Description

Technical Field

[0001] This utility model relates to the field of air quality detection technology, specifically to a sampling device for air quality detection. Background Technology

[0002] Air quality is receiving increasing attention these days, as it directly impacts human health. Indoor air quality has the greatest impact on health in daily life, making air quality testing essential.

[0003] According to the description in the patent application CN217638231U, "This utility model discloses an air quality sampling device, including a support plate, a piston cylinder, an air intake head, an exhaust pipe, a collection bottle, a placement plate, a sliding member, a driving assembly, and a rotating assembly. During air sampling, the collection bottle is connected to a threaded pipe installed at one end of the exhaust pipe via a threaded section. The driving assembly drives the sliding member installed in the piston cylinder to slide. When the sliding member slides to one side in the piston cylinder, a negative pressure is generated in the piston cylinder. At this time, the air intake head installed on the connecting pipe draws air into the piston cylinder. When the sliding member slides to the other side, the sliding member compresses and transports the gas in the piston cylinder to the collection bottle connected to the exhaust pipe. After collection, the rotating assembly drives the placement plate to rotate, and then another collection bottle is connected to the exhaust pipe to collect gas. This allows for the collection of multiple air samples, improving the accuracy of the detection."

[0004] Regarding the above description, the applicant believes the following issues exist:

[0005] In use, this utility model connects a threaded section on the collection bottle to a threaded pipe installed at one end of the exhaust pipe. The drive unit drives the gear to rotate, and the rotation of the gear, through meshing with the toothed plate, causes the toothed plate to slide on the horizontal plate. The sliding of the toothed plate, through the drive rod connected to it, causes the sliding element to slide back and forth in the piston cylinder. In actual use, because the device requires multiple manual operations during the placement of the collection bottle, the sampling efficiency is affected. At the same time, the device directly draws in air, which cannot meet the needs of filtering dust or other components in the air for subsequent testing due to different sampling requirements. Therefore, it is necessary to improve the sampling device for air quality testing to solve the above problems. Utility Model Content

[0034] Example 2:

[0035] Based on Embodiment 1, the existing technology involves direct air intake, which fails to meet the requirement of filtering dust or other components in the air for subsequent testing due to different sampling needs. Therefore, this utility model provides Embodiment 2 to solve the above-mentioned technical problem. Please refer to Embodiment 2. Figure 5 Furthermore, in conjunction with Embodiment 1, the auxiliary filtration mechanism 9 includes a filter plate 91. The filter plate 91 is inserted into the air intake box 6.

The operator pulls the sliding plate 95, and the movement of the sliding plate 95, in conjunction with the spring 94, moves the locking block 96. The operator then inserts the appropriate filter plate 91 into the air inlet box 6 and releases the sliding plate 95. Under the action of the spring 94, the locking block 96 is inserted into the fixing block 92. The operator then inserts the sampling canister 824 into... Inside the limiting frame 823, the first motor 812 operates, causing the connecting block 813 to rotate. This, in conjunction with the limiting plate 815, causes the support frame 814 to rotate, thereby rotating the four sampling canisters 824 in batches and evenly to the bottom of the sealing gasket 7. When the sampling canister 824 moves to the bottom of the sealing gasket 7, the second motor 825 operates, causing the threaded rod 826 to rotate. This, in conjunction with the limiting rod 827, causes the movable frame 822 to move. This, in conjunction with the limiting frame 823, causes the sampling canister 824 to move until it comes into contact with the sealing gasket 7. Then, the air pump 5 operates, in conjunction with the connecting pipe, the air inlet box 6, and the one-way valve inside the sampling canister 824, to begin the sampling process.
