Description

[Detailed description of the device]

The present invention relates to an electric toothbrush holder in which various commercially available hand toothbrushes are detachably attached and the toothbrush is continuously vibrated by rotation of an electric motor.

[0002]

[Prior Art]

 Conventionally, as an electric toothbrush, a motor is built in a cylindrical case, the rotation shaft of this motor is extended in the longitudinal direction of the case, a cam is attached to this rotation shaft, and a handle part provided with a brush at its tip is There is known a structure in which a side surface is in contact with the cam via a spring so as to be able to vibrate freely (Actual Kaihei No. 2-13421).

Further, there is known one in which the rotation of an electric motor is transmitted to a tooth brush holding housing by a pinion and a gear having an eccentric shaft (Japanese Patent Publication No. 42-27372).

[0004]

[Problems to be solved by the device]

 In each of the conventional electric toothbrushes described above, the rotation of the motor is changed into vertical movement by a cam or an eccentric shaft connected to the rotary shaft, and the toothbrush is vibrated by this.

However, such a mechanism that vibrates the toothbrush by changing the rotation of the motor into a vertical motion cannot continuously give a slight vibration to the toothbrush, and therefore the brushing effect of the gums etc. is sufficiently exerted. There are difficulties such as not being able to do so.

[0006]

[Means for Solving the Problems]

 In view of the above situation, this invention divides the inside of the cylindrical case with an intermediate plate, and fixes both ends of a convex leaf spring along the longitudinal direction on the upper surface of the intermediate plate to form a toothbrush holding chamber. On the lower surface of the intermediate plate, a motor holding chamber for fitting and fixing an electric motor and a battery accommodating chamber are provided inside, and an electric toothbrush holder with an eccentric weight on the rotary shaft of the electric motor is proposed. To do.

[0007]

[Action]

 The present invention has the above-described configuration, but the toothbrush has the handle portion sandwiched between the apex of the convex leaf spring and the spring provided on the upper wall of the cylindrical case, and at the same time, the electric motor is driven by the dry battery. When the rotation shaft of the motor rotates, the weight attached to it rotates eccentrically, and the motor vibrates slightly in resonance with the eccentric rotation of the weight.

The microvibration of the motor is transmitted to the convex leaf spring and continuously vibrates the toothbrush. Therefore, according to the present invention, the toothbrush can be continuously vibrated, and a good result can be obtained for brushing the gums.

[0009]

【Example】

 Hereinafter, the present invention will be described in detail with reference to the illustrated embodiments. Reference numeral 1 is an electric toothbrush holder according to the present invention, and 2 is a cylindrical case of the holder 1. The inside of the cylindrical case 2 is vertically divided by an intermediate plate 3 provided in the longitudinal direction.

Further, a hole 4 for inserting the handle B of the toothbrush A is provided in the upper part of the tip of the tubular case, and the tip and rear ends of the intermediate plate 3 are attached to the upper surface of the intermediate plate 3. A convex leaf spring 7 fixed to the upper surface of the case 2 is provided on the upper wall of the case 2 corresponding to the top of the convex leaf spring 7. The holding chamber 9 is formed.

On the other hand, on the lower surface of the intermediate plate 3, a storage chamber 11 for the dry battery 10 is provided at the rear part, and is partitioned by partition walls 12a and 12b at the intermediate part, and a motor holding unit for fitting and fixing an electric motor 13 therein. A holding chamber 14 is provided, and an accommodation chamber 16 for an eccentric weight 15 is provided at the tip portion.

The rotating shaft 17 of the electric motor 13 is projected into the housing chamber 16 through a hole 18 formed in the partition wall 12 a, and the tip of the rotating shaft 17 is supported by the eccentric bearing 15 a of the weight 15.

On the other hand, the tubular case 2 is provided with a cap 19 at its rear end, grips 20, ... On its lower surface, and a switch knob 21.

In the tooth dispersal A having the above structure, the handle B is inserted from the hole 4 into the holding chamber 9 of the toothbrush, and the handle B is placed between the top of the convex leaf spring 7 and the spring 8. It can be sandwiched between. Next, the switch knob 21 is turned on to bring the dry battery 10 into contact with the electric motor 13.

As a result, the rotary shaft 17 of the motor 13 rotates, the weight 15 provided at the tip of the rotary shaft 17 eccentrically rotates, and the eccentric rotation of the weight 15 causes the motor 13 to resonate and slightly vibrate. The slight vibration of the motor 13 is transmitted to the leaf spring 7, which causes the tooth dispersal A to continuously vibrate.

[0016]

[Effect of the device]

 In short, according to this invention, the leaf spring 7 is continuously vibrated by the eccentric rotation of the weight 15, and this is transmitted to the toothbrush A. In this way, the toothbrush A is continuously vibrated slightly. As a result, it is possible to perform extremely good brushing of gums.
