Abstract
A pressure-increasing device driven by liquid includes a body, a power unit, a drive unit and a bottom base. The body has a housing provided with an inner tube in the interior, and a water passage formed between the housing and the inner tube. A drive unit is positioned at the bottom of the body, having a plate body provided thereon with a plurality of centrifugal blades. A plurality of extension wings are respectively disposed at preset locations of the outer ends of the centrifugal blades. Each extension wing extends outward to a preset position in the water passage of the body for holding up the water thereon and pushing it upward by the driving force produced by its rotation to produce a powerful pressure-increasinng force for pushing water easily outward.
