Air-out portion 200 still includes air-out pipe 240, and air-out pipe 240 and cartridge filter 210 integrated into one piece, the inside of air-out pipe 240 is main exhaust duct 241, is provided with a plurality of air-out breachs 214 along the circumferencial direction equipartition on the interior bottom plate of cartridge filter 210, and air-out breach 214 is located the outside of filter screen 211 and communicates the inside main exhaust duct 241 of air-out pipe 240. An air outlet impeller 220 is arranged inside the air outlet duct 240, and a total air outlet 230 is arranged at the lower end of the air outlet duct 240.
The following, in conjunction with the above-described embodiments, will describe the principles and operation of the present invention in detail:
the initial guide plate 410 is horizontal, the wind guide mechanism 300 does not rotate, and the passive impeller 360, the active impeller 370 and the universal shaft 380 do not rotate.
The air inlet impeller 120 is started to rotate and the air outlet impeller 220 is started, the air inlet impeller 120 sucks external air flow into the filtering component from the main air inlet 110, the external air flow enters the positioning cylinder, contacts the filter screen 211 through the air passing notch 311 on the inner wall 310 of the positioning cylinder, enters the exhaust duct from the air passing notch 311 on the outer wall 320 of the positioning cylinder after being filtered by the filter screen 211 and flows out from the air guide outlet 332, and finally enters the air outlet pipeline through the air outlet notch 214 under the suction action of the air outlet impeller 220 and flows out of the outside. The inlet air is air containing particles, and the outlet air is clean air.
When the airflow flows out of the air guide outlet 332, the driving impeller 370 is driven to rotate, and the driving impeller 370 drives the driven impeller 360 to rotate through the universal shaft 380. The passive impeller 360 sucks a part of the airflow flowing out of the air guide outlet 332 into the air draft duct 340, and further performs reverse side blow on the filter screen 211, so that impurities at a position on the filter screen 211, which is shielded by the inner wall 310 of the positioning cylinder, fall below the filter screen 211, fall into the dust collection tray 216 through the guide ring 215, and are collected there. Meanwhile, the wind guide mechanism 300 is driven by the reaction force of the wind flowing out of the wind guide outlet 332 (along the tangential direction of the positioning cylinder), the filter screen 211 is uniformly cleaned in the rotating process of the wind guide mechanism 300, and when dust particles are accumulated to a certain degree, the dust can jack the support base plate 350 up for continuous collection.
When the wind guiding mechanism 300 rotates until the wedge 430 corresponds to the convex column 212, the wedge 430 slides inwards under the extrusion of the convex column 212 to jack the guide plate 410 and the synchronous rod 420, that is, the guide plate 410 guides the wind flowing out from the wind guiding outlet 332 upwards, the tangential force of the airflow is reduced, the rotating speed of the wind guiding mechanism 300 is reduced, so that the outer concave part of the filter screen 211 is impacted by the airflow for a longer time, and the dust at the corresponding position is blown off more easily. After the guiding plate 410 guides the airflow at the air guiding outlet 332 upwards, the whole air guiding mechanism 300 is subjected to a downward reaction force, and the downward reaction force of the air guiding mechanism 300 drives the supporting bottom plate 350 to compact the dust downwards, so that the dust is prevented from being taken away again by the wind.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
