Abstract

A dust collection container, capable of being installed in a vacuum cleaner, includes a case body and a blocking member. The blocking member is disposed in the case body to separate the case body into a dust chamber and a diversion chamber, a suction inlet corresponding to the dust chamber and an exhaust opening corresponding to the diversion chamber are disposed in the case body, and a barrier piece is disposed at the blocking member opposite to the suction inlet, so as to form a slow flow area between the barrier piece and the suction inlet to effectively disperse dirt.

Claims

1. A dust collection container, capable of being installed in a vacuum cleaner, comprising a case body and a blocking member, wherein the blocking member is disposed in the case body to separate the case body into a dust chamber and a diversion chamber, a suction inlet corresponding to the dust chamber and an exhaust opening corresponding to the diversion chamber are disposed in the case body, the blocking member further comprises a frame and a filter screen disposed on the frame, a barrier piece is disposed on the filter screen corresponding to the suction inlet, the barrier piece and the filter screen are two individual parts, and a length of the barrier piece is smaller than a length of the filter screen.

2. The dust collection container according to claim 1, wherein the case body further comprises a shell body and a lid body.

3. The dust collection container according to claim 1, wherein the barrier piece further comprises a plurality of hook portions, so as to enable the barrier piece to be disassembled and separated from the blocking member.

4. The dust collection container according to claim 1, wherein the suction inlet further comprises a sealing member.

5. A vacuum cleaner, comprising:

a dust collection container, comprising a case body and a blocking member, wherein the blocking member is disposed in the case body to separate the case body into a dust chamber and a diversion chamber, a suction inlet corresponding to the dust chamber and an exhaust opening corresponding to the diversion chamber are disposed in the case body, the blocking member further comprises a frame and a filter screen disposed on the frame, a barrier piece is disposed on the filter screen corresponding to the suction inlet, the barrier piece and the filter screen are two individual parts, and a length of the barrier piece is smaller than a length of the filter screen; and

an air-extracting device, having an air-extracting chamber and a power element, wherein the air-extracting chamber is disposed with an air-extracting opening corresponding to the exhaust opening and a gas outlet corresponding to an outside part of the vacuum cleaner, the power element is disposed in the air-extracting chamber, and enables a gas to be sucked from the suction inlet and exhausted from the gas outlet during operation.

6. The vacuum cleaner according to claim 5, wherein the case body further comprises a shell body and a lid body.

7. The vacuum cleaner according to claim 5, wherein the barrier piece further comprises a plurality of hook portions, so as to enable the barrier piece to be disassembled and separated from the blocking member.

8. The vacuum cleaner according to claim 5, further comprising a plurality of wheels, disposed at a bottom of the shell body.
