Description of drawings

Fig. 1 is a structural representation of the present utility model.

Fig. 2 is the A-A cutaway view of Fig. 1.

The specific embodiment

As shown in Figure 1 and Figure 2, this cyclone type secondary separation dust cup of vacuum cleaner comprises the housing 1 of dirt cup, is opened in air outlet 2 on the housing and the air inlet 3 tangent with the housing perisporium, places separator and support 4 in the housing.The air inlet 13 of described separator is arranged on the Lower Half of circular cowling 12.Its position is lower than the air inlet 3 of housing.Be provided with the cylindrical shell 6 that the upper end of settling side by side more than two has tangent air inlet 7 in circular cowling, the cylindrical shell among the figure is set side by side with seven.The top of circular cowling and cylindrical shell links to each other with support.The tangent air inlet 7 of cylindrical shell 6 upper ends can be provided with more than two, and the air inlet 7 among the figure is two.The air-out short tube 8 that a coaxial setting is arranged in each cylindrical shell and communicate with support 4 bottom outlets, at the cylinder inboard wall that is lower than short tube a conical shell 9 that bore is up big and down small is set, connect a shading ring 10 corresponding to the conical shell lower end, the upper end of shading ring radially is fixed on the conical shell by three dowels, make shading ring inwall and conical shell small end outer wall leave annular gap 21, the upper end of shading ring is a little more than the conical shell lower end.The bottom of shading ring 10, cylindrical shell 6 is sealed by base plate 23, thereby at second dust-collecting cavity 11 that forms on the base plate between cylindrical shell and the shading ring.The periphery of base plate 23 is provided with the cage 5 that Open Side Down.The cage below is first dust-collecting cavity 19 of dirt cup.The air inlet of the Lower Half of described circular cowling 12 can be the circular port that is distributed in sidewall, also can be lattice-shaped.Circular cowling Lower Half among the figure cuts substantially, stays the sidewall bar that top links to each other with base plate.Above-mentioned described cylindrical shell 6 and shading ring 10 its diameters can be upper and lower consistent cylindric, and cylindrical shell 6 diameters can be that up-small and down-big bullet, shading ring 10 diameters can be up big and down small reverse tapers.To increase the space of base plate top second dust-collecting cavity 11, increase the control of dust capacity.

Be connected with linkage between described base plate 23 and the bottom 16, base plate and circular cowling with rotating shaft 14 and axis hole cooperate, bottom 16 cooperates to be with rotating shaft and axis hole equally with case side and is rotatably connected, the other end of base plate by rotating shaft 15, connect connecting rod 22 and be with pitman shaft 17 on the bottom other end and be rotatably connected, buckling on the elasticity bottom button 18 that is installed on housing sidewall and the bottom 16 is interlocked.

The utility model is the same with conventional dust catcher, before the air inlet of electric fan filter is housed.

Below in conjunction with its operation principle of accompanying drawing narration.The dust catcher air channel that links to each other with the electric fan air inlet is connected with dirt cup air outlet 2, starting switch, electric fan work makes and produces negative pressure in the dirt cup, the air that has dust enters dirt cup inner chamber by dirt cup air inlet 3, because the periphery of dirt cup air inlet axis and dirt cup housing is tangent, thereby generation swirling eddy, again because separator air inlet 13 positions are lower than dirt cup air inlet, thereby after the air that has dust enters the dirt cup, promptly produce the quick whirlwind of downward spiral, dust is subjected to the effect of centrifugal force and gravity to be thrown toward perisporium and first dust-collecting cavity 19 to dirt cup bottom of falling.The dust that falls into dust-collecting cavity 19 because of the buffer action of cage 5 is difficult to be subjected to the influence of spiral air flow and rolls again, isolates most of dust with this.Only the air with a small amount of fine dust enters from the separator air inlet 13 below circular cowling 12 perisporiums, because blast strengthens, air-flow quickens, this part air enters cylindrical shell upper end air inlet 7 from the gap between circular cowling 12 and cylindrical shell 6 and cylindrical shell and the cylindrical shell perisporium, again owing to be subjected to guide effect with the tangent air inlet 7 of cylindrical shell perisporium again, the air that enters in the cylindrical shell produces swirling eddy equally, because of cylindrical shell 6 epicoeles 20 internal diameters big, entering conical shell 9 internal diameters downwards dwindles, this part air-flow blast increases, flow velocity is accelerated, and centrifugal force will be mixed with a small amount of thin dirt air separation once more, gets rid of to inwall and whirlpools down to shading ring 10 bottoms.Since the inertia thin dirt of whirlpooling down be subjected to gas shock again along the shading ring inwall by the annular gap 21 between conical shell bottom and the shading ring, fall on the base plate of second dust-collecting cavity 11.Through the air after twice separation through air-out short tube 8 be connected support bottom outlet, filter, dirt cup air outlet 2 and enter electric fan and discharge dust catcher.When in the needs cleanings dirt cup during dust, buckle 18 as long as press dirt cup bottom, bottom 16 is opened, because connecting rod 22 effects, cage and base plate are also opened simultaneously, the dusts in dirt cup first dust-collecting cavity 19 and the separator in second dust-collecting cavity 11 fall simultaneously and discharge outside the dirt cup.
