Abstract

A brush comprising a housing having an opening at which there is a pad and bristles. The housing defines an interior space and a handle. In the interior space, there is located a fluid reservoir, a pump assembly having a pump cylinder tube and plunger, and a piping array which are airtight and fluidly connected to one another. In a preferred embodiment, a plurality of silicone, duckbill ejection valves are provided at the ends of the piping array and are positioned on the pad among the bristles. To enable movement of fluid from the reservoir to and out of the ejection valves, an actuator lever is provided and adapted to be operated by a user. The actuator lever is adapted to move between a first position and a second position, creating a pumping action to dispense fluid through the ejection valves.

Claims

1. A brush, comprising:

a first casing having a first opening;

a second casing engaged to said first casing and together defining an interior space and a handle;

a pad positioned at said first opening of said first casing;

a plurality of bristles located at said pad;

a fluid reservoir positioned in said interior space;

a pump assembly positioned in said interior space and fluidly connected at a distal end thereof to said fluid reservoir;

a piping array positioned in said interior space and fluidly connected to said pump assembly;

a plurality of ejection valves fluidly connected to said piping array and positioned on said pad among said plurality of bristles;

an actuator lever adapted to be operated by a user and moved between a first position and a second position, said actuator lever connected to said pump assembly to move and dispense fluid through said plurality of ejection valves; and

wherein, when said actuator lever is moved from said first position to said second position, fluid in said fluid reservoir is suctioned from said fluid reservoir.

2. The brush of claim 1, wherein said fluid reservoir, pump assembly, piping array and plurality of ejection valves are in airtight connection with one another to hinder fluid therein from evaporating or drying.

3. The brush of claim 2, said pump assembly comprising a pump cylinder tube having a first end, a second end and a hollow member, a valve disposed interior of said pump tube and a pump tube cylinder cover.

4. The brush of claim 3, said pump assembly further comprising a plunger disposed within said pump cylinder tube and a plunger cover.

5. The brush of claim 4, wherein said plunger is configured to move within the said pump cylinder tube when the actuator lever moves to said first position and said second position.

6. The brush of claim 5, wherein said plunger cover comprises a pair of bosses, wherein said actuator lever is attached to said plunger cover via said bosses to move said plunger within said pump cylinder tube.

7. The brush of claim 6, wherein said pump assembly is held in place in a molding in said second casing.

8. The brush of claim 1, further comprising a pressure cap in said fluid reservoir, wherein when said fluid is pumped from said fluid reservoir, said pressure cap moves toward said piping array.

9. The brush of claim 1, wherein each of said plurality of bristles have a shaft with a polygonal cross-section.

10. The brush of claim 9, wherein each of said plurality of bristles have a hexagonal pyramid tip.

11. A brush, comprising:

a housing, having a first section and a second section, said housing defining an interior space and a handle area at said first section;

an airtight fluid dispensing mechanism disposed within said interior space of said housing, said airtight fluid dispensing mechanism comprising a fluid reservoir, a pump assembly, a feeder tube, and a plurality of ejection valves;

an actuator, said actuator being connected to said pump assembly and adapted to pump fluid from said fluid reservoir to said ejection valve via said feeder tube;

a plurality of bristles disposed at said second section of said housing, said bristles having a shaft with a polygonal cross section;

wherein said fluid reservoir is disposed in said interior space at said handle area of said housing; and

wherein said fluid reservoir, said pump assembly, said feeder tube, and said plurality of ejection valves are in airtight fluid connection with one another to enable movement and dispensing of fluid from said fluid reservoir to said plurality of ejection valves.

12. The brush of claim 11, wherein said plurality of ejection valves each comprise an airtight, one-way, duckbill valve.

13. The brush of claim 11, wherein said feeder tube comprises an inlet and a plurality of outlets, wherein each outlet leads to one of said plurality of ejection valves.

14. The brush of claim 11, wherein said pump assembly comprises a pump cylinder tube, a flange tube and a plunger.

15. The brush of claim 11, wherein said fluid dispensing mechanism further comprises a flange tube disposed between said feeder tube and said pump assembly.

16. The brush of claim 15, wherein said flange tube and said pump cylinder tube are held stationary in said housing, and said plunger is adapted to within said pump cylinder tube to move fluid from said fluid reservoir to said feeder tube.

17. A brush, comprising:

a housing having a first opening, second opening and third opening and defining a first interior chamber, a second interior chamber and a handle;

a pad positioned at said first opening;

a plurality of polygonal-sided bristles located at said pad;

a fluid reservoir positioned in said first interior chamber;

a cover to maintain said fluid reservoir in said first interior chamber;

a pump assembly positioned in said second interior chamber and fluidly connected at a distal end thereof to said fluid reservoir;

a piping array having an inlet, a plurality of outlets and a main distribution line, said piping array positioned in said second interior chamber and fluidly connected to said pump assembly via said inlet;

a plurality of ejection valves fluidly connected to said piping array via said plurality of outlets and positioned on said pad;

an actuator lever adapted to be operated by a user and moved between a first position and a second position, said actuator lever connected to said pump assembly to move and dispense fluid through said plurality of ejection valves; and

wherein, when said actuator lever is moved from said first position to said second position, fluid in said fluid reservoir is suctioned from said fluid reservoir.

18. The brush of claim 17, wherein said piping array comprises five asymmetrically positioned pipes that each lead to one of said plurality of ejection valves.

19. The brush of claim 17, wherein each of said plurality of ejection valves is formed of silicone.

20. The brush of claim 17, wherein fluid from said fluid reservoir moves along a common axis when it travels from said fluid reservoir, to said pump cylinder tube, and to said main distribution line.
