Abstract
An electric toothbrush comprises a toothbrush body (9) and a toothbrush handle (8) movably buckled with the top end of the toothbrush body (9), wherein the end part of the toothbrush handle (8) is movably connected with a rotary toothbrush head (7), a deflector rod component (6) used for transmitting power is arranged between a speed change gear set eccentric mechanism and the rotary toothbrush head (7), the middle section of the deflector rod component (6) is sleeved with a waterproof ring (4), and the waterproof ring (4) is fixed at the interface of the toothbrush body (9) and the toothbrush handle (8); the motor (1) in the inner cavity of the toothbrush body (9) drives the eccentric mechanism of the speed change gear set to move, one end of the driving lever component (6) is stirred by the eccentric mechanism to enable the driving lever component (6) to swing left and right by taking the water-proof ring (4) as a fulcrum, and the other end of the driving lever component (6) pushes the rotary toothbrush head (7) to rotate in a forward and reverse reciprocating manner. The electric toothbrush has larger back and forth rotation angle of the rotary toothbrush head, thereby improving the tooth brushing efficiency.
Description
Technical field the present invention relates to daily electric toothbrush.
The electric toothbrush of background technology available technology adopting rotation, No. 5625916 patents as the U.S., the disclosed technical scheme of this patent is, be installed in the intravital motor of toothbrush shell and drive the rotating shaft rotation, the terminal part of countershaft is bent to form eccentric stiffener, promotes head toothbrushes with this eccentric stiffener and comes back rotation.Because the volume of electric toothbrush is generally not too large, therefore come the stroke of back rotation generally shorter by driving head toothbrushes with the in-plant eccentric stiffener of head toothbrushes, therefore the work efficiency of electric toothbrush is affected.
The summary of the invention the technical problem to be solved in the present invention provides a kind of simple and reliable for structure, head toothbrushes and rotates back and forth the bigger electric toothbrush of angle.
The present invention takes following technical scheme: design a kind of electric toothbrush, comprising: the change-speed gearing group on the motor of toothbrush body and inner chamber thereof and the motor power output shaft, and this change-speed gearing group is provided with eccentric stiffener; With the handle of toothbrush body top active buckle, the end of this handle and rotary toothbrush head flexibly connect; Also comprise: the driving lever assembly between change-speed gearing group eccentric stiffener and rotary toothbrush head in order to transferring power, stage casing socket one water proof ring of this driving lever assembly, this water proof ring is fixed on the seam of toothbrush body and handle; Described motor drives the eccentric mechanism movement of described change-speed gearing group, and it is that fulcrum swings with the water proof ring that the end that eccentric stiffener is stirred the driving lever assembly makes the driving lever assembly, and the other end of driving lever assembly promotes the forward and reverse reciprocal rotation of rotary toothbrush head.Because the total length of driving lever assembly is longer, fulcrum is positioned at the centre of driving lever assembly, so the clutch end of driving lever assembly can have swing by a relatively large margin, the also inevitable obviously increase of the stroke of the left-right rotation of the rotary toothbrush head that is driven by it.
Described driving lever assembly comprises slide bar and connecting rod, and slide bar has the bulb front end, and the back side of rotary toothbrush head is provided with opening chute backward, corrects before the bulb of described slide bar and drops in this chute; The hole internal fixation that inserts the leading section of connecting rod behind the centre bore of water proof ring is passed in the rear end of slide bar; The rearward end of connecting rod has a groove, and the driven gear of described change-speed gearing group is provided with eccentric shaft, and this eccentric shaft drops in the groove of connecting rod rearward end, makes the power from the change-speed gearing group be passed to connecting rod.
The center, the back side of described rotary toothbrush head is convexly equipped with a steel axle, this steel axle is nested in the locating hole of handle after passing the centre bore of a rotary sleeve together, after putting in place, socket is stuck in the draw-in groove on steel axle top, the rotary toothbrush head back side with an E shape meson, the rotary toothbrush head is draped is positioned on the handle, and can do forward and reverse rotation around the axle center of steel axle.This structure has realized that the rotary toothbrush head is connected with the rotary moveable of handle.
The zone, stage casing of described handle is implanted with bristles and constitutes the manual toothbrush head, head is provided with the locating hole that is used for fixing the rotary toothbrush head, tail end is provided with the location buckle that cooperates with toothbrush body top, handle is inserted on the cooperation position of toothbrush body along the axle center, be inserted into a buckle of back handle tail end and be stuck on one's body the toothbrush, its handle is fixed on one's body the toothbrush.Therefore, this electric toothbrush contains two head toothbrushes, and one is the manual toothbrush head identical with general toothbrush, and one is electric toothbrush head.This also is one of unique technique feature of the present invention.
There is a directed square column described connecting rod end, and this square column makes the swing of driving lever assembly be limited at the certain level face.
For making water proof ring not produce displacement, described water proof ring is provided with the directed square opening of the bar that is connected and cooperates the directed half slot of brush body.For guaranteeing the swing of driving lever assembly steadily, described water proof ring also has appropriate elasticity.
Compared with prior art, electric toothbrush of the present invention has following beneficial effect: simple in structure, reliable, have simultaneously manually and electric toothbrush head, and the angle that electric toothbrush head rotates back and forth is bigger, thereby has improved brushing efficiency.
