  • Impeller module of snow drop water ball
    Patent number: 6895703
    Abstract: An impeller module of snow drop water ball includes an magnet driven impeller module attached on the anti-leak rubber plug for propelling the snow drops and turning the decoration in a glass dome. The magnet driven impeller module has a blade ring which is magnetically couple with a magnetic rotor, and drive by the magnetic rotor from outside of the snow drop ball. Using the impeller module embodiment of the present invention, the anti-leak rubber plug shall no longer in need of forming a shaft hole, so as can structurally solve the long-suffering liquid leakage problem of the snow drop water ball and prolonging its service life.
