Description

现有涂写领域中，通常采用由薄膜包覆纤维束而形成的卷包芯作为储液材料。用卷包芯作为储液材料的涂写工具的出液量会随着使用而逐渐降低，并且卷包芯有残液量大的缺点。In the existing graffiti field, a roll-wrapped core formed by wrapping a fiber bundle with a film is usually used as a liquid storage material. The liquid output of the scribbling tool using the roll-wrapped core as the liquid storage material will gradually decrease with use, and the roll-wrapped core has the disadvantage of a large amount of residual liquid.
采用塑料调节器的直液式的涂写工具出墨量稳定，残墨量少，但通常因为调节器的质量波动而产生漏液问题。这种涂写工具因为涂写头离墨水管较远并且两者之间只用引水芯传导液体，如果涂写头朝上放置一段时间或涂写头朝上使用，容易导致涂写头缺少液体而影响功能。Direct-liquid graffiti tools with plastic regulators have a stable ink output and a small amount of residual ink, but usually cause liquid leakage problems due to fluctuations in the quality of the regulator. Because the scribbling tool is far away from the ink tube and only the water core is used to conduct the liquid between the two, if the scribbling head is placed upward for a period of time or used with the scribbling head upward, it will easily cause the scribbling head to lack liquid and affect the function.

The lower end surface of the ventilating liquid guiding element casing 303 It is close to or flush with the lower end surface of the air-permeable liquid-guiding element body 300 .
本实施例中，涂写工具1在储液腔40下方设置缓冲体80。缓冲体80和中继导液元件70通过透气导液元件30和涂写头50压缩粘结纤维或薄膜包覆的纤维束中的部分纤维形成。也就是说，透气导液元件30和涂写头50压缩粘结纤维或薄膜包覆的纤维束中的部分纤维形成中继导液元件70，其余部分形成缓冲体80。因此本实施例中，中继导液元件70较缓冲体80具有较高的密度和毛细力。In this embodiment, the scribbling tool 1 is provided with a buffer body 80 under the liquid storage chamber 40 . The buffer body 80 and the intermediate fluid-guiding element 70 are formed by the air-permeable fluid-guiding element 30 and the applicator 50 compressing the bonded fibers or part of the fibers in the film-coated fiber bundle. That is to say, the air-permeable liquid-conducting element 30 and the doub head 50 compress the bonded fibers or part of the fibers in the film-wrapped fiber bundle to form the relay liquid-conducting element 70 , and the rest form the buffer body 80 . Therefore, in this embodiment, the relay liquid guiding element 70 has higher density and capillary force than the buffer body 80 .
具体而言，在本实施例中，透气导液元件30和涂写头50共轴设置，也就是说，透气导液元件30和涂写头50的中轴线重合。透气导液元件30从上向下压缩粘结纤维或薄膜包覆的纤维束中的部分纤维，涂写头50从下向上压缩粘结纤维或薄膜包覆的纤维束中的部分纤维。由此，在粘结纤维或薄膜包覆的纤维束的中部形成的密度较高的压缩部作为中继导液元件70，其余部分作为缓冲体80。Specifically, in this embodiment, the air-permeable liquid-guiding element 30 and the writing head 50 are arranged coaxially, that is, the central axes of the air-permeable liquid-guiding element 30 and the writing head 50 coincide. The air-permeable liquid-guiding element 30 compresses the bonded fibers or some fibers in the film-coated fiber bundle from top to bottom, and the applicator 50 compresses the bonded fibers or some fibers in the film-coated fiber bundle from bottom to top. Thus, the compressed portion with higher density formed in the middle of the bonded fiber or film-wrapped fiber bundle serves as the relay fluid guiding element 70 , and the rest serves as the buffer body 80 .
透气导液元件30的透气导液元件流体腔道301连通中继导液元件70和储液腔40，并且中继导液元件70封堵与之连通的透气导液元件流体腔道301的端口。中继导液元件70将液体从透气导液元件30传导至涂写头50。本实施例的涂写工具1的工作原理与实施例1相同。The air-permeable liquid-guiding element fluid lumen 301 of the air-permeable liquid-guiding element 30 communicates with the relay liquid-guiding element 70 and the liquid storage chamber 40, and the relay liquid-guiding element 70 blocks the port of the air-permeable liquid-guiding element fluid lumen 301 communicating therewith . Relay fluid conducting element 70 conducts liquid from gas permeable fluid conducting element 30 to applicator head 50 . The working principle of the graffiti tool 1 of this embodiment is the same as that of Embodiment 1.
当外部温度升高或压力下降时，储液腔40中的空气膨胀，液体经透气导液元件30导出至中继导液元件70，再从中继导液元件70传导至缓冲体80中暂时储存。当外界温度或压力恢复正常时，由于中继导液元件70封堵与之连通的透气导液元件流体腔道301的端口，中继导液元件70中的液体优先于空气经中继导液元件70和透气导液元件30返回储液腔40；同时缓冲体80中的液体传导至中继导液元件70，并经透气导液元件30返回储液腔40，从而减少涂写工具1在外界温度升高或压力下降时的泄漏风险。When the external temperature rises or the pressure drops, the air in the liquid storage chamber 40 expands, and the liquid is exported to the relay liquid guide element 70 through the air-permeable liquid guide element 30, and then conducted from the relay liquid guide element 70 to the buffer body 80 for temporary storage . When the external temperature or pressure returns to normal, since the relay fluid guiding element 70 blocks the port of the gas permeable fluid guiding element fluid lumen 301 connected thereto, the liquid in the relay fluid guiding element 70 is preferentially guided through the relay rather than the air. The element 70 and the air-permeable liquid-guiding element 30 return to the liquid storage chamber 40; at the same time, the liquid in the buffer body 80 is conducted to the relay liquid-guiding element 70, and returns to the liquid-storage chamber 40 through the air-permeable liquid-guiding element 30, thereby reducing the impact of the graffiti tool 1 on the outside. Risk of leakage when temperature rises or pressure drops.

This embodiment is similar in structure to the fourth embodiment, and the same parts as the fourth embodiment will not be repeated in the description of this embodiment. In this embodiment, the sleeve 303 of the gas-permeable liquid-guiding element is configured as a structure that narrows from the upper opening to the lower opening, for example, it may be a stepped structure that is wide at the top and narrow at the bottom in the longitudinal section view. Thus, the sleeve 303 of the air-permeable liquid-conducting element can compress the part of the fiber of the buffer body 80 close to the air-permeable liquid-conducting element 30 . Since this part of the compressed fiber is close to the relay liquid guiding element 70 , it is beneficial for the liquid in the buffer body 80 to transfer to the relay liquid guiding element 70 .
同理，涂写头50***缓冲体80的部分也可以设置为从下部向上部变窄的结构(未图 示)，由此，可以压缩缓冲体80中靠近涂写头50的部分纤维，这些部分压缩的纤维靠近涂写头50，有利于液体向涂写头50传递。In the same way, the part where the graffiti head 50 is inserted into the buffer body 80 can also be set to a structure that narrows from the bottom to the top (not shown in the figure). (shown), thus, part of the fibers in the buffer body 80 close to the painting head 50 can be compressed, and these partially compressed fibers are close to the painting head 50, which facilitates the transfer of liquid to the painting head 50.

The scribbling tool 1 further includes a gas-permeable fluid-guiding element sleeve 303 at least partially covering the gas-permeable fluid-guiding element body 300 , and the gas-permeable fluid-guiding element sleeve 303 is used to fix the gas-permeable fluid-guiding element body 300 . The lower end surface of the air-permeable liquid-guiding element sleeve 303 is close to or flush with the lower end surface of the air-permeable liquid-guiding element body 300 .
在本实施例中，涂写工具1在储液腔40下方设置缓冲体80。如图12所示，缓冲体和中继导液元件70通过透气导液元件30和涂写头50压缩海绵的一部分形成，中继导液元件70较缓冲体80具有较高的密度和毛细力。In this embodiment, the graffiti tool 1 is provided with a buffer body 80 under the liquid storage chamber 40 . As shown in FIG. 12 , the buffer body and the relay fluid-guiding element 70 are formed by compressing a part of the sponge with the air-permeable fluid-guiding element 30 and the applicator 50 , and the relay fluid-guiding element 70 has higher density and capillary force than the buffer body 80 .
透气导液元件30的透气导液元件流体腔道301连通中继导液元件70和储液腔40，并且中继导液元件70封堵与之连通的透气导液元件流体腔道301的端口。中继导液元件70将液体从透气导液元件30传导至涂写头50。本实施例的涂写工具1的工作原理与实施例1相同。The air-permeable liquid-guiding element fluid lumen 301 of the air-permeable liquid-guiding element 30 communicates with the relay liquid-guiding element 70 and the liquid storage chamber 40, and the relay liquid-guiding element 70 blocks the port of the air-permeable liquid-guiding element fluid lumen 301 communicating therewith . Relay fluid conducting element 70 conducts liquid from gas permeable fluid conducting element 30 to applicator head 50 . The working principle of the graffiti tool 1 of this embodiment is the same as that of Embodiment 1.
当外部温度升高或压力下降时，储液腔40中的空气膨胀，液体经透气导液元件30导出至中继导液元件70，再从中继导液元件70传导至缓冲体80中暂时储存。当外界温度和压力恢复正常时，由于中继导液元件70封堵与之连通的透气导液元件流体腔道301的端口，中继导液元件70中的液体优先于空气经中继导液元件70和透气导液元件30返回储 液腔40；同时缓冲体80中的液体传导至中继导液元件70，并经透气导液元件30返回储液腔40，从而减少涂写工具1在外界温度升高或压力下降时的泄漏风险。When the external temperature rises or the pressure drops, the air in the liquid storage chamber 40 expands, and the liquid is exported to the relay liquid guide element 70 through the air-permeable liquid guide element 30, and then conducted from the relay liquid guide element 70 to the buffer body 80 for temporary storage . When the external temperature and pressure return to normal, since the relay fluid guiding element 70 blocks the port of the gas-permeable fluid guiding element fluid cavity 301 connected thereto, the liquid in the relay fluid guiding element 70 is preferentially guided through the relay rather than the air. The element 70 and the gas permeable liquid conducting element 30 are returned to the storage Liquid chamber 40; at the same time, the liquid in the buffer body 80 is conducted to the relay liquid guide element 70, and returns to the liquid storage chamber 40 through the air-permeable liquid guide element 30, thereby reducing the leakage risk of the graffiti tool 1 when the external temperature rises or the pressure drops .
