Description

Technical Field

[0001] The present application relates to the technical field of skin treatment, and particularly to a skin treatment device. Background Art

[0002] With the continuous progress of science and technology and the increasing demand for personal beauty care, skin treatment devices (such as hair removal devices) are high-tech products that integrate modern optical technology and personal care innovation. The light source component of the skin treatment device can emit light in a specific wavelength band, which can penetrate the epidermis of the skin and be accurately absorbed by the melanin inside the hair. As a natural light absorber, melanin will convert the absorbed light energy into heat energy after absorbing it. This energy conversion process directly targets and heats the hair follicles to destroy their regeneration ability, thereby effectively inhibiting hair regrowth.

[0003] The skin treatment device is provided with a skin sensor. The position of the skin sensor is generally set near the light outlet of the skin treatment device. The skin sensor can be used to directly or indirectly contact the user's skin, so that the skin treatment device can identify whether the skin is in contact with the sapphire through the skin sensor. The skin sensor can be electrically connected to the circuit board to transmit information about the contact situation between the skin sensor and the skin to the circuit board, thereby controlling the start and stop of the light source component.

[0004] However, the existing skin treatment device uses the housing as the sensing medium of the skin sensor, and the volume of the sapphire of the existing skin treatment device is designed to be larger and larger to increase the beauty efficiency of the skin treatment device. When the user's skin only contacts the sapphire of the skin treatment device, the skin treatment device fails to recognize the contact between the skin and the sapphire through the skin sensor located on the housing, resulting in the inability of the light source component of the skin treatment device to emit light. Summary of the Utility Model

[0005] An embodiment of the present utility model provides a skin treatment device to improve at least one of the above problems.

[0006] The embodiment of the present utility model realizes the above purpose through the following technical solutions.

[0007] The embodiment of the present utility model provides a skin treatment device, which includes a housing, a sensing medium, and a skin sensor. The housing is provided with a light source component. The sensing medium is made of crystal material.

[0010] In some embodiments, the housing includes a cavity for accommodating the light source assembly and / or the sensing medium. The housing has a side wall forming the cavity.

Wherein, the first sensing side faces the light source assembly, and the second sensing side is attached to the light incident surface; or, the first sensing side is attached to the side wall, and the second sensing side is attached to the connecting side surface.

[0011] In some embodiments, the sensing medium includes a light-transmitting main body and a mounting boss connected to each other. The mounting boss protrudes in the direction of the connecting side surface with respect to the light-transmitting main body. The skin sensing member is disposed between the housing and the light-transmitting main body; or, the skin sensing member is disposed between the housing and the mounting boss.

[0012] In some embodiments, the second sensing side is attached to the connecting side surface located on the light-transmitting main body or the connecting side surface located on the mounting boss.

[0013] In some embodiments, the skin sensing member is entirely located in the sensing medium and is attached to the light incident surface.

[0014] In some embodiments, the light exit surface of the sensing medium is flush with the surface of the housing; or, the light exit surface of the sensing medium protrudes from the surface of the housing.

[0015] In some embodiments, the skin sensing member is a flexible circuit board or a metal plating sensing member.

[0016] In some embodiments, the skin sensing member is arranged in a ring shape.

[0017] In some embodiments, the number of the skin sensing members is multiple, and the multiple skin sensing members are arranged at intervals in sequence along the edge of the sensing medium.

When the user's skin touches the sensing medium, the skin treatment device can recognize the contact between the skin and the sensing medium through the skin sensor, so that the skin treatment device can control the emitted light of the light source assembly to be emitted. In addition, when the skin fits with the sensing medium, the air gap between the skin surface and the sensing medium can be reduced, which helps to reduce the risk that the emitted light of the light source assembly is reflected or scattered into the air after passing through the sensing medium. Furthermore, more light energy of the light source assembly can reach the skin for treatment or care. Moreover, since the sensing medium is a crystal material and the crystal material has a high thermal conductivity, the sensing medium can quickly absorb the heat of the skin, so that the sensing medium has a cold compress effect on the skin, effectively reducing the temperature of the skin surface, and further helping to reduce the risk of the skin being burned during the phototherapy process.

Specific embodiments

[0037] In order to enable those skilled in the art to better understand the solution of the present utility model, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative efforts fall within the scope of protection of the utility model.

[0038] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the utility model.

[0039] Please refer to Figure 1 , an embodiment of the present utility model provides a skin treatment device 10. The skin treatment device 10 can be a hair removal device. The hair removal device can emit a series of intense pulsed light, which contains multiple wavelengths and can be absorbed by the melanin in the hair follicles. After the hair follicles absorb the light energy, the temperature of the hair follicles rises rapidly, resulting in damage to the hair follicle structure, thereby inhibiting or delaying hair regrowth. Alternatively, the skin treatment device 10 can be a beauty device. The beauty device can stimulate the skin to produce biological reactions, such as promoting the regeneration of collagen and elastic fibers, improving microcirculation, and enhancing the skin's self-repair ability. These reactions help improve the skin texture, enhance firmness and luster, and achieve the effect of skin rejuvenation.

[0040] Please refer to Figures 1 to 8 , the skin treatment device 10 can include a housing 100, a sensing medium 200, and a skin sensor 300. The housing 100 can be provided with a light source assembly 400. The sensing medium 200 can be made of crystal material. A part of the sensing medium 200 is exposed on the surface of the housing 100 and is used for the light emission of the light source assembly 400. At least a part of the skin sensor 300 is stacked with the sensing medium 200. Thus, compared with the skin treatment device 10 in the related art, in the skin treatment device 10 of the present application, at least a part of the skin sensor 300 is stacked with the crystal material sensing medium 200. When the user's skin touches the sensing medium 200, the skin treatment device 10 can recognize the contact between the skin and the sensing medium 200 through the skin sensor 300, so that the skin treatment device 10 can control the emitted light of the light source assembly 400 to be emitted.

[0041] In addition, when the skin fits with the sensing medium 200, the air gap between the skin surface and the sensing medium 200 can be reduced, which helps to reduce the risk that the emitted light of the light source assembly 400 is reflected or scattered into the air after passing through the sensing medium 200. Furthermore, more light energy of the light source assembly 400 can reach the skin for treatment or care. Moreover, since the sensing medium 200 is a crystal material and the crystal material has a high thermal conductivity, the sensing medium 200 can quickly absorb the heat of the skin, so that the sensing medium 200 has a cold compress effect on the skin, effectively reducing the temperature of the skin surface, and further helping to reduce the risk of the skin being burned during the phototherapy process.

[0042] It can be understood that the skin sensing component 300 can be in direct contact with the sensing medium 200, that is, the skin sensing component 300 is directly attached to the sensing medium 200; or, the skin sensing component 300 can be in indirect contact with the sensing medium 200, that is, the skin sensing component 300 is connected to the sensing medium 200 through a conductor.

[0043] There can be various choices for the sensing medium 200. For example, the sensing medium 200 can be sapphire; for another example, the sensing medium 200 can be peridot; for yet another example, the sensing medium 200 can be crystal, and specific selection can be made according to the actual situation.

[0044] There can be various ways for the skin treatment device 10 to recognize the contact between the skin and the sensing medium 200 through the skin sensing component 300. For example, the skin sensing component 300 can be a pressure sensor. When the skin contacts the sensing medium 200, the skin will slightly press the sensing medium 200, and the slight pressure generated by the skin contacting the sensing medium 200 will be captured by the skin sensing component 300. A deformable element (such as a strain gauge) can be provided inside the skin sensing component 300. When subjected to pressure, the deformable element will undergo a small deformation after being compressed, causing the resistance value of the deformable element to change. This change in resistance value can be converted into an electrical signal and transmitted to the circuit board of the skin treatment device 10, so that the skin treatment device 10 can recognize the contact between the skin and the sensing medium 200.

[0045] For another example, the skin sensing component 300 can be a photoelectric sensor. The sensing medium 200 can be provided with a light passing hole. The skin sensing component 300 can include a transmitter and a receiver. The transmitter and the receiver can be arranged on the same side of the light passing hole. The transmitter can emit light through the light hole. When the skin contacts the sensing medium 200, the skin can block the light passing hole. At this time, the light emitted by the transmitter can be reflected by the skin and received by the receiver. After the receiver receives the light, it can be converted into an electrical signal and transmitted to the circuit board of the skin treatment device 10, so that the skin treatment device 10 can recognize the contact between the skin and the sensing medium 200.

[0046] For another example, the skin sensing component 300 can be a capacitive sensor. When the skin is not in contact with the sensing medium 200, the skin sensing component 300 can serve as a reference capacitor, and at this time, the total capacitance value of the capacitance circuit of the skin sensing component 300 is the value of the reference capacitor; when the skin is in contact with the sensing medium 200, the skin sensing component 300 can serve as a reference capacitor, the skin can serve as one plate of the capacitor, and the sensing medium 200 made of crystal material can serve as the insulating medium of the capacitor, so that one of the substrates of the skin, the sensing medium 200, and the skin sensing component 300 forms an identification capacitor. The identification capacitor is connected in parallel with the reference capacitor. At this time, the total capacitance value of the capacitance circuit of the skin sensing component 300 is the sum of the value of the identification capacitor and the value of the reference capacitor. And the skin sensing component 300 is electrically connected to the circuit board, and the circuit board can determine whether the skin is in contact with the sensing medium 200 according to the size of the total capacitance value of the capacitance circuit of the skin sensing component 300, so that the skin processing device 10 can recognize that the skin is in contact with the sensing medium 200.

[0047] In the following embodiments, the skin sensing component 300 is mainly taken as an example of a capacitive sensor for description. The embodiments in which the skin sensing component 300 is used as other sensors can be referred to for implementation.

[0048] Please refer to Figure 7 and Figure 15 In some embodiments, a part of the skin sensing component 300 is stacked with the sensing medium 200, and another part of the skin sensing component 300 is stacked with the housing 100. Specifically, for example, when the user's skin touches the sensing medium 200, the sensing medium 200 can serve as an insulating medium, and the skin sensing component 300, the sensing medium 200, and the user's skin can form an identification capacitor, causing the total capacitance value of the capacitance circuit of the skin sensing component 300 to change, which helps the skin processing device 10 recognize the contact between the sensing medium 200 and the user's skin through the skin sensing component 300, thereby helping to control the light of the light source component 400 to be emitted to the sensing medium 200; for another example, when the user's skin touches the housing 100, the housing 100 serves as an insulating medium, and the skin sensing component 300, the housing 100, and the user's skin can form an identification capacitor, causing the total capacitance value of the capacitance circuit of the skin sensing component 300 to change, which helps the skin sensing component 300 recognize the contact between the housing 100 and the user's skin through the skin sensing component 300, thereby helping to control the light of the light source component 400 to be emitted to the sensing medium 200. In this way, the skin sensing component 300 can be stacked with both the sensing medium 200 and the housing 100, which helps the skin processing device 10 sense the user's skin in a relatively wide area, thereby helping to improve the overall sensing sensitivity of the skin processing device 10.

[0049] In addition, the user can directly touch the housing 100 or the sensing medium 200, both of which can trigger the light source assembly 400 to emit light, so that the user does not need to pay special attention to the position of skin contact during use, which helps to reduce the operation burden of the user, and thus helps to improve the convenience of the skin treatment device 10 during the treatment process.

[0050] Moreover, the skin treatment device 10 realizes double detection of the contact between the sensing medium 200 and the housing 100 through a single skin sensor 300, which helps to increase the area where the skin treatment device 10 senses the skin through the skin sensor 300, so that the skin treatment device 10 can accurately sense the skin, and further helps to reduce the risk of missed light emission of the skin treatment device 10.

[0051] It can be understood that the skin sensor can be in direct contact with the housing 100. For example, the skin sensor 300 is directly attached to the housing 100; or, the skin sensor 300 can be in indirect contact with the housing 100. For example, the skin sensor 300 is in contact with the housing 100 through a conductor.

[0052] Please refer to Figures 3 to 15 , in some embodiments, the sensing medium 200 can be sapphire. The sensing medium 200 can be arranged in a plate shape. The sensing medium 200 can be provided with a light incident surface 210, a light exit surface 220 and a connecting side surface 230. The light exit surface 220 can be used to contact the skin. The light emitted by the light source assembly 400 can pass through the light incident surface 210 and the light exit surface 220 in sequence. The connecting side surface 230 can be connected between the light incident surface 210 and the light exit surface 220. At least part of the skin sensor 300 is attached to the connecting side surface 230 and / or the light incident surface 210. In this way, the skin sensor 300 does not directly contact the user's skin, but is attached to the connecting side surface 230 and / or the light incident surface 210 of the sensing medium 200, which helps to avoid direct electrical contact between the skin sensor 300 and the human body, and thus helps to reduce the risk of electric shock accidents when the user uses the skin treatment device 10, and thus helps to improve the electrical safety performance during the use of the skin treatment device 10.

[0053] In addition, the skin sensor 300 is not directly exposed on the light exit surface 220, so that the skin sensor 300 does not directly rub against the user's skin frequently, which helps to reduce the wear and pollution of the skin sensor 300, and thus helps to extend the service life of the skin sensor 300, and at the same time helps to maintain the sensitivity and accuracy of the skin sensor 300 so that the skin sensor 300 can work stably.

[0054] Moreover, since the skin sensor 300 does not directly contact the skin, the accumulation of dirt and grease on the skin sensor 300 is reduced, which helps the user to clean and maintain the skin treatment device 10.

[0055] In some embodiments, the housing 100 may include a cavity 110 for accommodating the light source assembly 400 and / or the sensing medium 200. The housing 100 may have a side wall 120 forming the cavity 110. The overall outer contour of the skin sensor 300 may be generally flat. The skin sensor 300 may have a first sensing side 310 and a second sensing side 320 facing away from each other in the thickness direction.

[0056] In some embodiments, as Figure 15 shown, the first sensing side 310 may be arranged facing the light source assembly 400, and the second sensing side 320 may be in contact with the light incident surface 210. When the skin contacts the sensing medium 200, the skin may serve as one capacitor plate, the sensing medium 200 may serve as the insulating medium of the capacitor, and the second sensing side 320 may serve as the other capacitor plate, so that the skin, the sensing medium 200, and the second sensing side 320 can form a recognition capacitor, causing the total capacitance value of the capacitance circuit of the skin sensor 300 to change, thereby helping the skin treatment device 10 to recognize the contact between the user's skin and the sensing medium 200 through the skin sensor 300, and further helping the skin treatment device 10 to control the light source assembly 400 to emit light.

[0057] In some embodiments, as Figure 8 shown, the first sensing side 310 may be arranged facing the light source assembly 400, and the second sensing side 320 may be in contact with the light incident surface 210 and the side wall 120. When the skin contacts the sensing medium 200 and / or the housing 100, the sensing medium 200 and / or the housing 100 may serve as the insulating medium of the capacitor, the skin serves as one capacitor plate, and the second sensing side 320 serves as the other capacitor plate to form a recognition capacitor, causing the total capacitance value of the capacitance circuit of the skin sensor 300 to change, thereby helping the skin treatment device 10 to recognize the contact between the user's skin and the sensing medium 200 through the skin sensor 300, and further helping the skin treatment device 10 to control the light source assembly 400 to emit light.

[0058] In some embodiments, as Figure 10 、 Figure 11 and Figure 13As shown, the first sensing side 310 can be attached to the side wall 120, and the second sensing side 320 can be attached to the connecting side surface 230; when the user's skin touches the housing 100, the skin, the housing 100, and the first sensing side 310 can form a recognition capacitance; and / or, when the user's skin touches the sensing medium 200, the skin, the housing 100, and the second sensing side 320 can also form a recognition capacitance, so that the total capacitance value of the capacitance circuit of the skin sensing member 300 changes, which helps the skin processing device 10 to recognize the contact between the user's skin and the sensing medium 200 and / or the housing 100 through the skin sensing member 300, and further helps the skin processing device 10 to control the light source assembly 400 to emit light.

[0059] Please refer to Figure 3 、 Figure 4 、 Figure 10 and Figure 11 , in some embodiments, the sensing medium 200 may include a connected light-transmitting main body 240 and a mounting boss 250. The mounting boss 250 protrudes in the direction of the connecting side surface 230 relative to the light-transmitting main body 240, and the skin sensing member 300 may be disposed between the housing 100 and the light-transmitting main body 240; or, the skin sensing member 300 may be disposed between the housing 100 and the mounting boss 250. Thus, the sensing medium 200 and the housing 100 can clamp and fix the skin sensing member 300, which helps the skin sensing member 300 to be stably mounted between the sensing medium 200 and the housing 100, so that the skin sensing member 300 can work properly. In addition, it also enables the first sensing side 310 to be directly attached to the side wall 120, and the second sensing side 320 to be directly attached to the connecting side surface 230.

[0060] In some embodiments, as Figure 10 and Figure 11 shown, the second sensing side 320 is attached to the connecting side surface 230 of the light-transmitting main body 240 or the connecting side surface 230 of the mounting boss 250. Thus, the skin sensing member 300 is attached to the connecting side surface 230 of the light-transmitting main body 240 or the connecting side surface 230 of the mounting boss 250, so as to avoid the skin sensing member 300 from blocking the light incident surface 210, and further helps to reduce the risk of the skin sensing member 300 blocking the outgoing light of the light source assembly 400.

[0061] Please refer to Figure 14 and Figure 15, in some embodiments, the skin sensor 300 can be entirely located within the sensing medium 200 and adhered to the light incident surface 210. In this way, only when the skin is in direct contact with the sensing medium 200 can the skin treatment device 10 recognize the contact between the skin and the sensing medium 200 through the skin sensor 300, thereby triggering the light source assembly 400 to operate. This helps to improve the targeting and accuracy of the treatment of the skin treatment device 10, and enables the effective utilization of the light energy of the light source assembly 400, reducing resource waste.

[0062] In some embodiments, the light exit surface 220 of the sensing medium 200 can be flush with the surface of the housing 100, so that the surface of the skin treatment device 10 is flat, which in turn helps the user's skin to come into contact with the sensing medium 200 quickly and fully.

[0063] In some embodiments, the light exit surface 220 of the sensing medium 200 protrudes from the surface of the housing 100, that is, the light exit surface 220 of the sensing medium 200 extends beyond and is higher than the surface of the housing 100, so that the user's skin can come into contact with the sensing medium 200 first. In addition, the protruding sensing medium 200 acts as a natural guiding device, enabling the user to quickly bring the skin into contact with the sensing medium 200.

[0064] In some embodiments, the skin sensor 300 can be a flexible circuit board. The flexible circuit board is composed of an insulating substrate with high flexibility (such as a polyimide film) and conductive paths formed thereon, and can be designed into any shape to adapt to the complex structure inside the device. Specifically, the flexible circuit board is precisely cut and shaped so that it can conform to specific areas such as the light incident surface 210, the connecting side surface 230 of the sensing medium 200 of the skin treatment device 10, and even the inner side wall 120 of the housing 100, ensuring accurate sensing even in the curved surface or narrow space of the skin treatment device 10.

[0065] In addition, the flexible circuit board has good bend resistance, enabling the skin sensor 300 to be better adhered and installed to the housing 100 and / or the sensing medium 200. Moreover, the thin and light characteristics of the flexible circuit board reduce the overall weight and volume of the skin treatment device 10, making the user feel more lightweight and comfortable when holding or operating the skin treatment device 10.

[0066] In some embodiments, the skin sensor 300 can be a metal-coated sensor. Among them, the metal-coated sensor can include a first metal coating, an insulating medium, and a second metal coating. The insulating medium can be located between the first metal coating and the second metal coating, so that the metal-coated sensor can be used as a reference capacitor. Among them, the first metal coating and the second metal coating can be a thin and uniform metal film (such as copper, silver, gold, etc.) formed on the key contact surfaces of the sensing medium 200, the housing 100 or its internal structure of the device through processes such as physical vapor deposition (PVD), chemical vapor deposition (CVD), or electroplating.

[0067] In addition, the metal-coated sensor has strong anti-wear and anti-oxidation capabilities. Even after long-term use, it can maintain good sensing performance, extending the service life and maintenance cycle of the skin treatment device 10.

[0068] Moreover, the first metal coating or the second metal coating can be directly plated on the key parts of the device without additional installation components, simplifying the internal structure of the skin treatment device 10, reducing the assembly steps of the skin treatment device 10, facilitating the reduction of the volume of the skin treatment device 10, and improving the compactness and aesthetics of the skin treatment device 10.

[0069] In some embodiments, the skin sensor 300 can be arranged in a ring shape. In this way, the ring-shaped skin sensor 300 can increase the sensing range of 360 degrees, enabling the user's skin to be quickly recognized no matter which direction or angle it contacts the skin treatment device 10, thus helping to improve the convenience performance of the skin treatment device 10 during use. In addition, the skin sensor 300 being arranged in a ring shape helps to reduce the strict requirements for the skin contact position of the user on the skin treatment device 10, making the user more free when using the skin treatment device 10 without having to deliberately find a contact point at a specific angle.

[0070] In some embodiments, the number of skin sensors 300 is multiple, and the multiple skin sensors 300 can be arranged at intervals in sequence along the edge of the sensing medium 200. In this way, the multiple skin sensors 300 are arranged at intervals along the edge of the sensing medium 200. Even if one or several skin sensors 300 are damaged or fail due to reasons, the remaining skin sensors 300 can still work normally, ensuring that the skin treatment device 10 can continue to accurately sense skin contact, thus helping to reduce the risk of the overall function of the skin treatment device 10 being lost due to a single failure point, and further helping to improve the stability and reliability of the skin treatment device 10.

[0071] In some embodiments, the light source assembly 400 can include an LED lamp tube; or, the light source assembly 400 can include an IPL lamp tube, which can be specifically selected according to the actual situation.

[0072] In a utility model, unless otherwise clearly specified or defined, terms such as "installation" and "connection" shall be understood in a broad sense.
