AI Technical Summary
Most existing low-temperature plasma generators lack filtration function. When gas enters the generator, particles and water vapor are easily doped, resulting in particles consolidation inside the generator and hindering the emission of high-energy electrons. Invasion of water vapor will cause erosion and damage to the equipment.
A low-temperature plasma generator is designed to transport gas to the inside of the filter box under the action of an air pump, and filter particles and water vapor in the gas under the action of filter materials (such as non-woven fabrics). The filtered gas enters the plasma. The generator is converted into a plasma state and then shot out by the plasma nozzle.
It effectively solves the filtration problem of particles and water vapor in the gas, prevents particle consolidation and water vapor erosion, extends the service life of the equipment and ensures the normal output of high-energy electrons.

Technical Field
