Referring to fig. 1-4, a cleaning system 100 is disclosed that includes a vacuum cleaner 10 and a base station 20. The cleaner 10 may be a hand cleaner 10, an upright cleaner 10, a canister cleaner 10, or a walk-behind cleaner 10. The vacuum cleaner 10 includes a dust cup assembly 1 and a fan assembly 3, the fan assembly 3 generating a suction air flow, the dust cup assembly 1 collecting dirt, and the dust cup assembly 1 being provided with an ash discharge port 131. The base station 20 is used to dock at least part of the cleaner 10, the base station 20 includes a suction motor 21 and a dirt collection chamber 22, and suction force generated by the suction motor 21 transfers dirt in the dirt cup assembly 1 through the dirt discharge opening 131 into the dirt collection chamber 22. The cleaning system 100 also includes a controller operatively coupled with the various functional systems of the apparatus for controlling the operation thereof. In one embodiment, the controller is a main control printed circuit board and may include a microcontroller unit (MCU) containing at least one Central Processing Unit (CPU). A user of the device may interact with the controller via one or more user interfaces. The controller is configured to control the cleaning system 100 to perform an evacuation procedure for the dirt cup assembly 1 that includes a first phase in which the controller is configured to control operation of the suction motor 21 only for a first predetermined period of time, a second phase in which the controller is configured to control operation of the suction motor 21 and the fan assembly 3 together for a second predetermined period of time, and a third phase in which the controller is configured to control operation of the fan assembly 3 only for a third predetermined period of time. Through this evacuation procedure, dirt in the dirt cup assembly 1 can be efficiently evacuated.

Further, the dirt cup assembly 1 further includes a cover 132, the cover 132 being disposed at the dust discharge opening 131 to open or close the dust discharge opening 131, the cover 132 having a closed state and an openable state in which the cover 132 opens the dust discharge opening 131 when the suction motor 21 is operated alone. The cover 132 is automatically opened by the suction motor 21 without an additional cover opening structure. The dirt cup assembly 1 further includes a cover 132, the cover 132 closing the dirt discharge opening 131 when the fan assembly 3 is operated alone. While still allowing the dirt cup lid 132 to be closed at the end of emptying. In one embodiment, the controller comprises a first controller 3 for controlling the suction motor 21, the first controller 3 may be provided within the base station 20 and may also be provided within the cleaner 10. The first controller 3 is configured to control the suction motor 21 to operate in the first phase for a first preset period of time and then to stop for a fourth preset period of time.

In one embodiment, or on the basis of any of the above embodiments, the controller includes a second controller 4 for controlling the fan assembly 3, and the second controller 4 is configured to control the fan assembly 3 to stop operating for a fifth preset time period and then operate for a third preset time period in the third phase.

In one embodiment, or on the basis of any of the embodiments described above, the controller comprises a first controller 3 for controlling the suction assembly and a second controller 4 for controlling the fan assembly 3, the suction assembly and the fan assembly 3 operating in a synchronized interval during the second phase. I.e. after a certain period of time of co-operation of the suction assembly and the fan assembly 3, then simultaneously stopped for a certain period of time, and then co-operated for a certain period of time. The spacing may be one or more times, and by the spaced suction, the airflow within the dirt cup assembly 1 is effectively disrupted, loosening the dirt remaining in the dirt cup assembly 1, and thus providing for effective transfer of the dirt within the dirt cup assembly 1 to and within the dirt collection chamber 22.

In a preferred embodiment, the first controller 3 is located in the base station 20 and the second controller 4 is located in the cleaner 10, separately. The evacuation procedure of one embodiment is described in detail below. When the vacuum cleaner 10 is docked to the base station 20, the cover 132 of the dirt cup assembly 1 may be in an open state or a standby state, and when the cover 132 is in the standby state, the cover 132 opens the dust discharge opening 131 after receiving the suction force of the suction motor 21. An evacuation procedure is initiated, which may be automatic operation of the device after docking to the base station 20, or may be initiated by the user via a control button. The evacuation procedure comprises three phases, wherein after the evacuation procedure is initiated, in a first phase, a first one of the controllers 3 first controls the suction motor 21 to operate for a first predetermined period of time (e.g., 3S), during which time the suction motor 21 opens the cover 132 to transfer a substantial portion of the dirt from the dirt cup assembly 1 into the dirt collection chamber 22; the first controller 3 then controls the suction motor 21 to stop for a fourth preset period of time. After the suction motor 21 stops for the fourth preset time period, a second stage is entered, in the second stage, the controller simultaneously controls the suction motor 21 and the fan assembly 3 to operate together for a preset time period (2S), then the suction motor 21 and the fan assembly 3 simultaneously stop for the preset time period (2S), and finally the suction motor 21 and the fan assembly 3 are controlled to operate together for the preset time period (2S). In this process, operation of the fan assembly 3 can disrupt the airflow generated by the suction motor 21, causing the dirt in the dirt cup assembly 1 to be disturbed and then transferred into the dirt collection chamber 22 of the base station 20, at which time the dirt in the dirt cup assembly 1 is substantially emptied. And entering a third stage, at this time, the suction motor 21 and the fan assembly 3 are both in a stop state, the controller controls the fan assembly 3 to operate for a third preset time (2S), the cover 132 of the dust cup is closed, and the emptying procedure is completed at this time.

The simple flow of the evacuation procedure is:

1. the suction motor 21 works alone (uncovering and emptying most of the dirt);

2. the suction motor 21 and the fan assembly 3 are operated simultaneously one or more times (to evacuate stubborn dirt);

3. the fan assembly 3 operates alone (closes the lid).

Referring to fig. 5-10, and also to fig. 1-4, the dirt cup assembly 1 will now be described in detail.
