[0016] (3) In the present invention, the connection plate is driven to rotate upward by the rotation of the rotating plate. The dust inside the collection box is fully mixed with water by the rotation of the connection plate upward, which can increase the contact area between water and dust particles, making it easier for water droplets to adsorb and wrap dust particles, thereby preventing dust from adhering to the inside of the collection box and affecting the dust removal effect when the sealing slide plate is opened to drain water. At the same time, the dust and water are fully mixed by moving the push plate away from the connection plate, so that when the sealing slide plate is pulled upward, the dust can be discharged along with the water, thereby improving the dust removal effect.
