Multistage-oxygen-pressurizing portable oxygen station driven by motor

Abstract

The invention discloses a multistage-oxygen-pressurizing portable oxygen station driven by a motor. The portable oxygen station comprises an oxygen generating device and a pressurizing device, the oxygen generating device comprises a display controller and an oxygen concentration detector, and the pressurizing device comprises a pressurizing gas incoming pipe, a pressurizing cylinder, a pressurizing gas outgoing pipe, a first pressure sensor, a second pressure sensor, a controller, a motor driver, a motor, a transmission shaft and a cam. By effectively integrating the oxygen generating deviceand the pressurizing device, the whole portable oxygen station has both oxygen generating and pressurizing functions and meets needs on application in outdoor complex environments; the pressurizing cylinder is driven by the motor to compress oxygen to generate high pressure to finally enable the oxygen to reach needed output pressure, so that the portable oxygen station has the advantages of beinghigh in oxygen output pressure, accurate and stable in oxygen output pressure, needless of an external power gas source, capable of lowering system power consumption and reducing noise and supportiveof oilless driving, and is high in integration level, small in size and light in weight.

Description

Technical field [0001] The invention relates to an oxygen station with both oxygen production and pressurization functions, in particular to a portable oxygen station based on a motor-driven multi-stage oxygen pressurization. Background technique [0002] Oxygen production equipment is mainly used in homes, hospitals, etc., to provide an independent source of oxygen supply for personal breathing. Traditional oxygen production products only have the oxygen production function, but do not have the oxygen pressurization function. It is not easy to refill for outdoor use. It can only output low-pressure oxygen. It is suitable for indoor operation, suitable for normal temperature working environment, and cannot meet the complex outdoor environment application; , The traditional oxygen production equipment has no oxygen concentration detection and display function, no oxygen concentration adjustment function, and the output oxygen concentration is low, the flow rate is small, and the e...

Problems solved by technology

[0005] Using a gas booster pump to pressurize oxygen is a conventional oxygen booster method, which has the problems of high power, high noise, large volume, low output pressure accuracy, and poor stability. This is because: the pneumatic booster method requires The air power source with large displacement is provided separately. Generally, a high-power air compressor is used as the input drive source to push the piston to move, so the system is large and heavy; When the end pressure is equal, the maximum pressure is reached, and the output air pressure is stable. At this time, the accuracy and stability of the output gas pressure are easily affected by the air pressure at both ends of the piston, resulting in continuous pressure fluctuations, and it is impossible to output gas with high precision and stability.
