具体实施方式Detailed ways
下面结合附图及实施例对本实用新型进行详细说明。Below in conjunction with accompanying drawing and embodiment the utility model is described in detail.
如图2、3、4所示,本实用新型打气装置的较佳实施例,适用于连通安装在一个可被充气膨胀的物体900,而用以对该物体900进行充气,该物体900可以是气球、气垫或充气床等。该打气装置包含一个中空挠性的气囊机构3、一个安装于该气囊机构3中的弹簧4、一个安装于该气囊机构3的封闭套件5,及多个安装于该气囊机构3的复形件6。As shown in Figures 2, 3 and 4, the preferred embodiment of the utility model inflating device is suitable for connecting and installing on an
该气囊机构3包括一个内部界定出一个气室310的中空挠性软囊31,及分别连通安装于该软囊31的一个进气头32与一个止逆出气件33。该软囊31是由可挠性变形的不透气塑胶材料制成,具有一个底壁311、一个自该底壁311周缘往上突伸的环壁312,及一个固接于该环壁312顶缘且与该底壁311和环壁312相配合界定出该气室310的顶壁313。该进气头32是与该气室310连通地安装固定于该顶壁313。The
该止逆出气件33是安装固定于该环壁312,而与该气室310连通,并用以连通安装于所述待充气的物体900。该止逆出气件33是由软质塑胶材料制成,并呈扁平管状,包括两个上下相向叠靠地分别自该软囊31往外延伸,并以其两长侧边332相互连接的挠性塑胶薄片331,且塑胶薄片331的相向内侧面是呈平滑状,而可相向气密贴合。塑胶薄片331可在一个被该气室310挤出的气体冲开,而变成一个连通该气室310与该物体900的排气通道330的开启状态,及一个可被该气室310复形产生的负压吸力吸引而相向气密吸附贴合的封闭状态间变化。当其位于该开启状态时,可将气体导引入该物体900以进行充气,当其位于封闭状态时,会气密阻隔于该气室310与该物体900间。The non-return
该弹簧4是可被往下弹性压缩地安装于该软囊31中,并上下弹性顶抵于该顶壁313与该底壁311间,而恒具有将该软囊31上下撑展的弹力。The
复形件6是绕该软囊31轴心间隔分布地分别被包覆固定在该环壁312中,并呈直立片状,可随该软囊31的弯曲变形而一起弹性变形,并具有上下弹性展撑复形的弹力。复形件6是由弹性软质发泡材料制成,例如泡棉、乳胶…等发泡材料,可被弹性压缩变形,并可于压缩力量消失后自动弹性复形。The
该封闭套件5包括一个用以气密塞装于该进气头32而封闭该进气头32的塞块51,及一个用以螺锁固定于该进气头32而将该塞块51限位于该进气头32的盖体52。The
如图3、4、5所示,当要以本实用新型打气装置对所述物体900进行打气时,可将该封闭套件5拆离该进气头32,使该软囊31的气室310与外界连通。然后,可通过往下踩压该软囊31顶壁313的方式,迫使该软囊31的气室310被压缩变形,而将该气室310中的空气挤向该止逆出气件33,将该止逆出气件33自该封闭状态变化至该开启状态,也就是将塑胶薄片331冲开变成该排气通道330,而对该物体900充气,与此同时,该弹簧4会被压缩而蓄存复形弹力,复形件6也会随软囊31一起弹性变形,而积存复形弹力。As shown in Figures 3, 4, and 5, when the
当踩压该软囊31的力量消失后,该弹簧4的复形弹力会开始往上顶撑该软囊31的顶壁313,通过将该顶壁313往上顶移的方式,拉动已曲折变形的环壁312往上展撑复形,与此同时,固定于该环壁312的复形件6的复形弹力也会分别作用于该环壁312,可协助所在环壁312部位展开复形,借此双重弹力的同时作用,可加快该软囊31的复形速度。When the power to press the
此外,于该软囊31被压缩变形至极限,而已无气体再被挤进该止逆出气件33而冲开塑胶薄片331时,由于该止逆出气件33本身就是呈扁平状,所以塑胶薄片331会自动上下叠靠在一起。接着,于该软囊31被顶撑复形的同时,该气室310也会逐渐外张变大而相对该止逆出气件33产生一个负压吸力,此负压吸力会驱使塑胶薄片331相向气密贴合而封闭,使该止逆出气件33回复至该封闭状态,使得该物体900中的气体无法经由该止逆出气件33回流到该软囊31中,而达到止逆效果。In addition, when the
此外,当要收纳此打气装置时,可在将该软囊31被压缩的情况下,以该封闭套件5封闭该进气头32,防止气体再进入该气室310中,而可使该气囊机构3维持在体积较小的被压缩状态,且该软囊31中产生的负压吸力会驱使该止逆出气件33维持在气密封闭的状态。但是实施时,该打气装置的收纳方式不以此为限。In addition, when the inflating device is to be accommodated, the
在本实施例中,是在该环壁312周围间隔设置多个复形件6,但是实施时,只设置一个复形件6就可达到协助该环壁312复形的功效。In this embodiment, a plurality of
综上所述,通过在该环壁312设置软质弹性复形件6的结构设计,可利用该弹簧4的复形弹力与复形件6的复形弹力的双重力道的同时作用,提高驱使该软囊31复形的作用力,进而可在不增加弹簧4线径的情况下,相对加快该软囊31的复形速度,使得本实用新型打气装置的打气速度相对提高,再加上该止逆出气件33的结构设计,可通过两片塑胶薄片331的上下气密贴合作用,就可轻易达到止逆的目的,不需再采用一般止逆气嘴,可使打气装置结构更为简单,而有助于进一步降低制造成本与重量,相当方便实用。In summary, by setting the structural design of the soft elastic
