The brushing head includes a brush member integrally extended at the brushing end of the handle, a plurality of brushing bristles vertically extended from a front portion of the brush member to form a top brushing surface of the brushing bristles, and a plurality of inclined bristles upwardly extended from the brush member, in such a manner that the inclined bristles form a predetermined inclined angle with the brushing surface of the brushing bristles, so that the inclined bristles are adapted to substantially brush teeth and gum of a user.
Description
- 1. Field of Invention
- The present invention relates to a toothbrush, and more particularly to a toothbrush comprising a plurality of specifically inclined brushing bristles for effectively cleaning the user's teeth.
- 2. Description of Related Arts
- Toothbrushes are extremely important in that they are capable of removing dirt in the user's gum and teeth for preventing tooth decay and certain oral diseases. A conventional toothbrush comprises a handle, and a brush head provided on a brushing end of the handle, wherein a brush head comprises a plurality of brushing bristles movably extending at the brush head in such a manner that a user is able to hold on the handle and brush his teeth by the brushing bristles.
- There are several disadvantages for this kind of conventional toothbrush. First, almost all of the brushing bristles are vertically extending at the brush head so that when the user uses the toothbrush, the angle between the brushing bristles and the user's teeth may not be such that the brushing bristles can effectively remove the dirt trapped in the user's gum. Consequently, even though the user brushes his teeth in a regular basis, there is a high chance that the user may nevertheless develop tooth decay simply because the toothbrush fails to clean the dirt in the user's gum.
- In order to achieve effective brushing of teeth, researches have shown that the toothbrush should brush the teeth at approximately 45 degrees. Conceivably, it is impossible for everyone to follow this proper brushing practice. The result is that conventional toothbrushes are generally ineffective in preventing tooth decay.
- As a matter of fact, there exist automatic toothbrushes which are electrically driven to brush the users' teeth. Although these toothbrushes are in general more effective in prevent tooth decay than conventional manual toothbrushes, they are far more expensive than conventional toothbrushes and many people simply cannot afford to buy one. Thus, those who are still using conventional manual toothbrushes are at risk from tooth decay and other associated oral diseases.
- A main object of the present invention is to provide a toothbrush comprising a plurality of specifically inclined brushing bristles for effectively cleaning the user's teeth so as to optimally prevent tooth decay and other associated oral diseases.
- Another object of the present invention is to provide a toothbrush which is capable of brushing a user's teeth at an optimal angle without needing the user's special tuning of the handle's angle.
- Another object of the present invention is to provide a toothbrush which does not involve complicated mechanical and electrical components so as to minimize the manufacturing cost and the ultimate selling price of the present invention.
- Accordingly, in order to accomplish the above objects, the present invention provides a toothbrush, comprising:
- an elongated handle having a brushing end; and
- a brushing head which comprises a brush member integrally extended at the brushing end of the handle, a plurality of brushing bristles vertically extended from a front portion of the brush member to form a top brushing surface of the brushing bristles, and a plurality of inclined bristles upwardly extended from the brush member, in such a manner that the inclined bristles form a predetermined inclined angle with the brushing surface of the brushing bristles, so that the inclined bristles are adapted to substantially brush teeth and gum of a user.
- These and other objectives, features, and advantages of the present invention will become apparent from the following detailed description, the accompanying drawings, and the appended claims.
-
FIG. 1 is a perspective view of a toothbrush according to a preferred embodiment of the present invention. -
FIG. 2 is a side view of the toothbrush according to the above preferred embodiment of the present invention. -
FIG. 3 is a schematic diagram of the toothbrush according to the above preferred embodiment of the present invention. - Referring to
FIG. 1 toFIG. 3 of the drawings, a toothbrush according to a preferred embodiment of the present invention is illustrated, in which the toothbrush comprises anelongated handle 10 having aholder end 11 and a brushingend 12, and a brushinghead 20. - The brushing
head 20 comprises abrush member 21 integrally extended at the brushingend 12 of thehandle 10, a plurality ofbrushing bristles 22 vertically extended from a front portion of thebrush member 21 to form a top brushingsurface 221 of the brushing bristles, and a plurality ofinclined bristles 23 upwardly extended from thebrush member 21, in such a manner that theinclined bristles 23 form a predetermined inclined angle with the brushingsurface 221 of thebrushing bristles 22, so that theinclined bristles 23 are adapted to substantially brush teeth and gum of a user. - According to a preferred embodiment of the present invention, the
inclined bristles 23 are extended from thebrush member 21 in a side-by-side manner with respective to thebrushing bristles 22, wherein theinclined bristles 23 are inclined at 45 degrees with respective to the brushingsurface 221 so as to optimally brush inner sides of the user's teeth and the user's gum. - It is important to point out that a height of each of the
inclined bristles 23 is preferably greater than a height of each of thebrushing bristles 22 so that a top portion of each of theinclined bristles 23 is inclined at (180 degrees minus 45 degrees) 135 degrees with respect to the top brushingsurface 221 for substantially brushing the user's teeth and gum. - As a result, a top portion of each of the
inclined bristles 23 forms aninclined surface 231 which has an angle of inclination at approximately 135 degrees with respect to the brushingsurface 221. According to the preferred embodiment of the present invention, thebrushing bristles 22 and theinclined bristles 23 are made of durable yet flexible materials extended from thebrush member 21 for brushing the user's teeth. - Referring to
FIG. 2 of the drawings, theinclined bristles 23 are divided into a first and asecond bristles row brushing bristles 22 so that the user may easily brush the gap between his teeth and the gum. In other words, theinclined bristles 23 are extended from two side portions of thebrush member 21 while thebrushing bristles 22 are extended at a mid portion of thebrush member 21 to be sandwiched by theinclined bristles 23. Moreover, a width of thebrushing bristles 22 is larger than a height of a user's teeth so that thebrushing bristles 22 are adapted to substantially brush the user's teeth. - The operation of the present invention is as follows: the user simply needs to hold the
holder end 11 of theelongated handle 10 and brush his teeth and gum by the brushinghead 21. Since theinclined bristles 23 is inclined at 45 degrees with respect to horizontal, theinclined bristles 23 are adapted to effectively brush a gap between the teeth surface and the corresponding user's gum so as to effectively remove dirt from the user's teeth. - From the foregoing descriptions, it can be shown that the above objects of the present invention are substantially accomplished. The present invention provides a toothbrush which comprises the plurality of specifically
inclined brushing bristles 23 for effectively cleaning the user's teeth so as to optimally prevent tooth decay and other associated oral diseases. The user of the present invention does not need to turn his arm at a bizarre orientation in order to effectively brush his or her teeth. - One skilled in the art will understand that the embodiment of the present invention as shown in the drawings and described above is exemplary only and not intended to be limiting.
- It will thus be seen that the objects of the present invention have been fully and effectively accomplished. It embodiments have been shown and described for the purposes of illustrating the functional and structural principles of the present invention and is subject to change without departure from such principles. Therefore, this invention includes all modifications encompassed within the spirit and scope of the following claims.
