Description

Technical Field

[0001] The utility model relates to the technical field of vacuum cleaner auxiliary appliances, in particular to a base station for a handheld vacuum cleaner. Background Art

[0002] Vacuum cleaner base stations are widely used as companion equipment for handheld vacuum cleaners. After use, the handheld vacuum cleaner can be docked at the base station. While docked, the handheld vacuum cleaner can be charged and its dust cup cleaned. The base station typically includes a housing, a dust filter bag, a suction motor, and a chassis. The housing is typically cylindrical, with a support portion at the top for supporting the handheld vacuum cleaner. The dust filter bag is mounted within the housing. The suction motor is mounted within the housing and located below the dust filter bag, with airflow between the suction motor and the dust filter bag connected. The chassis is typically placed on the ground and serves to support the housing. After prolonged use, a large amount of dust often accumulates in the dust cup of a handheld vacuum cleaner. Low battery levels can also affect the battery life of the handheld vacuum cleaner. Users need to empty the dust cup and charge the handheld vacuum cleaner before continuing to use it. The user usually supports the handheld vacuum cleaner on the support part on the upper part of the base station casing, and then opens the dust cup of the handheld vacuum cleaner. The suction motor on the base station generates a negative pressure airflow from the dust cup into the filter dust bag, thereby collecting the dust accumulated inside the dust cup in the filter dust bag. Traditional base stations are usually fixedly supported on the chassis, and because base stations are usually bulky, they are generally placed in a certain area and not moved. When the handheld vacuum cleaner is docked to the base station for dust collection, charging, and other operations, the posture of the handheld vacuum cleaner on the base station is relatively fixed. The user needs to move to a position where the handheld vacuum cleaner is convenient to use before manually picking up the handheld vacuum cleaner from the base station.
