Description

[Detailed description of the invention] (a) Industrial application field The present invention relates to an electric toothbrush having a brush part that is rotated by a motor that is powered by a battery. This relates to a storage box that is divided into two parts for storage.

(b) Conventional technology A conventional storage box for electric toothbrushes is, for example,
- As disclosed in Publication No. 9262, a drive unit housing part houses a drive unit of an electric toothbrush on one side and is equipped with a charging mechanism for charging a rechargeable battery built into the drive unit inside, and the other side A brush part accommodating part is integrally molded in which the brush part, which is removably fitted to the drive shaft of the motor which is protruded from the upper part of the drive part, is housed upright.

By the way, when you brush your teeth, you usually brush your teeth while facing the mirror in the washstand, but the area for placing items in the washstand has only a limited area, and the integrated molded storage box shown above cannot be used when installed in its optimal condition. It may extend into the sink area and become unstable.
Furthermore, when cleaning the brush part housing part, it is inconvenient if the brush part housing part is integrally molded, since it is necessary to wash the brush part housing part while paying attention to the power cord of the drive part housing part which has a charging function.

(c) Purpose of the invention The present invention was devised in view of the above points, and the brush part storage part and the drive part storage part are separated,
To provide a storage box for an electric toothbrush that improves usability by making both storage parts separable, has good assemblability, and has a small number of parts.

(d) Structure of the invention The invention consists of a box A that houses the drive part of an electric toothbrush and has an engaging protrusion on its side, and a box that houses the brush part and has an engaging groove that engages with the engaging protrusion. This storage box for an electric toothbrush consists of a body B, and both box bodies A and B are removable, wherein the box body A consists of two upper and lower members, one of which has a fitting claw. The other is a storage box for an electric toothbrush, which has a through hole on the inside of the engaging protrusion that fits with the fitting claw.

(E) Embodiment An embodiment of the present invention will be explained using the drawings. FIGS. 1 and 2 are perspective views of a storage box A for a drive part and a storage box B for a brush part of an electric toothbrush storage box according to an embodiment of the present invention when separated and when they are combined. . In FIG. 1, reference numerals 2 and 1 are the lower member of the storage box A and the upper member having a recess 3 for storing the drive unit, and a small protrusion 4 integrally formed on the lower member 2,
4 and a protruding piece 5 integrally formed on the upper member 1, an engaging protrusion 6 is formed on the side surface of the storage box A. Reference numerals 7, 7, . . . are protruding arms integrally molded on the storage box B, and between the protruding arms, there is a brush portion (not shown) that is removably fitted to the drive shaft of the motor of the drive unit (not shown). (not shown) can be stored upright. Furthermore, an engagement groove 8 that engages with the engagement protrusion 6 is provided on the side surface of the storage box B, and by sliding the storage box A horizontally relative to the storage box B, as shown in FIG. Storage boxes A and B can be combined. Therefore, even in places with a limited area, such as the product storage area of a washstand, by separating the storage boxes and placing them separately, it is possible to prevent the storage boxes from overhanging the washbasin area. Since the brush part storage box can be removed from the drive part storage box without becoming unstable, the brush part storage part can be easily cleaned.

FIG. 3 is an exploded perspective view of the components of the drive unit storage box A of the present invention, FIG. 4 is a partial perspective view of the arrowed part in FIG. 3, and FIGS.
They are a sectional view and a - sectional view. Upper and lower 2 members 1,
The drive section storage box A consists of two parts, in which a fitting claw 9 formed on the lower member 2 is fitted into an inner through hole 10 of a protruding piece 5 formed on the upper member 1, and a boss on the lower member 2 is fitted. A screw 13 is inserted from below the portion 11 and is screwed onto the boss portion 12 of the upper member 1 to be coupled. When the two upper and lower members 1 and 2 are connected, instead of screwing with the screw 13, a locking claw and an engaging protrusion are provided on the inner surface of the upper and lower members 1 and 2 opposite to the side surface where the fitting is performed using the fitting claw. The pieces may be provided and combined. Further, due to this connection, the charging coil 14 is sandwiched between the bottom surface of the drive unit storage recess 3 of the upper member 1 and the annular rib 15 disposed on the inner bottom surface of the lower member 2. Note that the small protrusions 4, 4 provided on the lower member 2, which form part of the engagement protrusion 6, are provided apart from each other in order to form the fitting claws 9 (due to the need for die cutting). The small projecting pieces 4, 4 prevent the upper and lower members 1, 2 from shifting from each other in the front-rear direction. Furthermore, the fitting claw 9
Since it is hidden behind the engaging protrusion 6, the aesthetic appearance is not spoiled. In addition, 16 in the figure is a code holder, which includes a date plate 17 glued to the front surface of the lower member 2, a day change bar 18 held between the upper and lower members 1 and 2, and a transparent plate 19 located in front of the day change bar. A calendar is constructed.

(f) Effects of the invention The present invention provides an engaging protrusion and an engaging groove that engages with the engaging protrusion in the box body A that houses the drive part and the box body B that houses the brush part, respectively. Since the boxes A and B are made separable, usability is improved as described above, and the box A is divided into two upper and lower members, and a fitting portion of the upper and lower two members is provided at the engagement protrusion. The electric toothbrush is easy to assemble and has a reduced number of parts because the engaging protrusion is used for the fitting of the upper and lower two members and the engagement of the box body AB, and the fitting part has a locking structure. This has the effect of providing a storage box for use.
