Fig. 6 be among Fig. 3 I-I ' to cutaway view.Below with reference to Fig. 6 the internal structure and the course of work thereof of dust collect plant 400 are elaborated.As shown in Figure 5, dust collect plant 400 provided by the invention comprises: control of dust body 406; The case sealing 402,415 that can selectivity seals up control of dust body 406 downsides; Be installed in the inside of control of dust body 406, can improve the conical strainer 405 of dust catching efficiency; Can prevent the blocking-up portion 404 of the scattering foreign matter that deposits; Can slow down the flow velocity of cyclonic air flow, foreign matter be sunk, and can prevent the anti-flow plate 403 that dust floats; Be arranged on the upside of control of dust body 406, can make the mobile exhaust portion 407 smoothly of air of discharging from control of dust body 406; The air that can make the exhaust portion 407 of flowing through is along the mobile spacer portion 408 of a certain direction; With the cap assemblies 409,410,411,412 that is arranged on exhaust portion 407 upsides.Describe the formation of control of dust body 406 below in detail.Described control of dust body 406 is provided with a plurality of walls that vertically extend and form, and comprises being arranged on outermost outer wall 418; Be positioned at the midfeather 419 of outer wall 418 inboards; With the inwall 420 that is positioned at midfeather 419 inboards.Described midfeather 419 and inwall 420 are not arranged in the zone that dust collect plant air entry 401 occupies, and can make flowing of air more smooth and easy thus.Space between outer wall 418 and the midfeather 419 constitutes the first foreign matter storage bin 416; Space between midfeather 419 and the inwall 420 constitutes the second foreign matter storage bin 417, and the inner space of inwall 420 then constitutes the first foreign matter separator box 423.But, the concrete user mode of dust collect plant 400 not simultaneously, the purposes in these spaces is difference to some extent.

Being benchmark with the sequence of flow of air below is elaborated to the effect and the course of work of above-mentioned parts.At first, air is by the inside of dust collect plant air entry 401 inflow dust collection devices 400.Wherein, the outside of dust collect plant air entry 401 contacts with front end support 170, and its inboard then is connected with the first foreign matter separator box 423, extraneous air can be sucked thus.In the inboard of dust collect plant air entry 401, from inwall 420 to the inside direction protrude and to be formed with first and to flow into guide part 421, thereby air can be guided into the inner peripheral surface of the first foreign matter separator box 423.The air that enters the first foreign matter separator box, 423 inside can make foreign matter sink in the process that is rotated, and the air that is purified is then upwards discharged by the perforate of conical strainer 405.Using the reason of conical strainer 405 at this is because dust collect plant air entry 401 is positioned at upside, therefore can produce the cyclonic air flow of fair speed on the top of conical strainer 405, and produces the cyclonic air flow than low velocity in its underpart.Promptly, foreign matter can be rotated on the position in the more close outside in the cyclonic air flow of fair speed, foreign matter then can be rotated near inboard position in than the cyclonic air flow of low velocity, therefore in order to remove foreign matter more effectively, preferably filter is designed to cone shape.Conical strainer 405 is installed in the centre of demarcation strip 437, and demarcation strip 437 then constitutes the upper wall of the first foreign matter separator box 423.Conical strainer 405 also can be designed to be able to the structure that disassembles from demarcation strip 437, and is formed with a plurality of perforates on it, thereby extraneous air can pass perforate to its inner inflow.At this, for the foreign matter that prevents to fall disperses once more, be provided with blocking-up portion 404 at the downside of conical strainer 405, as shown in Figure 6, more down its diameter is big more in described blocking-up portion 404, so just can prevent that foreign matter from dispersing once more.The below of blocking-up portion 404 is formed with the anti-flow plate 403 of an apart determining deviation, and it can prevent that the foreign matter that deposited is under the influence of cyclonic air flow and the phenomenon of floating once more.In addition, isolated foreign matter will be stored into the first foreign matter storage bin 416 that is positioned at below it in the first foreign matter separator box 423.At this,, be provided with first case sealing 415 in the lower end of the first foreign matter storage bin 416 for leaking appears in the foreign matter that prevents to store.In addition, isolated bigger foreign matter to demarcation strip 437 upside leaked-in airs, but also needed to utilize once more cyclonic air flow to isolate small foreign body by conical strainer 405.Below back one process is elaborated.The air of conical strainer 405 of flowing through will flow into the inside that guide part 422 flow into a plurality of second foreign matter separator boxs 424 by second.In addition, because the second inflow guide part 422 is tangential on the inner peripheral surface of the second foreign matter separator box 424, the air portion's generation within it that therefore flows into the second foreign matter separator box 424 rotatablely moves.The isolated foreign matter of inner utilization cyclonic air flow at the second foreign matter separator box 424 will fall to the bottom, and be stored in the second foreign matter storage bin 417.For the foreign matter that prevents to have sunk disperses once more, the diameter of the second foreign matter separator box, 424 downsides dwindles gradually.And, for the foreign matter that prevents to be deposited in the second foreign matter storage bin 417 leakage occurs and is provided with second case sealing 402 at its downside.At this, described second case sealing 402 utilizes shaft-like attaching parts to be connected with first case sealing 415, its objective is the internal capacity that increases the first foreign matter storage bin 416.In other words, owing to need in the space between the upper end of first case sealing 415, store more foreign matter as far as possible, preferably use the less rod-like members that takes up space that both are interconnected in the lower end of second case sealing 402.To flow into the inside of exhaust portion 407 through air entry 425 after the air separation that enters the second foreign matter separator box, 424 inside goes out foreign matter, and accumulate in the space between exhaust portion 407 and the spacer portion 408.At this, the diameter of air entry 425 is less than the internal diameter of the second foreign matter separator box 424, can obviously reduce the possibility that the second foreign matter separator box, 424 interior foreign matters flow to exhaust portion 407 like this.In other words, the foreign matter that is deposited on the second foreign matter separator box, 424 inside can not pass through air entry 425 outflows.As mentioned above, will be through the air that two place's cyclonic air flows purify by motor air entry 172 flow direction motors, then, the air of the motor of flowing through will be discharged from the rear of vacuum cleaner body 100.In addition, the upside of spacer portion 408 also is provided with and covers 200.Specifically, described lid 200 comprises: constitute first lid 410 that covers agent structure; Be separately positioned on the 3rd lid 412 and second lid 409 at first lid 410 front portions and rear portion; With first lid 410 and second can be covered the 409 lid plug-in units 411 that are fixed together.

Fig. 7 is a vacuum cleaner body vertical structure cutaway view provided by the invention.Below with reference to Fig. 7 the course of work of dust collect plant 400 and vacuum cleaner body 100 is elaborated.As shown in Figure 7, at first extraneous air enters the inside of vacuum cleaner body 100 by the body air entry 171 that is connected with connector 6, and the inside by dust collect plant air entry 401 inflow dust collection devices 400, the cleaned air behind the separating out foreign objects of the inside of dust collect plant 400 will be by the inside of motor air entry 172 inflow motor frames 300.In addition, motor air entry 172 is horizontally placed on the top of vacuum cleaner, and the air of the dust collect plant 400 of therefore flowing through flows into from horizontal direction.At this moment, motor frame 300 vertically is provided with inner motor, therefore reduced vacuum cleaner inside motor frame 300 the space is set.That is, motor frame 300 is set, motor frame 300 is set, reduced the space that motor frame 300 occupies in vacuum cleaner inside, thereby reduced the volume of vacuum cleaner on the whole along vertical direction with respect to along continuous straight runs.In addition, motor frame 300 is set vertically, and air is because the exhaust outlet of dust collect plant 400 is arranged on top from the top inflow.The top that the exhaust outlet of dust collect plant 400 is arranged on dust collect plant 400 is because the air of inflow dust collection device 400 inside should be discharged by dust collect plant 400 after the 1st foreign matter separator box 423 and the 2nd foreign matter separator box 424 are flowed through in inside, and below dust collect plant 400, need to be provided with the bigger foreign matter storage bin 416,417 in space.In addition, vertically bending the back from motor air entry 172 leaked-in airs according to the arrangement states of motor frame 300 flows into downwards.In other words, flow through dust collect plant 400 after the vertical bending of horizontal direction leaked-in air, flow downward towards the air entry of motor frame 300.At this moment, can also provide certain converter plant that airflow direction is become vertical direction from the horizontal direction bending at the rear portion of motor air entry 172.The air that flows downward from the top towards motor frame 300 is discharged to the outside by the body exhaust outlet 302 that is arranged on vacuum cleaner body 100 back sides after the motor frame 300 of flowing through.
