Specific embodiment
The technical solution in the embodiment of the present invention will be clearly and completely described below, it is clear that described implementation
Example is only part of the embodiment of the present invention, instead of all the embodiments.Based on the embodiments of the present invention, this field is common
Technical staff's all other embodiments obtained without creative efforts belong to the model that the present invention protects
It encloses.
The preferred embodiment that the invention will now be described in detail with reference to the accompanying drawings.
In order to reach the purpose of the present invention, the present embodiment provides a kind of two-stage dust and gas separated structure, as shown in Figure 1 and Figure 4,
Including a dirt cup 10, dirt cup 10 has an air inlet 101, and the level-one dust accumulation chamber connected with air inlet 101 is equipped in dirt cup 10
102, whirlwind cover 32 and interior dirt cup 33 in the level-one dust accumulation chamber 102 are further included, whirlwind cover 32 is looped around interior dirt cup 33
Peripheral side, the airflow channel 34 after level-one dust and gas detaches is formed between whirlwind cover 32 and interior dirt cup 33, is equipped in interior dirt cup 33
The two level dust accumulation room 331 connected with airflow channel 34, the interior buffering being equipped with for reducing air-flow rotating speed of the level-one dust accumulation chamber 102
Mechanism.
The present embodiment dust and gas first enters level-one dust accumulation intracavitary from air inlet, and a fraction is realized by the filtering of whirlwind cover
From the dust accretions after the separation of, level-one in level-one dust accumulation intracavitary, interior dirt cup is entered to along airflow channel by the dust and gas of whirlwind cover
Two level dust accumulation room in realize the second-order separation.
The present embodiment can play the role of hindering air-flow, drop by setting air-flow buffer mechanism in level-one dust accumulation intracavitary
It is low that level-one dust accumulation intracavitary air-flow rotating speed is stayed in after being detached by level-one, current rate is reduced, and then reduce level-one dust accumulation intracavitary
Dust enter in the second-order separation mechanism, reduce the burden of the second-order separation, promote level-one separative efficiency and level-one separating effect.
To advanced optimize the technique effect of the present invention, in other embodiment, on the basis of the above,
As depicted in figs. 1 and 2, the buffer gear is located at the bottom of the 10 level-one dust accumulation chamber 102 of dirt cup, and buffer gear is included along institute
State several gussets 31 of dirt cup 10 circumferentially.
Blocking and buffer gas flow can be played the role of using gusset in the present embodiment, and then reduce air-flow rotating speed, because
Dust after level-one detaches is the bottom of the level-one dust accumulation chamber of accumulation, by the bottom that gusset is arranged on to level-one dust accumulation chamber
Portion, rotating speed can not only be reduced, but also can directly accumulate under the blocking of gusset by being moved to the dust in level-one dust accumulation bottom of chamber portion
In level-one dust accumulation bottom of chamber portion, high degree avoids being deposited in the dust of bottom from ensureing level-one since distinguished and admirable effect is drifted about again
The stability of dust after separation, avoids dust from drifting to again in the second-order separation space.
To advanced optimize the technique effect of the present invention, in other embodiment, on the basis of the above,
As depicted in figs. 1 and 2, the height of several gussets 31 is accumulated from the corresponding position of the air inlet along the level-one
The circumferential direction of dirt chamber 102 gradually increases.
The present embodiment plays the role of hindering air-flow layer by layer by the variation of gusset height, can be to the dirt of different height
Gas is into row buffering.
