Dust is generally the most unpleasant thing for people during cleaning, and not only can affect indoor cleaning and the influence on equipment such as electric appliances, but also can harm the respiratory system of people and hurt the health of human bodies. The dust collector can collect dust through strong suction airflow, and is convenient to clean and arrange, so that the dust collector becomes a good helper for cleaning and relaxing housework, and becomes an electric appliance necessary for many families.
The european union issued regulations on vacuum cleaner ecological design requirements that require vacuum cleaners to meet the following requirements since 2017, 9, month 1: the annual power consumption should be less than 43.0kWh/year, the rated input power should be less than 900W, the dust absorbed on the carpet should be greater than or equal to 0.75um (not suitable for a hard floor cleaner), the dust absorbed on the hard carpet should be greater than or equal to 0.98um (not suitable for a hard floor cleaner), the dust re-release rate should not exceed 1.00%, the sound power level should be less than or equal to 80dB, the hose can still be used after 40000 times of vibration under stress, and the service life of the operating motor should be greater than or equal to 500 hours.

The middle part of the upper impeller blade is provided with an air suction opening, when the movable impeller rotates, air in the movable impeller is discharged due to the action of the blades to generate strong negative pressure to generate vacuum, and high negative pressure difference is formed between the air and external atmospheric pressure. The external air is continuously sucked into the movable impeller from the air suction opening under the action of pressure difference and then is discharged by the blades, and then flows out of the electric fan through the air guide disc to form a complete air suction working process.
In the prior art, because the wind blade and the upper and lower impeller blades are connected by adopting a riveting process, a riveting gap exists among the wind blade, the upper impeller blade, the lower impeller blade and the upper impeller blade, when the movable impeller rotates at a high speed, airflow is sucked into an air suction channel in the inner space of the movable impeller, a small part of airflow flows out from the gap, the adjacent channels are influenced mutually to generate vortex, the vacuum degree and the air flow of the electric fan are reduced, and the output and the working efficiency of suction power are reduced. In addition, if the electrophoretic coating is not uniform, the local weight of the whole movable impeller is higher, and in order to balance the weight on the circumferential surface, a balance detection process and a lower impeller sheet shearing operation process on the heavier side are required to be added, so that the working strength and the manufacturing cost are increased, and meanwhile, in case that the weight balance is not ensured, the working efficiency of the movable impeller can be influenced during normal operation, and how to completely eliminate the riveting gap becomes one of hot topics in the field.
