The reversible color-changing material is an viologen derivative material.

And each adjacent plate seat is in contact alignment up and down.

Contrast prior art, the beneficial effects of the utility model reside in that:

the device uses the electrochromic device made of the viologen derivative material to make the four-wire three-grid line, and the four-wire three-grid line can be displayed through switch control, so that the device is convenient for English teaching. When the whiteboard is used for teaching other subjects, the electrochromic device is not electrified, and four-wire three-grid lines cannot be displayed.

Detailed Description

The present invention will be further described with reference to the following specific examples. It should be understood that these examples are for illustrative purposes only and are not intended to limit the scope of the present invention. Furthermore, it should be understood that various changes or modifications of the present invention may be made by those skilled in the art after reading the teachings of the present invention, and these equivalents also fall within the scope defined in the present application.

The utility model relates to a teaching whiteboard convenient for English learning based on electrochromic principle, the main structure of which comprises a whiteboard body 1, a rear board sleeve 2 and an electrochromic device; the face of the whiteboard body 1 is a glass face, the four vertex angles of the whiteboard body 1 are provided with clamping sleeves 9, and the whiteboard body 1 is clamped on the rear board sleeve 2 through the clamping sleeves 9.

The main technical point is that the electrochromic device, and the following details are provided for the electrochromic device:

electrochromic device is including setting up box body 3 and electrochromic device 4 in whiteboard body 1 both sides, and the inside circuit board that sets up of box body 3, the inboard of box body 3 are equipped with a plurality of connection socket 5, and the outside of box body 3 is equipped with a plurality of switch 6. Each wire of the four-wire three-grid wire is made of an electrochromic device 4, the electrochromic device 4 is made of a reversible color-changing material, and preferably made of a cheap material which is widely and practically applied to an ultraviolet derivative material. The viologen derivative belongs to a cathode color-changing material, and when voltage is applied to the material, the viologen derivative can generate reduction reaction to change the oxidation state of the viologen derivative so as to develop color. Wherein the total oxidation state is a stable state, and most of the total oxidation state is yellow. The color displayed by the compound has a certain relation with the type of the connected substituent, and mainly the electronic effect of the substituent plays a role. Blue violet is present when the substituent is an alkyl group. The shade of the color depends on the molar absorption coefficient value of the material, the magnitude of which is related to the structural type of the molecular structure molecule. The viologen has very good redox reversibility, and can maintain the structural stability in the repeated redox process.

Each wire of the four-wire three-grid wire is made of an electrochromic device 4 made of an ultraviolet derivative material, the color of the electrochromic device 4 is white, each wire made of the electrochromic device 4 is embedded on a white board seat 7, the board seats 7 correspond to the connection socket 5, and the connection plug 8 at the tail end of each board seat 7 is in butt joint with the connection socket 5 to achieve circuit communication. And each adjacent plate seat 7 is in contact alignment up and down. After the power switch 6 is pressed down and the power is switched on, the four-wire three-grid line can be displayed after changing color, and the primary color can be recovered after the power is switched off.

It is again explained that the strip-shaped lamp strip is not used because the strip-shaped lamp strip is a luminous lamp strip, so that the wires of the four wires and the three grids are idle to be thick, and a board seat 7 with the same color as the luminous lamp strip needs to be found for placing the lamp strip, the effect is not good, and the lamp strip can be obviously seen when the lamp strip is not electrified. This is a significant disadvantage. Therefore, the electrochromic device 4 made of the viologen derivative material can easily solve the problem. The four-wire three-grid line can be displayed through switch control, so that the English teaching is convenient. When the whiteboard is used for teaching other subjects, the electrochromic device 4 is not electrified, and four-wire three-grid lines cannot be displayed.
