The method for purifying the air with the above-mentioned plant potted air purifier is specifically implemented according to the following steps:

Step 1, plant the potted ornamental plants in the inner pot 10 of the potted container 4 according to the conventional method, and water until the culture medium is moist;

Step 2, put the inner basin 10 into the insulating outer basin 12, keep a certain space distance between the inner basin 10 and the outer basin 12, and connect the side adsorption electrode plate 14 on the side wall of the outer basin 12 with a wire and a ground wire.

Step 7, when the person contacts the plant, the protection module 7 installed on the base cuts off the power supply, and restores the power supply when leaving, so as to avoid the occurrence of electric shock.

The principle of the present invention is that the plants grown in the inner basin culture medium of the cultivation container and the moist culture medium are good conductors, and the air holes densely covered on the side wall of the inner basin have not only ensured the communication between the gas inside the culture medium and the outside atmosphere, In addition, when the plant root system grows, it contacts the air through the air holes on the side wall to stop the growth, forcing the rear of the root tip to continuously germinate new roots, and obtain a well-developed root system, thereby effectively promoting the growth of the plant root system. When the 220V commercial power is converted into the signal required by the processing module through the power module, the signal will generate a periodic voltage signal that matches the potential fluctuation of the potted plant cells through the processing module, and the latter will be loaded into the culture medium through the trigger module Under the action of the voltage signal, the plant root system and leaf cell membrane potentials planted in the culture medium undergo potential coupling resonance, and the respiratory metabolism of root cells and photosynthesis of leaf cells are periodically accelerated. During this process, the root cell respiratory electron transport chain and the leaf cell photosynthetic electron transport chain produce a large number of redundant electrons, which are mainly distributed in the root tip, leaf edge and leaf tip, resulting in periodic tip discharges at the root tip and leaf tip. , continuously generating ion wind. The ion wind generated by the root tip flows outward through the air channel between the inner pot and the outer pot, and the ion wind generated by the leaf tip is directly emitted to the air, and the two together increase the ion concentration around the potted plant. The high concentration of ions around the potted plants combine with the pollutants in the air to form charged particles, which are directional adsorbed on the adsorption electrode plates located around the potted plants through the force of the electric field, avoiding the impact of the charged pollutant particles on the vicinity of the plants. Contamination of walls, objects and floors. Under the action of the continuous ion wind produced by the potted plants, the pollutants in the air near the potted plants are firstly purified, and the polluted air farther away continues to spread to the vicinity of the potted plants and is purified successively. When people are about to touch the leaves of potted plants, the protection module installed in the substrate automatically sends out a signal to cut off the circuit of the power module in time, and automatically restores the circuit when leaving the plant at a certain distance, avoiding the occurrence of discharge between plants and people. The hollow air-permeable anti-shock protection cover fixed on the outer surface of the adsorption electrode plate avoids electric shock when people touch the adsorption electrode plate.

Example

The container and the pedestal of cultivated plants are two parts as shown in Figure 1 among the present embodiment, and the inner pot and the outer pot in the cultivation container are all made of cylindrical insulating plastics, and the diameter of the inner pot is 15cm, and the diameter of the outer pot is 17cm. The gap between the inner and outer basins is 1cm, and the height of the inner and outer basins is 20cm. The side wall of the inner basin is densely distributed with rectangular ventilation holes. The outer surface of the outer basin is surrounded by a conductive aluminum foil layer as a side adsorption electrode plate, and a hollowed-out air-permeable plastic material is installed outside the side electrode plate. Ring protection cover against electric shock.

Fill the inner basin with ordinary soil, plant the aloe vera with a plant height of about 15cm into the soil, and add appropriate amount of water to make the soil moist. 15cm above the aloe blade, the aluminum plate with a thickness of 1mm and a radius of 20cm is fixed as the upper adsorption electrode plate by a bracket, and a hollow air-permeable anti-shock protective cover of plastic material is installed on both sides of the upper adsorption electrode plate.

In a closed plexiglass experiment box with a size of 1.5m×1.5m×1.5m, an electronic cigarette lighter is used to fill the dense smoke, and a small fan is used to disperse the smoke to distribute the smoke evenly. The PM2.5 concentration in the test box reached 260μg/m ³ , compared with the national air quality secondary standard of 75μg/m ³ , the PM2.5 in the box seriously exceeded the standard at this time, reaching the level of severe pollution.

The potted plant air purifier of the present invention is placed in the center of the experiment box, and the processing module generates a matching extremely low frequency periodic voltage signal according to the characteristic that the center frequency of the aloe cell potential fluctuation spectrum is extremely low frequency. After being treated with the potted plant air purifier of the present invention for 40 minutes, the concentration of PM2.5 in the airtight test chamber was detected to be reduced to 0.38 μg/m ³ by using the American DC1700 Dylos air quality detector. At the same time, no ozone concentration was detected in the test chamber using a pump-suction trace ozone detector with a resolution of 0.01ppm.

A comparative experiment with an air purifier of a certain foreign brand worth 4,000 yuan that is currently popular in the market shows that the concentration of PM2.5 is reduced to 3.45 μg·m ^-3 after the air purifier of this brand is treated for the same time under the same conditions. It shows that the purification effect of the potted plant air purifier of the present invention is better than the purification level of mainstream air purifiers currently on the market.

In a 14m ² ordinary home with doors and windows closed in winter smog, after using the smart potted plant air purifier continuously for several days, a large number of ultrafine pollutant particles can be seen on the upper adsorption electrode plate and the side adsorption electrode plate, while There was no obvious pollutant deposition phenomenon in the potted plants and their surroundings. The concentration of PM2.5 in the indoor air detected by the American DC1700 Dylos air quality detector is significantly lower than that of the outdoor, and the effect of purifying the air is very obvious.

The plant air purifier has been working continuously for 3 years, and the potted aloe used grows normally without any damage to the aloe.
