Abstract
The utility model discloses a dust collection blackboard eraser which comprises a blackboard eraser box, a hidden plug arranged at one end of the blackboard eraser box, a power switch and a charging indicator, wherein absorbing holes and bristles are arranged on the front side of the blackboard eraser box, a solar panel is arranged on the back side of the blackboard eraser box, the power switch is connected with the absorbing holes through the solar panel, the charging indicator is connected with the power switch, and the hidden plug is connected with the absorbing holes through the power switch, solar energy is converted into electrical energy, the bristle can be used for erasing chalk dust, and the absorbing holes inside the blackboard eraser box can absorb the chalk dust away, so as to prevent the chalk dust from spreading and reduce harms caused by the chalk dust to human body, and energy conservation and environment friendliness are achieved.
Description
Technical field
The utility model relates to a kind of dust absorption blackboard eraser.
Background technology
Dust was too big when existing blackboard eraser used, and polluted classroom environment, unfavorable health.
Summary of the invention
The purpose of this utility model provides a kind of dust absorption blackboard eraser.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of dust absorption blackboard eraser, comprise the wiping box, wipe box one end and be provided with hiding plug, power switch and charging indicator light, wipe the box front and be provided with suction hole and bristle, wipe the box back side and adopt solar panel, power switch is connected with the suction hole by solar panel, and charging indicator light is connected with power switch, hides plug and is connected with the suction hole by power switch.
Owing to adopt said structure, become electric energy by conversion of solar energy, by bristle chalk dust to be wiped, the suction hole of wiping in the box just siphons away chalk dust, and dust can not filled the air everywhere, reduces the injury of chalk dust to human body, energy-conserving and environment-protective.
Description of drawings
Be described further below in conjunction with the drawings and specific embodiments.
Fig. 1 is a structural representation of the present utility model.
The double accompanying drawing that makes an abstract of Fig. 1.
The specific embodiment
As shown in the figure, a kind of dust absorption blackboard eraser, comprise and wipe box 1, wipe box 1 one ends and be provided with hiding plug 2, power switch 3 and charging indicator light 4, wipe box 1 front and be provided with suction hole 5 and bristle 6, wipe box 1 back side and adopt solar panel, power switch 3 is connected with suction hole 5 by solar panel, charging indicator light 4 is connected with power switch 3, hides plug 2 and is connected with suction hole 5 by power switch 3.
Solar panel is full of electricity, and indicator lamp to be charged is bright after green, turns on the power switch 3, inhales hole 5 and can siphon away chalk dust automatically.If the solar energy deficiency can skid off hiding plug 2, charge.After dust is filled, the lid of wiping box 1 back side is opened, chalk dust is outwelled.
