Technical Field

[0001] This invention relates to the field of micro-pressure modular cabin technology, specifically to a micro-pressure modular cabin with intelligent oxygen absorption function. Background Technology

[0002] Microbaric oxygen chambers increase the partial pressure of oxygen in the blood by increasing oxygen content, thereby improving cell metabolism. Their main functions generally include relieving fatigue, assisting in disease treatment, promoting microcirculation, aiding recovery, and regulating immunity. People living in cities use microbaric oxygen chambers for conditioning, leading to their increasing popularity in civilian use.

[0003] In the utility model entitled "An Extended Container Structure with Positive Pressure Function" (publication number: CN221895957U, publication date: 2024-10-25), the following features include a container body. Doors are rotatably connected to both sides of the container body via adapter shafts. Door latches are located on opposite sides of each door. Mounting plates are fixedly connected to both sides of each door, and the mounting plates are bolted to the container body. A first air extraction pump is fixedly connected to the upper right side of the container body. An air extraction pipe is fixedly connected to the input end of the first air extraction pump. A first filter screen is located at the left end of the air extraction pipe. An air supply pipe is fixedly connected to the output end of the first air extraction pump. This utility model enables the supply of clean, filtered air into the container, preventing microorganisms, dust, or other pollutants from entering and maintaining the cleanliness of the internal environment. Furthermore, it allows for the monitoring and adjustment of the internal environment to maintain predetermined working conditions.

[0004] In existing technologies including the above-mentioned solutions, micro-pressure chambers maintain the pressure inside the chamber at 0.01-0.05 MPa and regulate the oxygen content in the human body by increasing the oxygen content in the air. In existing technologies, a certain amount of oxygen is generally mixed into the air, which is usually controlled by a flow meter. Although it is possible to mix air and oxygen, it requires the addition of oxygen content detection inside the micro-pressure chamber, which greatly increases the cost. Summary of the Invention

[0022] To make the objectives, technical solutions, and advantages of the embodiments of this disclosure clearer, the technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this disclosure. All other embodiments obtained by those skilled in the art based on the described embodiments of this disclosure without creative effort are within the scope of protection of this disclosure.

[0023] Reference Figures 1-4 As shown, the present invention provides a micro-pressure cabin with intelligent oxygen absorption function, including a cabin body 1 and an air channel 1.1: which is connected to the cabin body 1. Oxygen channel 1.2: It is connected to air channel 1.1; Seals: These are installed inside oxygen passage 1.2 and are used to adjust the opening of oxygen passage 1.2; Transmission assembly: It is slidably connected within the air passage 1.1, and one end of it is connected to the seal; When the air pressure drives the transmission component in the air passage 1.1 during its stroke, it drives the seal to move in the oxygen passage 1.2, thereby adjusting the opening of the oxygen passage 1.2 and thus adjusting the oxygen content in the air.

[0024] Specifically, cabin 1 is equipped with an adjustable recliner or an adjustable-angle bed (not shown in the figure). Two sealed doors are rotatably connected to cabin 1, forming a sealed and independent space inside cabin 1. An air channel 1.1 is installed at the upper end of cabin 1, and a removable filter is installed in air channel 1. Air is simply filtered and delivered into cabin 1. An oxygen channel 1.2 is connected to the perimeter of air channel 1.1 and is connected to an oxygen cylinder. The oxygen content in the cabin is increased by mixing the air with oxygen.

[0025] A seal is installed inside the oxygen channel 1.2. The seal is installed inside the oxygen channel 1.2 by sliding, rotating, or a combination of both. The opening of the oxygen channel 1.2 is adjusted by sliding or rotating within the oxygen channel 1.2. When the oxygen flow rate per unit time in the oxygen channel 1.2 is the same, the larger the opening of the oxygen channel 1.2, the more oxygen enters, resulting in a higher oxygen content in the air within the air intake chamber 1 per unit volume. By adjusting the oxygen content of the air in chamber 1 and maintaining the pressure in chamber 1 at 0.01-0.05 MPa, the system can relieve fatigue, assist in disease treatment, promote microcirculation, promote recovery, and regulate immunity.

[0026] The transmission assembly is located in the air passage 1.1. When the air pressure flowing into the air passage 1.1 drives the transmission assembly to move up and down axially within the air passage 1.1, the transmission assembly causes the seal to slide within the oxygen passage 1.2 during its movement. By moving the seal during the movement of the transmission assembly, the oxygen content of the air in the cabin 1 is adjusted.

[0027] In use, air enters the air channel 1.1, causing the air pressure in the air channel 1.1 to drive the transmission component to move. As the transmission component moves downward, it causes the sealing block 1.20 in the oxygen channel 1.2 to move, thereby allowing oxygen and air in the oxygen channel 1.2 to enter the cabin 1, thus regulating the oxygen content in the cabin 1.

[0028] In the above technical solution, the present invention provides a micro-pressure cabin with intelligent oxygen absorption function, which drives the transmission component to move by the air pressure of the inflow in the air channel 1.1, thereby causing the transmission component to drive the sealing part to slide in the oxygen channel 1.2, and adjusting the opening degree of the sealing part in the oxygen channel 1.2 to regulate the amount of oxygen in the air.

[0029] Reference Figures 2-4 As shown, in another embodiment of the present invention, the air channel 1.1 includes a constriction section 1.10, a throat 1.11 and a diffuser section 1.12 arranged sequentially. The diameter of the constriction section 1.10 gradually decreases, the diameter of the throat 1.11 is located at the narrowest point, and the diameter of the diffuser section 1.12 gradually increases.

[0030] The seal comprises two sealing blocks 1.20 that are slidably connected in the radial direction of the oxygen passage 1.2.

[0031] The transmission assembly includes a first drive member slidably connected to the throat 1.11 and a second drive member connected to the seal.

[0032] The first driving component includes a slider 1.5 movably connected to the throat 1.11, and the slider 1.5 is connected to the air passage 1.1 by a spring 1.50.

[0033] The second driving component includes a transmission component 1.6 slidably connected within the oxygen channel 1.2. The transmission component 1.6 includes an abutment portion 1.61, which is used to drive each sealing block 1.20 to slide within the oxygen channel 1.2.

[0034] A transmission pin 1.51 is fixedly connected to the sliding member 1.5, and a wedge-shaped groove 1.60 adapted to the transmission pin 1.51 is provided on the transmission member 1.6.

[0035] Each sealing block 1.20 has a transmission groove 1.201 that matches the abutment part 1.61.

[0036] An intake fan 1.4 is installed in the air passage 1.1 at the position of the contraction section 1.10.

[0037] An exhaust channel 1.3 is also installed on the hull 1, and an exhaust fan 1.30 is installed inside the exhaust channel 1.3.

[0038] Specifically, such as Figures 2-3As shown, the air passage 1.1 consists of three sections, from top to bottom: a contraction section 1.10, a throat 1.11, and a diffuser section 1.12. The diameter of the contraction section 1.10 gradually decreases, the throat 1.11 is at its narrowest point, and the diffuser section 1.12 gradually increases in diameter. This forms a Venturi tube structure within the air passage 1.1. The gradually decreasing diameter of the contraction section 1.10 increases the fluid velocity and decreases the pressure. The throat 1.11, at its narrowest point, has the highest flow velocity and the lowest static pressure. The gradually increasing diameter of the diffuser section 1.12 decreases the fluid velocity and reduces the pressure within the air passage 1.1. An intake fan 1.4 is installed above the contraction section 1.10. An oxygen channel 1.2 is connected through the air channel 1.1 at the position of the throat. Two sealing blocks 1.20 are slidably connected radially to the oxygen channel 1.2. The two sealing blocks 1.20 are used to open or close the oxygen channel 1.2. The two sealing blocks 1.20 are slidably connected in the oxygen channel 1.2 to adjust the opening degree of the oxygen channel 1.2. An exhaust channel 1.3 is connected through the side wall of the cabin 1 near the bottom. An exhaust fan 1.30 is installed in the exhaust channel 1.3.

[0039] A sliding member 1.5 is slidably connected within the air passage 1.1 at the position of the throat tube, such as... Figure 4 As shown, the upper end of the sliding member 1.5 is provided with a conical structure, the outer diameter of which is smaller than the inner diameter of the throat. A transmission pin 1.51 is fixedly connected to the sliding member 1.5. The sliding member 1.5 includes an abutment part 1.61 that is axially slidably connected in the oxygen channel 1.2. Each sealing block 1.20 has a transmission groove 1.201 that is adapted to the abutment part 1.61 at the position corresponding to it. The sliding member 1.5 is fixedly connected to the transmission member 1.6. The transmission member 1.6 is fixedly connected to the air channel 1.1 by a spring 1.50. One end of the spring 1.50 is fixedly connected to the air channel 1.1, and the other end of the spring 1.50 is fixedly connected to the transmission member 1.6. In this embodiment, the wind speed of the intake fan 1.4 and the exhaust fan 1.30 can be adjusted, that is, the intake fan 1.4 and the exhaust fan 1.30 are frequency converters. A pressure sensor is provided in the cabin 1 to maintain the pressure in the cabin 1 within 0.01-0.05 MPa.

[0040] During operation, when the intake fan 1.4 starts and supplies air into the cabin 1, the air pressure in the air passage 1.1 pushes the sliding member 1.5 to move, causing the transmission pin 1.51 on the sliding member 1.5 to move within the wedge groove 1.60. The downward movement of the sliding member 1.5 drives the transmission member 1.6 to move within the oxygen passage 1.2, which in turn causes the transmission member 1.6 to abut against the sealing block 1.20. This downward movement of the sliding member 1.5 opens the oxygen passage 1.2, thus regulating the oxygen content in the air using the principle of a venturi tube. Furthermore, the coordinated operation of the exhaust fan 1.30 and the intake fan 1.4 regulates the air pressure within the cabin 1, maintaining the pressure within the cabin 1 at 0.01-0.05 MPa.

[0041] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
