Description

TECHNICAL FIELD

[0002] In traditional Chinese medicine treatment, people usually take traditional Chinese medicine, which is mainly composed of roots, stems, leaves and fruits of plants. The raw materials need to be processed into finished traditional Chinese medicine through a specific procedure, and the finished traditional Chinese medicine cannot be taken directly. Therefore, traditional Chinese medicine is usually decocted into traditional Chinese medicine decoction before being taken. In traditional Chinese medicine decoction, people usually put traditional Chinese medicine into a ceramic pot and then place it on the fire for a long time. The pot cover needs to be opened frequently for stirring, which is time-consuming and laborious. There are many motor-driven methods for stirring during decoction in the prior art. However, the motor-driven stirring method has the following disadvantages: no matter the speed is fast or slow, if the motor rotates in the same direction all the time, vortex will be generated, which will cause traditional Chinese medicine to overflow, and the stirring effect is poor. If the motor speed is reduced and the vortex phenomenon is solved by forward and reverse rotation, additional control circuit board and other mechanisms need to be set, which will increase the cost. At the same time, due to the existence of steam during the decoction process, the motor and the corresponding control circuit board are easily affected and prone to failure. SUMMARY
