Description

Electronic health protection toothbrush

This utility model relates to a kind of electric tooth brushing device.

At present, known toothbrush structure is made up of plastic handgrip and the hairbrush that is fixed on the plastic handgrip, during use utilization fixedly hairbrush brush teeth.But according to the requirement of health and health care, hairbrush should move down along tooth when brushing tooth; Brush during lower teeth hairbrush should move up along tooth, only in this way could more effective cleaning teeth and don't damage gingiva, and ordinary toothbrush will accomplish that this point difficulty is bigger, and the cleaning of tooth inner surface difficulty comparatively, and brushing time is longer.

The purpose of this utility model provides a kind of electric toothbrush, and it can clean the outer surface or the inner surface of lower teeth simultaneously, and hairbrush can move down along tooth when brushing tooth; Brush during lower teeth hairbrush can move up along tooth, and the county can tell and unloads and Brusher being able to change bristles more.Can keep proper teeth brushing way like this, can reduce brushing time again, and help the cleaning of tooth inner surface.

The purpose of this utility model is achieved in that whole toothbrush is made up of handle, toothbrush neck and head toothbrushes three parts.Power supply and small machine are arranged in the handle, fix an on and off switch on the handle; Machine shaft by toothbrush neck up to head toothbrushes; Head toothbrushes has two hairbrush that rotate around self rotating shaft respectively; and the hairbrush shaft parallel is provided with; side at two parallel hairbrush is covered with the protection outer housing; put a side of two parallel hairbrush simultaneously; at the pinion box that a water-tight is arranged near toothbrush neck one end; one end of the central rotating shaft of two hairbrush inserts respectively in the axis hole of protection on the outer housing, and the other end flexibly connects by two clutch teeth and two gear shafts in the gearcase respectively, so that dismounting and Brusher being able to change bristles more.Pressing on and off switch in use is energized, and two hairbrush backward rotation that the interior gear driven of gearcase has been passed through in the rotation of motor are changeed when brushing tooth top hairbrush downwards, and following hairbrush is to the upper rotary brush lower teeth.Again owing to have only machine shaft to pass through in the toothbrush neck, thus can be with neck design narrower, head toothbrushes can be put into the oral cavity like this and reach the purpose that brushes the lower teeth inner surface simultaneously.

Owing to adopted such scheme, people are when brushing teeth, and a hairbrush moves down when brushing tooth another hairbrush along the tooth brush lower teeth that moves up along tooth, can keep proper teeth brushing way like this, can save brushing time again, and help the cleaning of tooth inner surface.
