SWIVEL JOINT FOR VACUUM CLEANER AND HANDHELD VACUUM CLEANER

摘要

A swivel joint (4) for a hand-held vacuum cleaner comprises: a first joint tube (41) and a second joint tube (42) rotatably connected at one end portions thereof with respect to each other, a connecting tube (43) enabling communication between the first joint tube (41) with the second joint tube (42) which are rotatably connected with respect to each other, and a conductive assembly (44), wherein the connecting tube (43) is a corrugated flexible tube, the other end portions of the first and second joint tubes (41, 42) respectively connect a vacuum cleaner body (1) with a dust suction tube (3) of a vacuum cleaner or the dust suction tube (3) with a dust suction head (2) of the vacuum cleaner, and the conductive assembly (44) comprises: a first conductive interface (441) and a second conductive interface (442) respectively disposed on the first and second joint tubes (41, 42); and a conducting wire disposed inside the corrugated flexible tube (43), wherein two ends of the conducting wire connect with the first and second conductive interfaces (441, 442), respectively. The provision of the swivel joint (4) enables a vacuum cleaner to be quickly placed in an upright position, allows an operator to perform multi-angle (omni-directional) dust removal with a natural posture, with much convenience, and moreover, the design of a hidden electrically-conductive assembly (44) can reduce the probability of occurrence of a line fault and extend the service life.
