Water pressure driven tooth brush (hydratoothbrush) with dental jet
First Claim
1. Looking for the protection of the United States Patent Office for the said following claims. The ornamental designed herein called HydraToothbrush is designed for new and economical way to automate the tooth brushing with a built in Dental jet as it described and shown in the drawing pages. The HydraToothbrush has a special removable, interchangeable head assembly used for brushing the teeth and Water jet section to flush out food derbies left behind by the brushing. Diverter has dual functions, selecting the water to the impeller or to the Dental Jet. In fully diverted position the water flow is the maximum, and in partial diverted position brush rotation becomes slower. In the DentalJet position pressure and water flow also reduced in partial divertion. On page 1 the HydraToothbrush uses the water pressure driven impeller to rotate the shaft which connects to a cone gear to rotate the tooth brush. Rotating shaft driven Detachable Brush/Jet head. 2 On page 2 the rotating shaft is spring loaded, connects to the disk driver which oscillates the brush, the rotating motion is converted to an oscillating brush movement. On page 3 FIG. 8 shows a water pressure activated coupling to the Dental Jet with and expandable bulb. As the water is diverted to the detachable brush/jet assembly the expandable bulb slides inside the small tube connecting to the jet'"'"'s nozzle. The diameter of the incoming water line is larger than the diameter after the bulb. The water pressure will expand the bulb, keeping it tight. On page 4 FIG. 10 shows a Longitudinal impeller built into the Brush head/Dental jet assembly. This is a dual Hydrabrush/Dental jet assembly connects to the handle with threaded coupling. Water connections are sealed with O rings. The Hydrabrush/HydraJet assembly is detachable, interchangeable for the user.

Abstract
This oral cleansing device assembly is an oral hygiene tool, which connects to the water faucet, uses normal water pressure in the system. All electric toothbrushes use a small motor, rechargeable or alkaline battery operated.
High frequency vibrators, or piezo electric drive to rotate or oscillate the tooth brush head.
This invention uses no electricity, no battery, brush driving power is derived from the water system.
This combination, dual mode invention has two modes of operation, tooth brushing and dental jet.
The oral cleansing device assembly consists of a diverter at the end of the faucet connecting to the HydraToothBrush with a vinyl or similar plastic tube to activate it. The water comes into the built in diverter with adjustable flow and direction control, water flows trough the impeller, it rotates a detachable shaft in the brush/water jet assembly. In FIG. 1 page 1 and in FIG. 11 on page 4 shaft transfers the rotation trough cone gears to the tooth brush. In FIG. 4 page 2 the brush driving power derives from the rotating disk with bumps on it. As the water pressure driven disk rotates the brush driving shaft “rides” on the bumps and the brush will oscillate within 90 degrees. The shaft at the end is spring loaded, to return the shaft for the next lifting cycle. On page 3 FIG. 12 the rotating disk oscillates the brush in the head assembly. The built in diverter in the HyraToothBrush in the HydraJet mode diverts the water to the nozzle to clean any derbies from the oral cavities, from under the bridge works what the brush could not reach.
