[0023] Example 1: This embodiment provides an intelligent rotary mixer based on an Internet of Things (IoT) remote control system, such as... Figure 1 and Figure 2 As shown, the box includes a body 17. The top of the body 17 is a slope 26, which forms a 45-degree angle with the body. A turntable 18 is mounted on the slope 26, and a test tube clamp for securing test tubes is provided on the turntable 18. A transparent cover 19 is positioned above the turntable 18 to prevent liquid from splashing out of the test tubes placed on it. The transparent cover 19 is hinged to one end of the slope 26 via a pivot, allowing it to be manually rotated and opened. The transparent cover 19 is made of fully transparent PVC material, while the body 17 is composed of 6mm thick wooden logs, providing some protection for the interior.

[0024] By using a transparent cover 19, the experimenter can clearly see the operation of the turntable inside the transparent cover, and it is convenient to observe the experimental results. At the same time, it effectively isolates the experimental part from the outside world, effectively avoiding the danger of test tubes slipping out of the test tube clamp or liquid splashing due to the test tube cap not being tightened.

[0025] like Figure 3 As shown, the box 17 has three layers of baffles 25 fixedly connected to the inner wall of the box 17 via slide rails. The first layer of baffles 25, from bottom to top, is used to place the rechargeable power supply 13, which is a 12V rechargeable power supply. The second layer of baffles 25 is used to place the circuit board. The third layer of baffles 25 is used to place the motor drive module 2 and the motor 12 that control the rotation of the turntable 18. Each layer of baffles 25 is connected to the inner wall of the box 17 via slide rails, so that each layer of baffles can be easily inserted and removed, which facilitates the maintenance and repair of the internal components in the future.

[0026] The circuit board includes a substrate, circuit layers printed on the substrate, and a microcontroller 1, a motor drive module 2, a DC-DC step-down module 14, a communication module 9, a smoke alarm 10, a drive circuit 27, and a button drive circuit 28 soldered on the substrate.

[0028] The charging port 23 is connected to the rechargeable power supply 13 to charge the rechargeable power supply 13. The charging port 23 adopts a DC round hole and is directly connected to a 5V2A fast charger, which saves a lot of charging time compared to the ordinary 5V1A slow charger.

[0029] like Figure 2As shown, a safety door is provided on the rear side of the box body 17. A pull ring 22 is installed on the safety door. One side of the safety door is fixedly connected to the box body 17 by a hinge 24. There are at least five hinges 24, and glue is applied to the hinges 24 to make the connection more secure.

[0037] The microcontroller 1 is connected to the rotary encoder 6 to set the speed of the motor 12 and the working time of the motor 12 through the rotary encoder 6.
