Blade 132 is arranged obliquely in the way of its upper surface is faced with air inflow direction.Blade 132 is from sucting 120
Separate configuration successively to the direction of dust bucket 133.In addition, blade 132 can be configured as, and when from sucting 120, air
The blade 132 that the upper surface of the blade 132 collided is not configured in tight front side is covered.That is, each blade 132 can be set
Into arranged in series, the lower end of the blade 132 positioned at rear side is higher than positioned at the upper end of the blade 132 of front side.In addition, the quilt of blade 132
Position before configuration to the upper inside walls for reaching the main body 110 that inertia dust collecting part 130 is configured.So, prevent air with
Blade 132 flows out between blade 132 without collision, the dust catching efficiency thus, it is possible to improve inertia dust collecting part 130.
A part (being shown in broken lines) included in the dust in the air for flowing into inertia dust collecting part 130 can not follow sky
The flowing (being shown with arrow) of gas and collided with blade 132.Blade 132 has the side of acute angle with its angle relative to inflow direction
Formula is tilted, therefore the particle collided with the blade 132 of front side is moved to the blade 132 of rear side and collided again.Pass through weight
Multiple this process, final dust enters inside dust bucket 133.On the other hand, the angle and interval that blade 132 is configured are not limited to
The situation of diagram, it may be considered that the size of the dust to be collected, weight, speed of flowing etc. and suitably select.
Dust bucket 133 is configured as entrance at the rear of last blade 132 towards air inflow direction.If air stream
Enter inside dust bucket 133, then lose inertia force comprising aerial dust and be deposited in inwall.In order to prevent the ash being captured
Dirt is flown upward again, preferably dust bucket 133 be formed its section have it is hook-shaped.
On the other hand, as shown in the figure or multiple inertia dust collecting parts 130 along the direction vertical with inflow direction side by side
Arrangement.Accordingly, dust is realized simultaneously in each inertia dust collecting part 130, thus, it is possible to increase dust catching efficiency.
In baffle-type inertia dust collecting part according to the second embodiment of the present invention, stream is formed to make air with zigzag
It is mobile, so as to carry out dust to dust.
Reference picture 3, inertia dust collecting part 230 includes multiple secondary filters 232, and secondary filter 232 includes mutually opposing two
Individual next door 233 and the blocking wall 234 that a side end in two next doors 233 is interconnected.Multiple secondary filters 232 by with
It is set to blocking wall 234 that to be opposed to unlimited opening portion mutually opposing.In addition, a next door 233 in two next doors 233 is inserted
Stream F is formed in the opening portion of another secondary filter 232.
The air for flowing into inertia dust collecting part 230 is advanced without the former flow direction of normal direction, but by blocking wall 234 opposed therewith
Stopped.Can be with blocking wall 234 to collide comprising aerial dust.Now, its flow direction of air is converted into phase
Opposite direction, and flow between the next door 233 of opposed two secondary filters 232.Afterwards, air can be inhaled into the secondary mistake in the side of portion 120
The blocking wall 234 of filter 232 stops again.In addition, can be again with blocking wall 234 to touch comprising aerial dust
Hit.As a result, its flow direction of air is converted into identical with initial inflow direction and flowed out to the outside of inertia dust collecting part 230.
So, air is during by inertia dust collecting part 230, and its flow direction is converted to opposite direction for several times,
During being somebody's turn to do, the relatively large dust of inertia force can not follow flowing and be collided with blocking wall 234, thus by inertia dust collecting part
230 trappings.Therefore, air by stream F move during, with block wall 234 collide the inter coagulation of dust phase and size become
Greatly, thus from block wall 234 fall down after because of gravity fall.
Due to the dust that inertia departs from flow circuits and is collided with blocking wall 234, drop and be caught from collecting plate 235
Collection, the dust for being deposited in collecting plate 235 is flown upward and prevents platform 236 from stopping, so as to will not again be flown upward due to flowing.
On the other hand, the section shape of above-mentioned inertia dust collecting part 230, orientation, secondary filter 232 number not
It is limited to the situation of diagram, can not only has circular section shape, there can also be the section shape of corner angle, not only can be with
