Description

一种新型消防灭火器 技术领域
本发明涉及消防灭火器领域，特别涉及一种新型消防灭火器。
背景技术
泡沫灭火器能喷射出大量二氧化碳及泡沫，它们能粘附在可燃物上，使可燃物与空气隔绝，达到灭火的目的。现有技术的泡沫灭火器内有两个容器，分别盛放两种液体，它们是硫酸铝和碳酸氢钠溶液，分别放置在内筒和外筒，两种溶液互不接触，不发生任何化学反应。当需要泡沫灭火器时，把灭火器倒立，两种溶液混合在一起，就会产生大量的二氧化碳气体。这种泡沫灭火器，如果不小心倾倒，两张化学溶液就会反应生成大量二氧化碳气体，非常危险。且放置时间过长，碳酸氢钠容易分解，使得泡沫灭火剂失效。
发明内容
本发明的目的在于提供一种新型消防灭火器，解决上述现有技术问题中的一个或者多个。
本发明提供一种新型消防灭火器，包括灭火罐和泡沫发生器，灭火罐顶部设有手柄，手柄下安装有压把，压把与手柄连接处设有拉环，手柄前部连接有喷射管路，喷射管路前部安装有喷射嘴，泡沫发生器与喷射管路相连。本技术方案的灭火罐内罐装有CO2或者其他惰性气体，泡沫发生器内装有液体泡沫，最简单的设计为泡沫发生器内盛有水溶液，加入发泡剂后通过摇晃，产生大量泡沫。在使用时，首先拉开灭火罐与手柄之间设有的拉环，CO2气体通过喷射管路喷出，经过泡沫发生器，CO2气体带出液体泡沫成分，增加其灭火效率，其次消防员在灭火过程中，一手抓住手柄，按动手柄下部的压把，同时调整喷射嘴方向对准火源根部，通过喷射管路喷射出带有液体泡沫的CO2气体。
在一些实施方式中，泡沫发生器和喷射管路可拆卸式连接。可拆卸式连接，简单方便，能达到随拆随用的效果。且能及时更换发泡剂或补充发泡剂。
在一些实施方式中，泡沫发生器顶部设有具有外螺纹结构的连接元件，喷射管路内设有具有内螺纹结构的空腔，泡沫发生器的连接元件和喷射管路的空腔通过螺旋连接。如此设计，可以通过简单的旋转，来达到安装或拆卸的目的。
在一些实施方式中，喷射管路包括第一喷射管路和第二喷射管路，第一喷射管路与第二喷射管路相连，第一喷射管路和第二喷射管路之间设有挡板，第一喷射管路与泡沫发生器入口端相连，第二喷射管路与泡沫发生器出口端相连。如此设计，喷出的气体通过第一喷射管路进入泡沫发生器，带出液体泡沫，通过第二喷射管路喷出。
在一些实施方式中，泡沫发生器内设有进气管路和出气管路，进气管路与第一喷射管路相连，出气管路与第二喷射管路相连。进气管路的下端口低于发泡液的液面，出气管路的下端口高于发泡液的液面。如此设计，喷出的气体通过第一喷射管路进入泡沫发生器的进气管路，再通过泡沫发生器的出气管路，进入第二喷射管路后，通过喷射嘴喷出。
在一些实施方式中，灭火罐与手柄之间设有压力表。灭火罐与手柄之间设有压力表，可以查看灭火罐内气体的压力情况，避免高压气体泄漏导致灭火器失效。
附图说明
图1为本发明一实施方式中一种新型消防灭火器的结构示意图；
图2为本发明一实施方式中一种新型消防灭火器的局部结构示意图。
具体实施方式
下面结合说明书附图，对本发明进行进一步详细的说明。
如图1所示，
一种新型消防灭火器，包括灭火罐1和泡沫发生器6，灭火罐1顶部设有手柄2，手柄2下安装有压把3，压把3与手柄2连接处设有拉环4，手柄2前部连接有喷射管路7，喷射管路7前部安装有喷射嘴8，泡沫发生器6与喷射管路7相连。
为了装卸方便，泡沫发生器6和喷射管路7可拆卸式连接。
如图2所示，
泡沫发生器6顶部设有具有外螺纹结构的连接元件63，喷射管路7内设有具有内螺纹结构的空腔，泡沫发生器的连接元件63和喷射管路7的空腔通过螺旋连接。
喷射管路7包括第一喷射管路71和第二喷射管路72，第一喷射管路71与第二喷射管路72相连，第一喷射管路71和第二喷射管路72之间设有挡板73，第一喷射管路71与泡沫发生器6入口端相连，第二喷射管路72与泡沫发生器6出口端相连。如此设计，喷出气体带出泡沫发生器内的液体泡沫，增强灭火效果。
为了增加灭火效率，泡沫发生器6内设有进气管路61和出气管路62，进气管路61与第一喷射管路71相连，出气管路62与第二喷射管路相连72。进气管路61下端口低于液面，出气管路62下端口高于液面。
为了检查灭管罐1内的高压气体的压力状态，灭火罐1与手柄2之间设有压力表5。
工作原理：灭火罐内罐1装有CO2或者其他惰性气体，泡沫发生器6内盛有水溶液，加入发泡剂后通过摇晃，产生大量泡沫，通过泡沫发生器的连接件63螺旋固定于喷射管路7。在使用时，拉开灭火罐1与手柄2之间设有的拉环4，CO2气体通过喷射管路7喷出，其中CO2气体先经过第一喷射管路71，进入泡沫发生器6的进气管路61，CO2气体带出液体泡沫成分，通过泡沫发生器6的进气管路62进入第二喷射管路72，再通过喷射嘴8喷出进行灭火，以增加其灭火效率。
本发明提供的实施方案中的一种新型消防灭火器，通过气罐内的高压惰性气体，进入泡沫发生器，带出液体泡沫，增强灭火效果，且避免了泡沫灭火器容易倾倒失效的问题。
以上表述仅为本发明的优选方式，应当指出，对本领域的普通技术人员来说，在不脱离本发明创造构思的前提下，还可以做出若干变形和改进，这些也应视为本发明的保护范围之内。
