Detailed Implementation

[0027] Typical embodiments embodying the features and advantages of this utility model will be described in detail in the following description. It should be understood that this utility model can have various variations in different embodiments, all of which do not depart from the scope of this utility model, and the descriptions and illustrations therein are for illustrative purposes only and not intended to limit this utility model.

[0028] In the description of this application, it should be understood that, in the embodiments shown in the accompanying drawings, the indications of direction or positional relationships (such as up, down, left, right, front, and back) are merely for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. These descriptions are appropriate when these elements are in the positions shown in the accompanying drawings. If the description of the positions of these elements changes, these directional indications also change accordingly.

[0029] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the stated features. In the description of this application, "a plurality of" means two or more, unless otherwise explicitly specified.

[0030] This application provides a beauty device that can perform anti-wrinkle, hair removal, skin rejuvenation, anti-inflammatory and acne-reducing effects, but is not limited to these.

[0031] See Figures 1 to 3 The beauty device includes a housing 10, a light-emitting component 20, a light-transmitting cooling element 30, a cooling plate 40, a cooling fan 50, a lamp tube heat sink 60, and a cooling heat sink 70. The light-emitting component 20, light-transmitting cooling element 30, cooling plate 40, cooling fan 50, lamp tube heat sink 60, and cooling heat sink 70 are mounted on the housing 10. The light-emitting component 20 includes a lamp tube 23, which emits light for beauty purposes and directs it towards the area to be treated, performing beauty treatments such as hair removal or skin rejuvenation. The lamp tube heat sink 60 dissipates heat from the lamp tube 23. The light-transmitting cooling element 30 is located in the light path of the lamp tube 23 and has a contact surface 31 that contacts the area to be treated, providing a cooling effect. The cooling plate 40 is connected to the light-transmitting cooling element 30 and transfers cooling energy to it. The cooling radiator 70 is connected to the cooling plate 40, so that the cooling plate 40 can transfer heat to the cooling radiator 70 and dissipate heat through the cooling radiator 70.

[0032] The housing 10 defines the overall shape of the beauty device, which can be circular, oval, rectangular, or other shapes. The housing 10 can have an internal cavity structure. The light-emitting component 20, the light-transmitting cooling component 30, the cooling plate 40, the cooling fan 50, the lamp tube heat sink 60, and the cooling heat sink 70 are installed inside the housing 10 and fixed relative to the housing 10 to prevent the light-emitting component 20, the light-transmitting cooling component 30, the cooling plate 40, the cooling fan 50, the lamp tube heat sink 60, and the cooling heat sink 70 from sliding or falling off, thereby ensuring the stability of the internal structure of the beauty device.

[0033] The housing 10 has a light outlet 11, a heat dissipation outlet 12, and a heat dissipation inlet 13, which are spaced apart and located on different sides of the housing 10. When the beauty device is in operation, the light outlet 11 faces the area to be treated, while the heat dissipation outlet 12 is located on a different side of the housing 10 than the light outlet 11, thus preventing the hot air from blowing directly towards the user and improving the user experience. Similarly, the heat dissipation outlet 12 is located on a different side of the housing 10 than the heat dissipation inlet 13, preventing the hot air from directly entering the beauty device through the heat dissipation inlet 13, thereby improving the device's heat dissipation effect.

[0034] In some embodiments, the housing 10 is further provided with heat dissipation holes 14, which are used for natural heat dissipation of devices installed inside the housing 10, thereby improving the heat dissipation effect of the beauty device.

[0035] exist Figure 1 In the illustrated embodiment, the front end of the housing 10 is provided with a working plane 15, and the light emission port 11 is disposed on the working plane 15. The housing 10 is also provided with a detection port (not shown in the figure). The detection port and the light emission port 11 are both arranged on the same side of the housing 10, and the detection port and the light emission port 11 are adjacent to each other and spaced apart.

[0036] See Figure 2 and Figure 3 The light-emitting component 20 includes a reflector 21, a filter 22, and a lamp tube 23. The reflector 21 is a cup-shaped structure with one open end, facing the light outlet 11. The lamp tube 23 is installed inside the reflector 21. The side of the reflector 21 facing the lamp tube 23 has a reflective surface to ensure that the cosmetic light emitted by the lamp tube 23 completely passes through the filter 22 and is directed towards the light outlet 11, thereby improving light utilization and ensuring the cosmetic effect. The filter 22 is located on one side of the opening of the reflector 21 and in the light path of the lamp tube 23. The filter 22 can filter the light emitted by the lamp tube 23 to obtain the corresponding cosmetic light, thereby achieving the corresponding cosmetic effect.

[0037] Preferably, the filter 22 is disposed at the opening of the reflector cup 21 and seals the opening of the reflector cup 21, so that a closed mounting cavity is formed inside the reflector cup 21. The lamp tube 23 is installed in this mounting cavity, so that external dust cannot accumulate on the lamp tube 23, thereby giving the beauty device a good dustproof effect and preventing the light emission effect of the lamp tube 23 from being affected by dust accumulation.

[0038] The lamp tube 23 can be a xenon lamp tube or a halogen lamp, etc. This application describes an embodiment in which the lamp tube 23 is a xenon lamp tube, but the lamp tube 23 is not limited to a xenon lamp tube.

[0039] The electrodes 231 at both ends of the lamp tube 23 are connected to the power supply circuit, and the power supply circuit supplies power to the lamp tube 23 so that the lamp tube 23 emits a strong pulse light source of a specific wavelength to achieve the effect of hair removal or skin rejuvenation. Among them, the electrodes 231 of the lamp tube 23 are the main heat-generating parts of the lamp tube 23.

[0040] A light-transmitting cooling compress 30 is disposed at the light outlet 11, and is spaced apart from the light outlet 23 along the light emission direction of the lamp tube 23. The light-transmitting cooling compress 30 has a contact surface 31 for contact with the user's skin. The contact surface 31 is located at and flush with the light outlet 11, that is, the contact surface 31 is flush with the working plane 15 at the front end of the housing 10, to facilitate contact with the user's skin and ensure the cooling effect. The light-transmitting cooling compress 30 can continuously cool the user's skin during the operation of the lamp tube 23, reducing the burning sensation and improving the user experience. In other embodiments, the contact surface 31 of the light-transmitting cooling compress 30 may also protrude from the working plane 15 of the housing 10.

[0041] It should be noted that the light-transmitting cooling compress 30 can be made of materials with good light transmittance and thermal conductivity, such as sapphire (AlO), quartz, or K glass. By using a light-transmitting cooling compress 30 with good light transmittance and thermal conductivity, it is possible to avoid blocking the light emitted by the lamp tube 23, ensuring the amount of light emitted, and also to ensure that the cooling plate 40 described below can quickly cool the light-transmitting cooling compress 30, thereby rapidly cooling the skin surface, reducing heat transfer to the skin, and thus improving the user experience.

[0042] The cooling pad 40 is in contact with the conductive surface of the light-transmitting cooling compress 30, which can continuously remove heat from the light-transmitting cooling compress 30, thereby reducing the temperature of the light-transmitting cooling compress 30 and keeping it at a low temperature to maintain the cooling effect. Figure 2 In the illustrated embodiment, the conductive surface of the light-transmitting cooling compress 30 can be located on the side wall of the light-transmitting cooling compress 30 to facilitate its contact with the cooling pad 40. The cooling pad 40 can be a semiconductor cooling pad, or it can be a compression cooling pad, absorption cooling pad, or other types of cooling pads.

[0043] In some embodiments of this application, the cooling chip 40 is a semiconductor cooling chip, which can form a cold surface (not shown in the figure) for absorbing heat and a hot surface (not shown in the figure) for releasing heat when energized. The cold surface is in contact with the conductive surface of the light-transmitting cooling compress 30, and can gradually remove the temperature from the conductive surface, so that the light-transmitting cooling compress 30 can be kept at a low temperature, thus ensuring the cooling effect of the light-transmitting cooling compress 30.

[0044] The cooling fan 50 is installed inside the housing 10 and is located on the side of the reflector cup 21 away from the light-transmitting cooling pad 30, so that the cooling fan 50 will not affect the light output of the lamp tube 23 inside the reflector cup 21.

[0045] See Figures 4 to 9 The cooling fan 50 includes a fan housing 51 and a fan 52 disposed within the fan housing 51. The fan housing 51 has a fan outlet 511 and a fan inlet 512. When the fan 52 rotates within the fan housing 51, it can draw air from outside the fan housing 51 into the fan inlet 512 and blow it out from the fan outlet 511. The fan inlet 512 is located inside the housing 10, and the fan outlet 511 corresponds to the cooling outlet 12 on the housing 10, allowing the airflow blown from the fan outlet 511 to be discharged from the cooling outlet 12 on the housing 10.

[0046] In one embodiment, the cooling fan 50 is a centrifugal fan, meaning it has an axial intake and radial exhaust structure. The second fan inlet 5122 communicates with the cooling air inlet 13 on the housing 10, and the fan outlet 511 is located on one radial side of the fan housing 51. The fan inlet 512 includes a first fan inlet 5121 and a second fan inlet 5122, which are respectively located at opposite axial ends of the fan housing 51. When the fan 52 rotates inside the fan housing 51, airflow from outside the fan housing 51 can enter the interior of the fan housing 51 through the first fan inlet 5121 and the second fan inlet 5122. In other embodiments, the cooling fan 50 can also be an axial flow fan, with both the first fan inlet 5121 and the second fan inlet 5122 located on the side where the axial flow fan intakes.

[0047] A lamp heat sink 60 is disposed inside the housing 10 and is connected to the lamp tube 23, allowing heat from the lamp tube 23 to be transferred to the lamp heat sink 60. The lamp heat sink 60 is at least partially located at the first fan inlet 5121. The cooling fan 50 draws air from the lamp heat sink 60 into the fan housing 51 and blows it out onto the cooling outlet 12 to dissipate heat from the lamp heat sink 60. Since the housing 10 is not completely sealed, air from other locations inside the housing 10 can pass through the lamp heat sink 60 and enter the fan housing 51 under the negative pressure created by the cooling fan 50, thereby continuously removing heat from the lamp heat sink 60 and dissipating heat from the lamp tube 23. Therefore, the lamp tube 23 exchanges heat with the airflow through the lamp heat sink 60, increasing the heat dissipation area and improving the heat dissipation effect of the lamp tube 23, preventing a large amount of heat from accumulating inside the housing 10 of the beauty device and causing damage to other components.

[0048] The lamp tube heat sink 60 includes a thermally conductive connecting plate 61 and multiple heat dissipation fins 62. The thermally conductive connecting plate 61 and the heat dissipation fins 62 can be made of materials with good thermal conductivity, such as copper sheets. One end of the thermally conductive connecting plate 61 is connected to the lamp tube 23, and the other end extends to the outside of the first fan inlet 5121, allowing heat from the lamp tube 23 to be transferred to the first fan inlet 5121 through the thermally conductive connecting plate 61. Multiple heat dissipation fins 62 are spaced apart at the end of the thermally conductive connecting plate 61 near the fan inlet 512. The gaps between adjacent heat dissipation fins 62 form airflow channels, ensuring that the outer surface of each heat dissipation fin 62 is in contact with the gas, thereby increasing the contact area between the lamp tube heat sink 60 and the gas and improving the heat exchange effect.

[0049] Preferred options, please refer to Figure 7 The heat sink 60 is connected to the electrode 231 of the lamp tube 23, that is, the heat-conducting connecting piece 61 of the heat sink 60 is connected to the electrode 231 of the lamp tube 23. Since the electrode 231 of the lamp tube 23 is the main heat-generating part of the lamp tube 23, the heat at the electrode 231 is directly conducted away, which effectively prevents the heat from accumulating in the lamp tube 23, improves the heat dissipation effect, and avoids the problem that a large amount of heat can easily accumulate in the shell 10 of the beauty device, causing damage to other components.

[0050] In one embodiment, the electrodes 231 at both ends of the lamp tube 23 are respectively connected to a lamp tube heat sink 60, and the two lamp tube heat sinks 60 are spaced apart to avoid short circuit between the two electrodes 231 of the lamp tube 23. Figure 4 In the embodiment shown, the heat dissipation fins 62 of the two lamp tube heat sinks 60 are arranged side by side on the outside of the first fan air inlet 5121, making the structure more compact.

[0051] It should be noted that a vent can also be provided on the housing 10 to communicate with the first fan inlet 5121 and the outside of the housing 10, so that external gas enters the fan housing 51 through the vent and the first fan inlet 5121, and the gas dissipates heat from the lamp tube heat sink 60 when it passes between the vent and the first fan inlet 5121.

[0052] See Figures 4 to 9 The cooling radiator 70 is disposed inside the housing and is connected to the cooling fin 40, allowing the cooling fin 40 to transfer heat to the cooling radiator 70. The cooling radiator 70 is at least partially located between the heat dissipation air inlet 13 and the second fan air inlet 5122, so that the airflow passing through the heat dissipation air inlet 13 can come into contact with the cooling radiator 70 to dissipate heat from the cooling radiator 70.

[0053] In one embodiment, the cooling radiator 70 includes a heat pipe 71 and multiple heat sinks 72, which are disposed outside the second fan inlet 5122. Specifically, the multiple heat sinks 72 are arranged at intervals between the cooling inlet 13 and the second fan inlet 5122, forming a ventilation channel between adjacent heat sinks 72 for external airflow. This allows air entering from the cooling inlet 13 to pass through the ventilation channel and the second fan inlet 5122 into the fan housing 51, and the air carries away heat from the heat sinks 72 as it passes through the ventilation channel. One end of the heat pipe 71 is in contact with the hot surface of the cooling plate 40 to carry away heat from the hot surface, and the other end of the heat pipe 71 is connected to the heat sink 72 to ultimately transfer the heat from the hot surface to the heat sink 72. That is, the heat sink 72 is connected to the hot surface of the cooling plate 40 through the heat pipe 71.

[0054] The cooling heat sink 70 also includes a heat-conducting plate 73, which is located at the end of the heat-conducting pipe 71 away from the heat sink 72. The heat-conducting pipe 71 is in contact with the hot surface of the cooling plate 40 through the heat-conducting plate 73, which increases the contact area between the heat-conducting pipe 71 and the cooling plate 40 and improves the heat exchange efficiency between the heat-conducting pipe 71 and the cooling plate 40.

[0055] The heat pipe 71 can be made of a material with good thermal conductivity, such as copper. The heat sink 72 and the heat-conducting plate 73 can also be made of a material with good thermal conductivity, such as copper.

[0056] The lamp heat sink 60, cooling fan 50, and cooling heat sink 70 are stacked, with the lamp heat sink 60 and cooling heat sink 70 located on opposite sides of the cooling fan 50 along its axial direction. This optimizes the space occupied by the lamp heat sink 60, cooling fan 50, and cooling heat sink 70, making the structure more compact and reducing the space they occupy inside the housing 10, thus improving the space utilization rate within the housing 10. Furthermore, since the lamp heat sink 60 and cooling heat sink 70 are located on opposite sides of the cooling fan 50 along its axial direction, the airflow passing through both the lamp heat sink 60 and cooling heat sink 70 is reduced, improving the heat dissipation effect.

[0057] It should be noted that the cooling fan 50 may also have only one fan inlet 512. When the fan 52 rotates inside the fan housing 51, the external airflow passes through the lamp heat sink 60 and the cooling heat sink 70 into the fan housing 51 and is discharged from the heat dissipation outlet 12. In this embodiment, the lamp heat sink 60 and the cooling heat sink 70 may be stacked or arranged side by side.

[0058] The beauty device also includes a skin tone detector 80 disposed inside the housing 10. The skin tone detector 80 is adjacent to and located on one side of the light-transmitting cooling compress 30. The skin tone detector 80 can emit detection light for detecting skin tone. The detection light reaches the user's skin through the aforementioned detection port, is reflected after contacting the user's skin, and is reflected back to the skin tone detector 80 through the detection port. The skin tone detector 80 can obtain the skin tone information of the user's skin.

[0059] The housing 10 contains a drive circuit board (not shown in the figure). This drive circuit board is electrically connected to the lamp tube 23 and the skin tone detector 80. The drive circuit board can receive the skin tone information of the user's skin obtained by the skin tone detector 80, and control the light intensity of the beauty light emitted by the lamp tube 23 according to the skin tone information. In this way, the light intensity of the beauty light can be automatically adjusted according to different skin tones to avoid skin damage and improve the safety performance of the beauty device.

[0060] The beauty device also includes a support 90, which is mounted on the housing 10. The cooling fan 50, lamp heat sink 60, light-emitting component 20, light-transmitting cooling element 30, cooling plate 40, cooling heat sink 70, and skin tone detector 80 are all integrated onto the support 90. This allows the cooling fan 50, lamp heat sink 60, light-emitting component 20, light-transmitting cooling element 30, cooling plate 40, cooling heat sink 70, skin tone detector 80, and support 90 to form a single module, ensuring the stability of the beauty device's internal structure.

[0061] exist Figure 5 In the illustrated embodiment, the bracket 90 includes a fan bracket 91 and a cooling pad mounting bracket 92. The cooling fan 50 and the light-emitting component 20 are respectively fixed on both sides of the fan bracket 91. The light-transmitting cooling pad 30, the cooling heat sink 70, and the skin tone detector 80 are all fixed on the cooling pad mounting bracket 92. The mounting bracket 90 is fixedly connected to the fan bracket 91. The lamp heat sink 60 is fixedly connected to the light-emitting component 20. The cooling plate 40 is fixedly connected to the light-transmitting cooling pad 30, thereby making the cooling fan 50, the lamp heat sink 60, the light-emitting component 20, the light-transmitting cooling pad 30, the cooling plate 40, the cooling heat sink 70, the skin tone detector 80, and the bracket 90 form an integral structure.

[0062] The fan bracket 91 blocks the light-emitting component 20 and the cooling fan 50, so that the airflow generated by the cooling fan 50 does not pass directly through the location of the light-emitting component 20, effectively preventing dust brought by the airflow from accumulating on the light-emitting component 20.

[0063] The beauty device also includes an insulating isolator 93, which is mounted on the bracket 90 and located between the two lamp tube heat sinks 60, which are respectively connected to the electrodes 231 at both ends of the lamp tube 23. The insulating isolator 93 is non-conductive, thus isolating the two lamp tube heat sinks 60 from each other. Since the two electrodes 231 of the lamp tube 23 are respectively connected to the two lamp tube heat sinks 60, and the lamp tube heat sinks 60 are both made of metal, the insulating isolator 93 between the two lamp tube heat sinks 60 can prevent the metal heat dissipation fins 62 of the two lamp tube heat sinks 60 from contacting due to vibration or other reasons, thus preventing short circuits.

[0064] In one embodiment, the insulating isolator 93 and the fan bracket 91 are integrally formed. The insulating isolator 93 extends along the direction of the first fan inlet 5121, and the end of the insulating isolator 93 away from the fan bracket 91 is flush with or nearly flush with the end of the lamp tube heat sink 60 away from the lamp tube 23. In other embodiments, the insulating isolator 93 may also be separately provided from the fan bracket 91, and the insulating isolator 93 may be fixed to the bracket 90 or the housing 10 by means of snap-fit, screw connection or other methods.

[0065] See Figure 2 and Figure 3 The beauty device also includes an energy storage capacitor 100 for storing and outputting electrical energy. The energy storage capacitor 100 is located inside the housing 10 and is electrically connected to the lamp tube 23, which enables the lamp tube 23 to emit light for beauty purposes.

[0066] It should be noted that the beauty device also includes a voltage converter (not shown in the figure) located inside the housing 10. The voltage converter can work in conjunction with the energy storage capacitor 100 to enable the lamp tube 23 to achieve a flashing mode, thereby improving the beauty effect of the beauty device.

[0067] The bottom of the housing 10 is provided with a charging port 110, which can be used to connect an external charging cable to charge the energy storage capacitor 100.

[0068] In some embodiments of this application, the beauty device also includes a display screen 120. The display screen 120 is electrically connected to the drive circuit board and is capable of receiving electrical signals from the drive circuit board to display the electrical signals on the display screen 120, thereby reflecting the functional mode of the beauty device in a timely manner.

[0069] The beauty device also includes multiple buttons 130. When a button 130 is pressed, the conductive contacts on the drive circuit board are turned on, and the drive circuit board outputs an electrical signal to control the light emission state of the lamp tube 23, thereby adjusting the working mode of the lamp tube 23. For example: the power button 130 (turns on the lamp tube 23), the continuous irradiation button 130, the screen flash button 130, and the brightness increase or decrease button 130, etc.

[0070] The beauty device of this application includes a housing 10, a light-emitting component 20, a cooling fan 50, and a lamp tube heat sink 60. The housing 10 has a light outlet 11 and a heat dissipation outlet 12. The cooling fan 50 and the lamp tube 23 of the light-emitting component 20 are disposed inside the housing 10. The light emitted by the lamp tube 23 passes through the light outlet 11 and is directed towards the user's area to be treated, thereby achieving beauty care for the user. The lamp tube heat sink 60 is directly connected to the electrode 231 of the lamp tube 23, so that the electrode of the lamp tube 23 transfers heat to the lamp tube heat sink 60. The lamp tube heat sink 60 is at least partially located at the fan inlet 512 of the cooling fan 50. The cooling fan 50 draws the gas from the lamp tube heat sink 60 into the cooling fan 50 and blows it out onto the heat dissipation outlet 12, thereby dissipating the hot gas from the lamp tube heat sink 60 and achieving heat dissipation of the lamp tube heat sink 60. The electrode 231 of the lamp tube 23 is the main heat-generating part of the lamp tube 23. The lamp tube heat sink 60 is directly connected to the electrode 231 of the lamp tube 23, so that the heat of the lamp tube 23 is quickly transferred to the lamp tube heat sink 60. Furthermore, the lamp tube 23 exchanges heat with the airflow through the lamp tube heat sink 60, which increases the heat dissipation area and improves the heat dissipation effect of the lamp tube 23. This avoids the problem that a large amount of heat can easily accumulate in the shell 10 of the beauty device, causing damage to other components.
