The utility model relates to an explosion-proof lighter, which comprises a gas storage chamber and a shell located outside the gas storage chamber. The top of the gas storage chamber is also provided with a piezoelectric device, an air intake pipe is arranged in the gas storage chamber, an air valve is connected at the top of the air intake pipe, and a pressure relief explosion-proof chamber is arranged at the bottom of the gas storage chamber. The pressure relief explosion-proof chamber is separated from the gas storage chamber by an isolation layer and is isolated. There are ventilation holes on the layer, which are sealed by the provided sealing plug. When the pressure in the gas storage chamber increases to the preset value, the sealing plug is ejected, so that the gas storage chamber is connected with the pressure relief explosion-proof chamber to relieve pressure. The explosion-proof lighter is equipped with a pressure relief and explosion-proof chamber under the gas chamber. The pressure relief and explosion-proof chamber is separated from the gas storage chamber by an isolation layer with an air vent, and the air vent is equipped with a sealing plug, which makes the lighter in a high temperature environment and opens the sealing plug when the pressure in the gas storage chamber increases sharply to a certain extent, thereby making the gas chamber open. The internal gas flows into the pressure relief and explosion-proof chamber, which reduces the pressure in the gas chamber, thus achieving the function of self-explosion-proof.
【技术实现步骤摘要】
一种防爆打火机
本专利技术属于燃烧设备
,特别涉及一种防爆打火机。
技术介绍
打火机是小型取火装置,主要用于取火,吸烟,也用于炊事及其他取火。打火机今多用丁烷、丙烷类和石油液化气,它们经加压后充入贮气箱,一旦释放到空气中便吸热气化而迅速膨胀,极易点燃。现在市场上的打火机都是将气体液化后储存在塑料的储气室内,在高温或阳光暴晒时会使储气室内的压强急剧增大,造成打火机爆炸或泄露,如果打火机附近有易燃品就会造成一定的损失,比如火灾,汽车的自燃等,但是这些安全隐患将要发生时,并不能引起人们的注意。中国专利技术专利“防爆打火机”(专利号:CN105202574A)公开了一种防爆打火机,所述防爆打火机包括气体腔,夹层,注水口,密封塞,打气口,通过注水口可以把水或其它冷却液注入夹层;然而实际使用中,夹层的水或冷却液降温效果并不是很好。中国专利技术专利“一种防爆打火机”(专利公开号:CN103343980A),公开了一种防爆打火机,属于打火机安全防护
,在打火机本体的外壳上设有防爆减震层;与现有技术相比,采用在打火机本体的外壳上设置防爆减震层的方式,能够避免打火机因为震动、摔碰等原因而造成的爆炸等危险现象的发生,避免给人们的人身和财产带来严重的安全隐患;此结构侧重于减震处理,对于高温环境下,并不能起到防爆的效果。
技术实现思路
本专利技术的目的是针对上述现有技术的不足,提供一种防爆打火机,达到卸压防爆的目的。为解决以上技术问题,本专利技术采用的技术方案是:该防爆打火机,包括储气室以及设于储气室外围的壳体,储气室的顶部还设有压电装置,所述储气室内设有引气管,且引气管顶 ...
【技术保护点】
1.一种防爆打火机,包括储气室以及设于储气室外围的壳体,储气室的顶部还设有压电装置,所述储气室内设有引气管,且引气管顶部连接设有气阀,其特征在于:所述储气室的底部还设有卸压防爆室,卸压防爆室与储气室间采用隔离层分开,且隔离层上开设有通气孔,通气孔通过配设的密封塞密封;当储气室内的压强增大至预设值时,密封塞被弹开,使储气室与卸压防爆室连通卸压。
