Description

Technical Field

[0001] This utility model belongs to the field of hair removal devices, specifically relating to a laser hair removal device with a magnetic wireless sensing attachment head. Background Technology

[0002] Photothermal hair removal is based on the principle of selective photothermolysis. It utilizes the "selective photothermal effect" of light, using light tuned to a specific wavelength to penetrate the epidermis and directly target the hair follicle. The melanin in the hair follicle and hair shaft selectively absorbs the light energy, and the resulting thermal effect causes the hair follicle to die, preventing hair regrowth. As a safe, fast, and long-lasting hair removal technology, photothermal hair removal is increasingly favored by consumers. However, traditional hair removal devices lack safety mechanisms, which can lead to accidental exposure of the user's eyes while the device is in operation, causing discomfort and reducing the user experience.

Detailed Implementation

[0034] 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.

[0035] like Figures 1-14 As shown, this utility model provides a laser hair removal device with a magnetically attached wireless sensing accessory head, including a handle 1 and a working part 2 disposed on the top of the handle 1. The handle 1 contains a main control 11 and a power switch 12. The working part 2 has a working surface 21 on one side, with a light emission port 220 in the center of the working surface 21. The inner side of the working surface 21 is provided with a heat dissipation component 22, a light emission component 23, and a sensing component 24. The sensing component 24 includes at least a capacitive sensor 242, which is made of copper or aluminum foil. The heat dissipation component 22 is used to dissipate heat from the light emission component 23 and includes at least a cooling fan 20. Figure 1As shown, during use, the operator presses the power button 12 and then places the working surface 21 of the working part 2 against the user's skin. The capacitance value of the capacitive sensor 242 changes, thereby identifying the contact state. The main controller 11 controls the light-emitting component 23 to emit light, and the light passes through the light emission port 220 to irradiate the user's skin surface for hair removal.

[0036] Based on this, such as Figure 2 As shown, an auxiliary head 3 is also provided, which is magnetically connected to the working surface 21. The auxiliary head 3 is beak-shaped and includes a contact surface 301 and a mating surface 302. The area of ​​the contact surface 301 is smaller than the area of ​​the mating surface 302, and the area of ​​the mating surface 302 is equal to or greater than the area of ​​the working surface 21. The working surface 21, the mating surface 302, and the contact surface 301 are all continuous and smooth planes or curved surfaces. A light outlet 30 is provided between the contact surface 301 and the mating surface 302. A sensing plate 32 is provided inside the auxiliary head 3. The sensing plate 32 extends from the mating surface 302 to the corresponding inner surface of the contact surface 301, and is combined with... Figure 14 As shown, the sensing sheet 32 ​​includes a sensing foot 321 and a sensing ring 322. The sensing ring 322 surrounds the light outlet 30 and is attached to the inner surface corresponding to the contact surface 301. The material of the sensing sheet 32 ​​is a copper foil or an aluminum foil. The area of ​​the light outlet 30 is smaller than the area of ​​the light emitting port 220. In use, the mating surface 302 of the auxiliary head 3 is magnetically mated with the working surface 21 of the working part 2. By pressing the power button 12 and then attaching the contact surface 301 of the auxiliary head 3 to the user's skin, when the contact surface 301 of the auxiliary head 3 is attached to the user's skin, the sensing sheet 32 ​​in the auxiliary head 3 can extend the sensing range of the capacitive sensing element 242, thereby causing a change in the capacitance value of the capacitive sensing element 242 to identify the contact state. The main controller 11 controls the light-emitting component 23 to emit light, and the light passes through the light outlet 30 of the auxiliary head 3 and shines on the surface of the user's skin. Hair removal is performed using the above solutions. The operation involves pressing the power button 12, and then the laser hair removal device, via the magnetic wireless sensor attachment, contacts the user's skin. This causes a change in the capacitance value of the capacitive sensor, achieving a recognition effect. Only then can the main controller control the light-emitting component to perform luminous hair removal. Furthermore, the capacitive sensor 242 is basically parallel to the working surface 21 and its shape is adapted to its distribution, and the sensor plate 32 is set to fit against the contact surface 301. The product will only activate its laser function when it senses a capacitance value exceeding a preset threshold, thus improving safety and enhancing user comfort.

[0037] Furthermore, such as Figures 6-12As shown, a cover plate 33 is provided on one side of the mating surface 302 of the auxiliary head 3. The cover plate 33 is integrally formed of conductive metal or plastic molded with conductive metal material attached to one side of the mating surface 302. The cover plate 33 and the inner wall of the auxiliary head 3 form a cavity 331. A reflector cup 34 made of mirror aluminum material is provided in the cavity 331. The reflector cup 34 is open at both ends, and the reflective surface of the reflector cup 34 forms part of the inner surface of the light outlet 30. A second filter 330 is provided between the cover plate 33 and the reflector cup 34. There are two fixed magnets 311 symmetrically inside the auxiliary head 3. Two magnetic attractors 210 are provided on the inner side of the working surface 21 corresponding to the two fixed magnets 311. The capacitive sensing element 242 is arranged in a closed-circuit ring along the working surface 21. The capacitive sensing element 242 forms clearance positions 240 around each of the magnetic attractors 210. The sensing sheet 32 ​​is attached to the inner side of the auxiliary head 3 and is conductive to the cover plate 33. The sensing component 24 also includes a Hall sensor 243, and two diagonally symmetrically distributed sensing magnets 31 are disposed within the auxiliary head 3 corresponding to the Hall sensor 243. Specifically, as Figure 7 , Figure 10 , Figure 12 As shown, when the auxiliary head 3 is magnetically connected to one side of the working surface 21 of the working part 2, the magnetic connection between the auxiliary head 3 and the working surface 21 of the working part 2 is achieved by magnetically connecting the fixed magnet 311 to the working surface 21 of the working part 2. This can be accomplished by simultaneously providing magnetically engaging components 210 on the inner side of the working surface 21, allowing the fixed magnet 311 in the auxiliary head 3 and the magnetically engaging components 210 in the working surface 21 to magnetically engage with each other, thus achieving the magnetic connection between the auxiliary head 3 and the working surface 21. Alternatively, the working surface 21 can be made of a magnetic material; for example... Figure 12 As shown, in order to balance the stability of the magnetic attraction structure and the effective use of space, the magnetic attraction components 210 are symmetrically arranged on both sides of the working surface 21. The capacitive sensing component 242 surrounds the outer side of the magnetic attraction component 210 to form a clearance 240. By setting the clearance 240, it can bypass the magnetic attraction component 210, thereby avoiding the situation where the capacitive sensing component 242 covers one or the other side of the magnetic attraction component 210 near the working surface 21, thus avoiding affecting the sensing effect of the capacitive sensing component 242 and reducing the overall thickness of the working part 2; Figure 7 , Figure 10 , Figure 12As shown, a sensing magnet 31 is also provided to magnetically sense the Hall sensor 243. After the mating surface 302 of the auxiliary head 3 is installed on the working surface 21, the sensing magnet 31 magnetically senses the Hall sensor 243. At this time, the main controller 11 receives a signal that the auxiliary head 3 has been installed on the working surface 21. The sensing range of the capacitive sensing element 242 is expanded through the sensing plate 32 in the auxiliary head 3. In use, the capacitive sensing element 242 senses the change in capacitance value of the sensing plate 32. At least two sensing magnets 31 can be provided. When there are two sensing magnets 31, the two sensing magnets 31 can be centrally symmetrical about the center of the metal cover plate 33. For example, in some embodiments, such as Figures 6-11 As shown, the auxiliary head 3 is beak-shaped. The smaller side of the auxiliary head 3 is the contact surface 301 that contacts the user's skin, and the larger side is the mating surface 302 that contacts the working surface 21. The outer edges of the contact surface 301 and the mating surface 302 are connected by an inclined transition surface. The sensing plate 32 is disposed inside the auxiliary head 3 on the side corresponding to the contact surface 301, extending the sensing distance of the capacitive sensing element 242. The light emission port 30 penetrates the mating surface 302 of the auxiliary head 3, and the contact surface 301 opens outward. The inner wall of the light emission port 31 is used for the mounting groove of the reflector cup 34. The mounting groove is a structure that extends from the contact surface 301 to the mating surface 302, and the shape of the light emission port 31 corresponds to the shape of the reflector cup 34. The shape of the light emission port 31 can be a rectangular structure or a square structure. It can also be any other shape or structure. A second filter 330 is fixed to one end of the reflector cup 34 located on the mating surface 302. The second filter 330 is sandwiched between the inner side of the cover plate 33 and the reflector cup 34. In this case, two induction magnets 31 are respectively placed at corresponding positions on opposite corners of the cover plate 33 and the reflector cup 34, allowing the auxiliary head 3 to be installed on the working surface 21 in any direction, regardless of its vertical orientation. After installation, the Hall sensor 243 can magnetically sense each induction magnet 31. After the light-emitting component 23 emits light, to avoid brightness loss when passing through the light outlet 30, the reflector cup 34 is used to reflect light that was originally emitted in other directions, reducing brightness loss and achieving better illumination. Figure 7 , Figure 8 , Figure 10 , Figure 11 As shown, two sets of sensor sheets 32 can be set. The two sensor sheets 32 are symmetrically arranged on both sides of the reflector cup 34. Both ends of the two sensor sheets 32 are attached to the side of the auxiliary head 3 located in the cavity 331 and extend towards the cover plate 33, and are connected to the cover plate 33 to achieve better sensing cooperation with the capacitive sensing element 242.

[0038] Furthermore, such as Figure 1 , Figure 2 , Figure 3 , Figure 13 As shown, the working part 2 is also provided with a fixing groove 5, which runs vertically through the working part 2 and opens towards the working surface 21. The light-emitting component 23 is fixed to the inner wall of the fixing groove 5. The cooling fan 20 is located at the bottom of the working part 2 and is used to supply external air to the fixing groove 5 and the cooling component 22 for heat dissipation. A reflector 51 is provided in the fixing groove 5. The reflector 51 is tile-shaped and parallel to the vertical direction of the fixing groove 5, reflecting the light from the light-emitting component 23 towards the working surface. The handle 1 has several air inlets 10 on its side and several air outlets 101 on the top of the working part 2. When the cooling fan 20 is started, air flows upward from the air inlets 10 on the side of the handle 1 and is blown out through the air outlets 101 on the top of the working part 2. At least some air is blown out from the bottom of the fixing groove 5 to the top of the fixing groove 5. Specifically, as Figures 1-3 As shown, the handle 1 is connected to the working part 2, and the side of the handle 1 is provided with several air inlets 10, while the top of the working part 2 is provided with several air outlets 101. When the cooling fan 20 is started, as... Figure 4 , 5 As shown, air flows upward from the air inlet 10 on the side of the handle 1 and is blown out through the air outlet 101 at the top of the working part 2. During the airflow, it passes through the fixing groove 5 and is blown out from the bottom to the top of the fixing groove 5, thereby dissipating heat from the light-emitting component 23 in the fixing groove 5. Simultaneously, as... Figure 13 As shown, by setting a reflector 51 arranged vertically in a tile shape, it is possible to ensure that the light emitted by the light-emitting component 23 is reflected by the reflector 51 and enters the working surface 21, and is then illuminated through the light outlet 30 of the auxiliary head 3. It also ensures that air can enter the reflector 51 to dissipate heat from the light-emitting component 23 and the reflector 51. Simultaneously, the air flowing through the heat dissipation component 22 dissipates heat from the heat dissipation component 22, achieving a heat dissipation effect on the sapphire lens 232. It is worth noting that the main controller 11 inside the handle is also connected to a capacitor connected to the power supply. In some embodiments, such as... Figure 13 As shown, the reflector 51 has a reflective groove that encloses all the light-emitting tubes 233 and reflects the light emitted by all the light-emitting tubes 233 to the sapphire lens 232. In other embodiments, the reflector 51 has multiple reflective grooves corresponding to each light-emitting tube 233, and each reflective groove individually reflects the light emitted by the corresponding light-emitting tube 233 to the sapphire lens 232 to achieve a reflection effect.

[0039] Furthermore, such as Figure 1 , Figure 2 , Figure 4 , Figure 5As shown, the light-emitting component 23 includes a light-emitting tube 233, a sapphire lens 232, and a first filter 234. The working part 2 is provided with a fixing member 231 for fixing the sapphire lens 232. The sapphire lens 232 is installed inside the light-emitting port 220. The exposed surface of the sapphire lens 232 is flush with the working surface 21, allowing both to simultaneously contact the skin. Figure 4 As shown, a sealing sleeve 235 is provided between the sapphire lens 232 and the first filter 234 to form a closed gap 236, thereby preventing external air from entering the gap 236 and condensing and adhering to the sapphire lens 232 and the first filter 234. Figure 4 , 5 As shown, the heat dissipation assembly 22 includes a plurality of fins 221 and heat dissipation copper pipes 222 connected to each of the fins 221. One side of the heat dissipation copper pipe 222 extends and fits against one side of the sapphire lens 232. Specifically, as Figure 4 , 5 As shown, light is emitted through the light-emitting tube 233, and the light is reflected by the reflector 51, causing the light to pass sequentially through the first filter 234, the gap 236, the sapphire lens 232, and the second filter 330, enter the reflector cup 34, and be illuminated through the light outlet 30; as shown Figure 4 , 5 As shown, the sapphire lens 232 heats up after being illuminated by the light-emitting diode 233. By attaching the end of the heat dissipation copper pipe 222 to the side of the sapphire lens 232, heat can be dissipated and cooled, facilitating rapid cooling and preventing burns to the user. The heat dissipation copper pipe 222 conducts heat to each fin 221, which is then cooled by the cooling fan 20, achieving a good heat dissipation effect. Thermal grease can be applied to the side of the heat dissipation copper pipe 222 where it is attached to the sapphire lens 232 to enhance thermal conductivity. Additionally, the second filter 330 is also simultaneously disposed on the side of the reflector 34 near the light-emitting component 23 to achieve a better filtering effect. Figure 1 As shown, in some other embodiments, when the auxiliary head 3 is not used, the working surface 21 is directly attached to the user's skin surface, and large-area hair removal is performed on the user's skin surface through the light emission port 220. After the working surface 21 is attached to the user's skin surface, the capacitance value of the capacitive sensor 242 changes, thereby identifying the attachment state. At this time, the heat dissipation copper pipe 222 transfers the heat of the sapphire lens 232 to the fins 221. The cooling fan 20 draws air in through the air inlet 10 and blows it onto the fins 221 to cool the fins 221. The heated air is blown out from the air outlet 101, achieving a cooling effect on the sapphire lens 232. During the hair removal process, the sapphire lens 232 is attached to the user's skin, and the sapphire lens 232 can be used to apply a cold compress to the hair removal area of ​​the user's skin, improving user comfort. At the same time, as Figure 1 , Figure 12 As shown, when the light emitted by the LED bead 2440 shines on the user's skin, it is reflected and captured by the light reflection sensor 244. The intensity of the reflection varies depending on the user's skin tone. When the user's skin tone is lighter, more light is reflected. After sensing this through the light reflection sensor 244, the main control 11 controls the increase of the light emission power of the light-emitting component 23. When the user's skin tone is darker, less light is reflected. After sensing this through the light reflection sensor 244, the main control 11 controls the decrease of the light emission power of the light-emitting component 23 to prevent users with darker skin tones from being burned.

[0040] The following is a detailed explanation of the working principle of this utility model;

[0041] In use, the auxiliary head 3 is placed on one side of the working surface 21 of the working part 2 and magnetically connected to the working surface 21. By pressing the power switch 12 and then placing the auxiliary head 3 against the user's skin, the sensing range of the capacitive sensor 242 can be extended through the sensing plate 32 inside the auxiliary head 3, thereby causing a change in the capacitance value of the capacitive sensor 242 to identify the contact state. The main controller 11 controls the light-emitting component 23 to emit light, and the light passes through the light outlet of the auxiliary head 3 to illuminate the user's skin surface for hair removal. Alternatively, by pressing the power switch 12 and then placing the working surface 21 of the working part 2 against the user's skin, the capacitance value of the capacitive sensor 242 changes to identify the contact state, and the main controller 11 controls the light-emitting component 23 to emit light, and the light passes through the light emission port 220 to illuminate the user's skin surface for hair removal. This improves the safety of use, avoids abnormal light emission to the user, and enhances the user's comfort.
