Detailed Description
In order to make the technical problem, technical solution and advantageous effects to be solved by the present invention more clearly understood, the following description is given in conjunction with the accompanying drawings and embodiments to illustrate the present invention in further detail.
It should be noted that the terms "disposed" and "connected" should be interpreted broadly, and may be, for example, fixedly connected, detachably connected, or integrated; can be mechanically or electrically connected; they may be directly connected or indirectly connected through intervening media, or they may be connected internally or in any other suitable relationship, unless expressly stated otherwise. The terms "upper", "lower", "end", and the like indicate orientations or positions based on the orientations or positions shown in the drawings, and are only for convenience of description and not to be construed as limiting the technical solution. The meaning of "a number" is one or more unless specifically located otherwise.
Example one
Referring to fig. 1, the present embodiment provides a conductive chalk for an intelligent blackboard, including a cylindrical conductor 1, the conductor 1 has two opposite ends and an outer surface located between the two ends for a user to hold, the conductor 1 is made of a plurality of conductive fibers 101, the conductive fibers 101 include wool fibers and structural charges uniformly distributed on the wool fibers, and the fiber has a conductive performance by increasing the structural charges inside the fiber during a production process and reducing a resistance coefficient of the fiber. When a user holds the conductive chalk to contact with the conductive writing induction area of the intelligent blackboard, due to the fact that the human body is grounded, the conductive chalk in the hand is in contact with the conductive writing induction area to form an equivalent capacitor, high-frequency signals can flow into the ground wire through the equivalent capacitor, therefore, the electric charge received by the receiving end is reduced, and when the user uses the conductive chalk to contact with the conductive writing induction area, the touched point is determined according to the current intensity received by the receiving end. And the points form a written electronic handwriting in the writing movement, and the electronic handwriting is converted into the written handwriting to be stored.
The utility model discloses an electrically conductive chalk has the appearance of chalk, accords with the chalk use habit that the user has formed, and the promotion is write and is experienced, and whole material is the same, is formed by the preparation of a plurality of conductive fiber 101, wholly possesses the function that the touch-control was write, and consumable length improves greatly, writes life-span and compares ordinary chalk and improve several thousand times, compares ordinary electric capacity pen and improves hundred times, great improvement life, saving social resource.
