Novel enhanced sealing structure of oval cleaning tank for oxygen respirator

The utility model relates to the technical field of lifesaving equipment, in particular to a novel reinforced sealing structure of an oval cleaning tank for an oxygen respirator, which comprises a cover plate and an oval cleaning tank shell. The elliptical cleaning tank shell is connected with the cover plate; a limiting ring is arranged outside the elliptical cleaning tank shell; a sealing ring is arranged between the elliptical cleaning tank shell and the cover plate; a partition plate is embedded in the cover plate. By the adoption of the scheme, the utilization rate of the carbon dioxide absorbent in the cleaning tank can be increased, the thickness of the oxygen respirator is reduced, meanwhile, the sealing performance of the cleaning tank is improved, and the safety of the cleaning tank is improved. 本实用新型涉及救生设备技术领域，尤其是氧气呼吸器用椭圆形清净罐新型增强密封结构，包括盖板和清净罐外壳，所述清净罐外壳为椭圆形清净罐外壳；所述椭圆形清净罐外壳和所述盖板连接；所述椭圆形清净罐外壳外设有限位圈；所述椭圆形清净罐外壳和所述盖板间设有密封圈；所述盖板内嵌设有隔板。采用本方案，能够增强清净罐内二氧化碳吸收剂的利用率，减小氧气呼吸器的厚度，同时提升清净罐的密封性，增强清净罐的安全性。
