The purpose of this utility model is to solve the problem that people correctly brush teeth, and again gingiva is not produced injury simultaneously, improves the cleaning of teeth effect, saves brushing time.

This utility model is had the battery case of switch and is placed battery, micromachine, drive link, splicing sleeve, brush in the box to form by the double handle of doing, and drive link and its splicing sleeve are pegged graft with motor shaft and battery case respectively, and brush and drive link are pegged graft.Do power supply with universal battery, DC micromotor drives brush by drive link and rotates the purpose that reaches cleaning teeth.

Brush is hairbrush or soft toothpick, when brush is selected hairbrush for use, is peripherally equipped with the guard shield of an opening.

Above-mentioned battery is contained in double doing in the battery case that handle has switch, motor protective case and battery case are one, drive link and its splicing sleeve are pegged graft with motor shaft and motor protective case respectively, hairbrush and hairbrush guard shield are pegged graft with drive link and splicing sleeve respectively, hairbrush and guard shield are dialled down toothpick is inserted on the drive link when with toothpick.

Because the employing motor drives hairbrush or the rotation of soft toothpick by drive link in the above-mentioned solution, hairbrush is equipped with the guard shield of an opening outward, and hairbrush only contacts with tooth when brushing teeth, and has avoided bristle to contact with gingiva and has produced impact, the disadvantage of damage gingiva.Equally, use soft rotation toothpick, also can avoid periodontal soft tissue to sustain damage.

The utility model is described in further detail below in conjunction with drawings and Examples:

Fig. 1 is the structural representation of this utility model embodiment.

Fig. 2 is the side view of Fig. 1;

Fig. 3 is the structural representation of hairbrush;

Fig. 4 is the upward view of hairbrush;

Fig. 5 is the structural representation of nylon soft toothpick;

Fig. 6 is a nylon soft toothpick upward view;

In structural representation shown in Figure 1, drive link 3 is pegged graft with motor 5, splicing sleeve 4 is pegged graft with battery case main body 8, hairbrush 2 is pegged graft with drive link 3, guard shield 1 is pegged graft with splicing sleeve 4, motor 5 is installed in the battery case main body 8 upper motor shells, battery 9 is installed in the battery case main body 8, battery support plate 6 is installed in the battery case motor 5 and battery 9 is separated, and battery cathode contact 7, anode contact 12 are installed in respectively on the battery support plate 6, battery is communicated with the bottom that contact 10 is installed in battery case main body 8,11 is the switch contact, and 13 is shift knob, and 14 is the loam cake of battery case 8 among Fig. 1 among Fig. 2.

Push switch button 13 can make switch contact 11 be communicated with when this utility model used, and motor drives the hairbrush rotation by drive link.When using toothpick, need only get final product changing toothpick shown in Figure 5 under 2 groups of guard shield among Fig. 11 and the hairbrush.

This utility model is simple in structure, and dismounting is used, cleaning parts hygienic and convenient, is easy to more Brusher being able to change bristles or toothpick, has great practical value.
