[0044] The beauty instrument 100 provided in this embodiment is mainly used for skin care, where the skin care can be beauty care or treatment. The skin can be the skin of a human body or the skin of an animal. The skin of a human body can be the skin of the face, the skin of the hands, the skin of the legs, the skin of the abdomen, or the skin of other parts of the human body.

[0045] Please refer to Figures 1 to 3 The beauty instrument 100 provided in the first embodiment of the present utility model includes:

[0046] The housing 10 is provided with an air inlet 11 and an air outlet 12 communicating with the interior thereof, and a light-transmitting portion 13 is formed at one end of the housing 10. The housing 10 is used as the main frame of the beauty instrument 100 to integrate the various components of the beauty instrument 100, and the various components of the beauty instrument 100 are integrated into a whole. The housing 10 can protect the various components of the beauty instrument 100 and prevent the various components from being hit by external forces.

[0047] In this embodiment, the air inlet 11 and the air outlet 12 are hollow structures, which can prevent large particles of impurities or pollutants from being sucked into the beauty instrument 100, ensuring the cleanliness of the interior of the beauty instrument 100; the light-transmitting portion 13 can be made of a transparent material to facilitate the light emitted by the main light-emitting device 20 to pass through, for example, it can be made of a transparent polymer material or a transparent inorganic material. The transparent polymer material can be PC, transparent ABS, etc.; the transparent inorganic material can be glass, sapphire, ruby, diamond, etc.

[0048] The main light emitting device 20 is installed in the housing 10 to emit light toward the light-transmitting portion 13. In this embodiment, the main light emitting device 20 may include a tungsten filament lamp or an LED lamp to emit at least one of red light and infrared light to the user's skin to meet the user's different skin care requirements. In other embodiments, the main light emitting device 20 may also be used to emit light of other wavelengths, but is not limited thereto.

[0049] The heat dissipation component is installed in the housing 10 to at least dissipate heat for the main light-emitting device 20 .

[0050] The heat dissipation components include:

[0051] The air guide structure 31 is formed with a heat dissipation channel 32, and the heat dissipation channel 32 has an air inlet end 33 and an air outlet end 34 arranged at intervals. The air outlet end 34 is opposite to and connected to the air outlet 12. The main light-emitting device 20 is installed in the heat dissipation channel 32 and is located between the air inlet end 33 and the air outlet end 34. At least a part of the air guide structure 31 located between the main light-emitting device 20 and the light-transmitting portion 13 is formed with a light-transmitting area so that the light of the main light-emitting device 20 can be emitted toward the light-transmitting portion 13 through the light-transmitting area.

[0052] In this embodiment, the air inlet end 33 and the air outlet end 34 of the heat dissipation channel 32 are arranged at intervals in the horizontal direction. Compared with the heat dissipation path design of the existing beauty instrument 100, the length of the heat dissipation channel 32 of the utility model is greatly shortened, which accelerates the discharge of heat inside the beauty instrument 100 from the air outlet 12, thereby further improving the heat dissipation efficiency and heat dissipation effect.

[0053] The fan 36 is installed in the housing 10 to drive the air outside the beauty instrument 100 to enter the housing 10 from the air inlet 11, and form a heat dissipation airflow that flows through the air inlet end 33, the main light-emitting device 20, the air outlet end 34, and the air outlet 12 in sequence. In this way, the airflow generated by the fan 36 does not blow toward the inside of the housing 10, but blows toward the main light-emitting device 20, and takes away the heat generated by the main light-emitting device 20 and discharges it through the air outlet 12, thereby achieving a heat dissipation effect.

[0054] In this embodiment, the fan 36 is a rotating impeller driven by a motor, which can generate strong wind to suck the air outside the beauty instrument 100 from the air inlet 11. After the impeller rotates, a continuous heat dissipation airflow is formed, and flows through the main light-emitting device 20 and is discharged from the air outlet 12 to take away the heat generated by the main light-emitting device 20, thereby avoiding damage or malfunction of the beauty instrument 100 due to long-term high temperature, thereby ensuring the normal operation of the beauty instrument 100 and extending the service life of the beauty instrument 100.

[0055] In some embodiments, the air inlet 11 and the air outlet 12 are respectively arranged on opposite sides of the outer shell 10. In this way, the heat dissipation channel 32 can be avoided from being bent in the outer shell 10, so as to minimize the length of the heat dissipation channel 32, accelerate the airflow to enter through the air inlet 11, and pass through the heat dissipation channel 32 and be discharged to the outside through the air outlet 12.

[0056] Please refer to Figure 4The housing 10 includes a first shell 14, a second shell 15 and an annular connector 16. The first shell 14 and the second shell 15 are detachably connected via the annular connector 16. A head panel 17 is disposed on an end face of the second shell 15 facing away from the first shell 14. The light-transmitting portion 13 is disposed on the head panel 17. The air inlet 11 and the air outlet 12 are respectively disposed on opposite sides of the annular connector 16. In this way, when the user takes the beauty instrument 100 to work, the fingers will not block the air inlet 11 and the air outlet 12, thereby ensuring the normal operation of the heat dissipation component.

[0057] In some embodiments, the air guide structure 31 includes a cover body 311 and a filter plate 312, and the cover body 311 and the filter plate 312 are connected to form a heat dissipation channel 32;

[0058] The filter plate 312 is located between the main light emitting device 20 and the light-transmitting portion 13 to at least partially form a light-transmitting area. The filter plate 312 is used to filter the light emitted by the main light emitting device 20 so that the light emitted by the main light emitting device 20 and irradiated to the light-transmitting portion 13 is infrared light.

[0059] In this embodiment, after the light passes through the filter 312, the unnecessary wavelengths are filtered out, so that the light of the set wavelength passes through the filter 312 and irradiates the light-transmitting portion 13 to act on the user's skin. The filter 312 can be made of optical glass or acrylic, and the filter 312 is used to select the wavelengths of light to be irradiated, so that the light irradiated on the skin meets the user's skin care needs.

[0060] In this embodiment, the main light emitting device 20 is used to emit infrared light with a wavelength of 760-1940nm toward the light-transmitting portion 13, which can promote the conversion of fibroblasts in the skin into myofibroblasts, which are the main producers of collagen, and thus can promote the production of collagen and enhance skin thickness. In addition, it can promote the reproduction of keratinocytes, accelerate keratin formation, and restore the skin barrier.

[0061] Of course, in other embodiments, the filter plate 312 is also used to filter the light emitted by the main light-emitting device 20 so that the light emitted by the main light-emitting device 20 and irradiated to the light-transmitting portion 13 is light of a target wavelength, such as infrared light of 760-1940nm, etc., but is not limited to this.

[0062] In some embodiments, the wind guide structure 31 further includes:

[0063] The wind guide cover 313 has a wind guide channel 314 formed inside. One end opening of the wind guide channel 314 is connected to the output end of the fan 36, and the other end opening of the wind guide channel 314 is connected to the air inlet end 33. The setting of the wind guide cover 313 allows the heat dissipation airflow generated by the fan 36 to be transmitted along a preset path. At the same time, the wind guide cover 313 is a linear design, which can achieve uniform air output and obtain a better heat dissipation effect.

[0064] In some embodiments, a seal is provided between the air guide cover 313 and the fan 36, such as a sealing silicone sleeve is provided between the air guide cover 313 and the fan 36, which is used to prevent the wind of the fan 36 from leaking from the gap between the air guide cover 313 and the fan 36, ensuring that the heat dissipation airflow flowing into the heat dissipation channel 32 is sufficient, thereby improving the heat dissipation effect.

[0065] Since the main light emitting device 20 emits invisible light, the user cannot determine whether the beauty instrument 100 is working or cannot observe the working range of the beauty instrument 100, which affects the user's usage experience.

[0066] Please refer to Figure 4 and Figure 5 The beauty instrument 100 of the present invention further includes an auxiliary light emitting device 40, which is disposed between the filter plate 312 and the light-transmitting portion 13, and is used to emit visible light to the light-transmitting portion 13. When the beauty instrument 100 is working, that is, when the main light emitting device 20 emits light through the light-transmitting area toward the light-transmitting portion 13 and acts on the skin, the auxiliary light emitting device 40 works synchronously, emitting visible light to the light-transmitting portion 13 and irradiating the skin. At this time, the visible light emitted by the auxiliary light emitting device 40 forms an action area on the skin, which is convenient for the user to determine whether the beauty instrument 100 is working and observe the action range of the beauty instrument 100, thereby improving the user's experience.

[0067] In some embodiments, a light-transmitting space 41 is formed between the filter plate 312 and the light-transmitting portion 13;

[0068] The auxiliary light-emitting device 40 includes a first circuit board 42 and at least one lamp bead 43. The first circuit board 42 is arranged between the filter plate 312 and the light-transmitting portion 13. At least one lamp bead 43 is installed on the surface of the first circuit board 42 facing the filter plate 312, and at least part of the light emitted by the lamp bead 43 is laterally irradiated to the light-transmitting space 41 and then to the light-transmitting portion 13 through the light-transmitting space 41.

[0069] In this embodiment, the lamp bead 43 can be an RGB lamp bead. The three primary colors in the RGB lamp bead are red, blue, and green. Various colors can be formed by matching RGB, and then white light or other colorful lights are emitted to display different colors. Of course, in other embodiments, the lamp bead 43 can also be a white light lamp bead, but it is not limited to this.

[0070] In some embodiments, the beauty instrument 100 also includes a second circuit board 21, which is disposed in the outer shell 10 and outside the cover body 311. The two ends of the main light-emitting device 20 are respectively electrically connected to the second circuit board 21 through at least one electrical connector 22 passing through the cover body 311, so that the main light-emitting device 20 is suspended in the heat dissipation channel 32.

[0071] In this embodiment, the main light emitting device 20 is suspended in the heat dissipation channel 32, so that the heat dissipation airflow generated by the fan 36 almost entirely flows through the periphery of the main light emitting device 20 to take away the heat generated by the main light emitting device 20, thereby further improving the heat dissipation effect.

[0072] In some embodiments, a bracket 18 is disposed on the inner side of the housing 10 near the light-transmitting portion 13, the bracket 18 is hollow to form a light-transmitting space 41, and the inner peripheral wall of the bracket 18 in the light-transmitting space 41 is a reflective surface 181, which is used to reflect the light projected thereon toward the light-transmitting portion 13. The light emitted by the auxiliary light-emitting device 40 can be reflected by the reflective surface 181 and then emitted through the light-transmitting portion 13 and gathered onto the user's skin, thereby achieving a better focusing effect and improving the utilization of light energy.

[0073] The filter plate 312 is mounted on the bracket 18 and is disposed opposite to the light-transmitting space 41. The auxiliary light-emitting device 40 is mounted on the bracket 18 and is spaced apart from the filter plate 312.

[0074] In this embodiment, the first circuit board 42 can be a hard circuit board, which can be a ring-shaped rectangular circuit board, and multiple lamp beads 43 are spaced and distributed on the hard circuit board for easy assembly. Of course, in other embodiments, the first circuit board 42 can also be a flexible circuit board, and the first circuit board 42 can also be other shapes, such as a ring, etc., which is not limited in the embodiment of the present application.

[0075] In some embodiments, the beauty instrument 100 further includes a reflector 44, which is disposed outside the main light-emitting device 20 and is used to reflect the light projected thereon toward the light-transmitting portion 13. The light emitted by the main light-emitting device 20 can be reflected by the inner wall of the reflector 44 and then emitted through the light-transmitting portion 13 and gathered onto the user's skin, thereby achieving a better focusing effect and improving the utilization of light energy.

[0076] Please refer to Figure 6 , the beauty instrument 100 further includes:

[0077] At least one set of electrode assemblies 50 is at least partially exposed outside the housing 10 for outputting microcurrent to the skin.

[0078] Among them, each group of electrode components 50 includes at least one first electrode 51 and at least one second electrode 52, and at least one first electrode 51 and at least one second electrode 52 are respectively arranged at intervals on the peripheral side of the light-transmitting portion 13, and each first electrode 51 forms an electrode pair with a second electrode 52, that is, the polarity of the first electrode 51 and the second electrode 52 is opposite, such as one uses a positive electrode and the other uses a negative electrode. When the two are in contact with the skin at the same time, a loop can be formed to output microcurrent to the skin. Microcurrent can stimulate muscle fiber contraction, increase muscle tension, and enhance muscle strength and firmness. At the same time, current stimulation of the dermis will also promote cells to produce more adenosine triphosphate (ATP), and ATP is a key substance for collagen production. Therefore, microcurrent massage of the skin can accelerate the production of collagen, thereby achieving the effect of tightening, lifting and slimming the face.

[0079] In this embodiment, the electrode assembly 50 is at least partially exposed outside the outer shell 10, which may include a situation where the electrode assembly 50 is protruding outside the outer shell 10, a situation where the electrode assembly 50 is flush with the surface of the outer shell 10, or a situation where the electrode assembly 50 is recessed at a certain distance from the surface of the outer shell 10. The purpose is to enable the electrode assembly 50 to output microcurrent to the skin during the process of contact between the electrode assembly 50 and the skin.

[0080] Please refer to Figure 7 , two or more first electrodes 51 are provided, and the two or more first electrodes 51 are connected by a first conductive member 53 to increase the connection stability between the group of first electrodes 51; and / or,

[0081] Two or more second electrodes 52 are provided, and the two or more second electrodes 52 are connected by a second conductive member 54 to increase the connection stability between the group of second electrodes 52 .

[0082] In some embodiments, a shading member is disposed in the housing 10 and is spaced apart from the air outlet 12 , so as to reduce light leakage from the air outlet 12 of the housing 10 .

[0083] In this embodiment, the shading member can be a dustproof net, which plays the role of shading and dustproofing. It can prevent large particles of impurities or pollutants from the outside from being sucked into the beauty instrument 100 through the air outlet 12, thereby ensuring the cleanliness of the interior of the beauty instrument 100.
