  • Patent number: 10112204
    Abstract: A tank holding a quantity of liquid releasably connects to an electric pump module through a connector to provide a portable sprayer. The tank connects to a feed line that supplies spray nozzle with the liquid. The connector combines a quick disconnect connector with a pressure relief valve. The electric pump module includes an electric pump, a switch assembly, and a check valve. The electric pump module directs gas through the check valve into the connector to increase the gas pressure in the tank and force the liquid in the tank to flow through the feed line and out the spray nozzle. The switch assembly turns off the electric pump when the gas pressure in the tank exceeds a predetermined limit while maintaining the flow of liquid through the spray nozzle.

  • Patent number: 8672364
    Abstract: A quick disconnect device for connecting a sprayer tank to a portable pump assembly has a tubular body with an internal passageway for conveying gas between the sprayer tank and the portable pump assembly. A first plunger member is mounted within the internal passageway of that device for moving reciprocally between the sprayer tank and the portable pump assembly. A second plunger member, mounted within the internal passageway, moves reciprocally between the sprayer tank and the portable pump assembly. A first resilient member urges the first plunger member away from the sprayer tank to prevent gas from flowing into the sprayer tank. A second resilient member urges the second plunger member toward the sprayer tank to prevent gas from flowing out of the sprayer tank. The first plunger member moves toward the sprayer tank to overcome the spring constant of the first resilient member to direct gas from the portable pump assembly into the sprayer tank.
