  • Patent number: 8056284
    Abstract: An auto-irrigation apparatus is provided. A control panel and a water-level indicator light are inserted in a side of an irrigating case. A water pump, a cell box, and a control circuit are inserted in the irrigating case. The control panel, water-level indicator light, cell box, and water pump are coupled to the control circuit. A solar panel is embedded in each of two cover panels. Each of the two cover panels are mounted on opposite sides of the irrigating case. The embedded solar panels are coupled to the cell box. A water conduit adapter is connected to an outlet of the water pump. A planter box is placed in the irrigating case above a built-in water reservoir so that the water conduit adapter passes through an aperture in the planter box. Then, the water conduit adapter is connected to a spray pipe positioned above the planter box.

  • Publication number: 20100098555
    Abstract: A submersible water pump device is provided. The submersible water pump device includes a housing that contains a stator and windings and a control circuit. A rotor with curved impeller blades, which is contained within the stator attached to the windings, is inserted into the proximal end of the housing. A filter and volute, which cover the curved impeller blades of the rotor, are removably attached to the housing. The control circuit detects the polarity of the magnetic field of the rotor to control when to turn the motor on, so that the rotor only runs in one direction to increase the pump's efficiency using the curved impeller blades.
