Abstract
The utility model discloses a transmission assembly of an electric toothbrush, which comprises a driving wheel and a driven wheel. The driving wheel and the driven wheel are vertically meshed with each other. The transmission assembly is characterized in that: a fixed bulge and a fixed brush head bulge are arranged on the driven wheel, the fixed brush head bulge is directly matched with a brush head, and the fixed bulge is in sliding contact with a cylindrical hole at the bottom part of a brush rod head part. A cylindrical driving wheel extending end is arranged at the end part of the driving wheel along the direction of wheel teeth. A hole matched between the driving wheel and a transmission shaft is a D-type one. The driving wheel of the transmission assembly is a straight-tooth conical sector gear or an oblique-tooth conical sector gear or a curved-tooth conical sector gear; correspondingly, the driven wheel is also a straight-tooth conical sector gear or an oblique-tooth conical sector gear or a curved-tooth conical sector gear. The transmission assembly solves the problems that the electric toothbrush cannot achieve the effect of vertically rotating at 360 DEG, is instable for use and causes high noise.
Description
Technical field
This utility model relates to a kind of toothbrush, a kind of specifically electric toothbrush transmission component.
Background technology
Toothbrush is indispensable articles for use in people's daily life, and the drive disk assembly of present being seen electric toothbrush head often adopts parts such as fork or screw rod, these modular construction complexity, it is lower that its kinetic energy transfers rate, the waste energy, and not steady in the rotation process, and noise is bigger.
The utility model content
The purpose of this utility model provides a kind of electric toothbrush transmission component, solves to use the traditional toothbrush inconvenience at present and use the electric toothbrush head operation not steady, the problem that noise is bigger.
This utility model solves its technical problem and says that the technical scheme that adopts is:
The electric toothbrush transmission component, the drivewheel and the driven pulley that comprise two mutual Vertical Meshing, have fixed lobe on the driven pulley and reach fixedly brush projection, this is the direct and brush coupling of brush projection fixedly, the cylindrical hole sliding-contact of fixed lobe and brush holder support brushhead portion bottom:
Described drivewheel has cylinder drivewheel elongation end in its end along the cog direction.
The hole of described drivewheel and power transmission shaft coupling is " D " type hole.
The drivewheel of described electric toothbrush transmission component is straight-tooth circular cone sector gear or helical teeth circular cone sector gear or curve tooth circular cone sector gear or passes through gear; The driven pulley correspondence also be straight-tooth circular cone sector gear or helical teeth circular cone sector gear or curve tooth circular cone sector gear or pass through gear.
The beneficial effects of the utility model are, owing to use taper transmission gear means transmission brush, so stable drive, make that brush can be with 60 degree rotations, and drivewheel has extended certain length vertically in this taper driving gear set, convenient like this installation, itself and power transmission shaft adopt " D " type borehole jack to connect, so the phenomenon that power transmission shaft and drivewheel skid can not take place in transmission process.Driven pulley utilizes the projection of himself to replace the little axle of one of other use to be connected with brush, thereby has reduced the use of parts, has reduced the production technology of integral product, has reduced cost.

1. electric toothbrush transmission components among the figure, 11. drivewheels, 111. cylinder drivewheel elongation ends, 12. driven pulleys, 121. fixed lobes, 122. fixing brush projectioies.
The specific embodiment
Please refer to Fig. 1 to Fig. 2, the drivewheel 11 of electric toothbrush transmission component 1 is the circular cone sector gear, and it can adopt straight-tooth, also can adopt helical teeth even can adopt the curve tooth; End at this gear has a cylinder drivewheel elongation end 111 along the cog direction, so conveniently driven pulley 12 is installed on the drive link, initiatively gear teeth transmission is more steady in order to make the drive link machine, the hole of drivewheel and drive link coupling can be become " D " type hole.
Please refer to Fig. 3 and Fig. 4, the driven pulley 12 of electric toothbrush transmission component 1 has fixedly brush projection 122 of a fixed lobe 121 and; This driven pulley 12 adopts fixedly brush projection 122 direct and brush couplings, thereby has avoided existing electric toothbrush to adopt little axle that brush is fixedlyed connected with driven pulley, reduced the use of parts, and transmission is more steady.This driven pulley 12 promptly can adopt the external screw thread fixed form to fixedly connected with brush, also can adopt the female thread connected mode fixedly connected.
Please refer to Fig. 5 and Fig. 6, the drivewheel 11 of electric toothbrush transmission component 1 rotates under the drive of drive link, and then drives driven pulley 12 rotations, reaches and makes bristle realize unidirectional rotation thereby drive the rotation of bristle fixed mount simultaneously.
The drivewheel of electric toothbrush transmission component may be selected to be straight-tooth circular cone sector gear or helical teeth circular cone sector gear or curve tooth circular cone sector gear or hat tooth circular cone sector gear in the present embodiment; The driven pulley correspondence also be straight-tooth circular cone sector gear or helical teeth circular cone sector gear or curve tooth circular cone sector gear or hat tooth circular cone sector gear.
Claims (4)
