Description

Toothbrush grip improvement

This creation relates to an improved toothbrush handle that can change the angle of the brush head as the user applies pressure.

According to the press, the cleaning of the oral cavity is closely related to the health of the human body. People often use toothbrushes, mouthwashes and dental floss to clean the oral cavity. Among them, because the convenience of using the toothbrush is a basic tool for maintaining oral hygiene, the bristles of the toothbrush can conform The curvature of the teeth can extend into the interdental space between the teeth to clean the residual food in the interdental space. It can avoid the growth of bacteria in the food residue and the oral cavity to maintain oral hygiene and reduce the occurrence of oral diseases.

In order to maintain the health of the oral cavity, I work hard every morning and evening, and I hope that the teeth can be cleaned as much as possible. It is best to let the tooth decay never find the door. However, anything is too much. The research report points out that if you brush your teeth too hard, it may cause damage to the tooth surface and gums, but increase the risk of tooth decay and periodontal disease. In general toothbrushes, the handle and the brush head are integrally formed, and the angle between the handle and the brush head is a fixed value; when the brush head exerts pressure on the user's teeth, or the applied pressure exceeds a preset force value The angle between the grip and the brush head is still at a fixed angle, so that excessive force will cause damage to the teeth and gums, and make the user want to target specific dirty parts (such as stuck in (The residue in the tooth gap) strengthens the cleaning. The toothbrush cannot meet the user's need for cleaning with greater force, and the excessive force causes the brush head to press the bristles on the teeth or gums, shortening the service life of the bristles.

In view of this, this creation provides an improved toothbrush grip that can change the angular position of the brush head as the user applies pressure, for its main purpose.

The toothbrush of this creation includes a grip and a brush head; wherein, the grip and the brush head are connected by a torsion piece, and the torsion piece forms at least one rotation with the center of the longitudinal direction as a rotation axis, The angle position of the brush head can be changed according to the pressure applied by the user. When the tooth brushing force exceeds a preset force value, the torsion piece generates elastic deformation to bend the brush head; when the force exceeding the preset value is removed, the torsion piece can pass through its own The elastic force restores the original state and returns the brush head to its original position; therefore, the twisting piece can absorb part of the brushing force, thereby reducing the brushing force on the tooth surface and gums, reducing the damage to the teeth and gums, and can also be extended Toothbrush life.

According to the above technical feature, the torsion piece has first and second connection portions and at least one torsion portion between the first and second connection portions.

According to the above technical features, the first connection portion is connected to the grip, the second connection portion is connected to the brush head, and the torsion portion is formed by the first connection portion rotating toward a rotation axis.

In order to facilitate the examiner to understand the technical characteristics, content and advantages of this creation and the effects it can achieve, I hereby combine this creation with the drawings and explain in detail in the form of expressions of the embodiments, and the drawings used therein, which The main purpose is only for illustration and auxiliary instructions, and may not be the true proportion and precise configuration after the implementation of the creation, so it should not be interpreted and limited to the relationship between the proportion and configuration of the attached drawings, and the scope of the rights of the creation in the actual implementation. He Xianming.

Please refer to FIG. 1 for a perspective view of the structure of the toothbrush in this creation. The toothbrush 1 of this creation includes a grip 10 and a brush head 20. A plurality of bristles 30 are provided on one side of the brush head 20.

Please refer to Figure 2 and Figure 3 at the same time. The main point of this case is that: a twist piece 40 is connected between the grip 10 and the brush head 20, and the twist piece 40 is centered on its length The rotation axis 44 forms at least one rotation, and the thickness of the torsion piece 40 is smaller than the thickness of the grip 10, and the grip 10, the brush head 20, and the torsion piece 40 are made of plastic; wherein, the torsion piece 40 It has first and second connecting parts 41 and 42 and at least one twisting part 43 between the first and second connecting parts 41 and 42. In the embodiment shown in the figure, the first and second connecting parts 41 There is a torsion portion 43 between 42 and 42, the first connection portion 41 is connected to the grip 10, the second connection portion 42 is connected to the brush head 20, and the torsion portion 43 is connected by the first connection portion 41 rotates toward a rotation axis 44 located at the center in the longitudinal direction.

As shown in FIG. 3, when the toothbrush 1 is not in use, the twist piece 40 is in a normal state without being deformed by bending. When the user uses the toothbrush 1 to brush his teeth, the bristles 30 of the brush head 20 are subjected to a force that pivots the brush head 20 relative to the grip 10, and thus the torsion piece 40 is subjected to a bending force. When the bending force is less than the critical force, the torsion piece 40 produces a slight amount of bending deformation. At the same time, the elastic force of the torsion piece 40 which generates a slight amount of bending deformation and the force to drive the brush head 20 to pivot relative to the grip 10 achieves a moment balance, so that the brush head 20 stops pivoting relative to the grip 10.

As shown in FIG. 4, when the user brushes his teeth with a force that may cause damage to the tooth surface or gums, the bending force of the torsion piece 40 is greater than the critical force. At this time, the twist piece 40 is bent and deformed to a large extent. At the same time, the elastic force of the torsion piece 40 that generates a large amount of bending deformation cannot be restored to its original state, and the force that drives the brush head 20 to pivot relative to the grip 10 cannot be momentally balanced, so that the brush head 20 continues to pivot relative to the grip 10; 1. The arrangement of the second connecting portions 41, 42 and the twisting portion 43 allows the torsion piece 40 to drive the brush head 20 to pivot up and down relative to the handle 10 on the axis of rotation; it can also drive the brush head 20 relative to the handle 10 about the axis of rotation Pivot, as shown in Figure 5.

Furthermore, the torsion piece 40 is further covered with an outer casing 50. As shown in FIG. 1, the outer casing 50 is made of flexible material.

In this creation, the twisting piece is connected between the handle and the brush head, and the angle of the brush head can be changed according to the pressure applied by the user. The twisting piece can absorb part of the brushing force, thereby reducing the brushing on the tooth surface and gums Strength, reduce the damage to teeth and gums, and also extend the life of toothbrushes.
