Description

Technical Field

[0001] This utility model relates to the field of magnetic stirrers, and more particularly to a heat-collecting constant-temperature heating magnetic stirrer. Background Technology

[0002] A magnetic stirrer is a device that uses magnetic force as a power source to mix liquids. It typically consists of a motor, a magnetic stirring rod, and an external magnetic stirrer. Magnetic stirrers are suitable for use in experiments or production processes in fields such as laboratories, pharmaceuticals, biotechnology, and chemicals where solution mixing or suspension of solids is required.

[0003] To facilitate solution mixing and stirring, a heat-collecting, constant-temperature magnetic stirrer is needed. For example, Chinese Patent Publication No. CN210097557U discloses a heat-collecting, constant-temperature magnetic stirrer, including a housing. The top outer wall of the housing has a heat insulation layer, and a heating cup is mounted on the top outer wall of the heat insulation layer. A stirring container is located inside the heating cup. A fixing rod is fixedly installed on one side of the top outer wall of the housing. A sliding connecting block is provided on the outer wall of the fixing rod, and a crossbar is provided on one side of the sliding connecting block. A snap-fit ​​plate is fixedly installed at the end of the crossbar near the heating cup, and an arc-shaped groove is formed on one side of the outer wall of the snap-fit ​​plate. This invention allows operators to easily control the heating temperature of the stirring liquid in the stirring container, ensures uniform heating of the stirring liquid, improves the stability of the stirring liquid in the constant-temperature magnetic stirrer, facilitates temperature adjustment of the stirring liquid in the stirring container, facilitates control of the drive motor speed, prevents accidental burns from touching the outer wall of the heating cup, and is adaptable to stirring containers of different sizes.

[0004] Some magnetic stirrers use a heating element to heat the mixing container and maintain a constant temperature. However, in actual operation, considering that the liquid needs to be stirred by rotating the stirring rotor inside the mixing container, such magnetic stirrers do not have a fixing device inside the heated container. This may cause the stirring rotor to rotate too fast, resulting in the mixing container shaking or even tilting. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies where the lack of fixing measures may cause the stirring container to shake or even tilt, and to propose a heat-collecting constant-temperature heating magnetic stirrer.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] Design a heat-collecting constant temperature magnetic stirrer, including a base, a heating container and a temperature probe are fixedly installed on the top of the base, and a control unit is provided on its side. A heating element electrically connected to the control unit is fixedly installed on the inner wall of the heating container, and the stirring container can be placed inside the heating container.

[0008] The base is located on the side of the heating container and is equipped with a clamping component via an adjustment assembly. The adjustment assembly is used to adjust the clamping component to fix the stirring container of different sizes.

[0009] Furthermore, the adjustment component includes a fixed base, which is fixedly installed on the side of the heating container. A movable bracket is slidably connected inside the fixed base. A locking member is slidably connected to the bottom of the movable bracket through a sliding groove. One side of the locking member is provided with an unlocking part and a locking part, and the other side is fixedly connected to the inner side of the sliding groove with a first spring.

[0010] Furthermore, the side of the fixed base is provided with several slots, and both the unlocking part and the locking part are slidably connected to the side of the movable bracket, and the locking part can be locked into the slots.

[0011] Furthermore, the top of the movable bracket is rotatably connected to a drive gear via a mounting slot, and a pair of connecting rods are slidably connected inside it. The pair of connecting rods are arranged opposite each other, and a rack is fixedly installed between their opposing sides. The pair of racks mesh and rotate with the two sides of the drive gear respectively. A second spring is fixedly connected between the pair of connecting rods and the side of the mounting slot.

[0012] Furthermore, the drive gear is rotatably connected to the mounting groove via a rotating shaft. One end of the rotating shaft extends to the periphery of the movable bracket and is fixedly mounted with a handwheel. A torsion spring is sleeved around the handwheel, and the two ends of the torsion spring are fixedly connected to the sides of the movable bracket and the handwheel, respectively.

[0013] Furthermore, the clamping member includes a pair of clamping blocks, an arc-shaped groove is formed between the opposing sides of the pair of clamping blocks, and one end of each is fixedly connected to a pair of connecting rods. The clamping blocks can clamp the stirring container through the arc-shaped groove.

[0014] The present invention proposes a heat-collecting constant-temperature heating magnetic stirrer, which has the following advantages: the present invention can fix the stirring container with a pair of clamps, which effectively prevents the stirring container from tilting or shaking due to excessive stirring rotor speed. Furthermore, the height and width of the clamping parts can be adjusted by the adjustment component, which is convenient to adapt to heating containers of different widths and heights. The structure is simple and highly practical. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Reference Figure 1-4 A heat-collecting constant-temperature magnetic stirrer includes a base 1, a heating container 2 and a temperature probe 3 are fixedly installed on the top of the base 1, and a control unit 4 is provided on its side. A heating element 5 electrically connected to the control unit 4 is fixedly installed on the inner wall of the heating container 2, and a stirring container 6 can be placed inside it.

[0022] The base 1 is located on the side of the heating container 2 and is equipped with a clamping member 8 via an adjustment component 7. The adjustment component 7 is used to adjust the clamping member 8 to fix the stirring container 6 of different sizes.

[0023] It should be added that the base 1 is equipped with a motor, the shaft end of the motor is equipped with a pair of magnets, the stirring container 6 is equipped with a stirring rotor, the stirring rotor is located between the pair of magnets and is affected by the magnetic field of the magnets, the motor is electrically connected to the control unit 4, and the stirring rotor is driven to rotate by the motor in conjunction with the magnets to stir the liquid.

[0024] Furthermore, the adjustment component 7 includes a fixed base 71, which is fixedly installed on the side of the heating container 2. A movable bracket 72 is slidably connected inside the fixed base 71. A locking member 74 is slidably connected to the bottom of the movable bracket 72 through a sliding groove 73. One side of the locking member 74 is provided with an unlocking part 741 and a locking part 742, and a first spring 75 is fixedly connected between its other side and the inner side of the sliding groove 73.

[0025] Furthermore, the side of the fixed base 71 is provided with several slots 76, and the unlocking part 741 and the locking part 742 are slidably connected to the side of the movable bracket 72, and the locking part 742 can be locked into the slot 76.

[0026] Specifically, under normal circumstances, the locking member 74, under the action of the first spring 75, causes the locking part 742 to be inserted into the slot 76, thereby fixing the movable bracket 72.

[0027] Pressing the unlocking part 741 can cause the locking member 74 to move the locking part 742. When the locking part 742 disengages from the slot 76, the movable bracket 72 can be adjusted.

[0028] It should be noted that when the locking part 742 is inserted into the bottommost slot 76, the unlocking part 741 will not abut against the fixed base 71, thus avoiding jamming the unlocking part 741. The function of adjusting the movable bracket 72 to move the clamping member 8 facilitates clamping the stirring container 6 at different heights.

[0029] More specifically, the top of the movable bracket 72 is rotatably connected to a drive gear 78 via a mounting groove 77, and a pair of connecting rods 79 are slidably connected inside it. The pair of connecting rods 79 are arranged opposite each other, and a rack 791 is fixedly installed between their opposing sides. The pair of racks 791 mesh with the two sides of the drive gear 78 respectively and rotate. A second spring 792 is fixedly connected between the pair of connecting rods 79 and the side of the mounting groove 77.

[0030] In general, the drive gear 78 is rotatably connected in the mounting groove 77 via a rotating shaft 771. One end of the rotating shaft 771 extends to the periphery of the movable bracket 72 and is fixedly mounted with a handwheel 772. A torsion spring 773 is sleeved around the handwheel 772. The two ends of the torsion spring 773 are fixedly connected to the sides of the movable bracket 72 and the handwheel 772, respectively.

[0031] Specifically, the pair of connecting rods 79 are fixed to the stirring container 6 by the clamping member 8 under the action of the second spring 792;

[0032] It is worth mentioning that because the torsion spring 773 fixes the drive gear 78, the drive gear 78 constrains the rack 791, and consequently, the pair of connecting rods 79 will not move arbitrarily. Specifically, by rotating the shaft 771 through the handwheel 772, the drive gear 78 drives the pair of connecting rods 79 to move away from each other. After releasing the handwheel 772, the pair of connecting rods 79 clamp the stirring container 6 under the action of the second spring 792, thus achieving the function of adapting to stirring containers 6 of different diameters.

[0033] Finally, the clamping member 8 includes a pair of clamping blocks 81. An arc-shaped groove 82 is provided between the opposing sides of the pair of clamping blocks 81, and one end of each is fixedly connected to a pair of connecting rods 79. The clamping blocks 81 can clamp the stirring container 6 through the arc-shaped groove 82.

[0034] Working method: During operation, the stirring container 6 is placed inside the heating container 2, and then the temperature probe 3 and the stirring rotor are placed inside the stirring container 6. The temperature and speed are adjusted by the control unit 4.

[0035] Then, after placing the mixing container 6, press the unlocking part 741 to move the locking part 74 and the locking part 742, which makes it easier to adjust the height of the movable support 72. Then, under the support of the first spring 75, the locking part 742 engages with the slot 76 to fix the movable support 72.

[0036] Finally, by rotating the shaft 771 through the handwheel 772, the drive gear 78 drives a pair of connecting rods 79 to move away from each other. After releasing the handwheel 772, the pair of connecting rods 79 clamp the stirring container 6 under the action of the second spring 792, thus achieving the function of adapting to stirring containers 6 of different diameters.

[0037] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
