Description

Technical Field

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

[0002] Vacuum cleaners are an indispensable cleaning tool in modern life. They can quickly and efficiently remove dust, dirt, and small particles from homes, offices, and cars, making the environment fresher and healthier. However, different types of vacuum cleaners are suitable for different scenarios.

[0003] Portable vacuum cleaners are small vacuum cleaners that can be used in both homes and cars, meeting people's needs for vacuuming small areas such as crevices in cars, desktops, and keyboards.

[0004] Some portable vacuum cleaners currently available have a handle and a vacuuming module connected to the handle. The handle and the vacuuming module generally extend in different directions, such as a T-shaped portable vacuum cleaner. The T-shaped portable vacuum cleaner has a complex structure and large size, resulting in a large space occupied by the whole machine. Because the handle cannot be folded, it is inconvenient for users to store, resulting in a poor user experience. In addition, the waste of packaging space leads to higher packaging and transportation costs.

[0005] Currently, T-shaped portable vacuum cleaners on the market are limited in application scenarios due to their short length and the fact that the handle requires an external power source or cannot be effectively utilized due to the built-in power source. They are also inconvenient to store, resulting in a poor user experience, and there is a need to improve them.

[0006] This utility model has a simple structure and compact design. The handle can be folded inward or outward, taking up little space, with low cost, wide range of applications, and a better user experience. Utility Model Content
