Abstract

本实用新型是打火机出气阀,包括阀体及置于其中带复位弹簧的出气管,出气管下端连接有密封头,阀体下端设有和密封头对应的进气孔,阀体底部设有节流块,该节流块中开有和阀体的进气孔连通的、上小下大的锥型孔。本实用新型能使气体经锥型孔和进气孔后进气量保持稳定,不受气温等影响,使火苗高度控制在设定的范围,安全性较好,并且结构简单,体积紧凑,装配容易。

Description

打火机出气阀
技术领域:本实用新型涉及一种气体打火机的出气阀。
背景技术:一般打火机的出气阀在底部设有进气孔和海绵,通过调节螺杆压缩海绵来控制进气量,进而影响出火高度。采用这种方式调节进气量相当不稳定,火苗易跳动,在气温不同时,也易变化难控制,使火苗高度不稳定,安全性能受影响。并且,现有的出气阀调节机构较复杂,成本较高,体积较大,装配布置麻烦。
发明内容:本实用新型是解决现有打火机出气阀的进气量难控制,使打火机火苗高度不稳定的问题。本实用新型包括阀体及置于其中带复位弹簧的出气管,出气管下端连接有密封头,阀体下端设有和密封头对应的进气孔,阀体底部设有节流块,该节流块中开有和阀体的进气孔连通的、上小下大的锥型孔。
在进气孔下方设上带锥型孔的节流块,气体先经锥型孔节流再进入出气孔,气流很稳定,火苗不易跳动,即使气温变化,气流也易稳定的控制,使火苗高度保持在一定范围,安全性能好。本实用新型的结构简单,装配容易,体积较紧凑,易布置构造。
下面结合附图和实施例进一步说明本实用新型。
附图说明:附图是实施例的主结构示意图。
实施例:如图所示,出气管6连同复位弹簧7置于阀体1中,出气管6侧壁还设有通孔8,密封头5连接在出气管6下端和阀体1设有的进气孔4对应。在阀体1底部设有节流块2,其中开有和进气孔4连通的、上小下大的锥型孔3。使用时拉动出气管6使密封头5不封住进气孔4,气体先经锥型孔3节流,再通过进气孔4进入阀体1内,再经出气管6侧壁的通孔8进入出气管6内腔。当出气管6被复位弹簧7复位时,密封头5封住进气孔4。由于一般要求火苗高度在2-4厘米间,可以将锥型孔3的上端口直径为0.3-0.4毫米,下端口直径为0.9-1.1毫米,高度为2.4-2.6毫米,阀体1的进气孔4直径为0.1-0.2毫米。当尺寸变动时,进气量也变化影响火苗。
