Description
Technical field
The utility model is related to a kind of rotary replacement electric toothbrush heads, belong to small household appliances product technical field.
Background technology
Electric toothbrush is the new product occurred in recent years, and a revolution of oral hygiene has been started in foreign countries.Electricity
Dynamic toothbrush makes brush head generate high-frequency vibration, toothpaste is resolved into subtle bubble by moment by the quick rotation or vibrations of electric core
Foam deeply cleans teeth space；At the same time, the trembling of bristle can promote the blood circulation in oral cavity, have massage effect to gingiva tissue.
But electric toothbrush at present has the following disadvantages：1st, it is brush head come the power that driving handle rotates by an axis
Rotation, the transmission of axis are not sufficiently stable, and rotational efficienty is low, so as to make brush head rotary force not big enough；2nd, pass through inner shaft and the biography of handle
Dynamic contact surface controls brush head pulling force, and tail-hood and handle interface lid are matched with being combined into pine, when under the high speed conditions of handle, brush head has
Jitter phenomenon, noise are excessive；3rd, brush head skids.These all cause inconvenience to user.
Utility model content
The utility model be for disadvantages mentioned above existing for current electric toothbrush head, provide it is a kind of rotatably replace it is electronic
Head toothbrushes overcome above-mentioned shortcoming.
Specifically, rotary replacement electric toothbrush head described in the utility model, is used for including being located at head toothbrushes end
Tail-hood, shell, inner shaft, balance staff, driving wheel, driven wheel, central shaft, brush head and the brush head spacer pin being connect with toothbrush handle, it is interior
Axle position is in enclosure and can be connected with each other with the handle transmission shaft of toothbrush handle, and balance staff both ends connect inner shaft and active respectively
Wheel, driving wheel, driven wheel and central shaft are located in brush head, and driving wheel drives driven wheel rotation, is provided with to limit on brush head
The brush head spacer pin that brush head is swung.
Further, the connecting pin of the balance staff and inner shaft, balance staff and driving wheel is equipped with annular knurl, and be interference fitted.
Further, the buckle for limiting is equipped between the tail-hood and shell.
Further, the tail-hood and handle interface lid elastic conjunction are pulled away from pulling force 0.9-3.5kgf.
Further, the gearratio of the driving wheel and driven wheel is 1:1.
Further, the ratcheting gap of the driving wheel and follower is 0.01-0.05mm.
Further, the pulling force of the inner shaft and handle transmission shaft is 0.1-0.2kgf.
Further, the brush head is equipped with bristle.
Further, the driven wheel and brush head are fitted close.
Rotary replacement electric toothbrush head described in the utility model, has the following advantages：
1. gear drive is steady, phenomena such as being not in shake at work, noise is small.Traditional toothbrush is overcome in this way
The big problem of noise.
2. transmission efficiency, clean effect is apparent.
3. the torsion of brush head is big.

Specific embodiment
Technical solution described in the utility model is illustrated below in conjunction with the drawings and specific embodiments, it is therefore an objective to be
The public more fully understands the technical solution rather than carries out arbitrary limitation to it.
As shown in Figs 1-4, rotary replacement electric toothbrush head described in the utility model is used including being located at head toothbrushes end
In the tail-hood 1, shell 2, inner shaft 3, balance staff 4, driving wheel 5, driven wheel 7, central shaft 6, brush head 9 and the brush head that are connect with toothbrush handle
Spacer pin 8, inner shaft 3 are located at 2 inside of shell and can be connected with each other with the handle transmission shaft of toothbrush handle, and 4 both ends of balance staff connect respectively
Inner shaft 3 and driving wheel 5 are connect, driving wheel 5, driven wheel 7 and central shaft 6 are located in brush head 9, and driving wheel 5 drives driven wheel 7 to rotate,
The brush head spacer pin 8 for limiting brush head swing is provided on brush head 9.Such as Fig. 4, the balance staff 4 and inner shaft 3, balance staff 4 and active
The connecting pin of wheel 5 is equipped with annular knurl 40, and is interference fitted, and the buckle 11 for limiting, institute are equipped between the tail-hood 1 and shell 2
It states tail-hood and handle interface lid elastic conjunction, is pulled away from pulling force 0.9-3.5kgf, the gearratio of the driving wheel and driven wheel is 1:
1, the ratcheting gap of the driving wheel and follower is 0.01-0.05mm, and the pulling force of the inner shaft and handle transmission shaft is 0.1-
