Description

一种石墨烯儿童垫
技术领域
本发明涉及儿童垫技术领域，具体为一种石墨烯儿童垫。
背景技术
儿童垫，大类上来说，属于编织物的一种，即通常所指的“垫子”、“软垫”等，垫子在日常生活中应用非常广泛，按照功能可以分为瑜伽垫、坐垫、地巾等，儿童垫，顾名思义就是应用人群为儿童的垫子，这一类的垫子有一些通性，就是耐磨、耐卷、不掉毛，同时质地软、弹性高，石墨烯是一种由碳原子以sp2杂化轨道组成六角型呈蜂巢晶格的二维碳纳米材料，石墨烯具有优异的光学、电学、力学特性，在材料学、微纳加工、能源、生物医学和药物传递等方面具有重要的应用前景，被认为是一种未来革命性的材料，现代社会将石墨烯材料转入生活用品的制备已经开始发展成趋势。
现代的儿童垫，在实际应用时，往往无法改变其垫子的本质，即儿童垫的柔韧性非常高，铺设在地面或地板等平面上后，能够在地面地板的支撑作用下，保持平整状态，但是其自身不具有任何的结构强度，在使用过程中，儿童垫容易受到儿童的影响，而发生褶皱或隆起，较为影响儿童在上活动时的安全，同时儿童垫的趣味利用性也较差。
发明内容
针对现有技术的不足，本发明提供了一种石墨烯儿童垫，解决了上述背景技术中提出的问题。
为实现以上目的，本发明通过以下技术方案予以实现：一种石墨烯儿童垫，包括垫体、铺设层和垫背，所述垫体包括铺设层、粘附层、弹力层、吸水层、底垫层和垫背，且铺设层、粘附层、弹力层、吸水层、底垫层和垫背依次层叠设置，所述垫体的边缘包裹有封边，且垫体的四角均固定有金属镶块，所述铺设层由拼块相互拼接而成，且拼块的内部中层粘接有石墨烯夹层，所述垫背的表面中间嵌入有大环圈，且大环圈的左右两侧均连接连通有连接管，所述连接管远离大环圈的一端连接有小环圈，且小环圈的末端安装有气嘴，所述大环圈的上下两侧均连接有行动胶管，且行动胶管嵌入在垫背的表面上下两侧边缘，所述行动胶管的外壁等距设置有安装槽，且安装槽的槽内安置有滚轮，所述垫背的正面四角均固定有橡胶吸盘。
可选的，所述大环圈和小环圈均呈螺旋线管状结构，且大环圈和小环圈之间通过连接管构成连通结构，所述安装槽和滚轮均沿行动胶管的方向等距设置。
可选的，所述拼块相互之间形状和尺寸均相吻合，且拼块的外边缘固定有橡胶围沿，所述拼块的上表面中间固定设置有椭圆凸包，且拼块的内部中间竖向贯穿有通口，所述拼块的底面固定有粘布。
可选的，所述粘附层由软胶构成，且软胶的表面分别设置有气口和槽隙，所述槽隙和气口沿软胶的短边方向间隔设置，且气口沿槽隙的方向呈一条直线均匀分布，所述气口与通口之间位置一一对应，且气口与通口之间相连相通。
可选的，所述弹力层由硅胶垫构成，且硅胶垫的表面分别设置有漏水槽和橡胶气囊，所述漏水槽和橡胶气囊沿硅胶垫的短边方向间隔设置。
可选的，所述橡胶气囊各自与气口相连通，且橡胶气囊沿漏水槽的方向均匀设置，所述漏水槽的两侧均固定有网格条，且网格条的内部呈网格状结构。
可选的，所述吸水层由棉纱层构成，且棉纱层的表面分别设置有膨胀胶条和电热丝，所述膨胀胶条和电热丝沿棉纱层的短边方向间隔设置，且膨胀胶条和电热丝之间相互平行。
可选的，所述膨胀胶条的内部嵌入固定有蓄水囊，且蓄水囊与漏水槽之间构成连通结构。
可选的，所述底垫层由海绵基构成，且海绵基的表面等距开设有张拉切槽。
本发明提供了一种石墨烯儿童垫，具备以下有益效果：
1.该石墨烯儿童垫，通过气嘴可以向左右两侧的小环圈中分别注入压缩空气，空气经过小环圈的螺旋线式环绕管路，经过连接管充入到同为螺旋线管的大环圈中，大环圈中的气流又会进入到行动胶管中，在上述充气的作用下，大环圈、小环圈、连接管以及行动胶管内部均处于膨胀状态，在大环圈、小环圈、连接管以及行动胶管内部气压增大的前提下，大环圈、小环圈、连接管以及行动胶管均具有了结构强度，且该强度大小与所注入气体的量的多少有直接关系，即所注入的气体越多，则大环圈、小环圈、连接管以及行动胶管强度越强，从而能够在儿童垫的垫背位置，形成一层加固面，使得整个儿童垫的强度增大，平展在地面地板上时，不容易褶皱隆起，且在大环圈、小环圈、连接管以及行动胶管内部气量充入一定值后，大环圈、小环圈、连接管以及行动胶管的管道体积均会被撑大，尤其是行动胶管，体积胀开后，则会呈现出图6所示的状态，即滚轮会顶出，并能够与地面直接接触，形成整个儿童垫新的支撑结构，当儿童在儿童垫上坐着时，则可以借助这一结构，将该儿童垫转变成滑板，儿童垫不仅具有了结构强度，还具有了可以进行滑动的能力，使用趣味性被大大加强。
2.该石墨烯儿童垫，通过拼块组合成铺设层，支持自由组装，适合儿童拼装组接，有助于培养儿童的动手能力，并且拼块边缘的橡胶围沿具有非常好的结构弹性，能够使相邻拼块之间拼接牢固，不易松脱，且能够在儿童垫卷曲时，使各拼块之间具有良好的结构弹性，从而顺应儿童垫的卷曲动作，石墨烯夹层采用石墨烯材料支撑，具有非常好的导热性，能够将儿童垫本身所发出的热量进行高效率的传导，使得该儿童垫具有加热保热的功能，有助于提高儿童使用时的舒适度。
3.该石墨烯儿童垫，通过软胶中开设的槽隙，有助于将水漏下排出，避免水在铺设层上表面聚集，弹力层中设置有的橡胶气囊用于保证整个儿童垫的结构弹性，且该弹性主要针对有人力在儿童垫上造成压力时的情况，当人脚踩在铺设层上后，会使椭圆凸包向下压缩，椭圆凸包、通口和气口所形成的集气空腔受到压力，该集气空腔内的空气将会向下充入到橡胶气囊中，使橡胶气囊膨胀，当人脚离开后，橡胶气囊为恢复原来形态，将气排出到上述集气空腔，利用上述过程，抵消了儿童垫的形变受力，有助于维持儿童垫本身的厚度及结构，延长儿童垫的使用寿命。
4.该石墨烯儿童垫，通过膨胀胶条以及膨胀胶条内部设置的蓄水囊，承接来自于槽隙的漏水，使吸水层具有良好的吸水性能，膨胀胶条选用膨胀橡胶为主要材料，膨胀橡胶具有遇水后膨胀的作用效果，能够在蓄水囊意外破裂后，对破裂的蓄水囊产生包裹压迫的作用效果，从而防止水意外蔓延在吸水层中，对电热丝的通电工作造成影响，当电热丝通电后，利用其通电后自然产热的特性，一方面能够为儿童垫进行整体供热，提高使用舒适度，另一方面则能够对蓄水囊中所充入的水进行加热蒸发，从而消耗儿童垫内部存水，保持儿童垫内部处于无水或少水状态，避免儿童垫内部受潮发霉，水以漏水槽为主流道进入蓄水囊中，通过网格条的网格结构，使得水能够均匀输送至蓄水囊中。
5.该石墨烯儿童垫，通过海绵基构成底垫层这一儿童垫基层结构，海绵基上等距开设的张拉切槽用于保证海绵基本身具有良好的张拉性，能够满足儿童垫收卷后的外胀压力，亦能够在平铺时，在受到较大的压力(人力恶意、大力踩踏)时，通过一定的开口张度，缓解部分压力，从而有助于儿童垫快速恢复原来形态，橡胶吸盘用于将儿童垫吸附固定在地面或地板上，若儿童垫作为滑板使用时，则橡胶吸盘与地面地板相分开。

请参阅图1至图6，本发明提供一种技术方案：一种石墨烯儿童垫，包括垫体1、铺设层2和垫背7，垫体1包括铺设层2、粘附层3、弹力层4、吸水层5、底垫层6和垫背7，且铺设层2、粘附层3、弹力层4、吸水层5、底垫层6和垫背7依次层叠设置，垫体1的边缘包裹有封边8，且垫体1的四角均固定有金属镶块9，铺设层2由拼块10相互拼接而成，且拼块10的内部中层粘接有石墨烯夹层13，垫背7的表面中间嵌入有大环圈29，且大环圈29的左右两侧均连接连通有连接管30，连接管30远离大环圈29的一端连接有小环圈31，且小环圈31的末端安装有气嘴32，大环圈29的上下两侧均连接有行动胶管33，且行动胶管33嵌入在垫背7的表面上下两侧边缘，行动胶管33的外壁等距设置有安装槽34，且安装槽34的槽内安置有滚轮35，垫背7的正面四角均固定有橡胶吸盘36；
大环圈29和小环圈31均呈螺旋线管状结构，且大环圈29和小环圈31之间通过连接管30构成连通结构，安装槽34和滚轮35均沿行动胶管33的方向等距设置，通过气嘴32可以向左右两侧的小环圈31中分别注入压缩空气，空气经过小环圈31的螺旋线式环绕管路，经过连接管30充入到同为螺旋线管的大环圈29中，大环圈29中的气流又会进入到行动胶管33中，在上述充气的作用下，大环圈29、小环圈31、连接管30以及行动胶管33内部均处于膨胀状态，在大环圈29、小环圈31、连接管30以及行动胶管33内部气压增大的前提下，大环圈29、小环圈31、连接管30以及行动胶管33均具有了结构强度，且该强度大小与所注入气体的量的多少有直接关系，即所注入的气体越多，则大环圈29、小环圈31、连接管30以及行动胶管33强度越强，从而能够在儿童垫的垫背7位置，形成一层加固面，使得整个儿童垫的强度增大，平展在地面地板上时，不容易褶皱隆起，且在大环圈29、小环圈31、连接管30以及行动胶管33内部气量充入一定值后，大环圈29、小环圈31、连接管30以及行动胶管33的管道体积均会被撑大，尤其是行动胶管33，体积胀开后，则会呈现出图6所示的状态，即滚轮35会顶出，并能够与地面直接接触，形成整个儿童垫新的支撑结构，当儿童在儿童垫上坐着时，则可以借助这一结构，将该儿童垫转变成滑板，儿童垫不仅具有了结构强度，还具有了可以进行滑动的能力，使用趣味性被大大加强；
拼块10相互之间形状和尺寸均相吻合，且拼块10的外边缘固定有橡胶围沿11，拼块10的上表面中间固定设置有椭圆凸包12，且拼块10的内部中间竖向贯穿有通口14，拼块10的底面固定有粘布15，通过拼块10组合成铺设层2，支持自由组装，适合儿童拼装组接，有助于培养儿童的动手能力，并且拼块10边缘的橡胶围沿11具有非常好的结构弹性，能够使相邻拼块10之间拼接牢固，不易松脱，且能够在儿童垫卷曲时，使各拼块10之间具有良好的结构弹性，从而顺应儿童垫的卷曲动作，石墨烯夹层13采用石墨烯材料支撑，具有非常好的导热性，能够将儿童垫本身所发出的热量进行高效率的传导，使得该儿童垫具有加热保热的功能，有助于提高儿童使用时的舒适度；
粘附层3由软胶16构成，且软胶16的表面分别设置有气口17和槽隙18，槽隙18和气口17沿软胶16的短边方向间隔设置，且气口17沿槽隙18的方向呈一条直线均匀分布，气口17与通口14之间位置一一对应，且气口17与通口14之间相连相通，通过软胶16中开设的槽隙18，有助于将水漏下排出，避免水在铺设层2上表面聚集，弹力层4由硅胶垫19构成，且硅胶垫19的表面分别设置有漏水槽20和橡胶气囊22，漏水槽20和橡胶气囊22沿硅胶垫19的短边方向间隔设置，弹力层4中设置有的橡胶气囊22用于保证整个儿童垫的结构弹性，且该弹性主要针对有人力在儿童垫上造成压力时的情况，橡胶气囊22各自与气口17相连通，且橡胶气囊22沿漏水槽20的方向均匀设置，漏水槽20的两侧均固定有网格条21，且网格条21的内部呈网格状结构，当人脚踩在铺设层2上后，会使椭圆凸包12向下压缩，椭圆凸包12、通口14和气口17所形成的集气空腔受到压力，该集气空腔内的空气将会向下充入到橡胶气囊22中，使橡胶气囊22膨胀，当人脚离开后，橡胶气囊22为恢复原来形态，将气排出到上述集气空腔，利用上述过程，抵消了儿童垫的形变受力，有助于维持儿童垫本身的厚度及结构，延长儿童垫的使用寿命；
吸水层5由棉纱层23构成，且棉纱层23的表面分别设置有膨胀胶条24和电热丝25，膨胀胶条24和电热丝25沿棉纱层23的短边方向间隔设置，且膨胀胶条24和电热丝25之间相互平行，通过膨胀胶条24以及膨胀胶条24内部设置的蓄水囊26，承接来自于槽隙18的漏水，使吸水层5具有良好的吸水性能，膨胀胶条24的内部嵌入固定有蓄水囊26，且蓄水囊26与漏水槽20之间构成连通结构，膨胀胶条24选用膨胀橡胶为主要材料，膨胀橡胶具有遇水后膨胀的作用效果，能够在蓄水囊26意外破裂后，对破裂的蓄水囊26产生包裹压迫的作用效果，从而防止水意外蔓延在吸水层5中，对电热丝25的通电工作造成影响，当电热丝25通电后，利用其通电后自然产热的特性，一方面能够为儿童垫进行整体供热，提高使用舒适度，另一方面则能够对蓄水囊26中所充入的水进行加热蒸发，从而消耗儿童垫内部存水，保持儿童垫内部处于无水或少水状态，避免儿童垫内部受潮发霉，水以漏水槽20为主流道进入蓄水囊26中，通过网格条21的网格结构，使得水能够均匀输送至蓄水囊26中；
底垫层6由海绵基27构成，且海绵基27的表面等距开设有张拉切槽28，海绵基27上等距开设的张拉切槽28用于保证海绵基27本身具有良好的张拉性，能够满足儿童垫收卷后的外胀压力，亦能够在平铺时，在受到较大的压力(人力恶意、大力踩踏)时，通过一定的开口张度，缓解部分压力，从而有助于儿童垫快速恢复原来形态。
综上，该石墨烯儿童垫，使用前需要对垫体1进行组装，利用粘布15与软胶16之间类似于魔术贴的粘接方式，可以将拼块10以拼图的方式逐一粘拼在软胶16上，形成铺设层2，该过程可以由父母和儿童共同协作完成，在进行亲子活动的同时，更培养了儿童的动手以及思考能力，该儿童垫具有两种使用方式，一种是作为普通的垫子使用，即将该儿童垫平放在地面、地板即可，将橡胶吸盘36吸附在地面或地板上，对该儿童垫进行固定，为了避免儿童垫在儿童跑跳的影响下，出现褶皱或隆起的情况，可以通过气嘴32向小环圈31中打气，空气经过小环圈31的螺旋线式环绕管路，经过连接管30充入到同为螺旋线管的大环圈29中，大环圈29中的气流又会进入到行动胶管33中，在上述充气的作用下，大环圈29、小环圈31、连接管30以及行动胶管33内部逐渐处于膨胀状态，此过程对于空气的量并没有多少的限制，只要大环圈29、小环圈31、连接管30以及行动胶管33内部均充入气体，并保有一定的强度即可，此时儿童垫在气流充入的作用下，保持平展撑开的状态，从而不易发生褶皱或隆起的现象；
儿童在儿童垫上玩耍时，由于儿童控力有限，很有可能会在儿童垫上倾倒水流，水流经过拼块10之间的缝隙，被软胶16汇聚至各槽隙18中，并由槽隙18向下漏下至漏水槽20中，水以漏水槽20为主流道，以网格条21为分流道，均匀流至蓄水囊26中，最终在蓄水囊26中得到保存，从而达到该儿童垫收水的目的，该儿童垫内部具有加热结构，即电热丝25，当电热丝25通电后，利用其通电后自然产热的特性，一方面能够为儿童垫进行整体供热，提高使用舒适度，另一方面则能够对蓄水囊26中所充入的水进行加热蒸发，从而消耗儿童垫内部存水，使儿童垫内部处于无水或少水状态，避免儿童垫内部受潮发霉，该热量会逐渐上升传导至拼块10中，并由石墨烯夹层13的石墨烯材质均匀分散，以均匀透至儿童垫上表面，使儿童在儿童垫上玩耍时，不易着凉；
当人脚踩在铺设层2上后，会使椭圆凸包12向下压缩，椭圆凸包12、通口14和气口17所形成的集气空腔受到压力，其内部的空气将会向下充入到橡胶气囊22中，使橡胶气囊22膨胀，当人脚离开后，橡胶气囊22为恢复原来形态，将气排出到上述集气空腔中，利用上述过程，抵消了儿童垫的形变受力，同时也提高了人脚踩在儿童垫上的舒适度；
该儿童垫的另一种使用方式为，将儿童垫作为滑板使用，将橡胶吸盘36与地面或地板分开，通过气嘴32继续向小环圈31中充气，同上述原理，大环圈29、小环圈31、连接管30以及行动胶管33内部均充入气体，并在越来越多的充入气体作用下，越来越膨胀，大环圈29、小环圈31、连接管30以及行动胶管33的管道体积均会被撑大，尤其是行动胶管33，体积胀开后，则会呈现出图6所示的状态，即滚轮35会顶出，并能够与地面直接接触，形成整个儿童垫新的支撑结构，当儿童在儿童垫上坐着时，便可以借助这一结构，将该儿童垫转变成滑板，在地面上进行滑行，使得该儿童垫的趣味性被大大加强。
以上所述，仅为本发明较佳的具体实施方式，但本发明的保护范围并不局限于此，任何熟悉本技术领域的技术人员在本发明揭露的技术范围内，根据本发明的技术方案及其发明构思加以等同替换或改变，都应涵盖在本发明的保护范围之内。
