Abstract
The utility model relates to a dust-sucking blackboard eraser adopting static material to absorb dust. The dust-sucking blackboard eraser comprises a blackboard eraser; and the erasure surface of the blackboard eraser adopts an electrostatic adsorption felt board. The dust-sucking blackboard eraser has the advantages that firstly, the inconvenience and difficult maintenance of installing a dust exhaust apparatus on a blackboard is solved; secondly, compared with the prior dust-sucking blackboard eraser, the dust-sucking blackboard eraser has the advantages of simple process, low cost and convenient cleaning and maintenance.
Description
Technical field
The utility model relates to a kind of dust absorption blackboard eraser with electrostatic material absorption dust, belongs to blackboard eraser and makes the field.
Background technology
The dust exhaust apparatus majority that adopts in the school is mounted on the blackboard at present, and is cumbersome, and maintenance is inconvenience also, and the blackboard eraser on the market scarcely has dust-absorbing function, serious to academics and students's health hazard.Though also there are some blackboard erasers with dust-absorbing function to occur, often because complex structure, manufacturing cost is high and can't popularize on a large scale.
Summary of the invention
Purpose of design: avoid the weak point in the background technology, design a kind of simple in structure, manufacturing is convenient, cost is low, clean electrostatic precipitation blackboard eraser easy to maintenance.
Design: to achieve these goals.1, the material with cleaning part in the traditional blackboard wiping changes the Electrostatic Absorption felt plate with dust-absorbing function into, is one of characteristics of the present utility model.The purpose of doing like this is: Electrostatic Absorption felt plate has good dust-absorbing function, and it can be by the static that is produced in the wiping process, with dust absorption, avoids chalk dust to fly upward the harm that causes to environment and health.
Technical scheme: a kind of dust absorption blackboard eraser, it comprises blackboard eraser, described blackboard eraser wiping surface is an Electrostatic Absorption felt plate.
The utility model is compared with background technology, and the one, solved dust exhaust apparatus has been installed in the inconvenience on the blackboard and the situation of maintenance difficult; The 2nd, for existing dust absorption blackboard eraser, have the characteristics that structural manufacturing process is simple, cost is low, cleaning is easy to maintenance.
Description of drawings
Fig. 1 is the schematic diagram of electrostatic precipitation blackboard eraser.
The specific embodiment
Embodiment 1: with reference to accompanying drawing 1.A kind of dust absorption blackboard eraser, it comprises blackboard eraser 1, described blackboard eraser 1 wiping surface is an Electrostatic Absorption felt plate 2.
Have the hole on 2 of the described Electrostatic Absorption felt plates, the back side is equipped with the Electrostatic Absorption film.
What need understand is: though the foregoing description is to the utility model detailed text description of contrasting; but these text descriptions; just the simple text of the utility model mentality of designing is described; rather than to the restriction of utility model mentality of designing; any combination, increase or modification that does not exceed the utility model mentality of designing all falls in the protection domain of the present utility model.
Claims (2)
1. electrostatic precipitation blackboard eraser, it comprises blackboard eraser, it is characterized in that: it is Electrostatic Absorption felt plate that described blackboard eraser is wiped examination face.
2. electrostatic precipitation blackboard eraser according to claim 1 is characterized in that: have the hole on the described Electrostatic Absorption felt plate face, the back side is equipped with the Electrostatic Absorption film.
