Description

Technical Field

[0001] This utility model belongs to the technical field of hair removal devices, specifically relating to a laser hair removal device with cosmetic functions. Background Technology

[0002] Current laser hair removal devices generally focus on a single hair removal function, lacking integrated design for skin care. After hair removal, users need to use radio frequency devices, microcurrent devices, or phototherapy devices for follow-up repair and beauty treatments, which is cumbersome and costly. In addition, traditional devices mostly use a fixed power output mode, which cannot dynamically adjust laser parameters according to the user's skin tone differences. This makes users with dark skin prone to skin burns due to excessive photothermal exposure, limiting safety and universality. At the same time, single-function devices cannot meet consumers' needs for efficient and convenient care, resulting in a fragmented user experience. The market urgently needs an integrated solution that combines hair removal and beauty technologies. The shortcomings of existing technologies are mainly reflected in their single function, insufficient adaptability, and low efficiency, which restricts the overall competitiveness of the products.

Detailed Implementation

[0026] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0027] like Figure 1-6 As shown, this utility model provides a laser hair removal device with cosmetic functions, including a handle 1 that is approximately cylindrical in shape and a head 2 fixedly connected to one end of the handle 1, while the other end is provided with a power supply assembly 13. The head 2 is approximately cubic in shape and has a front cover 21 and a rear cover 22. A laser part 3 is located in the middle of the front cover 21. When using the laser hair removal device, the laser part 3 is brought into contact with the human skin and emits laser light. The laser part 3 includes a face cover 4 and a light outlet 5 located in the middle of the face cover 4. The light outlet 5 is rectangular in shape and penetrates through the face cover 4. In addition, the light outlet 5 is also provided with a light guide lens 51 adapted to it. The light guide lens 51 and... The device is in direct skin contact. The face cover 4 covers a circuit board 6 disposed inside the head 2. The circuit board 6 corresponds to the face cover 4, and the circuit board 6 is also hollowed out in the middle. The purpose of this structural design is not to affect the laser from passing through the light guide lens 51, while maintaining the normal operation of the device on the circuit board 6. The circuit board 6 is provided with several electrodes 61, several light therapy lamps 62, and a skin tone sensing device 63. The face cover 4 is also provided with a skin tone sensing port 41 corresponding to the skin tone sensing device 63. In other embodiments, the shape of the light outlet 5 can also be any shape, such as circular, triangular, or irregular, to achieve the same effect.

[0028] Most laser hair removal devices on the market only offer hair removal, making their functionality quite limited. However, market research indicates that people's demand for skin care is constantly increasing. Therefore, after using a laser hair removal device, users typically undergo further skin care, such as using beauty devices, to repair any damage caused by the laser treatment. This process requires a significant amount of time and effort, greatly reducing user convenience. To address this issue, the laser hair removal device with radio frequency beauty function incorporates several electrodes 61 and light therapy lamps 62 on the circuit board 6 of the laser unit 3. This allows users to simultaneously perform high-end beauty treatments such as whitening, skin rejuvenation, lifting, and cooling, promoting subcutaneous collagen regeneration, while removing hair. This maximizes the device's multi-functionality, enhances the consumer experience, increases the product's added value, and makes it more appealing to consumers, thus increasing customer loyalty.

[0029] Specifically, in one embodiment of this utility model, the working principle of the skin color sensing device 63 disposed on the circuit board 6 is as follows: based on the strong absorption of light by melanin, the skin color sensing device 63 determines the melanin content by emitting low-energy detection light and measuring the intensity of light reflected by the skin. Light-colored skin has less melanin, higher reflectivity, and a stronger signal returned by the detection light. Dark-colored skin has more melanin, absorbs more detection light, and has a weaker signal reflected. The working power of the laser is then adjusted based on the intensity of the received signal. The reason for this is that dark skin has too much melanin, which easily absorbs too much light and heat energy, thus causing damage to the skin. Therefore, the working power of the laser is adjusted to be smaller.

[0030] Specifically, in one embodiment of this utility model, the electrode 61 simultaneously outputs RF radio frequency and EMS microcurrent. The RF radio frequency has the following functions: stimulating collagen regeneration: generating heat energy through high-frequency current, acting on the dermis to promote the regeneration of collagen and elastin fibers, improving skin laxity and fine lines; tightening and lifting contours: the heat energy can tighten skin tissue, lift the jawline, reduce nasolabial folds, and make facial lines clearer; improving skin texture: promoting metabolism, helping the skin regain elasticity, brightening skin tone, and shrinking pores. The EMS microcurrent has the following functions: promoting blood circulation: current stimulation accelerates metabolism, helps the skin excrete waste, and brightens skin tone; enhancing the absorption of skincare products: opening skin channels and improving the penetration efficiency of nutrients such as essences; providing an immediate tightening effect: short-term use can quickly tighten the skin, suitable for emergency swelling reduction.

[0031] Furthermore, the face cover 4 is provided with a through hole 42 corresponding to the electrode 61. The electrode 61 passes through the face cover 4 through the through hole 42. This structural design allows the electrode 61, like the light guide lens 51, to directly contact human skin, enabling the RF radio frequency and EMS microcurrent functions of the electrode 61 to better act on the skin and improve the skin care effect. In other embodiments, the face cover 4 does not have a through hole, but directly covers the electrode 61.

[0032] Specifically, in one embodiment of this utility model, the face cover 4 is made of a light-transmitting material, and the light therapy lamp 62 is an LED lamp. The LED lamp can convert the emitted light energy into intracellular energy, accelerate the cell growth process cycle, stimulate fibroblasts to produce collagen, and will not cause any harm or discomfort to the skin. The semi-transparent face cover 4 also allows the light therapy lamp 62 to act on the human skin through the face cover 4. In other embodiments, the face cover 4 is made of a transparent material, which can also achieve the above-mentioned effects. In other embodiments, the light therapy lamp 62 can also be a fluorescent lamp, a halogen tungsten lamp, or an incandescent lamp, which can also achieve similar effects.

[0033] Specifically, in one embodiment of this utility model, on the circuit board 6, a plurality of electrodes 61 and phototherapy lamps 62 are evenly and alternately arranged around the light guide lens 51, wherein there are eight electrodes 61 and eight phototherapy lamps 62. This structural design makes the skin care effect of the electrodes 61 and phototherapy lamps 62 on human skin more uniform. In other embodiments, the electrodes 61 and phototherapy lamps 62 are arranged in two columns or other arbitrary arrangements on the circuit board 6, which can achieve the above effect. In other embodiments, the number of electrodes 61 and phototherapy lamps 62 can be arbitrarily set, which can also achieve the above effect.

[0034] Specifically, in one embodiment of this utility model, the light guide lens 51 is made of sapphire. Sapphire has strong thermal conductivity, so when the laser acts on human skin, the hair follicles absorb heat energy while the sapphire also absorbs heat energy from the human skin, preventing damage to the skin due to excessive temperature. At the same time, sapphire also has good light transmittance, allowing the laser to pass through the light guide lens 51 better with low energy loss. In addition, sapphire has high hardness, is wear-resistant and scratch-resistant, and is not easily worn or deformed after long-term use, ensuring stable light transmission performance. In another embodiment, the light guide lens 51 can also be made of glass, quartz, or plastic, achieving similar effects.

[0035] Specifically, in one embodiment of this utility model, the back cover 22 is provided with an indicator light 221. The indicator light 221 is elongated and can achieve different lighting lengths. The handle 1 is provided with a power assembly 13, including three operation buttons 12. These buttons are arranged in a single row longitudinally from the head 2 to the power assembly 13, namely the power button, the light-up button, and the beauty button. The indicator light 221 is composed of multiple LED beads 222 arranged longitudinally, which can achieve different continuous lighting lengths. When the light is white, the laser hair removal device is in working condition. The shorter the continuous lighting length of the indicator light 221 (fewer LED beads 222 lit continuously) indicates low output energy, and the longer the continuous lighting length of the indicator light 221 (more LED beads 222 lit continuously) indicates high output energy. When the light is red, the laser hair removal device is in a faulty or inoperable state.

[0036] Specifically, in one embodiment of this utility model, air inlets 11 are provided on both sides of the handle 1, and air outlets 23 are provided at the top of the head 2. This design can form a heat dissipation channel to dissipate heat from the internal device of the laser hair removal device, avoiding damage to the device due to excessive temperature. In another embodiment, the air outlets 23 can also be provided on the side of the head 2, which can achieve the same effect.

[0037] The working principle of this utility model is explained in detail below:

[0038] This laser hair removal device integrates hair removal and beauty functions through the coordinated operation of multiple modules. First, the skin tone sensing device 63 emits low-energy detection light to the skin surface. Based on the light absorption characteristics of melanin, it judges the user's skin tone in real time by the intensity of reflected light and automatically adjusts the laser output power to avoid thermal damage caused by excessively dark skin. The laser unit 3 precisely releases laser energy of a specific wavelength through the light guide lens 51, targeting the melanin in the hair follicle and destroying the hair follicle structure to achieve hair removal. At the same time, the electrodes 61, which are staggered around the light guide lens 51, contact the skin through the through-hole 42, simultaneously outputting RF radio frequency and EMS microcurrent: RF radio frequency generates high frequency... Thermal energy stimulates collagen regeneration in the dermis, improving skin laxity and fine lines; EMS microcurrent promotes blood circulation and metabolism, enhancing the absorption efficiency of skincare products and achieving an immediate firming effect. The phototherapy lamp 62 (such as an LED lamp) releases specific wavelength light energy through the translucent cover 4, accelerating cell repair and collagen synthesis, and alleviating skin sensitivity after hair removal. The device's built-in heat dissipation system forms a circulating air duct through the air inlet 11 of the handle 1 and the air outlet 23 of the head 2, ensuring stable operation of internal components for a long time. Users can select hair removal or beauty mode through the operation button 12, and the indicator light 221 provides real-time feedback on the working status, realizing intelligent, multifunctional, and one-stop care.

[0039] The innovations of this utility model are as follows: It effectively overcomes existing deficiencies through technological innovation, primarily manifested in: Functional integration: Integrating laser hair removal, radiofrequency tightening, microcurrent care, and phototherapy repair into one unit, achieving simultaneous hair removal and beauty enhancement, significantly improving efficiency and reducing user time and economic costs; Intelligent adaptability: Dynamically adjusting laser power based on skin tone sensing technology ensures safe use for users with different skin tones, greatly expanding the product's applicability; Synergistic effect: The synergistic effect of radiofrequency and microcurrent technologies promotes collagen regeneration and metabolic circulation, enhancing skin firmness and radiance, while the phototherapy module assists in repair, reducing post-hair removal skin irritation; Optimized stability: The heat dissipation system and modular design ensure long-term efficient operation of the device, avoiding overheating damage. These innovations make the product highly efficient, safe, and multifunctional, comprehensively improving user experience and market competitiveness.
