The specific embodiment
Below in conjunction with the drawings and specific embodiments, this utility model is described in further detail.
As shown in Figure 1 to Figure 3, a kind of electric toothbrush, comprises handle and head toothbrushes 10, is provided with motor 2 in handle, comprises the eccentric 4 on the output shaft 3 that is fixed on motor 2 on motor 2.On motor 2, be also provided with bulge-structure, bulge-structure comprises anastomotic part 51 and protrusion 52, at motor 2 overcoats, there is a shell 6, shell 6 tops are provided with a power transmission shaft 93, shell 6 inwalls are provided with the sunk structure 7 for inserting for described protrusion 52, and power transmission shaft 93 is fixedly connected with head toothbrushes 10 by a connection piece 9.
Bulge-structure is located on an inner support frame 8, and inner support frame 8 is fixed on motor 2 surfaces.
Sunk structure 7 is one to be arranged on the strip groove on shell 6 inwalls.Top at strip groove is also provided with spacing preiection 71.Correspondingly, protrusion 52 is axial strip projected parts thing.The annular projection of anastomotic part 51 for contacting with the inwall of shell 6.
Connector 9 comprises shell connecting portion 90 and toothbrush connecting portion 91, and shell connecting portion 90 comprises inwall, and its inwall is provided with female thread, and shell 6 upper ends are provided with external screw thread, and shell is threaded with shell connecting portion 90; Toothbrush connecting portion 91 is provided with the cavity coordinating with power transmission shaft 93, and its inside is provided with for clamping the shell fragment of the arc of power transmission shaft 93; Head toothbrushes 10 comprises brush holder support 100, and brush holder support 100 bottoms are provided with cavity, and toothbrush connecting portion 91 inserts in cavity and is connected with brush holder support 100.When power transmission shaft 93 inserts cavity, shell fragment inwardly clamps power transmission shaft 93, and the interface arrangment at power transmission shaft 93 tops is striped or ledge structure, can make the more firm in succession of power transmission shaft 93 and toothbrush connecting portion 91.
