Abstract

The utility model discloses an eraser power collector, which is characterized in that: a cavity at the upper part of a shell is provided with a post brush whose shaft is provided with a rocking handle at one end, and the inner face of a shell cover corresponding to the post brush is provided with a brush body rotating drum; the lower part of the shell is provided with a dust retainer, and two ends corresponding to a dust opening at the upper part are provided with a rotating rod for connecting an dust stop door; the rotating rod is sleeved with a torsion spring. When in use, placing the blackboard brush with dust at the post brush, and swaying laterally the post brush, under the action of the post brush and the brush body rotating drum, the dust in the blackboard bristle falls in the dust retainer; when the dust retainer is pulled out to be cleaned, the dust opening is closed automatically by the stop door. The utility model has professional structure, prevents effectively the dust from escaping, and is economic and practical.

Description

Blackboard brush shedding gatherer

The utility model relates to a kind of cleaning device, particularly a kind of blackboard brush shedding gatherer.

At present, the cleaning of dust on the blackboard brush is not also had special implement, just take to beat the way of coming off, the dust that comes off flies upward everywhere, contaminated air, harmful health.

The purpose of this utility model is in order to overcome above-mentioned weak point, and provides a kind of rational in infrastructure, and is easy to use, can prevent the blackboard brush shedding gatherer that dust leaks effectively.

The purpose of this utility model is achieved in that blackboard brush shedding gatherer comprises shell, it is characterized in that shell upper is divided into cylindrical shape, end face has cap, the cap inner face is equipped with brush body motion rotating cylinder, there is down prominent retaining brush limit on the shell nozzle two axial limits of corresponding cap, outer casing underpart is divided into the hollow trapezoidal shape, the ash port place of its inner corresponding top cylinder is fitted with flue-dust retainer, corresponding flue-dust retainer the inside, ash port is equipped with a dwang in limit, outer casing underpart branch two ends longitudinally, the long limit face arm of angle of L shaped dust falling stop door is fixed on the dwang, its long limit face is consistent with ash port, the width of minor face face guarantees that when flue-dust retainer advances its end limit leans on outside, flue-dust retainer the inside, is with a torsionspring on the dwang, spring one end is stuck on the cylinder outer wall at ash port place, and the other end is stuck on the horizontal end outside of falling stop door.The post that is placed with oblique arrangement shape bristle in shell upper is divided is brushed, and the post brush axle that has rocking handle passes the installation rotation hole of shell upper cylinder one end face, post brush center hole, cylinder other end successively, and the post brush is brushed between the axle with post and fixedlyed connected by pin.

Fig. 1 is the utility model structural representation;

Fig. 2 is the utility model cross-sectional end view;

Fig. 3 is falling stop door, dwang connection diagram.

Now illustrated embodiment is made detailed description to the utility model in conjunction with the accompanying drawings.

Blackboard brush shedding gatherer comprises shell 1, shell 1 top is divided into cylindrical shape, end face has cap 2, cap 2 inner faces are equipped with brush body motion rotating cylinder 3, there is down prominent retaining brush limit 4 on the shell nozzle two axial limits of corresponding cap, shell 1 bottom is divided into the hollow trapezoidal shape, the ash port place of its inner corresponding top cylinder is fitted with flue-dust retainer 5, corresponding flue-dust retainer 5 the insides, ash port limit, outer casing underpart branch two ends longitudinally is equipped with a dwang 6, the long limit face arm of angle of L shaped dust falling stop door 7 is fixed on the dwang 6, its long limit face is consistent with ash port, the width of minor face face guarantees that when flue-dust retainer 5 advanced, its end limit leaned on outside, flue-dust retainer 5 the insides, is with a torsionspring 8 on the dwang 6, spring one end is stuck on the cylinder outer wall at ash port place, and the other end is stuck on the horizontal end outside of falling stop door 7.Be placed with the post brush 9 of oblique arrangement shape bristle in shell 1 top, the post brush axle 10 that has rocking handle passes shell upper cylinder one end face successively, post is brushed the installation rotation hole of 9 center holes, cylinder other end, and post brush 9 is brushed between the axle 10 with post and fixedlyed connected by pin.

The utility model is owing to adopt above design, during use, will be with the blackboard brush of dirt to place post to brush, brush finish be downward, the brush body dual-side is between retaining brush limit, cover cap, brush body motion rotating cylinder roof pressure brush body, the left and right post brush that shakes, under the acting in conjunction of post brush and brush body motion rotating cylinder, dust in the blackboard bristle is come off in the flue-dust retainer, and the dust of collection is reproducible utilization also, economizes on resources.When flue-dust retainer was pulled out cleaning, because the effect of torsionspring, the long limit face of falling stop door prevented that automatically with the ash port capping dust from falling into outer casing underpart, and when flue-dust retainer was advanced, its inside face was answered back to falling stop door minor face face and ash port is opened.Rational in infrastructure, easy to use, prevented that effectively dust from leaking, economical and practical.
