20100282274 | DIRECT DRIVE ELECTRIC TOOTHBRUSH - An electric toothbrush has an axially elongated body having a handle defining a hollow interior region for holding a motor disposed therein, a head comprising a static bristle holder plate having tufts of bristles disposed thereon and an oscillatory head bristle holder with other tufts of bristles disposed thereon. One end of the drive shaft is connected to the motor and an opposite end to a cam for directly driving the cam which has at least one lobe a portion of which cam is received in an oscillatory cavity for imparting a pushing force on the walls of the oscillatory cavity in response to rotation of the drive shaft for moving the oscillatory head bristle holder with a back and forth oscillatory motion. By eliminating the need for precision gearing, this direct drive arrangement simplifies and makes more efficient the translation of rotary motion into oscillatory motion. | 11-11-2010 |
20120137454 | TOOTHBRUSH - A toothbrush provides a head with bristles, a neck and a handle. An eccentrically rotational weight is engaged for rotation with a motor. The motor and weight are disposed within the handle. The handle, neck and head each have a different intensity of vibration. The toothbrush houses an electrical circuit, which includes a processor and at least two LEDs (light emitting diodes) at least one of which illuminates the neck and optionally also the head and the ends of the bristles attached to the head. At least two of the LEDs in the circuit are capable of emitting different colored light with respect to each other. The at least two LEDs are switched on for a predetermined time in a predetermined sequence under the control of the processor. | 06-07-2012 |
20130041329 | NASAL RINSING DEVICE - The present invention is directed towards a nasal rinsing device also known as a neti pot. The neti pot comprises a container body for holding liquid, a removable cap, and an extended pouring spout that directs a saline solution into nasal passages. The cap provides an adequate liquid-seal and venting for airflow into the interior of the pot. | 02-14-2013 |
20130180062 | SKIN SENSING ACTIVATED DEVICE - An electrical device such as an electric toothbrush that comprises a handle and a head portion. The head portion comprises a bristle bearing portion and an optional neck portion. The handle includes a housing having a housing exterior. First and second conductive contacts are located on the exterior of the housing. The first and second conductive contacts form part of a high impedance touch sensitive circuit configured to operate a motor to drive the bristle bearing portion when the handle is gripped by a user. | 07-18-2013 |
20140259486 | PLASTIC BRISTLES INFUSED WITH CARBONATE - Polymers are infused with carbonates, such as alkali metal or alkaline earth metal salts of carbonate, bicarbonate and sesquicarbonate, alone or in combination. The carbonates are soluble, soft, and have been infused within the polymeric material in a sufficient amount to provide an alkaline aqueous environment to inhibit microbes when the polymeric material is contacted with water. | 09-18-2014 |
