Description

Technical Field

[0001] This utility model relates to the field of magnetic stirrer technology, specifically a cell separation and heating magnetic stirrer. Background Technology

[0002] A magnetic stirrer is a common laboratory device that uses a magnetic field to drive a stir bar to mix liquids. Inside the stirrer is a magnetic rotor driven by a motor. When the motor is powered on, it rotates the magnetic rotor, generating a rotating magnetic field. A container filled with liquid is placed on the stirrer's worktable, and a magnetic stir bar is placed inside the container. Under the influence of the rotating magnetic field, the stir bar rotates in the same direction as the magnetic field, thus stirring the liquid in the container and ensuring it is thoroughly mixed.

[0003] However, existing magnetic stirrers cannot be replaced with different materials depending on the solution being stirred, which limits their flexibility in use. To address this issue, a cell separation heating magnetic stirrer is provided. Summary of the Invention

[0004] The purpose of this utility model is to provide a cell separation heating magnetic stirrer to solve the problems mentioned in the background art. To achieve the above objective, this utility model provides the following technical solution: a cell separation heating magnetic stirrer, including a stirrer, a fixed plate provided on the rear side of the stirrer, a lifting assembly provided on the fixed plate, a top plate provided at the top of the lifting assembly, a rotating column rotatably connected to the top of the top plate via a bearing, a cross fixedly sleeved on the rotating column, rotating rods rotatably connected to the four branches of the cross via bearings, a stirring element provided at the bottom of the rotating rod, the four stirring elements being made of different materials, a frame provided at the top of the top plate, and a drive assembly provided in the inner cavity of the frame.

[0005] Preferably, the bottom of the stirrer is provided with an anti-slip pad.

[0006] Preferably, the drive assembly includes a worm gear, a worm, and a turntable. The worm gear is fixedly sleeved on the outer wall of the rotating column. One end of the worm is rotatably connected to the left side of the inner cavity of the frame through a bearing, and the other end of the worm extends to the right end of the frame and is fixedly connected to a knob.

[0007] Preferably, the worm gear meshes with the worm wheel.

[0008] Preferably, the outer circumference of the turntable is provided with multiple anti-slip bars.

[0009] Preferably, the lifting assembly includes a screw, a knob, a movable cylinder, and a telescopic assembly. The screw is rotatably connected to the middle of the fixed plate via a bearing. The knob is located at the bottom end of the screw. The movable cylinder is screwed to the outer wall of the screw and fixedly connected to the bottom end of the top plate. The telescopic assembly is located between the top plate and the fixed plate.

[0010] Preferably, the telescopic assembly includes a telescopic cylinder, a telescopic rod, and a connecting assembly. The telescopic cylinder is disposed at the top of the fixed plate, the telescopic rod is slidably inserted into the inner cavity of the telescopic cylinder, the top end of the telescopic rod is fixedly connected to the bottom end of the top plate, and the connecting assembly is disposed in the inner cavity of the telescopic cylinder and fixedly connected to the outer wall of the telescopic rod.

[0011] Preferably, the connecting assembly includes a connecting groove and a connecting block.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] The height of the stir bar can be adjusted by the lifting component. After the beaker is placed on the stir bar, the lifting component drives the cross, rotating rod and stir bar to slide down and insert into the inner cavity of the beaker, which makes it easy to pick up and put down the stir bar. The operation is simple and convenient.

[0015] By configuring the drive components, the rotating column can drive the cross, rotating rod, and stir bar to rotate, thereby allowing stir bars of different materials to rotate above the beaker to stir the solution. This solves the problem that existing magnetic stirrers cannot be used with different materials depending on the solution being stirred, resulting in limited flexibility during use.

[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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figures 1 to 5 This utility model provides a technical solution: a cell separation heating magnetic stirrer, including a stirrer 1, a fixed plate 2 at the rear of the stirrer 1, a lifting assembly on the fixed plate 2, a top plate 3 at the top of the lifting assembly, a rotating column 4 rotatably connected to the top of the top plate 3 via bearings, a cross 5 fixedly sleeved on the rotating column 4, and rotating rods 6 rotatably connected to the four branches of the cross 5 via bearings. Stirring elements 7 are provided at the bottom of the rotating rods 6, and the four stirring elements 7 are made of different materials. A frame 15 is provided at the top of the top plate 3, and a drive assembly is provided inside the frame 15. Through the lifting assembly, the stirring element can be adjusted... The height of the stir bar 7 is adjustable. After the beaker is placed on the stirrer 1, the lifting component drives the cross bar 5, the rotating rod 6, and the stir bar 7 to slide downwards and insert into the inner cavity of the beaker, making it easy to pick up and put down the stir bar 7. The operation is simple and convenient. Through the setting of the drive component, the rotating column 4 can drive the cross bar 5, the rotating rod 6, and the stir bar 7 to rotate, thereby allowing stir bars 7 of different materials to rotate to the top of the beaker to stir the solution. This solves the problem that the existing magnetic stirrer 1 cannot replace the magnetic stir bar 7 of different materials according to the different solutions being stirred, resulting in limited flexibility in use.

[0024] In this embodiment, an anti-slip pad 19 is provided at the bottom of the stirrer 1, which can improve the roughness of the bottom of the stirrer 1 and thus prevent it from moving when using the device, thereby improving the stability of the device during use.

[0025] In this embodiment, the drive assembly includes a worm gear 18, a worm 16, and a turntable 17. The worm gear 18 is fixedly sleeved on the outer wall of the rotating column 4. One end of the worm 16 is rotatably connected to the left side of the inner cavity of the frame 15 through a bearing, and the other end of the worm 16 extends to the right end of the frame 15 and is fixedly connected to the knob 10. Rotating the turntable 17 causes the turntable 17 to drive the worm 16 to rotate. Since the worm 16 meshes with the worm gear 18, when the worm 16 rotates, the worm gear 18 can drive the rotating column 4 to rotate, thereby causing the cross 5, the rotating rod 6, and the stir bar 7 to rotate. This allows the stir bar 7 of different materials to rotate above the beaker to stir the solution, solving the problem that the existing magnetic stirrer 1 cannot replace the magnetic stir bar 7 of different materials according to the different solutions being stirred, resulting in limited flexibility in use.

[0026] In this embodiment, the worm 16 meshes with the worm wheel 18, which allows the worm 16 to drive the worm wheel 18 to rotate the rotating column 4 when it rotates. The worm wheel 18 and the worm 16 have a self-locking effect, which prevents the cross 5 from rotating during the stirring process and causing the stir bar 7 to collide with the inner wall of the beaker.

[0027] In this embodiment, multiple anti-slip bars are provided on the outer circumference of the turntable 17.

[0028] In this embodiment, the lifting assembly includes a screw 8, a knob 10, a movable cylinder 9, and a telescopic assembly. The screw 8 is rotatably connected to the middle of the fixed plate 2 via a bearing. The knob 10 is located at the bottom end of the screw 8. The movable cylinder 9 is screwed to the outer wall of the screw 8 and fixedly connected to the bottom end of the top plate 3. The telescopic assembly is located between the top plate 3 and the fixed plate 2. Rotating the knob 10 causes the screw 8 to rotate. Under the action of the rotational force of the screw 8's outer wall thread, when the screw 8 rotates, the movable cylinder 9 can push the top plate 3 to slide up and down, thereby realizing the height adjustment of the stir bar 7. After the beaker is placed on the stirrer 1, the lifting assembly drives the cross 5, the rotating rod 6, and the stir bar 7 to slide downwards and insert into the inner cavity of the beaker, making it convenient to pick up and put down the stir bar 7. The operation is simple and convenient.

[0029] In this embodiment, the telescopic assembly includes a telescopic cylinder 11, a telescopic rod 12, and a connecting assembly. The telescopic cylinder 11 is disposed at the top of the fixed plate 2. The telescopic rod 12 is slidably inserted into the inner cavity of the telescopic cylinder 11. The top end of the telescopic rod 12 is fixedly connected to the bottom end of the top plate 3. The connecting assembly is disposed in the inner cavity of the telescopic cylinder 11 and fixedly connected to the outer wall of the telescopic rod 12. When the top plate 3 slides up and down, the telescopic rod 12 can slide up and down synchronously in the inner cavity of the telescopic cylinder 11. Under the combined action of the telescopic rod 12 and the telescopic cylinder 11, the moving cylinder 9 can be prevented from rotating with the screw 8 when the screw 8 rotates.

[0030] In this embodiment, the connecting component includes a connecting groove 13 and a connecting block 14. The connecting groove 13 is opened on one side of the inner wall of the telescopic cylinder 11. The connecting block 14 is slidably embedded in the inner cavity of the connecting groove 13 and fixedly connected to the outer wall of the telescopic rod 12. Under the combined action of the connecting block 14 and the connecting groove 13, one end of the telescopic rod 12 can always be inserted into the inner cavity of the telescopic cylinder 11.

[0031] In this embodiment, the inner cavity of the connecting groove 13 and the outer wall of the connecting block 14 are adapted to each other and are both dovetail-shaped, so that one end of the connecting block 14 is always inserted into the inner cavity of the connecting groove 13.

[0032] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
