Description

Integrated conductive surface EMS beauty device Technical Field

[0001] This application relates to the field of beauty and skin care equipment technology, and in particular to an EMS beauty device. Background Technology

[0002] Currently available radio frequency (RF) or EMS beauty devices use either metal RF electrodes or plastic electroplated electrodes. This method is relatively simple and cannot achieve large-area conductivity, resulting in ineffective treatment areas. Furthermore, it cannot be effectively combined with phototherapy methods because the opaque electrodes prevent the light source from penetrating the skin for heating when they overlap, hindering the seamless integration of light and electricity and preventing the maximization of photothermal effects. In addition, the electroplated electrode areas are not smooth, hindering the simplification and flatness of the overall structure. When applied to actual products, this fails to meet users' requirements for contact smoothness and adherence, reducing the effectiveness of skin rejuvenation. Applying gel during use can easily lead to dirt buildup, which is difficult to clean and can contaminate the skin. This structure also has poor waterproofing and sealing properties.

[0003] Therefore, it is necessary to provide an EMS beauty device that can better fit the human body, has a good contact effect, is easy to clean, and has good waterproof performance. Technical issues

[0004] The purpose of this application is to provide an integrated conductive EMS beauty device that can better fit the human body and has a better contact effect. Technical solutions

The EMS component and the conductive element are electrically connected to the electronic control board. The conductive element includes a crystal with a contact surface and a conductive film disposed on the contact surface of the crystal. The conductive element is disposed at the contact end of the beauty device that contacts the human body. The electronic control board controls the conductive element to generate an EMS current that acts on the human body.

[0007] This application utilizes a conductive component combining the crystal and conductive film to achieve an integrated conductive surface, eliminating the need for separately fabricated metal or plastic electroplated electrode points. This conductive component serves as the contact end between the beauty device and the skin, with no electrode point steps or gaps on its surface. When in contact with the skin, it can adhere well without any scratchy feeling, making the surface feel more comfortable. Furthermore, due to the use of an integrated contact end without electrode point gaps, no dirt will be generated when applying gel to its surface, resulting in better waterproof and gel-proof sealing effects and easier cleaning.

A central void in the ring-shaped semiconductor cooling element allows light waves to pass through. Alternatively, the beauty device includes one or more semiconductor cooling elements attached to one or more sides of the conductive element to cool the sides of the conductive element. Specifically, the hot side of the semiconductor cooling element can be one or a combination of several of the following: a heat pipe, a vapor chamber, a superheatable heat pipe, a superheatable heat plate, or a thermally conductive substrate made of a single thermally conductive material.

[0038] Please refer to Figure 1. Embodiment 1 of the integrated conductive surface EMS beauty device of this application includes an electronic control board 901, an EMS component (not shown), and a conductive element 100. The EMS component is disposed on the electronic control board 901 and connected to the main control board control module. The EMS component and the conductive element 100 are connected. The conductive element 100 includes a crystal (not shown) with a contact surface and a conductive film (not shown) disposed on the contact surface of the crystal.

[0039] EMS (Electrical Muscle Stimulation) is a technology that uses electrical pulses to stimulate muscle movement. Essentially, it's a pulse signal that simulates the body's bioelectricity to stimulate subcutaneous muscle movement. EMS microcurrents can significantly increase the expression of collagen and elastin, effectively promoting collagen production and thus improving skin firmness and elasticity. This process not only helps improve muscle definition but also achieves a remarkable lifting effect on facial contours, like giving your skin a "yoga" treatment. It tightens loose muscles, makes contours clearer and more defined, and diminishes fine lines and wrinkles imperceptibly, leaving skin rejuvenated. EMS microcurrents also promote lymphatic circulation, helping to reduce eye puffiness and dark circles, with significant effects for those who frequently stay up late or are prone to eye puffiness. Combined with other technologies such as RF radio frequency and phototherapy, EMS beauty devices can also address various skin problems, such as fading acne scars, shrinking pores, whitening, moisturizing, and fading dark spots.

[0040] The beauty device also includes a housing, within which the electronic control board 901 and the EMS assembly are housed. The housing includes a main shell 902, a front shell 903, and a rear shell 904. The front shell 903 is located at the front end of the main shell 902 and forms an opening 905. A conductive element 100 is disposed at the opening 905, forming the contact end of the beauty device, which can be used for contact with human skin, or, in some embodiments with phototherapy effects, for irradiating human skin. The conductive element 100 is located at the contact end where the beauty device contacts the human body, and the electronic control board 901 controls the conductive element 100 to generate an EMS current that acts on the human body.

[0041] This application uses a conductive component 100 that combines the crystal and the conductive film to achieve an integrated conductive surface, eliminating the need to separately manufacture metal or plastic electroplated electrode points. This conductive component 100 serves as the contact end between the beauty device and the skin. Its surface has no electrode point steps or gaps, allowing it to fit well with the skin surface without any scratchy feeling, making the surface feel more comfortable. Furthermore, because it uses an integrated contact end without electrode point gaps, no dirt will be generated when applying gel to its surface, resulting in better waterproof and anti-gel sealing effects and easier cleaning.

[0042] In a specific embodiment, the crystal with the contact surface is a translucent or transparent crystal, and the conductive film is an ITO transparent conductive film. The crystal and the translucent conductive film together form the light-transmitting conductive component 100. When using the optically transparent conductive component 100, it can be combined with a phototherapy component in a beauty device to achieve both EMS and phototherapy effects. ITO (Indium Tin Oxide) is a substitution solid solution, an inorganic composite material with high light transmittance and excellent conductivity. ITO conductive material is mainly composed of 90% indium oxide (In2O3) and 10% tin oxide (SnO2). This material has a light transmittance of 85% to 95% in the visible light range of 400 to 700 nanometers, while also possessing low resistivity. This combination gives ITO unique advantages in optical transparency and conductivity. Currently, ITO conductive materials are generally used in fields such as displays, touch screens, electronic paper, organic light-emitting diodes, and solar cells. This application applies ITO to the field of beauty device technology, breaking through the current technical bottleneck in this field and providing a brand-new breakthrough EMS beauty device that can better fit the human body, has good contact effect, is easy to clean, has good waterproof performance, and can be combined with phototherapy components.

[0043] The size and shape of the contact surface of the conductive element 100 can be determined according to the body contact area required for the actual application of the beauty device. In some embodiments, the crystal of the conductive element 100 can be a square, rectangular, elliptical, or circular sheet, or a three-dimensional shape with curvature, such as a shape similar to a convex lens. The conductive element 100 can be a sheet or a three-dimensional shape with curvature, and the contact surface of the crystal can be a plane or an arc surface, which can have a certain curvature to adapt to the curve of the human body for better fit. In one embodiment, the conductive element 100 is a sheet. Specifically, the conductive film is deposited on the sheet crystal by electroplating. The area of ​​the conductive film can be the same as, approximately the same as, or smaller than the area of ​​the sheet crystal. In some embodiments, the conductive film is electrically connected to the electronic control board 901 via a connecting wire; or the contact end of the beauty device is provided with a metal positioning component, for example, the front shell 903 is made of metal, and when the conductive component 100 is fixed on the front shell 903, the conductive film is in electrical contact with the metal front shell 903, and the metal front shell 903 is electrically connected to the EMS assembly and the electronic control board 901.

[0044] The main housing 902 is also provided with a button group 907, which is electrically connected to the electronic control board 901. The beauty device includes a power supply assembly, which includes a power interface; the power interface is electrically connected to the electronic control board 901 to connect to an external power source. In this first embodiment, the power supply assembly includes a battery 906, which is installed in a cavity inside the housing of the beauty device and electrically connected to the electronic control board 901; or in other embodiments, the battery 906 is installed in an external power socket, which is provided with a power circuit board electrically connected to the battery 906, and the power circuit board is electrically connected to the power interface.

[0045] Please refer to Figure 2. The difference between Embodiment 2 and Embodiment 1 is that, in Embodiment 2 of this application, the beauty device includes at least one annular semiconductor cooling element 200. The semiconductor cooling element 200 includes an electric dipole particle layer and hot and cold surfaces at both ends. The semiconductor cooling element 200 is disposed adjacent to the conductive element 100, and the hot or cold surface of the semiconductor cooling element 200 is in contact with the conductive element 100.

[0046] The fundamental principle of semiconductor isothermal refrigeration is based on the thermoelectric effect, particularly the Peltier effect. When direct current passes through a thermocouple composed of P-type and N-type semiconductor materials, the energy level difference of charge carriers (electrons or holes) in the materials causes heat absorption and release at the two ends of the thermocouple, respectively, thus achieving cooling. By precisely controlling the magnitude and direction of the current, the cooling effect can be precisely adjusted to achieve constant temperature. Semiconductor isothermal refrigeration has many advantages, such as no moving parts, no refrigerant, no pollution, no vibration or noise, long lifespan, and easy installation. Furthermore, it can both cool and heat, has high heating efficiency, and can achieve high-precision temperature control through input current control. It also has low thermal inertia and fast cooling and heating speeds. These characteristics have led to the widespread application of semiconductor isothermal refrigeration technology in many fields, such as electronic equipment cooling, medical devices, food preservation, air purification, and military and scientific research. In practical applications, semiconductor isothermal refrigerators are usually designed as miniaturized and lightweight products for easy use in small equipment and space-constrained environments.

[0047] In a specific embodiment, the conductive film in the conductive element 100 is disposed on the side of the sheet-like crystal facing outwards from the beauty device, and the other side of the sheet-like crystal is in contact with the cold or hot surface of the semiconductor cooling element 200. The semiconductor cooling element 200 is used to cool the conductive element 100, with its cold surface transferring heat to the conductive element 100; or the semiconductor cooling element 200 is used to heat the conductive element 100 or maintain it at a constant temperature, with its hot surface transferring heat to the conductive element 100. This forms a peripheral cooling / heating / temperature-regulating effect on the conductive element 100, with a corresponding annular central void area in the semiconductor cooling element 200 allowing light waves to pass through. Specifically, the hot surface of the semiconductor cooling element 200 can be one or a combination of several of the following: a heat pipe, a vapor chamber, a superheatable heat pipe, a superheatable heat-conducting plate, or a heat-conducting substrate made of a single thermally conductive material.

[0048] In Embodiment 1, the semiconductor cooling element 200 is used to cool the conductive element 100. Its cold surface is in heat transfer with the conductive element 100, and its hot surface is in heat conduction contact with the heat-conducting element 211 of the heat dissipation assembly. The heat-conducting element 211 is in heat conduction contact with the heat sink 212. The heat dissipation assembly also includes a fan 213 disposed above the heat sink 212.

The semiconductor cooling element 200 may also be a smaller, square, rectangular, elliptical, circular, triangular, or other geometric shape. Multiple semiconductor cooling elements 200 may be arranged in combination and contacted inside the conductive element 100. The gap in the arrangement of the semiconductor cooling elements 200 is not limited to the center; it may also be on one side or in other areas arranged in different ways. In beauty devices without light-emitting effects, no light-transmitting area is required. In beauty devices with light-emitting effects, the location of the light-transmitting area is not limited in this application.

[0050] Please refer to Figures 3 and 4. The difference between Embodiment 3 and Embodiments 1 and 2 is that the beauty device further includes a light source component. This light source component is electrically connected to the electronic control board 901, and the light emitted by the light source component is emitted through the light-transmitting conductive element 100. When the light source passes through the light-transmitting conductive element 100, it can simultaneously act on the skin. The heating is assisted by the internal heating effect of near-infrared radiation resonating with water molecules in the dermis, instantly raising the temperature of the dermis and rapidly increasing the temperature of collagen. This increases the therapeutic effect while reducing the heat in the epidermis, achieving the most effective and efficient photoelectric effect. In photoelectric hair removal, the radio frequency heat source can instantly increase the temperature of the dermis and hair follicles, efficiently increasing the temperature of the hair follicle root even when the epidermal temperature is low, effectively improving the efficiency of hair removal.

The insulation plate 908 fits into the inner wall of the outer casing to form a relatively enclosed space for installing the electronic control board 901, thus protecting the electronic control board 901. The lamp holder 314 and the insulation plate 908 can be the same bracket or two independently installed brackets.
