         7 . The air duct structure according to  claim 6 , wherein:
 an end of the first housing is nested to an end of the second housing at a nesting position; and   at the nesting between the first housing and the second housing, the first housing is provided with a connector and the second housing is provided with a mating connector connected to the connector.   
     
     
         8 . The air duct structure according  claim 1 , wherein a connection between the mixing channel section and the air outlet channel section is at least partially in an arc transition. 
     
     
         9 . An exhaust system, comprising:
 the air duct structure according to  claim 1 ; and   the adjustment device mounted in the mixing channel section to adjust the flow rate of steam entering the exhaust channel through the steam inlet and/or the flow rate of air entering the exhaust channel through the air inlet, to control the ratio of the steam entering the exhaust channel to the air entering the exhaust channel.   
     
     
         10 . The exhaust system according to  claim 9 , wherein the adjustment device comprises an adjustment member and a drive component configured to drive the adjustment member to move between the steam inlet and the air inlet. 
     
     
         11 . The exhaust system according to  claim 10 , wherein the adjustment member has a mounting end and a free end opposite to the mounting end, the mounting end being rotatably connected between the steam inlet and the air inlet, and the free end facing towards and being located close to a communication between the mixing channel section and the air outlet channel section. 
     
     
         12 . The exhaust system according to  claim 9 , wherein the housing comprises a first cavity casing having the steam inlet and a second cavity casing having the air inlet, the first cavity casing being connected to the second cavity casing in a bending manner to define the mixing channel section between the first cavity casing and the second cavity casing. 
     
     
         13 . The exhaust system according to  claim 12 , wherein an angle is formed between a side of the first cavity casing facing towards the mixing channel section and a side of the second cavity casing facing towards the mixing channel section, the angle being smaller than 180°.
