A water pump motor comprising:

• a housing, said housing comprising an air inlet pipe, a downwardly extended bottom shell, a conical water guide chamber defined within said bottom shell, said conical water guide chamber having a diameter gradually increasing from a top side of said bottom shell toward a bottom side of said bottom shell, a plurality of water inlets through said bottom shell in fluid communication with said water guide chamber, an inside air passage axially provided in said bottom shell in communication between said air inlet pipe and said water guide chamber, and an outer thread extended around the periphery of said bottom shell;
• a motor shaft provided inside said housing;
• a vane wheel fastened to said motor shaft, said vane wheel having triangular vanes radially arranged at a top side around said motor shaft;
• a hollow water outlet pipe holder coupled to said bottom shell, said water outlet pipe holder having radial dampers equiangularly spaced around an inside wall thereof and an outer thread extended around the periphery thereof;
• a water outlet pipe coupled to said water outlet pipe holder for free rotation through 360° and adapted to guide water out of said water guide chamber;
• and
