Background

Many of the vacuum cleaning devices on the market, including vacuum cleaners, floor washers and the like, have vacuum nozzles. Dirt is collected by the air flow and brush for removal of the stain. And transporting the dirt into the dirt container, while the remaining airflow exits the apparatus through the vacuum source. However, at present, a single air flow channel can only collect dirt in a dirt container, the dirt cannot be transferred from the dirt container, and the dirt container is mostly required to be manually contacted during cleaning. Taking a dust collector as an example, after the dust collector sucks dirt into the dust cup, a user is required to take down the dust cup and pour the dirt into the garbage can.

At present, in order to solve the pain point that the dirt container needs to be manually taken down for cleaning, a dust collector base station appears on the market. For example, 201680018767.5 provides a vacuum cleaner base station, a vacuum cleaner system, and a method for controlling a vacuum cleaner base station, in which a stick-type vacuum cleaner having a dust collecting cylinder mounted therein is coupled to a base station, a dust collecting motor is provided in the base station, dirt is sucked into the vacuum cleaner by using a suction motor (provided in the vacuum cleaner) as a vacuum source, and dirt in the vacuum cleaner is transferred into the base station by using the dust collecting motor (provided in the base station) as a vacuum source. The dust collection system and the dust exhaust system are controlled by different vacuum sources respectively, and the base stations on the market at present are all provided with independent vacuum sources to realize the normal operation of the dust exhaust gas circuit.

In addition, the applicant also considers that when the dust cup is in butt joint with the dust collecting station in the structure, the dust cup is required to be manually opened and then is spliced with the interface of the dust collecting station, so that the structure is more complicated. It is therefore desirable to provide a mechanical switching mechanism that automatically opens and closes the door.
