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.

The specific embodiment
The present invention includes the whirlwind dust storage chamber 1 for vacuum cleaner 2.The first preferred embodiment of dust storage chamber 1 now will be discussed, and the second preferred structure will be discussed in back.In the first preferred structure, the wall 5 that whirlwind dust storage chamber 1 has the top 3 relative with base 4 and extends between base 4 and top 3.The cross section of whirlwind dust storage chamber 1 is roughly parabola or generally tubular, at top end, has the hemisphere official hats and canopies.The inner surface 6 on wall 5 and top 3 is roughly level and smooth and not interrupted.What from base 4, extend internally is flow pass 12, and flow pass 12 ends at tap hole 7, and tap hole 7 allows air to leave whirlwind dust storage chamber 1.Flow pass 12 preferably separates tap hole 7 with base 4.In a preferred embodiment, tap hole 7 will lead to fan 8, and fan 8 will produce the suction for vacuum cleaner.Being arranged in flow pass 12 and tap hole 7 tops and extending in whirlwind dust storage chamber 1 is filter 9.Filter 9 is taper or parabola shaped cross section preferably.The outside of filter 9 is equally preferably roughly level and smooth.Any supporting rib 10 grades will preferably be arranged in filter 9 inside.Flow pass 12, tap hole 7 and filter 9 preferably centrally are arranged in whirlwind dust storage chamber 1.Filter 9 should construct and be arranged so that air can not pass through to arrive flow pass 12 from whirlwind dust storage chamber 1 under not by the prerequisite of filter 9.
The air that enters whirlwind dust storage chamber 1 via ostium 11 must advance to tap hole 7 from ostium 11.The smooth surface of wall 5 will be carried the air in crooked route and the chip that enters whirlwind dust storage chamber 1 secretly.Wall 5 is followed from ostium 11 to tap hole 7 in this path, thereby the air in whirlwind dust storage chamber 1 applies the tornado flow pattern.Because the air that enters into whirlwind dust storage chamber 1 can little by little change direction rather than change immediately direction when entering into whirlwind dust storage chamber 1 on the length of whirlwind dust storage chamber 1, so air stream does not shrink and air stream is still laminar flow roughly when air enters whirlwind dust storage chamber 1.This allows air stream substantially not slow down through whirlwind dust storage chamber 1, and this allows more air stream within the unit interval through vacuum cleaner 2, to strengthen by this intensity of vacuum cleaner 2 then.
As mentioned above, wall 5 and on low degree more the smooth surface on top 3 will make the air and the chip that enter whirlwind dust storage chamber 1 follow the whirlwind pattern at it around whirlwind dust storage chamber 1 when ostium 11 moves to tap hole 7.The centripetal force caused by this whirlwind path outwards promotes the booty in air stream and chip towards wall 5 and away from filter 9.This will make booty and the chip can blocking filter 9, thereby the life-span that has strengthened filter 9 keeps the intensity of vacuum cleaner 2 simultaneously.
Lacking obstruction and will prevent from forming vortex in these zones on wall 5 and top 3.Similarly, the smooth outer surface of filter 9 will prevent from forming in its surface vortex.This will be for keeping the laminar flow tornado flow in these zones.Yet the base 4 of whirlwind dust storage chamber 1 is not interrupted.Preferably configure the bight of point relatively at wall 5 junction bases 4 and flow pass 12 from the position of base 4 extensions.Configurable other barrier equally there.This will make and form vortex near base 4.Chip will drop in these vortexs from cyclonic airflow.Depend on the position of whirlwind dust storage chamber 1 with respect to gravity, the chip dropped from air stream drops into base 4 or falls back in air stream.It should be noted in the discussion above that the chip dropped on base 4 will be from tap hole 7 and filter 9 skews.Advance to filter 9 for the chip be deposited on base 4, chip must be through cyclonic airflow, and this cyclonic airflow will be tending towards via centripetal force, chip being driven away from filter 9, as described above.Whirlwind dust storage chamber 1 should be opened, preferably at base 4 places or approach base 4 and open, so that any dust and the chip that allow to be collected in whirlwind dust storage chamber 1 are dropped.
In a preferred embodiment, fan 8 directly is arranged in the downstream of whirlwind dust storage chamber 1.Yet, should be understood that, a plurality of whirlwind dust storage chambers can be set in order, make one or more whirlwind dust storage chambers be arranged on the downstream of whirlwind dust storage chamber 1 and the downstream that fan is arranged on all whirlwind dust storage chambers.
In a preferred embodiment, whirlwind dust storage chamber 1 is illustrated in 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 the second preferred embodiment of the present invention, dust storage chamber 1 will be to be 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, in a plurality of sidewalls 5, produce cyclonic airflow.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 be discussed later, cavity 34 will hold flow nozzle 33, and the layout of cavity 34 and structure will make nozzle 33 roughly outside the cyclonic airflow path in dust storage chamber 1.In a preferred embodiment, cavity 34 is shapes of square or rectangle roughly.
Continue the 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 should roughly be filled cavity 34, and the top surface 33e that also should the be arranged so that nozzle 33 shrinkage pool 5a of closed side wall 5 roughly, to prevent air, enters into cavity 34.Flow nozzle 33 also ends in the hole 33b that direction valve 33c covers, and the angle of curved surface that direction valve 33c is configured to roughly to be tangential to the sidewall 5 of dust storage chamber 1 releases air in whirlwind 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 usually uses together with bent nozzle.With reference to figure 6A.Yet the placement of direction valve 33c and angled aperture are creationary parts of the present invention, this will be further elucidated hereinbelow.
In use, the whirlwind dust storage chamber 1 that has a 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 the whirlwind dust storage chamber 1 that is parallel to flow channel 13 the body region 33a that then enters into flow nozzle 33.By 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 approaches sidewall 5 and will make air be traveling in dust storage chamber 1 on every side and the top surface 33e of process nozzle 33 with the whirlwind path.Therefore, position, the valve 33c angled part aperture of nozzle 33 in the cavity 34 of dust storage chamber 1 and the curved surface of sidewall 5 are all preferred features of the present invention, and mutually combine to realize the tornado flow pattern for the air in dust storage chamber 1.After forming this whirlwind pattern, nozzle 33 is only by minimum the flowing type that affects.As mentioned above, the location of cavity 34 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 roughly prevent 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 from putting into practice of prior art; Therefore as mentioned above, in the practice of prior art, the main body of nozzle 33 does not remain on outside air stream, and can work as the physical barrier of the cyclonic motion of air.Referring to Fig. 6 B.Therefore, roughly smoothly not interrupted by the inner surface 6 that makes sidewall 5 and top 3, and, by eliminating any gap between nozzle 33 and sidewall 5, can more effectively keep around the cyclonic motion of filter 9.This prevents that dust, chip and other particle from dropping in filter 9 and blocking filter 9 then.Thus, globality and the life-span of filter 9 will be maintained.
Any annex 14 in 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), fixing brush and motor drive.Add any this instrument and will weaken necessarily the intensity of vacuum cleaner to vacuum cleaner, because they have increased the outside of vacuum cleaner and the distance between vacuum source (that is, fan).Yet, because whirlwind dust storage chamber 1 is more more effective than comparable cyclone filter, therefore in the vacuum cleaner that comprises whirlwind dust storage chamber 1, will have how available vacuum draw.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, effectively to operate annex.
Although 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.
