RU63674U1 - CLEANING HEAD FOR DENTAL BRUSH - Google Patents

Abstract

The utility model relates to toothbrushes. To radically reduce trauma, a toothbrush cleaning head is proposed, which contains a bearing base, along the perimeter of which are located elastomer fibers grouped into a single ring structure, and a polymer bristle is concentrated in the central part, which is mounted on a separate movable platform, spring-loaded from the side opposite to the bristles and having the ability to move along the axis of the bristles, as well as tilt with respect to the axis of the bristles in all directions. At the same time, there can be several moving platforms with bristles, part of the bristles can be fixed on the moving platform, and the other part on the supporting base. Instead of a spring, another elastic material may be used. In addition, the bristles installed on different moving platforms can also be made of different polymer material.

Description

The present utility model relates to toothbrushes.

Known cleaning heads of the most common manual toothbrushes (http://www.oral-b.ru/), consisting of a base on which a nylon bristle is mounted. In the “Oral-B Cross Action Vitalizer” toothbrush model, 4 villi of 2 mm diameter elastomer located independently from each other at a distance of 3 mm are made along the edges of the base with bristles and the bristle itself is trimmed at different levels.

The curly brushing of the bristles, used by most manufacturers of toothbrushes, allows them to make the bristles adaptable to the relief of the dentition. Long bristles should penetrate the interdental spaces and clean them. However, in reality, it is the presence of these bundles of long bristles that makes the cleaning head more dangerous for the gums, as it creates the best conditions for damaging the gum tissue, opening the gingival pocket and introducing the infection into its depths. At the same time, rare elastomer fibers, covering only part of the bristles around the perimeter, do not completely prevent the strong bending of long nylon bristle threads and their penetration into the gingival pocket.

Closest to the design we offer is a cleaning head for a toothbrush (Decision on the grant of a patent for utility model No. 2006132799/22 (035683), Kuznetsov V.V., Gonets V.N., received November 9, 2006), containing a bearing base and a polymer bristle fixed on it, which is concentrated in the central part of the base, and along the perimeter of the base there are separate or combined into a single cellular structure hollow villi from an elastomer with holes at the free end, and the villi have different lengths and the depth of the holes

is 1-7 mm, mainly 3-5 mm. In addition, the holes can have an oval, rectangular, sectoral or hexagonal cross-section, and holes of different shapes, sizes and depths can be simultaneously present in the cellular structure.

Said cleaning head does indeed injure the gums less than all other cleaning heads. An elastic hollow-fiber fence really prevents the nylon bristles from bending and prevents them from penetrating into the gingival pocket. But due to the tight connection of the base of the cleaning head and the bristles, there remains the possibility of its excessively high pressure on the gums due to excessive pressure on the brush by hand. The fact is that during brushing, a person naturally tries to press a section of the bristles of the cleaning head against the teeth and gums. It is almost impossible to independently control the force of the clamping bristles during cleaning due to the need to simultaneously make reciprocating movements. Therefore, gum damage does occur.

The objective of this utility model is to endow the bristles of the cleaning head with the property of adaptability to the relief of the dentition and to the force of pressure, which is designed to provide a radical reduction in the morbidity of the cleaning head of the toothbrush.

The problem is solved in that, as in the prototype, the cleaning head for the toothbrush contains a carrier base, in the central part of which the bristles are concentrated, and an annular structure of elastomer with villi is located around the perimeter, but, unlike the prototype, the bristles are mounted on a separate a movable platform, spring-loaded on the opposite side, and the villi can be made both hollow and without cavities.

At the same time, part of the bristles can be fixed on a moving platform, and the other part on a supporting base.

In addition, there can be several moving areas with bristles.

In addition, a different elastic material may be used instead of the spring.

And finally, the bristles on different moving areas can be made of different polymeric materials.

In the future, the essence of the utility model is illustrated by the description and drawings, which depict:

Figure 1 - two examples of the execution of the cleaning heads;

Figure 2 - cleaning head parsed;

Figure 3 - sectional view of the cleaning head;

Figure 4 - the displacement of the moving areas when adapting to an uneven surface.

The main elements of the proposed cleaning head for a toothbrush are a bearing base 1, inside of which one or more movable platforms 5 with a bristle 2 are installed, and an annular structure of elastomer 3 with villi 4 fixed along the perimeter of the bearing base 1. Each movable platform is spring loaded from the side opposite bristle spring 6.

In the process of brushing teeth, the ring of villi is a limiter to the approach of the cleaning head in the cleaned surface. When the cleaning head is pressed against the enamel surface, the elastomeric villi are pressed tightly against the tooth enamel or gum and massage the gums. The bristles located on the movable platforms, goes inside the cleaning head and exerts pressure on the surface to be cleaned, which is determined not by the human hand, but only by the force of the spring located behind the movable platforms. The softer the spring, the correspondingly weaker the bristle pressure on the surface being cleaned. Thus, no matter how much a person presses the cleaning head against the teeth and gums during brushing, he will not be able to damage

gum. In addition, the use of even stiff bristles, which in ordinary cleaning heads severely damage the gums, in the proposed head gives only a positive effect - increases the cleaning efficiency and extends the life of the cleaning head. It should be noted that moving platforms can not only move along the axis of the bristles, but also tilt in all directions, which ensures clear tracking of irregularities of the surface being cleaned.

The proposed cleaning head can be used both in a manual toothbrush and in conjunction with various electric drives, including a vibratory drive.

We have performed both of the presented options for cleaning heads for hand brushes. Tests on volunteers showed that the made toothbrushes are very pleasant and convenient to use. They brush their teeth most gently and painlessly, effectively remove plaque, completely do not damage the gums and do not cause any discomfort during brushing. In this case, the interdental spaces are cleaned no worse than when using conventional cleaning heads. Users noted a pleasant feeling of vigor of the gums arising as a result of their massage during the cleaning procedure.
