Description
- This application is related to and claims the benefit of U.S. Provisional Patent Application Ser. No. 60/725,503 entitled “TOOTHBRUSH WITH INTEGRATED FAN” and filed on Oct. 22, 2005 for Ashok V. Joshi, which is incorporated herein by reference.
- The present invention relates generally to oral care devices, and more particularly to toothbrushes adapted to provide a flow of air through the brush head upon actuation by the user.
- Toothbrushes have been used as a hygienic aid in a variety of cultures for many years. Increasingly, toothbrushes have been used with a variety of compositions such as dentifrices (compositions which aid in cleaning teeth) and other substances which act to improve the smell of a user's breath, remove, dislodge, or kill bacteria, or otherwise improve oral health. As their popularity has increased, so has the industry behind the production and sales of toothbrushes and associated cleaning compositions.
- It has been discovered that providing oxygen to toothbrushes, and thus, to the oral cavity during brushing helps to break up clumps of bacteria, thus facilitating their removal from the surfaces of teeth and gums. Delivery of extra oxygen to the oral cavity may also hinder the development of anaerobic bacteria that are often responsible for unpleasant odors in breath. Some difficulty is faced, however, in providing oxygen to the oral cavity in a safe and convenient manner.
- Additional difficulty is faced in the industry in devising methods and means for administering a wide variety of beneficial agents to the teeth and/or mouth. Some such agents may be successfully delivered in dentifrice compositions, but others, due to their chemical properties may be unsuited for delivery in this manner. Others are useful only in such small quantities that delivery is highly difficult.
- Thus, it would be an improvement in the art to provide a toothbrush device that provides a flow of air, including oxygen, to the mouth during brushing. It would further be beneficial to provide a toothbrush containing its own onboard supply of a beneficial agent that can be vaporized and delivered from the toothbrush.
- Such a device and methods of its use are provided herein.
- The present invention has been developed in response to the present state of the art, and in particular, in response to the problems and needs in the art that have not yet been fully solved by currently available toothbrushes. Accordingly, the present invention has been developed to provide a toothbrush with an integral forced air apparatus that overcome many or all of the above-discussed shortcomings in the art.
- The toothbrush may, in the described embodiments, include a housing connected with a head portion. The housing may comprise an integral air apparatus configured to force air through a channel extending from the housing into the head portion. The head portion includes at least one gas emitter orifice through which air may pass and a plurality bristles extending outward from the head portion.
- In one embodiment, the toothbrush also includes a heating apparatus configured to raise the temperature of air being forced through the channel. Furthermore, the toothbrush may comprise a reservoir configured to maintain a beneficial agent that capable of being vaporized and carried with the flow of forced air through the channel. Examples of suitable beneficial agents include, but are not limited to, oxidizing agents, whitening agents, therapeutic agents, breath freshening agents, gingivitis-treating compositions, pain-relieving agents, and anti-inflammatory agents.
- In a further embodiment, the toothbrush may include an ozonator configured to introduce ozone into the flow of forced air. Additionally, in one embodiment, the integral air apparatus comprises a fan and motor assembly. Furthermore, the housing further comprises at least one louver configured to allow air into the housing, and the louver may be configured to block water from entering the housing.
- Other advantages and aspects of the present invention will become apparent upon reading the following description of the drawings and detailed description of the invention. These and other features and advantages of the present invention will become more fully apparent from the following figures and description, or may be learned by the practice of the invention as set forth hereinafter.
