Abstract
A toothbrush for cleaning teeth includes a body defining an internal fluid reservoir, a plurality of bristles supported at a base portion by the body, a passage extending from the internal fluid reservoir to at least one opening adjacent the base portion of the plurality of bristles, and a manually operated pump disposed in fluid flow communication between the internal fluid reservoir and the passage for transferring fluid from the internal fluid reservoir to the at least one opening in the base portion between the bristles.
Description
- This application claims priority to the benefit of the Sep. 22, 2009, in the name of Diane Richardson, filing date of co-pending U.S. Provisional Patent Application Ser. No. 61/244,478 filed Sep. 22, 2009, for a “WATER GUN TOOTHBRUSH”, the entire contents of which are incorporated herein by reference.
- The present water pump toothbrush relates in general to toothbrushes and, more particularly, to a toothbrush having a pump for transferring fluid from the internal fluid reservoir to a position adjacent a base portion of a plurality of bristles supported by a body of the toothbrush.
- Various configurations for toothbrushes are well known in the art. While these devices appear to be suitable for the intended purpose of cleaning teeth, the known toothbrushes suffer from various deficiencies and lack desired features. By way of example and not limitation, known toothbrush devices fail to provide a readily available source of fluid, such as liquid water, for aiding in the cleaning and/or rinsing process.
- A water pump toothbrush according to one aspect of the present invention is a manual toothbrush used along with conventional toothpaste. During use, toothpaste is spread on the toothbrush bristles as is conventional. The water pump toothbrush provides the advantage of a readily available source of fluid, such as liquid water, for aiding in the cleaning process by squirting fluid, such as liquid water, on the bristles when the user is ready to begin brushing their teeth. The water pump toothbrush can operate similar to a toy water gun. The fluid, such as liquid water, can squirt out when a button located on a body of the toothbrush is pushed by the user.
- A majority of people run water to wet a toothbrush in preparation to begin brushing their teeth, because the combination of water and toothpaste is more efficient working together to clean the teeth.
- The water pump toothbrush has many advantages. By way of example and not limitation, the water pump toothbrush eliminates the common habit of continually running water from the faucet and thereby wasting a valuable natural resource. No more hand movement required back and forth to the running faucet to wet the toothbrush in preparation to begin or to continue brushing teeth. The water pump toothbrush keeps the user brushing at a steady pace. The fluid stored inside an internal reservoir defined by the body of the toothbrush is ready to use at the push of a button, which makes the water pump toothbrush convenient and easy to use. The water pump toothbrush is also a convenient way to brush teeth when a source of running water is unavailable. The water gun toothbrush simplifies the task of brushing young children's teeth, and can make brushing more fun for children as they grow older.
- With the water pump toothbrush, a user can now brush with any desired fluid, by way of example and not limitation, liquid water, mouth wash, plaque rinse, and other mouth cleaning liquids.
- The description herein makes reference to the accompanying drawing wherein like reference numerals refer to like parts throughout the several views, and wherein:
-
FIG. 1 is a simplified perspective view of one aspect of a water pump toothbrush; and -
FIG. 2 is a longitudinal cross-sectional view of the water pump toothbrush shown inFIG. 1 . - Referring now to
FIGS. 1 and 2 , awater pump toothbrush 10 is illustrated. Thetoothbrush 10 for cleaning teeth includes abody 12 defining aninternal fluid reservoir 14. Thefluid reservoir 14 may comprise substantially all of the interior of thebody 12 or only a portion of thebody 12, such as the portion extending from the end of theneck 22 to the end of thebody 12 which receives thecap 30. A plurality ofbristles 16 are supported at abase portion 18 by ahead 20 of thebody 12. Thehead 20 can be supported from aneck portion 22 of thebody 12. Theneck portion 22 can be integrally with thebody 12 or as adiscrete neck portion 22 which is removably attachable to thebody 12. Anouter end portion 24 of the plurality ofbristles 16 contact the teeth for cleaning. Afluid flow passage 26 extends from theinternal fluid reservoir 14 to a position adjacent thebase portion 18 of the plurality ofbristles 16. Apump 28 is located in thepassage 26 for transferring fluid from theinternal fluid reservoir 14 to thebase portion 18 of thebristles 16. - The
body 12 of thetoothbrush 10 can be any size and shape desired. Preferably, thebody 12 is of a sufficiently small size and shape to be grasped within the palm of one hand during use. It should be recognized that alarger body 12 can accommodate alarger fluid reservoir 14. Thefluid reservoir 14 includes a removable cap orplug 30 allowing thefluid reservoir 14 to be filled or refilled by a user. The cap orplug 30 can be threaded or friction fit to one end of thebody 12 to seal and prevent leakage from thereservoir 14. A one way vent valve, not shown, can be provided in thecap 30 or in thebody 12 to prevent any build up of vacuum pressure within thereservoir 14 during dispensing of fluid by thepump 28. - The
bristles 16 can be provided with uniform size, length, and shape, or can be provided with differing size, length and/or shape if desired. Thepassage 26 through theneck portion 22 includes at least one opening orport 34, preferably adjacent thebase portion 18 of thebristles 16, for dispensing fluid from thereservoir 14. The port orports 34 are interspersed with the bottom ends of thebristles 14 on thebase portion 18. The port orports 34 can have any suitable diameter, such as onelarge diameter port 34, or a plurality ofsmaller diameter ports 34, or a combination ofdifference diameter ports 34. Thepassage 26 can also includecheck valves passage 26 and on the discharge portion of thepassage 26 to prevent backflow of fluid. - The
pump 28 can be either manual or electric. By way of example and not limitation, thepump 28 inFIGS. 1 and 2 includes apiston 44 reciprocally supported in ahollow member 46 fixed in thebody 12 to define apumping chamber 48. - The
hollow member 46 is coupled in fluid communication with thepassage 26. Thepumping chamber 48 has asuction portion 40, which communicates with an inlet to themember 46 and thefirst check valve 36, and adischarge portion 42 which communicates with an outlet in themember 46, thesecond check valve 38 and thepassage 38. Thepiston 44 is biased byspring 50 toward a first position, where the pumping chamber is enlarged to a first volume in thechamber 46. - A
flexible tube 49 is coupled to the inlet of themember 46 to collect water from the bottom of thereservoir 14 during use of thetoothbrush 10. - During use, the “trigger” 52 is pressed by the user to urge the
piston 44 against the biasing ofspring 50 toward a second position of reduced volume in thechamber 48. Thefirst check valve 36 prevents backflow of fluid through thesuction portion 40 of thepassage 26 toward thereservoir 14. Fluid discharged by thepiston 44 movement is directed through thedischarge portion 42second check valve 38 to thepassage 26 to be dispensed out ofport 34 at thebase portion 18 of thebristles 16. Release of thetrigger 52 by the user, draws fluid through thefirst check valve 36 from thereservoir 14 into thesuction portion 40 of thechamber 48 to prime thepumping chamber 48 by filling thepumping chamber 48 with water from the reservoir 1. Backflow of fluid through thepassage 26 and thedischarge portion 42 is prevented bysecond check valve 38. It should be recognized thatpump 28 can be any desired configuration, such as a manually operated piston pump, a manually operated diaphragm or bladder pump, or a battery operated rotary, piston, or diaphragm pump.
