Vacuum cleaning devices include foldable wands to provide a storage configuration and/or facilitate use. A vacuum cleaning device includes a wand having a first end coupled to a vacuum unit and a second end coupled to a vacuum head or surface cleaning head. The wand defines an air passage allowing air to pass from the surface cleaning head to the vacuum unit and includes a flexible air passage along at least a portion of the wand. The wand also includes a plurality of segments pivotably connected together such that the wand is foldable about 180? in a forward direction until the vacuum unit is positioned proximate a top of the surface cleaning head, thereby providing a storage configuration.

Disclosed are a clamping-type dust suction tube of a vacuum cleaner and a hand-held vacuum cleaner. The clamping-type dust suction tube includes a tube body and a conductive assembly arranged within the tube body, the tube body includes a plurality of sub-tubes connected in a butt joint manner to form a whole tube, joints arranged at joint portions of every two sub-tubes, and locking mechanisms arranged on the joints and used for locking every two sub-tubes with respect to each other, wherein the length of each sub-tube is less than or equal to a length, a width or a height of other components of the vacuum cleaner. The whole clamping-type dust suction tube is convenient for assembly and carry, reduces the volume of the package, and in addition, it is simple in structure, convenient to implement, and low in cost.

A vacuum cleaner having a handle, a dirt separator and suction motor on the handle, and a nozzle. An elongated suction inlet passes through the bottom face of the nozzle, and a pivot joins the nozzle to the handle at a pivot axis that extends parallel to the elongated suction inlet. The pivot includes first and second pivot connections joining the base to either side of the handle. A base air passage extends from the suction inlet to the first pivot connection, and is fluidly connected, through the first pivot connection, to a first handle air passage located in the handle and extending from the first pivot connection to an inlet of the separator. A second handle air passage located in the handle extends from the separator outlet to the suction motor inlet.

A wand includes a hinge configured to pivotally connect first and second wand segments in an extended configuration and a storage configuration. A first locking mechanism locks the wand in extended configuration. A second locking mechanism includes a rod, a sliding lever, a plunger, and a plunger cavity. The plunger is configured to be received in the plunger cavity to lock the wand in the storage configuration. When in the extended configuration, depressing a single actuator pivots the locking arm, causes the hook/pawl to be removed from the locking cavity, and unlocks the wand. When in the storage configuration, depressing the single actuator causes the rod to move in a first direction, causes the sliding rod to move a second direction, and urges the plunger out of the plunger cavity.

A pivoting and swiveling floor treatment appliance includes a lock-prevention member that prevents a body from becoming pivotally locked in a forward/backward direction when a portion of the body is in a swiveled position. The lock-prevention member may move relative to an appliance head and to a portion of the body that swivels. In some embodiments, components of the lock-prevention member contribute to locking the swivel of the body when the body is pivotally locked.

The present application discloses an intelligent adsorption device and method for garbage, the device including: a hollow box body and an upper cover covering an upper end of the box body, where an accommodating cavity is formed in a middle portion of the box body, a storage box is inserted in the accommodating cavity, a PCB assembly is disposed at an upper end of the accommodating cavity, and a vacuumizing device and an outer air pipe are communicatively disposed at a lower end of the accommodating cavity. According to the present application, miniature garbage is adsorbed under negative pressure generated by the vacuumizing device, and an operation state of the vacuumizing device is automatically controlled through cooperation with the sensing device, which not only achieve high detection precision, but also obtain a high level of intelligent automation, a simple and compact overall structure, and a good application prospect.

A vacuum system comprising a storage tray, a vacuum assembly, and a hose. The storage tray defines a storage chamber comprising an inlet portion defining a storage chamber inlet, an outlet portion defining a storage chamber outlet, a first portion in communication with the inlet portion, a second portion in communication with the outlet portion, and an intermediate portion in communication with the first and second portions. The intermediate portion is configured such that the first and second portions are adjacent to each other. The vacuum assembly is operatively connected to the storage chamber outlet. When the hose is in a stored position, at least a portion of the hose is arranged within the first portion, the intermediate portion, and the second portion of the storage chamber. When the vacuum system is in use, at least a portion of the hose is arranged outside of the storage chamber.

A vacuum hose system has a tray assembly and a hose. The tray assembly is made of a first tray defining a plurality of first tray cavity surface portions, a middle tray defining a plurality of first middle cavity surface portions and a plurality of second middle cavity surface portions, and a second tray defining a plurality of second tray cavity surface portions. The first tray engages the middle tray to define a first portion of a storage chamber. The second tray engages the middle tray portion to define a second portion of the storage chamber. First and second reference planes extending through the first and second portions of the storage chamber are offset from each other. When the hose is in a stored position, at least part of the hose lies in each of the first and second portions of the storage chamber.
