1. The ioniser contains a thermoionic cathode and an anode. It is characterised in that the first cathode (6) grip (5) is located at the outlet (4) of the first tube (3). The cathode (6) is located inside the second tube (8). The second cathode (6) grip (9) is located in the third tube (10). All the three tubes (3, 8, 10) are made of a conductive material and located in the insulating shield (1), equipped with the air inlet (2). The diameter of the third tube (10) is larger than the diameter of the second tube (8), while the second tube (8) is larger than the diameter of the first tube (3). |
