Definitions
- the present invention relates to an electric toothbrush, and more particularly to a mechanism for reciprocating a disk-shaped brush body about an axis that intersects at an arbitrary angle including a right angle with respect to a longitudinal direction of a grip portion of the electric toothbrush.
- the rotating motion of the motor and the drive shaft of the motor is reciprocated by the grip portion of the electric toothbrush.
- a drive mechanism for converting into motion is provided.
- a connection shaft is connected to the output shaft of the drive mechanism via an angle-enhancing mechanism for expanding the rotation angle of the reciprocating rotation of the output shaft, and furthermore, a miter is provided between the tip of the connection shaft and the disk-shaped brush body.
- a miter gear structure is provided.
- the brush body is reciprocated about an axis perpendicular to the connection axis.
- the miter gear structure is provided at the tip of the electric toothbrush, and the angle increasing mechanism is provided between the output shaft and the connection shaft of the drive mechanism.
- the angle increasing mechanism is provided between the output shaft and the connection shaft of the drive mechanism.
- the groove of the cylindrical brush body must be at least longer than the turning diameter of the crank-shaped portion at the tip of the connecting shaft, so that the brush body is inevitably large. I can't get it. Therefore, as in the case of the first conventional example, there is a certain limit in reducing the size or thickness of the head portion that can be put in the mouth of the user. Further, since the connecting shaft is directly connected to the drive shaft of the motor, it is practically impossible to tilt the head portion at an arbitrary angle with respect to the grip portion, and the operability during brushing is somewhat inferior. Furthermore, the connecting shaft and its bearing portion must be machined with high accuracy. If the accuracy is poor, the driving force transmission efficiency is reduced and noise is generated.
- the rotational movement of the motor and the drive shaft of the motor is changed into a reciprocating linear movement at the grip portion of the electric toothbrush.
- a drive mechanism for converting is provided.
- the output shaft of the drive mechanism is connected to a connection shaft having a rack formed at the tip.
- the brush body is reciprocally rotated about a direction perpendicular to the connection axis by screwing a rack at the end of the connection axis that reciprocates linearly with a pinion provided on the rotation axis of the brush body.
- the user is compared with the first or second conventional example. It is possible to make the head part that can be put in the mouth of the car smaller or thinner.
- the connecting shaft is directly connected to the output shaft of the drive mechanism, it is virtually impossible to incline the head part to an arbitrary angle with respect to the grip part. Somewhat inferior.
- the rotation of the motor is controlled by the drive mechanism. After the conversion to the reciprocating motion of the output shaft, it is converted to the reciprocating rotary motion of the brush again, so the driving force transmission efficiency is somewhat low. Disclosure of the invention
- the present invention has been made to solve the above-described problems of the conventional example.
- the rotating shaft and the head of the brush body are optional with respect to the grip. It is possible to provide an electric toothbrush that can be tilted at an angle of 1 mm and that can reduce or reduce the thickness of a head portion that can be inserted into a user's mouth, and that has high driving force transmission efficiency.

- a second motion converting mechanism provided between the two end portions, and configured to convert a rotational motion of the lever member into a reciprocating rotational motion of the brush body.
- the rotational motion of the drive shaft of the motor is once converted into the oscillating motion of the lever member, and the oscillating motion of the lever member is converted into the reciprocating rotational motion of the brush body.
- the brush body can be made thinner than the first and second conventional examples using a mechanism or a crank mechanism.
- a lever member that swings around a predetermined swing axis is used as a connecting member for transmitting the driving force of the motor to the plush body, dimensions inside the head part (height of the internal space) Can be reduced to a height obtained by adding a predetermined clearance to the thickness of the lever member. As a result, it is possible to make the head portion that can be put in the user's mouth smaller or thinner.
- the swinging lever member is connected to the drive shaft of the motor via the first movement conversion mechanism, the drive shaft of the motor is not necessarily different from the conventional connection shaft which rotates, reciprocates linearly, or reciprocates. Provided in the same direction as the shaft or the output shaft of the drive mechanism Need not be.
- the lever member is connected to the brush body via the second motion conversion mechanism, it is not always necessary to make the rotation axis of the brush body orthogonal to the rotation surface of the lever member. As a result, the rotating shaft and the head of the brush body can be inclined at an arbitrary angle with respect to the grip, and the operability during brushing can be improved.
