Description
Technical field
The present invention relates to electric toothbrush, and in particular to the rotating speed control of electric toothbrush micromachine and changing for brushing mode
Into.
Background technology
Electric toothbrush is the new product occurred recent years, with its remarkable cleaning effect and to the massage effect of gum
A revolution of oral hygiene is known as, has become a kind of indispensable daily necessities in developed countries such as America and Europes.In state
Interior, with the lifting that the raising of living standards of the people and oral health are realized, the use of electric toothbrush is also increasingly popularized.Increasingly
The technology upgrading of the demand driving Liao Ge manufacturers of growth and product are perfect, the electric toothbrush of various functions occur, but pass through tune
Look into and analyze the existing product of in the market, it was found that following problem：
1. in existing electric toothbrush, the front and rear change of rotating speed of micromachine is bigger, corresponding electric toothbrush vibration frequency
Rate also just differs bigger：After battery is just fully charged, electricity foot, voltage is high, higher than the rated voltage of micromachine, micromachine
Rotating speed it is higher, feel under the weather when not only brushing teeth, or even have certain damage to gum；When battery capacity exhausts soon, voltage
Low, less than the rated voltage of micromachine, the rotating speed of micromachine is relatively low, is unable to reach expected cleaning effect.
2. the cleaning effect of electric toothbrush the experiment proved that, have compared with toothbrushes and significantly lifted, but most people
Still remain the custom brushed teeth using toothbrushes when in use, brushing time is too short, and can not take into account all teeth,
It has been omitted that, toothbrushing effect is had a greatly reduced quality, the effect of electric toothbrush can not be given full play to.
The content of the invention
To solve problem above, the present invention provides a kind of rotary electric toothbrush, and can ensure outside electric toothbrush
See, function and service life are not affected.
In order to achieve the above object, the technical solution adopted by the present invention is as follows：A kind of rotary electric toothbrush, its feature exist
In：Including toothbrush handle, brush head, micromachine, battery, circuit board and switch button, there are light transmission piece and bottom cover, the sealing of O shapes
Circle, sealing-plug；The brush head is fixed on the toothbrush handle top, passes through transmission device and the Miniature electric machine output shaft phase
Even, micromachine driving brush does swinging rotation；The micromachine, battery and circuit board are fixed in the toothbrush handle
In fixing device in portion's cavity；The switch button is arranged on the outer casing frontispiece of toothbrush handle, the top of close toothbrush handle,
And with the control circuit power button position face welded on the circuit board；The circuit board further comprises cpu control circuit,
Setting for the rotating speed and brushing mode that control micromachine.
Further：
The toothbrush handle is arc shape；There is the striped of wave-like at the toothbrush handle back side；The toothbrush handle
Outer surface high polish；The switch button, using ebonite as profile, injects flexible glue aftershaping；The toothbrush handle is the bottom of close to
End is provided with light transmission piece, and does frosted processing, the light transmission device as prompting function；The brush head can facilitate dismounting to replace
Change；The toothbrush handle bottom and the bottom cover flexible clamping for adding O-ring seals；The bottom cover back side is provided with charging hole, charging hole
Sealed with sealing-plug, the sealing-plug uses food grade silicon rubber.
Further：
The present invention is using the rotating speed of pulse width modulating technology control micromachine, and described micromachine one end and battery are just
Pole is electrically connected, and the other end is grounded by being used as 1 triode that switching tube uses, the ON/OFF control terminal and CPU of switching tube
The output terminal of control circuit is electrically connected, break-make (the high electricity of the square wave controlling switch pipe of cpu control circuit output pulse width modulation
Turned on during position, when low potential turns off), when cell voltage is higher, reduce duty cycle (high potential duration and the whole side of square wave
The ratio of wave period), the ON time of switching tube is reduced, and eliminates influence of the cell voltage to micromachine rotating speed；Cell voltage
During reduction, opposite operation is performed, it is ensured that the driving voltage of micromachine is approached with the rated voltage of micromachine all the time, so that
During the whole use of electric toothbrush, micromachine rotation speed change is not too large, and vibration frequency is relatively fixed.
The present invention uses 4 sections of timing brushing modes：Oral cavity is divided into 4 regions, each region corresponds to when brushing teeth of fixation
Between, after previous region has been brushed, toothbrush vibration has of short duration pause, prompts user to be moved to subsequent region, has brushed whole areas
Toothbrush is automatically closed behind domain.
The present invention, is controlled the whole process of brushing teeth using 1 button, has broken away from the model selection of redundancy, operation is more
To be simple and efficient.
Brief description of the drawings
Attached drawing described herein is used for providing a further understanding of the present invention, forms the part of the application, not
Inappropriate limitation of the present invention is formed, in the accompanying drawings：
Fig. 1 is structure diagram of the embodiment of the present invention.
Mark 1 is toothbrush handle, and mark 2 is brush head, and mark 3 is motor, and mark 4 is battery, and mark 5 is circuit board, mark
Note 6 is light emitting diode, and mark 7 is light transmission piece, and mark 8 is bottom cover, and mark 9 is O-ring seals, and mark 10 is sealing-plug, mark
