In order to explain the technical solution of the present invention, the following description is made by way of specific examples, and only the portions related to the embodiments of the present invention are shown.

As shown in fig. 1-2, the present invention provides an embodiment of a writing system for an electric capacity whiteboard, comprising an electric capacity whiteboard writing pen 1, an electric capacity whiteboard writing device 2, and an electric capacity whiteboard eraser 3. The capacitive whiteboard writing pen 1 is used for writing on the capacitive whiteboard writing device 2 and can write ink marks of various colors; the capacitive whiteboard writing device 2 is used for presenting ink marks of various colors written by the capacitive whiteboard writing pen 1 in real time and identifying, processing, displaying and/or storing digital coordinate handwriting corresponding to the ink marks; and the intelligent blackboard eraser 3 is used for erasing ink marks of various colors on the capacitive whiteboard writing device 2 when the capacitive whiteboard writing device 2 is abutted and moved, and enabling the capacitive whiteboard device to recognize the digital coordinate handwriting and further erase the digital coordinate handwriting simultaneously.

In this embodiment, the capacitive whiteboard writing system further comprises a display device 5 and a control device 4; the control device 4 is in communication connection with the capacitive whiteboard writing device 2 and the display device 5; the communication connection may be a wired communication connection and/or a wireless communication connection. The display device 5 is fixedly connected with the capacitive whiteboard writing device 2, or the display device 5 and the capacitive whiteboard writing device 2 are arranged separately; and the display device 5 is used for displaying the recognized digital coordinate handwriting. Note that the display device 5 may be a capacitive touch display screen.

As is well known, when a human body is an electric conductor with electric charge, a person holds a conductive capacitive whiteboard writing pen 1 to write on a capacitive whiteboard writing device 2, so that digital coordinate handwriting is presented, the digital coordinate handwriting can be displayed on the capacitive whiteboard writing device 2 in real time, and if the capacitive whiteboard writing pen 1 is filled with writing liquid (such as ink, and a conductive additive is added in the ink), the writing liquid presents ink marks (marks left on the surface of the capacitive whiteboard writing device by a writing pen core). In addition, the capacitive whiteboard writing arrangement 2 is capable of recognizing and processing digital coordinate writing and is also capable of being stored by a control device (see below) or displayed on a display device (see below) by the control device. Further, the existing common eraser for ink marks can be erased, but the digital coordinate handwriting cannot be erased at the same time, so that the intelligent eraser 3 of the embodiment is conductive, and the purpose of erasing the digital coordinate handwriting by using the intelligent eraser 3 is realized through the capacitive whiteboard writing device 2 (see the following description). Therefore, the system can write and display ink marks in real time or only write and display digital coordinate handwriting in real time (ink is not added to a capacitive whiteboard writing pen), and can store and/or display the recognized and processed digital coordinate handwriting on a display device, and when the digital coordinate handwriting and/or the ink marks need to be erased, the written digital coordinate handwriting and/or the ink marks are erased through the intelligent blackboard eraser 3. Of course, the ink can be presented with different colors by ink with different colors, and the digital coordinate handwriting can also be set with different colors by a software system.

As shown in fig. 3, the capacitive whiteboard marker 1 comprises a conductive pen shell 10, a writing pen core 11 and a conductive writing liquid. Specifically, the writing core 11 is embedded in one end of the conductive pen shell 10, the writing liquid is stored (injected) in a space formed by the conductive pen shell 10 and the writing core 11, and the conductive pen shell 10 and the writing core 11 are electrically contacted through the writing liquid and form a conductive whole. The length of the writing pen core 11 is smaller than that of the conductive pen shell 10, and the whole conductive pen shell 10 is not necessarily filled with the writing liquid, so that the cost of the capacitive whiteboard writing pen 1 is reduced conveniently. Meanwhile, the writing liquid may be stored in the conductive pen case 10 by other storage forms, which are not particularly limited herein. Further, since the conductive pen case 10, the writing liquid and the writing pen core 11 are a conductive whole, the writing liquid penetrates into the writing pen core 11, and the conductive pen case 10 is held by a hand of a person to contact the writing pen core 11 with the capacitive whiteboard writing device 2, so that the capacitive whiteboard writing device 2 can write. In addition, the writing pen core 11 of the hand-operated conductive pen casing 10 can be in contact with the capacitive whiteboard writing device 2 (or other display device, display device 5) to operate the capacitive whiteboard writing device 2 (or other display device, display device 5), so as to achieve the purpose of simultaneously writing and operating the capacitive whiteboard writing device 2 (or other display device, display device 5). It should be noted that the conductive pen case 10 can be an existing common whiteboard pen case, which is electrically processed, for example, replaced with a conductive metal case, sprayed or plated with a conductive material, and the like, so as to have conductivity. The writing core may be made of conductive material or non-conductive material, and the writing core is not limited herein. Therefore, the capacitive whiteboard writing pen 1 of the embodiment adds a conductive function on the basis of the whiteboard pen, so as to achieve the functions of the whiteboard pen and the capacitive pen.

Further, the writing core 11 may be embedded in one end of the conductive pen shell 10 in a tight fit or a plug-in manner. When the conductive pen shell 10 and the writing pen core 11 are tightly matched, the conductive pen shell 10 and the writing pen core 11 are not detachable, so that the capacitive whiteboard writing pen 1 is disposable, and when the conductive pen shell 10 and the writing pen core 11 are inserted, the conductive pen shell 10 or the writing pen core 11 of the capacitive whiteboard writing pen 1 can be replaced. In order to increase the conductivity of the writing pen 1 for the capacitive whiteboard, the following measures are taken: the inner surface of the conductive pen shell 10, the part of the conductive pen shell 10, which is in contact with the writing pen core 11, and the outer surface of the conductive pen shell 10 are all covered with conductive materials (such as sprayed conductive oil); the outer surface of the conductive pen shell 10 is provided with a conductive printing silk or label; furthermore, a conductive aid is added to the writing liquid. The conductive performance of the capacitive whiteboard writing pen 1 can be effectively enhanced in the above mode, and then better writing effect, digital coordinate handwriting recognition effect and touch screen control effect are achieved. In addition, other can write the pen conduction to electric capacity whiteboard writing device with human electric charge through electric capacity whiteboard all be in the utility model discloses in the protection range, do not limit one by one here.

In this embodiment, the conductive pen shell 10 is made of conductive metal or alloy, or conductive plastic, and the existing conductive metal, alloy, or plastic can be used as the conductive pen shell 10 of this embodiment; alternatively, the conductive pen housing 10 is a non-conductive material. When the conductive pen shell 10 is made of a non-conductive material, the whole pen shell needs to have a conductive property, and therefore, conductive materials need to be covered on the inner surface of the conductive pen shell 10, a portion of the conductive pen shell 10, which is in contact with the writing pen core 11, and the outer surface of the conductive pen shell 10 (the covering mode may be a plating or spraying mode), and the inner surface and the outer surface of the conductive pen shell 10 are electrically connected to form a conductive whole, so that the conductive effect of the whole conductive pen shell is achieved. Of course, any material suitable for electroplating in the prior art can be used as the conductive material of the present embodiment.
