[0033] The dust cup housing 1 is provided with a dust cup air inlet 11 and a dust shield on the side, and the interior is divided into a multi-stage dust collecting cavity by a plurality of partitions 12, and the partitions 12 are provided with a connecting port 121 connecting adjacent cavities in the multi-stage dust collecting cavity:

[0034] The coarse filter assembly 2 is assembled in the dust cup housing 1 through an assembly bracket, and a filter screen is arranged on the assembly bracket:

[0035] The dust cup bottom cover 3 is embedded and assembled at the bottom of the dust cup housing 1, the coarse filter assembly 2 and a plurality of partitions 12:

[0036] The dust cup middle cover 4 is connected and positioned with the top of the coarse filter assembly 2, and a mounting frame is provided on the top, and a fine filter assembly 41 is assembled in the mounting frame;

[0037] The dust cup top cover 5 is assembled on the dust cup middle cover 4 and is provided with a dust cup air outlet 51.

[0038] The multi-stage dust collecting cavity formed by the partition 12 of the dust cup cooperates with the dust collecting cavity at the bottom of the coarse filter component 2 to separately collect dust, hair and other dirt of different particle sizes, densities, different motion trajectories and regional landing points formed by the airflow, and cooperates with the filter component to improve the filtering, interception and sedimentation efficiency of dirt, and also avoids the single dust collecting cavity design of the common dust cup, which makes it difficult for dust particles to collide frequently and settle quickly during use, and dust particles of different particle size ranges are tightly embedded, resulting in inconvenience in cleaning the dust cup.

[0039] The multi-stage dust collecting chamber includes a first dust chamber 13 in which the coarse filtering assembly 2 is arranged, and a second dust chamber 14 and a third dust chamber 15 located on the sides of the first dust chamber 13 , and the dust cup air inlet 11 faces the first dust chamber 13 .

[0040] The dust cup bottom cover 3 is provided with a first dust groove 31, a second dust groove 32 and a third dust groove 33 corresponding to the first dust chamber 13, the second dust chamber 14 and the third dust chamber 15, and a plurality of partitions 12 are correspondingly plugged into the first dust groove 31 and / or the second dust groove 32 and the third dust groove 33. Through the interlocking assembly of the dust cup bottom cover 3 and the partitions 12, the structure of the multi-stage dust collecting cavity and the stability of dust and dirt sedimentation in each dust chamber are improved.

[0041] The dust cup shell 1 is plugged into the dust cup bottom cover 3, and the coarse filter assembly 2 is plugged into the positioning structure in the first dust groove 31, thereby improving the assembly stability of the dust cup bottom cover 3, the dust cup shell 1 and the coarse filter assembly 2, thereby ensuring the efficient use of the dust cup.

[0042] The filter screen of the coarse filter component 2 is a metal mesh, and the fine filter component 41 is filter cotton or HEPA, which ensures that the filter components in each filtering stage can efficiently filter and retain dust.

[0043] The dust cup top cover 5 is provided with an aromatherapy 52 on the ventilation mesh hole connected to the inner cavity of the mounting frame 41 to add fragrance to the clean air, improve the functionality of the dust cup, and enhance the user experience.

[0044] The working principle of a dust cup with a multi-stage dust collection cavity of this embodiment includes: Figure 2As shown, in the first stage of filtration, the dust cup air inlet tangent point design is achieved through the elastic wind guide dust shield sheet at the dust cup air inlet 11, ensuring that the air has a rotating effect when entering, so that the dust has centrifugal force, and the dust with large particles settles to the bottom of the first dust chamber 13, and cooperates with the partition 12 to increase the probability of the fallen large particles being retained at the bottom of the first dust chamber 13, thereby reducing the blockage of the metal mesh of the coarse filter component 2 during the subsequent secondary filtration. At the same time, two connecting ports 121 are opened on both sides of the top of the dust cup, and a part of the dust is disturbed by the air and enters the left and right dust chambers, so that the dust particles are collected separately. The dust is collected and settled quickly, reducing the filtering load of the coarse filter component 2; in the second stage of filtration, the dust is blocked by the small holes of the metal mesh on the coarse filter component, and large particles of dust remain outside the coarse filter component 2; small particles of dust enter the coarse filter component 2, and the dust entering this cavity moves and collides inside, causing some dust to fall into the bottom dust cavity; in the third stage of filtration, other dust is driven upward by the air flow and is intercepted by the filter cotton or HEPA of the fine filter component 41, and the clean air flow enters the dust cup top cover 5 and is scented by the aromatherapy 52, and flows to other parts of the vacuum cleaner for clean air discharge.
