As shown in Fig. 8 (c), the cross sectional shape of 55 front portions, centrifugation chamber forms the smooth D word shape of end face, this is that anterior face for the dust housing unit 4 that makes the part shell that constitutes dust collector host body 1 seems low, and increases the diversity in the configuration design.In addition, from second connected entrance 56, extend tubular flange 55c, flow back to again in the centrifugation chamber 55 thereby the thin dirt that enters thin dirt chamber 57 is unlikely near a side of thin dirt chamber 57.

In addition, the housing parts that forms thick dirt chamber 53 and thin dirt chamber 57 in the dust box box body 50 is made by trnaslucent materials, thereby can see the amount of dust of piling up from the outside clearly.

The rear side of dust box box body 50 is provided with brush resettlement section 50a (Figure 10), and brush resettlement section 50a is used to accommodate the cleaning brush 63 that the dust that sticks on dust housing unit 4 and the component parts thereof is cleaned.

Be provided with in the filter unit 51: framework 64; Be converted into rugosity, its crease and be vertically the aflter-fillter 65 that is arranged on the framework 64 (promptly vertical); Form the bridging shape in the inboard of framework 64, secondary filter 65 remained on the convex tendon body 66 on the direction with its crease orthogonal; With the dedusting plate of making by whippy metal materials such as steel plates 67.The bottom of dedusting plate 67 relies on the elastic force of himself to be pressed on framework 64 1 sides, and top is installed on the top of framework 64.The end in the downstream of the framework 64 of filter unit 51 is provided with and constitutes an one or an integrally formed circle antelabium 68 with it.When dust housing unit 4 installed on the dust box reception room 5, the surface that is positioned at dust box reception room 5 one sides of the partition walls 29 in above-mentioned antelabium 68 and the dust collector host body 1 compressed mutually, thus make electric fan 2 as the time be unlikely and suck outer gas.

The front surface 69 of filter unit 51 covers the upstream side of aflter-fillter 65, simultaneously, when filter unit 51 installed in the dust box box body 50, the front surface 69 of above-mentioned filter unit 51 also covered separately rear opening portion 53a, 55a, the 57a of thick dirt chamber 53, centrifugation chamber 55, thin dirt chamber 57 airtightly.In addition, be provided with first opening 70, second opening 71 and the 3rd opening 72 on the front surface 69 of filter unit 51 with on the corresponding respectively position of described rear opening portion 53a, 55a, 57a.Be respectively equipped with filter 70a, a 71a and 72a on first opening 70, second opening 71 and the 3rd opening 72, prevent that thick dirt and thin dirt from invading in the filter unit 51.

The lower end of dedusting plate 67 is provided with extended lug 67a, as as shown in the part-structure sectional view among Figure 13, Figure 14, when dust housing unit 4 was encased in the dust box reception room 5, lug 67a was promptly near the attack roller 33 that is located on the dust collector host body 1.Under such state, pulling is during power line 32, and attack roller 33 will rotate linkedly with pulling out operation, and it is that move at the rear along the flow direction of air that the elastic force that the attack sheet 33a that makes the mountain top shape will head on dedusting plate 57 makes the lug 67a on the dedusting plate 67; When lug 67a slipped over attack sheet 33a (with reference to Figure 14), dedusting plate 67 was got back to the left side at original place quickly under the effect of elastic force.At this moment, dedusting plate 67 will clash into the front end of convex tendon body 66, and convex tendon body 66 is added strong impact; Thus, also to adding strong vibration on the aflter-fillter 65, thereby the thin dirt that will stick on the aflter-fillter 65 shakes, and makes the strainability of aflter-fillter 65 obtain bringing back to life.

Below operational circumstances in the above-mentioned formation and effect thereof are described.

When bring into use electric dust collector, when power line 32 is pulled out from dust collector host body 1, the flange 22a of power line winding roll 22 will rotate linkedly with such operation of pulling out, its revolving force passes on the 3rd gear 28, second gear 27, first gear 35 successively, and attack roller 33 is rotated.During 33 rotations of attack roller, the attack sheet 33a on it carries out attack to the lug 67a that is located on the dedusting plate 67, thereby adds strong impact on the convex tendon body 66 to filter unit 51.Like this, the thin dirt that sticks on the aflter-fillter 65 till the last dust suction will be shaken, and the filter capacity of aflter-fillter 65 will be restored.

Next, when power line 32 is inserted on the not shown wall socket, starts electric dust collector, beginning dust suction operation, the attraction that electric fan 2 carries out will be delivered on the suction nozzle 16 from first opening 70, second opening 71, the 3rd opening 72, filter 70a, 71a, 72a, thick dirt chamber 53, centrifugation chamber 55, thin dirt chamber 57, flexible pipe 8 and an extension pipe 13.Like this, the air that contains dust that sucks from suction nozzle 16 will be by the air entry 10 of dust collector host body 1, enters into thick dirt chamber 53 as the crow flies from the suction inlet 52 of dust box box body 50, bumps against on filter 70a, and is captured at this, piles up.

Because the attraction that electric fan 2 produces also affacts in the centrifugation chamber 55, the quilt in the thick dirt chamber 53 is got an airborne part of removing thick dirt and can be passed the connected entrance 54 that is positioned at suction inlet 52 1 sides, flow in the centrifugation chamber 55.Here, because air flows into the centrifugation chamber 55 along the surface of a filter 71a and from its tangential direction, can produce effective centrifugal separating effect to dust.Meanwhile, dust will become and be difficult to adhere on filter 71a, be difficult for the phenomenon that dust is blocked mesh takes place, so the decline of a filter 71a hollow air pressure damage can be inhibited.

The connected entrance 56 of thin dirt from the part perisporium that is located at centrifugation chamber 55 of being separated by centrifugation by centrifugation chamber 55 drops to the thin dirt chamber 57.On the other hand, pass air behind filter 70a, a 71a, the 72a, that contain thin dirt inflow is in the aflter-fillter 65 of rugosity, thereby thin dirt is trapped.The thin dirt that is trapped then uses electric dust collector in next time, when power line 32 is pulled out by dedusting plate 67 abates in addition.

Adopt after the above-mentioned formation, because thick dirt has been captured by thick dirt chamber 53 in advance, the load that dust is carried out centrifugation in the centrifugation chamber 55 can alleviate, and captured by thin dirt chamber 57 again at this thin dirt of separating, so the situation that thin dirt remains in the centrifugation chamber 55 can be inhibited, thereby can the very high centrifugation performance of long term maintenance.

In addition, if the air-breathing crushing in the thin dirt chamber 57 is set for greater than the air-breathing crushing in centrifugation chamber 55 and the thick dirt chamber 53, the situation that thin dirt remains in the centrifugation chamber 55 also can be inhibited, thereby can the very high centrifugation performance of long term maintenance.

In addition, at least reach 1.3 cubic metres/minute by setting the area of width of mesh, material and first opening 70 of filter 70a, a 71a, 72a filter separately, B71, C72 for make centrifugation chamber 55 air-breathing air quantity, just can fully guarantee to be used for air capacity that electric fan 2 is cooled off, thereby prolong the life-span of electric fan 2, and can prevent electric fan 2 abnormal heating, fault such as burn and take place.

In addition, as shown in Figure 12, because filter 70a, 71a, a 72a is set up at grade, thus will become very simple to their cleaning, nor the cleaning leakage can take place, very easy to use.In addition, though filter 70a, 71a, a 72a in the foregoing description are arranged on the same one side, but, have some drops (as the drop about 6mm) slightly between filter 70a, a 71a, the 72a or between the surface of they and front surface 69, the convenience that cleaning is got up can not change yet.

In addition, owing to be to make attack roller 33 be rotated, the lug 67a of dedusting plate 67 is carried out attack, utilizes its reaction force to add impact on described framework 64 again in the utility model, therefore, dedusting plate 67 will add on the framework 64 that the flow direction with air is in the impact on the rightabout (that is stacked direction of dust), the lip-deep dust of the upstream side that sticks to aflter-fillter 55 is shaken, make aflter-fillter 65 recover filter capacity; Simultaneously, since dedusting plate 67 not to directly adding impact on the aflter-fillter 65, so the life-span of aflter-fillter 65 can prolong.

In addition, by with power line 32 pull out the operation interlock, attack roller 33 is rotated, therefore, there is no need special the drive source that attack roller 33 is rotated to be set, thereby can reduce the manufacturing cost of dedusting mechanism.In addition, rotate linkedly by making attack roller 33 and accommodating of power line 32 operate interlock or operate and accommodate the operation of operating two sides with pulling out of power line 32, the chance of the rotation of attack roller 33 will increase, and dust removing effects also can be improved.

In addition, though do not illustrate among the figure, attack roller 33 also can rotate under the special motor-driven that is provided with.Like this, the formation of dedusting mechanism can be simplified, and can make dust removing effects become stable.

In addition, be fixed on the upper end of framework 64 by the upper end with dedusting plate 67, can make the simplification that becomes of the formation of dust collector host body 1 one sides, it is stable that dust removing effects also can keep.

In addition, because aflter-fillter 65 is rugosity, and its crease is in vertical direction, therefore the dust of pounding out fallen downwards with very high efficient, and can prevent that dust from adhering on the aflter-fillter 65 once more.

In addition, the surface of the upstream side by making aflter-fillter 65 slightly turns forward, and the dust of pounding out is fallen downwards with very high efficient, and the dust of being pounded out is adhered on the aflter-fillter 65 once more.

In addition, because framework 64 is by resin forming, the convex tendon body 66 that the folded part of aflter-fillter 65 is connect is arranged to one with described framework 64, and dedusting plate 67 is again that this convex tendon body 66 is knocked, therefore, impact is delivered on the whole aflter-fillter 65 by convex tendon body 66, thereby can improves the effect that dust is pounded out.

In addition, also can resemble shown in Figure 10 dedusting plate 67 is severed in intermediate section, about formation 2, the lug 67a by separately carries out attack at different moment pair roller 33.Required pulling force or the torque that drives attack roller 33 motor rotating can reduce by half when like this, pulling out power line 32.In addition, the partitioning scheme of dedusting plate 67 also is not limited to 2 to be cut apart, and also can carry out 3 cutting apart, 4 cut apart.

In addition, if dedusting plate 67 is set at more than the 150G (acceleration of gravity) by the impulsive force that framework 64 is added on the aflter-fillter 65, can make air quantity recover about 80% of initial value.

In addition, owing to be provided with the flange 33b that lug 67a to dedusting plate 67 carries out the attack sheet 33a of attack and is arranged on its both sides and described attack sheet 33a is clamped in the attack roller 33, and lug 67a enters between two flange 33b, therefore, can prevent that dust removing body from opening when the dedusting partially from attack sheet 33a, simultaneously, dust etc. also is difficult for accumulating on attack roller 33.

As mentioned above, electric dust collector in the utility model is owing to can dispose peculiar smell in the dust by simple device, peculiar smell in the exhaust is reduced significantly, and the dust removal performance excellence of filter, to dedusting plate to directly not being applied with impact on the filter, therefore, breakage can not take place in filter, can be widely used in various family expenses, professional electric dust collector, the air cleaner etc.
