Description

Technical Field

[0001] This utility model relates to the field of beauty equipment technology, and in particular to a portable beauty device. Background Technology

[0002] Beauty devices can be categorized by function, including whitening, skin rejuvenation, wrinkle removal, and hair removal. The most common type uses light of a specific wavelength to achieve these different functions. As user needs continue to change, these beauty devices are gradually shifting from large instruments to miniaturized personal care devices.

[0003] Because these personal beauty devices require the integration of a large number of components inside, and some of these components often generate different high temperatures during operation, these high temperatures need to be quickly exhausted to the outside of the device through a reasonable airflow design, thereby ensuring normal use of the device and a good user experience.

[0004] In existing technologies, heat-conducting components are used inside the equipment to transfer and dissipate the heat from the cooling components. Part of this heat is conducted to the heat sink, while the other part diffuses into the equipment through the heat radiation of the heat-conducting components themselves. Existing designs often only consider the heat conducted to the heat sink, while ignoring the problem of the heat continuously accumulated by the heat radiation of the heat-conducting components themselves.

[0026] This utility model embodiment provides a portable beauty device, such as... Figures 1-4 As shown, the portable beauty device includes a housing 1, with an exhaust vent 11 at the front end. Inside the housing 1 are a light source 2, a cooling component 3, a light-transmitting crystal 4, and a heat-conducting component 5. The light source 2 provides the light energy required for beauty treatments; the light emitted by the light source 2 is emitted after passing through the light-transmitting crystal 4. The cooling component 3 has a cold source surface and a corresponding heat source surface. The light-transmitting crystal 4 has a contact surface that is thermally connected to the cold source surface, and the cold source surface conducts refrigerant through the contact surface to the light-transmitting crystal 4 for cooling. The heat-conducting component 5 is thermally connected to the heat source surface of the cooling component 3 and a heat dissipation component 6 at a first position and a second position, respectively, to conduct heat dissipation from the cooling component 3. The heat-conducting component 5 has a first sidewall 501 and a second sidewall 502 opposite to each other. The first sidewall 501 is at least partially thermally connected to the heat source surface of the cooling component 3, and the second sidewall 502 generates conductive heat. The second sidewall 502 defines at least a portion of an airflow duct 51, and the conductive heat is discharged with the airflow within the airflow duct 51.

[0027] In this embodiment, the heat-conducting component 5 adopts a VC heat dissipation plate, which has a small structure and good heat dissipation effect. The heat-conducting component 5 is a thin plate structure with a first sidewall 501 and a second sidewall 502 on its two sides. The side facing the light-transmitting crystal 4 is the first sidewall 501. The bottom end of the first sidewall 501 is thermally connected to the heat source surface of the cooling component 3 and conducts heat to the heat sink 6 through the space between the first sidewall 501 and the second sidewall 502. During the conduction process, conductive heat is generated on the second sidewall 502. By defining at least part of the air flow channel 51 in the second sidewall 502 of the heat-conducting component 5, the conductive heat on the second sidewall 502 of the heat-conducting component 5 can be discharged when the air flows through the air flow channel 51. This effectively solves the problem of the accumulation of conductive heat in the shell 1 of the heat-conducting component 5 and improves the heat dissipation efficiency of the heat-conducting component 5, thereby improving the heat dissipation efficiency and effect of the internal space of the shell 1 of the portable beauty device. It should be noted that the heat generated by the light source 2 and the cooling component 3 in the portable beauty device is the main heat that needs to be discharged from the inside of the outer shell 1. It can be discharged in a conventional way. This embodiment only designs and improves the discharge of conductive heat on the heat-conducting component 5 and describes it in detail. For other details not mentioned, please refer to the existing technology.

[0028] like Figure 2 As shown, in another embodiment, the heat-conducting component 5 can also be a combination of a VC heat spreader and a copper plate. The VC heat spreader is arranged on one side of the cooling element 3 as shown in the figure, while the copper plate can be attached to the opposite side as a supporting and stabilizing component for the VC heat spreader. That is, the side of the VC heat spreader facing the light-transmitting crystal 4 and connected to the cooling element 3 is the first sidewall 501, while the copper plate on the side away from the cooling element 3 is the second sidewall 502. Heat is transferred to the heat dissipation component 6 through the heat-conducting component 5, and also to the second sidewall 502 through the copper plate that is attached to it. This conductive heat is then conducted into the space in the form of thermal radiation. The second sidewall 502 defines at least part of the airflow duct 51. When the airflow passes through the airflow duct 51, it can dissipate the conductive heat on the second sidewall 502 of the heat-conducting component 5. This effectively solves the problem of the accumulation of conductive heat in the shell 1 of the heat-conducting component 5, and can improve the heat dissipation efficiency of the heat-conducting component 5, thereby improving the heat dissipation efficiency and effect of the internal space of the shell 1 of the portable beauty device.

[0029] In some embodiments, the portable beauty device also includes a fan 7 for supplying airflow to the airflow duct 51.

[0030] like Figure 3 and Figure 4As shown, in the portable beauty device, the fan 7 is located in the middle of the interior of the outer casing 1, and is used to provide the airflow required for heat dissipation inside the outer casing 1. In this embodiment, the airflow provided by the fan 7 is at least partially introduced into the airflow duct 51, which is an extension of the function of the existing fan 7 and does not affect the heat dissipation of the main body inside the outer casing 1. Of course, a guide can also be set at the end of the heat-conducting component 5 facing the fan 7 to actively divert the airflow into the airflow duct 51. During the flow of the airflow, the conductive heat on the surface of the second sidewall 502 is carried away and discharged.

[0031] In some embodiments, the housing 1 is provided with an exhaust port 11, which is directly opposite to the air outlet of the fan 7. Along the air outlet direction, the air flow duct 51 extends from the air outlet to the exhaust port 11.

[0032] like Figure 3 As shown, the exhaust vent 11 is located at the front end of the outer casing 1, and the fan 7 is located inside the middle of the outer casing 1. The outlet of the fan 7 faces the exhaust vent 11, and the airflow duct 51 extends along the airflow direction of the outlet. Figure 4 As shown, the airflow duct 51 has an extension length along the X direction, which facilitates the diversion of airflow into the airflow duct 51 and the direct discharge of airflow from the airflow duct 51 to the outside of the outer casing 1 through the exhaust port 11, thereby increasing the airflow velocity and shortening the airflow path, and improving heat dissipation efficiency.

[0033] In some embodiments, the portable beauty device further includes a circuit board 8, a light source 2 disposed on the circuit board 8, the light source 2 being located between the circuit board 8 and the heat sink 6, the circuit board 8 having an opening 81, the heat conductor 5 being disposed through the opening 81, and the first position and the second position being disposed on both sides of the circuit board 8.

[0034] like Figure 2 The first and second positions of the heat-conducting element 5 are the bottom and top ends of the first sidewall 501, respectively, used to conduct heat from the heat source surface of the cooling element 3 to the heat sink 6 for heat dissipation. The heat-conducting element 5 passes through the opening 81 on the circuit board 8, such as... Figure 2 Compared with existing technologies, the heat-conducting component 5 does not need to avoid the circuit board 8, so the heat-conducting component 5 can be configured to have a larger surface area for heat dissipation, thereby improving heat dissipation efficiency.

[0035] In some embodiments, the second sidewall 502 of the heat-conducting element 5 abuts against the sidewall of the opening 81.

[0036] like Figure 2As shown, the second sidewall 502 of the heat-conducting component 5 abuts against the sidewall of the opening 81, which facilitates the installation and positioning between the heat-conducting component 5 and the circuit board 8 and forms a better sealed assembly space. On the one hand, it can conduct heat dissipation of some of the heat accumulated on the circuit board 8, and on the other hand, it can isolate the heat source surface of the cooling component 3 from some of the circuit board 8.

[0037] In some embodiments, the housing 1 is provided with a light outlet 12, which is positioned opposite to the opening 81.

[0038] like Figure 3 The light-transmitting crystal 4 is set and fixed between the light outlet 12 and the opening 81. The light emitted by the light source 2 passes through the light-transmitting crystal 4 and is emitted to the light outlet 12 for beauty treatment. The light-transmitting crystal 4 is flush with the end face of the light outlet 12, and the light outlet 12 is directly opposite the opening 81, which reduces the light path distance and reduces the loss of light energy provided by the light source 2.

[0039] In some embodiments, the exhaust direction of the exhaust port 11 is perpendicular to the light emission direction of the light outlet 12.

[0040] like Figure 3 and Figure 4 The exhaust vent 11 discharges air in the X direction, which is consistent with the air outlet direction of the fan 7. The heat sink 6 and the light source 2 are arranged side by side between the air outlet and the exhaust vent 11. The air flow provided by the fan 7 can simultaneously ventilate and dissipate heat on the heat sink 6 and the light source 2, thereby improving the heat dissipation effect on the light source 2.

[0041] In some embodiments, along the length of the housing 1, the exhaust port 11 is located at the front end of the housing 1, and the light outlet 12 is located at the bottom of the housing 1. The light path of the light source 2 is short, resulting in less heat accumulation inside the housing 1. It is also convenient to place the exhaust port 11 at the front end, thereby reducing the airflow path and improving heat dissipation efficiency.

[0042] In some embodiments, the portable beauty device further includes a housing 9, which covers a heat sink 6 and is connected to a circuit board 8. A portion of the inner wall of the housing 9, a portion of the circuit board 8, and a portion of the second sidewall 502 of the heat-conducting element 5 form an airflow duct 51.

[0043] like Figure 2The inner wall of the cover 9 faces the circuit board 8 and the heat sink 6. The width of the cover 9 along the Y direction is greater than the width of the heat sink 6, thus forming an installation gap between the inner wall of one side of the cover 9 and the heat conductor 5. This installation gap forms an air flow channel 51 with part of the circuit board 8. When the air flows in the air flow channel 51, it has a heat dissipation and cooling effect on the second side wall 502 of the heat conductor 5, part of the surface of the circuit board 8, and part of the inner wall of the cover 9. In addition, the cover 9 achieves thermal isolation between the heat sink 6 and the outer shell 1, reducing the thermal impact of the heat radiation of the heat sink 6 on the outer shell 1, which is beneficial to improving the user experience of the handheld beauty device.

[0044] In some embodiments, the portable beauty device is provided with a heat dissipation channel 61, a portion of the inner surface wall of the housing 9 defines at least a portion of the heat dissipation channel 61, a heat dissipation component 6 is disposed within the heat dissipation channel 61, the heat dissipation channel 61 extends from the air outlet to the exhaust outlet 11 along the air outlet direction, and a heat conduction component 5 is isolated between the heat dissipation channel 61 and the air flow duct 51.

[0045] For example Figure 2 The top portion of the inner surface wall of the casing 9, the portion of the first sidewall 501 of the heat-conducting component 5 facing the heat sink 6, and the inner surface wall of one side of the casing 9 together define the top and sides of the heat sink 6, as shown in the figure. Figure 4 The cover 9 has a length that can extend in the X direction, and the end of the cover 9 facing the exhaust port 11 has an outward expansion structure, which facilitates the exhaust of airflow. By setting the cover 9 to cover the heat dissipation component 6, airflow ducts 51 and heat dissipation channels 61 are formed on both sides of the heat conduction component 5, thereby realizing the isolation of the heat dissipation component 6 and multi-channel heat dissipation, and improving the heat dissipation effect.

[0046] In some embodiments, the portable beauty device further includes a flow guide shroud 10, the inner sidewall of which defines at least a portion of a flow guide channel 21, the flow guide channel 21 extending along the air outlet direction, the light source 2 disposed within the flow guide channel 21, and the flow guide shroud 10 isolated between the flow guide channel 21 and the heat dissipation channel 61.

[0047] like Figures 2-4 The air guide shroud 10 is mounted on the circuit board 8. An air guide channel 21 is formed between the inner wall of the air guide shroud 10 and the circuit board 8. The light source 2 is located inside the air guide channel 21. A heat sink 6 is provided on the outer wall of the air guide shroud 10. A cover 9 is provided on the outer side of the heat sink 6. Three independent channels are formed in the YZ plane of the outer shell 1, namely the air flow pipe 51, the heat dissipation channel 61 and the air guide channel 21. The three channels are parallel to each other and are located between the air outlet of the fan 7 and the exhaust port 11 of the outer shell 1. The air flow path is short and the wind resistance is small, which is conducive to rapid exhaust and improves the heat dissipation efficiency.

[0048] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
