A mixing system typically for use in a container for mixing its contents, the mixing system including a cap unit, an extension unit and a magnetic mixing unit that is attached to the cap unit by the extension unit. The magnetic mixing unit can be folded to permit insertion and/or removal of the system via a mouth of the container. The extension unit and magnetic mixing unit connect via a hinge formed by upper and lower hinge portions that meet at a pivot point. The hinge portions extend from the pivot point along a first axis. The magnetic mixing unit includes a first magnetic elongate member that extends from the lower hinge portion along a second axis that is substantially perpendicular to the first axis, and a second magnetic elongate member that extends from the lower hinge portion along the second axis in the opposite direction relative to the first elongate member. The magnetic member(s) may be provided by a plastic coated magnetic stir bar.

A device for storing and circulating drinking water with vortex flow includes a base, a tank and an actuator housed in the base and configured to circulate the drinking water stored in the tank with vortex flow. The base includes an inlet port through which the drinking water is received and an outlet port through which the drinking water is dispensed. The tank is mounted on the base with a sealed engagement and is configured to store the drinking water. The tank has spherical or egg shape and includes an air inlet on an upper portion of the tank through which air can flow in and out of the tank.

A cooling and heating cabinet according to an embodiment of the present invention may comprise: an inner case having a storage space provided therein; an outer case which is disposed surrounding the inner case and forms an insulation cavity between the outer case and the inner case; a thermoelectric element module disposed in the insulation cavity; a separation panel disposed inside the inner case and having a plurality of through-holes; an agitating part disposed between the separation panel and the bottom surface of the inner case, and having a magnet and an agitating fan that rotates with the magnet; and a magnetic field-generating part disposed outside the outer case, and generating a magnetic field to rotate the magnet.

A colloidal brewing system has a transparent container assembly with a watertight bottom portion and an open top portion, the container assembly adapted to contain water. A removable lid electronic housing with two replaceable electrically charged silver rod members is disposed on a bottom portion of the lid member, the rod members extending substantially to near the bottom of the container assembly. A magnetic stir assembly substantially centers an interior bottom portion of the container assembly and to rotate, in the water, on a parallel plane to the bottom portion. A receiver and transmitter coil assembly are disposed within a base container assembly, the base container assembly designed to gravitationally support the watertight bottom portion of the transparent container assembly, the receiver coil and transmitter coil assembly inductively coupled to the magnetic stir assembly. The inventive concept has a rechargeable battery, a control panel, power port members, and handle member.

In accordance with aspects and embodiments, a magnetically driven liquid dispersion device is provided comprising a rotor, a funnel, and a rotary sprayer. The rotor is received by the funnel comprises an Archimedes screw and at least one diametric rotor magnet. The sprayer receives the funnel and comprises at least one diametric sprayer magnet. Application of an external rotating magnetic field generated by, for example, magnetic stirrer, causes the rotor to rotate within the funnel. Rotation of the rotor causes rotation of the sprayer about the funnel.

A device for mixing liquids and solids in liquids using vibration includes an electromagnetic drive, a drive shaft arranged coaxially with the electromagnetic drive, with drive shaft having a mixing member and either a permanent magnet or a magnetisable element excited by the electromagnetic drive to cause vibration for transmission to the mixing member, and a system of flat spring elements including a first spring element arranged parallel to the drive shaft and a second spring element arranged perpendicularly to the drive shaft and connected to the permanent magnet or the magnetisable element.
