Three-dimensional dust-free foam chalk

The three-dimensional dust-free foam chalk comprises a pen holder shell, a pen point shell arranged at the bottom of the pen holder shell and an end cover body arranged at the top of the pen holder shell, the pen holder shell is of a hollow structure, a liquid compressed foam bottle is arranged in the pen holder shell, and a foam channel corresponding to the liquid compressed foam bottle is arranged in the pen point shell; chalk is replaced by compressed foam, the problem that dust is generated by the chalk is fundamentally solved, and the problem that hands are polluted by traditional chalk can be avoided by arranging the pen holder shell and the pen point shell. And the liquid compressed foam bottle can be detached and replaced, use of multiple colors can be achieved, convenience and diversity are achieved, meanwhile, the laser lamp and photographing functions are further achieved, and practicability is higher. 本发明公开了一种立体无尘泡沫粉笔，包括笔杆壳体、设置于笔杆壳体底部的笔头壳体以及设置于笔杆壳体顶部的端部盖体，所述笔杆壳体为中空结构其内设置液态压缩泡沫瓶，所述笔头壳体内设置与液态压缩泡沫瓶对应
