Description

气雾剂的安全保护装置 技术领域
本发明涉及一种保护装置，尤其涉及一种气雾剂的安全保护装置。
背景技术
随着经济的不断发展及科学技术的不断进步，为人们生产生活提供各种各样的物质消费品，从而丰富人们的生活水平，而气雾剂就是众多物质消费品中的一种。
气雾剂是指含药、乳液或混悬液与适宜的抛射剂共同装封于具有气雾阀的气雾罐中，使用时借助抛射剂的压力将内容物呈雾状物喷出的制剂，它包括气雾罐、加压于气雾罐内的加压材料、以将气雾罐内的加压材料喷射出来的气雾阀、配置于气雾阀的阀杆上以供操作人员通过按压方式去驱使阀杆而将气雾罐内的加压材料喷射出来的喷头及可移离地盖于气雾罐之顶部以遮盖喷头的盖子。故在使用时，操作人员先将盖子从气雾罐上取下，此时操作人员再通过按压喷头便可将气雾罐内的加压材料喷射出来；在不需要使用时，此时操作人员再将盖子盖合于气雾罐上即可。
但是，由于喷头是靠盖子所遮盖起来的，当儿童不小心接触到气雾剂时，他极容易地将盖子从气雾罐上取走，失去盖子遮盖的喷头处于暴露状态，则此时的儿童很容易地因按压喷头而产生误喷，一方面给儿童的人身安全带来风险，另一方面造成气雾剂的极大浪费；同时，在市场上销售的气雾剂中，通常都是将标签贴于气雾罐与盖子的接合处以识别该气剂雾在未被售出前是否被使用过，但这样标识的方式不可靠；同样，为了防止气雾剂在未被售出前是否被使用过，卖场的做法是将喷头取走，当消费者买了气雾剂后，再到卖场取回喷头，这样的做法十分的麻烦及不便。
因此，有必要提供一种防误喷、安全性好且有效确标识气雾剂在未被售出是否使用过的气雾剂的安全保护装置。
发明内容
本发明的目的在于提供一种防误喷、安全性好且有效确标识气雾剂在未被售出是否使用过的气雾剂的安全保护装置。
为实现上述目的，本发明的技术方案为：提供一种气雾剂的安全保护装置，设于气雾罐的顶部上，所述气雾罐的顶部封装有一气雾阀，所述气雾阀的阀杯包围所述气雾阀的阀杆，所述阀杯围出一容置腔，所述阀杆的上方配置有一喷头。其中，本发明的安全保护装置包括沿所述阀杆的轴向向下压入所述容置腔内并位于所述喷头下方的装置本体，所述装置本体与所述容置腔的腔壁相互挤压，所述容置腔内的装置本体阻挡所述喷头向下按压所述阀杆，且所述装置本体设有供操作人员将该装置本体从所述容置腔内撬起取走的撬起结构及用于标识所述装置本体从所述容置腔内撬出的标识结构。
较佳地，所述阀杆沿其轴向向上穿过所述装置本体，所述装置本体的轮廓分别与所述容置腔及阀杆相匹配。
较佳地，所述装置本体包含沿所述阀杆的轴向向下套设于所述阀杆上的圆管部及 由所述圆管部沿该圆管部的径向向外延伸出的圆环凸部，所述圆环凸部与所述容置腔相匹配，所述撬起结构及标识结构形成于所述圆环凸部上。
较佳地，所述圆环凸部与所述圆管部同轴布置。
较佳地，所述撬起结构至少为一个，所述撬起结构沿所述圆环凸部的周向布置，每个所述撬起结构对应一个所述标识结构。
较佳地，所述圆环凸部沿所述阀杆的轴向向上依次包含下圆环凸部及上圆环凸部，所述上圆环凸部与所述圆管部连成一体，所述下圆环凸部与所述上圆环凸部连成一体，且所述下圆环凸部沿所述圆管部的径向与所述圆管部相隔开，所述下圆环凸部的半径还大于所述上圆环凸部的半径。
较佳地，所述撬起结构包含槽孔及供撬起抵触用的抵触部，所述槽孔沿所述阀杆的轴向贯穿所述上圆环凸部及下圆环凸部，所述抵触部形成于所述上圆环凸部的下方部位处，所述标识结构为一遮盖片，所述遮盖片遮盖所述抵触部。
较佳地，所述遮盖片包含径向遮盖部分及轴向遮盖部分，所述轴向遮盖部分遮盖所述上圆环凸部的槽孔的侧壁，所述径向遮盖部分使所述上圆环凸部处的槽孔与下圆环凸部处的槽孔相隔开。
较佳地，所述上圆环凸部与所述下圆环凸部的接合处开设有环形凹槽，且所述下圆环凸部还沿所述阀杆的轴向开设有分隔槽，所述下圆环凸部的下端具有向所述圆管部的轴心处倾斜的倾斜结构。
较佳地，所述喷头移离地套设于所述阀杆上。
与现有技术相比，由于本发明的装置本体沿阀杆的轴向向下压入容置腔内并位于喷头下方，使得容置腔内的装置本体阻挡喷头向下按压阀杆，故未将装置本体从容置腔内撬出来时，此时的喷头是没法带动阀杆去将气雾罐内的气雾液喷射出来，因而有效地防止气雾剂误喷的发生，一方面保护了儿童的安全，另一方面能防止气雾剂的浪费。同时，由于本发明的装置本体设有供操作人员将该装置本体从容置腔内撬起取走的撬起结构及用于标识装置本体从容置腔内撬出的标识结构，故在气雾剂未被售出前，当要使用此气雾剂时就必须将装置本体从容置腔内撬出来，但撬出来后会导致标识结构的损坏，因此，消费者可以通过装置本体上的标识结构去识别气雾剂是否使用过，所以，本发明的安全保护装置能有效地标识气雾剂在未被售出前的使用情况，还具有结构简单的优点。

现在参考附图描述本发明的实施例，附图中类似的元件标号代表类似的元件。
请参阅图1至图3，本发明的气雾剂100包括气雾罐20、安全保护装置10及喷头30。气雾罐20内加压有气雾液，且气雾罐20的顶部具有封装有气雾阀20a，气雾阀20a的阀杯22包围气雾阀20a的阀杆21，且阀杯22围出一容置腔23；较优的是，在本实施例中，阀杯22为圆环形结构，以便于阀杯22的形成并封装于气雾罐20上，当然，在其它实施例中，阀杯22根据实际需要而设计为其它形状，故不以此为限；喷头30置配于阀杆21的上方，以供操作人员通过对喷头30的按压式操作而达到将气雾罐20内的气雾液喷射出去的目的，较优的是，喷头30移离地套设于阀杆21上，以满足喷头30在阀杆21上的装拆要求。
结合图4及图5，安全保护装置10设于气雾剂100的气雾罐20之顶部上，其包含沿阀杆21的轴向向下压入容置腔23内并位于喷头30下方的装置本体10a(见图3)，装置本体10a与容置腔23的腔壁231相互挤压，以防止装置本体10a从容置腔23内意外脱落；且容置腔23内的装置本体10a阻挡喷头30向下按压阀杆21，有效地防止气雾剂100被意外操作。且装置本体10a设有供操作人员将该装置本体10a从容置腔23内撬起取走的撬起结构13及用于标识装置本体10a是否从容置腔23内撬出的标识结构14，故在操作人员借助工具通过撬起结构13将容置腔23内的装置本体10a撬出时，此时工具会损坏标识结构14，因此，操作人员通过该标识结构14辨别本发明的气雾剂100是否属于首次使用的情况。具体地，如图1至图3所示，阀杆21沿其轴向向上穿过装置本体10a，装置本体10a的轮廓分别与容置腔23及阀杆21相匹配，以使装置本体10a更稳定可靠地置于容置腔23的腔壁231与阀杆21之间。更具体地，在本实施例中，装置本体10a包含沿阀杆21的轴向向下套设于阀杆21上的圆管部11及由圆管部11沿该圆管部11的径向向外延伸出的圆环凸部12，圆环凸部12与容置腔23相匹配，撬起结构13及标识结构14形成于圆环凸部12上，以使得本发明的安装保护装置10的结构更简单，还更稳定可靠地置于容置腔23的腔壁231及阀杆21之间；较优的是，圆环凸部12与圆管部11同轴布置，以便于装置本体10a的形成制造。
同时，撬起结构13至少为一个，而在本实施例中，撬起结构13为四个，四个撬起结构13沿圆环凸部12的周向布置，较优是呈等间隔的布置，每个撬起结构13对应一个标识结构14，当然，在其它实施例中，撬起结构13根据实际需要而设计为一个、二个、三个或五个不等，故不以上述的举例为限。如图5及图6所示，圆环凸部12沿阀杆21的轴向向上依次包含下圆环凸部122及上圆环凸部121，上圆环凸部121与圆管部11连成一体，下圆环凸部122与上圆环凸部121连成一体，且下圆环凸部122沿圆管部11的径向与圆管部11相隔开，从而使得下圆环凸部122因与圆管部11隔开而具有更可靠的弹性力，从而使得下圆环凸部122更可靠挤压于容置腔23内；且下圆环凸部122的半径还大于上圆环凸部121的半径，以使得装置本体10a更好的匹配容置腔23与阀杆21；较优的是，如图6所示，上圆环凸部121与下圆环凸部122的交接处开设有环形凹槽124，增加下圆环凸部122弹性收缩或活动的性能，一方面便于装置本体10a于容置腔23处的装拆，另一方面使得容置腔23内的装置本体10a与容置腔23的腔壁231的配合更紧密牢固。
如图3至图6所示，撬起结构13包含槽孔131及供撬起抵触用的抵触部132。槽孔131沿阀杆21的轴向贯穿上圆环凸部121及下圆环凸部122，较优的是，槽孔131呈半圆形的槽 孔，但不以此为限，抵触部132形成于上圆环凸部121的下方部位处。标识结构14为一遮盖片，遮盖片遮盖抵触部132，较优的是，遮盖片包含径向遮盖部分141及轴向遮盖部分142，轴向遮盖部分142遮盖上圆环凸部121的槽孔的侧壁，径向遮盖部分141使上圆环凸部121处的槽孔与下圆环凸部122处的槽孔相隔开，故在使用者借用工具将装置本体10a从容置腔23内撬出时，更容易损坏遮盖盖，从而达到更好的标识效果。为了使得装置本体10a更方便快捷地压入容置腔23内，故下圆环凸部122的下端具有向圆管部11的轴心处倾斜的倾斜结构123。
请参阅图7，展示了本发明的安全保护装置的另一实施例，该实施例的安全保护装置10`与前述的安全保护装置10的结构基本相同，区别点仅在于本实施例的安全保护装置10`的装置本体10a的圆管部11沿阀杆21的轴向向上超出上圆环凸部121而形成凸环结构，使得装置本体10a对喷头30的阻挡距离更长。由于本实施例的安全保护装置10`的其它结构与前述的安全保护装置10相同，故在此不再赘述。
请参阅图8，展示了本发明的安全保护装置的又一实施例，该实施例的安全保护装置10``与前述的安全保护装置10的结构基本相同，区别点仅在于本实施例的下圆环凸部122沿阀杆21的轴向开设有分隔槽1221，该分隔槽1221使下圆环凸部122分隔出相应数量的分隔块(即牙)，以增加下圆环凸部122弹性收缩或活动的性能，一方面使得装置本体10a与容置腔23之腔壁231抵压配合更紧密，另一方面更便于装置本体10a于容置腔23处的装拆。
与现有技术相比，由于本发明的装置本体10a沿阀杆21的轴向向下压入容置腔23内并位于喷头30下方，使得容置腔23内的装置本体10a阻挡喷头30向下按压阀杆21，故未将装置本体10a从容置腔23内撬出来时，此时的喷头30是没法带动阀杆21去将气雾罐20内的气雾液喷射出来，因而有效地防止气雾剂100误喷的发生，一方面保护了儿童的安全，另一方面能防止气雾剂100的浪费。同时，由于本发明的装置本体10a设有供操作人员将该装置本体10a从容置腔23内撬起取走的撬起结构13及用于标识装置本体10a从容置腔23内撬出的标识结构14，故在气雾剂100未被售出前，当要使用此气雾剂100时就必须将装置本体10a从容置腔23内撬出来，但撬出来后会导致标识结构14的损坏，因此，消费者可以通过装置本体10a上的标识结构14去识别气雾剂100是否使用过，所以，本发明的安全保护装置10、10`、10``能有效地标识气雾剂100在未被售出前的使用情况，还具有结构简单的优点。
上所揭露的仅为本发明的优选实施例而已，当然不能以此来限定本发明之权利范围，因此依本发明申请专利范围所作的等同变化，仍属本发明所涵盖的范围。
