Description

Toothbrush

The utility model relates to the utensil that the cleaning between cog is used, and outstanding tool is the improvement to a kind of toothbrush.

As everyone knows, brushing teeth is a kind of means that keep oral hygiene, certainly toothbrush is the thing of the indispensability of brushing teeth, the structure of present normally used toothbrush is made up of head toothbrushes and toothbrush handles, head toothbrushes and toothbrush handles can be structure as a whole, also can be flexible connection, be plugged with the bristle tuft of vertical arrangement on the head toothbrushes, the bristle tuft upper surface height of arrangement is identical and form a plane.Traditional method for brushing teeth is after putting into the oral cavity with the hair end face of above-mentioned toothbrush, aligned growth direction along tooth moves back and forth up and down, though this kind method than move left and right science some, but because of the head toothbrushes upper surface is the plane, and general bristle upper surface width is often greater than the width of tooth, and the bristles that makes side can injure gum, many for this reason oral cavity experts and doctor actively advocate the method for brushing teeth of employing science, promptly except when brushing teeth with toothbrush along the aligned growth direction of tooth moves, be also noted that when brushing tooth, toothbrush is brushed from top to bottom, during the brush lower tooth, toothbrush is brushed from lower to upper in order to the dirty thing of removing between backlash, when promoting this science and brushing teeth, it is the problem that the bristles on plane can injure gum that traditional toothbrush exists fit bad and upper surface of head toothbrushes upper surface and dental surface apparently, adds owing to the space in oral cavity is limited, bring some inconvenience to toothbrushing person, also influenced popularizing of this science method for brushing teeth.

The purpose of this utility model is to overcome the shortcoming that above-mentioned toothbrush exists, provide a kind of when brushing teeth the head toothbrushes upper surface can fit intactly with dental surface, the bristle tuft of dual-side is difficult for injuring the toothbrush of gum.

To achieve these goals, the utility model adopts following technical scheme: this toothbrush is the same with existing ordinary toothbrush, this toothbrush comprises head toothbrushes and toothbrush handles, head toothbrushes and toothbrush handles can be structure as a whole, also can be flexible connection, be plugged with the bristle tuft of vertical arrangement on the head toothbrushes, different is the middle bristle tuft height of planting and arranging, two to be close to the side bristle tuft low, and the bristle upper surface forms an arc convex surface.When using this toothbrush to brush teeth, bristle is faced toward tooth, dental surface contact with the bristle of arc convex surface and and bristle arc convex surface tangent line between shape in an angle, when brushing tooth, the lower side of head toothbrushes can be faced toward last tooth root, at this moment twist wrist on one side slightly, make the axial rotation of the upper surface of head toothbrushes around toothbrush handles, to upper teeth lower end move on one side.Vice versa, during the brush lower tooth, the upper side edge of head toothbrushes can be faced toward tooth root down, on one side slight twisting wrist, making the axial rotation of the upper surface of head toothbrushes around toothbrush handles, move to the lower teeth upper end on one side, and like this brushing teeth repeatedly can be finished the cleaning of tooth.

Because the utility model has adopted middle bristle tuft height, two are close to the low plant structure of side bristle tuft, the bristle upper surface is an arc convex surface, make the tangent line of dental surface and bristle upper end arc convex surface that one angle be arranged, and not the reason head toothbrushes to be close to the side bristle tuft contour and injure gum with middle bristle tuft, use this toothbrush can meet the method that dentist praises highly preferably and brush teeth.

Below in conjunction with accompanying drawing the utility model is described in further detail:

Fig. 1 is existing ordinary toothbrush schematic diagram.

Fig. 2 is the utility model toothbrush schematic diagram.

Fig. 3 is that the utility model bristle contacts schematic diagram with the tooth face.

Shown in Fig. 2-3, this toothbrush 1 comprises head toothbrushes 2 and toothbrush handles 3, head toothbrushes 2 can be structure as a whole with toothbrush handles 3, also can be flexible connection, be plugged with the bristle tuft of vertical arrangement on the head toothbrushes 2, middle bristle tuft 23 to two is close to the bristle tuft 21 of side, 24 height, as adopt five row bristle tuft, a row brush pieces height then, two are close to the side bristle tuft takes second place, the edge bristle tuft is minimum, if adopt four rows' bristle tuft, and then middle two row brush pieces height, two are close to the side bristle tuft takes second place, make the upper surface of head toothbrushes 2 roughly be arc convex surface 22 in a word, when brushing teeth, when the upper end arc convex surface 22 of head toothbrushes 2 contacts with tooth 4, tooth 4 surfaces can form an angle α with the tangent line of the arc convex surface 22 of bristle, make bristle arc convex surface 22 progressively to fit to the bristle of centre and the surface of tooth from the bristle that is close to side when twisting toothbrush 1.When brushing tooth, the following side bristle tuft 24 of being close to of head toothbrushes 2 can be faced toward tooth root, at this moment twist wrist on one side slightly, make the axial rotation of the upper end arc convex surface 22 of head toothbrushes 2 around toothbrush handles 3, to upper teeth lower end move on one side.Vice versa, during the brush lower tooth, the last side bristle tuft 21 of head toothbrushes 2 can be faced toward tooth root down, on one side slight twisting wrist, making the axial rotation of the upper end cambered surface 21 of head toothbrushes 2 around toothbrush handles 3, move to the lower teeth upper end on one side.Especially when the grinding one's teeth in sleep of both sides up and down in brush oral cavity, 23 pairs of upper surfaces of grinding one's teeth in sleep 41 of the middle bristle tuft of also available head toothbrushes 2 are brushed and are gargled, and this is that ordinary toothbrush is difficult to accomplish.
