Toothbrush combination structure

A toothbrush combination structure, in particular, a surface of one side of the brush head is concavely provided with a positioning groove for positioning with the frame of the handle, and the other side is provided with a notch for abutting against the frame body, so that the brush head and the handle are combined. A toothbrush that can replace the brush head and is easy to assemble for the convenience of use and environmental protection.

Generally, the toothbrush is mainly formed by integrally forming a brush handle and a brush head connected to one end of the handle. Therefore, after the toothbrush of the above structure is used for a long time, in order to avoid hygiene concerns, the whole set of toothbrush is usually directly discarded. Replacement with a new toothbrush for use, in addition to causing serious waste of resources, discarded toothbrushes discarded each year will cause environmental pollution, which is not conducive to environmental protection.

Therefore, how to solve the above-mentioned problems and shortcomings is the subject of research and development that the relevant industry is eager to develop.

The main purpose of the present invention is to use the positioning grooves and the notches respectively disposed on the two sides of the brush head to respectively position and abut the positioning portions and the abutting on the two sides of the frame when the brush head is embedded in the frame of the handle. The brush head is combined with the handle to form a toothbrush that can replace the brush head, and is easy to assemble, and is convenient to use and environmentally friendly.

In order to achieve the above object, the toothbrush assembly structure comprises a brush handle and a brush head, the handle has a handle body and a frame body disposed at one end of the handle body, and the frame body is formed to be abutted on a side of the handle body. a positioning portion is formed on the other side; the concave side of the brush head has a positioning groove on the concave side, the other side is provided with a notch from the bottom to the upper side, and the positioning groove communicates with the missing groove, and the positioning portion of the brush handle is positioned at the positioning In the groove, the abutting portion of the handle abuts against the notch.

In the above-mentioned toothbrush assembly structure, the inner surface of the abutting portion of the handle frame body is formed with an inclined surface inclined toward the positioning portion, and the notched side wall of the brush head is inclined toward the positioning groove, and the notched side wall is abutted against the inclined surface surface.

In the above-mentioned toothbrush assembly structure, the end of the inclined surface of the handle frame body obliquely extends away from the positioning portion with a holding surface, and the end of the notched side wall of the brush head extends obliquely away from the positioning groove. The stop surface and the stop surface are attached to the holding surface.

Referring to the first to third figures, it can be clearly seen from the figure that the toothbrush assembly structure comprises a handle 1, a brush head 2 and a bristles 3, wherein:

The handle body 1 has a handle body 11 and a frame body 12 integrally formed at one end of the handle body 11. The frame body 12 is formed with an abutting portion 121 on the side closer to the handle body 11, and a positioning portion 122 is formed on the other side. The inner surface of the abutment portion 121 is formed with an inclined surface 123 inclined toward the positioning portion 122, so that the inside of the frame body 12 is formed into an inverted ladder shape having an upper width and a lower width, and the end of the inclined surface 123 extends obliquely away from the positioning portion 122. The holding surface 124.

A positioning groove 21 is recessed on one surface of the brush head 2, and a notch 22 is formed on the other side from the bottom to the top. The positioning groove 21 is connected to the notch 22 and has a groove bottom 211 and two sides of the groove bottom 211. The second slot wall 212 has a bottom surface 221 and a side wall 222. The side wall 222 is inclined toward the positioning slot 21, and the end of the side wall 222 extends obliquely away from the positioning slot 21 with a stop surface 223.

The bristles 3 are provided on the surface of the brush head 2.

Referring to the fourth to eighth figures, it can be clearly seen from the figure that the present invention is used to first place the brush head 2 with one side of the positioning groove 21 into the frame 12 of the handle 1. The positioning groove 21 is adjacent to the groove wall 212 of the bristles 3 against the upper surface of the positioning portion 122 of the frame body 12, and the other side of the brush head 2 provided with the notch groove 22 is embedded in the frame along the inclined surface 123 of the frame body 12. 12, the side wall 222 of the notch 22 is abutted against the inclined surface 123 of the frame 12, and the stop surface 223 is abutted against the holding surface 124, and the bottom surface 221 of the notch 22 abuts against the abutment The upper surface of the portion 121 prevents the brush head 2 from being disposed on one side of the notch 22 to be disengaged from the frame 12, and the positioning groove 21 on the other side of the brush head 2 is away from the groove wall 212 of the bristles 3 and abuts against the notch 22 The inner portion of the positioning portion 122 is abutted against the bottom surface 211 of the positioning groove 21, and is engaged with the positioning groove 21 to form a positioning, so that the brush is placed on the bottom surface of the positioning portion 122. The head 2 is tightly coupled to the handle 1.

Therefore, the present invention is to solve the problem of waste of resources and environmental problems caused by the replacement of the conventional toothbrush, and the key technology is to use the positioning groove 21 and the notch 22 respectively disposed on the two sides of the brush head 2, When the brush head 2 is inserted into the frame 12 of the handle 1, the positioning portion 122 and the abutting portion 121 on the two sides of the frame 12 are respectively positioned and abutted, so that the brush head 2 and the handle 1 are combined to form a replaceable brush. The toothbrush of the first 2 is easy to assemble and not easy to fall off, achieving convenient use and environmental protection.
