Title:
PORTABLE POTENTIAL-BALANCING CARBON-OXYGEN EXCHANGE-TYPE SPONTANEOUS RESPIRATOR
Document Type and Number:
WIPO Patent Application WO/2019/140719
Kind Code:
A1
Abstract:
A portable potential-balancing carbon-oxygen exchange-type spontaneous respirator, comprising a mask body (1), a filtration apparatus (2), and an oxygen supply apparatus (3). Provided on the mask body (1) are a sealing ring (11), a flexible head mount (13), and a potential balancer (14). Several circular sector filters (21) are stacked in the circumferential direction within a cavity of the filtration apparatus (2). The oxygen supply apparatus (3) comprises a first can body (31) and a second can body (32). A lithium battery (311), a miniature air pump (312), and a reaction can (314) are provided within the first can body (31). Several cooling copper pipes (319) are provided in the circumferential direction on the outer sidewall surface of the first can body (31). A miniature liquid oxygen can (321), an electric pressure relief valve (322), a tensioning spring (323), and an end cover (324) are provided within the second can body (32). One end of the miniature liquid oxygen can (321) is abutted against the end cover (324) via the tensioning spring (323). The portable potential-balancing carbon-oxygen exchange-type spontaneous respirator is structurally reasonable, has the advantages of being structurally simple, convenient to use, compact, lightweight, and convenient to carry, and effectively solves the problem of a conventional respirator being inconvenient to carry and use.
