Description

An easy-to-clean dustproof blackboard eraser

technical field

The utility model relates to a blackboard eraser, in particular to an easy-to-clean dustproof blackboard eraser.

Background technique

Chalk and blackboard are one of the most primitive and traditional main teaching methods, but with the accelerated pace of social work and life, the rate of occupational diseases of teachers is on the rise year by year, and the occupational diseases of teachers are developing in a variety of directions, among which occupational diseases caused by chalk dust The harm caused by it is almost comparable to that caused by smoking, and the health problems caused by dust are affecting the physical and mental health of contemporary teachers. On the one hand, the current blackboard erasers are simple in structure, difficult to effectively contain dust, and difficult to clean; on the other hand, although some dust-absorbing blackboard erasers appear, they are often complicated in structure and ineffective.

Utility model content

The purpose of the utility model is to solve the shortcomings in the prior art, and propose an easy-to-clean dust-proof blackboard eraser.

In order to achieve the above object, the utility model adopts the following technical solutions:

An easy-to-clean dust-proof blackboard eraser, comprising a front part of a blackboard eraser, a brush (5), a dust suction fan (8) and a blackboard eraser rear cover, characterized in that it also includes a dust suction board (10), fixed on both sides There are wet sponges (6) and springs (3); the chamber behind the blackboard eraser has grooves and water outlet holes (7) on the side wall at the position of the dust collection plate (10); the filter plate (4) is a row of single To the fan blade, filter cotton (9) is attached on the fan blade; the limit block (2) is arranged above the dust suction plate (10).

Preferably, a handle (1) is connected to the rear cover of the blackboard eraser.

Preferably, the rear chamber is provided with detachable side panels.

Preferably, there are four springs (3).

Preferably, the fan and the dust collection board (10) are connected through guide rods.

Preferably, the size of the rear chamber of the blackboard eraser is larger than that of the front part of the blackboard eraser.

Preferably, the dust collection board (10) is provided with drainage grooves (11).

Compared with the prior art, the utility model generates suction through the fan, sucks the chalk dust through the filter plate (4) on the wet sponge attached to the dust-absorbing plate (10), the dust-absorbing plate (10) can be disassembled, and Squeeze the wet sponge of the dust-absorbing board (10) through the back cover, and the chalk dust is automatically removed, that is, the utility model effectively solves the problem of chalk dust flying around, and can clean the blackboard eraser better, which is helpful for teaching work more Carry out well to protect the health of teachers and students.

Description of drawings

Fig. 1 is a structural schematic diagram of the control panel proposed by the utility model.

detailed description

The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. example.

When the utility model is in use, the dust suction fan (8) of the blackboard eraser sucks the chalk dust into the rear chamber of the blackboard eraser through the filter plate (4). The filter plate (4) is set in one direction and is attached with filter cotton (9). , can make the chalk ash enter in one direction, and prevent the chalk ash entering from overflowing again.

After using the blackboard eraser for many times, the side panel of the rear chamber is removed, and then the dust collection board (10) is slid out through the groove, so that the dust collection board (10) can be easily taken out.

After taking out the dust collection board (10), reverse the front and back of the dust collection board (10), and then slide it into the rear chamber along the groove. After installing the side board, inject water into the wet sponge through the water injection hole, and then squeeze Press the back cover, and the sewage will be discharged along the drainage groove (11) through the water outlet hole (7), which can easily clean the absorbent sponge and achieve the effect of repeated use. Because one side of the wet sponge on both sides is always clean, it is not necessary to take it out completely for soaking and cleaning, which can save time, and through the parallel extrusion of the rear cover and the vacuum board (10), the chalk dust can be effectively cleaned, and it can prevent wet Sponge deformed or falling off. Moreover, the blackboard eraser is provided with a handle (1), which can save labor and be more convenient.

The above is only a preferred embodiment of the utility model, but the scope of protection of the utility model is not limited thereto. The equivalent replacement or change of the new technical solution and the concept of the utility model shall be covered by the protection scope of the utility model.
