[0098] Among them, the male connector of the connecting connector 8 is fixedly installed on the air intake pipe, and the air detector 1 and the spring hose 28 are connected via the connecting connector 8.

[0099] Furthermore, the sliding frame 9 is slidably mounted on the outer surface of the positioning frame 16;

[0100] The slide groove 24 is provided on the outer surface of the positioning frame 16;

[0101] The slider 25 is fixedly connected to the inner wall of the sliding frame 9, and the slider 25 is slidably connected to the sliding groove 24;

[0102] Wherein, the bolt 18 is threadedly sleeved on the sliding frame 9;

[0103] Wherein, the positioning hole 23 is provided on the outer surface of the positioning frame 16;

[0104] The end of the bolt 18 close to the positioning frame 16 slides and extends into the positioning hole 23;

[0105] The connection groove 29 is provided on the outer surface of the sliding frame 9, and the connection groove 29 is communicated with the interior of the sliding frame 9;

[0106] The connection groove 29 extends from the upper and lower surfaces of the sliding frame 9;

[0107] The connecting groove 29 is matched with the second sliding block 10 .

[0108] Furthermore, in the initial state, the connecting tubes 17 are in a vertical state, and the upper surface height of the sliding frame 9 is higher than the upper surface height of the positioning frame 16. When in use, the threaded rod 5 is screwed out of the positioning hole 23, and the sliding frame 9 can slide downward. When the sliding frame 9 is slid downward until the lower surface of the slider 25 contacts the bottom wall of the slide groove 24, the connecting tube 17 can be rotated at this time, so that the connecting tube 17 rotates around the rotating shaft 20, so that the connecting tube 17 rotates outward. When the connecting tube 17 rotates ninety degrees, the first limiting plate 21 contacts the second limiting plate 22, and then the second limiting plate 22 limits and supports the first limiting plate 21, so that the connecting tube 17 can no longer continue to rotate, and then the connecting tube 17 is in a horizontal state at this time. At this time, the air detector 1 is started, and the indoor air enters the air detector 1 through the connecting tube 17 and the collection cover, and the air quality is detected by the air detector 1;

[0109] As mentioned above, when the connecting tube 17 needs to be stored, the sliding frame 9 is slid upward, the upper surface of the sliding frame 9 contacts the lower surface of the connecting tube 17 and gives the connecting tube 17 a thrust, and the thrust connecting tube 17 rotates around the rotating shaft 20. When the sliding frame 9 moves upward to the initial state, the connecting tube 17 is in a vertical state. At this time, the bolt 18 is rotated so that the bolt 18 enters the positioning hole 23, thereby fixing the sliding frame 9. At the same time, the connecting tube 17 can be limited so that the connecting tube 17 can no longer rotate outward. By making the connecting tube 17 in a vertical state, the space occupied by the connecting tube 17 when not in use can be reduced, thereby making the air detector 1 easy to transport and carry, thereby increasing the practicality of the detection device.

[0110] As mentioned above, when it is necessary to clean the connecting pipe 17 and the spring hose 28, the fixing plate 15 is pulled out so that the fixing plate 15 drives the fixing rod 13 to move out of the fixing hole 12. In this process, the spring 14 is stretched and deformed. At this time, the second sliding block 10 can be pulled out from the first sliding block 6, and then the positioning frame 16, the sliding frame 9, the connecting pipe 17, the collecting cover, the first hose 26, the fixing box 27 and the spring hose 28 can be disassembled. At this time, the female joint and the male joint of the connecting joint 8 are rotated and separated, and then the positioning frame 16, The sliding frame 9, connecting tube 17, collecting cover, first hose 26, fixed box 27 and spring hose 28 are separated from the air detector 1, and the disassembly is convenient and efficient, saving manpower. Then, the spring hose 28, connecting tube 17, first hose 26 and fixed box 27 can be internally flushed by flushing cleaning liquid into the spring hose 28 to avoid dust accumulation in the spring hose 28, connecting tube 17, first hose 26 and fixed box 27 that affects the accuracy of indoor air quality detection, thereby ensuring the detection accuracy of the detection device and increasing the practicality of the indoor air quality detection device.

[0111] Furthermore, in this solution, the connecting groove 29 can prevent the sliding frame 9 from being restricted by the second sliding block 6 when moving downward.

[0112] Furthermore, the connecting joint 8 is a commonly used quick connector for air pipes, which is a prior art and will not be described in detail here.

[0113] Working principle: When the device is used, when it is necessary to clean the connecting tube 17 and the spring hose 28, the fixing plate 15 is pulled out, so that the fixing plate 15 drives the fixing rod 13 to move out of the fixing hole 12. In this process, the spring 14 is stretched, so that the spring 14 is stretched and deformed. At this time, the second sliding block 10 can be pulled out from the first sliding block 6, and then the positioning frame 16, the sliding frame 9, the connecting tube 17, the collecting cover, the first hose 26, the fixing box 27 and the spring hose 28 are disassembled. At this time, the female joint and the male joint of the connecting joint 8 are rotated and separated. , and then the positioning frame 16, sliding frame 9, connecting tube 17, collecting cover, first hose 26, fixed box 27 and spring hose 28 are separated from the air detector 1, and then the spring hose 28, connecting tube 17, first hose 26 and fixed box 27 can be internally flushed by flushing cleaning liquid into the spring hose 28 to avoid dust accumulation in the spring hose 28, connecting tube 17, first hose 26 and fixed box 27 that affects the accuracy of indoor air quality detection, thereby ensuring the detection accuracy of the detection device and increasing the practicality of the indoor air quality detection device.
