[0039] As a technical optimization solution of the present invention, by providing a transmission motor 12 and a bevel gear 13, the sleeve 6 can be driven to rotate stably, thereby preventing the sleeve 6 from slipping.

[0040] refer to Figure 5 The bottom of the vertical plate 7 is fixedly connected to a support frame 14 sleeved on the surface of the sleeve 6 , and the top and bottom of the surface of the sleeve 6 are fixedly connected to limit rings 15 located on both sides of the support frame 14 .

[0041] As a technical optimization solution of the present invention, by providing a support frame 14 and a limiting ring 15, the sleeve 6 can be limited, and the contact area between the sleeve 6 and the bracket 9 can be increased.

[0042] refer to Figure 6 A limiting groove 16 is provided on the surface of the screw rod 8 , and a threaded component 17 is fixedly connected to the interior of the pipe 4 . The threaded component 17 is located inside the limiting groove 16 , and the threaded component 17 is threadedly connected to the limiting groove 16 .

[0043] As a technical optimization solution of the present invention, by providing a limiting groove 16 and a threaded assembly 17, the screw rod 8 can be limited to prevent the screw rod 8 from rotating with the sleeve 6.

The output end of the fan 5 is connected to a bellows 19, and the end of the bellows 19 away from the fan 5 is connected to the left side of the processing box 18.

[0045] As a technical optimization solution of the present invention, by providing a processing box 18 and a bellows 19, the airflow discharged from the fan 5 can be processed to prevent the airflow from entering the environment and causing secondary pollution to the environment.

[0046] refer to Figure 3 The filtering structure includes a mesh box 20 arranged inside the processing box 18, the interior of the mesh box 20 is filled with activated carbon particles 21, a filter coil 22 is arranged on the right side of the activated carbon particles 21, and a nano coil 23 is arranged on the right side of the filter coil 22.

[0050] The working principle and use process of the present invention are as follows: when in use, the external airflow is extracted through the pipe 4 through the fan 5, so that the external airflow passes through the pipe 4 and enters the interior of the treatment box 18. During the airflow circulation process, the transmitting end 2 can emit light to the pipe 4, and the light penetrates the pipe 4 and contacts the receiving end 3. Part of the light is blocked by the particles inside the pipe 4, so the receiving end 3 can judge the number of particles by the blocked part of the light. When it is necessary to wipe the surface of the pipe 4, turn on the transmission motor 12, and the transmission motor 12 drives the sleeve 6 to rotate through the bevel gear 13. The sleeve 6 uses the thread to push the screw 8 to rise, and the screw 8 drives the carrying ring 10 to rise synchronously through the bracket 9. The carrying ring 10 uses the wiping pad 11 to wipe the inner surface of the pipe 4 during the movement, so that the attached dust is out of contact with the pipe 4, and the dust entering the interior of the treatment box 18 can contact with the activated carbon particles 21, the filter coil 22 and the nano coil 23 in turn, so that the impurities in the airflow are separated from the gas, and the airflow discharged into the environment again is prevented from polluting the indoor environment.

[0051] To sum up: the air quality detector, by setting the sleeve 6 and the screw 8, can push the wiping structure to rise and fall, increase the moving distance of the wiping structure, avoid the wiping structure affecting the operation of the transmitting end 2 and the receiving end 3, and enable the detector 1 to have the effect of cleaning attached dust.
