Abstract
The dust separating mechanism for vacuum cleaner includes front stage of cyclonic separating part, the back stage of cyclonic separating part, and the connecting passage between these two parts. The front stage of cyclonic chamber has top baffle with openings and the baffle extends downwards spirally from over the airflow entering passage of the preceding stage. Relatively heavy large dust grains after being sucked into the inside cavity of the front stage one cyclonic barrel will rotate downwards spirally to stay in the bottom of the back stage of the cyclonic barrel. In this way, the relatively heavy large dust grains are separated.
Description
Technical field
The present invention relates to a kind of dust separation apparatus of dust catcher,
Background technology
In the prior art, adopted two-stage dust cyclonic separation technology in the dust catcher of DYSON company, it comprises prime cyclonic separation part, back level cyclonic separation part, be used to be communicated with the interface channel of prime cyclonic separation part and back level cyclonic separation part, the prime cyclonic separation partly is used for bulky grain, heavier dust separates, thinner dust and air-flow are then through entering back level cyclonic separation part behind the interface channel, by back level cyclonic separation part tiny dust is separated, fine dust after the separation enters in the laying dust bucket, and clean air-flow is discharged in the atmosphere after fan blade through the negative pressure exit passageway.Described prime cyclonic separation partly comprises prime whirlwind bucket, be arranged at the prime air-flow admission passage of the top side wall portion of prime whirlwind bucket, be arranged at the laying dust bucket of the inner chamber central part of prime whirlwind bucket, when oarse-grained dust rotates with cyclonic air flow, bulky grain run into lose that inertia can drop to the below behind the inwall of prime whirlwind bucket and and flow separation.Described back level cyclonic separation partly comprises a plurality of backs level whirlwind bucket, each back level whirlwind bucket is positioned at the top of laying dust bucket, the bottom of each back level whirlwind bucket has back level whirlwind bucket bottom opening, back level whirlwind bucket bottom opening is arranged in the inner chamber of laying dust bucket, the top of back level whirlwind bucket is fixed with central tube, this central tube stretches into downwards in the inner chamber of back level whirlwind bucket, and the upper portion side wall of back level whirlwind bucket is provided with back level air-flow admission passage.After air-flow rotates, enter interface channel in the inner chamber of prime whirlwind bucket, enter a back level air-flow admission passage from interface channel again and enter again in the level whirlwind bucket of back through the perforate side direction of the inboard bucket of prime whirlwind bucket wall.Because rotate rear side in prime whirlwind bucket, the air-flow of band dust enters interface channel to inwardly (edge haply towards axis direction); and the rotary speed of air-flow in this prime whirlwind bucket is lower; therefore heavy particle dust that should be separated also can be inhaled in the interface channel owing to the effect of negative pressure, causes prime cyclonic separation part dust-separating deleterious.When air-flow tangentially after prime air-flow admission passage enters prime whirlwind barrel cavity, the flow direction of air-flow is dispersed, the air-flow that enter early stage can produce the air-flow that the later stage enters and disturb, and has influenced cyclone effect.
Summary of the invention
The object of the invention provides a kind of prime whirlwind bucket that makes and can separate heavier dust granule, the dust separation apparatus of the dust catcher of the interface channel of level and back level whirlwind bucket after a heavy dust can not enter.
Technical scheme of the present invention is: a kind of dust separation apparatus of dust catcher, comprise prime cyclonic separation part, back level cyclonic separation part, be used to be communicated with the interface channel of prime cyclonic separation part and back level cyclonic separation part, described prime cyclonic separation partly comprises prime whirlwind bucket, be arranged at the prime air-flow admission passage of the top side wall portion of prime whirlwind bucket, be arranged at the laying dust bucket of the inner chamber central part of prime whirlwind bucket; Described back level cyclonic separation partly comprises a plurality of backs level whirlwind bucket, each back level whirlwind bucket is positioned at the top of laying dust bucket, the bottom of each back level whirlwind bucket has back level whirlwind bucket bottom opening, back level whirlwind bucket bottom opening is arranged in the inner chamber of laying dust bucket, the top of back level whirlwind bucket is fixed with central tube, this central tube stretches into downwards in the inner chamber of back level whirlwind bucket, the upper portion side wall of back level whirlwind bucket is provided with back level air-flow admission passage, cavity between described prime whirlwind bucket and the laying dust bucket constitutes the prime cyclone chamber, the top of this prime cyclone chamber is provided with baffle plate, this baffle plate begins from the top of prime air-flow admission passage to extend spirally downwards around the laying dust bucket, have many perforates on the described baffle plate, be connected by midfeather between the baffle plate initiating terminal of described baffle plate and the baffle plate terminating end; Described prime cyclone chamber is connected with interface channel by perforate.
The present invention compared with prior art has following advantage:
Because the effect of gravity and helical baffle; make air-flow after prime air-flow admission passage enters the prime cyclone chamber; the diversity of air-flow is little; effective under the screw; midfeather can stop air-flow to enter communication passage from baffle plate initiating terminal to the gap between the baffle plate terminating end; therefore heavier bulky grain dust in the inner chamber that is inhaled into prime whirlwind bucket after; can be rotated down by spiral; and air stream outlet is positioned at the tapping of the baffle plate at top; therefore the heavier dust of particle is difficult for overcoming the effect of gravity and moves up; heavier particle dust can be stayed the bottom in the level whirlwind bucket of back, so prime cyclonic separation part can play the effect that big heavier particle dust is separated.
