Vacuum cleaner main machine and vacuum cleaner

Abstract

The invention provides a vacuum cleaner main machine and a vacuum cleaner. The vacuum cleaner main machine comprises a filter device, an exhaust device, an electric control assembly and a power supplybattery. The filtering device comprises a dust bucket, a bottom cover and a dust filter, and the dust filter comprises a lower filter part and an upper filter part. A plurality of air inlet holes areformed in the side wall of the lower filter part, the lower filter part is internally provided with a plurality of inverted cone holes, dust discharge outlets are formed in the bottom of the invertedcone holes, and the inverted cone holes and the air inlet holes are arranged in a one-to-one correspondence mode. The lower filter part is further internally provided with an isolation inner sleeve,and the upper filter part is internally provided with a fine filter element. The exhaust device comprises an exhaust shell, a motor assembly, a noise reduction cover and soundproof cotton. The vacuumcleaner is provided with the vacuum cleaner main machine. According to the vacuum cleaner main machine and the vacuum cleaner, by arranging the filter device on the vacuum cleaner main machine, the good dust separation function can be realized, and higher dust removal and mite removal rate is provided; and by arranging various sound reduction structures in the exhaust device, the effective noise reduction function can be played on the operation of motors and the airflow, and thus the use effect of a user is better.

Description

technical field [0001] The invention relates to the field of vacuum cleaners, in particular to a main engine of a vacuum cleaner and a vacuum cleaner. Background technique [0002] The vacuum cleaner is an important tool for household or public environment cleaning. The working principle of the vacuum cleaner is: after the suction head is placed on the area to be cleaned, the vacuum cleaner generates an airflow, and debris and debris are entrained in the airflow and then brought into the dust. In the dust cup, sundries and debris accumulate in the dust cup for further processing. [0003] Hand-held vacuum cleaners are commonly used household vacuum cleaners, because hand-held vacuum cleaners are smaller in size and lighter in weight than horizontal and bucket vacuum cleaners. In addition, they can be converted into upright vacuum cleaners when equipped with a nozzle and a floor brush, which is suitable for cleaning household hygiene. By the majority of consumers of all ages...

AI Technical Summary

Problems solved by technology

In order to reduce secondary pollution, existing vacuum cleaners continuously improve the separation efficiency, and the structure of the dust cup is correspondingly more and more complicated. The size of the dust cup is larger, but the effective dust collection capacity is smaller, and the size of the whole machine is larger. The suction power is weakened, and there is no effective sound-reducing structure, resulting in too high decibels during use, which affects the user experience
