Description

一种白板笔 技术领域
本实用新型涉及书写文具技术领域，更具体地说，涉及一种白板笔。
背景技术
白板笔是一种在白板上进行书写的文具，类似于黑板的粉笔。白板笔的墨水为油墨，可写在光滑的白板上，并可使用白板擦擦掉。
目前，白板笔按结构分类可以分为一次性白板笔、可加水白板笔、直液式白板笔、气压式白板笔等。一次性白板笔使用卷包芯储墨，由于尺寸限制，一般卷包芯储墨量较少，书写长度受限制且较短，书写至油墨干枯后无利用价值而直接报废。可加水白板笔一般采用直液式加墨，因受笔尖需连接阀门限制，一般前端采用海绵储存墨水，海绵间隙大储墨量极少，需经常性按压笔尖出水保证书写，导致前端负荷过大出现漏水。
综上所述，如何延长书写长度的同时减少漏水现象的发生概率，成为本领域技术人员亟待解决的技术问题。
发明内容
有鉴于此，本实用新型的目的在于提供一种白板笔，以实现延长书写长度的同时减少漏水现象发生的发生概率目的。
为实现上述目的，本实用新型提供如下技术方案：
一种白板笔，包括前笔杆和与所述前笔杆可拆卸连接的后笔杆，其中，所述后笔杆内部为盛放墨水的腔体，所述前笔杆内部设置有露出所述前笔杆的笔 尖，所述前笔杆内部固定有卷包芯和阀门，所述卷包芯中部设置有通孔，所述笔尖设置在所述通孔内，所述阀门的进墨口位于腔体侧，所述阀门的出墨口位于所述卷包芯侧，当所述笔尖位于第一状态时，所述阀门进墨口与出墨口连通，当所述笔尖位于第二状态时，所述阀门进墨口与出墨口非导通。
优选地，上述白板笔中，所述阀门包括大塞、弹簧和顶针，其中，所述大塞的外周固定在所述前笔杆的内壁，所述大塞位于卷包芯侧的开口为所述出墨口，所述大塞位于所述腔体侧的开口为所述进墨口；所述顶针位于所述大塞内，其一端穿过所述进墨口，且所述顶针的另一端与所述笔尖接触并能够密封所述出墨口，所述弹簧设置在所述顶针与所述大塞之间。
优选地，上述白板笔中，所述大塞的进墨口处还设置有用于固定所述弹簧的卡柱。
优选地，上述白板笔中，所述大塞的出墨口处还设置有内塞，所述内塞的外壁固定在所述大塞的内壁，所述大塞在所述内塞配合下完成对出墨口的密封。
优选地，上述白板笔中，所述腔体内还设置有支柱。
优选地，上述白板笔中，所述后笔杆的尾部还设置有备用笔尖。
优选地，上述白板笔中，所述备用笔尖通过后塞密封在所述后盖与所述后笔杆所围成的空间内。
优选地，上述白板笔中，还包括设置在所述前笔杆上的笔帽。
优选地，上述白板笔中，所述前笔杆和所述后笔杆通过螺纹可拆卸连接。
从上述技术方案中可以看出，本实用新型实施例中的白板笔包括前笔杆和与所述前笔杆可拆卸连接的后笔杆，其中，所述后笔杆内部为盛放墨水的腔体，所述前笔杆内部设置有露出所述前笔杆的笔尖，所述前笔杆内部固定有卷包芯和阀门，所述卷包芯中部设置有通孔，所述笔尖设置在所述通孔内，所述阀门 的进墨口位于腔体侧，所述阀门的出墨口位于所述卷包芯侧，当所述笔尖位于第一状态时，所述阀门进墨口与出墨口连通，当所述笔尖位于第二状态时，所述阀门进墨口与出墨口非导通。
上述白板笔在使用时，当笔尖位于第一工作状态时，阀门的进墨口与出墨口导通，位于腔体内的墨水在自身重力的作用白进墨口流向出墨口，并被卷包芯吸收，位于卷包芯内部的笔尖吸收卷包芯内的墨水，从而能够顺利的完成书写动作；当笔尖位于第二工作状态时，阀门的进墨口与出墨口非导通，墨水不会由进墨口流出出墨口，从而防止泄露现象的产生。由于本实用新型实施例中的白板笔，能够通过后笔杆拆卸下来后重新灌入墨水，从而延长了白板笔的书写长度；另外，由于该笔尖由卷包芯进行固定，卷包芯跟海绵相比发生形变小，因此，在书写过程中不易发生泄露问题。
附图说明
为了更清楚地说明本实用新型实施例或现有技术中的技术方案，下面将对实施例或现有技术描述中所需要使用的附图作简单地介绍，显而易见地，下面描述中的附图仅仅是本实用新型的一些实施例，对于本领域普通技术人员来讲，在不付出创造性劳动的前提下，还可以根据这些附图获得其他的附图。
图1本实用新型实施例所提供的一种白板笔爆炸结构示意图；
图2本实用新型实施例所提供的第二种白板笔爆炸结构示意图；
图3本实用新型实施例所提供的第三种白板笔爆炸结构示意图。
其中，图1至图3中：
100为前笔杆、200为笔尖、300为卷包芯、400为阀门、401为大塞、402为顶针、403为弹簧、404为内塞、405为卡柱、500为后笔杆、501为腔 体、502为支柱、600为后盖、601为备用笔尖、700为笔帽。
具体实施方式
有鉴于此，本实用新型提供一种白板笔，以实现延长书写长度的同时减少漏水现象的发生概率的目的。
以下参照附图对实施例进行说明。此外，下面所示的实施例不对权利要求所记载的实用新型内容起任何限定作用。另外，下面实施例所表示的构成的全部内容不限于作为权利要求所记载的实用新型的解决方案所必需的内容。
如图1至图3所示，该白板笔包括前笔杆100和与前笔杆100可拆卸连接的后笔杆500，其中，后笔杆500内部为盛放墨水的腔体501，前笔杆100内部设置有露出前笔杆100的笔尖200，前笔杆100内部固定有卷包芯300和阀门400，卷包芯300中部设置有通孔，笔尖200设置在通孔内，阀门400的进墨口A位于腔体501侧，阀门400的出墨口B位于卷包芯300侧，当笔尖200位于第一状态时，阀门400进墨口A与出墨口B连通，当笔尖200位于第二状态时，阀门400进墨口A与出墨口B非导通。
上述白板笔在使用时，当笔尖200位于第一工作状态时，阀门400的进墨口A与出墨口B导通，位于腔体501内的墨水在自身重力的作用白进墨口A流向出墨口B，并被卷包芯300吸收，位于卷包芯300内部的笔尖200吸收卷包芯300内的墨水，从而能够顺利的完成书写动作；当笔尖200位于第二工作状态时，阀门400的进墨口A与出墨口B非导通，墨水不会由进墨口A流出出墨口B，从而防止泄露现象的产生。由于本实用新型实施例中的白板笔，能够通过后笔杆500拆卸下来后重新灌入墨水，从而延长了白板笔的书写长度；另外，由于该笔尖200由卷包芯300进行固定，卷包芯300跟海绵相比发生形变小， 因此，在书写过程中不易发生泄露问题。
其中实现上述功能的阀门400有很多，本实用新型介绍其中的一种，具体地，该阀门400包括大塞401、弹簧403和顶针402，其中，大塞401的外周固定在前笔杆100的内壁，大塞401位于卷包芯300侧的开口为出墨口B，大塞401位于腔体501侧的开口为进墨口A；顶针402位于大塞401内，其一端穿过进墨口A，且顶针402的另一端与笔尖200接触并能够密封出墨口B，弹簧403设置在顶针402与大塞401之间。
为了保证弹簧403工作过程中的稳定性，大塞401的进墨口A处还设置有用于固定弹簧403的卡柱405。
为了简化加工工艺，大塞401的出墨口B处还设置有内塞404，内塞404的外壁固定在大塞401的内壁，大塞401在内塞404配合下完成对出墨口B的密封。
在更进一步的方案中，为了防止在书写过程中笔尖200移动至前笔杆100的内部，腔体501内还设置有支柱502，当笔尖200移动至前笔杆100内部一定距离时，顶针402与该支柱502相抵，支柱502支撑顶针402，而顶针402又支撑笔尖200，从而达到防止笔尖200过渡的陷入至前笔杆100内。
另外，由于笔尖200长期使用后出现磨损现象，导致书写线幅变大或者纤维开叉无法书写，后笔杆500的尾部还设置有备用笔尖601，可以将该备用笔尖601替换掉笔尖200。
为了防止该备用笔尖601损坏，备用笔尖601通过后塞密封在后盖600与后笔杆500所围成的空间内。
为了防止笔尖200被触碰，弄脏衣物等，还包括设置在前笔杆100上的笔帽700。
前笔杆100和后笔杆500可拆卸连接，可以通过螺纹连接还可以采用过盈配合，优选的采用前者。
对所公开的实施例的上述说明，使本领域专业技术人员能够实现或使用本实用新型。对这些实施例的多种修改对本领域的专业技术人员来说将是显而易见的，本文中所定义的一般原理可以在不脱离本实用新型的精神或范围的情况下，在其它实施例中实现。因此，本实用新型将不会被限制于本文所示的这些实施例，而是要符合与本文所公开的原理和新颖特点相一致的最宽的范围。
