背景技术
现有的用于装填压缩气体的气瓶通常在开口处安装有相应的阀门来进行封装，以防止气体发生泄漏，且在对气瓶内的压缩气体进行使用时的控制更加方便。但是常用阀门安装在瓶口处的气密性通常并不是很好，容易出现气体的泄漏，相对于一些高压、易燃等气体来说存在非常大的安全隐患。且这类气瓶在生产时需要单独对瓶体和阀门进行组装，其内部的气体需要排放时，通常为通过在其外部安装连接管对气体进行输送，无法直接从气瓶的瓶口处到达所需的容腔中，通过管道进行输送的过程容易发生气体的泄漏，造成高压气体的泄压，使得进入容腔内的高压气体的压力难以到达规定值，对高压气体造成浪费，增加成本。

具体实施方式
下面将结合本实用新型实施例中的附图，对本实用新型实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本实用新型一部分实施例，而不是全部的实施例。基于本实用新型中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本实用新型保护的范围。

参见图1至图2，本优选实施例所述的气瓶包括瓶体1和连接件2，所述连接件2的两端开口设置，所述连接件2的第一开口端21固定连接于所述瓶体1的瓶口处，所述连接件2的第二开口端22密封连接有密封盖3，所述连接件2的内部设有与所述第一开口端21和所述第二开口端22相连通的通道23，所述通道23与所述瓶体1的内腔相连通，所述连接件2的外侧壁上设置有外螺纹4，所述气瓶的高度H为3cm～20cm。
基于以上结构，在对该气瓶进行生产时，连接在连接件2的第二开口端22处的密封盖3能够有效的保证瓶体1内部压缩二氧化碳气体的密封性，密封盖3与连接件2的第二开口端22的密封连接结构能够使瓶体1具有良好的气密性，避免采用阀门对瓶体1的瓶口进行密封时，因为阀门的工作性能所导致的瓶体2内的气体发生泄漏的现象，密封盖3与连接件2进行连接后，无需通过将二者进行分离来获取瓶体1内部的气体，即密封盖3与连接件2之间的密封效果不会发生改变，故而瓶体1内的气体不容易发生泄漏，对于高压气体来说，采用气瓶进行储存的安全性非常高，且该气瓶的结构设计简，生产和制造方便，成 本较低，适于进行推广使用。在对该气瓶进行使用时，能够通过连接件2的外侧壁上的外螺纹4对该气瓶进行安装，通过外力部件将位于连接件2的第二开口端22处的密封盖3顶破，即能够使得瓶体1内部的气体获得释放，这一过程具有两种操作方式，一种是先将气瓶通过连接件2的外侧壁上的外螺纹4进行固定安装，然后采用顶针或者其他部件将密封盖3戳破，以使得瓶体1内部的气体排放；另一种是将气瓶定位安装入内部设置有顶针或者其他部件的位置内，在随着通过外螺纹4将连接件2逐渐拧入的过程中，密封盖3能够逐渐向顶针或者其他部件靠近，直至接触，在连接件2继续螺接的过程中，密封盖3自动被顶针或者其他部件顶破，进而通过顶针或者其他部件将瓶体1的内腔中的高压气体进行释放。对该气瓶进行使用的过程非常简单，安装操作方便，且固定可靠，螺纹连接既能够保证气瓶安装的稳固可靠性，防止气瓶在释放高压气体的瞬间发生晃动或者被喷出，避免造成危险，且螺纹连接还能够方便对气瓶进行拆卸，进行维护和更换，过程简单可靠。该气瓶的高度H设置为3-20cm，整体的体积设计较小，重量轻，方便进行移动，使用时直接握持并安装即可，省时省力，非常便捷，且该气瓶的生产成本较低，便于批量生产。
其中，第二开口端22的边沿向内部延伸以形成向第二开口端22的中心凸出的内环24，密封盖3密封连接于内环24上，内环24能够为密封盖当的密封连接提供可靠的连接基础，方便密封盖3的定位安装，在本实施例中，密封盖3的外边缘与内环24相互铆接，有效的保证密封盖3在连接件2的第二开口端22处的气密效果的可靠性，不易发生泄漏，安全性能高。密封盖3的外表面上设有向连接件2的内部凹陷的凹部31，在需要进行高压气体的释放时，通过顶针或者其他部件将密封盖3顶破时，凹部31能够为顶针或者其他部件提供准确的定位，并未顶针或者其他部件提供一个集中的施力点，方便将密封盖3戳破，且避免顶针或者其他部件在密封盖3的表面上发生滑动，进而保证顶破的质量和效率。连接件2的第一开口端21与瓶体1的瓶口弧形过渡连接，能够使得气瓶的瓶体1与连接件2在连接处的结构强度更高，避免应力集中而出现破坏。
另外，瓶体1包括顺序相连通的瓶口部13、瓶身部12和瓶底部11，瓶身部12的外表面为圆柱形结构，瓶底部11和瓶口部12的外表面均为圆弧形面，在保证瓶体1内部容积的最大化的同时，圆弧形面更方便工作人员进行握持，在进行安装和拆卸的操作过程中，圆弧形外表面能够减弱瓶体1外形轮廓对工 作人员的手造成的伤害，使用和握持更加舒适，且方便对瓶体1进行储存和收集。瓶口部13的内径由靠近瓶身部12的一端向靠近连接件2的一端逐渐减小，且瓶口部13的最大外径、瓶底部11的最大外径分别与瓶身部12的外径相同，在瓶体1进行生产的过程中，瓶口部13做收口处理，既方便后续在瓶口处采用连接件2进行密封的操作，又方便在对高压气体进行释放时，高压气体从瓶口处喷出时对压力的保持。
优选的，连接件2为圆柱形件，连接件2的外径D1与瓶身部12的外径D2的比值范围为0.2～0.8，在本实施例中优选为0.4，最大化的保证瓶体1内的容积的同时，确保整个气瓶的结构强度，提高瓶体1内部的容积，并根据实际情况调整连接件2的外径以方便进行螺纹连接。连接件2的高度H1与瓶口部13的高度H2的与比值范围为：0.5～0.9，且瓶口部13的高度H2与瓶底部11的高度H3的比值范围为：0.4～0.9。连接件2的高度H1与瓶体1的高度H4的比值范围为0.1～0.5，在本实施例中优选为0.16，方便连接件2的长度能够为瓶体1的固定提供稳定的基础，避免瓶体1的长度相对于连接件2的长度过长而造成折断现象，提高整体结构的强度和质量。
在此需要说明的是，在本实施例中，连接件2和瓶体1为一体冲压成型，向瓶体1内部通入高压气体后在瓶口部13处进行拉伸和收口，并在连接件2的第二开口端22内通过铆接密封连接密封盖3，以保证整个气瓶结构的一体化加工，有效的确保其气密性，不容易发生泄漏。且气瓶的高度H限定为6-10cm，体积非常小，储存和使用方便，操作简单。密封盖3、连接件2和瓶体1均为金属件，结构强度高，承压能够强，进而保证在其内部储存高压气体的可靠性。但是在其他实施例中，密封盖3、连接件2、瓶体1之间的连接方式以及材料类型的选择并不受本实施例的限制，当可按照实际的需要，选择合适的连接方式和材料类型，只要能够保证气瓶的气密性和承压能力即可。
本实用新型的气瓶的结构中，通过在连接件的第二开口端处密封连接密封盖的方式对气弹内部的压缩二氧化碳气体进行封装，能够确保整个气瓶结构的气密性，避免气瓶因为受到阀门性能的影响发生气体泄漏，气瓶的连接件上的密封盖的结构可靠性高，与连接件形成固定的密封连接后无需通过将二者拆解的方式来获得气瓶内部气体的排放，有效的阻断气体被泄露的可能性，对于高压气体的储存来说，具备较高的安全性，且该气瓶的结构设计非常简单，便于 进行生产和制造。在对该气瓶进行使用时，能够通过连接件外侧壁上的外螺纹进行固定螺接，由外力部件将连接件的第二开口端处的密封盖顶破来实现气瓶内部压缩气体的释放，连接件通过外螺纹的固定连接即能够保证气弹在进行压力释放时的稳定性，又能够方便用户在气弹的压力释放完成后将其拆下进行更换和维护，使用非常方便，操作简单，且效果可靠。该气瓶的高度H为3-20cm，使得气瓶整体的体积小，且重量轻，便于移动进行安装拆卸的操作，适合进行批量生产。
应当理解的是，本实用新型中采用术语“第一”、“第二”等来描述各种信息，但这些信息不应限于这些术语，这些术语仅用来将同一类型的信息彼此区分开。例如，在不脱离本实用新型范围的情况下，“第一”信息也可以被称为“第二”信息，类似的，“第二”信息也可以被称为“第一”信息。
以上所述是本实用新型的优选实施方式，应当指出，对于本技术领域的普通技术人员来说，在不脱离本实用新型原理的前提下，还可以做出若干改进和变形，这些改进和变形也视为本实用新型的保护范围。
