Abstract
Description
- The present application is a continuation of pending U.S. patent application Ser. No. 11/797,097, filed on Apr. 30, 2007, which claims priority from Taiwanese Patent Application No. 095220902, filed on Nov. 26, 2006. All prior applications are herein incorporated by reference.
- The present invention relates to a toothbrush, and more particularly, one provided with a power source, a light source, and an electronic circuit to release electric ions to automatically generate ions into an oral cavity to help maintain oral hygiene.
- Conventional toothbrushes generally available in the market usually have multiple rows of bristles disposed on an end of a handle for removing residuals found in gaps between teeth to maintain oral health when used in conjunction with toothpaste. However, they fail to reach deeper to the skin in one's mouth to improve cellular activity. With rapid development of technology, toothbrushes having embedded electronic devices can be generally found in the market. The electronic devices, including circuits and associated electronic parts are essentially soldered together. Therefore, the electronic device is limited in function and deprived of becoming more practical in use by consumers.
- The primary purpose of the present invention is to provide a toothbrush with a circuit that is capable of improving oral cavity health, displaying an innovative light performance, allowing easy operation and reducing production cost. To achieve these objectives, the toothbrush has an embedded power source connected to a circuit assembly provided with a light guide structure, and an ion generation device.

FIG. 1 is an exploded view of a first preferred embodiment of the present invention. -
FIG. 2 is a perspective view of the first preferred embodiment of the present invention as assembled. -
FIG. 3 is an exploded view of a second preferred embodiment of the present invention. -
FIG. 4 is an exploded view showing an electronic device of the second preferred embodiment of the present invention. -
FIG. 1 shows an exploded view of a first preferred embodiment of the present invention, in which acontrol circuit 20 is disposed in ahandle 12 of atoothbrush 10 having multiple rows ofbristles 11.Conductive plates Contacts conductive plates cell 40. Asignal electrode 34 extends from theconductive plate 31. Aconductive plate 50 is disposed on and slightly protrudes from thehandle 12 of thetoothbrush 10. Thesignal electrode 34 is connected to theconductive plate 50. - A light-
emitting device 21 is connected to thecontrol circuit 20. Aconductive block 51 is also connected to thecontrol circuit 20 and is disposed near the end of thetoothbrush 10 having thebristles 11. Alight guide post 60 is located in thetoothbrush 10 near to where the light-emitting device 21 is located. Thelight guide post 60 has a recessedlight guide edge 61 disposed immediately next to a front end of the light-emitting device 21 such that light from light-emitting device 21 is visible through an exposed end oflight guide post 60. Thecontrol circuit 20 of thetoothbrush 10 is sealed in thehandle 12 by acover 70. - Now referring to
FIG. 2 , for a sectional view showing the preferred embodiment as assembled, wherein theconductive plate 31 on thecontrol circuit 20 of thetoothbrush 10 is provided with thecontact 32 and thesignal electrode 34 is in contact with theconductive plate 50. This structure saves soldering of multiple lines, a job otherwise required in the prior art, to reduce production cost. Theconductive plate 50 and theconductive block 51 disposed in the handle of thetoothbrush 10 enable, when the toothbrush is held and dipped in water by a user, thecontrol circuit 20 to be automatically operated to generate ions near thebristles 11 for cleaning the oral cavity of the user and, at the same time, to automatically cause the light-emitting device 21 to illuminate. The light-emitting device 21 may be a monochromatic or a multi-color light source adjacent to thelight guide edge 61 of thelight guide post 60. One end or both ends of thelight guide post 60 are slightly exposed out of the toothbrush handler to enable light from the light-emitting device 21 to be visible externally of thetoothbrush 10 to prompt the user that thetoothbrush 10 is in use. If thetoothbrush 10 and/or thecover 70 is made of a material that is capable of refracting or guiding light, the toothbrush may provide unique light and shade performance effects when the light-emittingdevice 21 is activated to emit light. -
FIGS. 3 and 4 show a second preferred embodiment of the present invention, in which the same results can be achieved by having theconductive plate 50 disposed on thecover 70 beneath thecontrol circuit 20 and having theconductive plates - The present invention discloses a toothbrush including an electronic circuit disposed within a handle of the toothbrush and includes a combination of a power source connected to the circuit, a light guide structure and an ion generation device. The toothbrush achieves its purposes of maintaining oral hygiene, displaying innovative color performance effects, allowing easy operation, and reducing production cost to add more practical and economic values to the toothbrush.
