Further, it is provided with sealing ring between described poor efficiency cyclone chamber and secondary cyclone bucket, it is ensured that the air-tightness within dust arrester, reduces the pressure loss.
Further, described dust collect plant includes dirt cup bottom, and described dirt cup is renovated with dirt cup bottom and is connected, and is provided with sealing ring between described dirt cup and dirt cup bottom, and described dirt cup is provided with bottom button release, it is simple to cleaning dust storage chamber dust.
Further, described exhaust apparatus includes dirt cup lower cover and dirt cup upper cover, and dirt cup is covered with air outlet, for being discharged by gas complete for dedusting.
Further, described dirt cup bottom is divided into inside and outside two cavitys by described whirlwind cover, and the dust that poor efficiency cyclone chamber removes is collected by outside dust storage chamber, and the dust that secondary cyclone bucket removes is collected by inner side dust storage chamber.
Further, described dirt cup is covered with handle lower cover, handle upper cover and dirt cup snap close, it is simple to use and operate.
Further, described secondary cyclone bucket has several, described single secondary cyclone bucket is funnel-form, each described secondary cyclone bucket size is identical, and be distributed in the form of a ring, make air-flow strictly divide equally, the funnel structure of single secondary cyclone bucket radius when gas Liu Dao bottom reduces centrifugal force and strengthens, improve efficiency of dust collection, and make dust expulsion efficiency improve.
Further, described secondary cyclone bucket lower end is provided with cone end breach, and breach at the bottom of described cone is an inclined-plane so that the dust of removing is easier to be discharged and dust storage chamber is concentrated and is convenient to clean to the inside.
Compared with prior art, the utility model has the advantage of: when the air-flow with dust is inhaled into from air inlet, rotating in poor efficiency cyclone chamber, internal dust tentatively carries out dedusting by mesh cleaner unit under pressure and centrifugal action, and these dusts focus on outside dust storage chamber. Then pass through the air flow contacts of rough dusting to whirlwind cover, tangential inlet it is advanced under pressure, after air-flow is strictly divided equally, pass through tangential inlet, secondary cyclone bucket is entered along bucket wall, air-flow rotates in the shape of a spiral in the structure of secondary cyclone bucket, dust produces centrifugal force and makes dust be discharged into inner side dust storage chamber from cone end breach. Design good dedusting effect of the present utility model, efficiency is high, simple in construction and durable, basket strainer is damaged little, use cost is low, persistently inhales ash ability strong.

Detailed description of the invention
As Figure 1-3, from air inlet 1, gas being pressed into this vacuum cleaner spiral air inlet device under pressure, air-flow subsequently enters poor efficiency cyclone chamber 2, passes through mesh cleaner unit 4 at pressure and centrifugal action downstream, air-flow tentatively carries out dedusting, and dust enters outside dust storage chamber 3. By the air flow contacts of rough dusting to whirlwind cover 11, above it is advanced into tangential inlet 5. Tangentially entrance, air-flow makes corkscrew motion along bucket wall, and then dust moves downward under centrifugal force and action of gravity and discharges from cone end breach 7, and dust enters inner side dust storage chamber 8. Air-flow continues up by venthole 9 with basket strainer 22, and dust runs into basket strainer 22 and is downwardly into secondary cyclone bucket 6 and again carries out dedusting, discharges from cone end breach 7. The air-flow that dedusting completes flows out from air outlet 10. This utility model utilizes the design of secondary cyclone bucket to complete the dedusting to air-flow, reduces the loss of dedusting layer, strengthens effect and the efficiency of dedusting so that the sustainability of dust suction increases, it is to avoid secondary pollution.
As in figure 2 it is shown, the geometrical relationship of tangential inlet 5 and secondary cyclone bucket 6 upper end cylinder is tangent, it is ensured that air-flow reduces flow velocity loss, the pressure loss from tangential inlet when entering, and makes air-flow move in the shape of a spiral, strengthens dust removing effects.
As shown in Figure 3, it is provided with sealing ring 12 between described mesh cleaner unit 4 and secondary cyclone bucket 6, increases the air-tightness of mesh cleaner unit 4 and secondary cyclone bucket 6, between described dirt cup 13 and dirt cup bottom 14, be provided with sealing ring 15, the design of sealing ring keeps pressure and air-flow velocity, it is ensured that dedusting effect.
As it is shown on figure 3, described bottom button release 16 facilitates the dust that the internal dedusting of cleaning goes out, run up on dirt cup bottom 14 under gravity, when by lower bottom cover button release 16, dirt cup bottom 14 is convenient to clean dust with dirt cup 13 disengaging.
As it is shown on figure 3, described dirt cup 13 is provided with dirt cup lower cover 17 dirt cup upper cover 18, described dirt cup upper cover 18 is provided with air outlet 10, and described dirt cup 13 is covered with handle lower cover 19, handle upper cover 20 and dirt cup snap close 21, it is simple to can be hand-held when use.
Each secondary cyclone bucket 6 annular distribution described, size is identical, single secondary cyclone bucket 6 is funnel structure, structure designed by this utility model enters secondary cyclone bucket 6 after air-flow is divided equally, from tangential inlet 5 enter after for the helical movement, and the centrifugal force that the speed remaining air-flow to greatest extent produces when making air-flow for the helical movement can be maximum, funnelform design makes the more downward centrifugal force of air-flow more big, improves dust removing effects and efficiency of dust collection.
As shown in Figure 3, breach 7 at the bottom of described cone is an inclined-plane, it is easy to secondary cyclone bucket internal dust discharge, the outlet of secondary cyclone bucket is conducive to the discharge of dust for inclined-plane, improve dust removing effects and efficiency of dust collection, and the dust discharged can dust storage chamber 8 central motion to the inside, it is simple to cleaning, it is to avoid secondary pollution.
