  • Wearable spraying device
    Patent number: 9296002
    Abstract: A sprayer portable on the back for spraying liquids comprises a tank (2), a hand lever (4), a pump (12) and a pressure vessel, wherein the pressure vessel is formed by a hollow space in the hand lever (4) and the pump (12) is arranged in the hollow space. The piston rod (13) of the pump is rotatably connected to a lever element (15) of the hand lever. A connecting sleeve (16) for a hose with a spray nozzle is integrated in the hand lever. The compact configuration of the sprayer allows a larger tank volume and more convenient operation. The sprayer can be manufactured at low cost due to the small number of components.
