Abstract:In order to solve the problems of unbalanced heat, low heat utilization rate and complicated operation in the process of moxibustion, and to achieve the goal of high-efficient utilization of heat and smoke, a new type of intelligent moxibustion instrument is designed and implemented. The intelligent moxibustion instrument, including combustion system, fumigation system, collection system and control system, can realize automatic collection of smoke and accurate control temperature intelligently and simplified operation process. The thermodynamic model of the fumigation system of the intelligent moxibustion instrument was established based on heat transfer theory, and the thermal field analysis of the fumigation system was conducted by fluent. The results show that the conical runner is the better one of the two structure schemes, and the designed temperature equalization baffle plays an important role in the temperature equalization. Leakage in practical not only has a slight effect on the heating rate, but also has a certain effect on the distribution of temperature field. The design and research results provide a theoretical basis for the clinical application of modern intelligent moxibustion instrument.
