Description
Technical field
The present invention relates to technical field of motors, and in particular to a kind of sound wave motor and its electric toothbrush.
Background technique
With the continuous improvement of people's living standards, electric toothbrush is realized more preferably and more due to that can substitute traditional toothbrush
Convenient and fast toothbrushing effect, is more and more widely used.
Electric toothbrush generallys use the high-speed motion of novel high-frequency motor, drives head toothbrushes or so high speed swinging, generates machine
Tool vibration, vibration frequency is consistent or close with frequency of sound wave, to reach superpower cleaning effect.It is existing to use high-frequency electric machines
Electric toothbrush electric machine in function be it is single, be unable to satisfy the multi-functional needs of electric toothbrush.
Summary of the invention
The object of the present invention is to provide a kind of sound wave motor, one in above-mentioned technical problem or multiple can solve.
It is a further object to provide a kind of electric toothbrushes using the above sound wave motor.
In order to achieve the above object, technical solution proposed by the present invention is as follows:
Sound wave motor, including sound wave motor body and transmission shaft, the transmission shaft are hollow shaft, and transmission shaft passes through the electricity
The upper and lower ends of machine body interior, transmission shaft are respectively arranged with external connection end.
In the present invention by the transmission shaft in motor, it is set as hollow shaft, makes liquid tooth paste (or simple liquid) can be with
From intermediate conduit flow, the structure of entire electric toothbrush is simplified, and when liquid tooth paste passes through this motor, also not
It will affect the use of motor itself.
Additionally as sound wave motor body structure it is not limited here, it is public to can be disposable type on the market or patent
Open the sound wave motor in document;Solid shafting in the above sound wave motor body is replaced with into the hollow shaft in the present invention, and
Connecting pin (be tightly connected end) is arranged in hollow shaft both ends, so that it may so that motor itself is realized multi-functional, both can have sound wave electricity
The function of machine itself, while also having the function of circulating liquid.
It is further: to be provided with multiple annular grooves as connecting pin in an end of transmission shaft.In the both ends of transmission shaft
At least one end structure for being set as annular groove, used herein is multiple annular grooves as connecting pin, passes through continuous ring
Connected in star connection, realization is multi-sealed, is completely embedded, effectively prevent revealing.
The structure of connecting pin is adjusted according to the component difference of connection for external connection end, it is not limited here concrete form.
It is further: the sound wave motor body include shell, stator module, rotor assembly, transmission shaft, first bearing,

I-shaped slot, the second I-shaped slot are opposite with the first I-shaped slot;Auricle is set on second open tubular column, is opened on auricle
If metallic channel, the second plastic cement fastener is integrated injection molding.
The second plastic cement fastener is that integrated through injection molding is formed, and iron core group (I-shaped silicon steel sheet group) is cooperated to have herein
Slot, slot are limited silicon steel sheet group, and the first plastic cement fastener and iron core group are fixed together by coiled wire-wound coil group;It is hollow
Part for use by;It is provided with metallic channel on auricle, after the connector lug pitch of the laps of winding coil, is positioned by the metallic channel,
Then end cap is then passed through to stretch out except entire motor.
Further: the motor casing is plastic housing.Anti-electric, use is safer.
Electric toothbrush, including sound wave motor described in any of the above one.Using the toothbrush of this sound wave motor, structure is more
It simplifies, makes the overall volume of electric toothbrush smaller directly through motor without additional increase toothpaste currency structure, and
More rapidly, manufacturing cost is low for assembly;In use, it is stretched out due to the power connection mechanism of motor from motor, external shape, therefore
Without having to worry about motor inner inlet, use is more safe and reliable.
The solution have the advantages that:
The configuration of the present invention is simple, use is safe, and motor overall structure is simplified, and (oil film high frequency is led with existing high-frequency electric machines
Electricity-motor bearings is powered) it compares, there is functional diversity;Using safer, motor is not afraid of chance water;And winding coil shape
At circle damping make Oscillation Amplitude smaller;Assembly is rapider while production efficiency improves, and is more favorable for manufacturing.
