Abstract

The invention provides a dust suction blackboard eraser. The dust suction blackboard eraser comprises an erasing strip and a fixed plate, wherein the erasing strip is fixed on a plate surface on one side of the fixed plate; the fixed plate is further fixedly provided with an electrostatic guide plate and an electrostatic generator; the electrostatic generator is electrically connected with the electrostatic guide plate. The problems that a blackboard and chalks are commonly used for teaching in schools, and a lot of chalk dust is generated in a use process and diseases including pneumoconiosis and the like are easy to cause after the dust is inhaled by a human body, so that the damages to the human body is very great, the pneumoconiosis nearly becomes an occupational disease of teachers and the dust also has larger damages to students are solved. The dust suction blackboard eraser belongs to the field of teaching tools.

Description

A kind of dust absorption blackboard eraser

Technical field

The present invention relates to a kind of blackboard eraser, be specifically related to a kind of blackboard eraser being absorbed chalk dust by electrostatic.

Background technology

At present, all generally that the form adopting blackboard to add chalk is imparted knowledge to students in school, in use can produce a large amount of chalk dusts, suck after in human body and be easy to cause the diseases such as pneumoconiosis, very large to harm, the occupational disease of the current almost Cheng Liao teacher of pneumoconiosis, also has larger harm to student.

Summary of the invention

The object of the invention is to: a kind of dust absorption blackboard eraser is provided, all generally that the form adopting blackboard to add chalk is imparted knowledge to students to solve in school, in use can produce a large amount of chalk dusts, suck after in human body and be easy to cause the diseases such as pneumoconiosis, very large to harm, the occupational disease of the current almost Cheng Liao teacher of pneumoconiosis, also has the problem of larger harm to student.

The solution of the present invention is as follows: a kind of dust absorption blackboard eraser, comprises wiper rail and fixed head, and wiper rail is fixed on the plate face of fixed head side, and described fixed head is also fixedly installed electrostatic guide plate and electrostatic generator, and electrostatic generator and electrostatic guide plate are electrically connected.

Described fixed head is bar shaped plank.

Described electrostatic generator is arranged on the inside of fixed head.

The one side that described fixed head is relative with wiper rail is also provided with fingerstall, and the two ends of fingerstall are all fixed on fixed head.

Described electrostatic guide plate is arranged between fixed head and wiper rail.

The control button of electrostatic generator is arranged on the inner side of fingerstall, and when gloves are on fingerstall, hand can be automatically that electrostatic guide plate passes into electrostatic by the control button being pressed in electrostatic generator starts electrostatic generator.

The present invention compared with prior art; major advantage produces electrostatic by the electrostatic generator on chalkboard eraser and passes on electrostatic guide plate; by the dust that Electrostatic Absorption drops in blackboard wiping process; dust is prevented to be inhaled in human body; reduce the pathogenetic possibilities of dust disease such as pneumoconiosis, the health of protection " engineer of the soul ".

Accompanying drawing explanation

Fig. 1 is structural representation of the present invention.

Detailed description of the invention

For making technical scheme of the present invention more clear, below in conjunction with accompanying drawing, specific embodiments of the invention are described in further detail,

With reference to Fig. 1, the invention provides a kind of dust absorption blackboard eraser, comprising:

Wiper rail 1 and fixed head 2, wiper rail 1 is fixed on the plate face of fixed head 2 side, described fixed head 2 is also fixedly installed electrostatic guide plate 3 and electrostatic generator 4, and electrostatic generator 4 and electrostatic guide plate 3 are electrically connected.

Described fixed head 2 is bar shaped plank.

Described electrostatic generator 4 is arranged on the inside of fixed head 2.

The one side that described fixed head 2 is relative with wiper rail 1 is also provided with fingerstall 5, and the two ends of fingerstall 5 are all fixed on fixed head 2.

Described electrostatic guide plate 3 is arranged between fixed head 2 and wiper rail 1.

The control button of electrostatic generator 4 is arranged on the inner side of fingerstall 5, and when gloves are on fingerstall 5, hand automatically can pass into electrostatic by the control button being pressed in electrostatic generator 4 starts electrostatic generator 4 for electrostatic guide plate 3.
