During hand-held cleaning device use, user can lift hand-held sanitizer cartridge by holding handle It sets, then by the opposite place to be cleaned in gas access, then can star air-flow generating unit, it can after air-stream generating device starting So as to generate negative pressure inside dust and gas separative unit, it is single can be drawn into dust and gas separation by gas access for extraneous dirty air at this time In member, separated in a manner of cyclonic separation, by dirty air sundries and dust separate and be collected in a manner of expecting In the chamber set.By the above process, the dust suction cleaning operation of hand-held cleaning device is realized.

It is improved in major technique of the invention and in one embodiment with reference to Fig. 1 depicts dirt for dust and gas separative unit Each component parts of gas separative unit, these component parts assemble along direction indicated by lines in figure for dust and gas separation Unit, the dust and gas separative unit shape after assembling can refer to the structure shape of the middle section for the hand-held cleaning device that Figure 12 is painted Shape.

In Fig. 1, dust and gas separative unit includes cyclonic separation portion 600, and cyclonic separation portion 600 is equipped with multiple small volumes The whiz device being connected to parallel depicts multiple rotations in figure with reference to the part-structure of Fig. 6 slave cyclonic separation portion 600 fractionation being painted General shape and arrangement from device 6101, the serrated end (one end of whiz device upward in figure) of whiz device 6101 are ash discharge Mouthful, the other end is clean air outlet and tangential gas access (not shown), in conjunction with Fig. 1, in the outside wall portions of each whiz device 6101 Subregion is equipped with flexible strutting piece, specifically, each whiz device will after filter mantle 500 assembles before cyclonic separation portion 600 and motor The flexible strutting piece for being attached to filter mantle 500 before motor is supported, with reference to Fig. 2, in support construction 800, and flexible strutting piece 810 The position setting of corresponding whiz device.

Flexible strutting piece 810 is pointedly arranged in the partial sidewall of each whiz device 6101, is realized to the soft of whiz device Property support revolved for using the hand-held cleaning device of parallel arranging multiplayer whiz device to improve cyclonic separation effect The flexible strutting piece of bumper and absorbing shock function is realized in outer wall setting from device, is not only had and is reduced whiz device Oscillation Amplitude holding structure Stable effect, and noise caused by capable of reducing because of gas shock.Moreover, between whiz device, whiz device and support construction Between take filling ground mode flexible strutting piece is set, play buffer function between each functional unit, avoid occur rigidity rub It wipes or contacts, with improving each functional unit fastness and stability.

In addition, flexible strutting piece is arranged between whiz device with filling mode, also there is reduction assembly precision to require excellent Point due to being grouped, divides inside and outside level arrangement by the cooperation deviation allowed between each functional unit in one significantly range Whiz device, which determines, necessarily more complicated structure inside cyclonic separation portion, therefore just needs to reduce each section as much as possible Manufacture difficulty and assembly difficulty realize the support of part in a flexible manner, and in assembling process, what flexible portion can be temporary goes out Existing elastic deformation, allow between component by less stringent installation path can structure together, then, elasticity occurs The part of deformation springs back filling, can be stably positioned, this is advantage not available for rigid structure.

In addition, in a preferred embodiment, partial sidewall above-mentioned is located adjacent to the position of the ash hole of whiz device, specifically For, the position for forming flexible support contact is no more than 50mm at a distance from ash hole, Support Position limited in this position, by The pyramidal structure possessed by whiz device, the position near ash hole are to be passed through flexibility to big by gas shock intensity Support construction buffering, avoid impact transmitting, also by flexible support formed for whiz device since gas shock causes Vibration resistance, reduce the amplitude of vibration, while reducing resulting noise.In addition, support flexible is different from rigidity Support, rigid support are to limit the vibration of whiz device, and the dynamics of impact is allowed to transmit until support construction, needs support construction to have Biggish size also just will be correspondingly arranged in biggish rigidity, not then be possible to be difficult to keep stable.In addition, whiz utensil There is revolving body to obtain outer wall, in the case that it is some need that air-tightness is kept to obtain, it is more difficult to sealing device is set, and by flexible support structure It is set as complete loop, then can have both the effect of sealing while support.So flexible support structure is supported whiz device Region be disposed proximate to the position of ash hole, can effectively buffer the vibration of whiz device generation, and be conducive to keep stablizing, and And be conducive to improve the air-tightness of device.

Referring again to FIGS. 6, at least supporting the flexible strutting piece 810 of adjacent whiz device to be integrally formed, by flexible support Adjacent whiz device is connected as modular construction by structure 810, the vibration for a part of whiz device that can cancel out each other, and flexible Although supporting element 810 has determining shape, because having flexibility to be easy to happen deformation, deposited relative to as individually unit Flexible strutting piece, several flexible strutting pieces are integrally formed, and the shape that can increase flexible strutting piece to a certain extent is true Determine degree, avoids in assembling process because softness increases assembly difficulty.Depicted in figure is three adjacent whiz devices of support Flexible strutting piece be integrally formed, the flexible strutting piece of two whiz devices that respectively support is arranged in outer layer is arranged in support The flexible strutting piece of one whiz device of internal layer.In a further embodiment, it can be adjusted according to the arrangement of whiz device It is whole, the flexible strutting piece of adjacent two or more than three whiz devices will be supported to be integrally formed, can equally be played aforementioned Effect.

Preferably implement mode as above-described embodiment, corresponding, the arrangement of whole whiz devices are as follows: it include around The the first whirlwind group and the second whirlwind group that axis is arranged parallel, wherein the ash hole of the first whirlwind group is located at the first height region, The ash hole of second whirlwind group is located at the second height region, and the second height region is located at the first height region top；And it is soft Property supporting element correspondingly includes the first support group for being used to support the first whirlwind group and second that is used to support the second whirlwind group Support group, similarly, the second support group height are higher than the first support group；With reference to Fig. 2, in figure, it is two groups that flexible strutting piece 810, which is divided to, Five be located above are the second support group, and underlying ten are the first support group, per adjacent two first Flexible strutting piece in support group is linked together with the flexible strutting piece in a second support group.

The shape and arrangement of flexible support structure are specifically provided in embodiment depicted in attached drawing, for each For whiz device, ash hole or the sidewall sections close to ash hole are wrapped up or are surrounded by flexible strutting piece, moreover, flexible The partial sidewall of supporting element is actually to be extruded between the adjacent whiz device in part, thus has both the work of buffering and support With, the side wall of the flexible strutting piece in especially the second support group, while supporting the first whirlwind group to neutralize second by flexible contact Whiz device in whirlwind group improves the compactedness arranged inside device.

From the figure, it can be seen that each flexible strutting piece includes the through-hole 860 for passing through or wrapping up whiz device ash hole, and It is used to support the side wall 870 of whiz device outer wall.This is a kind of illustrative arrangement, and ash hole passes through through-hole 860 and mainly protects Hinder air-tightness, and the side wall 870 of whiz device outer wall is supported then mainly to play buffer shock-absorbing effect.In the structure being painted in figure, Through-hole 860 can be formed in top one end of side wall 870, and ash hole passes through through-hole 860, and the channel that side wall is formed then constitutes The extension of ash hole, air-flow hit side wall 870 flexible when spraying from ash hole, will reduce the amplitude of vibration, also reduce noise. And in a further embodiment, through-hole can also be formed in the one end of side wall on the lower, to enhance the reliability of flexible support, or Through-hole is formed in the middle part of side wall.

In addition, illustratively depicting the composition and arrangement of the second whirlwind group (inverted), the second whirlwind group in Fig. 6 In each whiz device 6101 be connected and fixed by frame, the first whirlwind group includes more whiz device, and each whiz device is same It is connected and fixed by frame, in some embodiments, the frame in the first whirlwind group forms the part enclosure in cyclonic separation portion, i.e., It is directly exposed to the external world, the outer wall of the whiz device of the second whirlwind group also forms the part enclosure in cyclonic separation portion, i.e., directly It is exposed to the external world.

And in order to optimize the structure of flexible strutting piece, and it is made to play effect more buffer shock-absorbing and supporting role, ginseng Fig. 2 is examined, mode is preferably implemented as above-described embodiment, the bracket 840 for fixing flexible strutting piece 810 is also provided, is such as schemed, At least partly region of the side wall 870 of flexible strutting piece 810 is fixedly connected with bracket 860.Bracket 860 is arranged to rigidity and is greater than Thermoplastic elastomer (TPE), TPU, silicon rubber, natural rubber or other things can be selected in flexible strutting piece 810, such as flexible strutting piece Suitable low-temperature setting elastomer is formed, and bracket is then formed using the plastics (such as ABS) with centainly rigidity, while bracket can To be set as the structure of similar strip, it is made to have both certain rigidity and elasticity.

It is highly preferred that flexible strutting piece 810 is by sticking or encapsulated moulding process is linked together with bracket 840, bracket 840 affixed dust gathering arresters 500 or the outer wall for being directly integrally formed (mold injection mode) and dust gathering arrester 500, bracket 840 are configured to The structure of similar skeleton, support flexible strutting piece 810 have more stable shape, the through-hole 860 for forming flexible strutting piece Substantially determining shape is kept, and due to the elasticity that bracket itself has by its shape, after being deformed for some reason, additionally it is possible to Automatically restore to the original state.Moreover, the setting being linked together, additionally it is possible to prevent flexible strutting piece from going out in assembling or repair demolition Active can also prevent in assembling or disassembly process, and the reduction flexible strutting piece interface unrelated with other as far as possible connects Touching, avoids the occurrence of the CONTACT WITH FRICTION and pollution that do not expect, keeps the stabilization and cleaning of flexible strutting piece.

It has been observed that preferably, the flexible strutting piece of every two the first support group and the flexible of the second support group prop up Support member constitutes a group, the integrated molding of the flexible strutting piece of each group；In other feasible embodiment, it can also use Other combinations are also possible to the flexibility of the flexible strutting piece and a second support group in one or more first support groups Supporting element constitutes an integrally formed group, this is relevant with the arrangement of whiz device to a certain extent, and the present invention is not The building form of the quantity of limitation group and each group.

Preferably, the flexible strutting piece in each group is not only integrally formed but also bracket is cooperated to form the knot with air-tightness Structure pass through air-flow can only between group, and such as Fig. 2, airflow channel 850, these gas are thus formed between adjacent group Circulation road 850 is configured to shape and section is roughly equal, and air-flow can be made equably to be shunted, and cooperates these airflow channels 850 flowings in air-flow cavity dirty air can be entered in each whiz device relatively uniformly.In addition, cooperation whiz device circumference The arrangement of homogeneous phase pair, by this arrangement, the vibration for also allowing each whiz device to generate mutually transmits one by flexible strutting piece Part, cancelled each other out a part in a manner of liquidating, and reduces whole Oscillation Amplitude.

In addition to this, with reference to Fig. 3, the embodiment of the present invention, which is also provided, excludes dust by each whiz device ash hole for collecting Dust gathering arrester 400, dust gathering arrester 400 has the chamber 410 to collect dust that is limited by dust cover outer wall, the upper end 420 with Bracket 840 above-mentioned accordingly combines, with reference to Fig. 2, in bracket 840 and 400 binding site of the dust gathering arrester (position of corresponding upper end 420 Set and shape) be equipped with first seal 820, and first seal 820 and flexible strutting piece 810 are integrally formed, and the first sealing Part 820 and the material having the same of flexible strutting piece 810 and substantially consistent moulding process, are linked together with bracket, By the rigid reinforcement of bracket.Due to equally existing air-flow inside chamber 410, and the ash hole of each whiz device is all at a high speed by dust It sprays, the gas shock in chamber 410 can equally cause to vibrate, since dust gathering arrester 400 has relatively large size, the vibration Noise may be mainly brought, therefore, goes out to increase flexible structure in upper end 420, buffer function can be played, reduce noise.Also, It can ensure the air-tightness of the binding site of bracket 840 and dust gathering arrester 400.In addition, first seal 820 and flexible strutting piece 810 are integrally formed, and constitute support system, are each attached to bracket 840, play whole buffer function, have shown in figure, by whiz The arrangement of device determines that the junction shape of binding site is more complicated, and the structure of integral type advantageously ensures that comparison determines Shape, assembling when, can reduce work difficulty, and have both anti-lost, antipollution advantage.

In addition, the common configuration as hand-held cleaning device is often set for the motor in protection air-flow generating unit It is filtered before setting motor, in one embodiment, dust and gas separative unit is equipped with filtering chamber before motor, to accommodate mistake before motor Filter body 700.

In conjunction with Fig. 1, Fig. 2 and Fig. 6, specifically, the lower part of filtering chamber is by 500 shape of filter mantle before motor before aforementioned motor At, and filter mantle 500 is at least partially disposed in inside dust gathering arrester 400 before motor, is filtered before filter mantle upper end and motor before motor The top 610 of chamber is incorporated into the lower end 6102 on top 610, and the corresponding binding site is equipped with second seal 830, and second is close Sealing 830 and flexible strutting piece 810 are integrally formed.It is aforementioned right that molding mode, structure and the effect of second seal 830 can refer to In the introduction of first seal, it is clear that entire integrally formed structure is more advantageous to molding and assembling.And with implementation above-mentioned If example combines, then flexible strutting piece 810, first seal 820 and 830 three parts of second seal can form whole delay Sealing structure is rushed, this cushion seal structure plays a role as a whole.

In addition, the outer wall 510 of filter mantle 500 limits two chambers simultaneously before motor as we can see from the figure, first is that accommodating The first chamber of filtering core 700 before motor, another is the second chamber as gas passage after filtering being connected to first chamber Room, accordingly, top 610 also limit two chambers, one be before accommodating motor jointly with first chamber filtering core 700 by The third chamber 6104 that chamber outer wall 6103 limits is filtered before motor, the other is leading to second chamber collectively as gas after filtering The 4th chamber 6106 limited by Gas outlet channels outer wall 6105 in road, as the 4th chamber of figure is directly connected to air stream outlet 6107, gas will be from the air flow inlet (not shown) of 6107 inflow stream generating unit of air stream outlet.

As previous embodiment is introduced, in order to play buffering, vibration damping and sealing function, flexible strutting piece needs to have Good ductility and elasticity are suitable for the material used foregoing describes flexible strutting piece, and in order to make flexible support Part is reliably combined with bracket, also simplifies forming preparation process, flexible strutting piece, first seal and second seal preferably exist It after dust gathering arrester and rack forming, is molded and/or molds in a manner of low-temperature setting and/or mold is injected to be formed, pass through secondary mould Pressure directly obtains the shape of expectation, by the molding of flexible support structure and and as the combination outside the bracket and dust gathering arrester of skeleton It is realized, will be attached again compared to after being separately formed, more convenience by a process, also reduced accurate for assembling The requirement of degree reduces the work difficulty of assembling.Meanwhile the form and dimensional precision of flexible support structure is required opposite It is lower, it can permit dust gathering arrester and bracket and choose biggish tolerance in moulding process, reduce Mold Making cost.Certainly, exist In other embodiment, mold molding mode can also be taken through and form integrated flexible strutting piece, first seal and It after two sealing elements, then is connected together with dust gathering arrester and bracket for example, by the mode of bonding, but such implementation can It can need by more technological equipment.

In addition, support construction 800 is formed in filter mantle before motor, rather than it is formed directly into and accepts whiz device ash hole Dust gathering arrester can simplify and homogenize the molding difficulty of each section, compared to the formation support construction suitable for reading in dust gathering arrester, will prop up Filter mantle passes through assembling in conjunction with dust gathering arrester upper end again before support structure is set to motor, or support construction is fabricated separately, then with Filter mantle combines before dust gathering arrester and motor, can reduce the molding complexity and mould development, cost of manufacture of dust gathering arrester.

In addition, two groups of whiz devices are arranged around an axis, and the ash hole injection of each whiz device carries the gas of dust Stream, which is along, sprays into dust gathering arrester in the direction of smaller acute angle with the axis downwardly direction, thereby results in the gas for dust gathering arrester Stream impact, the noise that can equally generate vibration and be caused by vibration.

In a preferred embodiment, with reference to Fig. 1, Fig. 3 and Fig. 7, in hand-held cleaning device, around dust gathering arrester Separation bin 100 has and obtains the upper opening that upper end is located at sustained height region with dust gathering arrester, when assembling, tubular cover 200, antelabium Filter mantle 500 before part 300, dust gathering arrester 400, motor, cyclonic separation portion 600, after filtering core 700 is assembled into one before motor, It is fitted into separation bin 100 from upper opening.Separation bin 100 also has to exclude to open under the foul via separation bin initial gross separation Mouthful, and the lower cover of closing under shed is organized after integral each section protrudes into separation bin, the lower end 460 of dust gathering arrester 400 and lower end Lid realizes flexible connection by flexible connection end 470.As preferred implementation, there is opening at flexible connection end 470, and Lower cover forms boss that is corresponding and closing the opening, the lower ending opening of closing dust gathering arrester 400 and outer while flexible connection Fluid communication inside boundary or separation bin.Thus another fixed Support Position flexible is formed in the lower end of dust gathering arrester 400, Cooperation flexible strutting piece plays the effect of buffer shock-absorbing jointly, avoids the occurrence of the knot of " cantilever " of similar Relative Vibration hair positive position Structure reduces whole Oscillation Amplitude, eliminates the unfavorable contact therefore generated and noise.

Referring again to FIGS. 1, being carried out at cyclone type separation for multiple parallel connection whiz devices are arranged in cyclonic separation portion 600 Structure is managed, is highly desirable to arrange air-flow before air-flow enters whiz device, makes its homogenization, also, processed Air-flow is reduced in journey as far as possible to hit before entering whiz device with the inner wall of the airflow channel flowed through, dirty air is avoided to carry Grit is separated before entering whiz device with regard to some, and the position other than dust gathering arrester is adhered to or collects, this clearly not by What the producer and user were expected.Further, since tubular is covered with the effect of primary filter, filtered air-flow is also required to airtight The good passage flow of property enters whiz device.

In addition, channel and air-flow enter the necessary circulation passage before whiz device, cylinder to tubular cover with providing airflow The side wall of shape cover is inevitably by the impact of air-flow, it is also desirable to which it keeps stable shape, that is, has comparable rigidity, needs Increase rigidity to be often designed from structure, such as increases tubular cover thickness or increase the reinforcing rib structure of support；Or from material Material aspect is designed, and is made for example, by using the stronger material of rigidity, it is clear that the design of these two aspects all with hand-held sanitizer cartridge It sets pursuit lightweight to be conflicted, and hand-held cleaning device mainly passes through the purifying place that certain driving air-flow realizes dirty air Reason, changes of flow fields environment be likely to bring it is difficult to predict influence, it is obviously also inappropriate arbitrarily to increase reinforcing rib, and increasing Add reinforcing rib is equally possible can constitute some easy to attach or deposition dust position.
