[0035] A first filter assembly 2, assembled in the first dust chamber 12;

[0036] The cover body 4 divides the inner cavity of the dust cup body 1 and the first dust cavity 12 into a plurality of independent dust collecting cavities. The dust cup body 1 is provided with a first air duct 13 connecting the first dust cavity 12 and the plurality of dust collecting cavities at the top of the cover body 4. The first air duct 13 is connected to the second air duct 16.

[0037] At least one third filter assembly 5 is assembled in the air guide cover and connected to the second air duct 16 and the dust cup air outlet 17 of the dust cup body 1 through the corresponding ventilation mesh opening 51.

[0038] like Figure 4-6 As shown, in this embodiment, the cross-sections of the air guide cover and the second air duct 16 are waist-shaped or elliptical, and the cross-sections of the air outlet of the second air duct 16 and the third filter component 5 are circular. Of course, other shapes such as polygons, irregular shapes, etc. can also be used. The air outlet of the second air duct 16 and the third filter component 5 can be designed in multiple ways to meet actual assembly requirements.

[0044] The working principle of a dust cup with an independent multi-cavity multi-stage filtering structure in this embodiment includes: Figure 3-6 As shown, the arrow indicates the direction of internal airflow when the dust cup is used for dust collection. When the dust cup is mounted on a mite remover or a vacuum cleaner for dust collection, in the first stage of filtration, the elastic air guide plate 111 of the dust cup air inlet 11 is designed to achieve the air inlet tangent point, ensuring that the air has a rotating effect when entering, so that the dust has centrifugal force, and the large dust particles settle to the bottom of the first dust cavity 12, reducing the filtration load and blockage on the metal mesh on the first filter component 2; in the second stage of filtration, the dust is blocked by the small holes of the metal mesh on the first filter component 2, and the large dust particles are trapped in the first dust cavity 12, and the small dust particles enter the metal mesh. The dust entering the inner cavity of the first filter component 2 moves and collides inside, causing some dust to fall into the dust collection cylinder for storing dust, and the airflow drives the fine dust particles to move upward Enter the first air duct 13; the third stage of filtration, the unfiltered fine dust rotates through the air inlet of the multi-cone filter outer sleeve 31 in the multi-cone structure of the second filter component 3 into the space formed by the multi-cone filter inner sleeve 32. Since it is a centrifugal structure, the dust is further dropped by centrifugal force, and the dust settles to the corresponding second dust cavity 14 or the third dust cavity 15 through the bottom dust falling port. The airflow enters the second air duct 16 through the multi-cone filter inner sleeve 32, so that the dust and airflow are further separated; the fourth stage of filtration, a part of the remaining dust is filtered and retained by the filter cotton or the third filter component 5 of HEPA, and the clean air passes through the ventilation mesh port 51 and is scented by the aromatherapy, continues to flow, and is discharged from the dust cup through the dust cup outlet 17.

[0045] In summary, due to the adoption of the above technical solution, the dust cup with an independent multi-cavity multi-stage filtering structure of this embodiment has the following beneficial effects compared with the prior art:

[0046] The dust cup uses a multi-stage filtration structure composed of metal mesh, multi-cone filtration structure and filter cotton or HEPA, and cooperates with multiple tightly arranged dust chambers isolated by the cover body to ensure the filtration efficiency of the product, reduce the value of dust dispersion at the outlet, further improve the mite removal effect, and achieve the effect of using the dust cup without loss of suction power. The dust cup structure is more compact and the space utilization rate is improved. The above structural design also allows dust and hair of different properties to be filtered at multiple levels, intercepted, dusted and collected separately, which can reduce the filtration load and blockage of each filter component.
