[0002] As a crucial component of vacuum cleaner technology, the lifting mechanism plays a crucial role in enhancing the convenience, practicality, and user experience of vacuum cleaners. With the continuous advancement of technology and market development, the design of the lifting mechanism will continue to be optimized and improved, providing users with a more efficient, convenient, and intelligent cleaning experience.

[0003] The prior art has specially developed some height-lifting structures for vacuum cleaners. For example, the Chinese patent with the announcement number "CN209003811U" discloses a "vacuum cleaner lifting and rotating structure". Through the design of the lifting and rotating structure, the structure is simple and easy to use. The overall height of the vacuum cleaner can be greatly reduced by flipping, which is convenient for installation and transportation; ensuring the safety of transportation and use.

[0004] Although the overall height of the vacuum cleaner can be greatly reduced by flipping, which facilitates installation and transportation, and ensures safe transportation and use, lowering the overall height of the vacuum cleaner by flipping it in a smaller space will cause the vacuum cleaner and the dust bucket to be unable to be effectively flipped, and need to be moved to a larger space for flipping, which will cause inconvenience to the staff.
