The positioning device 5 is a photoelectric switch, the photoelectric switch and the cam 1 or the elastic locking component 3 are arranged in the air duct 7 relatively, the photoelectric switch is arranged opposite to the cam 1 or the elastic locking component 3 and the air duct shell 8, namely on the air duct shell 8 at the other side, the photoelectric switch detects the shielding condition of the air duct baffle 2 to the light beam and is connected with the motor 4, when the air duct baffle 2 rotates to the position of completely closing the air duct 7, the air duct baffle 2 shields the light speed of the photoelectric switch, after the photoelectric switch detects the signal, the signal is transmitted to the motor 4, and the motor stops rotating. The positioning device 5 and the elastic locking component 3 are located on the same horizontal line, and the positioning device 5 is located at the position so as to be convenient for closing the motor 4 in time after the air duct baffle 2 is closed.
As an alternative embodiment, the cam 1 is a disc cam, which is simple to machine, and is convenient for the elastic locking component 3 to move according to a preset motion track, so that the overall structure of the air duct component is relatively simple.

As an optional implementation manner, as shown in fig. 3, the number of the air duct components is two, and the two air duct components are respectively located in the upper air duct and the lower air duct of the cabinet air conditioner, and the air duct components are matched with the air duct housing 8 to open or close the upper air duct and/or the lower air duct, so that independent upper air outlet or lower air outlet or simultaneous upper and lower air outlet of the cabinet air conditioner is realized.
As an alternative embodiment, the rotation of the air duct baffle 2 at a limited angle (about 90 °) can be realized by a crankshaft and rocker mechanism (the motor 4 drives the crank to rotate, and the rocker is equivalent to the air duct baffle 2 and rotates at a limited angle), so as to realize the opening or closing of the air duct 7 by the air duct baffle 2.
The working process of the air duct component provided by the invention is as follows: assuming that the air conditioner is in the lower air-out state, the upper duct flap is closed, as shown in fig. 2, at this position, the cam 1 reaches the maximum compression amount to the spring 31, and neglecting the self-locking moment of the motor 4 and the gravity of the upper duct flap 21 itself, at this time, the spring 31 has an elastic force F ═ k × x (k is an elastic coefficient, which can be selected according to actual needs, and x is a compression amount). At the moment, the centrifugal fan 6 starts to work, airflow pressure is generated in the air duct 7, the pressure has an upward thrust on the upper air duct baffle 21, the elastic force of the spring 31 enables the driven wheel 32 and the cam 1 to have a downward component force on a tangent plane, the component force is static friction force, the upper air duct baffle 21 cannot rotate, and the self-locking purpose is achieved. When air is required to be blown out upwards, the centrifugal fan 6 stops rotating, then the motor 4 drives the cam 1 to rotate, when the rotating torque is larger than the rotating torque given to the cam 1 by the elastic force of the spring 31, the upper air duct baffle 21 rotates upwards, as shown in fig. 3, the upper air duct baffle 21 reaches the maximum rotating position, and the motor 4 stops rotating, and as the motor 4 is a stepping motor, the rotating angle can be set for the motor 4 in advance, so that the motor stops rotating when the upper air duct baffle 21 is attached to the inner wall of the air duct shell 8. When the upper air outlet is closed again, the motor 4 rotates again, the rotation of the spring 31 is overcome at the moment, the motor stops rotating when the positioning device 5 rotates, the positioning device 5 is a photoelectric switch, the motor 4 can stop rotating when the position is reached, and the motor 4 is a stepping motor, so that the rotation angle of the motor 4 can be set in advance, and the upper air outlet is ensured to be closed tightly by the upper air duct baffle 21. When the motor 4 is operated in a reversing way each time, the centrifugal fan 6 stops rotating, only the motor 4 works, stable work of the air duct part is guaranteed, and noise generated when the air duct baffle 2 is closed and opened is reduced.
