Insecticide sprayer and nozzle assembly

A fluid sprayer comprising:

• a tank containing fluid therein;
• a nozzle assembly in communication with the tank to receive fluid therefrom and to atomize the fluid;
• a blower assembly positioned upstream of the nozzle assembly for dispersing the atomized fluid from the nozzle assembly into the surroundings of the fluid sprayer;
• a discharge chute positioned downstream of the blower assembly into which the atomized fluid from the nozzle assembly is sprayed before being discharged upward and into the surroundings of the fluid sprayer;
• a pump located between the tank and the nozzle assembly;
• a low pressure line configured to deliver the fluid from the tank to the pump at a first pressure;
• a high pressure line configured to deliver the fluid from the pump to the nozzle assembly at a second pressure greater than the first pressure;
• a valve positioned between the nozzle assembly and the pump to regulate the pressure of fluid supplied to the nozzle assembly, wherein the valve is adjustable to regulate the pressure of fluid supplied to the nozzle assembly at different values, and wherein the adjustable valve includes an electrical actuator, and wherein the fluid sprayer further comprises a controller in electrical communication with the electrical actuator and operable to vary the regulated fluid pressure by activating the electrical actuator;
• and
• a sensor operable to detect an operating condition and provide an input signal to the controller, wherein the controller is operable to adjust the valve in response to the input signal to vary the regulated pressure of the fluid supplied to the nozzle assembly,
• wherein the operating condition is a speed or a pressure of an airflow generated by the blower assembly.
