Abstract

The utility model relates to a toothbrush. Both ends of a connection shaft are respectively connected with a rotary shaft of a mini motor, and a supporting body at the back section of a brush body. The connection shaft is provided with one radial eccentric block. The periphery of the supporting body at the back section of the brush body is movably supported in the front section of a brush handle. Therefore, the utility model improves dental cleaning ability and gingival massage effect.

Description

The whirling vibration toothbrush

This utility model relates to a kind of toothbrush.

At present, except that traditional manual brushes toothbrush, electronic rotary tooth-brush appears also, not only laborsaving, save time and toothbrushing effect also better, still, teeth space, recess tartar still are difficult for being come off by brush.

In view of this, the purpose of this utility model provides a kind of whirling vibration toothbrush, and it is to utilize the toothbrush rotation also to produce vibration when brushing teeth, and more favourable tartar and other fouls cleaned with water strengthened the massage effect to gingiva simultaneously.

The purpose of this utility model is achieved in that it comprises brush handle, micro machine, connecting axle, brush body and battery case, wherein the connecting axle two ends connect respectively in the back segment supporting mass of the rotating shaft of micro machine and brush body, it is characterized in that: a radial eccentric block is set on the connecting axle, and the back segment supporting mass outer rim of brush body is bearing in the brush handle leading portion versatilely again.

Described brush body is that its cylinder outer rim and front end face all are provided with bristle by two bonding one-tenth one cylinders of semicolumn shell.

Described battery case outer rim is provided with the elasticity electric switch.

Owing to adopt such scheme: increase to the ability of cleaning with water of tooth and to the massage effect of gingiva.

Below in conjunction with drawings and Examples this utility model is further specified.

Fig. 1 this utility model exemplary embodiments sketch map.

Among the figure: 1, brush handle, 2, micro machine, 3, connecting axle, 31, eccentric block, 4, brush body, 41, supporting mass, 42, bristle, 5, battery case, 51, the elasticity electric switch.

Present embodiment comprises brush handle 1, micro machine 2, connecting axle 3, brush body 4 and battery case 5, as shown in Figure 1, and wherein:

Brush handle 1 is that leading portion is thin, the hollow cylindrical shell of the stairstepping that back segment is thick, an affixed micro machine 2 (stator casing with micro machine 2 is fixed in the brush handle 1) in the back segment of this brush handle 1;

Connecting axle 3 is rotating shafts that an eccentric block 31 radially is set on it, when connecting axle 3 is rotated, can produce radial vibration, this connecting axle 3 is to be connected in the rotating shaft of micro machine 2 with its rear end, and the front end of this connecting axle 3 connects in the brush body 4 back segment supporting masses 41, this brush body 4 is cylindrical shell (by two bonding one of semicolumn shell), these brush body 4 back segment supporting masses 41 outer rims are bearing in brush handle 1 leading portion versatilely again, so that stably support brush body 4, cylinder outer rim and front end face at brush body 4 are inserted with many bristles 42, and wherein the bristle 42 of front end face is that time spent boil on the nape opposite the mouth intracavity carries out local cleaning and massage (the oral cavity inner region that the bristle 42 of cylinder outer rim is difficult for entering).

Battery case 5 is box bodys of internal battery, connect (interlocking or grafting) opening part with its front end at brush handle 1 back segment, also be provided with an elasticity electric switch 51 on its outer rim, be connected on micro machine 2 and the anastomosing circuit of battery, when hand-held these battery case 5 outer rims, promptly just connect by compression elasticity electric switch 51 foregoing circuits, micro machine 2 is just rotatable, when driving brush body 4 rotations, eccentric block 31 makes brush body 4 also produce the radial disbalance vibration, therefore, brush body 4 cylinder outer rim bristles 42 ceaselessly also produce radial vibration when dental surface or gingiva are cleaned with water, strengthen dental surface and the cleaning effect of ditch seam and the massage effect of gingiva; When openhanded battery case 5 outer rims of opening, elasticity electric switch 51 is to be in the cut-out circuit state, and micro machine 2 does not rotate, and natural brush body 4 does not rotate.
