Detailed description of the invention
With embodiment, technical scheme is illustrated below in conjunction with the accompanying drawings.
As shown in Figure 1 and Figure 2, a kind of electric toothbrush head of the present invention, including brush holder support 1, drive rod 2 and turn
Dynamic brush 8, forms receiving chamber 12 in described brush holder support 1, brush holder support 1 one end forms installation cavity 11, installation cavity 11 and receiving chamber 12
Connection is arranged, and described drive rod 2 is rotationally arranged in receiving chamber 12, the described rotation brush 8 mounting head by its lower end
81 are rotationally arranged in installation cavity 11, interleave axle 6 in described installation cavity 11 in being fixed with, right bottom described mounting head 81
Should be provided with jack 84, described in interleave axle 6 and stretch in jack 84, said structure constitutes agent structure of the present invention.
As the primary object of the present invention, described drive rod 2 front end is sequentially provided with bending section 22 and connecting portion 23, described
Mounting head 81 sidewall is provided with holding tank 82, and described connecting portion 23 is connected with wear-resisting rotating shaft 5, and described wear-resisting rotating shaft 5 is inserted
Matched in clearance is formed with holding tank 82 in being located at holding tank 82.
During use, motor (not shown) drive rod 2 is driven to rotate, because described drive rod 2 front end is provided with bending
Portion 22, when drive rod 2 rotates, due to the setting of bending section 22, makes wear-resisting rotating shaft 5 produce eccentric rotary, thus to holding tank
The two side of 82 forms extruding, finally make rotation brush 8 within the specific limits by interleave left rotation and right rotation centered by axle 6.This
Bright structure is arranged rationally, because wear-resisting rotating shaft 5 is stretched in holding tank 82, and rotates brush 8 rotational angle limit, wear-resisting rotating shaft 5
It is not easy to come off from holding tank 82, drastically increases the operation stability of product.It addition, wear-resisting rotating shaft 5 extrudes appearance in radian
Receive two walls of groove 82, rather than two walls of direct collision holding tank 82, therefore significantly reduce noise.
It is provided with damping spring 7 between bottom described mounting head 81 bottom and installation cavity 11, rotation brush 8 can be effectively reduced
Vibrations during motion.Preferably, damping spring 7 two ends can be individually fixed in bottom mounting head 81 bottom and installation cavity 11,
So, not only it is effectively increased the globality of product, and, damping spring 7 provides restoring force when rotating brush 8 rotary motion,
It is beneficial to rotate brush 8 rotary motion.
On described drive rod 2, front end forms installation position 21 near the position of bending section 21, and described installation position 21 is provided with
Limit shaft sleeve 3, on the most described drive rod 2, end is provided with rotary shaft positioning sleeve 4.So arrange, limit shaft sleeve 3 and rotary shaft
Positioning sleeve 4 lays respectively at the two ends of drive rod 2, effectively limits drive rod 2 and swings the most back and forth, i.e. drive rod 2
Can rotate, and can not swing, drastically increase stationarity during production run.
Interleave axle 6 in described and be provided with slotting axle axle sleeve 10, it should be noted that described slotting axle axle sleeve 10 typically uses wear-resisting
Lubricious material is made, and is so conducive to inserting axle axle sleeve 10 and effectively coordinates with jack 84 and realize low friction rotation, reduces further
Noise, improves product quality.
Described mounting head 81 sidewall is provided with locating slot 83, and fixing pin 9 one end is fixed on brush holder support 1, and the other end stretches into
In locating slot 83, the setting of described fixing pin 9, rotation brush 8 can be limited and move up and down when motion, improve product further
The stationarity of product.
Described wear-resisting rotating shaft 5 front end forms insertion section 51, and described wear-resisting rotating shaft 5 is by insertion section 51 and holding tank 82 shape
Becoming matched in clearance, described insertion section 51 diameter is less than the diameter of wear-resisting rotating shaft 5 body, and being thus inserted into portion 51 more has with holding tank 82
It is beneficial to coordinate.
Described wear-resisting rotating shaft 5 forms interference fit by connecting hole 52 with connecting portion 23 and is connected.Described wear-resisting rotating shaft 5 is tight
Being matched with the front end of drive rod 2, stability is higher.
The above is only the better embodiment of the present invention, thus all according to the structure described in present patent application scope,
The equivalence that feature and principle are done changes or modifies, in the range of being all included in present patent application.
