[0030] The working principle of the indoor air quality zoning detection device provided by the utility model is as follows:

[0031] Step 1: When in use, divide the area to be detected into zones, and then bring the first exhaust pipe 6 and multiple groups of second exhaust pipes 8 to each zone respectively, and then pull the push-pull rod 12 to draw part of the gas in the area into the first exhaust pipe 6, and similarly draw the gas in the corresponding area into the second exhaust pipe 8, and then install the first exhaust pipe 6 into the first pipe groove 4 and open the air quality detector body 2. At this time, by pressing the pressing piece 14, the piston 13 can push the gas inside the first exhaust pipe 6 out, and the gas enters the cavity 3 and can be detected by the air quality detector body 2. In the same way, the gas drawn from each group of second exhaust pipes 8 is sent into the cavity 3 in turn, so that the air quality detector body 2 can detect the gas in each zone.

[0032] Step 2: When the first exhaust pipe 6 is exhausted, the second sealing block 22 will seal the second air port 16, and the first sealing block 17 will move to the right due to the compression of the gas, so that the external gas can enter the first exhaust pipe 6 through the first air port 15. When the gas inside the first exhaust pipe 6 is pushed out, the first sealing block 17 will seal the first air port 15, and the second sealing block 22 will move to the left due to the compression of the gas. At this time, the gas will be discharged from the second air port 16. When the piston 13 does not move, the first sealing block 17 and the second sealing block 22 will be respectively blocked by the elastic force of the first spring 18 and the second spring 23 to the first air port 15 and the second air port 16. When changing the partitioned gas, first start the exhaust pump 26 to quickly extract the gas inside the cavity 3, and then push the gas of the next partition into the cavity 3 for testing.

[0033] Compared with related technologies, the indoor air quality zoning detection device provided by the present invention has the following beneficial effects:

[0034] The area to be detected is divided into zones, and then the first exhaust pipe 6 and multiple groups of second exhaust pipes 8 are respectively brought to each zone, and then part of the gas in the area is sucked into the first exhaust pipe 6 by pulling the push-pull rod 12, and the gas in the corresponding area is also sucked into the second exhaust pipe 8. Then the first exhaust pipe 6 is installed inside the first pipe groove 4 and the air quality detector body 2 is opened. At this time, the piston 13 can be pressed by pressing the pressing piece 14 to push the gas inside the first exhaust pipe 6 out, and the gas enters the cavity 3 and can be detected by the air quality detector body 2. In the same way, the gas extracted from each group of second exhaust pipes 8 is sent into the cavity 3 in turn, so that the air quality detector body 2 can detect the gas in each zone. The device can perform zoned detection on indoor air and is very easy to use. When the first exhaust pipe 6 is exhausted, the second sealing block 22 The second air port 16 will be sealed, and the first sealing block 17 will move to the right due to gas compression, so that external gas can enter the first air extraction pipe 6 through the first air port 15. When the gas inside the first air extraction pipe 6 is pushed out, the first sealing block 17 will seal the first air port 15, and the second sealing block 22 will move to the left due to gas compression. At this time, the gas will be discharged from the second air port 16. When the piston 13 does not move, the first sealing block 17 and the second sealing block 22 will be respectively subjected to the elastic force of the first spring 18 and the second spring 23 to block the first air port 15 and the second air port 16. This structure can prevent the gas inside the first air extraction pipe 6 from dissipating easily. When changing the partitioned gas, first start the vacuum pump 26 to quickly extract the gas inside the cavity 3, and then push the gas of the next partition into the cavity 3 for testing. This structure can improve the working efficiency of the equipment.
