[0018] As shown in Figures 1-10, this embodiment provides a chemical experiment protection device with stirring and heating function, including a base plate 1, a support rod 10, a support frame 2, a swing mechanism 3, a stirring mechanism 4, and a filtering mechanism 5. The base plate 1 is provided with a support rod 10 and a U-shaped support frame 2 at the upper end, and the support frame 2 is located on the left side of the support rod 10. The swing mechanism 3 is provided on both sides of the support frame 2. The upper end of the support frame 2 is provided with a stirring mechanism 4 that is linked with the swing mechanism 3. The stirring mechanism 4 is used to support multiple conical flasks, and the swing mechanism 3 can drive the support frame 2 and the stirring mechanism 4 to swing.

[0019] The stirring mechanism 4 includes an electric heating rotating rod 40, a circular through groove 41, a drive unit 42, a heating stirring rod 43, an electric heating sleeve 44, an extension stirring rod 45, and a stirring plate 46. The electric heating rotating rods 40 are evenly distributed and connected to the filter mechanism 5. The upper end of the support frame 2 is evenly provided with circular through grooves 41 corresponding to the electric heating rotating rods 40. The circular through grooves 41 are provided with a drive unit 42 for supporting the conical flask and driving it to rotate.

[0020] The heating stirring rod 43 has an L-shaped structure with an increasing tilt angle. When the heating rotating rod 40 is driven by an external force to rotate the heating stirring rod 43, the heating stirring rod 43 with different tilt angles can achieve a better stirring effect. The outer surface of the heating rotating rod 40 is also evenly provided with heating sleeves 44 that are distributed vertically and located below the heating stirring rod 43. The heating sleeves 44 on the upper and lower sides are staggered. The lower heating sleeve 44 is made of a material that can be magnetically attracted. The lower heating sleeve 44 can be magnetically attracted to the driving unit 42.

[0021] An extension stirring rod 45 is slidably provided at the end of the heating sleeve 44 away from the heating rotor 40. A stirring plate 46 is also provided at the upper end of the extension stirring rod 45, located on the outer side of the corresponding heating sleeve 44. Under the action of centrifugal force generated during the rotation of the heating rotor, the extension stirring rod 45 can drive the stirring plate 46 to move away from the heating sleeve, thereby further improving the stirring effect on the bottom of the conical flask. In addition, in order to prevent the components in the chemical liquid from corroding the heating rotor 40, heating stirring rod 43, heating sleeve 44, extension stirring rod 45 and stirring plate 46, an anti-corrosion coating can be provided on the surface of the heating rotor 40, heating stirring rod 43, heating sleeve 44, extension stirring rod 45 and stirring plate 46.
