Abstract
A multifunctional pure water maker includes a main body and a reverse osmosis module. The main body includes a base portion and a column extending from the base portion. A water container is removably placed on the base portion. A control cap is pivotally attached to the column and includes a compartment in an underside thereof. An outlet pipe is mounted in the control cap and has an end communicated with the reverse osmosis module. Water purified by the reverse osmosis module flows through the other end of the outlet pipe into the water container when the control cap is in a closed position covering an opening of the water container. A limit switch is mounted in the control cap such that the reverse osmosis module is activated to proceed with production of pure water when the control cap is moved to the closed position and that the reverse osmosis module is deactivated when the control cap is moved to an open position.
