[0002] In small-scale commercial applications, such as wastewater treatment in county-level slaughterhouses, fruit and vegetable sterilization in hotel kitchens, and small-scale aquaculture, there is a specific need for a continuous, stable, and low-cost oxygen supply. However, traditional oxygen supply methods face many limitations in these scenarios: cryogenically produced liquid oxygen needs to be stored in expensive Dewar flasks, and there are safety hazards associated with transportation and storage; high-pressure oxygen cylinders offer intermittent supply, are cumbersome to replace, and have high overall operating costs. These traditional methods fail to meet the dual requirements of economy and convenience for small-scale commercial applications.

Therefore, the market needs a small-scale commercial oxygen generator that is miniaturized, low-cost, highly reliable, and capable of continuous and stable operation to fill the market gap left by existing technologies.

[0030] To facilitate understanding of the above-mentioned technical solutions of this utility model, the following detailed description of the above-mentioned technical solutions of this utility model is provided through specific usage methods.

[0031] In practical use, the core of the small commercial oxygen generator according to this utility model is to highly integrate the gas source device 2, air pretreatment system 3, air buffer tank 4, adsorber assembly 5, oxygen tank 6 and control assembly 7 into a box 1, forming a compact and mobile integrated device.

[0032] In use, the operator turns on the equipment via a one-button start switch on the control component 7. The control component 7 then sends commands to each component to initiate the entire oxygen production process. The air source device 2 begins operation. In this embodiment, the air source device 2 is preferably a permanent magnet variable frequency scroll compressor, which can draw in and compress ambient air in a low-noise and low-energy manner, providing a stable air source. The compressed air is then transported to the air pretreatment system 3 through pipelines.

[0033] In the air pretreatment system 3, compressed air first passes through a filter to remove oil, water, and solid particulate impurities; then it enters a dryer, which in this embodiment is preferably an adsorption dryer, used to deeply remove moisture from the air to ensure that the output compressed air is dry and clean. The pretreated gas enters the air buffer tank 4 through a pipeline. The air buffer tank 4 acts as a buffer container, storing and stabilizing the airflow, effectively mitigating system pressure fluctuations and short-term air demand.

[0034] Subsequently, the stabilized clean compressed air enters the adsorber assembly 5 from the air buffer tank 4. The adsorber assembly 5 is filled with molecular sieves and, using the pressure swing adsorption principle under program control, selectively adsorbs components such as nitrogen from the air, thereby enriching and passing oxygen. Next, high-purity oxygen is produced from the adsorber assembly 5 and piped into the oxygen tank 6. This oxygen tank 6, as a process tank, stores and stabilizes the airflow pressure, effectively mitigating system pressure fluctuations and ensuring a stable and continuous output of oxygen. Finally, it is transported through pipelines to the oxygen outlet for use by downstream equipment. Furthermore, an oxygen monitoring sensor is installed at the oxygen outlet to monitor oxygen concentration, pressure, and other parameters in real time, feeding the data back to the control assembly 7. Operators can use this to remotely monitor and ensure stable and reliable oxygen production quality.

[0035] The entire unit is mounted on movable casters at the bottom of the housing 1, facilitating flexible movement and deployment in various small commercial settings. Through the coordinated operation of the aforementioned components, this oxygen generator achieves fully automated and continuous operation from air compression and purification to oxygen separation, meeting the needs of small commercial applications with high requirements for oxygen purity, equipment stability, and operating costs.

[0036] In summary, by employing the above-mentioned technical solution of this utility model, and by adopting a highly integrated overall design and compactly arranging key functional modules within the housing, the equipment structure is simplified and the floor space is significantly reduced. By using a high-efficiency and energy-saving scroll compressor as the air source and matching it with an optimized air pretreatment and adsorption process, the energy consumption and noise of the equipment during operation are effectively reduced, thereby achieving the goals of economical and quiet operation. By introducing a stable and reliable one-button automated control system and strengthening the durability of key components, the equipment can achieve stable oxygen supply for long periods of time without interruption, and is easy to operate and maintain. Ultimately, through the above comprehensive optimization, this oxygen generator successfully provides a stable and reliable oxygen supply solution for small-scale commercial applications with lower manufacturing and operating costs, perfectly meeting the specific needs of the market.
