The miniaturization and lightweight of portable oxygen concentrator with battery are of great significance to improving its portability and user experience, and require comprehensive consideration and innovative design from multiple aspects.
First of all, in the oxygen production technology link, the development of efficient and compact oxygen production modules is the core. Traditional oxygen production technology often relies on large-volume molecular sieve adsorption towers and compressors and other components. Nowadays, new molecular sieve materials and structures can be explored, such as nano molecular sieves, which have a larger specific surface area and faster adsorption rate, and can achieve the same or even higher oxygen production efficiency in a smaller volume. At the same time, optimize the design of the compressor, adopt miniaturized, high-speed and low-energy oil-free compressors, and improve its internal structure and electromagnetic drive system to reduce the volume and weight of components and improve overall performance.
The innovation of battery technology is also an important direction. Traditional lead-acid batteries are large and heavy, while new batteries such as lithium-ion batteries have higher energy density. Further research and development of high-energy-density and lightweight battery materials, such as silicon-based negative electrode materials, can significantly increase battery capacity without increasing battery volume, thereby reducing battery weight and extending battery life. In addition, the battery management system (BMS) is optimized, and an integrated chip design is adopted to reduce the circuit board area and weight of the BMS, improve its precise control of battery charging and discharging, further improve the overall performance of the battery and reduce the weight.
In terms of material selection, lightweight and high-strength materials are used for the shell and internal structural parts of the oxygen concentrator. For example, aviation aluminum alloy or carbon fiber composite materials are used instead of traditional metal materials. Aviation aluminum alloy has a good strength-to-weight ratio and is easy to process and form, which can greatly reduce the weight while ensuring the structural strength of the equipment. Carbon fiber composite materials, with their ultra-high strength and extremely low density, provide great potential for lightweight equipment, and their good corrosion resistance and electromagnetic shielding are also conducive to the stable operation of the equipment in a variety of environments.
In terms of circuit design, a highly integrated circuit design concept is adopted. Integrate multiple functional circuits on a chip or a small circuit board to reduce the number and area of circuit boards, and reduce the complexity and weight of line connections. For example, integrating oxygen concentration sensors, pressure sensors, control circuits, etc. in a dedicated chip module not only improves the reliability and stability of the system, but also significantly reduces the volume and weight of the circuit part.
Heat dissipation design also needs to be optimized to help miniaturization. Traditional heat sinks and fans are bulky, so new heat dissipation technologies can be used, such as liquid cooling or phase change heat dissipation materials. Liquid cooling systems take away heat through miniaturized coolant circulation pipes, while phase change heat dissipation materials use their heat absorption characteristics during the phase change process to achieve efficient heat dissipation inside the device. In addition, the components required for these heat dissipation methods are small in size, which is conducive to the miniaturization of the overall equipment.
In addition, by optimizing the overall layout and structural design of the product, unnecessary space waste and redundant components are reduced. Computer-aided design (CAD) and simulation analysis software are used to accurately layout the various components inside the device, making the gas flow channel, circuit routing, etc. more reasonable and compact, and realizing efficient integration of various functional modules in a limited space, thereby achieving the miniaturization and lightweight goals of the portable oxygen concentrator with battery, providing users with a more convenient and efficient oxygen supply solution.
