    摘要： 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.

    摘要： A handheld sprayer comprises a housing, a turbine, a spray tip, a hopper and a bleed line. 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 bleed line is configured to direct a portion of the airflow from the turbine to the hopper. Additionally, a method for spraying a fluid from a handheld sprayer comprises directing a portion of an airflow from a turbine into a hopper to assist in discharging fluid from the hopper into a passage connected to a spray tip and the airflow from the turbine.

    摘要： 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.

    摘要： A handheld sprayer includes a housing, a turbine, a spray tip, and a hopper. 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 configured to discharge a fluid into the air flow passage. In one embodiment a valve is positioned within the air flow passage and configured to control the airflow from the turbine to the spray tip. In another embodiment, a voltage limiting circuit is configured to control voltage to an electric motor of the turbine to control speed of the turbine. In another embodiment, an air inlet control device is configured to control the air intake of the turbine.
