Abstract
The utility model relates to a dual-shaft electric toothbrush, comprising an outer shell, a battery, an electric motor, brushing shafts, plastic-blasting magnetic sheets, brushing hair, a non-corrodible steel three-jaw clamp and a transmission-retarding mechanism, characterized in that the transmission-retarding mechanism is composed of a suite of worm gear double reduction device and a plurality of transmission gears. The brushing hair of the two brushing shafts are compactly arranged in 4-6 columns along the axial direction, then pressed by the plastic-blasting magnetic sheets after being uniformly distributed in three rows according to the axial circumference, and then fixedly clamped by the non-corrodible steel three-jaw clamp. The brushing hair of the two brushing shafts crisscross mutually and together form an approximate oval-shaped rotating cross-section when they are relatively rotating towards one another. The length of the brushing hair of the two brushing shafts is suitable when the two parts of the brushing hair are able to mutually and slightly contact the plastic-blasting magnetic sheets of each other in rotation. The utility model has a good mouth feel and is an ideal health care product for teeth.
Description
This utility model relates to a kind of twin shaft electric toothbrush.
In the patent No. is that the name of 92207117.9 issues is called in the utility model patent of " twin shaft electric toothbrush " and discloses a kind of twin shaft electric toothbrush, and the main shortcoming of this toothbrush is that rotating speed is on the low side, and body brush is changed trouble, and mouthfeel is bad when brushing teeth.
The purpose of this utility model is exactly the weak point that overcomes on the above-mentioned prior art, and a kind of improved twin shaft electric toothbrush is provided.
This utility model comprises shell, battery, motor, brush axle, plastic-blasting magnetic sheet and bristle and transmission speed reducer structure.The transmission speed reducer structure is made of a cover worm gear pole double reduction gear and some travelling gears.Two bristles of brushing on the axle are that 4-6 row closely arranges vertically, circumferentially are divided into triplex row with axle, the rotation cross section of an approximate ellipsoidal of interlaced common formation when the bristle on the diaxon rotates.Be fixed on the thick about 0.8 millimeter watt type plastic-blasting magnetic sheet on the brush axle, can magnetize, be very beneficial for child and teen-age oral health the water of brushing teeth.
Be further described below in conjunction with accompanying drawing:
Figure one is this utility model structural representation.
Figure two is an A-A cutaway view among the figure one.
Among the figure: 1, shell 2, battery 3, micro machine 4,15, worm gear 7,13, worm screw 5,6,8, gear 9, oiliness bearing 10, change that brush is recessedly taken turns 16, changed brush cam 11,17, brush axle 12,18, bristle 14, switch 19, rustless steel three-jaw card 20, surface plastic spraying magnetic sheet.
Worm screw 13 directly is contained on the motor 3, and worm screw 13 drives worm gear 4 rotations, finishes one-level and slows down.Gear 5 is annotated for one, with worm gear 4 equidirectional rotations with worm gear 4.Transmission of power is finished in 6 opposite spins of gear 5 driven gears, and gear 6 is annotated with worm screw 7 and is one, and gear 6 drives worm screw 7 equidirectional rotations.Drive worm gear 15 rotations by worm screw 7, finish double reduction.Brush axle 17 is by changing brush convex-concave wheel and worm gear 15 equidirectional rotations, brush axle 11 is by changing brush convex-concave wheel and gear 8 equidirectional rotations, gear 8 is driven by worm gear 15, brush axle 11 forms changeing with brush axle 17, as use popular 9400 rev/mins micromachine, adopt this worm-drive reducing gear, brush axle rotating speed is reduced to about 400 rev/mins, mouthfeel as snug as a bug in a rug during use.
Bristle the 12, the 18th on the two brush axles, 2-3 row is side by side vertically, push down respectively with 3 plastic-blasting magnetic sheets then, again by rustless steel three-jaw card with plastic-blasting magnetic disk card jail, be formed on brush circumferential 1/3 a uniform and edge brush body brush that axial linearly extended 4-6 row * 3 goes, bristle diameter is the 0.08-0.1 millimeter, and mouthfeel as snug as a bug in a rug when brushing teeth.The plastic-blasting magnetic sheet that contacts the other side when bristle 12,18 length are with rotation on the two brush axles 11,17 mutually slightly is advisable, it is interlaced and form the rotation cross section of an approximate ellipsoidal jointly when 12,18 pairs of the bristles of two brush axles change, basically having eliminated in the patent No. is that 912013427 names of issuing are called formed dead angle area between " twin shaft electric toothbrush " diaxon bristle, this utility model toothbrushing effect is fine, be more suitable for child and teenager and use, simultaneously gingiva is had the good health care massage effect.
