Description
Technical field
The utility model relates to a kind of parts of vacuum cleaner, is specifically related to a kind of dust-separating appliance of vacuum cleaner, especially a kind of Cyclonic separating apparatus.
Background technology
In vacuum cleaner, in order effectively dust to be separated from air-flow, various forms of cyclone separators are used in beginning widely.For example, PCT patent application WO98/35602 discloses the device on a kind of Cyclonic vacuum duster, the air intake that has dust tangentially is arranged at the top of cyclone chamber, center of top is air stream outlet (negative pressure source), air-flow rotates under centrifugal action after tangentially entering in the cyclone chamber, under the part dust to sedimentation separation, air-flow moves upward from central authorities simultaneously, discharges from the air stream outlet at top through filter.Though said structure can be realized dust separation to a certain degree, the dust that settles down is driven and enters once more in the ascending air by air-flow easily, causes the dust content in the ascending air big thus, and filter easily stops up, and needs often to clean.
For addressing the above problem, secondary separation device has appearred, promptly second level cyclone separator is set again at the air stream outlet rear of above-mentioned cyclone separator, simultaneously, increase the aperture of filter, tiny dust can pass through filter, to alleviate the stopping state of filter.Yet because the setting of secondary cyclone separator has caused the stream pressure loss to increase, efficiency of dust collection reduces.
Chinese invention patent application CN1899188A discloses a kind of secondary cyclone dust separating cup of vacuum cleaner, outer cylinder body perisporium at separator has the separator air inlet that is lower than dirt cup air inlet, the outer cylinder body center is provided with the inner barrel of coaxial arrangement, on inner barrel top, separator air inlet top offers with perisporium is tangent and rotates the air inlet of uniform arrangement by annular array, and the inner barrel inwall also is equipped with up big and down small divergent-cone wall.This structure is owing to be arranged on the secondary cyclone separator at the center of one-level whirlwind, the air inlet of offering annular distribution on the outer cylinder body links to each other with the one-level whirlwind, and on inner barrel, offer the air inlet that annular array rotates uniform arrangement, make that the stream pressure loss is little, but owing on outer cylinder body, offered the air inlet of annular distribution, make the effect of outermost one-level whirlwind greatly reduce, a large amount of dusts have entered the secondary cyclone, fail to play should producing effect of secondary cyclone separation.
Summary of the invention
The utility model purpose provides the vacuum cleaner secondary cyclone formula separator that a kind of stream pressure loss is little, efficiency of dust collection is high.
For achieving the above object, the technical solution adopted in the utility model is: a kind of vacuum cleaner secondary cyclone formula separator, comprise upstream cyclone body, downstream cyclone body and dust storage chamber, described downstream cyclone body is positioned at the inside of upstream cyclone body, be provided with the isolation ward of annular between described upstream cyclone body and the downstream cyclone body, air inlet one side of upstream cyclone body is provided with baffle plate, constitute the circular passage of extending thus to opposite side, between described circular passage far-end and the isolation ward, be provided with the filter opening array, the below, circular passage is outer dust storage chamber; Between described isolation ward and the downstream cyclone body, be provided with at least 3 tangential inlets, downstream cyclone body central authorities are cylinder, cylinder top is provided with the coniform grid that the tip makes progress, top one side of downstream cyclone body is provided with out the dirt breach, go out the dirt breach outside for going out the dirt passage, its below is secondary dust storage chamber, and coniform grid lower bottom part is provided with the gas outlet.
In the technique scheme, described tangential inlet is a unenclosed construction, and promptly the sidewall length of tangential inlet is not more than the diameter of inlet.
Described tangential inlet evenly distributes around the downstream cyclone body, and tangential inlet is positioned at the bottom of the downstream cyclone body on the secondary dust storage chamber.
Further technical scheme between described circular passage and the outer dust storage chamber, is provided with the cage that stretches the frustum that constitutes from the outside downside of inwall, is the control of dust passage between cage and the outer wall.
In the technique scheme, described air inlet is positioned at the top of upstream cyclone body.
Operation principle of the present utility model is: the air-flow that has dust enters the upstream cyclone body from air inlet, be subjected to the resistance shelves of baffle plate, under the effect of negative pressure source, dust storage chamber top is for the helical movement outside along the circular passage simultaneously, because eddy current effect, bulky grain ash fall enters the outer dust storage chamber of bottom, along with the attraction of negative pressure source, air-flow enters isolation ward through the filter opening array, in this process, the filter opening array plays a role in filtering, and the dust of larger particles all is blocked and sedimentation enters outer dust storage chamber; After the air-flow that has a small amount of thin ash enters isolation ward, enter from the tangential inlet of downstream cyclone body, obtain rotary power once more, in the cyclone body of downstream, air-flow moves upward as efficient cyclone around cylinder, and dust ash discharge breach from the upper end under action of centrifugal force throws away, enter secondary dust storage chamber through going out the dirt passage, clean air-flow descends from cone shape grid, is flowed out by the gas outlet, and the preceding filter of process motor enters motor.
Because the utilization of technique scheme, the advantage that the utility model compared with prior art has is:
1. the utility model is provided with the isolation ward of annular between upstream cyclone body and downstream cyclone body, end is provided with the filter opening array in the circular passage of upstream cyclone body, thereby, when primary dust removing, except rotatablely moving, utilization realizes the ash fall, also utilize the filter opening array further to filter the bulky grain dust, improved the efficient of primary dust removing;
2. in the cyclone body of downstream, central authorities are provided with cylinder, and the top is provided with inverted taper grid, makes air-flow rotate from bottom to top, and dust is easier in centrifugal action is thrown out of, and reaches the effect of efficient separation;
3. the downstream cyclone body is provided with the tangential inlet of a plurality of distributions, simultaneously, tangential inlet is an open type, thereby air-flow has on a small quantity through tangential inlet the time can be back to isolation ward, and the air that drives in the isolation ward rotates, thus, the air-flow that has thin ash is in the secondary cyclone body, and quilt is driven rotary more fully, has further improved separating effect;
4. the downstream cyclone body is arranged on the inner space of upstream cyclone body, and the overall space of two stage cyclone is arranged and made the efficiency of dust collection height, and the pressure loss is little, and compact conformation.
