WATER JET DEVICE AND WATER DANCE SPEAKER

摘要

A jet device includes a base container in which a cover plate is mounted to define a chamber. A fan having blades is rotatably received in the chamber and includes internal magnetic elements mounted thereto. A drive unit including an electric motor is mounted externally to the base container and includes external magnetic elements that are driven by the electric motor to rotate about an axis. The internal and external magnetic elements correspond to each other and magnetic attraction forces are generated therebetween to drive the internal magnetic elements to rotate in unison with the external magnetic element so that the fan is rotate to induce a flow of liquid in the chamber. The flow liquid is guided to pass through holes formed in the cover plate to form jets of liquid above the cover plate. A top housing is mounted to the base container to confine the liquid jets.

主权项

1. A water jet device, comprising:
a base container having a hollow interior; a cover plate mounted in the base container and spaced from a bottom of the base container, the cover plate comprising a through hole defined therein, a chamber being defined between the cover plate and the bottom of the base container to receive liquid therein; a fan having at least one blade and rotatably received in the chamber of the base container and comprising an internal magnetic element attached thereto; and a drive unit mounted externally to the bottom of the base container and comprising an external magnetic element mounted thereto and rotatable by the driven unit, the external magnetic element corresponding to the internal magnetic element of the fan to generate a magnetic attraction force therebetween; wherein the drive unit is operable to rotate the external magnetic element about an axis and the internal magnetic element is driven by the external magnetic element through the magnetic attraction force therebetween to drive the blade of the fan to rotate in the chamber so that a flow of the liquid is induced in the chamber by the rotation of the blade of the fan, the liquid flow being guided to pass through the through hole formed in the cover plate to form a liquid jet ejecting above the cover plate.
