A classification device includes a hose configured to suck dust containing fine dust and foreign matter, a body defining a classification space therein, connected to the hose, including an upper discharge port and a lower discharge port, the upper discharge port being provided in an upper portion of the body so as to be connected to a suction device, and the lower discharge port being provided in a lower portion of the body, a lid member configured to be mounted on a container defining a storage space for storing the foreign matter discharged from the lower discharge port of the body, including an air intake configured to communicate with the storage space, and positioned below the body, and an air introduction pipe connected to the air intake of the lid member and configured to be disposed in the storage space.

The gardening apparatus (100) for blowing and sucking plant material comprises an engine or motor (20) adapted to operate in a first direction of rotation and a second direction of rotation and a housing (10) in which an impeller (30) is mechanically connected to the engine or motor (20). The housing (10) comprises a first opening (41) and a second opening (51) and the impeller (30) is adapted to generate a first air flow from the first opening (41) and exiting from said second opening (51) when the engine or motor (20) is operating according to the first direction of rotation and to generate a second air flow entering from the second opening (51) and exiting from said first opening (41) when the engine or motor (20) is operating according to the second direction of rotation. In this way, it is possible, for example, to extract air from a container (80) fixed to said second opening (51) and thus reduce the volume of the container (80) with plant material inside.

The present disclosure relates to a self-cleaning dust-collecting base and a dust-collecting system. The self-cleaning dust-collecting base includes a self-cleaning dust-collecting base body, and the self-cleaning dust-collecting base body comprises: a dust-collecting cavity, an opening of which is arranged upwards and forwards at a top end of the self-cleaning dust-collecting base body; and a dust-collecting cover, which is detachably buckled onto the dust-collecting cavity to form a dust-collecting bin for accommodating a rubbish accommodation device, wherein at least a portion of the outer surface of the dust-collecting cover acts as a portion of the exterior surface of the self-cleaning dust-collecting base.

Provided is an automatic cleaning device. The automatic cleaning device includes: a mobile platform configured to automatically move on an operation surface and including an accommodating chamber, the accommodating chamber including a first chamber and a second chamber; and a cleaning module comprising a dust box detachably assembled to the accommodating chamber. The first chamber and the second chamber are sequentially arranged next to each other in an advancing direction of the automatic cleaning device, and a depth of the first chamber is greater than a depth of the second chamber.

A vacuum cleaner is described herein that uses an elongated design that provides the various vacuum components along nearly an entire length of the vacuum cleaner and in-line with one another. According to some embodiments, at least one waste receptacle, a filter structure, and a motor are each axially aligned with a longitudinal central axis of a body of the vacuum cleaner. An air suction inlet may also be arranged at a distal end of the body and axially aligned with the longitudinal central axis. In some examples, the body maintains a substantially constant diameter along its entire length.

A closure device for closing a particle capture volume, in particular a bag or a container, including an access element with an access element opening for providing an access to the particle capture volume, a closure slide which can be selectively displaced relative to the access element into a release position or into a closure position. In the release position the closure slide releases the access element opening and in the closure position closes the access element opening, and a locking mechanism for locking the closure slide in the closure position with respect to the access element, where the locking mechanism 6 for unlocking requires a defined unlocking element which is separate from the locking mechanism.

A dust collection device may include a support plate including an opening through which dust is introducible, a protruding rib extending downward from a circumference of the opening of the support plate, and an opening/closing device couplable to the support plate. The opening/closing device may include an opening/closing cover configured to open and close the opening of the support plate, while the opening/closing device is coupled to the support plate, and a cover rib protruding from an upper surface of the opening/closing cover and configured to contact the protruding rib while the opening of the support plate is closed by the opening/closing cover.

A vacuum cleaner is described herein that uses an elongated design that provides the various vacuum components along nearly an entire length of the vacuum cleaner and in-line with one another. According to some embodiments, at least one waste receptacle, a filter structure, and a motor are each axially aligned with a longitudinal central axis of a body of the vacuum cleaner. An air suction inlet may also be arranged at a distal end of the body and axially aligned with the longitudinal central axis. In some examples, the body maintains a substantially constant diameter along its entire length.

The present disclosure relates to a dust collection device, including a dust collection body and a dust collection box inserted into the dust collection body, where the dust collection body has a connecting part for accommodating the dust collection box; an outer surface of one of a buckle plate of the dust collection box and a first side wall of the connecting part is provided with protruding parts higher than a sealing gasket, and the other one is provided with clamping grooves recessed inwards along an outer surface and matched with the protruding parts; and when the dust collection box is inserted into the dust collection body, the protruding parts slide along the outer surface of one of the first side wall and the buckle plate, such that the friction between the first side wall or the buckle plate and the sealing gasket can be isolated.

A filtering device for an evacuation station includes a filter bag configured to collect debris evacuated from a cleaning robot by an evacuation station. The filtering device includes an interface assembly configured to interface with the evacuation station. The interface assembly includes (i) a base attached to the filter bag along an opening of the filter bag, (ii) an access door configured to provide or limit access to a space within the filter bag depending on whether the access door is in an open position or a closed position, and (iii) one or more hinges connecting the base to the access door. The access door is rotatable around the one or more hinges from the closed position to the open position.
