 1341, and both ends of the second support plate 1331 are respectively connected to the third support plate 1321 and the fourth support plate 1341. The second support plate 1331 is connected to the inner plate surface of the first support plate 1321 and the inner plate surface of the fourth support plate 1341, and the side edge of the second support plate 1331 facing the fan 500, the side edge of the third support plate 1321 facing the fan 500, and the side edge of the fourth support plate 1341 facing the fan 500 together form a second ventilation hole 1242, and the side edge of the first support plate 1311 facing the third support plate 1321, the third support plate 1321, the fourth support plate 1341, and the side edge of the second support plate 1331 facing the first support part 131 together form a first ventilation hole 1231. In this way, with the above-mentioned installation, the formation of the first ventilation hole 1231 and the second ventilation hole 1242 is easier and simpler, and the plate-shaped design reduces the processing cost and processing difficulty of the first bracket, improves the structural strength and ventilation performance of the first bracket, and ensures that the cold air blown out from the outlet of the fan 500 can enter the first bracket and cool the heat dissipation fin assembly 420.

[0118] Optionally, the casing assembly 100 has a casing outlet 1201, and the side of the first support plate 1311 facing away from the fan 500, the side of the third support plate 1321 facing away from the fan 500, and the side of the fourth support plate 1341 facing away from the fan 500 are surrounded to form a third ventilation hole 135, which is connected to both the second mounting chamber 122 and the casing outlet 1201.

[0119] Optionally, the first support plate 1311 is installed opposite the first sub-transition surface 4241 of the heat dissipation fin assembly 420 .

[0120] Optionally, at least a portion of the side edge of the third support plate 1321 that faces away from the light emitting assembly 200 and at least a portion of the side edge of the fourth support plate 1341 that faces away from the light emitting assembly 200 gradually bend toward the second side plate 113 so that at least a portion of the first ventilation surface 123 gradually bends toward the second side plate 113 along the light emission direction of the light emitting assembly 200.

[0121] Optionally, the notch is located in the first vent 1231 .

[0122] Thus, the above-mentioned arrangement of the third ventilation hole 135 allows air to flow smoothly inside the housing 110, and prevents hot air from accumulating and affecting the heat dissipation performance of the skin treatment device. Also, the above-mentioned arrangement allows the outer shape of the first bracket to be well matched to the outer shape of the housing 110, and prevents structural interference between the first bracket and the housing 110 from affecting attachment and detachment of the skin treatment device.

[0123] Optionally, a first windbreak protrusion 136 is provided on the inner wall of the third support plate 1321, and the first windbreak protrusion 136 is installed adjacent to the side edge of the second support plate 1331 that is away from the light-emitting assembly 200 and extends along the extension direction of this side edge.

[0124] As can be seen, by installing the first windproof protrusion 136, the wind that enters the gap between the heat dissipation fin assembly 420 and the third support plate 1321 will not flow out of this gap through the first ventilation hole as quickly, thereby lengthening the interaction time with the heat dissipation fin assembly.

[0125] Optionally, a second windbreak protrusion 137 is provided on the inner wall of the fourth support plate 1341, and the second windbreak protrusion 137 is installed adjacent to the side edge of the third support plate 1321 that is away from the light-emitting assembly 200 and extends along the extension direction of this side edge.

[0126] As can be seen, by installing the second windbreak protrusion 137, the wind that enters the gap between the heat dissipation fin assembly 420 and the fourth support plate 1341 does not flow out of this gap through the first ventilation hole as quickly, thereby lengthening the interaction time with the heat dissipation fin assembly and improving the heat dissipation effect.

[0127] Optionally, a third windbreak protrusion 138 is provided on the inner wall of the fourth support plate 1341, and the third windbreak protrusion 138 is located closer to the first support portion 131 than the second support portion 133 and extends along a direction toward or away from the light-emitting assembly 200.

[0128] As can be seen, by installing the third windproof protrusion 138, the wind that enters the gap between the heat dissipation fin assembly 420 and the fourth support plate 1341 will not flow out of this gap through the third ventilation hole as quickly, thereby lengthening the interaction time with the heat dissipation fin assembly.

[0129] In this manner, the above-mentioned installation of the windproof protrusion not only serves to support and regulate the heat dissipation fin assembly 420, preventing it from rattling or moving, but also forms a ventilation gap between the heat dissipation fin assembly 420 and the first bracket, ensuring that the airflow from the heat dissipation fin assembly 420 that has completed heat dissipation can be discharged to the outside of the housing 110 through the gap.

[0130] As shown in FIGS. 9 to 11, the heat dissipation fin bracket 124 further includes a first outer support part 141 that is installed on the outer wall of the first side support part 132 and connected to the light-emitting side bracket 125.

[0131] As shown in FIGS. 9 to 11, the heat dissipation fin bracket 124 further includes a second outer support part 1243 that is installed on the outer wall of the second side support part 134 and connected to the light-emitting side bracket 125.

[0132] In this way, heat dissipation fin bracket 124 is connected to light-emitting side bracket 125 via first outer support part 141 and second outer support part 1243, thereby fixing the mounting position of bracket assembly 120 within housing 110 and preventing any influence on the stability of the overall structure of the skin treatment device due to movement or motion. In addition, with the above installation, the mounting positions of heat dissipation fin bracket 124 and light-emitting side bracket 125 avoid the mounting position of heat dissipation fin assembly 420, thereby preventing any influence on normal heat dissipation of heat dissipation fin assembly 420 due to the connection between the two.

[0133] As shown in Figures 12 and 14, the casing assembly 100 has a casing outlet portion 1201, and the first outer support portion 141 and the light-emitting side bracket 125 surround it to form a first ventilation passage 151, which is connected to both the outlet of the fan 500 and the first mounting chamber 121, and at least a portion of the first ventilation passage 151 gradually bends toward the side away from the first extension portion 1121 along the light emission direction of the light-emitting assembly 200.

[0134] And / or, the second outer support portion 1243 and the light-emitting side bracket 125 surround each other to form a second ventilation passage 152, which is connected to both the casing blowing portion 1201 and the first mounting chamber 121.

[0135] In this way, a first ventilation passage 151 is formed by the structure of the first outer support part 141, which guides the air flowing into the first mounting chamber 121, and / or a second ventilation passage 152 is formed by the structure of the second outer support part 1243, which guides the air blown out of the first mounting chamber 121.

[0136] In one embodiment, the air blown out from the fan flows into the first mounting chamber 121 through the first ventilation passage 151 and flows out from the first mounting chamber 121 through the second ventilation passage 152, thereby realizing heat dissipation for the light-emitting assembly.

[0137] As shown in FIGS. 9 to 11, the first outer support part 141 includes a first air path plate 1411 and a second air path plate 1412. The first air path plate 1411 is installed on an outer wall of the third support plate 1321. The second air path plate 1412 is connected to a side edge of the first air path plate 1411 that is away from the first support plate 1311. The second air path plate 1412 is installed opposite the third support plate 1321. 1411, the third support plate 1321, and the second air path plate 1412 surround and form a part of the first ventilation flow path 151, and at least a part of the first air path plate 1411 gradually bends toward the side away from the first extension portion 1121 along the light emission direction of the light-emitting assembly 200 so that at least a part of the first ventilation flow path 151 gradually bends toward the side away from the first extension portion 1121.

[0138] 9 to 11, the second outer support part 1243 includes a first flow path plate 1243a and a second flow path plate 1243b, the first flow path plate 1243a is installed on the outer wall of the fourth support plate 1341, the second flow path plate 1243b is connected to a side edge of the first flow path plate 1243a away from the second support plate 1331, the second flow path plate 1243b is installed facing the fourth support plate 1341, the second ventilation flow path 152 includes a ventilation duct opening 1521 and a pressurization sub-chamber 1522, the ventilation duct opening 1521 is located in the first flow path plate 1243a, The first flow path plate 1243a, the second flow path plate 1243b and the fourth support plate 1341 together form a pressurized sub-chamber 1522, which is connected to the casing outlet portion 1201 and which is connected to the first mounting chamber 121 via the ventilation duct opening 1521. The second outer support portion 1243 further includes a light-shielding flow guide portion 1243c, which is installed on the fourth support plate 1341 and the second flow path plate 1243b, and which at least partially shields the ventilation duct opening 1521.

[0139] In this manner, the first ventilation passage 151 is an arc-shaped passage to ensure that the cool air blown out from the outlet of the fan 500 can flow through the arc-shaped passage into the light emitting assembly 200 to cool it. As described above, the second ventilation passage 152 includes the ventilation duct opening 1521 and the boost sub-chamber 1522, thereby boosting the air flowing out from the first mounting chamber 121 and preventing heat from being trapped or accumulated.

[0140] In addition, the gas flowing out from downstream of the light-emitting assembly 200 is branched in the light-shielding flow-guiding section 1243c to form at least two outlet air currents and discharged from the casing outlet section 1201, thereby preventing the light-emitting assembly 200 from becoming too hot due to heat accumulation downstream of the light-emitting assembly 200.

[0141] Specifically, a portion of the airflow blown out from the air outlet of the fan 500 directly enters the second mounting chamber 122 to cool the heat dissipation fin assembly 420, and the other portion enters the first air passage 151 and passes through the light emitting assembly 200 before being discharged from the second air passage 152. The boost sub-chamber 1522 located in the second air passage 152 can increase the blowing space of the second air passage 152, and the hot air that has cooled the light emitting assembly 200 can be quickly discharged from the second air passage 152, thereby avoiding heat accumulation.

[0142] Selectively, first attachment portion 142 for engaging with light-emitting side bracket 125 is provided on first air path plate 1411 and / or second air path plate 1412, and / or second attachment portion 143 for engaging with light-emitting side bracket 125 is provided on first flow path plate 1243a and / or second flow path plate 1243b. In this manner, with the above-mentioned installation, first bracket 125 and light-emitting side bracket 125 are engaged and fitted together, realizing a detachable connection between the two, making attachment and detachment between the two easier and simpler, and reducing the difficulty of attachment and detachment.

[0143] 2 to 6, the cold pack assembly 300 includes an optically transparent body 310, and the light-emitting bracket 125 further has a third mounting chamber 1251 located between the first mounting chamber 121 and the light exit port 11, and the optically transparent body 310 is mounted in the third mounting chamber 1251. In this manner, the optically transparent body 310 is used to come into contact with the skin to be treated and to cool the skin to be treated or the skin near the skin to be treated.

[0144] 13 and 14, the light-emitting side bracket 125 includes a second bracket 1252 and a third bracket 1253 located between the second bracket 1252 and the light output port 11. The second bracket 1252 has a first mounting chamber 121 and a bracket light output port 1252a, and the first mounting chamber 121 communicates with the light output port 11 through the bracket light output port 1252a. The third bracket 1253 is connected to the second bracket 1252 and has a third mounting chamber 1251. In this manner, the second bracket 1252 is used to support and fix the light-emitting assembly 200 so as to prevent the movement or motion of the light-emitting assembly 200 in the casing assembly 100 from affecting the stability of the internal structure of the skin treatment device. To prevent the optically transparent body 310 from moving or shifting within the casing assembly 100 and affecting the stability of the internal structure of the skin treatment device, a third bracket 1253 is used to support and fix the optically transparent body 310.

[0145] 13 and 14, the second bracket 1252 includes a first mounting plate 161, a first side portion 162 installed on one side of the first mounting plate 161, and a second side portion 163 installed on the other side of the first mounting plate 161, the first mounting plate 161 is installed toward the light output port 11 and is surrounded by the first side portion 162 and the second side portion 163 to form a first mounting chamber 121, and a bracket light output port 1252a is formed between the first side portion 162 and the second side portion 163. In this way, by the above installation, the second bracket 1252 has a U-shaped structure, and further regulates the light output direction of the light emitting assembly 200 to ensure that the light generated from the light emitting assembly 200 enters the light output port 11 after passing through the bracket light output port 1252a.

[0146] As shown in FIGS. 12 to 14, the light emitting assembly 200 includes a light emitter 210 and a light reflecting cup 230 disposed around the light emitter 210. As shown in FIG.

[0147] As shown in FIGS. 12 to 14, a mounting insertion hole is provided in the first mounting plate 161, and the light reflecting cup 230 has an insertion pin 231 that is inserted into the mounting insertion hole.

[0148] As shown in Figures 12 to 14, an abutment protrusion is provided on the inner surface of the first mounting plate 161, and the light reflecting cup 230 abuts against the abutment protrusion, thereby forming an air ventilation gap between the light reflecting cup 230 and the inner surface of the first mounting plate 161.

[0149] In this manner, the light reflecting cup 230 and the first mounting plate 161 are detachably connected by the above-mentioned installation, and the attachment and detachment of the light reflecting cup 230 and the first mounting plate 161 is facilitated and simplified, reducing the difficulty of attachment and detachment. In addition, the cool air that enters the first ventilation passage 151 can pass through the ventilation gap, and smoothly flow inside the light emitting assembly 200 and perform heat exchange.

[0150] As shown in Figures 33 to 38, the light-emitting assembly 200 further includes a filter 220 disposed between the light-emitting body 210 and the light-transmitting body 310, and a sealing structure 240 that seals the gap between the filter 220 and the light-transmitting body 310.

[0151] In one embodiment, the sealing structure 240 is located outside the spot where the light emitter 210 irradiates the filter 220. In this way, the sealing structure 240 is located outside the covering space of the light-emitting port of the light emitter 210, so that the light emitted from the light-emitting port is not directly irradiated to the sealing structure 240, thereby avoiding the problem in the prior art that the sealing structure is easily aged / carbonized under long-term irradiation of light, and further extending the service life of the sealing structure 240 and the skin treatment device, and preventing powdery foreign matter from affecting the light emission.

[0152] 15 to 17, both sides of the first mounting chamber 121 are open, and the third bracket 1253 includes a first connection support part 171 and a second connection support part 172 extending toward the second bracket 1252, and the first connection support part 171 and the second connection support part 172 are both connected to the second bracket 1252 and cover the two open parts. In this way, the first connection support part 171 and the second connection support part 172 prevent the influence on the user's usage experience caused by the light leakage phenomenon of the light emitting assembly 200, and ensure that all the light rays generated by the light emitter 210 are emitted through the light emission port 11.

[0153] As shown in Figures 13 and 14, the second bracket 1252 further includes a first flow guide portion 181 installed at one end of the first mounting plate 161, the first side portion 162, and the second side portion 163, and the first flow guide portion 181 is engaged with the heat dissipation fin bracket 124 to form a first ventilation flow path 151 communicating with the first mounting chamber 121.

[0154] 13 and 14, the second bracket 1252 further includes a second guiding part 182 installed at the other end of the first mounting plate 161, the first side part 162, and the second side part 163, and the second guiding part 182 is fitted to the heat dissipation fin bracket 124 to form a second ventilation passage 152 communicating with the first mounting chamber 121. In this manner, the first guiding part 181 is abutted against the first outer support part 141 to form the first ventilation passage 151, and / or the second guiding part 182 is abutted against the second outer support part 1243 to form the second ventilation passage 152, so that the cold air blown out from the outlet of the fan 500 enters the ventilation passage to cool the light emitting assembly 200, and the effect on the service life of the light emitting assembly 200 caused by an excessively high surface temperature of the light emitting assembly 200 is avoided.

[0155] 13 and 14, the first flow guide portion 181 includes a first side flow guide plate 1811, a second side flow guide plate 1812, and a third side flow guide plate 1813, the second side flow guide plate 1812 is installed opposite to the first side flow guide plate 1811, and the third side flow guide plate 1813 is connected to the first side flow guide plate 1811, the second side flow guide plate 1812, and the second side portion 163, and the first side flow guide plate 1811, the second side flow guide plate 1812, and the third side flow guide plate 1813 surround and form at least a part of the first ventilation flow path 151. In this way, the above-mentioned installation makes the structure of the first flow guide portion 181 simpler and easier to process, thereby realizing a reduction in the overall processing cost and difficulty of the skin treatment device.

[0198] Optionally, the third mounting plate 194 located in the fourth mounting chamber 1911 has an air hole 1941, and / or each third engagement protrusion 193 extends toward the light outlet 11 and extends to the side of the first connecting plate 1962 toward the light outlet 11. In this way, the above-mentioned installation of the air hole 1941 can cool the phototherapy lamp 900 and prevent the effect on the service life of the phototherapy lamp 900 caused by the excessively high surface temperature of the phototherapy lamp 900. In addition, the air hole 1941 plays a role of hollowing out, and can realize a lightweight design of the fourth bracket 191.

[0200] As shown in Fig. 18 and Fig. 19, the second surrounding plate 197 includes a third side plate portion 1971, a second connecting plate 1972, and a fourth side plate portion 1973, which are connected in order. The third side plate portion 1971 and the fourth side plate portion 1973 are installed opposite to each other and are both connected to the damper 195. A fourth engagement protrusion that is engaged and fitted to the second bracket 1252 is installed on the side of the first connecting plate 1962 that is away from the light outlet 11. In this way, the above installation makes the structure of the second surrounding plate 197 simpler and easier to process, thereby reducing the processing cost and difficulty of the second surrounding plate 197. In addition, the above installation makes it easier and simpler to attach and detach the fourth bracket 191 and the second bracket 1252, reducing the difficulty of attaching and detaching, and no structural interference occurs between the engagement positions of the two and the filter 220, making it easier for an operator to attach and detach them.

[0201] 18 and 19, a third support plate 1974 is provided on the outer surface of the third side plate portion 1971, the third support plate 1974 is used to support the third bracket 1253, and has a second engagement recess that is engaged with the third bracket 1253, and / or a fourth support plate 1975 is provided on the outer surface of the fourth side plate portion 1973, the fourth support plate 1975 is used to support the third bracket 1253, and has a third engagement recess that is engaged with the third bracket 1253.

[0202] Optionally, the heat conducting structure 410 is a vapor chamber or a heat pipe, and the heat dissipating fin assembly 420 and the light emitting assembly 200 are respectively located on opposite sides of the heat conducting structure 410. In this way, the above-mentioned arrangement allows the structure selection of the heat conducting structure 410 to be more flexible, meets different usage needs and working conditions, and enhances the processing flexibility of the operator. In addition, the above-mentioned arrangement allows the heat dissipating fin assembly 420 and the light emitting assembly 200 to be stacked in the thickness direction of the housing 110, shortening the overall length of the heat conducting structure 410 and improving the heat dissipation performance of the heat dissipation assembly 400.

[0203] In this embodiment, the heat conducting structure 410 is a vapor chamber, and the vapor chamber extends along the front-rear direction of the housing 110.

[0204] Optionally, the heat-conducting structure 410 further includes a third heat-conducting part further provided with a heat-dissipating fin assembly 420, which is connected to an end of the second heat-conducting part 412 away from the first heat-conducting part 411 and protrudes from the light-emitting assembly 200 along a direction opposite to the light-emitting direction of the light-emitting assembly 200. In one embodiment, the third heat-conducting part is a condensation part.

[0205] In this way, the above installation ensures that the orthogonal projection of the light emitting assembly 200 onto the heat conduction structure 410 is within the heat conduction structure 410, and the heat dissipation fin assembly 420 has a relatively large heat dissipation area, so that the heat dissipation fin assembly 420 can dissipate heat and cool the cold pack assembly 300 sufficiently and / or quickly.

[0206] In this embodiment, the cold pack assembly 300 includes a light-transmitting body 310 and a cooling sheet 800, the light-transmitting body 310 is provided in the casing assembly 100, is located on the side facing the light outlet 11 of the light-emitting assembly 200 and is installed corresponding to the light outlet 11, and is used to emit light generated from the light-emitting assembly 200 out of the light outlet 11, and the cooling sheet 800 has a cooling surface thermally connected to the light-transmitting body 310 and a heat-dissipating surface thermally connected to the first heat-conducting part 411. In this way, the first heat-conducting part 411 cools the light-transmitting body 310 through the cooling sheet 800, thereby preventing burns to the user caused by an excessively high surface temperature of the light-transmitting body 310.

[0207] Optionally, the cooling sheet 800 is one sheet or two sheets respectively connected to both sides of the light-transmitting body 310. The cooling sheet 800 can be a semiconductor cooling sheet, which includes a cooling surface and a heat dissipation surface facing each other, and the cooling surface contacts the side surface of the light-transmitting member.

[0208] Optionally, the casing assembly 100 has a longitudinal direction, which is arranged at an angle with the light emission direction of the light emitting assembly 200, and the angle is greater than or equal to 3 degrees and less than or equal to 55 degrees, for example, 6, 8, 10, 12, 14, 16, 18, 20, 22, 24, 26, 28, 30, 32, 34, 36, 38, 40, 42, 44, 46, 48, 50, 52, 54 or 55 degrees.

[0209] Preferably, this angle is 6 degrees or more and 36 degrees or less. In this way, in the process of using the skin treatment device, the above installation allows the housing 110 to be inclined toward the skin to be depilated / rejuvenated, improving the user's experience. For example, when depilating the face, when the contact surface is in contact with the face (e.g., when removing the beard), the housing 110 can be inclined downward to avoid the user's hand from rising too high and causing fatigue. For example, when depilating the lower leg, when the contact surface is in contact with the surface skin of the lower leg, the housing 110 is inclined toward the surface skin of the lower leg without pressing the surface skin of the lower leg vertically, to avoid the user's arm from being easily strained and becoming tired.

[0210] 12, in the embodiment 2 of the bracket assembly 120 of the present application, the bracket assembly 120 is similar to the embodiment 1 except that the third vent hole is not formed, but the heat dissipation chamber 105 is formed, the heat dissipation chamber 105 is located in the bracket assembly 120, and the heat dissipation chamber 105 communicates with at least one air port portion 12. In this way, the heat dissipation chamber 105 is formed in the chamber in the bracket assembly 120, and the wind in the heat dissipation chamber 105 is blown out through the air port portion 12 after heat exchange with the heat conducting structure 410. This form can also achieve the effect of accelerating heat dissipation.

[0211] Specifically, the first support part 131 includes a first support plate 1311 and a sub-support plate 1312 that are installed in a horizontal direction, one side of the sub-support plate 1312 is connected to the side of the first support plate 1311 that is away from the heat dissipation fin assembly 420, and the other side of the sub-support plate 1312 abuts against the heat conduction structure 410, and the area surrounded by the sub-support plate 1312 and the first support plate 1311 forms a heat dissipation chamber 105, which communicates with the first ventilation channel 151. In this way, the sub-support plate 1312 and the first support plate 1311 form the heat dissipation chamber 105, and the wind that enters the heat dissipation chamber 105 from the mounting chamber 101 enters the first ventilation channel 151 and is blown out through the air port part 12.

[0212] In the second embodiment, the first support part 131 further includes a guide plate 1313, one end of which is connected to at least one of the first support plate 1311 and the sub-support plate 1312, and the other end of which is connected to the first outer support part 141, and there is a guide port between the guide plate 1313 and the first outer support part 141, and the heat dissipation chamber 105 communicates with the first ventilation passage 151 through the guide port. The above-mentioned installation can guide the wind in the heat dissipation chamber 105, so that the wind in the heat dissipation chamber 105 is blown out through the first ventilation passage 151 after heat exchange, and realizes heat dissipation by carrying away heat.

[0213] In order to separate the heat dissipation chamber 105 from the second ventilation passage 152, the lateral ends of the first support plate 1311 and the sub support plate 1312 both extend to the second side support part 134, that is, in this embodiment, the wind in the heat dissipation chamber 105 can be blown out by passing through the first ventilation passage 151. Of course, in other embodiments, the heat dissipation chamber 105 may be connected to the second ventilation passage 152, and the wind may be blown out through the second ventilation passage 152.

[0214] As shown in Figures 20 to 31, the fan bracket 700 includes a support base portion 710, the main control board 600 is attached to the fan bracket 700 and / or the housing 110 and is located on one side of the support base portion 710, and the fan 500 is located on the side of the support base portion 710 away from the main control board 600. In this embodiment, the fan 500 and the main control board 600 are respectively installed on both sides of the support base portion 710 of the fan bracket 700, thus avoiding the fan 500 from occupying the space of the main control board 600, and since the main control board 600 has a relatively large area for installing devices, it is easier to arrange devices as needed, and since the fan 500 does not block the surface of the main control board 600 and the devices on the main control board 600, this area can be better ventilated and dissipate heat, and since the main control board 600 and the fan 500 are respectively attached to both sides of the support base portion 710, it is more advantageous for the support and installation of the main control board 600 and the fan 500 by the support base portion 710, which makes it easier to simplify the structure and facilitates assembly.

[0215] The first side plate 112 is located on the side of the main control board 600 that is away from the support base part 710, and the second side plate 113 is located on the side of the support base part 710 that is away from the first side plate 112, and the support base part 710 is installed apart from both the first side plate 112 and the second side plate 113. The chamber surrounded by the first side plate 112 and the second side plate 113 is used to mount components such as the main control board 600, the fan bracket 700, and the fan 500, and the first side plate 112 and the second side plate 113 can play a role in protecting these components. The support base part 710 is installed apart from both the first side plate 112 and the second side plate 113 to avoid interference during assembly.

[0216] 25, device 920 is attached to an area spaced apart from the first end of main control board 600. Since the space in the area spaced apart from the first end of main control board 600 is relatively large, device 920 can be easily arranged without interfering with other structures, and is advantageous for heat dissipation.

[0217] The support base 710 has a hollow chamber 711 located between the main control board 600 and the fan 500. The hollow chamber 711 can form a relatively large space between the main control board 600 and the fan 500, making it easy to arrange the device 920 in this area, and is favorable for gas flow and accelerating heat dissipation. In addition, the hollow chamber 711 can reduce the amount of material used and the weight of the device, provided that strength is ensured. In this embodiment, the device 920 is attached to the area of ​​the main control board 600 facing the hollow chamber 711.

[0218] 20 and 21, both ends of the fan 500 are connected to the first end and the second end, respectively, and the fan 500 is installed at an incline with respect to the main control board 600. In this way, the fan 500 is not only fixed by the first end and the second end of the support base part 710, but also at an incline with respect to the main control board 600, thereby preventing the fan 500 from excessively occupying space on the main control board 600, i.e., realizing the relief of the central area of ​​the main control board 600, which is favorable for the arrangement of the device 920 on the main control board 600 and the heat dissipation of the main control board 600 and the device 920.

[0219] Specifically, as shown in Figures 20 to 31, the support base portion 710 includes a first base portion 712 provided at a first end, a second base portion 713 provided at a second end, a first side base portion 714, and a second side base portion 715, the first side base portion 714 is installed opposite the second side base portion 715, one end of the first side base portion 714 and one end of the second side base portion 715 are each connected to the first base portion 712, and the other end of the first side base portion 714 and the other end of the second side base portion 715 are each connected to the second base portion 713, whereby the first base portion 712 and the main control board 600 are installed at a distance from each other.

In addition, the first base portion 712 and the second base portion 713 are used to support the fan 500.

[0221] The first base portion 712 includes a first base plate 7121 supporting the fan 500, the ends of which are connected to a first side base portion 714 and a second side base portion 715, respectively.

[0222] 25 and 29, the first base plate 7121 has an escape groove 7122, the opening of which is disposed toward the second base portion 713, and the escape groove 7122 allows the device 920 attached to the main control board 600 to escape. By providing the escape groove 7122, interference between the first base plate 7121 and the device 920 attached to the main control board 600 can be avoided. In this way, the device 920 having a relatively large height can be attached to the position of the escape groove 7122.

[0223] 29, the first base portion 712 further includes a first restriction flange 7123 located at an end close to the first side base portion 714 of the first base plate 7121, protruding from the side of the first base plate 7121 facing the fan 500, and fastened to and fitted on the outer wall of the fan 500, and / or the first base portion 712 further includes a second restriction flange 7124 located at an end close to the second side base portion 715 of the first base plate 7121, protruding from the side of the first base plate 7121 facing the fan 500, and fastened to and fitted on the outer wall of the fan 500. By installing the first restriction flange 7123 and the second restriction flange 7124, the fan 500 can be restricted in the longitudinal direction of the first base plate 7121, the accurate mounting position of the fan 500 can be ensured, and a position offset of the fan 500 can be avoided.

[0224] The second base portion 713 includes a second base plate 7131 and a supporting strip 7132, both ends of the second base plate 7131 are respectively connected to the first side base portion 714 and the second side base portion 715, the supporting strip 7132 is protruding from the side of the second base plate 7131 facing the fan 500, the supporting strip 7132 supports the fan 500, and the second base plate 7131 is spaced apart from the fan 500. The second base plate 7131 and the supporting strip 7132 realize support for the fan 500, and the supporting strip 7132 is a reinforcing rib that can enhance the structural strength of the second base plate 7131.

[0225] In this embodiment, the first side base portion 714 includes a first side body 7141 having both ends connected to the first base portion 712 and the second base portion 713, and the distance from the face of the first side body 7141 facing away from the main control board 600 to the main control board 600 gradually increases in the direction from the second end to the first end. The change in size of the first side body 7141 realizes the distance between the first base portion 712 and the main control board 600 and the inclined installation of the fan 500.

[0226] 26 and 30, the first side body 7141 has a first restricting step 7142 on the side facing the main control board 600, and the first restricting step 7142 is fitted in a restrictive manner to the surface of the main control board 600 facing the fan 500 and to the side surface of the main control board 600. The first restricting step 7142 realizes the mutual restriction between the first side body 7141 and the main control board 600 and ensures the accuracy of the assembly position.

[0227] Furthermore, the first side base portion 714 further includes a first locking portion 7143 that is located on the side of the first side body 7141 that is away from the fan 500 and that is engaged with the side of the main control board 600 that is away from the fan 500.

In this way, the change in size of the second side body 7151 realizes the distance between the first base portion 712 and the main control board 600 and the inclined installation of the fan 500.

[0229] Specifically, the second side body 7151 includes an inclined body 7151a and a protrusion 7151b, one end of the inclined body 7151a is connected to the second base portion 713, the surface of the inclined body 7151a facing away from the main control board 600 is a slope, the protrusion 7151b is installed at the other end of the inclined body 7151a and protrudes from the slope of the inclined body 7151a, the protrusion 7151b is connected to one end of the first base portion 712, and the inclined body 7151a is separated from the fan 500.

[0244] Specifically, photoepilation is based on the theory of selective photothermal action, where light of a specific wavelength penetrates the epidermis, does not damage the hair follicles in the epidermis, and the melanin in the hair shaft selectively absorbs the light energy, causing the hair follicles to heat up, coagulate and necrotize, effectively slowing down growth, thereby playing the role of hair removal. However, when the user's skin absorbs the light wave energy emitted from the skin treatment device, a burning sensation appears. By installing the cold compress assembly 300, the skin to be treated or the skin near the skin to be treated can be cold compressed, thereby increasing the comfort of the user when using the skin treatment device.

[0245] Optionally, the skin treatment device is an epilator and / or a skin rejuvenation device, and the light emitting assembly 200 is used to generate light for epilation and / or skin rejuvenation, i.e., the skin treatment device can be used as an epilator and / or a skin rejuvenation device depending on the wavelength setting of the light emitted from the light emitting assembly 200.

The inlet is used for the fan 500 to suck in air, and the outlet is used for discharging the air after heat exchange in the skin treatment device, thereby realizing the airflow flowing through the skin treatment device to dissipate heat inside the skin treatment device.

[0247] 33 to 40 , the light emitting assembly 200 has a light emitting port 201 that emits light. The light transmitting body 310 is located on a side of the filter 220 that is away from the light emitting assembly 200, and a separation space 330 is formed between the light transmitting body 310 and the filter 220. The sealing structure 240 seals the separation space 330 and is located outside the covering space of the light emitting port 201.

[0248] In this embodiment, the sealing structure 240 is a fifth bracket, and the bracket assembly 120 fixes structures such as the light-transmitting body 310. The light emitted from the light-emitting assembly 200 is irradiated to the light-transmitting body 310 after being filtered by the filter 220. The sealing structure 240 seals the gap 330 between the light-transmitting body 310 and the filter 220, thereby avoiding the formation of water mist in the gap 330 which would affect the irradiation of light. In addition, the sealing structure 240 in this embodiment is located outside the covering space of the light-emitting port 201 of the light-emitting assembly 200. In this way, the light emitted from the light-emitting port 201 is not directly irradiated to the sealing structure 240, thereby avoiding the problem that the sealing structure in the prior art is easily aged / carbonized under long-term irradiation of light, and further extending the service life of the sealing structure 240 and the skin treatment device, and preventing powdery foreign matter from affecting the light emission.

[0249] The positioning of the sealing structure 240 outside the covering space of the light-emitting port 201 of the light-emitting assembly 200 may be understood as the positioning of the sealing structure 240 outside the spot irradiated by the light-emitting assembly 200 on the filter 220, so that the light emitted from the light-emitting port is not directly irradiated on the sealing structure 240. This skin treatment device can be used as a hair removal device or a skin rejuvenation device depending on the wavelength setting of the light emitted from the light-emitting assembly 200.

Specifically, in the first embodiment, the sealing structure 240 includes an integrated sealing structure, and the light transmitting body 310 and the filter 220 are both hermetically fitted into the sealing structure.

The inner wall of the insertion groove 241 has an annular sealing rib 242 that abuts against the filter 220. The sealing rib 242 surrounds the opening of the sealing structure, and the sealing rib 242 abuts against the filter 220, thereby further enhancing the sealing effect and preventing water vapor from entering the opening of the sealing structure.

[0252] 37 and 40, the outer circumferential surface of the sealing structure has a restricting groove 243, which is located on the side of the filter 220 that is away from the light emitting assembly 200, the bracket assembly 120 has a mounting groove 101, the filter 220 is mounted in the mounting groove 101 together with the sealing structure, the inner wall of the mounting groove 101 has a protruding restricting protrusion 102, which is inserted into the restricting groove 243 and is restricted and fitted into the restricting groove 243.

After the sealing structure is inserted into the mounting groove, the sealing structure can be regulated and supported by the regulating protrusion 102, thereby ensuring the sealing effect.

[0257] Specifically, as shown in FIG. 34, the regulating protrusion 102 includes a main rib 1021 located on the inner wall of the second mounting plate 1253a and two side ribs 1022 located on the inner wall of the first connection support portion 171 and / or the second connection support portion 172, respectively.

By providing the notch 1023 on the regulating protrusions 102, the sealing structure can be released, which is advantageous for inserting the sealing structure into the chamber of the third bracket 1253, and the size of the regulating protrusions 102 in the insertion direction of the sealing structure is too long, which avoids the contact area with the sealing structure being too large and the resistance being too large, i.e., the provision of the notch 1023 makes assembly easier.

[0259] In this embodiment, the installation process of the sealing structure, the filter 220 and the light transmitting body 310 is described as follows. In step 1, the sealing structure is covered by the light transmitting body 310.

In step 3, the filter 220 is inserted into the insertion groove 241 of the sealing structure. In step 4, the notch of the installation groove is sealed by the fourth bracket 191, thereby fixing the sealing structure, the filter 220 and the light transmitting body 310.

The regulating protrusion 102 can play a regulating role against the first sealing structure 246 and the second sealing structure 247.

[0274] 41 to 43, the restricting protrusion 102 is semi-annular, and the side of the second sealing structure 247 facing the first sealing structure 246 has a semi-annular protrusion 2471. The semi-annular restricting protrusion 102 and the semi-annular protrusion 2471 surround the covering space of the light emitting port 201, and the gap between the first sealing structure 246 and the second sealing structure 247 is semi-annular and matches the shape of the restricting protrusion 102, and the semi-annular protrusion 2471 abuts against a part of the surface of the first sealing structure 246. In this way, the semi-annular protrusion 2471 and the restricting protrusion 102 cooperate to realize sealing between the first sealing structure 246 and the second sealing structure 247.

[0275] 41 , the side of the second sealing structure 247 facing the light emitting assembly 200 has an annular sealing rib 242, which abuts against the filter 220. In this manner, the sealing rib 242 can ensure a reliable seal between the second sealing structure 247 and the filter 220.

[0276] In the second embodiment, an insertion groove 241 is provided on the side of the second sealing structure 247 facing the light emitting assembly 200, and the filter 220 is inserted into the insertion groove 241. The insertion groove 241 allows the filter 220 and the second sealing structure 247 to be connected by an insertion method, which makes the assembly easy.

[0277] In one embodiment not shown, the second sealing structure 247 is completely disposed on the side of the filter 220 facing away from the light-emitting assembly 200, and the second sealing structure 247 and the filter 220 are in close contact with each other, thus similarly realizing sealing between the second sealing structure 247 and the filter 220.

[0278] As shown in FIG. 46, in one embodiment, the phototherapy lamp 900 may be a first sub-light-emitting assembly, and the light-emitting assembly 200 may be a second sub-light-emitting assembly, in which the first sub-light-emitting assembly is used to emit a first light ray toward the light-transmitting body 310 so as to phototreat the skin, by the light-transmitting body 310 emitting at least a portion of the first light ray through the emission surface 312 and the light emission outlet 11, thereby the skin treatment device has the role of a phototherapy device, i.e., the first sub-light-emitting assembly is a phototherapy assembly. The second sub-light-emitting assembly is used to emit a second light beam toward the light-transmitting body 310 so that the light-transmitting body 310 emits at least a portion of the second light beam through the emission surface 312 and the light emission outlet 11 to perform hair removal and / or skin rejuvenation on the skin, whereby the skin treatment device has the role of an epilator and / or a skin rejuvenation device, i.e., the second sub-light-emitting assembly is a hair removal assembly, or a skin rejuvenation assembly, or an assembly combining hair removal and skin rejuvenation functions.

[0279] Specifically, the skin treatment device can not only perform phototherapy on the skin, but also perform hair removal and / or skin rejuvenation on the skin, the first light beam and the second light beam of the skin treatment device in the present application can both be emitted from the emission surface 312, and the first light beam and the second light beam emitted from the emission surface 312 and the light emission port 11 can act on the same skin site at the same time, so that the skin treatment device in the present application can perform different skin care on the same skin site simultaneously or sequentially, that is, the skin treatment device in the present application can perform phototherapy while hair removal on the skin site, and can also timely perform phototherapy on the hair-removed skin site, improving the usage experience. As can be seen from the above, the skin treatment device in the present application has a relatively good experience, and solves the problem that the skin treatment device in the prior art cannot perform hair removal and phototherapy on the same skin site at the same time, resulting in a relatively poor usage experience.

[0280] In addition, the conventional skin treatment device needs to provide a light transmission area for the second light beam on the light exit end surface of the casing assembly, and the light transmission area for the second light beam necessarily occupies a part of the light exit end surface, so the size of the exit port is limited to the light transmission area for the second light beam. The first light beam and the second light beam are both emitted from the exit surface 312 and the light exit port 11 of the present application, the light transmission area for the second light beam is omitted, the size of the light exit port 11 is not limited, and it is further advantageous to increase the light exit port 11 and the exit surface 312, that is, to increase the proportion of the exit surface 312 and the light exit port 11 in the light exit end surface 12 of the casing assembly 100 (for example, it can reach 90% or more), and the light exit end surface 12 is the surface where the light exit port 11 in the casing assembly is located, and thus it is advantageous to increase the light exit effective area on the light exit end surface 12.

[0281] Specifically, the light-transmitting body 310 is a light-transmitting crystal, and the material of the light-transmitting crystal is at least one of sapphire, quartz glass, and quartz crystal. Sapphire has a good skin-friendly feel, and when combined with a cooling member, sapphire can reach a low temperature close to 0 degrees, and can bring the skin temperature near the light outlet 11 as close to the freezing point as possible, greatly relieving pain accompanied by a burning sensation on the skin, and preventing skin damage from a short-term contact. The combination of sapphire and a cooling member means that the cooling member is thermally connected to the sapphire so that the cooling member cools the sapphire.

[0282] Optionally, the second sub-light emitting assembly is an IPL (Intense Pulsed Light) light emitting light source assembly, whereby the second light beam is a strong pulsed light, also called pulsed strong light, and the strong pulsed light is a broad spectrum light formed by focusing and filtering a light source with a very high intensity, and the wavelength of the IPL is often 400nm to 200nm, and different wavelengths have different effects. For example, when the wavelength of the IPL is 690nm to 1200nm, it mainly has a hair removal effect by utilizing the photothermolysis principle of the strong pulsed light. Since the melanocytes in the hair follicle can selectively absorb light of a specific wavelength band, and the IPL light can penetrate the epidermis and directly reach the hair follicle in the dermis, the light energy is absorbed by the melanocytes in the hair follicle in the dermis and converted into heat energy, which increases the temperature of the hair follicle, and when the temperature of the hair follicle is high enough, irreversible destruction occurs in the hair follicle structure, and the destroyed hair follicle will naturally fall off after a certain period of time, thereby slowing down hair growth in a short period of time and even stopping it from growing. When the wavelength of the IPL is 560nm-640nm, it mainly has the effect of skin rejuvenation, or the second sub-light-emitting assembly is a laser light-emitting assembly, whereby the second light beam is a laser beam, and hair removal is realized by the laser.

[0283] Optionally, the first light beam includes at least one of red light, green light, and yellow light, where the green light has a wavelength of 450 nm to 490 nm, the yellow light has a wavelength of 567 nm to 607 nm, and the red light has a wavelength of 620 nm to 660 nm.

[0284] For example, the first light beam contains LED (Light Emitting Diode) light, utilizing the cold light emitted from a narrow spectrum light source, converting light energy into cellular energy without generating high heat and burning the skin, making it a safe beauty method. The LED red light waveband can promote whitening and skin rejuvenation, fade spots, and remove wrinkles, the LED green light waveband can promote deep sterilization and balance oil and fat, the LED orange light waveband can replenish cellular energy, strengthen muscles, improve loosening, etc., and the LED blue light waveband is absorbed by the skin and has a soothing effect, which helps to fade pigmentation spots and show a brighter skin color, and this soothing effect also has an anti-inflammatory effect and can relax the skin surface.

[0285] In one embodiment, the light-transmitting body 310 further includes a light-entering surface 313 disposed opposite the light-exiting surface 312, and the second sub-light-emitting assembly is used to emit a second light beam toward the light-entering surface 313.

[0286] Specifically, the second sub-light-emitting assembly includes a second light-emitting section 2521 for emitting a second light ray, and the second light-emitting section 2521 is disposed opposite the light-entering surface 313 so that the second light ray emitted from the second light-emitting section 2521 enters the light-transmitting body 310 via the light-entering surface 313 and exits via the light-exiting surface 312.

[0287] In one embodiment, the light-transmitting body 310 further includes a side portion 314 connected between the light-emitting surface 312 and the light-entering surface 313, and the first sub-light-emitting assembly is used to emit a first light beam toward the side portion 314.

[0288] Specifically, the side portion 314 includes a first side 3141, and the first sub-light-emitting assembly includes a first light-emitting portion 31 for emitting a first light ray, and the first light-emitting portion 31 is positioned opposite the first side 3141 so that the first light ray enters the light-transmitting body 310 via the first side 3141.

[0289] The first sub-light-emitting assembly and the second sub-light-emitting assembly are respectively installed in different orientations of the light-transmitting body 310, so that the incident orientations of the first light beam and the second light beam are different, and the exit paths of the first light beam and the second light beam through the light-transmitting body 310 are also different, but the exit surface is the same, so that the first light beam and the second light beam can realize the superposition of different functions of the skin treatment device, and the first sub-light-emitting assembly and the second sub-light-emitting assembly do not affect each other in structure. For example, both the first sub-light-emitting assembly and the second sub-light-emitting assembly can be turned on to realize the superposition of the phototherapy and the hair removal and / or skin rejuvenation functions. Only the first sub-light-emitting assembly can be turned on to realize the phototherapy function, and only the second sub-light-emitting assembly can be turned on to realize the hair removal and / or skin rejuvenation function.

[0290] Specifically, the side portion 314 includes a plurality of side surfaces connected in order, the plurality of side surfaces including the first side surface 3141, and at least one of the other side surfaces of the plurality of side surfaces except the first side surface 3141 is provided with a reflective film so that the diffuse reflection phenomenon can occur on the side surface of the diffuse reflection surface, or at least one of the other side surfaces of the plurality of side surfaces except the first side surface 3141 is a diffuse reflection surface, for example, at least one side surface is a rough surface having a fine structure so as to form a diffuse reflection surface. By providing a reflective film on the side surface or making the side surface a diffuse reflection surface, the light beam incident on the light transmitting body 310 is diffusely reflected and / or reflected, and then emitted through the exit surface 312, thereby further increasing the light exit rate, thereby reducing the loss of the first light beam and / or the second light beam. In addition, the diffuse reflection action of the diffuse reflection surface can further increase the light exit uniformity and softness, and ensure the light exit rate.

[0291] Specifically, the reflective film may be a metallic reflective film or an all-dielectric reflective film, or may be a reflective film that is a combination of a metallic reflective film and an all-dielectric reflective film.

[0292] Optionally, the thickness of the reflective film is d, and satisfies 0.1 mm≦d≦0.2 mm. The relatively thin thickness of the reflective film can realize light reflection and does not affect the heat dissipation of the light transmitting body 310.

[0293] Optionally, the side portion 314 includes four side surfaces that are connected in sequence, and preferably, the light-transmitting body 310 is a rectangular parallelepiped. Alternatively, the light-transmitting body 310 is a cylindrical body or a prism body.

[0294] Alternatively, the exit surface 312 is a rectangular plane, or a circular plane, or a circular arc surface, the light entrance surface 313 is a rectangular plane, or a circular plane, or a circular arc surface, and the side surface is a rectangular plane, or a circular plane, or a circular arc surface. For example, the light entrance surface 313 in FIG. 21 is a circular arc surface, i.e., the cross section of the light entrance surface 313 in FIG. 21 is a circular arc surface. The light entrance surface 313 in FIG. 22 is a folded surface, which is composed of three planes, i.e., the cross section of the light entrance surface 313 in FIG. 22 is a trapezoid. The light entrance surface 313 in FIG. 23 is composed of two planes, i.e., the cross section of the light entrance surface 313 in FIG. 23 is V-shaped, and the exit surface 312 and the first side surface 3141 in FIG. 24 are rectangular planes. It should be noted that the light entrance surface 313 may be a folded surface composed of two, three, or even more planes or curved surfaces. The light-transmitting body 310 in FIG. 24 is a triangular prism having a top surface as a first side surface 3141, two of whose side surfaces are a light entrance surface 313 and a light exit surface 312, respectively.

[0295] In one embodiment, the exit surface 312 is located at the light exit 11 .

[0296] Specifically, the surface on which the emission surface 312 and the light outlet 11 are located are in the same plane, or at least a portion of the emission surface 312 is disposed so as to protrude toward the outside of the casing assembly 100 beyond the surface on which the light outlet 11 is located.

[0297] Specifically, the inner wall of the light outlet 11 is in close contact with the side surface portion 314 of the light transmitting body 310 .

[0298] In one embodiment, the light entrance surface 313 is a diffuse reflection surface so that at least a portion of the first light ray irradiated into the optically transparent body 310 is emitted from the light exit surface 312 by the diffuse reflection effect of the light entrance surface 313 .

[0299] Specifically, a plurality of protrusions 3131 are provided on the light entrance surface 313, and the protrusions 3131 are provided so as to protrude in a direction away from the light exit surface 312 so that the light entrance surface 313 becomes a diffuse reflection surface. One protrusion 3131 constitutes one diffuse reflection dot. Furthermore, the diffuse reflection action of the diffuse reflection surface formed by the plurality of protrusions 3131 allows for better light guide and diffuse reflection, further improving the light exit uniformity and softness of the light beam, and ensuring the light exit rate.

[0300] Specifically, the protrusions 3131 have a micro-convex structure so as to form a rough surface.

[0301] Specifically, the protrusion 3131 is formed by an etching process. The etching process refers to a process of removing the film layer not masked by the etching resist to obtain exactly the same pattern on the film as on the etching resist film. Etching is performed by using a chemical method, a physical method, or a combination of a chemical method and a physical method to selectively remove a part of the film layer not masked by the etching resist to obtain exactly the same pattern on the film as on the etching resist film. Etching techniques are mainly divided into dry etching and wet etching. Dry etching mainly uses reactive gas and plasma to etch, while wet etching mainly uses chemical reaction between chemical reagent and the material to be etched to etch. The etching process is a well-known technique in the field, and the technique is mature in the relevant industrial chain, which is easy to further reduce the manufacturing cost.

[0302] Specifically, the multiple protrusions 3131 are arranged on the light incident surface 313 at intervals.

[0303] Optionally, the shape of the projection of the protrusion 3131 onto the light entrance surface 313 is circular, or polygonal, or elliptical, or irregular.

[0304] Alternatively, the value range of the spacing between any two adjacent protrusions 3131 is 0.001 mm to 0.2 mm, and for example, the spacing may be 0.001 mm, or 0.002 mm, or 0.005 mm, or 0.01 mm, or 0.05 mm, or 0.1 mm, or 0.15 mm, or 0.2 mm.

[0305] Alternatively, the diameter or equivalent diameter of the projection 3131 onto the light entrance surface 313 may range from 20 micrometers to 50 micrometers, for example, the diameter or equivalent diameter may be 20 micrometers, or 25 micrometers, or 30 micrometers, or 36 micrometers, or 40 micrometers, or 44 micrometers, or 50 micrometers.

[0306] Optionally, the value range of the protrusion height of the protrusion portion 3131 is 5 micrometers to 15 micrometers, for example, the protrusion height is 5 micrometers, or 6 micrometers, or 8 micrometers, or 10 micrometers, or 11 micrometers, or 13 micrometers, or 15 micrometers.

[0307] Optionally, the multiple sides include a second side 3142 disposed opposite to the first side 3141. The light enters the light transmitting body 310 through the first side 3141, that is, the first side 3141 is closer to the first sub-light emitting assembly, so the amount of light closer to the first sub-light emitting assembly is larger, and the amount of light leaving the first sub-light emitting assembly is smaller. As shown in FIG. 19, the distribution density of the protrusions 3131 gradually increases in the direction from the first side 3141 to the second side 3142. As for the light on the diffuse reflection surface leaving the first sub-light emitting assembly that has reached the light entrance surface 313, the amount of light is small, so the distribution density of the scattering dots on the diffuse reflection surface can be increased to increase the probability of the light being scattered, thereby increasing the probability of the light being emitted from the exit surface 312 of the light transmitting body 310, increasing the utilization rate of the light, and improving the phototherapy efficiency. 19 indicates a direction from the first side surface 3141 to the second side surface 3142. Alternatively, the plurality of protrusions 3131 are uniformly distributed on the light entrance surface 313 as shown in FIG.

[0308] In a specific implementation process, the heat generated by the first sub-light-emitting assembly is rapidly diffused to the cooling sheet 800 through the light-transmitting body 310, thereby lowering the light-transmitting body 310 to a low temperature close to 0 degrees, and further bringing the skin temperature near the light outlet 11 as close to the freezing point as possible, greatly relieving the pain caused by the burning sensation on the skin and preventing skin damage from brief contact.

[0309] Specifically, the cooling sheet 800 is placed opposite the second side surface 3142 of the optically transparent body 310 .

[0310] In one embodiment, the first sub-light-emitting assembly includes a first light-emitting unit for emitting a first light beam, the first light-emitting unit includes a circuit board and a plurality of light-emitting bodies, the plurality of light-emitting bodies are attached to the circuit board, and the light beam generated from at least some of the plurality of light-emitting bodies is the first light beam. The surface of the circuit board on which the plurality of light-emitting bodies are attached is disposed opposite to the first side surface 3141.

[0311] Specifically, the light emitter is a light emitting wafer or a lamp bead, and the light emitting wafer or the lamp bead is integrated on a circuit board, which can realize the centralization of the light source, and can integrate multiple light sources in a small area, for example, up to several tens of LED lamps, thereby improving the irradiance.

[0312] Specifically, the circuit board is placed opposite the first side 3141 so that light rays generated from at least some of the multiple light-emitting elements are incident on the light-transmitting body 310 through the first side 3141.

[0313] Alternatively, the circuit board may be a printed circuit board (PCB) or a flexible printed board (FPB). A printed circuit board is a support for electronic devices and also a carrier for connecting each electronic device to each other, and is made using electronic printing methods, so it is called a "printed" circuit board. A flexible circuit board is a type of printed circuit board, and is manufactured using polyimide or polyester film as a base material. It is a highly reliable and excellent flexible printed circuit board, and has the characteristics of high wiring density, light weight, thin thickness, and good bending property.

[0314] Alternatively, the light-emitting wafer may be a light-emitting diode (Light-emitting Diode) wafer. The light-emitting wafer may include eutectic wafers of different light-emitting colors, for example, the light-emitting wafer includes at least one of a red LED eutectic wafer, a green LED eutectic wafer, a blue LED eutectic wafer, and a eutectic semiconductor wafer. Or, the light-emitting wafer is a red-green-blue combination eutectic wafer. Any one of the eutectic wafers can be mounted to a eutectic pad by eutectic welding to form an electrical connection with an ITO (Indium Tin Oxide) film circuit layer through the eutectic pad, and the ITO film circuit layer is bonded around the surface or on the side of the substrate. The positive and negative electrode pads of the light-emitting eutectic wafer are both located below the wafer, so that they can be connected to the substrate using Direct Attach (DA). The top inverted flip structure allows both the front and side of the top to have a relatively high light output.

[0315] Optionally, the lamp bead is an LED lamp bead, and the LED lamp bead mainly includes components such as a chip, a holder, a gold wire and a transparent resin, and the holder includes a substrate, a heat dissipation base and a pin.

[0316] In one embodiment, the circuit board includes a two-layer structure, and the plurality of light emitters are integrated between the two-layer structure. The mounting case 62 is covered on the outer periphery of the two-layer structure.

[0317] Specifically, the circuit board is a two-layer circuit board, which includes a first layer and a second layer, both of which have copper cladding and wiring, and wiring holes that allow the lines between the two layers to be conductive and form the required mesh connection therebetween.

[0318] In one embodiment, the multiple light emitters are divided into a first light-emitting unit including at least one light emitter and a second light-emitting unit including at least one light emitter, and the color of light emitted from the light emitter of the first light-emitting unit is different from the color of light emitted from the light emitter of the second light-emitting unit.

[0319] Specifically, the first sub-light-emitting assembly may be an instruction light source for instructing the user on the operation mode of the skin treatment device. For example, the first sub-light-emitting assembly has a first light-emitting mode, a second light-emitting mode, and a third light-emitting mode, and when the first sub-light-emitting assembly is in the first light-emitting mode, the light-emitting body of the first light-emitting unit emits light and the light-emitting body of the second light-emitting unit does not emit light. When the first sub-light-emitting assembly is in the second light-emitting mode, the light-emitting body of the first light-emitting unit does not emit light, but the light-emitting body of the second light-emitting unit emits light. When the first sub-light-emitting assembly is in the third light-emitting mode, the light-emitting body of the first light-emitting unit and the light-emitting body of the second light-emitting unit emit light alternately.

[0320] Optionally, the light emitter of the first light-emitting unit is a red light emitter, that is, the color of the light emitted from the light emitter of the first light-emitting unit is red.

[0321] Optionally, the light emitter of the second light-emitting unit is an orange light emitter, that is, the color of the light emitted from the light emitter of the second light-emitting unit is orange.

[0322] Optionally, when the first light-emitting unit includes a plurality of light-emitting bodies and the second light-emitting unit includes a plurality of light-emitting bodies, the distribution direction of the plurality of light-emitting bodies of the first light-emitting unit is parallel to the distribution direction of the plurality of light-emitting bodies of the second light-emitting unit.

[0323] In one embodiment, the first sub-light-emitting assembly further includes a light-uniformizing plate, which is disposed between the first light-emitting section and the light-transmitting body 310 such that the first light ray emitted from the first light-emitting section passes through the light-uniformizing plate and then enters the light-transmitting body 310.

[0324] Specifically, the light uniformizing plate is disposed between the circuit board and the light transmitting body 310 .

[0325] In one embodiment, the second sub-light-emitting assembly further includes a light-reflecting member that surrounds the second sub-light-emitting assembly to form a light-reflecting space, and the second light-emitting portion is disposed within the light-reflecting space to reduce leakage of the second light ray, and the second light-emitting portion is positioned on the side of the light-reflecting member facing the light-transmitting body 310, so that the light-reflecting member reflects at least a portion of the second light ray toward the light-transmitting body 310.

[0326] Specifically, the second sub-light-emitting assembly further includes a filter 220, which is disposed on the side of the light reflecting member facing the light transmitting body 310 so as to be located on the exit light path of the light reflecting member. The filter 220 filters out light (e.g., ultraviolet light) harmful to the human body in the strong pulsed light, and makes the target light beam from which the harmful light has been filtered act on the human skin, and the target light beam can penetrate the epidermis and directly reach the hair follicle in the dermis, and be absorbed by the melanocytes in the hair follicle, thereby increasing the temperature of the hair follicle, destroying the hair follicle structure, and achieving the effect of retarding hair growth.

[0327] Optionally, the second light-emitting part is a light-emitting lamp bulb, for example, the light-emitting lamp bulb is an IPL lamp bulb.

[0328] Optionally, the light reflecting member is an arc-shaped structure, for example, the light reflecting member is an arc-shaped case.

[0329] Optionally, the light reflecting member is a light reflecting cup.

[0330] Specifically, the light reflecting member has a light reflecting opening 422 communicating with the light reflecting space, the filter 220 is connected to or abuts the light reflecting member, and the filter 220 is disposed at the light reflecting opening 422 .

[0331] In one embodiment, the first sub-light-emitting assembly is multiple, and the multiple first sub-light-emitting assemblies are all used to emit a first light beam toward the light-transmitting body 310, such that the light-transmitting body 310 emits at least a portion of the first light beam of each first sub-light-emitting assembly through the emission surface 312 and the light emission outlet 11 to phototreat the skin.

[0332] Specifically, the side portion 314 includes a plurality of first side surfaces 3141, and the first light emitting portions of the plurality of first sub-light emitting assemblies are arranged opposite to the plurality of first side surfaces 3141 in a one-to-one correspondence, so that the first light ray of each first sub-light emitting assembly enters the light-transmitting body 310 through the corresponding first side surface 3141.

[0333] Optionally, the colors of the first light beams emitted from the plurality of first sub-light-emitting assemblies are different. In a specific implementation, at least one of the first sub-light-emitting assemblies can be turned on to perform light treatment on the skin, thus achieving the purpose of different light treatment effects.

[0334] Optionally, different types and paths of the first light rays emitted from multiple first sub-light-emitting assemblies are advantageous for realizing more skin care functions and can reduce the interference between different first light paths.

[0335] As shown in Figures 47 to 58, the internal chamber of the casing assembly 100 communicates with the outside through the air port portion 12. Specifically, the casing assembly 100 has a longitudinal direction, and the outer wall surface of the casing assembly 100 includes a recessed portion 115. Along the longitudinal direction of the casing assembly 100, the casing assembly 100 has a front end and a rear end. When treating skin using a skin treatment device, the front end of the casing assembly 100 is used to be placed toward or close to the skin, and in the direction from the front end to the rear end of the casing assembly 100, the wall surface of the recessed portion 115 is formed into a first recessed portion 115 that is connected to each other. The casing assembly 100 includes a wall portion 116 and a second wall portion 117, the first wall portion 116 being located on a side of the second wall portion 117 closer to the front end of the casing assembly 100, and in a direction from the front end to the rear end of the casing assembly 100, the first wall portion 116 is disposed gradually closer to the internal chamber of the casing assembly 100 to form a recess portion 115, and at least a portion of the first wall portion 116 and at least a portion of the second wall portion 117 are used to form the gripping area 16, and the air port portion 12 is located outside the gripping area 16.

[0336] 49 and 50, the first wall 116 is gradually disposed closer to the internal chamber of the casing assembly 100 in the direction from the front end to the rear end of the casing assembly 100, which means that the first wall 116 is gradually recessed inward, i.e., the internal chamber of the casing assembly 100 becomes gradually smaller. In this way, a gripping area 16 for a user to grip can be formed.

[0337] In addition, the recess portion 115 and the first wall portion 116 may be configured as part of the circumferential direction of the outer wall surface of the casing assembly 100. For example, the recess portion 115 and the first wall portion 116 may be formed in the back panel 14, and the recess portion 115 and the first wall portion 116 may be configured to be installed around the circumferential direction of the outer wall surface of the casing assembly 100. In other words, the first wall portion 116 and the second wall portion 117 are formed in all of the panel 21, the back panel 14, the first side panel 15 and the second side panel 22 of the casing assembly 100.

[0338] The direction of the arrows in Figures 47 and 48 is from the rear end to the front end of the casing assembly 100.

[0339] The skin treatment device of the present application forms a recess 115 on the outer wall surface of the casing assembly 100, and forms a gripping area 16 in at least a portion of the first wall 116 and at least a portion of the second wall 117 of the recess 115, thereby guiding the user to grip the gripping area 16 during use, and by positioning the first wall 116 gradually closer to the internal chamber of the casing assembly 100 in the direction from the front end to the rear end of the casing assembly 100, the user's comfort when gripping the device can be easily increased.

[0340] Furthermore, by placing the casing air port portion 12 outside the gripping area 16, it is possible to avoid blocking the suction port when the user grips it with their hand, thereby solving the problem with skin treatment devices in conventional technology that the part that the user grips with their hand tends to block the suction port, which can easily affect the heat dissipation effect.

[0341] In one embodiment, the first mounting configuration of the second wall 117 is that the second wall 117 is mounted gradually away from the interior chamber of the casing assembly 100 in a direction from the front end to the rear end of the casing assembly 100. The second mounting configuration of the second wall 117 is that the second wall 117 is a smooth wall, which means that the second wall 117 does not substantially protrude or recess inward in a direction from the front end to the rear end of the casing assembly 100. The third installation form of the second wall portion 117 is that, in the direction from the front end to the rear end of the casing assembly 100, the second wall portion 117 includes a front half and a rear half, the front half of the second wall portion 117 is a smooth wall portion, and the rear half of the second wall portion 117 is installed gradually away from the internal chamber of the casing assembly 100 in the direction from the front end to the rear end of the casing assembly 100, where this smooth wall portion means that, in the direction from the front end to the rear end of the casing assembly 100, the front half of the second wall portion 117 barely protrudes or recesses inward.

[0342] By forming at least a portion of the second wall portion 117 as a smooth wall portion, it is possible to grip the device appropriately backward when gripping it.

[0343] Optionally, the first wall portion 116 is a smoothly curved surface, the second wall portion 117 is a smoothly curved surface, and the first wall portion 116 and the second wall portion 117 are connected with a smooth transition.

[0344] In one embodiment, along the length of the casing assembly 100 , the air outlet 12 is located on the side of the gripping area 16 closer to the front end of the casing assembly 100 .

[0345] The relatively large heat generating structure of the skin treatment device (e.g., the light emitting lamp bulb and the cooling member 702) is basically installed at the front end of the casing assembly 100, and the air outlet portion 12 is installed on the side closer to the front end of the casing assembly 100 in the holding area 16, thereby shrinking the air path design and improving the heat dissipation effect.

[0346] Specifically, the area on the outer wall surface of the casing assembly 100 where the air outlet portion 12 is located is the ventilation area 17 , that is, the ventilation area 17 is located on the side of the gripping area 16 closer to the front end of the casing assembly 100 .

[0347] In one embodiment, the gripping area 16 is located at the longitudinal center of the casing assembly 100, or the gripping area 16 is located close to the longitudinal center of the casing assembly 100. In this manner, it is easier for the user to grip with less effort.

[0348] In one embodiment, the housing 110 further includes an air outlet 12, the air outlet 12 including a casing outlet 1201 and an intake 1202, and at least a part of the casing outlet 1201 is located on the side of the intake 1202 away from the gripping region 16. As can be understood, the light emitting assembly 200 and the bracket structure of the supporting light emitting assembly 200 and other components are installed in front of the gripping region 16, the fan assembly 300 may be installed corresponding to the gripping region 16, and the fan assembly 300 may be installed on the rear side of the gripping region 16. In the present application, the intake 1202 is installed closer to the gripping region 16, so that the intake 1202 can be closer to the fan 500, thereby shrinking the intake air passage or making the intake air passage relatively short, which makes it easier to improve the heat dissipation effect.

[0349] In one embodiment, the casing assembly 100 includes a first casing 10, which includes a back panel 14 and two first side panels 15, each of which is connected to two long sides of the back panel 14, and each long side of the back panel 14 has two ends along the longitudinal direction of each long side of the back panel 14, and the distribution direction of the two ends of each long side of the back panel 14 is the same as the distribution direction of the front end and the rear end of the casing assembly 100.

[0350] Specifically, both the recess 115 and the suction section 1202 are disposed on the back plate 14 , and at least a portion of the casing blowing section 1201 is disposed on the back plate 14 .

[0351] Specifically, the first distribution form of the casing blowing part 1201 is that the casing blowing part 1201 is installed on the back plate 14 and is located on the side of the suction part 1202 away from the gripping area 16.

[0352] Specifically, the second distribution form of the casing blowing section 1201 is such that the casing blowing section 1201 includes a first blowing section 1211 and a second blowing section 1212, the first blowing section 1211 is installed on the back panel 14, the second blowing section 1212 is installed on one of the first side panels 15, the first blowing section 1211 is located on the side away from the gripping area 16 of the suction section 1202, and at least a part of the second blowing section 1212 is located on the side away from the gripping area 16 of the suction section 1202.

[0353] Specifically, the third distribution form of the casing blowing section 1201 is that the casing blowing section 1201 includes a first blowing section 1211 and two second blowing sections 1212, the first blowing section 1211 is installed on the back plate 14, the two second blowing sections 1212 are installed on the two first side plates 15, respectively, the first blowing section 1211 is located on the side away from the gripping area 16 of the suction section 1202, and at least a part of each of the second blowing sections 1212 is located on the side away from the gripping area 16 of the suction section 1202. In this way, by adding the second blowing section 1212 to the first side plate 15, the blowing area can be increased and a better blowing structure can be easily installed in the casing assembly 100, thereby improving the heat dissipation effect.

[0354] In one embodiment, the outer wall surface of the casing assembly 100 further includes a protuberance 13, which is located on the side of the recess 115 closer to the front end of the casing assembly 100 along the longitudinal direction of the casing assembly 100 (other descriptions of similar positional relationships in the specification may be abbreviated to the front side). In the direction from the front end to the rear end of the casing assembly 100, the wall surface of the protuberance 13 includes a third wall 1301 and a fourth wall 1302 connected to each other, i.e., the third wall 1301 is located on the side of the fourth wall 1302 closer to the front end of the casing assembly 100, and in the direction from the front end to the rear end of the casing assembly 100, the third wall 1301 is gradually disposed away from the internal chamber of the casing assembly 100, and the fourth wall 1302 is gradually disposed close to the internal chamber of the casing assembly 100, and the fourth wall 1302 is connected to the first wall 116. At least a portion of the air outlet portion 12 is disposed on the raised portion 13 .

[0355] Generally, to the left of the dashed line in FIG. 49 is raised portion 13 and to the right of the dashed line is recessed portion 115 and gripping area 16.

[0356] The raised portion 13 may be configured as a part of the circumferential direction of the outer wall surface of the casing assembly 100. For example, the raised portion 13 may be formed on the back plate 14, and the raised portion 13 may be configured to be installed around the circumferential direction of the outer wall surface of the casing assembly 100. That is, the third wall portion 1301 and the fourth wall portion 1302 are formed on the panel 21, the back plate 14, the first side plate 15, and the second side plate 22 of the casing assembly 100. In this way, by forming the raised portion 13 and installing the air port portion 12, the gripping support role of the gripping area 16 becomes more prominent, and a relatively large ventilation installation area can be formed, thereby facilitating the installation of more ventilation ports 1203.

[0357] Specifically, along the length of the casing assembly 100 , the raised portion 13 is located on the side of the gripping region 16 closer to the front end of the casing assembly 100 .

[0358] In one embodiment, the ridges 13 are formed in the back plate 14 .

[0359] In one embodiment, the suction portion 1202 is located on the ridge 13 .

[0360] When the casing blowing section 1201 is in the first distribution pattern, the casing blowing section 1201 is provided on the raised section 13. When the casing blowing section 1201 is in the second distribution pattern or the third distribution pattern, the first blowing section 1211 is provided on the raised section 13.

[0361] Selectively, at least a portion of the casing blowing section 1201 is provided on the third wall section 1301. That is, when the casing blowing section 1201 is in the first distribution form, at least a portion of the casing blowing section 1201 is provided on the third wall section 1301, and when the casing blowing section 1201 is in the second distribution form or the third distribution form, at least a portion of the first blowing section 1211 is provided on the third wall section 1301.

[0362] Optionally, at least a part of the suction section 1202 is installed on the fourth wall section 1302. By installing the casing blowing section 1201 on the third wall section 1301 and installing the suction section 1202 on the fourth wall section 1302, the direction of the blowing port on the third wall section 1301 and the direction of the opening of the suction port on the fourth wall section 1302 can be made different, thus eliminating or reducing the probability that the hot air discharged through the blowing port on the third wall section 1301 re-enters the casing assembly 100 through the suction port, which is advantageous to improving heat dissipation efficiency.

[0363] In one embodiment, the third wall portion 1301 is a smooth curved surface, the fourth wall portion 1302 is a smooth curved surface, the third wall portion 1301 and the fourth wall portion 1302 are smoothly transitionally connected, and the fourth wall portion 1302 and the first wall portion 116 are smoothly transitionally connected. In this way, the aesthetics can be enhanced.

[0364] In one embodiment, the portion of the casing blowing section 1201 that is installed on the back panel 14 is the designated blowing section 1215, i.e., when the casing blowing section 1201 is in the first distribution form, the entire casing blowing section 1201 is the designated blowing section 1215, and when the casing blowing section 1201 is in the second distribution form or the third distribution form, the first blowing section 1211 is the designated blowing section 1215. The area in which the designated blowing section 1215 is located is the designated blowing area.

[0365] Specifically, along the longitudinal direction of the casing assembly 100, the designated blowing section 1215 is located on the side of the suction section 1202 closer to the front end of the casing assembly 100. In FIG. 52, a broken line L is used as a boundary line, and the left side of the broken line L is the designated blowing section 1215, and the right side of the broken line L is the suction section 1202.

[0366] Specifically, the designated blowing section 1215 includes a plurality of blowing groups, each of which includes a plurality of designated blowing outlets 1216, the plurality of blowing groups being distributed at intervals along a first direction, the plurality of designated blowing outlets 1216 in each blowing group being distributed at intervals along a second direction, and the first direction and the second direction being disposed at an angle.

[0367] Specifically, any three adjacent blowing groups are a first blowing group, a second blowing group, and a third blowing group, respectively, and the multiple designated blowing ports 1216 in the first blowing group and the multiple designated blowing ports 1216 in the second blowing group are installed in one-to-one correspondence, and the multiple designated blowing ports 1216 in the first blowing group and the multiple designated blowing ports 1216 in the third blowing group are installed in one-to-one correspondence, i.e., the multiple designated blowing ports 1216 in the second blowing group and the multiple designated blowing ports 1216 in the third blowing group are installed in one-to-one correspondence.

[0368] Alternatively, each designated outlet 1216 in the first blowing group, the corresponding designated outlet 1216 in the second blowing group, and the corresponding designated outlet 1216 in the third blowing group are located on the same straight line. Alternatively, the straight line on which each designated outlet 1216 in the first blowing group and the corresponding designated outlet 1216 in the second blowing group are located is disposed at an angle to the straight line on which the corresponding designated outlet 1216 in the second blowing group and the corresponding designated outlet 1216 in the third blowing group are located, that is, each designated outlet 1216 in the second blowing group and the corresponding designated outlet 1216 in the first blowing group are disposed to intersect, and each designated outlet 1216 in the second blowing group and the corresponding designated outlet 1216 in the third blowing group are disposed to intersect. The outlets 1216 are also installed crosswise, and thus it is advantageous to install a relatively large number of designated outlets 1216 within a limited designated blowing area, thereby increasing the blowing volume in the designated blowing area; and increasing the blowing volume by installing a relatively large number of designated outlets 1216 can form a dense mesh structure in the designated blowing area compared to increasing the blowing volume by increasing the ventilation area of ​​the designated outlet, thus preventing external foreign objects from entering the casing assembly 100.

[0369] Specifically, the projection of each designated air outlet 1216 onto the first projection plane is a rectangle, the first projection plane is perpendicular to the airflow direction of at least one designated air outlet 1216, and the first diagonals of the projection of the designated air outlets 1216 in each air outlet group onto the first projection plane are on the same straight line. The projection of each designated air outlet 1216 onto the first projection plane has two diagonals, one of which is the first diagonal. The first straight line 191 in FIG. 6 is the straight line on which the first diagonal of the projection of the designated air outlets 1216 in one of the air outlet groups onto the first projection plane is located.

[0370] In one embodiment, the suction unit 1202 includes a plurality of suction groups, each suction group including a plurality of suction ports 1221, the plurality of suction groups being spaced apart and distributed along a third direction, the plurality of suction ports 1221 in each suction group being spaced apart and distributed along a fourth direction, and the third direction and the fourth direction are disposed at an angle.

[0371] Specifically, any three adjacent suction groups are a first suction group, a second suction group, and a third suction group, respectively, and the multiple suction ports 1221 in the first suction group and the multiple suction ports 1221 in the second suction group are installed in one-to-one correspondence, and the multiple suction ports 1221 in the first suction group and the multiple suction ports 1221 in the third suction group are installed in one-to-one correspondence, i.e., the multiple suction ports 1221 in the second suction group and the multiple suction ports 1221 in the third suction group are installed in one-to-one correspondence.

[0372] Alternatively, each suction port 1221 in the first suction group, the corresponding suction port 1221 in the second suction group, and the corresponding suction port 1221 in the third suction group are located on the same straight line. Alternatively, the straight line on which each suction port 1221 in the first suction group and the corresponding suction port 1221 in the second suction group are located and the straight line on which the corresponding suction port 1221 in the second suction group and the corresponding suction port 1221 in the third suction group are located are arranged at an angle, that is, each suction port 1221 in the second suction group and the corresponding suction port 1221 in the first suction group are arranged to intersect, and each suction port 1221 in the second suction group and the corresponding suction port 1221 in the third suction group are arranged to intersect. 1 are installed crosswise, and thus it is advantageous to install a relatively large number of suction ports 1221 within a limited suction area, and further increase the suction volume of the suction area. Furthermore, increasing the suction volume by installing a relatively large number of suction ports 1221 can form a dense mesh structure in the suction area compared to increasing the suction volume by increasing the ventilation area of ​​the suction port, and thus it is possible to prevent external foreign objects from entering the casing assembly 100.

[0373] Specifically, the projection of each suction port 1221 onto the second projection plane is a rectangle, the second projection plane is perpendicular to the airflow direction of at least one suction port 1221, and the second diagonals of the projection of the multiple suction ports 1221 in each suction group onto the second projection plane are on the same straight line. The projection of each suction port 1221 onto the second projection plane has two diagonals, one of which is the second diagonal. The second straight line 192 in FIG. 52 is the straight line on which the second diagonal of the projection of the multiple suction ports 1221 in one of the suction groups onto the second projection plane is located.

[0374] In one embodiment, when the casing blowing section 1201 is in the first distribution form, the casing blowing section 1201 includes a plurality of blowing outlets spaced apart from each other, and in this case, each of the blowing outlets is a designated blowing outlet 1216. When the casing blowing section 1201 is in the second distribution form or the third distribution form, the first blowing section 1211 includes a plurality of first blowing outlets 1213 spaced apart from each other, and each of the first blowing outlets 1213 is a designated blowing outlet 1216, and the second blowing section 1212 includes a plurality of second blowing outlets 1214 spaced apart from each other.

[0375] In one embodiment, the casing outlet section 1201 includes a plurality of vents 1203 spaced apart, and when the casing outlet section 1201 is in a first distribution form, the vents 1203 are a collective term for the intake port 1221 and the outlet, and when the casing outlet section 1201 is in a second or third distribution form, the vents 1203 are a collective term for the intake port 1221, the first outlet 1213, and the second outlet 1214.

[0376] As shown in FIG. 58, along the airflow direction of ventilation opening 1203, ventilation opening 1203 includes an outer air port portion 1203a and an inner air port portion 1203b that are connected and communicate with each other, and the ventilation surface of outer air port portion 1203a is a cross section of outer air port portion 1203a perpendicular to the airflow direction of ventilation opening 1203, and the ventilation surface of inner air port portion 1203b is a cross section of inner air port portion 1203b perpendicular to the airflow direction of ventilation opening 1203.

[0377] The first casing 10 is generally processed using an injection molding technique, and the vent 1203 is made into an outer vent portion 1203a and an inner vent portion 1203b, and the outer vent portion 1203a and the inner vent portion 1203b can be molded using an outer mold portion and an inner mold portion during injection molding. When the length of the vent is constant, molding the vent 1203 using the outer mold portion and the inner mold portion makes it easier to release the outer mold portion and the inner mold portion than to release the vent from the integral injection molding mold.

[0378] Optionally, the ventilation surface of the outer air outlet portion 1203a is smaller than the ventilation surface of the inner air outlet portion 1203b, thus avoiding the interior of the casing assembly 100 from being easily visible, which is advantageous in that it is easier to hide the internal structure within the casing assembly 100 and improve the aesthetic appearance of the skin treatment device; furthermore, making the ventilation surface of the inner air outlet portion 1203b relatively large is also advantageous in demolding the inner mold portion.

[0379] Alternatively, the length of the outer air outlet portion 1203a is shorter than the length of the inner air outlet portion 1203b, and the longitudinal direction of the outer air outlet portion 1203a and the longitudinal direction of the inner air outlet portion 1203b are both the same as the air flow direction of the ventilation hole 1203, i.e., to realize hiding of the internal structure within the casing assembly 100, while making the length of the inner air outlet portion 1203b, which has a relatively large ventilation surface, relatively long, to ensure that the ventilation volume of the ventilation hole 1203 is not too small, i.e., the ventilation hole 1203 has a relatively large ventilation volume.

[0380] Optionally, the ventilation surface of the outer air outlet portion 1203a is gradually increased along the direction from the inner air outlet portion 1203b to the outer air outlet portion 1203a so that the outer air outlet portion 1203a is flared, which is advantageous in that it makes it easier to release the outer mold part.

[0381] In one embodiment, the area on the outer wall surface of the casing assembly 100 where the designated blowing section 1215 is located is the first blowing area, i.e., when the casing blowing section 1201 is in the first distribution form, the area on the outer wall surface of the casing assembly 100 where the casing blowing section 1201 is located is the first blowing area, and when the casing blowing section 1201 is in the second distribution form or the third distribution form, the area on the outer wall surface of the casing assembly 100 where the first blowing section 1211 is located is the first blowing area, and the area on the outer wall surface of the casing assembly 100 where the second blowing section 1212 is located is the second blowing area. The area on the outer wall surface of the casing assembly 100 where the outer wall surface suction section 1202 is located is the suction area.

[0382] Specifically, the fan 500 is installed in the gripping area 16 by locating the intake of the fan 500 corresponding to the gripping area 16, and thus the structure between the suction area and the fan 500 is relatively small and the wind resistance is relatively small, while the structure between the blowing area and the fan 500 is relatively large and the wind resistance is relatively large. When the installation area of ​​the air port is limited, the area of ​​the suction area is made smaller than the area of ​​the first blowing area, i.e., the area of ​​the first blowing area is made relatively large, which makes it easy to increase the speed of the blowing airflow (heat dissipating airflow) with a relatively large wind resistance in the casing assembly 100, thereby improving the heat dissipation efficiency.

[0383] Specifically, the designated blowing section 1215 includes a plurality of designated blowing outlets 1216 that are spaced apart, the suction section 1202 includes a plurality of suction inlets 1221 that are spaced apart, and the plurality of designated blowing outlets 1216 include a first portion of designated blowing outlets, i.e., the designated blowing section 1215 includes a first portion of designated blowing outlets, the first portion of designated blowing outlets include at least one designated blowing outlet 1216, the plurality of suction inlets 1221 include a first portion of suction inlets, and the first portion of suction inlets include at least one suction inlet 1221, and the ventilation surface of the designated blowing outlets 1216 of the first portion of designated blowing outlets on the outer wall surface of the casing assembly 100 is smaller than the ventilation surface of the suction inlets 1221 of the first portion of suction inlets on the outer wall surface of the casing assembly 100.

[0384] In addition, in the above-given embodiments, the casing air outlets 1201 are all installed on the back panel and located in the non-gripping area. When the user operates the device while holding it, air can be blown out to the back side, avoiding air blowing onto the human body, thereby improving the user experience.

[0385] It should be noted that the casing assembly 100 may be formed in other forms, for example, including a left casing and a right casing, but even in this case, the casing assembly after assembly is completed still includes the panel 21 and the back panel 14, where the panel 21 generally means a side panel facing the user's face during use, and the panel 21 may be provided with control buttons, display information, etc., and the back panel 14 generally means a side panel opposite the user's face during use. That is, the casing assembly 100 includes the panel 21 and the back panel 14 that are installed opposite to each other, the recessed portion 115 is installed on the back panel 14, and at least a part of the casing outlet portion 1201 is installed on the back panel 14.

[0386] Specifically, the distribution direction of the panel 21 and the back plate 14 is perpendicular to the longitudinal direction of the casing assembly 100 .

[0387] Specifically, in the direction from the front end to the rear end of the casing assembly 100 , the first wall portion 116 is disposed progressively closer to the panel 21 .

[0388] Specifically, when the second wall portion 117 uses the first installation form, the second wall portion 117 is installed gradually farther away from the panel 21 in the direction from the front end to the rear end of the casing assembly 100.

[0389] Specifically, in the direction from the front end to the rear end of the casing assembly 100, the third wall portion 1301 is disposed gradually farther away from the panel 21, and the fourth wall portion 1302 is disposed gradually closer to the panel 21.

[0390] In one embodiment, the casing assembly 100 includes a first casing 10 and a second casing 20 that are detachably connected, the first casing 10 includes a back panel 14, the second casing 20 includes a panel 21, and the air outlet section 12 is installed in the first casing 10.

[0391] In one embodiment, along the longitudinal direction of the casing assembly 100, the casing assembly 100 includes a first case segment 30, a portion of the first casing 10 in the first case segment 30 is a first case part 31, a portion of the second casing 20 in the first case segment 30 is a second case part 32, and the air port part 12 is located in the first case part 31.

[0392] Specifically, the portion of the back panel 14 in the first case portion 31 is the first back panel portion 1401, and the first case portion 31 further includes two first side panel portions 1501, each of which is connected to one of the two long sides of the first back panel portion 1401, and each of the first side panel portions 1501 is detachably connected to the second casing 20.

[0393] Specifically, the two first side plate portions 1501 and the two first side plates 15 are installed in a one-to-one correspondence, and the portion of each first side plate 15 in the first case portion 31 is the corresponding first side plate portion 1501. Each of the first side plates 15 is detachably connected to the second casing 20.

[0394] Specifically, the distribution direction of the two first side plates 15 is perpendicular to the longitudinal direction of the casing assembly 100, and the distribution direction of the two first side plates 15 is perpendicular to the distribution direction of the panel 21 and the back plate 14.

[0395] Specifically, the air outlet section 12 includes a plurality of intake ports 1221 and a plurality of exhaust ports, all of which are provided on the first back panel section 1401, and at least some of the exhaust ports are provided on the first back panel section 1401.

[0396] Alternatively, when the casing blowing section 1201 is in the first distribution form, all of the multiple blowing ports are installed on the first back plate section 1401. When the casing blowing section 1201 is in the second or third distribution form, some of the multiple blowing ports are installed on the first back plate section 1401, and the other some are installed on the two first side plate sections 1501; that is, the first blowing section 1211 is installed on the first back plate section 1401, and the second blowing section 1212 is installed on at least one of the first side plate sections 1501.

[0397] In one embodiment, along the longitudinal direction of the casing assembly 100, the casing assembly 100 further includes a second case segment 40 connected to the first case segment 30, the first case segment 30 being located on a side of the second case segment 40 closer to the front end of the casing assembly 100.

[0405] Specifically, the portion of panel 21 in fourth case portion 42 is a second panel portion 212, and panel 21 includes a first panel portion 211 and a second panel portion 212 that are connected to each other.

[0406] Specifically, the fourth case portion 42 further includes two fourth side plate portions 222, each of which is connected to one of the two long sides of the second panel portion 212, and each of which is removably connected to the first casing 10.

[0407] Specifically, the two fourth side plate portions 222 and the two second side plates 22 are installed in a one-to-one correspondence, and the portion of each second side plate 22 in the fourth case portion 42 is the corresponding fourth side plate portion 222.

[0408] Generally, to the left of the dashed lines in FIGS. 47 and 48 is the second case segment 40 and to the right of the dashed lines is the first case segment 30.

[0409] In one embodiment, the second casing 20 is a unitary molded structure and the first casing 10 is a unitary molded structure.

[0410] In one embodiment, each of the first side plate portions 1501 has a first end connected to the first back plate portion 1401 and a second end connected to the second casing 20, and in the direction from the first end to the second end of each of the first side plate portions 1501, each of the first side plate portions 1501 gradually moves away from the other first side plate portion 1501, that is, in the direction from the first end to the second end of each of the first side plate portions 1501, each of the first side plate portions 1501 gradually expands in a direction away from the internal chamber of the casing assembly 100. In this way, the entire skin treatment device can blow out toward the back side, which is advantageous in increasing the blowing area.

[0411] In one embodiment, each third side panel portion 221 has a first end connected to the first panel portion 211 and a second end connected to the first casing 10, and in the direction from the first end to the second end of each third side panel portion 221, each third side panel portion 221 gradually moves away from the other third side panel portion 221, i.e., in the direction from the first end to the second end of each third side panel portion 221, each third side panel portion 221 gradually widens in a direction away from the internal chamber of the casing assembly 100, and thus can fit into the first casing 10.

[0412] In one embodiment, each first side panel 15 has a first end connected to the back panel 14 and a second end connected to the second casing 20, and in a direction from the first end to the second end of each first side panel 15, each first side panel 15 gradually moves away from the other first side panel 15 such that the first side panel 15 diverges in a direction away from the other first side panel 15. In a direction from the rear end to the front end of the casing assembly 100, the degree of divergence of each first side panel 15 gradually increases at the gripping regions 16 and the raised portions 13, i.e., the divergence angle of each first side panel 15 gradually increases.

[0413] As can be seen from the above design, the degree of expansion at the raised portion 13 of the first side panel 15 is relatively large, and thus the width at the raised portion 13 of the first side panel 15 can be made relatively large, and further the plate surface at the raised portion 13 of the first side panel 15 can be made relatively large, which makes it easier to make the installation area of ​​the second blowing area relatively large, i.e., makes it easier to arrange a relatively large number of second blowing outlets 1214.

[0414] Specifically, the width direction of the first side plate 15 is perpendicular to the longitudinal direction of the casing assembly 100 .

[0415] Furthermore, the degree of expansion in the gripping area 16 of the first side panel 15 is relatively small compared to the degree of expansion in the raised portion 13 of the first side panel 15, and thus, it is advantageous that the ribs at the connection points between the first side panel and the second casing in the gripping area 16 are not noticeable, which is advantageous for improving comfort when gripping.

[0416] In one embodiment, each second side panel 22 has a first end connected to the panel 21 and a second end connected to the first casing 10, and in a direction from the first end to the second end of each second side panel 22, each second side panel 22 gradually separates from the other second side panel 22 such that it flares in a direction away from the other second side panel 22. In a direction from the rear end to the front end of the casing assembly 100, the degree of flaring of each second side panel 22 gradually decreases at the gripping regions 16 and the ridges 13.

[0418] Specifically, as shown in FIG. 55, a locking hole 1801 is opened in the side wall of the insertion groove 18, and a locking table 231 is protruded from the side wall of the insertion portion 23. When the insertion groove 18 is inserted into the insertion groove 18, the locking table 231 is locked in the locking hole 1801, thereby ensuring a stable connection effect between the first casing 10 and the second casing 20.

[0419] Alternatively, the number of the insertion parts 23 and the number of the insertion grooves 18 may be multiple, and the multiple insertion parts 23 may be inserted into the multiple insertion grooves 18 in a one-to-one correspondence.

[0420] Specifically, at least one insertion portion 23 is provided on each second side plate 22 and / or at least one insertion groove 18 is provided on each second side plate 22 .

[0421] Specifically, at least one insertion portion 23 is provided on each first side plate portion 1501, and / or at least one insertion groove 18 is provided on each first side plate portion 1501.

[0422] 56, the panel 21 includes two panel portions 210 that are connected to each other, and the long sides of the two panel portions 210 are connected. Each panel portion 210 has a first end that is connected to the other panel portion 210 and a second end that is away from the other panel portion 210. In the direction from the second end to the first end of each panel portion 210, the panel portion 210 gradually moves away from the back panel 14.

[0423] Specifically, the distribution direction of the two panel portions 210 is perpendicular to the longitudinal direction of the casing assembly 100, and the distribution direction of the two panel portions 210 is perpendicular to the distribution direction of the panel 21 and the back plate 14.

[0424] Specifically, the panel 21 is an arc-shaped plate that protrudes in a direction away from the back panel 14 .

[0425] 57, the skin treatment device further includes a fan 500, which has an intake port and is installed in the casing assembly 100, and the intake port of the fan 500 is installed corresponding to the gripping region 16. By installing the fan 500 in the gripping region 16 in this manner, the fan 500 and the suction portion 1202 can be installed adjacent to each other, thereby making it possible to easily suck in external gas.

[0426] Of course, in other embodiments, the suction portion 1202 may be located on the side of the gripping area 16 closer to the rear end of the casing assembly 100, i.e., the casing outlet portion 1201 and the suction portion 1202 may be provided on both the front and rear sides of the gripping area 16, respectively.

[0427] Furthermore, the portion of the casing blowing section 1201 that is installed on the back panel 14 is a designated blowing section 1215, and the designated blowing section 1215 is located on the side of the suction section 1202 that is away from the gripping area 16, and the skin treatment device further includes a fan 500 having an inlet and an exhaust port, and the internal chamber of the casing assembly 100 includes a first region 51 and a second region 52, and the designated blowing section 1215 and the suction section 1202 are both installed corresponding to the first region 51, and the second region 52 is installed corresponding to the gripping area 16, and at least a portion of the fan 500 is installed within the second region 52, and the inlet of the fan 500 is located in the second region 52, and the inlet of the fan 500 is installed toward the gripping area 16, and the exhaust port of the fan 500 is installed toward the first region 51. In this way, the structural distribution within the casing assembly 100 can be made relatively rational.

[0428] Generally, the area below the dashed line in FIG. 58 is a first region 51 and the area above the dashed line is a second region 52.

[0429] Optionally, a portion of the fan 500 is located in the second region 52 and another portion of the fan 500 is located in the first region 51 .

[0430] 57 and 58, an intake port 301 is an intake port for a fan 500, and an exhaust port 302 is an exhaust port for the fan 500. In FIG.

[0431] In one embodiment, as shown in Figures 57 and 58, the skin treatment device further includes a partition section 940, which is installed in the first area 51 and is located at the boundary between a specified blowing section 1215 and an intake section 1202, thereby directing the airflow flowing in from the intake section 1202 to the second area 52, and further directing the airflow into the fan 500 through the intake port of the fan 500.

[0432] Specifically, the partition portion 940 and the back panel 14 are installed at a preset angle, the preset angle has a value range of 80 degrees to 100 degrees, and the preset angle is installed toward the second area 52.

[0433] Specifically, the partition 940 has a plate-like structure.

[0434] Specifically, as shown in FIG. 58, the partition portion 940 is installed on the heat dissipation bracket 402.

[0435] 57 and 58, the skin treatment device further includes a guide portion 950, which is connected to the partition portion 940 and is located on the side of the partition portion 940 facing the second region 52, thereby guiding the airflow flowing in from the suction portion 1202 to the second region 52 by the guide portion 950. The arrows in Figs. 57 and 58 indicate that the airflow flowing in from the suction portion 1202 is guided to the second region 52 by the action of the partition portion 940 and the guide portion 950, and then flows into the fan 500 through the air intake of the fan 500.

[0436] Specifically, the surface of guide portion 950 facing back panel 14 is guide surface 951, which has a connection end connected to partition portion 940 and a free end moving away from partition portion 940, and guide surface 951 gradually moves away from back panel 14 in the direction from the connection end of guide surface 951 to the free end.

[0437] Specifically, the partition portion 940 has a first end connected to the back panel 14 and a second end away from the back panel 14, and the connection end of the guide surface 951 is located between the first end and the second end of the partition portion 940.

[0438] The space between guide surface 951 and back plate 14 and located toward second region 52 of partition section 940 is suction space 952. By setting the preset angle range to 80 degrees to 100 degrees, positioning the connecting end of guide surface 951 between the first end and the second end of partition section 940, and gradually separating guide surface 951 from back plate 14 in the direction from the connecting end of guide surface 951 to the free end, suction space 952 can be made relatively large, which is advantageous for increasing the suction flow rate.

[0439] Specifically, in the direction from the first region 51 to the second region 52, the free end of the guide surface 951 extends to the fan 500, and in this way, all of the airflow flowing in through the suction portion 1202 can be guided to the fan 500, and a relatively large amount of suction airflow can be ensured to flow into the fan 500.

[0440] Specifically, the guide portion 950 has a plate-like structure, and the plate surface of the guide portion 950 facing the back plate 14 is a guide surface 951.

[0441] As can be seen from the above description, the above embodiments of the present application can achieve the following technical effects.

[0442] The heat generated by the cold pack assembly is thermally conducted by the thermal conductive structure through the first thermal conductive part, and is transferred to the second thermal conductive part, and is dissipated by the heat dissipation fin assembly thermally connected to the second thermal conductive part. In the present application, the second thermal conductive part thermally connected to the heat dissipation fin assembly is installed corresponding to the light emitting assembly, so that the distance between the heat dissipation fin assembly and the cold pack assembly can be made closer, thereby shortening the heat conduction path. That is, the heat dissipation fin assembly and the light emitting assembly are stacked (installed in layers) in the thickness direction of the casing assembly, and compared with the cold pack assembly, the light emitting assembly, and the heat dissipation fin assembly being arranged in a "straight line" in the prior art, the skin treatment device in the present application can shorten the overall length of the heat conductive structure, shorten the heat conduction path, and shorten the distance between the heat dissipation fin assembly and the light emitting assembly, thereby improving the heat dissipation efficiency, and solving the problem in the prior art that the heat conduction member of the skin treatment device is relatively long, which affects the heat dissipation efficiency of the heat dissipation fin assembly.
