Abstract
The utility model discloses a dust absorbingblackboard eraser, which comprises a blackboard eraser body and a cleaning rag covered on the surface of the blackboard eraser body, the clearance is reserved in the cleaning rag, a motor with a power source circuit is mounted in the blackboard eraser body, blades are arranged on the motor, and a grab handle is connected on the blackboard eraser body. By adopting the structure, the blackboard eraser can absorb the produced dust due to the suction force generated by the driving of the motor to the blades, thereby avoiding the waste of resources and avoiding the injury to the human body caused by the dust of chalk. Besides, the blackboard eraser is provided with the grab handle, which is convenient for use.
Description
Technical field:
The utility model relates to a kind of blackboard eraser, relates in particular to a kind ofly the dust that produces can not be descended slowly and lightly and can take the blackboard eraser of holding more like a cork.
Background technology:
At present, known blackboard eraser can produce many tiny dust after having wiped chalk, flies away in air the respiratory health of the academics and students around the influence.And be unfavorable for the saving of resource, cause waste.And moulding is unfavorable for taking holds, and in use slips out of the hand easily, brings inconvenience.
The utility model content:
The purpose of this utility model is: provide a kind of and the dust that produces can not be descended slowly and lightly and can take the blackboard eraser of holding more like a cork, with overcome existing blackboard eraser cannot the dustproof drawback with take the deficiency of holding inconvenience.
In order to reach described purpose, the technical solution adopted in the utility model is: dust absorption blackboard eraser, comprise blackboard eraser body and the wiper that covers the blackboard eraser body surface, it is characterized in that: leave the gap between described wiper, the blackboard eraser body interior is equipped with the motor of charged resource loop, motor is provided with blade, is connected with lever on the blackboard eraser body.
Preferably, also be provided with filter screen in the described wiper.Such structure can avoid some oarse-grained chalk fragments to sneak into influences result of use in the blackboard eraser.
Preferably, be provided with dust storage portion in the blackboard eraser body.Such structure can store dust, does not pollute the environment on the one hand, can reclaim on the other hand once more and utilize, and plays effect in energy saving and environmental protection.
Preferably, described lever is the L type.Such structure is more convenient for holding with a firm grip, in use can not drop.
Owing to adopted described technical scheme, the utility model can drive blade by motor and produce the dust that suction holds generation, prevents the waste of resource, prevents the human injury that the dust because of chalk causes, it is easy to use to be provided with lever simultaneously.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified:
Fig. 1 is the internal structure schematic diagram of the utility model dust absorption blackboard eraser.
The specific embodiment:
As shown in Figure 1, the utility model dust absorption blackboard eraser comprises blackboard eraser body 1 and covers the wiper 6 on blackboard eraser body 1 surface that leave gap 5 in the described wiper 6, blackboard eraser body 1 inside is equipped with the motor 2 of charged resource loop 3, motor is provided with blade 4, is connected with lever 7 on the blackboard eraser body 1.Also be provided with filter screen in the described wiper 6.Be provided with dust storage portion 8 in the blackboard eraser body 1.
Described lever 7 is the L type.
The utility model is installed a motor 2 in blackboard eraser body 1 inside, and is connected with the electric power loop 3 that power is provided for it.When erasing the board, hold lever 7, connect circuit again, make motor 2 work, rotate, reduce the pressure of blackboard eraser body 1 inside, produce one inside air-flow thereby drive blade 4.Thereby allow dust be sucked into the principle of interior dust catcher, reach the purpose that reduces dust.Corresponding with it, the structure of blackboard eraser body 1 also corresponding variation will take place: the wiper 6 of blackboard eraser will leave certain space 5, makes dust pass through.Also be provided with filter screen in the wiper 6 simultaneously, enter, motor 2 is brought infringement to avoid bigger chalk particle.Be provided with dust storage portion 8 in the blackboard eraser body 1, can concentrate dust.
Through initial estimate, behind use the utility model dust absorption blackboard eraser, the amount of dust descends 60% in the back air that erases the board.These dust exist in the dust storage portion 8 simultaneously, are easy to be recovered utilization, continue the creation of value.Brought good effect.
