Abstract

Embodiments of the invention are directed to an outdoor paint sprayer having an air pump chamber separate from a refillable and/or replaceable paint chamber. In some aspects, the outdoor paint sprayer is configured to dispense a liquid paint with minimal dilution, such that a paint having an original concentration may be aspirated and dispersed by the outdoor paint sprayer without requiring additional manipulation of the paint outside of the sprayer. In some aspects, the outdoor paint sprayer includes one or more nozzle features and/or tips that produce a desired spraying application. In further aspects, additional features for emulating a particular marking effect may be incorporated with and/or coupled to the sprayer for application.

First claim

The invention claimed is:

1. An outdoor paint sprayer device comprising:
a nozzle assembly comprising a spray tip and a dispersion nozzle for dispersing an atomized paint from a liquid paint product, wherein the dispersion nozzle comprises a plurality of orifices;
a sprayer body coupled to the dispersion nozzle, at a first position of the sprayer body;
a paint chamber coupled to the sprayer body, at a second position of the sprayer body; and
an air pump chamber coupled to the sprayer body at a third position of the sprayer body;
wherein the sprayer body comprises a paint hose structure for providing the liquid paint product to the sprayer body, wherein the paint chamber provides the liquid paint product to the paint hose structure, wherein the dispersion nozzle receives the liquid paint product from the paint hose structure.

2. The device of claim 1 wherein the paint chamber is removably coupled to the sprayer body.

3. The device of claim 1 , wherein the paint chamber comprises:
a proximal first end of the paint chamber, wherein the proximal first end of the paint chamber is coupled to the sprayer body;
a distal second end of the paint chamber opposite the proximal first end; and
a one-way air valve wherein the one-way air valve is configured to transfer air flowing into the paint chamber.

4. The device of claim 3 , wherein the paint chamber further comprises:
a first air hose structure coupled to the one-way air valve,
wherein the air transferred by the one-way valve flows through the first air hose structure, and
wherein the air exits the first air hose structure proximate the distal second end of the paint chamber.

5. The device of claim 1 , further comprising:
a second air hose structure coupled between the air pump chamber and the one-way valve, said second air hose structure configured to provide air flowing from the air pump chamber to the one-way air valve;
wherein the air pump chamber comprises an air pump device, a pressure relief valve, and an air chamber.

6. The device of claim 1 , wherein the spray tip is removably coupled to the dispersion nozzle.

7. The device of claim 6 , further comprising a tip harness coupled to the sprayer body at a fourth position, wherein the spray tip is further coupled to the tip harness.

8. The device of claim 1 , wherein the atomized paint comprises an undiluted liquid paint product.

9. The outdoor paint sprayer of claim 8 , wherein the nozzle assembly is configured to dispense an atomized liquid paint product in a particular dispersion pattern.

10. The device of claim 1 , wherein the nozzle feature further comprises a vortex chamber between the spray tip and the dispersion nozzle, and
wherein the vortex chamber receives the liquid paint product from the plurality of orifices of the dispersion nozzle.

11. The device of claim 10 , wherein the swirl chamber is configured such that at least a portion of the liquid paint product is set into a vortex motion.

12. An outdoor paint sprayer device comprising:
a sprayer body;
a paint chamber coupled to the sprayer body at a first position;
an air pump chamber coupled to the sprayer body at a second position different than the first position;
a nozzle assembly coupled to the sprayer body at a third position different that the first position and the second position, wherein the nozzle assembly comprises a spray tip removably coupled to a dispersion nozzle;
a trigger mechanism for providing an indication to dispense paint from the paint chamber;
an air hose structure coupled between the air pump chamber and the paint chamber; and
a paint hose structure coupled between the paint chamber and the nozzle,
wherein the air pump chamber comprises at least a first valve assembly, and the paint chamber comprises at least a second valve assembly.

13. The device of claim 12 wherein the dispersion nozzle comprises a plurality of orifices.

14. The device of claim 12 wherein the coupling of the spray tip and the dispersion nozzle comprises a vortex chamber,
wherein the vortex chamber is configured such that at least a portion of the liquid paint product is set into a vortex motion.

15. The device of claim 12 , wherein the paint chamber comprises a proximal first end and a distal second end,
wherein the proximal first end of the paint chamber is removably coupled to the sprayer body,
wherein the air hose structure extends through the proximal first end of the paint chamber and terminates at the distal second end of the paint chamber such that air travelling through the air hose structure exits the air hose structure proximate the distal second end of the paint chamber.

16. A device for dispensing an undiluted liquid paint, said device comprising:
a sprayer body comprising at least one nozzle assembly and at least one valve assembly;
an air pump chamber coupled to the sprayer body, said air pump chamber comprising a pressure relief valve assembly, a pump mechanism, and a pump chamber port, the pump chamber port comprising a first air hose structure coupled with a one-way air valve of a paint chamber, wherein air traveling through the air hose structure exits the air hose structure into the paint chamber; and
the paint chamber comprising a proximal first end coupled to the sprayer body and a distal second end, the one-way air valve, and a second air hose structure coupled with the one way air valve opposite the first air hose structure,
wherein air traveling through second air hose structure exits the second air hose structure proximate the distal second end of the paint chamber, and wherein the paint chamber is separate from the air pump chamber.

17. The paint spraying device of claim 16 , wherein the at least one nozzle assembly comprises:
a spray tip and a dispersion nozzle, said spray tip removably coupled to said dispersion nozzle, said dispersion nozzle coupled to said sprayer body.
