The brush hair of the two brushing shafts are both compactly arranged in 2-5 columns along the axial direction, and then pressed by the stainless steel battens after uniformly distributed in four rows according to the circumferences of the brush shafts; finally the brush hair is fixedly sheathed by both ends of each of the circular stainless steel sleeves. The brush hair of the two brush shafts can cross mutually and together form an approximate oval rotating cross-section when rotated toward one another. The length of the brush hair on the two brush shafts is suitable when the brush hair can mutually and slightly contact the stainless steel shafts and the stainless steel battens of each other in rotation.

Description

Motor driven tooth-brush with two brush head placed in an anlgle

This utility model relates to the electric toothbrush of a kind of novel two brush alternating expression.

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 the deceleration device adjusting range is little, and the aneroid battery power consumption is bigger, and the mouthfeel of brushing teeth is relatively poor.

The purpose of this utility model is exactly the deficiency that overcomes on the above-mentioned prior art, and the electric toothbrush of a kind of improved novel two brush alternating expression is provided.

This utility model includes shell, battery, micro machine, stainless steel brush axle, rustless steel press strip, nylon brush hair, rustless steel circle cover and transmission speed reducer structure, it is characterized in that the transmission speed reducer structure is made of a cover worm and gear basin type gear double reduction gear and some travelling gears.It all is that 3-5 row (presses all ages and classes vertically that two brush axles are gone up bristle, different mouthfeels) closely arrange, again by pushing down with the rustless steel press strip after the circumferential uniform four lines of brush axle, reuse rustless steel circle entangles firm, bristle on the two brush axles is interlaced and constitute the rotation cross section of an approximate ellipsoidal jointly when changeing, and is particularly advantageous in child and teen-age oral health.

Be further described below in conjunction with accompanying drawing:

Figure one is a structural representation of the present utility model.

Figure two is an A-A cutaway view among the figure one.

Among the figure: 1, shell 2, battery 3, micro machine 4, gear (duplex)

5, worm gear (duplex) 6,7, gear (duplex) 8, ring gear

9, to alternation of hosts's moving gear 10, inferior to changeing driven gear

11,17, brush axle 18, rustless steel circle cover (totally 4) 12,19, bristle

13, worm screw 14, duplex on and off switch 15, oiliness bearing

16, to changeing driven gear

20,21,22,23, rustless steel press strip

Worm screw 13 is directly installed on the motor 3, the motor rotation, and worm screw 13 drives worm gear 5 and is rotated counterclockwise, and finishes one-level and slows down.Gear 4 is the duplicate gear that forms one with worm gear 5, and gear 4 is with worm gear 5 equidirectional rotations.Gear 4 driven gears 6 turn clockwise, and finish the speed governing transmission.Gear 6 is the duplicate gear that forms one with gear 7, and the 7 equidirectional rotations of gear 6 driven gears drive ring gears 8 by gear 7 and are rotated counterclockwise, and finish double reduction.Ring gear 8 drives the 9 equidirectional rotations of alternation of hosts's moving gear, and alternation of hosts's moving gear 9 is driven changeing driven gear 16 opposite spins.Brush is convenient to be designed gear 10 in order to change specially.Drive time to changeing driven gear 10 opposite spins changeing driven gear 16, brush axle 11 and brush axle 17 formed changeing, the upper tooth of finishing science from top to bottom, lower tooth vertical tooth brushing method from lower to upper.As use popular 9400-10000 rev/min micro machine, adopt this worm and gear ring gear double reduction gear, the number of teeth of change gear 4,6 and worm gear 5, brush axle rotating speed is regulated between 250-600 rev/min, produced the different novel two brush alternating expression electric toothbrush of the mouthfeel of brushing teeth.

Nylon brush hair the 12, the 19th on the two brush axles, the 3-5 layer neatly twines vertically, push down respectively with 2 rustless steel press strips then, reuse rustless steel circle cover entangles stainless steel shaft and rustless steel press strip two firm, again bristle is trimmed by Len req, be formed on brush circumferential 1/4 a uniform and edge brush body brush that axial linearly extended 3-5 row * 4 goes.Bristle diameter is respectively the 0.05-0.08 millimeter with regard to all ages and classes, and mouthfeel as snug as a bug in a rug when brushing teeth.Bristle 12,19 length are advisable with the stainless steel shaft and the rustless steel press strip that contact the other side when changeing mutually slightly on the two brush axles 11,17, it is interlaced and constitute the rotation cross section of an approximate ellipsoidal jointly when 12,19 pairs of the bristles on the two brush axles change, basically the name of having eliminated in the patent No. 91201342,7 issues is called formed dead angle area between " twin shaft electric toothbrush " diaxon body brush, have good toothbrushing effect, be particularly suitable for teenager and child and use.

This utility model has adopted the duplex on and off switch of science, thoroughly solved general simply connected on and off switch close the back afterbody+-the dark power consumption phenomenon of the utmost point, the aneroid battery life-span was extended to about 30 days from present use in 20 days, 0.02 yuan of day power consumption expense less than, very economical.Use this utility model to be equipped with the Kowloon fluid port cleaning that Shanghai produces, toothbrushing effect is fine, and gingiva is had good health care massage effect.
