Abstract
The present invention relates to an improved cyclonic chamber for air filtration devices. A cyclonic chamber for use in air filtration devices. The chamber includes an apex opposite a base with sidewalls extending therebetween. The cyclonic chamber is preferably parabolic in cross-section or tubular with a hemi-spherical cap. The base contains an outflow passage and a conical filter extending therefrom. An inflow passage is provided proximate the apex. The inflow and outflow passages are parallel but not aligned. The chamber interior is smooth. The smooth interior and offset relationship of the inflow and outflow passages causes air to take a cyclonic path between the inflow passage and the filter. Debris in the airstream is pushed outward - away from the filter - by centripetal force. Eddies form proximate the base. Debris escapes the airstream there, where it either remains or, depending upon the chamber's orientation relative to gravity, falls back into the airflow where it is again directed away from the filter.

In a preferred embodiment, whirlwind dust storage chamber 1 is illustrated in the hand-held vacuum cleaner.Yet, should be understood that whirlwind dust storage chamber 1 can be used for any traditional vacuum cleaners system or air filtering system.
In second preferred embodiment of the present invention, dust storage chamber 1 will be being configured to the roughly the same mode of aforementioned discussion, that is, dust storage chamber 1 will be limited by base 4, top 3 and a plurality of sidewall 5, produce cyclonic airflow in a plurality of sidewalls 5.Yet in this embodiment, sidewall 5 will comprise shrinkage pool 5a and cavity 34 will hang from the wall 5 at shrinkage pool 5a.As will discussing later, cavity 34 will hold flow nozzle 33, and the layout of chamber 33 and structure will make nozzle 33 roughly be in outside the cyclonic airflow path in the dust storage chamber 1.In a preferred embodiment, chamber 34 is shapes of square or rectangle roughly.
Continue second preferred embodiment of the present invention is discussed, flow nozzle 33 will be communicated with flow channel 13.Flow nozzle 33 also will comprise the curved body zone 33a with top surface 33e.Flow nozzle 33 is filled chamber 34 roughly, and the top surface 33e that also should the be arranged such that nozzle 33 shrinkage pool 5a of closed side wall 5 roughly, enters into cavity 34 to prevent air.Flow nozzle 33 also ends among the hole 33b that is covered by direction valve 33c, and direction valve 33c is configured to release air in the whirlwind dust storage chamber 1 with the angle of the curved surface of the sidewall 5 that roughly is tangential to dust storage chamber 1.In a preferred embodiment, direction valve 33c comprises rubber valve plate 33d.The rubber valve plate is known in the art and uses with bent nozzle usually.With reference to figure 6A.Yet the placement of direction valve 33c and angled aperture are creationary parts of the present invention, and this will be further elucidated hereinbelow.
In use, the whirlwind dust storage chamber 1 with cavity 34 can be used for any hand-held vacuum cleaner main body.Yet, should be understood that, the unnecessary vacuum cleaner that is confined to of vacuum source, and dust storage chamber 1 can be used for any suitable high-speed air cleaning system.
In operation, air will enter into whirlwind dust storage chamber 1 that is parallel to flow channel 13 and the body region 33a that then enters into flow nozzle 33.With generation whirlwind as described below path.The power that air moves through the body region 33a of nozzle 33 will make the valve 33c of nozzle 33 become partly with directionality open, make air to leave nozzle 33 with the angle of the curved surface of the wall 5 that roughly is tangential to dust storage chamber 1.Tangential introduction of air will make air be traveling in the top surface 33e that dust storage chamber 1 also passes through nozzle 33 on every side with the whirlwind path near sidewall 5.Therefore, nozzle 33 in the cavity 34 of dust storage chamber 1 the angled part aperture of position, valve 33c and the curved surface of sidewall 5 all be preferred feature of the present invention, and mutually combine and realize tornado flow pattern for the air in the dust storage chamber 1.After forming this whirlwind pattern, nozzle 33 only will influence flowing type minimumly.As mentioned above, the location of cavity 33 and structure will make nozzle 33 roughly outside the cyclonic airflow path in dust storage chamber 1.In addition, similarly, as described above, the top surface 33e of nozzle 33 will prevent roughly that air from entering into cavity 34.Adopt this mode, will keep the cyclonic airflow pattern.In order further to strengthen the cyclonic motion of air, any gap between the wall 5 of nozzle 33 and dust storage chamber will preferably minimize or be eliminated, to prevent in these zones the formation vortex and to keep the laminar flow tornado flow.
The preferred structure of the dust storage chamber 1 of above-mentioned discussion is different with putting into practice of prior art; As mentioned above, in the practice of prior art, the main body of nozzle 33 does not remain on outside the air stream, and therefore can work and be the physical barrier of the cyclonic motion of air.Referring to Fig. 6 B.Therefore, by making the inner surface 6 on sidewall 5 and top 3 roughly smoothly not interrupted, and, can more effectively keep centering on the cyclonic motion of filter 9 by eliminating any gap between nozzle 33 and the sidewall 5.This prevents that then dust, chip and other particle from dropping in the filter 9 and blocking filter 9.Thus, the globality and the life-span of filter 9 will be kept.
Any annex 14 in the various traditional vacuum cleaners annexes can be added to the upstream of flow channel 13.Annex 14 comprises the rotating brush that flat suction nozzle (crevice tools), the brush of fixing and motor drive.Add will weaken necessarily to the vacuum cleaner the intensity of vacuum cleaner of any this instrument, because they have increased the outside of vacuum cleaner and the distance between the vacuum source (that is fan).Yet,, therefore in the vacuum cleaner that comprises whirlwind dust storage chamber 1, will have how available vacuum draw because whirlwind dust storage chamber 1 is more more effective than comparable cyclone filter.Net result is that the vacuum cleaner that comprises whirlwind dust storage chamber 1 should can provide necessary suction better than the comparable vacuum cleaner that comprises conventional cyclone filter, to operate annex effectively.
Though the present invention is described by its preferred embodiment, for consulting the later those skilled in the art of above stated specification, other embodiment will be apparent.These embodiment and preferred embodiment will be intended to be included in the spirit and scope of aftermentioned claim.
