Abstract

The invention relates to an electronic oxygen regulator with a multifunctional air valve. The electronic oxygen regulator comprises a shell (1), a control circuit (9), a cockpit pressure sensor (10), an exit pressure sensor (8), a lung-type flap (13), a linear motor (11) and an air valve (3). A three-way micro-solenoid valve (2) is arranged between an oxygen inlet (1a) and the air valve (3) and is connected with the control circuit (9), and a normally-open first passage (2a), a normally-open second passage (2b) and a normally-closed third passage (2) are arranged on the three-way micro-solenoid valve (2). By different air passages of the three-way micro-solenoid valve, the air valve and a rapid-decompression valve are combined into the multifunctional air valve, and meanwhile, functions of suffocation prevention and rapid decompression prevention are achieved. In addition, the structure of the electronic oxygen regulator is simplified further, size and weight of the electronic oxygen regulator are reduced, the failure rate thereof is reduced, and maintenance is facilitated.

Description

technical field [0001] The present invention relates to aviation personal protective equipment, more particularly, to an electronic oxygen regulator with a multifunctional air valve. Background technique [0002] At present, mechanical oxygen regulators at home and abroad include an air valve and a rapid decompression valve in structure, which play the roles of anti-suffocation and rapid decompression protection respectively. Electronic oxygen regulators also basically use this form. , the structure of the oxygen regulator is more complicated, and the product volume and weight cannot be further reduced. Therefore, an electronic oxygen regulator with a multi-function air valve was researched and developed, which is based on the cabin pressure sensor and control circuit already possessed by the electronic oxygen regulator itself. The different air passages of the solenoid valve can combine the air valve and the rapid decompression valve into a multi-functional air valve, and ...
