Product Name: Photocatalyst Electric Toothbrush Model NO.: olks-ys100 Certification: DOT, E-MARK, CE, ISO, FCC, RoHS, MUTCD, ASTM, AS/NZS, CCC, GS Materials of Bristle: Nylon Usage: Home, Travel, Hotel Bristle Type: Soft Folded: Folded Age Group: Adults Product Description Working principle of acoustic photocatalytic electric toothbrushAcoustic photocatalytic electric toothbrush combined with the latest photocatalytic titanium dioxide plus high frequency (31000 min) acoustic vibration can effectively remove tartar and maintain oral health.After the carbon dioxide semiconductor absorbs the energy from the sunlight or other light sources, the electrons on the surface of the particles are activated and escape from the original orbit, at the same time, the surface generates positive holes. The escaping electrons have strong reducibility, while the holes have strong oxidizability. When they react with water, they will form active oxygen and oxyhydrogen radicals. Active oxygen and hydrogen oxygen free radicals can oxidize most organic matters, pollutants, odor, bacteria, etc. into harmless carbon dioxide and water. Titanium dioxide patent technology is used in this product to greatly improve the photocatalytic effect.On the basis of titanium dioxide photocatalysis, a built-in power supply is used to provide a continuous current of 1-5 μ a to enhance the removal effect of tartar.At the same time, the sonic photocatalytic toothbrush uses the "cavitation effect" of the sonic vibration energy in the periodontium to remove the periodontal bacteria and impurities. The cleaning range can cover all parts of the periodontium. The MCU driving circuit installed in the hollow brush handle excites and generates vibration and transmits acoustic energy. The acoustic energy is transmitted to the teeth and gingival surface through the bristles of the brush head. On the one hand, it can loosen the adhesion of plaque, tartar and small calculus to the teeth, destroy the parasitic reproduction of bacteria in the gingival pocket and the hidden places of the tooth surface. On the other hand, the acoustic energy transmitted to the gingival surface through the bristles touching the gingiva penetrates into the gingival interior, acts on the cell membrane, accelerates the blood circulation, and new growth Aging metabolism can inhibit periodontitis and gingival bleeding, and prevent gingival atrophy.
