Dust removal structure with metal net filtering structure

Abstract

The invention relates to a dust removal structure with a metal net filtering structure. The dust removal structure with the metal net filtering structure comprises a dust cup, a cyclone chamber, a filtering plate, a filtering tube body, a filtering net, a separating tube body and filtering cotton; a wind inlet is formed in one side of the dust cup, and a clamping opening is formed in the dust cup;a supporting rod is arranged in the dust cup, and one end of the cyclone chamber is fixedly connected with a top rod; and the supporting rod is movably connected with the top rod in a clamped mode, and the filtering plate is connected to the outer side of the cyclone chamber. The dust removal structure has the beneficial effects that multi-stage filtering is set in the dust cup, as for primary filtering, the filtering plate is adopted creatively, a metal filter net is adopted as the filtering plate, and thus the filtering plate has the characteristics that washing is easy, and fine particlesare easy to separate; as for secondary filtering, the hole diameter of the internal filtering net is further decreased, and small dust can be filtered; and as for final filtering, the filtering cottoncan filter the fine particles, the filtering effect is good, air and the dust are separated thoroughly, the air discharged from a dust collector is cleaner, and secondary pollution is not generated.

Description

technical field [0001] The invention relates to a dust removal structure with a metal mesh filter structure, which belongs to the technical field of vacuum cleaner components. Background technique [0002] Vacuum cleaners can be divided into vertical, horizontal and portable according to their structure. The working principle of the vacuum cleaner is to use the motor to drive the blades to rotate at high speed, generate air negative pressure in the sealed housing, and absorb dust. Vacuum cleaners are mainly divided into three types: household vacuum cleaners, commercial vacuum cleaners and industrial vacuum cleaners. Dust suction principle, the fan impeller of the vacuum cleaner is driven by the motor at high speed, and the air in the impeller is discharged from the fan at high speed, and at the same time, the air in the dust collection part is continuously replenished into the fan. This may result in a higher pressure difference with the outside world. The dust and dirt ...

AI Technical Summary

Problems solved by technology

[0003] The existing separation and dust collection structure is simple to set up and cannot perform multi-stage gas-dust separation. The separation level of gas-dust is low, which easily causes secondary pollution of dust, and the efficiency of gas-dust separation is not high. The primary separation device installed on the outside is easily Larger particles of dust are clogged and self-cleaning is impossible, and the installation and positioning of each separation part is not convenient and quick enough. The subsequent dust cleaning and installation are cumbersome and not convenient enough to use
