Abstract: A swivel joint for a hand-held vacuum cleaner includes a first joint tube and a second joint tube rotatably connected at one end portions thereof with respect to each other, a connecting tube enabling communication between the first joint tube with the second joint tube, and a conductive assembly. The connecting tube is a corrugated flexible tube. The other end portions of the first and second joint tubes respectively connect a vacuum cleaner body with a dust suction tube of a vacuum cleaner or the dust suction tube with a dust suction head of the vacuum cleaner. The conductive assembly includes a first conductive interface and a second conductive interface respectively disposed on the first and second joint tubes and a conducting wire disposed inside the corrugated flexible tube. Two ends of the conducting wire connect with the first and second conductive interfaces, respectively.

Abstract: Disclosed are a conductive telescopic tube and a hand-held vacuum cleaner, the conductive telescopic tube includes a plurality of sleevings capable of extending-retracting with respect to each other, and conductive assemblies disposed on each of the sleevings and capable of being connected with each other, and the conductive assemblies include mounting seats disposed on one side of the sleevings along a length direction of each of the sleevings, contact strips disposed along a length direction of the mounting seat, and a conductive joint conductively connecting every two adjacent of the contact strips respectively, wherein every two adjacent of the mounting seats are telescopically disposed, two end portions of the conductive joint are respectively located within two adjacent mounting seats, and capable of always conductively connecting the two adjacent contact strips. The hand-held vacuum cleaner includes a vacuum cleaner body, a dust suction head and the conductive telescopic tube.

Abstract: 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.
