BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electric toothbrush set in which an electric toothbrush main body is placed on a set stand of a charger, and the electric toothbrush main body is held and charged by the charger.

[0002]

2. Description of the Related Art Conventionally, in this type of electric toothbrush set, for example, as shown in FIG. 10, a charger 1 is provided on one side with a convex receiving portion 3 for holding the electric toothbrush 2. The receiving part 3 has a recess 3a formed on the upper side thereof, and a cylindrical set table 4 is provided substantially at the center thereof. The set base 4 has plus and minus terminal holes 4 on its top surface.
a and 4b are provided, and a convex portion 4c is provided in the height direction of the peripheral surface.

On the other hand, the electric toothbrush 2 has a toothbrush 6 attached to the upper end of the electric toothbrush main body 5 and, as shown in FIG.
・ Set 8 downward. A cylindrical projection 5a is provided downward on the outer periphery of the lower end, and a recess 5b is formed on the inner periphery of the projection 5a.

When the electric toothbrush 2 is not used,
The convex portion 4c of the set table 4 is replaced with the concave portion 5b of the electric toothbrush main body 5.
And positive and negative terminals 7.8 are inserted into the positive and negative terminal holes 4a and 4b of the set base 4, respectively. The plus and minus terminals (not shown) in the terminal holes 4a and 4b respectively contact and electrically connect. Then, the electric toothbrush 2 is placed on the set stand 4 and held, and the charger 1 charges the electric toothbrush.

[0005]

However, in the above-mentioned conventional electric toothbrush set, when the electric toothbrush 2 is not used, the fitting of the convex portion 4c and the concave portion 5b is not easy,
Therefore, it is troublesome to mount and hold the electric toothbrush 2 on the set table 4.

Therefore, an object of the present invention is to easily put the electric toothbrush on a set stand of a charger and hold it when the electric toothbrush is not used.

To hold the electric toothbrush body 12 and charge the same.

[0009]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 7 shows an electric toothbrush set according to an embodiment of the present invention. Reference numeral 10 in the drawing indicates an electric toothbrush. The electric toothbrush 10 stands up and is held by the charger 11.

The electric toothbrush 10 includes an electric toothbrush main body 1.
2, a toothbrush 13 is detachably attached. The electric toothbrush body 12 has a cylindrical shape that can be gripped with one hand, and as shown in FIG. 1, a cylindrical protrusion 14 a is formed downward at the lower end of the outer case 14, and is formed on the inner periphery of the protrusion 14 a. An arc-shaped concave portion 14b is provided. Further, the bottom plate portion 14c of the outer case 14 is provided with bar-shaped plus and minus terminals 15 and 16 projecting downward.

On the other hand, the charger 11 is provided with a mounting recess 20 on one side of the support base 19 and a receiving base 21 on the other side. The receiving part 21 has a concave portion 21a formed on the upper side thereof, and a cylindrical set base 23 projecting upward at substantially the center in the concave portion 21a. The set table 23 has arc-shaped plus and minus terminal holes 23a and 23a on its top surface.
b is provided on the same circle a. 2 and 3 is provided on the outer surface of the peripheral wall 23c of the set stand 23 in the height direction.
As shown in FIG. 7, holes 23e are provided to face each other.

As shown in FIG. 2, a pair of stoppers 25, opposed to each other, are formed on the bottom wall 23f of the set table 23 in a radial direction perpendicular to the radial direction between the holes 23e. 25 are provided. The stoppers 25 are formed in a plane T shape by a partition plate portion 25a extending in the radial direction and a receiving plate portion 25b perpendicular to the partition plate portion 25a, and the entire top surface side is rounded as shown in FIG. And formed.
The receiving plate 25b may be formed in a triangular shape.
As shown in (1), it may be formed in a slightly elongated shape. Then, as shown in FIG. 2, the plus terminal plate 30 is arranged on the left side of the stoppers 25 in the figure, and the minus terminal plates 30 and 31 are arranged on the right side.

Plus and minus terminal plates 30 and 31
As shown in FIG. 5 (a minus terminal plate is not shown),
It has a semi-cylindrical shape as a whole, and has connection pieces 30b and 31b that are bent outward at lower end edges of the main body plate portions 30a and 31a. The main body plate portions 30a and 31a each have an open shape with the upper ends thereof warped outward. Further, a part of both ends of the main body plate portions 30a and 31a is cut and raised in a rectangular shape, and is bent outward to form spring portions (biasing members) 30c and 31c.
Is formed. Then, the positive and negative terminal plates 30 and 31 are respectively connected to the arc-shaped terminal holes 23a.
Arranged along 23b. Thus, as shown in FIGS. 2 and 3, the connection pieces 30b and 31b are protruded from the holes 23e and 23e of the peripheral wall portion 23c and are arranged, and the spring portions 30c and 31c are pressed against the peripheral wall portion 23c. The positive and negative terminal plates 30 and 31 are urged inward by the repulsive force and pressed against the receiving portions 25b of the stoppers 25 and 25. Then, these plus and minus terminal plates 3
Each of the connection pieces 30b and 31b of the
4.35 are connected.

When the above-described electric toothbrush 10 is not used, the set base 23 is inserted into the arc-shaped concave portion 14b shown in FIG.
Of the electric toothbrush main body 12 is regulated by fitting the convex portions 23d of the electric toothbrush main body 12 so that the electric connection between the electric toothbrush main bodies 12 is not reversed. The minus terminals 15 and 16 are fitted into the plus and minus terminal holes 23a and 23b of the set base 23, respectively, and inserted as shown in FIG.
31 and is electrically connected. Then, as shown in FIG. 7, the electric toothbrush main body 12 is placed on the set base 23, and the electric toothbrush 10 is held by the charger 11.

In the illustrated embodiment described above, the projection 14a is formed at the lower end of the outer case 14 of the electric toothbrush body 12.
However, for example, as shown in FIG.
It is desirable that the depth D of a is larger than the length L of the plus and minus terminals 15 and 16. However, in this case, when fitting the plus and minus terminals 15 and 16 into the arc-shaped terminal holes 23a and 23b, respectively, the projection 14a is first put on the outer periphery of the set base 23 so as to cover both terminals 15 and 16. Regulate the radial movement of Then, the terminals 15 and 16 can be rotated in the horizontal direction and guided to the corresponding terminal holes 23a and 23b for smooth insertion.

Further, in the illustrated embodiment described above, the urging members for resiliently pressing the plus and minus terminal plates 30 and 31 to the plus and minus terminals 15 and 16 are provided on the respective terminal plates 30 and 31.
Although the spring 31 has the spring portions 30c and 31c, an independent member may be used as the biasing member.

[0017]

Therefore, according to the present invention, the concave portion is made to have a large arc shape with respect to the convex portion for positioning the electric toothbrush and the charger, and each terminal hole into which the plus and minus terminals are fitted is circular. Since the arc and the plus and minus terminal plates in the terminal holes are formed in a semi-cylindrical shape, when the electric toothbrush is not used, the electric toothbrush can be easily put on the set stand of the charger without any trouble and held. Can be.
