Abstract
A handheld portable oral cleaning device that includes a refillable internal bladder, which a user is able to fill with a liquid. The bladder is preferably an expandable but resilient latex rubber. One end of the bladder is accessible to the user, such that the user may fill the bladder with a liquid, such as water from a faucet. As the bladder fills with water it expands and exerts a pressure on the water as the bladder has a tendency to return to its original unfilled form. The pressurized water may then be sprayed out of the oral cleaning device to assist in cleaning the user's mouth.
Claims12
An oral cleaning device comprising:
- a bladder contained within a body, the bladder is expandable to hold fluid and resilient to exert a pressure on fluid contained therein;
- a bottom portion attached to the body and having a one-way valve assembly attached to one end of the bladder, the one-way valve assembly in communication with an aperture defined on the bottom portion that allows fluid to enter the bladder;
- a neck and head assembly attached to the body, the neck and head assembly includes an aperture in fluid communication with another end of the bladder and is configured for expelling fluid and includes bristles for cleaning a portion of a user's mouth;
- and
- a mechanism disposed between the neck and head assembly and the bladder for controlling the flow of fluid from the bladder to the aperture.
An oral cleaning device having a body, and a head having an aperture, the oral cleaning device further comprising:
- a latex bladder positioned within the body and in fluid communication with a controlled release to release fluid within the bladder to the aperture, the bladder is further in fluid communication with a controlled opening to allow the flow of fluid from an outside source into the bladder, the bladder is expandable to allow a fluid to fill therein through the controlled opening and is resilient to exert a pressure on the fluid contained therein such that the fluid expels out of the bladder and out of the aperture when released by said controlled release;
- and
- where the head includes a nozzle positioned in the aperture of the head and sized for cleaning a portion of a user's mouth, and the head includes bristles positioned about the nozzle, the head further having a predetermined shape defined for a tongue brush, or a tooth brush.
An oral cleaning device comprising:
- a bladder to hold a liquid, the bladder is expandable and resilient such that the bladder tends to return to an unfilled position, the bladder being secured within a body which a user may grasp;
- a bottom portion having a one-way valve assembly secured to a first end of the bladder and the one-way valve assembly having an aperture sized to fit a faucet nozzle, such that when positioned over a faucet nozzle and the faucet is turned on, water will enter the bladder via the one-way valve assembly;
- a neck and head assembly attached to the body, the neck and head assembly includes an aperture in fluid communication with a second end of the bladder and is configured with a nozzle in fluid communication with a channel for jetting water out of the device and for cleaning a portion of a user's mouth, and wherein the neck and head assembly is defined to clean a first portion of the user's mouth and is interchangeable with a second neck and head assembly defined to clean a second portion of the user's mouth;
- and
- a fluid control mechanism attached between the second end of the bladder and the neck and head assembly, the control mechanism includes a valve that prevents water contained in the bladder from entering the channel and includes a release button that when pressed opens the valve to permit water contained in the bladder to enter the channel,
- whereby when the bladder contains water, the bladder having a tendency to return to unfilled positioned exerts a pressure on the water, such that the water is expelled out of the bladder and out through the nozzle in the neck and head assembly when the release button is pressed.
