The specific embodiment

Below in conjunction with accompanying drawing four kinds of adjustable toothbrushes are elaborated.

Fig. 1 can regulate the overall structure schematic diagram of toothbrush for folding control formula.

Folding control formula adjustable toothbrush is by movable brush 1, fixedly brush 2, axle 3, axle 4, brush holder 5 and folding move control head 6 and constitute.The first half of described fixedly brush 2 (including the part of bristle and the first half of its handle) has through hole (7.Perpendicular to the brush holder direction, with bristle in the same way), as Fig. 1-2.Fixedly the rear portion of the handle of brush 2 also be through hole (with brush holder in the same way), and in order to create bigger activity space, place's size is little in the middle of in the hole, outer size is big, as the hourglass shape, folding moves control head 6 just therein, and combines by axle 4 with the hole wall of both sides at the minimum place of intermediate sizes, like this, control head 6 just can be free up and down in certain angle; The axis hole 9 that axle 3 passes on the handle of fixedly brush in axis hole 8 on the handle of movable brush 1 and its outside connects them.The end of movable brush 1 combines with the top of above-mentioned control head 6, and its combination is various, and what adopt among the figure is concavo-convex phase button, also can be post hole built-in type etc.So when upwards folding moves brush holder 5, because the effect of axle 4, the front portion of the control head 6 that is connected as a single entity with it will descend, promptly and movable brush 2 under the double action of axle 3 and control head 6, its front end has the part of bristle that to a certain degree rising will be arranged, promptly exceed with respect to not moving on every side fixedly brush 2, thereby bristle part seems to resemble " protruding " the Chinese character from the right and left, the characteristics of this shape are that it is equivalent to the little brush of a part, so just can overcome because the shortcoming that can not contact fully that the large tracts of land brush causes, thereby clean the rough disagreement masticatory surface of molar very effectively, otherwise roll over brush holder 5 downwards, by

axle

3,4 and the effect of the moving control head 6 of folding, movable brush 1 relative fixed brush 2 is low, has promptly formed " protruding " shape, the bristle that this moment, both sides exceeded can effectively be avoided stopping of tooth corner angle, as the arm of same elongation, the inboard of tooth and root and gum contact position are carried out effective cleaning, promptly reach its intended purposes.Can also can reach its intended purposes equally for movable brush 1 and control head 6 and brush holder 5 omit axle 3 simultaneously for one in addition.In order to make control that feel more be arranged and to be easier to keep stable, can make the tongue and groove that cooperatively interacts at the inwall in moving control 6 of folding and the hole that is in contact with it, be their the contact the surface as two facing to washing board, handle like this that control is more had after dynamics and the adjusting is not yielding, in addition also can be by position to (concavo-convex) groove, the size and the selection of quantity just can make the user know the degree of movable brush lifting by feel, and all very stable after the adjustment at every turn.

Preventing that function that toothpaste drops is achieved in that before brushing teeth and adjustable toothbrush be adjusted to " recessed " shape described in " summary of the invention " in addition, toothpaste is clamp-oned in the groove of brush centre, brush just can be opened Tooth paste brush for moving several times and avoid bulk toothpaste to drop gently.Below herewith several, will no longer illustrate.

Below the three kinds of brushhead portions that can regulate toothbrush can regulate the consistent of toothbrush with this kind, so no longer carefully state, only introduce their control section in detail.

Take out the adjustable toothbrush of control formula, its first half and a kind of identical (whole brushhead portion in the middle of be last lower through-hole) noted earlier are by movable brush 11, fixedly brush 12, spools 13, brush holder 14 and twitch control head 10 constitute.The end of the handle of described movable brush 11 approaches and engraves the through hole 15 shown in Fig. 2-1, and this through hole can be beaded, flat etc.Pass the fixedly hole at brush 12 rear portions with brush holder 14 for the twitch control head 10 of one.Control head 10 is shown in Fig. 2-2, the end is thin and little excrescence 16 arranged, after the toothbrush assembling finishes, it just is enclosed within the described through hole 15 in front, because the through hole 15 relative control head directions of motion tilt, simultaneously since the control head 10 at excrescence 16 places only with horizontal movement, so when outwards taking out brush holder 14, excrescence 16 just slides in through hole 15, correspondingly the handle of the movable brush of co-located just has rising to a certain degree, promptly and brushhead portion descend to form " recessed " shape, then become " protruding ", promptly reached purpose otherwise inwardly push away.In order to make user's feel good, and can make each step control more stable, the surface treatment of control head and the through hole that is in contact with it can be become the tongue and groove described in the folding control formula, also can take the inconsistent method of internal diameter segmentation (situation of essence) for vertical tongue and groove is elongated.
