Abstract

A dust bin and a vacuum cleaner combination provided with the dust bin are provided. The dust bin includes a dust chamber, a dust inlet detachably connected to a dust suction apparatus, and a sealing structure for implementing the sealing between the dust suction apparatus and the dust bin. The dust suction apparatus has a dust outlet joined to the dust inlet. The vacuum cleaner combination includes a dust suction apparatus and a dust bin detachably connected to the dust suction apparatus. The dust suction apparatus has a housing and a dust cup assembly connected to the housing. The dust cup assembly includes a cup body and a filter apparatus disposed in the cup body. Compared with the prior art, in the present invention, a detachable multi-purpose dust bin with a simple structure is disposed, so that the dust collection chamber of the vacuum cleaner is flexibly increased.

First claim

What is claimed is:

1. A vacuum cleaner combination, comprising:
a dust suction apparatus, the dust suction apparatus having a housing; and
a dust cup assembly connected to the housing, and the dust cup assembly comprising:
a dust suction inlet for guiding an external air flow into the dust suction apparatus;
a cup body;
a filter apparatus disposed in the cup body;
a dust outlet disposed on the cup body; and
a dust cup cover for sealing the dust outlet,

wherein the vacuum cleaner combination further comprises a dust bin that is configured to be joined to the dust suction apparatus, the dust bin comprising a dust chamber and a dust inlet in communication with the dust chamber, and the cup body being joined to the dust inlet,
wherein the vacuum cleaner combination is configured to convert between a first working mode and a second working mode;
wherein, in the first working mode, the dust suction apparatus is separated from the dust bin, the filter apparatus of the dust cup assembly filters dust suctioned from the dust suction inlet, and the cup body collects the suctioned dust; and
wherein, in the second working mode, the dust suction apparatus is joined to the dust bin, the dust outlet is in communication with the dust inlet, the filter apparatus of the dust cup assembly filters dust suctioned from the dust suction inlet, and the dust bin collects the suctioned dust through the dust outlet and the dust inlet.

2. The vacuum cleaner combination according to claim 1 , wherein the dust outlet is airtightly joined to the dust inlet.

3. The vacuum cleaner combination according to claim 2 , wherein a first sealing member is disposed between the dust outlet and the dust inlet.

4. The vacuum cleaner combination according to claim 3 , wherein the dust cup assembly has a second sealing member that implements mutual sealing between the dust outlet and the dust cup cover, and the first sealing member circumferentially surrounds the second sealing member and the dust cup cover.

5. The vacuum cleaner combination according to claim 4 , wherein the dust bin has an abutting portion for controlling the dust cup cover to open.

6. The vacuum cleaner combination according to claim 1 , wherein the vacuum cleaner combination comprises a float member disposed in the dust bin and a joint member and a control element that are disposed on the dust suction apparatus, and the float member is floatingly disposed in the dust chamber; the joint member and the float member constitute a switch assembly, and the switch assembly is configured to generate a trigger signal when the float member reaches a preset level; and the control element performs a corresponding action according to the trigger signal.

7. The vacuum cleaner combination according to claim 6 , wherein one of the float member and the joint member in the switch assembly is a sensing member, and the other of the float member and the joint member is a sensed member; and when the float member reaches the preset level, the sensing member senses the sensed member to generate the trigger signal.

8. The vacuum cleaner combination according to claim 6 , wherein the dust bin comprises a limiting portion, and
wherein the float member is joined to the limiting portion and is movable relative to the limiting portion.

9. The vacuum cleaner combination according to claim 6 , wherein the dust suction apparatus has a control element, and according to the trigger signal, the control element sends an alarm signal and/or controls the driving member to stop driving.

10. The vacuum cleaner combination according to claim 1 , wherein the vacuum cleaner combination comprises a float member disposed in the dust bin, a switch assembly, and a control element disposed on the dust suction apparatus, the float member is floatingly disposed in the dust chamber, the switch assembly is configured to generate a trigger signal when the float member reaches a preset level, and the control element performs a corresponding action according to the trigger signal.

11. The vacuum cleaner combination according to claim 1 , wherein the dust suction apparatus has a first dust collection capacity, the dust bin has a second dust collection capacity, and a dust collection capacity of the vacuum cleaner combination is the sum of the first dust collection capacity and the second dust collection capacity.

12. A stick vacuum cleaner, comprising a hollow extension pipe and a cleaner head, wherein the stick vacuum cleaner further comprises the vacuum cleaner combination according to claim 1 , the dust suction apparatus in the vacuum cleaner combination is detachably connected to the extension pipe, one end of the extension pipe is in communication with the dust suction inlet of the dust suction apparatus, the other end of the extension pipe is in communication with the cleaner head, and the cleaner head is provided with a suction passage in communication with the inside of the extension pipe.
