Problems solved by technology

[0003] However, the suction brush connected to the conventional extension tube has a disadvantage in that in order to clean the space under furniture such as beds and sofas, the user must adopt a low posture to bring the suction brush into close contact with the cleaning surface, because the extension tube and the suction The angle between the brushes is usually not adjustable
Also, even though the angle between the extension tube and the brush is adjustable, the user still has to bend over to push the brush further into the space under the furniture

Embodiment Construction

[0017] Embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0018] figure 1 and figure 2 Respectively, a perspective view and an exploded perspective view for showing an extension pipe with a joint for a vacuum cleaner according to a preferred embodiment of the present invention. The extension pipe includes a first extension pipe 110 connected to the main body of the vacuum cleaner (not shown), and a second extension pipe 120 bendably connected to the first extension pipe 110 and connected to a suction brush (not shown). Suction brush self-cleaning surface suction. The first extension pipe 110 and the second extension pipe 120 are pivotally connected to each other by a separation prevention cover 130 . The pivotal movement of the second extension pipe 120 relative to the first extension pipe 110 may be adjusted by the locking unit 140 hingedly connected to the first extension pipe 110 .

Abstract

An extension tube for a vacuum cleaner with a joint for forming a sealed duct between a cleaner body and a suction brush and having a bendable portion selected by the user. The extension tube includes: a first extension tube; a second extension tube pivotably connected to the first extension tube; at least one separation preventing cap penetrating the first and second extension tubes from outside the first extension tube; and A locking unit hingedly connected to the first extension pipe. The locking unit hooks the second extension tube and optionally locks the pivotal movement of the first and second extension tubes. In addition, the locking unit releases the locking of the second extension tube so that the first and second extension tubes can be bent.

Description

technical field [0001] The present invention relates to a vacuum cleaner, and in particular, to an extension tube for a vacuum cleaner having a curved connection portion to facilitate cleaning on spaces under furniture such as beds and sofas. Background technique [0002] Generally, the vacuum cleaner uses the vacuum suction force generated by the vacuum suction motor provided in the main body of the vacuum cleaner to self-clean the surface to suck the surrounding air together with the dust. The vacuum cleaner has a duct connected between the cleaner main body and the suction brush in a sealed state. The duct can take different forms according to the type of vacuum cleaner. Generally, a cylindrical vacuum cleaner includes a flexible tube for connecting the main body of the vacuum cleaner and the handle, and an extension tube for connecting the handle and the suction brush. The extension tube is expandable, retractable, and adjustable in length. Multiple extension tubes are...
