<p>A liquid stirring device comprises: a shell (1), a container (2), a container cover (3), a drive device (4), a suspending device (6), and a stirring head (5). The drive device (4) is arranged below the container (2); the suspending device (6) and the stirring head (5) are arranged in the container (2). The stirring head (5) is positioned in the container (2) through the suspending device (6); an upper part of the suspending device (6) is fixed on the container cover (3). A shaft of suspending device (6) includes an upper section (6.1) and a lower section (6.3); the upper section (6.1) and the lower section (6.3) are connected through an elastic connecting device (6.2). An upper part of the drive device (4) is provided with a magnet device (4.3), and a lower part of the stirring head (5) is provided with a magnet device (5.3); a lower part of the suspending device (6) is provided with a magnet device (6.4), and an upper part of the stirring head (5) is provided with a magnet device (5.4). The drive device (4) drives the stirring head (5) through the magnetic action of the magnet devices (4.3, 5.3), and together with the magnet device (6.4) at the lower part of the suspending device (6), positions the stirring head (5) through magnetic action. The liquid stirring device positions the stirring head (5) from the lower part through a magnetic force, and also positions the stirring head (5) from the upper part through a magnetic force, so that during rotation, the stirring head neither contacts the bottom of the container (2) nor contacts the suspending device (6), hence reducing the friction of the stirring head (5) during rotation, and improving the working efficiency.</p> |
