[0002] In recent years, with the continuous development of magnetic stirring technology, its application in the field of liquid mixing has gradually attracted attention. Magnetic stirrers use the principle of magnetic field to generate rotational motion inside the container through magnetic stirring bars, thereby achieving liquid mixing. Compared with traditional electric stirrers, magnetic stirrers have the advantages of no need for external power supply, good stirring effect, and easy operation.

[0003] However, the magnetic stirrers currently on the market still have certain limitations in design and performance. As the integration of such equipment is realized and the safety level is improved, the convenience of equipment operation is gradually reduced, especially after the experiment is completed, the reaction vessel cannot be separated from the hot oil bath conveniently and in time, which brings great inconvenience to the experimental operators.

[0004] For example, a Chinese patent discloses "a liftable heat-collecting magnetic stirring device" (patent number: CN200920258862.9), which includes a bath pot, which is arranged in a hollow shell composed of an outer shell, and the upper part of the shell composed of the outer shell has a groove, and the bath pot is arranged in the groove, and its bottom is in contact with the upper platform of the lifting platform.

[0005] However, the above-mentioned magnetic stirring device cannot apply uniform stress to the bath pot through a mechanical structure to separate it from the magnetic stirrer. Utility Model Content

DETAILED DESCRIPTION

[0021] The utility model provides a magnetic stirrer for liquid mixing, such as Figure 1-3 As shown, it includes a base 11, a stirring power device 12, a support frame 13, a cooperative mechanism, an end cover 20 and a bearing tile 24. The stirring power device 12 is fixedly arranged in the base 11. The stirring power device 12 has the same structure as the prior art and is provided with an insulating layer resistance heating wire. The stirring power device 12 drives the internal permanent magnet to rotate through an electric motor, thereby driving the stirring rotor in the bath pot to rotate for stirring. The support frame 13 is fixedly arranged at the center of the base 11, and the end cover 20 is fixedly arranged on the upper side of the base 11. The end cover 20 and the base 11 are detachably connected. A limited slideway 21 is provided in the end cover 20, and a limited slider 22 is slidably provided in the limited slideway 21. The cooperative mechanism is arranged between the end cover 20 and the base 11. The cooperative mechanism is used to make the limited sliders 22 synchronously approach or move away from each other. The bearing tile 24 is detachably connected to the upper side of the limited slider 22. A placement cavity 25 is provided in the load-bearing tile 24. The bottom wall of the placement cavity 25 gradually tilts downward from the side away from the center inward, and the placement cavity 25 is used to place the bath pot.

[0022] like Figure 2-Figure 3 As shown, the cross section of the limiting slideway 21 is I-shaped, and at least three limiting slideways 21 are provided, and the three limiting slideways 21 are arranged in a ring array along the end cover 20 .

[0023] A positioning groove 23 is provided in the limit slider 22, and a connecting block 26 is fixedly provided at the bottom end of the load-bearing tile 24. An assembly block 27 is fixedly provided on the end face of the connecting block 26 close to the limit slider 22. The assembly block 27 fits in the positioning groove 23, and the connecting block 26 corresponds to the limit slider 22 one by one. The limit slider 22 drives the connecting block 26 to move synchronously through the assembly block 27, thereby driving the load-bearing tile 24 to move.

[0024] The cooperative mechanism includes a driving disk 14, a driving gear 15 and a connecting head 16. The driving disk 14 is rotatably connected to the upper side of the support frame 13. The lower end surface of the driving disk 14 is provided with a toothed disk, and the upper end surface of the driving disk 14 is provided with a spiral pattern. The base 11 is rotatably connected with the connecting head 16. The connecting head 16 is fixedly provided with a driving gear 15 on one side of the connecting head 16 close to the driving disk 14. The driving gear 15 is located on the lower side of the driving disk 14. The outer cylindrical surface of the driving gear 15 is provided with gear teeth. The outer cylindrical surface of the driving gear 15 is meshed with the toothed disk at the lower end of the driving disk 14. The lower end surface of the limiting slider 22 is provided with spur teeth. The spur teeth at the lower end of the limiting slider 22 are meshed with the spiral pattern at the upper end of the driving disk 14.

[0025] A connecting groove 17 is defined in the connecting head 16 at a side away from the axis of the base 11 .

[0026] The bath is placed in the placement cavity 25, and the square pin is manually inserted into the connecting groove 17 for rotation. The square pin drives the driving gear 15 to rotate through the connecting head 16, and the driving gear 15 drives the driving disc 14 to rotate through the toothed disc at the lower end of the driving disc 14. The driving disc 14 drives the limiting sliders 22 to move away from each other through the spiral pattern on its upper surface, so that the limiting sliders 22 adjust the distance between the load-bearing tiles 24 through the connecting block 26, so that the bath is located in the placement cavity 25.

[0027] When the stirring is completed, the square pin is reversed to drive the bearing tiles 24 to move closer to each other. Due to the bottom wall of the bearing tiles 24 that gradually slopes inward, the inclined force causes the bottom end surface of the bath to be squeezed and move upward, thereby separating the bath from the bearing tiles 24, making it easy for the user to separate the bath from the magnetic stirrer in time to protect the magnetic stirrer.

[0028] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
