Abstract
The present invention relates to a rotary toothbrush as an improvement for the conventional toothbrush. The rotary toothbrush includes a toothbrush bar having a grip part (1), a neck part (2) and a head part (3). At least of rotary toothbrush plates (4, 5) can be installed on head part (3) of the toothbrush bar to rotate around the center shaft thereof. A plurality of toothbrush furs (8 a, 8 b, 8 c, 8 d, 8 e) which are arranged in regular group shapes are installed at several places on rotary toothbrush plates (4, 5). By varying plant-installation density, plant-installation height, or materials or strength of toothbrush firs (8), toothbrush furs (8) on rotary toothbrush plates (4, 5) generate a biased resistance between teeth upon brushing of teeth, and thus rotary toothbrush plates (4, 5) can be automatically rotated by generation of the biased resistance.
Description
- The present invention relates, in general, to toothbrushes and, more particularly, to an improvement in the structure of such a toothbrush to allow the bristles of the toothbrush to move on the teeth while generating different resistance forces against the teeth in accordance with positions of the bristles on the teeth, thus forcing a rotary bristle bed to be automatically rotated on the head of the toothbrush in either direction around its rotating shaft due to the different resistance forces, the rotary toothbrush thereby effectively and uniformly brushing the teeth even when a user horizontally brushes his teeth along the sets of teeth without brushing the teeth vertically.
- The teeth of the human body are arranged along two sets of teeth, or the upper and lower lows of teeth, which engage with each other. Since each of the upper and lower sets of teeth comprises a plurality of teeth regularly arranged along a horizontal arrangement, it is easy for people to horizontally brush the teeth along the sets of teeth in opposite directions. That is, such a horizontal tooth brushing action agrees with the natural posture of an arm holding the toothbrush while brushing the teeth, and allows people to brush their teeth without difficulty, and so the people unconsciously prefer the horizontal tooth brushing action of all other directional brushing actions.
- However, since a vertical slit is left between two teeth of each set of teeth, in addition to a plurality of microgrooves formed along the vertical grains of the enamel of each tooth, dental plaque is inevitably deposited in the vertical slits between the teeth and in the microgrooves of the enamels. It is almost impossible to effectively remove such dental plaque, deposited in the vertical slits between the teeth and in the microgrooves of the enamels, by the horizontal tooth brushing action. Therefore, most dentists advise users of typical toothbrushes to vertically, repeatedly and sequentially brush their teeth along the vertical slits between the teeth and the vertical microgrooves of the enamels to remove the dental plaque from the slits and microgrooves. However, such a vertical tooth brushing action is not natural for the human body, and so people are not likely to easily get the action into a habit. People, wanting to do such a vertical tooth brushing action, are forced to consciously perform the action each time they brush the teeth. Another problem, experienced in the vertical tooth brushing action, resides in that the action forces people to consume excessive time with difficulty to effectively or desirably brush the teeth.
- In an effort to overcome such problems experienced in the tooth brushing action using typical toothbrushes, a variety of electric toothbrushes have been proposed and used. The conventional electric toothbrushes are designed to automatically rotate the bristles of a toothbrush using electric power, thus allowing users to more easily brush their teeth. However, such electric toothbrushes are problematic in that they have excessive volume and excessive weight since they must be provided with means for electrically operating the bristles. In addition, the electric toothbrushes inevitably have a complex construction, and so they are likely to be easily and repeatedly broken, thus being required to be repeatedly repaired or forcing the users to purchase new toothbrushes. The conventional electric toothbrushes are operated by electric power of batteries, and so it is necessary to repeatedly change the batteries with new ones. Another problem experienced in the conventional electric toothbrushes resides in that they are expensive, thus forcing users to pay excessive money for the electric toothbrushes. Therefore, people do not generally use such electric toothbrushes.
- In addition, a toothbrush, having a rotatable disc-shaped bristle bed, has been proposed and used. In this toothbrush, a disc-shaped bristle bed is set in the head of the toothbrush such that the bristle bed is eccentrically rotatable relative to the head during a tooth brushing process. However, this toothbrush has a structural limit in that the disc-shaped bristle bed of the head is not allowed to smoothly perform its desired rotation relative to the head when a user horizontally brushes his teeth along the sets of teeth. In addition, the bristle bed is eccentrically rotated at a position excessively away from the central axis of the head of the toothbrush during tooth brushing process, and so the bristles and the bristle bed may come into undesired contact with other parts of the mouth to impact or injure the parts. It is also very difficult for the toothbrush to effectively brush desired parts of teeth.
- Accordingly, the present invention has been made keeping in mind the above problems occurring in the prior art, and an object of the present invention is to provide a rotary toothbrush, which allows its bristles to move on teeth while generating different resistance forces against the teeth in accordance with positions of the bristles on the teeth, thus forcing its rotary bristle bed to be automatically rotated on the head of the toothbrush due to the different resistance force, and thereby effectively and uniformly brushing the teeth even when a user horizontally brushes his teeth along the sets of teeth.
- In order to accomplish the above object, the present invention provides a rotary toothbrush, comprising a longitudinal body including a head, at least one rotary bristle bed set on the head of the body through a shaft such that the bristle bed is rotatable relative to the head around the shaft, and a plurality of bristles implanted in the bristle bed such that the bristles generate different resistance forces against teeth in accordance with positions of the bristles on the teeth during a tooth brushing process. Due to the different resistance forces, the rotary bristle bed is rotatable in either direction around its shaft on the head of the body.
- When brushing teeth using the toothbrush of this invention, a user horizontally and repeatedly bushes his teeth along the sets of teeth, with the bristles of the rotary bristle bed brought into contact with the outer surfaces of the teeth. In such a case, the bristles form desired different resistance forces against the teeth, and actively and smoothly rotate the bristle bed in either direction due to the different resistance forces. The bristles are thus rotated in the same direction as that of the bristle bed, and so it is possible to effectively brush the teeth. In addition, this rotary toothbrush accomplishes its desired operational effect by the movement of the bristles relative to the teeth, and so it does not require any electric drive means or another complex structure, and has a simple construction capable of reducing the production cost of the toothbrushes.
- The above and other objects, features and other advantages of the present invention will be more clearly understood from the following detailed description taken in conjunction with the accompanying drawings, in which:
- FIG. 1a is a plan view of a rotary toothbrush in accordance with the preferred embodiment of the present invention, FIG. 1b is a front view of the rotary toothbrush of this invention, and FIG. 1c is a bottom view of the rotary toothbrush of this invention;
- FIG. 2 is a sectional view of the toothbrush's head having two rotary bristle beds in accordance with the present invention; and
- FIG. 3 is a plan view of the two rotary bristle beds of this invention, each having different groups of bristles.
- Reference now should be made to the drawings, in which the same reference numerals are used throughout the different drawings to designate the same or similar components.
- FIGS. 1a to 1 c are views, showing the appearance of a rotary toothbrush in accordance with the preferred embodiment of the present invention, in which FIG. 1a is a plan view of the toothbrush, FIG. 1b is a front view of the toothbrush, and FIG. 1c is a bottom view of the toothbrush.
- As shown in the drawings, the toothbrush according to the preferred embodiment of this invention comprises a longitudinal body, and two
rotary bristle beds handle 1, aneck 2 and ahead 3, while the two rotary bristle beds 4 and 5 are set on thehead 3 of the body such that thebeds head 3. A plurality ofbristles 8 are densely implanted on each of thebeds head 3 to perform its desired operational effect without affecting the functioning of this invention. - In the preferred embodiment of this invention, the two
rotary bristle beds head 3 so as to be spaced apart from each other while forming a predetermined gap between them. Each of the twobristle beds shaft bristle beds head 3, twoshaft holes head 3 at desired positions. The twobristle beds head 3 by removably and rotatably fitting theshafts shaft holes head 10 and holding theshafts head 3 usingwashers beds head 3. - In such a case, the two
rotary bristle beds head 3 of the toothbrush such that thebristles 8 of the twobristle beds bristles 8 on the teeth when a user horizontally brushes his teeth along the sets of teeth. Therotary bristle beds shafts head 3 in either direction due to the different resistance forces. - FIG. 2 is a sectional view of the
head 3 having the tworotary bristle beds bristle beds bristles 8. As shown in the drawings, the twobristle beds rear bed 5, positioned at the rear end of thehead 3, to be larger in its diameter by about 1.10˜1.15 times than that of thefront bed 4 positioned at the front end of thehead 3. In addition, it is preferred to design the top surface of each of the twobeds beds bristle beds head 3 such that theirrotating shafts beds head 3 such that therotating shafts beds beds head 3 such that the front portion of thehead 3 for holding thefront bed 4 is inclined relative to the rear portion holding therear bed 5 at an inclination angle of 5°. In such a case, it is necessary to space the twobeds - In the present invention, the
bristles 8, implanted on each of the twobeds front bed 4 has two different groups ofbristles rear bed 5 has three different groups ofbristles - In a detailed description, the bristles included in the
first bristle group 8 c of therear bed 5 are the same in their thickness, strength and length as those of the bristles included in thesecond bristle group 8 d, but are different in their implanting density from that of the bristles of thesecond bristle group 8 d. Therefore, the resistance forces formed between the bristles of thefirst bristle group 8 c and the teeth are different from those of the bristles of thesecond bristle group 8 d during a tooth brushing process, and so it is possible to rotate the rear bristlebed 5 on thehead 3 due to a difference in the resistance force between the two bristlegroups - In addition, the
bristles 8 d-1 included in thesecond bristle group 8 d of therear bed 5 are the same in their thickness, strength and length as those of thethird bristle group 8 e, but are different in their heights above the top surface of thebed 5 from those of the bristles of thethird bristle group 8 e. In such a case, desired different resistance forces are formed between thebristles 8 of the rear bed S and teeth during a tooth brushing process, and so the bed S is rotated on thehead 3 in either direction due to the different resistance forces. - On the other hand, the bristles included in the
bristle group 8 a of thefront bed 4 have different in their strength from the bristles included in theother bristle group 8 b. Due to the difference in the strength between the bristles of the twogroups bristle group 8 a is different from that of thebristle group 8 b, and so thefront bed 4 is rotated on thehead 3 in either direction due to the difference in the resistance force between the two bristlegroups - The arrangement of the
bristle groups beds - When brushing teeth using the toothbrush of this invention, a user horizontally and repeatedly bushes his teeth along the sets of teeth, with the
bristles 8 of the two rotary bristlebeds bristle groups beds shafts bristles 8 of the twobeds shafts beds - As described above, the present invention provides a rotary toothbrush. In the rotary toothbrush, the bristles move on teeth while generating different resistance forces against the teeth in accordance with positions of the bristles on the teeth, thus forcing the rotary bristle beds to be automatically rotated on the head of the toothbrush due to the different resistance forces. Therefore, this toothbrush effectively, uniformly and quickly brushes the teeth without difficulty even when a user horizontally brushes his teeth along the sets of teeth. The rotary toothbrush of this invention accomplishes its desired operational effect without requiring any electric drive means or another complex structure, and so the toothbrush has a simple construction and is produced at a low production cost.
