Detailed Description
First embodiment
Referring to fig. 1, fig. 1 is a schematic structural diagram of an ionizer of the present invention, including: a power supply 101, a first connection line 102, a second connection line 103, and an ion generating part 104.
Referring to fig. 2 and 3, fig. 2 is a schematic structural diagram of a power supply 101 according to a first embodiment of the invention, and fig. 3 is a schematic circuit diagram of the power supply 101 according to the first embodiment of the invention; the power supply 101 includes a high voltage output circuit 111, a magnetic core YA1, a power supply first connection port 42a, and a power supply second connection port 43 a.
The high-voltage output circuit 111 comprises a transformer T1 and a voltage doubling circuit connected with a secondary winding of the transformer T1, wherein the voltage doubling circuit comprises a diode D1, a diode D2, a diode D3, a diode D4, a capacitor C1, a capacitor C2, a capacitor C3, a capacitor C4, an output port Vo and a ground port GND;
one end of a capacitor C1 is connected to the dotted terminal of the secondary winding of transformer T1, the other end of a capacitor C1 is connected to the anode of diode D1, the cathode of diode D2 and one end of a capacitor C3, the other end of a capacitor C3 is connected to the anode of diode D3 and the cathode of diode D4, the anode of diode D4 is connected to one end of capacitor C4, the connection point of the diode D4 is used as an output port Vo, the other end of a capacitor C4 is connected to the anode of diode D2, the cathode of diode D3 and one end of capacitor C2, the other end of a capacitor C2 is connected to the cathode of diode D1 and the dotted terminal of the secondary winding of transformer T1, and the connection point thereof is used as a ground port GND.
The output port Vo of the high voltage output circuit 111 is connected to the second connection port 43a of the power supply, the ground port GND of the high voltage output circuit is connected to one end of the magnetic core YA1, and the other end of the magnetic core YA1 is connected to the first connection port 42a of the power supply.
The power supply first connection port 42a is connected to a ground electrode provided in the ion generating part 104 via a second connection line 103, and the power supply second connection port 43a is connected to an emitter electrode provided in the ion generating part via a first connection line 102.
The working principle of the embodiment is as follows:
the high voltage output circuit 111 outputs a negative high voltage, which is applied between the output port Vo and the ground port GND, the output port Vo is a negative high voltage, and the ground port GND is a zero position. The output port Vo is directly connected to the second connection port 43a of the power supply, and the ground port GND is connected to the first connection port 42a of the power supply after passing through the magnetic core YA1, that is, the magnetic core YA1 is connected in series between the high voltage output circuit 111 and the ion generating element 104, and the maximum current Imax that can flow into the ion generating element 104 has the relationship:
where Uo is the output voltage of the high voltage output circuit 111. R is the equivalent impedance of the core YA 1.
As described above, the maximum current Imax flowing into the ion generating member 104 can be controlled by adjusting the equivalent impedance of the magnetic core YA1, and the intensity of corona in the ion generating member 104 can be controlled. Because the magnetic core is made of ferrite or other high-impedance materials, the equivalent impedance R of the magnetic core is very large, the maximum current Imax can be well limited, and the ozone inhibition effect is obvious.
According to the mechanism of corona discharge, the more intense the corona discharge, the more ozone content is generated, and the excessive ozone is generated to be not beneficial to human health. Furthermore, when the ion generating member 104 reaches the upper limit of the corona discharge level, the glow discharge and the spark discharge start to progress, and the ion generating condition is destroyed, so that the ion generating member 104 cannot stably generate negative ions.
Therefore, the equivalent impedance of the magnetic core YA1 can be set according to the requirement, so that various ionizers with different ozone concentrations can be formed, and the requirements of different consumers can be met; in addition, by providing the magnetic core YA1 with a larger impedance value, the maximum current Imax of the ion generating part 104 is reduced, and further, the ozone concentration is reduced, ensuring that the ion generating part 104 stably operates in the corona discharge state.
