Abstract
A hot air generator comprising a handle (12), an elongated nozzle (14), flame generating means (6), a venturi (4), a gas conduit (162) intended to bring a combustible gas into the elongated nozzle (14) and at the flame generating means (6), an air conduit (164) intended for bringing compressed air into the elongated nozzle (14) and downstream from the venturi; characterized in that the generator further comprises a servocontrolled pressure regulator (2) controlling a gas pressure (Pd.g) in the gas conduit (162) depending on an air pressure (Pd.a) in the air conduit (164).
Claims15
A portable hot air generator comprising:
- a handle comprising an igniter;
- an elongated nozzle bound to the handle comprising an outlet end for ejecting hot air;
- a flame generator inside the elongated nozzle;
- a venturi upstream from the flame generator, formed on the elongated nozzle;
- a gas conduit passing through the handle to bring a combustible gas into the elongated nozzle and at the flame generator, the gas conduit extending through the handle and up to the flame generator;
- an air conduit passing through the handle to bring compressed air into the elongated nozzle and upstream from the venturi;
- a servocontrolled pressure regulator controlling a gas pressure in the gas conduit depending on air pressure in the air conduit;
- and
- wherein the flame generator comprises a tube, a burner and a gas injector each placed within the nozzle, the tube being positioned at least partly around the burner for cutting a flow of fresh air into two.
