[0002] In household cleaning, it is necessary to thoroughly clean the dirt inside the house, but the traditional method cannot meet the indoor cleanliness requirements and is time-consuming and labor-intensive. Vacuum cleaners can effectively solve these problems. Vacuum cleaners are household appliances that use electricity to suck in air to suck in smaller garbage or dust and fill it into the dust collection bucket inside the product.

[0003] Chinese invention patent CN112704428A discloses a dust cup assembly and a handheld vacuum cleaner, comprising: a dust cup body, the bottom of which is provided with a cleaning opening; a dust cup end cover, movably connected to the cleaning opening; a slider assembly, the slider having a locking position close to the dust cup body and an unlocking position away from the dust cup body, and at least a portion of the dust cup end cover is located on the sliding path of the slider assembly. The bottom of the dust cup body is provided with a cleaning opening, so that dust and dirt retained in the dust collection cavity can fall off when the dust cup end cover is opened.

[0004] But the problem is that the dust cup end cover of the above patent requires the user to manually open the dust cup end cover to discharge dust, which is inconvenient. Therefore, this patent designs a handheld vacuum cleaner that can be docked with an external base station. The vacuum cleaner can be docked with the external base station to automatically discharge dust, making it convenient for the vacuum cleaner to discharge dust. Utility Model Content
