Laser blockage......?

my laser was clogged with dust while drawing and I made the spare air pump this way, do you think it will be a solution?

You need to increase the pressure in the nozzle so that it has a higher positive pressure. That way, smoke and other material will not be able to go into the nozzle.

when the air pressure is increased, it makes the engraving deeper, but I tried it so that nothing happens to the laser head

You can try like this and I guess it will help. Though, the technical correct solution would be to use air assist all the time and never turn it off. That’s the only 100%-protection for the lens/nozzle.
