Description

  For portable toothbrushes that have an external appearance formed of a cylindrical outer case and cap, the length of the brush part that pulls out the brush part to a predetermined position when using it, and stores it short after use. The present invention relates to a mechanism of a brush replaceable non-disposable portable toothbrush having an adjustment function.

  As shown in FIGS. 10 and 11, the conventional method for adapting the length of the portable toothbrush according to the situation at the time of use and after use (at the time of storage) is as follows. ) There are three types of removable type. (A) The folding type has a brush portion shaft end 9 hinged to one end of a grip portion 10 having a U-shaped or U-shaped cross section, and the grip portion is rotated while rotating the brush portion 8 about the rotation shaft. A method that fits the situation at the time of use and after use (at the time of storage) with a method of fitting into and out of 10. (B) The insertion / removal type is performed by inserting / removing the brush portion shaft end 14 or the brushed head portion 13 into the opening 12 of the gripping portion 11, so that it can be used and used (stored). Corresponding method. (C) The detachable separation type is an idea of dividing a general toothbrush (not shown) in which the brush part and the grip part are integrated into a brush part 15 and a grip part 16 into two parts. The joint part of the divided brush part 15 and the grip part 16 is provided with a detachable fitting mechanism such as convex and concave, and a detachable mechanism such as a screw, so that the appearance as a portable toothbrush is arranged. is there.

  In the conventional methods (A), (B), and (C) in which the shape of the portable toothbrush is adapted to the situation at the time of use and after use (at the time of storage), the replacement time of the brush part is the life of the product ( At the time of disposal). Also, when a member other than the brush portion is damaged, the point in time is the life of the product (during disposal).

  The present invention divides the components of the portable toothbrush into the functional members of the toothbrush body 7 shown in FIG. 4 and the exterior members of the exterior case 4 and cap 5 shown in FIG. Provide a function to adjust the length of the brush part 1 according to the situation after storage (when stored), and if the member needs to be replaced due to wear or damage, the member can be replaced easily and is disposable. Create a portable toothbrush mechanism that can be used for a long time. Incidentally, the exterior member serves to protect and store the functional member.

  Hereinafter, the present invention will be described using reference numerals in the accompanying drawings. The present invention relates to a brush part head 1a having a hair transplanted, a brush part 1 having a brush part shaft end 1b having a retaining protrusion 1c, and the brush part 1 A functional member of a toothbrush body 7 (FIG. 4) constituted by a gripping member 2 (FIG. 3) composed of a gripping member 2 and a gripping member 3, and an exterior member for housing the toothbrush body 7 as the functional member The shape of the gripping body 6 composed of the gripping member 2 and the gripping member 3, which is composed of the outer case 4 and the cap 5 (FIG. 5) of the toothbrush body 7 and sandwiching the replaceable brush part 1, is And designed in accordance with the shape of the cap 5.

  The effects of the present invention are as follows. (1) Consumable brush by designing the functional member of the brush part 1 and the gripping body 6 (FIG. 3) and the exterior member of the outer case 4 and cap 5 (FIG. 5). The part 1 can be easily replaced, and (2) the exterior member does not need to be periodically replaced like the brush part 1 and can be used for a long time. Further, even at the time of final disposal, it can be easily separated without using a tool, and (3) separation and disposal of each constituent member is facilitated.

  In the embodiment shown in FIG. 1, the basic shapes of the gripping member 2 and the gripping member 3 that sandwich the brush portion 1 are symmetrical, and a tool is used for coupling and separation of the gripping member 2 and the gripping member 3. It is the structure which can pinch the brush part 1 easily.

  The mechanism in which the brush unit 1 slides while being held between the gripping member 2 and the gripping member 3 is configured such that the gripping member 2 and the groove 3a provided inside the gripping member 3 are symmetrically provided in the gripping member 2a and the groove 3a. The brush portion 1 held between the gripping member 2 and the gripping member 3 slides, and the brush portion 1 is pulled out to a predetermined position set in advance during use, and is shortened and stored after use. FIG. 7 is a storage state diagram of the brush unit 1.

  As shown in FIG. 8, the mechanism that the brush unit 1 fixes at a predetermined position that is set in advance is used to prevent the brush unit 1 from being pulled out by pulling the brush unit 1 out of the gripping body 6. The protrusion 1c moves and fits into the groove 2a provided symmetrically inside the gripping member 2 and the gripping member 3, the recess 2b provided around the middle of the groove 3a, and the recess 3b so that the brush portion 1 is in a predetermined position. Secure with. Further, as shown in FIG. 9, the brush portion 1 is fixed in the state of being accommodated in the gripping body 6 so that the groove 2a, the recess 3c provided at the end of the groove 3a, and the brush portion shaft end 1b are fixed. The retaining protrusion 1c is fitted and fixed.

Replacement of the brush unit 1 is performed according to the following procedure (FIG. 1).
(1) The outer case 4 and the cap 5 are removed. (2) The gripping body 6 of the toothbrush main body 7 is separated into the gripping member 2 and the gripping member 3, and the gripping member 2, the groove 2 a provided in the gripping member 3, and the brush part 1 sandwiched between the grooves 3 a are replaced with new ones. Exchange. (3) A new brush portion 1 is sandwiched between the groove 2 a of the gripping member 2 and the groove 3 a of the gripping member 3 to constitute the toothbrush body 7. (4) After mounting the exterior case 4 on the opposite side of the brush portion 1 to the toothbrush body 7, the cap 5 is mounted on the brush portion 1 side to complete the replacement of the brush portion 1. (5) The procedure for cleaning and draining the gripping body 6 and the subsequent assembly are also performed in the same procedure as the replacement of the brush unit 1.

  It is a block diagram of each member of this invention.   It is a perspective view of the brush part 1 of this invention.   It is an assembly state figure of the holding body 6 which combined the holding member 2 and the holding member 3 of this invention.   It is an assembly state figure of the toothbrush main body 7 which clamped the brush part 1 with the holding member 2 and the holding member 3 of this invention.   It is a perspective view of exterior case 4 and cap 5 which are exterior members of the present invention.   It is a sliding state figure of the brush part 1 of this invention.   It is the accommodation state figure of the toothbrush main body 7 of this invention.   It is the center vertical side view which looked at (a) holding part 2 side and (b) holding part 3 side at the time of use of the present invention.   It is the center vertical side view which looked at (a) holding part 2 side and (b) holding part 3 side after use (at the time of storage) of the present invention.   It is a use state figure of the conventional (I) folding type (B) insertion / removal type (C) attachment / detachment separation type portable toothbrush.   It is explanatory drawing which showed the accommodation state of the conventional (b) folding type (b) insertion / removal type (c) attachment / detachment separation type portable toothbrush.
