Embodiment 1

[0051] Compared with the traditional oxygen supply method, the oxygen-enriched environment in the entire room is realized through oxygen supply, but the consumption of oxygen and electric energy is huge. If it is necessary to ensure the effectiveness of oxygen delivery and achieve low-energy oxygen supply, it is only necessary to supply oxygen to the mouth and nose area in a specific working and living environment such as a sitting position. This embodiment proposes an oxygen supply device for a dynamic sitting posture breathing area, including a main body 1, which is a hollow cavity structure inside, and an oxygen inlet 1-0 communicating with the inner cavity of the main body 1, and the oxygen inlet of the main body 1 The opposite surface of 1-0 is the oxygen outlet support plate, the oxygen outlet support plate includes the first installation plate 1-1 and the second installation plate 1-2 spliced ​​with each other, and the oxygen outlet support plate is provided with 8 exter...

Embodiment 2

[0058] This embodiment is to verify the effect of Embodiment 1, specifically to carry out a full-scale test on the oxygen supply device of the present invention.

[0059] Carry out a full-scale experiment on the oxygen supply device. The experimental system is divided into an air supply part and an oxygen supply part. The air supply part is composed of a centrifugal fan, a soft connection, and a governor. , gas flow meter and connecting pipe. In order to ensure that the oxygen-enriched flow at the oxygen outlet is even, the oxygen-air is uniformly mixed in the static pressure box before being sent into the oxygen outlet, and the oxygen-enriched flow is passed into the oxygen inlet 1-0 of the device of the present invention through a rubber hose, and It is discharged from each oxygen outlet 2. The air volume of the fan is controlled by the governor, the oxygen flow rate is read through the gas flow meter, and the opening of the valve is changed to control it.

Embodiment 3

[0069] In this embodiment, the schlieren imaging system is used to test the influence of human breathing airflow and thermal plume on the dynamic sitting posture oxygen supply. The experimental system is composed of a camera, a light source, a real person and a concave mirror. The diameter of the concave lens is 406mm, such as Figure 6 As shown, in the exhalation, breath-holding and inhalation states, the oxygen-enriched flow can still cover the breathing area of ​​the human body in a sitting position, and the respiratory airflow and thermal plume have little effect on the oxygen supply effect of the oxygen supply system.

Abstract

The invention discloses a targeted oxygen supply device for a dynamic sitting posture breathing area of a person. The device comprises a main body; the main body is of a hollow cavity structure; an oxygen inlet communicated with an inner cavity of the main body is formed in the main body; an oxygen outlet supporting plate is arranged on the face, opposite to the oxygen inlet, of the main body; the oxygen outlet supporting plate comprises a first mounting plate and a second mounting plate which are spliced with each other; the oxygen outlet supporting plate is outwards provided with at least four oxygen outlets communicated with an inner cavity of the oxygen outlet supporting plate; the oxygen outlets are distributed in a matrix mode; and a matrix is in bilateral symmetry with the splicing line of the first mounting plate and the second mounting plate as a symmetry axis. Through reasonable arrangement of a component structure, on the basis of capturing a human body breathing area in a sitting posture state and on the basis of determining an oxygen supply target area, full-coverage oxygen supply of the breathing area is realized, the accessibility of oxygen supply is improved, and a multi-oxygen-outlet coupling mode is adopted, so that the oxygen concentration distribution of the breathing area is more uniform, the oxygen consumption is saved by 65%, and meanwhile, a non-direct-contact oxygen supply mode can also reduce the influence of wearing the oxygen supply device on the physical and psychological reaction of the person.

Description

technical field [0001] The invention belongs to the field of oxygen supply, relates to an oxygen supply device, in particular to a targeted oxygen supply device for a dynamic sitting breathing area of ​​a person. Background technique [0002] In the room where the air conditioner is running, it is often necessary to keep the doors and windows closed to ensure the effect of the air conditioner; the respiration of the indoor personnel consumes oxygen and releases carbon dioxide; oxygen content drops. Being in a state of hypoxia for a long time will cause discomfort, drowsiness, unresponsiveness, and decreased work efficiency, which will affect people's physical and mental health, especially in offices and other places where people are dense and need enough oxygen to ensure work efficiency. Oxygen preparation mainly consumes electric energy. If the process of oxygen preparation to act on the human body is considered, it is a relatively difficult choice to consider the supply s...
