Abstract:
A fluid dispensing device includes a housing and a reciprocating piston fluid pump coupled to the housing. The reciprocating piston fluid pump includes a piston. The piston is configured to pressurize at least one pumping chamber. A motor is connected to the reciprocating piston fluid pump to actuate the piston. A spray tip connected to an outlet of the at least one pumping chamber.
Abstract:
To assist the filtering from a tank into the inlet port of the pressure chamber of a sprayer, an additional pumping structure is attached to the pumping mechanism of the sprayer. A hose extends into the tank of the sprayer and draws fluid from the tank into the additional pumping structure. Fluid is pumped from the additional pumping structure via the hose to provide a jet of fluid upon a filter over the inlet port. The jet of fluid flushes the filter and retards the accumulation of debris thereon, thereby retarding the clogging of the filter.
Abstract:
The subject matter discloses a faucet inserted into a paint port of a painting apparatus to control flow of paint removed from the painting apparatus, the faucet comprising an external mold rotatably insertable into a paint port of a painting apparatus; wherein said external mold is spiral; an internal mold insertable into the external mold; a faucet valve to control flow of paint from the paint apparatus.
Abstract:
A solar powered portable mister includes at least one storage tank, a spray wand unit, a photovoltaics module, a battery, and a pump system. The at least one storage tank is utilized to store sunscreen so that the sunscreen can be efficiently and quickly sprayed to a large number of people through the spray wand unit. The pump system dispenses the sunscreen from the at least one storage tank and into the spray wand unit through a connector tube, where the pump system is powered from the battery and a power switch that is operated by the user. The photovoltaics module constantly recharges the battery during the operation of the solar powered portable mister as it increases the operational time of the solar powered portable mister.
Abstract:
In one example, a personal misting device is provided that includes a portable housing sized and configured to be held in one hand of a user, and also includes a fluid reservoir attachable to the portable housing. A fluid pump and motor are disposed within the portable housing, and the fluid pump is configured and arranged for fluid communication with the fluid reservoir. Additionally, a hose is provided that has a first end in fluid communication with the fluid pump, and a second end that is connected to a misting nozzle. Finally, a power supply operable to run the fluid pump is disposed in the housing.
Abstract:
A handheld airless fluid dispensing device comprises a pump, a drive element and an orifice element. The pump directly pressurizes a fluid. The drive element supplies power to the pump. The orifice element is connected to the pump and atomizes un-thinned architectural coating to a particle size of no greater than approximately 150 microns. The pump generates orifice pressures up to approximately 2.48 MPa and the orifice has an area of approximately 18.7 mm2. In one embodiment, the pump, drive element and orifice element are integrated into a handheld housing. In one embodiment, the pump comprises a reciprocating piston fluid pump comprising at least two pumping chambers configured to be actuated out of phase by at least one piston. In another embodiment, the reciprocating piston fluid pump comprises two pistons having different displacements that are linearly actuated by a wobble assembly driven by a gear reducer and an electric motor.
Abstract:
A sprayer attachment for a hand-supported power tool comprises a motion converting mechanism, a pumping mechanism, a spray assembly and a housing. The motion converting mechanism has an input shaft. The pumping mechanism is driven by the motion converting mechanism. The spray assembly is fluidly coupled to the pumping mechanism. The housing assembly couples the motion converting mechanism, the pumping mechanism and the spray assembly. The sprayer attachment may further comprise an anti-rotation bracket extending from the housing. The sprayer attachment may further be coupled to a handheld power tool, such as a cordless drill or a reciprocating saw, with the anti-rotation bracket.
Abstract:
A portable airless sprayer comprises a housing, a motor, a pump, a spray tip and a trigger. The motor is mounted to the housing. The pump is mounted to the housing and is driven by the motor. The spray tip assembly receives pressurized fluid from the pump. The trigger is configured to actuate the spray tip assembly and activate the motor. A method of operating a portable airless sprayer comprises moving a lever over a stroke, displacing a valve pin, and activating a motor. The valve pin is displaced with the lever to actuate a spray valve. The motor is activated with the lever to drive a pump that provides fluid to the spray valve.

Abstract:
An apparatus for performing grounds maintenance functions and dispensing a fluid includes a grounds maintenance device and a fluid spraying device. The spraying device includes a container mounted on the grounds maintenance device for holding the fluid, and a spraying member in communication with the container for spraying the fluid. The spraying member is moveable from a carrying position in which the spraying member is carried on the grounds maintenance device to a spraying position in which the spraying member is moveable independent of the grounds maintenance device.
