Abstract

Provided are a dust collection base station, a dust cup for a dust collector, a cleaning device and a dust collection method, which belong to the field of cleaning devices. The dust collection base station includes a base station body and a cover opening structure, where an end of the base station body is provided with an accommodating groove; the cover opening structure is located on a side wall of the accommodating groove; and the cover opening structure is configured to trigger unlocking of a dust discharge cover of a dust cup when an air pressure in the accommodating groove is within a preset negative pressure range. During unlocking, since the air pressure in the accommodating groove is within the preset negative pressure range, the air pressure difference between the dust cup and the accommodating groove is within an acceptable range. In addition, the impact generated when the dust discharge cover is opened under the action of the air pressure difference on both sides is also within an acceptable range. Thus, the debris in the dust cup enters the accommodating groove under the action of the air pressure difference between the dust cup and the accommodating groove. This design reduces or even avoids the residue of debris in the dust cup, and avoids impairing the normal operation of the cleaning device due to excessive impact generated when the debris enters the accommodating groove.
