Embodiment 1

[0063] to combine Figure 1-Figure 11 As shown, the dust collection device provided in this embodiment includes:

[0064] dust cup 10;

[0065] The dust cup sewage outlet 14 is at least partly set through the dust cup 10;

[0066] The dust cup bottom cover 30 is opened and closed on the dust cup 10. The dust cup bottom cover 30 includes the first position state of blocking the dust cup sewage outlet 14, and the opening of the dust cup sewage outlet 14. the second location status; and

[0067] The sealing ring 20 is adapted to seal the interface between the dust cup bottom cover 30 and the dust cup drain port 14 through at least two layers of sealing parts.

[0068] The dust collecting device provided in this embodiment realizes the sealing of the interface between the dust cup bottom cover 30 and the dust cup sewage outlet 14 by setting the sealing ring 20, and the sealing ring 20 is sealed by at least two layers of sealing parts, thereby improving the sealing effect. As a...

Embodiment 2

[0103] On the basis of the dust collection device provided in the first embodiment above, the number of dust collection chambers of the dust collection device can also be increased by adding a secondary dust collection unit, and while increasing the number of dust collection chambers, multiple dust collection chambers The sealing of the dust collector is also an important problem to be solved in this plan. The following takes the two-stage dust collection device as an example to describe in detail.

[0104] combine Figure 12-Figure 17 As shown, the multi-stage dust collection device provided in this embodiment includes:

[0105] dust cup 10;

[0106] The secondary dust collection unit 40 is at least partially nested inside the dust cup 10;

[0107] The dust cup sewage discharge port 14 and the secondary sewage discharge port 42 are respectively formed through the dust cup 10 and the secondary dust collection unit 40 in the same direction;

[0108] The bottom cover 30 of th...

Embodiment 3

[0135] This embodiment provides a vacuum cleaner, including: a vacuum cleaner body, and

[0136] The dust collection device and / or the multi-stage dust collection device as described above.

[0137] Preferably, the vacuum cleaner is also provided with a host machine 90, and the interior of the host machine 90 is suitable for placing a negative pressure vacuum motor.

Abstract

The invention relates to the technical field of dust collectors, in particular to a multi-stage dust collecting device and a dust collector. The multi-stage dust collecting device comprises a dust cup; a secondary dust collection unit at least partially embedded in the dust cup; a dust cup drain outlet and a secondary drain outlet respectively formed by penetrating the dust cup and the secondary dust collection unit towards the same direction; a dust cup bottom cover arranged on the dust cup in an opening and closing manner, wherein the dust cup bottom cover has a first position state of simultaneously blocking the dust cup drain outlet and the secondary drain outlet and a second position state of simultaneously opening the dust cup drain outlet and the secondary drain outlet; and a sealing assembly suitable for sealing the joint of the dust cup bottom cover and the dust cup drain outlet through at least two layers of sealing parts and sealing the joint of the dust cup bottom cover and the secondary drain outlet through at least two layers of sealing parts when the dust cup bottom cover is in the first position state. The product plays a role in sealing at the same time, and it is guaranteed that the spaces of the two dust collecting cavities are separated and blocked from the outside.

Description

technical field [0001] The invention relates to the technical field of vacuum cleaners, in particular to a multi-stage dust collecting device and a vacuum cleaner. Background technique [0002] Vacuum cleaners are often provided with a dust cup for containing dust. The dust cup is provided with an interface position connected to the vacuum generating device and an interface position connected to the suction port. When the vacuum cleaner is working, the dust cup needs to be sealed to ensure Ensure that the negative pressure generated by the vacuum generating device is not lost, thereby ensuring that the suction of the vacuum cleaner is not lost. If the dust in the dust cup is to be discharged, it is necessary to reserve an opening for the discharge of dust, and when no sewage is required, the sewage outlet needs to be closed and well sealed; especially for vacuum cleaners with multi-stage separation devices, It often has multi-stage dust collection chambers, and the dust col...
