[0024] In the embodiment, the motor 9 is started to drive the rotary rod A 10 to rotate, the gear A 12 on the rotary rod A 10 is engaged with the gear B 13 on the rotary rod B 11, so that the rotary rod B 11 rotates, and the stirring blade 14 on the surface of the rotary rod B 11 can stir the chemicals in the jar body 2, so that the chemicals can be heated more uniformly during the distillation process, and the distillation rate of the chemicals is improved. Since one end of the spring A 18 is fixedly connected with the side surface of the telescopic link 16, and the scraping surface of the scraper 17 is attached to the inner wall of the jar body 2, when the rotary rod A 10 rotates, the scraper 17 can remove the substances that may be attached to the inner wall of the jar body 2, preventing impurities from accumulating on the inner wall of the jar body 2, ensuring the purity of the distillation process, and improving the heat transfer efficiency of the jar body 2.
