[0031] Four support legs 5 are installed on the bottom surface of the housing 1. An expansion dock 6 is installed on the bottom surface of the housing 1. A control module is fixed on the expansion dock 6. The control module includes a motor control unit 601, a heating control unit 602, and a weighing transmitter 603.

Among them, the motor control unit 601 is connected to each magnetic stirring unit 3, and can collect and control the speeds of multiple motor bodies 301. The heating control unit 602 can collect and control the temperature of the heating element. The weighing transmitter 603 can collect the data of the weighing measuring strain gauge 7.

[0032] Please refer specifically to Figure 1 、 Figure 2 and Figure 3 , a top plate 8 is provided above the housing 1. The top plate 8 is connected to the housing 1 through screws and nuts. The top plate 8 does not contact the upper surface of the housing 1. A chamber is reserved between the top plate 8 and the upper surface of the housing 1.

[0033] Please refer specifically to Figure 1 、 Figure 2 and Figure 3 , a cable interface 9 is provided on the upper surface of the control panel 2. The model of the cable interface 9 is adapted to the cable socket 4. A control chip is installed inside the control panel 2. The cable socket 4 is electrically connected to each control module in the expansion dock 6. The motor control unit 601 and the weighing transmitter 603 can communicate with the control panel 2 through cables and can supply power to the control panel 2, thereby realizing overall remote operation. The control panel 2 further includes a display screen 201, buttons 202, and control knobs 203 installed on the front surface. A handle is fixed to the side surface of the control panel 2.

[0034] Please refer specifically to Figure 1 、 Figure 2 and Figure 3, a control switch 10 is installed on the side of the outer shell 1. The control switch 10 is electrically connected to each control module on the docking station 6 and can control the power on and off of the entire device. After the control switch 10 is turned on, the control panel 2 can be used to adjust the rotation speed of the motor body 301. The distance from the magnet holder 302 to the inner top wall of the outer shell 1 is greater than the thickness of the magnet block 303. At the same time, it can receive the measured value of the measuring strain gauge 7 and transmit it to the control panel 2 through the weighing transmitter 603.

[0035] Embodiment 2:

[0036] Based on Embodiment 1, when the user needs to heat, a heating element can be installed on the bottom surface of the top plate 8, and a heating control unit 602 is added to the docking station 6 to measure the temperature of the heating element and control this heating element. The heating control unit 602 can communicate with the control panel 2 and be set by the control panel 2. The heating control unit 602 and the heating element can be single, or a heating element and a heating module can be separately equipped for each motor body 301; in addition, if the user does not need weighing, the weighing transmitter 603 on the docking station 6 and the weighing strain gauges at the four corners can be disassembled, so as to meet the needs of users who do not need the weighing mode.

[0037] At the same time, the control panel 2 is electrically connected to the motor control unit 601. The motor control unit 601 can receive control instructions and feedback real-time information. It can be connected to multiple motor bodies 301 at the same time, and number each motor body 301 for convenient asynchronous control. At the same time, the motor control unit 601 can be used as a transfer station to distribute control instructions to other modules.

[0038] When this utility model is in use: Place the magnetic stirrer in the container, then place the container on the platform plate, and then start the motor body 301. The output end of the motor body 301 drives the magnet holder 302 to rotate. The rotation of the magnet holder 302 drives the magnet block 303 to rotate. The rotation of the magnet block 303 drives the magnetic stirrer to rotate, and the magnetic stirrer completes the stirring of the materials in the container.

[0039] When a weighing transmitter 603 is installed on the docking station 6 and measuring strain gauges 7 are installed at the four corners, the measured mass data can be collected by the measuring strain gauges 7 at the weighing transmitter 603 and transmitted to the control panel 2, and displayed on the display screen 201.

[0040] When a heating control unit 602 is installed on the docking station and a heating element is also installed, the temperature of the heating element can be transmitted to the control panel 2 by the heating control unit 602 and displayed on the screen. At the same time, the required heating temperature can also be set through the control panel 2, and the temperature control is carried out by the heating control unit 602. Meanwhile, through the cable connection between the control panel 2 and the housing 1, the remote control of the control panel 2 is realized, so that the magnetic stirrer can control the rotation speed, control the temperature and obtain quality information during the remote control stirring process, solving the problem of the single function of the common magnetic stirrer in the prior art.

[0041] Through the selection of the weighing transmitter 603 on the docking station and the installation and disassembly of the four-corner weighing strain gauges, the selection of the weighing function can be realized; through the installation and disassembly of the heating control unit 602 and the heating element on the docking station, the selection of the heating function can be realized. In addition, the heating control unit 602 and the heating element can be a single overall solution, or independent heating elements and heating control units 602 can be separately equipped for each motor body 301.

[0042] By setting that the motor body 301 can drive the magnet holder 302 to rotate and then drive the magnet block 303 to rotate, at the same time, through the motor control unit 601, it receives control instructions and feedbacks real-time information, and numbers each motor body 301 for convenient asynchronous control. For example, a single motor control unit 601 can control six motor bodies 301. When only four motor bodies 301 are actually needed, the number of enabled channels of the motor control unit 601 can be set to four by software, then the default fifth to sixth channels are invalid. If nine motor bodies 301 are needed, two motor control units 601 can be used. By setting the number and quantity of the first motor body 301 for the motor control unit 601, multiple motor bodies 301 can be controlled. Among them, the first motor control unit 601 defaults to control the first to sixth motor bodies 301, and the second motor control unit 601 is numbered seven. When the number of enabled control channels is three, it can control the seventh to ninth motor bodies 301, and the remaining tenth to twelfth channels are invalid, realizing the situation of different rotation speeds at multiple points and different control methods at stirring points to adapt to different usage scenarios of different customers.

Those skilled in the art of this industry should understand that the present invention is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principle of the present invention.
