The turns ratio on the control line in this embodiment is 210/140/70.
The plasma generator provided in the present embodiment further includes: and an output protection component.
The output protection component is arranged outside the oscillator and used for resisting high voltage on the oscillator inside.
This embodiment still provides an environmental protection fan, includes: a fan and a controllable positive and negative plasma generator as described in the above embodiments.
The controllable positive and negative plasma generator is positioned on the air duct of the fan.
In the embodiment, the rear end of an input power supply in the generator is designed into a controllable voltage-multiplying line, and the primary voltage input to the oscillator can be adjusted according to requirements through the first change-over switch K1.
The working principle diagram of this power supply voltage doubling is shown in fig. 2: in the figure: vcc is an input voltage, and is 12V in this embodiment. R1, R2 and C1 form an oscillation loop. Pin 3 is the pulse oscillation output. Through D1 and D2 rectification voltage doubling, a voltage close to 24V can be obtained at the V output end.
The output end of the oscillator is provided with 2 controllable devices which are respectively a second change-over switch K2 and a third change-over switch K3 and respectively control a positive voltage output value and a negative voltage output value, thereby controlling the emission quantity of positive and negative ions.
In this embodiment, the input working voltage is dc 12V, the number of turns of the primary winding of the oscillator is 25/50, the number of turns of the secondary winding is 3450, and a control line tap is tapped at 2500 turns. The turn ratio was 210/140/70 (optional). The control is performed by K2 and K3.
The working principle of the ionizer in this embodiment is:

For efficient sterilization, a higher number of positive and negative ions need to be emitted. When a higher voltage is required at the output end, for example, 5000V is required, the ionizer in this embodiment gives a control signal to the variable voltage control module, so that a voltage-multiplying voltage of 24V is output to the primary coil end of the oscillator.

The floating dust in the air can generate a coagulation phenomenon after encountering polar ions, the mass of particles is increased, the particles are accelerated to settle, and the charged particles can be attached to a grounding electrode when encountering fields such as the ground, the surface and the like with zero potential in the air moving process, so that the floating dust is converted into dust fall, and the inhalable particles in the air are reduced.
Because the oxidizing power of the ionic oxygen molecules with positive and negative polarities is greater than that of neutral oxygen molecules and the momentum of the positive and negative polarities in the mutual attraction process greatly improves the oxidizing and decomposing power of the ionic oxygen molecules with positive and negative polarities, the effect of efficiently decomposing TVOC (volatile organic compound) such as formaldehyde, benzene series, ammonia and the like and other gaseous organic volatile matters can be achieved, and the peculiar smell is eliminated.
