The purpose of this utility model also can be achieved through the following technical solutions, described electric toothbrush, and its characteristics are that described switch is a forward-reverse switch.Described electric toothbrush, its characteristics are that the motor shaft of motor meshes by driving gear and the driven reduction gearing that is loaded on brush head axis one end.Described electric toothbrush, its characteristics are provided with the brush lid for the brush body front end, brush covers the top of brush, brush one end is provided with hexagon ring and is nested with the hexagonal axle head of the brush head axis that stretches into the brush body front end and is connected, the axle that the brush other end is provided with is inserted in the axis hole that has on the brush lid respective inner walls, and the motor shaft that the brush head axis other end passes brush body front portion axis hole that is provided with and the cavity that is positioned at the brush body rear portion is connected.Described electric toothbrush, its characteristics are that forward-reverse switch is made up of button, two battery lead plates and two electrode shell fragments, button is made up of with the insulating support that the button bottom is connected button, button rotates around the rotating shaft of being fixed on the brush body, two battery lead plates be fixed on the insulating support surface of button and between two battery lead plates an alternate isolation recesses separate, correspondingly on brush body, be provided with the alternate two electrode shell fragments that separate.
This utility model drives brush by the rotation of motor rotation drive brush head axis and rotates, and the bristle on the brush is scrubbed tooth owing to adopt motor, reaches the purpose of brushing teeth.Thereby be simple in structure and convenient in use.
Below in conjunction with drawings and Examples this utility model is elaborated:
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is a construction of switch sketch map of the present utility model.
As shown in Figure 1 and Figure 2, this utility model comprises brush body 1, motor 2, brush 3, battery 4 and switch 5, described brush body 1 rear portion is provided with the cavity of built-in motor 2 and battery 4, the motor shaft of motor 2 is connected with brush head axis 6 one ends, brush head axis 6 other ends pass brush body front portion axis hole that is provided with and the brush 3 that is positioned at the brush body front end and are located by connecting, battery 4 is given motor 2 through a switch 5 power supplies, and the control motor rotates.Generally by driving gear 7 and driven reduction gearing 8 engagements that are loaded on brush head axis 6 one ends, driving gear 7 rear upper end are provided with toroidal baffle plate 9 to the motor shaft of motor 2, and the toroidal baffle plate blocks driven reduction gearing does not allow it move backward.Brush body 1 front end is provided with brush lid 10, brush covers the top of brush, make bristle 11 on the brush be difficult for making dirty and brush oral cavity wall bitterly around can not brushing the chamber of shutting up owing to the top bristle of brush is covered the bristle that makes brush head upper divide by brush, brush one end is provided with hexagon ring and is nested with the hexagonal axle head of the brush head axis that stretches into the brush body front end and is connected, the axle that the brush other end is provided with is inserted in the axis hole 12 that brush lid respective inner walls is provided with, and the motor shaft that the brush head axis other end passes brush body front portion axis hole that is provided with and the cavity that is positioned at the brush body rear portion is meshed with driven reduction gearing by driving gear and is connected.Described switch 5 adopts forward-reverse switch, forward-reverse switch is by button, two battery lead plates 14 and two electrode shell fragments 15 are formed, button is made up of the insulating support 18 that button 13 is connected with the button bottom, button rotates around the rotating shaft 17 of being fixed on the brush body, two battery lead plates 14 be fixed on the insulating support surface of button and between two battery lead plates an alternate isolation recesses 16 separate, correspondingly on brush body 1, be provided with the alternate two electrode shell fragments 15 that separate, when connecing battery cathode when being positioned at that battery lead plate near button connects anode and away from the battery lead plate of button, press to one side when button and to make it to rotate and make and run into the corresponding electrode shell fragment of being located on the brush body near the battery lead plate of button around being fixed in rotating shaft on the brush body, this electrode shell fragment connects the motor positive pole, and run into the corresponding electrode shell fragment of being located at the opposite side on the brush body away from another battery lead plate of button, this electrode shell fragment connects the motor negative pole, thereby makes motor around forward rotation; Press to another side when button and to make it to rotate and make and run on the electrode shell fragment of the opposite side of being located on the brush body near the battery lead plate of button around being fixed in rotating shaft on the brush body, this electrode shell fragment connects the motor negative pole, and run into the electrode shell fragment of being located on the brush body away from another battery lead plate of button, this electrode shell fragment connects the motor positive pole, thereby makes motor because rightabout electric current feeds around backward rotation; In the middle of button is positioned at and do not rotate, then touch respectively in the lip-deep isolation recesses of insulating support at the alternate two electrode shell fragments that separate that are provided with on the brush body, is not communicated with, thereby the battery no power is to motor with two battery lead plates, then motor does not rotate.
