Definitions

  • the present disclosure relates to air purification, and more particularly, to a negative ionizer air purifier.
  • Air purification is now becoming an important issue in today's world faced with the serious situation of air pollution.
  • air purifiers typically include high-efficiency particulate arrestance (HEPA), activated carbon filtration, low-temperature plasma, photocatalysis, negative ions or anions, etc.
  • HEPA high-efficiency particulate arrestance
  • activated carbon filtration low-temperature plasma
  • photocatalysis negative ions or anions
  • an anion refers to an oxygen ion which gains one or more extra electrons and thus has a net negative charge.
  • Anions can bind with bacteria and dust and kill the bacteria, before they are attracted and settled down to the earth, such that the bacteria and dust can be removed.
  • the negative ionizer air purifier 10 includes a power adapter 11, a high-voltage generator 12, discharge terminals 13 and a positive electrode plate 14.
  • One terminal of the power adapter 11 may connect to the live wire L of the alternating current (AC) mains, while the other terminal may connect to the naught wire N.
  • the power adapter 11 may convert an AC voltage input into a low direct current (DC) voltage, such as a low DC voltage of 12 volts (V).
  • the high-voltage generator 12 may further boost the low DC voltage outputted from the power adapter 11 to a high DC voltage, such as a high DC voltage of 6000V.
  • the positive electrode plate 14 is connected to a second terminal of the high-voltage generator 12.
  • the discharge terminals 13 are connected to a first terminal of the high-voltage generator 12, and may release electrons outward when a high DC voltage is applied.
  • a virtual earth is applied to the positive electrode plate 14
  • an excess of positive charge may accumulate on the positive electrode plate 14 when the discharge terminals 13 release electrons outward, due to charge balance.
  • the positive electrode plate 14 may be saturated with positive charge, which may lower the speed of releasing electrons by the discharge terminals 13, resulting in a substantial decline in the efficiency of the negative ionizer air purifier 10.
  • the prior art negative ionizer air purifier also has the following shortcomings.
  • the air near the front of the discharge terminals 13 is static in absence of external forces. Due to the poor airflow, the electrons released from the discharge terminals 13 cannot be effectively captured by the air beyond a very limited range, which may also reduce the efficiency of the negative ionizer air purifier.
  • the discharge terminals 13 are encased inside the housing, and the electrons released by the discharge terminals 13 may decomposite a portion of the carbon dioxide in the atmosphere into carbon, which may attach to the interior of the housing and thus may be very difficult to clean. Since carbon has a certain electrical conductivity and the housing between two discharge terminals 13 is continuous, a short circuit is prone to occur between them.
  • the prior art negative ionizer air purifiers rely solely on the discharge terminals 13 to release electrons, the concentration of the electrons is relatively low, such that the concentration of the anions produced is very limited, which may also accounts for the low efficiency of the negative ionizer air purifiers.

  • the number of the passages may not be the same as that of the discharge terminals, and the specific positions of the passages can be set based on actual requirements.
  • the speed of the airflow produced by the fan is adjustable. The greater the voltage at the discharge terminals 631 and 632, the more the total electrons released from the discharge terminals, and the higher the concentration of the anions in the surrounding air.
  • the speed of the airflow produced by the fan 64 is larger than the speed of the saturated anions being produced in the surrounding air (in other words, the saturation speed).
  • the speed of the airflow surrounding the discharge terminals 631 and 632 can be accelerated, such that more air, which is not negatively charged, can fill in the working area in the vicinity of the discharge terminals 631 and 632, and the surrounding air that is already negatively charged can be driven out as quickly as possible, thus the efficiency of the negative ionizer air purifier can be significantly improved.
  • the air in the vicinity of the discharge terminals cannot be easily replaced, in which case however high the voltage at the discharge terminals is or however large the number of the discharge terminals is, the anion-generation efficiency will not be increased too much when the ionization of the air within the working area reaches its saturation point-since the air is not replaced in time and the working area of multiple discharge terminals may at least partly overlap.
  • the anion-generation efficiency has little to do with the magnitude of power, but has much to do with the voltage at the discharge terminals.
  • the anion-generation efficiency can be significantly improved.
  • FIG. 10 a schematic diagram of an eighth example negative ionizer air purifier according to the disclosure is shown.
  • the negative ionizer air purifier 70 is provided with two energy rings at the periphery of the discharge terminal 73.
  • the two energy rings are typically concentric with the discharge terminal 73.
  • the inner ring is an electron-enhancement ring 74
  • the outer ring is an electron-control ring 75.
  • the electron-enhancement ring 74 can release electrons outward when a changing electric field is produced by the discharge terminal 73.
  • the electron-enhancement ring 74 is of a suitable piezoelectric ceramic material, which may create a tendency of volume expansion, due to piezoelectric effect, within the changing electric field produced by the discharge terminal 73.
  • the outer electron-control ring 75 is of a non-piezoelectric material, whose shape will not be affected by the electric field.
  • the outer electron-control ring 75 can prevent the volume expansion of the electron-enhancement ring 74.
  • the electron-enhancement ring 74 will release electrons under a combination of the pressure from the electron-control ring 75 and the high electric field.
  • the high electric field may be produced by the voltage fluctuation at the discharge terminal 73, and can also be produced by the pulse voltage at the discharge terminal 73. Since energy rings are further added in addition to the discharge terminals, they can take full advantage of the high electric field produced by the discharge terminals to release electrons. Therefore, the anion concentration can be increased and the efficiency of the negative ionizer air purifier 70 can be further improved.
  • advantages of the present disclosure may follow: by providing in the housing the at least two receiving holes corresponding to the discharge terminals each disposed in the corresponding receiving hole, and hollowing out the housing at the periphery of each discharge terminal and at the part between the discharge terminals, the discharge terminals can be effectively electrically separated from each other, and thus the short circuit caused by the carbon, produced from the decomposition of the carbon dioxide in the surrounding air and attached on the surface of the housing, can be efficiently avoided.
