Description

一种涂写工具 技术领域
本发明涉及一种涂写工具，特别涉及控制书写工具和化妆品中各类液体释放的技术领域。
背景技术
在控制液体释放的技术领域中，多孔材料得到了广泛的应用，如在记号笔中，使用多孔材料作为吸收和容纳液体的材料。现有技术中，最常用的多孔材料是由薄膜包覆纤维束而形成的卷包芯，使用时装入外壳并插入涂写头，卷包芯两端与大气连通，以便注入液体时空气向两端排出、液体向两端扩散，也便于液体释放。但是卷包芯的出液量会随着使用时间的增加而逐渐降低，并且卷包芯有残液量大的缺点。
在控制液体释放的技术领域中，另一种常用的技术是采用引水芯传导液体，并用翅片组来控制液体释放，适合于小出墨量的应用，如水性宝珠笔，这种引水芯和翅片组结合的技术对制造精度要求很高，零部件稍有质量波动或遇到温差和压差等异常环境变化时液体容易泄漏。申请号为201510018984.0的专利文献公开了一种直液式书写装置，该技术在墨水管和笔头之间设置了一个调节部，利用调节部中非常精密的间歇来控制墨水释放，这种液体释放技术较好地解决了卷包芯类涂写工具的问题，并有利于大出液量的应用，但调节部的设计较为复杂，并且调节部中间歇尺寸控制要求极为精密，制造成本较高。这两种技术中因为笔头离墨水管较远并且两者之间只用引水芯传导液体，造成共同的缺陷是：如果笔头朝上放置一段时间或笔头朝上使用，均容易导致笔头部分缺少墨水而影响功能。
发明内容
为解决传统卷包芯类涂写工具和现有的一些直液式涂写工具存在的问题，本发明提出一种涂写工具，包括涂写头、与外界大气连通的缓冲体、气液交换器和给气液交换器供给液体的储液管，气液交换器具有引水芯、包覆在引水芯外周壁上的液封管和设置在引水芯和液封管之间的气液通道；缓冲体包覆在液封管的外周壁上，液封管的毛细压比缓冲体的毛细压大30％以上。
进一步，引水芯外周壁上设置凹槽，凹槽与液封管内周壁之间形成气液通道。
进一步，液封管由多孔材料制成。
进一步，当气液通道作为导气通道时，导气通道横截面的最大内切圆直径为0.1-0.8mm。
进一步，缓冲体由多孔材料制成。
进一步，引水芯穿过液封管下端与涂写头连接。
进一步，储液管底部设置套管。
进一步，气液交换器下方设置保护体，保护体的毛细压不大于缓冲体的毛细压。
进一步，缓冲体和液封管一体成型，液封管的外周壁和缓冲体的内周壁粘结。
进一步，涂写头插入气液交换器并与液封管的部分内壁连接。
根据本发明的技术方案，能有效地控制液体释放，出液流畅稳定，并能有效地防止异常状况下液体泄漏；结构简单、制造方便。

具体实施方式
以下由特定的具体实施例说明本发明的实施方式，本领域技术人员可由本说明书所揭 示的内容轻易地了解本发明的其他优点及功效。虽然本发明的描述将结合较佳实施例一起介绍，但这并不代表此发明的特征仅限于该实施方式。恰恰相反，结合实施方式作发明介绍的目的是为了覆盖基于本发明的权利要求而有可能延伸出的其它选择或改造。为了提供对本发明的深度了解，以下描述中将包含许多具体的细节。本发明也可以不使用这些细节实施。此外，为了避免混乱或模糊本发明的重点，有些具体细节将在描述中被省略。
另外，在以下的说明中所使用的“上”、“下”、“前”、“后”，不应理解为对本发明的限制。本发明中“下”“前”是指涂写头1一端，“上”“后”是指储液管一端。
本发明中提到的正常状况或者未特别注明的状况通常是指室温和一标准大气压的情况，异常状况是指外界温度或压力偏离正常状况的情况。本发明中毛细压P的定义为当足够长度(一般要求2-15cm)的多孔体(液封管或缓冲体)，在正常状况下，一端刚好接触水平的液面并竖直放置30分钟后液体上升高度h产生的压强，
P＝ρgh,
其中ρ为液体的密度，g为重力加速度，h为液体上升高度
液体上升高度h的测试方法在本发明中定义如下：
1)将长度为H的多孔体放入液体中吸液至饱和，测试其饱和吸液重量W 0，
2)用同样的多孔体和同样的液体，将多孔体的一端刚好接触液面并竖直放置30分钟，测试其吸液重量为W，
3)计算h值为：h＝(W/W 0)x H
如图1至图6所示，根据本发明的涂写工具，包括涂写头1、与外界大气连通的缓冲体2、气液交换器3和给气液交换器3供给液体的储液管4，气液交换器3具有引水芯31、包覆在引水芯31外周壁上的液封管32和设置在引水芯31和液封管32之间的气液通道30；缓冲体2包覆在液封管32的外周壁上，液封管32的毛细压比缓冲体2的毛细压大30％以上。
<气液交换器>
根据本发明的涂写工具,气液交换器3具有引水芯31、包覆在引水芯31外周壁上的液封管32和设置在引水芯31和液封管32之间的气液通道30。
<引水芯>
本发明的引水芯31可以由纤维粘结制成，如由聚酯纤维、亚克力纤维 等粘结制成。并且，引水芯31外周壁上设置凹槽，凹槽与液封管32内周壁形成气液通道30。即在引水芯31的外周壁上，从一端延伸至另一端设置一条或多条凹槽，作为气液通道30。当仅设置一条凹槽时，该凹槽作为向储液管4导通气路的导气通道，引水芯31作为从储液管4向涂写头1传输液体的导液通道。当设置多条凹槽时，部分凹槽也可以作为从储液管4向涂写头1传输液体的导液通道。
本发明中的引水芯31也可以由表面能被液体浸润的塑料制成，如聚甲醛、尼龙等，塑料引水芯31需在其表面设置两条或以上的凹槽，作为气液通道30，其中至少一条凹槽作为向储液管4导通气路的导气通道，其它的凹槽则作为从储液管4向涂写头1传输液体的导液通道。
<液封管>
本发明的液封管32由多孔材料制成。制成液封管32的多孔材料可以为滤膜或纤维。液封管32的壁厚为0.1-5mm，如0.1mm、0.5mm、1mm、2mm、5mm。壁厚较薄的液封管32可以用滤膜制作，壁厚较厚的液封管32可以用单组份纤维或双组份纤维粘结制成。较薄壁的液封管32对液体的容量小，有利于更充分地利用和释放液体，减少残留量；较厚壁的液封管32对液体的容量大，有利于在气液交换器3中保留较多液体，即使在涂写头1朝上使用时也具有良好的液体释放性能。
液封管32包覆在引水芯31外周壁上。液封管32可以部分包覆在引水芯31的外周壁上，也可以全部包覆引水芯31的外周壁上。包覆的面积可以根据设计的需要进行合理选择。
液封管32在吸收一定量液体后使气体不能在径向穿过液封管32，从而将引水芯31及气液通道30与缓冲体2隔离，在这种情况下，储液管4和外界只能通过气液通道30交换气体，而无法从缓冲体2经液封管32交换气体。吸收液体后的液封管32内壁与引水芯31及其表面的凹槽之间形成气液通道30，并在气液通道30的大部分空间中充满液体，从而使导气通道30被液封成多段小气泡。当液体从储液管4经气液交换器3导出时，储液管4内和外界的压差增加，推动气液通道30中的气泡向储液管4移动并进入储液管4，使储液管4与外界的压差减小直至平衡，同时气液通道30中形成新的液封段和小气泡。液封管32的毛细压比缓冲体2的毛细压大30％以上，使得缓冲体2难以在正常情况下从液封管32吸收液体。
<气液交换器>
本发明的气液交换器3包括引水芯31和液封管32，引水芯31的全部或部分外周壁被液封管32包覆。
气液交换器3的引水芯31外周壁上的凹槽与液封管32内周壁形成气液通道30，并且与环境大气连通。根据涂写工具的使用要求和其中的液体性质，当气液通道30作为导气通道时，导气通道横截面的最大内切圆直径为0.1-0.8mm。最大内切圆直径不同的导气通道具有不同的毛细力，以控制导气时的液封强度。最大内切圆直径较小则导气量小，适合于出液量较小的涂写工具；最大内切圆直径较大则导气量大，适合于出液量大的涂写工具。
气液交换器3中还设置有导液通道。用纤维制作的引水芯31本身可以作为导液通道；引水芯31表面的凹槽或凹槽与液封管32内壁也可以形成导液通道。当涂写工具中使用的液体含有较大的颗粒时，比如使用了珠光墨水或金属墨水，有凹槽的导液通道尤为重要，因为没有凹槽的普通引水芯31会全部或部分过滤液体中的颗粒。
<缓冲体>
缓冲体2包覆在液封管32的外周壁上，液封管32的毛细压比缓冲体2的毛细压大30％以上。
缓冲体2可以部分包覆在液封管32的外周壁上，优选将液封管32的外周壁全部包覆。
本发明的缓冲体2由多孔材料制成，并与环境大气连通。制成缓冲体2的多孔材料可以为海绵或纤维，缓冲体2长度和壁厚可以根据涂写工具的内部空间设置。根据涂写工具中使用的液体和使用要求制作具有适当毛细压的缓冲体2。
液封管32的毛细压比缓冲体2的毛细压大30％以上，并且在正常状况下缓冲体2几乎不从液封管32吸收液体。缓冲体2的内壁和液封管32的外壁连接，如果发生异常状况而使液封管32中液体含量过高，则缓冲体2吸收液封管32中过多的液体，这样可以防止液体从涂写头1泄漏。当异常状况消失后，缓冲体2中的液体回传给液封管32，并经导液通道返回储液管4。为使缓冲体2具有上述性能，缓冲体2的密度为0.03-0.20克/厘米 3，如果用纤维制作缓冲体2，纤维的纤度为0.5-30旦比较合适。
<涂写头>
本发明的涂写头1可以与穿过液封管32的引水芯31连接，也可以插入气液交换器3并与液封管32的部分内壁连接。还可以将引水芯31延长作为涂写头1。
<储液管>
本发明的涂写工具中，储液管4是储存液体的部件。储液管4的底部可以设置向上或向下的套管62，将套管62插入气液交换器3并与液封管32的内壁紧密接触，或将液封管32和引水芯31插入套管62，这样有利于固定气液交换器3、并防止液体泄漏。可以采用可更换的储液管4，有利于重复利用外壳6等部件，减少资源浪费。替换型的储液管4可采用螺接、卡接等多种方式连接到涂写工具中。

在本实施例中，引水芯31的另一端穿过液封管32后，再穿过保护体5，然后插入涂 写头1中。
在极端的异常情况下，比如从低海拔地区携带涂写工具到高海拔地区，或在高空飞行的飞机上打开涂写工具，因储液管4内、外部的极端气压差，导致从储液管4迅速导出的液体无法及时被缓冲体2吸收而泄漏。这种情况下，保护体5可以吸收从气液交换器3快速逸出的液体。在异常情况消除后，保护体5中暂存的液体会通过引水芯31传输给涂写头1或者由液封管32吸收。
根据本实施例的涂写工具，可以应用于眼线笔。根据本实施例的涂写工具，由于作为气液通道30的凹槽的数量为3条，其中，至少有一条可以作为导液通道，则眼线液中的颗粒可以通过凹槽输送至涂写头1，而不会被引水芯31过滤掉。
