Active electromagnetic pen

Abstract

The invention discloses an active electromagnetic pen which comprises a pen holder, and the pen holder is provided with an installation cavity used for containing a pen core. The electromagnetic pen device is located in the mounting cavity, the electromagnetic pen device comprises a pen framework, a pen refill, an induction coil, a circuit board and a power supply unit, and the electromagnetic pen device can wirelessly transmit electromagnetic signals when acting; the switch module is located in the installation cavity and serves as a switch of the electromagnetic pen device, and when the refill generates displacement, the switch module can be triggered so that the electromagnetic pen device can be kept in an on or off state; the pen cap detachably covers the open end of the mounting cavity, an avoiding hole communicated with the mounting cavity is formed in the pen cap, the pen refill can abut against the pen cap and the cavity wall face of the mounting cavity, and part of the pen refill extends out of the avoiding hole; the active electromagnetic pen has the advantage that the refill of the active electromagnetic pen can be used for replacing a traditional gel pen refill at will.

Description

technical field [0001] The invention relates to the technical field of electromagnetic pens, in particular to an active electromagnetic pen, the pen core of which can be replaced by a traditional gel pen core at will. Background technique [0002] The writing type electromagnetic pen is a pen tool that can be used as a general ink pen for writing and has the function of an electromagnetic pen. The writing electromagnetic pen is often used in conjunction with a digital receiving board or a handwriting board during the writing process. In addition to directly writing on ordinary paper as a pen tool, the electromagnetic pen can also store the written content as digital data through the digital receiving board or handwriting board at the same time, so that the user can immediately understand the content of the note or smear through the paper, and the digital data is It is convenient for future organization and editing. Because this type of writing electromagnetic pen is not ...

Problems solved by technology

In order to overcome and prevent this problem, some manufacturers have improved the structure of the electromagnetic pen, so that users can start the writing electromagnetic pen according to the writing habits of ordinary pens. For example, the invention patent of publication number CN101311000 mentioned a retractable writing electromagnetic pen. ; But the above improvement can not solve the problem that the refill can replace the traditional gel pen refill
