The specific embodiment
As shown in the figure, this secondary cyclone dust separating cup of vacuum cleaner comprises dirt cup cup 11, is opened in the tangent with it dirt cup air inlet 3 of cup perisporium, is opened in the dirt cup air outlet 1 that covers with dirt that cup covers mutually and places separator in the dirt cup.This separator is provided with and is connected in the outer cylinder body 5 that connects between support 15 and the cage 7, the alternate separator air inlet 6 that is lower than dirt cup air inlet 3 that offers of outer cylinder body lower end perisporium, and this separator air inlet 6 is rectangular or circular and by uniform annular arrangement.The below of separator air inlet 6 is provided with flare cage 7.The outer cylinder body bottom links to each other with cage, and the outer cylinder body top links to each other with dirt cup housing by described connection support 15.The coaxial inner barrel 12 that is mounted with at outer cylinder body 5 centers, the top of inner barrel links to each other with the described support 15 that is connected, and the bottom is passed cage 7 and is linked to each other with dirt cup bottom.Described connection support 15 is big centre bore 16 belows young down, discoid bottom suitable for reading and connects a short tube 14.These short tube 14 internal diameters are less than inner barrel 12 internal diameters.Behind the inner barrel of these connection support 15 connection separators, the top of outer cylinder body, be held on the dirt cup rim of a cup.As Fig. 2, shown in Figure 3, the top of inner barrel top, separator air inlet (6) offers the inner barrel air inlet 2 tangent with the perisporium of inner barrel, it is made up of its passage axial and that the cup perisporium is tangent more than two or two, this inner barrel air inlet 2 or is as shown in FIG. rearranged by the annular array rotation by blade 17.The inner barrel air inlet 2 of inner barrel upper end communicates with the separator air inlet 6 of the outer cylinder body of below with annular gap space 4 between the outer cylinder body by inner barrel.The inwall of inner barrel 12 is provided with big, a following young divergent-cone wall 10 suitable for reading, the upper edge of this divergent-cone wall 10 is lower than short tube 14 bottoms, certain spacing is arranged at the bottom of divergent-cone wall and inner barrel bottom, is positioned at the dust-collecting cavity 9 of inner barrel bottom with formation.
Below in conjunction with accompanying drawing, narrate its operation principle.Air channel that links to each other with the electric fan air inlet and dirt cup air outlet 1 are joined, starting switch, produce negative pressure in the machine operation dust kicked up by somebody walking in front 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 position is lower than dirt cup air inlet position, thereby after the air that has dust enters the dirt cup, promptly produce the quick whirlwind of downward helical form, dust is subjected to the effect of centrifugal force and gravity to be thrown toward perisporium and falls to dirt cup bottom dust-collecting cavity 8.Because the buffer action of cage 7 falls into the influence that the dust of dust-collecting cavity 8 is difficult to be subjected to the top spiral air flow and rolls again, isolates most of dust with this.Only the air with a small amount of fine dust enters by the separator air inlet 6 that is opened in outer cylinder body 5 perisporiums, because blast strengthens, air-flow quickens, and this part air enters by the inner barrel air inlet 2 of inside and outside cylindrical shell annular gap space 4 from inner barrel top.Owing to be subjected to the guide effect of the tangent inner barrel air inlet 2 of inner barrel perisporium again, the air of inner barrel produces swirling eddy equally, because of inner barrel 12 epicoeles 13 internal diameters are bigger, enters the conical shell internal diameter downwards and dwindles again.This part air-flow blast increases, and flow velocity quickens, and centrifugal force will mix once more in airborne a small amount of thin dirt and separate, and get rid of to inwall and by conical shell 10, the dirt chamber 9 to the bottom of inner barrel of falling.Short tube 14 guiding of air after twice separation through connecting carriage center are entered electric fan and are discharged dust catcher by dirt cup air outlet.
