Referring to fig. 1 to 2 and fig. 2 to 6, an embodiment of the present invention provides an air inlet box 100, including: a case 110 having a circulation tuyere 120 and a fresh air tuyere 130; a damper panel 200 including a wind blocking portion 210 and a vent hole 220, the damper panel 200 being rotatably installed on the case 110, the damper panel 200 having a first rotational position and a second rotational position; when the damper panel 200 is located at the first rotation position, the wind blocking part 210 closes the circulation wind opening 120, and the ventilation hole 220 and the fresh wind opening 130 at least partially overlap in the orthographic projection of the plane where the damper panel 200 is located; when the damper panel 200 is located at the second rotation position, the wind blocking part 210 closes the fresh air opening 130, and the ventilation hole 220 and the circulating air opening 120 are at least partially overlapped in the orthographic projection of the plane where the damper panel 200 is located; and a first screen 300 installed in the ventilation hole 220.

It should be noted that the fresh air inlet 130 is communicated with a fresh air pipe (not shown) extending to the outdoor side, and is used for absorbing outdoor fresh air and sending the fresh air to the fresh air fan 600; the circulation wind port 120 is connected to an indoor air inlet pipe (not shown) at the indoor side for absorbing the circulation wind at the indoor and sending the circulation wind to an air conditioner (not shown).

It should be noted that the damper panel 200 is a sheet-shaped panel, and the damper panel 200 is tightly attached to the box body 110 to ensure the sealing effect of the wind blocking portion 210 on the circulation wind gap 120 or the fresh wind gap 130. The sheet-like plate is provided with a vent hole 220, and the area of the sheet-like plate without the hole may be a wind shielding portion 210. When the damper panel 200 rotates to the first rotation position, the circulating air opening 120 is located in the wind blocking portion 210 on the orthographic projection of the plane where the damper panel 200 is located; when the damper panel 200 rotates to the second rotation position, the fresh air inlet 130 is located in the wind blocking portion 210 on the orthographic projection of the plane where the damper panel 200 is located. That is, the wind blocking part 210 may completely cover the circulation tuyere 120 or the fresh tuyere 130.

The case 110 is provided with a circulation air opening 120, a fresh air opening 130, and a damper panel 200 for switching the opening and closing of the two air openings. When the damper panel 200 is rotated to the first rotation position, at least part of the fresh air inlet 130 is opened and the circulating air inlet 120 is closed, and the air inlet box 100 provides outdoor fresh air for the fresh air fan 600; when the damper panel 200 is rotated to the second rotational position, at least a portion of the circulation port 120 is opened and the fresh air port 130 is closed, and the inlet box 100 provides indoor circulation air to the air conditioner. That is, the air inlet box 100 has a simple structure, can effectively prevent the outdoor fresh air and the indoor circulating air from being mixed, and the air inlet box 100 operates more reliably. In addition, the first filter screen 300 is installed in the ventilation hole 220 of the air door panel 200, so that outdoor fresh air or indoor circulating air entering the air inlet box 100 can be filtered, and the quality of inlet air of the air inlet box 100 is improved.
