    Abstract: A handheld misting device, having a fluid tank that can be pressurized to force the contained fluid under pressure through a fluid delivery system, includes a hand-operated pump for injecting air into the fluid tank to pressurize the fluid tank. The pump includes a pump handle located at the bottom of the tank at one end of a rod, and a piston at the other end of the rod. The pump handle rotates in order to lock, in a retracted position, against the tank; the form factor of the handle conforms to that of the tank, to define an unbroken outer surface of the device when the handle is locked in the retracted position. A pressure-relieving air channel extends through the piston, the rod, and the pump handle to emit air out of the pump and into the environment when the fluid tank is at a maximum pressure.

    Abstract: An improved pressurized sprayer is provided. The pressurized sprayer includes a support frame, a modular power center, and a spray wand. The support frame defines an internal reservoir, and the modular power center includes a pump, a controller, and a battery, the pump being fluidly coupled to the internal reservoir via a quick-release connector. The spray wand is fluidly coupled to the pump via a discharge hose and includes an inverted pistol grip having a push-button trigger and a thumbwheel potentiometer for controlling flow-rate or pressure. The readily accessible nature of these controls allows the operator to meet the needs of a variety of applications, with all controls at a natural forefinger and thumb rest point. The heavier elements of the spray wand remain below the forearm and hand of the operator. This configuration enhances the ergonomic feel of the spray wand by maintaining a natural upright trigger position.
