AI Technical Summary
When cleaning the bottom of the furniture, existing vacuum cleaners require users to bend over for a long time, resulting in fatigue of the back and neck muscles, and the long rods are prone to bump into the bottom edge of the furniture, resulting in wear or bend.
A foldable vacuum cleaner is designed to allow the vacuum head and connecting pipe to fold at a 90° angle by connecting and positioning components, and fixing the folding angle using a spring mechanism, ensuring that the vacuum head remains horizontal, reducing bent operations, and preventing the long rod from colliding with the edge of the furniture.
It achieves no need to bend over when cleaning the bottom of the furniture, reduces back and neck muscle fatigue, reduces the risk of long rod wear and collision, and improves the comfort of use and the durability of the equipment.

[0002] A vacuum cleaner is a common household appliance used to clean dust, dirt and debris on floors, carpets and other surfaces.
[0003] Upright vacuum cleaners are of a vertical design, easy to operate and suitable for cleaning large areas of floors. They usually have a handle and a suction head at the bottom and can be placed upright; Handheld vacuum cleaners are lightweight and portable, suitable for cleaning narrow spaces, furniture surfaces or hard-to-reach places such as inside vehicles; Barrel vacuum cleaners have a movable barrel and a flexible hose, suitable for cleaning floors and furniture surfaces, and are usually quieter than upright vacuum cleaners.
[0004] The existing vacuum cleaners commonly used in households for floor cleaning are similar in size to mops. A dust collection host is provided at the top of the vacuum cleaner, but the long rod connected between the suction head and the dust collection host is generally not bendable or foldable. When it is necessary to clean the floor under the bed, under the sofa or under other furniture, the user needs to bend down for a long time to insert the suction head under the furniture, which may cause fatigue and tension in the back and neck muscles, increase physical exertion, lead to a sense of fatigue, and the long rod of the vacuum cleaner is likely to collide with the edge of the bottom of the furniture, easily causing wear and even bending deformation on the surface of the long rod.
