The invention discloses a semi-closed underwater circulation respirator which comprises a back frame, a breathing circulation system and an air supply system. Wherein the breathing circulation system comprises a mouthpiece valve, an expiration pipe, an expiration bag, an automatic exhaust valve, a carbon dioxide adsorbent tank, an inspiration bag and an inspiration pipe; the gas supply system comprises an oxygen bottle, an oxygen pressure reducing valve, a nitrogen-oxygen mixed gas bottle, a nitrogen-oxygen mixed gas pressure reducing valve, a gas path switching valve and a gas supply pipeline; oxygen serves as an air source to be used at the shallow depth of 7 meters, nitrogen-oxygen-nitrogen-oxygen mixed gas is used for diving at the depth of 7 meters to 40 meters, the nitrogen-oxygen mixed gas becomes clean gas again after being subjected to oxygen dioxide absorption through the absorbent tank, the clean gas enters the lung bag again and then enters the inspiration pipeline to be supplied to a human body for breathing, the oxygen utilization rate is increased, the size is small, and cost is low. The weight is light, the floating pressure reduction time after large-depth diving is effectively shortened, and the whole diving process is safer.

    本发明公开了一种半闭式水下循环呼吸器,包括背架、呼吸循环系统和供气系统;其中,所述呼吸循环系统包括咬嘴阀、呼气管、呼气袋、自动排气阀、二氧化碳吸附剂罐、吸气袋、吸气管;所述供气系统包括氧气瓶、氧气减压阀、氮氧混合气瓶、氮氧混合气减压阀、气路切换阀和供气管路;本发明利用氧气作为气源在7米以浅的深度进行使用,在7米至40米使用氮氧氮氧混合气进行潜水,氮氧混合气体经过吸收剂罐吸收掉二氧化后重新成为洁净的气体,重新进入肺袋后再次进入吸气管路供人体呼吸,提高了氧气利用率,体积小,重量轻,有效的减少大深度潜水后,上浮的减压时间,使整个潜水过程更加安全。
