The present invention is described in further detail below in conjunction with the accompanying drawings and the specific embodiments.
As it is shown in figure 1, Fig. 1 illustrates the schematic diagram of the cleaner of the embodiment of the present invention.This cleaner includes the first cylinder 1 being vertically arranged, and this first cylinder 1 top has air outlet；This first cylinder 1 bottom end closure, so that forming the holding tank for holding dedusting liquid bottom the first cylinder 1；Wherein, different according to the chemical composition of dust, dedusting liquid can be water, faintly acid saline, weak acid, alkalescence saline or weak base etc..
This first cylinder 1 inwall protrudes and is formed with collar flange 11, being positioned on the wall below flange 11 and offer air inlet 12 of this first cylinder 1.This air inlet 12 can have 1, it is also possible to is multiple.
Cleaner also includes piston 2, and this piston 2 includes the second cylinder 22 being slidably disposed in collar flange 11, turns up and form the ring-type limiting section 23 being supported on collar flange 11 separably in this second cylinder 22 top；When ring-type limiting section 23 is supported on collar flange 11, just very close to each other between collar flange 11 and piston 2；
Cleaner also includes being arranged on the second cylinder 22 inside and occupying the drainage screen 4 in the internal whole cross section of this second cylinder 22；Being positioned on the wall below drainage screen 4 and offer through hole 21 of second cylinder 22；Here, through hole 21 can arrange 1, it is also possible to arranges multiple；Preferably, through hole 21 has multiple, and multiple through hole 21 is on average distributed on the wall of the second cylinder 22 circumferentially.When piston 2 upward sliding, when making ring-type limiting section 23 separate with collar flange 11, gap between piston 2 and collar flange 11, can be produced；When piston 2 continues to slide up, so that when through hole 21 is in the top of collar flange 11, the first cylinder 1 be positioned at being positioned at the space below collar flange 11 and just can passing through through hole 21 and effectively connect of space above collar flange 11 and the first cylinder 1.
Cleaner also includes being arranged in the first cylinder 1 top inner wall, for producing the fan component 8 of the air-flow flowed to air outlet by air inlet 12 inside the first cylinder 1；What cleaner also included being arranged on the first cylinder 1 is positioned on the inwall below collar flange 11, for monitoring the displacement transducer 9 of the slide displacement of piston 2；
