Description

Technical Field

[0028] When formaldehyde concentration testing is required, the drive motor 410 starts, and the threaded rod 409 drives the transmission plate 406 to move through the threaded block 408. When the transmission plate 406 moves, it drives the second connecting ear 407, which is wrapped with a transmission rope, to move. The transmission rope then drives the opening and closing plate 401, which is connected to the first connecting ear 405, to open.

After the test is completed, the drive motor 410 reverses to reset the transmission plate 406. At the same time, the top column 413 pushes the opening and closing plate 401 to reset, causing the magnetic groove 402 of the opening and closing plate 401 to engage with the magnetic block 403, thus closing the air guide pipe 201.
