Abstract
The invention relates to a solar energy dust absorption blackboard eraser. The blackboard eraser mainly comprises a shell and bristle, wherein the shell has a cuboid hollow structure; the bristle is connected to the center of the bottom surface of the shell; air vents are formed around the bristle on the bottom side of the shell; a micro dust collector is arranged in the shell; a solar energy absorption plate is fixed on the top surface of the shell and is connected with a storage battery; and the storage battery is connected in series with a switch and the micro dust collector to form a circuit. The invention has the advantages that: the blackboard eraser has a peculiar function, is easy and convenient to operate, is safe and reliable, is convenient to use, and the like.
Description
Technical field
The present invention relates to a kind of educational aid, especially a kind of blackboard wiping instrument.
Background technology
As everyone knows, blackboard eraser is a blackboard wiping instrument the most basic in the school instruction.At present, blackboard eraser mainly is made up of shell and bristle two parts, comes the wiping chalk writing through bristle, accomplishes clean up task.But, in wiping process, have a large amount of chalk dusts and produce, have a strong impact on the healthy of teachers and students, and present blackboard eraser does not generally possess dust-absorbing function.
Summary of the invention
The purpose of this invention is to provide a kind of solar energy dust absorption blackboard eraser that absorbs chalk dust and save the energy.
The present invention mainly comprises shell and bristle, and shell is the cuboid hollow-core construction, and the bottom center place connects bristle, offers air-vent on the base around bristle; Micro-cleaner is installed by portion in the enclosure; At outer casing top surface fixed solar baffle, solar absorption panels is connected with battery, and battery and switch, micro-cleaner are composed in series circuit.
During use, solar absorption panels can absorb solar energy, and becomes electric energy that battery is charged conversion of solar energy.During blackboard wiping, the user holds shell, utilizes bristle to carry out wiping, simultaneously, close switch, battery is that micro-cleaner provides electric energy, and dust catcher is started working, the chalk dust of brushing bristle sees through in the air-vent suction dust catcher, reduces dust pollution.
Compared with present technology, beneficial effect of the present invention is: function is peculiar, easy and simple to handle, safe and reliable, easy-to-use, can absorb chalk dust, and health, teaching environment easily are provided.
Description of drawingsFig. 1 is a side view of the present invention.
Fig. 2 is a upward view of the present invention.
The specific embodimentIn stereochemical structure sketch of the present invention shown in Figure 1, mainly comprise shell 1 and bristle 2, shell is the cuboid hollow-core construction, the bottom center place connects bristle, offers air-vent 3 on the base around bristle; Micro-cleaner 4 is installed by portion in the enclosure; At outer casing top surface fixed solar baffle 5, solar absorption panels is connected with battery 6, and battery and switch, micro-cleaner are composed in series circuit.
