Description

Technical Field

[0001] This invention belongs to the field of high-altitude oxygen-enriched environment design technology, specifically relating to an attached diffused oxygen supply device and method for high-altitude areas. Background Technology

[0002] The unique low-pressure and hypoxic environment at high altitudes can easily cause symptoms such as decreased physical strength, dizziness, and nausea in people from other regions, including those on missions or business trips. In particular, when people are sleeping, it is necessary to provide them with a suitable oxygen-rich environment to meet their sleep requirements.

[0003] Oxygen enrichment is a common method in high-altitude, hypoxic environments. Creating an oxygen-rich environment for sleep can significantly reduce altitude sickness and sleep difficulties, thus effectively improving sleep quality. Currently, diffused oxygen supply throughout and in specific spaces is a common method for indoor oxygen enrichment in high-altitude buildings. While whole-space oxygen supply can diffuse oxygen from the air supply terminals to the entire indoor space, its supply rate is slow, and uneven oxygen concentration distribution is difficult to avoid, leading to low enrichment efficiency and energy waste. Summary of the Invention

The present invention has a simple structure, low energy consumption, and can quickly and efficiently increase the oxygen concentration in the space.

[0005] This invention is achieved through the following technical solution:

[0006] An attached diffused oxygen supply device for use in high-altitude areas includes an oxygen generating device and a diffused oxygen supply device, wherein the oxygen generating device and the diffused oxygen supply device are connected by an oxygen supply pipeline.

[0007] The diffused oxygen supply device is installed on the wall near the upper side of the rest area and close to the breathing area. An air outlet is provided on the side of the diffused oxygen supply device near the breathing area, and one side of the air outlet is connected to the wall.

[0008] Furthermore, the air outlet has a slot-type structure.

[0016] A method for attaching diffused oxygen supply to a bedroom in high-altitude areas includes the following steps:

[0017] When the oxygen generator is turned on, oxygen flows through the oxygen supply pipeline to the air outlet of the diffusion oxygen supply device to form a jet.

[0018] After being delivered from the air outlet, the jet moves forward along the vertical wall surface. The main body of the jet then flows vertically downward along the wall surface. After passing through the breathing zone of the human head, it hits the ground and turns into a horizontal diffusion flow, completing the indoor oxygen diffusion supply.

[0036] The present invention will be further described in detail below with reference to specific embodiments. These descriptions are for explanation purposes only and are not intended to limit the scope of the invention.

[0037] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present invention.

[0038] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this invention are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of the invention described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover a non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0039] This invention provides an attached diffused oxygen supply device for use in high-altitude areas, such as... Figure 1 and Figure 2 As shown, it includes an oxygen generating device 1 and a diffused oxygen supply device 3, which are connected by an oxygen supply pipeline 2.

[0040] The diffused oxygen supply device 3 is installed on the wall near the upper side of the rest area and near the breathing area. The diffused oxygen supply device 3 has an air outlet on the side near the breathing area, and one side of the air outlet is connected to the wall.

[0041] Preferably, the air outlet has a slotted structure, which facilitates the directional and quantitative adhesion of oxygen to the vertical wall surface, forming a "Coanda effect," i.e., a diffuse jet pattern. Specifically, it should be noted that: High-altitude areas have high elevations; studies show that for every 100m increase in altitude, the air temperature decreases by 0.6℃. Therefore, high-altitude areas are characterized by consistently low temperatures, requiring heating of the building interior for extended periods. In summer, due to strong solar radiation on the plateau, buildings generate significant heat, sometimes necessitating cooling and ventilation. Thus, buildings in high-altitude areas require year-round ventilation. Existing diffuse oxygen supply methods allow oxygen to diffuse freely throughout the room or reach the breathing zone directly at a certain speed, achieving precise oxygen supply. However, both of these methods are affected by the airflow from indoor heating / cooling ventilation, which reduces their oxygen supply efficiency. In contrast, the attached air supply oxygen supply method of this application, because the airflow dominates the oxygen flow path, can precisely supply oxygen to people based entirely on the flow paths of hot and cold air, thus achieving precise oxygen supply to the breathing zone even under indoor heating / cooling conditions.

[0042] Meanwhile, because high-concentration oxygen is denser than air, it tends to sink in the air. Compared to existing diffusion pillows, which require delivering oxygen to the breathing area and thus necessitate a certain amount of momentum, potentially causing a draft sensation on the head and neck, leading to discomfort with prolonged use, nasal oxygen supply products directly contact the nasal mucosa. In high-altitude environments, the mucosa is more sensitive and fragile, exacerbating discomfort with this method. Furthermore, nasal oxygen supply products restrict user movement, potentially reducing sleep quality under certain conditions. In contrast to diffusion pillows and nasal oxygen supply products, the oxygen delivery method used in this application, which involves adhering to walls and impacting the ground before diffusing along the ground, forms an air lake. The oxygen gradually diffuses upwards, and its speed decreases rapidly upon impact with the ground. When it reaches the area where people are active, the wind speed is low and will not cause discomfort. It should be noted that the diffused oxygen supply in this application increases the oxygen content of a local space, creating an oxygen-rich environment for the human body, thereby alleviating symptoms of hypoxia. In most cases, the user's activity area is in the lower part of the room, while the upper part is unused and ineffective space, requiring no adjustment of oxygen concentration. The attached oxygen supply in this application, however, is a bottom-up delivery method, designed to ensure the oxygen concentration in the area where people are active. Under the same oxygen flow rate, attached oxygen supply allows the oxygen concentration in the area to reach the required standard more quickly.

[0043] Preferred, such as Figure 4 As shown, the diffused oxygen supply device 3 is a single device with a second air outlet 4 on both sides. It is more suitable for rest areas with two people or two rest areas set up alternately. Oxygen flows out from the second air outlet 4 on both sides of the diffused oxygen supply device 3, which facilitates targeted, efficient and rapid oxygen supply to users in the rest area.

[0044] Furthermore, the aspect ratio of the second air outlet 4 is 20:1, and those skilled in the art can set it to a size of 200mm*10mm. The distance between the second air outlet 4 and the human head breathing area is less than or equal to 800mm.

[0045] Preferred, such as Figure 5 As shown, the diffused oxygen supply device 3 is a single unit, with a first air outlet 5 at its bottom. It is more suitable for single-person rest areas. Oxygen flows out from the first air outlet 5 at the bottom of the diffused oxygen supply device 3, which facilitates targeted, efficient and rapid oxygen supply to the breathing area of ​​the user in the rest area.

[0046] Furthermore, the aspect ratio of the first air outlet 5 is 30:1, and those skilled in the art can set it to a size of 300mm*10mm. The distance between the first air outlet 5 and the human head breathing area is less than or equal to 750mm.

[0047] Specifically, such as Figure 7 As shown, using the side-attachment method of the second air outlet 4 in this application, compared with the grille-type oxygen supply outlet, when the oxygen supply concentration is 90%, after 600 seconds of oxygen supply, the oxygen supply efficiency of the side-attachment method in this application is 2.21% higher than that of the global diffusion oxygen supply method; when the oxygen supply concentration is 28.68%, after 600 seconds of oxygen supply, the oxygen supply efficiency of the first air outlet 5 in this application is 14.84% higher than that of the global diffusion oxygen supply method.

[0048] like Figure 8 As shown, by comparing the oxygen supply efficiency of the first air outlet 5 with the global diffusion oxygen supply in the sleep breathing area under different oxygen supply concentrations, when the oxygen supply concentration is 90%, the oxygen supply efficiency of the lower attachment method is 2.47% higher than that of the global diffusion oxygen supply method after 600 seconds of oxygen supply; when the oxygen supply concentration is 26.68%, the oxygen supply efficiency of the lower attachment method is 17.81% higher than that of the global diffusion oxygen supply method after 600 seconds of oxygen supply.

[0049] Preferred, such as Figure 3 As shown, the diffused oxygen supply device 3 is a single unit, with a first air outlet 5 at its bottom and second air outlets 4 on both sides. It is more suitable for single multi-person rest areas and can cover more rest areas.

[0050] Preferred, such as Figure 6 As shown, there are multiple diffusion oxygen supply devices 3, each with a first air outlet 5 at its bottom. This is more suitable for bedrooms with multiple rest areas. The number of diffusion oxygen supply devices 3 can be set according to the number of rest areas, so that oxygen can be directly and quickly supplied to the rest areas.

[0051] Preferably, the oxygen generating device 1 includes a molecular sieve oxygen generator. The output end of the molecular sieve oxygen generator is equipped with a fan and a humidification bottle. The fan is used to provide power for the oxygen to form a jet and to form a diffuse jet after impacting the wall. The humidification bottle is used to provide a certain humidity for the oxygen to prevent the air from being too dry and causing discomfort to the user.

[0052] Preferably, an adjustable switch 6 is provided on the oxygen supply pipe 2 at the input or output end of the diffusion oxygen supply device 3, so that the user can control the oxygen flow rate according to his or her own needs. The adjustable switch 6 can be an electromagnetic valve to reduce or increase the volume that can pass through the oxygen supply pipe 2 per unit time.

[0053] This invention provides an attached diffusion oxygen supply method for use in high-altitude areas, comprising the following steps:

[0054] When the oxygen generator 1 is turned on, oxygen flows through the oxygen supply pipe 2 to the air outlet of the diffusion oxygen supply device 3 to form a jet.

[0055] After being delivered from the air outlet, the jet moves forward along the vertical wall surface. The main body of the jet then flows vertically downward along the wall surface. After passing through the breathing zone of the human head, it hits the ground and turns into a horizontal diffusion flow, completing the indoor oxygen diffusion supply.

[0056] Example 1: Oxygen supply device 3 using the second air outlet 4;

[0057] 1. The oxygen mass fraction at the oxygen outlet is 90% --- flow rate is 5L / min --- velocity is 0.5m / s;

[0058] like Figure 9 As shown, this embodiment uses a 7.5m × 3.7m × 3m (L × W × H) sleeping space in a plateau region as the research object. Two beds are distributed within the space, each measuring 2m × 1.2 × 0.2m (L × W × H). A human dummy is placed on each bed. A diffusion oxygen supply device 3 is installed 0.75m away from the head of the bed in the sleeping breathing area. The oxygen flow rate of the diffusion oxygen supply device 3 is 10L / min. Second air outlets 4, each 200*10mm in size, are located on both sides of the device. The flow rate of the oxygen supply from each outlet 4 is 5L / min, and the oxygen mass fraction at the corresponding outlet is 90%. In this embodiment, the average oxygen concentration in the sleeping breathing area is compared under side-attachment and global diffusion methods. The initial oxygen volume fraction in the sleeping room is 20.95%, calculated using the formula:

[0059]

[0060] That is: O2 (mass fraction) - O2 (volume fraction) = 0.2326 - 0.2095 ≈ 2%, so the initial oxygen mass fraction in the sleeping room is 22.95%, and the oxygen mass fraction at the second air outlet 4 and the grille-type oxygen supply outlet is 90%. The average oxygen concentration in the sleeping breathing zone can be calculated through numerical simulation. Figure 10 As shown, the oxygen concentration in the sleep breathing area under the side-attachment method of the second air outlet 4 is significantly higher than the average oxygen concentration in the sleep breathing area under the global diffusion method, and the effect becomes more obvious over time. After 600 seconds of oxygen supply, the oxygen concentration in the sleep breathing area under the side-attachment method is 1.48% higher than the average oxygen concentration in the sleep breathing area under the global diffusion method. In addition, the oxygen supply efficiency ε, which represents the ability of oxygen to be delivered from the oxygen outlet to the target breathing area, is used to evaluate the local oxygen environment creation capability of the oxygen supply method. The calculation formula is as follows:

[0061]

[0062] C represents the average oxygen concentration in the target breathing zone. s The value ε represents the oxygen supply concentration at the oxygen outlet, and C0 represents the initial oxygen concentration in the hypoxic room. The closer the ε value is to 1, the closer the oxygen concentration in the target breathing zone is to the oxygen supply concentration at the oxygen outlet, and the higher the oxygen supply efficiency.

[0063] Therefore, the oxygen supply efficiency of each oxygen supply method under Example 1 can be calculated. After 600 seconds of oxygen supply, the oxygen supply efficiency of the side-attach method is: The oxygen supply efficiency under global diffusion mode is It can be seen that after 600 seconds of oxygen supply, the oxygen supply efficiency of the side-attached method of the second air outlet 4 is 2.21% higher than that of the global diffusion method.

[0064] 2. Oxygen mass fraction at the oxygen outlet is 28.68% --- flow rate is 5L / min --- velocity is 0.5m / s

[0065] In this embodiment, the initial oxygen mass fraction in the sleeping room and the oxygen flow rate of the diffused oxygen supply device 3 are the same as in Embodiment 1; let the volume fraction of the slotted oxygen supply outlet and the grille oxygen supply outlet be x, calculated by the following formula:

[0066] The oxygen at the oxygen outlet = oxygen produced by the molecular sieve + oxygen mixed in with the air

[0067] 0.5 × 0.2 × 0.01 × x = 1.67 × 10 -4 ×90%+(0.5·0.2×0.01-1.67×10 -4 )×20.95%;

[0068] It can be seen that the volume fraction of the slotted oxygen supply outlet and the grille-type oxygen supply outlet is 26.68%, and the corresponding mass fraction is 28.68%. The average oxygen concentration in the sleep breathing zone can be calculated through numerical simulation. Figure 11 As shown. By comparing the average oxygen concentration in the sleep breathing region under the side-attachment method and the global diffusion method of the second air outlet 4, it was found that over time, the average oxygen concentration in the sleep breathing region under the side-attachment method of the second air outlet 4 was significantly higher than that under the global diffusion method. After 600 seconds of oxygen supply, the oxygen concentration in the sleep breathing region under the side-attachment method was 0.85% higher than that under the global diffusion method. Furthermore, the oxygen supply efficiency of each method was calculated. After 600 seconds of oxygen supply, the oxygen supply efficiency under the side-attachment method of the second air outlet 4 was:

[0069]

[0070] The oxygen supply efficiency under global diffusion mode is:

[0071]

[0072] It can be seen that after 600 seconds of oxygen supply, the oxygen supply efficiency using the side-attachment method of the second air outlet 4 in this application is 14.84% higher than that using the global diffusion method.

[0073] Example 2: As Figure 12 As shown, the oxygen supply device 3 uses the first air outlet 5;

[0074] 1. Oxygen outlet oxygen mass fraction is 90% --- flow rate is 5L / min --- velocity is 0.5m / s

[0075] This embodiment uses the same research subjects as in Embodiment 1. A diffusion oxygen supply device 3 is installed at a height of 0.8m above the head of the bed in the sleep breathing area. The oxygen flow rate of the diffusion oxygen supply device 3 is 10L / min. The first air outlet 5 has a size of 300*10mm and a flow rate of 5L / min. The oxygen mass fraction at the corresponding outlet is 90%, and the oxygen is diffused into the area beside the pillow. In this embodiment, the horizontal diffusion method of the first air outlet 5 in the sleep breathing area under both the downward attachment method and the global diffusion method is compared.

[0076] Average oxygen concentration. The initial oxygen concentration in the sleeping rooms was 20.95%, calculated using the formula:

[0077]

[0078] That is: O2 (mass fraction) - O2 (volume fraction) = 0.2326 - 0.2095 ≈ 2%, so the initial oxygen mass fraction in the sleeping room is 22.95%, and the oxygen mass fraction of both the slot-type and grille-type oxygen supply vents at the first air outlet 5 is 90%. The average oxygen concentration in the sleeping breathing zone can be calculated through numerical simulation. Figure 13 As shown, the oxygen concentration in the sleep breathing area under the lower attachment method was significantly higher than the average oxygen concentration in the sleep breathing area under the global diffusion method, and the effect became more pronounced over time. After 600 seconds of oxygen supply, the oxygen concentration in the sleep breathing area under the lower attachment method was 1.66% higher than the average oxygen concentration in the sleep breathing area under the global diffusion method. Furthermore, the oxygen supply efficiency ε, which represents the ability of oxygen to be delivered from the outlet to the target breathing area, was used to evaluate the local oxygen environment creation capability of the oxygen supply method. The calculation formula is as follows:

[0079]

[0080] C represents the average oxygen concentration in the target breathing zone. s The value ε represents the oxygen supply concentration at the oxygen outlet, and C0 represents the initial oxygen concentration in the hypoxic room. The closer the ε value is to 1, the closer the oxygen concentration in the target breathing zone is to the oxygen supply concentration at the oxygen outlet, and the higher the oxygen supply efficiency.

[0081] Therefore, the oxygen supply efficiency of each oxygen supply method under Example 1 can be calculated. After 600 seconds of oxygen supply, the oxygen supply efficiency under the lower attachment method is:

[0082]

[0083] The oxygen supply efficiency under global diffusion mode is:

[0084]

[0085] It can be seen that after 600 seconds of oxygen supply, the oxygen supply efficiency of the bottom-attach method is 2.47% higher than that of the global diffusion method.

[0086] 2. Oxygen mass fraction at the oxygen outlet is 28.68% --- flow rate is 5L / min --- velocity is 0.5m / s

[0087] In this embodiment, the initial oxygen mass fraction in the sleeping room and the oxygen flow rate of the diffused oxygen supply device 3 are the same as in Embodiment 1. Let x be the volume fraction of the slotted oxygen supply vent and the grille-type oxygen supply vent, calculated using the following formula:

[0088]

[0089] It can be seen that the volume fraction of the slotted and grille-type oxygen supply outlets is 26.68%, corresponding to a mass fraction of 28.68%. The average oxygen concentration in the sleep breathing zone can be calculated through numerical simulation. Figure 14 As shown. The average oxygen concentration in the sleep breathing region was compared between the under-application method and the global diffusion method. Over time, the oxygen concentration in the sleep breathing region under the under-application method was significantly higher than that under the global diffusion method. After 600 seconds of oxygen supply, the oxygen concentration in the sleep breathing region under the under-application method was 1.02% higher than that under the global diffusion method. Furthermore, the oxygen supply efficiency of each oxygen supply method in Example 2 was calculated. After 600 seconds of oxygen supply, the oxygen supply efficiency under the under-application method was:

[0090]

[0091] The oxygen supply efficiency under global diffusion mode is:

[0092]

[0093] It can be seen that after 600 seconds of oxygen supply, the oxygen supply efficiency of the bottom attachment method is 17.81% higher than that of the global diffusion method.

[0094] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
