The dirt container body 31 has a dirt container 317, that is, the dirt container body 31 can define the dirt container 317, and along a first direction of the dirt container body 31, the dirt container 317 has a first end 311 and a second end 312 opposite to each other, and the first direction of the dirt container body 31 may be understood as a height direction (i.e., a Z direction shown in fig. 2) of the dirt container body 31, and a cross-sectional area of the dirt container 317 gradually decreases from the first end 311 to the second end 312, and as some alternative embodiments of the present application, an inner peripheral wall surface 316 of the dirt container 317 gradually approaches a center line of the dirt container 317 from the first end 311 to the second end 312.

The dirt inlet pipe 40 has a dirt inlet pipe outlet 401, the dirt inlet pipe outlet 401 is disposed in communication with the dirt storage chamber 317, specifically, the dirt inlet pipe outlet 401 is disposed in direct communication with the dirt storage chamber 317, and the axial direction of the dirt inlet pipe outlet 401 is the tangential direction of the dirt storage tank body 31.

The cleaning apparatus 100 may include a dirt suction member, which may be configured as a dirt suction motor, as some alternative embodiments of the present application, the first end 311 of the dirt storage tank body 31 may have a through hole, or the first end 311 of the dirt storage tank body 31 may be opened, the dirt suction member may be directly disposed near the first end 311 of the dirt storage tank body 31, or the dirt suction member may be disposed in communication with the first end 311 of the dirt storage tank body 31 through a pipe, and under the effect of the dirt suction member, a dirt air flow (dirt+air flow) may enter the dirt storage chamber 317 through the dirt inlet pipe outlet 401 of the dirt inlet pipe 40.

As some alternative embodiments of the present application, the dirt storage tank 30 is arranged on the cleaning device 100, the cleaning device 100 is provided with a dirt suction port, the dirt inlet pipe 40 can be arranged in communication with the dirt suction port, wherein the dirt inlet pipe 40 can be arranged in direct communication with the dirt suction port, or the dirt inlet pipe 40 can also be arranged in indirect communication with the dirt suction port, under the action of the dirt suction member, dirt can be sucked into the cleaning device 100, specifically, the dirt can enter the cleaning device 100 through the dirt suction port, and then the dirt air flow (the dirt can be mixed together with the air flow when sucked) can enter the dirt inlet pipe 40 and enter the dirt storage cavity 317 through the dirt inlet pipe outlet 401, since the axial direction of the dirt inlet pipe outlet 401 is the tangential direction of the dirt storage tank body 31, and the cross-sectional area of the dirt storage chamber 317 from the first end 311 to the second end 312 gradually decreases, so that a cyclone separation effect is generated after the dirt airflow enters the dirt storage chamber 317, that is, the dirt airflow enters the dirt storage chamber 317 to form a rotating airflow, most of the rotating airflow can flow spirally along the inner peripheral wall surface 316 of the dirt storage chamber 317 to the second end 312, and dirt such as dust and particles in the dirt airflow is thrown to the inner peripheral wall surface 316 of the dirt storage chamber 317 under the action of centrifugal force, so that the dirt such as dust and particles loses inertia force once contacting with the inner peripheral wall surface 316 of the dirt storage chamber 317 and falls down to the second end 312 of the dirt storage chamber 317 along the inner peripheral wall surface 316 of the dirt storage chamber 317.
