At 22;000 feet and climbing I noticed a slight burning smell. I turned around to see if Flight attendant was using the oven. He was not near the oven. I turned to Captain and queried him about the smell. He did not immediately smell it so I opened my gasper. Immediately smoke started filling the cockpit. I closed the gasper.The Captain and I donned our oxygen masks. I turned to look at cabin and it was smoke filled. Flight Attendant (FA) had already taken notice. And was taking appropriate FA steps. Communications between pilots and controllers is extremely difficult with oxygen masks. I stayed pilot flying and used COMM 2 to call Center. I asked for nearest suitable airport. I'm not sure Center's response but knowing the Coastal area very well; I spotted an airport immediately and headed that direction informing ATC. The Captain started the appropriate emergency checklists but much attention was given priority to getting the plane safely on the ground. He started helping me again with radios. We were queried by approach and confirmed emergency assistance of fire and rescue 15 miles out. While smoke had seemed to start dissipating; we were not taking chances on it getting worse once the engines spooled back up.Once on the ground; we assessed that smoke was no longer entering the cockpit so we cleared the runway as not to be a hazard. We taxied to a nearby FBO; shut down the airplane entirely. I immediately exited the airplane. Not detecting any immediate threat; I stated opening all Cargo and equipment areas for inspection. FBO lineman noted later that he did smell odor from cabin after we opened the door.About 10 minutes later Fire and rescue personnel from town showed arrived at airplane using thermal imaging to scan for any problems. Two Company maintenance personnel also happened to be on scene and helped the Fire Department (FD) safely perform its inspection. After 15 more minutes; the plane was determined safe and the FD left.  During this same time; [the captain] had been contacting appropriate people at the company.More emphasis should be given for maintaining ATC and crew communications during an emergency with O2 masks in use. It is very difficult; if not nearly impossible if noises were any louder in cockpit. Airport database needs to be updated.

A DA-2000 climbing through FL220 developed a burning smell and ejecting smoke from a gasper which was then closed. Oxygen masks were donned; a diversion began and the checklists were completed. After landing no hot spots were seen by emergency personnel.
