Abstract

The utility model discloses an electronic blackboard which comprises a blackboard and a writing pen, wherein the blackboard comprises a writing board and a character eliminating button, and the writing board and the character eliminating button are connected by using a conducting wire. The writing pen comprises a pen body and a pen cap, and a sensor is arranged in the writing pen. According to the electronic blackboard, a circuit is arranged in the blackboard, the circuit interacts with the sensor to produce clear handwriting on the writing board, so that the writing pen can really simulate the situation that a chalk is used for writing on an old-fashioned blackboard. In this way, the characters written on the electronic blackboard are almost the same with the characters written on the old-fashioned blackboard.

Description

Electronic blackboard

Technical field

The utility model belongs to technical field of living goods, particularly a kind of electronic blackboard.

Background technology

People often need erase the board in teaching, but when erasing the board, the chalk dust regular meeting of falling down from blackboard aloft disorderly flies, and adheres on people's the hair and clothes, even get in people's the body from nasal cavity and oral cavity.People's the clothes of having made dirty has so on the one hand also endangered the healthy of people on the other hand, some people even because the work of being engaged in teaching for a long time to suck chalk dust too many and suffered from serious tuberculosis.Therefore, making a kind of educational aid new, that be not detrimental to health and replace traditional old-fashioned educational aid, is unusual exigence.

The utility model content

The utility model provides a kind of electronic blackboard simple in structure, easy to use.

A kind of electronic blackboard comprises blackboard and writing pen, and said blackboard comprises the board and the word button that disappears, said board and disappear and have lead to link to each other between the word button.

Said writing pen comprises a body and the cap for brush, in the said writing pen sensor is set.

Because the utility model electronic blackboard is at blackboard set inside circuit, the sensor in ability and the writing pen interacts and on board, produces writing clearly, the situation that writing pen ability real simulated is write on old-fashioned blackboard with chalk.Like this, people are writing to follow on traditional old-fashioned blackboard to write to have what difference hardly on the electronic blackboard.When the word of on people want board, writing is wiped, only need gently one by the word button that disappears, the word on the board just can all disappear, and some vestiges do not stay yet, and people just can continue indiscriminately ad. as one wishes to have write in the above again.Use the utility model electronic blackboard to impart knowledge to students, people's clothes or ill of again not worrying making dirty because of chalk dust.The utility model is simple in structure, easy to use, helps the healthy of people, is a outstanding improvement regeneration product.

Description of drawings:

Below in conjunction with accompanying drawing the utility model electronic blackboard is done explanation further:

Fig. 1 is the structural representation of the utility model electronic blackboard.

Embodiment:
