ABSTRACT:
A novel automatic tree waterer is provided herein. It is adapted to be connected to a stand which holds a tree, e.g. a Christmas tree, in an upright position. The waterer includes a hollow support base and a hollow two-piece body section. The lower body section is assembled to the support base by means of a slide coupled lip/coupling support lip to be airtight and watertight. The upper body section is assembled to the lower body section by means of male/female threads to be airtight and watertight. The upper body includes a male threaded upper neck. A hat including an inner well with interlock threads is assembled to the upper body by means of the male/female threads to be airtight and watertight. A water outlet is provided from the interior of the body section. A flow controller unit is connected to the water outlet to close the water outlet to enable filling the interior of the hollow two-piece section with water. A hose is adapted to be connected between the flow controller and the stand which holds the tree. Once the flow of water is commenced, a cyclic automatic flow of water ensues. The water will not flow unless air is allowed to enter through the tube. Thus, when the end of the tube is submerged in water, no water can flow.
