Referring to fig. 5 and 7, further, the bottom 212 has two edge regions 41 disposed opposite to each other and a middle region 42 located between the two edge regions 41, the air inlet 217 of the side shell 213 is disposed corresponding to the middle region 42, and the first side plate 231 and the second side plate 232 are respectively used for shunting the airflow entering from the air inlet 217 to the two edge regions 41 to drive the garbage in the two edge regions 41 to flow to the middle region 42, and then to be discharged from the dust discharging part 218 under the vacuum suction force at the dust discharging part 218.
Referring to fig. 5 and 7, in some embodiments, the side casing 213 has a first side wall 43 and a second side wall 44 disposed opposite to the first side wall 43, and two opposite guide side walls 45, the air inlet 217 is disposed on the first side wall 43, the dust exhaust part 218 is disposed on the second side wall 44, the two guide side walls 45 are respectively connected between the first side wall 43 and the second side wall 44, the two guide side walls 45 are configured to guide the airflow to the dust exhaust part 218, and the first side plate 231 and the second side plate 232 are respectively connected to the two guide side walls 45. In the present embodiment, the two guiding sidewalls 45 are recessed toward the left and right sides of the dirt tray assembly 20 to form the two edge regions 41, respectively, such that the dirt tray housing 21 has a larger volume to contain dirt and debris.
The two guiding sidewalls 45 are substantially concave curved surfaces, and the distance between the two guiding sidewalls 45 is narrowed in a direction approaching the dust exhaust portion 218. The two guiding sidewalls 45 are respectively located at two opposite sides of the dust exhaust portion 218, and can guide the airflows guided out by the first side plate 231 and the second side plate 232 to the dust exhaust portion 218 in a concentrated manner, so as to drive the garbage of the two edge areas 41 to be guided to the dust exhaust portion 218 in a concentrated manner, thereby improving the dust exhaust efficiency.
Referring to fig. 8 and 9, further, the bottom portion 212 has an upper surface 46 on a side thereof close to the top portion 211, the upper surface 46 is connected between the dust exhaust portion 218 and the air inlet 217, the upper surface 46 is recessed away from the top portion 211 to form a recessed space 47, and the recessed space 47 forms a portion of the inner cavity 214. Wherein the recessed space 47 is adapted to facilitate collection of dust debris.
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.

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.
