The performance of the mechanical alarm,as one of the key components of the respiration apparatus,plays a very important role to the working performance of the whole respiration apparatus,so it is necessary to carry out deep study on it. In this paper,based on the study of the alarm structure, the factors that influence the main parameters of the alarm were found out, theoretical analysis was made on the influence variation relation,and its correctness was verified experimentally.% 报警器作为呼吸器的关键部件之一，其性能好坏对整个呼吸器工作性能至关重要，有必要对其进行深入研究。在对报警器结构进行研究的基础上，找出影响报警器主要性能参数的因素，理论分析了其影响变化关系，并通过实验验证了理论分析的正确性。
