CONSTITUTION:The toothbrush consists of a housing 1 which contains a toothbrush driving mechanism, a housing 2 which contains a battery power source, and a toothbrush body 3 connected to a driving shaft 10 protruded from one end face of the housing so as to be freely attachable and detachable, and both the housings l, 2 are connected so as to be freely bendable and turnable by fitting a bearing part 11 provided on the lower end edge of the housing 1 into a shaft part 21 protruded from both side faces of the upper end edge of the housing 2. Also, on the joint surfaces opposed to each other at the time when both the housings 1, 2 are bent and folded, containing recessed parts 12, 22 for containing the toothbrush body 3, a switch 13, and a recessed part 23 into which a projecting part of the switch 13 is fitted are formed.

Description

[Detailed description of the invention] [Industrial application field]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electric tooth brush, and more particularly to a portable electric tooth brush.

[Conventional technology]

Conventional electric toothbrushers have a power source and a toothbrush drive mechanism built into an elongated cylindrical housing, and a toothbrush body is detachably attached to the toothbrush drive mechanism. .

[Invention or problem to be solved]

Therefore, if you carry it with you for travel, etc., you have to put it in a separate case, otherwise dust will stick to the toothbrush body, and
It has become bulky. The present invention has been made in view of these points, and its purpose is to provide an electric tooth brush that is compact and hygienically portable.

[Means to solve the problem]

Therefore, the present invention includes a first housing that includes a tooth brushing drive mi, a second housing that includes a power supply unit,
It consists of a tooth hanging body that is detachably connected to the tooth hanging drive mechanism, and the first housing and the second housing are connected so as to be bendable and rotatable, and when both housings are bent, It is characterized in that a tooth holder housing part is provided on the joint surface of the tooth holder. 1 Effect] According to the present invention, by folding both house sinks, it is possible to make a compact toothbrush 1~, and the tooth brush body can be stored between both house sinks. ``Embodiment'' The present invention will be described in detail below based on the illustrated embodiment. A drive shaft protruding from one end surface] is detachably connected to a tooth hanging shaft 3, and both housing sinks 1
, 2 are 1., 2 of the house sink 2 as shown in FIG. A bearing part 1 provided at the lower end edge of the housing sink 1 is fitted into a shaft part 21 protruding from both side surfaces of the end edge, so that the housing sink 1 is connected so as to be bendable and rotatable. When both the housing sinks 1 and 2 are bent and folded, the joint surfaces facing each other have four storage parts 12 and 22 for storing the toothbrush rest 3, a switch 13, and a switch 1.
A fourth part 23 into which the protruding part 3 fits is formed,
Also, both housing sinks 12 are set in a straight line, and the housing 1
Terminals 1, 4, and 24 are respectively disposed on opposing surfaces that face each other when the saw hook 15 protruding from the housing sink 2 is engaged with the engagement recess 25 of the housing sink 2 by the force of the spring 18. There is. As shown in FIG. It is energized by. Therefore, in this electric tooth brushing, as shown in FIG. Then, the tooth hanging body 3 is removed from the drive shaft 10, the hook 15 is removed from the housing 2, and both are folded, and at this time, the tooth hanging body 3 is removed from the housing 2, and the tooth hanging body 3 is removed from the housing 2. By storing the body 3, as shown in Figs. 6 and 7, it is possible to avoid dust and dirt during the tooth brushing period 3 and to make it in a state of dust and dirt. Also, at this time, the switch 13 is hidden, so there is no chance of accidentally turning on the power. Furthermore, even when the toothbrushing body 3 is stored, the handle of the toothbrushing body 3 is closed. The reason why the portion of the drive shaft 10 protrudes outside is to protect the drive shaft 10 that is protruding from the housing 10. As shown in FIGS. 8 and 9, the drive shaft 10 is attached to the base 1
Even if the drive shaft 10 is divided into Oa and the shaft 101) connected to it by shaft]-0c, and the drive shaft 10 can also be folded, it is possible to prevent a load from being applied to the drive shaft]0 when carrying it. can. As shown in Figures 10 to 12, the length of the house sink 2 is made slightly longer than the house sink 1, a slidable cover 4 is provided at the bottom of the house sink 2, and both house sinks 1 and 2 are folded. At this time, the cover 4 may be slid toward one end surface of the housing sink 1 to cover the drive shaft 10 with the cover 4. In the figure, 18 is a slide 1 to 1 of the cover 4 which is also attached to the housing 1 side.In this case, both housings 1 and 2 may be opened inadvertently when the cover 4 is not folded. As shown in Fig. 1-3, the cover 4 is rotatably connected to the lower end of the housing 2 by a shaft 28, and the cover 4 can be rotated with the housing 2 folded. For example, the cover 4 may cover the drive shaft 10. In the figure, 41 and 4
2 is a hook for fixing the cover 4.

【Effect of the invention】

As described above, the present invention can be made compact by folding both housings, and at this time, the tooth hanging can be stored between the two housings. It can prevent dust from getting on the body, and it can be carried in a compact and hygienic condition without the need for a separate case or the like.
