Abstract
The invention discloses a cyclone separating type dust cup of a dust collector, which is provided with two-grade separators. A cyclone separating core structure is used for replacing a filtering mesh structure in secondary cyclone separation, and the problem that blockage is caused in a separating process and service of the dust cup is affected can be avoided; and a conical skirt edge or a conical surface is arranged in each cyclone separator, so that airflow is accelerated at the conical skirt edge or the conical surface, and then is suddenly decelerated after entering a lower enlarged space, and dust is settled and is prevented from flying and being taken away. The cyclone separating type dust cup of the dust collector is reasonable and practical in integral structure, small in air resistance and high in separating efficiency.
Description
Technical field
The present invention relates to a kind of dust cup of dust collector, especially a kind of dirt cup of cyclone separating.
Background technology
Filter the dirt cup uses and be the critical piece in the dust catcher, for separating of impurity such as better realization dust and air, existing dust catcher adopts the cyclone dust cup of secondary separation more.The air that contains impurity tangentially gets into first order separator; Do gyration from top to bottom; In turning course; Bulky grain, heavier impurity because of density greater than air, suffered centrifugal force big and collide lose that inertia falls into the below dust-collecting cavity behind the inwall of first order separator and and air separation.Thinner impurity and air get into second level separator, and tiny dust loses dust-collecting cavity and the air separation that inertia falls into the below after colliding the inwall of second level separator.And clean air is discharged in the atmosphere after through filter elements such as sponges.
Like Granted publication number is the disclosed a kind of dust separation cup of suction cleaner of Chinese patent of CN201219871Y; Bowl cover side and bowl cover seat form the air inlet of spirality air inlet duct; Bowl cover seat and bowl cover are formed the air-out road junction, and bowl cover seat downside has the one-level dust separator, and the dust-separation ring is arranged at one-level dust separator bottom; The whirlwind tube that it is inboard, the upper end is provided with the spirality air inlet duct; The inner chamber top of whirlwind tube is provided with the conical secondary dust separator of band screen pack, and its upper outside is provided with guide ring, and the middle part of one-level dust separator also is provided with guide ring.
Because one-level dust separator and secondary dust separator are in the same cavity volume; Have a small amount of not separated air directly to get into the air inlet of secondary dust separator from the one-level dust separator with air-flow unavoidably, the workload that causes secondary to separate increases, and screen pack is set directly at the dust-collecting cavity top; Cause the dust kicked up to get into easily from the mesh of screen pack; Thereby stop up the secondary dust separator, inferior separating effect impacts use.
Summary of the invention
Technical problem to be solved by this invention provides the vacuum cleaner cyclone separate type dirt cup that a kind of cyclonic separation is effective, dust collection efficiency is high.
The present invention solves the problems of the technologies described above the technical scheme that is adopted: a kind of vacuum cleaner cyclone separate type dirt cup; Comprise the cup that has tangential first order air inlet on the sidewall; Dirt bowl cover with said cup coupling with air outlet; And be arranged on the cyclonic separation body in the said cup, it is characterized in that
Said cyclonic separation body comprises main body; The bottom of said main body is provided with cyclonic separation body dust-blocking cover; Said main body is provided with a plurality of second level air inlet on the sidewall above the said cyclonic separation body dust-blocking cover, said main body below is provided with storage dirt bucket, below said cyclonic separation body dust-blocking cover; Be first order dust-collecting cavity between said storage dirt bucket and the said cup, above-mentioned parts have constituted first order separator;
Said cyclonic separation body top is provided with the cyclonic separation cup; A plurality of cyclonic separation cores are distributed in the cyclonic separation core print seat in the said cyclonic separation body; The air inlet duct of said cyclonic separation core print seat is communicated with said cyclonic separation body; The sidewall middle part of said cyclonic separation core offers third level air inlet; The edge, position, middle and lower part of cyclonic separation core is connected with cyclonic separation core dust-blocking cover, and the inboard space of the inboard and said storage dirt bucket of said cyclonic separation body constitutes second level dust-collecting cavity, and above-mentioned parts have constituted second level separator.
Said cyclonic separation body dust-blocking cover is arranged on the below of the above second level air inlet of said main body, is first order taper shirt rim.Air-flow quickens at place, the first order taper shirt rim of cyclonic separation body, and through behind this first order taper shirt rim, thereunder the space is strengthened suddenly and swirling eddy is slowed down suddenly, thereby impurity such as dust is deposited in the first order dust-collecting cavity from the air-flow of rotation.
Said cyclonic separation core dust-blocking cover is arranged on the below of said the above third level air inlet of cyclonic separation core, is taper shirt rim, the second level.Air-flow quickens at place, taper shirt rim, the second level of cyclonic separation core; Through behind this taper shirt rim, second level; Thereunder the space is strengthened suddenly and the air-flow of rotation is slowed down suddenly, thereby thinner impurity such as dust are deposited in the dust-collecting cavity of the second level from the air-flow of rotation.
Has chimney fan in the said main body; The top of said chimney fan is reverse frustoconic and extends said main body upper end and is connected with said cyclonic separation cup; Circumferentially be provided with axially extended air channel in the top of said chimney fan, said air channel and said cyclonic separation core print seat are staggeredly arranged.Make to enter into second level separator, carry out cyclonic separation through the tangential introduction of air behind the first order separator.
The upper end of said cyclonic separation core is provided with the leading arm that circles round, and cooperates with said air inlet duct, snaps onto in the said cyclonic separation core print seat, and the cyclonic separation core is limited in the cyclonic separation core print seat.
Be provided with first sealing ring between said air channel and the said cyclonic separation cup, said sealing ring shape and said air channel coupling get in the separator of the second level to guarantee tangential introduction of air.
The top of said cyclonic separation cup is provided with the air-out cover plate, offers a plurality of exhaust vents on the said air-out cover plate, makes that the cleaned air after separating flows out from the air-out cover plate.
Be provided with second sealing ring between said cyclonic separation cup and the said air-out cover plate, offer a plurality of perforates on said second sealing ring, cooperate with the upper end of said cyclonic separation core opening.Prevent that air from flowing out to the external world from the gap that connects from cup.
The lower edge of said air-out cover plate and said cup junction are provided with the 3rd sealing ring.Prevent that air from flowing out to the external world from the gap that connects from cup.
Compared with prior art, the invention has the advantages that: second level cyclonic separation has adopted the structure of cyclonic separation core to replace the structure of filter mesh, can avoid in separation process, resulting in blockage and influences use; In the cyclone separator of each grade, be provided with taper shirt rim or taper surface; Make air-flow slow down suddenly in this acceleration and the space below after this getting into, strengthened, make dust deposit avoid kicking up and be pulled away, reasonable integral structure is practical; Vapour lock is little, and separative efficiency is high.
