It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0024] The utility model provides a sampling device for indoor environmental quality detection, such as Figure 1-5 As shown, the sampling device for indoor environmental quality detection includes: a box body 1, an air pump 2 is fixedly installed on the top of the box body 1, a delivery pipe 3 is fixedly installed on the exhaust end of the air pump 2, one end of the delivery pipe 3 extends to the interior of the box body 1, and a one-way valve is arranged on the delivery pipe 3; a mounting pipe 4 threadedly mounted on the delivery pipe 3, a gas storage bag 5 for collecting indoor gas is fixedly installed on the mounting pipe 4, and a valve is arranged on the mounting pipe 4; a hose 6 fixedly mounted on the air inlet end of the air pump 2, one end of the hose 6 is fixedly connected to an air suction pipe 7 for collecting indoor gas; a lifting mechanism installed on the box body 1 for adjusting the sampling height; a rotating mechanism assembled on the box body 1 for adjusting the sampling angle.

[0025] It should be noted that when a conventional sampling device is performing gas sampling, since the sampling device is fixedly mounted on a bracket and placed on the ground, the height of the sampling device is fixed, and therefore the height of the air inlet is also fixed. It is impossible to sample gases at multiple heights in the room, and it is impossible to achieve multi-directional sampling by rotation, resulting in low accuracy of the test results and failure to accurately reflect the indoor environmental quality.

[0026] In the scheme, when in use, the lifting mechanism is first started according to the sampling requirements, the suction pipe 7 is adjusted to the corresponding height, and then the rotating mechanism and the air pump 2 are started. The rotating mechanism will drive the box 1 to rotate forward for one circle, and then reverse for one circle, and so on. Then, under the start of the air pump 2, the suction pipe 7 can collect the air of the indoor environment in all directions, and the collected gas will be transmitted from the hose 6 to the air pump 2, and the air pump 2 will be discharged into the air storage bag 5 through the delivery pipe 3 and the installation pipe 4. When the interior of the air storage bag 5 is filled with gas, the sampling work of the indoor environment is completed, and then the valve on the installation pipe 4 is closed, and then the installation pipe 4 is rotated to make the installation pipe 4 separate from the delivery pipe 3. In this way, the disassembly work of the air storage bag 5 is completed, which can be convenient for the staff to carry it to the laboratory for testing. Since the sampling device can adjust the sampling height of the gas, it can also realize multi-directional sampling by rotation, thereby improving the accuracy of the test results, greatly improving the sampling quality, and having a good use effect.

The box 1 will first rotate forward one circle, then reverse one circle, and so on. The rotation of the box 1 will cause the suction pipe 7 to rotate together, thereby enabling the suction pipe 7 to sample the indoor gas in multiple directions.
