The open end of the blind mounting hole faces outward (i.e., the side away from the air duct), and the temperature detecting member 20 is typically a temperature sensor. The blind mounting holes can reduce the wall thickness of the first single body 11 and/or the second single body 12, and the temperature in the air duct can be quickly transferred to the inner wall surfaces of the blind mounting holes through heat transfer. Thus, when mounting, the temperature detection member 20 is fixed in the mounting blind hole, and the temperature detection member 20 is brought into close contact with the inner wall surface of the mounting blind hole. Therefore, the temperature on the inner wall surface of the mounting blind hole can be detected by the temperature detection piece 20 in time, and the accuracy of temperature detection is improved.

As shown in fig. 11, in the embodiment of the present invention, the bottom of the installation blind hole is protruded toward the inside of the air duct. Namely, the blind mounting holes formed in the first single body 11 and/or the second single body 12 protrude toward the inside of the air duct, so as to form a bulge structure. Set up like this, wind blows to the swell at the in-process that flows in the wind channel, and the heat of wind can be received to the swell, and the temperature that received heat made the swell structure risees to conduct to temperature detection spare 20 through the heat transfer, make temperature detection spare 20 can in time detect the temperature state, realize the detection to the temperature in the wind channel. In the embodiment of the present invention, the mounting structure 17 is disposed on the second single body 12.

Specifically, since the temperature detecting member 20 is not directly disposed in the air duct, the temperature detecting member 20 detects the temperature by means of thermal conductivity sensing. Therefore, in an actual setting, the difference between the value of the actual temperature in the air duct and the value of the temperature detected by the temperature detecting member 20 can be corrected to ensure the accuracy of the temperature detection. Meanwhile, a plurality of mounting structures 17 can be arranged at intervals, and a temperature detection piece 20 is fixed in each mounting structure 17. Therefore, the temperature in the air duct is detected by the plurality of temperature detection pieces 20, and the accuracy of temperature detection in the air duct is improved in the temperature detection mode.
