Abstract
The utility model discloses an automatic dust collector for a blackboard eraser. The dust collector comprises a brush rod, a motor, an exhaust fan and a filter soft bag, wherein the brush rod is a hollow square pipe; brush bristles are arranged on one side surface of the brush rod; air suction holes are uniformly distributed in the walls at the periphery of the brush rod; the bottom of the brush rod is connected with a power output shaft of the motor; the brush rod is driven by the motor to rotate; an air inlet of the exhaust fan is connected with a bottom port of the brush rod through a soft pipe; and an air outlet of the exhaust fan is connected with the filter soft bag. When the dust collector is used, the brush bristles of the brush rod are contacted with a blackboard, the motor is fixed on one side at the bottom of the blackboard, the motor and the exhaust fan are started, the brush rod swings back and forth on the backboard, and chalk dust attached on the blackboard eraser is removed through the brush bristles, sucked in the brush rod through the air suction holes and sucked and collected in the filter soft bag through cooperation of the exhaust fan and the filter soft bag, so that the chalk dust is intensively removed, the pollution of the dust on the environment is avoided, and the problems that the blackboard cannot be cleaned and a large amount of raised dust is generated due to excessive dust in the using process of the blackboard are solved.
Description
Technical field
The utility model relates to a kind of teaching aid, relates in particular to a kind of propelling chalk brush dust catcher.
Background technology
After use, can accumulate more chalk dust due to blackboard eraser, these unnecessary chalk dusts can seriously hinder to cleaning effect next time when using, but except the play time, may carry out hardly in the class the cleaning of blackboard eraser.If reasonably do not solve, this will affect greatly on teacher and classmate's healthy generation, and sordid blackboard can affect the mood that teacher attends class.Becoming too much " hawk " because blackboard is attached makes classmates can't see clearly writing on blackboard.Experiment showed, that in the situation that the normal blackboard eraser that uses need clean blackboard eraser every day approximately 11 times, the course of upper 9 months an of academic year just needs altogether cleaning blackboard eraser 2970 times.So and this process is because airborne dust greatly can't be completed in the classroom.If have an absorber can allow this process in the classroom and can carry out any time, so will be quick, convenient many.
The utility model content
For above-mentioned the deficiencies in the prior art part, the utility model provides a kind of and can clean blackboard at any time, does not produce airborne dust, and propelling chalk is brushed dust catcher easily and efficiently.
In order to solve the problems of the technologies described above, the utility model has adopted following technical scheme:
Propelling chalk brush dust catcher, comprise the soft bag of brush holder support, motor, air exhauster and filtration, described brush holder support is the square tube of hollow structure, on one side of described brush holder support, bristle is set, the uniform suction hole that arranges on the surrounding wall of brush holder support, the bottom of brush holder support is connected with the power output shaft of motor and is rotated by motor-driven, and the air inlet of described air exhauster is connected with the bottom nozzle of brush holder support by flexible pipe, and the air outlet of air exhauster is connected with the soft bag of filtration.
the beneficial effects of the utility model are: when using this propelling chalk brush dust catcher, the bristle of brush holder support is contacted with blackboard, motor is fixed on bottom one side of blackboard, open motor and air exhauster, brush holder support swings back and forth on blackboard, brush by the chalk dust that bristle will be attached on blackboard eraser, and suck in brush holder support by suction hole, coordinate chalk dust is sucked and is collected in by air exhauster and the soft bag of filtration and filter in soft bag, make chalk dust concentrate cleaning, both avoided the pollution of dust to environment, reduce again blackboard in use because dust causes the problem that can't clean blackboard and a large amount of airborne dusts too much.
Description of drawings
Fig. 1 is the structural representation of propelling chalk brush dust catcher.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
As shown in Figure 1, propelling chalk brush dust catcher comprises brush holder support 1, motor 2, air exhauster 3 and filters soft bag 4.Brush holder support 1 is the square tube of hollow structure, on a side of brush holder support 1, bristle is set, the uniform suction hole 5 that arranges on the surrounding wall of brush holder support 1.The bottom of brush holder support 1 is connected with the power output shaft of motor 2 and is driven by motor 2 rotates, and the air inlet of air exhauster 3 is connected with the bottom nozzle of brush holder support 1 by flexible pipe 6, and the air outlet of air exhauster 3 is connected with the soft bag 4 of filtration.
when using this propelling chalk brush dust catcher, the bristle of brush holder support 1 is contacted with blackboard, motor 2 is fixedly mounted on bottom one side of blackboard, open motor 2 and air exhauster 3, brush holder support 1 swings back and forth on blackboard, brush by the chalk dust that bristle will be attached on blackboard eraser, and suck in brush holder support 1 by suction hole 5, coordinate chalk dust is sucked and is collected in by air exhauster 3 and the soft bag 4 of filtration and filter in soft bag 4, make chalk dust concentrate cleaning, both avoided the pollution of dust to environment, reduce again blackboard in use because dust causes the problem that can't clean blackboard and a large amount of airborne dusts too much.
Explanation is at last, above embodiment is only unrestricted in order to the technical solution of the utility model to be described, although with reference to preferred embodiment, the utility model is had been described in detail, those of ordinary skill in the art is to be understood that, can modify or be equal to replacement the technical solution of the utility model, and not breaking away from aim and the scope of technical solutions of the utility model, it all should be encompassed in the middle of claim scope of the present utility model.
