Application number a kind of mechanical toothbrush with two roll brush systems that has been the disclosure of the invention of CN94193923.5, it comprises a hands and the body of shape (1) and one is fixed on above-mentioned hands upper head (4), two adjacent, counter-rotational cylindrical brush (5 are housed in above-mentioned head (4), 5 '), the axis of above-mentioned brush is substantially parallel to each other.According to the present invention, each brush is by the flexible shaft (9 be arranged in head (4), 9 ') drive, and at least supported by corresponding bearing (16) in its most end, bearing is arranged on support member (10), and above-mentioned support member (10) makes two brushes can do the motion be separated toward each other, then, utilize recovery Effects, can also ensure that they are bringing together.This toothbrush can solve the uncomfortable sex chromosome mosaicism that conventional power toothbrush dither produces, but, because the front end of cylindrical brush is by bearings, bearing and support member occupy certain space, make the bristle of cylindrical brush cannot brush the wisdom tooth of rearmost end, especially cannot brush the lateral surface of the wisdom tooth of rearmost end, and, the easy breed bacteria of residue in bearing and support member, makes the head of toothbrush be difficult to cleaning.
[summary of the invention]
The technical problems to be solved in the utility model is to provide a kind of Dual-shaft electric toothbrush be convenient to brush part and cleaned, can brush wisdom tooth easily.
In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is, a kind of Dual-shaft electric toothbrush, comprise housing as handle adjacent with two, the brush that reversely rotates, brush comprises brush and brush axle, and brush axle is driven by the motor installed in the housing; The brush axle extend in housing is supported by the bearing in housing, the brush cantilever of brush.
Above-described Dual-shaft electric toothbrush, brush is pre-small post-large spindle.
Above-described Dual-shaft electric toothbrush, brush comprises the head that silica gel makes and the bristle being planted in head, and the head that silica gel makes is fixed on brush axle, and brush axle is elastic shaft.
Above-described Dual-shaft electric toothbrush, comprises baffle plate, and baffle arrangement is in the side of two brushes; There is a gib head rear end of baffle plate, and there is a clamping joint at rear portion, the rear portion of baffle plate and housing clamping, front end cantilever.
Above-described Dual-shaft electric toothbrush, the height of baffle plate is greater than the wheelbase of two brushes, is less than the height overall of two brushes.
Above-described Dual-shaft electric toothbrush, baffle plate outer surface is cambered surface, and baffle plate front end tilts to the axis direction of brush
Above-described Dual-shaft electric toothbrush, comprises two travelling gears and two shaft coupling sleeves, and the rear end of brush brush axle is connected with the front spindle nose of travelling gear by shaft coupling sleeve, and the front spindle nose of travelling gear is supported by the second bearing in housing; First travelling gear engages with the second travelling gear, and the first travelling gear is connected with motor shaft, and the rear spindle nose of the second travelling gear is supported by the 3rd bearing in housing.
Above-described Dual-shaft electric toothbrush, housing comprises handle and block, and motor, two travelling gears, the second bearing and the 3rd bearing arrangements are in handle; The bearing arrangement of supporting brush brush axle is in block, and brush brush axle is through block and shaft coupling sleeve connection; The rear end of block and the front end clamping of handle.
The brush cantilever of this utility model electric toothbrush brush, front end does not have obstacle, can brush the wisdom tooth of inner terminal in oral cavity easily; Brush is convenient to clean, and can prevent bacteria breed.
[accompanying drawing explanation]
Below in conjunction with the drawings and specific embodiments, this utility model is described in further detail.
Fig. 1 is the front view of this utility model embodiment Dual-shaft electric toothbrush.
Fig. 2 is the top view of this utility model embodiment Dual-shaft electric toothbrush.
Fig. 3 is that A in Fig. 1 is to profile.
[detailed description of the invention]
The structure of this utility model embodiment Dual-shaft electric toothbrush as shown in Figure 1 to Figure 3, comprise as the housing 1 of handle, baffle plate 3 adjacent with two, the brush 2 that reversely rotates.
Housing 1 comprises handle 101 and block 102, the block rear end of 102 and the front end clamping of handle 101.
The control circuit of electric toothbrush, battery, motor 3 and two travelling gears are arranged in the inner chamber of handle.
Two travelling gears are respectively driving gear 8 and driven gear 9, and driving gear 8 and driven gear 9 engage, and initiatively travelling gear 8 is directly connected with the main shaft of motor 3.
Two shaft coupling sleeves 7 are enclosed within the front spindle nose of driving gear 8 and driven gear 9 respectively, and the front spindle nose of driving gear 8 is supported by the bearing 103 in handle.
The front spindle nose of driven gear 9 is supported by the bearing 104 in handle, and rear spindle nose is supported by the bearing 105 in handle.
Brush 2 comprises brush 201 and brush axle 202, and shaft coupling sleeve 7 is inserted through the bearing 106 in block 102 in the rear end of brush brush axle 202, is connected with spindle nose before travelling gear by shaft coupling sleeve 7; Driven by the motor 3 be arranged in handle 101, realize reversely rotating by gears meshing between two brush axles 202.The front end of brush 201 does not have support, in cantilever position.
Because wisdom tooth is positioned at the rear portion in oral cavity, narrow space, brush 201 is pre-small post-large spindle, is convenient to each position that brush 201 can brush wisdom tooth.
