[0002] A magnetic stirrer is a commonly used mixing device for liquid mixing, especially for low-viscosity liquids or solid-liquid mixtures. It uses the interaction between the magnetic field and the magnetic stirrer. When the magnetic field changes, the magnetic stirrer rotates, thereby stirring the liquid in the container to achieve mixing and homogenization of the liquid. It can effectively mix liquids and is widely used in laboratories.

[0034] When using the magnetic stirrer to prevent the stirring liquid from splashing, Figure 1 , Figure 3 , Figure 4 and Figure 6 As shown, first, place the container 18 containing the solution in the middle of the front end of the base 1, and then pull the movable pull rod 7 downward to slide between the movable pull rod 7 and the side block 6, and the movable pull rod 7 drives the spring 8 to move downward, so that the spring 8 squeezes the fixed block 9, and at this time, the fixed block 9 undergoes elastic deformation, and the fixed block 9 is disengaged from the fixing hole on the movable plate 4, thereby releasing the limit between the movable plate 4 and the base 1, and then pull the movable plate 4 to slide between the movable plate 4 and the base 1, and the movable plate 4 drives the clamping plate 5 to extend and retract on the base 1, so that the clamping plate 5 clamps and fixes the container 18, and fixes the container 18 at the corresponding position at the front end of the base 1, and then directly release the movable pull rod 7, at this time, the spring 8 restores its elastic deformation, drives the fixed block 9 to move upward and engage in the fixing hole at the corresponding position in the middle of the movable plate 4, thereby facilitating the limit between the movable plate 4 and the base 1;

[0035] The clamping and fixing of the container 18 by the clamping plate 5 can prevent the container 18 from shifting during the stirring process, thereby ensuring the stability during the stirring process. Figure 5 and Figure 7 As shown, in combination with the setting of the anti-splash mechanism 10, the anti-splash mechanism 10 is composed of an anti-splash cover plate 11, a mounting block 12, a mounting rod 13, a mounting sleeve 14 and a mounting plate 15. By pulling the mounting rod 13 downward, the mounting rod 13 drives the mounting plate 15 to slide with the vertical rod 16, so that the mounting rod 13 drives the anti-splash cover plate 11 to engage with the upper end of the container 18, and a sealing ring is fixed at the lower end of the container 18, and the sealing ring is fitted between the anti-splash cover plate 11 and the container 18, and then by rotating the fixing bolt 17, the fixing bolt 17 and the mounting plate 15 as well as the fixing bolt 17 and the vertical rod 16 are all threadedly connected, and the fixing bolt 17 is used to limit the mounting plate 15 and the vertical rod 16, so that the anti-splash cover plate 11 is fixed to the upper end of the container 18, and the lower end of the anti-splash cover plate 11 is fixedly connected with a fixing column 19, and the lower end of the fixing column 19 is rotatably connected with a magnetic stirring block 20, and the magnetic stirring block 20 is correspondingly arranged with the magnetic block 3;

[0036] Then, the device is connected to the power supply, and the motor 2 installed at the front end of the base 1 is started. The motor 2 drives the magnetic block 3 to rotate. Through the induction between the magnetic poles, the magnetic block 3 drives the magnetic stirring block 20 to rotate in the container 18, so as to stir the liquid. In addition, during the stirring process, the anti-splash cover 11 is engaged with the upper end of the container 18, which can effectively prevent the liquid from splashing outward and causing waste, and prevent pollution to the surrounding environment. When the stirring is completed, the power is turned off, the fixing bolt 17 releases the limit between the mounting plate 15 and the vertical rod 16, and the mounting rod 13 is pulled upward. The mounting rod 13 drives the anti-splash cover 11 to move upward, and the magnetic stirring block 20 is pulled out of the container 18, and then the clamping of the container 18 is released, and the container 18 can be removed. In addition, combined with Figure 2 As shown, the mounting sleeve 14 threadedly connected to the front end of the mounting rod 13 can be rotated to disengage the mounting sleeve 14 from the mounting rod 13, thereby loosening the limit between the mounting rod 13 and the mounting block 12, and then the anti-splash cover 11 is pulled forward, and the anti-splash cover 11 drives the mounting block 12 to disengage from the mounting rod 13, thereby facilitating the disassembly and cleaning of the anti-splash cover 11 and the magnetic stirring block 20 to prevent residue.
