Detailed description of the invention

Below in conjunction with the drawings and specific embodiments, this utility model and Advantageous Effects thereof are described in detail, but detailed description of the invention of the present utility model is not limited to this.

In one embodiment, toothbrush has rotate head and cervical region, and bristle can around the cervical region 360 degree rotation of toothbrush.The actuating device (as gear) being connected to driving wheel makes the head of toothbrush rotate in the mode of circular motion.When it is flatly placed near tooth, head with circumference and/or the mode that rotates towards or away from teeth training, thus imitate the motion of the wrist of the user of brushing teeth.

According to an aspect of the instruction of some embodiments, this utility model provides a kind of electric toothbrush, comprises the housing of Axis Extension along the longitudinal; Bristle shaft assembly, comprises and is arranged at described enclosure interior and along the axle portion that described longitudinal axis extends, is arranged at described hull outside and has multiple head extending the surrounding in described axle portion and the bristle with described longitudinal axis orthogonal; And being arranged at the electric control mechanism of described enclosure interior, described electric control mechanism controls described bristle shaft assembly and rotates around described longitudinal axis.

Clear in order to make technology disclosed in embodiment more understand, now describe in conjunction with following accompanying drawing and be described.

Refer to Fig. 1 and Fig. 2, Fig. 1 shows the exploded view of the toothbrush of an embodiment of the present utility model, and Fig. 2 shows the internal view of the handle of an embodiment of the present utility model.As seen from the figure: bristle axle 2 extends along the longitudinal axis 30 of toothbrush, and ends at the close end of bristle 1, bristle 360 degree around the whole periphery of bristle axle 2, thus forms a bristle shaft assembly, and further detailed description refers to Fig. 9 to Figure 10.

Bristle axle 2 is respectively by adapter 3, the O-ring seals 4 being installed on bristle axle 2 end, O-ring seals 5 and be connected with transmission case 7 with transmission case (geared spur box) 7 adapters be connected 6.Transmission case 7 is connected with motor 8, and during use, motor 8 drives the rotation of bristle 1, as will be explained hereinafter.Motor 8 is connected with pcb board 10, and this pcb board 10 comprises activator switch 9 and direction switch 11.

Motor 8 is also connected with rechargeable battery 13 with pcb board 10, and rechargeable battery 13 is powered for motor 8 and pcb board 10, and rechargeable battery 13 is arranged between battery electroplax 12 and 14.Battery 13 is also electrically connected with mains transformer 15, and mains transformer 15 is connected with USB 16, toothbrush can be connected with external power source by USB 16, for battery 13 charges.

Refer to Fig. 3, Fig. 4 and Fig. 5 now, Fig. 3 shows the top view of the toothbrush of an embodiment of the present utility model, Fig. 4 shows the upward view of the toothbrush of an embodiment of the present utility model, and Fig. 5 shows the side view of the toothbrush of an embodiment of the present utility model.

The composition of toothbrush except bristle 1 and adapter 3, remainder be closed in comprise upper shell 19 and lower house 20 housing in.Fig. 5 shows each parts be arranged in lower house 20.Housing parts 19 and 20 is interconnected, and connected mode can adopt any one suitable mode, such as clamping, bonding, welding, brazing filler metal etc.The end of housing is sealed by waterproof cover 17, opens seal cover 17 and can contact USB 16, thus charge for battery 13.Switch cover 18 is made up of silicon in certain embodiments, and it is arranged at the inside of upper shell 19, and just arranges PCB 10, switch 9 and 11 and be positioned at the top of PCB 10, switch 9 and 11.

In use, user holds toothbrush, and make bristle 1 facing to tooth, so, longitudinal axis 30 is horizontal, almost parallel with gingiva line.

Press activator switch 9, activate toothbrush with the first bristle rotary speed, again press activator switch 9 and bristle rotary speed is become the second bristle rotary speed, the second bristle rotary speed is greater than the first bristle rotary speed, and then press activator switch 9, make toothbrush deexcitation or closedown.Like this, user can determine according to his or her comfort level the rotary speed wanted by activator switch 9.

Press direction switch 11, when brush action, change the direction of rotation of bristle 1.Such as, if bristle 1 turns clockwise relative to longitudinal axis 30, so press direction switch 11 and bristle 1 can be made to be rotated counterclockwise relative to longitudinal axis 30.By using direction switch 11, user can guarantee that bristle rotates to tooth from gingiva, and so, the movement progress antibacterial of bristle and foul leave gingiva, no matter be that toothbrush uses on upper tooth or on lower tooth.Therefore, when brushing tooth, user presses direction switch 11 to guarantee that bristle is according to first direction rotary motion from top to bottom.Contrary, when brush lower tooth, user presses direction switch 11 to guarantee that bristle is according to the rotary motion from the bottom up of contrary direction.

Refer to Fig. 6 now, which show in an embodiment of the present utility model, visual angle is seen from the side, and bristle forms the number of assembling steps figure of a part for the bristle of toothbrush.Concrete, Fig. 6 A shows the side view of the flexible substrate 21 being essentially plane, and it is used as the matrix of the bristle of bristle 1.Substrate 21 can adopt any suitable material to make, and in certain embodiments, it is made up of flexible nylon.In certain embodiments, the thickness of substrate 21 is not more than 1mm.As can be seen from Fig. 6 B and Fig. 6 C: bristle 22 is connected with the plane orthogonal of substrate 21.Bristle 22 can be connected to substrate 21 by any suitable mode, and in certain embodiments, bristle 22 is connected to substrate 21 by the mode of ultrasonic bonding.In certain embodiments, the diameter of every root bristle, between 0.1mm to 0.01mm, in certain embodiments, is 0.05mm.In certain embodiments, the length of every root bristle, in 5mm to 10mm scope, in certain embodiments, is 8mm.The quantity being connected to the bristle 22 of substrate 21 is determined by the size of substrate 21.But, in certain embodiments, more than 10,000 bristle, more than 12,000 bristle, more than 15,000 bristle, or more than 18,000 bristle is used on a substrate 21.
