Abstract

The utility model discloses a flexible type toothbrush, which comprises a handle. One end of the handle is a brush head which is provided with brush bristles, and particularly, the diameter of the brush bristle is 0.1 mm to 0.15 mm. Through large numbers of tests, the optimum diameter of the brush bristle and the matched range of the length of the brush bristle are obtained, and the utility model enables the ratio of bending recovery, the tensile strength and the elongation extent of breakage of the single brush bristle to reach the best state of material use. Due to one end of the brush bristle is made into a taper shape, the brush bristle have high flexibility and high elasticity, and is particularly suitable for production of flexible tooth brushes or various flexible brushes.

Description

The soft type toothbrush

Technical field:

The utility model belongs to a kind of toothbrush, but particularly a kind of oral cavity cleaning prevents tooth generation bacterial plaque and the bristle soft type toothbrush to tooth and gingival irritation.

Background technology:

Dental caries is the common disease in oral cavity; it also is a kind of disease that is widely current in the world; the World Health Organization has classified this dental caries as after the cancer cardiovascular disease the third is badly in need of the disease of keypoint control, and the control dental caries must from tooth grow go out, if protect improper; then can on tooth, accumulate food; produce bacterial plaque, form carious tooth gradually, so want to have the tooth of a bite health; also must set up conventional and correct tooth-brushing habit from little attention oral hygiene.But the toothbrush that is fit to children's use at present is less, in particular for the toothbrush in cleaning child oral cavity then still less, it is because people's intrinsic thinking, general gauze wiping child's the gum that mostly adopts, the poor effect of its cleaning, if adopt the toothbrush cleaning, be not fit to the toothbrush that the child makes but have, child's gum position is very delicate, tooth calcification deficiency, inorganic salts in the enamel are few, make that the hardness of dental surface is very low, even are uneven, if the toothbrush bristle that uses more firmly then can damage tooth and gum, and the elderly's tooth often has loosening situation, can not use the harder toothbrush of bristle, so need a kind of child of being highly suitable for and the elderly's toothbrush on the market.

Goal of the invention:

Goal of the invention of the present utility model provides a kind of child of being specially adapted to and the elderly's soft type toothbrush.

For reaching above-mentioned purpose, the utility model comprises toothbrush handle, and an end of toothbrush handle is that the diameter of the brush that is provided with bristle, especially bristle is 0.1mm～0.15mm.

The utility model adopts the bristle number of bristle filaments optimum diameter that draws through substantive test and the body brush length that matches with it; make crooked recovery rate, tensile strength and the extension at break amount of individual bristle body reach the best user mode of material itself; and owing to body brush one end ground be sharp cone distal; make bristle not only have high flexibility but also a high resilience; can effectively clean the food residual chip on tooth or gum; prevent to produce bacterial plaque and bristle to the stimulation damage of tooth and gum, take care of one's teeth and gum.Be particularly useful for the toothbrush that child and the elderly use.

Description of drawings: Fig. 1 is the structural representation of first embodiment of the present utility model.Fig. 2 is the structural representation of bristle of the present utility model.

The specific embodiment:

Referring to Fig. 1～Fig. 2, specific embodiment of the utility model is as follows:

The diameter of described bristle 2 is 0.1mm～0.15mm; Bristle 2 brush silk for grinding through melt-spun and chemical method, two end or an end all can be ground into sharp cone distal 4 or butt end 5 (round blunt shape), and the free end of bristle 2 is a sharp cone distal 4; The length of sharp cone distal is 2.5mm～5mm; Bristle 2 be not 0.1mm～0.15mm by the diameter in the section of grinding cross section, bristle 2 on the brush 3 is made up of the single bundle bristle that some bristles are bundled into for multi beam, the soft or hard degree of the bristle 2 on its brush 3 is subjected to body brush cross-sectional diameter size impact, if bristle 2 diameters surpass 0.15mm, then bristle is harder, the end of bristle 2 can stimulate gum, cause the damage of tooth and gum, if diameter is less than 0.1mm, then bristle is too soft, causes the easy deformation in end of bristle 2, bending causes the end to lose its effectiveness, make the cleaning action variation, so the diameter range of bristle 2 is 0.1mm～0.15mm.

The free end of described bristle 2 is a sharp cone distal 4; Some bristles 2 are bundled into a single bundle bristle to be arranged in the peace jack base of brush 3, make the protruding peace jack base in an end of bristle 2, form free end, this free end grinds through processing and is sharp cone distal 4, because the free end of bristle 2 is a sharp cone distal 4, so, can make bristle tool soft feeling and can effectively arrive at boundary depression between tooth and tooth, tooth and the gum, effective cleaning teeth and gum.

The length of described sharp cone distal is 2.5mm～5mm; The cone length of bristle 2 is if surpass 5mm, then the rigidity of bristle or hardness reduce, cause the serviceability variation of toothbrush, if its cone length is shorter than 2.5mm, the rigidity or the hardness of bristle are strengthened, cause because bristle is hard to the damage of tooth and gum, so the scope of application of the cone length of bristle 2 is 2.5mm～5mm.

The preferable diameter of described body brush is 0.13mm～0.15mm; The diameter of body brush changes with diameter variation the ability influence that cleans one's teeth, if too reduce, causes the rigidity or the intensity variation of bristle, otherwise then strengthens, so protect the tooth effect for reaching preferable cleaning, its preferable diameter range is 0.13mm～0.15mm.

The length of described sharp cone distal 4 is 3mm; If when the diameter of body brush was 0.13mm～0.15mm scope, best suitable cone length can be 3mm with it.

In each bundle bristle 2 of described bristle 2, the free end of a part is a sharp cone distal 4, and the free end of a part is a butt end 5; Each single bundle bristle can all be made up of through being processed as tool bristle 2 identical or shape inequality the bristle 2 of its sharp cone distal and the bristle 2 or the two ends of tool butt end (round blunt shape), make the bristle that can have two kinds of end shapes in every single bundle bristle, the effect that cleans one's teeth and protect tooth with raising.

Described sharp cone distal 4 grows 2.5mm～5mm than butt end 5; In each single bundle bristle; bristle 2 height of tool sharp cone distal are provided the bristle 2 of butt end (round blunt shape); the sharp cone distal bristle of its raised area not only can play cleaning action but also can play and take care of one's teeth and the effect of gum; the bristle that prevents conventional butt end directly stimulates tooth and gum and the infringement that causes, and the suitable length scope of this raised area is 2.5mm～5mm.

Described sharp cone distal 4 grows 2.5mm～3mm than butt end 5; The height preferred values that sharp cone distal bristle 2 exceeds butt end bristle 2 is 2.5mm～3mm, if surpass this scope, then can cause result of use to reduce.

The utility model is through a large amount of tests, the body brush optimum diameter that draws reaches the number range of the body brush length that matches with it, make crooked recovery rate, tensile strength and the extension at break amount of individual bristle body reach the best user mode of material itself, and owing to body brush one end ground be sharp cone distal, make bristle not only have high flexibility but also a high resilience, be particularly useful for preparing flexibility toothbrush or various flexibility hairbrush.
