The specific embodiment

Fig. 1 is extremely shown in Figure 3 to be the embodiment of product of the present invention.As shown in the figure, this dirt cup comprises dirt cup housing 13, be located at the tangent with it dirt cup air inlet 1 of dirt cup housing 13 perisporiums, be opened in bowl cover that housing covers mutually on dirt cup air outlet 3 and place separator in the dirt cup, separator is provided with air inlet 6, the centre bit of the horizontal level at separator air inlet top and dirt cup air inlet is equipped with certain drop height, the below of separator air inlet 6 is provided with cage 7, the air inlet 6 of separator communicates with dirt cup air inlet 1, and the outer tube of separator links to each other with dirt cup housing.Described separator air inlet top is connected with two coaxial interior pipes and

outer tube

8,9, and the bottom is connected with the cage 7 of truncated cone-shaped.In pipe 8 outer walls is connected with the bottom lock of outer tube 9 inwalls, wherein interiorly manages 8 and communicate, and interior pipe 8 is shorter than outer tube 9 with dirt cup air outlet 3.Interior pipe 8 extends through cage 7 downwards.Have one to connect support 4 in the dirt cup, it is held on the dirt cup rim of a cup after being connected in separator outer tube 9 upper ends in the bayonet socket mode.It is suitable for reading big down young tubaeform that this connection support 4 is, and support 4 has centre bore 10, and the centre bore below connects a short tube 11 corresponding with interior pipe 8, and the short tube diameter is slightly less than interior pipe.As shown in Figure 2, separator air inlet 6 is body in the form of a ring, it is to rotate uniform arrangement by screw-like rotation arrangement or a plurality of flight by the multiple thread shape by a flight 12 to form, the sealing link of pipe and outer tube bottom in the upper end of flight 12 is connected in, the other end is fixed on truncated cone-shaped cage 7 and the extension 14.Cage below connect one with extension coaxial and diameter leaves a gap greater than the cylindrical cavity 16 of extension between extension and the cylindrical cavity.Unimpeded in order to the air-flow that enters flight 12.The lower end of the flight 12 of the air inlet 6 uniform arrangements of described separator is passed cage 7 and is returned with backspin and stretch.The conic tube 17 of one bottom opening is set in cylindrical cavity 16.The upper edge of conic tube 17 is connected with cylindrical cavity 16 in the horizontal position that is lower than extension 14 lower ends, between the bottom of the lower edge of conic tube 17 and cylindrical cavity 16 certain interval is arranged.The helical structure 19 of one or three leaf revolving fragments is set in the described extension 14.

Narrate the operation principle that the present invention separates for three times below in conjunction with Fig. 1, Fig. 2 and Fig. 3.The air channel that connects the electric fan air inlet in the dust catcher is connected with dirt cup air outlet 3, starting switch, after the electric fan work, dirt cup inner chamber produces negative pressure, the air that has dust enters dirt cup inner chamber by dirt cup air inlet 1, because the periphery of dirt cup air inlet 1 axis and dirt cup shell 13 is tangent, thereby produce swirling eddy.Owing to being lower than dirt cup air inlet 1, separator air inlet 6 positions have certain drop again, make the certain draught head of generation between two air inlets, therefore after the air that has a dust enters the dirt cup, promptly produce the quick whirlwind of downward spiral, dust is subjected to centrifugal action to be thrown toward perisporium and along fall dust-collecting cavity 2 between dirt cup cup 13 and outer tube 9 of wall rotation.Because the partition effect of cage 7, the dust that falls into dust-collecting cavity 2 are difficult to be subjected to the influence of top spiral air flow and roll again and enter separator air inlet 6.Isolate most dusts, the air of slightly a small amount of thin dirt enters gap 15 between extension 14 and the cylindrical cavity 16 by separator ring-type air inlet 6.Owing to be subjected to being distributed in the guide effect of the flight 12 of air inlet, the air that enters slightly a small amount of thin dirt in the gap 15 produces spiral air flow equally.When this part air drops to extension 14 lower ends, because action of centrifugal force enters the thin dirt in gap and tangentially is rotated down the inner chamber 18 that enters cartridge type cavity 16 at the inwall of conic tube 17, and the air after separating manages 8 in extension 14 upwards enters.Because the air after the effect of three leaf conveyor screws 19 in the extension 14 separates upwards continues rotation, as the also slightly a small amount of thin dirt of this part air, then pipe 8 upper end rear screw radiuses increase suddenly in this part air rises to, blast reduces, centrifugal force will mix once more in the thin dirt of airborne minute quantity and separate, and get rid of to outer tube 9 inwalls and along the wall rotation and fall to interior dirt chamber 5.Short tube 11 guiding of air after separating for three times on support 4 enter electric fan by dirt cup air outlet 3, discharge dust catcher then.
