A handheld computer device is configured to selectively receive a plurality of fluid output values from a paint sprayer and configured to operate in an accessible mode in which the handheld computer device is in a first location where wireless connectivity, via a continuous or near continuous communication path, to at least one of a network server or the paint sprayer is accessible or operate in an inaccessible mode in which the handheld computer device is in a second location out of range of the continuous or near continuous communication path to at least one of the network server or the paint sprayer.

Paint sprayer distributed control and output volume monitoring architectures

A spray roller system for application of architectural paints coating, includes an extension tube, a spray head mounted on a distal end of the extension tube, and the in-line valve with a trigger mounted on a proximal end of the extension tube, and a roller handle removable mounted on the extension tube adjacent the spray head. The spray roller system can spray and back roll a coating on a down stroke and roll on each up stroke. When the roller handle is removed from the extension tube, it can be used to hand roll sensitive wall areas. With the roller handle removed, extension tube, spray head, and in-line valve can be used as a spray extension to apply coatings in hard to reach areas.

Modular spray roller system

A sprayer for spraying fluid includes a pump, a motor that drives the pump, a drive cycle indicator, a wireless module configured to send and receive information, and control circuitry. The drive cycle indicator outputs an indication of cycle status of the pump. The control circuitry is configured to receive the plurality of cycle status indications of the pump, determine a plurality of output values representing paint spray fluid output volume over a plurality of time windows based on the plurality of cycle status indications of the pump, store the plurality of output values in memory, and cause the wireless module to transmit one or more of the stored plurality of output values externally from the sprayer.

An adapter allows direct connection of a handheld spray device to paint cans of varying dimensions. The adapter includes a cage for holding the paint can, a cap that connects the cage to the handheld spray device, and a gasket that seals the open upper end of the paint can to the cap. The adapter may also include a suction tube extension that is connectable between the pump inlet and the suction tube of the spray device. A can spacer insert is positionable in the cage to elevate paint cans of varying heights so that the upper ring of the paint can engages the gasket.

In airless spray tip assemblyshown in FIG., cylindercontains tipand is at one end of dead zone. Shutoffis comprised of balland seat. The needle seathas been mated to each tip assembly(See FIG.). By mating the tipand the seat assembly (shutoff)into one, the sealcan be moved out of the 'dead zone'thus reducing spit volume and energy storage.
