[0030] like Figure 1-Figure 8 As shown, in this embodiment: an inner cavity 42 is opened in the shell 4, and a first connecting port 43 and a second connecting port 44 are opened on two side surfaces of the shell 4. The first connecting port 43 and the second connecting port 44 are connected with the inner cavity 42, and are respectively connected with the first connecting pipe 1 and the second connecting pipe 2; the effect achieved by the above components is: the inner cavity 42 is connected with the first connecting pipe 1 and the second connecting pipe 2 through the first connecting port 43 and the second connecting port 44 respectively.

[0033] like Figure 1-Figure 8As shown, in this embodiment: movable cavities 63 are symmetrically opened in the adjustment surface 61, and adjustment plates 64 are slidably connected in the two movable cavities 63. A plurality of through holes 65 are opened in the adjustment plate 64, and the through holes 65 have the same size as the vent 62. When the two adjustment plates 64 are farthest apart, the plurality of through holes 65 correspond to the vent 62, and when the two adjustment plates 64 are closest to each other, the plurality of through holes 65 and the vent 62 are misaligned with each other; the effects achieved by the above components are: the adjustment plate 64 can adjust the flow rate of the gas passing through the vent 62; during the sliding process of the adjustment plate 64 in the movable cavity 63, the through holes 65 and the vent 62 are switched back and forth between correspondence and misalignment, and the flow rate of the gas passing through the vent 62 is changed by changing the size of the caliber of the vent 62, so as to achieve the purpose of adjusting the flow rate of the gas entering the indoor unit of the air conditioner.

[0034] like Figure 1-Figure 8 As shown, in the present embodiment: a through hole 66 is opened between the through holes 65, when the two adjustment plates 64 are farthest apart, a number of through holes 66 are blocked by the adjustment surface 61, and when the two adjustment plates 64 are closest to each other, a number of through holes 66 enter the vent 62; the effect achieved by the above components is: when the two adjustment plates 64 are closest to each other, when the through hole 65 is misaligned with the vent 62, the through hole 66 enters the vent 62, which can achieve the purpose of ventilation and prevent poor gas flow.

[0035] like Figure 1-Figure 8 As shown, in this embodiment: a moving groove 45 is opened in the shell 4, and a driving mechanism 7 for driving the two adjustment plates 64 to move is provided in the moving groove 45.

When the external environment changes and the gas flow rate needs to be adjusted, the motor 74 is started, and the motor 74 drives the bidirectional screw 71 to rotate. The bidirectional screw 71 drives the two moving blocks 73 to move closer to or away from each other through the threaded sleeve 72. The two moving blocks 73 drive the two adjustment plates 64 to move closer to or away from each other along the moving cavity 63. The through hole 65 and the vent 62 are switched back and forth between correspondence and misalignment. By changing the size of the caliber of the vent 62, the flow rate of the gas passing through the vent 62 is changed, thereby achieving the purpose of adjusting the flow rate of the gas entering the indoor unit of the air conditioner.
