Abstract
The invention discloses an electric blackboard eraser, belonging to the field of teaching supplies. The electric blackboard eraser comprises a dust box, a dust collection device, a box cover, a battery box, dust collection channels and a sponge eraser, and further comprises a solar energy panel and a pressure sensor, wherein the solar energy panel is installed above the box cover; the dust collection channels are positioned on both sides of the sponge eraser; and the pressure sensor is mounted in the sponge eraser; and the dust collection device is provided with two power supply modes of battery power supply and solar power supply. The electric blackboard eraser has the following beneficial effects that the blackboard eraser is about to automatically turn on the dust collection device when the blackboard is erased so that the chalk dust is absorbed effectively, the power supply modes are diverse, and the convenience in use is achieved.
Description
Technical field
The present invention relates to a kind of electric blackboard eraser, belong to the realia field.
Background technology
Blackboard, blackboard eraser and chalk are the requisite realias of school instruction, can produce a large amount of chalk dusts when erasing the board, because this chalk dust is lighter, be difficult for sinking, so chalk dust can wave in the classroom for a long time, Faculty and Students suck for a long time chalk dust and can damage health.
Summary of the invention
Problem for above-mentioned prior art exists the invention provides a kind of electric blackboard eraser, and blackboard eraser can be opened dust exhaust apparatus automatically when erasing the board, and effectively siphons away chalk dust, and power supply mode is various, and is easy to use.
To achieve these goals, the technical solution used in the present invention is: a kind of electric blackboard eraser, comprise dust box, dust exhaust apparatus, lid, battery case, dust absorption passage and sponge brush, also comprise solar panels and pressure sensor, solar panels are contained in the lid top, dust absorption passage is positioned at the sponge brush both sides, and pressure sensor is contained in the sponge brush the inside, and dust exhaust apparatus has powered battery and solar powered two kinds of power supply modes.
The invention has the beneficial effects as follows: blackboard eraser can be opened dust exhaust apparatus automatically when erasing the board, and effectively siphons away chalk dust, and power supply mode is various, and is easy to use.
Description of drawings
Fig. 1 is structural representation of the present invention
Among the figure: 1, dust box, 2, dust exhaust apparatus, 3, lid, 4, solar panels, 5, battery case, 6, dust absorption passage, 7, sponge brush, 8, pressure sensor.
The specific embodiment
The invention will be further described below in conjunction with accompanying drawing.
As shown in Figure 1, the present invention includes dust box 1, dust exhaust apparatus 2, lid 3, battery case 5, dust absorption passage 6 and sponge brush 7, also comprise solar panels 4 and pressure sensor 8, solar panels 4 are contained in lid 3 tops, dust absorption passage 6 is positioned at sponge brush 7 both sides, pressure sensor 8 is contained in sponge brush 7 the insides, and dust exhaust apparatus 2 has powered battery and solar powered two kinds of power supply modes.
All be firmly to be attached to blackboard eraser on the blackboard when erasing the board, about back and forth wiping, pressure sensor 8 of the present invention is contained in sponge brush 7 the insides, when sponge brush 7 is attached on the blackboard, and pressure sensor 8 pressurizeds, dust exhaust apparatus 2 starts automatically, dust absorption passage 6 is positioned at sponge brush 7 both sides, when about back and forth during wiping, chalk dust will suck the dust boxes 1 from the dust absorption passage 6 of sponge brush 7 both sides, dust exhaust apparatus 2 has powered battery and solar powered two kinds of power supply modes, and it is more convenient that electric blackboard eraser is used.
