The utility model discloses a new type of pressure-assisted pen core device, which comprises a medical syringe and an annular tube integrally moulded into the upper port of a medical syringe. A U-shaped groove is arranged on the annular tube, a wedge-shaped pressing head is clamped in the U-shaped groove, and a wedge-shaped pressing head is fixedly connected with the plunger rod of the medical syringe, so that the column in the medical syringe can be driven when the wedge-shaped pressing head is pressed The plug bar exerts pressure on the core of the pen to make the liquid flow out and write on the paper; among them, the wedge press head and the installation surface of the U-groove can move up and down by setting a limit block and a backstop structure, which makes the wedge press head have obvious pressure overlap every time it moves up or down, and has the advantages of easy operation and high precision of pressure control, compared with the existing pressure assistance. The pen-aid core device avoids the uneven pressure caused by adjusting one left one right one after another and the troublesome operation caused by rotating screw, which is time-consuming and time-consuming, and the inaccurate pressure value.

技术介绍
近几年,由于纸具有来源广泛、成本低廉、可随身携带、任意折叠、循环利用等特性,以纸为基底衍生出的电子传感器得到了快速的发展。传统在纸上制备电子传感器的方法有溅射镀膜、喷墨打印以及喷枪喷涂。但是以上几种方式涉及专业仪器的使用,操作复杂、代价昂贵并且通常需要预先对导电浆进行稀释等预处理,容易导致在浆液纸表面扩散渗透,难以精确控制传感器线路的均一性,并对传感器的导电性能有较大的影响。为了克服上述问题,Russo等人于2011年开发出了装有导电浆的笔芯装置[AnalisaRusso,BokYeopAhn,JacobJ.Adams,EricB.Duoss,JenniferT.Bernhard,andJenniferA.Lewis.Pen-on-PaperFlexibleElectronics.AdvancedMaterials,2011,23,3426–3430]。该装置通过将稀释到特定浓度和粘度的银浆注入到笔芯内,然后直接在纸上画出所需的电子传感器图案,经加热处理后便能形 ...
