The working principle and the process of the invention are as follows: before use, the power is turned on or the battery is sufficiently charged, and then sufficient fresh water is stored in the water storage chamber 26, thereby completing the preparation. Then if only normally write the exercise, both can adopt the nib 25 to dip in the clear water and write and also can adopt the water in the water storage cavity 26 to write, become transparent after the coating that discolours on the surface of the cloth 6 that permeates water contacts water in the writing process, because the magnetic switch in the unit 14 that absorbs water does not open at this moment, consequently can not absorb water, the transparent membrane 9 that discolours is transparent, consequently the part of meeting water on the exercise board 1 can directly see the colour on baffle 10 surface from the surface, for example blue, what see when accomplishing the calligraphy exercise at this moment is blue calligraphy typeface. After writing, the water on the permeable cloth 6 can be naturally dried, the electric heating layer can be started to evaporate the water to dryness in advance through electric heating, and the surface of the practice board 1 recovers the white original appearance.

Under the visual mode of brush stroke dwell time, the brush stroke dwell time is different, from shorter time to longer time, and the condition of contact many times, can all see through the solution colour of the different shade that the unit 14 that absorbs water in this scheme shows, can let the person of professor's calligraphy demonstrate under this mode on the one hand, let the student know the dwell time difference of turn change everywhere, and also can let the student practice in this mode, let the teacher know the condition that the student controlled to the brush stroke through the shade change of colour on the characters after writing the completion.

Before entering the mode, the infrared sensor array 2 is turned on to detect whether the pen head 25 contacts the practice board 1, and water is input into the lower chamber through the water pipe 20 to dissolve the water-soluble pigment 12 to form a colored solution until the colored solution contacts the color-changing transparent film at the bottom to turn the colored solution into white (which can be observed through a single-point dripping test, or observed by arranging a transparent plate on the side wall of the practice board). In order to ensure that the water content of the pen point 25 is stable in the mode, the pressure sensor 23 senses whether water needs to be discharged or not, and the constant flow valve 28 is opened to stably supply water, so that the phenomenon that the water content of the pen point 25 is changed too much in the writing process is avoided. When the pen head 25 contacts the practice board 1, the infrared sensor array 2 sends a signal, and the control module opens the electromagnet layer 21 to generate magnetic force. The magnet 16 of the magnetic switch moves downwards under the influence of magnetic force, so that the side edge of the elastic reed 13 bends downwards, the middle part of the side edge of the reed arches upwards, and the water inlet hole 17 is opened.

After writing is started, the fine conduit 7 of the water absorbing unit 14 contacted by the pen point 25 absorbs water at the top into the lower chamber 11, the water-soluble pigment 12 is dissolved to form a colored solution, and the colored solution immediately overflows the color-changing transparent film 9 at the lowest layer through the water through pores 15 after water is absorbed through the fine conduit 7. In the lowest film layer cavity 8, the pigment concentration is higher, so the color is darker, and at the same time, the color-changing transparent film 9 in the lowest layer changes to white when meeting water to shield the color of the partition board 10, so that the color of the colored solution in the lowest film layer cavity 8, such as red, can be seen from the surface of the exercise board 1 when meeting water, and then red calligraphy characters can be seen when the calligraphy exercise is completed.

When the contact time increases or the contact frequency increases, the water absorbed by the water absorption unit 14 is increased, so that the color concentration is reduced while the liquid level of the colored solution is increased. Therefore, the multilayer film layer cavity 8 is formed by reasonable layering, and the colored solutions with different concentrations can be obviously distinguished. When the colored solution enters the film layer cavities 8 with different heights, the color of the solution at the lower layer is changed into white by the color-changing transparent film 9 at the bottom of the colored solution, so that the color shade change of the solution in each film layer cavity 8 is more obvious from the upper part.

When the pen point 25 is not in contact with the practice board 1, the electromagnet layer 21 is immediately closed to lose magnetic force, so that the magnetic switches in the water absorption units 14 are automatically closed, the colored solution cannot discharge water, the liquid level height remains unchanged, and the corresponding color can be kept unchanged.

When the water absorption type water absorption device is repeatedly used, the electromagnet layer 21 can be opened, the heating layer 18 is opened for heating, so that water can be evaporated under the condition that the magnetic switch opens the water through pores 15, the water-soluble pigment 12 can be separated out again at the bottom of the lower chamber 11 along with the water evaporation, water can be absorbed when the magnetic switch is opened again by the water absorption unit 14 next time, and the color of the displayed characters has shade change.

The invention is described above with reference to the accompanying drawings, it is obvious that the specific implementation of the invention is not limited by the above-mentioned manner, and it is within the scope of the invention to adopt various insubstantial modifications of the inventive concept and solution of the invention, or to apply the inventive concept and solution directly to other applications without modification.
