[0024] Working principle: When working, first place the device in the air outlet duct of the air conditioner, turn on the two motors 2044, so that the driving gear 2043 rotates to drive the double-headed screw 2041 to rotate, thereby driving the two first internal plates 2021 to move away from each other, and the two second internal plates 2031 to move closer to each other in the same direction; When the two first inner plates 2021 move away from each other, the two driving wheels 2024 are driven to move away from each other. When the two driving wheels 2024 are adjusted to contact the inner walls of both sides of the air outlet duct, the body 1 is adjusted to a state where the air outlet duct is laterally centered. When the two second inner plates 2031 approach each other, the I-shaped frame 20341 is driven to move toward one side of the machine body 1. Since the two guide push rods 20342 on the I-shaped frame 20341 are respectively slidably installed in the guide slide grooves 2039 on the upper and lower rotating arms 2036, and the ends of the upper and lower rotating arms 2036 away from the machine body 1 are respectively tilted upward and downward, when the I-shaped frame 20341 moves toward one side of the machine body 1, the two guide push rods 20342 push the two rotating arms 2036 away from each other, pushing the tilt angle of the rotating arms 2036 to increase, thereby raising the height of the machine body 1. In the original state, the driven wheel 2038 on the lower rotating arm 2036 contacts the inner bottom wall of the air outlet duct. As the rotating arm 2036 continues to tilt, until the driven wheel 2038 on the upper rotating arm 2036 contacts the inner top wall of the air outlet duct, the machine body 1 is in a longitudinally centered state. When the two driving wheels 2024 move away from each other, since the middle longitudinal plate 3042 is fixedly connected to the first mounting frame 2023 through the first connecting rod 3041, the two middle longitudinal plates 3042 are driven to move away from each other, and the movable transverse plate 3033 is fixedly connected to the corresponding movable longitudinal plate 3044, thereby driving the two movable transverse plates 3033 on the middle transverse plate 3031 to move away from each other and unfold, so that the ends of the two movable transverse plates 3033 that move away from each other contact the inner walls of the two sides of the air outlet duct, and at the same time, during the outward rotation of the upper and lower rotating arms 2036, due to the second mounting frame 2023, the two movable transverse plates 3033 on the middle transverse plate 3031 move away from each other and unfold, The end of the push rod 3036 on the frame 2037 is slidably mounted inside the transverse groove 3035 on the movable transverse plate 3033, thereby driving the movable transverse plate 3033 and the middle transverse plate 3031 to move longitudinally along with the second mounting frame 2037, thereby pulling the two movable longitudinal plates 3044 away from each other, until the ends of the two movable longitudinal plates 3044 away from each other contact the upper and lower inner walls of the air outlet duct, so that the two upper and lower cleaning members 303 and the two side cleaning members 304 are unfolded to adapt to the inner wall of the air outlet duct, so that the bristles 305 can contact the inner wall of the air outlet duct; During the movement of the middle horizontal plate 3031, the upper and lower dust collecting members 404 are pulled away from each other by the third connecting rod 406, and during the movement of the first mounting frame 2023, the dust collecting members 404 on both sides are driven to move away from each other, so that the four dust collecting members 404 are respectively arranged close to the four inner walls of the air outlet duct; Subsequently, the driving wheel 2024 rolls and drives the body 1 to move along the air outlet duct under the action of friction. During the movement, the bristles 305 continuously clean the inner wall of the air outlet duct to sweep away the dust attached to the air outlet duct. At the same time, the fan 412 is turned on to drive the air inside the air outlet duct to enter the circulation chamber 401 through the adsorption head 4043, the adsorption box 4042 and the piston tube 4041. When the air enters the circulation chamber 401, the swept dust is driven into the circulation chamber 401 together. Under the guidance of the fan 412, the dust and air enter the cavity of the collection box 408, and the swept dust is blocked under the filtering action of the filter plate 410, and the air returns to the inside of the air outlet duct from the connecting groove 411 and the holes in the fan 412 shell, thereby completing the collection of dust.
