Description

Toothbrush transplant structure {Toothbrush transplant structure}

The present invention relates to a hair transplant structure, and particularly to a hair transplant structure used in a toothbrush head portion.

In everyday life, the application range of brushes (made of hair) is very wide. Commonly seen in everyday life are brooms and cleaning brushes of various sizes, as well as roller brushes, spring brushes, pad brushes, steel brushes, etc. Use dedicated brush products for different purposes and shapes. Toothbrushes are usually distinguished from the brush products described above because toothbrushes are used for cleaning purposes for personal hygiene and come into direct contact with the oral cavity. In addition, due to the above reasons, toothbrushes are used by everyone every day and must be replaced regularly, so the market demand for toothbrushes is far greater than that of other brush products. Manufacturing such toothbrushes with high demand with automated machinery is a main production method common in the art.

When manufacturing toothbrushes with automated machinery, it is important to fix the bristles to the surface of the toothbrush, and usually fix the bristles in a hair-flocking manner. A key point in manufacturing a implanted brush is to insert and fix the bristles into the implanted hole. In the conventional hair transplant structure shown in FIGS. 5 and 6, the toothbrush 9 is provided with a plurality of hair transplant holes 92 on the surface of the head 91, and a groove 920 for hair transplant operation is formed in the hair transplant hole 92. do. The groove 920 has a vertical inner wall surface, one end of which is the top opening 921 and the other end is the bottom surface of the groove 922, and the bristles 93 and the plate-like member 94 are inserted into the hair transplant hole 92 together.

Conventional toothbrushes typically use a material capable of integrally forming hair transplant holes on the surface of the bristles. In modern society, where awareness of environmental protection is increasing in recent years, the method of replacing conventional non-degradable materials with degradable materials or natural materials is increasingly recognized by consumers and has market value. However, if the hair transplanting operation is performed with a material that cannot be formed integrally with the hair transplant hole, drilling is necessarily required. For example, when the above-described hair transplant structure of the prior art performs a hair transplant operation, the bristles are relatively loosened or separated from the hair transplant hole due to the lack of pull-off adhesion of the bristles of the hair transplant hole, which not only lowers the cleaning effect of the toothbrush, but also reduces the cleaning effect of the toothbrush by the consumer. will also decrease its acceptability.

The main purpose of the present invention is to provide a bristle structure capable of increasing pull-off adhesion of a toothbrush to reduce defects such as falling off of bristles or loosening of bristles.

The hair transplant structure of the toothbrush according to the present invention for achieving the above object includes a plurality of hair transplant grooves and a plurality of bristle bundles, but the plurality of hair transplant grooves have an inclined passage downward rather than a cylindrical shape on the surface of the head. one end of the inclined passage is an upper hole located on the surface of the head and the other end is a lower surface located inside the head, and the area of the lower surface is smaller than the opening area of the upper hole; The plurality of bristle bundles are configured by bending each bristle bundle and inserting a metal sheet, and inserting the metal sheet into a groove for hair transplantation corresponding to the upper end of each hole on the head using the metal sheet. The bristle bundle is fixed to the base.

The inner wall surface of the above-described inclined passage is made of a continuous inclined surface and is connected between the upper hole and the lower surface.

The range of the angle between the inner wall surface of the aforementioned inclined passage and the vertical line is 1 to 20 degrees.

The distance from the upper hole to the lower surface is 1.5 to 6 mm.

The diameter of the upper hole described above is 1 to 3 mm.

The shape of the upper hole described above is one of circular, triangular, rectangular, square, hexagonal, elliptical, and rhombic.

The diameter range of the bristle bundle described above is 0.0254 to 0.30 mm.

The material of the head described above is a natural material.

The material of the head described above is either wood or bamboo.

The above-mentioned groove for hair transplantation is drilled in the head by a machine or laser method.

Referring to Figure 1, Figure 1 is an exploded view showing that the bristle structure is used in the toothbrush (1) in the present invention. As shown in FIG. 1, the toothbrush 1 includes a handle portion 10 and a head 11 in contact with the handle portion 10, and hair transplantation is performed on the head 11 by the hair transplant structure of the present invention. do.

The head 11 is provided with a plurality of hair transplant grooves 12 so that the bristle bundles 13 are inserted and fixed correspondingly. The groove 12 for hair transplantation is formed by an inclined passage 120 extending downward from the surface of the head 11, and as shown in FIG. 1A, one end of the inclined passage 120 is located on the surface of the head 11. The hole 121 and the other end is the bottom 122 located inside the head 11.

As shown in FIG. 2, between the opening of the upper hole 121 and the bottom surface 122, the inclined inner wall surface where the inclined passage 120 continues is in contact with each other, and the area of the lower surface 122 of the inclined passage 120 is It is smaller than the opening area of the upper hole 121, so that the inclined passage 120 has a passage structure in which the upper opening is large and the lower bottom surface is small.

During the hair transplanting operation, each bristle bundle 13 is configured in such a way as to be bent and inserted into the metal sheet 14, as shown in FIG. 1A, and the head 11 using the metal sheet 14 as shown in FIG. Corresponding to the position of the upper hole 121 on the surface, by inserting the bristle bundle 13 into the groove 12 for hair transplantation, as shown in FIG. fixed on

The hair transplant structure according to the present invention is suitable for use in a toothbrush 1 made of natural materials such as wood or bamboo, and has a large, non-cylindrical shape on the surface of the head 11 of the toothbrush 1 by machine, laser, or other methods. The bottom can process a small passage for hair transplantation, and the diameter of the open end of the hole located on the upper surface of the inclined passage 120 in the preferred embodiment is relatively large and the diameter decreases as it goes deeper into the inclined passage 120. lose Therefore, the diameter of the bottom surface 122 located at the deepest part is smaller than the diameter of the upper hole 121 located on the surface of the head 11 .

In the process of hair transplanting, the metal sheet 14 is inserted into the hair transplant groove 12 together with the bristle bundle 13 bent by an external force, and as shown in FIG. 1A, the metal sheet 14 is inserted into the head 11 ) When entering the top hole 121 of the surface, the surface of the head 11 near the top hole 121 is cut in the depth direction of the inclined passage 120 and enters the head, and the metal sheet 14 is not affected by external force. to form an incision 141 and fix the metal sheet 14 and the bristle bundle 13 together in the groove 12 for hair transplantation.

The metal sheet 14 is cut downward to the depth of the inclined passage 120 by an external force, and inserted until the bristle bundle 13 contacts the bottom surface 122 of the groove 12 for hair transplantation, and the incision is made downward. In the process of insertion, the inclined passage 120 has a smaller diameter as it goes down to the depth, so the bristle bundle 13 is gradually united and fixed to the lower surface 122, and also on the lower surface 122 of the inclined passage 120. Since the diameter of the metal sheet 14 is relatively small, the metal sheet 14 can cut and contact the inner area of the head 11 relatively more, so that the metal sheet 14 is more stably fixed inside the head 11, so that the bristle bundle (13) Increases pull-off adhesion.

In the figure, the upper hole 121 is circular, and since the continuous inner wall surface of the inclined passage 120 is formed to be inclined, the inner shape of the inclined passage does not represent a cylindrical shape. However, the upper hole 121 is not limited to a circular shape, and may have a shape such as a triangle, a rectangle, a square, a hexagon, an ellipse, or a rhombus as shown in FIGS. 4A to 4E.

Referring to FIGS. 3 and 4, the range of the angle θ between the inner wall surface of the inclined passage 120 and the vertical line of the hair transplant groove 12 is 1 to 20 degrees, and in the upper hole 121 of the inclined passage 120 The distance D between the bottom surfaces 122 is 1.5 to 6 mm.

The diameter of the upper hole 121 located on the surface of the head 11 is 1 to 3 mm, and the diameter range of each bristle bundle 13 is 0.0254 to 0.30 mm.

As a result of the actual measurement of the hair transplant operation, the separation prevention ability measured after applying the prior art cylindrical hair transplant groove and applying a brush head with a diameter of 0.1778 mm, a depth of 3.5 mm, and a surface diameter of 1.7 mm was 10 to 25 Newtons (N ), and the detachment prevention ability measured after applying the non-cylindrical hair transplant groove 12 in the present invention is 15 to 30 Newtons (N), which increases the bristles' detachment prevention ability, so that the bristles loosen or fall off the toothbrush surface. can reduce

The foregoing has been described as an example of a preferred and practicable method of the present invention, but this does not limit the scope of protection of the present invention. All simple substitutions or equivalent substitutions of components or means performed according to the technical means of the present invention should be construed as belonging to the scope of the registration claims of the present invention.
