Problems solved by technology

[0003] In the development and testing stage of the oxygen supply system, repeated debugging is required. If natural persons are used for experimental testing, it is not only inconvenient to test, but also endangers life safety at the stage of immature technology, which brings great obstacles to testing.

Abstract

The invention discloses a breathing simulation device for performance testing of an oxygen supply system, which is suitable for the field of aviation personal protection. The device comprises: a control system, a power module, a cylinder structure, and a head mold structure. The control system controls the movement of the cylinder piston according to the sinusoidal law by controlling the rotation of the motor, so that the gas flow rate flowing through the air pipe of the head mold changes according to the sinusoidal law. The device can set the respiratory rate through the LCD touch screen, and change the respiratory tidal volume by adjusting the position of the photoelectric switch. The present invention truly and accurately simulates the changing law of human respiration in the design of an oxygen regulator for an oxygen mask, replaces the role of a human in an experiment, is simple and intuitive, and is convenient to operate, and has certain application value in the process of designing an oxygen supply system.

Description

technical field [0001] The invention belongs to the field of aviation personal protection, and simulates the changing law of human respiration during the design process of an oxygen regulator for an oxygen mask. Background technique [0002] Oxygen supply is an important means to ensure life safety under anaerobic or hypoxic conditions. The research on oxygen supply is of great significance in the field of aviation personal protection. With the development of aviation technology, the environment in which pilots live is getting worse and worse. It is increasingly important to develop high-precision and high-efficiency oxygen supply systems. [0003] In the R&D and testing phase of the oxygen supply system, repeated debugging is required. If natural persons are used to conduct the experimental test, not only is the test inconvenient, but also life safety will be endangered at the immature stage of the technology, which brings great obstacles to the test.
