Description

Technical Field

[0001] This utility model relates to the field of stirring mechanism equipment, specifically a multi-unit magnetic stirrer. Background Technology

[0002] A magnetic stirrer utilizes the property of like poles repelling each other in magnetic materials, driving the magnetic stir bar to rotate by continuously changing the polarity of the two ends of the base. A magnetic stirrer is a type of magnetic coupler. The magnetic coupler completely isolates the power output and input components of the stirring mechanism, and separates the motor reducer of the reaction vessel or tank from the stirring shaft inside the vessel or tank without contact, thus maintaining a completely enclosed state inside the vessel or tank.

[0003] However, traditional magnetic stirrers often have multiple independent bases. If the motor under one base fails, that base cannot be used properly, which greatly inconveniences users. Utility Model Content

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.

[0022] This utility model embodiment provides a multi-unit magnetic stirrer, such as Figure 1-4 As shown, the device includes a housing 1, a stirring device 2, and multiple test tube shaking mechanisms 7. The housing 1 has a slot. The stirring device 2 is located within the slot, and the multiple test tube shaking mechanisms 7 are slidably fitted onto the top of the housing 1. The stirring device 2 includes a support plate 17, a drive assembly 23, and two linkage rods 3. The support plate 17 is located inside the housing 1. The drive assembly 23 is slidably fitted onto the support plate 17, and the two linkage rods 3 are symmetrically arranged at both ends of the drive assembly 23. The linkage rods 3 are slidably fitted onto the top of the housing 1, and the drive assembly 23 is linked to the multiple test tube shaking mechanisms 7.

[0023] The drive assembly 23 includes multiple rotor drive mechanisms 22. The multiple rotor drive mechanisms 22 are slidably fitted on the support plate 17, and the multiple rotor drive mechanisms 22 are movably connected to each other.

[0024] The rotor drive mechanism 22 includes a motor 16, a sleeve 15, and a tray 5. The motor 16 is slidably fitted onto the support plate 17, and the sleeve 15 is fitted onto the output end of the motor 16. The tray 5 is disposed on the sleeve 15, and the magnetic pole gear 13 is located between the tray 5 and the motor 16. The magnetic pole gear 13 is disposed on the output end of the motor 16.

[0025] The rotor drive mechanism 22 also includes a first insert plate 19, a second insert plate 21, and an electromagnetic fixing block 18. The first insert plate 19 and the electromagnetic fixing block 18 are respectively disposed on both sides of the sleeve 15, and the first insert plate 19 and the second insert plate 21 on two adjacent rotor drive mechanisms 22 are movably inserted into each other. The electromagnetic fixing block 18 is disposed on the second insert plate 21, and the second insert plate 21 is magnetically connected to the first insert plate 19.

[0026] Multiple strip-shaped grooves 10 are evenly spaced along the thickness direction of the housing 1. Multiple through holes 11 are provided on the back of the housing 1, and a test tube shaking mechanism 7 is disposed on the strip-shaped grooves 10. The test tube shaking mechanism 7 includes a test tube holder 6, a secondary gear disk 12, an electric telescopic rod 14, a first insert plate 19, and a drive slider 20. The electric telescopic rod 14 is disposed within the strip-shaped groove 10, the drive slider 20 is disposed on the movable end of the electric telescopic rod 14, and the first insert plate 19 is horizontally disposed on the drive slider 20. The secondary gear disk 12 is slidably fitted onto the first insert plate 19, the test tube holder 6 is vertically disposed on the secondary gear disk 12, and the secondary gear disk 12 meshes with a magnetic pole gear disk 13.

[0027] The stirring device 2 also includes a transverse rocking mechanism 4, which comprises a frame 9 and a drive wheel 8. The frame 9 is mounted on two linkage rods 3, and the drive wheel 8 is mounted on the back of the housing 1. The drive wheel 8 is in contact with the frame 9.

[0028] Working principle: In use, the beaker is placed normally on the tray 5. The motor 16 is controlled to drive the magnetic gear disk 13 to rotate. The magnetic coupling causes the rotor inside the beaker to rotate and stir the beaker, thus completing the stirring work. When it is necessary to shake the test tube, the electric telescopic rod 14 can be controlled to drive the secondary gear disk 12 to move and engage with the magnetic gear disk 13. The rotation of the magnetic gear disk 13 is used to rotate and stir the test tube. At the same time, the drive wheel 8 can be controlled to drive the frame 9 to force the linkage rod 3 to drive the entire drive group 23 to shake laterally. Meanwhile, the secondary gear disk 12 moves back and forth on the insert plate 19 to complete the shaking of the test tube.

[0029] When one of the motors 16 fails, the independent rotor drive mechanism 22 cannot work. Therefore, the auxiliary gear disk 12 is still controlled to move between the two magnetic pole gear disks 13, so that the good motor 16 next to it can act as the drive source to drive the magnetic pole gear disk 13 on the damaged motor 16.

[0030] In summary, this multi-unit magnetic stirrer, through the coordinated arrangement of the housing 1, stirring device 2, and multiple test tube shaking mechanisms 7, ensures that the test tube shaking mechanism 7 engages with the rotor drive mechanisms 22 on multiple bases. Therefore, even if a single rotor drive mechanism 22 on a base fails, it will not affect normal use.
