Description

Technical Field

[0001] This utility model relates to the field of oxygen chambers, and more specifically, to a micro-high pressure rigid oxygen chamber. Background Technology

[0002] With the increasing awareness of public health, hyperbaric oxygen therapy is being used more and more widely, not only for the clinical treatment of carbon monoxide poisoning, decompression sickness, and air embolism, but also showing great potential in areas such as sports rehabilitation, sleep improvement, and anti-aging health care. Micro hyperbaric oxygen chambers, as a miniaturized and more accessible version of traditional medical hyperbaric oxygen chambers, are gradually entering homes, rehabilitation centers, beauty salons, and other locations. Currently, most micro hyperbaric oxygen chambers on the market are of a single-piece structure. While this structure is strong, it is bulky, making transportation and home installation extremely difficult. Furthermore, if an internal malfunction occurs, the limited space for repairs leads to very high maintenance costs. In addition, many existing oxygen chambers have separate designs for their oxygen supply, pressure, and temperature control systems. This separate design results in large equipment footprints, messy pipeline layouts, and complex installation and debugging, leading to inconvenience in use. Utility Model Content

[0003] In view of this, the present invention provides a micro-high pressure rigid oxygen chamber that integrates key functions, is easy to transport and install, and has extremely high sealing reliability and safety.

[0004] The objective of this utility model is achieved through the following technical solution: A micro-high-pressure rigid oxygen chamber includes a chamber body and a control cabinet. The control cabinet houses an oxygen generator, a compressor unit, and a water-cooling unit, which are connected to the interior of the chamber body via gas pipes. The chamber body includes a detachably connected front shell and a rear shell, with a first sealing ring at the joint between the front shell and the rear shell. A door assembly is provided on the front shell, and the door assembly is sealed to the interior of the chamber body via a second sealing ring.

[0005] In the above technical solution, the control cabinet integrates core functional modules, such as oxygen generator, compressor unit, and water-cooled unit, into one unit and connects to the cabin through gas pipes, which greatly reduces the complexity and time of on-site installation. It also facilitates the subsequent independent maintenance, replacement or upgrade of specific units, reducing maintenance costs and time.

[0006] The cabin employs a detachable front and rear shell design, allowing it to be disassembled to reduce the size of individual components, thus facilitating manufacturing and transportation. More importantly, it greatly facilitates the installation, routine cleaning and maintenance, and major repairs of the cabin and its internal components. The first sealing ring at the joint ensures the static sealing reliability of the main cabin structure, laying the foundation for maintaining a stable micro-high pressure environment inside the cabin.

[0007] Furthermore, this invention employs a dual-sealing design. The first sealing ring provides a static seal for the main body of the chamber, while a second sealing ring ensures a dynamic seal between the door assembly and the chamber. This dual-safety mechanism significantly enhances the overall airtightness and safety of the oxygen chamber, effectively preventing pressure leakage, ensuring a stable pressure environment within the chamber during treatment, and protecting the user's personal safety.

[0008] Optionally, in one possible implementation, a first flange is provided on the front housing, and a second flange matching the first flange is provided on the rear housing. The first flange and the second flange are fixedly connected by screws, and the first sealing ring is located between the first flange and the second flange.

[0009] In the above technical solution, the flange connection method has high connection strength and stability. Under micro-high pressure environments, it can withstand significant pressure without loosening or separation, ensuring the integrity of the cabin structure and providing users with a safe and reliable operating space, effectively avoiding safety accidents caused by unstable cabin connections. Secondly, the first sealing ring effectively prevents gas leakage from the cabin connection, ensuring stable pressure within the cabin.

[0010] Optionally, in one possible implementation, the cabin further includes a first decorative panel and a second decorative panel, which are located on opposite sides of the cabin and are used to cover the joint gap between the front shell and the rear shell.

[0011] In the above technical solution, the first and second decorative panels cover the joint gap between the front and rear shells, making the cabin appearance cleaner and more aesthetically pleasing, eliminating the visual disharmony caused by the joint gap, and improving the overall appearance. Furthermore, they also provide some protection to the joint areas of the cabin, preventing external dust and debris from entering the joint gap and reducing the problem of decreased sealing performance due to the accumulation of foreign matter.

[0012] Alternatively, in one possible implementation, a doorway is provided on the side of the front housing away from the rear housing, and the door assembly is installed at the doorway.

[0013] In the above technical solution, the door opening and door assembly provide users with a clear and convenient access route. Users can easily open the door assembly to enter the cabin, which also facilitates the maintenance and upkeep of the cabin.

[0014] Optionally, in one possible implementation, the door assembly includes a door frame and a door panel, the door frame being installed in the door opening and one end extending into the cabin; the second sealing ring is disposed on the door frame, and the door panel is rotatably connected to the front housing and pressed against the second sealing ring in the closed state.

[0015] In the above technical solution, the second sealing ring is installed on the door frame. When the door panel is closed and pressed against the second sealing ring, a multi-layered sealing structure is formed. This effectively prevents the exchange of gases between the inside and outside of the cabin, ensuring stable internal pressure and preventing oxygen leakage under micro-high pressure conditions. Secondly, the door panel does not require a locking mechanism. When the door panel is closed, because the internal air pressure is greater than the external air pressure, the door panel can achieve a self-tightening seal under the pressure within the cabin, thus improving ease of use and safety.

[0016] Optionally, in one possible implementation, an extension block is provided at one end of the door frame located inside the cabin, the extension block being perpendicular to the door frame; the second sealing ring has a "U" shaped cross-section structure, and the second sealing ring is snapped onto the extension block.

[0017] In the above technical solution, the structural design of the second sealing ring makes its connection with the door frame more stable, effectively preventing the sealing ring from shifting or falling off under pressure, while also increasing the contact area between the sealing ring and the door frame and door panel. When the door panel is closed and pressed against the sealing ring, the larger contact area can provide more uniform sealing pressure, effectively filling the tiny gaps between the door frame and door panel, and further preventing gas leakage.

[0018] Optionally, in one possible implementation, a fixing plate is provided on the inner side of the front housing, and one side of the door panel is rotatably mounted on the fixing plate via several hinges.

[0019] In the above technical solution, the fixed plate provides a solid and stable support foundation for the installation of the door panel. Several hinges are used to rotate and mount the door panel onto the fixed plate. The hinges can evenly distribute the force generated when the door panel is opened and closed, preventing damage to the front housing or door panel due to excessive localized stress. This installation method makes the connection between the door panel and the front housing more secure.

[0020] Optionally, in one possible implementation, door handles are installed on both the inner and outer sides of the door panel.

[0021] In the above technical solution, door handles are installed on both the inner and outer sides of the door panel, so that users can easily open and close the door panel whether they are inside or outside the cabin.

[0022] Optionally, in one possible implementation, a booster pump is also provided inside the control cabinet, and the booster pump is located on the gas pipe connected to the oxygen generator unit.

[0023] In the aforementioned technical solution, within the oxygen chamber system, oxygen generated by the oxygen generator is delivered to the chamber via tubing. However, increased pressure within the chamber can lead to a decrease in oxygen flow. A booster pump can regulate and stabilize the oxygen pressure in real time. When the oxygen pressure falls below a set value, the booster pump automatically activates, increasing the oxygen pressure to ensure the pressure delivered to the oxygen chamber remains stable within a suitable range. This provides a stable and reliable oxygen supply to patients or users, guaranteeing treatment effectiveness and safety.

[0024] Optionally, in one possible implementation, the bottom of the cabin and the bottom of the control cabinet are both provided with multiple omnidirectional casters.

[0025] In the above technical solution, the omnidirectional casters can rotate freely 360 degrees, allowing operators to easily push the cabin and control cabinet and move flexibly in all directions, which facilitates the installation, commissioning, maintenance, and site changes of the oxygen chamber.

Detailed Implementation

[0033] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0034] Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely to illustrate selected embodiments of the application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0035] Please refer to Figures 1-5 This embodiment provides a micro-high-pressure rigid oxygen chamber, including a chamber body 1 and a control cabinet 2. The control cabinet 2 is equipped with an oxygen generator 21, a compressor unit 22, and a water-cooling unit 23. The oxygen generator 21, compressor unit 22, and water-cooling unit 23 are connected to the interior of the chamber body 1 through air pipes 3. The compressor unit 22 generates high-pressure air and inputs it into the chamber body 1, increasing the air pressure inside the chamber body 1. The oxygen generator 22 generates a high concentration of oxygen and inputs it into the chamber body 1 for human respiration. The water-cooling unit 23 cools the circulating water to lower the temperature inside the chamber body 1. The chamber body 1 includes a detachably connected front shell 11 and a rear shell 12. A first sealing ring 4 is provided at the joint between the front shell 11 and the rear shell 12. A door assembly 5 is provided on the front shell 11, and the door assembly 5 is sealed to the interior of the chamber body 1 through a second sealing ring 6.

[0036] In this embodiment, the control cabinet 2 integrates core functional modules, such as oxygen generator 21, compressor unit 22, and water-cooled unit 23, into one unit and connects to the cabin 1 through the air pipe 3. This greatly reduces the complexity and time of on-site installation and also facilitates subsequent independent maintenance, replacement, or upgrade of specific units, reducing maintenance costs and time.

[0037] The cabin 1 adopts a detachable front shell 11 and rear shell 12 design, which allows it to be disassembled to reduce the volume of individual components, thereby facilitating production, manufacturing, and transportation. More importantly, it greatly facilitates the installation, routine cleaning and maintenance, and major repairs of the cabin 1 and its internal components. The first sealing ring 4 set at the joint ensures the static sealing reliability of the main structure of the cabin 1, laying the foundation for maintaining a stable micro-high pressure environment inside the cabin.

[0038] Furthermore, this embodiment employs a dual-sealing design. The first sealing ring 4 provides a static seal for the main body of the chamber 1, while the door assembly 5 and the chamber 1 are dynamically sealed via a second sealing ring 6. This dual-safety mechanism significantly enhances the overall airtightness and safety of the oxygen chamber, effectively preventing pressure leakage, ensuring a stable pressure environment within the chamber during treatment, and protecting the user's personal safety.

[0039] It should be noted that the compressor unit 22, oxygen generator unit 21, and water-cooled unit 23 inside control cabinet 2 are all existing conventional equipment. High-pressure air and high-concentration oxygen are delivered to the chamber 1 through the air pipe 3, creating high pressure in the sealed chamber 1. People can inhale high-concentration oxygen under this high pressure, allowing the oxygen to dissolve more fully into the blood, thus improving tissue function, promoting blood circulation, and enhancing cell vitality. In addition, chamber 1 contains a television, sofa, lighting, air conditioning evaporator, control panel, oxygen inhalation nozzle, etc., whose main function is to create a closed, high-pressure environment, allowing people to inhale oxygen and maintain their health in a comfortable setting.

[0040] When using chamber 1, turn on the power switch, set the desired parameters on the control cabinet 2 panel, then open the chamber door to enter. After closing the door, sit on the sofa and put on the oxygen mouthpiece to inhale oxygen. As the pressure inside the chamber increases, the pressure and oxygen concentration parameters will change. Adjustments can be made by observing the control screen inside the chamber and by adjusting the air conditioning temperature. While inhaling oxygen, you can watch television entertainment programs or close your eyes to rest. In case of any abnormality, you can contact the outside world through the intercom, or pause the pressurization process, press the manual pressure relief valve to release pressure, and then open the door to exit the oxygen chamber. Chamber 1 is equipped with an automatic pressure relief valve, an emergency pressure relief valve, and a manual pressure relief valve to ensure personal safety in abnormal situations.

[0041] Please refer to Figure 2In this embodiment, a first flange (not shown in the figure) is provided on the front housing 11, and a second flange 121 matching the first flange is provided on the rear housing 12. The first flange and the second flange 121 are fixedly connected by screws, and a first sealing ring is located between the first flange and the second flange 121. The first flange and the second flange 121 are provided with a plurality of corresponding screw holes, which are distributed circumferentially along the first flange or the second flange 121 to ensure tight connection between the first flange and the second flange 121 at all points.

[0042] The flange connection method offers high connection strength and stability. Under micro-high pressure environments, it can withstand significant pressure without loosening or separation, ensuring the structural integrity of compartment 1 and providing users with a safe and reliable operating space. This effectively prevents safety accidents caused by unstable connections in compartment 1. Secondly, the first sealing ring is located between the first flange and the second flange 121. During the tightening of the bolts, the flanges exert a uniform compression force on the sealing ring, ensuring a tight fit between the sealing ring and the contact surfaces of the two flanges, forming a good sealing barrier. This effectively prevents gas leakage from the connection point of compartment 1, ensuring stable pressure within compartment 1.

[0043] In addition, the front housing 11 and the rear housing 12 can also be connected by clamps. For example, grooves can be provided at the connection points of the front housing 11 and the rear housing 12, and then clamps can be used to tighten the two housings together. The clamps are usually made of metal and have a certain degree of elasticity and strength. The tightness of the clamps is adjusted to achieve the fixation and sealing of the housings.

[0044] Please continue to refer to this. Figure 2 In this embodiment, the cabin 1 further includes a first decorative panel 13 and a second decorative panel 14. The first decorative panel 13 and the second decorative panel 14 are located on opposite sides of the cabin 1 and are used to cover the joint gap between the front shell 11 and the rear shell 12. The first decorative panel 13 and the second decorative panel 14 are fixed to the front shell 11 and the rear shell 12 by adhesive or snap-fit.

[0045] The first decorative panel 13 and the second decorative panel 14 cover the joint gap between the front shell 11 and the rear shell 12, making the appearance of the cabin 1 neater and more beautiful, eliminating the visual disharmony caused by the joint gap, and improving its aesthetics. They also provide some protection to the joint area of ​​the cabin 1, preventing external dust and debris from entering the joint gap and reducing the problem of decreased sealing performance due to the accumulation of foreign matter.

[0046] Of course, the first decorative panel 13 and the second decorative panel 14 can also be replaced by decorative strips. Decorative strips matching the style of the hull 1 can be selected and glued to both sides of the joint between the front shell 11 and the rear shell 12 using adhesive, with the edges of the decorative strips used to cover the gap. The decorative strips can be made of different materials such as metal, plastic, or wood, and offer a wide range of colors and shapes to choose from.

[0047] In this embodiment, a doorway is provided on the side of the front housing 11 away from the rear housing 12, and the door assembly 5 is installed at the doorway. The doorway and door assembly 5 provide users with a clear and convenient access route, allowing users to easily open the door assembly 5 to enter the interior of the cabin 1, while also facilitating the maintenance and upkeep of the cabin 1.

[0048] Please refer to Figures 2-4 Specifically, the door assembly 5 includes a door frame 51 and a door panel 52. The door frame 51 is installed in the door opening and one end extends into the cabin 1. The second sealing ring 6 is provided on the door frame 51. The door panel 52 is rotatably connected to the front housing 11 and is pressed against the second sealing ring 6 in the closed state.

[0049] The second sealing ring 6 is installed on the door frame 51. When the door panel 52 is closed and pressed against the second sealing ring 6, a multi-layer sealing structure is formed. This effectively prevents the exchange of gases inside and outside the cabin 1, ensuring stable internal pressure and preventing oxygen leakage under micro-high pressure conditions. Furthermore, the door panel 52 does not require a locking mechanism. When the door panel 52 is closed, because the internal air pressure is greater than the external air pressure, the door panel 52 can achieve a self-tightening seal within 10-15 seconds under the pressure inside the cabin 1, thus improving ease of use and safety.

[0050] Please refer to Figure 4 In this embodiment, the door frame 51 located inside the cabin 1 has an extension block 511 at one end. The extension block 511 is perpendicular to the door frame 51 and surrounds the door frame 51. The extension block 511 and the door frame 51 form an "L" shaped cross-section. The second sealing ring 6 has a "U" shaped cross-section structure. The second sealing ring 6 matches the extension block 511, that is, it is also surrounded by the door frame 51. The second sealing ring 6 is snapped onto the extension block 511.

[0051] The structural design of the second sealing ring 6 makes its connection with the door frame 51 more stable, effectively preventing the sealing ring from shifting or falling off under pressure. It also increases the contact area between the sealing ring and the door frame 51 and door panel 52. When the door panel 52 is closed and pressed against the sealing ring, the larger contact area provides more uniform sealing pressure, effectively filling the tiny gaps between the door frame 51 and door panel 52, further preventing gas leakage. Secondly, during the use of the oxygen chamber, a certain pressure is maintained inside the chamber 1, which exerts an outward force on the door. The cooperation of the "U"-shaped structure and the extension block 511 effectively prevents the second sealing ring 6 from shifting or falling off under pressure, thus ensuring long-term stability of the sealing performance and creating a safe and reliable environment inside the chamber.

[0052] It should be noted that magnetic material can also be embedded at one end of the door frame 51 located inside the cabin 1, and a corresponding magnetic material or metal sheet can be embedded in the second sealing ring 6. The sealing ring is attracted to the door frame 51 using magnetic attraction, thus achieving a sealing function. The cross-sectional shape of the sealing ring can be designed according to actual needs, such as an "L" shape or a "T" shape, to better fit with the door frame 51 and the door panel 52.

[0053] Please refer to Figure 3 In this embodiment, a fixing plate 111 is provided on the inner side of the front housing 11, and one side of the door panel 52 is rotatably mounted on the fixing plate 111 via several hinges 112. The fixing plate 111 provides a solid and stable support foundation for the installation of the door panel 52. By rotatably mounting the door panel 52 on the fixing plate 111 via several hinges 112, the hinges 112 can evenly distribute the force generated when the door panel 52 is opened and closed, avoiding damage to the front housing 11 or the door panel 52 due to excessive local force. This installation method makes the connection between the door panel 52 and the front housing 11 more secure.

[0054] Please refer to Figure 3 In this embodiment, door handles 521 are installed on both the inner and outer sides of the door panel 52. With door handles 521 installed on both the inner and outer sides of the door panel 52, the user can easily open and close the door panel 52 whether inside or outside the cabin.

[0055] In this embodiment, the control cabinet 2 is also equipped with a booster pump 211, which is located on the pipeline of the air pipe 3 connected to the oxygen generator unit 21. In the oxygen chamber system, the oxygen generated by the oxygen generator unit 21 is delivered to the chamber 1 through the air pipe 3. However, an increase in pressure inside the chamber 1 will cause the oxygen flow rate to decrease. The booster pump 211 can adjust and stabilize the oxygen pressure in real time. When the oxygen pressure is lower than the set value, the booster pump 211 automatically starts to increase the oxygen pressure, ensuring that the oxygen pressure delivered to the oxygen chamber is stable within a suitable range, providing a stable and reliable oxygen supply for the patient or user, and ensuring the treatment effect and safety.

[0056] Please refer to Figure 1 In this embodiment, multiple omnidirectional casters 7 are provided at the bottom of both the cabin 1 and the control cabinet 2. The omnidirectional casters 7 can rotate freely 360 degrees, allowing operators to easily push the cabin 1 and control cabinet 2 and move them flexibly in all directions, facilitating the installation, commissioning, maintenance, and site changes of the oxygen chamber.
