Abstract

一种吹气防止泄漏口,它是在防漏气膜和气膜的吹气口之间装入一个可以向吹气口内凹进的防漏气口,防漏气口使用柔软的材料做成,可以向吹气口内侧凹进,可以向外侧拉,当他凹入时,防止气体向外漏出,凸出时,并不会对吹气口有影响。

Description

吹气防止泄漏口
技术领域
本实用新型涉及一种防止漏气的装置,主要用于充气用口内在充气口漏气。 
背景技术
目前,公知的充气口主要由一个封口层和一层内置的防泄漏口组成,但是现有的防漏气装置太过松散,尤其是在刚充入气,拔出充气装置的时候,容易漏气。常见的此类产品有救生圈,救生衣等。主要是由用不会漏气的材料做成一个封闭的物体,再这个物体内充气,可以做成各种形状。 
发明内容
为了克服现有的吹气口容易漏气的不足,本实用新型提供一种吹气防止泄漏口。它可以防止气体泄漏,对封闭性更加好。 
本实用新型解决其技术问题所采用的技术方案是:在防漏气膜和气膜的吹气口之间装入一个可以向吹气口内凹进的防漏气口,防漏气口使用柔软的材料做成,可以向吹气口内侧凹进,可以向外侧拉,当它凹入时,防止气体向外漏出,凸出时,并不会对吹气口有影响。在吹气口外有一层密封口,用于防止气体外漏,这是原本的构造,并不会对此造成影响。 
本实用新型的有益效果是,它可以有效防止漏气,增加密封性,构造简单,方便实用,实际应用效果显著。 
附图说明
下面结合附图和实施例对本实用新型进一步说明。 
图为本实用新型的构造示意图 
图中,1防漏气膜  2防漏气口  3吹气口  4封闭口 
具体实施方式
在图所示实施例中,在防漏气膜1上连接吹气口3,在吹气口3上增加防漏气口2,在吹气口3的最外侧是封闭口4。
