Description

Technical Field

[0001] This application belongs to the field of beauty equipment technology, specifically relating to a beauty instrument. Background Technology

[0002] Currently, most optical beauty devices on the market use xenon flash lamps as the light source. IPL (Intense Pulsed Light) devices emit a broad-spectrum visible light that can penetrate the epidermis and be absorbed by the hair follicles within the dermis. The melanin in the hair follicle and hair shaft is the primary target of photothermal action because melanin absorbs light energy of specific wavelengths. When the melanin in the hair follicle absorbs light energy, this energy is converted into heat energy, causing the hair follicle temperature to rise. This heat energy is transmitted through the hair to the depths of the hair follicle, continuously damaging the hair follicle's growth tissue. The regenerating tissue of the hair follicle dies due to thermal burns caused by the high temperature, thus achieving the effect of hair removal. Because light energy is mainly absorbed by melanin, and the melanin content in hair follicles and hair shafts is much higher than in normal skin tissue, IPL treatments cause less damage to the surrounding normal skin tissue.

[0003] However, different skin tones absorb and react to light differently, and some beauty devices currently do not have skin tone detection capabilities, resulting in poor product safety. Utility Model Content

[0040] Figure 1 A cross-sectional structural diagram of the beauty device provided in the embodiment of this application is shown. Figure 2 A three-dimensional structural schematic diagram of the beauty device provided in the embodiment of this application is shown. Figure 3 It shows Figure 1 A partial structural diagram of the skin tone detection module, the light-emitting component, and the cooling compress component.

[0041] See Figures 1 to 3 As shown, this application provides a beauty device 10, which includes a housing 100, a light-emitting element 200, a cold compress component 300, a skin color detection module 400, and a first circuit board 500.

[0042] With the assistance of the light-emitting element 200 and the cooling compress component 300, the beauty device 10 can simultaneously care for the user's skin and apply a cooling compress to the area to be treated, achieving dual benefits and enhancing the user experience. Furthermore, during the operation of the beauty device 10, the skin tone detection module 400 can acquire the user's skin tone information in real time and transmit this information to the first circuit board 500. The first circuit board 500 adjusts the intensity of the beauty light emitted by the light-emitting element 200 based on the skin tone information, thereby automatically adjusting the intensity of the beauty light according to the user's skin tone to reduce or avoid damage to the user's skin.

[0043] In some embodiments of this application, the housing 100 can be elliptical or other shapes, such as square or circular structures.

[0044] It should be noted that the housing 100 can define the overall shape of the beauty device 10.

[0045] In some embodiments of this application, see Figure 1 As shown, the housing 100 has an internal cavity structure, that is: the housing 100 includes a receiving space (not shown in the figure), and the light-emitting element 200, the cold compress assembly 300, the skin color detection module 400 and the first circuit board 500 are all located in the receiving space.

[0046] In some embodiments of this application, see Figure 1 or Figure 3 As shown, a light outlet 110 is provided on the housing 100. The light outlet 110 allows the cosmetic light emitted by the light-emitting element 200 to pass through, so as to perform cosmetic treatment on the user's area to be treated.

[0047] In some embodiments of this application, see Figure 1 or Figure 3 As shown, a detection port 120 is also provided on the housing 100. The detection port 120 and the light emission port 110 are both arranged on the same side of the housing 100, and are adjacent to and spaced apart from each other. The detection port 120 can be used to allow the detection light emitted by the skin color detection module 400 to pass through, so that the detection light can reach the user's skin. The detection port 120 can also be used to reflect the detection light reflected back from the user's skin back to the skin color detection module 400, so that the skin color detection module 400 can acquire the user's skin color information.

[0048] It should be noted that the light emission port 110 and the detection port 120 can be square, triangular, circular or elliptical, and the light emission port 110 and the detection port 120 can be the same shape or different shapes.

[0049] For example, see Figure 1 or Figure 3As shown, both the light outlet 110 and the detection port 120 are rectangular in shape, and the area of ​​the light outlet 110 is larger than the area of ​​the detection port 120, so as to avoid the detection light from interfering with the operation of the beauty light and to ensure the beauty effect of the beauty device 10.

[0050] In some embodiments of this application, the light-emitting element 200 may be disposed within the receiving space and fixed relative to the housing 100, so that the light-emitting element 200 may slide and fall off, thereby ensuring the stability of the light-emitting element 200 and thus ensuring the beauty effect of the beauty device 10.

[0051] Among them, see Figure 1 or Figure 3 As shown, the light-emitting element 200 can correspond to the light-emitting port 110. The light-emitting element 200 can emit light for beauty purposes. The beauty light can pass through the light-emitting port 110 and be directed at the area of ​​the user to be treated, so as to achieve a beauty effect on the user's skin.

[0052] In some embodiments of this application, see Figure 1 or Figure 3 As shown, the cooling compress component 300 can be disposed within the receiving space and on one side of the light-emitting element 200 in the direction of light emission, that is, above the light-emitting element 200 (with the side of the housing 100 acting on the user's skin as the top). The cooling compress component 300 has a contact surface for contacting the skin (not shown in the figure). During the operation of the light-emitting element 200, the contact surface of the cooling compress component 300 comes into contact with the user's skin to reduce the burning sensation generated by the light-emitting element 200 and improve the user experience.

[0053] In some embodiments of this application, see Figure 1 or Figure 3 As shown, the skin tone detection module 400 can be disposed within the receiving space, adjacent to and located on one side of the cooling compress component 300. The skin tone detection module 400 can emit detection light for detecting skin tone. The detection light reaches the user's skin through the detection port 120, is reflected after contacting the user's skin, and is reflected back to the skin tone detection module 400 through the detection port 120. The skin tone detection module 400 can obtain the skin tone information of the user's skin.

[0054] In some embodiments of this application, see Figure 1 As shown, the first circuit board 500 is fixed in the receiving space and electrically connected to the light-emitting element 200 and the skin color detection module 400. The first circuit board 500 can receive the skin color information of the user's skin obtained by the skin color detection module 400, and control the light intensity of the beauty light emitted by the light-emitting element 200 according to the skin color information, so as to automatically adjust the light intensity of the beauty light according to different skin colors and avoid skin damage.

[0055] This application solution uses a skin color detection module 400 to acquire the user's skin color information in real time. The first circuit board 500 automatically adjusts the light intensity of the beauty light emitted by the light-emitting element 200 based on the acquired user skin color information, so as to reduce or avoid heat damage to the user's skin and improve the product safety performance of the beauty device 10.

[0056] In some embodiments of this application, see Figure 1 or Figure 3 As shown, the skin color detection module 400 includes a second circuit board 410, a light emitting device 420, and a light sensing device 430.

[0057] The second circuit board 410 is electrically connected to the first circuit board 500 to facilitate information transmission. Multiple light emitting devices 420 are arrayed on the second circuit board 410, and all of the multiple light emitting devices 420 are electrically connected to the second circuit board 410. The second circuit board 410 can control the light emitting devices 420 to emit detection light.

[0058] The photosensitive device 430 is electrically connected to the second circuit board 410. The photosensitive device 430 can acquire the detection light emitted by the light emitting device 420 and the detection light reflected back by the user's skin, and convert the acquired detection light into an electrical signal and transmit it to the second circuit board 410. The second circuit board 410 can acquire the user's skin color information based on the detection light emitted by the light emitting device 420 and the detection light acquired by the photosensitive device 430. The photosensitive device 430 can be a photoelectric conversion device such as a photodiode or a photoresistor, but this application does not limit its specific type or kind.

[0059] It is understandable that the second circuit board 410 can detect skin color based on the difference in light absorption by different skin colors. That is, the second circuit board 410 can output skin color information based on the difference in light detected by the light sensor 430 before and after (the detection light emitted by the light emitting device 420 and the detection light reflected back from the user's skin).

[0060] After acquiring skin color information, the second circuit board 410 transmits the skin color information to the first circuit board 500 via a signal. The first circuit board 500 can control the light intensity of the beauty light emitted by the light-emitting element 200 according to the skin color information. That is, the light intensity of the beauty light can be adjusted according to the different light absorption and reaction of different skin colors, thereby reducing or avoiding skin thermal damage.

[0061] It should be noted that the light emitting device 420 can be a monochromatic diode, such as a blue, red, or green light-emitting LED, or it can be a white LED or a multi-color LED, to detect skin color based on the differences in light absorption of different skin colors, thereby improving the accuracy of skin color detection and thus better reducing or avoiding skin thermal damage.

[0062] In some embodiments of this application, a detection channel (not shown in the figure) is provided on the top of the housing 100. One end of the detection channel corresponds to the photosensor 430, and the other end is connected to the detection port 120. That is, the detection channel can be used to detect light emitted or light reflected back to the skin color detection module 400.

[0063] In some embodiments of this application, see Figure 1 and Figure 3 As shown, the skin color detection module 400 also includes a light guide 440. The light guide 440 is disposed in the detection channel. The light guide 440 can improve the transmission rate of the detection light, thereby improving the utilization rate of the detection light, allowing more detection light to be emitted from the detection port 120 or more detection light to be reflected back from the detection port 120, so as to improve the accuracy of skin color detection.

[0064] In some embodiments of this application, a reflective layer (not shown in the figure) or a light-shielding layer (not shown in the figure) is provided on the inner wall of the detection channel to further isolate external interference light, improve the purity of the detection light, and thus improve the accuracy of skin color detection.

[0065] In some other embodiments of this application, a reflective layer (not shown in the figure) is provided on the outer wall of the light guide 440 to further isolate external interference light, improve the purity of the detection light, and thus improve the accuracy of skin color detection.

[0066] In some embodiments of this application, see Figure 1 or Figure 3 As shown, the beauty device 10 also includes an auxiliary function module 600. The auxiliary function module 600 is located on the other side of the cooling component 300, that is, on the side of the cooling component 300 away from the skin color detection module 400. The skin color detection module 400 and the auxiliary function module 600 are respectively located on opposite sides of the cooling component 300.

[0067] Among them, see Figure 1 or Figure 3 As shown, the auxiliary function module 600 includes a third circuit board 610 and a functional unit 620. The functional module is electrically connected to the third circuit board 610 to enable it to perform its corresponding functions. The functional module can be an LED skin-beautifying module, a microcurrent EMS module, or an RF module, etc.

[0068] In some embodiments of this application, see Figure 1 or Figure 3 As shown, the housing 100 includes a top cover 130, which faces the area to be treated by the user. The top cover 130 has a light outlet 110, a detection port 120, and a detection channel.

[0069] It should be noted that, depending on the functional module, corresponding electrodes or light-transmitting windows are provided around the light outlet 110.

[0070] For example, when the functional module is an LED skin-beautifying module: multiple LED skin-beautifying lamp beads are arranged in an array on the third circuit board 610, and the top cover 130 can be set as a frosted light-transmitting window so that the beauty light emitted by the LED skin-beautifying lamp beads can penetrate and act on the skin.

[0071] In another example, when the functional module is a radio frequency (RF) module or a microcurrent (EMS) module: the top cover 130 has an opening at the position corresponding to the functional module so that the electrode can pass through to act on the skin and enhance the cosmetic effect.

[0072] In some embodiments of this application, see Figure 1 or Figure 3 As shown, the distance between the second circuit board 410 and the top cover 130 is greater than the distance between the third circuit board 610 and the top cover 130, so that the light emitted by the light emitting device 420 can reach the user's skin and return to the light sensing device 430 through the light guide 440, thereby improving the skin color detection effect.

[0073] In some embodiments of this application, see Figure 1 or Figure 3 As shown, the light-emitting component 200 includes a light-emitting body 210, a reflector 220, and a filter 230. The filter 230 is disposed in the light-emitting direction of the light-emitting body 210, and the reflector 220 is disposed on the light-emitting body 210 and connected to the filter 230, so that the beauty light generated by the light-emitting body 210 can completely pass through the filter 230 and be directed to the light outlet 110, thereby improving the utilization rate of beauty light and ensuring the beauty effect.

[0074] It is understandable that the filter 230 can filter the light emitted by the light source 210 to obtain the corresponding beauty light, thereby obtaining the corresponding beauty effect.

[0075] In addition, the light source 210 can be any light source that can emit light directly or through the filter 230, such as LED, xenon lamp, halogen lamp, thermal radiation lamp, tungsten filament lamp, etc., for skin treatments such as beauty hair removal.

[0076] In some embodiments of this application, see Figure 1 or Figure 3 As shown, the cooling compress assembly 300 may include a cooling compress 310 and a cooling element 320. The cooling element 320 can quickly cool down the cooling compress 310 so that the cooling compress 310 is in a low-temperature state when it comes into contact with the user's skin, thus ensuring the cooling effect.

[0077] Among them, the cooling component 310 can be made of materials with good light transmittance and good thermal conductivity, such as sapphire (Al2O3), quartz, or K9 glass.

[0078] It should be noted that the cooling compress 310 is located on the side of the filter 230 away from the light source. By using the cooling compress 310 with good light transmittance and thermal conductivity, it is possible to avoid blocking the light emitted by the light source 210 and ensure the amount of light emitted. At the same time, it is possible to ensure that the cooling component 320 can quickly cool down the cooling compress 310, thereby quickly cooling the skin surface, reducing heat transfer to the skin, and thus improving the user experience.

[0079] The cooling compress 310 has a contact surface (not shown in the figure) and a conductive surface (not shown in the figure). The contact surface contacts the area to be treated by the user, and the conductive surface is located on one side of the cooling compress 310, that is, the conductive surface is located on the side wall of the cooling compress 310.

[0080] In some embodiments of this application, see Figure 1 or Figure 3 As shown, the beauty device 10 also includes a mounting bracket 700. The mounting bracket 700 is fixed inside the housing 100 to prevent the mounting bracket 700 from shaking within the housing space.

[0081] The cold compress 310 is fixed in the receiving space by the fixing bracket 700, thereby limiting the position of the cold compress 310 in the receiving space, preventing shaking, and ensuring the cold compress effect.

[0082] The mounting bracket 700 can be an opaque structure so that the beauty light emitted by the light-emitting component 200 can completely pass through the cooling component 310 and be emitted from the light outlet 110, thus ensuring the light emission rate and thus ensuring the beauty effect.

[0083] It should be noted that the fixing frame 700 can be made of plastic, which has low thermal conductivity and will not release heat to the cooling compress 310, thus ensuring the cooling effect of the cooling compress 310. Of course, the fixing frame 700 can also be made of other materials.

[0084] In addition, the mounting bracket 700 has an opening on one side that exposes the conductive surface of the cooling patch 310 (not shown in the figure).

[0085] In some embodiments of this application, the cooling element 320 may be a semiconductor cooling chip, and the cooling element 320 may 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.

[0086] The cold surface fits into the conductive surface through the opening on the fixing frame 700, gradually removing the temperature from the conductive surface and keeping the cold compress 310 in a low-temperature state, thus ensuring the cooling effect of the cold compress 310.

[0087] Figure 4 This illustration shows a cross-sectional structural diagram of the heat dissipation device provided in an embodiment of this application, disposed within an accommodating space. Figure 5 This paper shows a cross-sectional view of the heat dissipation device provided in an embodiment of the present application, in which the air outlet channel and the air outlet are connected.

[0088] In some embodiments of this application, see Figure 4 As shown, the beauty device 10 also includes a heat dissipation device 800 disposed in the housing space. This heat dissipation device 800 can remove the heat from the hot surface of the cooling component 320 to ensure that the cooling component 320 can work continuously, thereby ensuring the cooling effect on the cooling compress component 310.

[0089] Among them, see Figure 4 and Figure 5 As shown, the heat dissipation device 800 includes a heat sink 810 and a conductive member 820. One end of the conductive member 820 is in contact with the hot surface of the cooling member 320 to remove heat from the hot surface of the cooling member 320. The other end of the conductive member 820 is connected to the heat sink 810, and the heat sink 810 can remove heat from the conductive member 820. That is, the heat on the hot surface of the cooling member 320 is removed through the conductive member 820 and the heat sink 810, thereby reducing the temperature of the hot surface of the cooling member 320, ensuring the working environment of the cooling member 320, and ensuring the cooling effect of the cooling member 310.

[0090] In some embodiments of this application, see Figure 1 and Figure 4 As shown, the conductive element 820 includes a heat sink 821. The heat sink 821 can be made of a material with good thermal conductivity, such as copper. One side of the heat sink 821 is in contact with the hot surface of the cooling element 320 to remove heat from the hot surface of the cooling element 320, that is, the heat from the hot surface of the cooling element 320 is transferred to the heat sink 821.

[0091] In some embodiments of this application, see Figure 1 and Figure 4 As shown, the conductive element 820 also includes a heat dissipation pipe 822. The heat dissipation pipe 822 can also be made of a material with good thermal conductivity, such as copper. One end of the heat dissipation pipe 822 is attached to the side of the heat sink 821 away from the cooling element 320 to remove heat from the heat sink 821. The other end of the heat dissipation pipe 822 is connected to the radiator 810 so that the heat on the heat dissipation pipe 822 can be transferred to the radiator 810.

[0092] In some embodiments of this application, see Figure 1 and Figure 4 As shown, the heat sink 810 includes a heat sink body 811, a cooling fan 812, and cooling fins 813.

[0093] Among them, see Figure 4 and Figure 5 As shown, the heat sink 811 adopts a volute-like structure to effectively guide airflow and improve gas flow. The heat sink 811 contains a first heat dissipation channel 8110, a second heat dissipation channel 8111, and an exhaust channel 8112. The first heat dissipation channel 8110 and the second heat dissipation channel 8111 are independent of each other; the gas within the first heat dissipation channel 8110 and the second heat dissipation channel 8111 will not flow into the second heat dissipation channel 8111, and vice versa, thus ensuring effective heat dissipation.

[0094] In some embodiments of this application, see Figure 4 and Figure 5 As shown, the housing 100 also has a first air inlet 140, a second air inlet 150, an air outlet 160, and a ventilation channel 170. The air outlet 160 is located on the side of the housing 100 away from the user, so that the hot air released from the air outlet 160 can be directed away from the user, improving the user experience. The second air inlet 150 is located at the bottom of the housing 100, meaning that the second air inlet 150 and the light outlet 110 are located on opposite sides of the housing 100. The first air inlet 140 can be located on the side wall of the housing 100, as long as it does not interfere with the air intake of the first air inlet 140 when the user holds the beauty device 10.

[0095] It should be noted that, see Figure 4 and Figure 5 As shown, one end of the first heat dissipation channel 8110 can be connected to the first air inlet 140, and the other end can be connected to the cooling fan 812. One end of the second heat dissipation channel 8111 can be connected to the side of the ventilation channel 170 away from the second air inlet 150, that is, the second heat dissipation channel 8111 is connected to the second air inlet 150 through the ventilation channel 170. Cooling air flowing in from the second air inlet 150 flows into the second heat dissipation channel 8111 through the ventilation channel 170. The other end of the second heat dissipation channel 8111 is connected to the cooling fan 812. One end of the exhaust channel 8112 is connected to the exhaust outlet of the cooling fan 812, and the other end is connected to the exhaust port 160.

[0096] It should be noted that, see Figure 4 and Figure 5 As shown, the light-emitting element 200 is disposed in the first heat dissipation channel 8110, the heat dissipation fin 813 is disposed in the second heat dissipation channel 8111, and the heat dissipation pipe 822 and the heat dissipation fin 813 are connected in the second heat dissipation channel 8111 so that the heat on the heat dissipation pipe 822 is transferred to the heat dissipation fin 813.

[0097] In some embodiments of this application, see Figure 4 and Figure 5As indicated by the middle arrow, the cooling fan 812 is located inside the heat sink body 811. Under the action of the cooling fan 812, the interior of the heat sink body 811 is under low pressure, while the outside is under high pressure. According to the pressure relationship, the external cooling air can enter the first heat dissipation channel 8110 through the first air inlet 140. The cooling air gradually carries away the heat generated by the light-emitting element 200, and the hot air that has absorbed the heat is then discharged into the cooling fan 812 through the first heat dissipation channel 8110. In addition, the external cooling air can also enter the second heat dissipation channel 8111 through the second air inlet 150 and the ventilation channel 170. The cooling air gradually carries away the heat from the heat dissipation fins 813 and the heat pipes 822, and the hot air that has absorbed the heat is then discharged into the cooling fan 812 through the second heat dissipation channel 8111.

[0098] See Figure 4 and Figure 5 As shown by the middle arrow, two streams of hot air converge in the cooling fan 812 and, under the action of the cooling fan 812, are discharged towards the air outlet 160 through the air outlet channel 8112. This discharges the hot air that has absorbed heat from the light-emitting component 200 and the heat sink 822, thereby reducing the temperature of the light-emitting component 200 and the heat sink 822. This lowers the internal temperature of the housing space and protects the electronic components inside. Furthermore, reducing the internal temperature of the housing space also prevents users from experiencing excessively high hand temperatures or sweating due to continuous contact with the hot body, improving the user experience.

[0099] In some embodiments of this application, a waterproof adhesive (not shown in the figure) is provided between the top cover 130 and the top of the fixing bracket 700 to prevent water stains from entering, ensuring that each electronic component is in a normal working environment, thereby ensuring the cosmetic effect.

[0100] In some embodiments of this application, see Figure 1 As shown, the beauty device 10 also includes an energy storage capacitor 900 for storage and output. The energy storage capacitor 900 is disposed in the housing space and electrically connected to the light-emitting element 200, which enables the light-emitting element 200 to emit light for beauty purposes.

[0101] It should be noted that, see Figure 1 As shown, the beauty device 10 also includes a voltage converter disposed in the housing space. The voltage converter can cooperate with the energy storage capacitor 900 to enable the light-emitting element 200 to achieve a flashing mode, thereby improving the beauty effect of the beauty device 10.

[0102] In addition, a charging port (not shown in the figure) is provided at the bottom of the housing 100. The charging port can be used with an external charging cable to charge the energy storage capacitor 900.

[0103] This application solution can acquire the user's skin tone information in real time by setting a skin tone detection module 400 inside the beauty device 10, and automatically adjust the light intensity of the beauty light emitted by the light-emitting element 200 according to the user's skin tone information, so as to reduce the heat damage to the user's skin and improve the product safety performance of the beauty device 10.
