The sub-cover 6 can cover the bottom cover hole 31 and the area of ​​the primary dust collection chamber 4 near the outer wall of the secondary dust collection chamber 5. The rotating component 7 has a rocker arm 8 on the side opposite to the sub-cover 6. A pair of magnets 91 and magnetic metal 92 are provided between the other end of the bottom cover 3 and the other end of the sub-cover 6.

[0025] The aforementioned magnetic metal 92 is disposed on the bottom cover 3, and the magnet 91 is disposed on the sub-cover 6.

[0026] A rubber pad 10 is provided on the surface of the sub-cover 6 facing the secondary dust collection chamber 5, which improves the sealing performance of the primary dust collection chamber 4 and the secondary dust collection chamber 5.

[0027] A sealing ring 11 is provided between the bottom cover 3 and the inner wall of the dust cup 2.

[0028] The surface of the cover 6 opposite to the secondary dust collection chamber 5 described above has several spaced ribs 14, which reduces weight while improving the structural strength of the cover.

[0029] The aforementioned ribs 14, spaced apart, are distributed in a crisscross pattern.

[0030] Example 2: A dust cup for a vacuum cleaner includes: a multi-cone body 1, a dust cup 2, and a bottom cover 3 located below the dust cup 2. The dust cup 2 includes a secondary dust collection chamber 5 located within a primary dust collection chamber 4. The bottom of the dust cup 2 is provided with a bottom cover 3 for opening or covering the primary dust collection chamber 4.

[0031] The bottom cover 3 has a bottom cover hole 31 in its central area. One end of the bottom cover 3 has a rotating shaft 12. A sub-cover 6, which is used to open or cover the bottom cover hole 31, has a rotating component 7 with a rotating hole 71 at one end.

[0036] The aforementioned rocker arm 8 is located within the inner groove 13.

[0037] Working principle: After vacuuming, the dust in the dust collection chamber needs to be cleaned. By pressing the rocker arm 8, the sub-cover 6 rotates around the rotating shaft 12. When the magnet 91 and magnetic metal 92 between the other end of the bottom cover 3 and the other end of the sub-cover 6 disengage, the sub-cover 6 can remain open without external force. At this time, the bottom cover is always in a sealed connection with the dust cup. Since the opening of the bottom cover hole is larger than the opening of the secondary dust collection chamber, and the diameter of the sub-cover 6 is larger than the diameter of the secondary dust collection chamber, the dust in the primary dust collection chamber and the secondary dust collection chamber can be emptied simultaneously. After emptying the dust, the sub-cover 6 and the bottom cover 3 can be closed by slightly moving the sub-cover or by gravity.

[0038] The dust cup of the vacuum cleaner described above is always sealed between the bottom cover and the dust cup. It can simultaneously discharge the dust in the primary dust collection chamber 4 and the secondary dust collection chamber 5 through the bottom cover hole 31. This avoids the dust cup's sealing performance from repeated opening over a long period of time and improves the reliability of the handheld vacuum cleaner.

[0039] Furthermore, one end of the bottom cover 3 has a rotating shaft 12, and one end of the sub-cover 6, which is used to open or cover the bottom cover hole 31, has a rotating member 7 with a rotating hole 71. The rotating shaft 12 of the bottom cover 3 is embedded in the rotating hole 71 of the rotating member 7 of the sub-cover 6. The rotating member 7 has a rocker arm 8 on the side opposite to the sub-cover 6. A pair of magnets 91 and magnetic metal 92 are provided between the other end of the bottom cover 3 and the other end of the sub-cover 6. After the sub-cover is opened, it can maintain the open state without the aid of external force. When closed, it can automatically close under gravity or slight tugs, which improves the consumer experience and extends the service life without fatigue.
