When the cleaning plate moves to contact the impact block, the cleaning plate continues to move, causing the short shaft to rotate. At the same time, when the cleaning plate moves to no longer contact the impact block, the short shaft is reset under the influence of the elastic force of the third torsion spring, causing the impact block to reset. The impact block contacts the cleaning plate to produce an impact, which shakes off the impurities on the surface of the cleaning plate, preventing the cleaning plate with impurities sticking to it from contacting the concentration monitor and causing damage to the concentration monitor.
