Oral hygiene apparatuses using faucet water flow to produce spray jet

A oral hygiene apparatus for use with a faucet providing a flow of water and a oral hygiene substance, the apparatus comprising:

• valve means adapted to fit to the faucet to receive a flow of water therefrom, for selectively providing the water flow through a first faucet orifice and a second auxiliary orifice;
• container means for holding the oral hygiene substance;
• first coupling device means for releasably locking the valve means in communication with the container means so that the water flow travels from the valve means at its second orifice to the container means, the water mixing with the oral hygiene substance in the container means to produce a liquid mixture;
• hose means having first and second ends, for guiding the liquid mixture from the container means;
• second coupling device means for releasably locking the container means in communication with the hose means, the second coupling device means receiving a flow of the liquid mixture from the container means and supplying the liquid mixture flow to the first end of the hose means;
• and
• jet tip means coupled to the second end of the hose, the jet tip means for receiving the liquid mixture flow and for generating a spray jet with the liquid mixture flow for use in oral hygiene,
• wherein at least one of said first and second coupling device means comprises opposing spring-loaded levers operable to selectively couple respective passages of first and second elements in communication with one another, each said spring-loaded lever pivotally mounted to an outer surface of said coupling device means at a fulcrum positioned between a locking end and a releasing end of said lever, said lever mounted along a longitudinal direction of said coupling device means such that said locking end extends towards an outer surface of said coupling device means and is spring-biased to releasably lock into a groove on said first or second element.
