Description
This utility model relates to a kind of electric toothbrush, particularly a kind of electronic rotary toothbrush.
At present, the general toothbrush that uses is the toothbrush of monolateral hairiness, and this toothbrush vertically uses very inconvenient, therefore user is laterally brushed teeth mostly, this is a kind of unscientific teeth brushing way, and the dirt of not only ensconcing the slot depths is easy-clear not, and has influenced tooth health to a certain extent; A kind of swing type electric toothbrush appearred on the market in modern several years, but because shortcomings such as its person's of existence amplitude of fluctuation is less, the easy damage of drive mechanism, result of use is undesirable.
The purpose of this utility model provides a kind of suitable electronic rotary toothbrush of vertically brushing teeth.
Task of the present utility model is to realize like this, this utility model comprises housing, head toothbrushes, axle, motor, power supply etc., wherein head toothbrushes is fixed on an end of axle, motor is fixed in the housing, it is characterized in that: the planetary gear deceleration device is housed between described motor and the axle, the power of motor reaches head toothbrushes by axle after the planetary gear deceleration device slows down, for the use of brushing teeth.
This utility model is novel, simple in structure, and user can vertically be brushed teeth easily, has overcome the shortcoming of traditional teeth brushing way, effectively removes the dirt of slot depths, reaches the effect of strong protecting teeth.
Now the utility model is described in further detail in conjunction with the accompanying drawings.
Fig. 1 is a structural representation of the present utility model.
This utility model comprises housing 1, head toothbrushes 2, axle 3, motor 4, power supply 5 etc., wherein head toothbrushes 2 is fixed on an end of axle 3, motor 4 is fixed in the housing 1, it is characterized in that: between described motor 4 and the axle 3 the planetary gear deceleration device is housed, the power of motor 4 reaches head toothbrushes 2 by axle 3 after the planetary gear deceleration device slows down.Described planetary gear deceleration device comprises centre wheel 6, planetary gear 7, ring gear 8, planetary wheel carrier 9, wherein centre wheel 6 and planetary gear 7 external toothings, engagement in planetary gear and the ring gear, centre wheel 6 is fixed on the output shaft of motor 4, and planetary wheel carrier 9 is fixed together with axle 3; Described planetary gear deceleration device can also constitute multiple-stage reduction unit by two groups or more gear, when the planetary gear deceleration device is that two-stage or two-stage are when above, connect by little axle 10 between at different levels, the planetary gear deceleration device shown in the present embodiment constitutes double reduction gear by two groups of gears exactly; On described head toothbrushes 2, have the outside radial bristle of 2 rows at least, be generally 4 rows that are " ten " font, or be 6 rows of " * " type; Outside head toothbrushes 2, also has brush cover 11, with the protection bristle; Two-direction switch 12 also is housed, with the rotating of control head toothbrushes on housing 1.
