Abstract
An electrostatic dust absorption board wiper comprises a handheld face and a hair wiping face. Grooves are arranged in the hair wiping face, an electrostatic generator is arranged in the grooves, and the grooves are arranged among wiping hairs and are three in number. According to the electrostatic dust absorption board wiper, dust generated when a blackboard is wiped is adsorbed on the board wiper by static, damage to teachers and students caused by the dust is avoided, and the environment is prevented from being polluted.
Description
Technical field
The utility model relates to a kind of electrostatic precipitation blackboard eraser.
Background technology
Blackboard eraser is used for erasing the board, and when erasing the board with traditional blackboard eraser, can cause dust from flying, the dust that flies upward is drawn in the body by the academics and students, can produce harm to lung, damage academics and students's health, and the dust that flies upward is come to everywhere and is, causes certain environmental pollution.
The utility model content
When the utility model erased the board with traditional blackboard eraser for solving in the prior art, the dust harzard academics and students health of flying upward also caused this difficult problem of certain environmental pollution, and a kind of blackboard eraser that can effectively prevent dust from flying is provided.
Technical solution adopted in the utility model is:
A kind of electrostatic precipitation blackboard eraser comprises hand-held face and snag face, on the described snag face groove is set, and the generation of static electricity device is set in the groove.
Described groove is arranged in the middle of the snag, and groove is provided with three roads altogether.
The beneficial effect of the relative prior art of the utility model:
The utility model electrostatic precipitation blackboard eraser, the dust that produces when erasing the board, is avoided dust from flying that Faculty and Students are worked the mischief, and is avoided contaminated environment on blackboard eraser by Electrostatic Absorption.
Description of drawings
Fig. 1 is the utility model electrostatic precipitation blackboard eraser structural representation.
Critical piece symbol description in the accompanying drawing:
Among the figure:
1, hand-held face 2, snag face 3, groove 4, generation of static electricity device
The specific embodiment
Followingly the utility model is described in detail with reference to drawings and Examples:
1 one kinds of electrostatic precipitation blackboard erasers of accompanying drawing comprise hand-held face 1 and snag face 2, on the described snag face 2 groove 3 are set, and generation of static electricity device 4 is set in the groove 3; Described groove 3 is arranged in the middle of the snag, and groove 3 is provided with three roads altogether.
The utility model electrostatic precipitation blackboard eraser, the dust that produces when erasing the board, is avoided dust from flying that Faculty and Students are worked the mischief, and is avoided contaminated environment on blackboard eraser by Electrostatic Absorption.
