Specific implementation mode
Invention is further described in detail with reference to the accompanying drawings and detailed description.
- Fig. 9 referring to Fig.1, a kind of electric tooth care appliance, i.e. electric toothbrush, including handle, brush head, reciprocating rotary favourable turn
Structure, the reciprocating rotating mechanism include silicon steel sheet 1, rotating member 2, detent mechanism.
There is the silicon steel sheet 1 pole 3, the pole 3 to be around with coil 4.
The rotating member 2 is connect with the detent mechanism, and the detent mechanism keeps about 2 rotating member fixed
Position and can circumferentially rotate, i.e., rotating member 2 is rotatable but can not move up and down.
The rotating member 2 is equipped with magnet 5, and the two poles of the earth of the magnet 5 are opposite with the pole of silicon steel sheet 3.It needs to refer to
Going out, rotating member described here is equipped with magnet, refers to setting rotating member, magnet is then arranged on rotating member, or
Magnet itself is rotating member, which is rotary.
The coil 4 is connect with the commutator for controlling electric current commutation.Electric toothbrush uses DC power supply, the commutation
Commutator common in the art, such as H-bridge drive circuit etc. can be used in device.
Brush for electric toothbrush is sleeved on the rotating member 2.
The pole 3 of silicon steel sheet generates magnetism after coil is powered, and the magnetic pole of pole end is the poles N or the poles S, and on rotating member
The two poles of the earth of magnet 5 are corresponding with 3 column of the pole of silicon steel sheet, according to identical charges repel each other the principle that there is a natural attraction between the sexes so that rotating member 2 is in magnet
Power of the place by two opposite directions；Simultaneously because rotating member 2 is positioned up and down, therefore rotating member 2 can not be spun upside down, in Liang Chu
It can only be circumferentially rotated in the case of by opposite direction power, to realize the rotation of rotating member 2；After the electric current in coil 4 commutates,
2 stress of rotating member are reversed, to realize the reverse rotation of rotating member 2.2 reciprocating rotation of rotating member can drive brush head reciprocating rotary
It is dynamic.
In the present embodiment, the pole 3 tool there are two, two poles 3 are linked together in lower end, on two poles 3 around
If coil 4 be same coil（That is the line of winding is single line on two poles）And the circular direction on two poles is identical,
Current direction is identical when being powered to two poles, 3 coil, and the magnetic pole at this time on the two poles of the earth styletable face is also identical.The rotating member
There is magnet 5 corresponding with two poles 2, magnet to be distributed with two pole corresponding positions magnetic pole having the same, at this time magnet on 2
5 can be two pieces, two pieces of 5 magnetic pole having the same of magnet distributions（If it is the poles S that the front side of one block of magnet, which is on rear side of the poles N, another
It is also the poles S that the front side of block magnet, which is also on rear side of the poles N,；If it is the poles N that the front side of one block of magnet, which is on rear side of the poles S, another block of magnet
It is also the poles N that front side, which is also on rear side of the poles S,）The front side of magnet is that the poles S rear side is the poles N or front side is when either magnet uses one piece
It is the poles S on rear side of the poles N, due to being one block of magnet, therefore realizes being distributed with two pole corresponding positions magnetic pole having the same for magnet naturally.
After powered up, the current direction of the coil on two poles is identical to coil 4, therefore the polarity of two 3 upper ends of pole is identical,
Therefore two magnet 5 on rotating member（Or the both ends of one block of magnet）Impact direction it is also identical, to further be conducive to rotating member 2
Rotation.
In the present embodiment, the rotating member includes rotor plate 6, and the magnet 5 is set on the rotor plate 6, best
For the back side of rotor plate.It is of course also possible to be that magnet itself constitutes rotor plate, to realize what rotor plate was combined into one with magnet
Effect, this is also " magnet is set on rotor plate " in another meaning.The rotor plate 6 is equipped with axial drive link
7, the drive link 7 is fixed with the rotor plate 6.Between the column of the two poles of the earth, rotor plate 6 is located at two for the lower part of drive link 7
The top of pole.The brush head is sleeved on the top of the drive link 7.It is described when magnet and rotor plate are combined into one
Drive link is set on magnet, and the drive link is fixed with the magnet.The lower part of drive link 7 between the column of the two poles of the earth,
Rotor plate 6 is located at the top of two poles.The brush head is sleeved on the top of the drive link 7.
In the present embodiment, the detent mechanism includes upper positioning device, lower positioning device；The lower positioning device pair
The lower part of the rotating member carries out axially position, and the upper positioning device carries out axially position to the top of the rotating member.
Lower positioning device described in the present embodiment includes pedestal 8, and the pole 3 of the silicon steel sheet is inserted into the pedestal and positions,
Common positioning method is to open up to wear mouth on pedestal 8, and the pole 3 of silicon steel sheet is inserted to be positioned, and also may be used certainly
To be that other modes for example set card slot on pedestal, it is medium that silicon steel sheet is caught in card slot；The lower end of the drive link is equipped with elastic piece
11, the lower end of the elastic piece is inserted into the pedestal, so that the lower end of rotating member is positioned.The present embodiment midsole
Seat includes pedestal 9 and bottom cover 10, after there is on pedestal insertion groove, elastic piece 11 to be inserted into the insertion groove, then by bottom cover
10 cover in insertion groove, fixed by screw or rivet etc. between bottom cover 10 and pedestal 9, to reach the positioning of elastic piece 11.
Certain elastic piece 11 also can be used other and reach fixation with pedestal, such as elastic piece is inserted directly into pedestal and interference is matched therewith
It closes, pass through connector between elastic piece and pedestal（Such as screw, rivet etc.）The modes such as Nian Jie between connection, elastic piece and pedestal
The fixation of elastic piece.The effect of elastic piece is：It therefore will not be limited with elastic reaction due to it in 2 rotation process of rotating member
The rotation of rotating member processed, while its elastic reaction also assists in the reset of rotating member 2.The shape of 11 generally use sheet metal of elastic component
Formula.
