Description

Technical Field

[0001] This utility model relates to the field of cleaning equipment technology, and in particular to a portable vacuum cleaner. Background Technology

[0002] Portable vacuum cleaners are small vacuum cleaners that can be used in both homes and cars. They meet people's needs for vacuuming small areas such as crevices in the car, desktops, and keyboards. They are compact in size and easy to carry and store. Users can hold them directly on the outside of the main body without the need for a separate handle.

[0003] Currently, portable vacuum cleaners on the market suffer from poor grip and difficulty in handling due to the large size of the product, especially among female users or those with smaller hands. Furthermore, the limited dust collection capacity often leads to reduced airflow, causing the machine to overheat or trigger overheat protection. Ultimately, this results in a short product lifespan, high operating costs, a poor user experience, and inconvenience for carrying around.

[0004] However, because the internal components of the product need to have sufficient assembly space, the design dimensions often conflict with the user experience. In order to balance both, it is urgent for technicians in this field to develop a portable vacuum cleaner that is simple in structure, small in size, has a large air intake, long service life, good user experience, and is easy to use.
