储墨结构3还包括嵌设于通光通道11内且一侧与抵压镜片2抵顶的支撑环31，储墨部4包括在支撑环31的与抵压镜片2承靠侧凹陷形成的储墨槽41，储墨槽41的延伸方向与支撑环31一致，墨水存储于储墨槽41内。具体的，在本实现方式中，支撑环31的靠近抵压镜片2侧设置多圈环形的储墨槽41，具体数量根据实际情况确定，各储墨槽41同轴，且相邻的储墨槽41之间的距离相等，各储墨槽41的深度和宽度相等，储墨槽41可以是V型槽、矩形槽或梯形槽等，在前安装的镜片安装完成后，将支承环安装到通光通道11内，然后把墨水盛装于各储墨槽41内，之后把抵压镜片2装配在支撑环31的顶侧，储墨槽41内的墨水即可覆盖抵压镜片2的抵顶面，并且墨水可以流到支撑环31靠近光轴的内表面及支撑环的外侧面和镜头筒1的内壁之间，从而使抵压镜片2的抵顶面、支撑环31的上表面、支撑环31的内外表面及镜头筒1的对应侧面获得消除杂光的效果。为了使墨水能在抵压镜片2的抵顶面上覆盖更加全面而均匀，从而获得更好的吸收杂光的效果，在本实现方式中，抵压镜片2的抵顶面进行消光处理，消光处理可以采用打磨、喷涂消光漆等方式实现。
结合图3-6；在本实施例的第二种实现方式中：
储墨结构3还包括嵌设于通光通道11内且一侧与抵压镜片2抵顶的支撑环31，储墨部4包括在支撑环31的与抵压镜片2承靠侧凹陷形成的储墨槽41，储墨槽41的延伸方向与支撑环31一致，墨水存储于储墨槽41内，储墨部4还包括嵌设于储墨槽41内的储墨环42，储墨槽41的延伸方向与支撑环31一致，储墨环42为多孔弹性结构，墨水存储于储墨环42内，储墨环42舒张状态时高度高于储墨槽41的槽口。具体的，在本实现方式中，支撑环31的顶侧设置一圈储墨槽41，储墨槽41内嵌设一个储墨环42，储墨环42可以采用海绵、泡棉等材料，从而实现对墨水的吸取，以及被挤压时释放墨水，由于储墨环42的高度高于储墨槽41的槽口，除了储墨槽41内可以存储墨水外，储墨环42高出的部分也能吸储墨水，因此，将抵压镜片2装配到支撑环31上时，储墨环42内的墨水会析出，使抵压镜片2的抵压面有足量的墨水覆盖，提高墨水覆盖的效果。为了使墨水能在抵压镜片2的抵顶面上覆盖更加全面而均匀，从而获得更好的吸收杂光的效果，在本实现方式中，抵压镜片2的抵顶面进行消光处理，消光处理可以采用打磨、喷涂消光漆等方式实现。抵压镜片2抵顶储墨环42后，储墨环42内的墨水会流到储墨槽41并流出，从而覆盖抵压镜片2的抵顶面，并且墨水可以流到支撑环31靠近光轴的内表面及支撑环的外侧面和镜头筒1的内壁之间，从而使抵压镜片2的抵顶面、支撑环31的上表面、支撑环31的内外表面及镜头筒1的对应侧面获得消除杂光的效果。在本实现方式中的其他替代方式中，储墨槽41可以设置同轴的两圈、三圈、四圈等，每个储墨槽41内均嵌置一对应的储墨环42，从而进一步地确保墨水覆盖效果。
结合图7-10，在本实施例的第三种实现方式中：
储墨结构3还包括收容于通光通道11内且位于抵压镜片2一侧的支撑环31，镜头结构还包括收容于通光通道11内且位于支撑环31的远离抵压镜片2侧的配合镜片5，储墨部4为设置于支撑环31、镜头筒1的内壁及配合镜片5之间的储墨环42。
具体的，在本实现方式中，将在前安装的镜片安装完成后，把配合镜片5安装到通光通道11内，此时配合镜片5的外侧面和镜头筒1的内壁围合形成储墨槽41，之后将吸储墨水的储墨环42嵌置于储墨槽41内，然后把支撑环31安装到通光通道11内，此时支撑环31位于储墨环42的顶侧，最后把抵压镜片2安装到支撑环31顶侧，在抵压镜片2的抵压下，支撑环31对储墨环42挤压，从而将储墨环42内的墨水挤出，墨水会覆盖配合镜片5的外侧面及镜头筒1与配合镜片5对应的内壁面，使各被墨水覆盖的表面获得吸收杂光的效果。为了获得更好的吸收杂光的效果，储墨结构3还可以包括设置于储墨环42和支撑环31之间的遮光片33，在装配过程中，由遮光片33对储墨环42进行挤压，挤压过程中，遮光片33的底面也会被墨水覆盖而获得吸收杂光的效果。
结合图11-14，在本实施例的第四种实现方式中：
镜头结构还包括收容于通光通道11内且与抵压镜片2的相邻的配合镜片5，配合镜片5靠近抵压镜片2的一侧朝远离抵压镜片2的方向凹陷形成的缺口43，储墨结构3还包括设置于缺口43内的遮光片33，储墨部4为承靠于遮光片33的靠近抵压镜片2的一侧的储墨环31，抵压镜片2抵压于储墨环31。
具体的，在本实现方式中，缺口43与配合镜片5的外侧不相邻，储墨结构3还包括承靠于缺口43的底部的遮光片33，储墨环42承靠于遮光片33远离缺口43的底部的一侧，抵压镜片2的与缺口43对应处凸出形成压坎21，压坎21伸入缺口43内并抵顶于储墨环42。
将在前安装的镜片及配合镜片5安装到通光通道11内之后，把遮光片33放置在缺口43的底部，然后把吸储墨水的储墨环42放置在遮光片33的顶侧，之后将抵压镜片2安装到配合镜片5的顶侧，此时，抵压镜片2上的压坎21伸入到缺口43内并对储墨环42进行挤压，储墨环42内的墨水挤压出后可以覆盖遮光片33的表面，使该表面获得吸收杂光的效果。
结合体图15-18，在本实施例的第五种实现方式中：
镜头结构还包括收容于通光通道11内且与抵压镜片2相邻的配合镜片5，配合镜片5靠近抵压镜片2的一侧的周缘处朝远离抵压镜片2的方向凹陷形成缺口43，储墨结构3还包括设置于缺口43和抵压镜片2之间的储墨环42。
具体的，在本实现方式中，缺口43位于配合镜片5的边缘处，即缺口43与配合镜片5的边缘相邻，抵压镜片2的与缺口43对应处朝远离配合镜片5的方向凹陷形成压口22，压口22的底面抵顶于储墨环42。在一些替代方式中。
将在前安装的镜片及配合镜片5安装到通光通道11内之后，把吸储墨水的储墨环42放置在缺口43内，之后将抵压镜片2安装到配合镜片5的顶侧，此时配合镜片5的压口22会挤压储墨环42，使储墨环42内的墨水被挤出到缺口43内并从缺口43的边缘流到配合镜片5的外侧面和镜头筒1的内壁面，使配合镜片5的外侧面、镜头筒1对应处的内壁面覆盖墨水而具有吸收杂光的效果。
通过储墨结构3和储墨部4的不同设置方式，可以使镜头结构中不同的位置覆盖墨水，从而使相应位置获得吸收杂光的效果，本方案部件装配简单，能够满足不同位置的杂光需求。
本实施例中并不限定抵压镜片2和配合镜片5的具体位置，即抵压镜片2可以是镜头结构中任一位置的镜片，具体位置可以根据需要涂墨的位置设置。
在本实施例中，结合图19，提供一种涂墨方法，应用于如上任意一种镜头结构，包括：
S1、调整镜头筒1的角度和位置，使镜头筒1的物侧面朝向重力方向；
S2、将储墨结构3及镜头结构中较储墨结构3更靠近遮光筒1的物侧面的部件依次安装到通光通道11内；
S3、将抵压镜片2安装到储墨结构3的远离镜头筒1的物侧面的一侧并使抵压镜片2抵顶储墨结构3，使储墨部4中的墨水受挤压流出。
通过抵压镜片2挤压储墨结构3而使存储墨水的储墨部4受到挤压，使储墨部4内的墨水流出后覆盖对应部件的表面，从而使相应的表面获得吸收杂光的效果，本方案部件装配简单，加工过程便捷，能够提高涂墨效率。
以上所述的仅是本发明的实施方式，在此应当指出，对于本领域的普通技术人员来说，在不脱离本发明创造构思的前提下，还可以做出改进，但这些均属于本发明的保护范围。
