Description
Technical field
The utility model relates to blackboard eraser, particularly relates to a kind of eraser with support bar.
Background technology
Blackboard right and wrong educational aid usually, teacher by writing the content of courses to reach the object of education student on blackboard with chalk.The word that writes with chalk can cause a lot of chalk dust, uses blackboard eraser to have a lot of chalk dust when erasing the board and to wave contaminated environment and descending slowly and lightly on the body of teacher, student, the clothing and be exposed to outer hair, skin made dirty.Also do not have blackboard eraser can reduce the problem of waving of chalk dust now.
Another shortcoming of existing blackboard eraser is, the height of pupil is often not high enough, often can reach the eminence of blackboard when erasing the board, and common way steps down on stool to erase the board, and this mode erased the board often can be caused danger.
Utility model content
For above-mentioned technical problem, the utility model provides a kind of eraser with support bar, realizes dust suction effect of blackboard eraser by blackboard eraser being arranged the parts such as vacuum chamber and mini-fan, reaches the object absorbing chalk dust.
In order to realize above-mentioned technical purpose, the utility model adopts following technical scheme:
A kind of eraser with support bar, it is made up of blackboard eraser body and bristle, blackboard eraser body has hollow cavity, described hollow cavity is divided into vacuum chamber and battery cavities by dividing plate, be provided with miniature dust absorption fan in vacuum chamber, bristle installs the backplate surface in blackboard eraser body, is provided with dust hole between bristle gap, miniature dust absorption fan is power supply with battery, and the side of dust-absorbing box is provided with ash discarding mouth; Also comprise piezoelectricity induction installation and a microcomputer controller, described piezoelectricity induction installation comprises and is arranged on piezoelectric transducer between hairbrush and blackboard eraser body, and described piezoelectric transducer is connected with microcomputer controller, microcomputer controller and dust-absorbing fan control connection; Also comprise telescopic rod and fixed mount, the back side of described dust-absorbing box is fixed with described fixed mount, and described fixed mount is connected with described telescopic rod.
Described microcomputer controller is arranged in described battery cavities.
A backing plate is also provided with between described piezoelectric transducer and described blackboard eraser body.
Described blackboard eraser body upper surface is provided with the switch of opening or closing described miniature dust absorption fan.
Described bristle is that synthetic material is made.
Described switch is connected with power circuit.
Described power supply is battery.
The beneficial effect of a kind of eraser with support bar of the utility model:
The utility model eraser with support bar; structure is simple; reasonable in design; be skillfully constructed, it is creatively provided with micro-machine in blackboard eraser, focuses in the cavity of the chalk dust suction blackboard eraser driving fan blade wiping to be got off; doing so avoids the situation generation that chalk dust when erasing the board flies upward everywhere; protect the healthy of Faculty and Students, also ensure the environmental sanitation in classroom, for cleaning person reduces the amount of labour simultaneously.
Be connected with a telescopic rod at the back of blackboard eraser body, make the not high classmate of height also can clip any angle of blackboard very easily; And its making is simple, with low cost, be suitable for applying in the art, possessed market prospects widely.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Wherein, 1 is blackboard eraser body, and 2 is dust-absorbing box, and 3 is bristle, and 4 is miniature dust absorption fan, and 5 is ash discarding mouth, and 6 is switch, and 7 is battery case; 8, telescopic rod; 9, fixed mount.
