However, in the existing toothbrush, since the bristles are fixed to the side of the head and perpendicular to the head, the bristles cannot freely tilt or swing with respect to the head, and can only operate at a predetermined angle. The surface of the teeth or the space between the teeth cannot be accurately polished, and the back and narrow portions of the oral cavity cannot be brushed, so that the oral hygiene cannot be maintained.

The head of the toothbrush according to the present invention has a main body and a head member,
Among them, the main body is made of a hard material, and includes a plurality of cylinders, the cylinders are provided at intervals, and a flocking hole is recessed at one end of each cylinder, and two adjacent cylinders A connecting plate is provided between
The head member is made of a soft material, and is combined so as to cover each cylindrical body and connection plate of the main body.

In such a toothbrush head, it is preferable that a coupling portion is provided at one end of the main body, a plurality of cylindrical bodies are integrally formed at the coupling portion, and the cylindrical bodies are connected by the coupling portion.

In such a toothbrush head, it is preferable that a ring member is provided at one end of each cylindrical body having a flock hole.

In such a toothbrush head, it is preferable that a neck portion is extended to the coupling portion of the main body, and the head member is attached to the neck portion so as to cover a part of the coupling portion and the neck portion of the main body.

On the other hand, the head of the toothbrush according to the present invention has a main body and a head member,
Among them, the main body is made of a hard material, and includes a plurality of cylinders, the cylinders are provided at intervals, and a flocked hole is recessed at one end of each cylinder,
The head member may be made of a soft material and combined so as to cover each cylindrical body of the main body.

In the toothbrush according to the present invention, the cylinders in which the hairs of the head are planted are connected by thin connection plates, and the soft head member is combined so as to cover the cylinder and the connection plate. The body and hair can tilt and swing individually and freely. Therefore, when a user uses a toothbrush, the hair and cylinder of the head can brush their teeth while moving in different directions depending on the shape of the tooth, so that the plaque or dirt on the tooth surface or between the teeth can be removed. Can always keep teeth clean.

Further, in the head of the toothbrush according to the present invention, since each of the plurality of cylinders 11A is covered by the soft head member 20, each cylinder 11A and the bristles 30 freely and individually tilt or swing, The teeth can be brushed to every corner while moving in different directions.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. In addition, the following Example is only what showed the preferred embodiment of this invention, and the technical scope of this invention is not limited to the following Example itself at all.

As shown in FIGS. 1 and 2, the head of a toothbrush according to the present invention has a main body 10, a head member 20, and a plurality of bristles 30, and a neck portion 100 extends integrally at one end of the main body 10. The head member 20 is attached to cover the main body 10 and a part of the tip of the neck portion 100, and the bristles 30 are planted in the main body 10.

The main body 10 is made of a hard material such as plastic, and is manufactured by an existing molding technique such as a plastic injection molding technique. A neck portion 100 is integrally extended at one end of the main body 10. The main body 10 includes a plurality of cylinders 11. The cylinders 11 have a cylindrical shape in the vertical direction and are arranged at intervals, and a ring member 12 is provided at the upper end of each cylinder 11. A flocked hole 13 is recessed in the center of the upper end surface of each cylindrical body 11, and hair 30 is planted in the flocked hole 13. Furthermore, as shown in FIG. 4, a connecting plate 14 is provided between two adjacent cylinders 11, and the connecting plate 14 is a thin plate. These cylinders 11 can be connected by a connecting plate 14 to form a toothbrush.
Further, the connecting plate 14 connects a plurality of cylinders 11, and the cylinders 11 can freely tilt or swing. The connecting plate 14 of this embodiment is made of resin at the gate of the mold at the same time as the cylindrical body 11 is molded by putting resin in the mold.

As shown in FIG.2 and FIG.4, the coupling | bond part 15 is provided in the end of the main body 10 using the injection molding process, The several cylinder 11 is integrally formed in this coupling | bond part 15, These cylinders 11 are the following. The connecting portion 15 is connected, and the connecting portion 15 of the main body 10 and the neck portion 100 are integrally connected to each other by injection molding.

As shown in FIGS. 1 to 3, a head member 20 made of a soft material such as silicon is further formed by using secondary processing of injection molding so as to cover a part of the tip of the main body 10 and the neck portion 100. The head member 20 covers the cylinder 11 and the ring member 12 of the main body 10 and forms the same plane as the upper surface of the cylinder 11.
Further, as shown in FIGS. 5 and 6, the head member 20 is provided so as to cover the cylindrical body 11, the ring member 12, and the connecting plate 14, so that the coupling effect between the head member 20 and the main body 10 is achieved. Are better.

As shown in FIG. 1, the cylinders 11 in which the hairs 30 are planted are connected by thin connection plates 14, and the soft head member 20 covers the cylinders 11 and the connection plates 14. Thus, the cylindrical body 11 and the hair 30 can be individually and freely tilted or swung. Therefore, when the user uses a toothbrush, the head bristles 30 and the cylinder 11 are brushed while moving in different directions depending on the shape of the teeth, thereby removing plaque and dirt on the tooth surface or between the teeth. And keep your teeth clean.

As shown in FIGS. 7 and 8, in another embodiment of the head of the toothbrush according to the present invention, the plurality of cylinders 11A of the main body 10A are independently arranged at intervals, that is, existing A plurality of cylinders 11A are individually molded using the injection molding technique, and a flocking hole 13A for planting hairs 30 is formed at the center of the upper surface of each cylinder 11A.

Then, after the cylinder body 11A and the neck portion 100A are installed in the mold, secondary processing of injection molding is performed so that the head member 20 covers a part of the tips of the cylinder body 11A and the neck portion 100A. If formed, the head of the toothbrush of this embodiment is completed.
In this embodiment, since the plurality of cylinders 11A are each covered by the soft head member 20, the cylinders 11A and the hairs 30 freely and individually tilt or swing, and move in different directions. While washing the teeth.
