Toothbrush cylinders two twins with rotating protector. Characterized by two attachable parts together, first, which is the mango brush (16) inside which there is an electric motor (m) where you pass a rod (13), which comes out handle with stretch ( 12). The second piece is a housing (17) inside which there two cylindrical brushes (1 and 2) that are all on the outside surrounded by bristled toothbrushing; both brushes are fixedly a shaft (sy 11) and have cogwheels left and right subject to fixed same axis (4 and brush 14 1; 7 and brush 17 2); these sprockets connect with each other (4-5, 5-6, 6-7, 14-15, 15-16, 16-17) wheels are all the same size for both brushes from rolling at the same speed. So that give you the shaft movement n. 9 in the direction clockwise by action bearing steering both brushes will revolve concentrically, as shown in figures 3 and 6. The axes (8, 9, 10 and 11 ) rely on inside the case, could turn on themselves. Covering casing bearing, and brushes aside for the opposite of friction with your teeth. Casing (17) is engaged by a joint (18) to the end of the brush handle (15) where does a kindred striatum (12) which engages the hole (3) made in the shaft (9) generating movement concentric rotation is a brush, figures 3 and 6.
