Description

Phototherapy skin care instrument based on flexible alternating current planar electroluminescent device

Technical Field

The utility model relates to an electroluminescent skin care appearance technical field especially relates to a phototherapy skin care appearance based on flexible interchange plane electroluminescent device.

Background

After the skin is irradiated by low-intensity light, the biological effects of photo-thermal, photo-immune, photochemical and the like can be generated, thereby treating the vascular diseases of the skin and the epidermis. And the monochromatic light with different wavelengths has different regulating action mechanisms on target organs of the skin. Therefore, different low-intensity lights are clinically applied to different treatments, such as skin lesion repair, anti-inflammation and the like. The infrared ray application wavelength is 760 to 10⁶nm, the thermal effect and the non-thermal effect of infrared rays are combined, so that the capillary vessel can be expanded, and the blood flow is accelerated. Effectively improve blood circulation, further increase tissue supply and substance metabolism and improve blood circulation, further generate positive biomedical effects of increasing tissue supply and substance metabolism, improving nutritional state, enhancing immune function and the like. AThe light with certain wavelength can play different roles and even improve the skin: when the skin is irradiated with 610-760nm red light, the respiratory chain in mitochondria of subcutaneous tissue cells can be disturbed, calcium ions and adenosine triphosphate are promoted to be increased, the cell activity is increased, the proliferation and migration of human fibroblasts are stimulated, the activity and content of enzyme related to skin photoaging are reduced, and the skin photoaging can be effectively delayed; in recent years, blue light has an antibacterial and calming effect, and adverse reaction and drug resistance can not be caused by using blue light for antibiosis. When 445-450nm blue light is irradiated on the skin, the light acts on the surface layer of the skin, and the effects of stabilizing the skin state, controlling oil and removing acnes can be achieved. When orange light with the wavelength of 600-610nm is provided for the skin, the orange light acts on the subcutaneous layer, the alternate function of cell oxygen is improved, the microcirculation is improved, and the effects of whitening the skin and lightening the pigmentation are achieved.

In the sales of skin care products in the market, the mask products are far ahead. However, in the traditional mask applying mode, most of nutrient elements in the mask can only stay in the epidermis layer, and the use rate of the nutrient elements in the mask is extremely low. If the active ingredients are prepared into the nano needle-shaped structure, the skin surface layer is punctured, and the nutrient elements are conveyed to the deep layer of the skin, so that the absorption efficiency of the nutrient elements can be greatly improved.

With the continuous progress of the technological level, there are many products or technologies that irradiate the skin with light rays of different wavelengths, so as to improve the skin problem and maintain the skin. However, most of these skin care devices are expensive and time consuming, and are not suitable for the general public with skin care needs. The existing mask instrument which takes an LED lamp as a light source to realize dot matrix luminescence in the market has the problems of large instrument weight, heavy instrument, low fit degree with the face, uneven illumination, poor use experience, local skin damage and sensitivity caused by overlong illumination time and the like, so that the development and application commercialization of the mask instrument are limited to a great extent. The flexible substrate luminous mask instrument which is made by taking the OLED as a luminous source can be attached to the face to a certain extent, but the flexible substrate luminous mask instrument is driven by a direct-current power supply to emit light, so that the luminous service life and the versatility of the instrument are limited.

The skin vibration applying frequency of 160-180 times/second has the following effects: (1) enhancing cell activity, and promoting facial muscle movement, thereby achieving the effect of recovering muscle elasticity; (2) accelerating blood circulation of blood capillary, promoting metabolism of face, enhancing cell permeability, and effectively supplying nutrients to muscle tissue and skin; (3) the microvibration can stimulate lymph glands, accelerate the absorption of the nutritional ingredients of the mask by the skin, promote the discharge of toxin waste, and supplement the moisture of the skin to enable the skin to be moistened, smooth and tender; (4) the high-frequency vibration enables energy stimulation to penetrate into subcutaneous tissues to muscles, and is beneficial to maintaining the stretch of elastic fibers and colloidal layers of the skin, so that the aim of reducing wrinkles is fulfilled.

The electroluminescent device driven by the alternating current power supply can balance current carriers in the working process of the instrument and prolong the service life; on the other hand, the device can generate high-frequency vibration when in work, thereby achieving the effect of massaging the skin. In addition, the traditional electroluminescent device is of a sandwich structure, an upper electrode and a lower electrode in the vertical direction need to be prepared, and the preparation process is complex; and the substrate in the traditional electroluminescent device needs to adopt a transparent ITO electrode, so that the production cost is high.

In addition, in the instrument cleaning process, the circuit board is easy to age and break down due to the fact that the circuit board is in contact with a panel containing moisture. Currently, there are techniques for applying LEDs to masks. For example, patent document CN102600555A discloses a red LED mask with a flexible circuit board. However, the LED mask instrument needs to be in direct contact with the skin of a human body, and the problem of sanitation and safety exists.

Accordingly, the prior art remains to be improved and developed.

The luminous layer adopts three organic materials and can respectively emit red light, orange light and blue light. A device structure as shown in fig. 14 is employed. The phototherapy skin care instrument using the device can achieve the functions of the phototherapy skin care instrument shown in fig. 12, and the main difference is that the substrate is discrete and can be adapted to more manufacturing processes. Compared with the device structure shown in fig. 13, the device can emit red/orange/blue polychromatic light in a pixel adjustment mode. The mask used in this example is a conventional patch mask. The film base material is silk, and the facial mask liquid comprises glycerol, ginkgo leaf extract, hyaluronic acid, jojoba oil, honey, betaine, graphene oxide and glycerol polymethacrylate, can effectively and durably preserve moisture, is also suitable for people with sensitive skin, and can play the best effect by matching with phototherapy. When the instrument shown in fig. 1 is used, the instrument is fixed on the head through the elastic bands on two sides. Switching on a household power supply, and controlling the voltage to be below 24V; after the power supply is switched on, the polyvinylidene fluoride (PVDF) substrate in the device can generate mechanical vibration by utilizing the piezoelectric effect, and the high-frequency vibration dual function generated when the device works is combined, so that the skin-to-facial mask essence absorption is effectively promoted.
