Abstract
An environment-protecting dust suction blackboard eraser belongs to the teaching appliance, which comprises a blackboard eraser and a minitype dust collector arranged in the blackboard eraser. The blackboard eraser comprises a dust suction plate and a brushing surface fixed on the dust suction plate, and the dust suction plate is provided with a dust suction hole which let the dust pass through. The minitype dust collector is arranged in the cavity constituted by a house body, an upper cover, clapboard and an airproofed plate, and the clapboard, the dust suction plate, the lower cover, the airproofed plate and the house body surrounds a dust suction storehouse. A filtration storehouse which can collect the dust is arranged at the front end of the dust suction mouth of the minitype dust collector, with the mouth facing to the dust suction storehouse. The utility model skillfully blends the dust collector and the blackboard eraser as one body, and is convenient to take with a good dust suction effect, which stops the dust pollution and is helpful for the health of the teacher and the student.
Description
Technical field
The utility model belongs to teaching aid, a kind of specifically blackboard eraser.
Existing blackboard eraser causes chalk dust to fly upward when using easily, has a strong impact on teachers and students' health, and bristle wearing and tearing simultaneously are very fast, and the disposable use of brush board is wasted very big.Though someone has invented and has a kind ofly alleviated the dust absorption blackboard eraser of dust by Electrostatic Absorption, does not tackle the problem at its root.
Summary of the invention
A kind of environment-friendly type dust absorption blackboard eraser, comprise blackboard eraser and the micro-cleaner (8) that is positioned at wherein, blackboard eraser is made of dust-catching board (3) and the wiping face (1) that is fixed thereon, also be shaped on the air suction opening that dust is passed through on the dust-catching board, micro-cleaner (8) is positioned at the chamber that housing (13), loam cake (11), dividing plate (14) and sealing plate (11) constitute, and dividing plate (14), dust-catching board (13), lower cover (5), sealing plate (7) and housing (13) surround dust suction storehouse (4).Be equipped with the filtering cabin (5) of collecting dust at micro-cleaner (8) suction port front end, its opening is facing to dust suction storehouse (4).
Filtering cabin (5) one ends are connected on the lower cover (6), and the other end is matched with sealing plate (7) one sides.The cleaning dust is very convenient like this.
Wiping face (1) is fixed on the dust-catching board (3) with bonding die (2), and wiping face (1) is positioned at dust-catching board (3) central authorities, and air suction opening is positioned on the dust-catching board and around the wiping face of being distributed in.It is removable that wiping face (1) is bonded on the bonding die (2).This structure makes the air suction opening of dust around the wiping face and is inhaled in the dust suction storehouse, and it is simpler to wipe the face fixed form simultaneously, is convenient to change.
For ease of carrying, the utility model preferentially recommends micro-cleaner to use battery (9) that power is provided, and it is positioned at micro-cleaner (8) rear portion, and the rechargeable battery two ends link to each other with charging socket (10) with switch (12) by lead.
The utility model adopts unique design that dust catcher and blackboard eraser are combined together cleverly, and volume is little, and is in light weight, and the replaceable wiping face made of high-abrasive material has prolonged service life greatly in addition, and the micro-cleaner pick-up performance is good, has stopped dust pollution substantially.
