detailed description

The present invention is described in more detail below with reference to the drawings and embodiments.

The present invention discloses an electric toothbrush based on LED light care. As shown in FIG. 1 to FIG. 3, it includes a handle 1, a front end of the handle 1 is provided with a brush handle 2, and a front end of the brush handle 2 is provided. The brush head 3 is provided with a driving mechanism 4 for driving the brush handle 2 to vibrate and a circuit board 5 in the handle 1. An LED light emitting plate 6 is provided in the brush head 3, and the LED light emitting plate 6 is provided in the handle 1. There are multiple LED chips 60. The LED light emitting board 6 and the driving mechanism 4 are electrically connected to the circuit board 5, respectively. The multiple LED chips 60 are used to emit red light, infrared light and / or ultraviolet light. The brush head 3 There are bristles 30, and the brush head 3 and / or the bristles 30 are made of light-guiding material.

In the electric toothbrush, driven by the driving mechanism 4, the brush handle 2 and the brush head 3 vibrate accordingly, thereby achieving the cleaning effect on the teeth. At the same time, under the irradiation of the LED light-emitting board 6, red light and infrared light can be used , Ultraviolet light, or any combination of the three combined light for oral care, allowing users to clean their teeth while achieving light care of the oral cavity. Based on the above-mentioned electric toothbrush, users do not need to purchase additional oral light care products, which not only satisfies users Demand, and save the user's use costs.

The plurality of LED chips 60 in the LED light-emitting board 6 can be used to emit red light, infrared light, and / or ultraviolet light. Among them, the care effect of various colored lights is as follows:

In the LED light biological care technology, red light includes red light with a wavelength λ between 630nm and 640nm and a power between 400μW and 550μW, which can penetrate 5.5 ~ 7mm under the skin. The red light has the effects of promoting aging, improving blood circulation, increasing skin collagen, increasing skin elasticity, and smoothing fine wrinkles. Main clinical applications: anti-aging, whitening, skin rejuvenation, moisturizing and radiant skin, tenderness, repairing wounds, treating allergic skin, stopping hair loss, hair growth, improving dry skin, soothing fatigue, improving sleep and relaxing mood. The maximum absorption of red light is mitochondria. After red light irradiation, the catalase activity of mitochondria can be increased. This can increase cell metabolism, increase glycogen content, increase protein synthesis and increase adenosine triphosphate decomposition, so it can promote cell synthesis, can promote wound and ulcer healing, promote hair growth, promote fracture healing, and accelerate the damage of nerves. Regeneration, while also increasing the phagocytosis of white blood cells, so it can treat a variety of diseases clinically;

In the LED photobiological care technology, light in the infrared spectrum includes infrared light having a wavelength λ between 830 nm and 880 nm and a power between 190 μW and 310 μW. The infrared light is absorbed by resonance, and the frictional heat between the molecules forms a thermal reaction, which promotes the deep temperature of the subcutaneous layer, expands the microvasculature, and accelerates blood circulation, which is conducive to clearing blood vessel accumulations and harmful substances in the body, which will hinder the new generation of radiation. Obstacles are cleared, tissues are resurrected, and enzyme production is promoted to achieve the purpose of activating tissue cells, preventing aging, and strengthening the immune system. Main clinical applications: the purpose of improving the microcirculation system, good anti-inflammatory effects of wounds, regulating the normalization of autonomic nerves, preventing aging, and strengthening the immune system;

In LED light bio-care technology, ultraviolet light has shorter wavelength than visible light, but longer electromagnetic radiation than X-rays. The wavelength of ultraviolet light in the electromagnetic spectrum is 10-400nm. This range starts at the short-wave limit of visible light and overlaps with the long-wavelength of X-rays. Ultraviolet light is divided into A-rays, B-rays, and C-rays (UVA, UVB, and UVC for short), with wavelength ranges of 400-320nm, 320-280nm, 280-190nm. UVB is ultraviolet light having a wavelength of 280 to 320 nm. Medium-wave UV has certain physiological effects on human skin. A large part of this ultraviolet light is absorbed by the skin epidermis and cannot penetrate into the skin.

In this embodiment, in order to facilitate the installation of the LED light-emitting board 6, a recess is formed on the side of the brush head 3 facing away from the bristles 30, the LED light-emitting board 6 is disposed in the recess, and the brush head 3 is fixed There is a cover plate 31 which covers the notch, and the connection between the cover plate 31 and the brush head 3 is sealed.

Regarding the specific composition of the driving mechanism, the driving mechanism 4 includes a motor 40, and a connecting rod 41 is fixed to the rotating shaft of the motor 40. The connecting rod 41 extends to the front of the handle 1, and the rear end of the brush handle 2 A plug-in member 20 is provided. A jack is opened at the rear end of the plug-in member 20. The connecting rod 41 is inserted in the jack, and the connecting rod 41 is in interference with the plug-in member 20. Cooperate.

Further, a rechargeable battery 7 is provided in the handle 1, and the rechargeable battery 7 is electrically connected to the circuit board 5.

In this embodiment, a bracket 8 is fixed in the handle 1, and the motor 40 and the rechargeable battery 7 are both mounted on the bracket 8.

In order to facilitate disassembly, battery replacement, and maintenance of the internal structure of the handle 1, in this embodiment, two ears 80 are formed at the rear end of the bracket 8, and the rear cover of the handle 1 is combined with a rear cover. 9. Two buckles 90 are formed on the front side of the back cover 9. The two buckles 90 are sandwiched between the two ears 80, and the buckles 90 are connected to the ears 80 in an engaged manner.

The above are only preferred embodiments of the present invention, and are not intended to limit the present invention.
