Specific embodiment
It is done referring to embodiment of the attached drawing to dust catcher and its working method in the present invention with multistage cyclone separated structure
It further illustrates.
As shown in the picture, the present embodiment is a kind of dust catcher with multistage cyclone separated structure, includes dirt cup 1, institute
It states dirt cup inner hollow and is formed with dirt chamber, deflector 2 is provided in dirt chamber, deflector is circumferentially fixed on the inner wall of dirt cup
And deflector is located at upper position, that is, upstream of entire dirt cup, and the dirt chamber is separated into level-one dirt chamber from the bottom to top by deflector
3 and second level dirt chamber 4, it is independent from each other between level-one dirt chamber and second level dirt chamber, level-one dirt chamber is for biggish in filtered airflow
Dust, rubbish.And second level dirt chamber is mainly used for storing filtered some little particle dust such as hairs etc..
It is provided with cyclone separator 5 in level-one dirt chamber, dirt cup bottom cover 6 is equipped in the bottom cover of the dirt cup, described
Air inlet 61 is offered on dirt cup bottom cover, air inlet is connected to cyclone separator, the air-flow with rubbish from the air inlet into
Enter into cyclone separator, the inside of cyclone separator is formed with air-inlet cavity, be provided with drainage plate in air-inlet cavity, drainage plate with
The gap formed inside air-inlet cavity is gradually reduced from the bottom to top, in this way, the air-flow for entering air-inlet cavity is just guided shape by drainage plate
It at whirlwind, is formed on the middle section side wall of cyclone separator and gets rid of grey mouth 51, the biggish rubbish of volume can be from getting rid of ash in air-flow
Mouth, which is thrown away, enters the first dirt chamber, and drainage plate is formed with opening on the side wall of the cyclone separator, the gas after forming whirlwind
Stream enters disengagement chamber by opening outflow air-inlet cavity.Pass through centrifugal force in disengagement chamber entrainment of the cyclonic air flow of a large amount of dusts
Effect so that air-flow is separated with part dust, dust falls into that level-one dirt is intracavitary from level-one dirt chamber ash port 7, and air-flow here is real
It has already passed through in matter and separates twice, i.e., bulky rubbish is directly thrown away from getting rid of grey mouth, this is first separation, remaining large volume
Dust falls into that level-one dirt is intracavitary, this is first separation again in disengagement chamber from level-one dirt chamber ash port, and on cyclone separator
Several mesh 52 are offered on the side wall in portion, and cone fluid course 8 is formed at the top of cyclone separator, is mingled with a small amount of dust
Air-flow enter the top of cyclone separator from the mesh and flow into the cone fluid course, the top of cyclone separator is
It is separated by drainage plate above-mentioned, specific air-flow trend is that the air-inlet cavity of cyclone separator, air inlet are first entered from air inlet
The top of chamber and cyclone separator is separated by drainage plate, and air-flow flows into disengagement chamber from the opening on drainage plate, is returned using mesh
The top of cyclone separator is flowed to, then from the cone fluid course outflow being located at the top of cyclone separator.
Deflector above-mentioned is covered on the top of cone fluid course, is circumferentially fixed with several second levels in the bottom of deflector
Rotation cone 9, offers on the deflector and revolves the cone consistent diversion trench 21 of quantity with the second level, each diversion trench is corresponding
One second level rotation cone, multiple second levels, which are revolved, to be fitted together between cone by a mounting disc 10, and the top opening of second level rotation cone is opened
