Embodiment 1

[0039] The appearance of the portable oxygen concentrator in this embodiment is as attached figure 2 , image 3 , Figure 4 , Figure 7 with Figure 8 shown. figure 2 It depicts the back of the box in this embodiment, and the oxygen generator power supply board switch 111 is arranged in the back of the box. The battery cavity cover 108 at the back of the box can be removed, and the lithium battery can also be installed from the back. Loaded into the battery cavity 109. image 3 It depicts the right side of the box body in this embodiment. The horizontal channels on both sides of the right side plate become the air inlet of the outside world, and a group of small round through holes on the lower right side of the middle part of the right side plate are the exhaust air in the box. Outlet, the fan is installed inside the right panel facing the group of small round through holes. Figure 7 The inner surface structure of the right side board is depicted, the fan 117 is fixe...

Embodiment 2

[0047] The internal structure of the oxygen concentrator in this embodiment is basically the same as that of the first embodiment above, except that an oxygen concentration sensor 115 is added to detect the oxygen concentration in the plateau environment and the output oxygen concentration of the oxygen concentrator in real time.

[0048] When the oxygen generator does not output oxygen, the oxygen output pipe is connected with the surrounding atmosphere. At this time, the oxygen concentration sensor 115 can convert the change of the oxygen concentration value of the external ambient air into the change of the electrical signal, and the electrical signal is amplified and After the analog-to-digital conversion, it is sent to the signal identification circuit in the intelligent control system. The single-chip microcomputer in the intelligent control system judges and processes the oxygen concentration value signal output by the signal identification circuit according to the pre-pr...

Embodiment 3

[0052] The internal structure of the oxygen generator in this embodiment is basically the same as that of the first embodiment above, the difference is that a manual gear regulator is added to the power duty ratio adjustment circuit. The single-chip microcomputer in the intelligent control system determines the gear corresponding to the DC control voltage output to the power duty ratio adjustment circuit according to the gear set by the manual gear regulator, and compares it with the lithium rechargeable battery measured by the power duty ratio adjustment circuit. Comparing the actual voltage, calculating the duty ratio of the voltage driving signal, outputting it from the pins of the microcontroller in PWM mode, and converting it into a DC voltage through a low-pass filter, and the power duty ratio adjustment circuit uses the DC voltage control signal sent by the intelligent system to charge lithium The driving voltage of the battery is pulse width modulated, and the output fl...

Abstract

The utility model relates to a portable oxygenerator suitable for a plateau section. A pressure detection device for a breathing end, a real-time detection device for oxygen concentration of the plateau environment, a detection device for oxygen output and an intelligent judge and control circuit are added to the portable oxygenerator suitable for plateau section based on a traditional oxygenerator. A singlechip in the intelligent judge and control circuit judges and processes output signals from the above detection devices in accordance with a piece of beforehand programmed software program and outputs control signals in time, so as to adjust the quantity of the output oxygen flow and form a pulse oxygen supply mode. Simultaneously, the power supply duty ratio of a driving motor of a compressor can be adjusted to adjust quantity of the compressed air flow, thereby further adjusting the quantity of the oxygen output flow. The output control signals can emit sound-light alarms timely. The portable oxygenerator suitable for plateau section supplies oxygen by pulses, thus the loss of oxygen in the inspiration phase and expiration last phase is avoided; and the portable oxygenerator suitable for plateau section increases the quantity of the oxygen supply flow by improving the speed of the driving motor of the compressor, thus the concentration of the output oxygen can remain unchanged at around 91% though the altitude changes.

Description

technical field [0001] The invention relates to an air separation oxygen production technology, in particular to a portable device for preparing oxygen by separating air by means of pressure swing adsorption, which is suitable for the environment in plateau areas. Background technique [0002] my country has a vast territory, with plateaus and high mountains above 3,000 meters above sea level accounting for about one-sixth of the country's total area. The climate in the plateau area is changeable, cold, windy, and thin air. Among them, the thin air, atmospheric pressure and oxygen partial pressure decrease are the main factors that the plateau environment affects the human body. Ethnic minorities who have lived in plateau areas have adapted to the plateau environment. For those who have lived in low altitude areas for many years, when they first arrive at plateau areas above 3,000 meters, due to the decrease in oxygen content in atmospheric pressure, alveolar gas and arteria...
