Field of the Invention The present invention relates to a toothbrush, and more particularly to a toothbrush of a type in which a handle portion for gripping the toothbrush is formed in a cylindrical shape as a whole, and a driving mechanism and other predetermined mechanisms are built therein. Regarding the handle structure.

持した際の違和感などにあった。2. Description of the Related Art Conventionally, for example, in an electric toothbrush,
The head portion on which the brush hairs are implanted is separable from the grip handle portion, and the handle portion is formed in a cylindrical shape as a whole, and at least the motor, the battery, and the rotational force of the motor are reciprocated at a constant rate. A power conversion mechanism for conversion is housed. Therefore, the handle tends to be large because of the built-in mechanism described above. Since the handle is a portion to be gripped by the user, there is a problem that operability is poor. In particular, the reason why electric toothbrushes have not been widely used in the past is not only high cost but also poor operability, that is, uncomfortable feeling when gripping the grip handle.

The same applies to toothbrushes and other types of toothbrushes having a built-in actuator.

ハウジングである把持用柄部の成型上の制限に由来する
ハウジング自体の大型化にある。The reason why the gripping handle is large, that is, the outer diameter is large, is not only due to the increase in the size of various built-in actuators, but also to the formation of the gripping handle which is the housing of those actuators. This is due to the increase in the size of the housing itself due to the above restrictions.

An object of the present invention is to provide a toothbrush handle structure that can prevent the handle itself from being enlarged.

In the toothbrush having a handle, the handle is divided into at least three parts in the longitudinal direction, and is formed by connecting at least three cylinders that are separately molded to each other.

8, a motor 22, a conversion mechanism 24 for converting the rotational power of the motor into a reciprocating rotational movement of the support shaft 20b, and a battery 50 as a power source are mainly incorporated. As is well known, the conversion mechanism 24 includes an intermediate gear 28 having an eccentric protrusion 32, a swing member 34 disposed so as to sandwich the eccentric protrusion 32 from both sides, and a swing member 34 fixed to the support shaft 20b. Since it is publicly known, detailed description is omitted. The support shaft 20b reciprocated by the conversion mechanism 24 protrudes from the outer cylinder 18 and extends into the receiving member 56. The receiving member 56 is reciprocally rotated by being fixed to the receiving member 56. The support shaft 20b comes into contact with the connection fitting 54 and terminates, and the base end of the other support shaft 20a contacts the connection fitting 54 via a spring 72. It is adapted to be inserted into the part 10. The support shaft 20a on the tip side is swingable via a pin 58, and a spring 7

It is formed as a housing for accommodating a built-in motor and the like by being connected to each other via the first and the third 73. The first outer cylinder 18b on the most distal side has a truncated cone shape with a small diameter on the distal side and expanding in the proximal direction, and the third outer cylinder 18c on the most proximal side has a frustoconical shape expanding in the distal direction. . The second outer cylinder 18a at the center is the switch knob 5
4 is provided on the outer wall of the second outer cylinder 18a, which is a portion which is most gripped by the user.

る。By dividing the outer cylinder 18 of the grip portion 12 into three parts in this way, the second outer cylinder 18a, which is the central part, is formed to have a smaller diameter than the other parts, so that the degree of freedom in molding can be improved. Has improved. That is, since the second outer cylinder 18a is a cylinder whose front and rear ends are open, it is possible to pull out the mold from both sides in the longitudinal direction during molding, and to form such a substantially wound-type cylinder. It became possible to do. This is not possible if the outer cylinder 18 is formed integrally or divided into two parts.

Since the outer cylinder 18 is divided into three parts, the second outer cylinder 18a, which is the part that the user grips most, can be formed with a minimum necessary diameter, thereby greatly improving the operability of the toothbrush. At the same time, it is possible to provide a grip portion 12 that is also clean in appearance. In the present invention, the grip handle portion is 3
It is not necessary to limit to division, and it goes without saying that division into four or more is possible. Also,
The present invention is not limited to an electric toothbrush, but can be applied to a toothbrush of a type in which another predetermined mechanism or actuator is housed in a grip handle.

Since the handle is divided at least into three in the longitudinal direction, the divided cylinder can be formed separately,
During molding, the degree of freedom in the direction in which the mold is removed is expanded, and this allows the shape of each cylindrical body to be determined more freely, thereby providing a handle portion with good operability and excellent appearance. There is an excellent effect that it can be done.
