Hereinafter, the operation of the filter means of the present invention will be described in detail.

First, as shown in FIG. 2, the operator applies power to the main body 300 by using the power plug 350 of the cord reel device 420 and the dust of the cleaning part using the suction device 100. And clean the foreign objects.

That is, when the dust and foreign matters of the cleaning part are sucked into the suction device 100 by the strong suction force of the motor 430 shown in FIG. 2 together with the external air, the dust is introduced into the main body 300 through the communication device 200. The dust bag 410 is collected in the dust collecting chamber 370 is collected.

At this time, the odor generated in the dust collecting chamber 360 when collecting the dust and foreign matter to the dust bag 410 is removed by the first filter 440 installed in the partition panel 360, as well as the motor when driving the cleaner A portion of the carbon (carbon) powder generated at 430 and its smell are removed by the second filter 450.

In addition, the carbon (carbon) powder and some of the odor and the odor of the motor 430 discharged through the exhaust grill 460 but not completely removed by the second filter 450 are removed while passing through the filter means 500. Will be.

That is, some carbon (carbon) powder and its odor that are not completely removed by the second filter 450 are discharged to the air outlet 461 of the exhaust grill 460 by the exhaust wind of the motor 430. Carbon (carbon) powder and its odor discharged to the air outlet 461 are introduced into the air inlet 513 formed in the front plate 511 of the air collecting container 510 and collected in the air collecting container 510. Will be.

In addition, the carbon (carbon) powder and its odor collected in the air collecting container 510 revolves inside the air collecting container 510 together with the exhaust wind and is discharged through the connection hole 517. Carbon (carbon) powder and odor discharged through the 517 is introduced into the connecting pipe 520 through the through hole 622 of the second coupling member 620.

At this time, when the exhaust wind flows into the connecting pipe 520, the valve bearing 700 which is installed inside the first connecting pipe 521 of the connecting pipe 520 to seal the through hole 622 is also shown. As shown in FIG. 7, the cloud is moved in the direction of the locking step 521a by the pressure of the exhaust wind, and at the same time, the through hole 622 is opened, and the carbon (carbon) powder discharged through the connection hole 517 and Odor is introduced into the first connecting pipe 521 and the second connecting pipe 525.

That is, when the through-hole 622 is opened while the valve bearing 700 moves in the direction of the locking step 521a by the pressure of the exhaust wind, the first connection pipe 521 through the through-hole 622. Carbon powder and odor introduced into the interior of the valve are moved to the second connecting pipe 525 through the gap between the bearing 700 and the first connecting pipe 521 and the gap between the locking jaw (521a).

In addition, carbon (carbon) powder and odor introduced into the second connection pipe 525 are introduced into the connection pipe coupling cylinder 530 through the micro holes 525a, and the connection pipe coupling cylinder 530 is provided. The first through hole 533 and the second through hole 541 of the filter cylinder 540 is introduced into the filter cylinder 540.

On the other hand, the pressure of the exhaust wind flows from the connecting pipe 520 to the connecting pipe coupling cylinder 530 is primarily reduced by the sponge 800 installed in the connecting pipe coupling cylinder 530 filter ( 540).

In addition, the exhaust wind and carbon (carbon) powder and the odor introduced into the filter cylinder 540 is moved through the exhaust wind air passage 545 is discharged to the outside through the exhaust port 543, wherein the exhaust The wind pressure is discharged to the outside through the exhaust port 543 in a state where the wind pressure is completely reduced secondarily by the curved surfaces of the first exhaust wind guide member 547 and the second exhaust wind guide member 549. The (carbon) powder and its odor are discharged to the outside through the exhaust port 543 in a completely filtered state by the water 900 contained in the lower part of the exhaust wind air passage 545.

Therefore, carbon (carbon) powder and its odor discharged to the outside of the main body 300 through the exhaust grill 460 during vacuum cleaning are completely filtered by the filter means 500 coupled to the rear surface of the exhaust grill 460. In this state, only the exhaust wind is discharged, thereby preventing harm to the human body, and exhaust noise caused by the exhaust wind is reduced.

As described above, according to the present invention, the filter means using water is coupled to be firmly fixed to the rear surface of the exhaust grill, and carbon (carbon) powder and its odor discharged to the outside of the main body through the exhaust grill during vacuum cleaning are exhausted. Since only the exhaust wind is discharged in a completely filtered state by the filter means coupled to the rear surface of the grill, it is possible to prevent harm to the human body and to reduce the exhaust noise by the exhaust wind.
