The cyclone separation dust cup is characterized in that a primary filer structure is that an external sleeve and an inner sleeve of a primary filter are arranged at a part below a main air inlet in a cup body, wherein the radial radius of the primary filter is reduced gradually downwards and a sidewall of the primary filter is sleeve-shaped; the external sleeve is provided with air inlets communicated with the main air inlet of the cup body; a dust fall mouth is arranged between the external sleeve and the inner sleeve and communicated with a large-particle dust collection cavity at an external layer of the bottom of the cup body; and a secondary cyclone separator structure is that a cyclone body sleeve is arranged above the primary filter, and secondary cyclone separator units are arranged inside the primary filter, wherein the secondary cyclone separator units are distributed circumferentially and the central axes of the secondary cyclone separator units are inclined outwards; the secondary cyclone separator units are connected in parallel to form a secondary cyclone separator and connects a lower dust mouth with a small-particle dust collection cavity at an inner layer of the bottom of the cup body by a central tube; and outlets of the secondary cyclone separator units are converged by a tertiary filter and connected with a main air outlet of a dust cup cover. The overall structure of the cyclone separation dust cup is reasonable and practical and has the advantages of small air resistance and high separation efficiency.
Description
Technical field
The utility model relates to a kind of cyclone separation dust cup of dust catcher, especially a kind of dirt cup of cyclone separating.
Background technology
The dirt cup that filters usefulness is the critical piece in the dust catcher, and in order better to realize separating of the impurity such as dust and air, existing dust catcher adopts the cyclone dust cup of secondary separation more.The air that contains impurity tangentially enters 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 large 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 enter 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 by filter elements such as sponges.
Be the cyclone separation dust cup that 201110400853.0 Chinese patent discloses a kind of dust catcher such as the patent No., comprise the cup that has tangential first order air inlet on the sidewall, the dirt bowl cover with air outlet and the cyclonic separation body that is arranged in the described cup with described cup coupling, it is characterized in that, described cyclonic separation body comprises main body, the sidewall middle part of described main body is provided with a plurality of second level air inlet, the edge, position, middle and lower part of described main body is connected with cyclonic separation body dust-blocking cover, below described cyclonic separation body dust-blocking cover, be first order dust-collecting cavity between cyclone separator lower wall and the cup, consisted of first order separator; There are a plurality of cyclonic separation cores to be distributed in the cyclonic separation core print seat around the described main body inside upper part, be provided with the air guide member with air inlet duct on the described cyclonic separation core, to import subordinate's separator from described cyclonic separation core air-flow out, the sidewall middle part of described 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, below described cyclonic separation core dust-blocking cover, the space is second level dust-collecting cavity between main body inboard and the subordinate's separator, has consisted of second level separator; Described cyclonic separation body center is provided with the center cyclone separator, as third level separator; The bottom of described cyclonic separation body and described center cyclone separator and described cup is fixed; This class cyclone separation dust cup mainly exists defective to be that the one-level whirlwind directly rotates in dirt cup main body, because the dust of deposition and the whirlwind of rotation are on the same surfaces of revolution, the dust of deposition in use also can other back whirlwind take away, enter the second-stage separator from aperture, the separating effect of primary separator is poor, has strengthened greatly the pressure of second-stage separator; The dust fall mouth of secondary cyclone directly facing to the granule dust laying dust chamber at center, so also cause easily the air-flow of dust again to carry, causes separative efficiency to descend;
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 form the air-out road junction, bowl cover seat downside has the one-level dust separator, the dust-separation ring is arranged at one-level dust separator bottom, its inboard, the upper end arranges the cyclone cylinder of spirality air inlet duct, the inner chamber top of cyclone cylinder is provided with the conical secondary dust separator with screen pack, 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, there is unavoidably a small amount of not separated air directly to enter the air inlet of secondary dust separator from the one-level dust separator with air-flow, cause the workload of the second-order separation to increase, and screen pack is set directly at the dust-collecting cavity top, cause easily the dust kicked up to enter from the mesh of screen pack, thereby stop up the secondary dust separator, inferior separating effect impacts use.
