Abstract
Description
Technical Field
[0001] The utility model relates to a bent tube and a vacuum cleaner with the bent tube, belonging to the technical field of cleaning household appliances. Background Art
[0002] With the continuous advancement of vacuum cleaner technology, users have placed higher demands on the flexibility and ease of use of vacuum cleaners. The design of the bending tube came into being to meet these needs. Users hope that the vacuum cleaner can easily clean hard-to-reach areas, such as under furniture, in corners, etc. The bending tube provides a solution that can be achieved without additional tools or accessories. It allows the nozzle part of the vacuum cleaner to bend and turn without adding additional mechanical parts. Some existing brands of vacuum cleaners use flexible hoses that allow users to bend manually to adapt to different cleaning needs. Some brands of vacuum cleaners use retractable hard tubes that use a built-in telescopic mechanism to adjust the length and bending angle. Some brands of vacuum cleaners use universal joints that allow multi-angle rotation and bending. However, the design of existing bending tubes may limit the bending angle and cannot meet some cleaning needs. Frequent bending of the bending tube may cause material fatigue and affect the durability of the product.
[0003] The patent with authorization announcement number CN 201948942 U discloses a vacuum cleaner elbow, which includes a bend body, a hose connector embedded in the bend body, a clamp whose upper end face is sealed with the lower end face of the hose connector, and a button arranged between the bend body and the clamp. The clamp includes an arc segment located in the bend body and a straight segment extending out of the bend body. The straight segment has multiple strip openings at different axial lengths, and the multiple strip openings all extend along the circumference of the straight segment. This spring-like structure design enables the straight segment to produce a recoverable deformation within a certain range. When the straight segment of the clamp is squeezed from different angles by the hose, it can produce a recoverable deformation that adapts to the bending direction of the hose and fits with the hose at the squeezed part. This not only facilitates the vacuum cleaner's dust collection, but also balances the force on the hose surface, preventing the hose from bending, deforming, or breaking. However, the bending angle of the vacuum cleaner elbow of this utility model may be limited, and the volume is also relatively large. Utility Model Content
