As shown in Figures 3 and 4, the other end of drive shaft 20 is connected with circular gear 30, band moving gear
30 rotations.Drive shaft 20 is coordinated with gear 30 using interference fit or gap to be fixed together.Tooth
Wheel 30 can use plastics, metal, powder injection (MIM), the material such as powder metallurgy.
Fig. 5 is the gear of embodiment one and the structural scheme of mechanism of the second rotating disk.
As shown in Figures 3 and 5, the side of the second rotating disk 60 has second end face gear 61.Should
Face gear 61 is vertical with the central axis of gear 30；Both central shaft can intersect or
It is non-intersect, and then brush is planted the utilization space that hair part obtains maximum, both gears are mutually nibbled
Close.
Second rotating disk 60 also has circular bosses 62.The center of 62 and second rotating disk of circular bosses 60
Overlapping of axles.Positive inner ring bristle 96 is arranged on circular bosses 62, forms interior brush.
Back bristle 90 is arranged on opposite side, that is, the second rotating disk 60 back.In this reality
Apply in example, back bristle 90 is first arranged on brush board, brush board is being fixed on the second rotating disk 60
Back.Certainly, back bristle 90 can be arranged directly in the second rotating disk 60.
Back bristle 90 can be cleaned to soft tissue in oral cavity, such as：Tongue etc..Back bristle
90 can with normal bristles either using more soft high polymer material, such as elastic soft material bristle or
Friction particles.Material generally has silica gel, thermoplastic elastomer (TPE) TPE, expanded material etc..
Second rotating disk 60 rotates under the driving of gear 30.

Fig. 7 is the gear of embodiment one and the structural representation of rotating disk.
As shown in Figure 6 and Figure 7, the side of the first rotating disk 70 has first end face gear 71.
The face gear 71 is vertical, both intermeshings with the central axis of gear 30.First
Face gear 71 is relative with the surfaces of revolution of second end face gear 61 and the surfaces of revolution is parallel to each other.
First rotating disk 70 also has centre bore 72.Centre bore 72 is enclosed on circular bosses 62, and two
Person matches, that is, realizes that the first rotating disk and the second rotating disk are coaxial.
First rotating disk 70 rotates under the driving of gear 30 around circular bosses 62.Positive outer ring bristle
On the outside in 97 centrally disposed holes 72, outer brush is formed.
The number of teeth of the face gear of first rotating disk and the second rotating disk can be designed to identical or not
Together, and then make it that the speed of brush is identical or different, and then reach human body most comfortable state.
Gear 30 can be spur gear wheel or cylindric spiral gear.First rotating disk and the second rotating disk
Face gear can accordingly be done and coordinate according to the design of gear.
As shown in Fig. 2 cover plate 80 and shell 40 can using ultrasonic bond, radium-shine weldering, glue,
Thermofussion welding, hot plate welding.
Between first rotating disk 70 and the second rotating disk 60 provided with public mating surface or bearing and then
Reach that radial positioning is acted on.Between first rotating disk 70 and the second rotating disk 60 provided with step surface or
It is bearing, is cooperated with shell 40 and cover plate 80, and then reach the effect of axially position.
Frictional force during in order to reduce the first rotating disk 70 and the rotation of the second rotating disk 60, Ke Yi
Two set plane bearing between rotating disk and shell or cover plate so that rotating disk motion is more smooth.
Certainly, it is contemplated that the service life of toothbrush is general at 3 months or so, and integrated cost considers, also may be used
To be not provided with bearing, the using effect of toothbrush is not influenceed.
The linear velocity of brush can be set as 1500mm/s-3500mm/s (children)；
2500-6500mm/s (adult).Certain motor can have the rotating speed of multistage gear, be selected for user.
Bristle can use implanted, or injection molding, and bristle diameter is 3~5um.
The operation principle of Double-face rotating brush-finish toothbrush：
Brushhead portion is inside and outside two brushs of the first rotating disk and the formation of the second rotating disk, rotating disk
Face gear is provided with, the motion of motor is coordinated by the face gear of drive shaft and gear and rotating disk,
By the driving of gear, it may be such that two brushs can be with 360 ° of positive and negative rotations inside and outside front；Simultaneously
Back bristle synchronous rotary, cleans oral cavity.
Certainly, back bristle can also be divided into inner ring and outer ring, be separately positioned in two rotating disks,
So that back bristle can also 360 ° of positive and negative rotations.
Embodiment two
