Abstract

A gas generating apparatus with separated water pump, comprising a delivery device, an electrolytic device and a water pump. The delivery device accommodates electrolyzed water. The electrolytic device is configured for electrolyzing electrolyzed water to generate hydrogen. The water pump comprises a stirring fan and a drive motor. The stirring fan is configured inside the delivery device to promote the electrolyzed water flowing. The drive motor is coupled to an outer surface of the delivery device and is configured for driving the stirring fan to promote the electrolyzed water flowing. In present invention, the flowing electrolyzed water driven by the separated water pump cools down the electrolytic device, and the drive motor is prevented from corroding by the electrolyzed water and the cooling efficiency of the drive motor is increased. Therefore, the operational safety is improved and the life of the gas generating apparatus with separated water pump is extended.
