Referring to fig. 8 and 9, in some embodiments, a portion of the upper surface 46 near the dust exhaust portion 218 is arched toward the top portion 211, and a portion of the upper surface 46 near the air inlet 217 is arched toward the top portion 211. The portion of the upper surface 46 near the air inlet 217 is arched toward the top 211, that is, the portion of the upper surface 46 near the air inlet 217 is the first slope 48, so that the dust and debris entering from the air inlet 217 can enter the concave space 47 along the first slope 48, and the dust and debris can be prevented from being retained. The part of the upper surface 46 close to the dust exhaust part 218 is arranged in a mode of being arched towards the direction close to the top part 211, namely, the part of the upper surface 46 close to the dust exhaust part 218 is a second slope 49, when the vacuum negative pressure suction force is cancelled at the dust exhaust part 218, dust and debris close to the dust exhaust part can automatically fall into the concave space 47 along the second slope 49, and therefore the dust and debris can be prevented from being detained at the dust exhaust part to cause garbage leakage. The bottom surface of the dust box housing is defined as a horizontal surface, and the inclination angle of the first slope 48 with respect to the horizontal surface is larger than that of the second slope 49 with respect to the horizontal surface, thereby facilitating guiding the concave space 47 to discharge the dust discharging part 218.

Referring to fig. 10, further, the area where the air inlet side 34 is located is divided into a first area 51 and a second area 52 by the flow-guiding side plate 23, the first area 51 is located on one side of the flow-guiding side plate 23 close to the air inlet 217, the second area 52 is located on one side of the flow-guiding side plate 23 away from the air inlet 217, when the air outlet 216 is subjected to suction negative pressure, at least part of the air flow entering from the air inlet 217 enters the air exhaust channel 215 through the first area 51, and at least part of the air flow entering from the air inlet 217 bypasses the flow-guiding side plate 23 and enters the air exhaust channel 215 through the second area 52. After the airflow entering from the air inlet 217 impacts the flow guide side plate 23, the flow guide side plate 23 is used for intercepting, decelerating and laterally guiding the airflow entering from the air inlet 217, dust debris with large mass in the dust-carrying airflow impacts the flow guide side plate 23 and then is separated from the airflow and falls to the bottom 212 of the dust box shell 21, the airflow with reduced dust amount is divided into two airflows which enter the air exhaust channel 215 through the first area 51 and the second area 52 respectively, and the blocking of the filter assembly 22 caused by the fact that the dust debris highly impact the same position of the filter assembly 22 is avoided.
