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.
