Abstract

Disclosed is a toothbrush having tapered bristles, belonging to the technical field of daily necessities, wherein after rounding off the brush wire (1) of the toothbrush, the diameter of the brush wire (1) becomes thinner regularly from the middle to both ends, until the diameter of both ends reaches 0.01 mm-0.08 mm; after sanding the brush wire (1), the sharpening rate thereof reaches 90%-95%; and after tufting the toothbrush, a secondary rounding off processing on the rear end surface of the brush wire (1) is not needed. The toothbrush made using the brush wire (1) will have soft and comfortable tips, goes deep into the gaps between the teeth, will not hurt the gums and will have a better cleaning effect, and is especially suitable for special populations having bleeding gums and vulnerable gums and the like.

Description

a pointed bristled toothbrush

Technical field

The utility model relates to a toothbrush, in particular to a brush wire whose diameter is balanced and tapered from an intermediate position to both ends. It belongs to the technical field of daily necessities.

Background technique

Toothbrushes are the most common daily necessities. With the continuous improvement of people's living standards and quality of life, people pay more and more attention to the cleaning and health care of teeth. Toothbrushes made of pointed brush are becoming more and more popular in daily life because they are softer and have a better cleaning effect than traditional flat-head brushed toothbrushes. The traditional toothbrush bristles are all nylon filaments. After the hair is planted, the secondary end surface layer is rounded. If the sanding rate is not standard or uneven, the gums are easily damaged during brushing, which causes oral bleeding. The disease breeds.

Both CN200320120236.6 and CN200610037729.1 have invented a brush wire with a head or a head at one end of the cone, which are all cut into monofilaments, and the end portion is vertically immersed in a corrosive chemical solution. Corroded to the specified size, the toothbrush is implanted into the brush and then ground by a sanding machine. The polymer material used in CN200320120236.6 is polyamide, etc., and the polymer material used in CN200610037729.1 is polybutylene terephthalate, polyethylene terephthalate or polybutylene terephthalate. And a mixture of polyethylene terephthalate.

Summary of the invention

In order to solve the above technical problem, the utility model provides a brush wire having a tapered and tapered end. After the toothbrush brush wire is rounded, the brush having the shape shown in FIG. 1 and having a length of 20-120 mm is prepared. The wire diameter is balanced and tapered from the intermediate position to the both ends.

The diameter of the brush wire used is 0.13-0.15 mm, and the diameter of the tip end of the wire after the rounding treatment is 0.01 mm to 0.08 mm. The toothbrush after the brushing of the brush wire does not need to be subjected to secondary rounding treatment on the surface of the tail end of the brush wire, and the sharpening rate of the brush wire after grinding is 90-95%.

The polymeric synthetic material can be made of a nylon material, particularly nylon 610.

The toothbrush thus produced does not require secondary sanding, and solves the problem that the sanding rate is not up to standard or uneven. The toothbrush made of the brush wire can not only penetrate the teeth without hurting the gums, but also has a soft and comfortable tip.
