Referring to fig. 1, the brushhead screw 100 is a detachable brushhead screw which is inserted onto a brushhead screw shaft 370 of the electric toothbrush control system 300, and the electric toothbrush control system 300 is completely enclosed by the electric toothbrush housing 200.

The electric toothbrush shell 200 is also provided with a plurality of indicator lamps 220, and the indicator lamps 220 are electrically connected with the battery 330, so that a user can know the current swinging speed grade of the bristles on the rotary rod 100 of the brush head part in real time and can remind whether the electric toothbrush is sufficient in power.

Referring to fig. 2, the electric toothbrush control system 300 includes an assembly housing 310, a control circuit board 320, a battery 330, a reduction motor 340, a sliding rod 350, a cam structure system 360, a brushhead swing rod rotating shaft 370, a brushhead swing rod rotating shaft bearing 380, a waterproof leather sheath 390, and a sensor 364 included in the cam structure system for precise return of the brushhead swing rod.

The assembly housing 310 is an assembly matrix of each component of the electric toothbrush control system 300, and the assembly housing 310 is internally provided with a control circuit board 320, a battery 330, a speed reducing motor 340, a sliding rod 350, a cam structure system 360, a brush head swing rod rotating shaft 370, a brush head swing rod rotating shaft bearing 380 and a waterproof leather sheath 390.

The battery 330 is electrically connected to the control circuit board 320, and the control circuit board 320 is electrically connected to the reduction motor 340.

Referring collectively to FIG. 3, the entire cam structure system 360 is disassembled for component assembly. The cam structure system 360 includes a cam member 361, a bearing 362, a motion trajectory conversion member 363, and a sensor 364. One end of a cam member 361 of the cam structure system 360 is sleeved on a motor head of the speed reducing motor 340, the other end of the cam member 361 is sleeved on a bearing 362, the bearing 362 is placed in a cavity of the motion trail conversion piece 363, the cavity is a long groove, and the bearing 362 can only move in the groove direction; the motion trail conversion piece 363 is connected with the assembling shell through the two sliding rods 350 and is erected in the cavity, the motion trail conversion piece 363 is not tightly connected with the two sliding rods 350, and the motion trail conversion piece 363 can move in the cavity along the two directions of the sliding rods 350 without friction. It should be noted that the direction of the slide bar 350 and the direction of the strip slot in the motion trail conversion piece 363 are 90 degrees to each other; now, the strip slot of the motion trajectory conversion member 363 is defined as X-axis, and the direction of the slide bar 350 of the fixed motion trajectory conversion member 363 is defined as Y-axis.

When the electric toothbrush is operated, the motor shaft of the gear motor 340 rotates to drive the bearing 362 sleeved on the cam member 361 to rotate together, and the whole bearing 362 moves along a circular line due to the eccentric action of the cam member 361. According to the laws of physics, any one force can be orthogonally decomposed into two forces perpendicular to each other, so that the regular circular motion of the bearing 362 can be decomposed into the reciprocating motion of the bearing 362 on the X-axis and the reciprocating motion of the motion trail conversion element 363 in the Y-axis direction. Wherein the X-axis direction is a direction of the elongated slot of the motion trail conversion element 363, so that the motion of the bearing 362 in the X-axis direction is invisible, and for the external world, only the reciprocating motion of the motion trail conversion element 363 in the direction of the sliding bar 350 can be seen.

One end of the rotating shaft 370 of the rotating rod of the brush head part is in a gear shape and is meshed with the gear of the rotating track converting piece 363 in a matching way, and the other end of the rotating shaft 370 of the rotating rod of the brush head part is in a flat shape and is assembled with the rotating rod 100 of the brush head part, therefore, the reciprocating motion of the rotating track converting piece 363 drives the rotating reciprocating motion of the rotating shaft 370 of the rotating rod of the brush head part to drive the rotating reciprocating motion of the rotating rod 100 of the brush head part, namely, the bristle reciprocating motion on the rotating rod 100 of the brush head part is driven. The brush head swing lever rotating shaft bearing 380 is sleeved on the brush head swing lever rotating shaft 370, so that the brush head swing lever rotating shaft bearing can be fixed in the assembly shell 310, and the waterproof leather sheath 390 is sleeved on the brush head swing lever rotating shaft 370 to prevent water from flowing into the electric toothbrush.

Further, the sensor 364 is mounted on the corresponding circuit board, and cooperates with the notch on the cam member 361 to control the bristles on the rotating rod 100 of the brush head portion to rub the teeth and the slits in a reciprocating manner when in use, and the bristles can return to the normal angle without being skewed after stopping;

the whole implementation process is as above, and the summary is simply: the regular rotary motion of the speed reducing motor 340 is converted into regular reciprocating swing of the rotary rod 100 at the brush head part through the combined action of the cam structure system 360 and the sliding rod 350, namely the reciprocating swing of the bristles on the rotary rod 100 at the brush head part; the sensor 364 controls the normal angle reset without deflection when the brush head rotary rod 100 stops swinging.

Example 2

In this embodiment, the cam member 361 and the inductor 364 in embodiment 1 are modified, but the rest of the solution is not changed, and the description is not needed.

In the embodiment, the cam member 361 is structurally modified, and the single sensor 364 is modified into the combined action of the magnet 365 and the hall sensor 366, so that the normal angle reset can be realized without deflection when the brush head part rotating rod 100 stops swinging. Two magnets 364 are placed in two cavities below cam member 361. For differences between the two schemes, please refer to fig. 4.

Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments described in the foregoing embodiments, or equivalents may be substituted for elements thereof.
