Specifically, the mesh plate 526 is provided with a plurality of movable small flaps 5261. The air supply mechanism 50 is connected to the air intake device and the air exhaust device 43 of the air conditioning mechanism 40, and assists the air conditioning mechanism 40 in supplying air to the room and exhausting air from the room by natural outdoor air. The air inlet box 51 is divided into three directions, namely a first air inlet direction port 511, a second air inlet direction port 512 and a third air inlet direction port 513 symmetrical to the second air inlet direction port 512, when air enters from the first air inlet direction port 511, the first turning plate 515 and the second turning plate 516 block the second air inlet direction port 512 and the third air inlet direction port 513 respectively through rotation, and air flow flows in from the first air inlet direction port 511 and is discharged from the air outlet direction port 514. When the wind direction is the second wind inlet direction port 512, the first flap 515 rotates to block the first wind inlet direction port 511, and the second flap 516 rotates to block the third wind inlet direction port 513, so that the wind flows in from the second wind inlet direction port 512 and is discharged from the wind outlet direction port 514. The third air inlet direction port 513 is opposite to the second air inlet direction port 512, and the principle of the third air inlet direction port is the same as that of the second air inlet direction port 512, which is not described herein again. The air discharge principle of the air discharge box 52 is mainly the bernoulli principle, and natural air passes through the air duct and then can suck out indoor air. The specific working principle is as follows:

the exhaust box 52 can have three directional air inlets, which are respectively a first exhaust directional port 521, a second exhaust directional port 522 and a third exhaust directional port 523, and the inner diameters of the first exhaust directional port 521 and the second exhaust directional port 522 gradually decrease from large to small; the inner diameter of the third exhaust directional port 523 gradually increases from small to large, the airflow inlet 524 is arranged on the section with the smallest inner diameter, when the first exhaust directional port 521 supplies air, the third turning plate 525 blocks the second exhaust directional port 522 through rotation, and the air is exhausted from the third exhaust directional port 523. When air enters the second air exhaust direction port 522, the third turning plate 525 blocks the first air exhaust direction port 521 through rotation, and the air is exhausted from the third air exhaust direction port 523. The third exhaust direction port 523 is opposite to the second exhaust direction port 522, and the air flow direction principle is the same as the second exhaust direction port 522, which is not described herein again.

The mesh plate 526 is provided with a plurality of movable small flaps 5261. When outdoor air passes through the air exhaust box 52, the airflow on the upper side of the mesh plate 526 has high flow speed and low pressure, the airflow on the lower side of the mesh plate 526 flows upwards, and the airflow inlet 524 on the lower side is communicated with the indoor space, so that the effect of exhausting indoor air is achieved. The indoor venue air conditioning device provided by the embodiment has the advantages of simple structure of the air supply mechanism and good air exhaust effect.
