After the base station is triggered, on the one hand, the negative pressure component generates suction, and on the other hand, the battery pack of the vacuum cleaner is charged through the charging component 15, and the battery pack controls the electromagnet 26 to cut off power, further unlocking the dust cup bottom cover 24.

After suction is generated in the base station, the bottom cover 24 of the dust cup rotates and opens under the action of suction, so that the dust in the dust collection chamber 23 is sucked into the base station through the dust suction channel 12 . After the base station works for a period of time (specifically, it can be set to about 20 seconds), it stops working, the electromagnet is energized, the dust cup bottom cover 24 is reset under the action of the torsion spring, and the electromagnet 26 absorbs the iron block 243 to realize the bottom cover of the dust cup. The cover 24 is locked, and the dust cup bottom cover 24 is closed in place.

When the vacuum cleaner is separated from the base station, the release button 25 is reset under the elastic force of the return spring and hooks the dust cup bottom cover 24 to prevent the dust cup bottom cover 24 from opening in the event of a drop or collision during use.

In actual implementation, after the control base station is triggered, the set negative pressure component is turned on, and the battery pack starts to be energized. The trigger of the battery pack being powered on will control the electromagnet 26 to be powered off. The negative pressure component is set to work for a specific working time T1, and the electromagnet 26 is Set the power-off time T2. When the power-off time T2 ends, the battery pack returns to the electromagnet power supply. By setting the power-off time T2 equal to the working time T1, the negative pressure component can be turned on, the electromagnet 26 can be powered off, the negative pressure component can be turned off, and the electromagnet can be energized.
