Background technique

As we all know, the cleanliness of teeth plays a vital role in maintaining dental health, maintaining oral hygiene and health, as well as the health of the entire digestive system, maintaining a good appearance of the instrument, and so on. Traditional toothbrushes generally take the form of unidirectional bristles, that is, all bristles are set in one direction and the same direction, and the plane formed by the upper end of the bristles is used to clean the teeth. However, because the teeth themselves have a certain curvature, therefore, Such a one-way bristled toothbrush does not clean teeth well, especially the gap between teeth and teeth. In order to solve the above problems, people have invented spherical, wavy, and liquid toothbrushes, but the final effect is not very satisfactory. For example, a wavy toothbrush appears on the market. The improvement lies in that the bristles are not even in height. Instead, it is set as follows: the part of the upper end of the bristles for contact with the teeth is wavy or jagged from the side, so that the cleaning effect is improved, but the cleaning effect on the teeth is still not good enough, and these toothbrushes Both have the following disadvantages: First, when using these toothbrushes to clean their teeth, the outside and inside of the teeth are cleaned separately, which increases the brushing time. Second, when cleaning the inside of the teeth, usually only the toothbrush can be backhanded. The head extends into the inside of the tooth and the bristles are cleaned against the inside of the tooth. Due to the inconvenience of backhand use, the inside of the tooth is not thoroughly cleaned, especially the inside of the tooth deep in the mouth cannot be cleaned well, and sometimes the tooth is washed May accidentally extend the brush head too far into the inner wall of the mouth To unexpected shocks.

The object of the present invention is to provide a toothbrush, which can simultaneously clean the outside and inside of the teeth, thereby reducing the brushing time, and cleaning the teeth and the interdental well, without the need to backhand the bristles to the inside of the teeth for cleaning. Easy to use. Summary of the invention

In order to achieve the above object, the present invention provides a toothbrush, which includes a toothbrush head and a toothbrush handle.

The outer plane of the bristle seat is narrow. '' The working principle and effect of the present invention are as follows: Since the inner sides of the two bristle bases provided with bristles face each other at an angle, and the outer ends of the bristles on the two bristle bases are combined into a concave portion that can accommodate teeth, And the longitudinal direction of the two bristle holders is basically perpendicular to the handle of the toothbrush. When in use, place the concave portion "on the teeth" so that the The bottom is facing the upper end of the tooth. In this way, the two sides of the concave part are exactly opposite the inner and outer sides of the tooth. When cleaning, simply move the toothbrush handle back and forth to make the bristles on both sides of the concave part simultaneously. Move back and forth on both the inner and outer sides of the tooth, so that the inner and outer sides of the tooth can be cleaned at the same time, saving time for brushing, and cleaning the inner side of the tooth without extending the toothbrush to the inside of the mouth, so it is easy to use. In addition, the bottom and two sides of the recessed portion simultaneously clean the upper end of the teeth and both the inner and outer sides, which can effectively clean the teeth and the teeth.

When the two bristle holders are respectively connected to the toothbrush handle at their roots, the two bristle holders may gradually expand from small to large from their roots adjacent to the toothbrush handle to their respective outer ends. The outer ends of the bristles of the two bristle holders form a concave portion. At this time, the upper and lower teeth can be cleaned separately when cleaning the teeth.

When two bristle holders are respectively connected to the toothbrush handle at the middle portion, so that each bristle holder has two outer ends, the two bristle holders are located from the middle part connected to the toothbrush handle to the toothbrush handle. The respective outer ends of the same side are gradually expanded from small to large. The outer ends of the bristles on the two bristle holders are combined on both sides of the toothbrush handle to form a concave portion that can accommodate teeth. At this time, the upper and lower teeth can be placed into the concave portions on the upper and lower sides respectively, so that the upper and lower teeth can be washed at the same time, which further shortens the brushing time.
