Technical Field

[0001] This utility model belongs to the field of vacuum cleaner technology, specifically relating to a handheld vacuum cleaner with a hidden charging port. Background Technology

[0002] Vacuum cleaners, as a household cleaning tool, are widely used in people's lives because they can automatically collect dust and debris from different locations such as floors and furniture. Vacuum cleaners include different types such as canister vacuum cleaners, upright vacuum cleaners, and handheld vacuum cleaners. Among them, cordless handheld vacuum cleaners (for convenient vacuuming) are popular because they have built-in batteries and are compact, lightweight, flexible, and versatile.

[0003] For easier charging, existing handheld vacuum cleaners typically place the charging port on the outside of the casing. However, during storage and use, dust can easily enter and contaminate the charging port, affecting its lifespan. Additionally, dust can enter the electrical components inside the vacuum cleaner casing through the external charging port, potentially affecting their sensitivity. This can cause the conventional push-button switch to malfunction, leading to users forcefully pressing and damaging the vacuum cleaner. Furthermore, having the charging port on the outside of the casing also negatively impacts the vacuum cleaner's aesthetics. Utility Model Content
