In one embodiment of the present invention, please refer to Fig. 1 to Fig. 3 together. Fig. 1 is a cross-sectional view of the dust collection assembly when it is not collecting dust, and its cross-section is perpendicular to the airflow direction during dust collection. The second cross-sectional view of the dust assembly when it is not collecting dust, and its cross-section is at an acute angle to the airflow direction during dust collection. Figure 3 is the third cross-sectional view of the dust collection assembly when it is not collecting dust, and its cross-section is parallel to the airflow direction during dust collection . The dust collection assembly includes a dust collection box 2 and a dust collection baffle 1 , the dust collection baffle 1 is arranged inside the dust collection box 2 to play the role of guiding the airflow and cleaning the inner wall of the dust collection box 2 .

Please refer to Fig. 1 to Fig. 3. There is a dust collection chamber inside the dust collection box 2. During the long-term use of the dust collection box 2, dust is easy to deposit on the wall of the dust collection chamber and the corners of the dust collection chamber and other dead corners, and it is not easy to clean. , the longer it is used, the smaller the available space in the dust collection chamber will be. The dust collecting box 2 has at least two side walls, a bottom wall and a top wall, and the two side walls are oppositely arranged, and the two side walls can be respectively named as the first side wall 21 and the second side wall 22 .

When the dust collection baffle 1 is installed inside the dust collection box 2, one of the side walls of the dust collection baffle 1 and the first side wall 21 of the dust collection box 2 are spaced apart, and the other side wall of the dust collection baffle 1 There is an interval between the side wall and the second side wall 22 of the dust collection box 2 , an interval between the bottom wall of the dust collection baffle 1 and the bottom wall of the dust collection box 2 , and the passage formed by the above interval is an air flow passage.
