[0031] As a further explanation of the mounting bracket 1.2, a temperature sensing unit 1.5 is arranged on the mounting bracket 1.2, the temperature sensing unit 1.5 is arranged towards the oil inlet hole 1.1, and the temperature sensing unit 1.5 is used to detect the temperature inside the combustion cylinder 4, thereby accurately controlling the air outlet temperature.

[0032] In addition, a detection bracket 1.6 is arranged at the air inlet end of the combustion cylinder 4, an audible and light sensing unit 1.7 is arranged on the detection bracket 1.6, a detection hole 1.8 is arranged on the combustion cylinder 4 and is arranged opposite to the audible and light sensing unit 1.7, and the audible and light sensing unit 1.7 is used to detect whether the oil in the combustion cylinder is normally combusted, thereby ensuring the normal operation of the heater.

[0033] Preferably, the air guide vane 2.2 has a first arc-shaped air guide surface 2.1, and the air guide vanes 2.2 are staggered. The first arc-shaped air guide surface 2.1 on the air guide vane 2.2 guides the air, increases the air intake, and thus improves the heating effect.
