Abstract:
1. A portable feeder for pets, comprising: a water storage bottle; a water tray, the water tray and the water storage bottle rotatably connected by a shaft hole in the water tray and a pivot on the water storage bottle; a bottle stopper and a curved sliding surface set on an inner base of the water tray, the curved sliding surface having a root at a top of the inner base, the bottle stopper having a hollow cylindrical shape with a middle section set with radial outlet holes for water flow out of the water storage bottle, the bottle stopper positioned in a water storage bottle mouth, which shares a central axis with the water storage bottle, a head of the bottle stopper configured to press against the root of the curved sliding surface to press the bottle stopper into the water storage bottle mouth and stop a flow of water from the water storage bottle when the water storage bottle is in a closed position in which the water storage bottle rests in the water tray; the head of the bottle stopper configured to move from the closed position against the root to a second position at an oblique surface at a bottom of the inner base when the water storage bottle is rotated about the pivot, wherein when the water storage bottle is rotated until perpendicular to the inner base of the water tray, the bottle stopper is still inside the water storage bottle mouth; wherein the water storage bottle is configured to move to an open position in which the central axis of the water storage bottle and the inner base of the water tray intersect at an obtuse angle of δ; wherein under pressure arising from the water storage bottle squeezed, the bottle stopper moves a distance along a bottle stopper axis towards an outside of the bottle mouth, a water flow path between the water storage bottle and the water tray is opened; and wherein when the water storage bottle ceases to be squeezed, water flow into the water tray is stopped.
