Technical Field

[0001] The utility model relates to the technical field of vacuum cleaners, in particular to a vacuum cleaner nozzle structure for slits. Background Art

[0002] Vacuum cleaners are a relatively common small household appliance. Nowadays, more and more vacuum cleaners have entered people's lives. Vacuum cleaners are very useful and have significant effects in cleaning. The suction nozzle of the vacuum cleaner plays a very critical role in the vacuum cleaner. When the vacuum cleaner is working, different suction nozzles need to be replaced for vacuuming in different areas.

[0003] When vacuuming some narrow gaps with existing vacuum cleaners, it is necessary to replace the vacuum nozzle with a flat-mouth type to perform the vacuuming work. However, when replacing and installing the suction nozzle of some vacuum cleaners, most of them are directly mounted on the end of the dust suction tube, which causes the suction nozzle to be easily stuck in the narrow gap when inserted into the narrow gap for vacuuming, and easily fall off from the end of the dust suction tube when pulled out, affecting the operation of the vacuum cleaner. Secondly, some of them install and fix the suction nozzle body by screwing the threaded sleeve, which makes the disassembly and assembly process of the suction nozzle more cumbersome. In view of the above problems, the inventor proposes a vacuum cleaner nozzle structure for narrow gaps to solve the above problems. Utility Model Content
