具体实施方式
请参考图1至图3所示,本实用新型中的空气压缩机装置,其整组装置包含有一盒体1、一补胶罐2、一串接软管4,于盒体1上设有一按压式的开关11及凹陷状的嵌接口12,该盒体1内部则设有一空气压缩机(图中未示出)。串接软管4的一端连结有一第一端头41,另一端的第二端头42则连结有一防喷接头5。补胶罐2以开口端21向下且底壁22朝上的型态被置设于盒体1的嵌接口12上,串接软管4的第一端头41卡扣于补胶罐2的出胶端管23,当进行补胎及充气等作业的阶段,串接软管4的第二端头42的防喷接头5可螺合于轮胎99的气嘴9,该盒体1接受汽车或其它DC电源启动后,即可让空气压缩机产生压缩空气并迫挤补胶罐2内的化学胶液由串接软管4处进入破损轮胎99内,即可达到修补轮胎99及充气等目的。
请参考图2至图8,本实用新型的主要特征即是具有可防止化学胶液产生暴冲射出的动作,亦即本实用新型在串接软管4的第二端头42上设有一止逆效用的防喷接头5,该防喷接头5的防喷构造具有一筒柱形套盖6(可同时参考图4),该套盖6内具有一内室60,该套盖6一端设一个具有阴螺纹的螺合孔61,而套盖6另端则有一透孔620,于邻近透孔620的内部形成有一口径略大于透孔620口径的凸环垣62,前述螺合孔61、内室60、透孔620为相连通。一圆筒形基座7(可参考图5),该基座7具有一圆筒室70,于圆筒室70靠近外侧段具有阴螺纹71,而相背于圆筒室70的基座7的另侧延伸出一阶梯状的连结端72,于连结端72内亦形成有一与圆筒室70相连通的通道73,该圆筒室70的内口径大于通道73的内口径,二者之间乃形成一阶梯状的平台74,而相邻于连结端72的基座7外侧面上设有一凹陷状的凹环段75,使基座7的外径大于凹环段75的外径,二者之间形成有一抵触阶76。
前述基座7的连结端72由套盖6的螺合孔61置于内室60并穿过凸环垣62的透孔620,该凸环垣62可抵触于基座7的抵触阶76,该外露于套盖6的基座7的连结端72可套结串接软管4的第二端头42,并可借由一固定环40将串接软管4与防喷接头5完全固定结合,如图3所示。
一弹簧51一端可置入于基座7的圆筒室70并抵于平台74上;一阀栓8(可同时参考图6),该阀栓8为一柱体81,于一端设有一外扩端头82,该外扩端头82外周边设有多个凹陷状的流通槽83,而柱体81及外扩端头82之间设有一颈段84,于柱体81上形成有多个相间隔的流通凹槽85;一阻塞环86套设于前述阀栓8的颈段84处;前述结合有阻塞环86的阀栓8由外扩端头82端置入基座7的圆筒室70并抵触于前述弹簧51的另一端,如图3所示;一顶柱锁头52(可同时参考图7),该顶柱锁头52内具有一中空室520,而顶柱锁头52的外周壁上设有一六角形凸垣521,于顶柱锁头52一端具有一斜锥壁522,且于斜锥壁522端顶柱锁头52外周边具有阳螺纹523;一密封环53可由顶柱锁头52的阳螺纹523端套设于顶柱锁头52并抵于六角形凸垣521上;将结合有密封环53的顶柱锁头52锁固于该设置有阻塞环86的阀栓8、弹簧51的基座7上,即顶柱锁头52的阳螺纹523与基座7的阴螺纹71相螺合固定,此时借由前述弹簧51的弹性张力,可使前述阀栓8结合的阻塞环86抵触于顶柱锁头52的斜锥壁522;一顶触垫54,其具有一完全穿透的流通口540,如图2所示,该顶触垫54可由套盖6的螺合孔61端置入,且顶触垫54套置于顶柱锁头52并抵触于六角形凸垣521上,如图3所示。前述阀栓8的流通凹槽85可穿伸于顶柱锁头52的中空室520、顶触垫54的流通口540并位于螺合孔61中。防喷接头5在无施予其他外力之下,其可利用弹簧51的弹性张力使套设于阀栓8的阻塞环86紧密地抵触于顶柱锁头52的斜锥壁522。
请参考图8所示的防喷接头5,不论是盒体1的开关11处于On(可同时参考图1)且化学胶液已被空气压力迫挤流动的状态下,由于阀栓8所结合的阻塞环86完全紧密接触于顶柱锁头52的斜锥壁522,使流通的化学胶液无法通过顶柱锁头52的中空室520,形成一个可防止化学胶液暴冲的保护机构。
请参阅图9及图10所示,该轮胎99的气嘴9内有一气芯组件91,该气芯组件91包含有一前接座92,其一端设有因具有圆形开口所形成一弧形的卡制垣921,且前接座92内存有一流通孔922;一中空套筒93,其一端设有一外卡垣931,而另一端则设有一气门座932;一气芯中心针94,该气芯中心针94为一柱体,于柱体上形成有多个相间隔的凸翼941;一气芯弹簧95可套进气芯中心针94柱体,其一端抵于气芯中心针94的凸翼941上;该套有气芯弹簧95的气芯中心针94可由外卡垣931端置入中空套筒93内,使气芯弹簧95的另一端抵触于气门座932,且气芯弹簧95外围可被中空套筒93所框围住;一气门阻塞环96,其套设固定于前述气芯中心针94柱体的一端上;将结合有气芯弹簧95、气芯中心针94、气门阻塞环96的中空套筒93与前接座92相结合,即前接座92利用卡制垣921卡扣于中空套筒93的外卡垣931,而气芯中心针94另一端穿伸出前接座92的流通孔922,在无施予其他外力之下,其可利用气芯弹簧95的弹性张力使套设于气芯中心针94的气门阻塞环96紧密地关闭中空套筒93的气门座932。
请参考图1及图9,当使用者将防喷接头5的螺合孔61与汽车轮胎99的气嘴9进行螺合时,该防喷接头5的阀栓8会先顶触并移动轮胎99气嘴9内的气芯中心针94,使气芯中心针94的气门阻塞环96离开原本所阻塞接触的中空套筒93的气门座932(可同时参考图10),而当使用者将防喷接头5的螺合孔61完全螺合于汽车轮胎99的气嘴9上,由于阀栓8受到气嘴9的气芯中心针94的碰触作用,该阀栓8右移压缩弹簧51导致阻塞环86离开原本所阻塞接触的顶柱锁头52的斜锥壁522,顶柱锁头52的中空室520形成可流通的通路状态,此时被空气所推动的化学胶液可经由基座7的通道73进入圆筒室70内,再行经阀栓8的外扩端头82的流通槽83并持续经由位于顶柱锁头52的中空室520内的阀栓8的流通凹槽85、顶触垫54的流通口540及螺合孔61,最后再经由气嘴9内的前接座92的流通孔922、中空套筒93及中空套筒93的气门座932而进入破损轮胎99内,如此即可达到灌胶进入轮胎99内进行补胎的动作,当然,压缩空气仍然可持续进入扁平轮胎99内进行充气至正常的胎压为止。
综观前论,本实用新型提供一种汽车轮胎99气嘴9与空气压缩机软管接头相结合的防喷构造,其具有防止使用者在不正确的操作步骤下所导致化学胶液发生暴冲射出的缺失。
