Automatic water dispenser for horticulture use in watering plants

摘要

The dispenser consists of a diffuser (10) mounted on the end of a flexible pipe (12) of which the opening and closure is effected by the moving item (20) made up of a valve (21) of which the rod (22) is connected to a sink head (23) directed to the discharge (11) of the diffuser (10). The valve (21) can seal against a seat (14) with the interposing of an `o-ring' seal (15) which lodges in the circular area defined by the internal conical wall of the diffuser and the seat (14). Adjustment can be made in the distance between the valve (21) and the sink head (23). When the diffuser is placed upwards the water can flow until its level reaches the top of the diffuser and the sink head (23) floats to restrict the flow, and if used to automatically fill containers, the floatability of the sink head will rise further to eventually cut off the flow. If the diffuser is placed downwards on a level surface, the sink head will open the valve to allow a controlled flow of water.
