AI Technical Summary
Technical Problem
[0004]但是现有的白板笔存在以下技术问题：利用笔杆1a与气压平衡塞3a形成墨腔7a，笔杆1a通常做成不可拆卸的结构，以避免笔杆1a拆装时墨水泄露；这样导致笔杆1a内部零件损坏时，无法拆装笔杆1a进行更换，仍然容易造成浪费
Benefits of technology
本实用新型白板笔通过在气压平衡塞上设置单独的墨囊来存储墨水，使得墨水无需依赖笔杆进行存储；将笔杆设置为可拆式连接的上笔杆和下笔杆，可对笔杆进行拆装；在设置墨囊后对笔杆进行拆装不会影响墨水的存储，从而不易造成墨水泄露；而且可拆式结构的笔杆方便内部部件的拆装，从而在某些部件损坏时，不用丢弃整支笔，而是可以通过更换相应的部件达到重复使用的目的，不易造成浪费。
