Description

Technical Field

[0001] The utility model relates to the field of cleaning equipment, in particular to a vacuum cleaner which is easy to seal. Background Art

[0002] A vacuum cleaner is a household appliance used to clean dust and debris on the floor, carpet, furniture and other surfaces. The components of a vacuum cleaner generally include a motor, an air inlet channel, a HEPA component, a dust cup, etc. Its working principle is to use a motor to generate a strong suction force to suck dust and debris into the vacuum cleaner and store them in the dust cup. However, in the prior art, during use, the wind in the vacuum cleaner is prone to leakage between adjacent components during the flow, especially between the dust cup and the HEPA component. Since the dust cup and the HEPA component are usually connected in abutment, the vacuum cleaner often overflows the airflow through the gap between the dust cup and the HEPA component when filtering dust, which not only increases wind loss and reduces the vacuum cleaner's dust collection efficiency, but also leads to insufficient suction and air leakage, so that dust and particles may leak through gaps or holes, affecting the cleaning effect and causing secondary pollution, making the indoor air quality worse, so that users need to spend a lot of time and effort to disassemble and clean components such as the dust cup and filter, which seriously affects the user's experience and the cleaning effect of the vacuum cleaner.
