By such configuration, can shorten the length of body, can reach small-sized light weight.And because the intake section of cyclone separating tube 104 there is no need to be arranged to bending etc., so can obtain the effect that reduces to lose.
Here, the direction that is flowed out from cyclone separating tube 104 by connected entrance 117 by the dust of above-mentioned cyclone separating tube 104 centrifugations is the direction of rotation in the cyclone separating tube 104, and is the tangential direction of cyclone separating tube 104.Therefore, in this example, can both be configured in front one side (flexible pipe is connected oral area 116 1 sides) of the 1st after-filter 106 body of dust collector 1 farthest of the switching in above-mentioned disposal box 105 with the upper opening 118 of the connected entrance 117 of cyclone separating tube 104 and the disposal box 105 that is communicated with this connected entrance 117.Here, dust by cyclone separating tube 104 centrifugations begins accumulation near the 1st after-filter 106 that opens and closes, pile up to upper opening 118 1 sides of the connected entrance 117 of cyclone separating tube 104 and the disposal box 105 that is connected with this connected entrance 117 successively, so before above-mentioned disposal box 105 was filled up by dust, dust was difficult to stop up above-mentioned connected entrance 117 and above-mentioned upper opening 118.That is, can effectively utilize the volume of above-mentioned disposal box 105.
Below with reference to Fig. 8 to Figure 14 cyclone separating tube 104 and disposal box 105 are described in detail.Fig. 8 is the outward appearance perspective view of cyclone separating tube 104, Fig. 9 is the outward appearance perspective view of disposal box 105, Figure 10 is the A-A cutaway view of Fig. 6, Figure 11 comprises the inlet tube part of cyclone separating tube 104 at interior cutaway view, Figure 12 comprises the connected entrance 117 of cyclone separating tube 104 and disposal box 105 at interior cutaway view, Figure 13 is the side view when exhaust one side is seen disposal box 105, and Figure 14 is the perspective view of inner core 131.
On the urceolus 135 of cyclone separating tube 104, be provided as the inlet tube 115 of the air intake of urceolus 135, air entered like that along the roughly tangential direction of cylindrical circular cyclone separating tube 104 roughly be provided with in the central lower of the central axis direction length of this cyclone separating tube 104.Central upper at cyclone separating tube 104 is provided with connected entrance 117, makes air in dust flows into disposal box 105.The bottom of cyclone separating tube 104 is provided with inner core 131, links to each other with the exhaust outlet 120 of bottom.Inner core 131 by tube portion 134, with helical form be wrapped in partition wall 132 in this one 134, the guiding wall 137 that connects inlet tube 115 and above-mentioned tube portion 134 constitutes.In tube portion 134, embed the shaping resin fleece integratedly as screen pack 133 with tube portion 134.Screen pack 133 both can be formed in the cylindrical portions may of side as shown in figure 10, also can constitute the last plane of a portion and the cylindrical portions may of side together.Here, around the cylindrical portions may of above-mentioned inner core 131 sides, all be not provided with above-mentioned screen pack 133, about about 90 degree above-mentioned screen pack 133 and peristome be not set near the above-mentioned inlet tube 115.Therefore,, also can directly directly not contact, prevented from effectively to puncture and the appearance of wrapping phenomena with above-mentioned screen pack 133 even flow into tiny dust such as hairs from above-mentioned inlet tube 115.Simultaneously, flowing under the situation of pointed dust such as pin from above-mentioned inlet tube 115, owing to directly do not contact with above-mentioned screen pack 133, thereby prevent that above-mentioned screen pack 133 from breaking and the outflow of dust.
And because screen pack 133 is subjected to the power in above-mentioned inner core 131, internal diameter one side that therefore is preferably in above-mentioned screen pack is provided with the rib 136 of inner core.Here,, then break away from easily, thereby be convenient to cleaning attached to the dust on the above-mentioned screen pack 133 if screen pack 133 is prevented charged processing.
And, because the urceolus 135 of cyclone separating tube 104 is provided with inlet tube 115 as the air intake of urceolus 135 in the central lower of the central axis direction length of this cyclone separating tube 104, therefore the flexible pipe connector 116 that is communicated with above-mentioned inlet tube 115 also can be configured in the central lower of the central axis direction length of cyclone separating tube 104.Therefore, because above-mentioned flexible pipe connects the bottom that oral area 116 can be configured in body of dust collector 1, so under the situation of using manual operation pipe 3 by above-mentioned flexible pipe 2 above-mentioned body of dust collector 1 to be retracted, above-mentioned body of dust collector 1 is difficult to overturning, can stably retract.
Owing to above-mentioned flexible pipe can be connected the downside that oral area 116 is configured in above-mentioned body of dust collector 1, so need not the above-mentioned flexible pipe connection of configuration oral area 116 on loam cake 102, when from above-mentioned body of dust collector 1, taking out disposal box 105, cyclone separating tube 104, even under the state that above-mentioned flexible pipe 2 is installed, also can easily open and close above-mentioned loam cake 102.
Here, rise in order to make the air flow top in the cyclone separating tube 104, the partition wall 132 of above-mentioned inner core 131 138 rises with helical form upward from the starting position rolled.Therefore, flow into dust in the cyclone separating tubes 104 when this helical form partition wall 132 rises, above-mentioned cyclone separating tube 104 in, rotate,, and be transported in the disposal box 105 by connected entrance 117, upper opening 118 by centrifugation from inlet tube 115.So, because making above-mentioned next door 132 rises upward with helical form, therefore dust is subjected to the very strong effect of rising in above-mentioned cyclone separating tube 104, even direct current wireless dust collectors etc. also can be transported to dust disposal box 105 with the dust catcher of the low air quantity work of per minute below 1 cubic metre.Here; because the direction of principal axis of cyclone separating tube 104 is not a horizontal direction; when above-mentioned low air quantity; the heavy dust that flows in the above-mentioned cyclone separating tube 104 can can't rotate in the process of rotating and fall; thereby avoided repeatedly colliding cyclone separating tube 104, can prevent the injury and the breakage of cyclone separating tube 104 effectively.
The height H of guiding wall 137 is bigger than the height L of inlet tube 115.Therefore, the air stream that flows and rotate in cyclone separating tube 104 from inlet tube 115 leaked-in airs is difficult to interfere and mixing, can enlarge the reduction loss in the confusion that prevents to bring thus when avoiding flowing into rapidly.And, if the section shape of inlet tube 115 adopts the words of the roughly rectangular shape of removing on every side four jiaos, at air stream when inlet tube 115 flow into cyclone separating tube 104, owing to can flow into along the wall of urceolus 135 and the partition wall 132 of inner core 131, therefore compare with the situation of the inlet tube 115 of circular section, can reduce and enlarge the flow loss that is caused when flowing into cyclone separating tube 104 rapidly.
As mentioned above, section shape at inlet tube 115 is under the roughly rectangular situation, make the section configuration of the connecting portion 2a of flexible pipe 2 transform to the promptly roughly rectangular shape of section shape of inlet tube 115 more lenitively by the circle of flexible pipe one side, that suppresses whereby to flow the loss that brings such as peels off, and air stream is flow in the cyclone separating tube 104.
During rubbish, hold the handle 123 on disposal box 105 tops in cleaning, lift disposal box 105, and press and block the bar 142 that the clamp portion of filter frame 140 becomes one, carry out after opening filter frame 140.The cleaning of the 1st after-filter 106 is carried out after the 1st after-filter 106 can being taken out from filter frame 140.
But the most handy sponge or the nonwoven of making by urethanes that can clean of the 1st after-filter 106 or can clean materials such as filter paper with foaminess sweeping compound.
If the 1st after-filter the 106, the 2nd after-filter 112 is implemented to prevent charged processing, then peel off easily attached to the dust on the 1st after-filter 106 and above-mentioned the 2nd after-filter 112, clean easily.
The bottom of disposal box 105 is provided with connecting path 145 and cyclonic separation portion flow export 146 integratedly.Therefore, though the whirlwind portion flow export 146 of this disposal box 105 and main tank 141, connecting path 145, filter frame 140 bottoms separates, both engaging portion are all with the airtight conditions butt.And, with the exhaust outlet 120 of cyclone separating tube 104 also with the airtight conditions butt.
When electric blower 107 starts, the body of dust collector 1 that constitutes like this sucks the inlet tube 115 of dust laden air from cyclone separating tube 104 in this cyclone separating tube 104 by its inspiratory force, and by in this cyclone separating tube 104, rotating with the dust centrifugation, and rise to the top of these cyclone separating tube 104 inside, be transported to disposal box 105 1 sides afterwards.Flow to exhaust outlet 120 by screen pack 133 from the inner core 131 of cyclone separating tube 104 through the air of dedusting.This screen pack 133 has the function that dust such as preventing fiber dust, paper passes.
The air that comes out from exhaust outlet 120 flows to the 2nd after-filter 112 by connecting path 145, cyclonic separation portion flow export 146.
The dust laden air that comes out from the connected entrance 117 of cyclone separating tube 104 flows into disposal boxes 105 by the upper opening 118 that is arranged on disposal box 105 tops, and airborne dust is deposited in the front of the 1st after-filter 106 by 106 interceptions of the 1st after-filter.Air flow the 2nd after-filter 112 1 sides by the 1st after-filter 106.
The dust removal performance of the 1st after-filter 106 preferably can have the ability that dust is separated to μ m level by the ability decision of its filtering material.But dust collection capacity is too high, also stops up too early easily, makes decision so preferably can take into account the dust collection capacity of comprehensive integral.
Because the dust that enters in the body of dust collector 1 almost accumulates in the disposal box 105 all, get final product so when cleaning rubbish, dedusting is carried out in disposal box 105 direct taking-up from body of dust collector 1.Cleaning rubbish is not preferably also carried out in long-pending full by dust fully at disposal box 105.Therefore, disposal box 105 is provided with cleaning rubbish line 155 as shown in Figure 9 on the position relative with upper opening 118, and the user can carry out the garbage-cleaning operation with reference to this line.Garbage-cleaning 155 lines promptly are not that horizontal line neither vertical line, because rubbish storage in disposal box 105 time, is buried by dust near the part of upper opening 118, at last so set certain inclination according to the situation of accumulating of dust.
In addition, because this example is divided into 2 routes with the air stream of body of dust collector 1 as shown in Figure 7, so the dust in the disposal box 105 is subjected to this action of pressure dust always to be in confined state along the flow direction generation pressure differential of air.Because many more these pressure differentials of dust of accumulating are big more, therefore also has the big more characteristic of the many more decrements of dust.Dust in the disposal box 105 are piled into stratiform in the front of the 1st after-filter 106, and together pile up with tiny dust.Therefore, owing to be mixed with dust between the fiber dust, can obtain the effect that dust is difficult to fly upward when cleaning rubbish.
Because the air air quantity of the exhaust outlet 120 by cyclone separator 104 is littler during by disposal box 105 than air, so can reduce the resistance of cyclone separator 104.Therefore, the feature that has the suction power that can improve dust catcher.
In addition, dust laden air in cyclone separating tube 104 flows in this cyclone separating tube 104 from the inlet tube 115 of cyclone separating tube 104, and the rotation by in this cyclone separating tube 104 is with the dust centrifugation, rise to the top of these cyclone separating tube 104 inside, be transported to disposal box 105 1 sides afterwards.At this moment, owing to there is the air stream of discharging by above-mentioned disposal box 105 from the 1st after-filter 106, therefore in above-mentioned cyclone separating tube 104, be easy to flow into above-mentioned disposal box 105 1 sides from above-mentioned cyclone separating tube 104 by the dust of centrifugation, because dust can be separated in the moment that flows into above-mentioned disposal box 105 1 sides, so can improve efficiency of seizing dust.
And, be difficult to adverse current to above-mentioned cyclone separating tube 104 owing in above-mentioned cyclone separating tube 104, be transported to the dust of above-mentioned disposal box 105 1 sides after by centrifugation, can not disperse once more so be transported to the dust of above-mentioned disposal box 105 1 sides, can improve efficiency of seizing dust.
And, dust attached to the situation on the screen pack 133 of inner core 131 under, because from reducing that exhaust outlet 120 is discharged, so increase by the air air quantity by the disposal box exhaust outlet 144 of the exhaust outlet of above-mentioned disposal box 105 of the 1st after-filter 106 by the air air quantity after cyclone separating tube 104 dedustings.Therefore, have attached to the dust on the above-mentioned screen pack 133 of above-mentioned inner core 131 and can be transported to feature in the disposal box 105.
And, make by the 1st after-filter 106, to discharge from the exhaust outlet of the gas of above-mentioned disposal box 105 be that the sectional area of the sectional area ratio of disposal box exhaust outlet 144 exhaust outlet 120 of discharging the air after the dedusting of cyclone separating tube 104 is big.Therefore, the sectional area of the 1st after-filter 106 can be increased, flow velocity can be reduced by the air of above-mentioned the 1st after-filter 106.Therefore, can reduce to dispel from the dust that above-mentioned the 1st after-filter 106 comes out.And, because the pressure loss can reduce air by above-mentioned the 1st after-filter 106 time, so have the feature that can further improve dust catcher suction power.
Here, the end of downstream side 119 rounded shapes of the connected entrance 117 by making cyclone separating tube 104 perhaps stick the better material of (low-friction coefficient) of slickness, can prevent that dust is stuck in above-mentioned downstream side end 119.In addition, under the situation of the 1st exhaust outlet 144 lopsidedness of the exhaust outlet of a side direction disposal box 105 above the above-mentioned end of downstream side 119 (under the situation that the peristome of connected entrance 117 is expanded upward), even end of downstream side 119 cards at connected entrance 117 have dust, dust also can be to the top of above-mentioned end of downstream side 119 side shifting, by in moving by the air stream effect of cyclone separating tube 104 to disposal box 105, dust is easy to be peeled from the downstream side end 119 of above-mentioned connected entrance 117.
Because along with the dust amount that accumulates in the disposal box 105 constantly increases, the resistance that runs into during by disposal box 105 also increases gradually, the flow in the disposal box can decrease.Therefore, when a lot of dust that easily produces smells was arranged, the amount of the air by disposal box can reduce, and can access the effect that smell is difficult to be diffused into the dust catcher outside.
In addition, even when the connecting path 145 of making dirty, whirlwind portion flow export 146, also can under the state that takes out disposal box 105, clean simply.
And, because the inlet tube 115 and the inner core 131 of cyclone separator 104 are located at the bottom, so the connected entrance 117 of cyclone separating tube 104 and the upper opening 118 of disposal box 105 can be set on top, can fall under the effect of gravity owing to enter the dust of disposal box 105, overflow to cyclone separating tube 104 so can prevent it.
And, because the upper opening 118 of disposal box 105 is configured in the place ahead of above-mentioned disposal box 105, so erect when taking at body of dust collector 1, because the upper opening 118 of above-mentioned disposal box 105 is configured in the top of above-mentioned disposal box 105, can prevent that therefore the dust that enters above-mentioned disposal box 105 from overflowing to above-mentioned cyclone separating tube 104.
Because disposal box 105 is configured in the side of cyclone separating tube 104, therefore need not improve the height of body of dust collector 1, the length of cyclone separating tube 104 that just can extend is so have the feature that can improve the rubbish separating power of being undertaken by the stream that circles round.
Under the situation that electric blower 107 stops, can stop up inlet tube 115, for above-mentioned inlet tube 115 and above-mentioned cyclone separating tube 104 are communicated with, can be near the valve that guiding wall 137 1 sideway swivels of the inner core 131 of configuration in above-mentioned cyclone separating tube 104 are set the inlet tube 115.In this case, when cyclone separating tube 104 is taken out in the running that stops electric blower 107, can prevent overflowing of dust.
It is also passable as shown in figure 15 cyclone separating tube 104 and disposal box 105 to be set to one, in this case, though weight portable during cleaning rubbish strengthens, operating characteristics is low, but because of between cyclone separating tube 104 and the disposal box 105, constitute one between exhaust outlet 120 and the connecting path 145, can keep air-tightness completely, increase so the loss that brings such as can suppress to leak, not only can further improve dust suction power, the while can also be suppressed the leakage of dust and be overflowed.
Though also can constitute connecting path 120, connecting path 145 and connectors 146, when the connecting path internal contamination, can not clean simply, but can reduce the bubble-tight part of total maintenance with other members that connect with nowel 101.And can be with keeping airtight direction to be decided to be above-below direction, so have the bubble-tight feature of easy maintenance.
Though above narration is with the situation of cyclone separating tube 104 as the separation chamber of dirt separation from dust laden air, but above-mentioned separation chamber is not limited to cyclone separating tube 104, if adopt in the bottom of this separation chamber the inlet portion that dust laden air is flowed into be set, top in this separation chamber is provided with the connected entrance that is communicated to the disposal box that is positioned at the side, separation chamber, be provided with formation in the inside of this separation chamber and transport the such electric dust collector of guided plate of the air-flow of air and dust from the bottom to top, then the flexible pipe connector that is communicated with above-mentioned inlet portion also can be configured in the central lower of the short transverse of above-mentioned separation chamber.Therefore, because above-mentioned flexible pipe connects the bottom that oral area is configured in body of dust collector, therefore under the situation of using the manual operation pipe by above-mentioned flexible pipe above-mentioned body of dust collector to be retracted, above-mentioned body of dust collector is difficult to overturning, can stably retract.
With reference to the accompanying drawings the 2nd example of the present invention is described below.Figure 16 is the outward appearance perspective view of the vertical electric dust collector of an expression example of the present invention.Figure 17 is the side view of dust catcher shown in Figure 16.Here, for flowing of explanation air, the part is represented with section.The longitudinal section of the dust collecting part 460 that Figure 18 is combined as a whole for cyclone separating tube 404 and disposal box 405.This figure is the longitudinal section from the rear side of body of dust collector 301.Figure 19 is the figure from the rear side dust collecting part 460 of body of dust collector 301.Figure 20 is the cutaway view of the B-B section of expression Figure 19.
Suction inlet 305 to the floor opening is installed on the body of dust collector 301, can in predetermined angular range, rotates, in this suction inlet 305, be provided with rotating brush 306 towards ground.In this body of dust collector 301, dust collecting part 460 can be installed with freely loading and unloading.Dust collecting part 460 comprises cyclone separating tube 404, be configured in the disposal box 405 on these cyclone separating tube 404 next doors, be positioned at the filter frame 440 of body of dust collector 301 1 sides of above-mentioned dust collecting part 460, and this filter frame 440 can freely rotate.For the rotation of the rotating shaft by the electric blower (not shown) drives the rotating brush 306 in the suction inlet 305 and the air blast of electric blower, this electric blower is configured in the below of above-mentioned dust collecting part 460 of bottom of top, the body of dust collector 301 of above-mentioned suction inlet 305.By the inspiratory force of this electric blower, undertaken air-breathingly by above-mentioned suction inlet 305, suck the dust sneak into this inspiratory flow, the dust laden air of suction by scalable tube connector 304 and flexible pipe 302 controls of dust at the disposal box 405 that is arranged in cyclone separating tube 404 1 sides.In addition, be provided with the handle part 303 that the user controls on the top of body of dust collector 301, the operation by handle part 303 can move forward and backward dust catcher.
This body of dust collector 301 flow into dust laden air the cyclone separating tube 404 and makes its rotation from inlet tube 415 by flexible pipe 302, dust is separated, and connected entrance 417, the upper opening 418 of dust by top is transported in the disposal box 405.The exhaust of coming out from cyclone separating tube 404 is discharged to by the exhaust outlet 420 that is arranged on cyclone separating tube 404 bottoms in the connecting path 445 of disposal box 405 bottoms setting by inner core 431.In addition, portion of air flows into disposal box 405, catches dust by the 1st after-filter 406.The exhaust of disposal box 405 is via the 1st after-filter 406, discharges from disposal box exhaust outlet 444, and sucked by electric blower by the 2nd after-filter 412.Also from above-mentioned exhaust outlet 420 pass through connecting path 445 outflows above-mentioned whirlwind portion flow export 446 from the exhaust that cyclone separating tube 404 comes out this moment, together sucked by electric blower by the exhaust of above-mentioned the 2nd after-filter 412 with above-mentioned disposal box 405.From then on the electric blower exhaust of coming out is discharged into outside the machine by exhaust outlet 307 by behind the filter.
Make the inlet tube 415 of cyclone separating tube 404 be connected oral area 416 with flexible pipe and carry out butt with airtight conditions, cyclone separating tube 404 and inner core 431 carry out butt by elastomer air packing 451 with airtight conditions, the exhaust outlet 420 and the connecting path 445 of cyclone separating tube 404 bottoms carry out butt by elastomer air packing 452 with airtight conditions, whirlwind portion flow export 446 and disposal box exhaust outlet 444, and hold and carry out butt with airtight conditions between the body of dust collector 301 of the 2nd after-filter 412 and energize in this wise.Filter frame 440 is equipped with elastomer air packing 450 at disposal box 405 and connecting path 445 1 sides, body of dust collector 301 1 sides.Therefore, when being installed to dust collecting part 460 on the body of dust collector 301, making this dust collecting part 460 and body of dust collector 301 carry out butt and energize in this wise and install with airtight conditions.Here, because the turnover of the air between above-mentioned body of dust collector 301 and the above-mentioned dust collecting part 460 is the fore-and-aft direction at above-mentioned body of dust collector 301, can bring into play this airtight conditions so apply power, have and obtain bubble-tight feature easily by fore-and-aft direction at body of dust collector 301.When being pressed into dust collecting part 460 in the body of dust collector 301, by the kayser 461 that is arranged on the body of dust collector 301 dust collecting part 460 is fixed on the body of dust collector 301, realize airtight conditions, can suppress the leakage of dust and overflow.
In addition, the direction of principal axis of cyclone separating tube 404 is not a vertical direction and be partial to incline direction, need not strengthen the short transverse of dust catcher 301, and the axial length of the cyclone separating tube 404 that just can extend improves and catches the dirt performance.
Hold handle 423, press and unload switch 462, cyclone separating tube 404 just can separate taking-up with disposal box 405 from body of dust collector 301.Exhaust one side at disposal box 405 is provided with the 1st after-filter 406 and filter frame 440.
If filter 406b such as the sponge dust amount of collected is a lot of at the upstream side of the 1st after-filter 406 are configured in the Rose Box 406a, can prevent to dispel from the dust that the 1st after-filter 406 comes out.At this moment, if filter 406b is made by the material of ether system etc., material capable of washing then helps operation.And, if be configured as one and pass through the screen pack 406c that prevents charged processing in one side setting of the upstream of this filter 406b and Rose Box 406a embedding, then when cleaning rubbish, owing to increased the fissility of the dust that comes out from the 1st after-filter, so it is rubbish peels off easily, more satisfactory.In addition, if the 1st after-filter 406 is provided with filters such as using nonwoven, screen pack, can prevent the leakage of the dust of disposal box 405 better.The 1st after-filter 406 of formation such as nonwoven embeds with filter frame 440 and forms as one thus, makes operation become light.
If the 2nd after-filter 412 uses the nonwoven of accordion etc., the air that can increase filter so can reduce aeration resistance, improves suction power by area greatly.And, can improve the efficient of catching dust owing to reduced the flow velocity of air when passing through filter.
If the 2nd after-filter 412 is divided into whirlwind portion flow export 446 sides and disposal box exhaust outlet 444 sides, and the words of the height of the fold of the filter of increase whirlwind portion flow export 446 sides, flow velocity in the time of can further reducing the exhaust of coming out from cyclone separating tube 404 by the 2nd after-filter 412, and reduce aeration resistance, can catch the dust of failing to separate seizure in the cyclone separating tube 404 effectively simultaneously.
Flexible pipe connector 416 is seen the central authorities of the width that is positioned at body of dust collector 301 from the top, and is configured in the back side of above-mentioned body 301.The central shaft of cyclone separating tube 104 is positioned on the position of staggering from the central authorities of above-mentioned body of dust collector 301 widths, and the inlet tube 415 that air is flowed into along the roughly tangential direction of cyclone separating tube 404 is configured in the end of dust collecting part 460.That is, when being installed to this dust collecting part 460 on the body of dust collector 301, dust laden air in inlet tube 415 from the back side of body of dust collector 301 and by the distolateral inflow of left and right directions.In addition, disposal box 405 is configured in a width side opposite with respect to the central shaft of above-mentioned body of dust collector 301 and above-mentioned cyclone separating tube 404, the side of cyclone separating tube 404.And,, constitute the stream that is communicated with the body of dust collector rear side from dust collecting part 460 exhaust of coming out and the air that passes through the 1st after-filter 406 with from the air interflow that whirlwind portion flow export 446 flows out.By such configuration, can shorten the length of body, reached the purpose of small-sized light weight.
Be seen as on the position in left side of central shaft of left and right directions of body of dust collector 301 if cyclone separating tube 404 is configured in from the front, dispose the inflow side of the 1st after-filter the 406, the 2nd after-filter 412 and electric blower on the right side, then owing to the air flow circuit that has shortened from the 2nd after-filter 412 to electric blower, so can reduce the loss that friction brings.At this moment, the synchronous belt that is used for the rotating brush 306 of drive arrangements in suction inlet 305 preferably is configured in the i.e. left side of above-mentioned cyclone separating tube 404 1 sides.In addition, these are configured in right-hand side assembly and can obtain same effect with the parts symmetry replacement that is configured in the left side.
The direction that the dust of above-mentioned cyclone separating tube 404 centrifugations flows out from cyclone separating tube 404 by connected entrance 417 is the direction of rotation in cyclone separating tube 404, and is the tangential direction of cyclone separating tube 404.Therefore, the upper opening 418 of this example disposal box 405 that can be communicated with the connected entrance 417 of cyclone separating tube 404 and with this connected entrance 417 both be configured in front one side (being connected the opposite side of oral area 416 with flexible pipe) of the 1st after-filter 406 body of dust collector 301 farthest of switching from above-mentioned disposal box 405 in.This wherein, the dust of cyclone separating tube 404 centrifugations begins accumulation near the 1st after-filter 406 that opens and closes, afterwards dust while being compressed the connected entrance 417 from cyclone separating tube 404 pile up in turn to upper opening 418 1 sides of the disposal box 405 that is communicated with this connected entrance 417, so before above-mentioned disposal box 405 is filled up by dust, dust is difficult to stop up above-mentioned connected entrance 417 and above-mentioned upper opening 418, can accumulate more dust.That is to say, can effectively utilize the volume of above-mentioned disposal box 405.
In addition, because the 1st after-filter 406 is installed in the place of close body of dust collector 301 rear side in the dust collecting part 460, so can make the filter area of the 1st after-filter 406 bigger than the area of the bottom that is located at above-mentioned dust collecting part 460, therefore can reduce the aeration resistance of above-mentioned dust collecting part 460, can reduce the loss.
This formation can be accumulated more dust in disposal box 405, so can prolong the cycle of garbage-cleaning.And owing to be mingled with tiny dust such as native sand in the fiber dust in the dust and be compressed, so have the feature that tiny dust is difficult to disperse when cleaning rubbish.
When being installed to dust collecting part 460 on the body of dust collector 301, because the upper opening 418 of connected entrance 417 and disposal box 405 can be configured in front one side of above-mentioned body of dust collector 301, so can near the position the upper opening 418, represent garbage-cleaning line 455.Therefore, the user can reference configuration carry out the garbage-cleaning operation at the garbage-cleaning line 455 of above-mentioned body of dust collector 301 fronts of the position of seeing easily one side.Because when in disposal box 405, accumulating dust, buried by dust at last, so garbage-cleaning line 455 is set certain inclination according to the situation of accumulating of dust near the part of upper opening 418.
When cleaning rubbish, hold the handle 423 of dust collecting part 460, press and unload switch 462, above-mentioned dust collecting part 460 is separated taking-up from body of dust collector 301.Next, the bar 442 that becomes one by the clamp portion of pressing and block filter frame 440 as rotating shaft, is opened the switch shaft 443 of filter frame 440 and is operated with above-mentioned filter frame 440.The cleaning of the 1st after-filter 406 can be cleaned the 1st after-filter 406 and be carried out.At this moment, because disposal box 405 is expanded from the one side direction back side, front, one side (filter frame 440 sides) of body of dust collector 301, so clear up the dust that accumulates in the above-mentioned disposal box 405 easily, above-mentioned dust is difficult to remain in the above-mentioned disposal box 405.
When the filter class takes place to stop up, the 1st after-filter 406 waters are cleaned, re-use after the air dry.In addition, the 2nd after-filter 412 also takes out, and water cleans, and installs after the air dry again.
From the urceolus 435 of cyclone separating tube 404, unload above-mentioned inner core 431 down clean inner core 431 screen pack 433, again screen pack 433 is installed on the inner core 431 after the cleaning.So,, dust is arranged,, just can easily remove dust from the urceolus 435 of cyclone separating tube 404 as long as above-mentioned inner core 431 is unloaded though in cyclone separating tube 404, all accumulate having sucked excess amount of dust when its disposal box 405 all will be overflowed.
And because screen pack 433 is subjected to the pressure in above-mentioned inner core 431, internal diameter one side that therefore is preferably in above-mentioned screen pack is provided with the rib 436 of inner core.If screen pack 433 is prevented charged processing, break away from easily attached to the dust on the above-mentioned screen pack 433, thereby be convenient to cleaning.
