Technical Field

The present application relates to the field of plasma therapy technology, and in particular to an anti-interference output power adjustment module for plasma therapy equipment.

Background Art

Plasma skin therapy is a medical anti-aging treatment for the skin, used to reduce wrinkles and remove growths. During plasma treatment, a probe is placed close to the skin for tip discharge, and the released plasma energy leaves a carbonized point on the skin surface. The larger the treatment area, the more carbonized points are needed to form a dot matrix. During tip discharge, the discharge power will affect the size and distribution of the carbonized points, and will also affect the treatment effect. Precise regulation of power is one of the difficulties in equipment design. It should be pointed out that during plasma discharge, strong electromagnetic interference will be generated, which may interfere with the ordinary power regulation circuit itself, so a more interference-resistant power regulation method is needed.

The oscillation circuit is a Royer oscillation circuit, and the output end of the oscillation circuit is connected to an external treatment device.

Working principle: When using plasma treatment, you need to use treatment equipment such as a treatment handle.

This mechanical adjustment method can avoid external electromagnetic interference, has higher reliability, and is suitable for occasions with large electromagnetic interference.
