It should be noted that, as long as there is no conflict, the embodiments and the features of the embodiments of the present invention may be combined with each other, and the technical solutions formed are within the scope of the present invention.
Example one
In order to solve the above technical problems in the prior art, an embodiment of the present invention provides an ion generating circuit.
Fig. 1 is a schematic structural diagram of an embodiment of an ion generating circuit of the present invention, and as shown in fig. 1, the ion generating circuit 1 of the present embodiment includes an oscillation module 10, a step-up transformer T, a discharging module 11, a voltage-doubling rectifying module 12, a first discharging electrode interface 13, and a second discharging electrode interface 14; the booster transformer T comprises a first primary side T1, a second primary side T2 and a secondary side T3; the first discharge electrode interface 13 and the second discharge electrode interface 14 are two discharge electrode interfaces with opposite electrodes.
In a specific implementation process, the control end of the oscillation module 10 is electrically connected to the first end of the first primary side T1, and the second end of the first primary side T1 is electrically connected to the input power supply 2, so as to form an oscillation control loop; the first end of the oscillating module 10 is electrically connected with the first end of the second primary side T2; the second end of the oscillation module 10 is electrically connected to the ground GND; the second end of the second primary side T2 is electrically connected with the input power supply 2 to form an oscillation output loop; a first end of the secondary side T3 is electrically connected to the input end of the discharge module 11 and a first end of the voltage-doubling rectifying module 12, and a second end of the secondary side T3 is electrically connected to a second end of the voltage-doubling rectifying module 12; the output end of the discharging module 11 is electrically connected with the first discharging electrode interface 13, and the third end of the voltage-doubling rectifying module 12 is electrically connected with the second discharging electrode interface 14.
In this embodiment, the oscillation control circuit periodically controls the oscillation module 10 to be turned on by using the first dc voltage input by the input power source 2, so that the first dc voltage input by the input power source 2 outputs the ac voltage through the oscillation output circuit. The step-up transformer T steps up the alternating voltage and then rectifies the alternating voltage through the voltage doubling rectifier module 12 to obtain a second direct voltage, the second direct voltage is output to the first discharge electrode interface 13 through the second end of the voltage doubling rectifier module 12 and the discharge module 11, the second direct voltage is output to the second discharge electrode interface 14 through the third end of the voltage doubling rectifier module 12, and therefore discharging is performed between the first discharge electrode 3 connected with the first discharge electrode interface 13 and the second discharge electrode 4 connected with the second discharge electrode interface 14.
Specifically, in a first phase in which the oscillation control loop converts the input first direct voltage into an alternating voltage: the first dc voltage output by the input power supply 2 is applied to the control terminal of the oscillation module 10 via the first primary side T1 of the step-up transformer T, and the oscillation module 10 is turned on. Wherein, the first direct current voltage may be 12V direct current voltage.
In a second phase of the oscillation control loop converting the input first direct voltage into an alternating voltage: the first dc voltage output by the input power supply 2 enters a voltage output state through an oscillation output loop formed by the second primary side T2 of the step-up transformer T and the oscillation module 10, converts the first dc voltage into an ac voltage, and outputs the ac voltage to the secondary side T3 of the step-up transformer T. As the current increases, the oscillating module 10 tends to saturate, the current drops, the oscillating module 10 turns off, and the first phase is re-entered.
In the first output stage of the step-up transformer T, the step-up transformer T can complete the first charging of the voltage-doubling rectifying module 12 after stepping up the input ac voltage and rectifying by the voltage-doubling rectifying module 12; in the second output stage of the step-up transformer T, the step-up transformer T steps up the input ac voltage, and then rectifies the ac voltage by the voltage-doubler rectifier module 12, so as to obtain a second dc voltage by charging the voltage-doubler rectifier module 12 for the second time together with the first charging voltage of the voltage-doubler rectifier module 12, the second dc voltage is output to the first discharge electrode interface 13 through the second end of the voltage-doubler rectifier module 12 and the discharge module 11, and the second dc voltage is output to the second discharge electrode interface 14 through the third end of the voltage-doubler rectifier module 12, so as to discharge between the first discharge electrode 3 connected to the first discharge electrode interface 13 and the second discharge electrode 4 connected to the second discharge electrode interface 14. The peak value range of the voltage U1 obtained by boosting the input ac voltage by the step-up transformer T may be, but is not limited to 1800 to 2000 VAC. The voltage obtained by boosting the input ac voltage by the step-up transformer T may be 2 × U1 after voltage doubler rectification.
In the ion generating circuit 1 of this embodiment, since the voltage boosted by the step-up transformer T is rectified by the voltage-doubling rectifying module, even when the voltage boosted by the step-up transformer T is small, a high dc voltage can be obtained to generate many ions, thereby reducing the volume of the step-up transformer T and further reducing the volume of the ion generator. At the same time, the cost of the ionizer is reduced.
