The invention relates to the technical field of respirators, in particular to a double-closed-loop circulation respirator which comprises a mouthpiece with a one-key breathing loop switching function, a machine A, a machine B and an air supply module with a one-way valve function, the internal structures of the machine A and the machine B are the same, and the machine A and the machine B are connected through a connecting mechanism. The upper end of the machine A and the upper end of the machine B are both communicated with the mouthpiece through hose assemblies used for expiration and inspiration, and the air supply module is communicated with the machine A and the machine B; through cooperation of the air supply module, the hose assembly, the mouthpiece and the connecting mechanism, the machine A and the machine B are linked, the underwater working time can be greatly prolonged through double-machine linkage, and meanwhile, double guarantees are provided, that is, when water enters one machine or a fault occurs, the machine can be rapidly switched to the other machine to work; and compared with single-machine diving, the number of carried gas cylinders can be reduced, and the underwater work intensity of the diver is relieved.
本发明涉及呼吸器技术领域,特别涉及双闭路循环呼吸器,包括带有一键切换呼吸回路功能的咬嘴、内部结构呈相同设置的A机器和B机器以及自带单向阀功能的供气模块,所述A机器与B机器之间通过连接机构连接,所述A机器与B机器的上端均通过用于呼气和吸气的软管组件与咬嘴连通,所述供气模块分别与A机器和B机器连通;本发明通过供气模块、软管组件、咬嘴和连接机构的配合,将A机器与B机器进行联动,双机联动可极大增加水下工作时长,同时提供双重保障,即一台机器进水或故障时可迅速切换至另一台机器工作;对比单机器潜水,还可减少携带气瓶的数量,减轻潜水员水下工作的强度。
