Description
Technical field
The utility model relates to cleaner field, in particular to a kind of dust catcher dust barrel with reduction of speed structure and
Dust catcher.
Background technique
In the dust catcher used in current, the principle of diffusion type rotoclone collector is that dust enters and realizes dust in dirt cup
When separation, the dust of larger particles is whirlpooled down into the outer dust barrel of dirt cup, and the lesser dust of particle enters second level by aperture and revolves
Wind system enters interior dust barrel in the second level air inlet by top and finally whirlpools down to interior dust barrel bottom, this is to answer extensively now
A kind of structure, this structure effectively realize the separation of dust size particles, solve dust catcher and inhale during dust suction
The problem of power is easily lost.
But there is also some drawbacks for above-mentioned structure, can make complete machine if second level cyclone system reduction of speed is too fast
The performance (air date) of air data has biggish loss, and the suction ash in second level storage ash bucket is arbitrarily caused if reduction of speed is too slow
" fugitive dust " phenomenon is generated, and then block filter to influence the suction of its complete machine.

Specific embodiment
Exemplary embodiments of the present disclosure are described in more detail below with reference to accompanying drawings.Although showing the disclosure in attached drawing
Exemplary embodiment, it being understood, however, that may be realized in various forms the disclosure without should be by embodiments set forth here
It is limited.On the contrary, these embodiments are provided to facilitate a more thoroughly understanding of the present invention, and can be by the scope of the present disclosure
It is fully disclosed to those skilled in the art.
Dust catcher dust barrel embodiment with reduction of speed structure:
Referring to Fig. 1 to Fig. 2, a kind of dust catcher with reduction of speed structure provided by the embodiment of the utility model is shown in figure
Dust barrel comprising dust barrel 1, dust barrel 1 are equipped with an outer barrel 2 outside, i.e. dust barrel 1 is used as second level storage ash bucket, are arranged in outer barrel 2
There is the first air inlet 21, the second air inlet 11 is provided in dust barrel 1, dust barrel 1 has upper dust barrel portion 12 and lower dust barrel portion 13, upper dirt
The cross-sectional area of bucket portion 12 is greater than the cross-sectional area in lower dust barrel portion 13, is provided between upper dust barrel portion 12 and lower dust barrel portion 13
Closing in portion 14 is provided with the convex ribs 15 of multiple circumferentially equidistant distributions along closing in portion 14, convex ribs 15 on the inner wall in closing in portion 14
It is oval with the joint face 151 of the inner wall in closing in portion 14, and convex ribs 15 have curved surfaces 152, the length direction of convex ribs 15
