Abstract
Disclosed are a double-air-inlet dust cup and a dust collector provided with the double-air-inlet dust cup. The double-air-inlet dust cup and the dust collector provided with the double-air-inlet dust cup comprise the dust cup of the dust collector. Two air inlets are formed in the upper portion of the dust cup and are tangent to the periphery wall of the dust cup. The two air inlets are symmetrical about the center of the two air inlets. Sum of the cross sectional area of the two air inlets is larger than or equal to the cross sectional area of an original single air inlet. When air and dust enter into the two air inlets, rotating trails of the air and the dust on the dust cup wall are not crossed and intersected just like a double thread screw. Separating space of an original dust cup is utilized sufficiently, and therefore separating effect of the dust cup can be improved notably when overall air inlet quantity remains the same. The double-air-inlet dust cup and the dust collector provided with the double-air-inlet dust cup have the advantages of being simple in structure, convenient to process, good in separating effect and capable of being widely used in an existing single-time or multiple-time separating dust cup.
Description
Technical field
The present invention relates to a kind of dust catcher for cleaning, a kind of with the dust cup of dust collector of two air inlets and the dust catcher that this dirt cup has been installed specifically.
Background technology
Dust cup of dust collector in the market is all single air inlet, and this is because so relatively simple for structure, and in the use procedure of dust catcher, the effect that also can reach certain of separating of dust and air in the dirt cup.But if common dust cup of dust collector that only once separates, it is not reach real use meaning far away, this is because the filter of dust catcher is in use blocked soon, the air quantity that enters dust catcher descends thereupon, thereby reduced the suction power of dust catcher, and separating effect can inhale poorer and poorer, makes normally dust suction of dust catcher.People are in order to improve the separating effect of dust cup of dust collector, thereby keep sucking constant as far as possible or few change of power, generally all increase the separator of an one-level or two-stage in the dirt cup again.By the separation of twice or three times, to greatest extent the dust that sucks the dirt cup is separated from air, and is fallen into the dirt chamber of dirt cup bottom, make by in the air of filter with few dust.Like this dust catcher in use, its filter is just can not be very fast blocked and reduce and suck power, and can remain separating effect preferably.From the efficient dirt cup that separates in the market, the volume that is not the dirt cup is exactly more greatly that the structure of dirt cup inner separator is comparatively complicated, so their material cost is all higher.Multistage separator sucks power because complex structure affects dust catcher toward the contact meeting, and this is because its windage has increased, the cause that air quantity also reduces thereupon.
The scheme that also has a kind of pair of dirt cup dust catcher is as the dust catcher of application number 200610085862.4.The separating effect of this pair of dirt cup is to increase than common single dirt cup under certain condition, but the diameter that its most important condition is each dirt cup can only be slightly less than single dirt cup, and otherwise, its effect is also limited.When doing gyration according to particle, the computing formula (φ=-m ω 2r) that acts on the normal inertial force (centrifugal force) on particle can illustrate this point.When dust particle was done tangential gyration along the dirt wall of cup, in the situation that the suction of electric fan is constant, angular velocity omega was also relatively stable, and the centrifugal force that acts on particle is directly proportional to the radius of gyration.So the cost of dirt cup and main frame will improve a lot, and its volume is larger, packing and also corresponding increase of cost of transportation.In order to make the dirt cup volumes be unlikely to excessive, also all be designed to secondary separation.Also have similar product to rarely have listing abroad, because cost of manufacture is high not by popularization and application, so the Practical significance of two dirt cups and little.
Patent Office of the People's Republic of China is disclosed on September 24th, 2008, the patent No. is 200610077973.0 " a kind of multi-air intake separator and contain the cup device for dust of this device ", comprise the circular cylinder body and the conical shell that connect up and down, the coaxial discharge pipe that is arranged on circular cylinder body inside, the sidewall of described circular cylinder body is connected with two center lines and is involute shape, the longitudinal cross-section is the blast pipe of rectangle, the height and position of two blast pipes on circular cylinder body is identical, circumferential position staggers 180 °, their air inlet is positioned at through the same plane of the axis of circular cylinder body and towards the opposite.This is a separator that is used for the second-order separation dirt cup, and this separator has two air inlets, offers in order to improve separating effect.Although the air that dust catcher sucks separating with dust process first order dirt cup, enter existing minimizing of dust of second level separator, but it is very difficult here will separating dust and air fully, because one, the separating effect of common single air inlet dirt cup is limited, still there is more dust not separate, two, the air that sucks all will pass through this narrow space, and the distance of tangent air inlet that is positioned at the air outlet at separator center and separator is too near.Although a plurality of separators can be set in the dirt cup side by side, the cost of product will increase a lot, and its cost performance also so not high.Only have and improve to greatest extent the separating effect that the first order is the dirt cup, just can make the effect of second level separator perform to ultimate attainment.When common cyclone separating type dust remover work, in observation dirt cup, the path of dust and air separation process can be found, isolated dust only rotated at the bottom of drop to glass one week the left and right, if that is to say that a large dirt cup has only utilized a part of rotating separation space.So take full advantage of the separated space of the dirt cup approach that improves separating effect of can yet be regarded as.
Summary of the invention
The object of the invention is to defective and deficiency for above-mentioned prior art, for people provide a kind of separated space that can take full advantage of original dirt cup, improve two air inlet dirt cups of separating effect and the dust catcher that uses this dirt cup.
The technical solution used in the present invention is for achieving the above object: this pair air inlet dirt cup, and it comprises the dirt cup of dust catcher, offers two air inlets above described dirt cup, described air inlet and dirt cup perisporium are tangent.
Described two air inlet Central Symmetries.
The area of section sum of described two air inlets is more than or equal to the area of section of former single air inlet.
A kind of dust catcher that uses two air inlet dirt cups, the dirt cup that it comprises fuselage and is arranged at the fuselage side, place, fuselage chassis is provided with blast pipe, described dirt cup top offers two air inlets, described air inlet and dirt cup perisporium are tangent, be connected with two brasnch conducts on described blast pipe, brasnch conduct docks by the mode of inserting or buckle with the air inlet of corresponding dirt cup respectively after upwards bending is extended.
Described brasnch conduct has at least one to be segmentation, comprises horizontal fixed tube and moves longitudinally pipe, and is hinged by tubular axis between fixed tube and moving pipe.
Be segmentation away from a brasnch conduct of vacuum cleaner body.
The present invention is when air and dust enter two air inlets, they are the interference that can not cross one another at the rotational trajectory of dirt wall of cup such as the track of same double thread, take full advantage of the separated space of original dirt cup, in the situation that keep total intake constant, the separating effect of dirt cup will obviously improve.In the dust catcher that this dirt cup has been installed, because brasnch conduct wherein is segmentation, can brasnch conduct and dirt cup be thrown off to inner rotary, facilitate the dismounting of dirt cup.Have simple in structurely, easy to process, the advantage of good separating effect can be widely applied in existing single or multiple dust separating cup.

The specific embodiment
Show as Fig. 1, Fig. 2, the present invention is this pair air inlet dirt cup, and it comprises the dirt cup 1 of dust catcher, and described dirt cup 1 top offers two air inlets 2, and described air inlet 2 is tangent with dirt cup 1 perisporium, and described two air inlet 2 Central Symmetries.When air and dust entered two air inlets 2, they were the interference that can not cross one another at the rotational trajectory of dirt cup 1 wall such as the track of same double thread, take full advantage of the separated space of original dirt cup 1.The area of section sum of described two air inlets 2 is more than or equal to the area of section of former single air inlet, so that intake increases or keeps original constant.
The separating effect of two air inlet dirt cups is better than single air inlet dirt cup, and mainly containing the three aspects: reason affects.
The one, for each air inlet, single air inlet is than many one times of two air inlets along the entrained dust of dirt wall of cup swirling eddy, and they can not all be close to the rotation of dirt wall of cup and fall, and the considerable part dust are arranged along with the air-flow of direct sucking-off dirt cup is taken out of.And the monolateral amount of dust of advancing of two air inlets is a half the left and right relatively, and these dust particles can relatively be close to the rotation of dirt wall of cup and fall under the effect of centrifugal force, be difficult for along with the air-flow of direct sucking-off dirt cup is taken out of.
The 2nd, in the dirt cup dust particle under the centrifugal action that the suction of dust catcher electric fan produces with air separation, air is extracted out through dirt cup air outlet.But air must be through being arranged on filter or the second-stage separator of top, dirt cup center.For single air inlet, because air-flow and dust are concentrated and are one, the fractional dose of air will be given a discount, this is because it can not balancedly isolate the dirt cup by filter or second-stage separator etc., so at the bottom of having the part air to follow the dust rotational flow to fall the dirt cup, air and dust separation get not thorough.And two air inlets are divided into two strands symmetrically due to air stream, and it can more balancedly isolate the dirt cup by screen pack etc., so can isolate fully the dirt cup to air.
The 3rd, in the time of at the bottom of dust follows part air rotational flow to fall the dirt cup, because the inertia of air-flow can exist all the dust at the cup end also to stir to such an extent that kick up, the fraction dust can be taken out of the dirt cup by air-flow so again, and air quantity is larger, stir effectivelyer, the dust of being taken out of by air-flow is just more.Throughput at the bottom of single air inlet is fallen glass is many, stirs energeticallyer, and also much less of the throughput of two air inlet at the bottom of falling glass, so stir just much disappointing, the dust of being taken out of by air-flow like this is just relatively much few.
So on same dirt cup, in the situation that air quantity is equal, two air inlet dirt cups are more much better than the effect that single air inlet dirt cup separates air and dust.
As Fig. 3, Fig. 4, Fig. 5, shown in Figure 6, a kind of dust catcher that two air inlet dirt cups have been installed, the dirt cup 1 that it comprises fuselage 4 and is arranged at fuselage 4 sides, fuselage 4 places, chassis are provided with blast pipe 3, described dirt cup 1 top offers two air inlets 2, described air inlet 2 is tangent with dirt cup 1 perisporium, is connected with two brasnch conducts 5 on described blast pipe 3, and brasnch conduct 5 docks by the mode of inserting or buckle with the air inlet 2 of corresponding dirt cup 1 respectively after upwards bending is extended.Described brasnch conduct 5 has at least one to be segmentation, comprises horizontal fixed tube 5.3 and moves longitudinally pipe 5.1, and is hinged by tubular axis 5.2 between fixed tube 5.3 and moving pipe 5.1.Pipe 5.1 can be rotated relative to fixed tube 5.3.Moving pipe 5.1 can make the upper end of brasnch conduct 5 dock with the air inlet 2 of dirt cup 1 when dirt cup 1 rotates, and moving pipe 5.1 is when outwards rotating, and brasnch conduct 5 is thrown off with the air inlet 2 of dirt cup 1, to facilitate the dismounting of dirt cup 1.Wherein away from the brasnch conduct 5 of vacuum cleaner body 4 for segmentation, and identical with the conduit of original single air inlet dirt cup near a brasnch conduct 5 of fuselage 4, need not rotation.Doing like this is because away from the brasnch conduct 5 of vacuum cleaner body, larger activity space is arranged, and can significantly rotate, and when needs dismounting dirt cup 1, the moving pipe 5.1 that only needs outwards to rotate away from the brasnch conduct 5 of fuselage 4 gets final product, and is very convenient.
