    Abstract: Various embodiments concern a handheld paint sprayer for spraying a paint. The sprayer can comprise a shell body comprising a door that, when opened, exposes an opening into an interior of the shell body, the door configured to close over the opening. The sprayer can further comprise a trigger connected to a handle, a motor in the interior, and a paint reservoir connected to the shell body. The sprayer can further comprise a nozzle in fluid communication with the reservoir and a pump located in the interior of the shell body. The pump is operated by the motor, the pump configured to pump the paint from the reservoir out of the nozzle as a spray. The pump is removable from the interior of the shell body through the opening when the door is opened but is not removable through the opening when the door is closed.

    Abstract: A handheld fluid sprayer (10) is configured to draw spray fluid from a reservoir (14) mounted on the fluid sprayer and eject the spray fluid through a nozzle (32). The reservoir is removably mounted to the fluid sprayer. A filling apparatus can connect to the reservoir at the same interfaced that the reservoir (14) connects to the fluid sprayer (10). The filling apparatus can be used to refill the reservoir (14).

    Abstract: A fluid sprayer includes a pump and an electrostatic module configured to provide an electrostatic charge to spray fluid. The electrostatic module is electrically connected to a conductive component of the fluid sprayer, such as a fluid displacement member, fitting, cylinder, or spray tip, to charge the spray fluid via the conductive component. The fluid is electrostatically charged prior to exiting the fluid sprayer.

    Abstract: A spray tip includes a body portion with an aperture extending through the body portion from an aperture inlet to an aperture outlet, and a handle portion attached to the body portion. The handle portion is configured to rotate the body portion. A retainer with an upstream end and a downstream end is positioned in the aperture of the body portion. A pre-orifice piece with an upstream end and a downstream end is positioned in the aperture of the body portion. A tip piece with an upstream end and a downstream end is positioned in the aperture of the body portion. The downstream end comprises an outlet nozzle.

    Abstract: A fluid dispensing device includes an electrostatic discharge protection system. Accumulation and discharge of electrostatic energy created by operation of the device is reduced or prevented by the electrostatic discharge protection system without an earth ground connection. The electrostatic discharge protection system may include a number of features, such as a static wick, nonconductive components that electrically isolate the spray tip of the device, nonconductive isolation barriers, nonconductive fluid reservoir and suction tube components, a nonconductive coating of a control valve component, and a nonconductive spring retainer of the control valve.

    Abstract: A handheld sprayer comprises a housing, a turbine, a spray tip, a hopper and a trigger. An air flow passage extends through the housing. The turbine is configured to generate an airflow within the air flow passage. The spray tip is positioned to receive airflow from the air flow passage. The hopper is connected to the housing and is configured to discharge a fluid into the air flow passage. The trigger is mounted to the housing to control discharge of the hopper into the flow passage and airflow form the turbine. In different embodiments, the trigger controls airflow from the turbine to the spray tip or the hopper or both. Additionally, a method for spraying a fluid from a handheld sprayer comprises controlling airflow from a turbine and discharge from a hopper into a passage using a combined actuator.
