[0002] With the rapid development of the economy, consumer income continues to grow, especially the rapid growth of income levels of residents in large and medium-sized cities. Residents' living conditions continue to improve, and there are more and more duplex houses and large-area houses. Residents' demand for vacuum cleaners is also getting stronger. The working principle of a vacuum cleaner is to use an electric motor to drive the blades to rotate at high speed, generate negative air pressure in a sealed shell, and absorb dust.
[0003] The shortcomings of the prior art: Vacuum cleaners in the prior art usually use motors to drive blades to rotate at high speed to generate negative air pressure for dust collection. However, when the blades rotate at high speed, the large air pressure will generate large noise in a small space. At the same time, when the blades collide with the body during the process of sucking dust, it will also generate certain noise. Therefore, it will cause certain noise pollution to the surrounding environment when in use. Utility Model Content
