In a kind of cleaning vacuum plant known by WO99/65376, base plate have in the both sides of suction opening for cleaning purpose the horizontal component that slides on the ground.This embodiment also is the dust that can not exhaust effectively.
In above-mentioned known embodiment, roller is installed in preposition place in the housing, can not carry out vertical compensating motion.This is disadvantageous when cleaning vacuum plant is used in very uneven mulching material.The mulching material of pluse cloth has very big resistance to roller, thereby has turbine not have the next danger with enough speed drive rollers of sufficient power.
Summary of the invention
The objective of the invention is, a kind of vacuum cleaner with the described structure of preface is provided, it is at the work dust that the time can exhaust well, and both can be used for the mulching material that smooth earth also can be used for pluse cloth.
By the present invention, in the cleaning vacuum plant of pressing the described structure structure of preface, above-mentioned purpose is utilized following feature to make up and is realized:
A) above-mentioned base plate has a swabbing action face that is defined by a rubber lip that leans against on the ground at the rear portion, this acting surface is wedge shape in the place ahead of suction opening, and has a ladder return pulley exterior feature at the rear of suction opening, this ladder return pulley exterior feature comprises a horizontal component and the adjacent recesses with inclined-plane of giving prominence to and form the back edge of suction opening downwards;
B) above-mentioned suction opening by the width that distance limited between two parallel edges between the 23mm to 27mm, narrow rib is located at its end, and extends on the part of the width of suction opening, with the air-flow that reduces to enter in the edge;
C) the swabbing action identity distance height overhead of base plate measuring between the 1.4mm to 2.0mm at above-mentioned suction opening along the place;
D) above-mentioned roller is provided with bristle, and be installed in can be on the rocking arm of axis rotation, and above-mentioned axis is parallel to the rearward end that turbine is positioned at dust collecter.
Near the effect of the swabbing action face of constructing suction opening by the present invention is, air is with the downside suction of high velocity air along above-mentioned edge, and dust granule is exhausted by air-flow and taken away effectively.By above-mentioned feature b) suction opening of design can clean the ground near metope effectively.By above-mentioned feature d of the present invention) because roller is installed on the rocking arm, so the resistance of the roller of rotation is only depended on slightly the character of mulching material.This makes that the mulching material of smooth earth and pluse cloth all can effectively be cleaned.
In a preferred embodiment of the invention, above-mentioned swabbing action identity distance height overhead is 1.7 ± 0.3mm.Advantageously, above-mentioned back is along having the rounding that radius is 1.0-1.5mm towards suction opening.Further advantageously, the wide recessed at least 3mm in edge of suction opening relatively of the ladder return pulley of above-mentioned swabbing action face, formed recess is defined by rubber lip.The edge is preferably 4 mm wides after the level of above-mentioned suction opening.Inclined-plane after the above-mentioned level between edge and the recess has the cutting-out angle of inclination of 30-40 degree.
By a preferred embodiment of the present invention, above-mentioned turbine is Pierre's formula turbine that pauses, and the air stream that enters in the turbine room tangentially flows into turbine room basically.
