Description

CLEANSING DEVICE

BACKGROUND

Field of the Invention:

This application concerns a cleansing device. In particular, the toothbrush is equipped to provide sonic vibrations and negative ions during brushing.

Description of R elated Art:

The surface of a tooth has a negative electrical charge, and plaque has a positive charge. Opposite ions attract, so the plaque adheres to the teeth. When generating ions, the surface of the teeth is temporarily turned into a positive charge, so that loosening and repelling occurs, Also, the electrical circuit causes the bristles of the toothbrush to carry a negative electrical charge, which attracts the positive charge of the plaque.

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 (he skin in one's mouth to improve cellular activity. With rapid development of technology, toothbrushes having embedded electronic devices can be generally ibund 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.

Manual toothbrushes are the most basic in design, and are generally characterized by a single-piece handle design and brush head or refill. The consumer's expectation of this segment is thai most of the work of brushing will be done by the brush er. Some features that differentiate manual toothbrushes from each other are brush head size (often expressed in number of tufts: i.e., 35, 40, 60), bristle stiffness, bristle pattern, bristle color or concentration (power tip), indicator bristles that fade away io show loss of cleaning effectiveness over lime, handle materials (soft, eiasionseric, clear) or design (decoration, color, shape or ergonomics).

BRIEF DESCRIPTION OF THE DRAWINGS FIG, I is an exploded view of a embodiment of the present invention.

FIG. 2 is a perspective view of an embodiment of the present invention as assembled.

DETAILED DESCRIPTION

Referring to FIG, 1 and FIG, 2, is a cleansing device 100 of the present invention includes a handle portion 12 and a bristle brush end portion 15, A metal strip 50 can act as an anode and be positioned through an opening 80 in the handle 12 of the sonic-ionic toothbrush that touches a user hand when the toothbrush is being used. The user's hand can be wet or does not need to be wet because the skin (hand) is naturally moist (resistance). A metal cathode S 1 is located adjacent, the bristles ί i of the toothbrush. An electrical circuit 20 powered by one or more batteries 40 internal to the handle provides electrical potential to the anode. The battery or batteries can be housed in a holder 30 When the toothbrush is in use and the user is touching the metal strip 50 a electrical circuit is completed such that the electrical potential from the battery 40 at the cathode S I causes ions to flow from the cathode to the metal strip 50 thereby causing the emitted ions to be imparted to the surface of the user's teeth.

Body's energy (hand) starts the circuitry as a conductor, but also the body plays an Important role in the overa.il ionic function as the flow of negative ions from toothbrush head bristle brush from the cathode (ion emitter) througii the teeth and gums and back into the user's body or hand on the metal strip SO to complete the electrical loop.

The bristle brash end portion 1 with toothbrush bristles 1 1 are movable with respect to the toothbrush handle ! 2. A vibrating device 90 can cause the bristles 1 i to vibrate with respect to the handle 12. Such vibrating devices are well-known to those of ordinary skill The bristle end 15 of the toothbrush may be removable md replaceable as i known in the art. Sonic or vibrating function usually provides 20.000 to 30.000 strokes or vibrations per minute. The most common mass market sonic toothbrushes are 20/000 strokes per minute, An ultrasonic toothbrush function can be added and combined with ionic function or the user can use solely ultrasonic function,

A mode switch 95 on the toothbrush handle is provided so the bristles 1 1 can be selected by the user to concurrently or alternatively vibrate with the emitting of ions, Ionic function can loosen and repel plaque and bacteria through polarization technology. Sonic function (sonic vibration) will move around plaque and bacteria, but may not loosen and repel it as the ionic function will (through polarization technology). Also, the ionic function at 9 V to 12 V power (which are safe power levels for the human body) loosens and repels plaque faster. The new combination of ionic and sonic in one toothbrush should provide the best results and performance for users. A light 5 U which may be mounted on handle 12 through an opening 52 can be used to indicate when the ionic function is active.

A second switch 200 can have .multiple settings to alter the number of vibrations per minute. A second light or lights 210, which may be mounted on handle 12 can be used to indicate which of the. multiple settings the mode switch is in.

One battery 40, for example a AAA battery, can be used to power the electrical circuit 20. The battery can be located within the handle and be replaceabie. Voltage booster circuitry (not shown) within the handle can boost 1.5 V up to about between 9 V to 12 V or any voltage necessary to activate the vibration device and provided ion flow. Alternatively, there can be multiple single cell batteries to power the toothbrush.

The voltage booster circuit can generates 9 to 12 volts from a i .5 volt AAA battery, which generates more negative ions (6x to 8x) and power during 1.5 to 2 minutes of brushing. This elevated voltage can provide better results for less plaque accumulation and less inflammation of the gums than at a lower voltage. The sonic-ionic toothbrush combines sonic vibration and 9 to 12 volts of ionic polarization power. It. can do the work of 6 to8 batteries in a small amount of time and in a small amount of space. Thus, the single cell 1.5 volt battery (coupled with the booster circuit) powers both sonic and ionic functions.

The user does not need to operate both ionic and sonic functions at same time. The user can use solely ionic function or solely sonic function, or both sonic and ionic together. The mode switch 95 as discussed above is provided for this purpose, Alternatively, ionic function can operate using 1.5 V or 3 V and does not need to have booster circuit for the ionic function, Although 9 V or 12 V is preferable to improve the ionic function and yield better results for loosening and repelling plaque and bacteria from the teeth and mouth.

A light 60 can turn on to show thai ions are flowing and output is 9 V or 12 V (or an output that is required between 1 ,5 V and 12 V). This light can work at the same time sonic function is powered on or when user is solely using ionic function and sonic function is powered off. The light will glow to show the ionic function works when the user is holding the toothbrush and brushing their teeth. The user's body's energy starts the circuitry, in an implementation, the light 60 can include a light emitting device 21 electrically connected to the electronic circuit 20, and a light guide post 61 mounted to the handle located adjacent the light emitting device 21. The light guide post has a portion extending to the exterior the handle so as to transmit-light from light emitting device. Thai is, the light source is visible through the light guide post and the light guiding and refracting material, in an implementation, light emitted by the light emitting device 2 is visible as shown in FIG 2 on the same side of the handle as the bristles 1 1. in another implementation, the light emitted from the light emitting device 21 is visible on the opposite side of the handle on which the bristles are located. That is, the light is sot directly visible to the user when the toothbrush bristles axe facing the user, as in when the user is brushing their teeth. Rather the light may be visible by reflection in a mirror in front of the user.

Bristles of the toothbrush are typically soft and made of Nylon or other synthetic materials. While soft bristles are recommend, any medium or hard toothbrush bristles can be used. The ionic function and power loosens plaque easily, so users do not need to brush hard. However, users can brush at any level they wish. The sonic or ultrasonic toothbrush function can have an ON/OFF switch 200. This svyitch may have multiple settirigs to offer options for speed and power. This switch may have a power light to indicate the ON position and a light or iights to indicate which of the multiple settings the device is in.

in use the present toothbrush can be a single-use device or have a replaceable bristle head with soft polypropylene handle and nylon bristles. Despite its advanced function and benefits, the toothbrush can look and feel, much like an ordinary toothbrush. The handle can be fully sealed to keep out water or substantially watertight and have a replaceable battery. The light, can be a light-emitting diode (LED) or other lamp to indicate when the user has completed the electrical connection and the ionic action is functioning.

The user simply touches a finger or hand, preferably wet, to the metal anode o the handle while brushing to engage the ionic action and see the light on the handle illuminate. The brush head can be any size and the bristles are soft with a staggered brush trim thai emphasizes the soft feet of the bristles in the mouth. The bristle pattern is designed to toothpaste well . Both a large brush head size and the ability to hold toothpaste are attributes appreciated by some users.

The sonic-ionic toothbrush will allow users to have an interactive brushing experience. Users can brush with ionic polarization for 1 minute to loosen plaque at 9 volts and top it off with sonic vibration for 1 minute to finish off with sonic power and hit the gum lines and hard to reach areas. Or users can brush with both sonic and ionic together, or sonic only. Users can make their own brushing plan for what they feel is best suited for their teeth and how they feel or want to feel. W

The sonic-ionic toothbrush technology can provide relief from painful dental sensitivity. It is hypothesized thai the ionic action of the toothbrush facilitates the deposit of fluoride onto the teeth, which is often used in the treatment of tooth sensitivity.

Other embodiments are within the scope of the following claims.
