Description

Technical Field

[0001] This application relates to the technical field of ion generators, and particularly to an ion generator and an air purifier based on variable power supply. Background Art

[0002] The working principle of a negative oxygen ion generator mainly involves processing the input direct current or alternating current through specific circuits (such as an electromagnetic interference filter (EMI) processing circuit and a lightning protection circuit), and then boosting it to an alternating high voltage through circuits such as a pulse circuit, overvoltage and current limiting, and high and low voltage isolation. Then, after rectifying and filtering through special-grade electronic materials, a pure direct current negative high voltage is obtained. This direct current negative high voltage is connected to the discharge tip, and a high corona is generated using the tip direct current high voltage, and a large number of electrons are released at high speed. These electrons cannot exist in the air for a long time (the lifespan of existing electrons is only in the nanosecond range), and will immediately be captured by oxygen molecules (O2) in the air, thereby generating air negative ions.

[0003] Negative oxygen ion generators can be classified into two categories according to their generation principles: electric air negative ion generators and water air negative ion generators. Electric air negative ion generators use a high-voltage electric field to ionize the nearby air through corona discharge at the tip of the electrode needle to generate negative ions. Water air negative ion generators utilize the Lerner effect (or waterfall effect), that is, water is sprayed from the nozzle of the generator, and after being impacted and crushed into charged mist-like particles, it combines with neutral molecules in the air to form water air negative ions.

[0004] In addition, the ion generator can also release huge energy instantaneously through the neutralization of positive and negative charges by positive and negative ions in the air, thereby causing changes in the bacterial structure and energy transfer around it, thus achieving a bactericidal effect. At the same time, the ion generator can also efficiently decompose TVOC such as formaldehyde, benzene series, ammonia, and other gaseous organic volatiles, thereby eliminating odors.

[0005] Therefore, the negative ion air purifier based on the above negative oxygen ion generator has now become a well-known product in the air purification market. However, the accompanying problem is that this negative oxygen ion generator will cause the black wall problem. The reason is that under the action of the high-voltage electric field, the electrostatic distribution has a certain range, including the electrostatic field existing around the air purifier, especially behind it. Therefore, in addition to inside the air purifier, some dust will also adhere to the wall, so the room wall will re-absorb dust, resulting in the formation of a black wall. Therefore, an ion generator and an air purifier that solve the black wall problem are needed.
