The specific embodiment

Referring to Fig. 1, air cleaner has a housing 1, the gas channel 3 that is provided with draught fan impeller 2 in the housing 1 and flows through for air.Draught fan impeller 2 drives rotation by blower motor by

belt pulley

4,5, and the rotating shaft 6 of draught fan impeller 2 is supported by housing and the gripper shoe 7 that is fixed in the housing.Be provided with the cylinder 8 of accumbency in gas channel 3, cylinder 8 one side end faces are uncovered, and the opposite side end face is provided with end plate 9, and the cylinder of cylinder 8 has mesh, and reticular density can be decided according to required filtered air foreign material size.The cylinder 8 and draught fan impeller 2 shared rotating shafts of present embodiment, draught fan impeller 2 are positioned at cylinder 8 opening ends and fixing with cylinder 8, make impeller 2 take into account the effect of back-up roller 8.This frame mode makes the supporting construction of cylinder 8 the simplest.Can certainly make the rotating shaft of the rotating shaft of cylinder 8 and draught fan impeller 2 independent separately, rotate by special motor-driven cylinder 8.Gas channel 3 forms the turning at cylinder 8 places, one side 3a at turning is facing to the opening end of cylinder 8, and another side 3b is facing to the cylinder of cylinder 8.

When utilizing the utility model filtered air, as shown in Figure 2, in housing 1, poured into adsorbing liquid 10 earlier.Liquid can pour into from the gas channel 3a or the 3b of housing.The kind of liquid is decided on the air foreign material of actual required absorption, for example can be clean water, also can be the soup of various effects such as have taste removal, deoil.After starting blower fan, draught fan impeller 2 and cylinder 8 rotate together, draught fan impeller 2 makes air enter gas channel, and at first enter in the cylinder 8, because the cylinder of cylinder 8 has mesh, so air is easy to pass cylinder 8 cylinders and from gas channel 3b outflow housing 1, still foreign material such as airborne oil smoke, grit but are difficult to pass the mesh of rotation at a high speed, so foreign material are brought in the liquid 10 by the cylinder of cylinder 8, air is purified; On the other hand, liquid 10 is stirred by cylinder 8 and forms the fine drop of a large amount of disperses, and the suction-operated of liquid further strengthens.In fact, the flow direction of air also can be to enter housing 1 from gas channel 3b, and through flowing out from gas channel 3a behind the cylinder of cylinder 8, the airflow direction of air can be by the decision that turns to of the helical angle of draught fan impeller 2 and blower fan again.

For the ease of in use constantly changing the liquid in the housing 1, also can be shown in and offer inlet 11 and liquid outlet 12 on the housing 1 as Fig. 3,4.The method of replacing liquid can have multiple, for example with circulating pump the liquid of cleaning is constantly imported in the housing 1 from inlet 11, and the liquid that constantly will pollute is discharged from liquid outlet 12 again, but this mode consumed power.Therefore as preferred forms, the liquid outlet 12 among Fig. 3,4 is higher than inlet 11, and liquid outlet 12 is higher than the liquid level that pours into liquid in the housing 1, and along the direction of rotation of cylinder 8, liquid outlet 12 is prior to inlet 11 from top to bottom.During use such as Fig. 5, shown in 6, with a container 13 carrying liquids 10, and in the inlet 11 immersion liquid 10 with housing, make liquid 10 pour into housing 1, part cylinder until cylinder 8 is immersed in the liquid 10, rotation along with cylinder 8, the liquid major part that is taken up by cylinder 8 is thrown on housing 1 inwall, and housing liquid outlet 12 is higher than liquid level and prior to inlet 11, therefore most liquid will be along the inner walls landing to liquid outlet 12, thereby make the liquid that has adsorbed foreign material constantly discharge housing 1, and the liquid 10 in the casing will be constantly from inlet 11 additional entering in the housing 1.With this respective outer side edges, preferably be shown in the casing 13 of contain fluid dividing plate 14 is set as Fig. 5,6, the position of dividing plate just makes the inlet 11 of housing and the both sides that liquid outlet 12 is positioned at dividing plate 14, and the bottom of housing 1 can just be withstood in the upper end of dividing plate 14, liquid in the casing 13 just can be divided into clean and contaminated two parts like this, and the liquid that can not that flows out from liquid outlet 12 flows back in the housing 1 again.As a kind of embodiment, the casing 13 of the utility model and contain fluid whole sale that can be assembled together.

As further improvement, as shown in Figure 1, be provided with the ring washer 15 that turns up respectively at end face place, the both sides of cylinder 8, on housing 1 inwall, be fixed with the annulus corresponding 16 with described ring washer, annulus 16 is axially close with ring washer 15.Close ring washer and annulus play sealing function, can prevent that cylinder that air does not pass cylinder 8 from just directly flowing through the gas channel 3 of housing.Annulus 16 in ring washer 15 on the cylinder 8 and the housing 1 can be provided with a plurality of, and is spaced, and can strengthen sealing effectiveness like this.

Because filter is using an end after the time, the adsorbed foreign material of liquid can be formed bulk, and the size of bulk foreign material can constantly increase, until mesh size greater than the cylinder cylinder, therefore just very difficultly after the bulk foreign material enter cylinder from the opening end of cylinder come out from cylinder again, cause the foreign material of accumulation in the cylinder more and more, finally have a strong impact on the performance of filter.Tackle cylinder is further improved for this reason.Referring to Fig. 7, Fig. 8, on the cylinder inwall of cylinder 8, be fixed with helical blade 17, the helical angle direction of helical blade is consistent with the helical angle direction of draught fan impeller 2, on this external cylinder 8, has for the through hole 18 that discharges foreign material in the position near the cylinder sealing end.For the clear structure of expressing helical blade, stereogram shown in Figure 8 has saved all structures beyond the helical blade 17.Along with the rotation of cylinder 8, helical blade 17 can constantly be driven the foreign material in the cylinder sealing end to cylinder, and the bulk foreign material are discharged from through hole 18.Through hole 18 both can have been opened in position shown in Figure 7, also can open on end plate 9.If the direction of rotation of draught fan impeller 2 is to make air enter, discharge from gas channel 3a from gas channel 3b, then the effect of helical blade 17 is that the foreign material in the cylinder 8 are driven out of from the opening end of cylinder, and can not offer through hole 18 this moment.

For the ease of removing the foreign material of deposition in the housing 1, also can on housing 1, offer through hole 19 as shown in Figure 7 for the discharging foreign material.

Diameter of cylinder of the present utility model can be decided according to the air mass flow of design.In addition, because cylinder rotates, even therefore do not pour into liquid in housing, the utility model also has certain filter effect.
