Abstract
The utility model provides a centrifugal high efficiency filter, comprising a casing, a top cover, and a base. The inner cavity of the casing is divided into a centrifugal chamber and a dust collection cavity two parts via a baffle. The bottom of the centrifugal chamber is provided with a tilted guiding plate. The contacting point of the guiding plate with an air passage communicated with an air inlet is in tangency. Between the centrifugal chamber and the dust collection cavity a via hole is provided. The center of the centrifugal chamber is provided with an air duct. The bottom of the air duct is close to the base; the end part of the air duct crosses a center hole of the guiding plate and extends upward. The base is a porous plate and is provided with a sponge or a filtering medium composed of a lamination of multilayer filtering paper and filtering cloth. The utility model which eliminates the dust bag or the Hy-Pak filtering element necessarily used in the traditional filtration, has the advantages of good dust absorption effect, easy production, convenient cleaning, and non discharging of fine dust, prolonging the service life of the vacuum cleaner. By using the guiding plate on the bottom of the centrifugal chamber, the airflow entering in tangential line generates backspin and rising; underthe effect of the centrifugal action, the dust entering the dust collection cavity deposits on the bottom of the dust collection cavity.
Description
Technical field
The utility model relates to a kind of centrifugal type filter, and especially a kind of is the centrifugal high effective filter of the matching used no extra large handkerchief filter core of vacuum cleaner, dustless bag.
Background technology
Existing dust catcher all is that the dust that will suck gathers, is collected in the filter bag that places in the vacuum cleaner; this dirt bag made from filter cloth or filter paper; along with increasing of access times; dust constantly gathers; the mesh of filter bag can be blocked; make it filter the ability drop of dust, even can produce micronic dust discharging phenomenon, influence the result of use of dust catcher.The disposable use of paper dirt bag, consumptive material is big, and the cost height cleans trouble though cloth dirt bag is reusable.In order to change this present situation, the dustless bag type filter of various novelties is come out one after another.The patent No. is " ZL03262119.1 ", " rotary type efficient filter ", cancelled the dirt bag exactly, extra large handkerchief filter core is placed on the centrifugal chamber center, air communication is crossed the coarse strainer outside, the fraction dust granules enters internal layer sea handkerchief filter core with the air-flow that circles round, in most of dust finally is deposited at the bottom of the dust storage chamber.This extra large handkerchief filter core is that a filter cloth or folded filter paper form, and area is bigger during expansion, is easy to simultaneously the fine dust brought by air again, and for example the brush powder of motor of dust collector wearing and tearing etc. blocks, thereby influences the dust collection efficiency and the service life of dust catcher.
Summary of the invention
The purpose of this utility model is at above-mentioned the deficiencies in the prior art and defective for the dust catcher industry provides a kind of both dustless bag, not have the high efficiency particulate air filter of extra large handkerchief filter core again.
The technological means that the utility model is taked is: this centrifugal high effective filter, comprise housing, loam cake and base, dividing plate is separated into centrifugal chamber and dust-collecting cavity two parts with the housing inner chamber, and the centrifugal chamber bottom is provided with guide plate, and air flue that communicates with air inlet and guide plate are tangent mutually; Described guide plate is obliquely installed in centrifugal chamber; Between centrifugal chamber and dust-collecting cavity, be provided with the hole that interconnects; Be provided with wireway at the centrifugal chamber center, base is approached in the bottom of this wireway, and its end is passed the guide plate centre bore and extended upward; Described base can be made up of porous plate, is placed with the filter material that sponge or multilayer filter cloth, filter paper are formed by stacking on porous plate.The air-flow that has dust enters from tangential direction under centrifugal chamber, the guiding of air-flow at guide plate through air flue, circle round along the centrifugal chamber inwall, and form the gyration airflow that rises, and make the dust granules of suction under action of centrifugal force, enter dust-collecting cavity, final settlement is at the bottom of the chamber.
The utility model compared with prior art, cancelled dirt bag or rotary extra large handkerchief filter core that conventional filter must be used, it utilizes the guide plate of centrifugal chamber inner bottom part, and the air-flow that tangent line is entered produces the rising of circling round, because action of centrifugal force, dust is entered on dust-collecting cavity is deposited at the bottom of the chamber.Its cost is low, it is convenient to make, clean, and the pick-up performance of dust catcher is improved greatly, prolonged the service life of dust catcher.

The specific embodiment
Shown in the accompanying drawing 1～5, this centrifugal high effective filter comprises housing 2, loam cake 1 and the base 4 of filter.Have air inlet 6 on housing, dividing plate 12 is divided into centrifugal chamber 10 and dust-collecting cavity 3 two parts with the housing inner chamber.Shown in the present embodiment figure, centrifugal chamber 10 is drum shape, and centrifugal chamber drum shape outer wall is separated centrifugal chamber and dust-collecting cavity 3.The centrifugal chamber bottom is provided with porous, and the bottom of close centrifugal chamber 10 is provided with a guide plate, and this guide plate is obliquely installed in centrifugal chamber, and air inlet 6 is opened on the housing 2, and air flue 7 is arranged in the air inlet 6, and this air flue 7 is tangent with guide plate 8 engagements.The centrifugal chamber center is provided with wireway 9, and base is approached in its bottom, and the centre bore that guide plate 8 is passed in its end extends upward.Air-flow is by tangentially entering, and under the guiding of guide plate, it is mobile to circle round along the centrifugal chamber inwall, forms gyration airflow.Be provided with the through hole 13 that is interconnected between centrifugal chamber 10 and dust-collecting cavity 3, base is to be made by porous plate 11.The filter material 5 that on this porous plate, is placed with sponge or is formed by stacking by multilayer filter cloth, filter paper.
The air that has dust enters from air inlet, enter centrifugal chamber 11 through air flue 7 by tangential direction, under guide plate 8 guiding on inclined plane, circle round rising and form gyration airflow along the centrifugal chamber inwall, make the dust granules of suction produce centrifugal force, and enter dust-collecting cavity 3 by through hole 13, sink to the dust-collecting cavity bottom and pile up.Meanwhile, air through the hole of wireway 9 and centrifugal chamber bottom, pass filter material 5 and base porous plate 11 enters the dust catcher electric fan.The wireway 9 that has only minute quantity molecule dust to cross in the centrifugal chamber with circulation of air enters on the base of centrifugal chamber bottom, is adsorbed by filter materials such as sponges.As long as the porous plate 11 of dismounting base can conveniently take out filter material such as sponge and clean.
