Description

Negative oxygen ion generator suitable for flowerpot Technical Field The utility model belongs to the technical field of negative oxygen ion generators, and particularly relates to a negative oxygen ion generator suitable for a flowerpot. Background Negative oxygen ions (Negative Oxygen Ion) refer to oxygen molecules (O 2-) carrying excess electrons and exhibiting electronegativity, the generation principle of which is based on the phenomenon of air ionization 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 3-6 kV), negative oxygen ions are formed by combining with free electrons. According to the air anion concentration grade standard issued by the Chinese disease prevention and control center, when the anion concentration in the environment reaches 2X 10 3/cm 3, the comfort of the human body can be improved, and the air anion concentration grade standard has remarkable medical care effect when exceeding 5X 10 4/cm 3. The traditional negative oxygen ion generator mainly adopts corona discharge technology and consists of a high-voltage generation module, an electrode array and an ion diffusion device. The high voltage generation module converts commercial power into direct current high voltage, and the surrounding air is ionized by generating a strong electric field through the tip electrode. The equipment has wide application in the fields of industrial purification, medical care and the like, but has the inherent defect that the ion diffusion range of commercial products is limited to 10-15m 3 space, and the requirement of the open living space of modern families is difficult to meet. Experimental data show that the negative ion concentration attenuation rate of the conventional generator reaches more than 65% after the conventional generator works in a space of 40m <2 > for 1 hour. The existing products mostly adopt independent box structures, and obvious offensive sense exists between the existing products and interior decoration. In order to improve the space adaptability of the traditional generator, innovative designs for combining the negative ion generator with the flowerpot are appeared in recent years. The product promotes ion diffusion by utilizing the plant transpiration effect through arranging an ionization module at the bottom of a plant pot. However, the technical bottleneck is that most products simply place the generator at the bottom of the flowerpot, and no special diversion structure is arranged. Particle Image Velocimetry (PIV) experiments show that such designs result in more than 60% of negative ions forming vortex retention at the bottom of the basin, with an effective diffusivity of less than 20%. The traditional device mostly adopts a single row of needle-shaped electrodes, and the electric field distribution is uneven. Finite element analysis showed that the field strength 15mm from the electrode decayed to 18% of the central region, resulting in too small an ionization region. Disclosure of utility model In view of the above, the negative oxygen ion generator suitable for the flowerpot provided by the utility model solves the problems that the traditional flowerpot integrated negative oxygen ion generator has low ionization efficiency and cannot stably maintain effective concentration. The utility model is realized in the following way: the utility model provides a negative oxygen ion generator suitable for a flowerpot, which comprises the following components: A flowerpot base, the inside of which forms a containing chamber; The negative oxygen ion generator module is fixedly arranged in the accommodating cavity; The ventilation grid is covered on the top of the flowerpot base and is communicated with the accommodating cavity; The flow guiding structure is arranged above the negative oxygen ion generator module and forms an airflow channel with the ventilation grid; The power supply module is embedded in the side wall of the flowerpot base and is electrically connected with the negative oxygen ion generator module; and the control module is integrated on the front side panel of the flowerpot base and comprises an operation switch. The power supply module comprises a detachable lithium battery and a USB-C charging interface, and the detachable lithium battery and the USB-C charging interface are connected in parallel through a power management circuit. The detachable lithium battery of the power supply module is of a fan-shaped structure, sliding guide rails are arranged on two sides of the detachable lithium battery and are matched with guide grooves on the side wall of the base, and a waterproof rubber plug of the USB-C charging interface and the outer wall of the flowerpot base form a labyrinth sealing structure.
