Abstract
Described herein is an apparatus for applying fluids to a surface. The apparatus includes a nozzle coupled to a pressurized gas supply source and a fluid supply source. The nozzle includes outer conduit and an inner conduit ¥positioned such that a gap is formed between the inner and outer conduits. The outer conduit is coupled to the pressurized gas supply source. The inner conduit is coupled to the fluid supply source. Gas passed through the gap between the inner and outer conduits pulls fluid from the fluid supply source and into the gas stream.
Claims35
A fluid spraying nozzle comprising:
- an outer conduit;
- and
- an inner conduit positioned within at least a portion of the outer conduit such that a gap is formed between the outer conduit and the inner conduit;
- wherein a back portion of the outer conduit is coupled to a pressurized gas supply source,
- wherein a back portion of the inner conduit is coupled with a fluid supply source, the fluid supply source being configured to supply a non-pressurized fluid, the fluid comprising a liquid, a solid, or a mixture of a liquid and a solid, and wherein a front portion of the inner conduit is configured to allow ejection of the fluid during use,
- wherein the inner conduit and the outer conduit are composed of a flexible material, and wherein the front portion of the inner conduit and the front portion of the outer conduit move when gas is ejected from the outer conduit, and wherein the fluid is pulled from the fluid supply source through the inner conduit when gas is ejected from the outer conduit such that the fluid is mixed with the ejected gas,
- wherein the nozzle further comprises a regulating member positioned proximate to the outer conduit, and an annular whisk coupled to an opening end of the regulating member.

A fluid spraying apparatus comprising:
- a body;
- a nozzle disposed in the body, the nozzle comprising an outer conduit and an inner conduit positioned within at least a portion of the outer conduit such that a gap is formed between the outer conduit and the inner conduit;
- a pressurized gas supply source coupled to the outer conduit;
- and
- a fluid supply source coupled to the inner conduit, the fluid supply source being configured to supply a non-pressurized fluid, the fluid comprising a liquid, a solid, or a mixture of a liquid and a solid, wherein the fluid supply source comprises a fluid container that is removably attached to the body;
- wherein a back portion of the outer conduit is coupled to the pressurized gas supply source,
- wherein a back portion of the inner conduit is coupled to the fluid supply source, and wherein a front portion of the inner conduit is configured to allow ejection of the fluid during use,
- wherein the inner conduit and the outer conduit are composed of a flexible material, and wherein the front portion of the inner conduit and the front portion of the outer conduit move within the body when gas from the pressurized gas supply source is ejected from the outer conduit, and wherein the fluid is pulled from the fluid supply source through the inner conduit when gas is ejected from the outer conduit such that the fluid is mixed with the ejected gas.
