Describe according to the hand held cleaner 100 of the embodiment of the present invention below with reference to Fig. 1-Figure 13. Hand held cleaner 100Can be charge type, direct current class dust catcher, but be not limited to this.

As shown in Figure 1, according to the hand held cleaner 100 of the embodiment of the present invention, comprise housing 1, dirt cup 2 and electricityMachine 3.

On housing 1, be formed with air inlet 111 and blowing mouth 121, the contiguous air inlet 111 of blowing mouth 121 arranges. Dirt cup2 are located on housing 1, and dirt cup 2 is connected with air inlet 111. Motor 3 has motor cavity 31, motor cavity 31 and dirt cup2 communicate, after the airflow passes dirt cup 2 being entered by air inlet 111 and motor 3, flow out from blowing mouth 121.

For example, with reference to Fig. 1 and in conjunction with Fig. 8 and Figure 10, air inlet 111 and blowing mouth 121 are formed as rectangular substantiallyShape, air inlet 111 and blowing mouth 121 are all positioned at the front end (for example, the left end in Fig. 1) of housing 1, and air intakeMouth 111 and blowing mouth 121 each intervals are arranged. In the time that motor 3 moves, the interior generation negative pressure of motor cavity 31, makesThe air stream of such as dust-laden of outside dust-contained airflow etc. can enter in dirt cup 2 by air inlet 111, at dirt cup 2Under filtration, the dust in air-flow etc. is separated and is collected in dirt cup 2, and clean air-flow passes through motorChamber 31 is blown out by blowing mouth 121. Here, it should be noted that, direction " front " refers to hand held cleaner 100A side away from user, its rightabout is defined as " afterwards ", i.e. the user's handling of hand held cleaner 100One side.

Alternatively, blowing mouth 121 is positioned at the top of air inlet 111, but is not limited to this.

Alternatively, the cross-sectional area of blowing mouth 121 is less than the cross-sectional area of air inlet 111. Thus, by size is setRelatively little blowing mouth 121, the air-flow blowing out from blowing mouth 121 can be with certain flow rate and direction surface to be cleaned,Thereby can effectively blow afloat the dust on surface to be cleaned etc., by the relatively large air inlet of size 111 is set, can be byThe dust blowing afloat etc. sucks in dirt cup 2 as much as possible, have good cleaning effect, and cleaning efficiency is high.

As shown in Figure 1, dirt cup 2 is positioned at the front side of motor 3. Certainly, dirt cup 2 can also be positioned at the rear side (figure of motor 3Not shown), now motor 3 between air inlet 111 and dirt cup 2, thereby increased hand held cleaner 100Structure diversity. Be understandable that, the concrete setting position of dirt cup 2 and motor 3 can be according to actual requirement andAdaptive change, the present invention does not do concrete restriction to this.

In the time that hand held cleaner 100 cleans narrow and small structures in place such as such as keyboards, blow out from blowing mouth 121Air-flow can enter into the narrow and small gap on keyboard etc. and the dust at narrow and small gap place etc. is blown afloat, negative at motor cavity 31Under the effect of pressing, the dust blowing afloat etc. can be inhaled in housing 1 and be collected in dirt cup 2 by air inlet 111. ByThis, be very easy to the clean of the structure narrow and small to places such as such as keyboards, time saving and energy saving, and cleaning effect is good.

According to the hand held cleaner 100 of the embodiment of the present invention, by blowing mouth 121 being set and making blowing mouth 121 contiguousAir inlet 111, thus be very easy to clean to narrow and small gap place, and cleaning effect is good.

According to one embodiment of present invention, as shown in Figure 1, blowing mouth 121 tilts to prolong towards the direction of air inlet 111Stretch. Now the central axis of blowing mouth 121 is crossing with the central axis of air inlet 111, and intersection point is positioned at outside housing 1.Preferably, intersection point is for example positioned at, on surface to be cleaned (surface at the dust place on keyboard). Thus, air inlet111 can be drawn into the dust being blown afloat by blowing mouth 121 etc. in dirt cup 2 better, and pick-up performance is good.

According to one embodiment of present invention, housing 1 is provided with blast pipe 11, for example, with reference to Fig. 1, blast pipe 11Horizontal-extending, and one end of blast pipe 11 (for example, the left end in Fig. 1, i.e. free end) stretches out outside housing 1. ItsMiddle air inlet 111 is formed on the free end of blast pipe 11, and now air inlet 111 is positioned at the front side of blowing mouth 121.

Alternatively, the free-ended end face of blast pipe 11 along the flow direction of the air-flow of the blast pipe 11 of flowing through, towards away fromThe direction of blowing mouth 121 tilts to extend. For example, as shown in Figure 1, the left end end face of blast pipe 11 is from left to rightIn direction, be tilted to downward-extension. Thus, the air-flow blowing out from blowing mouth 121 can better blow to surface to be cleaned,And be difficult for directly getting back in dirt cup 2 by air inlet 111.

Further, the above-mentioned free-ended end face of blast pipe 11 is formed as tapered plane, thus, processes simple and costLow. Certainly, the above-mentioned free-ended end face of blast pipe 11 can also be formed as skew surface (scheming not shown), for example,Be formed as the oblique cambered surface recessed towards the direction at housing 1 center etc.

According to a specific embodiment of the present invention, in housing 1, be provided with blowing passage 12, one end (example of blowing passage 12As, the right-hand member in Fig. 1) be communicated with motor cavity 31 and the other end (for example, the left side in Fig. 1 of the passage 12 of dryingEnd) there is blowing mouth 121. Thus, the air-flow in motor cavity 31 can be delivered to blowing mouth by blowing passage 12121。

For example, as shown in Figure 1, blowing Channel 12-Bit is in the top of housing 1, and blowing passage 12 extends along fore-and-aft direction,Blowing passage 12 rear end be communicated with motor cavity 31, blowing mouth 121 be formed on dry passage 12 front end and be positioned at intoDirectly over air port 111, blowing passage 12 tilts to downward-extension in direction from back to front, now along flowing through blowingDistance between air flow direction, blowing passage 12 and the air inlet 111 of passage 12 reduces gradually, makes from blowing mouth121 air-flows that blow out can blow to the to be cleaned surface relative with air inlet 111, thereby blow afloat from surface to be cleanedDusts etc. can be inhaled in dirt cup 2 by air inlet 111 well.

Alternatively, blowing passage 12 extends along fore-and-aft direction straight line, as shown in Figure 1, thus, the gas in motor cavity 31Stream can flow to blowing mouth 121 better by linear blowing passage 12, thereby can blow afloat better to be cleanedLip-deep dust etc. Certainly, blowing passage 12 can also for example, along fore-and-aft direction curve (, wave or camber line etc.)Extend.

Further, blowing passage 12 preferably reduces gradually along its flow direction, the cross-sectional area of air-flow of flowing through, as Fig. 8Shown in Figure 10, thus, in the time of airflow passes blowing mouth 121, flow velocity is improved, thereby air-flow can be with higherFlow rate and direction surface to be cleaned, thereby can effectively blow afloat the dust on surface to be cleaned etc.

Be understandable that, the concrete setting position, shape, size etc. of blowing passage 12 can be according to actual requirement andConcrete setting, to meet better actual requirement.

Alternatively, between each pipeline of hand held cleaner 100, connect by ultrasonic bonding. Wherein, " each pipeline "Each independent tubes of refer on the flow direction of air-flow, air-flow passing through. For example, blast pipe 11 and dirt cup 2Connected mode between the inlet channel 211 of the first cyclone is ultrasonic bonding. Thus, by adopting supersonic weldingThe mode connecing, speed of welding is fast, and weld strength is high, and good airproof performance.

According to one embodiment of present invention, on housing 1, be formed with air outlet 311. For example, in the example of Fig. 1, go outAir port 311 is positioned at the side away from air inlet 111 of motor 3, and air outlet 311 is communicated with motor cavity 31, thereby byThe dust-contained airflow that air inlet 111 enters is after the dirt cup 2 of flowing through filters, and clean air-flow can pass through motor cavity 31And discharge from air outlet 311.

After the airflow passes dirt cup 2 that entered by air inlet 111, motor 3, from air outlet 311 and blowing mouth 121At least one outflow. That is to say that the air-flow entering from air inlet 111 can only flow out from air outlet 311, alsoCan only flow out from blowing mouth 121, can also flow out from air outlet 311 and blowing mouth 121 simultaneously. For example,, by enteringAfter the airflow passes dirt cup 2 that air port 111 enters and motor 3, can be by switching mechanism 4 switchably from air outlet311 and blowing mouth 121 at least one outflow.

For example, in the time that hand held cleaner 100 is normally worked (place such as sheet, curtain etc. that clean space is larger),Without lip-deep dust to be cleaned etc. being blown afloat by blowing mouth 121, now blowing mouth 121 can be closed,Under the effect of the negative pressure of motor 3, the dust on the surface to be cleaned being sucked by air inlet 111 etc. after dirt cup 2 filters,Dusts etc. are collected in dirt cup 2, and clean air-flow can be discharged by air outlet 311 through motor cavity 31.

In the time of the local narrow and small structure such as clean such as keyboards of hand held cleaner 100, can make blowing mouth 121 and motorChamber 31 is communicated with, thereby the air-flow blowing out from blowing mouth 121 can blow to the narrow and small gap of keyboard etc. and by the ash at this placeDirt etc. blow afloat, and under the effect of motor 3 negative pressure, the dust blowing afloat etc. can be inhaled into dirt cup 2 by air inlet 111In, the dust-contained airflow of 2 pairs of suctions of dirt cup filters, and the dust filtering out etc. is collected in dirt cup 2, and cleanAir-flow flow to blowing mouth 121 to continue to blow afloat the dust on keyboard etc. through motor cavity 31. Now can be by air outlet311 sealings completely, certainly, also can open a little air outlet 311, but should ensure that most of air-flow blows to blowing mouth 121.

According to one embodiment of present invention, blowing mouth 121 can be connected to break-make with motor cavity 31. When blowing mouth 121While connection with motor cavity 31, the air-flow in motor cavity 31 can flow to blowing mouth 121. When blowing mouth 121 and motor cavityWhen 31 partition, the air-flow in motor cavity 31 can not flow to blowing mouth 121.

For example, blowing mouth 121 can be connected to break-make by switching mechanism 4 with motor cavity 31, switching mechanism 4 quiltsBe configured to the conduction position of conducting blowing mouth 121 and motor cavity 31 and cut off blowing mouth 121 and motor cavity 31 everyMovable between disconnected position. In the time that switching mechanism 4 is positioned at conduction position, blowing mouth 121 is communicated with motor cavity 31, cleanClean air-flow can blow to surface to be cleaned by blowing mouth 121, and now hand held cleaner 100 can be to keyboard etc.Local narrow and small structure cleans. Cut off when position when switching mechanism 4 is positioned at, blowing mouth 121 and motor cavity 31 everyDisconnected, the air-flow in motor cavity 31 can not blow out by blowing mouth 121.

Further, in the time that switching mechanism 4 is positioned at conduction position, switching mechanism 4 seals or semiclosed air outlet 311.Switching mechanism 4 seals air outlet 311, and switching mechanism 4 seals air outlet 311 completely, the air-flow in motor cavity 31Can not flow out by air outlet 311; The semiclosed air outlet 311 of switching mechanism 4, i.e. part air-flow in motor cavity 31Can flow out by air outlet 311. Here, it should be noted that, " semiclosed " can be understood as switching mechanism 4A part for sealing air outlet 311; Or switching mechanism 4 and air outlet 311 at least partly between close together,Now the most of air-flow in motor cavity 31 blows out from blowing mouth 121, and only fraction air-flow flows out from air outlet 311.In the time that switching mechanism 4 is positioned at partition position, air outlet 311 is communicated with motor cavity 31, thereby when hand held cleaner 100When normal work, can treat constantly clean surface cleans.

Particularly, as shown in Figure 1-Figure 3, switching mechanism 4 comprises push pedal 41, and push pedal 41 is located at housing movablyOn 1, be formed with connected entrance 411 in push pedal 41, in the time that switching mechanism 4 is positioned at conduction position, connected entrance 411 will be driedMouth 121 and motor cavity 31 are communicated with.

For example, with reference to Fig. 1 and in conjunction with Fig. 2 and Fig. 3, push pedal 41 can be extended along fore-and-aft direction, for example, and push pedal 41Along fore-and-aft direction horizontal-extending, thereby push pedal 41 can move horizontally on fore-and-aft direction. Open the rear end of blowing passage 12Mouth is relative up and down for the opening being communicated with blowing passage 12 with on motor cavity 31, and now push pedal 41 is positioned at blowing passageBetween 12 open rearward end and the above-mentioned opening of motor cavity 31. In the time of hand held cleaner 100 normal work, switching machineStructure 4 is positioned at and cuts off position, and connected entrance 411 staggers with blowing mouth 121 and motor cavity 31, and motor cavity is sealed in push pedal 4131 above-mentioned opening, push pedal 41 separates blowing mouth 121 and motor cavity 31, thus the air-flow in motor cavity 31 can notBlow out (as shown in Figure 2) by blowing mouth 121. In the time need to cleaning the narrow and small structure in the places such as keyboard,Can mobile push pedal 41, make on connected entrance 411, the blowing open rearward end of passage 12 and the above-mentioned opening of motor cavity 31Lower relatively, thereby the air-flow in motor cavity 31 can enter into blowing passage 12 and by blowing mouth by connected entrance 411121 blow out.

Air outlet 311 is formed on motor cavity 31 and is positioned at the below of push pedal 41. As shown in Figures 2 and 3, push pedal41 are provided with closure plate 42, and closure plate 42 is extended straight down from the lower surface of push pedal 41, closure plate 42 and air-outMouth 311 is relative, and in the time that switching mechanism 4 is positioned at conduction position, closure plate 42 is sealed or semiclosed air outlet 311. Enter oneStep ground, in the time of closure plate 42 semiclosed air outlet 311, between closure plate 42 and air outlet 311, have gap orClosure plate 42 is sealed a part for air outlet 311. Thus, in ensureing blowing effect, reduced closure plate 42The accuracy of manufacture, saved cost. Alternatively, that closure plate 42 is configured to is bottom-up, thickness increases gradually, hasEnsure to effect the structural strength of closure plate 42.

Further, switching mechanism 4 further comprises: return unit 43, return unit 43 is located at housing 1 and push pedal 41Between, return unit 43 is normal promotion push pedal 41 in the direction towards cutting off position. Alternatively, return unit 43 is spring.For example, as shown in Figures 2 and 3, spring is located between motor 3 and closure plate 42 and is positioned at the front side of closure plate 42,Spring often promotes closure plate 42 backward, so that push pedal 41 often remains on the partition that cuts off blowing mouth 121 and motor cavity 31Position. Be that hand held cleaner 100 is often in normal operating conditions.

For push pedal 41 can be moved reposefully on fore-and-aft direction, can in motor 3 and closure plate 42, establish respectivelyPut locating dowel 421, the two ends of spring can be set in respectively in corresponding locating dowel 421. Alternatively, locating dowel 421Free end be formed as truncated cone-shaped, taper or hemispherical etc., to facilitate the installation of spring.

As shown in Figure 1-Figure 3, push pedal 41 is provided with push button 44, and push button 44 is located on the upper surface of push pedal 41, push button44 expose the upper surface of housing 1. Thus, user can realize push pedal 41 at conduction position by promoting push button 44And cut off the movement between position. Alternatively, push button 44 is hollow structure, to save material, reduces costs.

Hand held cleaner 100 is under normal conditions in the partition position shown in Fig. 2, and now push pedal 41 is by blowing mouth 121Separate with motor cavity 31, and closure plate 42 opens air outlet 311, push pedal 41 makes its guarantor under the elastic force effect of springBe held in this position. In the time need to cleaning the narrow and small structure in the places such as keyboard, can stir forward push button 44, makePush pedal 41 moves forward, and in the time promoting push pedal 41 to conduction position, connected entrance 411 is by motor cavity 31 and blowing passage12 are communicated with, and closure plate 42 moves forward to air outlet 311 and have certain interval, thus large in motor cavity 31Part air-flow can be blown out by blowing mouth 121 by blowing passage 12, can carry out clearly narrow and small gap well like thisClean, fraction air-flow is flowed out by the gap between air outlet 311 and closure plate 42 by air outlet 311, as figureShown in 3.

Thus, by switching mechanism 4 is set, in the situation that ensureing hand held cleaner 100 normal use, can be rightThe air-flow of discharging from air outlet 311 effectively utilizes, and has further strengthened the clean effect of hand held cleaner 100Really.

Thus, by adopting Cyclone Separation Technology to carry out purification separation to the dust-contained airflow entering in dirt cup 2, and canEffectively ensure that air-flow is in the interior mobile smoothness of dirt cup 2, and, by the first cyclone, filtration members and multiple are setThe second cyclone 22, adopts the first cyclone and multiple the second cyclone 22 to carry out secondary cyclonic separation, the first cycloneBulky grain in air-flow or dirt first can be filtered out with filtration members, and multiple the second cyclone 22 can be by elementary cleanMost of granule (for example dust granule) in air-flow after change is isolated, and last small part fine dust canFilter dirt gas good separating effect by egress filtering part.

Filtration members from the first cyclonic separation space A to the process of the second cyclonic separation space B, air-flow is purified.Wherein, filtration members is preferably removably located at the outer circumferential side of whirlwind assembly, thereby filtration members in use for some time canWith dismounting so that clean.

By at the interior guide duct 221 that arranges of the second cyclone 22, while having extended the stop of air-flow in the second cyclone 22Between, thereby can clean the air-flow to be cleaned entering in it better.

Alternatively, as shown in Figure 5 and Figure 6, guide duct 221 is with respect to the second cyclone 22 eccentric settings. NamelySay, the central axis of center axis deviation second cyclone 22 of guide duct 221, the central axis of guide duct 221 withThe central axis of the second cyclone 22 does not overlap. Be the periphery wall of guide duct 221 and the internal perisporium of the second cyclone 22A part between distance have and closely have far, make the air-flow after primary separation can be by bleed breach 222 firstTangentially enter a side distant between the periphery wall of guide duct 221 and the internal perisporium of the second cyclone 22, again aroundGuide duct 221 rotation is to a nearer side, can effectively ensure like this to enter into air-flow in the second cyclone 22 along withOne direction (for example, the counter clockwise direction in Fig. 6) rotation purification separation.

For example, as shown in Figure 5 and Figure 6, guide duct 221 is pipe, and guide duct 221 vertically extends, wind-guidingPipe 221 is positioned at the top of the second cyclone 22, and the upper end of guide duct 221 is connected also with the roof of the second cyclone 22There is wind-guiding outlet 2212 and lower end and there is wind guiding inlet 2211. Bleed breach 222 is positioned at the second cyclone 22Top. Enter air-flow in the second cyclone 22 start rotation around the upper end of guide duct 221 and move downward gradually (asShown in Fig. 5), form rotation down draft, rotation down draft becomes rising while dropping to the lower end of guide duct 221Air-flow, the dust in air-flow departs from air-flow and lands downwards, and cleaner air-flow enters in guide duct 221 and by leadingThe wind-guiding outlet 2212 of airduct 221 upper ends is discharged.

Further, as shown in Figure 6, be provided with dividing plate 227 in guide duct 221, dividing plate 227 is by guide duct 221 insideBe separated into two chambers. Thus, by dividing plate 227 is set, can be to entering into the ash of the air-flow in guide duct 221Dirt etc. further separate. Alternatively, dividing plate 227 vertically or is obliquely located in guide duct 221.

Air-flow is preferably identical with its direction of rotation in the second cyclone 22 in the direction of rotation of the periphery of whirlwind assembly.As shown in Figure 6, air-flow the direction of rotation of the periphery of whirlwind assembly is follow-up with it enter the second cyclone 22 after secondDirection of rotation in cyclone 22 is counterclockwise. Thus, can prevent the air turbulence in dirt cup 2, ensureDirt cup 2 has good separating effect.

With reference to Fig. 6, filtration members arranges around whirlwind assembly, is formed with and dodges mouth in filtration members, dodges mouth and guiding channel23 is relative. Thus, the air-flow of the guiding channel 23 of flowing through can directly flow to the periphery of whirlwind assembly by dodging mouth, andBefore flowing into the second cyclone 22, need to first pass through filtration members, thereby in ensureing filter effect, also protectDemonstrate,prove the smoothness of air current flow. For example, filtration members can be roughly " C " shape.

Certainly, filtration members can also be multiple, and multiple filtration members correspond respectively to the bleed breach 222 of multiple the second cyclones 22Arrange. Each filtration members all arranges with respect to one or more bleed breach 222, like this in the first cyclonic separation space AAir-flow after preliminary purification is directly tangentially entered in the second cyclone 22 and is carried out by bleed breach 222 later from filtration members warpSeparate, thereby before again separating, first carried out the filtration of bulky grain thing in the second cyclone 22, further improvedPurification separation effect.

Alternatively, above-mentioned filtration members can be screen pack (scheming not shown). Certainly, filtration members can also be with mistakeThe inserted sheet of filter opening. The mesh of screen pack or filtering holes can be the distribution of multilayer annular or the form with multiple lines and multiple rowsBe uniformly distributed, so that uniform filtering. In addition, the mesh of screen pack or the size range of filtering holes do not limit, size phaseTo less, good filtration effect, slightly greatly ventilation efficiency is high for size, and motor 3 energy losses are little, in practical application,Can select suitable size according to the performance requirement of product.

As shown in Figure 6, a side of the bleed breach 222 of each the second cyclone 22 is connected with and the second cyclone 22Connecting wall 224 and opposite side that sidewall is tangent extend outward extension 225, extension 225 and connecting wall 224 itBetween limit tangential tap air channel 226. Alternatively, the connecting wall 224 on multiple the second cyclones 22 extends and is tangentBe connected on the sidewall of the second cyclone 22 being adjacent, wherein extension 225 is along the gas of the tap air channel 226 of flowing throughThe flow direction of stream, extend towards the direction of corresponding connecting wall 224, now tap air channel 226 is configured to draw along flowing throughThe flow direction, the width of the air-flow of gas passage 226 reduce gradually. Thus, make the air-flow of whirlwind assembly periphery can be by drawingGas passage 226 carries out cyclonic separation, separating effect along second cyclone 22 that tangentially enters more swimmingly of the second cyclone 22Better.

As shown in Fig. 5 and Fig. 7, the inwall of one end with gas outlet 2112 of inlet channel 211 has and is suitable for enteringThe spigot surface of the air-flow guiding guiding channel 23 in gas passage 211. Thus, the flow through air-flow of inlet channel 211 is passableGuiding channel 23 leads better under the effect of spigot surface. For example, with reference to Fig. 5 and Fig. 7, inlet channel 211 byAir inlet pipe 21 limits, and the air inlet 2111 of inlet channel 211 and gas outlet 2112 are respectively by under air inlet pipe 21End and upper end limit, and air inlet pipe 21 comprises horizontal pipeline section connected with each other and vertical pipeline section, the free end of horizontal pipeline section(for example, the left end in Fig. 5) is communicated with air inlet 111, the vertically free end of pipeline section (for example, upper in Fig. 5End) be communicated with guiding channel 23, spigot surface is positioned at the free-ended roof of vertical pipeline section, and air-flow can in the time flowing through this placeTo lead better in guiding channel 23 under the effect of spigot surface. For example, spigot surface is preferably formed as arcwall face.

Alternatively, as shown in Figure 6, guiding channel 23 is configured to increase gradually along the flow direction of air-flow, width. Thus,Can lead better under the guide effect of guiding channel 23 periphery of whirlwind assembly of the air-flow of guiding channel 23 of flowing through.

Alternatively, the bottom of each the second cyclone 22 has opening 223, isolated little through the second cyclone 22The below that grain etc. can be fallen the second cyclone 22 by the opening 223 of the second cyclone 22 bottoms, has facilitated littleThe collection of grain etc., and when air-flow is at second 22 internal cyclones whens separation of cyclone isolated granule etc. of can not kicking up.

Wherein, between all parts in dirt cup 2, can connect by the mode of ultrasonic bonding.

Thus, by adopting above-mentioned dirt cup 2, strengthen the dirt gas separation function of dirt cup 2, made most of dust at streamBefore egress filtering part, be thrown off air-flow, only have minority dust to enter egress filtering part, therefore can effectively prevent outMouth filtration members is stopped up by a large amount of dusts, has reduced the cleaning frequency of egress filtering part, has increased the use of egress filtering partIn the life-span, the while has also reduced the burden of motor 3.
