Description

Technical Field

[0001] This utility model belongs to the technical field of negative oxygen ion generators, specifically, it relates to a negative oxygen ion generator suitable for flower pots. Background Technology

[0002] Negative oxygen ions (O2) are oxygen molecules (O2) that carry excess electrons and have a negative charge. - The generation principle is based on the air ionization phenomenon under the action of a high-voltage electric field. When neutral oxygen molecules in the air lose electrons under the action of high voltage (usually 3-6kV), they combine with free electrons to form negative oxygen ions. According to the "Air Negative Ion Concentration Level Standard" issued by the Chinese Center for Disease Control and Prevention, when the concentration of negative ions in the environment reaches 2×10⁻⁶, it is considered a negative oxygen ion. 3 pcs / cm 3 It can improve human comfort, exceeding 5×10 4 pcs / cm 3 It has significant health benefits.

[0003] Traditional negative ion generators primarily employ corona discharge technology, consisting of a high-voltage generating module, an electrode array, and an ion diffusion device. The high-voltage generating module converts mains power into DC high voltage, generating a strong electric field through pointed electrodes to ionize the surrounding air. While such devices are widely used in industrial purification and healthcare, they suffer from inherent limitations: the ion diffusion range of commercially available products is mostly limited to 10-15 meters. 3 The space is insufficient to meet the needs of modern open-plan living spaces. Experimental data shows that after one hour of operation in a 40㎡ space, the negative ion concentration of a conventional generator decreases by more than 65%. Existing products mostly adopt a freestanding cabinet structure, which looks obviously out of place with the interior decoration.

[0004] To improve the spatial adaptability of traditional ion generators, innovative designs combining negative ion generators with flowerpots have emerged in recent years. These products utilize ionization modules placed at the bottom of the plant pot, leveraging plant transpiration to promote ion diffusion. However, the following technical bottlenecks exist: most products simply place the generator at the bottom of the flowerpot without a dedicated flow-guiding structure. Particle image velocimetry (PIV) experiments show that this design causes over 60% of negative ions to stagnate at the bottom of the pot, resulting in an effective diffusion rate of less than 20%. Traditional devices often use a single row of needle-like electrodes, leading to uneven electric field distribution. Finite element analysis shows that the electric field strength at 15mm from the electrode decreases to 18% of that in the central region, resulting in an excessively small ionization area.
