Description

Improved electric toothbrush

Technical field

This utility model belongs to the improvement of electric toothbrush, particularly improved electric toothbrush.

Background technology

At present, people have got used to using common plastic tooth brush to be brushed teeth, though the common plastics toothbrush is cheap, easy to use, brush teeth but need move respectively along the inside and outside two sides of tooth when brushing teeth, and the motion mode of toothbrush is left and right sides transverse movement, and is vertical with teeth space, and difficulty once cleans down tooth.In addition, publication number is that the Chinese invention patent ublic specification of application of CN1528250A also discloses a kind of pair of brush electric toothbrush, it is to be moved back and forth by built-in motor drives brush to brush teeth, though two brushes can improve brushing efficiency, but the direction of motion of brush is also vertical with teeth space, thereby its outwash rate to tooth is still not high.

The utility model content

The purpose of this utility model is to provide a kind of improved electric toothbrush, can be once with tooth innner and outer, three outwashes in top, and the direction of motion of toothbrush bristle is consistent with the direction of teeth space, to the outwash rate height of tooth.

The purpose of this utility model is achieved in that a kind of improved electric toothbrush, comprise brush holder and be installed in the interior motor of brush holder, three rotating shafts are being set in the front end of brush holder, the rotating shaft outboard end that stretches out in the brush holder is being provided with the brush that has bristle respectively, bristle on three brushes contacts with inside and outside, three outer peripheral edges in top of people's tooth respectively, the rotating shaft medial extremity that is positioned at brush holder is equipped with driven gear respectively, and these three driven gears are meshed with the driving gear that is installed in motor shaft end respectively.

When this utility model uses, connect the power supply of motor, three of motor drives are equipped with the rotating shaft rotation of brush, because the bristle on three brushes contacts with inside and outside, three outer peripheral edges in top of people's tooth respectively, need only like this and these three brushes are put into the oral cavity encase corresponding tooth and tooth can be cleaned down.Can be once with tooth innner and outer, three outwashes in top, and the direction of motion of toothbrush bristle is consistent with the direction of teeth space, to the outwash rate height of tooth.This utility model is simple in structure, and volume is small and exquisite, and low production cost is easy to promote.

The specific embodiment

A kind of improved electric toothbrush as shown in Figure 1 and Figure 2, comprises brush holder 6 and is installed in motor 5 in the brush holder 6 that brush holder 6 be a hollow pipe, and this hollow pipe can be used plastics, resin or stainless steel tube formation.Between the tail end of brush holder 6 and motor 5 battery 8 being installed, is motor 5 power supplies by battery 8.Three rotating shafts 2 are being set in the front end of brush holder 6, and rotating shaft 2 outboard ends that stretch out in the brush holder 6 are being provided with the brush 1 that has bristle respectively, and as shown in Figure 3, the bristle on three brushes 1 contacts with inside and outside, three outer peripheral edges in top of people's tooth respectively.Rotating shaft 2 medial extremitys that are positioned at brush holder 6 are equipped with driven gear 4 respectively, and these three driven gears 4 are meshed with the driving gear 3 that is installed in motor shaft end respectively.As shown in Figure 2, a transition gear 7 is being set also in brush holder 6, this transition gear 7 is meshed with driving gear 3 and three driven gear 4 one of them driven gears respectively.The effect that transition gear 7 is set is to guarantee and contacted two brushes 1 in the people's tooth two sides seam of can both brushing teeth from bottom to top of the bristle on it when rotated.For brush 1 and people's dental bed radian are matched, three rotating shafts 2 all adopt Bowden cable to constitute, and such Bowden cable can be done suitable bending, this brush, during lower incisor, can be more convenient.
