Description

Technical Field

[0001] The utility model relates to the technical field of oxygen supply equipment, in particular to an attached diffusion oxygen supply equipment with adjustable height and angle. Background Art

[0002] In high-altitude areas, the special low-pressure and oxygen-deficient environment can cause support personnel, business travelers, and other outsiders to experience symptoms such as decreased physical strength, dizziness, and nausea while sleeping. Therefore, they need to be provided with a suitable oxygen-rich environment to meet their sleep needs.

[0003] Oxygen enrichment is a common solution to the hypoxic environment of the plateau. Oxygen enrichment reduces symptoms of altitude sickness and insomnia by providing an oxygen-rich environment, effectively improving sleep quality. Currently, full-space and localized diffuse oxygen supply are the primary methods for indoor oxygen enrichment in high-altitude buildings. While full-space oxygen supply can diffuse oxygen from the air supply terminal throughout the entire indoor space, it is slow and prone to uneven spatial distribution of oxygen concentration, resulting in low oxygen enrichment efficiency and energy waste. Localized diffuse oxygen supply, on the other hand, delivers oxygen to the work area in a targeted manner, avoiding energy waste and is a common method for creating an oxygen-enriched indoor environment.

[0004] The attached diffuse oxygen supply device is a new type of local diffuse oxygen supply equipment, which is installed on the head of the bed near the upper side of the rest area and near the breathing area. The diffuse oxygen supply device is provided with an air outlet in the area near the head of the human body in the rest area. When the oxygen production device is turned on, oxygen forms a jet through the air outlet of the diffuse oxygen supply device, flows forward along the vertical plane, impacts the plane of the device, and then diffuses and flows horizontally to complete the indoor diffuse oxygen supply. The oxygen supply device with the above structure has a simple structure and low energy consumption. It can quickly and efficiently increase the oxygen concentration in the sleeping and breathing areas of plateau buildings. However, due to its fixed position, it is difficult to meet the different bed heights and personalized needs of personnel. Utility Model Content

[0034] The present invention will be further described in detail below with reference to the accompanying drawings, which are intended to explain rather than limit the present invention.

[0035] In order to help those skilled in the art better understand the present invention, the following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of the present invention.

[0036] It should be noted that the terms "first", "second", etc. in the specification and claims of the present invention and the above-mentioned drawings are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that the numbers used in this way can be interchanged where appropriate, so that the embodiments of the present invention described herein can be implemented in an order other than those illustrated or described herein. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions. For example, a process, system, product or device that includes a series of steps or units is not necessarily limited to those steps or units that are clearly listed, but may include other steps or units that are not clearly listed or that are inherent to these processes, products or devices.

[0037] Figure 1 An embodiment of the present disclosure shows an attached diffuse oxygen supply device with adjustable height and angle, such as Figure 1 As shown, it includes an attached diffuse oxygen supply body 1 and a telescopic bracket 3 connected to the attached diffuse oxygen supply body 1 through a connecting piece 2. The attached diffuse oxygen supply body 1 is arranged on the respiratory side of the rest area;

[0038] The attached diffuse oxygen supply body 1 comprises a mixing static pressure box 102 , the input end of the mixing static pressure box 102 is connected to the oxygen supply pipe 101 , and a flow guide component is provided on the output side.

[0039] It should be noted that in the embodiment of the present disclosure, the rest area can be, for example, a seating rest area in a hotel lounge, or around the head of a bed, around a desk, etc. The breathing zone refers to the position close to the mouth and nose when the resting person is in a resting posture that may be in the resting posture in the resting area, and the resting posture includes standing, sitting, lying, etc.

[0040] In some preferred embodiments, Figure 2 As shown, the mixing static pressure box 102 is provided with an air outlet vertically downward, and the air outlet is a slit-type structure;

[0041] A vertically downward attachment plate 103 is provided at the bottom of the mixing static pressure box 102 , and the attachment plate 103 is provided on a side of the air outlet close to the wall.

[0042] It should be noted that, in some embodiments, a plurality of guide devices are provided inside the mixing static pressure box 102 , and the exhaust air can be made diffuse by the plurality of guide devices in conjunction with the air outlet and the attachment plate 103 .

[0043] The diffusion type sends oxygen out in the form of a jet through the air outlet. The jet moves forward along the wall surface, then flows vertically downward, passes through the breathing zone of the human head, hits the ground and turns into a horizontal diffusion flow, thereby completing the indoor diffuse oxygen supply.

[0044] In some preferred embodiments, Figure 3 As shown, a flow guide component is provided at the bottom of the attachment plate 103 , and the flow guide component includes a baffle 105 . A rotating shaft core 104 is provided between the attachment plate 103 and the baffle 105 .

[0045] Specifically, the rotating axis core 104 includes a first rotating cylinder 106, and a second rotating cylinder 107 that is coaxially sleeved in the first rotating cylinder 106 with interference fit. The first rotating cylinder 106 and the second rotating cylinder 107 are both provided with windows 109, and the side walls of the windows 109 of the second rotating cylinder 107 are provided with fan-shaped protrusions 111. It should be noted that the first rotating cylinder 106 and the second rotating cylinder 107 rotate relative to each other through the fan-shaped protrusions 111. Since the first rotating cylinder 106 and the second rotating cylinder 107 are interference fit, after rotation, a relatively stable state will be formed to maintain the angle.

[0046] In some preferred embodiments, Figure 5 As shown, the telescopic bracket 3 includes multiple stages of telescopic legs 301 that are sequentially sleeved, and a driving assembly disposed in the telescopic legs 301;

[0047] Specifically, the driving assembly includes a multi-stage telescopic guide rod 400 that is sequentially sleeved, and the multi-stage telescopic guide rod 400 is consistent in length with the multi-stage telescopic leg 301;

[0048] It also includes a driving member, which is arranged on the rod body of the tail-stage telescopic guide rod 400. The driving member includes a driving motor 500 and a driving wheel 501 arranged at the output end of the driving motor 500. The driving wheel 501 is wrapped with a transmission belt 502. The inner wall of the first-stage telescopic leg 301 is provided with multiple driven wheels 503. One end of the transmission belt 502 is fixedly provided on the transmission belt 502, and the other end is fixedly provided on the driven wheel 503 at the terminal of the transmission path formed by the multiple driven wheels 503.

[0049] It should be noted that the driving wheel 501 and multiple driven wheels 503 together constitute the transmission path of the transmission belt 502. When the multi-stage telescopic leg 301 needs to be folded, the driving motor 500 is started, and the driving motor 500 drives the driving wheel 501 to rotate and wrap the transmission belt 502 around itself. Since the driving motor 500 is arranged on the rod body of the last-stage telescopic guide rod 400, it starts to retract from the last-stage telescopic leg 301 until all the telescopic legs 301 are retracted. If the multi-stage telescopic leg 301 needs to be unfolded, the driving motor 500 can be rotated in the opposite direction.

[0050] Furthermore, in an embodiment of the present disclosure, the side walls of the telescopic guide rods 400 that are sleeved on each other are provided with guide slots with compatible structures; the side walls of the telescopic guide rods 400 that are sleeved on each other are provided with guide slots with compatible structures.

[0051] It should be noted that the guide slots are used to improve the stability of the telescopic guide rod 400 and the telescopic guide rod 400 during the telescopic process, and to prevent problems such as deviation.

[0052] In some preferred embodiments, Figure 4 As shown, the connecting member 2 includes a plug-in 201 and a clamping member 202. One end of the plug-in is fixedly connected to the side wall of the attached diffuse oxygen supply body 1, and the other end is interference-rotatably clamped to one end of the clamping member 202. The other end of the clamping member 202 is fixedly connected to the side wall of the telescopic bracket 3.

[0053] Specifically, one end of the plug-in 201 close to the clamping member 202 is a spherical structure, and one end of the clamping member 202 close to the plug-in 201 is a spherical groove, and the spherical structure is rotated and clamped in the spherical groove by interference fit.

[0054] It should be noted that, in the embodiment of the present disclosure, the plug-in 201 and the clamp 202 constitute a spherical universal joint, which can achieve adjustment at any angle.

[0055] Preferably, in some embodiments, the input end of the oxygen supply tube 101 is connected to an oxygen generator, and the output end of the oxygen generator is provided with a blower and a humidifier bottle. It should be noted that the blower mainly plays the role of transporting oxygen in the oxygen generator. It can ensure that oxygen is smoothly output from the oxygen generator and maintain a certain airflow speed and pressure. Through the operation of the blower, oxygen can be effectively transported to where it is needed, such as a humidifier bottle or directly to the user. The main function of the humidifier bottle is to humidify the oxygen to make it closer to the humidity of natural human breathing. Dry oxygen may cause discomfort to the user and even cause respiratory problems. Therefore, the use of a humidifier bottle is very important. It usually contains water or other wetting agents to ensure that the output oxygen has an appropriate humidity. When the blower transports the oxygen to the humidifier bottle, the oxygen will be humidified, making it more comfortable and easy to inhale. This configuration ensures that the user can receive both sufficient and humidified oxygen, thereby improving the comfort and effect of use.

[0056] Example 1: Attached diffuse oxygen supply device with different angles between baffle and attachment plate;

[0057] The mass fraction of oxygen at the oxygen outlet is 90% --- flow rate 10L / min --- speed 0.5m / s --- height from the ground 30cm;

[0058] This embodiment takes a sleeping space in a plain area of ​​7.5m×3.7m×3m (L×W×H) as the research object. A bed is distributed in the building space, and the bed's 10 dimensions are 2m×1.2×0.2m (L×W×H). A human dummy is placed on the bed, and an attached diffuse oxygen supply device is installed 30cm away from the sleeping breathing area at the head of the bed. The angles between the baffle and the attached plate are adjusted to 90 degrees, 105 degrees, and 120 degrees respectively. The initial oxygen mass fraction in the breathing area and the right ear of the dummy and the oxygen mass fraction after 3600s are tested; in this embodiment, the average oxygen concentration in the sleeping breathing area under different angles between the baffle and the attached plate are compared. The initial oxygen volume fraction of the sleeping room is 20.95%, as shown in FIG. Figure 7 and 8 As shown. When the angle between the baffle and the attachment plate is 120°, the oxygen concentration in the sleeping breathing area and the area near the right ear is higher than the average oxygen concentration in the sleeping breathing area at other angles. After 600 seconds of oxygen supply, the oxygen concentration in the sleeping breathing area at the angle of 120° is 0.85% higher than the average oxygen concentration in the sleeping breathing area at other angles. In addition, by calculating the oxygen supply efficiency ε, which represents the ability of oxygen to be transported from the oxygen outlet to the target breathing area, the oxygen supply efficiency is used to evaluate the local oxygen environment creation ability of the oxygen supply method. The calculation formula is as follows:

[0059]

[0060] Indicates the average oxygen concentration in the target breathing zone, C s 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.

[0061] Thus, the oxygen supply efficiency of each oxygen supply mode under Example 1 can be calculated. After 1200s of oxygen supply, the oxygen supply efficiency at an angle of 120° is:

[0062]

[0063] The oxygen supply efficiency at a 90° angle is:

[0064]

[0065] It can be seen that after 1200s of oxygen supply, the oxygen supply efficiency at 120 degrees is 1.2% higher than that at 90 degrees, and both meet the A-level standard for plateau oxygen supply at an altitude of 3000m (GB / T 35414-2017).

[0066] Example 2: Attached diffused oxygen supply devices at different heights;

[0067] Except for the height, other conditions of this example are the same as those of Example 1.

[0068] Example 2: Oxygen increase rate of the attached diffuse oxygen supply device at different angles at a height of 0.35m from the ground;

[0069] Except for the height, all other conditions in this example are the same as those in Example 1. In this example, the oxygen increase rate in the sleeping breathing zone at different angles between the baffle and the attachment plate is compared to evaluate the effect of changing the angle on the oxygen concentration in the sleeping breathing zone at an altitude of 0.35m above the ground.

[0070] The oxygenation rate formula describes the rate of change of oxygen concentration over time. To describe the oxygenation rate in detail, the following formula can be used:

[0071] Oxygenation rate = dC / dt,

[0072] The stable oxygen concentration C0 and the initial oxygen concentration C1 are usually expressed as volume concentration percentages.

[0073] At 0:00, turn on the oxygen concentrator and the attached diffuse oxygen supply device to monitor and record the oxygen concentration in the breathing zone of the personnel. The trend of oxygen volume concentration over time is as follows: Figure 10When the angle between the baffle and the attachment plate is 90°, the oxygen concentration at this angle is calculated using the target oxygen concentration of 24.7% in the Class A standard at an altitude of 3500m, as specified in the requirements for diffuse oxygen supply (oxygen conditioning) for indoor spaces in plateau areas (GB / T35414-2017). The initial oxygen concentration, C_0, is 21.01%, and the time required to reach the target oxygen concentration is 100 minutes. The oxygen increase rate, dC / dt, is 0.03% / min, with an initial oxygen concentration of C_0 = 21.01%. The time required to reach the target oxygen concentration is 100 minutes.

[0074] Calculate the oxygen increase rate at 105°, where the initial oxygen concentration C0 = 20.9%, the stable oxygen concentration C1 = 24.7%, the time taken to reach the target oxygen concentration is 60 minutes, and the oxygen increase rate dC / dt = (24.7% - 20.9%) / 60 minutes = 0.06% / min. When the angle between the baffle and the attachment plate is 120°, the initial oxygen concentration C_0 = 20.9%, the time taken to reach the target oxygen concentration is 20 minutes, and the oxygen increase rate: dC / dt = (24.7% - 20.9%) / 20 minutes = 0.19% / min. It can be seen that at 0.45 meters from the ground, the oxygen increase rate at 120° is about 6.3 times higher than that at 90°, which is a significant effect. In an environment where there is an urgent need for oxygen, the oxygen increase rate can be increased by increasing the angle to better meet the needs of various usage scenarios. In addition, after stabilization, the oxygen concentration at 120° is 0.61% higher than that at 90°, which is of great significance to the concentration requirements of diffuse oxygen supply equipment at higher altitudes. Figure 9 As shown, when the oxygen supply device is at different heights from the ground, adjusting the baffle and the attachment plate to different angles can increase the oxygenation rate to meet personalized needs.

[0075] By adjusting the angle between the baffle and the attachment plate, the oxygenation rate and final oxygen concentration can be significantly increased, ensuring oxygen supply requirements in different operating environments. This simple and effective method is suitable for various situations requiring a rapid increase in oxygen concentration, such as high altitude areas, emergency medical environments, and other scenarios with high oxygen concentration requirements.

[0076] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it.
