The specific embodiment

Below in conjunction with accompanying drawing this utility model is elaborated.It is to be made of brush 1, housing 2, switch 4, transmission component 3, motor 5, support 6, battery 7, tail-hood 8, tray 9; Housing 2 is made up of upper shell 21, lower house 22, anti-skidding projection 23, anti-skidding projection 23 is on housing 2, support 6, motor 5, transmission component 3 are arranged in housing 2, it on support 6 motor 5, switch 4 is contained on the support 6, and in the long waist shaped hole of upper shell 21, transmission component 3, form by coupling band 31, major axis 32, axle sleeve 34, obstruct axle sleeve 33, axle sleeve 34, obstruct axle sleeve 33 are contained in major axis 32, and place in the housing 2, coupling band 31 is connected the axle of motor 5 with major axis 32 1 ends, and major axis 32 other ends become

Shape; Tail-hood 8 is connected with housing 2, in battery 7 is arranged.Described lower house 22 1 ends have the convex cylindrical 221 of the smaller part cylinder of pruning, boss 222 is arranged on the convex cylindrical 221, on the boss 222 through hole is arranged, also have two through holes on the convex cylindrical 221, lower house 22 1 ends also have a pit, and a pit shape coupling on described tray 9 shapes and the lower house 22 has two feet 91 on the tray 9, be embedded in two through holes of convex cylindrical 221 of lower house 22 heads, the end face 92 of two feet 91 stretches out the end face of convex cylindrical 221.Brush body 11 1 ends of described brush 1 are bristles 18, there are convex cylindrical 12 and projection 13 in the other end, there is convex shoulder 14 convex cylindrical 12 ends, rectangular channel 15 is arranged on the convex cylindrical 12, projection 13 and brush body 11 junctions fluted 16, convex cylindrical 12 places the through hole of boss 222, and described groove 16 is to become to major axis 32 other ends The termination of shape is stretched into, and the end face 17 of brush body 11 contacts with the end face 92 of two feet 91; Also porose at housing 2, be the mounting hole 24 on lower house 22, be two.

During use, starting switch 4, motor 5 is connected with battery 7, the axle rotation of motor 5 at this moment, major axis 32 rotations that are connected with coupling band 31, the other end shape of major axis 32 is

Head also rotate, it embeds in the groove 16, brush 1 is laterally swung around the through-bore axis of boss 222, groove 16 place's projections 13 are when laterally swinging simultaneously, being subjected to convex cylindrical 221 is stopped by the end face that cuts, can not produce brush 1 around the rotation of the through-bore axis of boss 222,, brush 1 can be laterally swung because two foot faces 92 are close to the end face 17 of brush 1.In use if there is water to flow in the housing 2, because of the axle sleeve 33 of obstruct is arranged, water can inflow motor 5 in, at lower house 22 mounting hole 24 in addition, moisture content evaporated from mounting hole 24 or flow out.Anti-skidding projection 23 on the housing 2 makes the easier gripping this utility model of people.

After this utility model uses a period of time, the bristle 18 of brush 1 damages and maybe needs toothbrush is carried out disinfection, as long as extract brush 1, the new brush 1 or the brush 1 of sterilizing have a rectangular channel 15, have the convex cylindrical 12 of convex shoulder 14 to insert in the through hole of the boss 222 on the lower houses 22, at this moment have the end convex shoulder 14 of rectangular channel 15 to be extruded, and insert in the through hole of boss 222, after entering in the through hole, convex cylindrical 12 is restored, and brush 1 can not skidded off in the hole; Simultaneously The head of shape embeds in the groove 16.

The utlity model has simple in structurely, brush 1 is replaceable, can not skid during hand-held housing 2, can fine cleaning teeth, and because brush 1 can laterally swing in use, gingiva is had massage effect, the health care tooth.
