After upper, brush head 70 will start high-frequency vibration, realize the function and effect of cleaning and massaging oral.In the first driving pawl 31, second
During driving pawl 41 is mutually driven with flexible connector 50, since the column portion 51 of flexible connector 50 is in 31 He of the first driving pawl
In claw slot 53 between second driving pawl 41, can be covered to avoid first axle 30 and 40 axial line of the second axle sleeve not on the same line
Shi Buneng normally transmits torque;Multiple portions 52 of flexible connector 50 are respectively distributed to the first driving pawl 31 and the second driving pawl
In 41 adjacent pawl seam 54, the first driving pawl 31 pair second driving pawl 41 in rotation applies circumferential shearing force, but due to
The piece portion 52 of flexible connector 50 is located at the centre of force direction, therefore can float and transmit torque and damping, buffering;Meanwhile it brushing
First 70 can will shake in back transfer to the second axle sleeve 40 in vibrations, due between the first axle sleeve 30 and the second axle sleeve 40
First driving pawl 31 and the second driving pawl 41 are simultaneously not directly contacted with, but are connected by flexible connector 50, therefore are shaken not
It can be oppositely transmitted to from the second driving pawl 41 on first driving pawl 31, to be the output shaft that will not be transmitted to motor 10
On.Therefore, the acoustic toothbrush of the utility model can be transmitted on brush handle 60 in use to avoid vibrations, eliminate shake hand
And noise, user experience is promoted, while the axial line for working as the first axle sleeve 30 and the second axle sleeve 40 is crossed as not in same straight line
When angle, the radial forces to motor 10 can be eliminated, remain to normally transmit torque, motor 10 is made to keep normal work shape
State.
The above description is only a preferred embodiment of the present invention, therefore all according to described in the utility model patent application range
