[0059] As Figures 1-12 Embodiments of the present application provide some embodiments of handheld cosmetic devices and cosmetic systems with improved features for improving the user experience associated with the use of handheld cosmetic devices and cosmetic systems. Although embodiments of the present application can be applicable to a wide range of handheld cosmetic devices, some embodiments of the present disclosure are particularly suitable for household personal cosmetic devices, as described in more detail below.

[0060] For example, in some embodiments, the handheld cosmetic device is provided with multiple air channels. Heat can be removed in only one direction in the device, and the heat dissipation path is the shortest, while effectively separating each different heat source point inside the device, so that each heat source has a relatively independent air flow pipe. In another embodiment, the circuit board 200 in one of the air channels has an opening 210 for light to pass through and illuminate out, and a bearing area 240 is formed on the adjacent side of the width direction of the opening 210, which is used to load the instantaneous current of the light source 220 and the heat generated with the instantaneous current. Through the optimized layout of the multiple air channels and the improvement of the related components, better heat balance is achieved inside the device, providing a good user experience for the user.

[0061] In another embodiment, the interior of the device is further provided with some thermal insulation, which is arranged between the air ducts, and is operable to isolate the heat between the air ducts, or further reduce the impact of the heat on other components in the interior of the device. In some embodiments, the thermal insulation can be used to reduce the heat transfer of the VC heat plate 510 to prevent the heat transfer failure of the VC heat plate 510 itself. Of course, in other embodiments, the thermal insulation is also arranged on the inner wall of the light-transmitting crystal 700 and a part of the shell 100 to block the heat transfer of the heat radiation in the interior space of the device to these components.

[0062] In another embodiment, the handheld cosmetic device can be used in communication connection with a mobile terminal.

[0063] In another embodiment, the capacitor can be externally arranged on the handheld cosmetic device and provide power to it, which can provide a more miniaturized design and provide a better user experience.

[0064] In order to better understand the features and aspects of the handheld cosmetic device with multiple air ducts and the cosmetic system provided according to the present application, the following sections provide further context of the present disclosure by discussing several specific implementations of the multiple air ducts and the handheld cosmetic device with multiple air ducts according to the embodiments provided according to the present application. The specific embodiments discussed are merely for exemplary purposes, and other embodiments can be employed in other handheld cosmetic devices and cosmetic systems.

[0065] As used herein, the term "handheld cosmetic device" includes any handheld cosmetic device designed to provide light therapy to a user's skin. An epilator is one type of handheld cosmetic device, and a light therapy skin rejuvenation device is another type of handheld cosmetic device.

[0066] Figure 1 A schematic diagram of the shell 100 of the handheld cosmetic device with multiple air ducts according to some embodiments of the present disclosure is depicted, Figure 2 A schematic diagram of the shell 100 of the handheld cosmetic device with multiple air ducts according to some embodiments of the present disclosure is depicted, Figure 1 The exploded schematic diagram of the shell of the handheld cosmetic device with multiple air ducts is shown. As Figures 1-2As shown, the housing 100 includes an upper shell 110 and a lower shell 120 that is assembled with the upper shell 110, and has an exhaust panel assembled at the front end thereof, and has exhaust ports 130 arranged in an array. In some embodiments, the air inlet 111 is arranged at the middle of the upper shell 110, so that the air inlet 111 and the exhaust ports 130 are in different air directions. The housing 100 has a generally cylindrical extension, and forms a generally cylindrical cavity in the upper shell 110 and the lower shell 120, and has a larger cavity area at one end thereof near the exhaust ports 130 than other areas, and has a cavity area one 112 at the front end of the upper shell 110 and a cavity area two 121 at the front end of the lower shell 120, which enclose the cavity area for accommodating the main components in the handheld cosmetic device with multiple air channels, and has a light outlet (not shown in the figure) arranged below the cavity area two 121. The air inlet 111 is designed to have a better anti-interference effect when being held, and is not easily blocked by the user's hand; and the exhaust ports 130 are arranged in the extension direction of the length of the housing 100, and the air flow direction of the exhaust ports 130 is not easy to point to the user's skin when being held, which can bring a better user experience. The embodiments of the present disclosure are not limited to the specific shape, structure or cavity area with different positions of the housing 100, and in other embodiments, the cavity area one 112 and the cavity area two 121 can have different shapes to adapt to different types of internal main components, such as air channels, light sources, etc. of different structures, and the cavity area can be a single cavity or more than two cavities.

[0067] Figure 3 is an internal component explosion diagram of a handheld cosmetic device with multiple air channels according to an embodiment of the present disclosure, Figure 4 depicts Figure 3 is a cross-sectional view of a part of the handheld cosmetic device with multiple air channels in the length direction thereof, Figure 5 depicts Figure 3 is a cross-sectional view of the handheld cosmetic device with multiple air channels in the width direction thereof. As Figures 3-5 As shown, the handheld cosmetic device with multiple air channels can include a circuit board 200, a flow guide cover 300, a fan 400, a heat dissipation assembly 500, a cover shell 600, a light-transmitting crystal 700, a semiconductor refrigeration sheet 800, and a heat insulation member.

[0068] The circuit board 200 has an opening 210 arranged directly below the light source 220, and can further include a conductive support 250 for electrically connecting both ends of the light source 220. In some embodiments, the circuit board 200 is arranged along the extension direction of the generally cylindrical cavity of the housing 100, and is arranged in the cavity area one 112 and the cavity area two 121. Figure 2The cavity region one 112 and the rear end of the cavity region two 121 are equipped with capacitors to provide power to the circuit board 200, and the capacitors can be a single capacitor or two or more capacitors. In another embodiment, the opening 210 of the circuit board 200 is rectangular, as shown in Figure 6 , and the light source 220 can be a long strip-shaped gas excitation light source such as a xenon lamp; the xenon lamp and the opening 210 are arranged along the length direction of the circuit board 200, and the length of the xenon lamp can be greater than or equal to the length of the opening 210, and the width is less than the width of the opening 210. In some embodiments, the opening 210 can have different shapes to accommodate different types of light sources 220 so that the light can be optimally transmitted outward through it, such as an oval or a circle, etc.

[0069] In the embodiment where the opening 210 is rectangular and the light source 220 is a xenon lamp, the two ends of the xenon lamp are electrically connected to the circuit board 200 through the conductive support 250, which is powered by the capacitor. As some embodiments, in the working state, the capacitor provides a large current of 150A to the xenon lamp, and the instantaneous current can cause the circuit board 200 to generate a certain amount of high heat in the area located on one side of the opening 210. This is because after the opening 210 is set, the area of the circuit board 200 between the two ends of the xenon lamp connected to the power supply is greatly reduced, which results in that the effective load area is not enough to bear the above-mentioned current, thereby causing the area to overheat.

[0070] Figure 7 is Figure 4 The partial cross-sectional view of the circuit board 200 under the fairing 300. In some embodiments, the area of the circuit board 200 used to load a large current of the light source 220 is defined as the bearing area 240, which is located on one side of the opening 210. In one embodiment, the bearing area 240 has a length and a width calculated by the current load to meet the upper limit of the bearing area 240 that can bear the maximum current when the light source 220 is excited, which also means that the bearing area 240 as the effective load area, its area needs to be reasonably calculated. As Figure 6 , along the width direction of the circuit board 200, at least part of the bearing area 240 is formed between the inner edge 241 of the opening 2101 and the outer edge 242 of the circuit board 200.

[0071] Figure 8 depicts a perspective structural view of the fairing 300 for the light source 220 and the bearing area 240 according to some embodiments of the present disclosure. Figure 9 depicts Figure 8 another perspective structural view of the fairing 300. As Figures 8-9As shown, the air deflector 300 defines at least a portion of a first airflow duct 01 and at least a portion of a second airflow duct 02 via a first inner wall 310 and a second inner wall 320 located on one side of it, respectively. The light source 220 is arranged within the first airflow duct 01, while the supporting area 240 is arranged within the second airflow duct 02. The airflow allows for the removal of heat from the light source 220 and the supporting area 240, respectively. In some embodiments, the first airflow duct 01 and the second airflow duct 02 are arranged side-by-side. In embodiments where the light source 220 is a xenon lamp, the arrangement direction of the first inner wall 310 in the air deflector 300 is consistent with the length direction of the xenon lamp, and the supporting area 240 is located adjacent to the opening 210 and accommodated by the second airflow duct 02. The first airflow duct 01 may be provided with... Figure 3 The reflector 221 shown is positioned above the xenon lamp and housed by the first airflow duct 01. During operation, a portion of the light energy instantaneously released by the xenon lamp is focused and reflected to the light outlet by the reflector 221. The first inner wall 310 and the second inner wall 320 are adjacent to each other and separated by, for example, an injection-molded part. The size and shape of the first inner wall 310 and the second inner wall 320 can be designed to match the size and shape of their respective light source 220 and supporting area 240. The first airflow duct 01 defined by the first inner wall 310 can be a generally U-shaped cylindrical cavity, and the first airflow duct 01 defined by the second inner wall 320 can also be a generally cylindrical cavity. Both the first airflow duct 01 and the second airflow duct 02 extend in the same direction, and both can be open along their extension paths. The embodiments disclosed herein are not limited to any particular shape or structure of the first airflow duct 01 and the second airflow duct 02. For example, the first airflow duct 01 may be designed as a flared shape that gradually expands outward from the inside to obtain a larger airflow.

[0072] The air deflector 300 also includes a guide member 350 located at its front end. In some embodiments, the guide member 350 is integrally designed with the air deflector 300, located on the centerline of the first airflow duct 01 and symmetrically constructed. When airflow is discharged outward through the first airflow duct 01, it passes through the guide member 350 on its centerline, thereby guiding the airflow along a predetermined path. In some embodiments, the guide member 350 has a first surface section and a second surface section extending from each other on the side facing the inlet end of the first airflow duct 01. Figure 9 (Not shown in the image), after passing through the guide element 350, the airflow will be guided to two different outlet directions through the first surface section and the second surface section respectively. Figure 9In some embodiments, the flow guide 350 is configured as a substantially V-shaped structure with a curved surface, and the extending areas of the first surface section and the second surface section have a curved surface with a circular arc transition section. In some embodiments, the flow guide 300 further has an outwardly expanding structure defined by the flow guide surface 330 at the outlet, and the first surface section and the second surface section are configured with the air outlets 302 in different directions with respect to the flow guide surface 330. The flow guide 350 not only guides the air flow in different directions, but also effectively blocks most of the light emitted by the light source 220 as a light shielding member, thereby avoiding the safety problem of strong light entering the eyes of the user. In some embodiments, the flow guide 350 can also have different shapes to adapt to the flow direction of the air flow in the first air flow pipe 01 and the shape of the flow guide surface 330 to provide the best shape for air outlet and light shielding. For example, the flow guide 350 can also be a separate member designed separately from the flow guide 300 and arranged horizontally along the width direction of the flow guide 300.

[0073] In embodiments where the flow guide 350 and the flow guide 300 are designed as one body, the flow guide 300 further has air flow openings 340. The air flow openings 340 are arranged on the wall extending from the first inner wall 310 and the second inner wall 320 to the position of the flow guide 350 to achieve the first air flow pipe 01 having multiple air outlets at the end for air flow to pass through, so as to provide better air exhaust efficiency. In some embodiments, the air flow openings 340 can be configured as the opening shape shown in Figure 8 and Figure 9 When the air flow reaches the flow guide 350, the air pressure in this area increases due to the obstruction, so the air flow flows from high pressure to low pressure, and the hot air flow is discharged through the air flow openings 340 and the air outlets 302 on both sides of the flow guide 350, while the flow guide 350 can block most of the light emitted by the light source 220.

[0074] In some embodiments, the flow guide 300 further has other air flow pipes above the outer wall 360, such as Figure 4 and Figure 5As shown, the heat dissipation member 530 is arranged above the outer wall 360, and the heat dissipation member 530 is arranged in the third air flow duct 03, and the first air flow duct 01 and the third air flow duct 03 are arranged in an up-down manner and discharge air flow in the same direction. In the embodiment in which the flow guide member 350 and the flow guide cover 300 are integrally designed, the flow guide member 350 is located at the end of the first air flow duct 01, and the air flow port 340 is located above the surface section on the inner side of the flow guide member 350, and the air flow port 340 communicates the first air flow duct 01 and the third air flow duct 03, and when the air flow reaches the flow guide member 350, the air flow is driven to pass through the air flow port 340 into the third air flow duct 03 due to the resistance, and finally is discharged together with the air flow in the third air flow duct 03.

[0075] The lower edge of the flow guide member 350 can have a gap 370 with the circuit board 200. In some embodiments, the flow guide member 350 is integrally formed with the flow guide cover 300, the flow guide cover 300 is installed above the circuit board 200, and the lower edge of the flow guide member 350 is raised to form the gap 370 for a part of the air flow in the first air flow duct 01 to be discharged through the gap 370. More specifically, in some embodiments, the gap 370 provides another air outlet for the air flow in the first air flow duct 01 to be directly discharged, which can facilitate the air flow to be discharged more smoothly. In the embodiment in which the light source 220 is a xenon lamp, the xenon lamp is arranged in the first air flow duct 01 along the extension direction thereof, the xenon lamp is parallel to the circuit board 200, and the xenon lamp is arranged above the opening 210 with a certain assembly gap, as shown in Figure 4 As shown, the reserved height of the gap 370 is similar to or substantially equal to the height of the xenon lamp from the opening 210, which can facilitate the hot air flow below the xenon lamp to be quickly discharged through the gap 370, and the heat at other positions can be discharged through the air outlets 302 on both sides of the flow guide member 350, or in some embodiments, can be discharged through the air flow port 340 into other air flow ducts.

[0076] Now referring to Figure 4 , a cross-sectional schematic view of a part of the handheld cosmetic device with multiple air ducts in the length direction thereof is shown. As shown in Figure 4As shown, the circuit board 200 is provided with an opening 210, and at the front and back ends of the opening 210 in the length direction of the circuit board 200, gaskets 231 for assembling the filter 230 are arranged. The gaskets 231 provide assembly positions for the filter 230, so as to ensure that the filter 230 can be assembled in the opening 210 and kept substantially in the same horizontal plane as the circuit board 200. In some embodiments, the gaskets 231 can be high-temperature-resistant rubber products, which are assembled with the support 710 after clamping the filter 230, so that the filter 230 has assembly with respect to the support 710. The light-transmitting crystal 700 can be installed in the support 710 to transmit light, and the support 710 provides support for the gaskets 231 and keeps the filter 230 in a plane parallel to the light-incident surface 702. In some embodiments, the gaskets 231 can be made of silicone rubber.

[0077] Figures 4-5 Embodiments of multiple air flow channels inside a handheld cosmetic device with multiple air ducts are shown. Although Figures 4-5 The air flow channels shown in the figures have relatively fixed arrangement positions and shapes, but it should be understood that embodiments of the present disclosure are not limited to specific shapes, configurations or differential positions of the various air flow channels.

[0078] In some embodiments, the first air flow channel 01, the second air flow channel 02, the third air flow channel 03 and the fourth air flow channel 04 are arranged side by side and independently. The light source 220 can be arranged in the first air flow channel 01, the carrying area 240 can be arranged in the second air flow channel 02, the heat dissipation member 530 can be arranged in the third air flow channel 03, and the heat conduction member can be arranged in the fourth air flow channel 04. Figure 5The cross-sectional view of the handheld cosmetic device with multiple air ducts in the width direction is shown, and the specific position relationship of each air flow pipe is fully displayed. In the embodiment where the flow guide cover 300 is arranged above the circuit board 200, the heat conducting member can include a VC heat plate 510, one end of which is located below the circuit board 200 and connected with the light-transmitting crystal 700 through the semiconductor refrigeration sheet 800, and the other end is located above the circuit board 200 and connected with the heat dissipation member 530, thereby forming a heat dissipation assembly 500 on the refrigeration link of the light-transmitting crystal 700. In this embodiment, the VC heat plate 510 separates the air flow pipe into the fourth air flow pipe 04 and the first air flow pipe 01, the second air flow pipe 02 and the third air flow pipe 03 located on the left and right sides of the VC heat plate 510, and the flow guide cover 300 separates the first air flow pipe 01, the second air flow pipe 02 and the third air flow pipe 03 into upper and lower layouts, thereby forming a four-channel heat isolation structure, so that each heat source point can be independently ventilated and cooled, and a better heat balance effect is achieved in the device. In some embodiments, the air flow port 340 can be provided on the outer wall 360 of the flow guide cover 300 to connect the end of the first air flow pipe 01 with the end of the third air flow pipe 03.

[0079] In the embodiment where the four air flow pipes are arranged in parallel and independently, a cover 600 is also provided, which is arranged above the circuit board 200 and contains the heat dissipation member 530, the light source 220 and at least part of the heat conducting member. The top end of the heat conducting member abuts against the inner wall 601 of the cover 600, and the fourth air flow pipe 04 is defined by at least part of the inner wall 601 and at least part of the circuit board 200. Figure 5 As shown in the embodiment, the cover 600 and the upper surface of the circuit board 200 cover the four air flow pipes and separate most of the heat sources into four independent channels, for example, the second inner wall 320, the bearing area 240 and at least part of the inner wall 601 of the cover 600 together define the second air flow pipe 02. This embodiment is beneficial for rapid assembly to form four air flow pipes, and has lower requirements for assembly precision. In some embodiments, the heat dissipation member 530 can be connected to the outer wall 360 of the flow guide cover 300 and then retained on the circuit board 200 by the cover 600 to meet the assembly requirements after being stressed, and the connection methods include but are not limited to clamping, screw fastening, etc.

[0080] In some embodiments, the heat conducting member comprises the VC vapor chamber 510, and can further comprise the rigid attachment member 520. The VC vapor chamber 510 has a dense capillary structure by itself, and the end connected to the semiconductor refrigeration sheet 800 needs to be fastened and attached by force. Local pressure force can cause unexpected deformation of the capillary structure. Therefore, the rigid attachment member 520 with a similar profile is installed on the outer wall of the VC vapor chamber 510 to improve the force balance, thereby avoiding damage to the capillary structure caused by local fastening force, and further avoiding the failure of heat conduction.

[0081] In some embodiments, the rigid attachment member 520 can be a copper plate with good thermal conductivity, which has a certain rigidity, and copper can be used as a good heat conduction carrier to transfer heat. Figure 5 In some embodiments, the rigid attachment member 520 is attached to the VC vapor chamber 510, and the combination constitutes a heat conducting member. One end of the VC vapor chamber 510 is attached to the semiconductor refrigeration sheet 800 to conduct heat to the heat sink 530, and the other part of the heat is transferred to the fourth air flow pipeline 04 through the copper rigid attachment member 520. The fan 400 provides air flow to discharge the heat.

[0082] In the embodiment in which the four air flow pipelines are arranged in parallel and independently, the air flow inlet ends of the cover 600 and the flow guide cover 300 are arranged on the same vertical plane, as shown in Figure 4 The port 410 of the fan 400 is attached to the air flow inlet ends of the cover 600 and the flow guide cover 300. The air flow provided by the air flow outlet 411 of the fan 400 can be guided by the direction of the shell member of the cover 600 and the flow guide cover 300 to introduce the air flow into the four air flow pipelines synchronously. In another embodiment, the air inlet 111 is arranged directly above the fan 400, so that the air flow entering the fan 400 is vertically downward, and the air flow blown out of the fan 400 is horizontally outward, achieving the shortest air flow path in the handheld beauty device with multiple air ducts, which is beneficial to rapid heat dissipation.

[0083] As defined herein, the use of multiple air flow pipelines can independently dissipate heat from multiple different heat sources, which is beneficial to the heat balance of the internal air duct; that is, different heat source points have a large heat difference. Once the heat is transferred in the form of heat radiation or other forms through structural members or assembly gaps, it will inevitably have a certain negative impact on the internal components of the handheld beauty device with multiple air ducts, and even cause the device to malfunction. In various embodiments, the different air flow pipelines can be further insulated by a heat insulating member to further eliminate the negative effects caused by heat transfer.

[0084] Reference is now made to Figure 3 , Figure 4 , Figure 5 and Figure 7 .Figure 3 、 Figure 4 、 Figure 5 and Figure 7 all show the heat insulation piece configuration inside the handheld cosmetic device with multiple air ducts on multiple heat transfer paths. Different problems caused by heat transfer in different areas are solved by the heat insulation piece layout in different positions.

[0085] In an embodiment, the heat dissipation piece 530 is arranged above the flow guide cover 300, and the heat conduction piece connected with the heat dissipation piece 530 is arranged on one side of the flow guide cover 300. In the embodiment in which the heat conduction piece includes the VC vapor chamber 510, the VC vapor chamber 510 has a dense capillary structure inside to transfer the heat of the semiconductor refrigeration sheet 800, and the transfer path passes through the flow guide cover 300. However, in some embodiments, the light source 220 can use a gas excitation light source such as a xenon lamp, and the instantaneous energy release of the gas excitation light source can cause it to gather hundreds of degrees Celsius of high temperature in the first air flow pipe 01. In the heat transfer path, part of the high heat will be transferred to the VC vapor chamber 510 on one side through the flow guide cover 300. Since this part of the high heat is heat conduction in the middle of the transfer path of the heat conduction piece, according to the heat conduction principle of the VC vapor chamber 510, the capillary structure will transport the high heat to the low heat area. However, the high heat of the light source 220 will be obviously higher than the heat transfer heat of the semiconductor refrigeration sheet 800, which will cause the heat conduction of the light source 220 to be transported in the direction of the semiconductor refrigeration sheet 800 in reverse, resulting in the failure of the refrigeration system. This means that the light source 220 and the VC vapor chamber 510 need to be well thermally insulated. In an embodiment, as shown in Figure 4 , a first heat insulation piece 910 is arranged on the outer wall 360 of the flow guide cover 300, the first heat insulation piece 910 extends from a first end 911 of the edge of the heat dissipation piece 530 and is folded to a second end 912 of the lower edge of the flow guide cover 300, thereby blocking the heat of the light source 220 from being transferred to the VC vapor chamber 510, and also blocking the heat from being transferred to the heat dissipation piece 530. In some embodiments, the first heat insulation piece 910 can be aerogel, which can be used as a lighter and more excellent heat insulation material.

[0086] In the embodiment in which the heat transfer is blocked by the first heat insulation piece 910, a second heat insulation piece 920 can be further arranged on the back of the reflector cup 221 to reduce the heat transfer of the heat in the first air flow pipe 01 to the side of the outer wall 360. In some embodiments, the second heat insulation piece 920 can be aerogel, which can be used as a lighter and more excellent heat insulation material.

[0087] Similar to the first thermal insulation 910 and the second thermal insulation 920, the light-transmitting crystal 700 needs to be cooled by the semiconductor refrigeration sheet 800 because it needs to receive the light irradiation of the light source 220 and irradiate the light out of the light-emitting surface 701. Since the light-transmitting crystal 700 is generally a multi-faceted block structure, most of the surfaces except the light-incident surface 702 and the surface in contact with the semiconductor refrigeration sheet 800 will receive heat from the inside of the device through heat conduction. On the one hand, the semiconductor refrigeration sheet 800 cools the light-transmitting crystal 700, and on the other hand, heat is conducted to the light-transmitting crystal 700, which will inevitably reduce the cooling efficiency and effect of the light-transmitting crystal 700. As shown in FIGS. Figure 5 and Figure 3 In an embodiment, the circuit board 200 has a light-transmitting opening 210, and the filter 230 is installed in the opening 210. The light emitted by the light source 220 passes through the filter 230 and irradiates the light-incident surface 702 of the light-transmitting crystal 700 and irradiates out of the light-emitting surface 701. The working temperature of the circuit board 200 will cause a part of the heat to be gathered in the cavity area two 121, and the light-transmitting crystal 700 can be fixed and supported by the support 710, which causes a part of the heat to be transferred to the light-transmitting crystal 700 through the support 710. The other crystal surfaces of the light-transmitting crystal 700 except the light-emitting surface 701, the light-incident surface 702, and the surface in contact with the semiconductor refrigeration sheet 800 are provided with thermal insulation, thereby preventing heat transfer to the light-transmitting crystal 700. In some embodiments, the light-transmitting crystal 700 is a hexahedral rectangular structure, and the other crystal surfaces can include three side surfaces as shown in FIG. Figure 12 The corresponding thermal insulation includes the third thermal insulation 931, the fourth thermal insulation 932, and the fifth thermal insulation 933. The other crystal surfaces are covered by the multiple thermal insulations to achieve thermal isolation. Embodiments of the present disclosure are not limited to the configuration of the light-transmitting crystal 700, nor to the arrangement form and number of the thermal insulations, and in other embodiments, the multiple thermal insulations can be used as a whole thermal insulation with continuity, and the purpose is to maximize the effective thermal insulation coverage area to isolate heat transfer. In some embodiments, the third thermal insulation 931, the fourth thermal insulation 932, and the fifth thermal insulation 933 can be aerogel.

[0088] In some embodiments, the sixth thermal insulation 940 can be arranged on the inner wall of the shell of the cavity area two 121 based on the modeling structure of the wall. In some embodiments, the installation position of the circuit board 200 and the semiconductor refrigeration sheet 800 is located in the cavity area two 121, which generates heat in the working state. The arrangement of the sixth thermal insulation 940 can reduce the transfer of this part of heat to the lower shell 120, thereby improving the user experience. In some embodiments, the sixth thermal insulation 940 can be aerogel.

[0089] ​A wireless paired beauty system is shown, the beauty system comprising a mobile terminal (e.g., a computer, a smart phone, a tablet, a smart watch, etc.) and a handheld beauty device with multiple air channels, the mobile terminal being wirelessly pairable with the handheld beauty device with multiple air channels; in an embodiment, the pairing can be initiated by the handheld beauty device with multiple air channels, the mobile terminal can be instructed to pair with the handheld beauty device with multiple air channels in response to a user's input. In other embodiments, the handheld beauty device with multiple air channels can comprise a wireless transceiver module that will receive and send instructions. Upon receiving the pairing instruction, the handheld beauty device with multiple air channels can pair with the mobile terminal via a wireless communication protocol that supports bidirectional data transmission (e.g., Bluetooth).

[0090] In some embodiments, the capacitor that provides power to the handheld beauty device with multiple air channels is an external capacitor (not shown), which can be plugged into a power connection port of the handheld beauty device with multiple air channels via a cable. The external capacitor not only can greatly reduce the size of the handheld beauty device with multiple air channels, but also means that a larger capacitor can provide more persistent and continuous power to the light source 220, and also provides a higher possibility for a variety of light energy release forms. For example, a dual-capacitor structure can cooperate with two xenon lamps to alternately achieve light output, reducing the interval time and improving the intensity of energy release.
