Multi-dust-throwing-opening structure of dust collection cup of dust collector

Abstract

The invention discloses a multi-dust-throwing-opening structure of a dust collection cup of a dust collector, and belongs to the technical field of dust collectors. The multi-dust-throwing-opening structure comprises a dust cup top cover, a cyclone cone assembly, the dust collection cup and a dust collection cup bottom cover assembly. The cyclone cone assembly comprises a cyclone cone and a filter screen, wherein the cyclone cone is connected to the dust cup top cover, the filter screen is arranged on the cyclone cone in a sleeving mode, and a mounting groove is formed in the dust cup top cover; the motor is mounted in the mounting groove; the dust cup top cover is clamped to the inner side of the dust collection cup; a first dust collection chamber and a second dust collection chamber are arranged on the dust collection cup; the cyclone cone assembly is located in the first dust collection chamber; a first dust throwing opening and a second dust throwing opening are formed in the bottom of the first dust collection chamber and communicated with the second dust collection chamber; the dust collection cup is further provided with an air inlet; a dust blocking piece is arranged at the bottom of the dust collection cup and connected to the bottom cover in a clamped mode; and the sealing strip is connected between the dust collection cup and the bottom cover. Filtering pressure of the cyclone cone assembly of the dust collector can be reduced, the dust separation effect is enhanced, and the dust collection amount of the dust collection cup is increased.

Description

technical field [0001] The invention belongs to the technical field of vacuum cleaners, and in particular relates to a structure with multiple dust ejection openings for a dust collection cup of a vacuum cleaner. Background technique [0002] When the vacuum cleaner is in use, the suction motor will generate negative pressure suction, and the dusty gas will be sucked into the dust cup through the ground brush and / or straight pipe to be filtered through the filter assembly. After the dusty gas is filtered by the filter assembly of the vacuum cleaner, the separated dust particles will fall into and stay in the dust cup. Under the action of negative pressure suction, the dust particles retained in the dust collection cup will spiral upwards and may be transmitted to the filter assembly for filtering again, reducing the filtration efficiency and increasing the filtration pressure of the filter assembly. [0003] At the same time, the dust separation effect of the dust cup is po...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to solve the problem that dust is repeatedly filtered due to the structure of the dust cup in the existing vacuum cleaner, and the pressure of the filter assembly is increased. At the same time, the separation effect of the dust cup on the dust is poor, resulting in a small amount of dust collected by the dust cup and frequent dumping of dust.
