Vacuum cups and vacuum cleaners

Abstract

The invention provides a dust cup for a dust collector and the dust collector. An air inlet channel, a first-order cyclone separation cavity, a first-order dust collection cavity, an auxiliary channel, a second-order cyclone separation cavity, a second-order dust collection cavity, an air outlet channel and a filter cotton are arranged in the dust cup; the first-order dust collection cavity is arranged below the second-order dust collection cavity, the first-order cyclone separation cavity is arranged in the first-order dust collection cavity, the outlet formed in the upper end of the first-order cyclone separation cavity is communicated with the first-order dust collection cavity, the inlet of the auxiliary channel is arranged in the outlet of the first-order cyclone separation cavity, the second-order cyclone separation cavity is arranged in the second-order dust collection cavity, the outlet of the auxiliary channel is the same with the inlet formed in the upper end of the second-order cyclone separation cavity, the inlet of the air outlet channel is arranged in the inlet of the second-order cyclone separation cavity, the outlet formed in the lower end of the second-order cyclone separation cavity is communicated with the second-order dust collection cavity, and the filter cotton is arranged in the air outlet channel. The dust cup for the dust collector has a novel small and exquisite structure and can well meet the using needs of consumers with large dust collection capacity of the first-order dust collection cavity.

Description

technical field [0001] The invention relates to the field of home appliances, and more specifically, to a dust cup of a vacuum cleaner and a vacuum cleaner. Background technique [0002] Dust cups for vacuum cleaners of existing designs, such as figure 1 As shown, the dust-laden air enters the first-stage cyclone separation chamber 2' from the air intake channel 1', and rotates in the cyclone separation chamber to generate centrifugal force to separate the dust and gas. After separation, the dust (ie: garbage) falls into the first-stage dust collection chamber 3', the dusty air enters the secondary cyclone separation chamber 5' through the auxiliary channel 4' for secondary dust and gas separation, and the garbage falls into the secondary dust collection chamber 6' through the lower opening of the cyclone separation chamber, and the dusty air is then passed through The air outlet channel 7' is discharged, filtered through the filter cotton 8', and finally discharged into th...

AI Technical Summary

Problems solved by technology

[0004] When light-weight and bulky garbage enters the first-stage cyclone separation chamber 2', most of the garbage will quickly enter the first-stage dust collection chamber 3', and rotate and accumulate along the inner wall of the dust cup. When the garbage gradually accumulates , the garbage will easily overflow the lip 9' of the dust plate, and return to the primary cyclone separation chamber 2' to continue to rotate. When the rotating garbage gradually increases, the entrance of the auxiliary channel 4' will be easily blocked, causing the vacuum cleaner to The suction decreases, which in turn causes the rotation speed of the garbage to decrease, and the entrance of the auxiliary channel 4' is blocked to further accelerate, and soon there is no suction, and it can no longer be used, resulting in a large reduction in the dust collection capacity of the first-stage dust collection chamber 3'. If you want to expand The dust collection capacity needs to increase the size of the dust cup, which makes the whole machine too large and clumsy
