Description

Improved toothbrush grip structure

This creation relates to an improved toothbrush grip structure 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 twistable portion, the twistable portion has at least one connecting piece, and the thickness of the connecting piece is smaller than the thickness The thickness of the grip can change the angle of the brush head according to the pressure applied by the user. When the force of brushing exceeds a preset force value, the torsion portion can be elastically deformed to bend or rotate the brush head; when the force exceeding the preset value is removed , The torsionable part restores its original state by its own elastic force and returns the brush head to its original position; therefore, the torsionable part absorbs part of the brushing force of the tooth, thereby reducing the brushing force on the tooth surface and gums, and reducing the teeth and gums The damage caused.

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 FIG. 2 and FIG. 3 at the same time. The main point of this case is that a twistable portion 40 is connected between the handle 10 and the brush head 20, and the twistable portion 40 has at least one connecting piece 41. The thickness of the connecting piece 41 is smaller than the thickness of the grip 10. As shown in the first embodiment, the twistable portion 40 has four connecting pieces 41, and the thickness of each connecting piece 41 is smaller than that of the grip 10 The thickness and the distance between the connecting pieces 41 are provided, and the handle 10, the brush head 20 and the connecting pieces 41 are made of plastic material, and each connecting piece 41 can be further covered with an outer casing 42 The 50 series is a flexible material.

As shown in FIG. 3, when the toothbrush 1 is not in use, each connecting piece 41 assumes a normal state without being bent and deformed. 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 each connecting piece 41 is subjected to a bending force. When the bending force is less than the critical force, each connecting piece 41 produces a slight bending deformation. At the same time, the elastic force of each connecting piece 41 that generates a slight amount of bending deformation wants to return to its original state and the force that drives the brush head 20 to pivot relative to the grip 10 reaches a moment balance, so that the brush head 20 stops pivoting relative to the grip 10.

In addition, as in the second embodiment shown in FIG. 4, the twistable portion 40 can also have a connecting piece 41 and a sleeve 42 covering the connecting piece 41, which can also provide the brush head 20 to bend relatively Fold or rotate deformation.

As shown in FIG. 5, when the user brushes his teeth with a force that may cause damage to the tooth surface or gums, the bending force of the connecting piece 41 is greater than the critical force. At this time, the connecting piece 41 is bent and deformed to a large extent. At the same time, the elastic force of the connecting piece 41 that is bent and deformed to a larger extent cannot be restored to its original state and the force that drives the pivoting of the brush head 20 relative to the grip 10 to achieve a moment balance, so that the brush head 20 continues to pivot relative to the grip 10; because of the connection The setting of the blade 41 allows the connection piece 41 to drive the brush head 20 to pivot up and down relative to the handle 10; it can also drive the brush head 20 to pivot about the handle 10, as shown in FIG. 5, even allowing the brush head 20 to face The grip 10 forms a 360 degree rotation.

In this creation, the twistable part 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 twistable part absorbs part of the brushing force of the tooth, thereby reducing the bearing on the tooth surface and gums Brushing power reduces the damage to teeth and gums, and also extends the life of toothbrushes.

In the above embodiment, the connecting piece 41 is a rod-shaped configuration, and as shown in FIGS. 2 and 4, the rod-shaped configuration is straight; or as shown in FIGS. 7 and 8 As shown, the rod-shaped configuration has at least one protruding convex rib 43, and the outer casing 42 has at least one opening 421 relative to the convex rib 43, so that part of the surface of the convex rib 43 is exposed, as shown in the figure In the illustrated embodiment, the rod-shaped configuration has four ribs 43 and is slightly cross-shaped. On the other hand, the outer casing 42 has four openings 421.
