Abstract
A kind of ash-collecting blackboard eraser, comprise housing and blackboard rubbing head, it is characterized in that: described housing is indent channel-shaped, battery and motor are installed in groove, described motor shaft is installed with small-sized fans, the base plate of described blackboard rubbing head and housing socket connection, described blackboard rubbing head base plate is provided with aperture, and described aperture communicates with fan; Fan and battery, by the improvement to existing structure, are arranged in groove and collect chalk dust, avoid the impact of flying upward the health on wiper of chalk dust by the utility model, and this structure is simply easy to make.
Description
Technical field
The utility model relates to a kind of realia, particularly relates to a kind of practical ash-collecting blackboard eraser.
Background technology
Existing blackboard is all generally cuboid one piece of plate body, then the placement section that is placed blackboard eraser is installed in below, but be lime because teacher writes chalk main component used, in blackboard wiping process, chalk dust can fly upward everywhere along with in the process of wiping, because blackboard is higher, when erasing the board, all to face upward headrest pin, the chalk dust flown upward to be easy to suck by human body, this can bring harm to the person, affects the person healthy.Beyond thought harm can be brought to wiper for a long time in the past, and therefore, be necessary just to improve for this present situation, make wiper from such misery.
Summary of the invention
For above problem, the utility model provides a kind of ash-collecting blackboard eraser, has and chalk dust can not be allowed everywhere to fly away along with the movement of blackboard eraser when blackboard wiping, avoid the misery of the dust suction of blackboard wiping, decrease the harm brought people.
A kind of ash-collecting blackboard eraser, comprise housing and blackboard rubbing head, it is characterized in that: described housing is indent channel-shaped, battery and motor are installed in groove, the axle of described motor is installed with small-sized fans, the base plate of described blackboard rubbing head and housing socket connection, described blackboard rubbing head base plate is provided with aperture, and described aperture communicates with fan.This structure by arranging the fan with dust suction in blackboard eraser housing, the opening switch when blackboard wiping, makes fan produce suction, produces attraction by aperture to the chalk dust of blackboard rubbing head, thus avoid flying upward of chalk dust, alleviate misery and the harm of wiper.
Further, the sidewall of described housing is provided with switch, described switch one end connects battery, and one end connects motor, and by electric wire, motor is connected with battery again, forms loop.This structure, by switch-linear hybrid, is convenient to the switch controlling blackboard eraser, avoiding allowing when not using electric motor fan work, avoiding the shortcoming of waste electricity.
Further, the sidewall of described housing is provided with square aperture, the base plate of described blackboard rubbing head is provided with the corresponding plug of square aperture, and described plug tip is provided with little barb.This structure is convenient to dismounting housing and blackboard rubbing head, is also convenient to the chalk dust in inspiration groove to pour out simultaneously.
Further, a dust-absorbing box is outside equipped with at described motor and battery.Motor and battery and chalk dust are kept apart by arranging dust-absorbing box, fan, by chalk dust inspiration dust-absorbing box, avoids chalk dust and adheres on battery and motor, avoids the damage of chalk dust to battery and motor.
beneficial effect:
Fan and battery, by the improvement to existing structure, are arranged in groove and collect chalk dust, avoid the impact of flying upward wiper's health of chalk dust by the utility model, and this structure is simply easy to make.
Accompanying drawing explanation
Fig. 1 is the structural representation in the utility model middle shell;
Fig. 2 is the front view of the utility model blackboard eraser;
Fig. 3 is the structural representation of barb on blackboard rubbing head base plate in the utility model.
Detailed description of the invention
Below in conjunction with embodiment and accompanying drawing, the utility model is described in further detail.
As shown in Figure 1, 2, a kind of ash-collecting blackboard eraser, comprise housing 1 and blackboard rubbing head 5, it is characterized in that: described housing 1 is in indent channel-shaped, battery 3 and motor 8 are installed in groove, described motor shaft 9 is installed with small-sized fans 2, the base plate of described blackboard rubbing head and housing socket connection, described blackboard rubbing head base plate is provided with aperture 6, described aperture communicates with fan 2, and described battery and motor can be arranged on housing by bonding or that screw is fixing mode; Certainly, the housing of blackboard is also provided with charging inlet, is convenient to charge a battery; This structure, by arranging the fan with dust suction in blackboard eraser housing, the opening switch when blackboard wiping, makes fan produce suction, produces attraction, by chalk dust inspiration blackboard eraser housing by aperture to the chalk dust of blackboard rubbing head; Thus avoid flying upward of chalk dust, alleviate misery and the harm of wiper.
In the present embodiment, described housing sidewall is provided with switch 4, described switch one end connects battery 3, and one end connects motor 8, and by electric wire, motor is connected with battery again, forms loop.This structure, by arranging switch, is convenient to the switch controlling blackboard eraser, avoiding allowing when not using electric motor fan work, avoiding the shortcoming of waste electricity.
In the present embodiment, described housing sidewall is provided with square aperture (not drawing in figure), as shown in Figure 3, described blackboard rubbing head base plate is provided with the plug 7 corresponding with square aperture, and described plug tip is provided with little barb 71.This structure is convenient to dismounting housing and blackboard rubbing head, is also convenient to the chalk dust in inspiration groove to pour out simultaneously.
In the present embodiment, be outside equipped with a dust-absorbing box 10 at described motor and battery; Described dust-absorbing box is fixed by screws on housing; Arrange dust-absorbing box mainly motor and battery and chalk dust to be kept apart; Fan, by chalk dust inspiration dust-absorbing box, avoids chalk dust and adheres on battery and motor, avoids the damage of chalk dust to battery and motor simultaneously.
