The specific embodiment
Below in conjunction with the drawings and specific embodiments in detail this utility model is described in detail:
See in appearance that referring to Fig. 1 this utility model electric toothbrush comprises head toothbrushes 1 and brush holder box 2 two parts, brush holder box 2 is the box body of hollow, front end has handle head 21, handle head 21 is a round bearing, and circle centre position is established recess 22, is center circle groove 23 and the protruding button bit 24 that distribute gradually with the recess; Head toothbrushes 1 is a movable member, in the head toothbrushes lower middle position, one-body moldedly establish a core 11, the center recess 22 of these core 11 corresponding handle head 21, be that corresponding described groove 23 in center and protruding button bit 24 distribute gradually and one enclose protruding button bit 13 and groove 14 in addition with axle core 11, groove 23 and button bit 13 corresponding fastenings, groove 14 and button bit 24 corresponding fastenings, head toothbrushes 1 and brush holder box 2 can be by this core 11 and recess 22 and groove 23, button bit 24 and button bit 13, groove 14 butts.When motor operates in the brush holder box 2, drive head toothbrushes 1 by this core 11 and rotate.
In this utility model, the shape of brush holder box 2 can be adjusted with hobby, can be for columned, also can be for long and flat, or other shape that makes things convenient for hands to grip.
And brush holder box 2 front end handle head 21, it also is cylindric being generally cylindric, corresponding head toothbrushes 1.
Fig. 2, Fig. 3 have shown being connected between drive link 3 and two locating pieces.Drive link 3 is a cylindrical metal bar, and locating piece A, B can be the plastic cement piece, and its height should equate with brush holder box 2 inner chamber height.Locating piece 41,51 is socketed on the drive link 3.Locating piece 41,51 can be square or cylindrical piece, changes according to brush holder box 2 cavity shapes, and the locating piece 41,51 shown in the figure is cylindric, at the center of locating piece 41,51, offers through hole 45, and for cooperating the cross sectional shape of drive link 3, through hole 45 is a flat-shaped hole.
Locating piece 41 is established projection 43 near a side of locating pieces 51, makes between the locating piece 41,51 and leaves the room, lowers friction when drive link 3 is rotated, and can also inject lubricant between locating piece 41,51.The position and the quantity of the projection 43 on the locating piece 41 are not particularly limited, projection 43 size and highly yet do not do special restriction.
For increasing the friction between locating piece 51 and brush holder box 2 internal chamber walls, establish raised line 53 on locating piece 51 surfaces, raised line 53 is the compressing internal chamber wall closely, the pressure between reinforcement and the internal chamber wall.Raised line 53 can be many, is equally distributed four in this example, and raised line 53 also can be set as protruding grain, is evenly distributed on locating piece 51 surfaces.
Being connected between drive link 3 and the drive rod joint 6 sees also Fig. 3.Afterbody at cylindrical drive link 3, impartial projection 31 about cylinder symmetric position pressure is made as, the inside pipe casing of drive rod joint 6, corresponding projection 31, narrow groove 61 is set, and during drive rod joint 6 socket drive links 3, projection 31 supports in the narrow groove 61, make between drive link 3 and the drive rod joint 6 firmly to be connected, can not become flexible; The steadiness that is connected between projection 31 and 61 combineds effect of narrow groove, drive link 3 and drive rod joint 6 is strengthened.
Behind said structure and annexation assembling drive link 3, again with drive link 3 with conventional method brush holder box 2 inner chambers of packing into, head toothbrushes 1 also installs on the brush holder box 2, then forms the electric toothbrush of original utility model, referring to Fig. 4.
