In some embodiments, the driving device 134 is used to controllably drive one of the first and second opening/ closing devices 131 and 132 to open the air intake duct and close the other air intake duct. That is, in some embodiments, the intake air adjusting mechanism 130 may switch on the second intake duct 120 while blocking the first intake duct 110 by operating the first and second opening/ closing devices 131 and 132, so as to allow only the airflow entering the second intake duct 120 through the second intake opening 121 to flow to the indoor unit of the air conditioner.

Therefore, the driving operation can be conveniently applied to the first opening and closing device 131 and the second opening and closing device 132 on the basis of not occupying the internal space of the first air inlet pipeline 110 or the second air inlet pipeline 120, the assembly of the driving device 134 is facilitated, the structure of the air inlet device 130 is further simplified, and the assembly difficulty is reduced.
In some embodiments, the link 133 is provided with a rack 1331 extending along a length thereof. The driving device 134 includes a motor 1341 fixedly disposed in the installation space 140, and a gear 1342 coaxially connected to an output shaft of the motor 1341, the gear 1342 being engaged with the rack 1331. When the motor 1341 operates, the output shaft thereof drives the gear 1342 to rotate synchronously, the gear 1342 drives the rack 1331 to translate along the length direction of the connecting rod 133, and the connecting rod 133 moves along the length direction thereof.
Specifically, the first air intake duct 110 and the second air intake duct 120 are entirely parallel to each other, and the link 133 is vertically disposed between the first air intake duct 110 and the second air intake duct 120, so that the length direction of the link 133 is perpendicular to the extending direction of the first air intake duct 110 and the second air intake duct 120.

Accordingly, when the connecting rod 133 moves horizontally in a direction approaching the second air intake duct 120, the first opening/closing device 131 is driven to close to block the first air intake duct 110, and the second opening/closing device 132 is driven to open to conduct the second air intake duct 120.
In some embodiments, a slide 141 extending parallel to the length direction of the link 133 is provided in the installation space 140. A slider 1332 is fixed on the connecting rod 133, the slider 1332 is slidably arranged in the slide rail 141, so that the connecting rod 133 is guided by the slider 1332 to slide along the slide rail 141, the translational stability of the connecting rod 133 is ensured, the smoothness of the opening and closing actions of the first opening and closing device 131 and the second opening and closing device 132 is ensured, the vibration of the first opening and closing device 131 and the second opening and closing device 132 during the opening and closing actions is weakened, and the noise is reduced.

The first connection plate 1311 is fixedly connected to one end of the link 133; each first swing page 1312 is provided to be pivotably connected to the first connection plate 1311 about its own rotation shaft. When the first connection plate 1311 is driven by the connection rod 133 to move away from the second air intake duct 120, referring to fig. 1, the first flaps 1312 may pivot to an open state parallel to each other and spaced apart from each other, so as to allow air to flow through a gap between two adjacent first flaps 1312, and thus the first air intake duct 110 is turned on. When the first connecting plate 1311 is moved toward the direction close to the second air intake duct 120 by the driving of the connecting rod 133, referring to fig. 2, the plurality of first flaps 1312 are pivoted to an end-to-end or end-to-end overlapping state, so that a gap is prevented from being generated between two adjacent first flaps 1312, and the first air intake duct 110 is blocked. Preferably, in the open state, each of the first flaps 1312 is parallel to a flow direction of the airflow in the first air intake duct 110 (i.e., an extending direction of the first air intake duct 110) to reduce resistance of the first flaps 1312 to the airflow as much as possible.
The second opening and closing device 132 may include a second connection plate 1321 and a plurality of second flaps 1322. The second connecting plate 1321 is fixedly connected with the other end of the connecting rod 133; each second pendulum leaf 1322 is provided to be pivotably connected to the second connecting plate 1321 about its own rotation axis. That is, the specific structure of the second opening and closing means 132 is similar to that of the first opening and closing means 131, and the opening and closing processes thereof are also similar. Referring to fig. 1, when the first connecting plate 1311 is driven by the connecting rod 133 to move in a direction away from the second air intake duct 120, the connecting rod 133 drives the second connecting plate 1321 to move in a direction close to the first air intake duct 120, and the second flaps 1322 may be pivoted to an end-to-end or end-to-end overlapping state, so that a gap is prevented from being generated between two adjacent second flaps 1322, and the second air intake duct 110 is blocked. Therefore, the first connecting plate 1311 and the second connecting plate 1321 can be simultaneously moved by the movement of the connecting rod 133, so that the first air inlet pipe 110 is connected through the first flap 1312 and the second air inlet pipe 120 is simultaneously disconnected through the second flap 1322. Similarly, referring to fig. 2, when the first connection plate 1311 is moved toward the direction close to the second air intake pipe 120 by the connection rod 133, the first air intake pipe 110 may be blocked by the first flap 1312 while the second air intake pipe 120 is opened by the second flap 1322.
In some embodiments, the sum of the widths of the first flaps 1312 is greater than or equal to the width of the first air intake duct 110, and when the first opening/closing device 131 is in the closed state, the first flaps 1312 are sequentially arranged end to end or sequentially overlapped end to end along the width direction of the first air intake duct 110 so as to block the first air intake duct 110 through the first flaps 1312. The sum of the widths of the second flaps 1322 is greater than or equal to the width of the second air intake duct 120, and when the second opening/closing device 132 is in the closed state, the second flaps 1322 are sequentially arranged end to end or sequentially overlapped end to end along the width direction of the second air intake duct 120, so that the second air intake duct 120 is blocked by the second flaps 1322. That is, when the first opening/closing device 131 is in the closed state, there is no gap between two adjacent first flaps 1312 and between the first flaps 1312 and the inner wall of the first air intake duct 110. When the second opening/closing device 132 is in the closed state, there is no gap between two adjacent second flaps 1322 and between the second flaps 1322 and the inner wall of the second air intake duct 120.
In some embodiments, the first air inlet 111 of the first air inlet duct 110 is open to an indoor space where the air intake device 10 is located, and the second air inlet 121 of the second air inlet duct 120 is used for connecting a fresh air duct extending to an outdoor environment, so as to introduce outdoor inlet air through the second air inlet 121. That is, the first inlet 111 may be used as an indoor inlet to introduce indoor air into the indoor unit of the air conditioner, and the second inlet 121 may be used as an outdoor inlet to introduce outdoor fresh air into the indoor unit of the air conditioner. The intake air adjusting device 130 can select whether to introduce indoor air or outdoor fresh air into the indoor unit of the air conditioner by adjusting the first opening/closing device 131 and the second opening/closing device 132.
In some alternative embodiments, the first air intake 111 and/or the second air intake 121 may also be connected to a module having other additional functions, or other additional functional modules may be disposed in the first air intake duct 110 or the second air intake duct 120.
