In some seasons with mild climate, when the air conditioner is not used, the deodorant in the inner wall of the fixed cylinder 601 can be volatilized from the air hole 605, and the peculiar smell in the inside of the main pipeline and the auxiliary pipeline can be absorbed. When used, the peculiar smell in the gas can also be treated, so that the personnel in the room is more comfortable. With the volatilization of the deodorant, the spring three 610 is opened to push the pressing plate 608 to rise. The warning column 609 on the pressing plate 608 can be inserted into the warning hole 607 on the sealing cover 603. The position of the warning column 609 can be directly observed from the maintenance opening 205 to add the deodorant in time.

[0038] Finally, when the central air conditioner is not used for a long time, the connecting plate 304 is in a reset state under the tension of the spring 306, the gears 303 on the two rotating shafts 310 do not rotate, and the two baffles 302 on the rotating shaft 310 are sealed to the shell 301, which can prevent dust from entering the inside of the secondary pipeline 203 and adhering to the fan blades 402 to reduce the rotating speed and affect air supply. When the central air conditioner needs to be used for a long time in hot or cold seasons, the connecting plate 304 is pushed to realize the contraction of the two springs 306, and the two toothed plates 307 move forward to drive the two gears 303 to rotate, and then the baffles 302 are opened, the shell 301 can exhaust air, and when the limiting block 308 on the side of the connecting plate 304 moves to the limiting groove 309 at the top of the shell 301, the limiting block 308 is turned by ninety degrees, at this time the limiting block 308 is turned to the inside of the limiting groove 309, realizing the fixation of the connecting plate 304, which is beneficial to the long-term opening of the baffles 302 for ventilation, and can also protect some air conditioner air deflectors.
