The specific embodiment
Below by Fig. 1～10 electric dust collector among the 1st embodiment of the present invention is described.
In Fig. 1～Figure 10,4 is the dust collector host body, and 5 is dust-collection element.Dust-collection element 5 comprises that centrifugal separation unit 7 and dust stockpile unit 8.Centrifugal separation unit 7 is with the electric fan 6 that produces dust-absorbing airflow and attract the suction nozzle (not shown) of dust to be connected, and is arranged on body upper, is used for centrifugation dust being separated from the dust-absorbing airflow that sucks.Dust stockpiles unit 8 and is arranged on underpart, is used to stockpile the dust of separating from centrifugal separation unit 7.In dust-collection element 5, the central shaft of the vertical direction of centrifugal separation unit 7 is 30 ° of inclinations with respect to the central shaft that dust stockpiles the vertical direction of unit 8.
In addition, reference number 9 is for being used for making the air entry that flows into dust-collection element 5 from suction nozzle dust-absorbing airflow that suck, that contain dust, 10 in the porch of centrifugal separation unit 7 will from air entry 9 dust-absorbing airflow approximate equalities that suck, that contain dust be diverted to diffluence pass a plurality of centrifugal separation units 7.In addition, 11 for being used for carrying the handle portion of dust-collection element 5; 12 for covering the dust-collection element lid that is located at the peristome 13 that roughly is located at the top in the dust-collection element 5 and is provided with the filter unit 14 that dust contained in the dust-absorbing airflow that will absorb filtered; 15 for be located near the handle portion 11, be used to make between dust-collection element lid 12 and the dust-collection element 5 and fix or remove fixing functional unit, functional unit 15 can smoothly just can be operated when holding handle portion 11.
In addition, 16 is fore filter, and such fore filter is configured between dust-collection element 5 and the dust-collection element lid 12, roughly is on the central shaft of vertical direction of centrifugal separation unit 7, slightly cylindrical, is used to stockpile thick dust.17 for being located at the guard block of fore filter 16 belows, roughly in the form of annular discs.
In addition, 18 for being located at the outlet that dust stockpiles on the periphery wall of unit 8, is used to discharge dust; 19 for covering the discharge flap of outlet 18.Discharge flap 19 and be installed near the turning cylinder 20 of outlet 18, be provided with near the turning cylinder 20 when rotation and will discharge flap 19 securing fixed parts 21 with the form that can freely rotate.
The operational circumstances and the effect of above-mentioned dust catcher are described below.
As shown in Fig. 1, Fig. 2, when electric dust collector is worked, the dust-absorbing airflow that contains dust that is sucked by electric fan 6 passes air entry 9, shunt by diffluence pass 10 approximate equalities of the air-breathing upstream side that is located at centrifugal separation unit 7 ground, and under such state, roughly attracted by tangential direction towards the inner surface of centrifugal separation unit 7.
Contain be inhaled into dust dust-absorbing airflow on one side around the internal perisporium face rotation of centrifugal separation unit 7, on one side fall downwards in self mass action, the dust that stockpiles below being located at centrifugal separation unit 7 stockpiles in the unit 8.Afterwards, the swirling eddy in the centrifugal separation unit 7 rises after stockpiling at dust and reflecting on the bottom surface of unit 8 once more, and the dust that stockpiles for the moment also will be rolled once more upward.But, be located at fore filter 16 bottoms, downwards open and the effect of the discoid guard block 17 that appearance and size is bigger than the appearance and size of fore filter 16 under, dust is returned bounce-back again, stockpiles once more in dust stockpiles unit 8.By repeating such operation, dust just will stockpile in dust stockpiles unit 8.
After centrifugal separation unit 7 separates cinder dirt, the dust-absorbing airflow that contains trickle dust passes fore filter 16, passes to be located at the filter unit 14 that dust-collection element covers 12 inside again, and trickle dust is filtered out, state with cleaning sucks in the electric fan 6, is discharged in the atmosphere again.
In addition, stockpile when dust stockpiles dust in the unit 8 pouring out, the 1st kind of method is that dust-collection element 5 is taken out from main body, catch handle portion 11, when catching handle portion 11 by being pressed on its inboard functional unit 15, remove fixing between dust-collection element 5 and the dust-collection element lid 12, the lid of the dust-collection element on the dust-collection element 5 12 is opened.Then, from the peristome 13 on the top of dust-collection element 5 dust of inside is poured out.
The 2nd kind of method be, after dust-collection element 5 is taken out from main body, opens the discharge flap 19 of the bottom that is located at dust-collection element 5, from outlet 18 dust that dust stockpiles 8 inside, unit outwelled.
As shown in Fig. 1～Fig. 3, because the centrifugal separation unit 7 in the dust-collection element 5 stockpiles the inclination that unit 8 is 30 ° of degree angles with respect to dust, therefore stockpile unit 8 with centrifugal separation unit 7 and dust and be upper and lower and compare to the occasion of arranged in series, whole height can be compressed.In erect type dust catcher and accumbency type dust catcher, can utilize the present invention.In addition, though be the inclination that is 30 ° of angles in the present embodiment, in fact the angle of inclination can reach above-mentioned effect as long as between 5 °～85 °.
In addition, because centrifugal separation unit 7 is inclined as shown in Fig. 1～Fig. 3, dust can produce the power that moves downwards under the mass action of himself, what exist when therefore, centrifugal separation unit 7 and dust stockpile unit 8 and be provided with in horizontal direction can not send into the dust of separating from dust-absorbing airflow the problem that dust stockpiles the unit 8 effectively and also can solve.
In addition, stockpiling the dust that stockpiles in the unit 8 at dust can be blown afloat under the effect of the centrifugal flow in the centrifugal separation unit 7 once more, like this, dust just is not easy attached on the filter unit in the centrifugal separation unit 7 16, thereby can prevent the decline of dust-absorbing strength.
In addition, the centrifugal force that takes place in centrifugal separation unit 7 does not have too big difference in the upper and lower of centrifugal separation unit 7, so can alleviate the decline of dust-absorbing strength.
In addition, because centrifugal separation unit 7 is inclination, the shape that dust stockpiles unit 8 freely is not set by can on restriction ground, can be arranged to greatly as far as possible, makes the control of dust capacity increase of dust-collection element 5, thereby can reduce the frequency of tipping rubbish, the raising ease of use.
By resemble shown in Fig. 4,5 the shape of dust-collection element 5 is attenuated, and be arranged side by side in the horizontal direction, the global shape of dust-collection element 5 can be made the sort of cross section shown in Fig. 4 and roughly be the rectangle that becomes to have fillet; Can also dispose the dust-collection element of a plurality of identical or different sizes, scope of design can enlarge, and simultaneously, also can finish setting under the situation of having only very little space.
In order to carry out centrifugal control of dust, the shape of centrifugal separation unit 7 must be made roughly cylindrical or conical.And when centrifugal separation unit spare only is provided with 1, improve the size that dust collecting performance must increase centrifugal separation unit, but so, it is big that the dust collector host body also will become.In the present invention, by a plurality of centrifugal separation units 7 are set, the free degree of structure configuration has increased, and can realize the miniaturization of body under the condition that does not reduce dust collecting performance.
In addition, as shown in Figure 5, the dust-absorbing airflow that enters from air entry 9 by approximate equality be split into multiply, so the dust that sucks from suction nozzle also can be diverted to approximate equality each dust-collection element 5, make that the rubbish amount of stockpiling in each dust-collection element 5 is also basic identical.Therefore, can prevent that the amount of the stockpiling difference in each dust-collection element 5 from causing down the problem that also can't grasp the period of dust.
In addition, owing to be provided with the handle portion 11 that is used to carry dust-collection element 5 on dust-collection element 5, it is very easy that the carrying of dust-collection element 5 will become, and can prevent the hand of making dirty when tipping rubbish, and degree easy to use can be improved.
In addition, owing to peristome 13 is set on the roughly top of dust-collection element 5, peristome 13 is provided with its dust-collection element that covers lid 12, the inside of dust-collection element lid 12 is provided with the filter unit 14 that the dust-absorbing airflow that will suck is filtered again, so the fine dust in the dust-absorbing airflow of separating from centrifugal separation unit 7 will stockpile near filter unit 14.Like this, can improve trickle dust attached to problems such as the performance decline that causes on the electric fan 6, security performance deteriorations.Simultaneously, can will stockpile at the dust of dust-collection element 5 inside from peristome 13 at an easy rate after dust-collection element lid 12 opened and pour out, ease of use can be improved.
In addition, fix or remove between dust-collection element lid 12 and the dust-collection element 5 near the handle portion 11 that fixing functional unit 15 is arranged on dust-collection element 5 by being used to make, manipulation operations parts 15 smoothly just under the state of holding handle portion 11 like that shown in Fig. 6 stockpile unit cover 12 with dust and open.Like this, just needn't change actions such as hand in when falling the dust, ease of use can be improved.
In addition, covered 12 o'clock opening dust-collection element, because the direction of manipulation operations parts 15 also is the direction of grasp handle portion 11, so dust-collection element 5 can be clenched, and dust-collection element 5 problem such as drop also can prevent trouble before it happens.
As shown in Fig. 2,7, for those as in centrifugal separation unit 7, do not separate, let alone do not enter that dust-collection element lid 12 is inner can be attached to the dust that its performance is descended, by fore filter 16 it is stockpiled earlier.Like this, dust attached on the filter 14, phenomenon that its performance is descended just can be inhibited.In addition, cylindric by the shape of fore filter 16 is roughly made, the area of fore filter 16 just can strengthen, and dust stockpiles the performance decline that causes and also can be inhibited in fore filter 16.
In addition, as shown in Fig. 2,7, the bottom of fore filter 16 is provided with discoid guard block 17, and the surface of this discoid guard block 17 roughly is perpendicular to the central shaft on the vertical direction of centrifugal separation unit 7.Swirling eddy in the centrifugal separation unit 7 is after the dust that dust is transported to the bottom stockpiles in the unit 8, and swirling eddy is reflected in the bottom surface that dust stockpiles unit 8, thereby dust is blown to the top once more.But at this moment; because guard block 17 can block ascending air in the front of centrifugal separation unit 7; and swirling eddy pushed back the bottom once more, dust will turn back to the inside of centrifugal separation unit 7, therefore can prevent the problem that hinders the new dust that sucks to separate.
The another kind of structure of guard block 17 has been shown among Fig. 8 in addition.The bottom of fore filter 16 is provided with discoid guard block 17, and the surface of this discoid guard block 17 roughly is perpendicular to the central shaft on the vertical direction of centrifugal separation unit 7.Swirling eddy in the centrifugal separation unit 7 is after the dust that dust is delivered to the bottom stockpiles in the unit 8, and swirling eddy is reflected in the bottom surface that dust stockpiles unit 8, thereby dust is blown to the top once more.But at this moment,, and swirling eddy is pushed back the bottom once more because guard block 17 can block ascending air in the front of centrifugal separation unit 7.In structure shown in Figure 8; the surface of guard block 17 stockpiles the central shaft of vertical direction of unit 8 for roughly being in vertical direction with respect to dust; can come reliably it to be stopped by the surface of approximate vertical for stockpile the swirling eddy that rises unit 8 along dust; therefore; dust can turn back to centrifugal separation unit 7 inside, thereby hinders problems such as the new dust that sucks separates just can prevent trouble before it happens.
Shown in Fig. 9,10, since the periphery wall that dust stockpiles unit 8 be provided be used to discharge dust outlet 18, and be provided with the discharge flap 19 that covers outlet 18, therefore, discharge flap 19 as long as open, just can be easy to dust is poured out from the outlet 18 of dust-collection element 5 bottoms, ease of use can improve.
In addition, stockpile on the rear surface of unit 8 by outlet 18 is located at dust, be opened even discharge flap 19, dust can not dropped out downwards yet, and the user can pour out dust with suitable amount and speed according to the will of oneself.Like this, dust also just drops out, causes the problem that dust is at random also can solve on every side immediately when discharge flap 19 is opened, and ease of use can be improved.
In addition, though the 1st above-mentioned embodiment is the vertically accumbency type electric dust collector of configuration of a kind of dust-collection element 5,, the words that the present invention is applied on the erect type electric dust collector also can reach same effect.
Next, by Figure 11～17 electric dust collector among the 2nd embodiment of the present invention is described.Wherein, put on identical symbol, and omitted explanation it with component part identical among above-mentioned the 1st embodiment.
Figure 11,13 is the partial structurtes sectional view of the dust collector host body of the electric dust collector in the present embodiment, and Figure 12, Figure 14～17 are mounted in the partial structurtes sectional view of the dust-collection element in the dust collector host body.
In the 1st above-mentioned embodiment, handle portion has been located at the rear portion of dust-collection element 5.And in the present embodiment, handle portion has been located at the top of dust-collection element 5.
In Figure 11～17, reference number 4 is the inner dust collector host body that is provided with the electric fan 6 that is used to attract dust, 5 for being connected, can installing and removing dust-collection element freely with the suction nozzle (not shown) that is used for sucking dust on dust collector host body 4,30 is handle portion, this handle portion 30 is positioned at roughly top of dust-collection element 5, one end is provided with turning cylinder 31, and the retainer 32,33 that the other end is provided with the restriction rotational angle remains on buckling clamping part in the dust collector host body 4 for making dust-collection element 5.
Under the nonrotating state of handle portion 30, the handle bossing 34 that is located on the handle portion 30 withstands the buckling clamping part end face 35 that is located on the buckling clamping part 33, stops the motion of buckling clamping part 33.At this moment, the claw 36 that is located on the buckling clamping part 33 hooks the buckling clamping part fixture 37 that is located on the dust collector host body 4, makes between dust-collection element 5 and the dust collector host body 4 and is maintained fixed state.
When handle portion 30 rotates, handle bossing 34 will break away from from buckling clamping part end face 35, buckling clamping part 33 will be that rotate in the axle center with the central shaft 38 of the approximate centre portion that is in buckling clamping part 33, the claw 36 that is located on the buckling clamping part 33 will break away from fixing will being disengaged between dust-collection element 5 and the dust collector host body 4 with the buckling clamping part fixture 37 that is located on the dust collector host body 4.
In addition, because the length setting of buckling clamping part 33 must be greater than the length 36 from central shaft 38 to claw, therefore, even also can produce the strain of crossing the step on the buckling clamping part fixture 37 at least under the state that self is fixed.
In addition, reference number 39 is for maintaining the handle portion fixture of handle portion 30 under nonrotating state, prevents to cause handle portion 30 arbitrarily to rotate because of accidental shock and vibration.
As shown in Figure 16,17, be in when nonrotational at handle portion 30, the protuberance 40 that is located at handle portion 30 inside inserts in the recess 41 that is located on the buckling clamping part, stops buckling clamping part 33 generation activities.In addition, even the concavo-convex relationship here conversely, also can play identical effect.In handle portion 30 rotates, the jut 42 that is located on the side of inside of handle portion 30 will contact with the end 43 of buckling clamping part 33, and buckling clamping part 33 is rotated, thereby remove fixing between dust-collection element 5 and the dust collector host body 4.
In addition, on dust-collection element 5, be provided with the box-like member 44 that is the form that covers buckling clamping part 33, be provided with the inboard that is positioned at box-like member 44, the main body box-like member 45 that is used under the installment state of dust-collection element 5, maintaining box-like member 44 in the dust collector host body 4.In addition, box-like member 44 be make buckling clamping part 33 with before the buckling clamping part fixture 37 of dust collector host body 4 contacts earlier with main body box-like member 45 contacted structures.
Operational circumstances and effect in the above-mentioned formation are described below.
Under the state that normal condition that is handle portion 30 do not rotate, as as shown in Figure 11,12, by the handle bossing 34 that extends from handle portion 30 is contacted with buckling clamping part end face 35 on being located at buckling clamping part 33, the motion of buckling clamping part 33 is prevented from; And take place between dust-collection element 5 and the dust collector host body 4 to fix by claw 36 that is located on the buckling clamping part 33 and the buckling clamping part fixture 37 that is located on the dust collector host body 4 being fixed with each other, making.
During the dust that in abandoning dust-collection element 5, stockpiles, handle portion 30 can be lifted upward.What at this moment, handle portion 30 will be as shown in Figure 13 is that the center rotates with turning cylinder 31 like that.When handle portion 30 rotates, such buckling clamping part end face 35 that breaks away from that handle bossing 34 is incited somebody to action as shown in Figure 14, buckling clamping part 33 will be that the center rotates with the central shaft 38 of the approximate centre portion that is in buckling clamping part 33, the claw 36 that is located on the buckling clamping part 33 will spin off from the buckling clamping part fixture 37 on being located at dust collector host body 4, make fixedly being disengaged between dust-collection element 5 and the dust collector host body 4, thereby dust-collection element 5 can be pulled down from dust collector host body 4.
That is, only just can realize removing and fix and pull out dust-collection element 5 these two operations between dust-collection element 5 and the dust collector host body 4 by an action.In addition, because retainer 32 blocks handle portion 30 it can not be rotated further, come compared with the stretching shape of mentioning again, tensile strength will improve greatly, thereby can make electric dust collector not fragile, realize very high reliability.
In addition, because the length of buckling clamping part 33 is configured to greater than the length 36 from central shaft 38 to claw, even at the state of turning handle hand 30 not, be under the state that is fixed of buckling clamping part 33 dust-collection element 5 to be installed on the dust collector host body 4, buckling clamping part 33 just can be crossed the step of the buckling clamping part fixture 37 on the dust collector host body 4 as shown in Figure 15 like that by the strain of himself, make claw 36 that breakage not take place and just can hook buckling clamping part fixture 37, thereby can make electric dust collector realize very high reliability.
In addition, be used under nonrotating state handle portion 30 securing handle portion fixtures 39 by being provided with like that as shown in Figure 11, dust collector host body 4 be subjected to unexpected impact and during vibration handle portion 30 just can arbitrarily not rotate yet.Like this, the fixedly quilt of buckling clamping part 33 is arbitrarily removed, and dust-collection element 5 comes off from dust collector host body 4, and dust is at random, and dust-collection element 5 is impaired etc., and problem also can be avoided.
In addition, as shown in Figure 12, that is to say under the nonrotating state that the handle bossing 34 that is located on the handle portion 30 and buckling clamping part end face 35 on the buckling clamping part 33 come in contact on this point and be fixed because buckling clamping part 33 just is at handle portion 30, therefore, as long as handle portion 30 is rotated, buckling clamping part 33 just can be removed fixing.Like this, the locking of dust-collection element 5/unclamp and can carry out easier and more reliably, ease of use can improve.
In addition, handle portion 30 be in nonrotational in, by making protuberance 40 such the insertion in the recess 41 that is located on the buckling clamping part 33 as shown in Figure 16 that is located at handle portion 30 inside, just can stop the motion of buckling clamping part 33.Therefore, if turning handle hand 30 and want dust-collection element 5 is pulled down not, though the claw 36 of buckling clamping part 33 can produce the tendency that skids off the buckling clamping part fixture 37 on colluding the dust collector host body of speeding up 4, but because two sides that recess 41 has been clamped protuberance 40, buckling clamping part 33 can not rotate.Therefore, fixing between dust-collection element 5 and the dust collector host body 4 can be kept, thereby can prevent the appearance of the situation that dust-collection element 5 comes off when being subjected to unexpected impact and vibration, improves ease of use.
In addition, exchange mutually, also can reach same effect at these locational recess, protuberance.
In addition, when handle portion 30 rotates, roughly be located at jut 42 will come in contact with the end 43 of buckling clamping part 33 like that as shown in Figure 17 on the side of inside of handle portion 30, buckling clamping part 33 is rotated, thereby can remove fixing between dust-collection element 5 and the dust collector host body 4 fully.Like this, can prevent from dust-collection element 5 when dust collector host body 4 is pulled down stuck phenomenon is taken place, improve ease of use.
