[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] like Figure 1 As shown, this embodiment discloses a magnetic stirring device, including a container body 2. A magnet 7 is placed on the bottom surface of the container body 2. The magnet 7 is rotated by a magnetic force generator device 1. The magnetic force generator device 1 is located below the container body 2, and the lower end surface of the container body 2 abuts against the upper end surface of the magnetic force generator device 1. The magnetic field changes generated by the magnetic force generator device 1 enable the magnet 7 to rotate. The magnetic force generator device 1 actually controls the position changes of the magnet 7, including making the magnet 7 rotate clockwise, counterclockwise, and keep it in any position.

[0024] like Figure 1 As shown, the cavity inside the container body 2 serves as the stirring chamber. A top cover 3 is installed on the top of the container body 2. A second fixing seat 32 is installed on the top cover 3. The second fixing seat 32 is inserted into the top cover 3 and is fixedly connected to the top cover 3. A turntable 6 is installed on the second fixing seat 32. The second fixing seat 32 is inserted into the turntable 6. The second fixing seat 32 and the turntable 6 are coaxial. The second fixing seat 32 and the turntable 6 are connected by a second bearing 61. The turntable 6 can rotate along its own axis.

[0025] like Figure 1 As shown, a fixed seat 31 is installed on the top of the top cover 3, and a lifting seat 4 is installed on the fixed seat 31. The outer wall of the lifting seat 4 is threadedly connected to the fixed seat 31, and the lifting seat 4 can move up and down. A lifting block 5 is installed on the inner wall of the lifting seat 4 through a bearing 41. The lifting block 5 passes through the top cover 3, or more precisely, through the fixed seat 32. The lifting block 5 includes a base plate 51 located at the bottom, which is below the top cover 3. The upper surface of the base plate 51 abuts against the lower surface of the turntable 6 and is sealed by a sealing ring 8 to prevent liquid from entering the bearing 61 during stirring. By setting up the lifting seat 4, when the lifting seat 4 moves upward, it pulls up the base plate 51, causing the base plate 51 and the turntable 6 to press the sealing ring 8 tightly, forming a better sealing effect. When the turntable 6 rotates, it drives the lifting block 5 to rotate together.

[0026] like Figure 1 As shown, a rod 62 is mounted on the turntable 6. The rod 62 is located on both sides of the turntable 6 and can rotate around the axis of the turntable 6. The rod 62 extends into the bottom of the container 2, and the lowest position of the rod 62 is lower than the highest position of the magnet 7. (Combined with...) Figure 1 , Figure 4 When magnet 7 rotates, both ends of magnet 7 along its length can abut against rod 62 and drive rod 62 to rotate.

[0027] like Figure 1 As shown, a stirring plate 63 is mounted on the rod body 62. The stirring plate 63 is located above the magnet 7. The stirring plate 63 has an extension body 631, the surface of which is parallel to the axis of the turntable 6. Figure 1 , Figure 3 The extension body 631 is located on both sides of the stirring plate 63. When the stirring plate 63 rotates around the axis of the turntable 6, the extension body 631 creates a stirring effect.

[0028] like Figure 1 As shown, a movable block 64 is mounted on the rod 62, passing through the movable block 64. The movable block 64 is located above the magnet 7, and its upper end abuts against the stirring plate 63. The movable block 64 can move up and down along the outer wall of the rod 62 to drive the stirring plate 63 to move synchronously. Specifically, combined with Figure 1 , Figure 2 The movable block 64 has multiple grooves 641 on its outer periphery, with each groove 641 axially penetrating the movable block 64. A magnet 65 is inserted into each groove 641. The magnetic poles at the bottom of magnet 65 repel the magnetic poles of magnet 7 located below it. When the distance between magnet 7 and magnet 65 decreases, magnet 65 rises; when the distance increases, magnet 65 falls back down under the influence of gravity. The distance between magnet 7 and magnet 65 is controlled by the magnetic force generator device 1, which controls the position of magnet 7. When magnet 7 is in contact with rod 62, the distance between magnet 7 and magnet 65 is at its minimum; when magnet 7 separates from rod 62, the distance between magnet 7 and magnet 65 increases.

[0029] The surface of the stirring plate 63 is perpendicular to the axis of the turntable 6, so that the moving block 64 drives the stirring plate 63 to move up and down to create a stirring effect.

[0030] like Figure 1 As shown, a limit block 66 is installed on the rod body 62. The limit block 66 is located below the moving block 64. When the moving block 64 is in the lower limit position, the bottom of the moving block 64 abuts against the upper end of the limit block 66.

All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
