Abstract
The utility model relates to a toothbrush with a rectangular intersecting surface brush bristles, which can improve the tooth brushing effect. People widely adopts a tooth brushing action of dragging the toothbrush right and left, because the direction of the motion of the brush bristles is vertical to tooth space, the toothbrush is difficult to reach the bottom of the tooth space, and then the tooth space can not be cleaned. The rectangular intersecting surface brush bristles 1 is adopted by the utility model, the separation angle of a main centroid inertial shaft of the minimum intersecting surface of the brush bristles and the axial line of a brush rod is an acute angle. When the teeth is brushed by dragging the toothbrush right and left, the brush bristles do swinging movement along the tooth space, so the tooth space can be effectively cleaned. The utility model can be suitable for various tooth brushing actions, even if the tooth brushing action of dragging right and left is adopted with the toothbrush, the satisfactory tooth brushing effect can be achieved.
Description
The utility model is a kind of toothbrush with rectangular cross section bristle that can improve toothbrushing effect.
The correct action of brushing teeth should make bristle along the backlash direction friction flank of tooth that moves, so that remove remaining foreign material in the backlash.
Because tooth is long and narrow arrangement, the action of implementing correctly to brush teeth needs skill and patience, and misoperation can be damaged gum, therefore, about drag toothbrush the action of brushing teeth be widely adopted.Because the bristle motion direction is vertical with backlash, make bristle touch the backlash bottom, toothbrushing person must apply bigger pressure to the flank of tooth, its the possibility of result causes damage gum, the wearing and tearing of acceleration flank of tooth method Lang matter, brush holder to fracture, and therefore, has the bristle of some toothbrushes to be wavy arrangement, so that the top bristle can more easily touch the backlash bottom, but because bristle also is to move back and forth about vertical backlash, bristle contacted with the moment of backlash, did not reach above-mentioned usefulness and correctly brushed teeth and move the effect of brushing teeth.
The purpose of this utility model is a kind of toothbrush that can adapt to the various actions of brushing teeth of design, uses this toothbrush, even drag the action of brushing teeth of toothbrush about adopting, also can obtain the toothbrushing effect that obtains with the action of correctly brushing teeth.
The purpose of this utility model is by selecting suitable bristles shape of cross section and arrangement mode to realize, its operation principle is seen Fig. 1, it among the figure bristles of a rectangular cross section, x0, y0 are the bristle cross section dominant shape heart axes of inertia, and bristle cross section dominant shape heart the moment of inertia Jx0 is a minimum of a value, Jy0 is a maximum, axle x0 and brush rod axis angle α are acute angle, when bristle with brush holder support together when direction A moves back and forth, bristle is subjected to the frictional resistance effect generation flexural deformation between its top and tooth; Around axes of inertia x0 axle swing with least moment of inertia Jx0, bristle tips produces the slip of the direction of vertical x0 axle on the flank of tooth, because glide direction and backlash is acute angle and bristle has compliance, under the guiding of backlash, bristle tips can be slided along backlash, foreign material in the scraping backlash reach the purpose that cleans the teeth.
Embodiment of the present utility model sees Fig. 2, bristle 1 is a rectangular cross section, and bristle also can adopt non-circular, non-regular polygon, has a pair of unequal cross section dominant shape heart the moment of inertia, wherein Jy0 is that maximum, Jx0 are for minimum cross section, as ellipse, round rectangle etc.The bristle cross section dominant shape heart axes of inertia x0 (see figure 1) and the brush holder support axis angle of brushing cluster are an acute angle, because the guiding and the action inaccuracy of brushing teeth of backlash, bristle cross section dominant shape heart axes of inertia x0 and brush holder support axis angle also can be zero degree.Two row brush tufts are the axial symmetry setting with the brush rod axis, and the power that bristle tips is born when backlash slides offsets, and make toothbrushing person gripping brush holder laborsaving, stable operation.
Claims (3)
1, a kind of toothbrush with rectangular cross section bristle that can improve toothbrushing effect, this toothbrush has bristle 1, it is characterized in that bristle 1 has non-circular, non-regular polygon cross section, bristle 1 cross section dominant shape heart the moment of inertia Jx0, the unequal Jx0 minimum of Jy0, Jy0 maximum.
2, claims 1 described toothbrush with rectangular cross section bristle in base area is characterized in that bristle 1 cross section dominant shape heart axes of inertia x0 and brush holder axis angle α are an acute angle.
