Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a toothbrush, and more particularly, to a toothbrush whose bristle bed can be easily replaced.

[Conventional technology and problems]

It is said that after using a toothbrush for about two weeks, the brittle begins to deform, and if it is used for a month, its ability to remove plaque deteriorates significantly. Therefore, it is recommended that you replace your toothbrush with a new one every month.

However, even with toothbrushes that have been used for a long period of time, although the brittle may be deformed, there are often no problems with the handle. Therefore, it is sufficient to replace only the part of the bristle bed in which the brittle is implanted, and from this point of view, various toothbrushes have been proposed that allow the part of the bristle bed to be replaced. In such toothbrushes, it is considered most important to increase the strength of the joint between the bristle bed and the handle, and from this point of view, toothbrushes using metal for the joint have been proposed. More specifically, as disclosed in Japanese Utility Model Application Publication No. 54-98367, a groove is provided around the tufting table, a piano wire is applied to this groove to hold the tufting table, and the ends of the piano wire are There is a toothbrush that is inserted into the handle. It is possible to replace the bristle bed with this toothbrush, but when replacing it, you must first pull out the end of the piano wire from the handle and push the piano wire holding the bristle bed apart from side to side. However, there is a drawback that the replacement work is extremely complicated.

[Means for solving problems]

As a result of intensive research to solve the above-mentioned drawbacks of conventional toothbrushes, the inventors of the present invention discovered a toothbrush whose bristle bed can be replaced extremely easily and completed the present invention.

That is, the present invention provides a toothbrush in which the bristle-planting table is replaceable, and the bristle-planting table is made up of a bristle-planting table, an elastic rod-like object that grips the periphery of the bristle-filling table, and a handle in which both ends of the elastic rod-like object are embedded. consists of two parts that can be separated from each other, and both ends of the elastic rod are separately embedded in these two parts, so that the two parts of the grip handle are held together by the elasticity of the elastic rod. The purpose of the present invention is to provide a toothbrush with special characteristics.

[Effect]

The toothbrush of the present invention allows easy replacement of the bristle bed, and the reason for this will be explained with reference to FIGS. 1 and 2, which show one embodiment of the present invention. Note that the hair transplantation stand is not shown in these figures.

In FIG. 1, both ends 2 and 2' of an elastic rod-like object 1 that grips the periphery of the hair transplanting table are separately embedded in the grip handle 3, and the central part along the longitudinal direction of the grip handle 3 is , a notch 4 is provided for dividing the grip handle 3 into two. Therefore, when replacing the hair transplanting table, as shown in FIG.
3" to temporarily separate them, the rod-like object 1 will also be pushed outward and spread out, making it easy to replace the hair transplantation table. Once the replacement is complete, attach the handle to the handle. When the applied force is removed, the temporarily separated handles 3', 3'' are reunited due to the elasticity of the rod-shaped object 1. It is preferable that the contact surfaces of the grip handles 3' and 3'' fit into each other as shown in FIG.

The elastic rod-shaped object 1 mentioned here is various metals and plastics having energy elasticity. The cross-sectional shape of the rod is not limited to only a circular shape, but may also be rectangular, triangular, or the like.

Another embodiment of the toothbrush of the present invention is shown in FIGS. 4 and 5. In this example, the part of the handle in which one end 2' of the elastic rod-like object 1 is embedded is cut out so as to include the embedded part of the rod-like object 1, and this cut-out part 5 is reshaped into the grip handle as shown in FIG. This is intended to facilitate replacement of the tufting table by attaching and detaching it from the main body 3.
