As seen from Figure 11, described second whirlwind assembly 6 comprises cyclone plate 61 and air gathering plate 62, when assembling described cyclone plate 61 and air gathering plate 62, the cotton layer 8 of sandwiched one between, described cotton layer 8 is provided with several cotton holes 81, described cyclone plate 61 stretches out tornadotron 611 downwards, the edge, upper end of described tornadotron 611 is the perforate edge of cyclone plate 61, described tornadotron 611 and described dust-leaking hole 52 one_to_one corresponding, the lower end of described tornadotron 611 is docked with dust-leaking hole 52, conveniently cyclone plate 61 and described deflector 5 is fixing, one or more montant is provided with at the upper surface of described deflector 5, correspondingly, described cyclone plate 61 is provided with the fixing hole coordinated with described montant, when the lower end of described tornadotron 611 is docked with dust-leaking hole 52, described montant inserts in corresponding fixing hole, screw is utilized to realize the fixing of deflector 5 and cyclone plate 61, each tornadotron 611 offers whirlwind inlet hole 612, described air gathering plate 62 stretches out duct set 621 downwards, the edge, upper end of described duct set 621 is the perforate edge of air gathering plate 62, described duct set 621 and described cotton hole 81 one_to_one corresponding, the shape of the shape in described cotton hole 81 and size and described duct set 621 upper end and in the same size, described duct set 621 lower end is inserted in described tornadotron 611, and described air gathering plate 62 utilizes cotton layer 8 to seal the upper end open covering tornadotron 611.
Described upper cover 7 is arranged on above air gathering plate 62, described upper cover 7 is provided with air outlet 71, described air outlet 71 is communicated with the entrance of power set of bleeding, as seen from Figure 2, described outer cup 1 sidewall offers the first air inlet 11, the sidewall of described interior cup 2 offers the second air inlet 21, described first air inlet 11, second air inlet 21, filter element 3, pod apertures 51, whirlwind inlet hole 612 forms current path, described current path and duct set 621, air outlet 71 is communicated with formation air-flow along separate routes, described path and tornadotron 611, dust-leaking hole 52, dust leg 42 is communicated with formation dirt body along separate routes.
In the dust catcher course of work, in gas and dust separating device of the present invention, air-flow specifically flows to and is: under the driving of power set of bleeding, it is low-pressure state in described gas and dust separating device, the air that indoor are entrained with dirt body is inhaled into outer cup 1 by the first air inlet 11, then interior cup 2 is entered into, particularly, region near top on described interior cup 2 sidewall is provided with opening 22, preferably offer breach at the edge, upper end of interior cup 2, like this, air-flow is in interior cup 2 in rotary course, the dirt body of larger particles just throws away from described opening 22 and falls into outer cup 1, then cyclonic air flow enters into air-guiding aisle by the filter bores 31 of filter element 3, then tornadotron 611 is entered into by pod apertures 51 and whirlwind inlet hole 612, described whirlwind inlet hole 612 is preferably arranged on the upper end near described tornadotron 611, because duct set 621 is inserted in described tornadotron 611, the length of described duct set 621 is less than the length of tornadotron 611, like this, air-flow is rotated down along the sidewall of tornadotron 61, density due to gas is less than the density of dirt body, therefore in the cyclone centrifugal rotation process of every one-level, air-flow up moves, dirt body down moves, the effect that gas dirt is separated can be reached, especially after multiple tornadotron internal cyclone filters, gas arrives the edge, lower end of duct set 621, the remarkable result that gas dirt is separated can be produced: in duct set 621, be provided with spoiler, air-flow is stoped to rotate in duct set 621, gas rises up into described duct set 621 in a low voltage state, finally discharge from the air outlet 71 of upper cover 7, then the cleaned air after filtering is discharged from described gas and dust separating device, enter into power set of bleeding to lower the temperature to motor, finally be drained into indoor, namely indoor gas has been purified, and the weight of dust is far longer than the weight of air, because air-flow stops the rotation in duct set 621, therefore dirt body cannot be followed air-flow rising and drop downwards, and dirt body enters into dust leg 42 by the dust-leaking hole 52 of tornadotron 611 bottom effectively.In order to strengthen the effect of cyclonic filter in interior cup, described second air inlet 21 is arranged on the sidewall bottom of interior cup 2.
Embodiment 2: the present embodiment is the more preferred embodiment on the basis of embodiment 1, with " offset bottom the lower end of the dust leg 42 of described control of dust funnel 4 and described interior cup 2 " in embodiment 1 unlike, the bottom of described interior cup 2 offers centre bore, the upper base surface of described outer cup 1 is provided with seal groove 12, the lower end of described dust leg 42 through described centre bore and holding the cell wall of described seal groove 12, the inwall in described Nei Bei 2 bottom centre hole and the outer wall of described dust leg are fitted.
Like this, not only greatly increase the appearance dirt volume of dust leg 42, and widened the distance of accommodating dirt body and duct set 621, accommodating dirt body is prevented again to be inhaled into duct set 621 and to enter motor, the lower end edge of structure to dust leg 42 of seal groove 12 is adopted to seal, turbulent flow can be prevented, in order to avoid other air-flows enter into dust leg 42 from the bottom of dust leg 42.
Embodiment 3: the present embodiment is the preferred embodiment on the basis of embodiment 1, described control of dust funnel 4 is concentric with dust leg 42, the edge of described control of dust funnel 4 is downward-sloping to dust leg 42 direction, namely the medial surface of described control of dust funnel 4 is the conical surface wide at the top and narrow at the bottom, and the dirt body dropped from dust-leaking hole 52 slides on the conical surface tilted in dust leg described in trend 42 body.Described dust leg 42 is arranged on the position, axis of interior cup 2, and dust leg 42 is the axis of flow rotation in interior cup 2, and dust leg 42 can not cause obstruction to swirling eddy.
Embodiment 4: on the basis of embodiment 1, in the present embodiment, each tornadotron 611 is cone structure, described tornadotron 611 is greater than one end internal diameter away from cyclone plate 61 on tornadotron 611 near one end internal diameter of cyclone plate 61, i.e. retracted downward; Described duct set 621 is similarly cone structure, described duct set 621 is greater than one end internal diameter away from air gathering plate 62 on duct set 621 near one end internal diameter of air gathering plate 62, i.e. retracted downward; Described duct set 621 is concentric with tornadotron 611, is conducive to dirt body like this and keeps the state be rotated down at a high speed to enter dust leg 42 until drop.
Except this, each tornadotron 611 adds the structure of lower inverted cone surface according to the upper face of cylinder, be then more excellent embodiment, can realize gas dirt rotating separation better.
Preferably, described tornadotron 611 corresponds to dust-leaking hole 52 distribution straggly, each tornadotron 611 is provided with two whirlwind inlet holes 612, described whirlwind inlet hole 612 is near cyclone plate 61, two whirlwind inlet holes 612 differ 180 °, a whirlwind inlet hole 612 is near described cyclone plate 61 center, another whirlwind inlet hole 612 is near the outward flange of described cyclone plate, in order to ensure intake velocity, air intake direction and tornadotron 611 upper edge of described whirlwind inlet hole 612 are tangent, and the air intake direction of rotation of two whirlwind inlet holes 612 is identical.
