As shown in
As shown in
The dust baffle 40 is disposed between an outer wall 202 of the cyclone barrel 20 and an inner wall 102 of the dust-collection container 10 to shield the dust depositing area, so that the dust is prevented from depositing in the dust depositing area A.
With disposing the dust baffle 40 between the outer wall 202 of the cyclone barrel 20 and the inner wall 102 of the dust-collection container 10, the dust depositing area A is shielded and separated from the dust in the dust-laden air collected in the dust-collection container. Thus, the dust cannot enter into and be deposited in the dust depositing area, so that the dust collector is easy to clean.
In some embodiments, the dust baffle 40 may be only connected with the inner wall 102 of the dust-collection container 10 and contacted with the outer wall 202 of the cyclone barrel 20. Thus simplifying the structure and assembling process of the cyclone barrel 20.
Alternately, the dust baffle 40 may be only connected with the outer wall 202 of the cyclone barrel 20 and contacted with the inner wall 102 of the dust-collection container 10.
As shown in
Alternately, as shown in
In addition, the dust baffle 40 may be an arc plate. An upper end and a lower end of the arc plate are bent toward the dust-laden air tube 30. Alternately, the dust depositing area A is formed as an area closed by the dust baffle 40, the cyclone barrel 20 and dust-laden air tube 30, Thus the dust is prevented from entering the dust depositing area A to the maximal extent.
In some embodiments, as shown in
The cyclone barrel 20 is disposed in the second chamber 104 and separates the dust from the dust-laden air. The cyclone barrel 20 has an air inlet 201 communicated with the dust-laden air inlet 101 via a dust-laden air tube 40, such that the clean air separated from dust by the filter 30 can pass through the second chamber 104 and the first chamber 103 in turns, and finally be discharged from the dust-collection container 10. Moreover, the air inlet 201 may be formed in a side wall of the cyclone barrel 20 and the barrel 20 has an open upper end 202 and a closed lower end 203.
In some embodiments, a lower end of the filter cup 32 is extended into the cyclone barrel 20 through the open upper end 202 of the cyclone barrel 20, and the open upper end 202 of cyclone barrel 20 is spaced apart from a lower surface 511 of the flange 51, in other words, an annular gap D is form between the upper end 201 of the cyclone barrel 20 and a lower surface 511 of the flange 51.
The rubbish, such as facial tissue, can pass through the gap D between the upper end 201 of the cyclone barrel and the lower surface 511 of the flange 51 and be collected in the dust-collection container 10, so that the cyclone barrel 20 cannot be blocked and the reliability of the dust collector is improved. Furthermore, the gap D also improves the separating performance of the dust collector.
A distance between the lower surface 511 of the flange 51 and the upper end 202 of the cyclone barrel 20 ranges from 10 mm to 35 mm, namely a height of the gap D ranges from 10 mm to 35 mm, thus improving the duct collecting performance of the dust collector. In addition, an assemble process of the dust collector is simplified and an assembling efficiency of the dust collector is improved.
In some embodiments, as shown in
An air deflector is disposed in an upper part of the inner chamber, guides the air downward the lower part of the dust-collation container 10. In other words, the air deflector is disposed on the body 11 or the cover 12.
As shown in
Alternately, the air deflector is disposed an inner wall of the body 11. Thus, the air is guided toward the lower part of the dust-collection container 10, thus improving the dust collection efficiency.
The air deflector is spaced apart from the inner wall of the body 11 and disposed at a side away from the dust baffle 40, thus further improving guiding effect of the air in the dust-collection container 10.
As shown in
In some embodiments, the cyclone barrel 20 may be mounted onto the body 11 via screws. Therefore, it is easy to assemble and disassemble the dust-collection container 10 and the cyclone barrel 20, which not only improves the assembling efficiency of the dust collector, but also facilitates maintenance of the dust collector, thus reducing the maintenance cost.
In addition, the cyclone barrel 20 and the body 11 may be formed integrally. Therefore, the dust collector is easy to be manufactured and assembled, which not only improves the sealing effect of the dust collector, but also reduces the manufacturing cost of the dust collector.
As shown in
In some embodiments, a plurality of ribs 13 are arranged in a circumferential direction of the dust-collection container 10.
The plurality of ribs 13 such as four ribs are disposed at a lower part of the side wall of the dust-collection container 10, and arranged in a circumferential direction of the dust-collection container 10. An end of the rib 13 is connected with the side wall of the dust-collection container 10, and the other end of the rib 13 is extended inward in the dust-collection container 10. In other words, the ribs 13 are connected with the side wall of the dust-collection container 10, and extended toward a central axis of the dust-collection container 10.
Alternately, the rib 13 is connected with the side wall of the dust-collection container 10 and is perpendicular to the inner side wall of the dust-collection container 10. Therefore, the rib is disposed in the dust-collection container 10 and blocks the air circulated in the dust collector, thus facilitating accumulating of the dust at the lower end of the dust-collection container 10 quickly, thus improving the dust collection efficiency of the dust collector.
In addition, as shown in
A cleaner according to embodiments of the present disclosure includes the dust collector as described in the above embodiments of the present disclosure.
With the dust collector of the embodiments of the present disclosure, by disposing the dust baffle between an outer wall of the cyclone barrel and an inner wall of the dust-collection container, the dust depositing area is covered up and separated from the dust collected in the dust-collection container. Thus, the dust cannot enter into and be deposited in the dust depositing area, and the dust collector is convenient to clean and the service life of the cleaner is increased.
