Abstract

The dust collection assembly of the sweeper comprises a fan shell, a volute and a double-suction impeller, an air suction opening is formed in one side of the fan shell, and a first air outlet hole is formed in the other side of the fan shell; the volute is arranged on the fan shell, and one side of the volute communicates with the first air outlet hole. A first air inlet is formed in one end of the volute, and a second air inlet is formed in the other end of the volute; the double-suction impeller is arranged in the volute, and the first fan blade and the second fan blade are correspondingly arranged on the two sides of the middle plate. And air entering from the air suction opening flows into the first fan blade from the first air inlet, flows into the second fan blade from the second air inlet, and finally flows out from the first air outlet hole. The double-suction impeller is equivalent to two impellers which are connected in parallel, that is, the two impellers rotate at the same time, the generated air volume is equivalent to the air volume generated by two fans, and compared with a single fan blade of a single fan, the double-suction impeller generates double air volume at the same rotating speed, so that the noise is low; compared with two single fans, the double-suction impeller is small in occupied space.

Description

technical field [0001] The present invention relates to the field of cleaning technology, in particular to a vacuuming assembly of a sweeper and a sweeper. Background technique [0002] The blower of the sweeper is used as a power component for vacuuming, and its working efficiency plays a decisive role in the vacuuming of the sweeper; the existing sweeper generally uses a single suction high-speed fan with a single fan and a single blade. To achieve the best vacuuming effect, a high speed is required to increase the suction and air volume, which will cause a lot of noise; in addition, two fans are used, but the space is large, the cost is high, and it is not easy to achieve. SUMMARY OF THE INVENTION [0003] The main purpose of the present invention is to provide a dust suction assembly for a sweeper and a sweeper, aiming at solving the technical problems of large noise and large space occupied by the fan. [0004] For achieving the above object, the present invention ad...
