[0045] The first guide structure 63 includes an air outlet housing 631 that fits with the outer wall of the louver blade 621. The outer wall of the air outlet housing 631 is used to guide the airflow entering between two adjacent louver blades 621. The inner wall of the air outlet housing 631 is provided with a plurality of air outlet slots 634 evenly distributed in an annular shape. The air outlet slots 634 serve as outlets to guide the airflow entering the monitoring slot 623 to the outside. A fixing strip 633 is separated between each two adjacent air outlet slots 634. The fixing strip 633 is used to fit and fix with the outer wall of the louver blade 621, so that the entire air outlet housing 631 is fixed to the louver blade 621. The outer wall of the air outlet shell 631 is provided with a second fixing hole 632 corresponding to the first fixing hole 622. The air outlet shell 631 is fixedly connected by an annular convex section 6311 and an annular concave section 6312.

[0046] like Figure 3 and Figures 7 to 9As shown, the second guide structure 66 includes a first air filter plate 664 fixedly connected to the inner surface wall of the guide hole 626, and the second guide structure 66 is fixed to the inner surface wall of the clamping groove 662 through the first air filter plate 664, so that the sensor placement block 661 of the second guide structure 66 is located inside the monitoring groove 623, and the guide block 665 of the second guide structure 66 is located in the gap between the two louvers 621. The top of the first air filter plate 664 is fixedly connected with the sensor placement block 661, and the sensor placement block 661 is an inverted cone structure, and the outer wall of the sensor placement block 661 is an outward convex structure. A clamping groove 662 is provided on the top of the block 661, and a sensor clamping structure 68 is connected to the inside of the clamping groove 662. The sensor clamping structure 68 is used to install a cylindrical sensor for monitoring. The external airflow enters the monitoring groove 623 through the first filter hole 663 on the first air filter plate 664. The airflow entering the clamping groove 662 flows to the guide ring 624 under the guidance of the convex outer wall of the sensor placement block 661, and then flows to the top of the sensor placement block 661 under the guidance of the guide ring 624 to form turbulence, which is convenient for the cylindrical sensor installed on the sensor clamping structure 68 to detect; the first air filter plate The bottom of the air filter plate 664 is fixedly connected with a guide block 665, which is formed by the first guide section 6651, the second guide section 6652 and the third guide section 6653 being fixedly connected in sequence. The first guide section 6651 and the second guide section 6652 are both convex arc-shaped ring structures, and the third guide section 6653 is a concave arc-shaped ring structure. The top of the third guide section 6653 is fixedly connected to the bottom of the first air filter plate 664; the shape of the first air filter plate 664 is adapted to the shape of the guide hole 626, and the bottom of the guide block 665 is a convex structure. The guide block 665 is used to interact with the shutter blade 621 above In order to guide the external airflow, the outer wall of the guide block 665 is fixedly connected with a plurality of evenly distributed annular partitions 666, the top of the partition 666 is in contact with the bottom of the first air filter plate 664, and the first air filter plate 664 is provided with a plurality of evenly distributed first filter holes 663 between two adjacent partitions 666. The plurality of partitions 666 are used to divert the incoming airflow, thereby increasing the passing speed of the airflow through the first filter holes 663. A threading hole 667 connected to the clamping groove 662 is provided at the center of the guide block 665, and the threading hole 667 is used for passing the cylindrical sensor line.

[0047] like Figures 8 to 10As shown, the sensor clamping structure 68 includes a plurality of groups of clamping sheets 681 fixedly connected to the bottom of the clamping groove 662, and the plurality of groups of clamping sheets 681 are annular parts. The cylindrical sensor inserted therein is clamped and fixed by the clamping force of the plurality of groups of clamping sheets 681. The top of the clamping sheet 681 is biased toward the center position of the clamping groove 662. The biased clamping sheet 681 can provide sufficient clamping force for the cylindrical sensor. One side surface of the clamping sheet 681 is a concave structure. The clamping sheet 681 with the concave structure can be adapted to clamp the outer wall of the cylindrical sensor. The clamping sheet 681 is formed by the first clamping section 6811, the second clamping section 6812 and the third clamping section 6813 fixedly connected in sequence. The widths of the first clamping section 6811, the second clamping section 6812 and the third clamping section 6813 increase in sequence, so that when the third clamping section 6813 is squeezed by the cylindrical sensor, the third clamping section 6813 provides more deformation force. The bottom end of the third clamping section 6813 is fixedly connected to the bottom edge of the clamping groove 662, and the first extrusion sheet 682 is fixedly connected to one side of the third clamping section 6813. The end of the first extrusion sheet 682 away from the third clamping section 6813 is fixedly connected to the inner surface wall of the clamping groove 662. The third extrusion sheet 684 and the second extrusion sheet 683 are fixedly connected to one side of the first clamping section 6811. The ends of the second extrusion sheet 683 and the third extrusion sheet 684 away from the first clamping section 6811 are fixedly connected to the inner surface wall of the clamping groove 662, wherein the thickness of the first extrusion sheet 682, the second extrusion sheet 683 and the third extrusion sheet 684 gradually change from thin to thick from the middle to the two ends, and the first extrusion sheet 682, the second extrusion sheet 683 and the third extrusion sheet 684 provide extrusion force for the clamping sheet 681 with the assistance of deformation force, and the clamping sheet 681, the first extrusion sheet 682, the second extrusion sheet 683 and the third extrusion sheet 684 are an integrally formed structure.

[0048] When the cylindrical sensor needs to be fixed, the connecting wire of the cylindrical sensor is first passed through several groups of clamping pieces 681, and then passed through the threading hole 667. When the cylindrical sensor is inserted into the sensor clamping structure 68, its bottom squeezes the first clamping section 6811, the second clamping section 6812 and the third clamping section 6813 in sequence during insertion. As the cylindrical sensor squeezes the first clamping section 6811, the second clamping section 6812 and the third clamping section 6813, the third squeezing piece 684, the second squeezing piece 683 and the first squeezing piece 682 are compressed and deformed. At the same time, the deformed third squeezing piece 684, the second squeezing piece 683 and the first squeezing piece 682 assist the clamping piece 681 in squeezing the outer wall of the cylindrical sensor under the force of restoring the deformation. After the entire cylindrical sensor is inserted, the bottom of the cylindrical sensor is inserted into the threading hole 667 to limit the bottom, and the outer wall of the cylindrical sensor is squeezed and fixed by the clamping piece 681.

[0049] like Figure 3 , Fig.11 and Fig.12 As shown, the dust cover 67 is provided with a plurality of evenly distributed second filter holes 671, which facilitate airflow to pass through while preventing external dust from entering the monitoring slot 623. The aperture of the second filter hole 671 is greater than 10 microns. A circular ring 672 is fixedly connected to the edge of the dust cover 67, and two symmetrically distributed reciprocating plates 673 are fixedly connected to the outer wall of the circular ring 672. The reciprocating plates 673 are elastic structures, and one end of the reciprocating plates 673 is fixedly connected to the connection position between the circular ring 672 and the dust cover 67, and the other end is fitted with the outer wall of the circular ring 672. The thickness of the circular ring 672 gradually changes from thin to thick from the middle to the two ends, and the outer wall of the reciprocating plates 673 is fitted with the inner wall of the annular groove 625.

[0050] During installation, the circular ring 672 with two reciprocating pieces 673 is inserted into the annular groove 625. When inserted, when the reciprocating pieces 673 are in the notches of the annular groove 625, the reciprocating pieces 673 are squeezed by the notches to fit against the outer wall of the circular ring 672, so that the circular ring 672 can enter the annular groove 625.

[0051] The working principle of the technical solution provided by the present invention is as follows: when it is necessary to measure the temperature, humidity, carbon dioxide and particulate matter in the ambient air, first install the corresponding cylindrical sensors used to detect these. When installing the temperature and humidity sensors, carbon dioxide sensors and PM2.5 / PM10 sensors, first pass the connecting wires of the cylindrical sensors through the groups of clamping pieces 681 and then pass them out through the threading holes 667. When the corresponding cylindrical sensors are inserted into the sensor clamping structure 68, their bottoms squeeze the first clamping section 6811, the second clamping section 6812 and the third clamping section 68 in sequence. 13. As the cylindrical sensor is squeezed by the first clamping section 6811, the second clamping section 6812 and the third clamping section 6813, the third squeezing sheet 684, the second squeezing sheet 683 and the first squeezing sheet 682 are compressed and deformed. At the same time, the deformed third squeezing sheet 684, the second squeezing sheet 683 and the first squeezing sheet 682 assist the clamping sheet 681 in squeezing the outer wall of the cylindrical sensor under the force of restoring the deformation. After the entire cylindrical sensor is inserted, the bottom of the cylindrical sensor is inserted into the threading hole 667 to limit the bottom, and the outer wall of the cylindrical sensor is squeezed and fixed by the clamping sheet 681.

[0052] The first air filter plate 664 on the second guide structure 66 is passed through the air outlet shell 631 and fixedly installed on the inner surface wall of the clamping groove 662 on the louver structure 62. Then the passed air outlet shell 631 is installed on the surface wall of the louver 621 below. The installation is carried out in this way in sequence until all the second guide structures 66 and air outlet shells 631 are fixedly connected to the louver 621. Then all the louvers 621 are fixed together through three connecting columns 64. Finally, the top plate 61 carrying the light sensor 611 is placed on the top of the connecting column 64.

[0053] When detecting the ambient air quality, the airflow in the air will enter the gap between the two louvers 621, and the airflow will follow the surface of the guide block 665, and then be diverted by the partition 666 to pass through the first filter hole 663 and enter the monitoring slot 623. The airflow entering the clamping slot 662 will flow toward the guide ring 624 under the guidance of the convex outer wall of the sensor placement block 661, and then flow toward the top of the sensor placement block 661 under the guidance of the guide ring 624 to form turbulence, which is convenient for the cylindrical sensor installed on the sensor clamping structure 68 to perform detection, thereby obtaining various data on the ambient air quality.

[0054] When the airflow entering the monitoring slot 623 is large, the dust cover 67 will be blown. When the dust cover 67 is blown, the ring 672 on the dust cover 67 will be offset. The offset ring 672 will squeeze the reciprocating piece 673, thereby squeezing the reciprocating piece 673 to deform. When the airflow stops, the reciprocating piece 673 recovers its deformation, driving the ring 672 to return to its initial position. The deformation of the reciprocating piece 673 drives the dust cover 67 to reciprocate, causing the dust cover 67 to vibrate, thereby shaking off the dust stuck on the dust cover 67 to avoid blockage, which causes the internal cylindrical sensor to detect inaccurate data.
