Unusually spicy little ionizer - with schematic

The biggest surprise from this unit is the very high ion output from such a tiny transformer and simple pulse circuit. It takes very little power to create a high electrostatic field.

Once again they've felt to need to add the pointless function of an on/off button implemented with a microcontroller. Ionisers are left running all the time, as they use virtually no power and have a continuous ambient cleaning effect on the air through electrostatic dust precipitation.

When the emitters are mounted close to a wall as in this version it does unfortunately create a bit of an ionic short circuit, limiting the dust collection ability, but plugged into an extension on a table would restore that function. When in the vicinity of a wall the ion output can be so vigorous that it creates a slight plasma glow at the tips of the emitter, and will create trace levels of ozone lower than natural outdoor levels.

The X04 component is intriguing. I'll guess that it's a sidac with a voltage less than 150V threshold so that it triggers reliably when running from 120V.
